This application is for the same invention as that involved in applicants former application of Serial Number 191,776, filed May 16, 1927, said appllcat on having been discontinued, this appllcatlon belng a refillng of the former applicatlon.
In the accompanying drawlngs the. numeral 1 indicates the frame of my 1mproved firearm that may be of any ordinary and well known construction and including a trigger guard 2, a stock or handle 3, a breech slide 4 and a trigger 5.
A hammer 6 is pivotally mounted on a hammer supporting pin 7 extended into the frame, said hammer having a spring recess 8 of annular form within which a main or hammer spring 9 is located, one end of said spring pro ecting into a groove 10 in the wall of the recess 8 and the other end of said sprmg engaging a groove 11 1n a head 12 on said pin. Said head is provided with ratchet teeth 13 that are engaged by a detent 14 on a detent bar 15 attached to the side of the frame The head 12 1s provided w1th a slot to receive a screw drlver as a means for tensiomng the spring 9, the detent 14 holding said head against turning movement and in maintaining the tension of the main spring.
A sear 16 is mounted on a sear supporting pin 17 extending through the frame and havmg on one end a finger piece 18 as a means for remov ng the pin when desired. A scar lip 19 pro ects from the sear in position to engage the cocking notches in the hammer, and a sear lug 20 projects from the side of the sear in position for engagement with a sear actuating finger 21 on a sear bar 22 pivotally mounted at one end on a trigger extension 23 from the trigger 5, and as shown in Figures & and 5 of the drawings. A sear bar spring 24.- extends with one end in a spring housing 25 formed on the inner face of the detent bar 15, the other end of said spring thrusting against a shoulder 26 on the bar 22 to force the actuating finger 21 upwardly. The spring has the double function of a trigger spring and a sear bar spring.
A ledge 27 is formed on the side of the bar 22 for engagement with a nose 28 on a sear bar controlling lever 29 pivotally mounted on the pin 17 and having a lever actuating pin 30 projecting from its side into a notch in the upper end of a butt piece 31 pivotally mounted at its lower end in the stock or handle 3, and as shown in Figure 3 of the drawings. A butt piece actuating spring 32 secured to the butt piece and pressing with its free end against said stock holds the upper end of said butt piece at the outer liInit of its play and with a stop 34: resting against a shoulder onthe frame 1.
A butt piece actuating lip 35 extends from the upper end of the butt piece in position for engagement with a similar lip 36 on the hammer 6 whereby the butt piece may be actuated by the hammer in a manner and for a purpose to be hereinafter described. A sear bar disengaglng lever 37 is plvotally mounted on the bar 15 in position for contact with the edge of the sear bar 22, the upturned end of said lever being adapted to pass into a sear bar dlsengagmg recess 38 in the under side of the breech slide 4:.
The operation of the mechanism thus far described is as follows lVith the hammer in 1ts cocked positlon, as shown in Flgure 3 of the drawings, the sear bar 22 disconnected from the sear 16 and connectlon between said parts is effected b a grip of the hand around the handle 3 whic presses the upper end of the butt piece 31 inwardly. This actuates the lever 29 to disengage the nose 28 from the ledge 27, permitt1n the sear bar, under the influence of the spring 24, toenga 'e with the lug 20 on the sear. The trlgger being now pulled the hammer will be freed and will be forced lnto contact with the firmg pm 39 and the firearm will be discharged.
In this operation of engaglng the sear bar with the sear the end of the lever 37 was moved into the recess 38, the sear bar thus having been permitted movement for engagement with the sear. As the breech slide '15 forced backwardly upon discharge of the firearm and in a manner common to structures of this class, the lever 37 is forced out of the recess 38 and contacts with the under surface of the breech slide. This movement of the lever 37: forces the sear bar from engagement with the sear, and reengagement of said parts cannot take place, even though pressure on the trigger be retained, until the breech slide has again reached its forward position, movement to said position being effected by means of aspring, not herein shown, but in a manner that will be readily understood by those skilled in the art. The parts will now be in the position shown in Figure 3 with the exception that the hammer will be down.
The lips 35 and 36 enable the hammer to be released from its cocked position by the use of one hand only, in which operation pressure upon the butt piece cannot be effected. In accomplishing this purpose the hammer is pulled back by the thumb of the operator, engaging said lips, thereby forcing the upper end of the butt piece inwardly and from the" position shown in Fi ure 3 to the position shown in Figure 5 anithereby actuating the lever 29 to permit engagement of the sear bar with the sear in the manner hereinbefore described. A pull upon the trigger when the" hammer is thus moved backwardly will disof but backward it will be followed by the lip 35 under the influence of the s ring 32, tending to move the butt piece bacliward, in which movement of the butt piece the lever 29 will be actuated to press the sear bar 22 downward, thereby disengaging the actuating finger 21 from the lug 20, but this disengagement will not be completed until the full cocking notch on the hammer has passed downwardly beyond the sear Ii 19.
