THE INDIA RUBBER WORLD 



[September i, 1904. 



noise, but the great resounding qualities of the metal, to- 

 gether with the peculiar shape of the horn, changes this 

 sound to a deep mellow tone, which will penetrate the at- 

 mosphere for quite a distance. The tone is peculiar to itself, 

 and can be distinguished from that of any other horn." Be- 

 sides, the horn is provided with a special device for attaching 

 it to the dashboard, and is equipped with a flexible metallic 

 tube which is made airtight with rubber packing. On the end 

 of the latter there is a large rubber bulb which, when com- 

 pressed, forces the air out of the metallic tube, bringing it in 

 contact with the reed, thus causing the sound. [Imported by 

 Emil Grossman, No. 298 Broadway, New York.] 



THE " N. I. R." AUTOMOBILE PAIL. 

 As a result of much experimenting a new automobile pail 

 has been placed upon the market which combines many desir- 

 able features. This pail 



is made of rubber, folds 



up into compact space, 



taking practically no 



room, is light, appears 



to be very durable, and 



is convenient, as it can 



be operated with one 



hand. It can be used 



either for water or gaso- 

 line. It can be used 



like an ordinary pail, 



having a snout and a 



strainer at the top, or 

 it can be used automatically. As the bottom of the pail 

 comes to a point it can be lowered inside the inlet to 

 tank. There is an automatic valve that catches on the side of 

 the inlet and opens the pail, letting out the contents. The 

 raising of the pail closes this valve and the flow stops. Auto- 

 mobilists speak very highly of it. [National India Rubber Co.,

SILK LINED SEAMLESS RUBBER GLOVE. 

 This glove, designed primarily for use in surgical operations, 

 in consequence of having fingers reinforced with silk, has 

 greater durability, and while in use 

 is less apt to be damaged by the in- 

 struments, than unlined gloves. 

 The silk lining makes it possible 

 to wear these gloves for a longer 

 time, as it prevents trouble from per- 

 spiration of the hands, which is very 

 objectionable when the skin comes 

 into direct contact with rubber. 

 The lining keeps the skin of the 

 hands in excellent condition, which 

 makes these gloves especially val- 

 uable to those operating surgeons 

 whose skin shows a tendency to be 

 affected by eczema. The fingers of 

 these gloves are left half unlined in 

 order not to lessen the acute sensi- 

 tiveness of the surgeon's touch. The gloves, notwithstanding 

 their silk lining, are pliant and supple, and cling to the hands 

 as closely as unlined gloves, the palms and backs only being 

 covered with silk material, while the other places are left free 

 and therefore retain their elasticity. This is the invention of 

 Professor Dr. Zweifel, and is the subject of a recent German 

 patent— D. R. G. M. 219,391. [Phil. Penin Gummiwaaren- 

 Fabrik, Actiengesellschaft, Leipzig-Plagwitz, Germany.] 



NEW REPAIR TAPE FOR MOTOR TIRES. 



A new article of tire repair tape is made of specially woven 

 duck and the best yellow rubber friction. The use of this 



tape is a very simple mat- 

 ter. The outfit includes 

 square rubber patches. 

 These patches can be 

 moistened in gasoline or 

 naphtha, placed on the 

 puncture, the tape wound 

 around the tire and rim 

 and pulled taut, and then 

 the tape is slit for about 18 

 inches and tied tight. This 

 tape is made in two widths : 

 2 inches wide for large machines and narrower for runabouts.

MORE ABOUT THE HOLLOW BACKED COMBS. 

 In the description given in this department last month of 

 the " Revelation " line of hard rubber combs, mention was 

 omitted of the method by which their distinctive feature is 

 given to these combs. It appears that the combs are made in 

 halves, the two

sections being 

 then joined to- 

 ge t h e r. To 

 make the dies 



so accurate that the two parts of a comb can be adjusted to 

 each other so that the tooth halves will fit together perfectly 

 is certainly a delicate and ingenious bit of work. Even fine 

 tooth combs are made by this method, as shown in the illus- 

 tration herewith, which relates to a comb 4 inches in length — 

 No. 150 in the manufacturers' list. [Harburg Rubber Comb

MILLER'S RESILIENT TIRE CORE. 

 The tire core herewith illustrated is intended to be slipped 



into the outer cover of a detachable pneumatic tire, instead. of 



an air tube, or it may 

 be placed within a 

 single tube tire. If 

 there should be punc- 

 tures in the outer 

 cover they will not 

 interfere in any way, 

 as the core supplies 

 the resiliency ; the 

 casing is for wear, 



and not to hold air. The interior of the core is divided into 



cells by diaphragms spaced quite 



closely, the spaces between them 



being divided through the center 



by partitions extending from the 



rim to the tread. The elasticity 



of the rubber, both under com- 

 pression and tension, is thus 



taken advantage of, and, as there 



is no air pressure, punctures 



have no effect on the tire, which 



is said to be perfectly proof 



against breaking down. This 



core has been applied thus far 



principally to the detachable 



tire casings of the Fisk and Goodyear tires. [Charles Miller, 



No. 309 North Water street, Binghamton, New York.]
