- This invention relates to an automatic machine-gun in which the barrel moves backwardly when a cartridge is fired and after compressing the operating-spring is drawn forward by the spring, while the breech-block moves farther backward for extracting the exploded shell and permitting the feeding of another cartridge into position for loading into the barrel, when the breech block is thrown forward, the breech-block being released for this purpose when the cartridge is properly fed.
- the object of this invention is to simplify and make durable the mechanisms of such a gun, whereby the action will be positive and reliable.
- the embodiment of the invention illustrated in the accompanying drawings has a barrel and a connected frame which move backwardly together and compress a spring when a cartridge is tired.
- the breech-block, bearing the spring firing-pin first moves backwardly with the barrel-frame and then by means of intermediate mechanisms is moved farther back along the frame away from the breech as the barrel and frame are drawn forwardly.
- a spring is made tense by the backward movement of the breech-block, and a catch engages parts connected with the breech-block for holding it back against the force of the spring.
- the hammer, scar, and hammer-spring are borne by the frame, and the hammer is cocked by the movement of the breech-block away from the breech.
- the cartridges are allowed at the proper time to drop by gravity through the side of the case onto a transverse feeder that is held in place against the force of a spring by a latch that is released from a catch by the weight of the dropping cartridge.
- This feeders wings transversely on a pivot and carries the cartridge into line with the barrel in front of the breechblock, and as the cartridge reaches the proper line a part of the feeder engages connections that release the breech-block catch and allow the block to be thrown forward and push the cartridge that has been fed in front into the breech of the barrel.
- the trigger engages a part connected with the finger-pull at the butt of the gun, which if drawn causes the trigger to disengage the sear from the hammer and allow the hammerspring to throw the hammer and drive forward the pin into the primer of the cartridge that has been loaded into the barrel.
- the backward movement of the breech block opens the passage, so that a following cartridge may be dropped upon the transverse feeder, and a part of the feeder closes the passage when a cartridge is being placed in front of the breech-blook.
- the forward movement of the breech-block forces back the feeder into position to receive the next cartridge.

- the case that incloses the mechanisms is octagonal in transverse section and is formed with a trunnion-band 1 and a butt-plate 2, between which extend ribs 3, Figs. 1 and 2.
- These ribs have undercut grooves, and slidingin the grooves are panels 4, Figs. 6 and 7.
- Either or all of these panels may be slid out from the back, so as to permit ready access to the mechanisms contained in the case.
- the trunnions 5 are held by boxes 6 at the upper end of the head-yoke '7, that is supported by any suitable mount 8.
- a threaded sleeve 11 that is provided with a hand-wheel12 and a clamp-handle 13.
- a tube 14 extends from thehead of the mount through the sleeve 11.
- a handle 15 At the end of the tube is a handle 15, and when this is loosened the gun and the head may be freely rotated upon the mount. Any desired sights 16 and 17 may be attached to the top of the casing, and a suitable shoulder-piece 18 may be fastened to the end. A hand-grip 19 is attached to the butt of the case, and this supports a finger-pull 20, Figs. 1, 2, and 3.
- a pair of posts 21 are secured to the front endof the case,and at the outerends of these is a cross-head 22.
- the barrel 23 is loosely su pported by the front end of the case and the cross-head 22, Figs. 1 and 2.
- An arm 24 is fastened to the barrel, and attached to the arm is a rod 25, that extends through the case, and in a cylinder 26 is fastened to a piston 27, Figs. 1, 2, 4 and 5.
- the cylinder 26, which is located in a chamber 28 in the upper front end of the case, is open at both ends to the fluid that fills the chamber.
- A- valve 29 is supported by the forward end of the case so as to be movable toward and from a passage 30 between the ends of the cylinder. This valve is thrust with a yielding pressure toward the passage 30 by a spring 31 and is limited in its movement toward the passage by the end of a rod 32, Fig. 4.
- This rod extends from the chamber to the butt of the gun, Where it may be connected with any suitable means for adjusting it lengthwise.
- suitable means form the subject-matter of United States application for patent, Serial No. 714,389, filed by me on April 25, 1899, and are not herein described in detail.
