HE United States Electric Lighting Company was organized in 1878, and was T among the first in this country to undertake the development and introduc- tion of the Electric Light for purposes of practical illumination. The Weston Electric Light Company, which is now owned by this company and under the same management, was organized a year earlier, and several of the inventors and electricians who are now employed by the United States Company, and whose inventions and patents have become its property, had done a large amount of valu- able preliminary work long before the organization of either company. W'ithin the past few years lighting by electricity has grown from a doubtful experi- ment into an established system of illumination, in large and rapidly increasing practical use ; and in the work by which this result has been accomplished this company has taken an active part. Having abundant capital, it has been able to employ inventors and electricians of the highest ability, to furnish them with extraor- dinary facilities for experimental work and investigation, to secure the control of important inventions made by other inventors, and to provide extensive manufactur- ing facilities for constructing its apparatus in the most perfect and economical manner. Mr. Weston, Mr. Maxi.M, and Professor P'armer are the principal electricians of the company, and the apparatus which it manufactures has, for the most part, been invented by them. Other inventors and electricians, of well-recognized ability, have also been employed, and valuable outstanding patents have been purchased from time to time. The ablest counsel and experts in the country have been employed by the Com- pany to take charge of all patent matters relating to its business, and great pains have been taken, not only to thoroughly protect by patents the work of its own inventors, but to carefully avoid infringement of the rights of others. The company noiv ozons or controls more than a hundred atid fifty patents, and is constantly adding to this number as its inventors make further imijrovements. These 4 THE UNITED STATES ELECTRIC LIGHTING CO. relate chiefly to the electric light, electro-plating, and electrical transmission of power, and cover the most important contributions made to the progress of these applications of electricit}’ during the past twenty years. As is well known, there are two principal systems of lighting by electricity — the voltaic arc system and the incandescent system. While other companies have given their exclusive attention to one or the other of these two systems, this company has undertaken the development of both, believing that the greatest advantages would be secured by working the two together. The arc light is especially adapted for light- ing large spaces where a great amount of light is required, but is not suitable for general interior illumination. The incandescent light is especially adapted for interior lighting, as it admits of more convenient division and distribution; but it is greatly inferior to the arc light in economy for lighti ng large spaces. In many cases the best results can be obtained only b}’ a combination of the two systems. The W eston arc system and the incandescent system, comprising the Maxim incan- descent lamp and the W'eston machine, which have been adopted by the company, have long since passed the experimental stage, and are in extensive practical use both in this country and abroad. They have received the highest commendations, both from eminent scientific men and from practical users, and the large and rapidly increasing demand for apparatus for lighting by these systems is the most satisfactory evidence of the estimation in which they are held by the public. It has been tho policy of the compan\' to spare no trouble or expense in securing the best forms of dynamo-machines, electric lamps, and other apparatus, and in per- fecting them in all their details. Very important improvements have recently been made, bj' which greater simplicity of construction, and higher efficiency and reliabil- ity in operation have been secured. As such apparatus has to be used, for the most part, by persons having little or no practical knowledge of electricity, it has been the aim of the company to make its apparatus strong and simple in construction, and self- regulating, as far as possible, in operation, so that it can be operated without difficulty by any person with the most ordinary knowledge of mechanics. In this respect, as well as in efficiency, economy, and reliability in operation, and in the color and steadi- ness of the light produced, these systems of lighting are confidently believed to be far superior to any other now before the public. In addition to its principal business of manufacturing electric lighting apparatus, the company does a very large business in electro-depositing apparatus. This branch of the business was established by the W'eston Company, and has been very suc- cessful. The W'eston electro-depositing machine has gone more largel)'^ into use than any other in the market, and has in all cases given the most satisfactory results. hdectric motors and various forms of special apparatus, and instruments for use with large currents, are also manufactured by the company. Since its acquisition of the W'eston factory at Newark, N. J., the company has concentrated its manufacturing business there. The capacity of this factory has been more than cpiadrupled during the past year, and it has been fitted up in the most thorough manner with the best modern tools and machinery. It is one of the largest I nctory of llie L iiited States Klectric I.igliling Co., Newark, THE UNITED STATES ELECTRIC LIGHIING CO. 6 THE UNITED STATES ELECTRIC LIGHTING CO. and best appointed factories in the country devoted to electrical work. A large force of skilled workmen is employed, many of whom have been with the company for a long time, and have been thoroughly trained in the manufacture of its apparatus. Only the best materials are used, and great precautions are taken to insure the most accurate mechanical and electrical work. Various subsidiary or local companies have been organized in different parts of the country, under licenses from this company, and all are in successful operation. Among these are the New England Weston