ERECTING 

 THE WORK 



surface of the metal sheet, prepared as has been de- 

 scribed. The door is then varnished, baked ;iml 

 rubbed, and is finished, so far as the factoiy opera- 

 tions are concerned. 



Having the mechanical and ii'sthctie featuies 

 fully develo|>cd, it may be well to consider the erec- 

 tion of the work and how it compares with that of 

 other material. The door can be placed in a build- 

 ing many weeks earlier than a wooden door, for there 

 is no fear of its swelling or warping, due to damp- 

 soon as erected it immediately comes into 

 efficient service, an advantage often 

 of the utmost importance. The 

 dangers of marring the door art- 

 slight, because the enamel is baked on so thoroughly 

 that blows, due to carelessness of workmen, do not 

 readily mar the finish as they would that of a wooden 

 door. The finish being complete before the work 

 leaves the factory, the necessity of finishing on the job, 

 where there is exposure to dust, is entirely obviated. 

 The door jamb and casing are fastened directly to 

 rolled iron channels or angles placed in the openings 

 before plastering, or wooden "bucks" fastened to 

 these channels may be used and the door jambs 

 fastened thereto. The wooden "bucks" are com- 

 pletely covered by the steel jamb and casing, and the 

 door hinges are fastened to the iron channel with 

 machine screws, thus obviating the dependence upon 

 the wood to bear the strain of the weight of the door. 

 The advantage of this latter method is apparent. 



VARIETY 

 OF STEEL 

 TRIM 



The doors can be erected much faster than wooden 

 doors, as all measurements are exact and once in 

 place there is no necessity for rehanging, due to 

 swelling or other causes. 



The visitor will notice a large number of steel par- 

 titions, picture moldings, window trim, corridor 

 lights, wainscoting, cap and many 

 other items required for the com- 

 plete interior equipment of this 

 modern building. The methods of 

 manufacture in each case are almost identical with 

 those described. It is well to note the features in- 

 troduced in the steel partitions, whereby they can be 

 quickly taken down and reerected in any desired 

 part of the building. Variations in lengths and 

 heights are taken up by adjustment provided for in 

 the "filler" pieces on the sides and top. All of the 

 sheet metal doors, partitions, and trim in the Singer 

 Building were made and erected into place by the 

 Dahlstrom Metallic Door Company, of Jamestown, 

 X. Y. New York office at No. -29!) Broadway. The 

 paneled steel wainscoting on the 34th floor, shown 

 in the accompanying illustration, is worthy of notice 

 as it produces a remarkably cozy effect in the room. 



Briefly stated, the advantages 

 gained by the use of doors, parti- 

 tions, trim, etc., of the Dahlstrom 

 System are: fireproof ness, dispatch 

 in completion of the building, uniformity of design 

 and color, durability and utility.

SAFETY DEVICE FOR WINDOW CLEANERS 



TIIK Whitner Safety Device for outside window 

 cleaners, as attached to the Singer Building, 

 consists of bronze bolts screwed into the 

 metal window casings, two on a side. The window 

 cleaner wears a regulation belt, made in the usual 

 fashion, of heavy frames, fourfold and double stitched, 

 provided with aluminum bron/e terminals and brass 

 rope eyes. The window cleaner raises the window, 

 attaches one of the terminals to the belt, steps out 

 upon the window ledge, attaches the other terminal 

 and is securely fastened to the building, with no pos- 

 sibility of falling, both hands being left free to work 

 with. The belt is so constructed that he is permitted 

 to move from one side of the window to the other. 



Ten years ago it was difficult to convince archi- 

 tects and builders that it was necessary to protect out-