- a rod 34 Fastened to the frame 33, attached to the breech of the barrel, is a rod 34, that on its front end is provided with a nut 35, Fig. 2.
- a spring 36 On this rod is a spring 36, one end of which thrusts against the nut 35 and the other end thrusts against a collar 37, connected with the upper end of a lever 38, Fig. 5.
- the thrust of this spring between the nut and collar forces the barrel forward, and the power of this thrust depends upon the position of the collar, which is changed along the rod by the lever as the elevation or depression of the muzzle of the barrel is altered.
- This mechanism forms the subject of United States application for patent,Serial No. 7l4,511,filed by me on April 26, 1899, and is therefore not herein described in detail.
- breech-block 40 Movable in a guideway 39 in the frame that is fastened to and is movable with the barrel is the breech-block 40.
- a recoil-block 41 is secured to the rear ends of the yoke 42, which is pivoted to the breech-block.
- breech-block is home, the yoke-arms hold the recoil-block in line with the axis of the barrel When the.
- the lower ends of the breech-block yokearms 44 are connected by a rod 45 with the lower ends of a yoke 46, that at its upper end is connected with the barrel-frame.
- the frame-yoke is connected near the middle of its length by links 47 with rocker-arms 48, that are secured on the tranverse shaft 49, the links 47 and the rocker-arms 48 forming a toggle connection between the shaftand the frame-yoke, Figs. 4, 5, and 8.
- a spring 50 is wound upon the shaft 49 in such manner as to rotate the shaft in a direction that will throw the rocker-arms forward.
- One end of this spring is engaged with a stud 51, projecting from a part of the case, and the other end is engaged with a disk 52, that is adjustably connected with the shaft, so that the tension of the spring may be regulated, Figs. 4 and 7.
- the breech-block remains back until the rocker-arms are released and the spring upon the shaft throws the arms forward, which action causes the breech-block to be moved close to the breech of the barrel and the recoil-block to drop into position in front of the recoil-shoulder, Fig. 8.
- the transverse feeder 56 is pivoted upon a stud 57, fastened to the front end of the case.
- This feeder has a ridge or shelf 58, that extends rearwardly beneath the opening 59 through the wall of the case, into which the cartridges drop from the feed-case, Figs. 6, 10, and 13.
- Extending above this shelf is a back 60, and projecting to one side from the back edge is a flange 61, that when the feeder is moved to feed a cartridge obstructs the passage and prevents the entrance of the following cartridge.
- the back and shelf of the feeder are shaped to properly support and carry the cartridges.
- a spring 62 wound about the stud, Fig. 5, tends to force the upper end of the feeder toward the center, so as to carry the cartridges into line with the breech-block and bore of the barrel.
- the entire shelf 58 of the feeder upon which the cartridge is dropped may be hinged to the feeder, as illustrated in Figs. 13 and 14, or only a part 96 of the shelf may be hinged to the back 60, the part 97 being fixed to the back, as illustrated in Figs. 10, 11, and 12. If the entire shelf is hinged to the feeder, springs 64, Figs. 13 and 14, may be employed to hold the inner edge of the shelf raised so that the edge will engage with a catch-lug 65, that is secured to the front wall of the case, Figs. 6, 13, and 14.
- a hook 92 projects from the back of the movable part 96 of the shelf and is arranged to engage a catch 93, fastened to the case.
- the weight of a cartridge will depress the movable part 96 of this form of shelf against the thrust of the springs 66 and release the engagement of the catch and latch hooks.
- the latch-hook 94 is formed as part of a lever 67, pivoted to ears projecting from the feeder.
- the upper end 93 of the inner part of the lever extends slightly above the immovable fioor 99 of the shelf, so that it will be depressed by the weight of a cartridge for disengaging the hooks.
- the weight of a cartridge dropping upon the movable part of the shelf causes that part to be depressed, and this releases the latch, so that the feeder may be thrown forward to carry the cartridge into line with the breech-block.
- a finger 68 Projecting from the lower end of the feeder is a finger 68, which is located and arranged to engage a finger 69 when the cartridge is in front of the breech-block and in line with the bore of the barrel, Figs. 6, 7, and 13.
