These heels are no heavier than ordinary ones, though they are 12. 14, ISyi, W/z, IT/z inches, and extra special for 3j4, 

 are bigger and an eighth of an inch deeper, which means longer 4. 4'/. and S-inch tires are 17, 19, 20 and 21 inches.— Fowler-

THE FIRST TORONIZED TIRE 



One of the newest tires is pictured here, wliicli dci)ends on its 

 internal hydraulic expansion process in addition to ihe high 

 quality of its materials to produce an oversize tire guaranteed 

 against rim cuts, stone bruises and blow-outs. 

 The foundation of this tire is the new 

 moisture-proof fabric treated by the patented 

 toron process which is said to increase the 

 tensile strength and friction and minimize 

 tlie tendency toward oxidation and decay. An 

 additional amount of rubber is calendered in- 

 to this fabric, made possible (because of the 

 special affinity for rubber credited to toron. 

 This process also protects the tire against 

 the free sulphur which comes from ordinary 

 vulcanized rubber. The toron process was 

 described in The 1ndi.\ Rubber World, 

 October 1, 1920, page 26. 



The "Hydro-United'' tire is built over a 

 three-piece collapsible core, for which is sub- 

 sequently substituted a heavy fabric bag the 

 exact size and shape of the inside of the tire. 

 The uncured tire is placed in the mold which 

 is closed by hand without external pressure 

 and the mold placed in the vulcanizer. Water 

 heated to vulcanizing temperature is then 

 pumped into the fabric bag through a connec- 

 tion extending through the mold. A pressure of 200 pounds to 

 the square inch produces a tire of uniformly united parts, per- 

 fectly vulcanized, without any exterior strain. — Hydro-United

 sylvania.

NEW BLOW-OUT BOOT 



The Fowler "Spear-Lock" blow-out boot comes to automo- 

 bilists with a guaranty of a permanent repair that will not cut the 

 tube, creep, blow out or bulge. This boot locks the tube within 

 it.sclf, taking the 

 full strain of the 

 air pressure. The 

 ruibber apron, 

 which is an ex- 

 clusive feature, 

 takes up the fric- 

 tion, making it 

 harmless, a n d. 

 acting as a gas- 

 ket, keeps out 

 water, dirt and 

 sand. The appli- 

 cation of this 

 boot is quite 

 simple. The in- 

 jured rubber and 

 fabric is cut away, making a clean hole through the tire. The 

 boot is placed on the tube about 18 inches to the left of the valve 

 stem and inserted in the tire before inflating. The tube is then 

 inflated enough to hold the boot in place until the tire is on the 

 rim, and then inflated to full regular air pressure. The boot 

 should extend at least three inches on each side of the hole. 

 Ordinary length boots for 3-, S'A-, 4-, AYz- and 5-inch tires 

 are, respectively, 9, 11, 12^, 13J/2, WA inches. Special lengths

RUBBER-SOLED SHOES ADVOCATED FOR GOLF 



Progressive sportsmen who like to see well-kept golf links 

 have long deprecated the damage done to turf on the putting 

 greens by some types of sports shoes intended to afford the 

 player a tirmer footing. Such will welcome the recent advocacy 

 of rubber-soled golf shoes which obviate injury to the turf and 

 the club-house floor as well as improve the player's game. 

 Pliable and comfortable, at the same time that they furnish 

 adequate security against slipping, the new types of rubber-soled 

 golf shoes should find ready favor during the coming season.

Practice Golf Ball Substitute 



GOLF WITHOUT LINKS 



All the excilement of an ri,L;btiLn-liole course without the at- 

 tendant embarrassment of a "gallery" is promised the golfer who 

 uses a newly patented substitute for a practice ball in the house 

 or the back yard. This clever 

 invention utilizes the elastic 

 ])rinciple of rubber to provide 

 a substitute for a golf ball, 

 which after being hit imme- 

 diately returns to its original 

 position in readiness for another stroke, and requires no teeing-up. 

 The construction provides for a rubber mat through which is cut 

 a recess hole, out of which protrudes a rubber tongue of somewhat 

 globular forin and of the same dimensions as the average sized golf 

 ball. This rubber tongue is firmly held by a countersunk screw 

 at the same height above the mat as a golf ball when teed-up. 

 When hit by the club the rubber tongue flattens out against the 

 mat and, as soon as the club passes over it, springs back to its 

 original position. Its use is said to perfect a golfer's stroke and 

 to provide a maximum of practice with a minimum amount of lost 

 motion. — Edward J. Vogel, Sail l->aiu-isco, California ; United 

 States patent No. l,363,44fi.

RUBBER-TIRED WHEELS FOR THE "KIDDIE-KAR" 



The story of the man who made stereoscopes — and still makes 

 them — but left his work one day to make his small boy a strong 

 wheeled toy that would not easily wear out, is only one of the 

 interesting "real life" bits that furnish the color and romance in 

 modern business success. When the small boy ventured forth 

 with his new vehicle, all the other small iboys wanted 

 one like it, and father was forced into a new line of 

 Inisiness. 



The almost instant success of the "Kiddie-Kar" 

 with its solid-looking wooden wheels was only the 

 forerunner of the greater 

 success that would come 

 to it when eqiiipped with 

 "real rubber tires." The 

 "Kiddie-Kar Special," as 

 the new model is called, 

 has double disk electric- 

 ally welded steel wheels 



with dust-proof roller r,i>, __,_■ mi^.a,*^, - 



bearings, and these K I D D I E -^M^Fl 



wheels are fitted with ^''=" '■^^''ec.al"— Rubber-Tired 



large rubber tires in sizes from J/2-inch on the No. 1 model to 

 %-inch on the No. ,^. The finish of the wheels is baked red 

 enamel and of the "Kar," red and cream. These toys are packed 

 one dozen in a crate, with the exception of No. S, which is packed 

 by the half-dozen.— H. C. White Co., North Bennington, 'Ver- 

 mont ; 200 Fifth avenue, New York.
