Definitions

  • the invention relates to stud-driving apparatus for the insertion of anchoring studs in hard materials such as stone, concrete, iron and the like. More in particular, this invention relates to such apparatus in which an expanding propellant charge exerts a force on the anchoring studs, which may be in the form of nails, bolts, etc., and may be without heads or may have heads including threaded heads.
  • a propellant charge is used to drive an anchoring stud in such a manner that the stud is accelerated during the course of its free iiight to the point at which it is driven in.
  • the propellant charge works directly on the anchoring stud or through a driving piston which acts as a hammer for the stud.
  • the expansion of the propellant charge exerts an impact effect; that is, the charge drives a body, separated by a given distance from the anchoring stud, against the anchoring stud in such a manner that the anchoring stud is not accelerated in any free ilight.
  • the cartridge containing the propellant charge has a iixed position in the apparatus, and the recoil from the propellant charge acts either directly against the stud-driving apparatus or indirectly thereon through springs or braking mechanisms.
  • the present invention is concerned with a design for such devices in which the expansion of a propellant charge brings about the driving in of an anchoring stud without acceleration of the stud during the course of free flight.
  • One object of the invention is the complete or virtual elimination of recoil in the apparatus.
  • a further object of the invention is the accomplishment of the insertion of anchoring studs with the smallest possible propellant charge with consequent advantages from the viewpoint of safety, one of these advantages being that the energy unexpended at the conclusion of the driving thrust is conveniently absorbed. In this manner penetration of the hard material is eifected practically without rebounds and recoiling.
  • Additional features of the invention are concerned with control means by which the energy released during accidental firings is harmlessly absorbed, as well as with control means which eliminate such accidental rings.
  • the stud-driving apparatus to be described hereinbelow is principally characterized in having the propellant charge fitted between a recoil damping piston on one side and the anchoring stud or hammer means carrying the anchoring stud on the other side. Additionally, the position of this charge along the longitudinal axis of the apparatus is adjustable.
  • the recoil damping piston can be provided with a friction element which holds the piston in any desired position within the guide tube.
  • the front face of the recoil damping piston is designed as a receptacle for the cartridge holding the propellant charge.
  • the axial position of the cartridge at the moment of firing is automatically determined by the length of the anchoring stud to be driven in, or by the anchoring stud and a hammer for the stud.

