  • a resilient section 10 may be provided in the rod 69, if desired.
  • Any suitable means may be provided for swinging the frame l6 about its pivot when the fastening devices l8 are removed, and for that purpose there may be provided a rod or link H which is pivotally connected to the frame, as at 12.
  • This rod is mounted in a suitable bearing 13, and has threaded connection with a gear 74, and with which gear 14 another gear 15 meshes.
  • the gear 15 is provided with a shaft 16 having an an actuating crank to rotate it.
  • a brake device may be applied to the other end of the crankshaft 43 (see particularly Figures 1, 7 and 8), comprising a drum 'l'l that is secured to the end of the crankshaft, preferably by means of a key device I8.
  • a sectional brake band 79 encompasses the drum 1?, and the sections may be pivotally supported, as at 80, an adjusting screw or member 8
  • a spring 82 may be provided between the head of the adjusting device BI and one of the brake sections. This brake is provided for the purpose of preventing overthrow of the crankshaft, and also prevents the shaft from kicking back.
  • the clutch mechanism 58 is of a construction that it will remain normally inactive, but when the foot treadle 5?, is depressed, it will become active to actuate the slide 22, and when the treadle is released, the motion of the slide will be arrested.
  • a suitable latch 83 may be provided (see particularly Figure 11), which latch is pivotally supported intermediate its ends, as at 84, upon a bracket 85 that is secured to the frame 16 adjacent the foot treadle '59.
  • This latch is provided with a shoulder 86 adapted to engage over the treadle 59, as shown in Figure 11. When the treadle 59 is de'ressed, the latch will swing.
  • the latch When it is desired to release the treadle, the latch may be swung into an inoperative position by pressure exerted at 3? on the latch, either by hand or foot.
  • a die member 38 may be connected to the slide 22 by means of clamping mechanism which preferably consists of a member 89 having a recess 90 therein, and a co-operating member 9
  • the die 88 is provided with a reduced portion 94 adapted to be seated and clamped within the recess formed by the portions 90 and 92 of the members 89 and 9
  • An ejector 95 is preferably carried by the die 88, and is held in position with respect thereto, preferably, by means of a spring 96 which engages a collar 91 on the ejector 95. This spring tends normally to project the end 98 of the ejector above the die.
  • An ejector bar 99 is carried by the slide 22, and is of a size to project through slots I in the slide, and beyond the slide, the slots being of a length considerably greater than the height of the ejector bar.
  • This ejector bar may be supported in position in any suitable manner with respect to the slide, preferably by means of pins or members IOI which pass through the ejector bar, and a spring I 02 encompasses each of the pins and serves as a yielding support for the ejector bar.
  • the ejector bar will therefore move with the slide, and is capable of movement with respect to the slide.
  • the ejector bar When the slide is in an elevated position with respect to the bed, the ejector bar will be supported by the springs I02, and when the slide is lowered to cause the die 88 to operate upon the work, the ejector bar will travel with the slide, during which movement the springs I02 will hold the ejector bar against the upper ends of the slots I00.
  • the ejector bar After the work has been formed, and when the slide moves upwardly, the ejector bar will move with the slide, as will also the die 88 and the ejector 95. During this movement the ejector bar will remain in this position with respect to the slide, and will be returned with the slide as the latter 'moves upwardly, until the ends of the ejector bar contact stops or abutments I08 arranged in the path of movement of the ejector bar. As soon as the ejector bar contacts the stops I03, its motion will be arrested, and the slide may continue its movement in an upward direction. This may be accomplished by reason of the slots I00.
  • stops I03 are preferably in the form of screws or bolts adjustably mounted in suitable brackefs I05 secured to the press frame, and after the stops have been adjusted, they may be maintained in their adjusted position by suitable nuts or collars I06.
  • the load and stresses on the press are taken directly by the fulcrum links 46, thereby obviating the danger of causing the frame to spring, or bringing the punch and die out of working alinement.
  • the crankshaft which operates the slide is located a considerable distance back in the frame, and in a position so as not to be in the way of the operator when the pressis operating.
  • the long guiding surfaceof the slide insures better operation of the slide, and the adjustment screw which connects the parts of the slide will always be in a right angle position with respect to the bed, and allows for considerable adjustment of the slide.
  • the entire strain of the press is taken by the fulcrum links which support the operating lever, with the result that it is not necessary that the frame be constructed of heavy material, since it will only be necessary to provide sufficient rigidity to guide the slide and support the crankshaft and moving parts.
  • a frame mounted on a base, a work supporting bed, a reciprocable slide, a die carried by the slide and cooperating with an alined die carried by said bed, a guide for the slide, a driving shaft, an operative connection between the shaft and said slide for reciprocating the latter, means whereby the slide and bed may be inclined with respect to the base, said connection embodying a lever, a fulcrum link for the lever separate from said frame, a pivotal connection between the lever and said fulcrum link, and means forming a rocking connection between the fulcrum link and said frame remote from said bed, whereby the slide, the guide and the work supporting bed will be maintained in proper Working alinement under all stresses of the slide upon the work and in any position of the slide and bed with respect to said frame.
  • a frame In a metal working power press, a frame, a work supporting bed on the frame, a reciprocable slide, a die carried by the slide and cooperating with an alined die carried by said bed, a guide for the slide, a driving shaft, an operative connection between the shaft and said slide for reciprocating the latter, said connection embodying a lever, a fulcrum link for the lever separate from said frame, a pivotal connection between the lever and said fulcrum link, and means forming a rocking connection between the fulcrum link and said frame remote from said bed, whereby the slide, the guide and the work supporting bed will be maintained in proper working alinement under all stresses of the slide upon the work, said driving shaft being disposed in proximity to, in the rear of and spaced from said bed.
