TIRE-MAKING BY MACHINERY. 



AGRE.\T many different machines have been designed to 

 manufacture automobile tires or to assist in their manufac- 

 ture. Perhaps the most ambitious attempt is that of the Good- 

 year Tire and Rubber Co. (.\kron, Ohio), who have installed a 

 battery of machines in their making up department. Each machine 

 is mounted on heavy castings, and is designed for two workmen. 

 It is circular in form, the tire core being held by two chucks in 

 front of the worker. Above are racks with revolving holders 

 for the frictioned duck, two for each tire builder. 



The fabric cut, as usual, on the bias, is rolled on the holder 

 with a sheet of muslin intervening to prevent sticking. It is 

 arranged so that in the different plies the direction of the threads 

 alternate, giving strength. In use the frictioned stock is led down 

 upon the core which has been covered with cement, the muslin 

 automatically being taken up by another roll. The fabric run- 

 ning under an idler to give it tension is rolled slowly about the 

 core, the speed being about 6 revolutions a minute. 



When one revolution is finished the fabric is cut, then a high 

 speed clutch is thrown in and the core revolved about 270 revolu- 

 tions a minute. Two spinning rolls, spring pressed, disc shaped, 

 and rounded on the edges, are then brought to bear on the 



tread and gradually work down on the sides until the fabric is 

 rolled tightly against the form. Triinming is done by cutter 

 rolls. The inachine is adjustable for different sized tires, and 

 both straight or clincher tires can be made upon it. One man 

 by using this machine can finish ten times more tires, in a day 

 than he could by hand work.

VAND£KBILT CUP RACE. 



THE si.xth Vanderbilt Cup race — the most important auto- 

 mobiling event in America — occurred on the Long Island 

 course near New York, on October i, in the presence 

 of more people than had witnessed this contest in any pre- 

 ceding year. More cars were entered, faster time was made, 

 and there was better racing, in the opinion of experts, than 

 in the preceding contests for this cup. The winner was 

 Harry F. Grant, with R. Vernon, mechanician, in a 6-60 

 "Alco" car. The distance, 278.08 miles, was covered in 255 

 minutes 58 seconds, or an average of 65.18 miles an hour. 

 Of the 29 entrants, 10 covered the course and four were run- 

 ning at the finish. Grant was the winner also in last year's 

 race, when he drove an "Alco" car. He was born in Boston 

 33 years ago. For the fifth year in succession the winning 

 car was equipped with Michelin tires. The grand prize con- 

 test for the $S,ooo gold challenge cup of the Automobile Club of 

 America, scheduled for the Vanderbit Cup course for Octo- 

 ber 15, was postponed, doubtless on account of the unfortu- 

 nate and unusual number of accidents, which occurred on the 

 day of the cup race. Arrangements have been made for this 

 contest in another State. 



Six years ago, when the first Vanderbilt Cup race was run, 

 every entrant was a special racing car, designed and con- 

 structed specifically for racing purposes, and the cost of 

 these special automobiles ranged all the way from $20,000 

 to $63,000 apiece. When the race was declared finished, there 

 were but four of these special cars in the running, and of 

 the four cars but one of American design and construction, 

 and that was in a state of bad repair at the end of the race. 



This year the cars run were not only of a stock type, but 

 of American construction. The point is that the automobile 

 has become standardized and that the makers profiting from 

 several years' experience are putting into machines for the 

 everyday purchaser the best that the world can produce in 

 the present state of the industry. 



The Automobile (New York) asserts. "Let there be no 

 mistake; the sixth annual Vanderbilt race is the finishing 

 touch to what has been a long drawn-out struggle between 

 the classes of cars that are made on a stock basis and the 

 character of automobile that is specially made." 



In former years wdien Michelin tires won the honors in 

 the Vanderbilt Cup races they were registered as of French 

 make, but as the Michelins have an American factory now it 

 is presumed that they did not import tires for this special 

 occasion. 



TIRE TRADE NOTES. 



The Pacific coast representatives of Ajax-Grieb Rubber Co., 

 Messrs. Hughson & Merton. of Seattle, Washington, have moved 

 into a new store, at Pike street and Tenth avenue, in the center 

 of the automobile district of that thriving city. 



Under the title The Clincher, The B. F. Goodrich Co. (Akron, 

 Ohio) issue monthly a little magazine which is one of the most 

 interesting trade publications devoted to tires. 



The Buffalo Specialty Co. (Buffalo, New York), after having 

 obtained a verdict against Goiigar & Todd, of Denver, Colorado, 

 in a suit alleging infringement of the patent granted to Charles 

 E. Duryea for the tire puncture compound "Nevcrleak," have 

 defeated a motion made by the Denver firm for a new trial.
