To cir/ZZ whom it ina/y concern:

Be it known that I, JOSEPH H. WEssoN, a citizen of the United States of America, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Magazine-Pistols, in which the following is a specification.

This invention relates to magazine-pistols of the sliding-barrel type, the object of the invention being to provide an arm of this character in which the magazine is located in the handle or grip of the arm vand the barrel is drawn rearwardly toward the recoil-plate across the upper end of the magazine to engage the uppermost cartridge in the latter, carrying the same to the rear against the recoil-plate, the engagement of the barrel with the cartridge inserting` the latter in the barrel and the rearward movement serving tocock the arm, which may then be fired by a pull on the trigger in the usual manner. This-construction is practically the reverse of the usual action of arms of this type, so far as I am aware, these having generally been so constructed that the pull on the trigger will -first carry the barrel forward against the compression of a spring, which when the barrel is released moves thelatter rearwardly to pick up a cartridge and fire it by carrying it back against a fixed bearing-pin.

My prior reissued patent of January 9, 1900, No. 11,800, is a good example of the type referred to, and the diHerence between that type and the one forming the subjectmatter of this application is radical in that in this case the barrel is pulled back by the second finger to eect the loading and cocking of the arm, leaving the Erst linger free to `pull the trigger, thus making itv possible to do far more accurate shooting than isy possible with the old type,.in which the triggerfinger is under constant strain until the arm is fired. i

In the present construction when the barrel isretracted-it is moved against the tension of a barrel-'springend of a mainspring which are entirely separate, and associated with the trigger is a safety device whereby the barrel is locked in its most rearward position prior to the release of the firing mechanism.

Referring now to the drawings, Figure 1 is a sidev elevation of apistol in which the invention has been embodied, one of the cheekpieces of the grip being removed. Fig. 2

, only being shown.

shows this cheek-piece in perspective. Fig. 3 is a top planview of the rrear end of the arm, a portion of the frame being broken away. Fig. 4 is a vertical section in the plane of line 4 4, Fig. 1. Figs. 5 and 6 are vertical sections in the planes of lines 5 5` and 6 6, Fig. 1. Fig. 7 is a longitudinal section through the frameof the arm centrally. Fig. 8 is a longitudinal section through the barrel,l showing the relation of the latter tothe barrel-lug. Fig. 9 is a vertical section in the plane of line 9 9, Fig. 8, looking toward the rear end of the barrel. Fig. 10is aperspective view of the upper end of the magazine-case, showing the relation of a cartridge thereto and showing the relation of the rear end of the barrel to the cartridge, a portion of the barrel Fig. 11 is a longitudinal sectional elevation of the frame, showing the other parts in full lines except for a portion of the barrel and a portion of the firing mechanism which are broken away, the barrel being shown in its most forward position. Fig. 12 is a similar view showing the barrelv retracted in firing position, the trigger also being retracted in the barrel-lock being shown in operative position and the sear released from the ring mechanism, all the parts being in the position they will occupy at the moment just preceding the discharge. Fig. 13 is an enlarged view of the upper end ofthe magazine in -end elevation, partly in section and in side elevation, showing the position of the retaining-spring for the cartridges inthe wall of the magazine.

Referring to the drawings, the handle or grip portion of the arm in which the magazine is located is indicated by a, the frame portion at the upper end of the handle by b, and the barrel-receiving portion by c, this latter portion of the framebeing longitudinally slotted along the under side thereof, as indicated by d,-to receive the'barrel-lug, in

which is located a part of the barrel-operat' ing mechanism and firing mechanism, as hereinafter described, the above-referred-to parts of the frame constituting, preferably, an integral construction; but for the sake of clearness of description the parts will generally be referred to in the following specilicationvas above designated. Referring'to Figs. 1, 4, 7, 11, and 12, these will disclose very clearly the construction of this integral frame of the arm, the description of which. willl be made in the course of the specification.

The barrel e is cylindrical and preferably IOO IIO

of uniform diameter, and depending therefrom is a longitudinally-disposed lug f, preferably integral with the barrel and, as shown in the sectional views, having a width equal to the diameter of the barrel. As shown in Figs. 8 and 9 principally, this lug has a recess or slot p milled therein from one end to the other longitudinally thereof, the width of which is shown in said Fig. 9, and it is in this slot that the trigger and some of its associated parts are located, as reference to the general views 11 and 12 will show. The lug f is separated from the barrel, as shown in Fig. 8, for a certain distance extending inwardly from the rear end thereof for a purpose hereinafter described. The lug has a sliding fit in the longitudinally-disposed recess d in the frame, and the barrel is supported in the chambered portion c of the frame by means of the bearing-plate g, secured to the forward end of the latter, which. plate is secured to the frame by screws 7L h and has a'central opening therethrough for the barrell",

The chambered portion c of the frame in which the barrel is located is bored out to a larger diameter than that of the barrel as far back as the point j, from which the bore extending through the remaining portion of the'frame is of the same diameter, and in this the rear end of the barrel is supported. It is therefore clear that by the sliding iit of the lugf with the recess d the barrel is nonrotatably supported in its frame and may slide in the latter backward and forward in a straight line.

