The object of this little book is to illustrate some of the notable buildings of Chicago, to touch briefly on some of the details of their electrical equipment and to emphasize incidentally—oh, quite incidentally !—the fact that in Chicago wherever there are motors to be started or stopped, slowed down cr speeded up, you will find Cutler-Hammer controllers. They are to be found in public buildings, office buildings and private residences. They are to be found in hotels, restaurants and theaters. They are to be found in department stores, printing plants and railroad depots. They are to be found in central stations, isolated plants and in every manufacturing industry where the electric drive is used. In short, as the Cutler-Hammer Near-Harmony Quartet sings at the annual dinner: Wherever motor hums or generator Grinds out the juice, yowll find it there; Field rheostat, starter or regulator, C-H CONTROL is everywhere. And it is. This booklet will convey some idea of the extensive use of Cutler-Hammer control in Chicago, and what is true of Chicago is true of practically every other important city in the country. In your own city—wherever you may live—you will find Cutler- Hammer controllers used in a majority of the electric power installations, and in Medinah Temple, where the delegates to the National Electric Light Association are foregathering as these pages go to press you will find, with one or two exceptions, nothing but Cutler- Hammer control. Medinah Temple, at Cass and Ohio Sts., within ten or fifteen minutes walk from the heart of the city, is the home of the Shriners in Chicago. The auditorium of the Temple—the largest in the city—has a seating capa- city of 5000, with an additional capacity of 1000 when seats are placed on the stage. The proscenic opening has a width of 70 feet, this opening being closed by a fire curtain nine inches thick and weighing, with its counterweights, over 40,000 pounds. This fire cur- tain is hydraulically operated, the water pressure being “SI6T ‘9 02 aunr—uoynwossy jybvT MMIII [DUOYDN AYR fo woNuoquo) YRxIS-AzLLY J, 24} 07 SazDbajeq sof suajsonbpwayy woyusauog ‘SLS OIHO GANV SSVO : ATIWNdAL HYNIGAW “aBDIS YJOWWDU 2Y} WO parDj)ad 2Q UDI szDas Jouoyippp punsnoy, PW—suossad puvsnoy} af ayopowwossn Ajqnp1ofuod [IN wnisojipND quarYfiubou svy J, s WNOAITXIOLIGAV HAL ATINAL HVNIGAW BANK OF CUTLER-HAMMER “SIMPLICITY” DIMMERS INSTALLED IN MEDINAH TEMPLE The thousands of lights on the stage and in the auditorium are dimmed or brightened at will by one man who controls all the lighting circuits from this switchboard. “CUTLER-HAMMER CONTROL IN CHICAGO SN secured by motor driven pumps under the control of Cutler-Hammer starters. There is a system of fans in the Medinah Temple designed especially with a view to keeping the audi- torium clear of smoke when smokers are held here. These fans are controlled by manually operated Cutler- Hammer starters of the Bulletin 3150 type and will clear the auditorium of smoke in a few minutes. The motors driving the main ventilating fans are also Cutler-Hammer controlled. Numerous other Cutler-Hammer controllers are used in connection with the electrically operated machinery installed in Medinah Temple. The dim- mers—one of the largest banks in Chicago— are of the Cutler-Hammer new “Simplicity” type, designed especially for use with tungsten lamps. The impressive ritual of the Shriners calls for striking lighting effects and these are obtained by the dimmers installed. Lectures are given every Sunday in the auditorium of the Temple, these being illustrated by a stereopticon. The lecturer, himself, controls all the lights in the auditorium by a remote control Cutler-Hammer magnetic switch of the Bulletin 6405 type, energized by a Cutler-Hammer pendent switch which he carries at the end of the cord in his pocket. THE OLD MEDINAH TEMPLE Fifth Ave. and Jackson Blvd. PEOPLES GAS BUILDING MICHIGAN BOULEVARD and ADAMS ST. The Chicago Offices of The Cutler-Hammer Mfg. Co., of Milwaukee, are located in the thirteenth floor of this building. “CUTLER-HAMMER CONTROL IN CHICAGO PEOPLES GAS BUILDING On the thirteenth floor of the building illustrated on opposite page the Chicago Offices of The Cutler-Ham- mer Mfg. Co. are located. The engineers connected with this office were trained in the Cutler-Hammer factory and have at their command the vast amount of valuable data concerning problems involving the control of electric motors, which has been accumulated during the many years The Cutler-Hammer Mfg. Co. has been engaged in this line of work. A cordial invitation to avail themselves of this information is extended to all interested in the control of electrical apparatus. The Peoples Gas Building is located on the corner of Michigan Boulevard and Adams St. directly opposite the Art Institute. It is 22 stories high, or 260 feet. The granite columns on the ground floor are mono- lithic and weigh about 30,000 pounds apiece. The total cost of the building was $8,000,000. All of the con- trollers used in this magnificent structure, with the single exception of the elevator equipment, are of Cutler- Hammer design and manufacture. In all there are oe USA SUB-BASEMENT OF PEOPLES GAS BUILDING Cutler-Hammer controllers on the left and on the back wall. PNEUMATIC TUBE SYSTEM INSTALLED IN THE PEOPLES GAS BUILDING The lower illustration shows the Cutler-Hammer controller which automatically regulates the vacuum according to the number of tubes in use. 11 ~ CUTLER-HAMMER CONTROL | IN CHICAGO some 126 motors installed in this building, ranging in size from one-eighth to 100 H. P. In the sub-basement machine room are located most of the pumps used in the building. Here will be found two brine pumps, two drinking water pumps, three house pumps, one fresh air fan, one air washer, two gas boosters, and an ice machine. All of these are driven by motors handled by Cutler-Hammer controllers. The controllers for the house pumps are of the self- starter type, the two smaller ones being controlled by a special duplex self-starter panel and the other by a self-starter of the Bulletin 6160 type. The gas boosters are controlled by self-starters which are automatically started and stopped by variations in the gas pressure, the starting and stopping of these boosters being immediately controlled by a mercury “U” tube connected to the gas mains. The pneumatic tube system installed in this building facilitates the transmission of reports, correspondence, etc. between the various departments of the Peoples Gas Co. This installation consists of two motor driven vacuum pumps, each of 15 H. P. capacity, these being controlled by special Cutler-Hammer automatic speed regulators which are designed to vary the speed of the motor according to the number of carriers which are being transmitted through the tubes at any given moment. The motors are controlled through the medium of vacuum dash-pots which regulate the speed of the motor to maintain the vacuum practically constant irrespective of the number of tubes in use. The two cylinders shown in lower illustration on page 10 are piped to the vacuum system, the piston in the cylinders traveling up or down as vacuum con- ditions vary and in so doing carrying with them the master levers that regulate the speed of the motors driving the vacuum pumps. The upper illustration on page 10 shows the transfer station of the pnuematic tube system. To this room are brought the terminals of the fifty tubes, every carrier in the system being dispatched to this room and there transferred to the tube connecting with the department to which it is addressed. The transfer station attendant handles an average of 5000 carriers per day. A 100 H. P. Cutler-Hammer fire pump starter of the Bulletin 6311 type is installed in the basement of the Peoples Gas Building. This is designed to maintain a constant pressure on the sprinkler system and fire hose outlets at all hours of the day or night. CONTINENTAL AND COMMERCIAL NATIONAL BANK BLDG. This magnificent building now being erected at Adams and La Salle streets covers an entire city block and will be the largest bank building in the world. Cutler-Hammer controllers have been specified for the entire building. 13 CUTLER-HAMMER CONTROL IN CHICAGO OFFICE BUILDINGS The principal applications of Cutler-Hammer control in office buildings in Chicago are in connection with motors operating ventilating fans, controlled by speed regulators of the Bulletin 3250 type; house pumps, con- trolled usually by self-starters of the types known as Bulletins 6140, 6141 and 6161; drinking water pumps, brine pumps and refrigerating machinery, controlled either by hand starters of the Bulletin 2150 type or by speed regulators of the types listed in Cutler-Hammer Bulletins 3150 and 3250. In the majority of these buildings will also be found pneumatic sewage ejectors, motors for which are controlled by various kinds of Cutler-Hammer self-starters used in connec- tion with Bulletin 6750 or Bulletin 6760 pressure gauges. This type of ejector disposes of the waste water by air pressure instead of pumping it out of the building. In office buildings having their own power plants will usually be found Cutler-Hammer field rheostats on the generators, and either starters or speed regulators on the stokers. The tendency in recent years has been to automatically maintain a constant boiler pressure by a forced draft through the fire box. This is secured by means of motor driven draft fans the operation of . a Lo Pilea oy ogy NTE Seg tay UN GB tina ing UREN ea vagy Onan arias Lis : FIRST NATIONAL BANK BUILDING RAILWAY EXCHANGE BUILDING 2 BELL TELEPHONE BUILDING This building—212 West Washington St.—is the main exchange of the Chicago Telephone Company. The 35 H.

