THE RUBBER TIRE INTEREST. 



A 



" WEMAKA PERFECT VEHICLE TIRE. 

 DISTINCTIVE feature of this tire is its construction 

 with cross stays vulcanzed in the rubber itself, the tire 

 being held in place by separate retaining wires, being 

 independent of the cross stays, which permits the lon- 

 gitudinal com- 

 pression of the 

 rubber along 

 the retaining 

 wires. Where 

 the rubber is 

 compressed in 

 the channel, 

 the pressure of 

 the retaining 

 wires is distrib- 

 uted and equalized by the cross stays throughout the entire 

 length and width of the tire. It is thus impossible for the 

 tire to roll out of the channel, or for the longitudinal wires 

 to cut through the rubber. " Wemaka " tires )4', %, and i inch 

 wide are made with one longitudinal wire; wider tires with 

 two. [New Jersey Car Spring and Rubber Co., Jersey City.] 



THE STEVENS INDURATED FABRIC TIRE. 

 Something new in the way of tire construction appears in 

 the " Indurated Fabric '' tire, manufactured under the Stevens 

 patents. This tire is built up of many plies of specially woven 

 canvas, impregnated with rubber, and vulcanized together under 

 hydraulic pressure, The fibers are disposed diagonally to the 

 radius at any point, and only the edges of the canvas are pre- 

 sented to the road surface. The results claimed for this 

 method of construction are exceptional qualities in the way of 

 lightness, durability, and resistance to slipping. Elasticity or 

 resiliency is not 

 claimed for this 

 tire, which is in- 

 tended mainly 

 for use on com- 

 mercial wagons ^^ 

 as a substitute \ 

 for solid rubber 

 or steel tires. It 

 is secured to the 

 wheels of light 

 vehicles by the 

 means of a spe- 

 cial type of steel 

 channel, the sides of which are at right angles to the base. For 

 heavy trucks and automobiles the tires are made endless, and 

 secured to wheels by means of side flanges, as shown in the 

 illustration. In either ca^e, bolts pass through the channel 

 sides and the tire, thus aiding to hold the tire in place. In 

 the vehicles manufactured by the same company, the whole 

 machinery equipment is spring supported, the makers claiming 

 that this construction, relieving the tires of the duly of absorb- 

 ing shocks, is the logical one. [Auto- Dynamic Co., No. 140 

 West Thirty-ninth street, New York.] 



AMERICAN MADE TIRES IN BURMA. 



An advertisement prominently displayed in the daily Gazette 

 of Rangoon, Burma, though printed in the British empire, in- 



cludes not only the Hartford single tube tire, but also Dunlop, 

 "Scottish" clincher, and Palmer tires, all with "American 

 made outer covers." The latter covers are quoted at 18 rupees 

 (=24 shillings = $5.78) each. The presence of these Dunlop 

 goods on the Indian market recalls the suit recently brought 

 by the English Dunlop tire company against the related com- 

 pany in America for exporting such goods, alleged to be in 

 violation of an agreement for the division of territory. The 

 Hartford tires are listed at a trifle less each. 



THE "HARTFORD" TIRE VULCANIZER. 



This is a new vulcanizer, for use in repairing pneumatic 

 tires. The repair is vulcanized in a sectional mold while 

 inflated, thus preserving the original shape of the tire, or 

 the tire may be clamped 

 on the top of the mold, 

 thus allowing the ma- 

 chine to be used as a 

 flat plate vulcanizer as 

 well as a sectional one. 

 The heat is obtained 

 from a gas flame placed 

 underneath in the heavy 

 metal base, and, by the 

 arrangement of the 

 mold, the heated air is 

 carried completely 

 around the tire, escap- 

 ing at the top. A repair 

 may thus be made with 

 equal facility on either 

 the tread or the rim 

 portion of the tire. This 

 vulcanizer is also supplied for use with kerosene as fuel. A 

 thermometer accompanies each vulcanizer, so that the degree 

 of heat may be ascertained readily. [The Hartford Rubber 

 Works Co., Hartford, Connecticut.] 



TIRE NOTES. 



American tires were very much in evidence at a recent ex- 

 hibition of motor cars in Agricultural Hall, Islington, London. 

 The " Ideal " solid carriage tire shown by J. W. & T. Connolly 

 is that known in America as the Kelly-Springfield tire, the ex- 

 hibitors being licensees for it in Great Britain. The " Star 

 brand " solid wired on tire shown by Whittingham & Wilkin, 

 is the same as that marketed by the Batavia Rubber Tire Co., 

 of Batavia, New York. Another solid type shown was the 

 "Easy" tire, which is of American origin. The New York 

 Tyre Co., who showed a single tube tire, have the London 

 agency of the New York Belting and Packing Co., Limited, for 

 the latter"s " New York vehicle tire." 



= The Kelly Springfield Rubber Tire Co. (Davenport, Iowa), 

 incorporated August 31, 1S99, in spite of their name, announce 

 that they have no connection with any other company. They 

 are marketing solid wired-on carriage tires. 



=:Sectional Pneumatic Tire Co. (Binghamton, New York), 

 incorporated lately to manufacture a new tire, have made some 

 changes in their organization. The officers now are: E. C. In- 

 derlied, president ; B. A. Baumann, vice president; F.J. Bau- 

 mann, treasurer ; R. D. Bundy, secretary ; W. L. Bundy, gen- 

 eral manager ; Charles Miller [patentee of the tire], superin- 

 tendent.
