A NIPPLE FOR SPLIT-PALATE NURSING. 

 Tlie difficulties with which doctors and nurses and parents 

 have to contend in nursing babies who are unfortunate enough 

 to have split palates have been lessened by the invention of a 

 special nipple, shown in the accompanying illus- 

 tration. Tliis device has as its base a nipple 



much like the ordinary kind, 

 a soft-rubber shield, knowr 

 shield." The whole fits over 

 bottle. (F. A. Hardy & Co..

[RESTONE "HOLDFAST" PATCH STOCK. 

 .^n improvement of the "Holdfast" patch which has been on 

 the market for some time is now being put out. The stock is 

 preiiarcd in sheet form so that it may be cut as small as desired 

 to repair tubes of any size. Previously the patches came already 

 cut in special sizes, which made it necessary for dealers to carry 

 several of these. (Firestone Tire & Rubber Co.. Akron. Ohio.) 



THE "STADCO SEE-SAFE" WINDSHIELD WIPER. 

 -\Mybody who allows his windsliield to become misty or clouded 

 with rain and snow must be far 

 from civilization with its multi- 

 plicity of windshield cleaners. 

 Every few weeks a new model 

 appears, and practically all of 

 them employ rubber on the 

 squilgee principle for cleaning 

 the glass of the shield. The one 

 pictured here is adapted for at- 

 tachment on the top edge of the 

 wind-shield, but pivots in such 

 a way as to make it possible to 

 operate it straight across the 

 shield or in a semi-circle. The 

 diiTerent parts of this device, on 

 which the trade-mark is copy- 

 righted, and on some features of 

 wliicli a patent has been applied for, are plainly indicated in the 

 drawing. The attachment is not expensive and comes packed 

 by the dozen in a box for counter display. (Stadeker Metal 

 Specialty Co., 358 West Madison street, Chicago, 111.) 



TITAN V/ORK SHOE. 

 A new work-shoe, pro- 

 duced at a medium price, 

 while selling for less 

 money than the ordinary 

 leather shoe, has some 

 advantages over the lat- 

 ter which the wage- 

 earner should appreciate. 

 The shoe has an upper 

 of extra heavy duck, 

 reddish-brown in color. 

 The soles and heels are 

 of fiber and rubber of 

 superior wearing quality. 

 The shoe is blucher cut, 

 with one-piece bellows 

 tongue, has a broad high 

 toe with tip, and is an 

 attractive, rugged, easy 

 shoe which should com- 

 mend itself to 

 chusetts.) 



RUBBER USED WITH THE "BALKAN" BED. 



In The Indi.v Rubber World for March 1, 1918, v.as a short 

 account of the work of the Surgical Requisites Association of 

 England in the present war and a letter from Dr. Philip Schid- 

 rowitz, the chemist and writer, telling about some of the uses 

 found for rubber in modern surgery and nursing. Some of these 

 inventions had been made 

 by members of the associ- 

 ation, and these included 

 the "double Balkan" hos- 

 pital bed, of which a sketch 

 has been obtained and is 

 now presented herewith. 

 It is known as the S. R. A. 

 "Williams" double Balkan, 

 and is the invention of two 

 members of the associa- 

 tion. A clever arrange- 

 ment of pulleys and a 

 traveling framework make 

 it possible to raise and 

 lower a patient at will, or 

 his head or feet independently of each other. What is called a 

 girth mattress is used with this bed, made in sections which 

 may be taken apart as required for treatment without moving 

 the patient. Rubber sheeting, tubing for feeding and irrigation, 

 feeding bottles, etc., are used in connection with this bed. (The 

 Surgical Requisites Association, 17 Mulberry Walk, Church St., 

 Chelsea, S. W. 3, London.) 



HEAT-TIMING CLOCK FOR MOLD WORK. 



The necessity of accurate timing of heats in mold work sug- 

 gests that the device here illustrated may be of interest. In 

 laboratory work it could be util- 

 ized in carrying out chemical 

 tests according to standardized 

 methods. 



It closely resembles an alarm- 

 clock in appearance, but in real- 

 ity it is an interval-timer that 

 can be set for any interval b 

 tween fifteen seconds and tw 

 hours. At the end of the peric 

 for which it has been set, the 

 alarm rings and the clock stops.

RUBBER AND FIBER WELT. 

 In the making of hand or machine welt shoes, a narrow strip 

 of leather is commonly used for the welt. Some years ago J. N. 

 Moulton invented a welt of rubber, for which he claims that a 

 waterproof seam would result from its use. Recently he has 

 designed a combination welt, which consists of a strip of rubber, 

 skived at one edge, and reinforced for one-half its width with 

 a thickness of heavy duck. This fabric holds the stitches whicii 

 might tear through a strip not thus reinforced, and the free edge. 

 being elastic, enables the welt to lie flat when stretched around 

 the toe, no matter how small the diameter. (Plymouth Rubber 

 Co., Canton, Massachusetts.) 



SPUN GLASS INSTEAD OF RUBBER RINGS. 



.\ccording to "Die Zeit," a firm in Aussig, Austria, has suc- 

 ceeded in producing a kind of spun glass which answers the 

 same purpose of cork and rubber rings in closing bottles. The 

 invention is said to be very cheap and likely to be of importance.