The Insurance Exchange Building (Jackson Boule- vard and Fifth Ave.) is typical of the larger office buildings. With the exception of the elevators, all motors are Cutler-Hammer controlled. The speed regulators in this building are a modification of the standard Bulletin 3250 type, circuit breakers being substituted for the usual knife-switch and fuses. The motors driving the house pumps, are provided with Bulletin 6161 self-starters similarly modified by the addition of circuit breakers. Other machines, such as air washers, etc., are controlled by special starting panels of the Bulletin 2150 type, plus circuit breakers. What will be the largest bank building in the world when completed is now being erected by the Con- tinental & Commercial National Bank. This hand- some structure is located at the corner of Adams and La Salle Sts. and covers an entire city block.

The apparatus specified includes controllers for the ventilating fans, drinking water pumps, house pumps, sewage ejectors, air washers and brine pumps, eighteen of these varying from 3 H. P.to65 H.P. The size of this building is well illustrated by the fact. that three 20 H. P. motors will be used to replace the water drawn from the house tanks. These three motors are controlled by a special triplex self-starter panel which is so arranged that by one operation of the master switch it is possible to start any one of the three motors and afterwards to start either of the other two, an arrangement designed to equalize wear and tear on the several units comprising the installation. The Steger Building (Jackson Boulevard and Wabash Ave.) is equipped throughout with Cutler- Hammer control. An interesting feature of this in- stallation is the use of special elevator controllers on the high-speed direct traction elevators. There are three of these equipments in this building, as well as three standard Cutler-Hammer Bulletin 7110 elevator controllers and one Bulletin 7240 sidewalk lift.

