UriLITY 



FOE A nOZEN DIFFERENT PURPOSES. 



Mullum in parvo is the motto of the true camper. He wants 

 every article of his outfit to serve as many purposes as possible 

 — the more the better. Now here is an article called the Sports- 

 man's "Utility" Cushion that will appeal to every sportsman. It 

 is a rubber cushion, shaped like the accompanying illustration, 



made to fit around the neck. When 

 it is deflated it can be carried in 

 the pocket. When it is full of air 

 it surrounds the neck and covers 

 both shoulders with a thick pneu- 

 matic cushion, on which guns, pad- 

 dles or canoes can be carried for an 

 indefinite length of time without 

 leaving a sore spot ne.xt day. More- 

 over, when you get back to camp 

 it serves as a cushion by day and 

 The fisherman or the duck hunter will find 

 it vastly preferable to sitting on damp logs or wet ground. 

 Then again it makes a perfect swimming collar, and in case of 

 need an effective life preserver. It is covered with brown duck 

 to increase its service. [Iver Johnson Sporting Goods Co., Bos- 

 ton, Massachusetts.] 



TO STRIP INSULATION FROM WIRE. 



The ordinary way of removing insulation from wire is to take 

 a jack-knife and do it laboriously and with considerable danger 

 to the fingers — not to mention more or 

 less damage to the wire. A little tool 

 has been invented that will obviate all 

 this, making it possible to remove in- 

 sulation from single or duplex wires, 

 easily and rapidly.' It is a small tool- 

 only SYz inches long and V/i inches 

 wide, so that it easily can be carried in 

 the pocket It is shown in the accompanying cut. It consists 

 of a steel spring handle, with cutting edges, constructed espe- 

 cially for this work. On referring to the illustration it will be

noticed that there are three twin sets of cutters. The double 

 cutters at the right are for the purpose of separating duplex 

 wire ; the smaller double set in the center is for use in splitting 

 insulation on a single wire; the parallel scraping jaws at the 

 left are for the purpose of removing the insulation and scraping 

 the wire clean and ready for soldering. [Mathias Klein & Sons.

A RUBBER SLEEP PRODUCER. 



A recent issue of one of the New York dailies, in its Sunday 

 magazine section, contained an illustrated article on a new sleep- 

 producing machine, consisting of a small tank of water, some 

 distance above the sleeper's — or rather^ the non-sleeper's — head, 

 from which runs a rubber tube, carrying water through a small 

 rubber bag or pad fastened over the patient's, forehead; the 

 theory being that the rhythmic sensation of the water flowing 

 slowly through the thin rubber bag on the forehead produces a 

 soothing effect and soon invites sleep. The name of the inventor 

 of this apparatus, or of the factory where it is made, is not dis- 

 closed, and inquiry fails to bring the desired information ; but 

 as the apparatus is quite simple, requiring not much more than 

 an ordinary wooden pail and a small rubber tube, any insomniac 

 who is interested can construct his own equipment and try the 

 experiment.

RUBBER tips FOR SHOE SOLES. 



the United States, rubber heels have become quite popular; 

 are also quite a good many rubber soles worn, but we have 

 et begun to use fractional parts of heels or soles. In the 



Old World they carry economy 

 rather farther than we do 

 here, and make use of small 

 rubber tips to cover places in 

 the shoe that are badly worn. 

 The accompanying cut shows 

 two rubber tips which are in- 

 tended to be cut apart and 

 used on the sides of the soles.

•'LONGALYFE' FOR RUBBER. 



The most interesting toy for 

 the boy of these days is the 

 model aeroplane which, with 

 a. motive power of rubber bands, can be made to sail through the 

 air for a thousand feet or more. But the life of a rubber band 

 under tension is not so very long. An English firm has re- 

 cently brought out, under the name of "Longalyfe," a prepa- 

 ration which it claims lengthens the life of rubber by preserving 

 its natural elasticity. It is especially recommended for use on 

 model aeroplane rubber, "as it permits a greater number of turns 

 to be made, and at the same time giving more power in the 

 winding, owing to the elasticity of the rubber being increased." 

 This preparation has been subjected to many tests and experi- 

 ments, and its use, it has been proved, will materially lengthen 

 the life of rubber goods. [Allen, Knight & Co., London, E. C.,

TIRES AND CHAINS ALL ONE. 



The chain has come into considerable vogue among motorists, 

 because it helps the tire, to grip the roadway, particularly when 



because of ice and snow the 

 roadway is likely to be slip- 

 pery; but the metal chain has 

 two distinct disadvantages :, it 

 is very hard on the road-^-a 

 feature which, of course, does 

 not keenly interest the motor- 

 ist — and it is very hard on the 

 tire — a feature that does keenly 

 interest him. The United 

 States Tire Co. has just 

 brought out a new develop- 

 ment of chain construction 

 that obviates both of its dis- 

 advantages, because it makes 

 the chain a constituent part of 

 the tire. Instead of being 

 metal it is rubber. In other 

 words, there is a raised pattern 

 of a double chain running 

 around the ridge of the shoe, 

 as shown in the iJIustratiqn. 

 This rubber chain grips tiie 

 road. and. of course, obviates 

 to a considerable extent the 

 tendency to skid. At tlie same 

 time it not only does not in- 

 jure the tire but considerably 

 increases its wearing capacity.
