PNEUMATIC TIRE TREAD SLICING MACHINE. 



In reclaiming scrap tires the tread is removed, prior to 

 placing the carcass in the acid baths, by slicing off the tread by 

 hand which results in uneven work and is a relatively costly 

 operation. The machine here shown in sectional elevation severs 

 the tread by action of a 

 reciprocating knife and 

 provides means for sup- 

 plying water to facili- 

 tate the cutting opera- 

 tion. 



The beads are first 

 removed and the tire is 

 fed between the rollers 

 A and B, the center 

 portion of the former 

 lieing cut away to ac- 

 commodate the bulge of 

 the tire flattened be- 

 tween the rollers. The 

 knife C reciprocates 

 horizontally but is fixed 

 vertically, consequently 

 the upper roller B must 

 be adjusted vertically 

 until the correct thick- 

 ness of the tread is 

 gaged between the knife 

 and the bottom pe- 

 riphery of the idler 

 roller B. The vertical adjustment of the lower roller A is made 

 by the hand-wheel D. 



When power is applied, the knurled portions of the lower 

 roller engage the inner surfaces of the tire side walls, drawing 

 the tire between the rollers while the reciprocating knife slices the 

 tread. .A pump supplies a continuous flow of the cutting lubri- 

 cant that collects in a sump, is strained and delivered to the 

 pump line for reuse. (Edw-ard Nail, assignor to The Goodyear 

 Tire & Rubber Co., both of .\kron, Ohio. United States patent

RUBBER-MAKERS' CRAYON. 



While it would seem at first thought that any sort of marking 

 crayon would be adaptable to rubber workers' use, it is, in 

 quite to the contrary. The fact is. a high-grade wax

crayon with unusual lasting qualities is required and one that

ACCESSORY MANFACTURERS AT THE TRACTOR SHOW. 



.Arrangements have been made with the Kansas City Tractor 

 Club whereby members of the Motor and Accessory Manufac- 

 turers' Association are to participate in the Fifth Annual Tractor 

 Show to be held in Kansas City from February 16 to 21, in- 

 clusive, 1920. Applications and diagrams will be forwarded to 

 members shortly, and indications point to a large and repre- 

 sentative number of exhibitors. 



The following are the shows sanctioned by the Motor and 

 Accessory Manufacturers' .Association : 



New York (both passenger and truck shows) Jan. 3-10. 



Chicago (both passenger and truck shows) Jan. 24-30. 



Minneapolis — January 31-February 7. 



Kansas City — February 16-21. 



Boston — March 13-20. 



This is the largest number of shows ever sanctioned by the 

 .Association for any one year. Applications for space already 

 received for the New York, Chicago and Boston shows are 

 exceeding all previous records, both in the number of exhibitors 

 and the amount of space applied for. It is expected that this 

 w-ill also hold true of the Minneapolis and Kansas City shows.
