of the rubber sheet by heat and pressure of the roller against 

 the edges of the form. After the form has passed beyond the 

 roller F the reinforced boot top is removed by the operator. 

 The scrap pieces are stripped from the drum by the action of 

 belt (7, which delivers them to the hopper under the machine. 

 [E. B. Herman, East Watertown, Massachusetts, United States 

 patent No. 1,173,426.] 



Solid Tire Drilling M.\chi.ne. Solid and cushion tires 

 may be drilled on this machine, to accommodate cross wires 

 that engage the side wires holding the tire to the rim. [William 

 C. Stevens, assignor to Firestone Tire & Rubber Co. — l)oth of 

 Akron, Ohio. United States patent No. 1,171,552.] 



Tire Bead Centering Device. This consists of a ring provided 

 with an annular recess conforming to the contour of the finished 

 bead. The ring is centered by three shouldered brackets or arms 

 which slide within the inner circumference of the core. When 

 the ring is revolved the bead is laid on the casing and accurately 

 centered with relation to the tire. The other bead is applied in 

 the same way. [John R. Gammeter, .\kron, Ohio, assignor to 

 The B. F. Goodrich Co., New York City, United States patent 

 No. 1,164,804.] 



Method of Making a Cord Carcass for Pneumatic Tires. 

 Two layers of rubberized cord are laid spirally on the core, at a 

 reverse angle", forming the carcass. Tliis is slit around the inner 

 circumference and the bead cores interposed between the open 

 plies. The core is then removed from the winding machine and 

 a section ring attached to the inner periphery of the core, sup- 

 porting the beads. The casing and tread are then built up, the 

 two side rings for molding the beads applied and the whole wrap- 

 ped and vulcanized by the open cure process. [Walter R. Den- 

 man, assignor to Miller Rubber Co. — both of Akron, Ohio. 

 United States patent No. 1,172,115.] 



Mandrel for Making Inner Tubes. This invention com- 

 prises a mandrel provided with a depression for receiving ma- 

 terials for the valve patch which is made homogeneous with the 

 tube. [Charles E. Foutts, East Liverpool, Ohio, United States 

 patent No. 1,173,944.] 



Footwear Repairing Outfit. — .A new arrangement for repair- 

 ing rubber footwear consists of a portable vise upon the anvil 

 of which the shoe is placed, with the portion to be repaired up- 

 permost. If the sole is to be renewed, a piece of rubber is 

 placed over the old sole, and upon this is clamped a sheet of 

 lead with any desired surface configuration, and having a pro- 

 jecting flange. This is hammered down against the edges of the 

 sole or heel piece, thus giving a rolled edge similar to that of 

 a new shoe. Then the shoe is removed from the vise, and 

 after the parts are clamped in any suitable holder it is vulcan- 

 ized. The result is a finished sole or heel substantially equal to 

 that of a new shoe in neatness and finish. [James W. Arthur, 

 Warren, Ohio. United States Patent No. 1,174,799.] 



Hydraulic Tire Vulcanizing Mold and Press. — The object 

 of this apparatus is to partially vulcanize the tire cover before 

 the curing operation which gives the tire its final shape. This 

 relates more particularly to those having beaded edges, which 

 are not rigid in the uncured condition. [Colin Macbeth of Bir- 

 mingham, England, assignor to The Dunlop Rubber Co., Limited, 

 Westminster, England. United States patent No. 1,174,885.] 



A complete description of this machine was given in The 

 India Rubber World, December 1, 1915. page 122, British patent 

 No. 11,732 (1914).

NEW MANUFACTURING PROCESSES. 



THE UNITED STATES. 



Manufacture of Heels. Scrapped solid tires are cut trans- 

 versely and made into heel blanks which are built up and formed 

 into finished heels provided with washers and nail holes by heat 

 and presseure. [U. S. Patent No. 1,172,919. Henry C. Weber, 

 Port Jefferson, New York.] 



Molding and Vulcanizing Tires. Pneumatic tires are molded 

 on a core in a sectional mold. The tread portion is removed 

 radially, while the sides and edges of the tire are stretched in a 

 direction away from the tread. The tire is subsequently removed 

 from the mold and vulcanized in any suitable manner. [United 

 States patent No. 1,166,326. J. H. Coffey and J. H. Coffey, Jr., 

 Ontario, Canada, assignors of one-half to Gutta Percha Rubber, 

 Limited, Toronto, Canada.] 



Uniting Hard Rubber and Metal. Hard rubber and a 

 threaded metal member are united by heating the former and 

 screwing the latter into an opening in the heated hard rubber, 

 which is then allowed to cool. [United States patent No. 1,165,680. 

 George C. Knauff, Chicago, Illinois.] 



Utilizing Waste Rubber. Soles and heels of footwear are 

 made by disintegrating unvulcanized scrap, and subjecting this 

 material to pressure and vulcanization. [British patent No. 

 21,445. G. W. Beldam, Ealing, and A. U. B. Ryall, Brentford, 

 both in Middlesex.]
