Definitions

  • a holder for inserting fastening elements with transversely extending heads, such as nails and the like, into a setting device from which the fastening elements are driven by an explosive force transmitted by a piston is provided by an elongated strip formed of a particular material with a selected thickness so that the head of the fastening element can punch out the material of the strip when it is driven into the target material.
  • Holes are provided in the strip to receive and hold the shanks of the fastening elements and the strip is partially perforated at positions spaced outwardly from and on opposite sides of the holes so that a portion of the strip spaced located inwardly from the perforations can separate from the strip when the fastening element contacts the strip with the punched out part forming a washer on the shank of the fastening element.
  • the edges of the strip are provided with spaced recesses for feeding the strip through the setting device.
  • the present invention is directed to a holder for feeding fastening elements, such as nails and the like, into a setting device from which the fastening elements are driven by a piston, and, more particularly, it concerns an elongated strip-shaped holder in which the shanks of the fastening elements are secured in longitudinally spaced holes and in which the holder is formed of such material and dimensions that the fastening element can punch through the holder when it is driven into the target material.
  • the setting device uses a piston for driving the fastening element into the target material
  • the piston when a fastening element is to be positioned within the barrel of the setting device, the piston must be located in its starting or firing position so that the fastening element can be inserted.
  • the fastening element holder is provided as an elongated flat strip whose material and thickness are selected so that the strip can be punched out by the head of the fastening element as it is driven from the setting device by the explosive force transmitted by a piston.
  • a belt-shaped strip which can be produced by very simple means, fastening elements of any length can be secured.
  • the fastening element is driven through the holder strip, a portion of the strip is punched out by the head of the fastening element'and the punched out part serves as a washer.
  • the head on the fastening element With a diameter slightly greater than the diameter of the piston it is possible to form the hole punched out of the holder strip so that the piston can pass through it without any interference in completing the driving of the fastening element into the target material. Accordingly, as the piston drives the fastening element into the target material and also as the piston is retracted into its firing position, there is no problem of frictional engagement between the piston and the material of the holder strip.
  • the holder strip is formed of an aluminum alloy to insure light-weight and good machining properties.
  • Another advantageous feature of the invention is the partial perforation of the band in a ring spaced outwardly from the hole containing the fastening element and in alignment with the periphery of the fastening element head so that a satisfactory punching effect can be insured when the fastening element is driven through the holder stip.
  • the longitudinal edges of the strip are provided with spaced recesses which facilitate the feeding action.
  • FIG. 1 is a view, partly in section, of a setting device for driving fastening elements into a target material with a holder strip, in accordance with the present invention, feeding the fastening elements into position for the driving operation;
  • FIG. 2 is a perspective view of the forward end of the setting device, shown partly in section, with the holder strip containing the fastening elements aligned for insertion into the setting device.
  • a gun-like setting device for driving fastening elements 16, such as nails, studs and the like, into a target material 11.
  • the setting device has a pistol-grip type handle 2 containing a trigger 3 for actuating a firing pin 4, in a known manner, so that the firing pin strikes a cartridge 6 mounted within a cartridge chamber 5.
  • a base plate la is provided which rests against the target material 11 when the fastening element is being inserted.
  • a barrel 7 extends through the base plate la and the barrel has a rearward part 7a located behind a forward part 7b in the firing direction of the device.
  • a piston guide 8 is provided for guiding or directing the rear or head end 9a of the piston.
  • the piston guide is moved forwardly, that is, toward the muzzle end of the device, by means of a handle 12 against the action of a tension spring 14 which extends between the piston guide 8 and the base plate la.
  • Friction elements 13 are provided on the head end 9a of the piston 9 so that the piston guide engages the piston and by means of the spring 14 returns the piston into its firing position.