Electric Light Company, of Boston, Mass.; The Rhode Island Electric Light Company, of Providence, R. I.; The Con- necticut P'lectric Light Company, of New Haven, Conn.; The United States Illumi- nating Company, of New- York City; The Newark Electric Light and Power Company, of Newark, N. J.; The Maxim Pdectric Light and Power Company, of Philadelphia; The Rochester Electric Light Company, of Rochester, N. Y. ; The United States Electric Illuminating Company, of Charleston, S. C. ; The Citizens’ Electric Light Company, of Toledo, O. ; The Cincinnati Electric Light Company ; The Swift Elec- tric Light Company, of East Saginaw, Mich.; The St. Paul Electric Light and Power Company, of St. Paul, Minn.; The Racine Electric Light and Power Company, of Racine, Wis., and many others. These companies are using and introducing the apparatus manufactured by the -parent company, and many of them are doing a large business in furnishing lights on rental from central stations. ADVANTAGES OF THE ARC SYSTEM. ’"’'IIE superiority of the Arc light over all other systems of illumination for use in 1 . places where a large amount of light is required, has been thoroughly demon- strated by experience, and is now generally well recognized. Fu'st. It is the cheapest artificial light known. This has been shown both by scientific tests and by the experience of practical users given in the testimonials which we publish farther on. Second. It is the safest light known, being wholly free from all danger of explosion, leakage, use of matches, etc., incident to gas, oil, and other systems of lighting. The underwriters throughout the country have made a careful examination of the subject, and have in all cases concluded that lighting by this system is free from danger, when the apparatus is properly constructed and erected. The New York Board of P'ire Underwriters has adopted regulations for the erection of plants, with which we care- fully comply. Third. It is a pure zuhite light, in character closely resembling sunlight. All colors appear precisely the same by this light as by daylight. This is a point of great THE UNITED STATES ELECTRIC LIGHTING CO. 7 importance where artificial light is used in factories, stores, dye-houses, and other places in which it is desirable to distinguish colors. Fourth. It is an agreeable and zuholesome light. A single gas-burner consumes as much oxygen as is required by five or six persons for respiration, and the noxious gases and great amount of heat evolved by oil and gas lights are disagreeable and deleterious to health. The electric light does not depend on combustion for its illuminating effects, and, accordingly, does not vitiate the air, and the amount of heat produced is extremely small. The light produced by the Weston arc system is remarkably steady, free from flickering, and is soft and agreeable to the eye. Fifth. The iuimense quantity of light which can readily be produced by the arc system renders it possible to obtain a perfect general illumination of a workshop, store, or other large space which is not economically attainable by any other system of lighting. This is of great importance in manufacturing establishments where night work is necessary, as the work can be carried on with almost as much facility by the electric light as by daylight. The arc system is especially adapted for lighting streets, public squares, parks, docks, and other out-of-door places, and for lighting large interior spaces, such as factories, mills, foundries, mines, warehouses, stores, public halls, railway stations, hotel offices, tunnels, and the like. Although it is not suitable for general interior illumination where only a comparatively small amount of light is required, the arc light is, within its proper field, far superior to all its competitors. With improve- ments in apparatus the field of the arc light is constantly expanding. The steady and reliable Weston arc lights are now in common use both in this country and abroad, in places where the flickering and uncertain arc lights of two or three years ago would not be tolerated, and are giving the most satisfactory results. THE WESTON ARC SYSTEM. T he Weston Arc System differs from other arc systems now in use, not only in the construction of the apparatus, but in the character of the current used and in the quality of the light produced. The lamps are adjusted to work with a shorter arc or separation between the carbon points, and the machines are constructed to generate a continuous current of low'er electro-motive force and greater quantity than in other systems. This not only obviates the danger of accident to persons using the appa- ratus, but renders the light produced of better quality and of greater quantity for a given expenditure of power. While numerous fatal accidents have occurred from the use of machines producing an intermittent or pulsating current of very high electro- motive force, 710 person has ever beeii m any way injured by the curroit f 7 - 077 i a Weston Machific. This remarkaMe immunity from accident is not by any means fortuitous. s THE UNITED STATES ELECTRIC LIGHTING CO. but is due to the construction of the apparatus and the character of the current used in tlie Weston system. The electro-motive force of the current, even with a very large number of lights in circuit, is too low to permit it to injuriously affect any per- son accidentally coming into contact with the conductors, and the current is continu- ous and entirely free from the pulsations to which the disastrous effects of the current upon the person injured have been largely due in such accidents as have occurred with other systems. With our larger machines we have adopted additional precau- tions, in thoroughly insulating all parts which have to be handled, and we believe that the entire safet}' of the Weston system will commend itself as by no means an unim- portant advantage. The flickering due to slight impurities in the carbons, which is so noticeable in long arc systems, is almost entirely obviated by using a short arc, and the color and quality of the light are greatly improved. The light is free from the excess of blue and violet rays so noticeable in most other systems, and which are so disagreeable and tr)-ing to the eyes, and the light is much more diffusive. The extreme delicacy of the