Ky. The drawings show a quick action device for testing feedvalves. Fig. 1 gives a side view of the device attached to a consists of a body A, a clamp yoke B, a 5^-in. screw C, a handleD and cap screws E. Fig. 2 is a top view and Fig. 3 shows theclamp yoke B when in position for releasing the valve. The pinsF are for guiding the valve to position on the face of the body A. In operation, the yoke is raised as shown in Fig. 3, the valve isplaced over the pins F and against a 1/16-in. gasket. The yokeis then placed in the position shown in Fig. 1 and the tighteningof the screw C causes the yoke to pull the valve against the faceof the body A. The sides of the yoke are slotted to allow forlongitudinal movement. A slot is cut across the corner of the -S E £ ^ B, ^^^ So/ for Scre^ C hReyof\^e Through Fig. Valve Test Rack body, which permits the yoke to revolve as soon as it is releasedsufficiently to clear the valve. The J^-in. inlet and outlet pipes aretapped into the lower side of the body. The drilled ports arethoroughly tinned to prevent leakage. The device is made ofmachinery steel and is amply heavy to withstand shocks.
