Description: |
"My invention relates to improvements in presses, and relates more particularly to that type of press used for various purposes in machine shops and similar places, and one of the objects of my invention is to rapidly relieve the pressure of the ratchet-hand wheel against the screw, so that the said wheel may be then readily turned by hand to elevate or lower the screw. Another object of my invention is to provide counter-balanced means to remove certain actuating means for the ratchet-hand wheel out of the path of movement of this wheel at certain times..." |
