THE INDIA RUBBER WORLD 



[Juke i, 1908. 



laboratory. As a matter of interest to those who believe in 

 laboratories, the general equipment consists, primarily, of a fire- 

 proof building with plenty of light and with concrete floors. The 

 interior is finished in white, with the exception of ebonized acid 

 proof tables, which are black. For general equipment there is a 

 ventilating apparatus with hoods for the removal of acid vapors, 

 and the building is piped for gas, steam and compressed air, and 

 wired for electricity. 



To itemize the great variety of retorts and special vessels of 

 glass, platinum, aluminum, and hard rubber would require a deal 

 of space, and, indeed, it is more interesting to put emphasis, 

 for example, upon such special contrivances as the solid concrete 

 pile set deep in the earth to prevent vibration to which is at- 

 tached the sensitive analytical balance. The illustration herewith 

 shows only a part of the laboratory proper. Another portion of 

 it not shown is that in which is now being installed experi- 

 mental machinery, such as a small mi.xing mill, a dry heater, 

 vulcanizer, press, and a specially strong steel vulcanizer for high 

 pressures. .\ portion of the department is also reserved for 

 special testing machines now being constructed. 



At the recent election of officers of the Trenton Rubber Manu- 

 facturing Co. the various positions were filled as follows : Joseph 

 O. Stokes, president ; William J. B. Stokes, treasurer ; Frederick 

 N. Hamerstrom, general manager; Francis C. Lowthrop, secre- 

 tary; Fred S. Wilson, assistant secretary; Robert J. Stokes, 

 superintendent. The following office appointments were made : 

 J. Harry Thompson, office manager; .-Mbert N. Numbers, man- 

 ager mail order department; R. Sidney Woods, general auditor; 

 L. T. Kuhl, credit man ; James Driscoll, chief chemist.

NEW RUBBER FACTORY APPLIANCES. 



A FABRIC MAKING MACHINE. 



\ MONG the interesting inventions that have recently been 

 *^ filed in the United States patent office were two along the 

 lines of fabrics for tires and hose. They are the joint inventions 

 of Eugene D. C. Bayne and Lawrence A. Subers, of the Bayne- 

 Subers Tire and Rubber Co., of Cleveland, Ohio. In the illus- 



F.\BRIC M.\KING M.VCHINE FOR TiRES AND HoSE. 



trations herewith one shows the fabric-making machine which is, 

 in brief,, a movable table made up of a wide endless metal band 

 that runs longitudinally over two large drums. Mounted upon 

 this is a movable carriage that runs transversely over the band. 

 The machine is fitted with the necessary gears, guide wheels, 

 and the like, and is run by power. The 

 second illustration shows the fabric 

 produced by the machine. This fabric 

 is composed of layers of threads, each 

 strand being coated with rubber; the 

 strands then being laid parallel so that the 

 rubber surfaces touch and join, and 

 when one longitudinal layer is finished 

 a transverse layer is built upon it, the 

 ^•whole being then vulcanized. It is said under tests that the fabric 

 shows wonderful strength. The patents are numbered 885,220 



;and 885,219, respectively, and dated April 21, 1908.

under pressure to the chambered end of the plunger which 

 spreads outwardly the inner tube of the hose across the end 

 of the knife. The invention is covered by patent No. 885,797, 

 issued April 28, 1908, to Samuel J. Sill, assignor of one-half to 

 Herbert H. Hewitt, both of Buffalo, New York. 



A SHOE CEMENTING MACHINE. 



In the manufacture of certain types of footwear cementing 

 machines are coming more and more into use. Indeed, their 

 application extends even further than 

 the industry mentioned. In the illus- 

 tration accompanying this is a simple 

 type of cementing machine which 

 comprises the usual reservoir and 

 trough, through which the material to 

 be cemented is led, feed opening 

 ducts, etc., the whole arranged so that 

 the supply of cement can be in- 

 creased, diminished, or shut off al- 

 most instantly. This invention is cov- 

 Cementing Apparatus, cred by United States patent No. 885,- 

 862, issued April 28, 1908, to Charles W. Phipps and William 

 J. Steele, of Northampton, England. 



A New Baling Press. 



fUsed for baling scrap rubber and in some rubber factories for baling 

 waste paper and pasteboard. Manufactured by the Sullivan Machinery Co., 

 Clareinont, New Hampshire.]