- finger 69 projects from the shaft 55, that is provided with the finger 54, which engages the shoulder 53 for holding the rocker-arms and keeping back the breech-block when the barrel and frame are moving forward.
- the engagement of the finger 68 of the feeder with the finger 69 of the shaft 55 rocks that shaft, so that the finger 54 is withdrawn from the shoulder, and the rocker-arms are free to move forward under the impulse of the coiled spring 50 on the shaft 49 and throw the breechblock home, loading into the barrel the cartridge which has been placed in front by the movement of the feeder that released the breech-block parts.
- the trigger-pull 20, supported by the handgrip 19, is connected by a rod 70 with a sleeve 71, placed upon the shaft 55.
- This sleeve is normally thrust forward by a spring 72, and to its forward end an arm 73 is fastened, Figs. 4 and 5.
- the trigger 95 which is an angle-lever, is pivotally supported in an opening formed in the rod 45, that joins the breech-block yoke with the frame-yoke.
- a spring 74 placed in the opening, thrusts the lower end of this trigger forward, so that its upper rear end is held down.
- the scar 75 is carried in a mortise in the frame attached to the barrel, and a spring thrusts the rear end 101 of the sear toward the trigger and holds the front end 102 of the sear in position to engage the shoulder 103 on the edge of the hammer-block 76, which is pivoted in the same mortise.
- the upperend of the hammer extends between the arms of the yoke 42 into the path of the breech-block 40, and as the breech-block moves backwardly it forces back the hammer against the thrust of the hammer-spring 77 until the end 102 of the sear engages the shoulder 103 and holds the hammer cocked.
- the upper rear end of the trigger will be lifted, so as to raise the end 101 of the sear, and this causes the other end 102 of the sear to be drawn down out of engagement with the shoulder 103, leaving the hammer free to be thrown for- IIO i seem? wardly by the spring 77 for striking the firingpin, Fig. 18.
- the lower end of the trigger in its forward movement with the rod 45 will engage the arm 73 just after the breech-block reaches its forward position and is secured close against the breech of the barrel, if the trigger-pull is drawn back, and be held in such manner that the continued forward movement of the parts will cause the trigger to disengage the sear from the hammer, Fig. 1.8.
- the hammer when thrown forward strikes the firing-pin 78, that is carried in a recess in the breech-block.
- This firing-pin is thrust forwardly by a spring 104.
- extractor-bars 80 that have fingers 105 at their front ends for grasping the heads of the cartridges and drawing the shells out of the barrel when the breech-block moves backward and opens the breech.
- a lever 81 is pivoted in an opening in the breechblock, so that one end enters a slot 106 in the firing-pin and the other enters a slot 107 in the upper extractor-bar.
- a spring 79 in a recess in the breech-block forces back a plate 109,
- the spring 79 draws back the extractor-bars, so that the fingers will grasp and hold the rim of the cartridge-head.
- the backward movement of the upper extractor-bar moves the lever 81, so that the firing-pin will be pressed forward by its spring 104 in position to be driven into a primer when the firing-pin is struck by the hammer.
- a gate 83 Mounted upon the shaft 32, adjacent to the cartridge-feeding opening 59, is a gate 83.
- a spring 84 coiled about the shaft, holds the gate sufficiently in front of the opening to prevent cartridges from. dropping through onto the transverse feeder at an improper time.
- This gate has an arm 85, that by contact with a portion of the case limits the downward movement of the gate.
- a wedge 86 is formed on a part projecting from the lower portion of the gate, and this is arranged to be engaged by an inclined surface on a part 87, that projects from the breech-block when that block moves backwardly, Figs. 4, 6, 7, 10., and 13. The engagementof these parts gives the gate a sufficient movement to permit the dropping of a cartridge through the opening at the proper time upon the shelf of the transverse feeder.
- crank-handle 88 Mounted loosely on the end of the shaft 49, outside of the case, is a crank-handle 88.
- Pins 89 (shown in the dotted lines in Fig. 4) project inwardly from the hub of the handle into slots 90, Fig. 5, in the outside face of the disk 91, that is secured to the end of the shaft.
