Description
- The present application is related to and claims priority to U.S. Provisional Patent Application, Ser. No. 61/942,883, filed on Feb. 21, 2014, entitled “Fluid Cartridge Powered Pellet Gun.” The subject matter disclosed in that provisional application is hereby expressly incorporated into the present application.
- The present disclosure relates to fluid powered pellet guns, and particularly, to a gun that receives a fluid filled cartridge that fires a pellet carried on the cartridge upon actuation of a trigger.
- An embodiment of the present disclosure describes a pellet gun that fires a pellet from an air-filled cartridge. In one embodiment, the cartridge exhausts substantially all of its air pressure while firing the pellet to provide a high velocity projectile. Once the pellet is fired the cartridge may be removed from the firing mechanism and replaced with another. Each cartridge is configured to removably hold a pellet on its end. When inserted into the breach end of the gun and pressing the trigger, a firing pin engages the cartridge which fires the pellet. After the pellet is fired, the cartridge may be removed from the gun's barrel and a charged cartridge and pellet reinserted on its end. It is appreciated that one embodiment of such a gun may have the visual appearance of a Winchester High Wall rifle. It is further appreciated that other embodiments of the gun may have different appearances.
- In another embodiment, a pellet such as a 78 grain pellet may be fired from a cartridge of the present disclosure at about one thousand feet per second. The cartridge may illustratively have about 4,500 psi pressure. It is appreciated that having gas or air in the cartridge may make the gun lighter considering the fire power in comparison to a pellet gun employing a standard canister or tank.
- Another illustrative embodiment of this disclosure includes a gun such as that previously described where the pellet is fired through a barrel liner. In the illustrative embodiment, the barrel may be made of two components—an outer barrel and an inner barrel liner. The inner barrel liner fits within the outer barrel. Illustratively, the outer barrel may be made of aluminum, while the barrel liner is made of steel. This allows the pellet to be fired through the steel bore supported by the lighter outer barrel. This has the effect of reducing the overall weight of the gun.
- Another illustrative embodiment of the present disclosure includes a refill system for the aforementioned cartridges. It is contemplated that in an embodiment the cartridges that fire the pellet are reusable. The cartridges may be refilled with air and a pellet after each use. In an illustrative embodiment, a fill chamber mechanism receives the cartridge and fills its interior chamber with air. It is appreciated that this system may recharge one or more cartridges at one time.
- Another illustrative embodiment of the present disclosure provides a pellet gun that comprises a gun and a cartridge. The gun includes a trigger, and a barrel. The barrel has a breach end. The cartridge is selectively positionable at the breach end of the barrel and includes an opening configured to selectively hold a pellet. The cartridge is also located inside the pellet gun such that when the cartridge is selectively holding the pellet the pellet is located in the barrel, and is selectively filled with a pressurized gas. The trigger initiates engagement with the cartridge to cause the gas in the cartridge to be exerted against the pellet which is fired through the barrel.
