Definitions

  • This invention relates to the breech action of guns and more particularly to means "uNlTEDcsTA-TES 'PATENT OFFICE.
  • the principal objects of the present in vention are to render the action of breech closures free and uniform, to render uniform and reliable the action of mechanisms for locking breech closures in closed position, and more particularly to apply lubricant automatically and uniformly to the sliding surfaces of thevarious parts of breech actions.
  • Figure 1 is a central vertical longitudinal section of a gun embodying the present invention
  • Fig. 2 is a vertical transverse section on line 2 2 of Fig. 1;
  • Fig. 3 isa horizontal longitudinal section on line 3-'3 of Fig. 1.;
  • a U-shaped clip C whichas shown in Figs. 1, 2 and 3 .comprises a base lportion abutting against the rearward end of the receiver chamber and two forwardly projecting arms which lie in the grooves or guidewavs g and g in the opposite sides of the receiver chamber.
  • Mounted in the spaces betweenthe arms of the spring clip and the walls of the receiver chamber are lubricant carrying pads P and P', the upper and lower edges of the arms ofthe spring clip being bent outwardly over the upper and lower edges of the pads to secure the pads to the clip.
  • the forward ends of the pads project beyond the forward ends of the clip arms and the one embodicli is of such length that' these wardly outside of the grooves g and g the.
  • the lubricating means is preferably yieldlng to accommodate the slight variations 1n the maximum recoil of the bolt due to the different degrees of compression of the bufferand 1n the illustrated embodiment this yieldingness is afforded by the elastic character of the pads themselves.
  • the buffer J is disposed between the arms of the spring clip and fits over a plunger X having a portion extending rearwardly through an opening in the face of the clip and thence into an opening in the rear of the receiver.
  • the spaces between the forward end of the plunger X and the forward end of the tubular buffer, J is filled with disks Q of leather or other suitable shock absorbing material so that vwhen the rear end of the bolt B engages the shoulder 7' on the buffer the tubular member J slides rearwardly on the plunger, thereby compressing v tion.
  • Figs. 4 to 7 is shown a slightly modified form of lubricating clip.
  • the arms of this clip are bowed outwardly at Z and Z so as to ⁇ engage the bottoms of the guideways g and g', thereby more accurately to position the clip in the receiver.
  • This clip is provided with an opening O in its base, as in the first embodiment, to receive the plunger of the buffer.
  • the upper and lower edges of the arms are bent over as shown at nf-n and 'n/-n' to secure the lubricating pads P and P in position.
  • the arms are cut awa at the forward ends as illustrated at U in ig. 7 and the forward ends of the pads P and P terminate intermediate the ends of these cut away portions along oblique faces V which are inclined at the same angles as the rear faces of the locking lugs Z and Z so as to contact with the lugs throughout their entire rearward faces.
  • Lips W and W are struck up from the arms of the clip immediately in the rear of the lubricating Ipads to assist the bent edges bi1-fn and w/ fn/ in holding the pads in posi- Spurs u and u are also struck up osition.
  • This transmission of lubricant to the lock is repeated each time the bolt recoils and in the forward and rearward movement of the bolt and lock relative to the receiver and in the transverse movement of the lock relative to the bolt and receiver the lubricant applied to the lugs is distributed over all of the sliding surfaces of the bolt lock and receiver. In this way a uniform and reliable lubrication of all of the sliding surfaces of the breech action is gained.
  • the lubricating pads may be replenished with oil from time to time either through oil holes provided in the receiver or by sliding the frame F rearwardly off the receiver, but I have found that many thousands of shots may be fired without replenishing the pads with oil.
  • a gun comprising a receiver having a breech chamber, a breech closure movable in saidl chamber, the breech closure having a locking lug movable in a groove in said chamber, and a lubricant-carrying body mounted in said groove to contact with said lug when the closure is retracted.
  • a gun comprising a frame, a breech closuremovably mounted in said frame, and a lubricant carrying body mounted on the frame along the path of travel of the closure so as to contact with the' closure when opened and thereby to transmit lubricant thereto.
  • A- gun comprising a frame having a breech chamber therein, a breech closure:
  • a gun comprising a frame, ⁇ a breech closure movably mounted in said frame, and means on the gun for lubricating the breech closure, said means comprising a lubrlcantcarrying body arranged to contact wlth the closure when wide open.
  • a gun comprising a frame, a breech closure mounted in sald frame to reciprocate forwardly ⁇ and rearwardly between open and closed position, and a lubricant carrying body disposed behind said closure to contact therewith when the closure is 1n open osition.
  • gun comprising a frame, a breech closure mounted in the frame to move into and out of closed position, the frame and breech closure having coperating abutments for locking the closure in closed position, and means for applying lubricant to said abutments each time the closure isv actuated.
  • a gun comprising aframe, a breech closure mounted in the frame to move into and out of closed position, the frame .and breech closure having coperating abutments for locking the closure in closed position, and means disposed along the path of said closure for applying lubricant to the abutment thereto each time the closure is actuated.
  • a gun comprising a frame, a breech closure mounted in the frame to move into and out of closed position, the frame and breech closure having coperating abutments for locking the closure in closed position, and a lubricant vcarrying body disposed in the path of the abutments on the closure so as to contact therewith and appl lubricant thereto each time the closure is opened.
  • a gun comprising a frame, -a breech closing bolt mounted in the frame to recipapplying lubricant to said loc Vclosure mounted in said chamber to reciprocate forrocate forwardly and rearwardly between open and closed positions,lo'cking lugs carried ,by the bolt in its -longitudinal central region for locking the bolt in closed-position, and means for applying lubricant to said lugs from whence the lu ricantmay ,be distributed forwardly and rearwardly from said longitudinal central region along the sliding surfaces of the bolt.
  • a gun comprising a frame, a breech closing bolt mounted in the frame to reciprocate ⁇ forwardly and rearwardly between open and closed positions, a lock movable transversely of the bolt to lock the bolt in closed position, and means for automatically gun comprising a frame, a breech 1 movable invsaid frame into and out of breech closing position, a U-shaped clip straddling the path of said closure, and lubricant carrying bodies mounted on the arms of said clip 1n position to apply lubricant to opposite sides of said closure.