- the pins projecting from its hub will engage the end walls of the slots in the disk secured to the shaft and turn the shaft, so as to cause it to draw back the breech-block.
- the handle When the breech-block is back, the handle may be turned from back to front without turning the shaft, the slots in the disk being long enough for this purpose and also long enough to allow the handle when in its forward position to remain stationary when the shaft turns from front to back as the gun operates.

SFEOIFICATION forming art er Letters Patent No. 636,977, dated November 14, 1899. Application filed May 24, 1899. Serial No. 718,063. (No model.)
To all whom, it may concern.-
Be it known that I, FRANK M. GARLAND, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Automatic Machine-Guns, of which the following is a specification.
This invention relates to an automatic machine-gun in which the barrel moves backwardly when a cartridge is fired and after compressing the operating-spring is drawn forward by the spring, while the breech-block moves farther backward for extracting the exploded shell and permitting the feeding of another cartridge into position for loading into the barrel, when the breech block is thrown forward, the breech-block being released for this purpose when the cartridge is properly fed.
The object of this invention is to simplify and make durable the mechanisms of such a gun, whereby the action will be positive and reliable.
The embodiment of the invention illustrated in the accompanying drawings has a barrel and a connected frame which move backwardly together and compress a spring when a cartridge is tired. The breech-block, bearing the spring firing-pin,first moves backwardly with the barrel-frame and then by means of intermediate mechanisms is moved farther back along the frame away from the breech as the barrel and frame are drawn forwardly. A spring is made tense by the backward movement of the breech-block, and a catch engages parts connected with the breech-block for holding it back against the force of the spring. The hammer, scar, and hammer-spring are borne by the frame, and the hammer is cocked by the movement of the breech-block away from the breech. The cartridges are allowed at the proper time to drop by gravity through the side of the case onto a transverse feeder that is held in place against the force of a spring by a latch that is released from a catch by the weight of the dropping cartridge. This feederswings transversely on a pivot and carries the cartridge into line with the barrel in front of the breechblock, and as the cartridge reaches the proper line a part of the feeder engages connections that release the breech-block catch and allow the block to be thrown forward and push the cartridge that has been fed in front into the breech of the barrel. As the breech-block reaches the forward limit of its movement the trigger engages a part connected with the finger-pull at the butt of the gun, which if drawn causes the trigger to disengage the sear from the hammer and allow the hammerspring to throw the hammer and drive forward the pin into the primer of the cartridge that has been loaded into the barrel. The backward movement of the breech block opens the passage, so that a following cartridge may be dropped upon the transverse feeder, and a part of the feeder closes the passage when a cartridge is being placed in front of the breech-blook. The forward movement of the breech-block forces back the feeder into position to receive the next cartridge.
Of the views, Figure 1 shows a plan of a gun that embodies the invention. Fig. 2 shows a side elevation, the end of the barrel being broken off and the mount being omitted. Fig. 3 shows an elevation looking at the butt of the gun. Fig. 4 shows a plan of the mechanisms on larger scale. Fig. 5 shows a side elevation of the mechanisms.

The case that incloses the mechanisms is octagonal in transverse section and is formed with a trunnion-band 1 and a butt-plate 2, between which extend ribs 3, Figs. 1 and 2. These ribs have undercut grooves, and slidingin the grooves are panels 4, Figs. 6 and 7.
Either or all of these panels may be slid out from the back, so as to permit ready access to the mechanisms contained in the case.
The trunnions 5 are held by boxes 6 at the upper end of the head-yoke '7, that is supported by any suitable mount 8. Held by ears 9, fastened to the underside of the case at the butt, is a nut 10. Through this nut extends a threaded sleeve 11, that is provided with a hand-wheel12 and a clamp-handle 13. A tube 14 extends from thehead of the mount through the sleeve 11. When the clampinghandle is loosened, the tube maybe slid freely through the sleeve, so as to permit the muzzle of the barrel to be elevated or depressed quickly. By turning the hand-wheel a fine elevation or depression may be obtained. At the end of the tube is a handle 15, and when this is loosened the gun and the head may be freely rotated upon the mount. Any desired sights 16 and 17 may be attached to the top of the casing, and a suitable shoulder-piece 18 may be fastened to the end. A hand-grip 19 is attached to the butt of the case, and this supports a finger-pull 20, Figs. 1, 2, and 3.