The controllers—Schureman Type M—are described in Cutler-Hammer Bulletin 7560. Wabash Ave. and Jackson Boulevard. Special type of Cutler-Hammer elevator controller installed in the Steger Building. 19 IN CHICAGO In the Karpen Building (Michigan Boulevard and Taylor St.) there is a Cutler-Hammer vacuum sweeper controller designed to vary the speed of the motor so as to produce the proper vacuum for sweeping regard- less of whether only one or a dozen sweepers are in operation. In the Transportation Building (Dearborn and Harrison Sts.) will be found speed regulators and self- starters of the usual office building types; also an interesting installation of fourteen elevators operated by Cutler-Hammer controllers. In this building is also housed a large wireless station in which the motor generator set is under the control of Cutler-Hammer starters and field regulators. The editorial offices of the Electrical Review are located in this building. In some of the newer office buildings, such as the Hill Building and the Barnheisel Building will be found interesting installations of Cutler-Hammer high speed passenger elevator controllers. In the Boddie Building (5828 Washington Ave.) and at the Methodists Old Peoples Home (1415 Foster Ave.) may be seen elevators operated by Cutler- Hammer push-button controllers. HARRIS TRUST & SAVINGS BANK MARQUETTE BUILDING IN CHICAGO EQ PUBLIC BUILDINGS The public buildings of Chicago, with the exception of the Field Museum of Natural History in Jackson Park, are all located in the business center of the city each within easy walking distance of the others. ART INSTITUTE This handsome building is on Michigan Boulevard at the foot of Adams St. and is directly opposite the Peoples Gas Building in which the Chicago Offices of The Cutler-Hammer Mfg. Co. are located. It contains a most valuable and interesting collection of paintings and sculpture and in addition to the per- manent exhibits is frequently used for temporary exhibitions of various kinds which are attended by half a million people a year. Admission to the Art Institute is free on Wednesdays, Saturdays, Sundays and holidays. On other days an admission fee of 25 cents is charged. The hours during which the building is open to the public are 9 A. M. to 5 P. M. on week days and 1 to 5 P. M. on Sundays. There are installed in the Art Institute a total of thirty motors, used for various purposes, all of which are equipped with Cutler-Hammer controllers. There are 18 motors on the ventilating system, ranging from one to 14 H. P., on which speed regulators of the Bulletin 3110 type are used. The freight ‘elevator controller is driven by a 5 H. P. motor equipped with a Cutler-Hammer, Schureman type, elevator controller and the air compressor installed here is also under Cutler-Hammer control. PUBLIC LIBRARY The Public Library, Michigan Boulevard and Washington St.,is three blocks north of the Art In- stitute. Here will be found a most complete collec- tion of books of reference, scientific and historial works, poetry, fiction, ete. Visitors to Chicago who yearn for news from home will find on file in the Public Library reading room newspapers from every important city in the United States. On the second floor of the building is a museum of war relics and battle flags, together with a life size mpenrenmeosiies, POST OFFICE portrait of Abraham Lincoln and portraits of other leaders of the Civil War. The Library is open to the public from 9 A. M. to 10 P. M. on week days and from 9 A. M. to 6 P. M. on Sun- days. The Library has its own power plant, which consists of four 200 H.P., cross- head type steam engines driving 60 K. WW. generators these being of the 3-wire type. There are installed in this building, fourteen ventilating fans driven by motors ranging from one to 15 H. P. these being controlled by Cutler-Hammer, Bulletin 3110, speed regulators. On the pneumatic tube system, there is installed a Cutler-Ham- mer, manually operated, starting rheostat of the Bulletin 2110 type this being used in connection with a 5 H. P., 220 volt motor. The ash conveyor is also driven by a 5 H. P. motor equipped with a similar type of control. 23 ‘CUTLER-HAMMER CONTROL ‘| IN CHICAGO 1 FIELD MUSEUM The Field Museum of Natural History is in Jackson Park and is most conveniently reached after a visit to the Public Library by taking an Illinois Central suburban train from the depot which is almost directly oppose the Library. It may also be reached by the South Side Elevated railroad or Cottage Grove Avenue surface car. The Field Museum building is a relic of the Colum- bian Exposition held in Jackson Park in 1893, having been the Fine Arts Building of the exposition. It is located near the north end of the Park and the exhibits are arranged in four distinct groups—Anthropology, Botany, Geology and Zoology. A fee of twenty-five cents is charged for admission to the museum except on Saturdays and Sundays when admission is free. The building is open to the public from 9 A. M. to 4 P. M. The extremely valuable collections of the Field Museum of Natural History are protected against damage by fire by an alternating current fire pump equipment controlled by a Cutler-Hammer fire pump starter of the Bulletin 9665 type. POST OFFICE The Post Office is another very interesting example of the universal use of Cutler-Hammer control. ‘The postal clerks in this building handle every day from 600 to 700 tons of mail matter and about 125 tons of parcel post. This matter from the time it enters the building until it leaves is handled by overhead conveyors driven by motors controlled by various types of Cutler- Hammer apparatus. The cancelling machines, as well as the various other labor-saving machines used in the postal service are also under Cutler-Hammer control. Aside from the control of mail handling machinery Cutler-Hammer apparatus is used in this building in connection with the motors operating ventilating fans and the various types of pumps with which the Post Office is equipped. In the same building the sessions of the Federal Courts are held, and here also are to be found the offices of the various departments of the National Government, such as the Treasury Department, Custom House, Internal Revenue, Bureau of the Census, etc. ELEVATOR MACHINE Board of Trade Bldg. BOARD OF TRADE BUILDING Jackson Boulevard and La Salle St. Cutler-Hammer—Schureman Type—elevator controllers of special design. 25 CITY HALL In the City Hall and County Building will be found two 150 H. P. motor-driven fire pumps, controlled by combined manual and automatic starters of the Cutler- Hammer Bulletin 6311 type. These equipments are designed to maintain a constant water pressure of 100 pounds per square inch on the sprinkler system and fire hose outlets. There will also be found in this building six house pumps, four of which are driven by 40 H. P. motors and two by 25 H. P. motors, all of these being under the control of Cutler-Hammer self- starters of the Bulletin 6161 type. Other apparatus includes a self-starter used in connection with a 10 H. P. motor driven air compressor, and a coal con- veyor, also driven by a 10 H. P. motor, this being under the control of a Cutler-Hammer Bulletin 2150 manually operated motor starter. BOARD OF TRADE Although strictly speaking the Board of Trade is not a public building it is mentioned here because it is one of the show places of the city and has a large gallery to which visitors are freely admitted and from which a good view of the animated scene on the trading floor may be obtained. The hours when visitors are admitted to the gallery are from 9.30 A. M. to 1.15 P. M. except on Saturdays, when trading is suspended at noon. An interesting installation in this building consists of five electric elevators of unusual design, inasmuch as the motors, instead of being installed at the top or bottom of the hatchway, are made to serve as counter- weights to the car and travel up and down the hatch by means of pinions which engage racks placed on either side of the guide posts. The cut on page 24 illustrates the mechanism described as well as the special Cutler-Hammer, Schureman type, controllers used in connection with this installation. In the Board of Trade Building will also be found a centrifugal booster pump driven by a one and one-half horsepower motor, and a hot well pump driven by a 3 H. P. motor. The booster pump motor is controlled by a Cutler-Hammer manually-operated starting rheostat of the Bulletin 2110 type and the hot well pump by a Bulletin 6140 self-starter operated by a float switch. 27 EDUCATIONAL INSTITUTIONS Chicago boasts of many fine schools and colleges, the fame of which attract students from all parts of the country. Foremost among these is the University of Chicago, easily reached by taking a Cottage Grove Ave. car to 59th St., and walking four blocks east. The campus fronts on the Midway Plaisance, the connecting link between Washington and Jackson Parks, and while in this neighborhood the latter should be visited, as it contains the Field Museum of National History and a number of other buildings that formed part of the great Columbian Exposition held here in 1893. Here also, at anchor in one of the lakes, are exact repro- ductions of the three tiny caravels:in which Columbus and his men made their memorable voyage of discovery. Among the many installations of Cutler-Hammer control in educational institutions is a complete equip- ment in the Lane Technical High School of Chicago. In this building the ventilating fan motors are con- trolled by Cutler-Hammer speed regulators, the pump motors by Cutler-Hammer self-starters and the same types of apparatus are installed in connection with the various machines used throughout the building for the instruction of students. Among these machines are the woodworking lathes, which are equipped entirely with Cutler-Hammer Bulletin 2230 variable speed regulators. The Lane Technical High School maintains its own power plant. For the control of the generator fields Cutler-Hammer field regulators are used. A recent addition to the educational institutions of Chicago is the Hyde Park High School. This build- ing is equipped with alternating current, motor driven ventilating fans, which are controlled by secondary drum type speed regulators, of the Cutler-Hammer Bulletin 9365 type. The Armour Institute of Technology (Armour Ave. and 33rd St.) and the Lewis Institute, (1955 West Madison St.) both of which are well known for their electrical courses, use Cutler-Hammer control in con- nection with the various motors installed in their build- ings and employ the same class of apparatus for the instruction of their students. Notable among the educational institutions of the country are the University of Chicago (Midway Plaisance, Jackson Park) and the Northwestern Uni- versity, (at Evanston) where Cutler-Hammer con- trollers of various types will be also found in the class rooms as well as in the basement. 29 HOTELS The fine hotels of Chicago—and they are among the finest in the world—contain many interesting instal- lations of Cutler-Hammer apparatus. A brief enu- meration of the principal types of control used may be of interest. For the motors driving the ventilating fans Cutler- Hammer manually operated speed regulators (Bulletin 3150 or 3250) are usually specified. The house pumps are generally controlled by self-starters of the types listed in Bulletins 6105, 6140, 6141, 6160 and 6161. Such machines as the drinking water pumps and brine pumps, used for cooling the drinking water, are controlled either by speed regulators of the Bulletin 3110 or 3150 type, or by motor starters such as are listed in Bulletin 2110 and 2150. Similar types of con- trol are used in connection with the cold storage and refrigerating machinery. Practically every modern hotel in Chicago maintains its own laundry, usually located in the top floor of the building, and here nothing but Cutler-Hammer con- trollers will be found. In the boiler room the automatic stokers which lighten the labor of the firemen are motor driven, and here once again is encountered—Cutler-Hammer! control. The Hotel La Salle, (corner Madison and La Salle Sts.) maintains its own electrical plant, the current being supplied by three generators of 250 K. W.—350 K. W. and 500 K. W. capacity. More than one hundred motors are installed in this hotel. Eighteen motors, ranging in size from 1 H. P. to 28 H. P. are used in connection with the ventilating system. Twenty-three motors are installed in the laundry, these ranging from one-quarter to 15 H. P. One 10 H. P. motor operates the coal conveyor and five motors of 3 H. P. each are used in connection with the auto- matic stokers. Twenty motors of one-half to 3 H. P. are used in the kitchen and pantry in connection with the dough mixer, meat and vegetable choppers, potato peeler, potato masher, dish washer, buffers for glass and silver, ice-cream freezer, cream separator, ice saw, elevator and dining room signals, etc. Other motors are required for the air compressor, vacuum tube systems, the numerous pumps, etc., and in connection with all of these various applications of the electric drive Cutler-Hammer control is used. At the Hotel Sherman (Clark and Randolph Sts.) the motor equipment aggregates 660 H. P., of which 450 H. P. is required for operating the ventilating fans. CONGRESS HOTEL 31 CUTLER-HAMMER C IN CHICAGO The various other motor applications and the types of controllers used are similar to those of the Hotel La Salle, the resemblance extending even to the print shop where menus and house stationery are printed. At the Congress Hotel (Michigan Boulevard and Congress St.), and at practically every other first-class hotel in the city, Cutler-Hammer controllers are to be found; but since the electrical equipment of one hotel resembles that of another the description already given will serve for all. Mention should be made, however, of an interesting dumb-waiter installation at the Hyde Park Hotel (51st St. and Lake Ave.) where a 3 H. P. motor operat- ing the dumb-waiter is controlled by a Cutler-Hammer Bulletin 7570, eight-landing, dumb-waiter controller. At the famous College Inn, located in the basement of the Hotel Sherman; at the equally famous Blue Fountain Inn, in the basement of the Hotel La Salle; and at the renowned Pompeian Room in the Congress Hotel all of the ventilating fan motors are under the control of Cutler-Hammer apparatus. PALMER HOUSE Monroe and State Sts. CLUBS The social life of Chicago would not be complete without its clubs, many of which are housed in magni- ficent buildings of their own. Three of city’s leading clubs—Chi- cago Athletic Club, Illinois Athletic Association and the University Club are located on Michigan Boulevard between Adams and Madison Sts. The Chicago Club is also on Michigan Boulevard, corner of Van Buren St. The Hamilton Club is on Dearborn St. between Monroe and Madison, and the Union League Club is on Jackson Boulevard, corner of Federal St. The Engineer’s Club is on Federal St. ad- joining the Union League Club. Cutler-Hammer control is widely used in club houses in Chicago the principal applications being in connection with motors driving the ventilating fans and house pumps. At the University Club, Chicago Athletic Club and Illinois Athletic Association the ventilating fan motors are equipped with Cutler- Hammer manually-operated starting rheostats and the house pump motors with Cutler-Hammer self-starters. 33 CUTLER-HAMMER CONTROL. IN CHICAGO THEATERS Chicago is famed for the large number of beautiful theaters it possesses, being rivaled in this respect only by New York. Of theaters playing high-class attrac- tions, vaudeville and variety there are about fifty in all, to say nothing of moving picture houses which are numbered by hundreds. It is interesting to note in this connection that the first theater in the world to install incandescent lamps was the Academy of Music, on South Halsted St. The theater was wired for 150 incandescent lamps, the electric illumination being confined to the auditorium, since owing to the absence of dimmers in those days it was necessary to continue the use of gas for stage lighting. The first theater to use incandescent lamps for stage lighting was the old Haverly Theater, then located on Monroe street between Clark and Dearborn where the Inter-Ocean building now stands. The generating plant consisted of two dynamos which supplied current for 637 lamps. The startling brilliancy of the new illuminant, to eyes accustomed only to gas light, created a great sensation on the opening night and the innovation was so successful that similar lighting plants were immediately installed by McVicker’s Theater (West Madison St.) and the Chicago Opera House (West Washington St.) the latter now being razed to make way for a new business block—the Conway building. In the early days of electric stage lighting it was cus- tomary to place as many as 150 lamps on one circuit, and the early type of dimmer was correspondingly large and heavy. Later on the Cutler-Hammer “Simplicity” type dimmer was designed in the form of a compact circular plate controlling a maximum of fifty 16-candlepower lamps. Any desired number of these plates could be conveniently banked in an angle iron frame. Each plate controlled one circuit and was operated by a small lever. Each group of plates was controlled by a master lever and all of the plates were arranged to be operated in unison by a grand master. The ‘‘Simplicity”’ dimmer swept the country and was speedily installed by all the leading theaters. Various improvements, all tending toward greater refinement of control, have been made from time to time in this type of dimmer and quite recently an entirely new plate has been placed on the market with a view to meeting the demand for a dimmer suitable for use with BLACKSTONE THEATER Wabash Avenue and Hubbard Place. ILLINOIS THEATER Jackson Boulevard between Wabash Avenue and Michigan Boulevard. 35 CUTLER-HAMMER CONTROL NC metallic filament lamps. High efficiency metallic filament lamps require a large number of resistance steps in order that the dimming may be gradual and free from flickering. This condition is successfully met in the new type of “Simplicity” dimmer. Two large dimmer installations in which this new type of plate is used have already been made in Chicago—one in the Auditorium (Wabash Ave. and Congress St.) and the other in the new Medinah Temple (Cass and Ohio Sts.) These banks are illustrated on page 36 and page 8 of this booklet. The Blackstone, one of Chicago’s newest theaters, has a representative bank of Cutler-Hammer dimmers. This theater has also installed a number of speed regu- lators of the Cutler-Hammer Bulletin 3250 type, these being used in connection with motors driving the ven- tilating fans. This beautifully appointed play-house is located at the corner of Wabash Ave. and Hubbard Place, just back of the Blackstone Hotel, which fronts on Michigan Boulevard. The Illinois Theater, one of the oldest in Chicago, still uses an early type of Cutler-Hammer “‘iron-clad”’ dimmer which, in spite of its many years of service, is still in such good condition that the management will not consider replacing it with a newer type. This theater is on Jackson Boulevard between Wabash Avenue and Michigan Boulevard, just back of the Hotel Stratford. The Majestic Theater (Monroe St. between Dear- born and State) has a fine bank of Cutler-Hammer dimmers with wheel drive, this device giving a refine- ment of control much superior to that which can be obtained by the use of hand levers. The curtain in this theater is raised and lowered electrically by push- button control. The building in which the Majestic Theater is located generates its own power by means of 2-wire, 220 volt generators. The lighting circuits throughout the building and theater are 110 volts, secured by means of a special balancer set installed in the generator room. The unbalanced loads are taken care of by Cutler-Hammer polarized relays which supply the excess current taken on either side of the line, thus maintaining a balanced condition on the system. In the Palace Theater (127 North Clark Street) there is a bank of Cutler-Hammer dimmers and a number of standard Cutler-Hammer controllers are used in connection with the motors operating the ventilating fans and house pumps. SPOT LIGHT DIMMER. BANK OF DIMMERS INSTALLED IN CHIGAGOS AUDITORIUM BEHIND_THE SCENES AT THE AUDITORIUM 37 CUTLER-HAMMER CONTROL IN: CHICAGO The Alhambra Hippodrome (1920 South State St.) in addition to Cutler-Hammer dimmers has a rope operated electric curtain hoist, the Cutler-Hammer apparatus used in connection with this device being similar to a small elevator controller. In this theater there are also a number of pumps operated by alter- nating current motors and controlled by Cutler- Hammer self-starters of the Bulletin 9610 type. The Englewood Theater (63rd and Halsted St.) has not yet been opened to the public but will have when completed an up-to-date dimmer equipment consisting of twenty-two double plates of the new “‘Simplicity” type, designed for use with tungsten lamps. Reference has already been made to the dimmers installed in the Auditorium—the home of Grand Opera in Chicago. An interesting feature of this bank are several auxiliary plates connected to the stage pockets, the function of these plates being to vary the resistance according to the load on the pockets. This is accom- plished by means of a single blade knife-switch with four clips. When the load on the stage pockets is light only one dimmer plate is used, the other being cut into circuit as the load on the pockets increases and more resistance is required to secure the dimming effect desired. The various plates are cut in and out of circuit by merely engaging or disengaging the knife- switch above re ferred to with the clips connected to the various plates. This simple arrangement fills a long felt want of the stage electrician. _ A complete list of Chicago theaters in which Cutler- Hammer dimmers are used would include all except three or four. The following are numbered among the wise ones, and even then the list is not complete: Academy of Empress Majestic Music Folly Marlowe Alhambra Fine Arts McVicker’s Auditorium Garrick Olympic Bijou German Palace Blackstone Haymarket Plaza Casino Illinois Power's College Imperial Princess Colonial Indiana Star and Garter Criterion La Salle Studebaker Crown Little Theater Willard Empire Lyric Ziegfeld COLONIAL THEATER This stately play-house, located on Randolph St. between State and Dearborn is known as the ‘‘Theater Beautiful’? on account of its impressive facade and the magnificent decorations in the lobby and auditorium. 39 CUTLER-HAMMER CONTROL IN) CHICAGO DEPARTMENT STORES The stranger in Chicago, endeavoring to get his bearings by means of the street signs, soon notes that the names of the streets are prefixed with the letters N.S. E. or W. These abbreviations stand for North, South, East and West. South State St., as soon as it crosses Madison St., becomes North State St.; and East Madison St., as soon as it crosses State St., becomes West Madison St. In other words, the prefix “N” or “S” is simply an easy way of saying North or South of Madison St. and the prefix “E” or “W” means merely East or West of State St. State St. which runs north. and south is the dividing line for throughfares which, like Madison St., run east and west; and Madison St. is the dividing line for streets that run parallel with State St. State St. and Madison St. are the official dividing lines, but the older divisions of the city into “North Side’, “South Side”, ‘‘West Side” and ‘The Loop” still survive in popular usage. Tip a letter T over on its side, thus....-....and let this represent the Chicago river with its north and south branches. The JUNCTION OF STATE AND MADISON STS.

