THE INDIA RUBBER WORLD 



[January i, 1900. 



GOODRICH CIRCULAR ERASER. 



The making of a compouud that will result in good service 



in an eraser is far from being 

 the simplest problem in the rub- 

 ber industry. An eraser which 

 has yielded good results for ink 

 or pencil, and which is espec- 

 ially adapted to typewriter work, 

 is shown in the accompanying 

 engraving. These erasers are 

 packed one dozen in a box and 

 one gross to the carton. [The B.

THE "TUBE core" GOLF BALL. 

 New patterns of golf balls continue to be produced, particu- 

 larly in Great Britain. Among the latest is that termed the 

 " Tube Core." This is made without any 

 hard core, the material beneath the cover 

 being entirely formed of one length of 

 rubber tubing rolled under high tension. 

 It is claimed that by this method the 

 flight of a cored ball is combined with the 

 putting qualities of a gutta-percha ball^ 

 while hacking or splitting is reduced to a 

 minimum. The effort to increase the durability of cored balls 

 seems, by all reports, to have had a considerable amount of 

 success in this particular instance, for the tube core ball has 

 withstood without injury the severe test of lengthy play.

A RUBBER TEAPOT SPOUT. 

 It is very natural that a tea-drinking race such as the Eng- 

 lish should invent certain appliances fortheir needs that would 

 not find any particular use among those having the tea habit in 

 only a slight degree. Such an invention is the Mandarin pour- 

 er. This is really an artificial teapot spout, made of white rub- 

 ber, designed to fit over a badly molded or broken nosed tea- 

 pot, the pourer being so curved that the liquid throws away from 

 the spout in a concrete stream. In order to obviate any taste 

 or smell of the rubber, it is the custom to soak it in strong tea 

 for some 24 hours. It is then applied to the teapot, and is said 

 to have a quite general use, not, perhaps, among those who 

 have the finest of tea services, but where pennies must needs 

 be counted with care. The appliance is registered, but is not 

 patented, and is to be found in rubber stores throughout the 

 United Kingdom, in none of which is the inquiring foreigner 

 likely to be told who manufactures it. 



AIR CUSHION TYPEWRITER FEET. 

 The device illustrated herewith is the result of experiments 

 made by a practical operator, who for a long time had been 



studying ways and means to less- 

 en the rum blingand hollow sound 

 lontinually made by typewriters 

 when in use. It is claimed for 

 thissimple pneumatic device that 

 It will increase the life of a type

wear and tear both upon operator 

 and machine, the slipping on or marring of costly desks, and 

 the rumble of a machine when attached in a roll top desk.

RUBBER DEVELOPMENT IN PERU. 



■^ 



SE.XOR DON FELIPE PARDO.the new Peruvian minister 

 to the United States, arrived at New York on December 

 21 from Colon, aboard the Royal Mail steamship Orinoco, with 

 his bride, who formerly was Senora Teresa Barreda de Pardo, 

 daughter of his paternal uncle. Sefior Pardo speaks English 

 and several other languages fluently. Another passenger by the 

 same steamer was his brother, Sefior Don Juan Pardo, whose 

 mission is in connection with the completion of details for the 

 forming of an important and extensive company for the work- 

 ing under a single control of some large rubber concessions in 

 southeastern Peru, which are understood to be of very great 

 value. The organization of the new company has been practi- 

 cally consummated, but a more definite statement at this time 

 cannot be made public. The two gentlemen named are broth- 

 ers of the president of Peru. 



FACTS ABOUT COLORADO RUBBER. 



A COMPANY in New York, expert in the extraction of rub- 

 ber from shrubs, have lately carried out very exhaustive 

 experiments in their own laboratories with the Colorado " rab- 

 bit weed." They were able to get from the weed just as it was 

 gathered i per cent, in weight of rubber ; after the dirt had been 

 shaken off of the weeds and the leaves removed they got 3 per 

 cent, of rubber. They further went very carefully into the cost 

 of gathering the weed, and, finding out how many individual 

 weeds it took to make a pound, and figuring exactly how many 

 pounds a smart man could gather, working 10 hours a day. A 

 careful analysis of the cost of gathering and the amount of rub- 

 ber that could be extracted proved to them conclusively that 

 there was not enough rubber present in the weed to pay for the 

 cost of gathering it, let alone extraction. 



THE GUAYULE FACTORY AT TORREON. 



TV /r ANY newspapers in Mexico and a few in the United 

 ■'•'•' States have given much space to the Guayule rubber 

 plant now being established in Torreon, Mexico, by the Con- 

 tinental-Mexican Rubber Co. (New York). Without cata- 

 loguing the many wild statements made, the following may be 

 in order. The plant will not cover 23 acres, as has been pub- 

 lished, but will consist of a building for storage of a shrub and 

 extraction of rubber, some 400 feet long and 300 feet wide, one 

 story high. This happens to be situated on a 100 acre plot 

 purchased by the company, not because they intended to cover 

 the land with buildings, but because land was cheap down 

 there and they were able thus to get a right of way to two dif- 

 ferent railroads. The statement that John D. Rockefeller, Jr., 

 is either president or director is an error, as the president is 

 Mr. E. B. Aldrich, as chronicled in the October i, 1905, issue of 

 The India Rubber World. 



Inflated Footballs. — Where footballs are used for display 

 purposes, either indoors or in show windows, but especially 

 in the latter case, they should not be inflated, as deterioration 

 is sure to result. Light and heat has a bad effect upon foot- 

 ball bladders, cycle inner tubes, and other articles of thin rub- 

 ber, which should preferably be kept in a dark place in a tem- 

 perature of not over 70 degrees. A football inflated and hung 

 near the ceiling of a store room, as they are frequently seen, 

 from the tendency of heat to rise is subjected to a higher tem- 

 perature than exists at the counter level and in a short time 

 will suffer from its effects. — Sporting Goods Dealer.
