Definitions

  • the barrel is axially displaceable in a chamber and subjected to the action of a propulsion spring.
  • the impact guns must be firmly pressed onto the materials into which the pin is propelled whereupon the gun barrel is pushed back and the cartridge inserted into the rear end of the gun is fired.
  • This object is realized in conformity with the invention by the provision of a pressure releasing chamber surrounding the front portion of the gun barrel and acting as a recoil buffer.
  • This pressure releasing chamber is p-re-ferably formed by a sleeve applied to and surrounding the front end of the gun barrel with a certain distance therebetween to create said chamber; the sleeve is provided with a front flange cooperating with gas exit channels the latter being so located in said front flange that in the advanced position of the barrel the front portion of the sleeve is located in the rear and in its rearward position is located in front of the gas exits from said channels.
  • Fig. 1 is a longitudinal vertical section of the front portion of the gun
  • Fig. 2 is a similar sectional view showing the casing and sleeve in their advanced position relative to the muzzle of the barrel.
  • the gun forming the subject matter of this invention essentially comprises a cylindrical casing 1 axially displaceable with respect to a barrel 3, a recoil spring 2 being arranged between the casing 1 and the barrel 3.
  • the barrel 3 has a rear portion surrounded by the spring 2, a middle portion and a front portion being in the position shown in Fig. 1 outside the sleeve 5 moved to the front portion of the casing 1.
  • the device is provided with a customary equipment, not shown, to actuate the gun; a hole 4 serves to receive the means connecting the gun with its operating parts, as described in the above referred-to prior copending patent applications.
  • a sleeve 5 is screwed onto the front part of the casing 1; this sleeve 5 surrounds the front portion of barrel 3 and is provided with a frontal flange 6 supported upon the front portion 3 of the barrel.
  • Inwardly inclined gas channels 7 are provided in this front port-ion 3 gas exit openings 8 leading from the channels 7 are connected with each other by a recess 9 applied to the periphery of said barrel 3.
  • the channels 7 and the recess 9 are so positioned that flange 6 is in the advance position of the barrel 3, see Fig. 1, located in the rear of the recess 9 and of the gas exits 8; in the rearward position of the barrel 3 shown in Fig. 2 the flange 6 is located in front of said recess 9 and said gas exits 8.
  • a buffer spring 12 is located between an inner abutment 10 pro-- vided in barrel 3 and an inner abutment 1 1 provided in sleeve 5.
  • a cartridge container 13 is located at the rear end of easing 1 and of sleeve -5 connected therewith.
  • the barrel 3 has under normal conditions the position shown in Fig. 1, whereby the barrel end 14 projects with its annular recess 9 beyond the sleeve 5.
  • the device In order to shoot the bolt into the solid material aggregate, for instance a wall, the device is set with its end 14 upon the objective and the casing 1 and sleeve 5 are moved to their forward position (Fig. 2) against the action of the recoil spring 2, whereby the fuse cap (not shown) of a cartridge being present in the container or chamber 13 enters into the reactive sphere of a firing bolt.
  • driving gases enclosed in release chamber 1 6 may escape through channel 7 and boreIS.
  • a device for shooting pins and bolts into solid material aggregates comprising, in combination, an outer casing, a barrel having a rear portion, a middle portion and a front portion, said casing being axially displaceable with respect to said barrel, an abutment forming part of said barrel, a recoil spring located between said abutment of said barrel and the end wall of said casing so as to hold in the expanded position of said recoil spring said barrel and said casing in a relative position wherein said middle and front portions of said barrel protrude beyond said casing, a sleeve connected to the front portion of said casing and surrounding said middle portion of said barrel, said sleeve forming a gas release chamber surrounding said middle portion of said barrel so as to act as a recoil buffer, and a flange forming the front end of said sleeve, said barrel having a longitudinal bore connected with gas exit openings arranged between said front and middle portions of said barrel, said flange cooperating
  • a device as claimed in claim 1 and an angular recess provided in said barrel and separating said front portion from said middle portion, said angular recess being located outside said sleeve and said frontal flange, when said recoil spring is in expanded condition, said angular recess being inside said sleeve when said recoil spring is in compressed condition.
  • a device as claimed in claim 1 said sleeve having an abutment surrounding said middle portion of said barrel, an abutment on a rear portion of said barrel engaging said recoil spring, and a buffer spring surrounding said middle portion of said barrel and abutting against said abutments of said sleeve and said barrel.
