 ruT, 



A RUBBER-SET WAGON WASHER. 



N inventive genius associated formerly with one of the oldest 

 rubber manufacturers in the country has invented a rubbcr- 



,.i,..r i,,r vehicles.

It consists of a rubber cup-shaped 

 bulb provided vifith 

 a coupling at one 

 end so that it may 

 be attached to a 

 hose, while the 

 other end is open 



and clear, with inturned rul)ber teeth. \ sponge is inserted in 



this open end, and the water turned on. the pressure of which 



bends the rubber teeth outward so that they take a tisht grip 



on the sponge. 



This washer has various ob- 

 vious advantages. In the first 



place, the sponge can retain no 



grit to scratch the varnish, because 



the force of the water passing 



through it necessarily cleans away 



all grit. It has no metal parts to 



come in contact w-ith the varnish, 



and there is no waste of water, as 



all the water used must pass 



through the sponge, and be ap- 

 plied at the spot that is being 



cleaned. Moreover, there is no 



splashing, as is usually the case 



where a sponge is used in the 



hand. The mechanism is simple 



in construction, the sponge being 



easy to insert and to remove when the pressure of the water 



is relaxed. [Rulil^erstt Co.. Newark, N. J.] 



RUBBER GARMENTS TO REDUCE SUPERFLUOUS FLESH. 



The world can be divided into two classes— the thin who want 

 to get fat, and the fat who want to get thin. For the first class 

 there is little hope; but for the second class there are sundry 

 avenues of escape. One recently opened is a medicated rubber 

 garment, or more properly, a series of such garments of various 

 styles and sizes, intended to cover the male or female anatomy — 

 in whole or in part — invented by a New York woman doctor. 

 The accompanying cuts show some of these garments. The state- 



4Kk. 



ment is made that if these garments are w-orn by people with 

 undue flesh — particularly if they walk or take other exercise 

 while wearing them — the superfluous avoirdupois will grad- 

 ually melt avi-ay. The further statement is made that these gar- 

 ments can be worn with perfect safety, and that they are endorsed 

 by leading physicians. [Dr. Jeanne Walter, 45 West 34th street, 

 New York.]

A PNEUMATIC TIRE IN SECTIONS. 



One great trouble with the pneumatic tire is the fact that 

 all the air is in one tube and when anything goes wrong 

 with that tube, even a little puncture the size of a tack point, 

 out goes the air and away goes the tube. Now some inventive 

 people in Trenton, New Jersey, have devised a pneumatic tire 

 that is composed of distinct sections — 6 to 10 sections making 



a complete in- 

 ner tube — and 

 each of these 

 sections will 

 have 30 cells 

 running its 

 length, so that 

 the complete 

 tube is com- 

 posed of from 

 180 t o 30O 

 small tubes; 

 anyone of 



Ikr^jrxv /Jf^\ _:: ' M^^ punctured and

""^jVo^^.r ''jr^,^^^ '"S '^^ others. 



It is called 

 "t h e Roberts 

 Sectional 



Pneumatic Tube" and it embodies the old proposition of divid- 

 ing a lar.a;e space into several smaller spaces like the tubular 

 boiler and water-tight compartments in a ship. 



Each section — molded \\\\\\ one end closed and the other 

 open, as is shown in Fig. 1 — is put in a patented machine filled 

 with compressed air, and at the same time the open end is 

 sealed, by a 

 cap of rubber 

 and fabric be- 

 ing vulcanized 

 over it. W'hen 

 taken from 

 this machine 

 it appears as 

 in Fig. 2. The 

 V-shaped cut 

 has spread 

 apart, thus al- 

 lowing for the 

 expansion o f 

 the rubber. 



The neces- 

 s a r y number 

 of these sec- 

 tions are now 

 cemented to- 

 gether, forming a ring the exact size of the inside of the 

 shoe. To put on a wheel take the ring of sections, place in 

 a shoe, then with an ordinary tire-iron or C-clamp draw 

 the points of the V together and push the beading of the 

 shoe under the rim. The pressure of the V is sufficient to 

 hold the shoe on tlie rim. 



It can be seen at a glance that blowouts are impossible. 

 A nail would not penetrate more than three or four of these