feeding mechanism in the lamps, and the purity and uniformity of the Weston carbons, render the light remarkably steady, and the extra- ordinary efficiency of the machine secures the highest degree of economy. In addition to the machine and the lamps, the Weston arc system comprises various auxiliary or supplementary devices, such as regulators, indicators, cut-off boxes, switches, and fixtures, which add greatly to its convenience and reliability. THE WESTON DYNAMO-ELECTRIC MACHINE. mechanical and electrical details of the Weston dynamo-electric machine have J- been very carefully studied, and we believe it is unrivalled in efficiency, simplicity of construction, strength, durability, the case with zuhich it can be repaired in case of accidents, and excellence of zvorkmanship and materials. We in\'ite a critical examina- tion and comparison of this machine with any other, by skilled mechanics, or other persons conversant with the requirements of the art. It is beyond doubt the most symmetrical, substantial, and efficient machine in the market. The general construction of this machine is shown by the cut on the opposite page. The field magnets are placed in a horizontal position on each side of the armature, and their cores, pole-pieces and yoke-plates form a rectangle of cast-iron which serves as the frame of the machine. The yoke-plates at each end are carried down so as to form feet, which support the machine, and the supports for the arma- ture bearings are cast in one piece with the frame. The armature is cj’lindrical in form, and its iron core is built up of a series of iron disks placed side by side, but separated slightly from each other. This construction is shown in the cuts on page lO, in which also a single disk is shown. In this way the armature core is split up into a large number of separate sections insulated from each other by air spaces at every point (except very near the center). riie W'csion i )ynanio- I'^lcLti ic Macliiuc. 10 THE UNITED STATES ELECTRIC LIGHTING CO. By this peculiar construction of the armature, induced currents in the core are almost entirely prevented, and the loss of energy and consequent injurious heating of the core, so common in other dynamo-electric machines, is entirely avoided. In order to still further increase the efficiency of the machine, the armature is con- structed to operate as a fan or blower to produce a rapid circulation of air from the center to the periphery, through the sectional core, thus cooling the conductors on the armature, and keeping their resistance much lower than would be the case if this method of construction were not used. The coils are wound lengthwise of the arma- ture, and connected to the commutator at the end. The complete armature is shown in the cut below. By the peculiar winding of the coils on the armature, and .\rmature Core and Single Disc. Armature Complete. their connection with the commutator, the highest possible efficiency is secured, and the coils arc so perfectly balanced electrically that the spark on the commutator is hardly appreciable. Owing to the rigidity of the bearings and general excellence of design and work- manship, the armature can be revolved between the poles with an extremely slight clearance — a condition very favorable to high efficiency. The coils exciting the field magnets, instead of being placed in the main circuit in the usual way, arc placed in a branch or derived circuit of high resistance, and only a THE UNITED STATES ELECTRIC LIGHTING CO. 11 running very small fraction of tlie entire current passes tlirough tliem. Great advantaf^es are secured by this arrangement of tlie field coils. Less current energy is expendetl in sustaining the field, the current is more steady, and the machine more uniform in its operation; it is impossible to injure the armature by short circuiting the main cir- cuit, and a perfect and extremely economical system, of regulation can readily be applied. The regulator is shown in the cut on this page. It consists of a rheostat or adjustable resistance placed in the field circuit. This is inclosed in a box, and is operated by a handle outside, as shown in the cut. It may be placed in any con- venient position, either near the machine or at a considerable distance away. By simply turning the handle of the regulator, the machine may be adjusted to run any number of lights from one up to the full number it is capable of running. All other methods of regulation which have been applied to machines for arc lights have proved so objectionable in practice that they have been but little used. They have so disturbed the electrical balance of the machine as to produce a very injurious spark on the commu- tator with less than the full complement of lights in circuit, and the consumption of power has not been reduced at all in proportion to the number of lights cut out. With this method of regulation, however, the operation of the machine is as perfect with one light in circuit as wfith the full number, and the con- sumption of pow'er is at all times very nearly pro- portional to the number of lights in use. A device for accomplishing the same result automatically is now' in the works. The efficiency of this machine is extremely high. Recent tests have shown that over NINETY PER CENT, of the power applied at the driving-pulley is available as useful current in the working or lamp circuit, the market approaches this degree of efficiency. We make machines of this type of various sizes, for running from one to thirty arc lamps in the same circuit. Machines of larger sizes are in course of construc- tion, and will soon be ready. Attached to all our derived circuit machines is a device for preventing shocks and sparks while establishing or breaking connection between the machine and the field conductors. This device consists of a coil of high resistance in the field circuit, in combination with a switch, w'hich, when closed, cuts out the resistance coil. On opening the switch when the machine is in operation, the current is reduced to such an extent that the line connection may be broken without the least danger to the machine or to the person operating it.

Some of these are shown in the cuts on this and the following page. In all these the lower carbon is fi.xcd, and the upper carbon only is fed downward.