The Loop District is the heart of Chicago and State St. is the heart of the Loop. On this throughfare, within the space of a few blocks will be found nearly all of the city’s great department stores, while crowded in between the larger stores, or overflowing into the adjacent cross streets, are scores of interesting shops in whose windows are displayed every conceivable article likely to tempt the purse of the passer-by. At the junction of State and Madison Sts. three of the four corners are occupied by huge department stores—Carson Pirie Scott, Mandel Bros. and the Boston Store. Walking south one comes within a few minutes to The Fair, Rothschild’s and Siegel Cooper’s, each occupying an entire city block, while two minutes walk in the opposite direction brings one to the famous Marshall Field store which covers two entire blocks. Other stores of equal interest, though not as large as those mentioned, will be found on State St. within a few blocks north or south of Madison St. In this paradise of the shopper will also be found— not displayed in the windows or show cases but attend- ing strictly to business in the basement or sub-basement *—a multitude of Cutler-Hammer controllers, prin- cipally Bulletin 3250 speed regulators, used in connec- tion with ventilating fans, and Bulletin 6140 and 6160 self-starters controlling the house pumps. In practically all of the large department stores will also be found carrier systems of the pnuematic tube type, governed by automatic controllers which vary the speed of the motor according to the number of carriers passing through the tubes at any given time. These controllers are similar to the one already de- scribed in connection with the Peoples Gas Building and illustrated on page 10 of this booklet. The great men’s furnishing store known as “The Hub” is equipped throughout (with the exception of the elevator motors) with Cutler-Hammer control, the ventilating fan motors being controlled by Bulletin 2245 compound speed regulators and the motors driving the house pumps by Bulletin 6141 self-starters. Various other machines, such as small drinking water pumps, refrigerating pumps, etc. are driven by motors controlled by Cutler-Hammer Bulletin 2110 motor starters. In the basement of this building there is a 43 ~ CUTLER- IN CHICAGO large and very complete generating plant, Cutler- Hammer field regulators being used in connection with the generator fields. In the Hillman department store (State and Wash- ington Sts.) there is an interesting installation of Cutler-Hammer self-starters used in connection with the pumps supplying water to the hydraulic elevators. The self-starters are energized by pressure gauges which are so adjusted that on light demand only one pump will operate while, when occasion requires, two or three pumps will be cut into service, the starting and stopping of the pumps depending upon the pres- sure in the storage tanks. At Stevens & Co. (opposite Hillman’s); at the Siegel Cooper store (Congress and State Sts.); and at The Fair (Adams and State) other applications of Cutler- Hammer control will be found. The escalators, or moving stairways, at Siegel Cooper’s are controlled by Bulletin 2150 motor starters and are equipped with safety brakes of Cutler-Hammer design. CUTLER-HAMMER FIRE PUMP STARTER INSTALLED AT “THE FAIR” Patience and preparedness are the first requisites of a fire pump starter. It may be idle for years and then be called on to act at a moment’s notice.

