NEW FEATURES IN TIRES. 



GOOBRICH "WIRELESS" TIRE. 



■ I 'HE new Goodrich "Wireless" solid tire consists of three in- 

 ■* tcgral factors : A special steel base with dovetailed grooves 

 on the top surface ; a hard rubber sub-base, which is inseparably 

 united with the steel base, and a soft rubber tread or tire proper, 

 inseparably vulcanized upon the hard rubber sub-base. The lire 

 is mounted on a special steel rim, or felloe band, which projects 

 far enough on either side to protect the rubber from jamming 

 against curbs and the like in service. It is held in place on this 

 band by means of lug bolts on either side of the steel base, and 

 a key on the felloe band which fits into a keyseat on the inside 

 of the steel base of the tire, thus preventing circumferential move- 

 ment. The fastening point of the Goodrich "Wireless" tire is 

 steel to steel, and is, therefore, absolutely secure. The improved 

 constructed makes it possible to set the twin tires on the rim 

 in direct contact with each other. This reduces the space be- 

 tween the tires to the minimum necessary to prevent skidding and 

 displacement of the rubber under stress. [The B. F. Goodrich 

 Co., Akron, Ohio.] 



NEW "AJAX" NON-SKID TIRE. 



The tread of this tire is not molded, but is wrapped on the 

 shoe by the same process by which the ordinary smooth Ajax tire 

 is made. The new Ajax tread differs in appearance from the 

 average non-slipping styles ; its raised parts being quadrilaterals

3-16 inch in depth, arranged diagonally across the tread. These 

 are placed for enough apart to prevent squeezing and flattening 



into a smooth surface when imder weight and in contact with the 

 road surface, which would cause slipping on wet pavements or 

 mud, which non-skids are intended to prevent. The tire itself 

 is heavier than the smooth model, the 3j/^-inch size having five 

 plies of fabric. [.Ajax-Grieb Rubber Co., New York.] 

 SEATON SFEINO WHEEL. 



The American Spring Wheel Co. (No. 227 Williamson building, 

 Cleveland, Ohio) have been organized to manufacture the Sea- 

 ton spring wheel, and the same interests have incorporated the 

 International Spring Wheel Co., to handle the European patents

on this invention. An important interest in the new companies 

 is held by Mr. William E. Metzger, some time general sales 

 agent for the Cadillac Motor Car Co., after which he formed the 

 Everitt-Metzger-Flanders Co., automobile manufacturers. He 

 has sold his holdings in this to become connected with the Sea- 

 ton spring wheel manufacture. Mr. Metzger refers to the Seaton 

 as the first spring wheel to successfully make possible the use 

 of solid tires on all types of vehicles, both commercial and 

 pleasure.