The barrel-supporting part of the frame,

y bored out, as above described, as far back as the point j, provides an annular chamber in which is located the spring 7c, which. encircles the barrel and which is the mainspring of the arm, collars m and o being located in this annular chamber and loosely encircling the barrel, the position of these collars being shown in Figs. 1, 11, and 12. The spring k bears vagainst the rear end of this chamber at y' and'against the collar m, which is the active member of the firing mechanism.

The longitudinal slot p, above referred to, which extends from end to end of the lug f, has located therein certain operative parts of the mechanism, as follows: A hole gis bored in the frame, a similar hole 1' being drilled in the vend of the lug f before the latter is slotted, these two holes being in axial alinement, and in these two holes is located a coiled spring s, which. is the barrel-actuating spring. Forwardly of this point a trig' ger t is pivotally supported in said slot on a pin/u., vand forwardly of the trigger is a T- shaped barrel-locking lever o', supported to swing on the pin w in the plane of the trigger and toward and from the barrel. In proximity to the trigger the sear x is pivotally supported on the pin y to engage a circumferential groove m, turned in the collar m, the sear being released from its engagement therewith by a pull on the trigger in the usual manner. A trigger-guard is secured in the lower part of said slot p in the lug f, said guard being provided at the lower rear end thereof with a forwardly-curved member 2 to be grasped by the second finger of 'I the hand, whereby the barrel may be retracted and the arm cocked, leaving the foreiinger free to pull the trigger. When the barrel is thus retracted, the loading is effected, as will be described further on, and if it is not desired to iire the arm the release of the pressure on the member 2 of the guard will permit the barrel to be moved forward again to the position shown in Fig. 11, said forward movement being eifected by the spring s, which is compressed, as shown in Fig. 12, by the retraction of the-barrel; but if the arm is to be fired pressure on the trigger will act first to lock the barrel in its retracted position prior to the actuation of the sear as follows: The forwardv lower portion of the frame is provided with two oppositelylocated L-shaped grooves 4, (shown in Figs. 5, 7, and 12,) into which the ends 5 of the cross-head on the forward end of the barrel stop lever o extend, a spring 6 being located between said lever and the barrel to normally hold the lever in the position shown in ,22, forcing the forward end upwardly, the

ends 5 of the cross-head entering the up wardly-extending portions ofthe grooves 4, thus locating these ends 5 transversely of and in close contact with the end of the barrel-lug f, as shown in Fig. 12. A furthermovement of the trigger will then bring the projection 26 thereon against the end of the sear releasing the latter from the collar m, which. will then be shot forward against the collar 0, which. is loose on the barrel. This collar is connected by straps or rods 21, which extend longitudinally of the barrel, on each side thereof, back through the rear end of the frame and inline with the axis of the y barrel, to a block 22, having a firing-pin 23 therein, the rear end of the upper portion of the frame being milled out to permit the free play of the block I 22 therein toward and from the base of the cartridge. This rear upper end of the frame is indicated by b, and the forward vertical wall thereof constitutes the recoil-plate 19 for the cartridge 10. The straps 21 are located in grooves 24, formed in opposite sides of the chambered-out portion of the frame, preferably as shown in Figs. 4 and 7. As the barrel is retracted it moves across the top of a magazine located in the handle and picking up the uppermost cartridge therein carries it back against the recoil-plate 19. As stated, the magazine is located in th IOO handle of the arm, a rectangular chamber 8 being provided in the latter for its reception, the opposite side walls of this opening being formed by the cheek-pieces 25 of the handle. In this chamber is a rectangular magazinecase 9, which in its general construction is the same as described in my aforesaid reissued patent of January 9, 1900, No. 11,800, the cartridges 10 being inserted in the magazine through the upper end thereof and located therein one above the other, as described in my said patent, there being a spring 12 in the lower end of the case to feed the cartridges upward. The cartridge-case is held in place in the handle by means of two springs 15, having the buttons 14 thereon, the springs being provided with hooks to engage lips in the frame, as shown in Fig. 4. By pressing on these buttons 14 the spring-hooks may be `disengaged from the handle and the case drawn out. As described in my said prior patent, the cartridges 10, as shown in the various figures of the drawings, are provided with a strong reinforcing-ring 18, which is fitted over the shells proper, the latter being indicated by 10a. The forward ends of the shell extend beyond the end of the reinforcing-ring far enough to permit the entrance of the end of the cartridge into the barrel, said reinforcingring constituting practically a continuation of the barrel when the latter is in firing position, as shown in Figs. 1, 3, and 12.

