MOTOR DRIVEN TIRE TESTING MACHINE. 



THIS motor-driven tire tester is of the latest design. It is ar- 

 ranged to drive the tires while running against rough sur- 

 faced wheels that are provided with cross strips to simulate 

 the conditions ciicounlercd on the road. It is equipped with a 



specdom e t e r 



Tkster. 



oLU. to give the same weight as on the rear wheels. 



The bearings on the wheel shaft are roller bearing type, lu- 

 bricated with compression grease cups. This machine is built 

 to test 34 by 4-inch tires and is euipped with a IVz h. p. motor.

HIGH PRESSURE TIRE RETREADER. 



This self-contained sectional tire vulcanizer is designed for 

 effective duty and provided with a large factor of safety. The 

 boiler shell is 54-inch thick and the crown sheet is 5/16 thick and 

 contains six 1-inch tubes. All boilers are tested to 220 pounds 

 hydraulic pressure 

 and given a thorough 

 steam test before being 

 shipped. Two types of 

 burners are supplied, a 

 gas burner or gasoline 

 burner that generates 

 in less than five minutes 

 and will raise 50 pounds 

 steam piessure in 35 

 minutes. 



The molds are all 

 milled in a special ma- 

 chine built for that pur- 

 pose and are very 

 smooth in finish. The 

 ribbed tread type of 

 mold being the most 

 popular. The highest 

 grade of equipment is 

 furnished with each 

 mold, including a wovei: 

 ratchet wrench. 



High-pressure retreaders are made in three sizes, type A-G 

 curing 4>4 and 5-inch tires ; B-G curing 4-inch tires ; C-G curing 

 3 and 3><-inch tires. (Zwebell Bros. Co., Milwaukee, Wis-

COMBINATION TREAD ROULER, PEELER AND APPLIER. 



This machine combines a tread roller that will not only apply 

 and roll down the built-up tread or "camelback" in one opera- 

 tion but will also peel the old tread from the tire that is to be 

 rebuilt. 



It is substantially made, having a heavy frame post on which 

 the head of the machine pivots and swings to one side while 

 applying the tire. The head of the machine is then swung 

 around in place, locked, and the pressure screws adjusted. 



As a tread roller it will apply and roll down the raw stock 

 at the same time, forcing all air away from in front and elimin- 

 ating chances of trapping it, as the pressure is put on at the 

 same time the tread comes in contact with the lire. As a tread 

 peeler it will remove the old or worn tread from a tire in a 

 short time.

TkE.AD Peeler. 



The driving power is back-geared "three to one" so that a 

 sufficient pressure can be applied in rolling down the raw stock 

 and power gained for peeling ofif the old tread. Both tread 

 peeling and tread rolling attachments have regulating springs 

 which automatically adjust the roller to the high and low places, 

 keeping an even pressure on the tread regardless of how un- 

 evenly it may be worn or how rugged the non-skid design may 

 be. ( The Western Tire & Rubber Works, 321 North Crawford 

 avenue, Chicago, 111.)
