MAGAZINE-GUN.

SPECIFICATION forming part of Letters Patent No. 435,905, dated September 2, 1890.

Application led November 19, 1889. Serial No. 330,865. (No model.)

.To all whom it may concern.:

Be it known that I, SIMON B. SHAFEER, of Ekalaka, in the county of Custer and State of Montana, have invented a new and Improved Magazine-Gun, of which the following is a full, clear, and exact description.

This invention relates to magazine-guns of the type wherein a horizontally-sliding breech bolt or block is operated by a lever that swings downward beneath the frame, and wherein a tubular magazine located beneath the barrel is employed, the main objectsof the invention being to iirmly lock the breech bolt or block in position at the time of firing, to obvia-te the throwing of the breech block or bolt to the rear of the hammer when the breech is opened, and to improve the extractor mechanism.

The invention will first be described, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar iigures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a longitudinal sectional view of myimproved magazi1'1e-arm,the view being` taken just inside of the right-hand plate ofthe frame, and the parts being represented as they appear when in the iiring position. Fig. 2 is a sectional plan view on line 2 2 of Fig. 1. Fig. 3 is an inverted plan view of the carrier-block and its attachments. Fig. 4 is a cross-sectional View of the carrier-block. Fig. 5 is a plan view of the combined extractor and ejector-spring. Fig. 6 is a central longitudinal sectional view of the arm, the parts being represented as they appear when the breech is open. Fig. 7 is a cross-sectional view on line 7 7 of Fig. 6. Fig. 8 is a crosssectional view on line 8-8 of Fig. 6; and Fig. 9 is a detail view of the forward end of the forward section of the breech block or bolt. In the drawings above referred to, 10 represents the lock case or frame, the side plates of which case or frame are formed with horizontal grooves a and with vertical grooves b and c. The horizontal grooves ct are entered by anges 11, that extend laterally from the side faces of the breech -block proper 12. VVit-hin the breech-block 12 I arrange the forward firing-pin section 13, such firing-pin section being normally held retracted by a spring 14, the action of the spring, however, being controlled by a stop or limit pin 15, carried by the breech-block 12, the pin 15 riding in a slot d, that is formed in the firing-pin. The upper face of the block 12 is recessed to rcceive the body of a spring-extractor 16, such extractor being formed with a hook e, while the lower face of the block is recessed to receive an extractor 16, formed with a hook e', such hook being normally held in a position to engage a cartridge-rim by the arm f of a spring 17, the other arm f of such spring engaging a heel g, that extends to the rear from an ejector 18, such ejector being pivotally mounted at 7L and being normally held within a recess il by the armf of the spring 17. The extractor 16 extends overa lateral projection 7c, carried by an arm 7c', that extends forward fromthepivotal support of the ejector, the arrangement Vbeing such that if the forward end of the extractor 16n be thrown downward the ejector will be moved to the position in which it is shown in Fig. 6 and the forward end of the empty shell tilted upward.

To bring about the desired movement of the forward end of the extractor 16, I form such extractor with a rearwardly-extending arm having an inclined face Z, which, when the block 12 is moved to the rear, will bear against a shoulder Z', formed upon the hammer 20, said hammer being mounted upon a pivot-pin 21 and connect-ed to the mainspring..r 22 by a link 23.

To the rear of the block 1 2 I mount a locking-block 30, which has side flanges b and c', such flanges riding in the grooves c and b. The block 30 is bored to receive the rear ring-pin section 31, which section is normally held retracted, as represented in Fig. 6, by a spring 32, the throw of the spring being limited by a stop 15a, that is carried by the block and rides in a slot- CZ formed in the firing-pin.

In order that the

blocks

12 and 30 may be reciprocated within their ways, I provide an operating-lever 50, that is pivotally mounted at p, and this lever I form with a spur or arm 51, which has lateral projections 52, which said projections, when the parts are in the IOO position in which they are shown in Fig. 1, rest above the short arms q of a lever 53, the long arms q of such lever being connected tothe block 30 bya link 54. v The lever 50 is also provided with a forwardly-extending arm 55, which has a Iiat head 56, which,when the parts are in the position shown in Fig. 1, rests somewhatbelow the lower surface of the block 12 and directly beneath a recess 0^ formed in said block.

