Definitions

  • This invention concerns apparatus for operating machine guns of the kind in which the working mechanismof the gun itself comprises a recoiling breech block which is initially displaced to supply the energy required to load and/or re the first shot and in which the energy required to discharge a series of rounds subsequent thereto is derived from the energy of recoil consequent upon the initial and each of the successive discharges.
  • the invention is designed to operate machine guns of the kind in which the recoiling breech block is displaced from an initial position to an intermediate safety position from which it returns to the initial position thereby rendering the gun ready to be fired.
  • each gun may be placed in the most favorable position, and so that one or more rounds may be fixed thereby without necessitating the immediate proximity of the gunner.
  • Such remote fire control is 'particularly advantageous in aircraft as it enables several guns to be located far apart on the Wings and/or in other positions and enables such guns to be fired without regard to the airscrew, by one person alone.
  • pneumatic operating means comprising a compressed air supply connected to a trigger motor comprising a cylinder and piston, which piston is displaceable into contact with the said trigger or button by the operation of a valve interposed between the said motor and the said air supply.
  • Fig. 1 is a diagrammatic representation of the general arrangement of the pneumatic operating means including the pipe circuits;
  • Fig. 2 is a part sectional side elevation of the chief flying control, and valve mechanism operated therefrom;
  • Fig. 3 is a side elevation of the pneumatic safety cooking mechanism;
  • Fig. 4 is a part sectional plan view of the cooking mechanism shown in tion of the spring loaded gun trigger actuating piston and cylinder.
  • Fig. 6 is a view similar to that of Fig. 3 of a different embodiment of certain parts of the invention.
  • Fig. 3; and Fig. 5 is a part sectional side eleva- In the general arrangement shown diagrammatically in Fig. 1 compressed air is carried in a container I from which the air supply is released to two pipesI 2 and 3.
  • the pipe 2 transmits air under pressure to l the valve casing 4 carried-by the chief flying control and when this valve is opened the air passes on through the pipe 5 to the cylinder of the trigger motor 6, the piston l of which is eX- pelled to press upon the firing trigger or button lo 8 of the gun 9.
  • the valve in the casing 4 is opened and shut by the movement of a firing control in the form of a lever I0 carried by the chief flying control I I.
  • Depression of the push button I3 admits air under pressure to the pipe I5 by which it is transmitted to the loading cylinder I6, the piston rod II of which is expelled thereby into contact with a member I8 forming part of and projecting from 25 the internal recoiling loading mechanism of the gun 9.
  • the other push button I2 when depressed admits air under pressure from the pipe 3 connected to the container I to a pipe I9 connected 0 to a cylinder 20, the piston 2
  • the internal loading and recoil mechanism of 35 the gun which is not shown is operated by the forward and backward movement of an internal recoiling breech having an actuating member II! ⁇ projecting from the casing 9 enclosing the gun.
  • the recoiling breech member I8 is carried to a position shown in full lines in which the toe of the catch 22 on the lower portion of the forward end of the detent momentarily overrides a trip catch 38 which is maintained in .the position shown by a spring 3I.
  • a iiring block 2I' may be positioned, as shown in Fig. 6 and may be provided xed in the position occupied by the piston 2
  • the firing button or trigger of. the gun itself is shown diagrammatically at 8 in the form of a button projecting from an aperture in the gun housing 9, Fig. l. f
  • the trigger or iiring button of the gun is actuated by a firing control which in the construc tion 'shown takes the form of a finger lever I0 which in the case of a gun on an aircraft may be mounted on the control ring handle II of the chief flying control so that the gun is aimed and fired at the target by directing the aircraft itself in the direction of the target.
  • a firing control which in the construc tion 'shown takes the form of a finger lever I0 which in the case of a gun on an aircraft may be mounted on the control ring handle II of the chief flying control so that the gun is aimed and fired at the target by directing the aircraft itself in the direction of the target.
  • two or more such firing levers may be positioned. side by side upon the chief flying control to permit of firing several guns or groups of guns at the same time.
  • Fig. 2 pivoted to the base of the spade grip at 31' and having a forwardly directed toe portion 38 which on movement of the lever'from the dotted line position to the operating position shown in full lines pushes down a connection 38, the base 48 of which depresses a cylinder 4I loaded by a spring 42 upon an apertured washer 43 of yielding material such as rubber.
  • the compression of. the-washer 43 seals an air chamber beneath it and permits the base of the cylinder 4I to contact and downwardly to displace the valve spindle 44 which carries with it the seating portion 46 thereby separating the said seating portion from its fixed coacting tubular conical portion 46.
  • Air under pressure is thereby admitted from the container I into the chamber, the upper end of which is temporarily sealed by compression of the washer 43 and passes through slots 36 and annular ports 41 into the outlet pipe 5.
  • the piston 28 and its rod 29 move outwardly of the cylinder and the portion of the detent 26 engages the recoiling breech member I8 and carries it to the outer limit of its stroke.
  • recoil member I8 may either be detained or immediately released as described previously.
  • the gun having been loaded by the above operations depression of the firing lever I res the gun by unseating the valve disc 45 to admit air from the container I to the cylinder 5, the piston of which depresses the gun firing button or trigger 8.
  • valve I3 is opened admitting air through the pipe I5 to the right hand end of the cylinder I6. This forces the piston 28 to thc left carrying with it the piston rod I'I and detent 25. The detent 25 engages and moves the depending arm I8 of the breech block. When the piston 28 reaches the end of its stroke the catch 22 engages the latch 30 and is held in its extended position.
  • valve I2 Upon opening the valve I2, air flows from the reservoir through the pipes I8 and I9 to the cylinder 2Q, pushing the piston 2I outwardly against the upwardly projecting nger 32 of the catch, first swinging the part 25 to release the breech block arm I8 so that it may return to its original position shown in dotted line in Fig. 3, and then releasing the catch 22 from the latch 30.
  • the springs 33 then draw the piston rod I'l of the catch mechanism back to its original position.
  • the upwardly projecting finger is stopped by the stops 34 throwing the catch 25 upwardly in position to again engage the arm I8.
  • the gun is now cocked and ready to re.
  • the valveA To re the gun, the valveA is opened admitting compressed air from the reservoir I through the pipe 5 tothe cylinder 6.
  • the air admitted to the cylinder 5 forces outwardly the piston 48 and projecting parts I to actuate the trigger 8 and re the gun.
  • Pneumatic cocking means for rapid firing small arms having a recoiling breech block and gun ring trigger, which comprises a pneumatic cylinder and piston, a valve to control the admission of air to said cylinder, a detent movable with said piston and a member extending from said breech block and engaged by said detent during the outward stroke of the piston, said detent being displaceable to release said mem-A ber, a catch mounted on said detent and a springv actuated latch engaged by said catch to hold said catch and said recoil member at the end of the outward stroke of the piston.
