A LEATHER SHOE TO SAVE THE HRE. 



On the human foot it is the custom to have a rubber over- 

 shoe to save the leather shoe by keeping it dry, but in the 

 Woodworth tread for automobile tires the case is reversed, for 

 here we have a leather shoe that goes over the rubber shoe of 

 the tire to protect and preserve it. This Woodworth tread 



consists of several 

 layers of especially 

 prepared leather, some 

 inelastic fabric being 

 interlaid between the 

 pieces of leather, and 

 all fastened together 

 by a large number of 

 steel rivets, the out- 

 side heads of which 

 serve as studs, to in- 

 crease the wear and 

 to prevent skidding. 

 This leather shoe is 

 held on the rubber 

 tire by springs running along both edges, which are hooked to- 

 gether after the tread is put on the tire and thus serve to keep 

 it in place. There is no rubber in this Woodworth tread, but 

 its mission as a rubber preserver seems to entitle it to this men- 

 tion. The accompanying cut will give an idea of its construction.

THE DIAPHRAGM PNEUMATIC. 



The Angelas Piano-Player, it is claimed, more closely re- 

 sembles the human touch than that of any. other automatic 

 player. This is accomplished by means of a "Diaphragm Pneu- 

 matic," which, when in 

 the act of striking, be- 

 comes filled with air, 

 giving a light, resilient 

 touch, closely resem- 

 bling that of the hu- 

 man fingers. Other 

 players use a con- 

 trivance run by a tel- 

 lows system that is 

 worked by an exhaust, and when a note strikes the air is com- 

 pletely withdrawn. [Wilcox & White Co., Meriden, Connecticut.] 



THE SNOEER TO BE EFFECTIVELY RUBBERED. 



There are plenty of men who will not display the slightest 

 interest when you tell them that the rubber industry now 

 amounts to nearly half a billion dollars a year, and that in the 

 United States alone its annual value is over $200,000,000, who 

 will become keenly interested when you tell them that some in- 

 ventive genius has devised a little rubber contrivance that pre- 

 vents all snoring. 



This is a device made of soft wool, interwoven with rubber 

 threads, that goes over the top of the head, down under the 

 chin and is held in place by a band going around the back of the 

 head. The softness of the wool and the elasticity of the rub- 

 ber are intended to conduce to the comfort of the wearer, while 

 the rubber in the band being slightly stretched when it goes un- 

 der the chin, is intended to keep the snorer's mouth quietly and 

 decently closed, and thus conduce much to the comfort of the 

 wearer's neighbors. 



City people whose bedroom windows open out on air-shafts 

 on which many other bedroom windows also open, will be de- 

 lighted to know that these snore-suppressors can be secured at 

 40 cents retail; so that at a little expense and with a discrim- 

 inating distribution of these little devices, they may pass the 

 night in peace and comfort.

MENDING HOLES IN RUBBER BOOTS. 



If there is anything irritating in human experience, it is the 

 sensation of the hunter or fisherman who has paid $6 or $7 

 for a pair of rubber boots, and then run a sharp point through 

 the foot or the leg. Naturally he does not care to throw 

 away these boots, and yet to wear them with the water com- 

 ing through the puncture is not particularly agreeable. 



INNER PLATE' 



TAT. AUQ. II, 1903 



Here is a small device which comes in various sizes, as 

 shown by the accompanying cuts, that will relieve the wearer 

 of the boots from his distress. It is called the "Easy-Quick" 

 repairer, and consists of two concave plates which fasten to- 

 gether. The lower plate which goes inside of the punctured 

 rubber has a threaded pivot which projects through a hole in 

 the upper plate. The two are held together with a flush nut 

 without the use of any cement or glue. The inner plate is so 

 thin that it does not irritate the foot or the leg, and the re- 

 pair can be made in a minute. 



These repairers come in various sizes and cost only a few 

 cents. A key to tighten the nut is supplied with them.

•'SIMPLEX' BREAST PUMP. 



A new breast pump, thoroughly sanitary, has just been put 



on the market. It is of convenient size, and the glass is made 



^v— ^ to fit the breast comfortably. The reservoir 



/ is easily kept clean, and is so shaped that 



/ , its interior can be reached by the finger. 



^ The rubber bulb is attached to the glass by 



a screw thread and can be easily removed 



for cleaning. This pump is absolutely new 



w '' and promises to be much used owing to its 



ll|gl|! simplicity in construction and its comfort 



"^ in use. [Whitall Tatum Co., 46 Barclay 



street. New York.] 



NEW USE FOR RUBBEE HOSE. 



New uses for rubber hose are being dis- 

 ivered every day. Here is one that bids 

 lir to be employed extensively. The old 

 system of removing old paint by scraping it 

 off was exceedingly laborious and wasteful 

 of time. That method has been superseded 

 by the application of paint removers, in 

 liquid form, which attack the oil which 

 holds the paint to the surface. These paint removers can be ap- 

 plied by hand, but by the use of rubber hose they can be applied 

 much more rapidly and easily. The liquid paint remover is 

 put in a tank where it is kept under the pressure of compressed 

 air. A pipe, the inner end of which is submerged in the remover, 

 extends through the wall of the tank and is fitted to a rubber 

 hose of any desired length, at the end of which there is a spray 

 nozzle. When the governing valve is opened, the compressed 

 air forces the liquid through the hose and nozzle, and it strikes 

 the painted surface in the form" of a spray.
