 MACHINE FOR PRESERVING PRESSURE IN TENNIS BALLS. 

 /CONTAINERS tor leiiiiis balls and other objects containing 

 ^ fluid under pressure are sealed under pressure by this 

 machine. Each object is placed in a container having a fluid inlet 

 opening, and the con- 

 tainers are placed in a 

 common chamber sup- 

 plied with fluid under 

 pressure, the containers 

 being sealed hermetically 

 when the required pres- 

 sure is reached. As 

 shown, the containers 9* 

 for the balls 9 are placed 

 on a movable platform 7 

 in an annular chamber 1 

 adapted to be closed by 

 a hinged door. Fluid 

 under pressure is intro- 

 duced into the chamber 

 through pipe 21 having 

 a valve 23 and a pressure gage 24, the fluid entering the contain- 

 ers through an opening 35 over which is placed a disk 36 of 

 .solder. The disks of solder on the containers are fused in suc- 

 cession, as the platform 7 is rotated, by an electrically-heated 

 soldering-iron 32 movable through a resilient washer 33 in a 

 dome 31 provided with an electric lamp 38 and a window. When 

 the soldering is completed, the pressure in the chamber is re- 

 lea.sed and the containers are removed through the hinged door.

MACHINE FOR VULCANIZING RUBBER ARTICLES. 



This invention provides means for closing the openings in hot- 

 water bottles through which the core has been removed. The 

 illustration is a side-elevation of the central cross-section of the 

 machine that may be 

 made of suitable length 

 for simultaneously cur- 

 ing a number of articles. 



In operating this ma- 

 chine the movable plat- 

 ens A and B are separ- 

 ated from the stationary 

 platen C, by means of 

 hand-wheels D and E. 

 Steam being applied to 

 the platens, the bottles 

 are suspended, mouth 

 downward, on dowel pins 

 arranged on both sides 

 of the central platen. 



The movable platens are then brought in contact with the cen- 

 tral platen whereby the bottle-ends are cured by heat and pres- 

 sure. (Jeremiah L. Mahoney, New Haven, assignor to The

THRIFT AMONG RAYBESTOS EMPLOYES. 



The Raybestos Savings Club is a novel scheme inaugurated 

 by the Raybestos Co., Bridgeport, Connecticut, its object being 

 to promote thrift among employes and to get a better and more 

 nearly permanent class of men and women operatives for the 

 company. The plan is to deduct from 50 cents to $2 per week, 

 as the worker elects, from each weekly pay envelope to be placed 

 to his account in a local bank. The money will not only draw 

 the regular savings bank interest, but at the end of every year 

 the Raybestos Co. will also pay to each worker who has saved 

 50 cents or more every week an additional 10 per cent of the 

 total amount. About 75 per cent of the employes of the com- 

 pany are taking advantage of the plan, their savings averaging 

 about $2 per week per person.
