PLACING CROSS WIRES IN TIRES. 



THE accompanying drawing shows a machine for inserting 

 the cross wires in the bases of solid tires. The machine 

 performs this operation on the finished tire of annular 

 form, after vulcanizing. The tire is placed on a drum A hav- 

 ing a ratchet in one edge so that it can he advanced step by step. 

 This drum is mounted on a turn table B so that the tire can be 

 turned to permit of inserting the wires at any angle to the base 

 of the tire. With the tire in position and held down by a roller 

 C, the treadle D is pushed down by the operator, engaging a 

 clutch on the driving shaft E and causing a drill F to advance 

 and bore a hole through the tire. When the drill is withdrawn, 

 the wire G is gripped by a cam // and the end pushed forward 

 into the hole in the tire. The wire is then cut off the proper 

 length by a shear /, and the end projecting from the tire is 

 pushed into place by a hammer automatically operated. The 

 wire is straightened as it is drawn from the supply wheel by 



and /, where it 

 is sheeted, and 

 stamped with 

 any design or 

 wording which 

 may be en- 

 graved on the 

 smaller roller.

NORZAGARAY'S EXTRACTOR AND WASHER. 



A XOTHER interesting machine just patented in this country 



■**■ is an extracting and washing machine designed by Nor- 

 zagaray and illustrated by the accompanying drawing. The ma- 

 chine is designed for cleansing crude rubber, as well as for 

 kneading and rolling it into sheets. The rubber is fed contin- 

 uously into the top of a conical tube A and is forced down by 

 the conveyor screw />' until il passes out at the lower end of the 

 tube. Hot water is kept running over the rubber from a tap C 

 and from a perforated pipe D at the top of the tank E. Formed 

 on the inside of this tank are spiral threads F, which engage 

 spiral ribs G on a cylinder rotating in the tank. The rubber 

 emerging from the lower end of the tube A is forced upward 

 by these spiral ribs and thoroughly masticated while the hot wa- 

 ter is continuously running over it. The mass of rubber emerges 

 at the top of the tank and is passed between vertical rollers // 



The following are brief extracts from the 

 specifications of other interesting United States 

 patents recently granted. 



PULVERIZES FOE SCRAP RUBBER. 



Xo. 1,102,789, July 7, 1914. Joseph Ogden, 

 Manchester, England. A machine for grinding 

 or pulverizing scrap rubber. The rubber is fed 

 into a cylindrical hopper and comes in contact 

 with a rapidly revolving disc having an abrasive 

 surface or sharp cutting edges in the form of 

 spirals. 



METALLIC STOCK SHELL. 



No. 1,104,296, July 21, 1914. William F. Gam- 

 meter, Cadiz, Ohio. Metallic stock shell for winding up sheeted 

 rubber or coated fabric as it comes from the calender. This roll 

 is entirely of metal and is designed to facilitate cooling. It is 

 an improvement on patent No. 1,003,593 of 1911. 



LAST MAKING MACHINE. 



No. 1,104,040, July 21, 1914. E. A. Eastman, assignor to the 

 Crawford McGregor & Canby Co., Dayton, Ohio. Automatic 

 machine for turning shoe lasts. It is interesting to note that, 

 although the patent just granted covers minor improvements, 

 the original of this machine was illustrated and described in 

 The India Rubber World of May, 1904. 



JAR RING AND GASKET LATHE. 



No. 1,107,404, August 18, 1914. F. Brelle, Sr., and F. Brelle. 

 Jr.. l-'erndale, California. A machine for cutting rubber gaskets 

 or jar rings, wherein the rubber tube is placed on a revolving 

 spindle and the cutter is automatically fed forward and ad- 

 vanced toward the tube. The knife may be adapted for cutting 

 rings with a curvature in cross-section of almost 90 degrees. 



DENTAL VULCANIZER. 



No. 1,107,441, August 18, 1914. N. W. Olson, Galesburg. 

 Illinois. A vulcanizer for curing dental goods, opened and