OPVOIHO AO ZNO 45 CUTLER-HAMMER CONTROL IN CHICAGO MAIL ORDER HOUSES Chicago is the home of the mail order house, a busi- ness which in comparatively few years has grown from small beginnings to gigantic proportions, the annual sales of a single one of these establishments running from fifty to eighty-five million dollars. Montgomery Ward & Co. and Sears Roebuck & Co. are the acknowledged leaders of the mail order business and in both of these vast establishments Cutler- Hammer control is used, practically to the exclusion of all other types of controllers. Visitors are welcomed at both establishments and will find so much of interest in connection with the expeditious handling of the vast number of mail orders, that the short trip necessary to reach either place is well worth taking. The Montgomery Ward plant is north of the river at Chicago Avenue and Larrabee St. and is easily reached by the Larrabee Street surface cars from the Clark and Washington St. corner of the City Hall. The Sears Roebuck establishment is west of the river, at Homan Avenue and Harvard St. near Douglas Park, and is reached by taking a Twelfth Street car at the Adams and Dearborn St. corner of the Post Office. The Sears Roebuck plant is practically a city in itself. It maintains its own paid fire department, police, hospital, restaurants, etc. The power plant here is one of the most complete private plants in existence. Some idea of the business transacted is indicated by the fact that it requires 500 girls to type out the orders received, that the mailing list contains nearly five million names and that postage stamps are purchased in $100,000 lots. The great general catalogs, and numerous special catalogs, issued by the great mail order houses neces- sitate the maintenance of complete printing plants, and at both the Montgomery Ward and Sears Roebuck establishments Cutler-Hammer control is used on the presses, trimmers, folders, binders and belt conveyors, which deliver the completed catalog to the mailing room. Some idea of the efficiency of the printing plant may be obtained from records kept by Sears Roebuck which show that catalogs have been printed, bound and delivered to the mailing room at the rate of one com- plete catalog per second. SHEARS ROEBUCK & CO. Homan Ave. and Harvard St. near Douglas Park. A FEW OF THE CUTLER-HAMMER CONTROLLERS IN THE SEARS ROEBUCK PLANT This battery of twelve Kohler System—Type NRF—controllers are used in connection with the single deck web magazine presses that print the great Sears Roebuck mail order catalog. CUTLER-HAMMER CONTROL | IN CHICAGO Motor drive is used throughout the Sears Roebuck plant wherever possible and aside from the large number used in the printing department there are over 450 additional motors all equipped with Cutler- Hammer control. Even this does not take into account motors of less than one horsepower, hundreds of which are used in connection with small labor saving devices throughout the plant. A recent addition to the Sears Roebuck business is a complete wall paper factory in which are installed some fifty machines with individual motor drive. The controls used with these machines are Cutler-Hammer Universal Compound Starting Panels slightly modified from the standard Bulletin 2245 construction. Another interesting application of Cutler-Hammer apparatus at the Sears Roebuck plant are two valve controllers of the remote control type, these being used to open and close valves in the water system. Motors of two horsepower capacity are installed in connection with the controllers about half a mile from the power house. Valves are opened and closed from the power house by merely opening or closing the circuit to the solenoid of the valve controller.