In all these lamps the frame is made of brass and iron, and all the electrical connections are 14 THE UNITED STATES ELECTRIC LIGHTING CO. placed inside of the frame and thoroughly insulated from it. On page 13, at the left, is shown an ornamental lamp for use in stores, hotels, offices, and like places. On the same page at the right is shown an inclosed-frame lamp especially adapted for out-of-door use. The globe is suspended from the casing containing the feeding mechanism by means of a tubular support which incloses the upper carbon and the electrical connections. By this construction all the working parts of the lamp are entirely in- closed and thoroughly protected from the weather, the arc also is completely inclosed, and more perfect insulation is secured, both of the electrical connections and of the carbons themselves, than is attainable by any other con- struction. The same style of frame may be used for duplex lamps. These lamps are especially de- signed for series lamps, as the feeding mechanism of each lamp is entirely independent, in its op- eration, of that of other lamps in the same circuit. They work equally well, however, as single lamps. For use with reflectors in steam- boat and head-light projectors and the like, we make a focusing lamp shown in the cut on this page. In this lamp both carbons are mov- able, and their relative rates of movement are so adjusted that the arc is maintained at a fixed point. The feeding mechanism of the Weston lamp is simple in construc- tion, and extremely sensitive and certain in operation. It maintains the proper adjustment of the car- bon points with almost mathe- matical precision, and responds immediately to the slightest fluctuations in the strength of the Focusing Lamp. Current. THE UNITED STATES ELECTRIC LIGHTING CO. 1 .') A I’ TO M AT I C C U T - O L 'r. T'l'^mCN lamps are run in scries, two different forms of automatic cut-out are ' ' used with each lamp for shunting the lamp out of circuit, in case the feed- ing mechanism should for any reason fail to act. One of these consists of an electro-magnet placed in the circuit of each lamp, and so arranged as to close a shunt about the lamp whenever the circuit through it is for any reason interrupted, thus preventing the extinguishing of the other lamps in the series. The other form of automatic cut-out (shown in the cut on this page) is especially designed to prevent any injurious elonga- tion of the arc through failure of the feeding mechan- ism to work properly. It consists of a spring switch normally held open by a small plug, made of an alloy which fuses at a very low temperature. This plug is placed near the upper carbon, but at a sufficient dis- tance above the arc to prevent its melting when the arc is of normal length. If, however, the feedin mechanism fails act, the arc becomes elongated as the car- bons burn away, and the great increase of heat melts the fusible plug, allowing the switch to close and cut the lamp out of circuit. The cut-out may be again adjusted by opening the switch and inserting another fusible plug. A top view of the fusible plug, and the jaws holding it, is given in the lower part of the cut, at the right. This device has been found far more effective and reliable in operation than any other form of cut-out now in use, but, owing to the simplicity and certainty of action of the Weston feeding mechanism, it is rarely brought into action in practice. to to Time-meter.

It is fitted with a powerful focusing lamp, and projects a very intense beam of light for a long distance. This has been in use for a long time on ocean steam-ships, and has been found to be of gjeat service in navigation. The lamp can be readily removed from the frame for use on the vessel or about the dock, in loading or unloading. The River Projector, as shown by the cut, is of a somewhat simpler and cheaper form. THE INCANDESCENT LIGHT. I N the character and quality of the light produced the incandescent system is the most perfect means of artificial illumination yet devised. In this system the light is produced by the incandescence of a slender carbon conductor inclosed in a vacuum in a small glass globe, and is absolutely steady and uniform. The incandes- 18 THE UNITED STATES ELECTRIC LIGHTING CO. cent light has all the advantages of the arc light in safety and convenience, and is superior in steadiness and color, and more soft and agreeable to the eye. This system is especially adapted for interior illumination where comparativ'ely small lights are required, as it admits of indefinite division and distribution of the current. Although it has not the capacity of the arc system for producing large lights, and is greatly inferior to it in economy, the incandescent light has already demonstrated its ability to coDipctc successfully with gas and other systems of lighting, in many places, and is destined in the near future to supplant gas for purposes of general interior illumination. OUR INCANDESCENT SYSTEM. I N this system the IVcslou Dynamo- Electric Machine and the Maxim ineandeseent lamp are used. The Weston machine for incandescent lighti ng is in its general construction similar to that already described for arc lighting, but the winding of the armature and field magnets is somewhat modified for producing the different quality of current required. One very novel and important feature of this machine is its capacity for self-regulation. As the number of lights in circuit varies, it is necessary to v^ary the quantity of the current generated in order to prevent accidents to the lamps, and to keep them at a uniform brilliancy. This has been accomplished in other systems by manual adjustment of the machine from time to time by an at- tendant. This is obviously objectionable, as it involves the presence of an attendant at the machine, and accidents may occur, and in fact do occur in practice, from lack of attention. Mr. Maxim has devised an ingenious regulator for accomplishing this result automatically, which has attracted much attention and works well in practice. Mr. Weston, however, has been able, by a peculiar construction of the machine itself, to make it entirely self-regulating without the use of any special mechanism. This operates with such quickness and precision, that, with one h;mdred lights, for example, in circuit, ninety-nine may be instantly turned out without affecting the brilliancy of the remaining light, and without any change in the adjustment of the machine. 