COMBINATION OF RUBBER AND METAL 



LETTERS patent issued at Washington (No. 793,181 — June 

 27, 1905) relate to a composition of matter, whereby rub- 

 ber is combined with fibers of metallic wool and the whole vul- 

 canized. The object is to secure greater durability in tire 

 treads, boot heels, and other articles in which resistance to 

 wear is desirable, while retaining the elasticity and pliability of 

 rubber. The proportions of rubber and metallic fiber may be 

 varied, according to whether the composition is required for 

 heels, tires, or other uses; the metallic fibers may be distrib- 

 uted uniformly through the mass, or so arranged as to form 

 layers embedded in the rubber. The latter arrangement is re- 

 ferred to as particularly desirable in pneumatic tires, as a pro- 

 tection against puncturing. 



One method of effecting the combination is by placing the 

 metallic fibers in a mold and pouring rubber solution over 

 them. Although the article known commercially as "steel 

 wool " is at present the only commercial commodity which the 

 patentee finds feasible for carrying out his invention, he does 

 not limit his claim to that specific material, inasmuch as any 

 metallic elongated fiber will answer the purpose so long as it 

 possesses the qualities of tensile strength and elasticity and is 

 of a crumpled character or form like the fibers of steel wool. 

 The inventor is James P. Crane, Chicago manager of the 

 Franklin Life Insurance Co. 



[Mineral cotton is a fiber formed by allowing a jet of steam 

 to escape through a stream of liquid slag by which the slag is 

 blown into fine white thread. It is a poor conductor of heat 

 and is, therefore, suggested as a covering for steam boilers and 

 pipes. A variety with short fiber is called mineral wool and is 

 used as a non conductor of heat, or a deafening for floors.] 



FORM FOR SEAMLESS RUBBER GOODS. 



IN the specification of United States patent No. 791,774, re- 

 lating to a form for making seamless rubber articles, the 

 inventor, Thomas M. Gregory (Akron, Ohio), refers to the lia- 

 bility of hot water bottles, syringe bags, and the like to develop 

 leaks where the edges of the parts constituting the articles are 

 joined together to complete the manufacture. The object of 

 the new invention, therefore, is to provide forms for the manu- 

 facture of hollow rubber articles by dipping into rubber solu- 

 tion, which forms may be removed after the completion of the 

 bottle or bag, leaving the latter entirely without seams and 

 therefore of equal strength at every point. Such removal of 

 the form requires its destruction, so that only a single use of 

 the form is possible; but the invention does not require ex- 

 pensive material or expensive labor in the manufacture of the 

 form, and a paper pulp or a suitable grade of paper stretched 

 upon an edging or border frame, say of laminated paper glued 

 together and thus made temporarily rigid, will sufiice, though 

 the inventor does not limit himself to any special material or 

 manner of getting the same out of the bottle or bag. The 

 patentee refers to the use of shellac on the outer surface of the 

 paper form, or other treatment, to give a smooth finish which 

 the rubber cement does not penetrate and upon which it will 

 adhere and make an even unbroken deposit. 



When Will That Be ?— The Durango Detnocrat says that 

 the Rocky Mountain Crude Rubber and Developmeut Co. is a 

 fake. It is to be supposed that when this company, which is 

 composed of some of Salida's representative men, begin to turn 

 out the crude rubber the editor of the /^<f/«(;fra/ will be con- 

 vinced that it is not a fake. — Salida (Colorado) Record, May 26