A pair of posts 21 are secured to the front endof the case,and at the outerends of these is a cross-head 22. The barrel 23 is loosely su pported by the front end of the case and the cross-head 22, Figs. 1 and 2.
An arm 24 is fastened to the barrel, and attached to the arm is a rod 25, that extends through the case, and in a cylinder 26 is fastened to a piston 27, Figs. 1, 2, 4 and 5. The cylinder 26, which is located in a chamber 28 in the upper front end of the case, is open at both ends to the fluid that fills the chamber. A- valve 29 is supported by the forward end of the case so as to be movable toward and from a passage 30 between the ends of the cylinder. This valve is thrust with a yielding pressure toward the passage 30 by a spring 31 and is limited in its movement toward the passage by the end of a rod 32, Fig. 4. This rod extends from the chamber to the butt of the gun, Where it may be connected with any suitable means for adjusting it lengthwise. Such means form the subject-matter of United States application for patent, Serial No. 714,389, filed by me on April 25, 1899, and are not herein described in detail. When the barrel recoils and the piston is forced back in the cylinder, the fluid in the chamber opens the valve against its spring and flows freely from the back to the front end of the cylinder; but the valve will shut as far as the end of the rod will permit and retard the flow of fluid in the opposite direction, and this reduces the speed of forward movement of the piston.
Fastened to the frame 33, attached to the breech of the barrel, is a rod 34, that on its front end is provided with a nut 35, Fig. 2. On this rod is a spring 36, one end of which thrusts against the nut 35 and the other end thrusts against a collar 37, connected with the upper end of a lever 38, Fig. 5. The thrust of this spring between the nut and collar forces the barrel forward, and the power of this thrust depends upon the position of the collar, which is changed along the rod by the lever as the elevation or depression of the muzzle of the barrel is altered. This mechanism forms the subject of United States application for patent,Serial No. 7l4,511,filed by me on April 26, 1899, and is therefore not herein described in detail.
Movable in a guideway 39 in the frame that is fastened to and is movable with the barrel is the breech-block 40. A recoil-block 41 is secured to the rear ends of the yoke 42, which is pivoted to the breech-block. breech-block is home, the yoke-arms hold the recoil-block in line with the axis of the barrel When the.
against the recoil-shoulder 43, Figs. 5 and 18.
The lower ends of the breech-block yokearms 44 are connected by a rod 45 with the lower ends of a yoke 46, that at its upper end is connected with the barrel-frame. The frame-yoke is connected near the middle of its length by links 47 with rocker-arms 48, that are secured on the tranverse shaft 49, the links 47 and the rocker-arms 48 forming a toggle connection between the shaftand the frame-yoke, Figs. 4, 5, and 8.
A spring 50 is wound upon the shaft 49 in such manner as to rotate the shaft in a direction that will throw the rocker-arms forward. One end of this spring is engaged with a stud 51, projecting from a part of the case, and the other end is engaged with a disk 52, that is adjustably connected with the shaft, so that the tension of the spring may be regulated, Figs. 4 and 7.
The force of explosion of a cartridge is transferred from the breechblock to the re coil-block and the frame, so that the frame and the connected barrel are driven backwardly. As these parts move backward together and the operating-spring is being compressed the frame-yoke moves backwardly without changing its relation to the other parts. When the parts are moving in this direction,'the links connected with the frameyokes cause the rocker-arms to rotate'upwardly and the toggle-joint to close to the position illustrated by the dotted lines in Fig. 8. One of these rocker-arms is provided with a shoulder 53, Fig. 8, and when the arm is up the shoulder is engaged and held by the upper end of a finger 54, projecting from a shaft 55, Figs. 4, 5, and 7. \Vith the rocker-arms held in this position the forward movement of the frame under the pull of the spring causes the frame-yoke to be oscillated to the position illustrated by the dotted lines in Fig. 8, and this change of relation of the parts causes the breech-block yoke to be oscillated, so that the recoil-block is freed from the recoil-shoulder, and then as the recoil-block moves backward ly in the openin gin the frame the breech-block is drawn away from the breech, so as to extract the exploded shell and open a passage for the feeding of a following cartridge, Fig. 8. The breech-block remains back until the rocker-arms are released and the spring upon the shaft throws the arms forward, which action causes the breech-block to be moved close to the breech of the barrel and the recoil-block to drop into position in front of the recoil-shoulder, Fig. 8.
