Features of Superiority 
 
 AMERICAN PEERLESS 
 WALL RADIATORS 
 
 HE AMERICAN Peerless Wall Radiator is the foremost 
 
 improvement in the heating field, for it replaces the 
 troublesome pipe coil and other antiquated types of heat- 
 ing surface. As the pipe radiator of years ago was replaced 
 by the cast-iron form, so the coil has been supplanted by 
 the AMERICAN Peerless Wall Radiator. 
 
 The AMERICAN Peerless Wall Radiator was developed 
 to supply a demand for efficiency, and it has been suc- 
 cessful. A study of the design will show elimination of 
 friction-giving passages, which feature allows operation 
 with less power, pressure or vacuum, as the case may be, 
 and eliminates many air-venting problems. 
 
 The mechanic approves of this type of radiation, since 
 he can always make a proper circulating as well as a good- 
 
 looking job. The owners will like it because it looks better, 
 fits in better, is more efficient, and occupies less space. 
 
 The AMERICAN Peerless Wall Radiator does not wear 
 out. The story of replacing heating surface after a number 
 of years is now obsolete, for AMERICAN Peerless Wall 
 Radiators are a part of the building as much as the ground 
 upon which it is built. Being made of cast iron, it can 
 stand the roughest use in any type of heating plant. The 
 sections are connected together by means of heavy right- 
 and left-hand nipples of malleable iron, and the connect- 
 ing openings are made with cast-iron bushings. Nipples 
 are several times the weight of standard pipe (this at the 
 thread line). Being made of malleableized iron, these 
 nipples exhibit the same remarkable resisting qualities to 
 the action of steam and water as does the radiator surface.

 Features of Superiority —Continued 
 
 We gladly supply, on request, a series of laboratory test 
 sheets showing, under 2 pounds steam pressure at boiler, 
 an average coefficient of 2.121 per square foot of AMER- 
 ICAN Peerless Wall Radiators. 
 
 The water content of these Radiators is about fifteen- 
 hundredths of a gallon per square foot. 
 
 All regular AMERICAN Peerless Wall Radiators are tested at 
 factory to 100 to 120 pounds pressure. Radiators for higher 
 working pressure than 40 pounds can be made on special 
 order. Sections weigh about 7 pounds per square foot. 
 
 Many combinations of groupings can be made and, with 
 a little thought, very successful applications are possible. 
 
 AMERICAN Peerless Wall Radiators never lose their value. 
 If a building is remodeled, extended or otherwise altered, 
 
 they can always be used again without loss—100 per 
 cent salvage! 
 
 Ingenious methods of supporting AMERICAN Peerless Wall 
 Radiators are shown—on walls, on ceilings, on girders and 
 in almost any part of the building. As illustrated, the in- 
 stallation is simple—the Arco Brackets, Supports, 
 Hangers, Pendant Flights, Post Supports or Inserts being 
 set and the Radiator placed on them and adjusted for 
 pitch. These splendid devices, together with the Clearway 
 Forms and Backset Connections, constitute an unequaled 
 line of accessories, which will do much to advance and 
 popularize heating. 
 
 The following pages contain descriptive matter, show- 
 ing methods of application, measurements, surface, in- 
 Stallations, telegraph code, etc.

Arco and Arco Junior Adjustable Brackets 
 
 RCO Adjustable Wall Brackets have many unusual 
 
 features and fulfill the demands of the most difficult 
 
 installations. They are strong, easy to erect, adjustable, 
 and they make a neat and attractive job. 
 
 Expansion and contraction are provided for, no matter 
 how long the run of Wall Radiators may be. The spools 
 on the bottom Bracket allow a free horizontal movement 
 of the Radiators, thus taking care of any difference in 
 “‘roughing in’’ measurements, and affording free play for 
 expansion and contraction. Unsightly, sagging, air-bound 
 runs of pipe coil need no longer be tolerated. 
 
 The V-shaped spool makes it impossible for the Radiator 
 to jump from the Bracket. The finger of the top Bracket 
 guides the Radiator and keeps it from tipping forward. 
 