  • FIGURES 23 land 24 are side views partly in section of another embodiment [for preventing accidental firing, in which figures Itwo different positions of the recoil damping piston are shown.
  • the stud-driving apparatus shown in FIGURES 1 through 3 is comprised principally of a tubular guide 1 having a piston Z provided with enlarged lleading end 3 and free to move in the guide 1.
  • the opposite end fiof the piston extends into closing member 5 which is provided with a friction element 6 so that the piston remains in Iany desired position. Extension of the piston out of the apparatus is prevented by the engagement between the shoulder of the piston leading end '3 and surface 40 of closing member 5.
  • On the end of the piston which projects outwards from the apparatus is fastened a mass in the lform of an iron head or cap 7, which is replaceable by other similar caps.
  • Closing member S can be slid down along the neck 8 of tubular guide 1 and can he fastened to the guide by a 90 degree turn tot bayonet-like wedge breech lock 9. Closing member 5 may be locked in closed position by means of ball catch lit.
  • a hammer 13 is mounted in tubular guide 1 in slidabie fashion in -front ⁇ oi the leading end of piston 2.
  • a recess for holding and centering the back end of an 'anchoring stud l5 on which perforated disc 19 is placed.
  • Disc 19 centers stud n1S in driving aperture 20 before Land during the driving process.
  • Hammer 13 is provided iwith iiriction elements for example spreading rings 52.
  • the rear face of hammer 13 is provided with a broad, level, iiring pin 13, the surface area ⁇ of which covers between one-fifth and the entire base area of the cartridge, preferably about one-half this area. This avoids a sudden ignition which is undesirable in this type of device.
  • the expansion volume throughout which the propellant charge is effective ladjusts itself automatically according to the length of the stud being driven, or 'to the form and size of hammer 113 driving the st-ud.
  • Large hammers of heavy mass are chosen to drive even small studs of minimal mass if good penetration of a very hard material is desired.
  • short studs are used in hard materials, long studs in soft materials. rl ⁇ he device of the invention accommodates itself readily to such variations.
  • hammer 13 When in its lowest position ⁇ during a stud-driving stroke, or when nearly in such position, hammer 13 exposes exhaust apertures 22 in the walls of tubular guide 1, through which the expanding propellant passes into closed space 23 surrounding tube 1 as a jacket. Because of the expansion of the gases into a closed volume, practically all explosion noises are avoided.
  • Space 23 is closed on the exterior by' ⁇ shell 24, which also serves as a hand grip for the device.
  • Shell 24 can be drawn upwards over tube 1, after removal of closing member 5 and locking pin 25, to clean space 23 of remaining explosion gases. Such cleaning is required only after a large number of explosions, however.
  • Firing can be initiated by a light hammer ltap against cap 7 of the piston 2. Generally the piston is thereby shoved -forward into the tiring position, though not necessarily so. lf the hammer remain-s in position on cap 7 after the blow, an increase in mass opposing the reactive force of the propellant results.
  • lche closing member 5 serves as a stop means for limiting the forward movement of the piston'Z.
  • closing member 5 After release of closing member 5', it and piston 2 can be removed from the device and replaced with an ordinary plunger 26 (FIGURE 4) driven by hammer blows.
  • Closing member 5 can be replaced on neck 8 with protective plate 27, which plate can be fastened in place as was member 5. It can also -be seen in FIGURE 4 that the lower end of plunger 26 has a recess 28. Such a provision avoids vdamage to tiring pin 1S on hammer 13 which might otherwise be caused.
  • the device also has a broad positioning base at the lower end of shell 24, and this base in the embodiment shown is constructed in two parts with base plate 2?, positionable against the surface of the hard material, removably attached by means of screws 30.
  • Permanent magnets 31 (see also FIGURE 2) are mounted in two diametrically opposed radial cavities in base plate 29. The magnets hold stud 15 and perforated disc 19 in position before and during the driving process.
  • mechanical means can also be provided for holding disc 1g, such as springs extending in the axial direction and projecting slightly over the inner wall of driving aperture 2t).
  • the positioning base is flattened along one edge 41.
  • the device can be used in any position, so that, for example, aperture 20 may face down, or up as against a ceiling, or sideways against a wall.
  • initiation of tiring can take place other than by a hammer blow on the cap of the piston.
  • a posterior tubular extension 32 has mounted in it hammer-like masses 34 and 35, compressible against spring 33.
  • This structure cooperates with trigger mechanism 37, mounted in handle 36, so that after triggering, masses 34 and 35 strike head 38 of piston 2a and thereby eiect tiring.
  • the reaction forces, in this case, are taken up by masses 34 and 3S, and head 33.
  • the device in FIGURE 6 is constructed like that in FIGURE 1.
  • FIGURE 9 taken through cartridge recess 11, shows that the walls of this recess deviate slightly from a circular configuration. This has the advantage of accommodating a force lit for the cartridge 12. A force fit can also be obtained by a slight expansion in the cylindrical walls of the cartridge, as shown by the broken lines in FIGURE 10.
  • FIGURE 7 shows that a cartridge 12 containing propellant may in some instances be mounted in a recess 39 in the end of hammer 13a that is opposite to leading end 14a.

  • the stud be driven in with its leading and trailing ends axially aligned as precisely as possible. It is also important that the driving force exerted on the stud acts centrally and axially on the trailing end of the stud. To achieve these ends, the forward end of the stud is suitably centered and axially aligned by means of a perforated disc 19 on the stud shaft. In place of discs, the studs can be anteriorly guided by jaws 4S, as shown in FIGURE 8. The jaws can be moved sideways and are complementarily recessed to form a guiding aperture to receive the stud.

  • FIGURES 13-16 are equipped with a safety mechanism by means of which a stud shot from the guide tube of the stud-driving apparatus is intercepted, except when the apparatus is in position with its base placed against a surface.
  • a hinged bent arm 53 is mounted, in the axial plane of guide tube 1a, on base plate 2911. Arm 53 is moved automatically by spring 54 into the safety position shown in FIGURE 13 and held in this position by the spring. As shown in FIGURE 14, when base plate 29b is placed against the surface of material 21, arm 53 is swung into a position leaving a free path for the driving of a stud. In the safety position shown in FIGURE 13 stud 15 with its associated perforated disc 19 is intercepted in funnel-shaped opening 55 in arm 53. Opening 55 is coaxial with guide tube 1a.
