FIREARIVI.

To @ZZ whom z' may concern Be it known that we, GEORGE XV. Prox, Jr., and TILL-ARD M. Fsnnow, Sr., citizens of the United States of America, and residents of the city of lVashington, in the DistrictI of Columbia, have invented certain new and useful Improvements in Firearms, of which the following is a specification.

This invention relates to a certain new and useful improvement in breech loading fire arms of that class in which the barrel is mounted to be moved laterally or sidewise, and it has for its objects among others to provide a simplified and improved construction of fire arm of this general nature in which the sidewise movement or opening is automatic, being cont-rolled by fastening means located outside of the barrel in convenient position for ready manipulation, the construction being such that when this outside fastening device for the barrel is actuated, the barrel is opened automatically by means of a spring which is concealed between the barrel and stock.

XVe provide an extracting device controlled by the opening and closing of the barrel for the purpose of extracting the exploded shell and reloading the chamber with a fresh cartridge. This extracting mechanism is of such a nature that it allows the chamber in the barrel to be opened beyond the standing breech before starting the exploded shell for extraction and then by an eccentrically operated mechanism quickly pushes the shell from the chamber.

te aim further at improvements in the details of construct-ion whereby better results are attained, the various parts made capable of manufacture at minimum cost, are capable of ready assemblage, not liable to get out of order or become damaged in any way and constituting in their entirety a compact mechanism for the accomplishment of the ends in view.

Other objects and advantages of the invention will# hereinafter appear and the novel features thereof will be particularly pointed out in the appended claims.

The invention is capable of embodiment in a variety of forms, the preferred ones only of which are herein illustrated. The invention, in such preferred forms, is clearly illustrated in the accompanying drawings, which, with the numerals of reference Specication of Letters Patent.

Fig. 9 is a detail in bottom plan, showing the extractor mechanism in one position. Fig. 10 is a similar view showing the same parts in the position they assume after the shell has been extracted.

Like numerals of reference indicate like parts throughout the different views.

Referring to the drawings, l designates the barrel, 2 the stock, 3 the trigger and 4f the hammer of known construction except as hereinafter specified. 5 is a. front sight and G a rear sight which also may be of any of the well known or approved forms of construction to which no claim is made herein.

7e will first describe the novel features of the stock, the upper face of which is clearly shown in Fig. 4, a barrel having been entirely removed. This upper face of the stock is provided with the slot '7 extending substantially centrally and lengthwise of the stock, terminating at its rear end in the circular enlargement 8 constituting in effect a key-hole slot. To the rear of this and extending rearward and toward the left hand edge of the stock is an inclined slot 9, the purpose of which will soon be described. Forward of the key-hole slot 7 8 is a centrally disposed opening l0 for the reception of the shank 1l of a thumb screw, the milled head l2 of which is disposed upon the under side of the stock, as seen clearly in Figs. l and 3, being preferably partially, at least, seated within a correspondingly shaped. recess or socket 13 on the under side of the stock.

In advance or forward of the opening 10 and between the same and the right hand end of the stock, there is a substantially longitudinally extending curved slot 14- as is best illustrated in Fig. et. The hey-hole slot 7 8 is of considerable depth, as seen in Fig. 3, for a purpose which will soon be made clear.

The mechanism constituting the essential features of the present invention, aside from the barrel fastening device, is ent-irely concealed and disposed between the adjacent faces of the stock and barrel, as will be clearly understood upon reference to Figs. d and 5 and Fig. 3, in the latter view these parts being shown in their relative positions. In said Figs. at and 5, the parts are shown in face view, it being understood that when assembled, the face portions seen in these views are placed face to face or adjacent each other.

The under face of the barrel is provided with a chamber or depression 15, seen best in Fig. 5, within which is disposed a spring 1G, in the present instance shown as substantially V-shaped, the end of one of the legs or terminals thereof being` bent at substantially a right angle, as seen at 17, said bent or angular end being designed to be engaged in the curved slot 14, as seen in Fig. 3. Adjacent the rear end of this chamber or depression 15, the under face of the barrel is provided with a substantiallyT transversely disposed arcuate slot V18 which receives the inner end of the shank of the thumb screw 11, as seen in Fig. 3. This permits of the necessary lateral or sidewise movement of the barrel upon the stock, to open and close the barrel and prevents longitudinal separat-ion of the parts until this thumb screw is disengaged from the slot 18.

Extending downwardly from the under face of the barrel, near its midlength, is the pin or projection 19, as seen clearly in Fig. 3, the lower end of which is enlarged forming the disk-like portion 20, the latter being of such relative size as to be received within the enlarged portion 8 of the key-hole slot 7-8, while the member 19 is of such relative size as to be quite snugly received within the longitudinal portion 7 of said slot. As seen in Fig. 3, the member 19 is engaged in the longitudinal portion 7 of the slot, the shoulder 21 at the junction of such member and its head or disk portion-20 engaging the under surface of the side walls of said portion 7 of the slot. This allows of the necessary pivotal or lateral movement of the barrel without danger or displacement of the same.

In order to hold the barrel in its closed position against the tension of the spring 1G, we provide the latch member 22 pivotally mounted, as at 23, on the side of the stock, one end being provided with a portion Q4 adapted to project beyond the lower edge of the barrel, while its other end constitutes a thumb portion or lever 25 in position to be readily manipulated by the thumb or finger. A spring 2G attached at one end, as at Q7. to the side of the stock and its other end connected with the thumb portion Q5, between the end thereof and the pivot 23, serves to normally keep the fastening member in its position to hold the barrel closed, which position is that seen in Fig.'1.

