THE INDIA RUBBER WORLD 



[April i, 1905. 



THE "faultless" PYROGRAPHY BULB. 

 The interest in pyrography continues to be so well sustained 

 that the production of the outfits used, which formerly were 

 for the most part imported, is becoming more and more of in- 

 terest in the United States. This art, concisely speaking, is 

 simply the drawing of ornamental designs on wood, leather, or 

 other material, with a red hot platinum point. An " outfit " in- 

 cludes, besides the point and its handle, a benzine bottle and 

 a rubber bulb (or bellows), the whole being connected by rub- 

 ber tubing. An alcohol lamp is also used, for heating the plat- 

 inum point. The bulb is at one end, the bottle in the center, 

 and the point at the other end. The cut herewith illustrates 

 a bulb which is seamless in construction, as also is the second-

ary bulb, or air reservoir, which is the larger of the two. The 

 manufacturers of this bulb (The Faultless Rubber Co., Akron, 

 Ohio) state that so far as they know there is nothing similar on 

 the market, the bulbs in the imported outfits being of the 

 seamed or hand made construction, and therefore liable to open 

 where joined together. This is said to be particularly true of 

 the reservoir, which is made of very light stock. Whereas 

 most usually the heat of the point used in pyrographic work is 

 regulated by the slow or quick pressure of bulb by the left hand, 

 outfits are also supplied, involving foot attachments, which con- 

 vert the bulb into a bellows, these bulbs being larger than those 

 used in hand work. 



COMBINED WATER BELT AND FOUNTAIN SYRINGE. 

 A NEW invention relates to a hot or cold water belt and foun- 

 tain syringe combined. The idea is to apply hot or cold water 

 to any part of the body, as desired, the essential feature being 

 a belt of rubber, with a capacity of one gallon, fitted with an 

 adjustable webbed girdle, and covered with Scotch flannel. 

 But however small the quantity of water used, it becomes equal- 

 ized around the body by a slight pressure of the girdle. Thus 

 it may be worn under the clothing, at home, in the office, or on 

 the street. The attachment of a tube to the filling plug ena- 

 bles the Belt to be used as a fountain syringe, if desired. The 



thinking of the citizens of that republic as interested in rubber 

 only in its crude state, but Brazil is a very extensive country, 

 and Senhor Benjamin Gastal, the inventor of the tire illustra- 

 ted herewith, lives far south of the rubber producing district — 

 in Pelotas, a city of 45,000 population, in the state of Rio 

 Grande do Sul. His invention is the 

 subject of United States patent No. 

 772.930. It is, in fact, described as a 

 " vehicle wheel " rather than a tire, but 

 the essential feature is a plurality of rub- 

 ber tubes (not pneumatic), the object of 

 which is to produce a resilient effect. 

 The circumferential portion of the 

 wheel is described in the patent 

 specification as a " rim," the ma- 

 terials used not being referred to. 

 This is in sections, as will be seen 

 from the drawing in cross section, a system of screws 

 being employed to keep them together. These sections 

 are so placed, however, as to render them not liable to 

 contact, with a view to having all vibrations taken up by 

 the three — or more — cushion tubes of rubber, the position of 

 which is clearly shown. They are intended also to reduce 

 noise to a minimum. The members of the rim are referred to 

 as (i) the "spoke section, " (2) a " removable side " (in which 

 engages the larger screw shown in the drawing), and (3) a 

 "tread section," the adjustment of which parts one to another 

 is designed to prevent any one of them from becoming discon- 

 nected in a transverse direction.

invention is the subject of United States patent No. 765 472, 

 granted July 19, 1904, to Dr. Thomas O. Gasaway and Jacob 

 S. Aydetotte. This has been purchased by the Hydro Girdle 

 Co. (Marion, Indiana), who have manufactured the article since 

 September last. The company are incorporated under the laws 

 of Indiana, with $15,000 paid up capital, and the officers are : 

 Fred W. Wilson, president; Fred O. Gephart, vice president; 

 and C. C Gardon, secretary and treasurer. 



RUBBER TIRE INVENTED BY A BRAZILIAN. 



A DISTINCT novelty in the field of rubber invention is a ve- 

 hicle tire designed by a Brazilian. One is accustomed to 



place of the leather trace, with a view to remedying troubles 

 with which every team owner is familiar. Leather traces are 

 expensive to begin with, and, owing to exposure to the elements, 

 hard to keep in proper condition, while 

 any roughening of their surface due to 

 breaks irritates the horse. The cable trace 

 is made of y% inch steel cable, covered 

 with a coating of rubber % inch thick, 

 which gives a surface that is absolutely 

 smooth, and as the trace is round there 

 is nothing about it to injure the horse. 

 There are no stitches and nothing to rip ; there is no stretch 

 and no trouble from the weather; they are strong, light, and 

 flexible, and always look well, the rubber being b!ack. The 

 cable martingale, or choke strap, is practically the same in con- 

 struction, and has all of the commendable features of the trace.
