Abstract

3178. Hopkinson, J., and Hopkinson, &. Co., J. Feb. 15. Plug cocks; oscillating disk valves.-In a valve for blow-off cocks and the like, two valves are combined and so connected that one valve is opened before and closed after the other so that it is subjected to no rush of fluid during opening or closing. In the example shown, a disk A perforated at B bears upon a seat C and can be turned by the spindle E to open the passage D. In combination with it is a hollow plug cock H which is turned by the spindle J, which engages a square hole in the disk A, in the following manner : A cotter K is loosely fitted in a slot in the spindle and engages a slot L to rotate the plug. On the spindle being turned to open the valve, the cotter rotates the plug until, when the plug is fully open, it impinges upon the cam-surface M and is withdrawn. Further rotation of the spindle rotates the disk only, and a stop G determines when that is fully open. In closing, after the disk valve is fully closed the cotter is moved outwards by the cam-surface O to re-engage the slot L and rotate the plug. In modifications, there may be used, instead of the plug, a rotary disk valve or a lift valve operated by screw threads operated from the upper disk.