- In the above and other embodiments, the pellet gun may also comprise: a firing pin that engages the cartridge which fires the pellet; the cartridge being removable from the breach end of the barrel; the cartridge being removable from at least a portion of the barrel of the gun; the barrel of the gun including a barrel liner located in the barrel wherein the barrel is made of aluminum and the barrel liner is made of steel; the cartridge being refillable and reusable by refilling the cartridge with the gas; the gas being selected from the group consisting of nitrogen, carbon dioxide, and air; the gun further including a receiver, hammer, sear, trigger knuckle, knuckle, breach block, firing pin, lever, and a stock; the cartridge being formed from a tubular body having a pellet plug located at and opening located at one end configured to selectively hold the pellet; the cartridge including a cartridge tube having a chamber located therein; a firing pin plug that includes a bore disposed there through and configured to receive a valve pin; the firing pin plug coupling to the cartridge tube, a seal configured to position about the valve pin and fits in the bore to provide selective sealing between the valve pin and exterior of the cartridge, a plunger coupled to the valve pin and seal engages a spring which provides a bias force against the firing pin plug, wherein the spring also fits in a cavity in a piston head of a piston, a passage opening located in the piston head, wherein the piston also includes a piston rod that extends from the piston and terminates at a piston plug, and an O-ring about the opening to hold the pellet prior to firing; the cartridge being charged with the gas by the gas entering the cartridge through the bore in the firing pin plug, wherein the gas biases the valve pin, the gas then enters a second cavity in the piston head and then through a passage opening which fills the chamber in the cartridge until the chamber is full, wherein the cartridge is configured such that once the chamber is full back pressure and bias from the spring pushes against the plunger, seal, and valve pin to close the opening in the bore of the firing pin plug, wherein the gas in the chamber is in fluid communication with the cavity and the piston head, wherein the piston plug of the piston is configured to block the opening at the pellet plug, and wherein when the chamber is charged; wherein the cartridge is configured that when being actuated by the gun, the valve pin of the cartridge is moved by a firing pin in the gun, wherein the gas located in the cavity of the piston head escapes which causes the piston to move towards the firing pin plug, wherein movement of the piston causes the piston plug to move from the opening in the pellet plug, wherein this causes the gas in the chamber to apply a force against the pellet located in the opening, wherein the force of the gas applied to the opening is greater than back through the bore because the passage between the opening and the bore are not configured to allow enough of the gas to pass through, wherein the O-ring that holds the pellet at the opening is not strong enough to withstand the force of the gas exiting from the chamber which causes the pellet to be projected from the opening, and wherein the piston retracts to react to the bias of the spring which causes the plunger to push the seal against the bore in the firing pin plug to seal the bore; wherein the gun is configured to fire the pellet from the cartridge, wherein the cartridge is positioned into a firing chamber that is in communication with the barrel, wherein the brake block is moved via connection to the knuckle to expose the chamber which also moves the hammer to allow insertion of the cartridge into the firing chamber, and wherein the brake block and hammer are moved again after the cartridge is inserted into the firing chamber, wherein the hammer is moved to its firing position, wherein the hammer is configured to direct the firing pin to engage the valve pin in the cartridge when the trigger is pressed which causes the sear to release the trigger knuckle from the hammer which engages the firing pin which in turn engages the valve pin of the cartridge which fires the pellet.
- Another illustrative embodiment of the present disclosure provides a pellet gun that comprises a gun and a cartridge. The gun includes a trigger and a barrel, where the barrel has a breach end. The cartridge is selectively insertable into the gun and directed to the breach end of the barrel, and includes an opening configured to selectively hold a pellet. The cartridge is also located inside the pellet gun such that when the cartridge is selectively filled with a pressurized gas and selectively holds the pellet toward the barrel.

It is appreciated that the air may enter all around the movedvalve pin 54 to enterbore 52. At this point, the air also enterscavity 66 inpiston head 64. The air is then free to escapepiston head 64 throughpassage opening 84 and fillchamber 48, as indicated bydirectional arrow 96. The process continues until thechamber 48 is full. At this point, back pressure andspring 62 pushes againstplunger 60,seal 58, andvalve pin 54 to close any opening inbore 52 offiring pin plug 50.Seal 58, being biased againstbore 52 byspring 62 ensures air does not leak out.Cartridge 4 is thus charged as shown inFIG. 6 . - The view of
