Definitions

  • the present invention is intended to overcome this deficiency and has for its object the new article of manufacture which consists of a particularly effective and inexpensive guide means for a sealing element having a front stem and a rear head, the rear extremity of which is already provided with a guiding arrangement or device, the said new guide means being characterized in that it consists of a cap which is fitted at least to a partial extent over the front portion of the rear head of the sealing element and the periphery of which has at least three points inscribed Within a circumference which is substantially co-axial with the sealing element and which substantially corresponding to the bore of the gun barrel.
  • the arrangement is preferably such that the thickness of the wall of that portion of the guide means which is fitted over the front of the head is so designed that the said portion substantially fills the annular space between the said head and the internal wall of the gun barrel.
  • this latter consists of a small polygonal plate pierced with a hole having a diameter which permits the said plate to be force-fitted over the stem of the sealing element and to be brought into abutment with the head of the said element, the said small polygonal plate being designed so that each summit at least of the polygon can be bent back against the said head and thus be inscribed within the circumference which substantially corresponds to the bore of the gun barrel.
  • this latter is further characterized by the following features and combinations thereof:
  • the small plate has the shape of a regular polygon which has concave sides so as to form relatively projecting summits, thereby giving the said plate the appearance of a star having short points which alone are intended to be bent back;
  • the small plate has a thickness such that those portions thereof which are bent back against the head of the pin fill up radially the space between the pin head and the gun bore;
  • the bent-back portions of the small plate have a certain elasticity
  • the small plate is made of a material which is readily destructible at the time of impact of the said plate against the material which is intended to receive the sealing element;
  • the small plate is made of aluminum sheet or brass sheet.
  • this latter consists of a substantially frusto-conical cap which is advantageously of plastic or of like material, the said cap being fitted over the rear part of the stem of the sealing element and advantageously terminating in arms which fit over the front portion of the head of the said element.
  • screw-threads are formed on the internal surfaces of the arms and are intended to come into engagement with the screw-threads of the said head.
  • FIG. 1 is a front view of a first form of embodiment of the guide means
  • FIG. 2 is a sectional view showing the small plate of FIG. 1 which is crimped onto a pin placed inside the barrel of a sealing gun;
  • FIG. 3 is a view looking on the end of FIG. 2;
  • FIG. 4 is a view taken in perspective of an alternative form of embodiment in which the guide means is a cap of plastic;
  • FIG. 5 is a view in longitudinal cross-section of the guide means of FIG. 4 which is fitted on a sealing pin;
  • the guide plate 1 of brass or aluminum is of square shape and the sides 2 thereof are slightly concave so that the summits or corners 3 have the appearance of the points of a star.
  • the hole 4, which is located at the centre of the plate 1, has a diameter such that there can be force-fitted therein the front portion 5a of a pin 5 having a rear head 5b.
  • sealing and centering plug 6 of plastic for example, which is fitted over the rear of the pin head, the said head being assumed to be threaded.
  • the portion 5a of the pin is fitted inside the hole 4 of the plate 1 until this latter comes into abutment with the pin head 5b, the corners 3 of the said plate being bent back by crimping, for example, so as to be pressed against the said pin head until the maximum cross-section of the combined assembly of pin and plate substantially corresponds, as shown in FIGS. 2 and 3, to the bore of the barrel C of the sealing gun.
  • the guide means consists of a cap 7 of substantially frusto-conical shape and preferably of plastic, the said cap comprising four arms 8, on the internal faces of which are formed threads 9 which, as can be seen in FIG. 5, are intended to be brought into engagement with the threaded portion of the head 5b of the pin 5, on the stem 5a of which is fitted the cap 7.
  • the new guide means for the sealing elements such as pins, nails, etc. has proved to be particularly etfective and the sealing devices which are fitted with the said guide means accordingly become new articles of manufacture.
  • the guide plate of FIGS. 1 to 3 could be either triangular, pentagonal, hexagonal, etc. or even circular.
  • the said plate could have the appearance of a cup which is fitted over the head of the pin.
  • the cap of FIGS. 4 and 5 could have a number of arms 8 other than four.
  • a fastener intended to be fired with an explosively actuated power tool comprising: a stem having a pointed front end; a rear head forming one piece with 20 said stem and having a greater diameter than that of said stem; and guiding means consisting of a substantially frusto-conical cap made of destructible material and having a central opening wherein is forcibly engaged the stem and whose periphery has arms fitted over the front part of said head, wherein the head is threaded, whereas the internal surfaces of the arms in contact with the head have a thread which is in engagement with the thread of the head, the periphery of said cap having at least three points which are inscribed within a circumference substantially coaxial with the fastener and whose diameter substantially corresponds to the calibre of the power tool.