To bring the cartridge into axial alinement with the barrel, the upper ends of the magazine-case 9 are curved inward, as shown particularly in Fig. 10, to constitute the lips 17, which overlap the reinforcing-ring of the cartridge and constitute a stop againstwhich the uppermost cartridge is forced by the magazine-spring 12. The lips 17, however, do not extend across the entire end of the case, but toward the rear side of the case are cut away to such an extent that when the barrel-pushes the top cartridge back to the position shown in Fig. 12 the reinforcingring on the cartridge will be moved out from under these lips, as shown in this figure, and thus be in position to be ejected as soon as the barrel moves forward, leaving the empty cartridge-case in the position in which it was fired, attention being called to the fact that while in this position it is still located in the path of movement of the cartridges in the magazine, and therefore when freed from the barrel it will be ejected by the upward movement of'the cartridges in the magazine, the uppermost one of the latter'being caught by the lips 17' at the top of the case 9 in position to be engaged by the next retracting movement of the barrel and carried rearwardly againstA the recoil-plate 19. 'The arm having been fired, a release of the pressure on the trigger will permit the spring 6 to throw the locking-lever v downward to the position shown in Fig. 11, whereupon the release of pressure upon the member 2 of the guard will permit the spring s to throw the barrel forward, and this movement will carry the sear (whose rear end is normally pressed upward by the spring 3) into engagement again with the groove m of the collar m, `thus bringing the parts into position-again for another shot.

From the foregoing description it is apparent that in its general features the magazine is like that vdescribed in my said prior patent. In two points, however, it differs therefromviz., in the provision of the lips 17 to arrest the upward movement of the cartridges and in the provision of the springs 17 a, (shown in Fig. 13 most clearly,) whereby the uppermost cartridge may be held against endwise movement except when pushed out of the magazine by the rearward movement of the barrel. These springs are set in grooves in the opposite side walls of the magazine, and their free upper ends snap into grooves 17b in the reinforcing-ring on the cartridge, the shape of which is such as to allow the cartridge to move toward the recoil-plate only, and when it is in position thereagainst these vfree ends of the springswill snap inward against the shell in front of the yreinforcingring on the cartridge, and thus prevent the latter from being drawnforwardby the for- 1 ward movement of the barrel should the shell perchance stick in -the barrel. A shallow notch 17c inthe end of the barrel, Fig. 11, provides space for the end of the spring17a between thefbarrel and the reinforcing-ring on the cartridge when these parts are in contact. In operation,therefore,the barrel, the trigger, and the collar m, engaged by the sear, and the locking-lever v are all moved rearwardly by a pull on the member z of the trigger-guard or equivalent member. `This compresses the mainspring 7c and the barrelspring s. Whenthe barrell comesvto a stop by the contact of the end of the cartridge with the recoil-plate and the trigger is pulled by the forefinger, the lever v is thrown into locking engagementV with the fore-end of the lug on the barrel, and a subsequent movement of the trigger in the same direction disengages the sear from the collar m, which is shot forward by its spring 7c against the collar o, which through the straps 21 will carry the firing-pin 23 against the primer in the cartridge. Pressure on the trigger and its guard is now released, and the locking-lever is disengaged from the lug f and vertical portions of the grooves 4 in the sides of the frame, and the barrel-spring s will 'carry the barrel forward, the sear Qc passing under` the collar m and engaging the groove fm therein. As soon as the barrel is separated from the cartridge the spring 12 in the magazine pushes the line of cartridges therein upward, ej ecting the empty shell and locating a loaded one under the lips 17 in position to be picked up by the next rearward movement of the barrel.

Attention is called to the fact that the collar o is loose on the barrel, and when the collar 'm strikes it is driven forward until it comes in contact with the lug f, Where the latter oins the barrel, and when a new cartridge is carried back against the recoil-plate mit will strike the end of the firing-pin, which will then project through said plate and push it back into the plate, thus moving the collar o back to the position shown in Fig. 12.