  • a holder strip 17 with the fastening elements 16 held in a serially spaced arrangement is inserted into a channel which extends through the base plate la of the device perpendicularly to the barrel 7. From the inlet side of the channel 15 to the barrel, the channel has an increased dimension in the axial direction of the barrel so that it can accommodate the form and length of the fastening elements to be introduced into the barrel. This feature of the increased length of the channel 15 can be particularly noted in FIG. 2.
  • the holder strip 17 has perforated portions 17u disposed symmetrically on opposite sides of and spaced outwardly from the holes containing the fastening elements.
  • the perforations 17:: are aligned below the periph eral edges of the heads of the fastening elements. Further, spaced recesses or notches 17b are provided in the longitudinally extending edges of the holder strip 17 for engagement with means for feeding the strip through the channel 15 in the setting device, however, since these means for feeding the strip are known and do not form any part of the invention, they are not illustrated.
  • the perforations 17a are spaced inwardly from the side edges of the holder strip 17.
  • the perforations 17a for each hole are spaced apart in the elongated direction of the strip 17 from the perforations for adjacent holes so that a transversely extending portion of the strip is located between the perforations about adjacent holes.
  • the trigger When a fastening element 16 is to be driven into the target material 11, the trigger is actuated and the ignition of the cartridge causes the generation of gases which afford an explosive force to the piston for driving it forwardly toward the muzzle end of the device.
  • a recess 9b in the forward end of the piston shank 90 engages a projection 16b on the head of the fastening element and in combination with the hole in the holder strip guides the fastening element through the forward part 7!; of the barrel 7.
  • the guidance afforded by the holder strip becomes superfluous.
  • the portion of the holder strip surrounding the shank 16c of the fastening element is punched out by the head 16a of the fastening element and provides a washer on the fastening element shank. After the washer is separated from the strip the trans versely extending portion remains between the longitudinally extending strip edges. Since the diameter of the fastening element head 16a is greater than the diameter of the piston shank 9c, the piston shank can pass through the hole formed in the holder strip without experiencing any resistance or interference. After the completion of the driving operation, the shank 9c of the piston can be easily retracted through the hole in the holder strip since there is no frictional engagement to be overcome. The perforations 17a in the holder strip 17 assure that the strip is completely punched out as the fastening element passes through the strip.
  • Perforations 17a are provided on both sides of the hole supporting the fastening element shank 16c so that it is possible to use the holder strip on both sides.
  • holder strips have been used with nails having shank diameters in the range of 2.5 to 5.5 mm.
  • the width and thickness of the holder strips depends on various conditions, one example is a holder strip with a width of 14 mm and a thickness of 0.5 to 1.5 mm.
  • aluminum alloys have been indicated as materials for forming the holder strips, it will be appreciated that other materials, such as brass, steel and other metals, could be used.
  • a holder assembly for supplying fastening elements into the barrel of a setting device so that the fastening elements can be driven into a target material by means of a piston driven by an explosive force developed within the setting device
  • the holder assembly includes a flat elongated strip having a plurality of holes therethrough spaced apart in the elongated direction of said strip and a fastening element positioned within each hole
  • each said fastening element includes an elongated shank having a first end and a second end with the first end arranged to be inserted first into the target material and a head extending transversely laterally outwardly from the circumferential periphery of the shank at the second end thereof
  • the improvement comprises that the shank of each said fastening element is secured within one of the holes in said holder strip adjacent the first end thereof and spaced for a considerable axial length of the shank from its second end so that the head of the fastening element is spaced from said holder strip, said holder strip having a width greater than the diameter
  • a holder assembly as set forth in claim 1, wherein said holder strip is formed of an aluminum alloy.
  • a holder assembly as set forth in claim 1, wherein said fastening elements have a shank diameter in the range of 2.5 to 5.5 mm and said strip has a width of about 14 mm and a thickness in the range of 0.5 to 1.5
  • a holder assembly as set forth in claim 1, wherein said strip has notches located in the longitudinally extending edges thereof with the inner surfaces of said notches spaced laterally outwardly from said perforations, and said notches arranged for engagement with means for feeding the strip through the setting device.
