Abstract

1,067,230. Mechanical presses. S. SHIOKAWA. July 15, 1964 [July 15, 1963], No. 29140/64. Heading B5F. A press comprises a lever 7 connected to a ram 9, and a lever 1 provided with means for oscillating it, the two levers 1, 7 being pivoted on a shaft 3 and provided with means for coupling them together. The coupling means comprises a pawl 13 pivoted on the lever 7 and adapted to co-operate with a notch 15 on the lever 1 unless the pawl 13 is held by a hook 17 operated by a foot pedal 16. The lever 1 is oscillated by a crank 4 rotated through gearing 21, 22 and a pulley 20 by a motor 19. Figs. 4, 5 and 6 (not shown) show two modifications in which the motor and drive pulley are mounted inside the press frame, the oscillated lever (1) in Figs. 4, 5 being of extra length.