Upon disengagement of the finger 21 from the lug 20 the sear will be forced by its spring into position to engage the half cocking notch on the hammer, in this movement the sear engaging the hammer at the edge just above the full cocking notch therein.
In order to prevent accidental firing of the piece when the hammer is in its cocked position I provide a safety device comprising a safety lever 41 pivotally mounted on the side of the frame just underneath the breech slide and having a sear controller 42 in the form of a hub projecting from the side of the safety lever into the frame and havmg a recess extending into the hub from its end to receive therein a sear locking lug 43 projecting from the side of the sear opposite the lug 20, and as shown in Figure 11. A sear releasing opening 44 is formed in the end of the hub to permit passage of the lug 43 when the safety lever is in one position, but to obstruct movement of said lug when said lever is in another position.
For instance; when the lever is in its safety position, as shown in dotted lines in Figure 11, the wall of the recess in the hub is in the path of movement of the lug 43 and the sear cannot be moved and disengaged from the hammer, but when the safety lever is in its unlocked osition, and as shown in Figure 1, and in otted lines in Figures 8, 9, and 10, the lug 43 may pass from the position shown in Figure 8 through the opening 44, as shown in Figure 10, thereby permitting disengagement of the sear from the hammer, as by a pull upon the trigger. When .said lever 41 is in its locking position its a safety notch 45 in the ed e will en a e g g t% thus locking lower edge 0 e breech slide, said slide in its closed position.
The safety lever 41 is removably attached to the frame and is held in place by means of a retaining lug 46 onsaid lever normally located within a groove in the frame, as shown in Figure 12. Said lever also has a safety lug 46' located just inside of the wall of the opening in the frame in which the hammer and sear are located, said lugs being adapted to be passed into and through a releasing notch 47 in the side of the frame terminating in said groove and the lug 46 to be passed from said groove through a notch 47 extending from said groove to the inside ofthe frame, all as shown in Figures said lever is pushed into place and is then turned into position, as shown in Figures 8 and 25 of the drawings, to secure it in place.
The lever 41 has a rib on its outer face to provide for a recess in which a ball detent 48 is located against a spring plunger 33, as
shown in Figure 24, which plunger has its end beveled to force said detent into a hole from said recess to enga e recesses 49 in the side of the frame to yiel ingly hold the lever in its locked or unlocked position. The ball is inserted through a. receiving opening into the recess and the beveled end of the plunger prevents the ball from escaping through said opening.
This lever 41 is also provided with a recess" in its under surface forming a retaining lip 50 that overlies the finger piece 18, as shown in Figure 1, and prevents removal of said ger piece. The pin 17 projecting from the finger piece fits lts hole in the frame suf-- ficiently close to provide enough friction to retain the finger piece in the position shown in Figure 1, but by swinging said finger iece to the right its end will be swung out rom underneath the lip 50 and the pin 17 may then be removed from the frame, thus releasing the parts mounted thereon.
A magazine 51 is held in the stock or handle 3 as by means of a magazine catch 52 having an u wardly extending lip 53 adapted to engage t e upper edge of an opening 54 in the side of the magazine, and as shown in Figures 22 and 23 of the drawings. The catch 52 is preferably formed integral with and as an extension from the magazine catch sup ort 55 located in an opening 56 in the stoc or handle and having a recess for the reception of a spring 57 that projects out of said recess and against the wall of the opening 56 as shown in Figure 22. The support 55 has a lug 58 on one side adapted to engage a wall of the opening 56 and oppose thrust of the spring 57, a threaded tang 59 extending from the support 55. An actuating tip 60 fits the threaded tang 59 and also an opening in the side of the handle 3. By pressing inward on the tip 60 the lip 53 may be disengaged from the magazine for removal of the latter.
An indicator to denote whether or not a cartridge is in the chamber in the barrel is located in the side of the breech slide, and as shown in Figures 1 and 18, this indicator being in the form of a pin 61 projecting slightly beyond the side surface of the breech slide when a cartrid is in place, but having its end not projecting yond said surface when there is no cartridge in the chamber in the barrel. In the latter instance, preferably thepm 1s flush with the side surface of the breech slide so that a smooth surface is presented. A presser 62 extends with itsend in position to engage the rim of a cartridge 63, when the latter is in a chamber in the barrel, this presser bein preferably in the form of a U-shaped spring and having one arm engaged with a groove in the inner end of the pm 61, and as shown in Figure 18 of the drawings. From this it will be seen that by rubbing the thumb or finger along the surface of the breech slide it may be at once determined whether the pin is or not projectin beyond the surface of said slide and, t erefore, whether or not there is a cartridge in the barrel.
An extractor 64 is formed preferably as a part of a spring bar 65 that extends along a cut away portion on the inner surface of the breech slide, the extractor being formed to engage the rim of a cartridge in a manner common to structures of this class. A retaining button 66is formed on the side of the bar to engage within an opening 67 in the side of the breech slide, and the end of the bar 65 is formed as a firing pin retainer 68 comprisin a lip extending into a recess in the side 0' the firing pin 39 to retain said pin a ainst backward movement under the force of its spring.
