A NEW TYPE OF RUBBER HEEL 



Rubber heels that wear down on one side in the same manner 

 as leather heels will have to look to their laurels, if the makers 

 of the newer type revolving rubber heels speak true. The Kogers 



revolving rubber "Duplex" 

 heel is made on a princi- 

 ple generally in use in 

 Europe but little known on 

 this side of the water. As 

 shown in the illustration a 

 disk of rubber is sunk be- 

 low the level of the heel. 

 This revolves in use, all 

 parts receiving the wear 

 alike, and it absolutely can- 

 not "run down." Slipping 

 is claimed to be reduced to a minimum and maximum wear is 

 attained, as the heel is discarded only when worn thin and flat 

 all over. — The Rogers Rubber Co., Inc., Century Building, Pitts- 

 burgh, Pennsylvania.

CANADIAN TIRE DESIGNS 



Two new designs of the Canadian "V. D, L 

 distinctive "Guard" and 

 "Touring" tread casings, 

 designed to meet vari- 

 ous highway conditions. 

 "V. D. L." tires are all 

 Canadian in manufac- 

 ture and are backed by 

 Canadian capital. They 

 are claimed by the maker 

 to be the result of the 

 experienice of some olf 

 the foremost tire engi- 

 neers on the North 

 American continent. 

 They are hand-made to 

 meet Canadian road con- 

 ditions and give great 

 mileage and more com- 

 fort, being supersize. —

AN AMERICAN SOLE AND HEEL PAD SET 



The Emory rul.>bcr sole pad is a patented device, made in two 

 parts, to be attached to the leather half-sole of a shoe, the prin- 



Ehory Sou and Heei. Pads 



ciple being the same as that of the rubber heel. This sole is 

 made in two pieces in order to give greater service, as a whole 

 half-sole of rubber is likely to crack at the point of bending. 



It is not heating to the feet, and it cushions the shoe, making 

 walking easy by absorbing shocks. It is non-skid, which is a 

 big asset in wet weather. Emory rubber heels are designed to 

 conform to the sole, are as near non-skid as possible, and are 

 made of springy live rubber. — The Emory Rubber Sole Pc

RED SHORT BOOTS FOR SERVICE 



Rubber boots that are built like tires for miles of hard wear 

 are the product of a rubber manufacturer whose tires are guar- 

 anteed for a long mileage. Hood "Red" boots are built for 

 service and every place where hard wear can attack a rubber 



boot has been 

 made the sub- 

 ject of special 

 study with the 

 idea of forti- 

 fying these 

 places to resist 

 the hard usage. 

 The heavy gray 

 rubber molded 

 heels and eight- 

 ply soles are 

 tough on 

 1 1 icks" and are 

 mined by the 

 Hood tire proc- 

 ess to the high- 

 grade red up- 

 pers. The soles 



run all the way under the heels and cannot come apart; they are 

 claimed to give better mileage than the soles of the average boot 

 without cracking. An extra thick vamp and heavy duck lining 

 add materially to the life of the boot, which is cured under heavy 

 pressure. Hood "Red" boots have light-colored foxing and look 

 just as well as they wear. — Hood Rubber Products Co., Inc., 

 Watertown, Massachusetts.

A DUAL TREAD CORD TIRE 



A distinct dual tread cord tire which is the result 

 of experiment and research work 

 is the "Wiregrip" tire. The mak- 

 ers assert that in this new tire is 

 embodied the duel vacuum tread. 

 Skid blocks extending across the 

 carcass of the tire diagonally per- 

 mit the carcass to flex freely in 

 any desired direction. The cross 

 section is built wide and low, dis- 

 tributing the flex of the tire from 

 bead to bead. It is said to develop 

 remarkable ease of riding and in 

 fast driving to show a marked 

 tendency to hug the road. — The

VALVE CAPS BOXED IN SETS 



Recognizing a need in the tire 

 world, a manufacturer of tire 

 valves is putting out sets of five 

 caps in small metal boxes. Valve 

 caps were found missing from 

 1309 Broadway automobile valve- 

 stems in a recent survey. — A. Schrader's Sons, Inc., 783 Atlantic
