THE INDIA RUBBER WORLD 



151 



A point that the Firestone Tire and Rubber Co. (.Akron, Ohio) 

 make about their '"Dual" tires is that, in case accidents happen to 

 them, it very rarely happens that both tires are affected, and, 

 therefore, results are never likely to be serious. 



The Goodyear Tire and Rubber Co. (Akron, Ohio) are push- 

 ing their "Wing" tires in the carriage trade very successfully. 

 It will be remembered that the "Wing" keeps water, sand, and 

 grit from working between the channel and the tire, and all 

 the wear, therefore, comes upon the tread. 



The Swinehart Clincher Tire and Rubber Co. (Akron, Ohio) 

 are out with a new motor truck tire of the twin form, molded 

 in one piece, held by clincher fastenings, and by a quarter inch 

 steel cable encircling the portion between the two sections. 



The Michclin Products Selling Co., Inc. (New York), have 

 been furnishing with marked success an extra heavy non.skid 

 tire with Samson covering for fall and winter use. 



The B. F. Goodrich Co. (Akron, Ohio) are now regularly 

 equipping with their 1907 tires cars manufactured by the White 

 Sewing Machine Co., the E. R. Thomas Motor Co., the Winton 

 Motor Carriage Co., the E. R. Thomas Detroit Co., the George 

 N. Pierce Co., the Cleveland Motor Co., the Dayton Motor Car 

 Co., the Primier Motor Manufacturing Co., the Stanley Motor 

 Car Co., and the Moon Motor Car Co., and arc not only running 

 their tire department night and day, but are rapidly pushing to 

 completion a huge building for the manufacture of auto tires. 



Many people with the best intentions are dating their letters 

 January or February, 1906, when they mean 1907. No doubt the 

 same people are writing Morgan & Wright, Chicago, when they 

 should say Detroit. 



In bicycle tires the Diamond Rubber Co. (.\kron, Ohio) ar« 

 still pushing the "Diamond Hunter," but with a special raised 

 tread for this year's trade. 



The Harburg Tire Co. (New York) are having great succesi 

 with their new detachable rim, which can be taken off the wheel 

 in less than one minute by the use of a very simple tool. 



A new steam vulcanizcr for tires and tubes has just been 

 brought out by the John Wishhart Macliine Works, Chicago. 

 The vulcanizer is capable of repairing the smallest puncture or 

 re-vulcanizing an entire tube. 



An exceedingly effective and simple tool for removing clincher 

 tires and suitable for all sizes, has been brought out by the 

 Shawver Co.. of Springfield, Ohio. 



EUROPEAN TIRE NOTES. 



■ I "HE Continental Tire and Rubber Co. of Great Britain, the 

 * English branch of the Continental Caoutchouc and Gutta- 

 percha Co. (Hannover, Germany), are guaranteeing their solid 

 tires for 10,000 miles. 



The Gaulois Tire Co. — "Gaulois" being French — have adopted 

 and are pushing "Agrippa" nonskids on their tires. 



Andre IMichelin of Clermont-Ferrand, France, has just been 

 testing the use of antiskids on one rear wheel and on both, and 

 has proved beyond cavil that two antiskids are necessary. 



The Hannover Gummi-Kaam Co. (Hannover-Limner, Ger- 

 many) are building one type of their solids known as "Excelsior" 

 with a tread so much like the Bailey "Won't-Slip" that it looks 

 as if they were paying the inventor of that excellent device a 

 very high compliment. 



The Sirdar Rubber Co., Limited (London), advertise that their 

 tires are "free from notches, which weaken the rubber." At the 

 same time the notched tires are still in the ring. 



The twin tires on the motor 'buses in London still seem to 

 skid. An ingenious device to overcome this has been brought out 

 by Reid & Rickie, Scotch mechanical engineers, which consists 

 of an extra pair of wheels rigidly fixed to the solid rear axle. 

 When the steering wheels turn either way these wheels lock in 

 such a manner as to prevent skidding — at least so it is said. 



The English Dunlop company have .1 :__. _;udded nonskid 

 racing tire that, after severe tests, has now been put on the 

 market. Americans will remember that metal studded tires are 

 very apt to go to pieces in a race when the cars are rounding 

 curves at high speed. The steel studs that are in the Dunlop tire 

 are not only imbedded in the tire itself but are securely held by 

 countersunk washers placed behind a specially toughened fabric. 



Tire United Omnibus Co. (Brighton, England) are prepared to 

 swear that tire No. 396 on the rear hind wheel of bus No. 477 

 shows a mileage of 16,890.55 miles. It was a Peter Union solid 

 tire. 



The Automobile Club of London are about to inaugurate ex- 

 tensive trials of nonskidding devices for motor 'buses. The 

 information thus derived will undoubtedly be of the greatest 

 value. 



A new tire for heavy work is the "Hartridge," which is made 

 of five or more tires grouped together, with flat treads, held 

 firmly by side flanges and showing an obstacle to side slip which 

 is really very remarkable. 



An English tire house, and handler of Goodrich solid tires 

 are quoting in their advertisements a letter from one of their 

 customers who returned a set of tires to be "rcfixcd" after 

 having been run 80,000 miles. They are seven years old. 



"Elastes," a new tire filler, is said to be made of gelatine, 

 glycerine, and chromic acid, but mixed very differently from the 

 manner in which that well known compound had been put 

 together in the past. 



David Moseley & Sons, Limited (Manchester) offer as their 

 leader in the 1907 trade, Moseley's "Perfect Detachable" tire. 

 Instead of being beaded, the edges of the tire cover are made 

 inextensiblc by having embedded in them several strands of 

 flexible but very strong piano wire. "Yet," says their announce- 

 ment, "pending the disappearance of the beaded edge ti^s. we 

 shall continue to supply it." 



SOME WANTS OF THE TRADE. 



[374] D EQUEST has been made for the addresses of parties 

 '^^ supplying "Petrolatum," a compounding ingredient 

 described recently in this journal. 



[375] The name of the manufacturer of "Electric" rubber hose, 

 in SCO- foot lengths ; also the names of those manufacturing gutta- 

 percha tissue. 



[376] A European manufacturer wishes the address of an 

 American concern furnishing either steel or hard rubber type 

 shuttles for typewriters, similar to those on Hammond machines. 



[377] Information is asked regarding firms manufacturing steel 

 lugs that are inserted into single tube cycle tires. One part of the 

 lug is vulcanized in the tire and the other part is a screw that 

 screws into the lug. 



[378] Addresses arc wanted of manufacturers who furnish 

 cloths, surfaced, calendered and frictioned ; also the names of

[381] A correspondent writes for information concerning a 

 machine made in Germany for cutting beer bottle washers, which 

 will cut three tubes at a time, the tubes being fed in 50 or 100 

 foot lengths, so that the operation of the machine is practically 

 continuous. 



[382] A request is made for names of manufacturers produc- 

 ing carpet sweeper wheel and protector bands. 



[383] We have had an inquiry as to who manufactures the 

 Carnation brand of rubber bands. Can any of our readers give
