THE INDIA RUBBER WORLD 



609 



A similar automatic switch is marketed for ignition circuits, 

 also a combined ignition and lighting switch, working on the 

 same principle. Both of these are designed to prevent the drain- 

 ing of the battery, should the driver neglect to throw the switch 

 off when the engine is stopped. 



The bases of these ingenious devices are made of molded hard 

 rubber with the terminals embedded in the same material, thus 

 insuring perfect insulation. [Hartman Electrical Manufacturing

FOED REAR WIND-SHIELD.

wind-shield which gives 

 the same protection 

 against the elements for 

 the passengers that the 

 driver enjoys. This con- 

 venient addition to the 

 comfort and pleasure of 

 motoring is made of 

 heavy rubber cloth with 

 transparent part itions.

AN niTESCHANGEABLE RUBBER HEEL. 



Few people wear the heels of their shoes uniformly — some 

 wear down the outside of the heel, others the inside, while 

 almost everyone wears of? the back of the heel rather than 

 the level tread. Rubber heels when 

 worn down lose their resiliency, of 

 course, as the thickness of the rub- 

 ber is reduced. Therefore it has 

 been found desirable that the heels 

 might be interchangeable, so that 

 when worn off on one side they 

 could be reversed from one shoe to 

 the other, and thereby give longer 

 service than would otherwise be 

 possible. 



A heel made for this purpose is 

 shown in the illustration, both the 

 upper and under surface being pre- 

 sented. When on the shoe it dif- 

 fers in no respect from any other 

 makes of rubber heels. The ap- 

 plication to the shoe, which also 

 allows for the interchangeable fea- 

 ture, is explained by the pictures. 

 A metal fastener is attached to the 

 shoe, over which the heel is then sprung through its resiliency. 

 The method of application is to lay the heel, with the fastener 

 in place, upon the prepared leather heel; then a light blow- 

 on the rubber heel will cause the "dogs" or points on the 

 fastener to mark the exact position in which the fastener is 

 to be nailed. This fastener is then removed from the rubber 

 heel and nailed securely in place. The rubber heel is then 

 sprung over the fastener, and the concaved surface springs 

 fiat and seals the joint between the shoe heel and the rubber 

 heel. Of course, it is a simple matter to remove such heels, 

 and transfer them to the opposite shoes after they have been 

 run down on one side. The heels cannot be pulled off 

 accidentally and will not crow-d or shift out of place. They 

 are made in various sizes for men's and women's shoes.

ANTEBIOR-METATARSAL ARCH SUPPORT. 



-Most arcli supports are iiUiiuled to raise the arch extending 

 from the heel to the ball of the foot, and many and varied are 

 their forms and composition. As is well known, there is another 

 arch in the human foot, that across the ball, at 

 the bases of the toes; in anatomical language, the 

 anterior or metatarsal arch. A disarrangement of 

 the bones of this arch is the cause of severe suf- 

 fering. To overcome and remedy this a special 

 arch is made. It is claimed that the construction 

 of this support is such that adjustment may readily 

 he made to fit the form or structure of the bones 

 cii the foot, by means of the pocket placed in the 

 ui)per end of the support into which the user places 

 the specially devised pad of rubber molded to 

 conform with scientific accuracy to the natural contour of the 

 anterior metatarsal arch. This arrangement enables the user to 

 adjust the pad in the exact position which affords greatest re- 

 lief. The contact of the rubber pad against the upper layer of 

 soft, flexible leather and the bottom layer of felt, holds the rub- 

 ber pad in the position in which it has been placed, and its use 

 tends to bring the bones back to their proper position. [Xathan

RUBBER IN THE NURSERY. 



The inventor of the rubber bib, besides sharing in the sure 

 profits of the present, is in line for the promised reward to tht 

 benefactors of the little ones. The rubber bib is not a new 

 article of manufacture. It is not improbable that it has been a 

 source of comfort to babies since grown up to engage in its- 



manufacture and >al(.-; Imt it dues contribute to a child's comfort, 

 offering relief from the irritating effects of the frequent spilling 

 of milk over the neck and chest. Neither is the nurse's rubber 

 apron new, its practical utility having been for some time recog- 

 nized. The styles shown in the illustration, however, are in new 

 decorative materials, the effect being quite different from the 

 bibs and aprons hitherto in vogue. [Currie, Thomson & Co., 

 London, E. C, England.] 



THE THEO ELASTIC GIRDLE. 



This is a new elastic girdle. It is made entirely of a wash- 

 able, porous, surgical woven elastic, boned front and back with 

 rust-proof steels, the front ones being of the new French soft 

 top variety. It is suitable alike for growing girls and adults, 

 and for bathing and athletic, as well as ordinary wear. Each 

 girdle has four hose supporter straps of firm, substantial elastic 

 with padded loops and all-rubber buttons. This corset is made 

 in various materials, in white and pink, and is from 7 to 16 

 inches in length. [M. W. Schloss Manufacturing Co., New York