'Phis is the only machine ever produced ivhieh aceomplishes this most desirable result. In cases where it is desirable to vary the illuminating power of the lamps, a regulator similar to that used with the arc machines is supplied. This, however, is not used where the lights are always run at the same candle-power. The efficiency of this machine is even higher than that of the arc machine of the same type, and it is in all respects far superior to any other machine in the market. The Maxim incandescent lamp, which is shown full size in the cut on the next j)age, consists of an M-shaped carbon conductor, inclosed in a vacuum by a glass globe about two and one-half inches in diameter. The carbon is made by a peculiar process devised by Mr. Maxim, which gives it very great durability, strength, and THE UNITED STATES ELECTRIC LIGHTING CO 1 <) The Maxim Incandescent Lamp. 20 THE UNITED STATES ELECTRIC LIGHTING CO. capacity for withstanding the disintegrating effect of powerful currents. One of the Maxim lamps, constructed to give a light of twenty-five candles, was run for a short time at the Paris Exposition at an illuminating power of eleven hundred candles. We do not believe that an\' other incandescent lamp would stand such a test. The life- time of the Maxim lamp, when run at its normal power, is very long. In plants which have been erected during the past year the average lifetime of the lamps has been considerably over a thousand hours, and many lamps which have been burning from two to three thousand hours are still intact. A d}'namo-machine and ninety-seven lamps were started in the New-York General Post-Office on March 13, 1882. Since that time the machine has been running one hundred and forty hours per week without repairs or an accident, and on September ist, 1882, the average record of the lamps was eighteen hundred and fifty hours each. There were fifteen lamps which had burned continuously thirty-four hundred and fifty-six hours each, and were still in good condition. A dynamo and fifty-six lamps were placed on the ferryboat Jersey City of the Pennsylvania R. R. Co., in November, 1881. On August 29th, 1882, the plant had been in actual operation sixteen hundred and forty-five hours, and the average lifetime of the lamps was sixteen hundred and nine hours each. Our incandescent system was the first one ever put into practical commercial use. It was first introduced in the early fall of 1880, and has been in constant use since that time in the vaults of the Mercantile Safe Deposit Co., No. 120 Broadway, N. Y., in the New-York Stock Exchange, and other places. A large number of plants have since been erected, all of which are giving perfect satisfaction : among the places where such plants are in operation in New-York City may be mentioned the Hoffman House, the St. Nicholas Hotel, the National Park Bank, the Post-Office, and Washington Market. The names of other parties using this system will be found among the references at the end of this pamphlet. We manufacture incandescent lamps of different sizes, for giving a light of eight caiulles and upward. Each lamp is provided with a socket or holder, as shown in the cut on page 19, which is so arranged that the lamp when in position is held firmly, but may be readily removed for renewal ; and merely placing the lamp in the holder makes the necessary electrical connections. These holders are made with or without switches, or keys for turning the light on and off, and of various styles, plain and ornamental. Eor use with chandeliers and in similar places, it is frequently desir- able to have the switch separate from the holder, and in a more accessible and con- venient place : and a single switch will frequently suffice for all the lights on a chandelier.

These vary accord- ing to the different circumstances under which the apparatus is to be used. Among them may be mentioned the following : In the cut on page 2i is shown a supple- mentary base for the machine. This is made of hard wood, and may be constructed of any convenient height. The machine is mounted upon a sliding platform adjusted by means of a sirew shown at the right. By means of this screw the belt may be tightened or loosened at will while the machine is running.

The strips are made of different sizes, ac- cording to the current they are designed to carry.

The liootl or cover at the top is made of sheet-iron, and tlioroughly protects the lamp from the weather, and at the same time serves as a reflector. This may be applied to any form of lamp-post. When desirable, we furnish a pulley-support for mounting arc lamps, so arranged that the lamp may be readil)’ raised or lowered without inttn'fering with the light. For incandescent lamps ordinary gas-fixtures may be used by properly attaching the lamp-holders, anti the conducting wires may be carried to the lamps either through the pipes or alongside of them. We manufacture, however, a variety of special fix- tures for incandescent lamjis. The illustration below' represents an ornamental bracket designed for incandescent lamps. It is so arrangetl that it may be swung from side to side when the current is on, without in any way affecting the light. It can be taken down b}- merely loosen- ing a thumb-nut and lifting the bracket from its wall-plate. I'his wall-plate contains a safet}’ device of the same character as those shown on page 22, placed in the lamp circuit, which, in case of any abnormal flow of current, interrupts the circuit, and so preserves the lamp from injury. In the cut on the next page is shown a neat and simple fixture specially designed for use in factories, for supporting tw'o incandescent lights. The conducting wires pass down inside of the fixture, and branch off on each side to the lamps which are arranged under opal reflectors. We furnish fixtures, plain and ornamental, for any desired number of lights embodying these and other improvements, which specially adapt them to our system. cc , L>4 THE UNITED STATES ELECTRIC LIGHTING CO. ERECTION OE AI'I’ARATUS. 'I'\ furnish line wires and all necessary material for the erection of electric light- ' > ing plants sold by us, at current market rates. All our electric lighting apparatus has been approved by the New York Board of Fire Underwriters, and we have taken pains even to go far beyond their requirements in securing absolute safety, both in the construction of the apparatus and in its erection. We prefer, in all cases, to send competent and experienced men from our factory to superintend the erection of plants which we sell, charging only the time and actual expenses of the men so engaged. Where this, however, is not practicable, we furnish explicit rules for the erection of the apparatus, and insist that the purchaser shall agree to comply with them. CENTRAL STATIONS. O UR systems of lighting are w'ell adapted for furnishing lights from central stations, and many of our local companies are doing a large business in the rental of lights furnished in this way. The cuts on pages 26 and 27 are views of a station erected by the Newark Electric Light and Power Company, at Newark, N. J. This company Avas organized in March, 1882, and, within six months, was running upwards of three hundred arc lights from its station, and or- ders for additional lights were received faster than they could be supplied. The United States Il- luminating Company has Iwo-light Factory Fi.xture. upwards of SIX hundred arc lights in operation from different stations in New-York, besides a large number of incandescent lights. The New ICngland Weston Electric Light Company has about three hundred lights running in Boston. The Rochester lilcctric Light Company has about one hundred and fifty lights running at Rochester. The Citizens’ Pdectric Light Company has a large number of lights running at Toledo, O., and various others of our local com- IRinies have similar stations. We build special machines and lamps for lighting by the mast or tower system, in places where this system can be used to advantage. THE UNITED STATES ELECTRIC LIGHTING CO, MACTIIN’ES FOR K LKC'IKO- I )K !