THE INDIA RUBBER WORLD 





L. A. SUBERS AND HIS FABRICS. 



THE fabrics are descriptivelj known as "laminated, cohesive, 

 interwound" and are the results of many years of work 

 on tlu' part -of the inventor. First perhaps a word as to tins 

 same inventor. He is L. V Subei ol Cleveland, Ohio, where 

 lie was born in 1865. Educated in public and private schools, 

 he studied mechanical engineering under his father, who was 



L. A. Subers. 



an architect and builder and identified with the manufacture of 

 machinery. He became interested at an early aye in the de- 

 velopment of new inventions, taking out his first patent in 1886. 



He also studied corporation and patent law for the purpose 

 of fully familiarizing himself with the establishment of industrial 

 corporations, and also for the purpose of protecting his in- 

 \ entions. 



Then, after having been identified with various corporations, 

 he seriously took up the development of his new fabrics for the 

 manufacture of a certain line of rubber products. For seven 

 years he experimented and patented. Some 30 patents are soon 

 to appear here and abroad covering this particular series of 

 fabrics, machinery, processes and devices, in the most important 

 •countries of the world. 



Mr. Subers has been so long in the atmosphere of the great 

 American patent that he unwittingly talks its language. For 

 example, in describing his fabrics he says 



"The primary principle upon which my fabric is built is based 

 upon a laminated, cohesive, interwound principle which natu- 

 rally is of a tubular form, consisting of yarn elements in 

 numerals. 



"That is to say, ordinarily I may use 2,1-1 cotton from 12 to 

 18 ends up, 16 of these spools constituting the principle of 

 lamination. In other words, take 23-1-14 ends up as an ex- 

 ample; sixteen spools, 14 ends on a spool, would be 224 yarns, 

 making a band of tubular form collapsed, thereby having selvage 

 edges, said yarn elements being laid at a predetermined angle 

 to the axis of the mandrel, usually being 2J-4 inches or more. 

 The angle at which these yarns are laid or incorporated deter- 

 mines to a g.eat extent the extensibility of the finished tubular, 

 collapsed band. 



"Some of the fabric is made from 37-1-25 ends up, thereby 

 having a total of 400 yarns in the finished band, the band aver- 

 aging from y 2 inch to 54 hich in width, and of a thickness aver- 

 aging 3/64 inch and up. In the construction of this band I 



utilize rubber compound or cement, or any other suitabli id 

 hesive, depending on the purpose for which the same is intended, 

 and at the same time I incorporate among said yarn elements 

 ribbon hands of rubber, so that when the entire product. 

 sisting of rubber in the form designated and the yarn elements, 

 is finished, the hand of the character described is the result. 



"In building tire fabrics ami hose of various diameters 1 am 

 able by the angle at which these yarn elements are laid m the 

 hand, and also by the predetermined amount of stretch that is 

 taken out of the hand itseli before being incorporated into a 

 fabric, to control under pressure to a minimum the elongation, 

 contraction, expansion, twisting and writhing conditions which 

 now exist under the old method of constructing like articles 



of manufacture 



' * I li.it is I" say, 1 can control my fabric to a minimum by the 

 use of the same cotton and the same rubber as is now in VOgUi 

 bj the old method of loom weave, braiding, etc. By no pro 

 of distributing the rubber through a large number of yarns, I 

 obtain results heretofore unknown in the art of manufacture 

 of rubber g Is oi a specific character. 



"As an example, the railroad officials have a machine that is 

 called a pounding machine to test air hrake hose. Under my 

 principle of constructing air brake hose, the difference in re- 

 sults is as follows: Most any make of air hrake hose on the 

 market today, under this severe test, will pound through the rub- 

 be! and fabric at from live to fifteen blows. In the same thick- 

 ness of hose, and primarily the same composition of rubber and 

 cotton, my hose will stand not less than fifty blows. 



"In all my hose tests I obtained practically one-third more 

 bursting pressure than any hose tested, in comparison with 

 what I have been able to laid." 



The India Rubber World has been in touch with the Subers 

 laboratories for a number of years and has seen some wonderful 

 strength tests in hose and other fabrics. At the present time 

 the Goodyear Tire & Rubber Co., of Akron, has been licensed 

 to use the Subers machines on lease. If we understand Mr. 

 Subers' late communications aright, other companies will be 

 granted licenses, the machines being built and owned by the 

 patentees, The Subers Fabric & Rubber Co. 



TRADE NEWS NOTES. 



The Marathon Tire & Rubber Co., of Cuyahoga Falls, Ohio, 

 has under way a new addition to its tire manufacturing plant. 



The new list of the Fisk Rubber Co., which went into effect 

 January 1, cpiotes reduced prices on white non-skid casings and 

 gray tubes, and announces the addition to the line of the Fisk 

 non-skid "Red Top" tire and red tubes, an attractive new propo- 

 sition at approximately the old prices. 



The McGraw Tire & Rubber Co., of East Palestine, Ohio, has 

 opened a branch at 667-9 Boylston street, Boston, in the building 

 formerly occupied by the Diamond Rubber Co. Wallace G. Page, 

 for several years general manager of the tire department of the 

 Hood Rubber Co., is manager of this new branch. 



The John H. Parker Co., of Maiden, Massachusetts, is calling 

 the special attention of the drug store trade to his bathing shoe 

 proposition. The chief line of this company, which started in 

 1865, is rubber boots with leather soles, but it has specialized 

 for many years in bathing shoes and is now producing an ex- 

 tensive and attractive line. 



United States imports of chicle amounted in November last 

 to 435,000 pounds, almost double those of the previous November, 

 which totaled 223,000 pounds. 



"Rubber and Its Manufacture" was the subject of an address 

 by Frank H. Van Derbeck, of the Hewitt Rubber Co., of 

 Buffalo, New York, at the meeting of the Society of Chem- 

 ical Industry on December 14 at Cleveland, Ohio.