The bar 65 is normally of bowed shape and when strained to be placed in position it has considerable sprin tension causing the button 66 to be forced into the opening 67, re taining the bar in place with suificient resiliency to enable it to satisfactorily perform its function and the rounded end of this button also serving to osition the bar should it be slightly moved rom its position through the striking of a shell or otherwise. This prevents any liability of the parts bein jammed during the movements of the breec slide.
A breech slide holder 69 is mounted on the side of the frame or receiver 1 as by means of a hub 70 projecting into a hole in said frame. A nose 71 on this holder is adapted to en age a notch 74 in the lower edge of the breec slide, and as shown in Figure 1, to retain the breech slide inits rearward position when the last cartridge has been fired. This holder has a recess containing a ball detent to engage recesses in the outer surface of the receiver, as hereinbefore described with respect to the lever 41, said detent being inserted and retained in the same manner as in the lever 41.
When the last cartridge has been removed from the magazine 51 an actuating lip 72 on a magazine follower 8 1 that was held down by said cartridge is permitted to rise against the pin 7 3, rojecting from the side of the holder 69, t us exerting a pressure against said pin, which pressure is caused by the spring located underneath the follower 84 in t emagazine in the usual manner. This pressure causes said holder to be forced upwardly to engage the nose 71 in the notch 74 in with respect to the detent 48, is located in a recess in the thumb piece and is pressed by its beveled plunger, as in the case of the plunger 33, into a guide groove 78, and into a recess in the bottom of said groove when the thumb piece is in the position shown in Fig ure 2, to yieldingly retain said thumb piece in this position. The detent is inserted in its recess through a hole in the end of the thumb piece shown in Figures 2 and 15 and corresponding to that in the safety lever 41 here inbefore described.
A holding lip 79 on the inner end of the retainer 75 is adapted to engage a notch 80 in the end of the hub 70, this engagement of said lip and notch holding both the retainer 75 and breech slide holder 69 in place.
The retainer 75 is cut away on one side as at 81 to permit removal of the rod 76 when the thumb piece 77 is moved upwardly so that the ball detent therein is in the upper end of the slbt therein, the arts then being in the positions shown in Figure 21. The body part 82 of the retainer is adapted to be turned into a notch 83 in said rod and thereby hold it against endwise movement, and as shown in Figures 15 and 19, this when the thumb piece 77 is in the osition shown in Figure 2.
If the thumb piece 77 be moved downwardly from the position shown in Figure 1, by forcibly disengaging the detent from the notch 8, by considerable pressure upon the thumb piece, the lip 79 will be moved out of the notch 80, that is, the rounded notch 85 on the lip 79 will be located opposite the rounded edge of the lip 86, as shown in Figure 20, thereby permitting either the holder 69 or retainer 75 to be removed from the frame or receiver.
A very material consideration in the construction of firearms at the present time is the weight, and efforts are constantly being made to reduce this weight to a minimum degree within the bounds of safety and efiiciency. In the construction of this improved firearm I have found means to materially decrease this weight without sacrificing the elements of safety or elliciency. I accomplish this purpose in the following manner:
. stop lug 90 with an the barrel in the This enables tion may This firearm is of the well known type referred to commonly as a recoil gun, that is the breech slide is opened by the explosion of gases and their expansion, said slide being locked against backward movement when the discharge first takes place. The barrel is locked to the breech slide by means of locking lugs 88 located in grooves 89 in the inner Wall of the breech slide and therefore both the barrel and breech slide move backwardly a slight distance together, this movement effecting rotation of the barrel to unlock it from the breech slide that is opened to its full extent by the expansion of gases within the breech of the barrel. Backward movement of the barrel is stopped by contact of a abutment 91 on the frame, as shown in Figure 19.
A breech slide unlocking nut 92 is secured to the front end of the rod 7 6 and a breech slide unlocking rib 93 on the under side of the barrel and in the form of a portion of a thread fits a helical groove in a thickened portion 94 of said nut, said rib being of suflicient length, breadth and thickness to provide the requisite strength, and the thickening of the nut providing sufficient material for a groove of proper size to receive said rib. me to take advantage of metal heretofore unused for this purpose and thereby to materially reduce the thickness of the nut on the sides, which in prior structures has been thickened to provide sufficient metal for grooves to receive locking lugs on opposite sides of the barrel. I thus reduce the amount of metal and consequently the weight to a material degree as hereinbefore pointed out.
As the barrel moves backwardlv with the breech slide its rotation. effected by the nut 92 and rib 93, will turn the lugs 88 out of the grooves 89 and into the chamber 95 under forward end of the frame, and the slide is therefore free to move back- Ward as hereinbefore described.