From the foregoing it will be seen that with the parts assembled as seen in Fig. 3, when in operative position, the fastening member is in the position seen in Fig. 1, the barrel being locked against lateral movement. lV'hen it is desired to open the barrel, the thumb member Q5 is pushed in the direction of the arrow a in Fig. 1. This moves the member 24 downward in the direction of the arrow 7) in Fig. 1 and as soon as the upper face of this member passes the lower edge of the barrel, the spring 16 which is compressed by the closing of the barrel, forces the latter laterally into the position in which it is seen in Fig. 6. As the barrel is pushed into its closed position, when it has fully reached its closed position,'the spring it@ causes the latch member 22 to return to its normal position and automatically loclts the barrel closed.

It will be understood that the spring 16 is put under compression by reason of its bent end engaging in the longitudinally-extending curved slot 1st, which slot, however, were it not for the necessary longitudinal movement of the barrel with relation to the stock in order to permit of the entire removal of the barrel from the stock, might be merely a hole in which the bent end of the spring would be received.

vWhen it is desired to entirely remove the barrel from the stock, the thumb screw 11 is turned outward till its inner end is disengaged from the opening 10, the barrel is moved laterally into the position in which it is seen in Fig. 6, and then the barrel can be moved bodily toward the right in said Fig. (3, when the pin 19 moves along its-slotY allowing the head or disk Q0 to be removed from the enlarged portion S and the barrel is disengaged. Reverse movement of the parts places the barrel into position again, when it is swung into closed position and there held by the fastening device as hereinbefore described.

t is to be understood that the adjacent contacting faces of the barrel and stock are dat and parallel, as will be clearly understood upon reference to Figs. et, 5 and G. The'extraetor mechanism is disposed between these adjacent faces, being disposed practically within a chamber and longitudinal groove in the under face of the flat portion of the barrel. Fig. 3 clearly illustrates the relative position of these parts. Fig. S shows such parts enlarged and in their relative positions but detached for better showing. This extractor mechanism embodies the extractor slide 28 which is mounted for movement in a longitudinal groove or channel 29 in the under face of the barrel, being provided at its outer or breech end with an angular offset 80 which is shouldered, as at 3l, to engage the flange of the shell or cartridge, as seen in Fig. 3, this otl'set portion resting normally, that is when the barrel is closed, in a correspondinglyY shaped recess at the end of the barrel in which position it is clearly shown in Fig. The forward end of this slide is halved or rabbeted, as seen at 32, and has therein an opening 33. Upon this halved ont or rabbeted end is disposed an offset portion Se of the link or connector 35, which oti'set portion has an opening 3G designed to coincide with the opening in the eX- tractor slide, a pin or other connection 3T passing' through these two openings, as seen in Figs. and l0, whereby pivotal movement is provided between these two parts. The opposite end of this link or connector is provided with an opening 3S and this end is received within annular groove 89 in the disk d0, this being provided with an opening -ll for the passage of a screw or pin l2 or other means which serves a pivotal connection between the connector and disk. -Projecting downwardly from the under face of this disk is a lng or pin 43 which works in the slot 9 of the upper face of the stock.

In Fig. 5 the parts of the extractor mechanism are shown in the position they occupy when the barrel is closed. The extractor slide is at the innermost limit of its movement. The link or connector stands nearly parallel with the bore of the barrel and the pin is nearly to the limit of its forward movement. Fig. 9 shows the second position of these parts, that is the position which they assume after the barrel has commenced to open but before it has been moved to its greatest extent. The link or connector has moved until itI is in line with the slide '28 and the pin et3 is also in such alinement. The disk O has moved bodily toward the breech end of the barrel, it being noticed that the depression il in which this disk is disposed is of greater dimension longitudinally than the disk, so as to allow of its bodily movement without endwise movement of the slide. F ig. l() shows the third position of the parts, that is the position they assume when the barrel is opened to its fullest extent. The construction is such that the chamber in the barrel is opened beyond the standing breech before the extractor slide is moved to start the exploded shell for extraction, then by the eccentrically operated movement, the vextractor slide quickly pushes the shell from the chamber. This is due to the movement of the pin 41-3 in the inclined slot 9 of the upper face of the stock. As the barrel is closed, the reverse of these movements takes place, the eccentric movement created by the loosely mounted disk and its connector or link serving to draw t-he extractor slide fully within its groove before the end of the barrel reaches the standing breech, so that everything is clear for the barrel to move back to its closed position where it is securely fastened by the fastening device 22 hereinbefore described. This automatic opening of thefbarrel and the automatic eX- traction of the exploded shell by means which permits the chamber in the barrel to be opened beyond the standing breech before the extractor slide starts its endwise movement and this movement then made rapid by reason of the eccentric mechanism, are considered essential features of the present invention.

From the foregoing, it will be seen that we have devised a simple, cheap, compact, efficient and reliable barrel actuating and shell extracting mechanism, and while the structual embodiment of the invention as hereinbefore disclosed is what we at the present time consider preferable, it is evident that the same is subject to changes, variations and modications in detail, proportion of parts etc. without departing from the spirit of the invention or sacrificing any of its advantages. XVe, therefore, do not intend to restrict ourselves to such details, proportions of parts etc. as hereinbefore disclosed, but reserve the right to make such changes, variations and modifications as come properly within' the scope of the protection prayed.