■( )Srrio\ OF MF/FALS. Weston I'^cctro-clcpositinj^ Machine sliown in the cut on tliis pa^e has -I- achieved a wide reputation, and lias in numerous competitive trials jiroved supe- rior to all other machines in the market. ,Mr. W^cston’s lony; experience in electro- mctallur^)’ has enabled him to adajit the machine very perfectly to the practical requirements of the business. It is very efficient in operation, strongly built, and will stand a great deal of hard usage. It needs no special skill for its proper management. A peculiar feature of this machine, of great value, is the automatic switch for prevent- ing a reversal of the polarity of the machine. As is well known, an electro-depositing bath acts as a battery tending to produce a current in an opposite direction to the current from the machine ; when the machine stops, or any accident happens to it by which its electro-motive force is reduced below the electro- motive force at the electrodes of the bath, a current flows back through the field magnets of the machine and reverses their polarity, and upon again starting the ma- chine the direction of the current is reversed, thus removing the de- posit from the articles in the bath, and in many instances, if not ob- served in time, destroying them and seriously injuring the solution. The automatic switch or cut-off used with this machine, which is shown in the lower right-hand corner of the cut, entirely prevents this, as it cuts the machine out of circuit upon any considerable diminution of speed. W'e shall shortly publish a special catalogue of this apparatus. EI.F.CTRIC MOTORS. /\ LL of our electric light machines, especially those for running incandescent lamps, are well adapted for use as motors. We build special sizes of motors to order, fit them with regulators, and supply various other devices for a complete system of transmission of power by electricity. A special catalogue of this apparatus will also be issued soon. Weston Electro-depositing Macliine. PRICE-LISTS.

Gentlemen : — \\'e have been using four of your ten-light machines for nearly one year, and find them to work in the most satisfactory manner. W'e find the lights not only very powerful, but steady; the color perfectly white, which makes it very agreeable to our employees. We find it particularly adapted to our work of all classes, machine-rooms, foundries, paint and ornamental room, as also for office use. In fact, we would not be without them. Another great point about them to be considered is, the machines can be operated by the same engines in conjunction with other machinery. \\’e are very truly yours, Richard T. Pullen, Secretary.

Gendcmen : In reply to your favor asking if the lights you put in for us are still giving satis- faction, would say : We have used a forty-light plant in our establishment for the past twelve months, with the most pleasing satisfaction. Your light has proven even more satisfactory than you claimed for it. During the whole time of its use we have had no trouble or mishap. We now contemplate enlarging our premises, and ivill want some twenty lights more. Our gas-bills for the year previous, in the smaller house, ran as high as $4,000.00 per annum. By actual estimate the expense of illuminating the present premises (more than double as large) will not exceed $3,500.00 jier year.

Gentlenicn : We had one of the ten-light Weston machines, with engine complete, put on our steamer Cetiis, at the same time we were using the Brush Light on our pier. The success attending the lighting of this first steamer was so great that we decided at once to light the remaining boats which we had contemplated ‘lighting, namely, the Taurus, Pegasus, and the Cepheus. The color of your light is remarkable for its purity and absence of any blue shade peculiar to all others. The boats are subject to jjretty rough handling in a heavy sea, yet the lights run with perfect steadiness. .\lthough the lights are necessarily hung quite low, the porcelain globes which your company have provided produce an effect unequaled by any other means of illumination. The engine furnishing the lights is frequently run with 15 or 20 lbs. steam-pressure, showing the economy in the jiower consumed in your system. W'e think that your light is well adapted to the illumination of every class of river and ocean steamers. Yours truly, CiEO. S. Scott, President. New-York, January, 9, 1882. I'iufJENF. T.

Gentlemen : I was the first to introduce the electric liglit in iny line of busine.ss. 1 am glad to have the ojjportimity of testifying as to its efficiency and economy. In April, 1878, I contracted with your company for six dynamo-machines and twelve lamps, which pnrved so satisfactory that I have since increased the number to twelve machines and twenty-four lamps. The light enables my customers to distinguish a difference in the .shade of color in goods as easily by night as in daylight, and I have always been pleased with it on the score of economy, cleanliness, and freedom from smoke and bad odors from gas. Respectfully, .\. Nicoll. New- York, December 17, 1881. The Uniied States Electric Lighting Co. Gentlemen : T have in use at each of my theaters thirteen of your electric lights, and am highl\- pleased with the satisfiiction they have afforded, not only to those connected with the theatres, but to the public as well. At the time I exjierimented with the lights for theater purposes, it was generally siqrposed that they would prove unsuitable for the lighting of an auditorium, and that they could not be utilized to the same extent as gas. I am happy to be in a position to state that all the objec- tions urged against their use in theatres have proved unfounded, and that, at a great saving of expense and labor, they furnish a much superior light to any obtainable under the old system. 1 congratulate you upon the improvements you have introduced, and look for the time when you will have reached that jierfection which will in itself commend your lights to general use. Until you reach that position, you can make free use of my name and theaters as a guaranty that, in your “ electrics,” managers and proprietors of places of public amusement will find the cheapest and best illuminating power for their purposes. Yours, very truly, Harry Miner. The North Chicago Roi.i,ing-Mill Company. South Chicago, August 30, 1882. The United States Electric Lighting Co., New-York. Gentlemen : The work of erecting and putting in running order our electric lighting jilant, begun by Mr. Young, has just been completed by Mr. Erank Badt, and, on the eve of the latter gentleman’s departure, I take the opportunity, and with great jileasure in so doing, to testify to the excellent workmanship displayed by both gentlemen. Our plant of four machines and forty lamps is now entirely in operation and giving the most satisfactory results. Everything does just what was claimed for it, and the general excellence of the plant is due, I think, in a large measure to the careful and workmanlike manner in which it was put together, and the great attention paid to the slightest details. It gives me pleasure to add my testimonial of the excel- lence of your lighting system, and we regard ourselves as fortunate in its possession. I am yours, very truly, E. C. Pori'ER, Superintendent.

