SPECIFICATION forming part of Letters Patent No. 437,574, dated September 30, 1890.

l Application led December 12, 1889. Serial No. 333,462. (No model.)

To a/ZZ whom it may concern.-

Be it known that I, LEIGHLIN CONROY, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Magazine Fire-Arms, of which the following is a specification.

My invention relates to certain ne7 and useful improvements in magazine fire-arms, known as bolt-guns, or arms wherein a reciprocating breech-block provided with an extractor and firing-piu is used, and I have pointed out said improvements in the following specification and claims and illustrated the same in the accompanying drawings, in which- Figure l represents a longitudinal sect-ion, showing the rear portion of the gun with the parts in position after a cartridge has been fired, the empty shell being still in the barrel. Fig. 2 is an addition to Fig. 1, showing the front end of the gun when the feed-slide is in the forward position. Fig. 3 is a transverse section in the plane Fig. l. Fig. 4 is a longitudinal section showing the bolt partially drawn back.V Fig. 5 is a transverse section in the'plane x', Fig. 4. Fig. 6 is a plan or top -view of the feed-slide and follower detached. Fig. 7 is a similar view to Fig. 4 when the bolt has been drawn back completely, on a larger scale than the previous figures. Fig. 8 is a similar view to Fig. 2 when the feedslide is drawn back. Fig. 9 is a transverse Section inthe plane y y, Fig. 8. Fig. 10 is a horizontal section in the plane z z, Fig. 7. Fig. 11 is a vertical section in the plane z z', Fig. 10, the bolt having been removed to expose the parts below. Fig. 12 is a transverse section in the plane z2 z2, Fig. 10. Fig. 13 is a longitudinal central section of the rear portion of the gun when the same is adjusted for a single-loader. Fig. 14 is a transverse section in the plane x2 m2, Fig. 13. Fig. 15 is a plan or top view of the carrier detached. Fig.`16 is a transverse section in the plane 0632123, Fig. 15. Fig. 17 is a plan view of the locking-sleeve carrried by thebolt. Fig. 1S is a detached elevation of the feed-pawl and the stop-pawl.

In the drawings, the letter A designates the barrel, which is secured in the receiver A.

B is t-he bolt, and C is the magazine, which is situated beneath the barrel, and into which fresh cartridges may be introduced through the breech of the gun when the boltis drawn back.

The cartridges are fed toward the breech by means of a follower D, which is actuated by the feedslide E, as will be presently eX- plained. The follower' is composed of two heads a a, which are connected by two plates b b. plates are situated two pawls c d, which swing on a common pivot co, the pawl c being the feed-pawl and the pawl d the stop-pawl. From the hub of the feed-pawl c extends a tail c into a groove c2 in the bore C', to which the magazine C is secured.

In the bottom part of themagazine is firmly secured a rack-bar d', which is provided with ratchet-teeth cl2, Fig. 6, the distance between which is equal to the length of the cartridges, and which are in position for engagement with the stop-pawl d.

The feed-slide E extends on the side of the fixed rack-bar d andis provided with ratchetteeth c3, the distance between which is equal to that between the teeth d2 of the rack-bar d', and which are in position for engagement with the feed-pawl c.

The stop-pawl d is provided with a slot d3, Figs. 8 and 18, and the feed-pawl c is provided with a pin d4, which engages the slot d3, so that when this feed-pawl is raised a sufficient distance the stop-pawl :is thrown out of engagement with the rack-bar d', and when the feed-pawl is depressed it carries the stop-pawl along. The pin d4, however, has sufficient play in the slot d3, so that when the feed-bar E is moved forward and the feed-pawl is raised thereby the stop-pawl is not thrown outot engagement with the stationary rack-bar d', and the stop-pawl will only be thrown out of engagement with the stationary rack-bar when the magazine has been exhausted, as will be presently explained. Both pawls are exposed to the action of spring-actuated stops d5 d, respectively, which extend into notches in the hubs of the pawls and serve to retain said pawls with a force commensurate to their springs when the pawls 'are down and when they are up.,

The feed-slide E receives a reciprocating motion by means of a dog F, pivoted to the (See Figs. 6 and 9.) Between these IOO 2 Y' 4mm upon the carrier L, while the projection f of the dog F strikes the ridge G, sovthat the said dog is thrown out of gear with the feed-slide E, Figs. 4 and 7 The carrierL is trough-shaped, Figs. and 16, and it swings on pivots l. When the bolt B is moved from the position shown in Fig. 4 to that shown in Fig. 7, the

projection H strikes the tail of the carrier, and

the front portion of said carrier, which carries a cartridge, is raised to the position shown in Fig. 7,l and the cartridge is ready to be pushed into the barrel by the subsequent forward movement of the bolt.

The carrierL is locked in its raised position by a spring-catch I, Fig. 7, which is situated beneath the barrel, and when the bolt is moved forward, so as to close the breech, this spring-catch is pushed back to the position shown in Fig. 1, and the carrier L being released returns to its original position, while the follower D remains stationary, being held in position by the stop-pawl d. As the bolt is moved forward, the feed-slide is pushed forward in the magazine, and when the bolt is again drawn back the next cartridge is 4pushed upon the carrier. When the magazine has been exhausted, the tail c of the feedpawl strikes the shoulder c7 at the inner end ot the groove c2, and both pawls c d are raised and retained in this position by the springstops d5 d6, Fig. 4,-so that by bringing the gun in an inclined position the follower D can be made to slide tothe forward end of the magazine and fresh cartridges can be introduced. When the follower reaches the forward end of the magazine, the tail c strikes the shoulder ce, Fig. 2, and both pawls are returned to their workin g positions. A stop e9 limits the backward movement of the tail c.

