THE INDIA RUBBER WORLD 



[Ai'RiL 1, 1919. 



The frames of the machine are of channel-shaped cast iron 

 and rigidly supported by four tie-rods. The cast-iron spiders, 

 riveted to each end of the barrel, are provided with journals 

 that support the barrel in the side-frame bearings. The joints 

 in the head of the barrel are riveted, and all joints and seams 

 are soldered inside and outside as a prevention against leakage. 

 The body of the barrel is constructed from triangular, galvanized- 

 iron plates that churn the contents from side to side when the 

 barrel rotates. A brass filler cap, with a lip on each side and a 

 quick-opening clamp attachment, enables the operator to draw- 

 off the cement from the top, free from settlings. The machine 

 is furnished with tighl-and-loose pulleys and built according to 

 the required capacity. (The Roy D. Quin Co., Willoughby, 



Ohio.) 



THE "WESTERN" RETREADING MACHINE. 



The growing interest in rebuilt tires has greatly stimulated 



the builders of retreading equipment in improving the design of 



repair vulcanizers. It 



is claimed that the new 

 machine here illus- 

 trated will produce va- 

 rious non-skid tread 

 designs, including the 

 Silvertown ribbed 

 tread. A new feature 

 is the multiple-spring 

 pressure plate and 

 centering blocks that 

 effect an even distribu- 

 tion of the curing pres- 

 sure. 



Tliere are two molds 

 to a complete outfit, re- 

 treading tires from 28 

 The "Western" Retreader. by 3 to 37 by 5. The 



equipment furnished with each set consists of six lever clamps, 

 two multiple-leaf pressure springs, two sand-bags, one clamp- 

 lever, one matrix bolt-wrench, one ratchet wrench, six centering 

 blocks, four disk globe-valves, and all pipe fittings, etc., ready 

 to connect to steam line. (Western Tire & Rubber Works, 

 321-323 North Crawford avenue, Chicago, Illinois.)

MACHINE FOR APPLYING BEAD-CLAMPING RINGS. 



BEAD-clamping rings used when curing tires on expansible 

 cores or air bags, are quickly and accurately drawn into 

 place by this machine. The figure is a vertical section through 

 the center of the ap- 

 paratus that consists of 

 a circular table mounted 

 on three legs at a con- 

 venient height for han- 

 dling the tires. Mounted 

 in the center of the table 

 is a vertical screw, A, 

 provided with a threaded 

 nut and a collar, to 

 which three links, B, are 

 attached and adjustably 

 connected to slides that 

 terminate in vertical 

 ^ ,, guides, C. A piston 

 BE.^n-R,NG Clamping Machine. ^^^ip,„,,ji„g ;„ ,^^ 



cylinder, D, supports on its upper end a head with three 

 arms £, to which are pivoted vertical arms terminating in hooks 

 F. Pivotally connected to the arms are links G terminating in 

 spring slides that operate with the piston to control the clamp- 

 ing hooks. 



Lower bead ring H is placed on the table by the operator 

 and centered by guides E, when a tire containing an air bag is 

 placed upon it and the upper bead ring / superposed. Air is 

 admitted to the bag, meanwhile fluid pressure is admitted to 

 the cylinder D whereby the hooks C engage the tongue of the 

 upper head ring, thus drawing both rings together. When 

 sufficient pressure has been forced into the air bag to properly 

 seat the bag and the lower edges of the tire in the rings, the 

 pressure is relieved and the piston forces the rings downward- 

 ly to the final position where they are secured by bolts through 

 the tongues of the clamping rings. The piston is then forced in 

 the opposite direction and the tire with the clamping rings is 

 ready to be placed in the mold. (William C. Stevens, assignor 

 to the Firestone Tire & Rubber Co., both of Akron, Ohio.
