THE INDIA RUBBER WORLD 



[August 1, 1917. 



tubing held in place over the point of the shoulder bone by a 

 lining of leather secured all around both sides of the tubing 

 and padded in the middle. Another rubber tube goes under 

 the arms, and this and the laced collar hold the pad in position. 

 It is claimed that even the severest blows on the shoulders, thus 

 protected, arc hardly noticeable. The same idea, a round rub- 

 ber pneumatic ring, is used in a knee pad with equally good re- 

 sults. [Sell Sporting Goods Co., Canton, Ohio.] 



A WHITE-SOLED PAC. 



A boot calculated to stand the hardest wear, and give comfort 

 and long service to the outdoor worker is here illustrated. It is 



a combination of rubber foot and 

 leather top. The latter is made 

 of a specially prepared waterproof 

 leather, and is provided with a 

 bellows tongue, so that the wearer 

 is assured dry feet, even when 

 standing or walking in deep snow 

 or slush. The upper is of heavy 

 coated duck with ribs to strength- 

 en it. The white sole has a 

 rolled edge, and is made of a spe- 

 cial compound which the makers 

 use for their tire treads; (these 

 treads bearing a guarantee of 5,000 

 miles). The top and upper are 

 joined by four rows of heavy 

 stitching and a loop is formed by 

 a continuation of the 

 backstay. This is an 

 excellent boot for 

 heavy outdoor work 

 in winter. [Converse

MULFOHD APPAHATUS FOB APPLYING CAEREL-DAKIN SOLUTION. 



An apparatus for applying the Carrel-Dakin solution, widely 

 known through its use in the war for irrigating wounds, has 

 lately been perfected by the firm of manufacturing and biologi- 

 cal chemists which also makes the .'^o'.ution itself. 



A series of individual connecting tubes makes possible the 

 treatment of several wounds at one time from the same reser- 

 voir, the special thick-walled rubber tubing with very fine bore 

 permitting only a minimum loss in temperature of the solution 

 as it passes through these connecting tubes. Absolute control 

 of the amount of solution flowing to each individual instillation 



tube is maintained by observing through the individual sight 

 drips and regulating by means of metal clamps. The collaps- 

 ible stand-furnished with the outfit has adjustable collars attach- 

 able to any size bed post. This apparatus can also be adapted 

 for the "Murphy drip" and for hypodcrmoclysis. [H. K. Mul-

THE TRI-CO UNIVERSAL RAIN RUBBER. 



Many of the devices for cleaning tlie windshield of a motor 

 car in a storm are stationary, forming an unsightly attachmsnt 

 in clear weather wheii their use is not demanded. This simple 



little device is designed 

 to be quickly and 

 easily attached and de- 

 tached from a two- 

 piece shield. It con- 

 sists primarily of a 

 traveling section which 

 is mounted in and 

 slides along the open- 

 ing between the upper 

 and lower halves of 

 the w-indshield, holding 

 on to the edge of the 

 glass by a channel. 

 Two arms project 

 from this section, one 

 to each panel of the 

 shield, and on each 

 arm are two rubber 

 strips set edgewise, so 

 that when moved 

 across the glass sur- 

 face, water is pressed off by the close fit of rubber to the glass. 

 To prevent possible scratching of the glass, the rivets holding the 

 various parts together are topped with celluloid where there is 

 any chance of contact. This windshield cleaner is made in five 

 models, to fit practically any type of two-piece windshield. [Tri- 

 Continental Corporation, Sidway Building, Buffalo, New York.]

METAL BARREL WITH RUBBER GASKET. 



A new type of metal barrel has a 6-inch opening and, also, 

 a special removable head which can be made absolutely 

 liquid-tight by the action of a series of buckles, or bolts, 



compressing a rubber 

 gasket 3/16-inch round, 

 vulcanized to form a 

 complete circle, hollow 

 at the center. The illus- 

 trations are sectional 

 views of the barrel, the 

 upper one showing the 



buckle in an inoperative fTv^ 

 position, preparatory to [■ '! | 

 removal of the head, 

 and the lower showing 

 the buckle in position 

 for making the closure. 

 The further these 

 buckles are turned, the 

 tighter thej' squeeze the rubber gasket, thus eft'ectively seal- 

 ing the barrel. The removable head allows this barrel to be 

 used economically for the shipment of powders such as red 

 or white lead, or heavy oils, paints, varnishes and greasy 

 substances difficult to clean out of the ordinary barrel.
