THE INDIA RUBBER WORLD 



[August 1. 1915. 



RUBBER IN BUNION RELIEVERS 



Among the new devices for the relief of foot troubles is the 

 one shown in the accompanying cut, the Wizard adjustable 

 bunion and callous remover and arch builder. This device is 

 worn inside the shoe, being an insole of fine, smooth leather with 

 pockets arranged for the insertion of soft, round rubber pads 

 varying in thickness from one-sixteenth to one-quarter of an inch 

 at the center and tapering to a very thin edge. The illustration 

 - these rubber pads inserted in two of the four pockets, 

 which are supposed to come directly back of the bunion or callous 



place. B) relieving pressure on the joints, the device is supposed 

 not onlj to build up the arch but also to remove callous places 

 and corns from the bottom of the feet. [Wizard Foot Appliance 

 Co., St. Louis, Missouri.] 



THE 'POP OFF" TIRE GAGE. 



In order that tires may give most satisfactory and lasting 

 service various degrees of air pressure are recommended for 

 different loads; and the degree of a tire's infla- 

 tion can only be measured by a tire gage. A 

 simple and inexpensive device of this kind is the 

 "Pop Off" gage, a cut of which is here shown. 

 In use. the indicator is set at the 

 desired amount of air pressure and 

 the air line or pump is fastened to 

 the side of the gage and started. 

 When the pressure reaches the point 

 at which the indicator is set the surplus air ex- 

 hausts. [American Sanitary Lock Co. Indian- 

 apolis. Indiana.] 



THE SOUAWKER BALLOON WITH PATENT VALVE. 



The competition of the cheap hand-made 

 imported toy balloon, which American manufac- 

 turers have never been able to meet, has been 

 eliminated for the present by the situation in 

 foreign rubber manufacture, and home producers 

 are finding readier sales for the higher-grade 

 lines. One of these is the "Faultless" Quality 

 Seamless "Squawker," which is made in assorted 

 colors warranted fast and non-poisonous. Two 

 istinct classes of balloons are included in this 

 line, a light weight for inflating with air, and a 

 heavier weight, chemically treated type for gas 

 inflation. 



A new valve of a practical and simple nature has also been 

 introduced by this company and is used in its balloons where 

 desired, at a very small advance in price over the ordinary 

 variety. This valve does away with the use of the reed stock 

 and requires no sharp instrument to operate it. After inflating 

 the balloon a turn of the valve to the right closes the air 

 tube; to deflate, it i> given a turn to the left. [The Faultless 

 Rubber Co., Ashland. Ohio.] 



\ sanitary device known as the "Renelise" nipple turner i- 

 now on -ale with the drug trade. It is a solid glas< stand, the 

 upper end of which is so formed that rubber nipples of every 

 sort may be turned inside out over it, facilitating their steriliza- 

 tion. [Renelise Xipple Turner Co., 5859 Romaine street, St. 

 Missouri.] 



DRIPLESS POUR REGULATOR. 



I he accompanying illustration shows an entirely new and prac- 

 tical bottle closure and pouring device, the intention of which 

 i- to eliminate the annoyance of dripping which follows the 

 pouring of liquid from bottles, and also to preserve the purity 

 and quality of the bottle's content-. 

 As illustrated this closure is made 

 for an ink bottle and is of hard rub- 

 ber substitute, although the prac- 

 ticability of such a stopper m; 

 rubber, in the bottling of various 

 liquids, is easilj apparent. The stop- 

 per, on which patent has been applied 

 for. has a liquid outlet near the top, 

 also an air vent on the other side. By 

 a turn of the spout to the right the 

 bottle is hermetically sealed, insuring 

 the preservation of its contents. To 

 open the pourout, the spout is turned 

 to the left until it stops, when a pet 

 pendicular stream can be poured from 

 the outlet. The flow can be regulated by 

 to the air vent

HARD RUBBER HARNESS ROSETTES. 



The accompanying illustrations show two late designs in hard 

 rubber rosettes, a very extensive line of which is being turned 

 out by the manufacturers for use in connection with hard rub- 

 ber trimming for fine and medium grades of harness. Hard 

 rubber as a trimming for harness is not a new idea, but the variety 



of designs and extent of its use have rapidly increased since its 

 introduction for this purpose. As a harness trimming it is said 

 to be almost indestructible, outwearing the leather parts in all 

 cases, and it is held in great favor by harness makers and 

 drivers also because of the ease with which it may be cared for.

A molded soft rubber cushion or anti-rattler fitted over the 

 natural teeth has been found effective in absorbing the jar and 

 chattering caused by rapid driving over a brick-paved speedway 

 in racing. This device was worn by Art. Klein in the recent 

 500-mile race on the Indianapolis Speedway. 



There has recently been developed and is being opened to 

 the trade a material having properties between the i irmal lehyde 

 products, such as Bakelite and Condensite, and the best known 

 grades of shellac compositions. This new material is -tyled 

 "Grade 57-Hi-Heet." It has a heat resistance of 250 degrees 

 Fahrenheit, can readily be molded in any form or size, has 

 a tensile strength superior to shellac compositions and a dielec- 

 tric strength of 285 volts at a thickness of 250 mils. The main 

 advantage of this material is high heat resistance, and lower cost 

 than the formaldehyde products. [The General Insula'te Co.,