 By the use of these Brackets, which permit a vertical 
 
 AMERICAN PEERLESS 
 WALL RADIATORS 
 
 adjustment of 2 inches, the fitter can adjust for ‘“‘pitch”’ 
 after they have been attached to the wall. The Single- 
 Spool Brackets set the outer face of the Radiator 434 
 inches from the wall. Retaining bolt is 14 inch diameter. 
 
 Bearing plates and bolts of ARCO and Arco Junior Ad- 
 justable Wall Bracket are of wrought iron. The remainder 
 of the Bracket is made of malleable iron. 
 
 Arco Junior Wall Bracket 
 The Arco Junior Wall Bracket is made for smaller units 
 of radiation; it requires only one bolt for fastening, as 
 shown; has an upright alignment of 11% inches and a hori- 
 zontal slip of 1 inch. 
 
 This type of Bracket can be economically used on all sizes 
 of AMERICAN Peerless Wall Radiators where extreme 
 expansion is not to be considered.

Good Practice for Installing 
 
 Ahee increasing use of AMERICAN Peerless Wall Radi- 
 ators, hung on ARco Adjustable Wall Brackets to 
 walls and partitions, prompts us to suggest the following 
 simple and practical methods of installation, which insure 
 good jobs. 
 
 For attaching ARCo Adjustable Brackets to stone, cement 
 or brick walls the proper use of the expansion bolt always 
 gives the best results. Ordinary nails and screws frequently 
 work loose, pull out or break and cannot be depended 
 upon for secure and permanent work. 
 
 Progressive fitters have found that the following method 
 saves time and gives best results: 
 
 To start the hole in the wall, use a “‘rose drill.’’ After 
 carefully locating the hole centers, start the hole with light 
 
 AMERICAN PEERLESS

 blows of the hammer, being careful not to allow the drill 
 
 to jump about. Thus a smooth bore is started without 
 
 cracking the surface of the wall adjacent to the hole. After 
 hole has been drilled about 14 inch use more force, being 
 careful to turn the drill slightly between 
 blows, as this prevents the cutting edges 
 striking the same point twice and produces 
 more rapid work. (Fig. 128.) Drill hole

 project beyond the inner end and enable turning the 
 work up tight to the wall when the screw is turned in. 
 
 Where few holes are to be drilled a hand hammer with a 
 rose drill will give good results, but for larger work requir- 
 ing numerous holes a great saving in time may be made by 
 using a “Rapid Fire”’ drill. This drill works similarly to 
 a pneumatic hammer. 
 
 After the hole is drilled accurately the shield can be in- 
 serted by hand or lightly driven in by hammer. (F ig. 129.) 
 Drive beyond the face of the wall. Then place the plate or 
 bracket to be attached, over the shield; then insert lag 
 screw by hand as far as can be turned and continue turn- 
 ing with hand wrench or socket wrench in a brace until it 
 has tightly drawn the work up against the wall. (Fig. 130.)

 If lag screw binds at any point 
 due to grit from wall, give it a 
 reverse turn and then continue.

AMERICAN PEERLESS 
 WALL RADIATORS 
 
 For Roundhouses and Bulkheads 
 
 ANY engineers maintain that railroad roundhouses 
 should be equipped with blower systems, but never- 
 theless a great deal of Wall Radia- 
 tion is used in this class of buildings. 
 In many cases both systems are used. 
 
 AMERICAN Peerless Wall Radiators 
 are adapted excellently to round- 
 house engine pits. They are narrow 
 and, when mounted on Arco Adjust- 
 able Wall Brackets, do not extend 
 out more than 434 inches from the 
 wall. They serve particularly well 
 when the heating surface in these 
 engine pits is recessed. 
 
 Fig. 136. AMERICAN Peer- 
 less Wall Radiator recessed 
 inside wall of engine pit. 
 
 AMERICAN Peerless Wall Radiator 
 
 “A” sections are only 13,5, inches in height. Therefore a 
 run of many of these rons assembled end to end, may 
 be set in an engine pit at a pitch that is sufficient to in- 
 sure perfect drainage. 
 