We are using a comparatively small engine and boiler for running them, which gives us an opportunity of judging of the co.st of the light, ^\'e find it a great improvement over gas, which we have entirely discontinued, and it gives our customers the advantage of selecting goods bv night as well as by bright sunlight, thus nearly doubling the hours in which we can sell goods. ^\'e have no hesitation in saying that your system is by far the best in use. Yours truly, Smith, Cray &: Co. Office of The Rockaway Beach Hotel. Rockaway Beach, September 3, 1881. The United States F'lectric Lighting Co., 120 Broadway, New-York. Genllemen ; 'I'he ten-light \\'eston machine and lamps that you put in for us some weeks ago are running to our comjilete .satisfaction. Having had exjierience heretofore in various electric lamps, knowing the power consumed and care recpiired in keeping them in order, we feel confident that we have by far the best system in existence for electric lighting. 'I'he machine was put up at a very short notice, and is driven from an ordinary engine on the premises, and was turned over to our engineer within a few days from starting, since which time we have had no difficulty whatever in maintaining the lights without interrujition. 38 THE UNITED STATES ELECTRIC LIGHTING CO. One of the ten lights I experimentally had suspended from the ceiling of our main par- lor, one of the largest in the country, and the result is past all conception. It has displaced forty-two five-feet burners (gas), giving a far steadier, more powerful, and brighter light than we have ever had in the same room. We find the color is not at all objectionable to the ladies, the complexion remaining the same in the light, unlike all other electric lights that we know of, that give a blue, ghastly appearance. Regarding the relative cost as compared with that of gas, a point I have hitherto been un- able to ascertain, I can now give correctly, viz. : six of the ten lights now save me thirty-five thousand feet of gas per week, w hich, at the price I pay for gas, viz., $3.50 per thousand, equals a saving of $122 per week, less the cost of running the entire ten lights, which is $40 per week, showing a net saving of $82 per week, with four lights to spare. I am very respectfully yours, O. G. Burn.ap, Manager of the Rockaway Beach Hotel. The Trenton Iron Company. Trenton, N. J., September 5, 1882. The United States Electric Lighting Co., New-York. Gentlernen ; We take pleasure in stating that we have had one of your Weston ten-light machines in operation at our works for several months past, and that it has operated very satis- factorily.

Syracuse, N. Y., April 20, 1881. To u>hoin if may concern : At the request of Mr. Teall, we cheerfully make the following statement as to our experience with the electric light : Mr. Childs and myself were appointed by the “ Board of Directors ” to go to Xew-York and examine the different electric lights. A\'e did so, and in our opinion the Weston light was a whiter light than the Brush. The bluish tinge, which is characteristic of the Brush light, seemed to be absent from the Weston light. 'I’he power seemed to be much less per light with the Weston than it did with the Brush, from the indicator cards that were taken from engines running electric lights of both manu- facturers. We have been running the Weston light for about two months, and it has been running very satisfactorily, and has not caused any trouble. And we think the estimate of three-fifths of a horse-power to a light of a so-called two thousand candle-power, would not be out of the way as a fair estimate of the actual power when in common use. Yours truly. The Porter Manufacturing Co. (Limited). G. A. Porter, Treas. Albany, N. Y., July 28, 1881. To whoever it may concern : This is to certify that we have used the Weston Electric Light Machine in our stores for the past seven months, and believe it to be the best machine for light- _ ing purposes yet produced. d'his light takes only about one-half as much power to each light as the Brush or any other machine that we know of. We were running the Brush sixteen-light machine for Messrs. W. M. Whitney &: Co. last fall, and, as near as we could ascertain, it took over twenty horse-power, while the Weston would not take over ten horse-jiower for the same number of lights. \\'e also find the Weston lights are much more powerful, and of a much better color, and steadier. Yours respectfully, R. Strickland & Co. Office of the Congress and E.mpire Spring Co. Sar.atoga Springs, N. Y. 'I'o the Weston Electric Light Company, 120 Broadway, New-York.