The transverse feeder 56 is pivoted upon a stud 57, fastened to the front end of the case. This feeder has a ridge or shelf 58, that extends rearwardly beneath the opening 59 through the wall of the case, into which the cartridges drop from the feed-case, Figs. 6, 10, and 13. Extending above this shelf is a back 60, and projecting to one side from the back edge is a flange 61, that when the feeder is moved to feed a cartridge obstructs the passage and prevents the entrance of the following cartridge. The back and shelf of the feeder are shaped to properly support and carry the cartridges. A spring 62, wound about the stud, Fig. 5, tends to force the upper end of the feeder toward the center, so as to carry the cartridges into line with the breech-block and bore of the barrel.
The engagement of a wedge 63 on the edge of the breech-block with the edge of the shelf, Figs. 6, 10, and 13, when the breech-block moves forward forces the feeder to one side against the pressure of its spring into position to receive a cartridge.
The entire shelf 58 of the feeder upon which the cartridge is dropped may be hinged to the feeder, as illustrated in Figs. 13 and 14, or only a part 96 of the shelf may be hinged to the back 60, the part 97 being fixed to the back, as illustrated in Figs. 10, 11, and 12. If the entire shelf is hinged to the feeder, springs 64, Figs. 13 and 14, may be employed to hold the inner edge of the shelf raised so that the edge will engage with a catch-lug 65, that is secured to the front wall of the case, Figs. 6, 13, and 14. Then a cartridge drops upon this shelf, its weight is sufficient to depress the inner edge sufficiently for it to become disengaged from the lug, and then the feeder is thrown inward by its spring and the cartridge which it supports, and that accomplished the release is carried into line with the breech-block.
In the form shown in Figs. 10, 11, and 12 a hook 92 projects from the back of the movable part 96 of the shelf and is arranged to engage a catch 93, fastened to the case. The weight of a cartridge will depress the movable part 96 of this form of shelf against the thrust of the springs 66 and release the engagement of the catch and latch hooks. In the form shown in Figs. 15, 16, and 17 the latch-hook 94 is formed as part of a lever 67, pivoted to ears projecting from the feeder. The upper end 93 of the inner part of the lever extends slightly above the immovable fioor 99 of the shelf, so that it will be depressed by the weight of a cartridge for disengaging the hooks. In all of these forms the weight of a cartridge dropping upon the movable part of the shelf causes that part to be depressed, and this releases the latch, so that the feeder may be thrown forward to carry the cartridge into line with the breech-block.
Projecting from the lower end of the feeder is a finger 68, which is located and arranged to engage a finger 69 when the cartridge is in front of the breech-block and in line with the bore of the barrel, Figs. 6, 7, and 13. The
finger 69 projects from the shaft 55, that is provided with the finger 54, which engages the shoulder 53 for holding the rocker-arms and keeping back the breech-block when the barrel and frame are moving forward. The engagement of the finger 68 of the feeder with the finger 69 of the shaft 55 rocks that shaft, so that the finger 54 is withdrawn from the shoulder, and the rocker-arms are free to move forward under the impulse of the coiled spring 50 on the shaft 49 and throw the breechblock home, loading into the barrel the cartridge which has been placed in front by the movement of the feeder that released the breech-block parts.
The trigger-pull 20, supported by the handgrip 19, is connected by a rod 70 with a sleeve 71, placed upon the shaft 55. This sleeve is normally thrust forward by a spring 72, and to its forward end an arm 73 is fastened, Figs. 4 and 5.
