Vulcanizing Tire Casings. The inner circumferential edges 

 of a finished casing arc brought together and held by a strip of 

 unvulcanized tape forming a tnbe. This is placed in a two-part 

 mold provided with an 'inner expanding ring that holds the 

 tire in place. Steam is admitted to the interior of the casing 

 which is then cured in a press vulcanizer of the Doughty type. 

 [F. A. Byrne, J Ludgate Hill. Birmingham, Kngland. British 

 patent No. 8,075 (1915).) 



M.\KING Tennis B.m.i.s. Inflated pla>ing l>alls are made by 

 first forming with beveled edges, hemispherical shells of semi- 

 cured stock. The edges are cemented and the parts placed in 

 :wo-part mollis that arc brought together in an atmosphere of 

 compressed air, a portion of which is entrapped within the ball. 

 The pressure of the surrounding atmosphere on the e.xterior of 

 the balls being relieved, heat is applied to the .iiolds and the 

 balls are vulcanized. [R. H. Rosenfeld, Cleveland, Ohio, and F. 

 T. Roberts. Trenton. New Jerscv. British patent Xo. 8,756 

 (191S).] 



Composite Rubber S(ii.e. This invention consists of a sole 

 with a tread portion of rubber or rubber composition and a 

 shank or rear portion of a different material having greater 

 strength and toughness than the rubl)er portion and also being 

 less expensive. [Williams-Kneeland Co., South Braintrce, Massa- 

 chusetts. British patent No. 12,818 (1915).] 



A CoMBiN.MioN Solid .\nd Pneumatic Tire. Two pneumatic 

 tubes are embedded in annular openings that are molded within 

 a solid tire near the central circumference, allowing sufficient 

 rubber between the tubes and the tread. The tubes are inserted 

 through narrow openings in the side of the tire and provided 

 with suitable air valves, while the enti.-e tire is enclosed in an 

 outer cover. [R. Bl,-<koe, 69 A, Queens Road. Bayswater. Lon- 

 don, Fjigland. British patent Xo. 16.579 C1Q15I.]

PROCESS PATENTS. 



Process of Making Mose. The inner tube or lining is made 

 on a tubing machine and semi-cured, after which a fabric ci'ver 

 is woven on a circular loom an<l placed over the tube when iri 

 a collapsed condition. The tube is then inflated, and another 

 cover put on by passing it through a tubing machine, and finall> 

 the hose is vulcanized in any suitable way. {A. T. Hopkin'. 

 Cleveland. Ohio, assignor to The Mechanical Rubber C>.. 

 Cleveland. Ohio. United States patent No. 1,190,292.] 



Process of Forming Articles from Pl.\stic Materials. Thv 

 materials are reduced to a powder and a light coating sifted 

 upon the mold which is then heated to expel the gases and 

 render the material plastic, .-\nother thin coating is sifted upon 

 the previous layer and the mold again heated. This operation 

 is repeated until the required amount of material is in the mold, 

 which is then closed and subjected to pressure, heat and finall> 

 cooled. [W. J. Burns, assignor to The Peerless Vulcanite Co.— 

 both of Bridgeport. Connecticut. Ciiited States patent N< 

 1.190,510.] 



Molding Hot Water Bottles. The parts are semi-cured in 

 a mold and then removed, stripped from the core and again 

 assembled with a T-shai)ed binder strip of quick curing stock 

 between the edges. The bottle is then placed in the mold, partly 

 inflated and fully cured with heat and pressure, producing ;. 

 seamless article. [X. D. Crawford, Elizabeth, New Jer.se.\ 

 assignor lo The Mechanical Rubi)er Co.. Cleveland, (^hir. 

 Ciiited Stales patent No. 1,190,731.] 



Solid Tires and Treads of Pneumatic Tires. These are 

 made by laying unwoven fibers side by side, forming strips, 

 one fiber thick, that are then impregnated and enveloped in 

 rubber. These strips are superimposed, forming a block from 

 which sections are stamped, built up and vulcanized in the forn-. 

 of a solid tire or shoe, with the ends of the fibers presented to , 

 the wearing surfaces. [J. W. II. Dew. London. England 

 United States patent No. 1,191,876.) 



.M.aking Elastic Leather. Soft leather is stretched, coated 

 with rubber cement and united to a piece of elastic fabric under 

 tension, .\fter the cement has dried, the tension is released 

 and the elastic fabric is stripped from the leather, leaving the 

 dried film of rubber on the leather. This is again stretched, 

 coated with cement and united to the elastic fabric a second 

 time. .After drying, the tension is released and the leather and 

 double filin are again stripped from the elastic fabric. These 

 operations are repeated until the leather has sufficient elastic 

 material in and on it for the intended purpose. [M. Scheuer. 

 assignor to Carrie Scheuer— both of New York City. Unite.! 

 States patent No. 1,192,691.] 



Process of Treating Textile Materials. The fibers are 

 carded or combed into substantially parallel lines and subjected 

 to :. vacuum to e.xpel the gases, at the .same time the materia! 

 is impregnated with rubber solution. In the manufacture of 

 tires, hose and other products from this material the fibers may 

 be laid radially, diagonally or in a combination of ways. [R. B. 

 Price, New York City, assignor to Rubber Regenerating Co.. 

 -Mishawaka, Indiana. United States patent No. 1.192.794.)