 The new Arco Adjustable Wall Bracket is perfectly suited 
 for the work that is required of it. The fact that its ad- 
 justment may be accomplished after the Wall Radiators 
 are set in place is exceedingly important. By reason of 
 this feature the contractor using AMERICAN Peerless Wall 
 Radiators finds that his labor item is agreeably reduced. 
 
 AMERICAN Peerless Wall Radiators, used in bathrooms, 
 halls, kitchens, food-packing plants, butcher shops, res- 
 taurants, Turkish baths, laundries, lavatories, hospital 
 operating rooms, sick wards, etc., leave a clear space be- 
 neath them which can be easily scrubbed or cleaned.

 Arco Trapeze and Slip End Supports 
 
 Ree the necessity for a change from the make- 
 shift arrangements used for strapping or hanging 
 pipe, conduits, radiators, etc., from ceilings, beams or 
 girders, we have designed these ARCO Trapeze Supports 
 with the view of furnishing a permanent as well as an 
 adjustable and neat-appearing hanger.

 show the Arco Trapeze Support employed in 
 hanging an AMERICAN Peerless Wall Radiator, 
 with its supply and return pipes, in addition 
 to plumbers’ pipes. 
 
 Any arrangement or combination can be as- 
 sembled on the job quickly by using standard 
 nipples or cut pipe slipped over rods between 
 Supports. The ARCO Slip End Supports, in

 FTEN it is highly desirable to employ AMERICAN Peerless Wall Radi- 
 
 ators as Ceiling Radiators. Nothing detracts so greatly from the 
 appearance of an installation as the employment of makeshift, insecure- 
 appearing straps, bands, chains and the like, whereas the orderliness and 
 neatness of the heating installation receive much favorable comment where 
 the hanging of ceiling radiators and piping is simply and sturdily effected 
 by use of these substantial and reliable ARCO Trapeze and Slip End Supports. 
 
 Besides, these ARCO Trapeze and Slip End Supports permit easy adjust- 
 ment in pitch of piping and radiators or conduits at any time, whether to 
 make up for irregularities in setting or in settling of the building. 
 
 The slight difference, if any, in cost is more than offset by the lower labor 
 cost in erecting and adjusting these Supports. 
 
 A few examples of arrangements of these Supports are illustrated in 
 pages 26, 30 and 45 to 47.

Arco Clearway Forms 
 
 RCO Clearway Forms, as shown on opposite page, 
 have been successfully and economically used. When 
 placed in a pier or pilaster, a clear pathway is made for 
 the piping, thus overcoming the unsightly and expensive 
 practice of elbowing around these projections. These forms 
 should be delivered to the builder with instructions as to 
 their positions. These are made to take up the height of 
 two and three flat brick courses. 
 
 ARCO Clearway Forms can also be used on overhead pip- 
 ing where it is desired that pipes be out of the way of 
 other apparatus. 
 
 Placing these Forms end to end at the center of the wall 
 radiator tappings enables units of any length to be made 
 —all radiators between piers being connected together on

 a straight line. ARCO Clearway Forms are made of cast 
 iron, in three sizes, as listed on this page. 
 
 Where there are deeper recesses between piers or pilasters, 
 the ARCO Backset Connections, as illustrated on page 35, 
 offer a mechanically skillful means of neatly disposing of 
 the radiators, causing them to hug the wall closely.

 When AMERICAN Peerless Wall Radia- 
 tors are used as a railing, the top may 
 be left plain or, if desired, an extra set 
 of Legs or Supports can be run along 
 the top, and on to this a wood or other 
 railing top can be placed. When shelf 
 or rail is made to fit close to wall, it 
 acts aS a wall shield as well as a con- 
 venient rail or bracket. 
 
 A further use for AMERICAN Peerless Wall Radiators is 
 in apartments where they will set in close to the wall, 
 
 434 inches being the distance from back line to face of 
 Radiator.

