���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.

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

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.
