destructive in some forms of manufacture. 

 The canvas tire is practically noiseless, 

 which means greater comfort in cases 

 of hospitals and the like and greater pro- 

 duction in factories by the decrease of 

 distracting noises. It is not affected by 

 water, oil or grease and as a result is used 

 on kitchen, laundry and packing-house 

 equipment.

The canvas tire is less de- 

 structive to concrete factory 

 floors, linoleum runways, etc., 

 and is practically noiseless 



This improved tire is made 

 up of layers of canvas bound 

 together, and may be fitted 

 with a roller bearing as shown 



Canvas Wheels Reduce 

 Noise and Save Floors 



WE have steel tires, pneumatic tires 

 and solid rubber tires, each with 

 its place on some sort of vehicle, but the 

 latest is a canvas tire designed for fac- 

 tory trucks, hand trucks, electric indus- 

 trial vehicles and other portable objects 

 such as hospital beds, 

 operating tables, oil 

 and gasoline tanks 

 and a score of other 

 devices. Less resili- 

 ent and less costly 

 than rubber, the can- 

 vas tire is far more 

 re.silient than iron or 

 steel and of equal 

 wearing qualities. 



The canvas tire 

 finds its greatest field 

 on vehicles which are 

 either slow or which 

 do not travel far. 

 It is far less destruc- 

 tive to concrete fac- 

 tory floors, linoleum 

 runways, etc., than 

 metal tires and does 

 not wear away con- 

 crete and produce the 

 fine dust which is so 



Tire Repairing Made Easy 

 with a New Spreader 



N accessory designed to 

 make easier and lighter 

 the work of repairing 

 automobile tires has re- 

 cently been put on the 

 market. It consists essen- 

 tially of two parts — a buffer 

 plate and a working stand 

 on which the tire cover is 

 held. The buffer plate, 

 which is convex, is applied 

 to the outside of the cover 

 at the place where it is 

 desired to make the repair, 

 and is held in place by a clamp. Thus 

 the cover is pulled back and the operator 

 is able to reach the canvas. The cover 

 is then placed on the stand, as shown 

 in our illustration, with the buffer plate 



next the stand.

The work of Automobile tire repair- 

 ing is made easy with this machine 



It is held in place by 

 two claws that en- 

 gage the beads of the 

 cover and hold it 

 firmly. The stand 

 has four small rollers 

 on its saddle which 

 can be raised to bear 

 the weight of the 

 cover, enabling it to 

 be easily rotated for 

 examination, or which 

 can be retracted level 

 with the saddle while 

 the cover is being 

 worked on. The ma- 

 chine weighs about 

 sixty pounds. The 

 fabric can be cleaned 

 with a buffer wheel 

 in a very short time, 

 instead of by the old 

 laborious method of 

 scrubbing with gaso- 

 line.
