PROCESS PATENTS. 



PROCESS OF MAKING HEELS OR SOLES FROM SOLID TIRE SCRAP. 



THE utilization of rubber scrap, such as solid tires, in the man- 

 ufacture of rubber heels or soles and without further reclaim- 

 ing, is the object of the present invention. The tires are first cut 



into convenient 

 lengths and 

 clamped in a 

 holder with the 

 base portion 

 e.xposed. This 

 rough surface 

 is ground off 

 by an abrasive 

 wheel, when 

 the tire section 

 is removed and 

 placed in an- 

 other holding 

 device operat- 

 ing in connec- 

 tion with a band saw that divides the tire longitudinally into slabs 

 of suitalde thickness. These flat strips are then dehvered to the 

 machine shown in side elevation and plan in the accompanying 

 illustration. An endless conveyor belt A, moved intermittently 

 by the ratchet wheel and hand lever shown on the right, carries 

 the stock under a treadle-operated die press B that punches out 

 the heel blank, but leaves it within the slab. As the slab ad- 

 vances each heel blank is branded with a heated die as it passes 

 under the device shown at C, and the nail holes are finally 



drilled by the muUiple drill D, when the finished heels are carried 

 from the machine by the conveyor belt. The periodic movement 

 of this conveyor belt is obtained by a hand lever ; the punching, 

 branding and drilling operations are performed in unison by a 

 foot treadle, while the drills arc driven by a small electric motor.

 A. Templeton, Detroit — both in Michigan. United States patent 

 Xo. 1,230,510.] 



Porous Rubber Fabric. Open mesh fabric is coated and par- 

 tially impregnated with rubber solution, after which the coating 

 is perforated at the interstices by fluid pressure, the solvent 

 evaporated and the rubber vulcanized. [Arthur B. Kempel.

 of New York. United States patent No. 1,229.284.]

MISCELLANEOUS PATENTS. 



FRENCH RUBBER CUSHIONED WHEEL. 



HIS is a wheel of the disk type that is evidently designed for 

 military motor trucks, wagons and gun carriages. Referring 

 to the illustrations, the wheel comprises a metal tire A that may 

 be rubber shod, two side 

 plates or disks B and two 

 star-shaped pieces C that 

 hold the four rubber cush- 

 ions D and the rubber hub 

 E in place. Metal rings 

 encircle the four outer 

 rubber cushions that are 

 held in place by the two 

 star-shaped pieces and four compression bolts. The rubber hub 

 cushion is also provided with an outer metal band and is sup- 

 ported on the axle of the wheel by a metallic sleeve through 

 which the a.xle bolt passes. [G. Constani. French patent No. 

 482,308.] 



The afifairs of the defunct Northland Rubber Co. were closed 

 in the Supreme Court on July 17, when Justice Sears confirmed 

 the receiver's report by which the creditors of the company will 

 realize about 70 cents on the dollar, while the stockholders will 

 sufifer a total loss according to statements made to the court. 

 The plant was recently sold to the Kelly-Springfield Tire Co. 

 for $270,000. 



The Scioto Rubber Co., of Columbus, Ohio, has filed a damage 

 claim against that city for $24,500 based on the grade elevation 

 of the railroad tracks at East Fifth avenue which has practically 

 shut off means of access to the company's plant. 



The Porter Rubber Co., Salem, Ohio, recently voted to sell 

 $110,000 of its treasury stocks. Funds realized will be devoted 

 to an increase of capacity, the present output being 100 tires daily.
