THE INDIA RUBBER WORLD 



[ M \rch 1, 1915. 



The first motor truck tire shipment made by the United 

 States Rubber Co.*s plant at Providence to its Pacific Coast 

 agencies since the change in manufacturing policy, was shipped 

 by way of the Panama Canal. 



A factory is soon to he established at Seattle, Washington, 

 for the manufacture of spring wheels for automobiles, by W, 

 B. Rosenberg, of Corbin, and \\ A. Black, of Livingston. 

 Montana. 



A NEW DETECTOR. 



The drawing herewith shows a new device that is of interest 

 to the wireless man. It is used in connection with the 

 receiving apparatus and enables the operator to detect the wire- 

 less signals that are diffi- 

 cult to get. 



In this sectional draw ing, 

 .-( is a dielectric material 

 made of hard rubber 

 mounted in such a way 

 that it can be rotated in 

 order to adjust it. BB 

 are conductors which pass 

 the current. C is a con- 

 ducting material. D is an 

 insulating washer and E 

 is the finely divided alloy 

 which makes the contact 

 with t'ne sensitive crystal

 tector Showing the Various 

 Parts. 



THE CRAWLEY-BOEVEY TIRE CHAIN. 



A non-skid attachment for solid tires is shown in the ac- 

 companying cut. To the chain that surrounds the tire, metal 

 rings are attached at intervals. The su- 

 periority of this non-skid over the old 

 crossbar type of attachment consists in 

 the tact that the metal grips in suction 

 cup form tend to prevent skidding in 

 any direction. Another advantage is 

 that it is less destructive to the tire, 

 because, as compared with the flat bar, 

 the ring attachment spreads the un- 

 avoidable strain over a greater surface.

THE AIRLESS RESILIENT WHEEL. 



The airless resilient wheel 

 i- a spring wheel in two 

 parts, namely, tin- center 

 and a floating rim. The 

 rim consists of a solid rub- 

 ber tire and two circular 

 discs or grooved plates. 

 The center part is an artil- 

 lery wheel of wood or metal 

 with six helical springs at- 

 tached to the peripher; 

 pivoted connections operat- 

 ed by twin rollers, secured 

 to the guard plates of the 

 floating rim. By this arrangement any movement of the rim 

 compresses the spring simultaneously and equally transmits the 

 driving tone. [Airless Resilient Wheels, Limited. London, Eng-

 Europe to manufacture under the Goodyear patents. Mr. Hutch-