Arco Greenhouse Radiator Post Supports 
 
 Ate Greenhouse Radiator Post Supports give to greenhouse men 
 a long-sought, permanent means of installing radiator heating sur- 
 faces under benches, and insure a construction doing away with the vex- 
 atious, costly troubles from sagging, trapped coils and split headers. 
 
 These Supports are made in size to 
 cap a 5-inch concrete molded post. 
 (See Fig. 201, page 50.) The two ears, 
 with their 5£-inch rods, uphold the 
 ARCO heavy cast-iron saddles, upon 
 which rest the stacks of AMERICAN 
 Peerless Wall Radiators. The threaded 
 rods permit raising or lowering the 
 saddles, to insure correct drainage of 
 heating surfaces and piping as long as

AMERICAN PEERLESS 
 WALL RADIATORS 
 
 HCHER Working Pressures— AMERICAN Peerless Wall 
 Radiators are regularly tested at the factory at from 
 100 to 120 pounds cold water pressure, but where higher 
 working pressures (steam or water) than 40 pounds are re- 
 quired order must specifically so state. In these cases wall 
 radiators are furnished only with outside hexagon nipples. 
 
 For Convenience in Handling and Shipping in less than car- 
 load lots, unless otherwise ordered, No. 5-A Radiators will 
 be assembled in stacks not exceeding six sections; No. 7-A 
 Radiators in stacks not exceeding four sections; No. 9-A 
 Radiators in stacks not exceeding three sections; and Nos. 
 7-B and 9-B Radiators in stacks not exceeding seven sec- 
 tions. See page 54 for schedule of shipping Wall Radiators 
 in stacks or units, as followed in our factory practice, un- 
 less otherwise ordered. 
 
 Directions for Ordering 
 
 When Erecting Large Stacks— When fitter intends to 
 erect a stack consisting of more sections than above men- 
 tioned, or when the sections or stacks are to be set in 
 rows or series (as shown by illustrations on pages 58 to 60), 
 we provide a right- and left-hand threaded nipple having 
 hexagon nut at center, enabling the fitter easily to connect 
 the stacks or rows on the job. 
 
 The 11-inch right- and left-hand threaded internal nip- 
 ples have two heavy inside lugs so that an ordinary piece 
 of l1-inch round iron, flattened at one end the length of 
 nipple, can be inserted to any desired point in the Radia- 
 tor, and by applying an ordinary wrench to bar the nipple 
 can be screwed or unscrewed and one or more sections may 
 be added or taken out. We can furnish these bars (Direct 
 Radiator Wrenches) in 4-foot lengths.

 figure number showing assemblage. 
 60.) The first numeral in each of the following figure 
 numbers indicates the size of section, thus: Fig. 511 
 means 5-foot sections arranged in the manner as shown 
 in sketch above the number; Fig. 711 refers to 7-foot 
 sections and to the same assemblage; and Fig. 911 refers 
 to 9-foot sections and to the same assemblage. 
 
 Assemblages—Sections are always assembled with bars 
 vertical for greatest heating efficiency. The figures shown 
 on these pages illustrate the common ways of assembling 
 comparatively small units, but AMERICAN Peerless Wall 
 Radiators can be assembled in any number of sections, 
 either longer or higher than shown in the figures. It is 
 
 Assemblage Figures and Tappings 
 
 our practice, however, when a greater number of sections 
 are specified than exactly shown in the figure, always to 
 build on to the length, maintaining the height as shown in 
 the figure. The safe way in ordering is always to send 
 sketch unless you are ordering exactly the number of sec- 
 tions as shown in the figure. 
 
 Regular and Special Tappings—The regular tappings of 
 AMERICAN Peerless Wall Radiators, as shown on the 
 following pages, are indicated by Nos. 2, 3, 4, 5, 6, 7, 8 
 and 9. Nos. 20, 30, 40, 50, 60, 70, 80 and 90 indicate special 
 tappings which can be furnished if desired and for which 
 an extra charge will be made. Tappings are 11% inches, 
 supply and return, and bushed as desired. See also
