THE INDIA RUBBER WORLD 



459 



for carrying and purifying drinking water for the troops. These 

 bags, which were designed by the quartermaster's department, 

 are of double texture material, the outside of heavy khaki duck, 

 similar to army cloth, and the lining of a thinner material. This 

 is made up into cylindrical bags about the size of a barrel and 

 of a capacity of about 50 gallons. There is a metal hoop at the 

 top hinged to close like a traveling bag, and, at the bottom, four 

 taps where the contents can be drawn off into canteens. These 

 bags are filled with water from any available source, and by 

 means of chemicals are purified and rendered fit for drinking 

 within a few minutes, and this water is transported in these 

 heavy bags with other stores of supplies needed by the army. 



"CORALINE" ERASERS. 



A new series of rulibcr erasers of an attractive coral hue. 

 doubtless suggesting the above trade name, has recently been 



put upon the mar- 

 ket. These eras- 

 ers appeal espe- 

 cially to drafts- 

 men, since their 

 rhomboid shape 

 makes erasure 

 easy without dis- 

 turbing the adja- 

 cent lines or let- 

 ters. The texture is soft and velvety and they are claimed to 

 possess excellent erasive qualities. They are supplied in two 

 sizes. No. 310, small and No. 315, large. [Weldon Roberts 

 Rubber Co., Newark, New Jersey.] 



RUBBER HEEL WITH REPLACEABLE PLUGS. 



A rubber heel employing an entirely new principle as well as a 

 new design, is here shown. Replaceable plugs of white rubber 

 are fitted at three points into the ordinary cushion heel, as seen 



in the illustration, and these 

 plugs keep the heel absolutely 

 level, doing away 

 with the tendency 

 of the usual rub- 

 ber heel to wear 

 down at the 

 edges. The plugs 

 also prevent slip- 

 p i n g, and al- 

 though they never pull out un- 

 less intentionally removed, their 

 movement, in and out, as the 

 wearer walks, gives added resili- 

 ence. When worn down they are easily replaced, without the use 

 of cement, by moistening the base with vaseline or any heavy 

 lubricant and pressing straight down into the heel with any blunt 

 instrument. [Emery Heel Sales Co., Boston, Massachusetts.) 



ELASTIC AUTO-BODY SUPPORTER. 



Long rides in automobiles, while beneficial to tlie health in 

 many ways, are apt to have an injurious effect if the body is 

 not well supported, owing to the continuous jarring of the 

 machine. Women's corsets afford 

 such support, and for men a 

 liractical appliance is no\v on the mar- 

 ket which adequately sustains the 

 back and abdomen against this jar- 

 ring motion, yet affords the absolute 

 .'\uto-Body Supporter" is in the form 

 of a well-shaped elastic band of pink silk-finish thread inter- 

 woven with rubber thread. It is made 6 indies deep, in all 

 sizes. [Sharp & Smith, Chicago, Illinois.]

This 



TOY BALLOON WITH WIRE HOLDER AND HOOKED-DOWN VALVE. 



An attractive novelty is shown in the 

 "Perfection" toy balloon. It remains in- 

 variably upright, waving gracefully on 

 the end of a wire holder, and is held in 

 perfect alinement with the wire by being 

 I firmly hooked down to the valve. The 

 advantage of this holder over the old 

 reed and string variety is self- 

 evident. Also, it is a simple 

 matter to inflate or deflate the 

 balloon by means of the valve. 

 To inflate, ascertain that the valve is 

 open by pushing in gently on the wire 

 ring or hook ; these balloons inflate to 

 7y2 inches in diameter. After inflating, 

 pulling outward gently on the wire ring 

 or hook will tightly close the valve. 

 Then the hook is put through the ring in 

 the holder and hooked into the U bend in 

 the wire under the ring. [The Globe 

 Rubber Co.. Cuvahoea Falls, Ohio.] 



HARD RUBBER PENCIL HOLDER. 



A pencil holder that is practical and convenient for 

 short lengths of pencils is made entirely of hard rubber. 

 The holder consists of a barrel four inches long 

 for regular pocket size, or three inches long for 

 vest pocket and shopping bag size. A tapered, 

 reversible pencil clutch is fitted to one end of the 

 ^j holder and this holds securely either hexagon or 

 ■I round-shaped pencils of varying diameter. 



En XlJ. '^ removable eraser clutch inserted in the 

 ■11 ■■ opposite end of the holder takes a standard 

 IF I KM size erasive tip which is easily renewable. 



i I -B-J These holders are supplied completely 



equipped with pencil and eraser and in 

 various styles, with fancy mountings, if desired. [Vaughn-Upton 

 Co., Inc.. 249-251 Causeway street. Boston. Massachusetts.) 



THE WEILAPHONE. 



A telephone booth shuts out all disturbing sounds but cannot 

 increase the power of the voice coming from the receiver. Both 

 these desirable objects are accomplished, it is claimed, by a simple 



attachment called the 



"Wcilaphone," shown in 

 the accompanying illus- 

 tration, in which the 

 base, ear tips and Y- 

 shaped holders are made 

 of hard rubber composi- 

 tion, connected by soft 

 rubber tubing. The con- 

 tour of the ear pieces in 

 relation to the face is 

 formed and maintained 

 by a copper wire pro- 

 ceeding from the Y 

 piece upward, extend- 

 ing a .-.hL.ri distance in the ear pieces. By means of this 

 wire the instrument is held in place in the ears, rendering un- 

 necessary the use of the hands to support it. When the instru- 

 ment is in use, the terephone receiver is set on a soft rubber cap 

 on the base piece that not only supports the receiver but serves 

 to modify the harsh sounds sometimes incidental to the use of 

 the telephone receiver and to shut out all outside noises and vi- 

 brations, thus bringing the voice at the other end of the wire 

 clearly and distinctly to the user of the 'Weilaphonc." [The 

 Wcilaphone. Inc., New York City.)