KOHLER SYSTEM CONTROLLER TRIBUNE BUILDING Madison and Dearborn Sts. PUSH BUTTON STATION HEARST BUILDING, Madison and Market Sts. The Kohler System type of Cutler-Hammer controller, illustrated in upper right hand corner, is used, with few exceptions, by all the large newspapers of the country. 49 CUTLER-HAMMER CONTROL IN CHICAGO NEWSPAPERS Chicago is proud of its newspapers and its news- paper men, among whom have been numbered Eugene Field, author of “Little Boy Blue” and other well- known poems; George Ade, author of “Fables in Slang”’ and Peter F. Dunne, the creator of the inimitable “Mr. Dooley”. The Cutler-Hammer Mfg. Co. is proud of its con- trollers for newspaper presses. This line of controllers, comprising the well-known Kohler System of Push- Button Control has been installed, with few exceptions, by every important newspaper in the United States and Canada as well as by such representative foreign papers as the London Times, the Paris Matin, Cal- cutta Statesman, Melbourne Argus, La Prensa of Buenos Aires, and others. In the Kohler System of electrical control every movement of the largest press, or other motor driven machine, is dominated by a little push-button.

The controller proper is entirely automatic in its action. The push-buttons merely convey the signal to the controller, which executes the command. Pres- sure on one button signals “start”, and the controller sets the press in motion. Pressure on another button says “stop”, and the machinery which a few seconds before was operating at full speed comes quickly and quietly to rest. By means of The Kohler System the time required to bring the press, or other machine, from rest to full speed can be adjusted to suit the operator. The usual time is twenty seconds. While running at full speed, or any intermediate speed, the machine can be almost instantly stopped, the actual time required being merely the few seconds necessary to prevent stripping of gears. Starting, stopping and changes of speed are all accomplished without the slightest jerk or jar, reduc- ing wear and tear to a minimum. ‘The gradual start and graduated increases of speed prevent sudden rushes of current, economizing power and insuring the motor against damage due to careless operation. When dressing the press for a run the cylinders may be slowly revolved, brought to any desired position and stopped instantly. A movement of as little as one-eighth of an inch can be made. A threading speed of approximately ten revolutions per minute of the plate cylinders can be obtained, facilitating the passing of the web from point to point. While operating at full speed should the web break, or some other accident occur, any of the pressmen can instantly stop the press by pushing the “stop” button at the nearest control station. The first Kohler System controller was installed in the plant of the Chicago Daily News. In this same plant there is an interesting installation of Stone Magazine Reels (another Cutler-Hammer product) which enable fresh rolls of paper to be fed to the press without stopping the run. The press rooms of the Chicago Tribune and Chicago Evening Post are also equipped with Kohler System controllers, and in the Hearst Building—the home of the Chicago Examiner—there are a number of electric- ally heated matrix drying, tables of Cutler-Hammer manufacture.

These are Dearborn St. and the two narrow streets that flank it on either side—Federal St. and Plymouth Court. From Polk St., in front of the Dearborn Station, to Van Buren St., two blocks north, these three streets are lined on both sides with commercial printing and publishing plants and with the warehouses and stores of manufacturers and dealers in printers supplies. Tt is in Printers’ Row that Cutler-Hammer control dominates the field completely, for there is no industry that is so entirely of one mind regarding electric con- trollers as the disciples of Gutenberg. For years Cutler-Hammer controllers have been the standard of the printing trade, which is not to be wondered at when one considers that in the immense plant of Rand-MecNally & Co., there are several Cutler- Hammer motor starters, still on the job, that have seen more than eighteen years of service. In this plant all of the 55 flat bed and web presses are equipped with Cutler-Hammer controllers, prin- cipally Bulletin 4140 and 4240 controllers of the well- known Carpenter type. The platen presses, feeders, trimmers, stitchers and other machines—some 300 in all—are also Cutler-Hammer controlled.

(2501 South Dearborn St.) have 35 platen presses equipped with Cutler-Hammer Bulletin 3110 speed regulators and a number of Carpenter type controllers on the larger presses. Outside of the establishments on Printers Row, it is the same old story—wherever one smells printers’ ink in any part of Chicago Cutler-Hammer controllers of one type or another will be found. The Western Bank Note & Engraving Co. (118 East 20th St.) use Kohler type controllers. The Goes Lithographing Co. (175 West Jackson Boulevard) prefer Carpenter type. The Kehm, Fietsch & Miller Co. (430 West Erie St.) have both kinds. The American Colortype Co. (111 West Monroe St.) have an equipment consisting of 18 Kohler type and 32 Carpenter type controllers. R. J. Kittridge & Co. (Green and Superior Sts.) have 34 presses equipped with Carpenter type controllers. The Western News- paper Union (521 West Adams St.) use Carpenter type controllers exclusively on 35 presses and nearly a hundred Cutler-Hammer motor starters and speed regulators on their smaller machines. The W. F. Hall Co. (Superior and Kingsbury Sts.) pin their faith to Kohler type controllers, and have IN CHICAGO 44 of these installed on the walls of the press room, connected to push-button stations mounted on the frames of the presses. In this same plant there is an interesting piece of Cutler-Hammer apparatus—known as the Obert Detector. This is designed for use with web presses its function being to automatically stop the press should any imperfection be encountered in the web. Another particularly interesting installation is to be found at the plant of the Max Lau Colortype Co., con- sisting of a new type of Cutler-Hammer alternating current printing press controller. This is the first lot of alternating current controllers to be installed in a Chicago printing plant, direct current motors being used, as a rule, with printing machinery. A complete list of Chicago printing plants that use Cutler-Hammer controllers would be practically equivalent to a directory of the trade. If more names are wanted select them at random from the classified section of the Chicago Telephone Directory and nine out of ten names so selected will be users of Cutler- Hammer control. Five of the 44 Cutler-Hammer—Kohler Type—controllers installed in plant of the W. F. Hall Printing Co.; 466 West Superior St, “STATION RAILROADS There are six railroad stations in Chicago, all in the business center of the city. The location of these stations are shown on the map which will be found in the back of this booklet. In these stations a ma- jority of the controllers in- stalled are of Cutler-Ham- mer manufacture, the principal applications being in connection with motor driven pumps, ventilating fans, and mail conveyors. The classes of Cutler-Hammer control used are principally Bulletin 2110 and 2150 motor starters, Bulletin 3150 and 3250 speed regulators and self-starters of the Bulletin 6141 type. In connection with the electrically operated cancelling machines used in the railway mail service small speed regulators (Bulletin 8520) are employed. Installed along the right-of-way of the Lake Shore & Michigan Southern railroad are a number of Cutler-Hammer alternating current self-starters of the type listed in Bulletins 9600 and 9610. 57 CUTLER-HAMMER CONTROL IN CHICAGO These self-starters are used in connection with motor driven pumps for filling the locomotive water tanks and are left without supervision for considerable periods. The self-starters used on these installations are so arranged that should the fuse in one line blow, or one phase become de-energized, in any way, the self- starter will not operate to connect the motor across the line, thereby eliminating the possibility of the motor being burned out through being connected in only one phase a three-phase circuit. Practically all railroad lift or draw bridges are de- signed nowadays for electrical operation, provided they are to be erected at points where current is avail- able. An interesting installation of this kind may be seen just outside of the city limits of Chicago where the main line tracks of the Baltimore & Ohio railroad are carried across the Calumet river by the largest single leaf bridge in the world—a span of 235 feet. This bridge is operated by two 140 H. P., 3-phase, 60-cycle, 440 volt, slip-ring motors which are con- trolled by a Cutler-Hammer duplex drum controller of special design. oe!

