Abstract
431,592. Variable - throw cranks. MUIR MACHINE TOOLS, Ltd., WOOD, V. C. N., and OWEN, W., Britannia Works, Sherborne Street, Manchester. March 8, 1934, No. 7388. [Class 80 (iii)] [See also Group XXII] A slotting, shaping or like machine tool has means whereby the length of a stroke of the ram a may be adjusted automatically by the power of the machine during operation. The ram is connected by a link b to an oscillating link c driven by a crank pin i on a disc h which is eccentrically mounted in a block g, driven through spur gears e, f. The block h has worm-wheel teeth engaged by a worm on a spindle connected by a conical gear k to an internally toothed ring n. Normally the ring n rotates with the disc h but when the stroke is to be altered a spring plunger q is forced into engagement with one of the recesses o in the periphery of ring n, thus holding the ring stationary and causing the worm j to rotate the disc h in the block g and alter the stroke. The movement of the disc h and the setting of the stroke may be seen by observing a graduated head t on an extension of the disc through a window v in a cover plate u.