When the feed-slide Eis in its forward position, Fig. 1,` the dog F, which engages the recess e0 in the rear portion of the feed-slide, is in position to be thrown out of engagement with the feed-slide bythe act-ion of a lever J, which has its fulcrum onapivot j, and the tail end of which engages a recess j@ in the hub of a finger-lever K, which has its fulcrum on a lpivot k. If the finger-lever is moved in the reverse direction indicated by the arrow shown near it in Fig. 1, the lever J throws the dog F out of engagement with the feed-slide, and the tail end of the lever K acts upon the carrier vL 'and moves the same up into the breech and retains it in the position which said carrier occupies in Fig. 13. The bolt B can now be moved backward and forward without actuating the feed-slide, andthe gun can be used as a single-loader.

On the rear end of the bolt Bis fitted a sleeve M, from which extends a handle N, and which is retained in position by a screw-cap O. (See Figs. 1 and 4.) On the body of the sleeve M is cut a screw-thread, portions of which are cut away, so as to form a series of threaded segments m m2 m4, which alternate with the plain segments fm m3 m5, Figs. 3, 5, and 17. On the rear end of the receiver A is cut a screw-thread to engage the screw-thread on the sleeve M, and this screw-thread in the receiver is formed into plain segments and threaded segments corresponding to the segments m m fmz'mmf m5 on the sleeve, but disposed in such a manner that when the handle Q N of the sleeve occupies a vertical position the threaded segments m m2 m4 stand oppositethe plain segments in the receiver, and if the bolt B is pushed forward to the position shown in Fig. l the threaded segments m m2 m4 of the sleeve enter the corresponding plain segments in the receiver. Vhen the handle N is then turned to the position shown in Fig. 1, the threaded segments m m2 m4 of the sleeve lengage the adjoining threaded segments in the receiver, and the front end of the bolt is firmly presssed up against the rear end of the barrel and held there while the gun is fired. By these means the bolt can be firmly locked without turning the same, and when the bolt is locked the handle N does not obstruct the sight.

On the bolt are secured the extractors P. (See Figs. 7, 10, 1l, and 12.) They are fitted into recesses p in the body of the bolt and held in position by scrcwsp, which extend through slots p2 in the Shanks of the extractors, so that said extractors can slide a short distance in the direction of their length When the carrier L, together with the cartridge, is raised to the position shown in Fig. 7, the rim of the cartridge is forced between the extractor, (see Fig. 10,) so that the hooks p3 of said cartridges are in front of the rim of the cartridge. If the bolt is now pushed forward so as to close the breech, the hooks p3 of the extractors enter the recesses p4 in the rear end of the barrel, Fig. 7, and when the gun has been fired and the bolt is moved back the hooks p3 carry the empty shell of the cartridge back into the breech, whence it can be readily removed.

From this description it will be seen that the rims of the cartridges are thrown in engagement with the extractors by thev action of the carrier, and it is onlynecessary to move the extractors far enough out beyond the end of the bolt, Figs. 7 and 10, so that if a cartridge is raised up by the carrier the rim of said cartridge will occupy a position behind the noses of the extractors. Vhen the bolt is pushed forward, the cartridge is driven into the rear end of the barrel and the extractors enter the recesses p4, and as their front ends strike the ends of these recesses they (the ex- ICO IIO

tractors) slide back, and the cartridge is retained in close contact with the front of the bolt, Fig. 1. The extractors do not spring over the rims of the cartridges, and the recesses p4 are'made just deep enough to be filled up completely by the front ends of the extractors, leaving no ventage when the cartridge is iired. If the bolt is moved back the extractors remain stationary for a short time, and by the time the screws p strike the rear ends of the slots p2, Fig. 10, the bolthas acquired sufficient momentum to cause the eX- tractors to throw the cartridge out with the required velocity.

What I claim as new, and desire to secure by Letters Patent, is- Y 1. In a magazine ire-arm,the combination, with the barrel A, the receiver A', and the bolt B, of the magazine C beneath the barrel, the feed-slide E, provided with ratchet-teeth, the rack-bar d', fixed in the magazine, the follower D, the pawls c d, mounted in the follower, and the dog F, carried by the bolt and constructed to engage the feed-slide, substantially as described.

2. The combination, with the barrel A, the

receiver A', the bolt B, and the magazine C, of the feed-slide E, the dogF, carried by the bolt and constructed to engage the feed-slide, the projection G to throw the dog F out of gear with the feed-slide, the carrier L, and the projection Il on the bolt for actuating the carrier, substantially as described.

3. The combination, with the barrel A, the receiver A the bolt B, and the magazine C, of the carrier L, the projection H on the bolt, and the latch I in the front part of the receiver, substantially as described.

4. The combination, with the barrel A, the receiver A', the bolt B, and the magazine C, of the feed-slide E, the dog F, carried by the bolt and constructed to engage the feed-slide, the leverJ,for throwing the dog F out of gear with the feed-slide, the iinger-lever K, and the carrier L, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subseribin g witnesses.

LEIGHLIN CONROY.