From the construction above described it will be seen that when the lever is thrown, as indicated by its arrow, (see Fig. 1,) the initial movement of the lever 50 will carry the lever 53, as indicated, and as the lever 53 somoves the block 30 will be carried downward to the position in which it is shown in Fig. 6-that is, to a position below the block l2. The above-described movement of the lever 53 will carry the arms q to a position such that the lever projections 52 will clear said arms, and just as the lever projections 52 clear the arms q the head 56 of the arm 55 will be brought to bear against the rear,

defining-wall of the recess fr, and any continued movement of the lever 50 will carry the block l2 to the rear, and eventually to the position in which the parts are shown in Fig. 6, this rearward movement of the block 12 forcing the hammer 2O backward to its cocked or ring position.

In order that the cartridges may be transferred from the tubular magazine 57 to the cartridge-receiving chamber of the barrel 58, I provide a carrier-bloek 60, which has pivotally-mounted side wings 6l, that are normally held, as represented in Fig. 8, by springs 63, which bear upon projections 66, that eX- tend inward from the wings. The carrierblock is pivotally connected to a link 64, that is also pivotally connected tothe arm 55 of the lever 50, the link 64 extending forward from its pivotal connection with the arm beneath a shoulder u, that is formed on the arm.

In order that the wings 61 may be moved to the position in which they are shown in Fig. 4-that is, to a position to permit of the passage of a cartridge-rim -I provideatongue 62, that is pivotally connected to the block and arranged to bear upon the wing projections 66, the rear end of this tongue 62 being slotted, as shown at u', (see Fig. 6,) to engage a pin c, carried by the link 64, the arrangement being such that if the forward end of the cartridge-carrier be raised the forward .end of the tongue 62 will be carried upward and will throw the wings 61 outward against the tension of their springs ,63. This is the position the parts assume whenever the lever 50 is thrown upward, as represented in Fig. 1, the forward portion of the carrier-block 60 at this time riding up upon an inclined surface w and the rear portion of the carrier block being held down by the action of the shoulder u upon the link 64.

In the inner face of one of the side plates I form grooves 0 o s s', such grooves being adapted to receive a projection 67, that extends laterally from thecarrier, the arrangement being such that as the lever 50 is thrown downward the carrier will be drawn to the rear, its projection 67 at this time riding in the groove o; but just as the projection 67 reaches the rear end of the groove o beneath the groove o the arm 55 of the lever 50 will bear upon a projection 68, that is carried by the short armt of a lever 70, said lever 70 being pivotally mounted to the left of the lever 50, and any continued movement of the lever 50 will rock the lever 70 in a manner such that its long arm t will be raised to bear against the link 64:, and thereby raise the forward end of the link, and with it the carrier, thus moving the carrier to a position such that when the motion of the lever 50 is reversed the cartridge held by the carrier will be borne upon by the forward end of the block 12 and forced forward into the firingchamber of the barrel, the projection 67 at this time traveling forward in the groove or way s, finally arriving at the position in which the parts are shown in Fig. 1.

Although not positively essential, I prefer to provide a switch 71, that is arranged as shown in Fig. 6, and although any proper attachment might be employed to retain the cartridge within the magazine,I prefer t0 employ a spring-catch 72, which catch is depressed when the carrier is moved downward to a position proper to receive a cartridge from the magazine.

One great advantage of the construction above described is that it is impossible to eX- plode a cartridge until the breech and locking blocks are in firing position and the breech-block firmly locked to place, whereby the danger of the blowing of the breech-block to the rear by a premature explosion is avoided.

In referring to horizontal and vertical movements in the above description and in the following claims I desire it to be understood that when such terms are employed the gun is supposed to be in the iii-ing position.
