Gas operated pellet gun with removable clip loader

Claim 2

A gun comprising a frame, a barrel mounted on said frame, a bolt reciprocable in said frame in axial alignment with the bore of said barrel, means for effecting reciprocation of said bolt, an indexing shaft rotatably mounted in said frame in offset parallel relation to said bolt, means connecting said bolt to said shaft to rotate said shaft in opposite directions upon movement of said bolt in opposite directions, respectively, said frame having a chamber therein adapted to receive a removable clip, which has therein a rotatable cylinder containing a plurality of pockets for holding projectiles, said chamber being so positioned in said frame that when a clip is positioned therein one of the pockets of the clip will be in axial alignment with the bore of said barrel and with said bolt, said frame having an opening therein through which a clip may be inserted into or removed from said chamber, a one-way coupling member secured to said indexing shaft to couple said shaft to a clip positioned in said chamber, for indexing rotation of said coupling member in one direction with said shaft on movement of said bolt rearwardly, said bolt entering the pocket of said cylinder which is then aligned with said barrel, on movement of said bolt forwardly, to push a projectile from that pocket into the barrel, and to hold the cylinder against rotation as long as the bolt is in that pocket.

Claim 3

A gun as claimed in claim 1, having a chamber for holdInG a supply of compressed gas, a duct for conducting gas from the last-named chamber into said barrel behind a projectile disposed in said barrel to fire the projectile from said barrel, a valve normally closing said last-named chamber off from said duct, a trigger-releasable hammer operative, upon release thereof, to open said valve, and means for simultaneously cocking said hammer and said bolt and effecting indexing rotation of said shaft.

Claim 4

A gun as claimed in claim 2, wherein the last-named means is a cocking rod reciprocably mounted in said frame in parallelism with said bolt.

Claim 5

A gun as claimed in claim 1, wherein said coupling member is a ratchet-toothed face coupling member, and said cylinder has on it a cooperating ratchet-toothed face coupling member, whereby said cylinder is indexed a fraction of a turn each time said bolt is moved rearwardly.

Claim 6

A gun as claimed in claim 1, wherein the means connecting said bolt and shaft comprise a cam and a pin engaging therewith.

Claim 7

A gas-operated gun, comprising a hollow frame containing a valve block, a barrel fastened at its rear end in said block, a projectile clip removably mounted in said frame rearwardly of said block, a cylinder rotatably mounted in said clip and having therethrough a plurality of projectile chambers each of which is adapted to hold a projectile, said chambers being equi-angularly spaced about the axis of said cylinder to register one by one with the rear end of said barrel upon rotation of said cylinder, a hammer in said frame movable between cocked and first positions, trigger-operated means in said frame operative to admit a supply of gas under pressure to the rear of a projectile in said firing position each time said hammer is moved to its fired position, thereby to propel the last-named projectile from the barrel, manually operable cocking means for moving said hammer to its cocked position, indexing means interposed betWeen said cocking means and said cylinder and operative to index said cylinder a fraction of a revolution in one direction each time said cocking means is operated, thereby to rotate one of said chambers out of registry with said barrel and to move the next successive chamber in said cylinder into registry with said barrel, and means connected to said cocking means and operable thereby to transfer a projectile from a chamber in said cylinder to firing position in said barrel each time a chamber is moved into registry with said barrel, said indexing means comprising a clutch member mounted in said frame for oscillation by said cocking means about an axis parallel to said barrel, said clip comprising a casing removably insertable through an opening in said frame into a space formed in said frame between said block and a transverse partition in said frame to position said cylinder in coaxial registry with said clutch member with adjacent ends of said cylinder and clutch member confronting one another through an opening in said casing, and cooperating clutch faces formed, respectively, on the confronting ends of said cylinder and said clutch member, and resiliently engaged with one another to impart the rotation of said clutch member to said cylinder in said one direction only, said indexing means further comprising a shaft mounted in said frame rearwardly of said space to oscillate coaxially of said axis, said clutch member being coupled to said shaft coaxially thereof for rotation by said shaft in an opening in said partition, and for limited axial movement relative to said shaft and the last-named opening, and a spring being interposed between said shaft and said clutch member resiliently to urge said clutch member axially on said shaft in a direction to maintain said clutch faces in resilient engagement, with said casing is disposed in said space.

Claim 8

A gas-operated gun, comprising a hollow frame containing a valve block, a barrel fastened at its rear end in said block, a projectile clip removably mounted in said frame rearwardly of said block, a cylinder rotatably mounted in said clip and having therethrough a plurality of projectile chambers each of which is adapted to hold a projectile, said chambers being equi-angularly spaced about the axis of said cylinder to register one by one with the rear end of said barrel upon rotation of said cylinder, a hammer in said frame movable between cocked and first positions, trigger-operated means in said frame operative to admit a supply of gas under pressure to the rear of a projectile in said firing position each time said hammer is moved to its fired position, thereby to propel the last-named projectile from the barrel, manually operable cocking means for moving said hammer to its cocked position, indexing means interposed betWeen said cocking means and said cylinder and operative to index said cylinder a fraction of a revolution in one direction each time said cocking means is operated, thereby to rotate one of said chambers out of registry with said barrel and to move the next successive chamber in said cylinder into registry with said barrel, and means connected to said cocking means and operable thereby to transfer a projectile from a chamber in said cylinder to firing position in said barrel each time a chamber is moved into registry with said barrel, said indexing means comprising a clutch member mounted in said frame for oscillation by said cocking means about an axis parallel to said barrel, said clip comprising a casing removably insertable through an opening in said frame into a space formed in said frame between said block and a transverse partition in said frame to position said cylinder in coaxial registry with said clutch member with adjacent ends of said cylinder and clutch member confronting one another through an opening in said casing, and cooperating clutch faces formed, respectively, on the confronting ends of said cylinder and said clutch member, and resiliently engaged with one another to impart the rotation of said clutch member to said cylinder in said one direction only, said indexing means further comprising a shaft mounted in said frame rearwardly of said space to oscillate coaxially of said axis, said clutch member being coupled to said shaft coaxially thereof for rotation by said shaft in an opening in said partition, and for limited axial movement relative to said shaft and the last-named opening, and a spring being interposed between said shaft and said clutch member resiliently to urge said clutch member axially on said shaft in a direction to maintain said clutch faces in resilient engagement, with said casing is disposed in said space.
