narrower than its predecessor until the proper amount has been 

 placed on the rim. By setting the cutting knives at an angle the 

 rubber may be cut on a bevel, thus building up the tire on a 

 uniform slant. By using cams of different shape, tires may be 

 l)uilt up with sides of various contours. (Robert McClenathen, 

 assignor to Kelly- Springfield Tire Co., New York City, United 

 Slates patent No. 1,312,491.) 



PRESSURE-CURE FOOTWEAR VULCANIZER. 



In vulcanizing rubber boots the chamber containing them is 

 list freed from air and a vulcanizing medium in the form of a 

 gas (e.g., carbon dioxide) substantially devoid of free oxygen 

 admitted. The chamber is heated by a steam jacket or interior 

 steam coils and the gas is preheated and delivered to the cham- 

 ber under pressure from a storage tank in which it is kept under 



:.\R V 



-Apparatus for this purpose comprises a chamber A, storage 

 tank B for carbon dio.xide, a compression pump C which may 

 also act as a vacuum pump, a pre-heater D and a vacuum pump 

 E. Pipes 8, 1, and 2 serve to pass gas which has entered chamber 

 back to the pump C whence it traverses the preheater again 

 and is thus circulated until the required temperature is reached. 

 It is then sealed in the chamber by valves 9 and 10 and after 

 vulcanizing returned to the tank B by pipes 7, 6 and 11 through 

 the pump C. The compression pump is preferably duplex com- 

 pression ; one which steadily increases the pressure without in- 

 termittent reduction. (W. J. Mellersh-Jackson, 28 Southampton 

 Buildings, London. [American Rubber Co., Boston, Massachu- 

 setts.] British patent No. 128,852.)

A NEW WATER GAME. 



A new water game, similar to cage ball played on land, was 

 recently introduced in one of the Y. M. C. A. natatoriums in 

 Chicago. It is played with a large rubber ball, thirty inches in 

 diameter, the object being to force it through the opponents' de- 

 fense to the goal at the end of the tank.
