Definitions

  • This invention relates to improvements in small-arms and machine guns of the kind in which the opening and closing of the breech for effecting the ejection and feeding of the -6 cartridges is automatically obtained by the discharge of the gases of combustion directly from the firing or cartridge chamber.
  • the object of this invention is to simplify this type of mechanism and to this end it consists broadly in causing the piston actuated by the discharge gases to act directly upon the'ejecting and feeding mechanism without the intervention of the intermediate delaying mechanism.
  • the piston is in the form of a rod attached at one end to the said mechanism, its other or free end extending into the open end of the cylinder in which it 5 freely moves.
  • the chamber closed by the piston can be varied in capacity by any convenient means, for the purpose of regulat-' ing the pressure to which the piston is subjected and the moment at which it is brought inder by the pressure of the gases generated on the ignition of the propellent charge.
  • the end of the piston may be bevelled so that the disc issuing from the cylinder strikes the bevelled surface and is deflected downwards.
  • the aforesaid slide actuates the breech bolt through the medium of a pin and camof lost motion is provided which gives a momentary delay before the breech is opened. Furthermore, to ensure that the piston shall re-enter the open end of the cylinder, on the closing of the breech under the action of the usual spring, the said cylinder'end is made bell-shaped orfiaring.
  • the slot maybe formed either in the slide or in the bolt, the pin being secured either to the bolt or to the slide.
  • Figure 1 is a sectional sideview of the breech portion of an automatic rifle pro vided with the improvements.
  • Figure 2 is a sectional plan thereof
  • Figure 3 is a section On the line 33, Figure 1.
  • Figures l and 5 are views at right angles of a detail and Figures 6 and 7 are also views at right angles of another detail.
  • Figure 8 is a sectional side view of a modified detail.
  • a is the breech of the rifle and b is the barrel secured thereto and containing the chamber 0 for the cartridge
  • Z. c is the breech-slide slidable in the body and f is the breech-bolt also slidable in the body and provided with the pin projection g engaging the cam-slot h in the breech-slide, so that the latter, when retracted, will effect the unlocking and retraction ofthe bolt f to withdraw the empty cartridge case from the chamber 0, and, when pushed forwards, will return the bolt to feed a fresh cartridge into the said chamber and to be again looked, all in the usual manner.
  • i is the piston to be actuated in one direction by the gases produced by the firing of the cartridges, the said piston being in the form of a rod extending into, and working in a cylinder j which is in communication with the chamber 0 by the orifice la.
  • the piston is directly connected to the breech-slide e by a spring-catch Z pivoted to the said slide and engaging a stud m on the piston carrier 0 The movement of the said piston by the gases efi'ects the unlocking and retraction of the bolt 7.
  • n is the spring for effecting the forward or return movement of the bolt f, through the medium of the rod 0 detachably connected to the piston i by the piston carrier 0 and working in the guide 0
  • the depression of the catch Z will disconnect it from the piston i and rod 0 to enable the slide 6 to be actuated by hand, if required.
  • the rod 0 and carrier 0 are connected together by a hooked stud 0 on the former passing through a slot 0* in the latter, the hooked portion of the said stud engaging one end of the said slot, as shown clearly in Figure 3.
  • the end of the rod 0 also engages behind lugs 0 on the back of the carrier 0 Inv order to disengage the carrier 0 from the rod 0 the latter must be moved in the direction'of the arrow, Figure 3, until the hook of the stud 0 is free of the said.
  • the cylinder j is joined to the barrel Z; by means of a coned seating j and locking rin 3' thereby ensuring ages-tight joint an enabling the said cylinder to be removed for cleaning the orifice 7:.
  • t is the straight extension of the cam slot 72.
  • a small-arm and. machine gun as claimed in claim 1 including means for varying the capacity of the cylinder containing the piston.
  • a small-arm or machine gun as claimed in claim 1 including a passage formed with an enlargement leading from saidcartridge chamber, through whiclrthe discs punched explosion gases.