The trigger 95, which is an angle-lever, is pivotally supported in an opening formed in the rod 45, that joins the breech-block yoke with the frame-yoke. A spring 74, placed in the opening, thrusts the lower end of this trigger forward, so that its upper rear end is held down. The scar 75 is carried in a mortise in the frame attached to the barrel, and a spring thrusts the rear end 101 of the sear toward the trigger and holds the front end 102 of the sear in position to engage the shoulder 103 on the edge of the hammer-block 76, which is pivoted in the same mortise. The upperend of the hammer extends between the arms of the yoke 42 into the path of the breech-block 40, and as the breech-block moves backwardly it forces back the hammer against the thrust of the hammer-spring 77 until the end 102 of the sear engages the shoulder 103 and holds the hammer cocked. When the lower end of the trigger is pulled backwardly, the upper rear end of the trigger will be lifted, so as to raise the end 101 of the sear, and this causes the other end 102 of the sear to be drawn down out of engagement with the shoulder 103, leaving the hammer free to be thrown for- IIO i seem? wardly by the spring 77 for striking the firingpin, Fig. 18.
The lower end of the trigger in its forward movement with the rod 45 will engage the arm 73 just after the breech-block reaches its forward position and is secured close against the breech of the barrel, if the trigger-pull is drawn back, and be held in such manner that the continued forward movement of the parts will cause the trigger to disengage the sear from the hammer, Fig. 1.8.
The hammer when thrown forward strikes the firing-pin 78, that is carried in a recess in the breech-block. This firing-pin is thrust forwardly by a spring 104. In longitudinal mortises in the upper and lower edges of the breech-book are extractor-bars 80, that have fingers 105 at their front ends for grasping the heads of the cartridges and drawing the shells out of the barrel when the breech-block moves backward and opens the breech. A lever 81 is pivoted in an opening in the breechblock, so that one end enters a slot 106 in the firing-pin and the other enters a slot 107 in the upper extractor-bar. A spring 79 in a recess in the breech-block forces back a plate 109,
and this by engagement with the hook ends 108 of the extractor-bars draws the extractorfingers back with a yielding pressure, so as to permit them to grasp the head of the cartridge. When the breech-block is at the backward limit of its movement, the rear ends of the extractor-bars engage with the recoilshoulder 43 and are forced forward against the thrust of the spring 79. This moves the extractor-fingers 105 away from the front face of the breech-block, so that the rim of a carfridge-head will surely pass between the fingers and the front of the breech-block. When the extractor-fingers are moved forward by the contact of the bars with the recoil-shoulder, the lever 81 draws back the firing-pin, so that its point will not interfere with the passage of the cartridge-head between the extractor fingers and the front wall of the breech-block.
After the cartridge-head is in position as the breech-block moves forward for passing it into the breech of the barrel the spring 79 draws back the extractor-bars, so that the fingers will grasp and hold the rim of the cartridge-head. The backward movement of the upper extractor-bar moves the lever 81, so that the firing-pin will be pressed forward by its spring 104 in position to be driven into a primer when the firing-pin is struck by the hammer.
Mounted upon the shaft 32, adjacent to the cartridge-feeding opening 59, is a gate 83. A spring 84, coiled about the shaft, holds the gate sufficiently in front of the opening to prevent cartridges from. dropping through onto the transverse feeder at an improper time. This gate has an arm 85, that by contact with a portion of the case limits the downward movement of the gate. A wedge 86 is formed on a part projecting from the lower portion of the gate, and this is arranged to be engaged by an inclined surface on a part 87, that projects from the breech-block when that block moves backwardly, Figs. 4, 6, 7, 10., and 13. The engagementof these parts gives the gate a sufficient movement to permit the dropping of a cartridge through the opening at the proper time upon the shelf of the transverse feeder.
Mounted loosely on the end of the shaft 49, outside of the case, is a crank-handle 88. Pins 89 (shown in the dotted lines in Fig. 4) project inwardly from the hub of the handle into slots 90, Fig. 5, in the outside face of the disk 91, that is secured to the end of the shaft. When the handle is turned from front to rear, the pins projecting from its hub will engage the end walls of the slots in the disk secured to the shaft and turn the shaft, so as to cause it to draw back the breech-block. When the breech-block is back, the handle may be turned from back to front without turning the shaft, the slots in the disk being long enough for this purpose and also long enough to allow the handle when in its forward position to remain stationary when the shaft turns from front to back as the gun operates.
