THE INDIA RUBBER WORLD 



[March 1, 1920. 



A RUBBER GLOVE WITH KNUCKLES. 



Surgeons' gloves are now made with allowance for the 

 knuckles, thus, it is claimed, preserving the "cuticle touch" in 

 all its sensitiveness and acuteness at the same time that a per- 

 fect-titting sanitary hand covering is provided. These "KnuklfiT" 



gloves give free 

 and easy finger 

 action, free cir- 

 culation of the 

 blood, and elim- 

 inate tension on 

 SiRcEuNs "K.svKi.FiT" Rubber Gi.ove. the finger tips. 



Oversize gloves are no longer required, with their awkward 

 wrinkles and folds. It is also claimed for these gloves that 

 they retain their shape and may be sterilized more times than 

 most other rubber gloves. (The Lincoln Rubber Co., Akron 

 Ohio.) 



A REINFORCED BLOW-OUT PATCH. 



A new kind of blow-out patch is constructed with a layer 

 of wire mesh inserted in the center, embedded in a layer of 

 cushion stock that is vulcanized to fabric on each side. This 

 permits flexibility without separation, while the wire insert 

 resists pressure evenly and affords protection to any rupture 

 ill the tire casing. It ^extends to vviihin three-quarters of an 

 inch of each 

 edge with at 

 least five plies 

 of fabric cover- 

 i n g the wire 

 completely. This 

 patch contains 

 from five to nine 

 plies of high- 

 grade fabric, the 

 number being •■?;asv-On" Holder. 



determined by the size. 



With these patches is used the "Easy-On" holder, which hooks 

 them around the casing and holds them securely to the side- 

 wall while putting on. The holder is removed after inflation.

PNEUMATIC LIFE SAVING GARMENT. 



A convenient inflatable garment intended tcj be used as a 

 life-preserver is shown in the accompanying photograph. This 

 garment, however, may 

 be worn underneath or 

 over the clothing, as de- 

 sired. Three seconds is 

 said to be sufficient time 

 for inflating, and, as the 

 garment weighs only ten 

 and one-half ounces and 

 folds up compactly when 

 not inflated, the whole 

 may be carried in the 

 coat pocket. 



When desired, this 

 garment can be luted 

 into coats, vests, bathing 

 suits, knitted sweaters 

 and Jerseys, or any 

 other wearing apparel. 



The inner tube of the 

 Griffin pneumatic life- 

 saving garment is of rubber, and it is claimed that the speedy 

 inflation valve took three years to perfect. (The Griffin Manu- 

 facturing Co., 113 State street, Boston, Massachusetts.) 



RUBBER SPLICE INSULATOR. 



.\ new kind of insulator for electrical splicing is ex]ikiiiied 

 by the accompanying drawing. It consists of a small rubber 

 cap, long and narrow, with an enlarged mouth which permits 

 it to be stretched over end-splices at outlets, in junction boxes 

 and the various fittings of conduit, cable and metal molding 

 work, on terminal splices in motor leads and on splices in 

 fixtures. The use of this device is said to eliminate grounding 

 and entirely prevent short-circuits at end-splices in outlet 

 boxes, etc.

size, but a larger size is planned to accom- 

 modate larger splices such as three No. 14 wires or two No. 10 

 wires spliced, etc. (The Elasticap Co., Hoboken, New Jersey.) 



AN AUTOMATIC SAFETY TIRE VALVE 



.■\n automatic safety tire valve that "whistles 

 when it's had enough" air has a large hole 

 through the valve stem, from end to end. The 

 inside or check valve seats on top of the stem 

 and is held securely in place, making an air- 

 tight seal by the joining of the stem with the 

 pressure regulator. When sufficient air has 

 been pumped into the tire, a whistle announces 

 the fact, from which the name of the device 

 is derived— the "Whistler." (The .Automatic 

 Safety Tire 'Valve Corp., 176S Broadway, New 

 York Citv.) 



Two new valves for toy balloons, on which "Whistler 

 applications for patents have been made, con- 

 sist in the main of perforated metal caps, within which are 

 positioned disks of paper. One has three inward-turning tabs, 

 enclosing two disks. (E. J. Dunbar Co., 28 West 22d street. 

 New York City.) The other has a tri-perforated metal insert, 

 enclosing a single disk. (Howe 

 liaumann Balloon Co., 187 

 Murray street, New 'York City.) 



New squawker ends for toy 

 balloons, turned from wood, 

 slightly ribbed for ornament, 

 and varnished lightly, include 

 two general forms. One ha^ 

 a simple flange over which to 

 fasten the balloon and the 

 other, in addition to the flange, 

 has a groove in which the 

 fastening may lie. (Novelty 

 Turning Co., Norway, Me.) 



"PARCO" INNER TIRE. 



The inner tire shown here "" 



is of sponge rubber to replace the usual pneumatic tube. In this 

 case it is shaped and enclosed in fabric. The "Parco" inner tire 

 comes in dififerent sizes to fit all makes of standard size casings.
