SLEEVE FOR WEAK TIRES. 



■yHE "IDKAL TWIN" Sleeve, illiistratod, is designed to pro- 

 ^ vide against blowouts or rim cuts in automobile casings. 



It consists of an inner sleeve, which fits the inside of the cas- 

 ing, and is set in place inside the shoe, pulling both flaps out 

 under the beads of the casing. The outer "twin" is carried up 

 over the shoe, placing the flap underneath the bead and between 

 the casing and the inner "twin," the lap of the inside "twin" be-

ing brought over the bead. The casing is then replaced on the 

 wheel, just as though no repair had been made. 



The sleeves are made from the highest grade of cotton dack, 

 from 15 to seven plies, according to size, with beveled edges to 

 insure a smooth surface for the tube. They have a flap on each 

 side that passes over the rim and holds the sleeve in place, and 

 when adjusted it is claimed that the\' take the strain entirely off 

 the shoe, making them invaluable where a weak spot develops on 

 the shoe. [Voorhees Rubber Manufacturing Co., Xew York.] 



CLAHP FOR AtTTO HOSE. 

 This clamp was designed to insure perfect circulation in the 

 cooUng system of automobiles, by fitting with equal pressure at 

 every point in the circumference of the hose. It is stamped 

 from sheet brass, and when used is wrapped around the hose 

 twice, the openings on each side of the clamp meshing with each 

 other, and kept in position by small lugs as shown in cut. A

T-bolt, hinged as shown with wing nut is dropped through the 

 slot in the opposite side, the bolt being kept from coming out 

 by the cup-like formation of this end. [Thomas. B. Rcid, Mor-

THE "JELCO" PUNCTURE-PROOF TIRE. 



A TIRE that combines, with puncture-proof qualities, all the 

 life and resiliency possessed by the best rubber tires of the past, 

 was the object aimed at by the origination of the "Jelco" punc- 

 ture-proof tire. In seeking to attain it, the ordinary rubber tire 

 was reinforced by a layer of rubber, in which steel discs are

imbedded in alternate layers, overlapping one another without 

 touching each other. The principle will be readily understood 

 from the accompanying illustration, in which the location and 

 arrangement of the discs is clearly shown, as well as the manner 

 in which they protect the air chamber from nails and other point- 

 ed bodies that may perforate the shoe, and which, in the tire of 

 ordinary construction, would have resulted in an inevitable punc- 

 ture. [J. Ellwood Lee Co., Conshohocken, Pennsylvania.] 



TIRE INFLATION MADE EASY. 



The labor of pumping up a tire, often with a pump ridicu- 

 lously inadequate for the work, is avoided by the smart auto- 

 mobilist who makes use, in place of the pump, of the Goodyear 

 -Air Bottle. A small steel tank, charged with compressed air, it 

 can be stowed under the seat or strapped to the foot-board. When

a tire needs inflating, all that is necessary is to attach the hose 

 to the tire valve, turn on the air, and in a few moments the tire 

 is blown up. A pressure gauge on the tank tells when the tire 

 is properly inflated, a very important point in obtaining full ser-
