THE INDIA RUBBER WORLD 



[June 1, 1917. 



The present invention enables the production of a seamless, 

 molded glove, the thumb being positioned opposite the forefinger 

 with a space intervening, and one that is reinforced where 

 strength and thickness are desired. 



The mold, consisting of four parts. A, B, C and D, is shown 

 in the illustration. A and B are the lower and upper mold 



■p Jt, 



parts and C is the core. D is the part that occupies the space 

 between the thumb and forefinger, the upper face forming the 

 index and a portion of the middle finger, while the opposite face, 

 shown at E, forms the balance of the thumb. Six pieces, destined 

 to form the various parts of the glove, are cut from calendered 

 stock and placed in their respective positions in the mold, which 

 is then assembled and subjected to heat and pressure in a vul- 

 canizing press. [Richard T. Griffith, assignor to The Miller

DEIVIKG CLUTCH FOR MILL HOLLS. 



Usually the large driving gear of mills and grinders is at- 

 tached to the back roll and driven from a clutch-controlled pinion 

 kejed to the main driving shaft. According to the present in- 

 vention the large gear 

 shown in the illustration 

 at A, rotates loosely on 

 the roll. Keyed to the 

 end of the roll is a 

 clutch drum surrounded 

 by a heavy spring coil B, 

 that grips or releases the 

 drum. The clutch ac- 

 tuating mechanism com- 

 prises a sliding collar C, provided with two oppositely placed 

 arms carrying a guide pin and a clutch operating pin that is 

 pivoted to the arms of a bell-crank lever attached to the hub 

 of the large gear. A split ring D surrounds the collar and is 

 connected by two arms to a rock shaft E. A vertical arm at- 

 tached to the rock shaft supports at its upper end a threaded 

 rod on which a combined nut and hand wheel F is mounted. 

 When this is rotated in the proper direction the nut contacts 

 with the vertical arm, thereby rocking the shaft, and the sliding 

 collar operating the bell-crank connections tightens the coil 

 clutch on the drum and connects the driver to the shaft. When 

 the hand wheel is rotated in the opposite direction, the vertical 

 lever is released, the collar slides back, aided by spring action, 

 the coil frees itself from the drum and the machine stops. It 

 is also equipped with a safety stop device whereby the machine 

 may be instantly stopped by the operating rod that is arranged 

 above the roll within reach of the operator. [David R. Bowen, 

 assignor to Farrel Foundry & Machine Co. — both of Ansonia, 

 Connecticut. United States patent No. 1,225,309.] 



BUBBER SHOE TARNISHING MACHINE. 



This machine comprises an endless chain conveyor that car- 

 ries the lasted shoes past a series of nozzles from which shoe 

 varnish is discharged, covering the shoes with a coat of varnish. 

 The illustration is a 

 transverse section of the 

 machine at the point 

 where the varnish is 

 applied. 



In operation tlie suc- 

 cessive sticks of shoes 

 are placed in the trav- 

 eling holders and carried 

 between the nozzles A, 

 B and C, that direct a 

 flow of varnish against 

 the shoes as they pass 

 in succession. The sur- 

 plus varnish drains into 

 the trough D and flows 

 by gravity to the receiv- 

 ing tank E, from which 



it is continuously supplied to the discharge nozzles by the 

 pump F. The machine is of sufficient length so that the sur- 

 plus varnish will drip from the shoes into the trough. It may 

 be so constructed that the sticks of varnished shoes can be 

 taken from the machine and placed directly on the racks of 

 the vulcanizing heater. [Le Baron C. Colt, assignor to National 

 India Rubber Co. — both of Bristol, Rhode Island. United States 

 patent No. 1,225,013.]

MACHINE FOR WINDING GOLF BALL CORES. 



Elastic thread is wound in different great circles around the 

 core, at the same time being evenly distributed over the entire 

 body of the ball by the automatic action of the machine here 



shown. The upper illus- 

 tration is a side eleva- 

 tion and the lower view 

 is a plan of the rnachine. 

 The two side frames A, 

 support the mainshaft B, 

 that is provided with a 

 hand wheel and belt 

 drive. Pivoted on this 

 shaft are two horizontal 

 arms C and D that sup- 

 port the ll e a ri n g E, 

 through which pass a 

 tubular and a solid 

 shaft. Directly under 

 the upper bearing is a 

 similar bearing bolted to 

 the frame and through 

 which pass tubular and 

 solid shafts similar to 

 those in the upper bear- 

 ing. The spur gear F, 

 fixed to the main shaft, 

 meshes with two sets of 

 pinions of different pitch, 

 being keyed to the upper tubular and solid shafts, respectively, 

 while the other two pinions are keyed to the lower tubular and 

 solid shafts. On the opposite ends of the upper shafts are two 

 knurled disks H, and similar disks / are attached to the corre- 

 sponding ends of the lower shafts. Due to the different pitch 

 of the driving pinions the inside upper disk revolves at the same 

 speed as the lower outside disk, and the upper outside disk re- 

 volves at the same speed as the lower inside disk, the former
