Abstract
461,859. Toggle linkage. KLOCKE, W. June 20, 1936, No. 17239. Convention date, Oct. 25, 1935. [Class 80 (iii)] [Also in Group XXII] A toggle linkage press is constructed to provide a " dwell period during the application of pressure to the work, and this through a large angle of movement of a driving crank. In the diagram of Fig. 3 an angle of 90‹ is shown for the movement of the crank 24, Figs. 1 and 3, during which period the slide is comparatively stationary. Toggle levers 20, 21 are attached to a connecting-rod 25 articulated to the crank 24 which is mounted on a shaft 37 driven through gearing 33, 30, 35. The lever 21 is attached to a fixed pivot 40 and the lever 20 to an elbow 42 integral with a knuckle lever 15 carrying the tool slide 12. The amplitude of movement of the toggle levers during a 90‹ movement of the crank is indicated by the angle c. A clutch is provided between the shaft 37 and gear wheel 35 and this may be of the oscillatory key type with the key so located that its movement from engaged to disengaged takes place during the 90‹ movement. U.S.A. Specification 2,014,234 is referred to.
