  QUINCY, MANCHESTER, SARGENT COMPANY.

  Quincy, Manchester, Sargent Company will be the name under which, upon and after February 24, 1906, the business of the Railway Appliances Company of Chicago and New York will be carried on. The new organization will include the Railway Appliances Company, Q. & C. Company, Pedrick & Ayer Company, Bryant Metal Sawing Machine Company, Q. & C. Pneumatic Tool Company and Aper Manufacturing Company, with factories at Chicago Heights, Ill., and Plainfield. N. J.

  The list of devices manufactured by the new company is a considerable one. Those deserving of principal mention, however, are Q. & C. metal sawing machines, Stanwood steps, Q. & C.-Priest snow flangers, Ajax diaphragms, Gilman & Brown emergency knuckles, Fewings car and engine replacers, improved Pilling turntable motor, Pilling air motors and the entire line of the Pedrick & Ayer Company, including electric, air and pneumatic hoists, riveters, cranes, locomotive repair tools, etc. The company are also the exclusive sales agents for the Ronzano rail joint company, the Dustless Roadbed Company, the National Elastic Nut Company and the railroad department of the Olds Motor Works.

  Members of the new company have been identified with the railroad trade for many years.

  Mr. C. F. Quincy first became interested in the Dunham Manufacturing Company, manufacturers of the Dunham car doors, in 1887. He afterwards became president of that company, and later on the name was changed to the Q. & C. Company. This company became interested in other car door fixtures, the entire line, however, later being sold to the present Camel Company (although the manufacture is still carried on at the Chicago Heights plant). The Q. & C. Company acquired the Bryant Metal Sawing Machine Company and became well known in connection with the Servis tie plate, adding to that afterwards the Q. & W. tie plate, Mr. Quincy being practically a pioneer in the tie plate business, which today is of considerable importance. For about two years the business of the Q. & C. Company was operated in common with the Railroad Supply Company, and in that name, Mr. Quincy being president of the company. Just before 1903 the business was again divided, the Railroad Supply Company continuing with the tie plate business and the Q. & C. Company being consolidated with the Railway Appliances Company, of which Mr. Quincy was president until the present time. when he becomes president of the Quincy, Manchester, Sargent Company.

  Mr. George H. Sargent, vice-president, was for some years connected with the sales department of the Congdon Brake Shoe Company and its successor, the Sargent Company, and, together with Mr. Percival Manchester, also in the employ of the Sargent Company, formed the Railway Appliances Company, Mr. Manchester being the secretary and treasurer. The business was conducted by these two gentlemen until its consolidation with the Q. & C. Company, the well known Gilman & Brown emergency knuckle. Fewings car and engine replacers and the Ajax diaphragms being some of the devices introduced by them to the trade. Mr. Sargent will be vice-president of the new company and Mr. Manchester secretary and treasurer.

  Among the directors of the company will be W. D. Sargent, formerly president fo the American Brake Shoe & Foundry Company and vice-president of the American Steel Foundries; Henry S. Manning, formerly of Manning, Maxwell & Moore, and William C. Boyden.
