THE INDIA RUBBER WORLD 



[November 1, 1911. 



THE NEW INVISIBLE OVEHSHOE, DOVETAIL AIH CUSHION ETIBBER STAMPS. 



For a good many years inventors have been trying to devise Rubber stamps made by the patented dovetail air cushion

his rubbers, no matter how much he may want to wear them. 

 Because of this general desire to have rubbers, but not show 

 them all manner of clogs have been put on the market, the most 

 advertised and best known being the "Everstick," a great many 

 pairs of which have been worn during the last few years. 



Now comes a new invisible rubber shoe, or more properly a 

 rubber sole, and its quality of invisibleness cannot be questioned 

 for it simply fits around the sole, although it can be made with 

 a suggestion of a vamp at the toe. It differs from any former 

 invisible rubbers in a mechanical device at the shank of the 

 shoe which holds it on, whence its name the "Lockon." This 

 locking device as shown in the accompanying cut consists of a 

 rubber loop running back from the sole and ending in a metal 

 buckle, which catches in a staple, which is fastened in the shank 

 of the leather shoe. 



It is claimed that this rubber sole can be put on and removed 

 as readily as the ordinary overshoe. [Maurice C. Clark, Provi- 

 dence, Rhode Island, patentee.] 



"ROUGH RIDER" GRIPS FOR BICYCLES. 



Grips for bicycles and motorcycles of the "rough rider" type, 

 are among the recent offerings. They 

 are made with a basket-weave sur- 

 face, which affords a very comfortable 

 grip for the hand and avoids the

stickiness of a smooth surface. These grips are made in either 

 red or gray. [Morgan & Wright, Detroit, Michigan.] 



MACKINTOSH COVERS FOR AUTO SEATS. 



The OWNERS of fine cars who want to keep the uphol- 

 stery in good condition can get waterproof cushion covers for 

 this purpose. They should see, however, that the covers are 

 actually waterproof, and that they fit the cushions properly, 

 covers too big being almost as unsatisfactory as covers too 

 small. They should also see that they are reinforced with 

 patches under each fastener to prevent them from pulling out.

using the stamp one can see where it is going instead of guess- 

 ing at it, as in many of the square edged stamps. Moreover the 

 cushion is dovetailed into the moulding so that it cannot fall 

 off as often happens with the ordinary stamp. [Lamb & Tilden, 

 Washington, District of Columbia.] 



A CLAMP FOR HOSE 



. When hose becomes spongy or leaky it is a good idea to 

 cut out the leaky section, trim the two ends evenly and clamp 

 them together with the proper tube inside. 

 Here is an illustration of a little clamp for use 

 in garden hose. This clamp is put over the 

 hose, a nail or a piece of wire or a punch is 

 inserted in the hole at the top, and then by a 

 few backward and forward movements of the 

 nail, which catches in the holes of the inner 

 band, the clamp is gradually tightened and held 

 by the pawls of the top piece which catch in the notches of 

 the inner band. [The Walker Hose Clamp Co., Battle Creek, 

 Michigan.] 



RUBBER PADS KEPT HOT BY ELECTRICITy. 



The hot water bottle, generally useful though it is, has some 

 disadvantages. It is hottest when first applied, and gradually 

 cools and has to be removed from the patient for refilling. It also 

 has considerable weight, which in certain sensitive cases is trouble-

some. The J-M Electrotherm is designed to obviate all these dis- 

 advantages. It is light, is heated by electricity so that the heat 

 can be turned on gradually and continued as long as desired. It is 

 a soft, flexible pad, rubber surfaced, like that shown, and contains 

 carefully insulated wires. When connected with an ordinary 

 incandescent light socket the Electrotherm heats to any desired 

 temperature in a few minutes. A regulating switch makes it pos- 

 sible to turn on any degree of heat desired, and a thermostat 

 automatically limits the temperature to a safe degree. [H. W. 

 Johns-Manville Co., No. 100 William street. New York.]
