THE "BROWNFOOT" RUBBER BOOT. 



lA.MisoME RUBBER Ruvf comes to US from Canada. It has a 

 brown foot, with sole and heel of the same color, and 

 a white top trimmed with brown top bead. The trade mark 

 side, near the lop. is also brown. The boot is made of high- 

 grade white and brown rubber and 

 is lined with duck. It comes in three 

 heights, styled, variously, hip, "Storm 

 King" (thigh), and short, for men. 

 The sole is knurled and the brown 

 foot has a fancy tab eflfect at back 

 and front, reaching some distance 

 upward on the white leg part. 



.A very similar boot called the 

 "Grayling" is made by the same man- 

 ufacturer. It is chiefly of gray rub- 

 ber and instead of having the foot of 

 contrasting color, has the white fox- 

 ing at the edge above the sole. It is 

 made of extra quality rubber and is 

 friction lined. This boot' comes in 

 lit -Hr.wnfoot." the same heights for men as the 



"Brownfoot," and also in short 

 for boys, (Gutta Percha & Rubber, Limited, 47 Yonge

NEW SINGLE SOLID TIRE. 



The newest single solid tire attempts to overcome the 

 cause of internal friction and dissi- 

 pate the frictional heat generated 

 by traction by means of deep de- 

 pressions with cross-bars of rub- 

 ber between, at regular intervals 

 around the circumference of the 

 tire. The depressions go deep 

 enough to reach below the ponit 

 where a tire is ordinarily worn to 

 the limit of its serviceability, the 

 tire thereby retaining its distinc- 

 tive qualities without requiring ad- 

 ditional attention such as regroov- 

 ing, etc. .\t the same time the 

 shape of the depressions is such 

 that stones and other foreign bod- 

 ies cannot permanently lodge with- 

 in them. (United States Tire Co., New York City.) 



AN INNER TUBE FOR CORD TIRES. 



In order to use inside a cord lire the ordinary inner tube which 

 was designed to fit a 

 fabric tire, it must be 

 inflated far beyond what 

 was intended to be its 

 normal point of stretch- 

 ing. This tends to 

 weaken the wall, both 

 because of overstretching 

 ind of increased friction. 

 The accompanying dia- 

 g r a m in cross-section 

 The ■•Horse-Shoe Ke Cord" illustrates the additional 



NNER uBE. amount of space to be 



by the inner tube in a cord tire, as compared with that 

 n a fabric tire. The black arrow indicates the cross-section 



ot a live-inch fal)ric tire and the white arrow the cross-section 

 of a cord tire. 



The "Horse-Shoe Re-Cord" inner tube has been designed pur- 

 posely to meet these conditions. Its wall is thicker than that of 

 the ordinary inner tube, because it is composed of nine plies of 

 high-grade laminated rubber instead of the more usual six. Its 

 name is intended to emphasize its greater ability to meet the re- 

 quired conditions. This inner tube is brown. (Racine Auto Tire 



Co.. Racine, Wisconsin.) 



TENNIS RACKET COVER. 

 A rubber sheath to cover tennis rackets is 

 something that should appeal to all those who 

 take pride in keeping their sporting equipment 

 in prime condition. This sheath is in two 

 parts, each having an appearance similar to 

 tliat of a bathing cap, except that the portion 

 that fits over the lower part of the racket has 

 an opening to permit the passage of the handle. 

 The handle is gripped firmly by the rubber, 

 the upper portion of which overlaps the lower, 

 providing an entirely waterproof covering. 

 The regular tennis case may be used over the 

 rubber one if additional protection is desired 

 or should be requisite.

a neat bo.x is 



intended for 

 use in mending footballs, baseballs, 

 bladders for game balls, and other 

 rubber articles. It has been ofli- 

 cially approved by the Board of 

 Education of the City of New 

 York and is particularly recom- 

 mended by the manufacturer for 

 practical use in gymnasiums, col- 

 leges, schools and camps. The 

 box is convenient in size, namely, 

 7 by 9 by 3 inches, and contains 

 the necessary tools and materials, 

 including a special patented device for the emergency repair of 

 necks of bladders. The tennis racket sheath and repair kit are 

 put out by the same house. (Alex Taylor & Co., Inc., 26 East

ENGLISH SOI.X-PADS. 



From England 

 come the "Double 

 -Arch" sole and heel 

 pads in sizes to fit 

 all boots. They are 

 interchangeable and 

 may be arranged in 

 six different ways. 

 The rubber pads are 

 attached by leather 

 disks which, it is 

 claimed, insure a per- "Double Arch" Pads.
