Definitions

  • the bell crank pivoted at 93 to a movable floating element or slide 95 which is constrained to move vertically in a guide 91 in the frame 59.
  • the long arm of the bell crank is shown at 99 and its lower end is pivoted at the knee joint to the toggle arm I3.
  • the pivoted point I02 between the bell crank 9I and the toggle arm is displaced from the pivot point IOI between the toggle arm 13 and the connecting rod 15. This reduces some complications that arise in making a three-way pin joint.
  • the shorter toggle arm is shown at I29 extending up toward the table, being linked at knee joint I3I to the connecting rod I33 which is pinned at I35 to the crank disc 131.
  • the crank disc I31 is driven from the main shaft I39 through a gear train consisting of a worm-and-wheel combination MI, and a spur gear combination I43.
  • the usual flywheel is shown at I45.
  • the toggle arm I29 is oscillated around the fixed center I I9. Above the table I I3, the arrangement is as already described in connection with the other forms.
  • a toggle press comprising a frame having a platen and a ram slide on opposite sides of a work gap, a toggle linkage having a fulcrum located in the frame toward one side of the work gap, said toggle linkage comprising a link pivoted on said fulcrum and providing a swinging knee joint, a link having one end pivoted at said knee joint and extending past the work gap, and a pivot carried by said last-named link having a sliding connection with the frame on the ramslide side of the work gap, said last-named link also having an operative connection with the ram slide and being in the form of a bell crank, one arm of which passes the work gap and the other arm of which arches thereover.
  • a connectin link between said crank and said toggle arm adapted upon rotation of the crank to oscillate said toggle arm and said knee joint, a substantially vertically movable floating element having a freely movable connection with the frame, and a toggle link pivoted to said knee joint, said toggle link having a connection with said movable element and having an additional operative connection with the ram slide.