Liberal transfer privileges are accorded passengers; so liberal, in fact, that it has been calcu- lated that by carefully planning one’s route it is pos- sible to ride twenty-five miles, or more, for a single five cent fare. The visitor to the city should bear in mind that cars always stop on the near side of street crossings. By remembering this, the annoyance of standing on the wrong corner and having the car whizz by without stopping will be avoided. No one, except a Chicago policeman, knows where the different cars go, hence the stranger within the gates will do well to seek information only from the man in uniform who will be found regulating the street traffic at all crowded crossings. The tedious delays that formerly occurred when cars crossed the river at Washington St. and La Salle St. on bridges and were obliged to wait while the bridge was TY MOTOR DRIVEN LATHES CONTROLLED BY CUTLER-HAMMER SELF-STARTERS West Side Shop of Chicago Railways Company.

A tunnel seems an unlikely place in which to en- counter a Cutler-Hammer controller, but look on page 63 and you will see an interesting picture of one which is installed in the Washington St. tunnel, and there is another like it in the La Salle St. tube. These con- trollers are automatically operated by float switches and their function is to keep the pump motor on the job when river water seeps into either tunnel. In the Market Street Building of the Chicago Railways Co. (324 South Market St.) there is installed a 100 H. P., 600 volt, fire pump starter. It will be seen from this that Cutler- Hammer control is considered equally efficacious as a protection against damage by either fire or water. The elevators in the Market Street Building are equipped with Cutler-Hammer elevator controllers— Schureman type—and in the West Side Shops of the Chicago Railways Co. there are approximately 150 Schureman type self-starters, ranging in size from 2 H. P. to 35 H. P. Some of these are illustrated on pages 60 and 61. WOOD WORKING SHOP Chicago Railways Company CUTLER-HAMMER 50 H. P.

Northwest Station Commonwealth Edison Co. 65 CUTLER-HAMMER CONTROL IN CHICAGO CENTRAL STATIONS Operating in and around Chicago are the Common- wealth Edison Co., the Public Service Company and the Cosmopolitan Electric Co. Of these the Common- wealth Company supplies the greater amount of current, having three immense power plants and numerous sub-stations within the city limits. The power plants are known as the Fisk Street Station, the Quarry Street Station and the Northwest Station, the last named being the latest and largest of the three. In all of these power plants Cutler-Hammer appar- atus is used for controlling the motors operating ventilating fans and pumps, and scattered throughout the various stations will be found a miscellaneous lot of Cutler-Hammer starters and controllers used in connection with such machines as are accessory to the large power units. An interesting installation of Cutler-Hammer control in the Northwest Station of the Commonwealth Edison Co. consists of an electrically operated fire pump which is started and stopped automatically by a Cutler- Hammer fire pump starter. The pump installed in this plant is by far the largest in the city devoted exclusively to this class of service. On page 67 there is an illustration of the fire pump starter above referred to. In the lower right hand corner will be noted the double-throw 600-ampere switch, connecting the panel to either of two sources of supply. At the top is seen the primary overload circuit-breaker, flanked by an indicating ammeter and voltmeter. The signal lamps indicate when energy is available and when the motor is running. The ten cam-operated crank switches at the center of the panel are closed in succession by the two large alternating- current solenoids, acting through racks and pinions. These solenoids are in turn controlled by the pressure diaphragm in the lower left hand corner. When the pressure falls to 135 lbs. an auxiliary circuit is closed, energizing the clapper switch at the right, which in turn completes the contact to the solenoids. The three left hand switches of the crank group are in the primary circuit and close quickly through lost-motion links. The carbon blocks with which they are fitted take all arcing and can easily be renewed. The seven switches at the right are secondary contacts cutting out the secondary starting resistance one step at a time, mean- while keeping all three phases balanced.

The Quarry Street Station is on the south bank of the river opposite the Fisk Street Station. 67 CUTLER-HAMMER CONTROL IN CHICAGO ba secondary running switches are shown at the extreme right. If desired, the panel can be operated manually by simply lifting the hand lever shown. ‘The lever is then held in the running position by means of a latch rod extending through the panel. This latch rod is arranged with a no-voltage relay, releasing the hand lever auto- matically upon failure of the voltage. The panel measures 5x5 feet, and the resistor elements are mounted behind the two-inch slab of oiled slate. The motor with which this starter is used is a 225 Hes 220 volt, 3-phase, 60-cycle, slip-ring motor and the pump has a capacity of 2000 gallons of water per minute at a pressure of 150 pounds per square inch. There is an equipment similar to that above des- cribed in the Fisk Street Station of the Commonwealth Edison Co., this installation, however, being designed for use with a 225 H. P., 220 volt, direct current motor. The elevated railroads of Chicago buy the greater part of their power from the Commonwealth Edison Co. but at 39th and State Sts. there is a power house which supplies a portion of the current used by the South Side Elevated Railway Co. In this plant Cutler-Hammer control is used in connection with the coal handling equipment. CUTLER-HAMMER FIRE PUMP STARTER Installed in the Northwest Station of the Commonwealth Edison Co. POWER HOUSE ON THE CHICAGO SANITARY AND SHIP CANAL NEAR LOCKPORT, ILLINOIS. DAM AND LOCKS AT POWER HOUSE In connection with the lock there are installed four valve motors controlled by Cutler-Hammer valve controllers as are also the four gate motors of the lock. 69 CUTLER-HAMMER CONTROL IN CHICAGO DRAINAGE CANAL Near Lockport, Illinois, about thirty miles from Chicago, is a hydro-electric development of much interest to engineers. This is the power house and dam erected by the Sanitary District of Chicago for the purpose of utilizing the water power of the famous Drainage Canal, which extends from the south branch of the Chicago: river at Robey St. to a point between Lockport and Joliet where it empties into the Desplaines river, the waters of the canal finally reaching the Gulf of Mexico by way of the Illinois river and the Missis- sippi. This canal forms an important Jink in the proposed Lakes-to-the-Gulf Waterway and in the portion of the canal already completed locks and a turning basin at Lockport are provided. A narrow strip of land on each side of the canal is under the jurisdiction of the trustees of the Sanitary District of Chicago, corresponding to the zone con- trolled by the national government at Panama. The power house and dam may be reached by taking an Archer Ave. car to the terminus and there transferring to the Joliet electric line, or by Chicago & Alton trains from the Union Depot. The power house is 385 feet long, 70 feet wide and 47 feet high. The channel retaining walls are 40 feet high and bring the water level nearly to the top of the building on the receiving side, the turbines being served by a fall of about 34 feet. The turbines are located in chambers at the floor level and discharge through auxiliary chambers to the tail race. ANOTHER VIEW OF THE POWER HOUSE AND DAM.

