THE INDIA RUBBER WORLD 



[June 1. 1915. 



A SPIDER WITH RUBBER FEET. 



The blast buffer is an invention for the protection of plate 

 glass windows in buildings liable to vibration from blasting or 

 other causes, it is made of bent 

 steel n ids, to the four ends of which 

 are attached flat steel pieces 2 inches 

 long and 1 inch wide, and c< 

 w iih rubber pads. It is held in place 

 i the plate glass bj wire rods 

 w s in the win- 

 di hi frame, iusl eni mgh tension be- 

 pplied ti n sist \ ibration It is 

 li alike to the inside or out- 

 side of the window, or in extreme 

 cases, or where the window is oi 

 i . ptional size, it is used on both 

 idi . with tin- pads directly opposite each other on the glass. 



A NEW SIMPLEX BATTERY-METER. 



The No. 4 is a new type of battery-meter especially adapted 



foi the use ol automobilists in testing the strength of batter) 



„ solutions The use of the rubber bulb is in drawing .i 



1 sufficient quantity of the solution into the battery-meter 



ft J to do,,t the hydrometer, the reading being taken by 



noting the point on the scale in tile stem at which the 



^| hydrometer floats A fully charged battery should 



show a densitj of 1,280, and would be exhausted at 



1,150; one which reads 1.250 when fully charged is 



exhausted at 1,100. The solution in batteries which 

 show at full charge readings higher than 1,300 or lower 



than 1,250 should be diluted, in the one case, and in 

 tin' other, strengthened by the addition of a solution 

 of sulphuric acid. This new type is 10J4 inches in 

 length, and is furnished in a wooden box with a hinged 

 cover. Kxtra or worn parts, including the rubber 

 bulb, can be supplied at any time. [Simplex Hydro- 

 meter Co.. Newark. New Jersey | 



A NEW RAJAH SPARK PLUG. 



The special features which distinguish the new waterproof 

 Rajah spark plug from the regulation device of its kind iiiaiitl- 



~ factured b\ this company, are the 



. JlMji ' ' the , hp 



*T»nii r j terminal on the cable and the 



protecting part screwed to the plug bushing — 

 this latter being made of a hard rubber sub- 

 stitute of high heat-resisting properties, I he 

 company guarantees this plug — which is fur- 

 nished in all the standard sizes, with a Rajah 

 regular terminal to fit any cable, or with fer- 

 rule terminals where a sample of cable is sup- 

 plied — to be absolutely waterproof. | Rajah 

 \uto-Supply Co., Bloomfield, New Jersey.] 



RUBBER TOP LIFTS FOR WOOD HEELS 



According to a late issue of the "Boot & Shoe Reporter," the 



idea ol a half or full Louis heel with rubber top lift has been 

 developed to a considerable extent in connection with the manu- 

 facture of women's shoes, and concerns making rubber heels 

 are producing these lifts for the wood heel makers. Additional 

 elasticity over the old style wood heel with leather lift, with 

 consequent increased comfort, is claimed.

TIRE ALARM. 

 American rights have been secured in a French device known 

 as the "Cri-Cri," which is designed to notify motorists of the 

 softening of their tires. One end of a steel strip comes in con- 

 tact with the side of the tire, the other is held fast in a clamp 

 that hooks under the rim and is braced against the felloe of the 

 wheel. When the tire becomes soft the strip buckles, making a 

 sharp, metallic noise. [S. S. Sender. Box 308, Rolfe. Iowa.1 



THE DU-FLEX SOLIi WITH THE -RFSISTOE TIP. 



I be manufacturers oi Snowflake Du-Flex s,,ie* have brought 



out a novelty in this Connection in the form of a white sole 

 with a black "double wear" toe made 



of tough, fibrous 1 1 impound This 



tip is not veneered, but is a part 

 of the sole, extending through its 

 entire thickness, the \ ulcani: ation 

 of tin' curved, welded union insur- 

 ing a joint which the makers guar- 

 antee- to remain intact and not to 

 pull apart. Du-Flex soles may be 



applied to the shoe with the same short stitch that is used on 

 the leather sole | Avon Sole Co., Won, Massachusetts 



NEW MILLS FISHING SPECIALTIES. 



A new phantom minnow has appeared, slightly in advance of 

 the season for black bass, for which it is especially recom- 

 mended, but just in time 

 for pickerel fishing, in 

 which its use will be 

 appreciated. It is made 

 of sjlk. coated with ruh- 

 CU bet. in sizes from 1.J-& 

 to 5 inches long, ami retails at 

 from 35 to 75 cents, being ob- 

 tainable with brown spots, blue, 

 silver, with light green stripes and 

 in imitation of whitebait. 



\nd tor the fisherman whose 

 line is inclined toward distracting 

 entanglements, an improved "re- 

 leaser" is now being offered, the 

 simplicity and practical nature of 

 which is suggested by the illus- 

 tration. This shows the wide- 

 rubber hand under which the tip 

 of the rod is inserted and which holds the rod firmly while the 

 releaser is being raised to the detaining twig. Then the rod is 

 withdrawn, a slight pull on the cord cutting the twig and free- 

 ing the line. [William Mills & Son. 21 Park Place. New York] 

 THE STUB-PROOF TIPPED RUBBER SOLE. 



A new tip has been introduced in connection with Goodyear 

 "All Weather Tread" soles, which is called the Stub-Proof. This 

 tip is of fiber and rub- 

 ber and is made an 

 integral part of the sole 

 by vulcanization. so 

 that it cannot crack off, 

 a possibility that pre- 

 sented itself in the case 

 of the old style leather- 

 tipped rubber soles. It 

 is also claimed for it that it will not wear awav as rapidly as the 

 leather toe, because of its resilient composition. [The Goodyear 

 Tire S: Rubber Co., Akron, Ohio.] 



"Nodelay" is a new puncture repair solution. It is described 

 as an emulsion, not a filler, and it is poured through the valve 

 stem into the inner tube, on the entire inner surface of which it 

 forms a thin membrane which, it is claimed, prevents leakage of 

 air due to punctures. [Nodelay Manufacturing Co., Chicago.] 



"Bn vet" is a new outdoor game of more than ordinary fascina- 

 tion. It is played on the lawn with a ball and rubber-headid 

 mallets, and as its enjoyment depends neither upon unusual skill 

 nor athletic practice, a wide field is open to its introduction.
