THE INDIA RUBBER WORLD 



[September 1, 1913. 



A PORTABLE STEAM TIRE VITLCANIZER. 



It is a great convenience when a repair on a tire is to be 

 vulcanized to have the vulcanizer in the tool box of the car 

 where it can be applied in a moment. The "Positive" Vul- 

 canizer is certainly easy to carry about as it is small in size and 

 weighs only 3 pounds. It is a steam vulcanizer and can be 

 used on the shoe when the tire is inflated, without even jacking 

 up the wheel, and can also be used on the inner tube. It will 

 be noticed by the illustration that there are two sets of com-

partments ; one is for water and the other is for gasolene or 

 other fuel. The operation is simple and quick. The proper 

 amount of each fluid is inserted in the proper compartments, and 

 enough gasolene ignited to burn 20 minutes. Then, allowing 10 

 minutes for the repair to cool, the motorist can go on his way. 

 While steam does the vulcanizing, it will be seen that the steam 

 compartments are open at the top, so that there is no pressure 

 and therefore no liability to injury on this score. Where the 

 inner tube is to be vulcanized it can be laid over an inflated 

 casing or on the special block which is furnished with each 

 outfit. (Positive Tire Vulcanizing Co., D.ivenport, Iowa.) 



RUBBER BALL SUGGESTION FOR THE RETAILER. 



A recent entertainment given by the University of Cincinnati — 

 the institution upon whose legal faculty ex-President Taft 

 until recently held the post of honor — aff'ords an excellent sug- 

 gestion to dealers in large rubber balls, especially such as may 

 have a surplus of these on their hands which they do not 

 wish to carry over to the Christmas holiday season. 



A market for such may be discovered by keeping an eye on 

 the doings of the high school or college in the dealer's home 

 city, and when the students are found to be contemplating an 

 entertainment of one sort or another, giving them the suggestion 

 as carried out in the institution aforesaid. In brief, the idea is 

 this — that a Greek dance be introduced into the program, 

 either as an enir 'actc or at some appropriate point where play 

 or program may be interrupted. 



The players in the Cincinnati entertainment were girls, the 

 most comely of course in the class, and in order to minimize 

 expense each of these girls fashioned for herself a Grecian tunic, 

 — a simple robe costing very little. .\ny young woman who is 

 able to dance at all can quickly acquire the rhythmic round 

 dances of the Greeks, given to an accompaniment of appropriate 

 music. The more young women taking part, the more kin, 

 friends, admirers of course will come to see; and hence the 

 greater the net results of the entertainment. Therefore this 

 particular university dance was composed of as many per- 

 formers as the stage would conveniently allow. 



In order to make the dance unique. Prof. Joseph Harry, who 

 introduced it in connection with the "Frogs of Aristophanes" — 



the first performance of this play in two thousand years — 

 equipped each of these pseudo-Grecian maidens with a big rub- 

 ber ball, handsomely gilded over by rolling in a bath of gilt 

 paint. In the course of the dance the balls are tossed high in 

 air. then caught in the two hands by the girls, every so often. 

 Of course the balls are too big not to be caught every time; 

 nor are they thrown so high as to be missed. 



It is very obvious that the use of these gilded balls is open 

 to a variety of permutations and combinations. For instance, 

 the dancers in the front and in the rear rows can throw their 

 balls into the air simultaneously, and then the dancers in the 

 intervening rows can go through the same e.xercise. By alter- 

 nating different rows, and then by alternating individuals, there

is opportunity for great variety of movement and effect. In 

 the dances given in Cincinnati a great many of these combina- 

 tions were used, but it is not necessary to state just what ones, 

 as anyone devising such a dance can suit himself. This feature 

 was a great success w-hen given during the college exercises 

 above mentioned, and this success can be duplicated anywhere 

 else under similar circumstances. So any dealer in rubber toys 

 who has an overstock of large hollow rubber balls can work out 

 this suggestion for what he may find in it. 



A NEW TIRE FILLER CALLED •BETTERN-AIR." 



It would be possible, of course, to fill most of the pages 

 of this publication each month with descriptions of sub- 

 stitutes for the pneumatic tire, for they are legion: but oc- 

 casionally one comes along that seems more promising than 

 its thousand and one companions A new substitute recently 

 brought on the market is called "Bettern-Air." It is the 

 invention of a German chemist who has been working on 

 it for the past six years. This "Bettern-.\ir" composition 

 is intended to take the place of the inner tube. It is made 

 in rolls of various sizes to fit various tires and is cut to the 

 proper length. It is then inserted in the outer shoe and a 

 small wed,ge piece put at the point where the two ends come 

 together. The tire is then ready for use. The manufacturers 

 claim that they have given it two years' test, with extraordi- 

 nary results. They say that it has been used in tires where 

 after 4.500 miles of travel it shows no effects of wear. The 

 claim is not made that it is good for racing tires — it is not 

 lively enough in its resiliency for a 60-miIe clip — but for 30 

 miles an hour and anything under that it is said to be as 

 resilient as air. It is being marketed by The Galvanizing Co., 

 of Philadelphia, and the agents in the Xew York district are 

 Bailey & Johnson, of Brooklyn.
