  • FIG. 12 is a sectional view of one gimp nail, drivenoff the stock material of FIG. 10 and drive in a wooden structural element, for example.
  • FIG. 1 illustrates an apparatus generally comparable with a conventional well known pneumatically operated stapler, designed to be connected to a source of pressurized air (not shown) by means of a suitable hose, the outlet end portion of which is fragmentarily indicated by dot-and-dash lines.
  • Such apparatus comprises a substantially cylindrical body 10 wherein a known driving tool actuated by cylinder-piston means is located.
  • body 10 is fixedly secured to or integrally formed with a hand-grip forming extension 12.
  • suitable trigger means are located for actuation of the apparatus.
  • Such trigger means preferably consists of a trigger lever 14 pivoted at 16 to the hand grip.
  • an outlet piece 18 is located, such outlet being bored for axial driving of individual gimp nails each having a relatively short pointed stem 26 and a relatively large essentially hemispherical head 28, the details of such gimp nails being shown in larger scale in FIGS. 10 and 12.
  • a cylinder 20 (fragmentarily shown in FIG.'2) is located within the body 10 .
  • This cylinder forms a part of a well known pneumatically operated driving tool actuator, which will not be described and shown as appertaining to current art.
  • a pushbutton 22 connected to an also well known valve device (not shown) is depressed by which the actuator is caused to promote the stroke of the driving tool to drive a nail in direction.
  • Said trigger lever 14 comprises a cross-part 24 positioned engage the valve operating push-button. 22 from below.
  • a known device such as a pneumatically operated stapler or nail driver
  • a known device such as a pneumatically operated stapler or nail driver
  • the operator gripping the device at its extension 12, positions and applies the outlet piece 18 to the surface S into which one gimp nail is to be driven.
  • a gimp nail '26 By acting on the trigger lever 14, a gimp nail '26, is forcedly expelled through said outlet piece and driven-in.
  • One feature of the invention consists in the improved magazine portion of the device.
  • Such portion includes a guide passage 30 (FIGS. 2, 8 and 9) longitudinally joining another extension 32 of the body 10.
  • Such guide passage is longitudinally grooved for guiding the stems 26 of the gimp nails, in aligned and parallel relationship while the large heads thereof slide over planar surfaces at both side of the groove.
  • Another important feature of the invention consists in the fact that the gimp nails 26, 28 are fed into the magazine portion in form of a stock material wherein a plurality of gimp nails are secured to each other, in aligned, parallel and evenly spaced relationship (the interval between the stems 26 of adjacent nails being equal to or very slightly greater than the diameter of their heads 28), by a strip or tape 34 of essentially flexible material which can be readily severed or torn-off between subsequent nails.
  • Such tape 34 preferably made of plastic material, such as polyvinyl chloride, is few tenth of a millimeter thick and wide less than the diameter of heads 28.
  • the tape 34 has evenly spaced perforations 122 preferably beaded at 124, wherein the several stems 26 are individually fitted until the heads 28 abut on the upper face of the tape.
  • This tape is further provided with evenly spaced and symmetrical indentations 126, where the heads 28 are adjacent (see in particular FIG. 11), to facilitate the severing or rupture of the tape during driving of individual nails.
  • a piece 34a of the tape 34 will remain below the head 28 of the driven-in nail. This fact does not prejudice the drive-in and the firm grip of the nail in the structure 118, and it is also advantageous.
  • the piece 34a will remain fully concealed below the nail head 28 and protects the inside of same from moisture penetration, for example, thus preventing rusting or oxidization of the welded connection at 112 of the stem 26 to the head 28, staining of the covering material 116, as sometimes occurs when conventionally manually driven-in gimp nails are used.
  • the said stock material consisting of the plurality of gimp nails 26, 28 and the tape 34 might evidentally be very long, when including a relevant number of gimp nails spaced according to the diameter of their heads 28.
  • Such stock material can be slidably set within a proper magazine consisting preferably of a hose 36 (fragmentarily shown in dot-and-dash lines in FIG. 1) connected to the inlet end portion of magazine portion 32, as above indicated.
  • hose 34 can be wound about a large diameter drum, or otherwise sustained and arranged, or the stock material can be suitably coiled into a suitable container having an outlet arranged for having the stock material transferred into the magazine portion of the device.
  • Such cylindrical passage is of diameter slightly greater than that of the heads 28 of the gimp nails.
  • the pneumatically operated piston has a cylindrical driver too] 40 secured thereto for reciprocation in said bore 38.
  • the lower end portion 42 of the driver tool is concave and preferably tubular for abutment from above on the head 28 of the gimp nail positioned in said bore, for driving the nail in direction B, through the outlet piece 18 and then driving it in where desired, upon actuation of the known pneumatic mechanism, triggered by a pressure exerted on said push-button 22.
