Title: Improvements in automatic friction drop stamps
IPC: B28B1/04
Filed: 1946-08-24
Abstract: 629,655. Power hammers. MASSEY, Ltd., B. & S., and WELLS, L. W. Aug. 24, 1946, No. 25359. [Class 83 (iv)] [Also in Group XXVI] In a friction-lift drop-hammer comprising a trip 12, operating lever 57, cam rod 39 rotatable by the movement of the tup, a rotatable and reciprocable control-valve 25 supplying air under pressure to a relay valve 29, the provision of ports in the relay valve casing for the venting of air leaking thereto but which are automatically closed when air is admitted under pressure, of back-lash free operating connections from the tup and the operating lever to the control valve, and of means for varying the stroke of the tup, when operating continuously, independently of the height to which it is raised when not operating continuously. The tup is connected to a board 13 raised by rollers driven from a motor 15 and during its movement bears on and moves a cam-bar 38 secured to a rotatable cam-rod 39. The lower end of the rod 39 is coupled to a member 61 adjustable to and from the machine frame by a hand wheel 64 against the action of a spring 62. This device, together with a universal coupling 40 at its upper end allows the lower end of the cam-rod to be moved to and from the tup. The rod 39 is connected through a cable 41 to the control valve 25 so that reciprocation of the tup causes a reciprocation of the valve against the action of a spring 48 which also serves to keep the cam-bar 38 pressed against the tup. An extension 42a of the spindle of the valve 25 carries a sprocket-wheel 51 connected by a chain 58 with a sprocket 54 on a spindle 55b to which is secured a lever 55 adjustably connected to a lever 57 operable by a pedal 22 so that movement of the pedal causes a corresponding rotation of the valve 25. A source of compressed air is connected by a pipe 18 to the tupoperating mechanism through a chest 24 housing the control and relay valves 25, 29 (see Group XXVI), and by a pipe 20 to the hold-up gear control valve. The latter valve is operated in its casing 66 by a pivoted lever 67 acted on by a cam 71 secured to the spindle 55b of the sprocket 54. As the tup reciprocates vertically, the control valve is given a proportional horizontal reciprocation and causes a reversal of the movement of the tup when either set of ports 27 or 28 is closed by the valve. The horizontal position of the valve at which this occurs may be varied by a rotation of the valve due to the actuation of the pedal 22. Thus the position of adjustment of the pedal connection 55, 57 varies the length of stroke, while the hand wheel 64 varies the point of pick-up without materially altering the height of release of the tup. The supply of compressed air to a cylinder controlling the hold-up device is controlled by a cam 71 secured to the spindle 55b. Specification 289,519, [Class 83 (iv)], is referred to.

A vent line 44 connects the tank 18 either to a high point in conduit 42, as shown, or to the valve casing, the tank 18 having an air vent cap 38. In the system shown, engine coolant during warm-up conditions flows by way of the pump 14, through valve 16 and conduit 46 to the tank 18 from which it returns to the engine by way of conduits 50, 40, thus by-passing the cooling section of the radiator. When sufficiently warm, the coolant is directed by valve 16 through the conduit 42 to the radiator 12 from which it returns to the pump via conduit 40.