cartridge 4 shown inFIG. 6 is charged with air inchamber 48 and is now ready to be inserted intogun 2 for firing, as shown inFIGS. 11 and 12 . As demonstrated byFIG. 6 , however, plunger 60 along withseal 58 is biased againstbore 52 byspring 62, thereby preventing air from escaping out ofcartridge 4. It is appreciated from this view that air inchamber 48 is in fluid communication withcavity 66 andpiston head 64. At the other end ofcartridge 4, piston plug 74 ofpiston 68 blocks opening 22 atpellet plug 20. With the aid of O-ring 76, none of the air inchamber 48 can exit into the end ofpellet plug 20.Pellet 6 is being held into place by O-ring 80. In this illustrative embodiment, both firingpin plug 50 and pellet plug 20 are threaded to mate with corresponding threads at the ends ofcartridge 4 as shown by this view. At this point, and as previously mentioned and described further herein, when in this state,cartridge 4 is in condition to be inserted intogun 2 to firepellet 6. - The cross-sectional side view of
cartridge 4 shown inFIG. 7 demonstrates howcartridge 4 operates when being fired. In this view,first valve pin 54 is pushed indirection 90 by afiring pin 34 shown further herein inFIGS. 13 and 14 . When this happens, air located incavity 66 ofpiston head 64 escapes first, as indicated bydirectional arrow 98. When this happens,piston 68 moves or collapses indirection 92 towardsfiring pin plug 50. (Compare relative positions ofpiston 68 inFIGS. 6 and 7 .) Becausepiston 68 is of a finite length, when it moves indirection 92, piston plug 74 is removed from opening 22 inpellet plug 20. This causes the air that is inchamber 48 to quickly escape from opening 22, as indicated bydirectional arrow 100. The air releases more from opening 22 than back throughbore 52 becausepassage opening 84 betweenopenings passage 84, so the path of least resistance ends up beingopening 22. - The cross-sectional view of
cartridge 4 shown inFIG. 8 demonstrates its operation whenpellet 6 is fired therefrom. As shown therein,pellet 6 is fired from opening 22 ofpellet plug 20. O-ring 80 that assists seatingpellet 6 in opening 22 is not strong enough to withstand the force of air that exits fromchamber 48 out throughopening 22.Piston 68 is shown retracted indirection 92, which along withspring 62, causesplunger 60 to pushseal 58 againstbore 52 infiring pin plug 50, thereby sealingbore 52. It is appreciated that the air pressure may be sufficient enough, such as 4,500 psi, to fire a 78 grain pellet at about 1000 feet per second. Changing the fill pressure, pellet weight, and barrel design may change this number. - The views shown in
FIGS. 9 through 14 demonstrate howgun 2 shoots apellet 6 fromcartridge 4. The side cross-sectional view of a portion ofgun 2 is shown inFIG. 9 . The shown position is a start position wherechamber 102 ofreceiver 10 is closed,hammer 24 is released, and nocartridge 4 is in the gun. This view also shows howcartridge 4 is sized to fit intochamber 102 that is in communication withbore 104 through whichpellet 6 travels when fired. - The side cross-sectional detailed view of
receiver 10 portion ofgun 2 is shown inFIG. 10 wherechamber 102 is open and configured to receivecartridge 4. By pullingguard lever 36 indirection 106, breakblock 32 is pulled downward via connection withknuckle 30 to exposechamber 102 as shown. This also pullshammer 24 out of the way as well. The view shown inFIG. 11 is similar to that of 10 except herecartridge 4 is being inserted intochamber 102 ofreceiver 10. As shown, breakblock 32 andhammer 24 are out of the way of the path of travel ofcartridge 4.Hammer 24 is also cocked when moved to the shown position. Oncecartridge 4 is inserted intochamber 102, as the side cross-sectional view ofFIG. 12 shows,guard lever 36 may be pivoted back indirection 108 to raisebreak block 32 andhammer 24 to their original position. - The view in
FIG. 13 showslever 36 in its use position. When this happens, hammer 24 does not move back to its original position, since it is located in its cocked position. Being in the cocked position, only manual release or pullingtrigger 14 will releasehammer 24. As shown in this view, firingpin 34 is directed tovalve pin 54 incartridge 4. Here the gun is in condition for firing, but has not yet fired. The view shown inFIG. 14 demonstrates the gun's action whentrigger 14 is pulled. When that happens, trigger 14 causes sear 26 to releasetrigger knuckle 28 fromhammer 24 which engages firingpin 34 which engagesvalve pin 54 to opencartridge 4 as described with respect toFIGS. 7 and 8 as previously discussed. Accordingly,air exiting opening 22fires pellet 6 throughbore 104. It is appreciated thatcartridge 4 may be refilled as previously discussed, andgun 2 recycled as also previously discussed, to prepare another pellet for firing. - Although the present disclosure has been described with reference to particular means, materials and embodiments, from the foregoing description, one skilled in the art can easily ascertain the essential characteristics of the present disclosure and various changes and modifications may be made to adapt the various uses and characteristics without departing from the spirit and scope of the present disclosures.
