Definitions

  • a hand-held power tool for driving a retaining clip into fastening engagement with a stud comprising means for engaging the stud, means proximate to the stud engaging means for engaging the clip, and power means for moving' the clip engaging means relative to the stud engaging means whereby to drive the clip into engagement with the stud.
  • This invention relates to power tools and is directed more particularly to a hand-held power tool for urging a retaining clip into engagement with "a stud whereby to fasten the clip to the stud.
  • a feature of the present invention is the provision in a hand-held tool of gripper means for engaging a stud and clip disposed on the stud, drive means for operating the gripper means, and control means for initiating operation of the drive means.
  • FIG. 1 is an elevational view, partly in section and partly cut away, showing one 4form of tool illustrative of an embodiment of the invention
  • FIG. 2 is an elevational view of a portion of the tool shown in FIG. l, but shown in position for a clip setting operation;
  • FIG. 3 is an enlarged detailed view showing the jaws of the tool at the beginning of a clip setting operation
  • FIG. 4 is similar to FIG. 3, but shows the tool jaws upon completion of a clip setting operation
  • FIG. 5 is a perspective view of a set clip.
  • the illustrative device includes a body 2 comprising a grip portion 4.
  • a cylinder 6 in which is disposed a piston 8 having a rst piston head 10 at one end and a second and larger piston head 12 at the other end.
  • Each piston head 10, 12 may have a groove therein for the retention of a sealing ring 14.
  • the interior of the cylinder 6 has an enlarged portion 16 to receive the second, or larger, piston head 12.
  • the second piston head 12, being larger in diameter, has a surface area greater than the first piston head 10.
  • a piston rod 18 is attached to the piston 8 and extends forwardly therefrom (leftwardly as viewed in FIG. l).
  • a barrel member 22 Secured to the cylinder 6, as by a connecting means, herein illustrated as an internally threaded collar 20, is a barrel member 22 having an elongated bore 24 which receives the free end of the piston rod 18.
  • a jaw member 26 Pivotally mounted on the barrel member 22 is a jaw member 26 having at one end drive clip engagement means 28 and at the other end a cam surface 30 engageable with a cam surface 32 on the piston rod 18.
  • the barrel member 22 also includes a bore 36 which receives a stud S (FIGS. 3 and 4) on which a drive clip C is to be set.
  • the barrel member 22 and the jaw member 26 are provided with opposed bores 38, 40 respectively which receive a coil spring 42 which biases the jaw 26 outwardly from the barrel 22, as shown in FIG. 2.
  • the drive clip engagement means 28 includes a slot 44 adapted to receive a flange portion F (FIGS. 3 and 4) of the clip C.
  • Proximate to the slot 44 is at least one magnet 46 herein shown embedded in the jaw member 26 and forming part of the walls of the slot 44. The magnet assists in locating the ange portion F of the clip C in the slot 44 of the jaw member 26. Magnets may also be used, though not shown in the illustrative example, proximate to the bore 36 to facilitate locating of the stud S in the stud receiving bore 36.
  • the cylinder is provided with bores 48, 50 which serve as pressurized fluid inlets and also as exhaust outlets, depending upon which side of the piston head 12 is pressurized.
  • a uid conducting tube 52 is connected to the tool to provide pressurized uid, such as air, for the cylinder 6.
  • Pivotally mounted on the body 2 is a trigger mechanism 54 which may be spring biased to the inoperative position 54 shown in phantom in FIG. 1.
  • a switch 56 including a plunger 58 engageable by the trigger.
  • the switch 56 operates a valve, not shown but located in the grip portion 4 and operative to conduct pressurized fluid from the tube 52 to either of the inlets 48, 50 permitting exhausting to atmosphere of the inlet not in communication with the tube 52.
  • the trigger 54 is normally in position shown in phantom in FIG. 1 between operating cycles.
  • pressurized air or other uid from the tube 52 is directed by way of the abovementioned valve through the bore 48 to till the area within the cylinder bounded by the two piston heads 10, 12.
  • the piston 8 is forced toward the back end of the cylinder 6, or right end as viewed in FIG. 1.
  • the bore 50 is open to exhaust air which otherwise might be trapped behind the piston head 12.
  • the operator engages a clip C with the clip engagement means 28, locating the flange portion F of the clip in the slot 44 of the jaw member 26.
  • the magnets 4.6 assist in facilitating the picking up of a clip by the tool without manual operations on the part of the operator, other than handling the tool.
  • a metal support member M is to have a panel member P attached to it.
  • the support member M is provided with a headless threadless stud S, as by welding or adhesive means, and the panel member P is provided with a hole H (FIG. 3) which receives the stud S.
  • the operator places the free end of the barrel member upon the stud, the stud being received by an enlarged portion L of a key-hole slot and by the bore 36 in the barrel member.
  • the clip C which now has the stud disposed in the enlarged portion of the key-hole slot (best seen in FIG. is in position for being driven onto the stud.
  • Cutting edges E disposed about the key-hole slot of the clip are thereby caused to cuttingly engage the stud S so as to securely aix the clip C to the stud S whereby to prevent escape of the panel P from between the clip and the support M. If it is desired that the panel P be attached snugly to the support M, the ,tool need only be pressed firmly against the clip during the setting operation. The clip, being of leaf-spring conguration, tends to urge the panel retained thereby toward the support.
  • the tool Upon setting of the clip, lthe tool is withdrawn from the stud and clip and the trigger released by the operator.
  • the trigger returns to the inoperative position, causing the bore to exhaust and the bore 49 to receive pressurized air, whereby to return the piston to its rearward position in preparation for another cycle of operations.
  • a tool for securing a leaf spring type clip on a stud adjacent to its base the clip having an upturned end and a slot extending generally normal thereto, the slot having an enlarged opening for initially receiving the stud and provided with opposed cutting edges extending therefrom and spaced for thereafter transversely engaging and gripping the opposite side surfaces of the stud, a body portion having a clip engaging end formed with a recess to axially receive the stud when loosely inserted through said enlarged clip opening, a jaw pivotally mounted on the body portion for movement between an open position wherein a recess in the jaw receives said up-turned end of the clip and a closed position to force said edges of said slot to cut transversely into the stud and aix the clip securely thereon, the jaw being swingable about a fulcrum positioned in the body portion transversely of said clip engaging end and spaced therefrom, and iluid pressure means in said body por tion under the control of an operator for causing the jaw to close and thereby force the clip
  • a tool asset forth in claim 1 wherein the axis of said jaw fulcrum is offset laterally lfrom the axis of the stud receiving recess in the body portion by substantially the distance of the jaw recess therefrom when said jaw is closed, and surfaces of the body portion and said jaw are disposed to be engaged to limit jaw closure whereby the clip is not distorted during its securement to said stud.