Dear Sir : In answer to your inquiry if the light we have is an advantage to us, and is what you represented it, I would say, that we formerly used gas in this depot, and we have been using the electric light between four and five months; and I must confess that it surj)asses anything yet, and we cheerfully recommend it to all transjjortation companies to light their freightdiouses or docks, where they are obliged to do much night-work. It facilitates our work; we can read the marks on freight packages the same as by daylight, and we find that there are less errors than formerly. We hold and make business by giving it (juick dispatch, and \ve think that this electric light will assist us to do this without any e.xtra expense. I remain, yours respectfully, J. B. Hubbell, Supt. X. Y. Stock Exchanxe Building Company, Safe Deposit Department. New- York, June 17, 1882. The United St.ates Electric Lighting Company, 120 Broadway, New-York. Gentla/icu : In reply to your inquiry concerning the incandescent lights which you put in the vaults of the Stock Exchange about a year and a half ago, I would say they are highly satisfac- tory. They are perfectly steady, and give a bright, yet soft and pleasant light, being superior to gas not only in this respect, but also in the fact that they do not consume the oxygen of the air, and produce no heat of any consequence. Yours truly, Edwin J. Coles, XdYv. Social Manufacturing Company, Globe Mill. Woonsocket, R. L, Jan. 10, 1882. The United St.ates PWectric Lighting Co. Gentlemen: We started the machine on your incandescent system on October 10, 1881, and from that date to January 9, 1882, they have run 238^;^ hours. We have burned on the two ma- chines together one hundred and seventeen lamps, and have obtained I'rom them ample light for four looms per lamp. During the 2^8^ hours eight of the lamps have burned out. The light is perfectly steady, and, from the ease with which it can be distributed, and absence from shadows and flickering, we consider it, for our purpose, much superior to the arc light. It has given us no trouble, and, so far, we are very much pleased with its operation. \'ery truly, Henry F. Lippitt, Sn/t. John H. Davis & Co., 17 Wall Street. X"ew-York, June 17, 1882. Secretary U. S. Electric Lighting Co., N. Y. Gentlemen: In reply to your inquiry regarding your electric lights for offlce and dwelling- house, we beg to say that we have had them in our office for nearly a year, and that they gi\-e entire satisfaction, so much so that we have had all our gas-pipes removed. \\'e have in all eleven burners, and the light they give is fully equal in brilliancy and steadiness to the best gas, and is free from the odor, heat, and vitiating properties of the latter. It has made a great differ- ence in the purity of the atmosphere and general comfort of the office. Yours truly, John H. D.avis 8: Co. 42 THE UNITED STATES ELECTRIC LIGHTING CO.

During the month of December, with sixty-four lights; they ran 222 hours, during which time but one lamp gave out, from defective carbon, and this burned out within an hour from lighting. This will give an average of nearly 9 hours per night. Very truly yours. The .Maxim Ki.ectkic Light and Power Co., F. M. Nichols, Secretary. I'he Western Mail. Cardiee, Wales, August i, 1882. My Dear Sir ; Vour Maxim Incandescent lamps have given us the greatest satisfaction. .\fter trying various systems of electric lighting for our editorial office, case-room, machine-room, etc., we have arrived at the conclusion that your installation is at once the most efficient and economical that we can have. MT are able to speak of it with the more confidence as we have now (kqiended upon this mode of illumination for nearly three months. As regards comparative e.xpense, 1 am not in a position to state exactly how the cost of electric lighting stands, as the motive power in our case is already at hand. Put this 1 will say, that if the electric light costs us ten, or even twenty, per cent, more than we were formerly paying for gas, I would gladly pay the difference to be rid of the deleterious products of combustion which, under the old system, nightly poisoneil the atmosphere which newspaper men are unfortunately compelled for so many hours to breathe. You may form some idea of the relief which the electric light affords us when I tell you that, tested by the thermometers we have hanging in our various rooms, the temperature under that system is from ten to fifteen degrees lower than when, under precisely similar conditions, the gas-lights are burning. As a mere matter of health, the electric light is bound, so soon as it becomes practically available to the iniblic, to supersede every other mode of illumination. My experience leads me to believe that, under favorable circumstances, it can be produced more cheaiily than gas. As regards its efficiency, I can only say we produce a morning paper by its means every day, and 1 shall be glad to show it in practical operation, and give every in- formation in my jiower as to its cost, to any one who may take an interest in the subject. Faithfully yours, Lasceli.es Carr, Editor. The Fleceric Light and Lower (generator Co.mpanv, Li.mited. 47 Cannon Street, I.ondon, F. C., May 19, 1882. C. W. Heiiard, Ks(p, United States Electric Liy^hting Co., 120 Broadway, New-York, U. S. A. Dear Sir : 1 beg to acknowledge, and thank you for, your letter of the ist inst. My directors are much gratified at the results you report, in the working of the Maxim lamps on the ferry-boat, as the figures confirm our exiierience with the lamps at Edinburgh General Lost-office, where we have had fifty-one burning for the past six months. They also give great satisfaction at the Glasgow Fine .Yrt Galleries, the Norwich Free Library, the Prince of Wales I’hcater, at Liverpool, Risca Colliery (in South Wales), and many other places. The Marquis of Salisbury is also increasing the number he has in use at Hatfield Hou.se. At the recent royal wedding at Windsor the Maxim lamps were used for many nights in the quadrangle of the castle, and the Maxim search-lights were also exhibited in use to the Queen. 'The double Weston lamps have been in use some time (thirty-two of them) in Queen Vic- toria street, in the city of London, and the general verdict on them is that they surpass all that has been previously seen in the way of electric lighting. I am writing Mr. Hartley regarding the supply of machines, etc. I am, dear sir, yours faithfully, F. H. Landon, Secretary.
