Definitions

  • ABSTRACT In a device for driving fastening elements, such as nails and the like, into a target material, the device has an axially extending bore through which the fastening elements are driven with explosive force by means of a piston and a channel perpendicularly intersects the forward end of the bore for guiding a holder strip supporting the fastening elements through the bore so that the fastening elements can be axially aligned into position to be driven by the piston.
  • the forward or muzzle end of the bore has a larger diameter than its rearward end. The rearward end of the bore serves as a guide for the piston while the forward end guides the fastening elements to be driven from the device.
  • the length of the channel in the axial direction of the bore is sufficient to receive and guide the entire length of the fastening element into the bore. Further, the channel has two pair of guide grooves, one for the holder strip and the other for the head of the fastening ele-' .ment.
  • the present invention is directed to a device for driving fastening elements which are supplied to the device in a holder strip and, more particularly, it concerns the arrangement of a channel within the device for guiding the fastening elements in the holder strip into position in the bore so that they can be driven into a target material.
  • belt-like strips of plastic have been used for feeding the fastening elements into position for insertion by the 'piston and the belt-like strips are fed by means of gear-shaped rotors and are held by the rotors during the driving process. Because these rotors must be positioned on the front or muzzle part of the setting device and extend outwardly from it for a considerable distance, the setting device is difficult to handle and,like the drum-shaped or block-shaped members, it cannot be used in narrow places which are difficult to reach. Further, fastening element holder strips formed of plastic are unsuitable for use in locations where they are exposed to high temperatures because of the sensitivity of the plastic to heat. The problem of using a plastic holder strip is Particularly aggravated where the fastening element device is used in steel mill operations.
  • the forward or muzzle end of the borein the setting device is intersected by a channel extending perpendicularly to the axis of the bore so that a belt-like holder strip supporting the fastening elements in a serial arrangernent can be fed through the bore for locating the fastening elements in position to be driven by a piston mounted within the bore.
  • the channel has two pair of guide grooves spaced apart in the axial direction of the bore and extending in planes perpendicular to the axis 7 of the bore, one for guiding the edges of the holder strip through the bore and the other for guiding the heads of the fastening elements. Further, the dimension of the channel measured parallel to the axial direction of the bore is sufficient to receive and feed the full length of the fastening elements.
  • the present invention it is possible to maintain the holder strip for the fastening elements at a minimum weight andto keep the forward or base plate end of the setting device as small as possible with no additional projections from its forward end, which would impair the versatile applicability of the device. Further, another advantage is that the length of the holder strip for the-fastening elements can be adapted to the individual space requirements involved at the 10- cation where the fastening elements are to be' driven.
  • Another feature of the invention is the formation of the forward end of the bore at a larger diameter than the rearward end so that the rearward end serves as a guide for thepiston while the forward end serves as a guide for the head of the fastening element being driven. Since the forward end of the piston is not in engagement with the forward end of the bore, the friction on the piston is substantially reduced and fastening elements can be used which have a head diameter greater than the diameter of the forward end of the piston.
  • FIG. 1 is a side view, partly in section, of a fasteningelement setting device embodying the present invention and showing a fastening element holder strip po sitioned within the forward end of the setting device; and fastening element holder strip
  • FIG. 2 is a view, partly in section, of the forward or driving fastening elements or nails 16 into a target material 11.
  • the setting device 1 has a pistol grip type handle 2 containing a trigger 3 for actuating a firingpin 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 bore 7 extends through the base plate la and the bore 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 8 For returning the piston to its starting or firing position, the piston guide 8 is moved forwardly, that is toward themuzzle 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 and with the piston guide 8 moved over the head end in its forwardly displaced position, the action ofthe spring 14 on the piston guide returns the piston into its starting or firing position, as shown in FIG. 1.
  • the arrangement for returning the piston 9 into it starting position is shown merely by way of example and the returning action can be effected in a number of other ways, however, since the returning ac,-
  • the rearward part 7a of the bore 7 has a smaller diameter than the forward part 7b.
  • a holder strip 17 for the fastening elements 16 is positioned .within the channel 15 for locating the fastening elements in position within the forward part 7b of the bore-so that the fastening elements can be driven into the target material 11 when a cartridge 6 is ignited.
  • the diameter of the forward part 7b is greater than that of the rearward part and provides a guide for the head 16a of the fastening element or nail 16.
  • the channel 15 has lateral guide grooves 15a for guiding the edges of the holder strip 17 as his fed through the base plate la.
  • the channel 15 is shaped so that the holder strip 17 and its fastening elements 16 can be moved, in series, into position within the forward part 7b of the bore so that the fastening elements can be aligned with the piston and driven into the target material. While it is also possible to form the channel so that it has the full length'of the fastening elements for the entire length of its path through the base plate 1a, it is superfluous to provide the additional channel length after the fastening element has been driven, since it is only necessary to discharge the empty holder strip 17a from the outlet side 10 in the base plate 1a. If the portion of the holder strip 17a issuing from the outlet side 1c has a tendency, due to its length, to interfere with the operation of the setting device, it can be shortened or cut with a pliers, scissors or the like. 7
  • the holder strip 17 is perforated or punched out in positions spaced on the opposite sides of the hole in the strip which holds the fastening element.
  • the fastening element is displaced toward the forward or muzzle end of the device and that part of the holder strip between the punched out portions forms a washer on the shank portion of the fastening element and is guided, along with the fastening element head 160 through the forward part 7b of the bore.
  • a' recess 9c is provided which corresponds to the lug' or projection 16b formed on the head of the fastening element 16.
  • the recess 90 fits over the projection 16b on the fastening element so that during the driving process there is no lateral yielding of the fastening elements as they are driven forwardly through the forward part 7b of the barrel 7.
  • the holder strip is preferably formed of an aluminum alloy.
  • a device for driving fastening elements, such as nails, studs and the like, into a target material using an explosive force for propelling the fastening element from the device into the target material said device comprises a base plate located at the forward end of the device and arranged to rest against the target material into which the fastening element is driven, said base plate having an axially extending bore therethrough having a forward part defining the end of said. device from which the fastening element is driven and a rearward part located.
  • a piston axially displaceable through said bore from a first position located within the rearward part of saidbore to a second position located in the forward part of said bore, the device arranged to receive a fastening element strip holder for feeding fastening elements serially into position in said bore so that the elements can be driven by said piston as it is propelled from its first position to its second position, wherein the improvement comprises a channel in said have plate extending perpendicularly to and intersecting the axis of said bore, said channel arranged to receive and guide the fastening element holding strip through said bore for serially positioning the fastening elements in the path of said piston so that the elements can be driven into the target material, said channel having a first pair of guide grooves extending in a plane perpendicular to the axis of said bore for directing the edges of the fastening element holder strip through said channel, said first pair of guide grooves having a width greater than the diame-t ranged to guide