CUTLER-HAMMER CONTROL IN CHICAGO The power plant is designed for housing eight water wheel units of 6,000 H. P. each and three of 600 JB ls lees these furnishing power to drive eight generators of 4,000 K. W. each and three, 350 K. W., exciter units. The current, generated at 6,600 volts, is raised to 44,000 volts by transformers and is transmitted over heavy aluminum wires to Chicago where, after being stepped down to the proper voltage, it is used for light- ing the city’s streets and public buildings. The main transmission line is thirty miles long. The steel masts, of bridge construction, are sixty feet high and weigh 4,000 pounds. There are at present two 3-phase circuits and one ground wire carried on the peaks of the poles, the wires being spaced six feet apart. The large generator units and exciter units in the power house are controlled by Cutler-Hammer motor- driven field regulators. In connection with the locks there are installed four valve motors the operation of which is governed by Cutler-Hammer valve controllers. There are also four gate motors at the locks, these being operated by Cutler-Hammer controllers of the reversing magnetic switch type.

A few years ago the town site was a barren waste of sand, possessing, for the ordinary eye, not one attractive feature. But there are eyes that can look into the future and to such eyes this desert on the southern shore of Lake Michigan possessed one thing that outweighed all other considerations—namely, its location. ‘To the west of Gary lie the rich iron mines of the Lake Superior region; to the east the coal fields of Pennsylvania, and in both directions stretch the waters of the Great Lakes, providing cheap trans- portation. It is said that over one hundred million dollars has been spent by the United States Steel Corporation in converting eleven thousand acres of sand dunes into a busy town, from the midst of which rise the huge build- ings that house the largest steel plant in the United States.

In this plant more than a hundred Cutler-Hammer disc brakes are used in connection with various motors, and outside of the buildings one finds Cutler-Hammer controllers on the coal bridge and Cutler-Hammer lift- ing magnets on the cranes used for handling pig iron and scrap. There are now in use here sixteen Cutler- Hammer magnets, ranging in size from the 36-inch and 42-inch magnets used for “skull-cracker” work to full grown 62-inch magnets that pick up 3,000 pounds of pig iron, or more, at a single lift. Cutler-Hammer control is used by the American Sheet & Tin Plate Co., which is also located at Gary, SALVAGING KEGS OF NAILS WITH A CUTLER-HAMMER MAGNET. 76 CUTLER-HAMMER CONTROL IN CHICAGO AIR COMPRESSOR AND CONTROLLER Francis Nygren Foundry. and at Indiana Harbor hundreds of controllers of the same kind are installed in the plant of the Inland Steel Co. It was at Indiana Harbor that two 62-inch Cutler- Hammer lifting magnets established a new record for unloading pig iron. When ore boats are unloaded by manual labor it usually requires several days to com- plete the work, but with the aid of a pair of magnets four million pounds of pig iron were unloaded in ten and a half hours, the average lift per magnet being close upon 3,500 pounds. In Chicago and South Chicago Cutler-Hammer con- trollers, and in some cases lifting magnets as well, are’ used by such companies as the Iroquois Furnace Co., the Edgar Allen American Manganese Steel Co., The Railway Steel Spring Co. the Marks Mfg. Co. (at Evanston) Republic Iron & Steel Co., Wisconsin Steel Co., and others. 77 CUTLER-HAMMER CONTROL - IN CHICAGO MISCELLANEOUS Michigan Boulevard below Twelfth St. is known as Automobile Row. Here, crowding both sides of the street, are the show rooms of all the leading manufac- turers of motor cars, garages, and establishments that make a specialty of automobile supplies and repairs. At all hours of the day the roadway is thronged with a continuous procession of cars, this lively stretch of Michigan Boulevard being, in fact, an all-the-year- round automobile show. One of the busiest shops in the Cutler-Hammer plant is that devoted to the manufacture of a battery switch for automobiles. This little switch is admirably adapted for the service for which it is designed and has been adopted as part of their standard equipment by many of the leading automobile manufacturers. The increasing use of electric vehicles has led to numerous installations of battery charging rheostats in Chicago and a goodly proportion of these bear the Cutler-Hammer name plate. The installation illus- trated on this page is that of the American Express Co. i V 7 — CUTLER-HAMMER BATTERY CHARGING RHEOSTATS Installed in the American Express Co.’s Garage. AUTOMOBILE ROW This is the name given to Michigan Boulevard south of Twelfth St. Automobile show rooms, garages and dealers in automobile supplies line both sides of the street. 79 CUTLER-HAMMER CONTROL IN CHICAGO and consists of 42 charging rheostats. The Ward- Corby Baking Co. has an equipment consisting of 40 rheostats, and many smaller installations are to be found in public and private garages. In the Ward- Corby bakery the dough-mixers and other motor driven machines are controlled by Cutler-Hammer motor starters and speed regulators. In one brewery in Chicago, that of the Peter Schoen- hofen Brewing Co., (526 West 18th St.) there is a total of 150 motors ranging from one-half to 45 H. P. These include the motors for a score of pumps of various kinds, barrels conveyors, box conveyors, malt conveyors, bucket conveyors for coal and ashes, and dozens of smaller machines such as bottle washers, bottle fillers, pasturizers, labeling machines, etc. But in spite of the great variety of machines employed only one type of control is used—Cutler-Hammer. Similar installations will be found in other large breweries in Chicago, such for instance as The Keeley Brewing Co., the McAvoy Brewing Co., the Wacker & Birk Brewing & Malting Co., the Conrad Seipp Brewing Co., the Fortune Bros. Brewing Co., and the Standard Brewery. Alternating current motors are used to drive the various machines used in the manufacture of the famous Spearmint Chewing Gum and at the plant of the Wm. Wrigley Jr. Co., (727 West Van Buren St.) will be found some twenty star-delta switches—Cutler- Hammer Bulletin 9150. There is a similar installation of star-delta switches at the factory of the Imperial Brass Co., 524 South Centre Ave. Cutler-Hammer fire pump starters are to be found in almost all modern buildings in Chicago, these being of a type especially designed to meet the rigid municipal regulations regarding fire protection. The 150 H. P., 220 volt fire pump starter in the clothing factory of Hart Schaffner & Marx (36 South Franklin St.) is typical of this type of apparatus. Pressure is con- stantly maintained on the sprinkler system by the controller, which automatically starts the motor when- ever the pressure drops to 140 pounds. The degree of perfection attained in this installation may be judged by the fact that the motor operates only about once every ten days and in a few minutes restores full pres- sure to the tank, whereupon it is automatically stopped by the controller and remains at rest until the pressure again drops to 140 pounds. ' aR eeaey CHICAGO'S FAMOUS STOCK YARDS No book on Chicago would be complete without some reference to the famous Stock Yards. Here, as elsewhere throughout the city Cutler-Hammer controllers are in evidence. In one plant alone, that of Armour & Co., there are 450 motors, more than 400 of which are equipped with Cutler-Hammer control.
