Abstract: 527,345. Loose ball valves. INDUSTRIA AKT.-GES. April 6, 1939, No. 10823. Convention date, April 12, 1938. [Class 135] A loose ball valve particularly adapted for use with sand blast and like devices has the valve casing 5 bored to receive two aligned flanged nipples 13, 14 which are inserted in pipe sections 6, 7 and secured by union nuts 10, 11. The nipple 14 holds a seating bush 17 against a shoulder 16. The cavity 18 in the casing is offset from the axis of the nipples so that the ball 19 lies out of the path of the fluid stream. By inverting the valve casing, for instance by the handle 22, the ball rolls into the fluid stream which instantly forces it to its seat 20. The ball may be unseated by turning the casing to its original position and depressing a spring-pressed rod 24 retained by a screw cap 28. The rod 24 has a flange 27 normally seating against a packing 29. The nipples may be made of tempered steel or have linings 21 of boron carbide or the carbide of a heavy metal. The ball or the seat may be made of the same materials, or of elastic material, such as rubber. In the form shown in Fig. 3, the valve seat 39 is formed on the nipple 37 which is the actual blast nozzle and the ball 40 can also be pushed into the fluid stream by a spring-pressed plunger 43, the inner end of which is covered by a seal formed as a flexible cap 49 clamped at its outer end by a screw cap 45. This plunger is spaced axially from a similar plunger 42 which pushes the valve from its seat.
