Definitions

  • a gas operated gun with a barrel defining a rearward extension including a widened portion accommodating a bolt and a valve.
  • the bolt is spring urged to open the valve at the end of the extension which in turn allows compressed gas to return the bolt to a forward position.
  • a gas passage extending through the bolt is opened and allows the gas to expel a pellet from the barrel.
  • a magazine for the gun is an elongated container accommodating a stack of pellets, and has a resilient tongue for inserting into the housing enclosing the barrel; the tongue normally holds the topmost pellet in the magazine; but when inserted in the housing, the tongue is cammed outwardly to release the topmost pellet.
  • This invention relates, in general, to the construction of guns and a magazine therefor, and in particular, to a new and useful fluid pressure operated gun which includes a bolt which is slidable in the barrel of the gun and which defines a fluid pressure gas passage which communicates at the rear portion of the barrel with a fluid under pressure which provides the propelling force for the gun projectile; and also to an improved magazine construction for such guns.
  • the present invention is particularly directed to the construction of a gun such as a rifle or a piston which may be operated by a fluid pressure force which may be obtained for example, from a container of a pressurized mechanism such as a carbon dioxide container.
  • the construction is an improvement over the prior art, particularly in respect to the simple and easy means for conveying pellets or projectile elements to the bore of the gun in front of a movable bolt having a gas passage which is communicated during each reciprocating cycle with a supply of gas under pressure to projectile the pellet out of the gun barrel and to recock the gun.
  • the construction is such that the bolt may be easily cocked initially by engagement of a bolt handle secured thereto. The bolt sliding operation after the trigger is released will be effective to communicate the desired gas pressure to the bore of the barrel for firing the pellet during each subsequent release of the trigger.
  • the pressurized medium is employed to displace the bolt back into a cocked position and to thereafter provide the, fluid gas for propelling the projectile out of the barrel.
  • This is accomplished by constructing the bolt so that its end face will be exposed to the pressurized medium initially and will be caused to advance in a direction parallel to the bore of the gun barrel up to a point at which it engages within a trigger latch mechanism and it compresses a bolt spring.
  • the bolt spring provides the actuating force for initiating the backward movement of the bolt to open a valve for communicating the rear chamber with the pressurized medium.
  • the magazine which is engaged in a transverse channel which communicates with the barrel bore at a location ahead of the bolt when it is in a retracted position in- 3,572,310 Patented Mar. 23, 1971 cludes spring means for automatically feeding the next projectile upwardly into the bore ahead of the sleeve.
  • the arrangement provides a simple and inexpensive automatic mechanismfor the automatic firing of a plurality of pellets or similar projectiles.
  • an object of the invention to provide an improved gun construction having a slidable hollow bolt which communicates during its slidable movement with a source of fluid under pressure and which is moved by this fluid pressure in an advancing direction to again cock the firing mechanism and to provide a propelling gas for propelling the projectile out of the barrel core.
  • a further object of the invention is to provide a gun construction providing a simple means for feeding pellets into a barrel and for firing the pellets from the barrel and for automatically recocking the device during each firing cycle.
  • a further object of the invention is to provide a gun construction which is simple in design, rugged in construction and economical to manufacture.
  • FIG. 1 is a top side perspective view of a magazine constructed in accordance with the invention
  • FIG. .2 is a longitudinal sectional view of the magazine indicated in FIG. 1;
  • FIG. 3 is a transverse section of a gun barrel having a magazine therein constructed in accordance with the invention
  • FIG. 4 is an enlarged partial bottom plan view of the gun indicated in FIG. 3;
  • FIG. 5 is a partial longitudinal vertical sectional view of a gun constructed in accordance with the invention.
  • FIGS. 6, 7 and 8 are views similar to FIG. 5 showing the operating parts of various positions of operation.
  • FIGS. 1 to 4 the invention embodied therein in FIGS. 1 to 4 comprises a magazine for cartridges or pellets which includes a block-shaped container 1 having a closed end 1a and an opposite open end 6 into a portion of which projects a resilient tongue or tab 8. Projectiles such as pellets 3, are loaded into the open end 6 by depressing the tongue outwardly. The pellets 3 rest on a follower or support 4 which is biased toward the open end by a spring 2 arranged between the bottom la and the follower 4. A claw or tooth projection 7 on the tongue 8 holds the pellets 3 within the magazine against the force of the spring 2.
  • a gun barrel 20 is provided with a bottom magazine receiving frame 11 which is arranged around the lowermost opening of a magazine channel 15.
  • the frame 11 carries a transverse stopper 13 on a central receiving flat spring 12 which is deflected outwardly by an insertion of the magazine but which engages in a groove 10' defined in a side wall of the magazine when the magazine is properly positioned in respect to the gun.
  • the tongue 8 is pointed so that it will be deflected by a nose or projection '14, defined at the upper (inner) end of the barrel magazine channel, to
  • the magazine advantageously includes an elongated slot 9 defined in a side wall through which a pin or indicator member 5 extends. Indications or markings defined along the length of the slot provide an indication of a number of cartridges within the magazine as shown by the position of the pin 5 which is formed as an extension of a portion of the follower 4.
  • FIGS. 5 to 8 there is indicated a gun of the type shown in FIG. 3, showing the various positions of the operating mechanism for firing a projectile through a bore 20' of the barrel 20.
  • the operating mechanism includes a sliding bolt or sleeve member generally designated 29 having a central bore or gas passage 29 therethrough which is concentrically arranged within the bore 20' of the barrel 20.
  • the barrel 20 includes an intermediate recess or spring cavity 23 having a slot 50 through which projects a bolt handle 30 of the bolt 29.
  • a bolt spring 34 is disposed around the bolt member 29 between the forward end of the cavity 23 and the bolt handle 30 and it is compressed in the cocked position indicated in FIG. 5.
  • an arm portion 36 of a trigger mechanism 35 is engaged against a latching portion 31 of the bolt 29 which is in alignment with the bolt handle 30 to hold the sleeve member in a position at which the firing spring 34 is compressed.
  • a trigger spring 38 urges the arm portion 36 into a latching engagement with the latch portion 31.
  • This narrow sealing chamber 25 communicates rearwardly into a gas chamber 27 when a closing valve 39 is lifted olf its seat against the force of a compression spring 41 tending to hold it on its seat.
  • the lifting is effected by the rearward movement of the sleeve member 29 which contacts a valve stem 40 to effect the lifting of the valve 39 off its seat 26.
  • the gas chamber 27 communicates with a main gas chamber 22 having a gas under pressure such as a C gas, which is supplied, for example, from an inexpensive CO container.
  • the gas flows through a restricted passage 21 into the auxiliary gas chamber 27.
  • the gas passages 3-2, 24, 25 and 29' form a passage means for the gas under pressure to flow from the valve 39 to the bore 20'.
  • the opening of the valve 39 causes a gas flow into the sealing chamber 25 and causes the forward movement of the sleeve member 29 to compress its associated spring 34 and to move the latch 31 beyond the trigger arm portion 36 so that it will be re-engaged therewith to recock the gun.
  • the transverse passage will also communicate through the annular passage 24 with the gun under pressure which will be admitted through the gas passage 29 to force the pellet through the barrel board 20' out of the gun toward the target (FIG. 8).
  • the FIG. 8 position corresponds to that of the FIG. position so that the gun is again cocked ready for firing the next round.
