MOTORCYCLE GRIPS REINFORCED WITH STEEL. 



THE Cuntincntal Rubber Works are offering manufacturers 

 of motorcycles a new grip which they call "The Woven 

 Steel Reinforced Grip." The two cuts here shown 

 will give a good idea of what these grips are. It will be

seen that these grips have a woven steel reinforcement in 

 the center or relief part of grip, which strengthens the grip 

 at its weakest point. This woven steel reinforcement is 

 pliable and does not take away from the grip any of its resil- 

 iency. The company has a number of patents now pending,

covering this construction and also covering reinforcements 

 of other materials to be used in the grip. It proposes to 

 make these grips for the manufacturers, but it does not pro- 

 pose to issue any licenses for others to make them. The Con-

ALL RUBBER AIR 7ALVES. 



A certain inventive genius in Hot Springs, .'Arkansas, has 

 devised an all-rubber valve for rubber air receptacles, like tires 

 for the auto, bicycle and motorcycle, and also for air- 

 cushions and footballs. This valve does away with all metal 

 parts, and one claim for its superiority is that it cannot 

 be iniured by the creeping of the tire. Here are four illustra- 

 tions wliich may possibly make the working of the valve a 

 little plainer. No. 3 shows the valve by itself; No. 4, a cross- 

 section of it; No. 1, a cross-section of the valve fitted into 

 a tire; and No. 2, a side view of the valve when fitted and 

 firmly attached to the tire. The theory is this: that the lower

end of the valve which projects into the tire, or other air- 

 chamber, is of such soft collapsible rubber that when the tire 

 or other chamber is filled with air the pressure causes the 

 valve to come together, entirely closing the air passage. A 

 rubber cap is fastened on the outer end of the tube, as shown 

 in Fig. 2, serving still further to make the tube air tight. 

 Theoretically, this is an interesting valve: as to just how far 

 if has been tested in practice, information is lacking. The 

 inventor and patentee is Mr. P. P. Wood, Hot Springs, 

 Arkansas. 



THE ENGLISH RESILIENT WHEEL AND TIRE. 



E.xcellent reports come across the water regarding the Lyntort 

 Resilient Wheel and Tire, which seems to be a happy combination 

 where the wheel and tire work together, each increasing the 

 resiliency of the other, and the two together giving practically 

 a pneumatic effect to a solid tire. The tire (as will be seen by 

 the accompanying illustrations) is a solid tire in blocks. This 

 sectional character of course greatly increases the economy of 

 the tire, as it is not necessary to discard an entire tire when 

 one part of it becomes injured or worn. 



It is the peculiar construction of the wheel, however, that 

 gives the Lynton combination its distinctive character. This 

 wheel is formed of two steel discs. One disc is rigidly attached 

 to the hub, while the other disc, by means of a form of ball- 

 joint, which allows it to rock in any direction upon the hub, 

 has a pronounced element of "give" to it ; which greatly in-

creases the resiliency of the tire. These two discs arc so 

 correlated that the tire— which is fitted into a seat formed by 

 the curving and spreading of the two discs at their outer circum- 

 ference—flattens out when any obstruction is encountered and 

 causes the two sides of the rim to spread. This spreading is 

 possible through the arrangement of the loose disc. But while 

 the rim at the point of contact is spreading, the part of the rim 

 diametrically opposite, that is, at the top, correspondingly con- 

 tracts; so that not only is that part of the tire which touches 

 the ground operating to overcome the obstruction, but the 

 corresponding section of the tire farthest removed is also operat- 

 ing for the same purpose— the lower section flattening out, while 

 the upper section is being compressed. 



This interplay of tire and wheel gives the "Lynton" a peculiar 

 resiliency. These wheels are made with a single tire for pleasure 

 cars, and also with double tires for commercial vehicles. The 

 accompanying cuts show both the single and the double wheels.

DEEP CUT RIVETS TO GRIP THE ROAD. 



The Leather Tire Goods Co., of Niagara Falls. New York, is 

 out with a new chrome leather tire cover differing from its 

 earlier products in having at intervals of 2 inches very deep cup 

 rivets, intended to take a strong grip of icy and snowy roads. It 

 is the hope of the manufacturers that this cover will do the 

 work which is now generally accomplished by the inconvenient 

 chain— which is not only inconvenient but hard on tire and road- 

 bed alike.
