STEAM BAG FOR TIRE REPAIR 

 The "Perpetual" steam hag permits the application of heal 

 to the inside as well as the outside of the tire during repair 

 vulcanization It is. made of two sections of inner tubing pro- 



t e c t e d by a 

 stockinette cov- 

 i- r i n g. All 

 metal parts, 

 such as caps, 

 are of cold 

 rolled steel, 



and the littings are standard Schrader connections and valves for 

 use with steam. The construction of the head of the bag allows 

 drainage of all condensation. Every pound of steam gives results, 

 as the expansion of the bag makes it adjust itself to the exact 

 shape of the inside of the casing. Connection is made to fit all 

 molds so that it can he used with any equipment. It is made in 

 i'/j, 4, AVz, 5, 6, 7, and 8-inch sizes. — Perpetual .Air Bag Co.,

THE SIVYER STEEL TRUCK WHEEL FOR PNEUMATICS 



.■\ cast steel wheel for pneumatic-tired trucks has been developed 

 in a distinctive variation of the disk type. The metal is refined 

 heat-treated steel, and the hubs are cast integrally with the 

 wheels. Four triangular-shaped openings in the web serve to 

 lighten the wheel and improve its appearance. One of these open- 

 ings is located over the valve slot which permits of using the 

 standard valve stem and the extra clearance allows room for 

 any standard air-line connection when pumping the tire. The 

 valve slot is opened through the outside edge of tlie wheel, per- 

 mitting easy mounting or demounting the demountable rim. The 

 rim is channel section, reinforced by cross braces, 



Special attention has been paid to eliminate any features of 

 design which would cause strains to be set up during the casting 

 process. The result is an efficient-looking wheel, combining 

 strength with Tght weight.— The Sivyer Steel Casting Co., Mil- 

 waukee, Wisconsin. 



A NON-SKID ABRASIVE TIRE TREAD 



A new non-skid tire, called the "Bearfoot," is being made in the 

 recently opened factory of the Hobson Rubber Co., 102S South 

 Hill street, Los Angeles. Instead of using knobs, designs, and 

 corrugations on the surface of the tread, as many manufacturers 

 do in order to lessen the area of rubber on a slippery surface, or 

 to get more or less of a vacuum grip on the road surface, the 

 Hobson concern increases the coefficient of friction by incorporat- 

 ing a large quantity of abrasive material (finely graded sand) in 

 the body of the tread. As the tread wears, the hard particles in 

 it produce a surface not unlike sandpaper, which, it is claimed, 

 securely grips the wettest or oiliest asphalt by presenting innumer- 

 able minute angles of tread that fit into the cinintless tiny depres- 

 sions in the smooth road surface. The tread is built in layers 

 much like camelback. Bearfoot retreads are also made in the 

 same factory with a standard guarantee to retain non-skid quali- 

 ties for 5,000 miles. A patent has been applied for on the process 

 by which the abrasive material is distributed in the rubber so as 

 fot to cut the latter.