  • the trigger lever 14 acts on said push-button 22, by means of its part 24, and on a second lever 44 oscillatably pivoted at 46 to the body 10 of the device.
  • said second lever 44 is pivoted at 48 to a small pawl lever 50 adapted to engage individual heads 28 of the aligned nails and to step-by-step successively positioning the foremost nail in the bore 38.
  • An extension 52 of the pawl 50 is provided for disengaging such pawl from the nails, when the operator desires pulling back such nails from the magazine portion of the device.
  • other ratchet pawl means 54 are provided for preventing unduly back motions of the forwardly progressed nails. Such ratchet pawl means can be raised for disengaging the nails upon acting on same extension 52.
  • the ratchet pawl 54 is pivoted at 56 to the structure 32 of the magazine por tion and it is spring biased by a small spring 58.
  • connection between the trigger lever 14 and the second lever 44 is provide by a pin 60 secured to the end portion of lever 14 (opposite to its end pivoted at l6, FIG. 1) and slidably engaged in a groove 62 in the second lever 44.
  • Such groove has two differently inclined parts along which the said pin 60 successively runs during the motion of the trigger lever in direction A.
  • the outlet piece 18 is preferably provided with means adapted to improve the driving and to correct misalignment, if any, during the driving stroke.
  • Such means are made, for example, as shown in FIGS. 3 an 4.
  • Two (or possibly more) wing pieces 70 are symmetrically and oscillatably located at the sides of the outlet piece 18, and biased towards each other by rela tively weak springs 72.
  • the lower portions of said wing pieces are converging towards each other and jointly form a nearly conical guide, pointing downwardly and having its downward pointing apex in the axis of bore 38 and driver tool 40, 42. Therefore, as the driver tool starts it downward driving stroke, a sequence of steps nearly instantaneously occurs:
  • the driver tool end 42 abuts on the nail head in the bore 38, and starts drive same to downwardly, the edge of the head 28 severs or tears the tape 34, the part 34a (FIG. 12) below said head being carried with the nail;
  • the inwardly converging lower portions of the wings are contacted first by the lower pointed end of the stem 26. If such stem was not exactly coaxial with the bore 38, such pointed end will be deviated in the axis of the bore by sliding on the inner face of the contacted wing;
  • the head 28 will at its turn engage the wings 70, causing the same to diverge (overcoming the springs 72) for passage and driving out of the head of the nail.
  • the pointed end of the stem 26 will protrude from the outlet piece 18 before the head 28 will start to diverge the said wing pieces, and therefore such end of the stem will have engaged the material into which it is being driven. Such engagement will ensure the proper position of the stem and the correct.
  • FIG. 7 illustrates an ancillary implement which further improves the correct positioning of any gimp nail in the bore 38, preparatory to driving-in.
  • Such implement has also swingable wing pieces 74 biased by small springs 76 and symmetrically located in the outlet portion 78 of the grooved guide passage 30 in the magazine portion 32 of the device.
  • Such wing pieces 74 form a tapered passage therebetween, in which the stems of the gimp nails are caused to improve their co-planarity with the axis of the bore 38 while being pushed thereinto by the pawl 50.
  • a device for sequentially driving gimp nails, connected in a row by a tape and having each a relatively large head and a coaxial pointed stem, into a workpiece comprising, in combination, reciprocable driver means including a driver rod movable along an active stroke for engaging the head of a nail and driving the latter into a workpiece, and a return stroke; guide means including a cylindrical passage for guiding said rod and the nail driven thereby, passage means communicating at one end with said cylindrical passage for guiding the tape connected nails toward said cylindrical passage; actuating means for actuating said reciprocatable driver means and including a trigger lever pivotally mounted at one end so as to be tiltable from a rest position to an actuating position causing said driver rod to move along its active stroke; and
  • slot portions including an angle with each other, and a pin fixed to the other end of said trigger I lever slidingly engaging said slot, said slot portions being arranged in such a manner so that during movement of said pin in one of said slot portions, said pawl is moved towards said cylindrical passage to place the leading nail into the path of said driver rod, and so that movement of said pin in the other slot portion causes partial return movement of said pawl before said trigger lever reachesits active position.
  • said cylindrical passage is formed with a pair of opposite openings, including a pair of pivotally mounted wings respectively extending through said openings, and having slanted faces converging toward the axis of the cylindrical passage and spring means engaging said wings for urging said slanted faces towards each other for guiding thepointed end of a nail along said axis during driving of said nail by said driver rod.
  • said passage means for guiding said tape connected nails toward said cylindrical passage comrises a central groove for the passage of the stems of said nails therethrough, and a pair of coplanar faces to opposite sides of said groove for guiding the tape.
  • a device as defined in claim 1 including a hose magazine connected to the other end of said passage means.
