  • FIGURE 13 is an enlarged detailed elevational View partially in section showing the operation of a portion of the wire feeding mechanism.
  • FIGURE 1 the device of this invention is shown in normal horizontal position for use to fasten a strip of panel board B to a wooden stud S. It is with the tool in this position that the directions referred to hereinafter are oriented.
  • FIGURES 2 through 4 the components of the device are shown, the device being in its retracted position ready to form and drive a fastener.
  • the device includes a block lll having at one end a support base l2.
  • the block 10 has a cut out portion 14 adjacent the base 12 in which is disposed a wire support yoke L3.
  • the yoke lo is mounted for pivotal movement in an arcuate groove 13 formed in the support base 12.
  • a pair of longitudinally extending through bores 20 and 2?. are formed in the block lil, the bores terminating at the cut out portion ld.
  • a shoulder 24 is formed on the block it) at the terminal end of the bore 20.
  • a through longitudinal bore 26 is provided in the yoke 16 which is aligned with a bore Z8 in the support base 12 when the device is in the position shown in FIGURES 2-4.
  • a pair of cam rods itl are slidably mounted on opposite sides of the block lil, and each is connected to a cylindrically-shaped drive member 42 by a retaining pin d3.
  • the cam rods d@ each have upper camming surfaces i4 which are operable against the arcuate surfaces 3l on the yoke extensions 36 and against the rear camming surfaces 38 of the cam levers 32.
  • the drive member 42 has extending therefrom a plunger 4o which extends into the longitudinal bore 22.
  • Each of the cam rods 46 is provided with a generally Z-shaped camming member 48 pivotally mounted on a pin 50.
  • the members 4S each have an upper camming surface S2 and a lower engaging surface 54. The upper camming surfaces are positioned to co-act with camming shoulders 55 on block l@ and springs Se bias the camming members 4% to urge the lower engaging surface 54 into grooves 57 formed in the block 1i).
  • a biasing spring 69 normally urges the collar d5 rearward toward the tube 6?.
  • a key 'lil is mounted transversely on the slide member 58 in key slot 72 and the opposite ends thereof extend into grooves 57. Thus, the ends of the key 7d are positioned to co-act with the lower engaging surfaces S4 of the camming member d.
  • Coil springs and 7S surround respectively the plunger dei and the tube 6) normally biasing the drive member 42 and block lit apart.
  • a wire retaining clamp Si?, in the form of a leaf spring is mounted on the yoke :lo and has a projection 82 located adjacent the shoulder 24.
  • the barrel and drive members are enclosed by a pair of telescoping tubes 34 and Se, with tube 84 being secured to the block It) by set screws 3S and the tube 86 being secured to the drive member 2 by set screws 9d.
  • a synthetic rubber handle 92 is moulded onto the tube 86 to provide for gripping of the device.
  • the remote end of the tube 85 flares outwardly to a circular rim 9d which is adapted to peripherally embrace a cylindrical with bore 23 in the base.
  • a synthetic rubber cap g3 is placed on the base l2 and has a Operation and the v will be referred to as forward movement and movement of the drive member away from the block will be referred to as return movement.
  • the upper surfaces of the cam rods du will disengage the rear caniming surfaces of the cam members 32 n and will engage the arcuate cam'surfaces 3l of the yoke extensions 3G. This will cause the yoke to pivot from its position as shown in FIGURE 3 to the position shown in FGURE l0.
  • the wire is sheared against theV edge of the shoulder 24, thus providing a length of wire in the bore 25 of the yoke. This length of wire is the fastener.
  • the length of the fastener formed will depend upon the distance of movement of the slide V58 Iwhen feeding the Wire.
  • the distance of movement of the slide is dependent upon the relative positions of the camming surfaces 4d and the camming members 43. The greater the distance that the camming member moves the slide during theY return lmovement the greater will be the length of wire fed to the yoke.
