Abstract
321,570. Walker, M. Nov. 26, 1928. No Patent granted (Sealing fee not paid). Presses, mechanical.-Mechanical presses are fitted with friction clutches for disengaging the driving-gear when a predetermined maximum pressure is produced; the clutches being actuated bv the axial movement of a worm under the thrust of the load. In the illustrated form the pressure head is carried on the vertical screwed shaft 8 driven by worm gearing 12, 13 through the forward and reverse clutches 14, 15. At the limiting pressure the worm swings the lever 17 against the action of the spring 16 and thus causes a member 21 to trip the lever 22 to release the spring-influenced member 24 which is linked to the clutches and is returned by the springs upon release to a neutral position in which the forward clutch 14 is disengaged. When the controlling handle 30 is operated to move the member 24 axially to the reversing position, a memher 34 on the press head engages the lever 33 and again releases the member 24 to disengage the clutch 15.
