Definitions

  • This invention relates to fire-arms and consists essentially in providing a special construction of fire-arms in which the barrel is axially displaced with respect to the other parts of the fire-arm so that the rifleman may keep the fire-arm in its normal position permitting to conveniently take aim atan object, even in case the rifleman carries a gas-mask or a steel-helmet.
  • a further'feature of this invention consists in a novel construction of the piston-rod which forms part of the gas-pressure operated charging device for the purpose of preventing objectional strains from being imposed upon said piston-rod.
  • a further feature of this invention consists therein that the gas-cylinder of the gaspressure operated charging device is made integral with the carrier for the gun-sight to permit both of said parts of being easily exchanged by a single manipulation.
  • FIG. 1 is p a diagrammatic top-view'showing a fire-arm of ordinary construction
  • Fig. 2 a similar top-view of a fire-arm constructed according to this invention in contra-distinction to Fig. 1,
  • Fig. 3 a detail-view of the gas-piston together with the piston-rod
  • Fig. 4 a view, partially in section, of the carrier for the gun-sight and the gas-cylinder
  • Fig. 5 a sidevview of said carrier and the gas-cylinder
  • Fig. 6 a longitudinal central section
  • Fig- 7 a top-view, respectively of Fig. 5, Fig.
  • FIG. 8 adetail view showing the sight-carrier of Fig. 5 as seen from the right-hand side, Fig. .9 a section along line aa. of Fig. 5, Figs. 10 and '11 sections along lines 12-12 and 40 c--c, respectively, taken on Fig. 6, Fig. 12 a view and partial section of the connecting member which is arranged intermediate the sight-carrier and the gas-cylinder with a small protective tube serving for the protection of the upper partofjthe gunestock.
  • Figs. 1 and 2 thebarrel of the fire-arm is shown at 1, the central piece at 2 and the gun-stock at 8.
  • Fi 1 the three aforementioned parts of the %rearm are positioned in a common plane of symmetry s's,such as is ordinarily the case in known constructions of fire-arms.
  • .Ac cording to Fig. 2 the part of the fire-arm which consists of the gun-stock- 2 and the central piece 3 is inclined towards the bar rel 1 at an angle a which preferably amounts to about 1 as I have ascertained by experiments.
  • This axial displacement between the barrel and gun-stock and the central piece is so small that the lateral dimensions of the fire-armwill not essentially be increased and that in addition to this rifleman will not need to bring portions of its head above the buttend of the fire-arm during taking aim at an object. It will therefore be possible for the rifleman to properly take aim by merely slightly placing his cheek against the gunstock, even if the rifleman wears a gas-mask or a steel-helmet. The position in which the rifleman may hold the fire-arm will now be the normalposition and theaforementioned axial displacement of the several parts of the fire-arm will have no influence whatever upon its manipulation. r
  • the piston-rod is shown at 4, the 75 gas-piston at 5 and the handle or knob at 6.
  • the piston-rod for reasons of construction, had heretofore ordinarily been of somewhat bent conformation which during firing had resulted into bending strains upon the pistonrod.
  • the gas-pressure operated charging device now comprises a piston-rod composed of a central essentially straight portion a, b, 0, (Z extending along the greater part of the length of said rod, while the front part of said rod is of round cross-section in proximity to the piston as indicated at g, and of rectangular cross-secti'on inthe rear part.
  • Fig. 4 the piston-rod is again shown at 4;, the piston at 5 and the gas-cylinder'at 6,
  • the gas-cylinderE is made integralwith the sight-carrier which permits to conveniently exchange the gas-cylinder together with the sight-carrier in case of excessive wear of the barrel of the fire-arm.
  • the gas-cylinder 6 is connected by means of an extension 6 with the end'7 of the sight-carrier 7
  • the gas-cylinder is of alength which is smaller than the stroke of the gas-piston, this permitting convenient cooling of the gas-cylinder andrender ing soiling or sooting impossible so that a sticking of the piston to the cylinder will be eiiectively prevented.
  • the' sight-carrier 7 is providedat itsend with an extension 8 permitting the reception of the gun-sight proper within the dovetail-shaped (groove shown at the lefthandjendlof Figs. 5,, 6 and 7, the gun-sight itself being omitted in the drawing.
  • the bayonetecarnier isshown at 10.
  • An aperture I5 is provided in the wall which separates the gas-cylinder 6 and its extension '6 from the sight-carrier r7 and'7", said aperture permitting passage of the powder-gas from the barrel .into the gas-cylinder.
  • a bore 16 is provided inthe said extension 6 of the gaspressure cylinder 6 and a bolt maybe rotated in said bore in order to adjust a regulating device whichisnot shown in the drawing.
  • the frontside'o f the latter is provided withvan oblique 0. cal ur a a ind ated at 17.
  • gas-pressure cylinder 6 together with the extension 6 provided thereon is displaced with respect to the sight-carrier 7 by an than the the piston.
  • the piston-rod is loosely surrounded by a small tube 18 which serves for protecting the upper parts of the the action of the hot discharge gases.
  • said gas-cylinder may conveniently besubjected to treatment by heat, such as for instance to a hardening process, or some other process which serves for inlcreasingathe mechanical strength of said cylinder.
  • heat such as for instance to a hardening process, or some other process which serves for inlcreasingathe mechanical strength of said cylinder.
  • said central piece being positioned at an angle with respect to said barrel so as to perm'i-t the ,rifleman to take aim, even when wearing a gas-mask or a steel-helmet, by merely laying his cheek against the butt-end of the gun-stockwithout bringingportions of his head-above said butt-end.
  • a fire-arm as specified by claim 1 having agas-cylinder which-is adapted to form a restfor the butt-end of the fire-arm and connected with a sight carrier means of an extension provided on said gas-cylinder.
  • a firearm a Specified Claim in which the gas-cylinder is adapted to-form .a rest for the butt-end otthe fire-arm and provided with anextension,'saidgas-cylinderbein'g connected with 't'he end of rier by means of said "extension.
  • a fire-arm as specified by claim 1 comprising a gas-cylinder, an extension thereon, a piston, a piston rod having a Varying cross-section and including a central member extending over the greater part of the length of said piston rod and a tube-shaped sight carrier integral With said gas-cylinder, said gas-cylinder together With said extension being angularly displaced with respect to the axis of the tube of the sight-carrier and to the longitudinal axis of the barrel.
