by extra heavy fabric, the side walls of the casing are claimed 

 to be practically proof against blow-outs. [The Lancaster Tire 

 and Rubber Co., Lancaster, Ohio.] 



AN ENGLISH COMBINATION NON-SKID TIRE. 



It is a well-known fact that rubber non-slcid treads hold better 

 on dry than on wet pavements. It is equally true that steel- 

 studded treads hold better on wet than on dry pavements. 

 Therefore, the Henley 

 combination non-skid 



tread with steel studs 

 and V-shaped rubber 

 projections should hold 



well in all conditions of ^fiB^SS^^I^ V 



weather. 



This tire is built up 

 on an extra stout casing, 

 with a generous thick- 

 ness of rubber on the 

 walls and a non-skid 

 tread composed of thick 

 V-shaped blocks of solid 

 rubber and toughened steel studs. The rubber blocks act as a 

 protection to the steel studs, and also permit q^.the power be- 

 ing transmitted to the road without the sudden "spinning of the 

 rear wheels and loss of studs which so often occurs when steel 

 studs only are used. [W. T. Henley's Telegraph Works Co., 

 Limited, 18 New Union street, Moorfields, London, E. C, 

 England.] 



PtTNCTTJREPEOOF TIRES. 



It is claimed that the problem of eliminating air and still retain- 

 ing the resilient qualities of a pneumatic tire has been solved by 

 the King tubeless tire. This universal desideratum is based on 

 the unusual mechanical construction of the tire which is shown 



in the illustra- 

 tion. 



The inside 

 web and cas- 

 ing are molded 

 in one piece, 

 and are really 

 a part of the 

 tire. The web 

 is a composi- 

 tion of rubber 

 which takes the 

 place of the in- 

 ner tube in a 

 pneumatic tire. 



It carries the load and is provided with two angular braces which 

 rest directly over the bead when locked in the rim. These braces 

 form a support to the web and also prevent any lateral motion 

 of the tire, under severe loads or high speed. This web from 

 the rim up to the dai-k line shown in the cut is figured as equiv- 

 alent to 70 pounds of air in the inflated tire. Between this and 

 the tread is placed a cushion, having a resiliency equal to only 40 

 pounds of air, which produces an easy effect upon the car. 

 They are made in different types for touring cars, electric and 

 light commercial vehicles and trucks ; can be placed on any 

 clincher or straight side rim and are guaranteed for 8,000 to 

 10,000 miles. [The Punctureless Auto Tire Co., Akron, Ohio.] 



THE TWELVE-INCH TIRE. 



The 12-inch tire is scarcely likely soon to become a formidable 

 rival of the automobile tire of standard size, in public popularity, 

 but some very interesting "stunts" may be accomplished on 

 tires of this size— by those skilled in their performance. We re-

produce a photograph of Ed. Mayer in a vaudeville act in which, 

 under the name of Francis Le Maire, he has gained popularity 

 through his performance on monocycle skates, equipped with 

 12 X 1-inch tires. As will be noticed, the position of the foot in 

 skating is on top of, or directly over, the wheel, a particularly 

 difficult one to maintain. 



Mr. Le Maire — or Mayer — has also attained distinction in 

 amateur bicycle racing in the West, and in all of these events. 



as well as in his stage equipment, he uses Palmer tires, made by 

 The B. F. Goodrich Co., Akron, Ohio. 



A NEW TIRE ACCESSORY. 



device that stands for preparedness when the 



Here 



motorist encounters deep, sandy roads or faces the possibility 



of being stuck in the mud. 



It will be seen by referring to the illustration that it is an 



exceedingly simple contrivance made of metal, fitting snugly 

 around the curve of the 

 tire and held in place by a 

 leather-covered chain pass- 

 ing around the felly. It is 

 comparatively light in 

 weight yet amply strong 

 enough for the purpose for 

 which it is designed. A pair 

 of these trouble savers oc- 

 cupies only a small space in 

 the tool box. and doubtless 

 the day would come when 

 they would be used to good 

 advantage. 



When power is applied, 

 the "Dig-U-Out," as it is 

 called, prevents the wheel 

 from slipping by acting as 

 a lever, and practically lifts 



tlie car out of the deep mud or sand. It is made in 5 sizes, for 



pleasure cars and trucks, fitting both pneumatic and solid tires. 



It is confidently expected that this invention will be used on 



United States Amy trucks in Mexico. [The Protex Co., 1790
