NEW GOODS AND SPECIALTIES IN RUBBER. 



"LIRE preserver" TIRE TREADS. 



ADETACHARLIC tire tread whose function is to pre- 

 serve and increase the longevity of the tire is an 

 Ohio producti n that appears to have much meri . 

 It is molded so as to conform to the shape of the 

 tire, and is made of one piece of tough rubber reinforced by a 



special weave of canvas. 

 Slipped on over the de- 

 flated tire, it is firmly 

 held in place by means 

 i)f a steel cable which 

 passes through a series 

 of brass ornicicel hooks 

 attached to the edges 

 of the protector. The 

 cable is tightened 

 with a turnbuckle and 

 cannot work loose. 

 It is claimed that this 

 detachable tread is in- 

 destructible and skid proof, and that while it is in use a tire 

 puncture is an impossibility. The protector would thus 

 seem to be a, tly called the " Life Preserver." [The Pneu- 

 matic Tire Protector Co., Dayton, Ohio.] 



RUBBER HEEL ATTACHED TO LEATHER. 



The accompanying sketches 

 relate to a newly patented rub- 

 l)er heel, the foundation of 

 which is a metal plate, which 

 is coated with unvulcanized 

 rubber and then vulcanized into 

 the body of the heel. The 

 flanged edge at the side of 

 the heel secures a firm joint 

 with the leather. The cavity 

 in the middle of the heel is 

 provided for the purpose of in- 

 creasing its resilience. The 

 cavity may be made with cress 

 ribs, as shown in the upper- 

 most drawing. The heel is 

 patented by Charles Yahrus 

 and F. A. Hammer, of Woon- 

 socket, Rhode Island.

AN "automobile' SKATE. 

 lNi)if.\TiONS point to the return of the roller skate to a 

 large measure of the popularity it enjoyed nearly a genera- 

 tion ago, when the 

 larger cities were 

 fairly peppered with 

 rinks, and every 

 small town had at 

 least one of those 

 centers of pleasure. 

 The fad was widespread and for a season held the country 

 in its grasp. Its reign was brief however, and in a re- 

 markably short time roller skating became an almost for- 



gotten pastime. In the present revival of roller skating 

 rubber plays an important part ; in fact the introduction of a 

 new type of rubber wheeled skate may be said to be respon- 

 sible for it. The newest roller skate is called an "automo- 

 bile " or pneumatic. That is because two inflated rubber 

 tired wheels, with ball bearings, take the place of the four 

 solid wood wheels, of the old type of skate. As will be seen 

 by the illustration, the body of the skate lies below the axles, 

 thus doing away with the old time top-heaviness. The rub- 

 ber tires are of two types — pneumatic and cushion. They 

 are held in place by substantial inner lugs, which are a jiart 

 of the tire itself, screws with nut fastenings passing through 

 the lugs and cl.imping the steel spokes and tires in one solid 

 wheel, which runs on steel ball bearings. The metal parts 

 are polished and nickeled. It is claimed for this skate that it 

 overcomes the tendency to -fall backward, and that both 

 wheels are always on the floor. The skate has a length of 

 from 10 to 12 inches, the varying length being obtained by 

 means of a telescoping steel tubing which forms the main 

 structure, or keel. The wheels also are variable, being from 

 4 to 5 inches in diameter. [Cycle Skate and Sporting Goods 

 Co., New York.] 



A PRACTICAL TIRE SHOE MENDER. 

 The Shaw Gaiter is a device which seems bound to find a 

 place in most automobile repair kits. There are strong reasons 

 for this. First 

 and most im- 

 portant, is the 

 fact that it 

 does what is 

 claimed for it 

 — repairs tire 

 punctures and 



blow-outs quickly and effectually. Of course the mending 

 is only temporal^-, but it answers the purpose for the time 

 being and enables the stranded motorist to get home or to 

 some shop where the damage may be repaired in a more 

 lasting manner. The gaiter is of leather, with stout, se- 

 cureh- fastened leather tread, and when adjusted completely 

 envelops the tire for a space corresponding with its own 

 length It is secured to the rim with stout leather lacings. 

 It is made in lengths varying from six to sixteen inches, 

 and in sizes to fit any tire from the motorcycle to the largest 

 automobile. [The Shaw Motor Tyre Tread Co., Birming- 

 ham, England.] 



SOMETHING NEW IN OVERSHOES. 

 SoMETHiNC, new in footwear is the .Stazon, a rubber over- 

 shoe which is made on a last that has as its distinctive 

 feature an exaggerated 

 curve. The object of 

 this peculiar shape is 

 to prevent the annoy- 

 ance which is so fre- 

 quently caused when 

 walking by the slipping 

 of the ordinary over- 

 shoe. Furthermore, the Stazon is guaranteed not to come 

 off until it is taken off. The style also commends itself to
