This invention relates'tofirearins of the shotguntype, and certain features of the 1nvention find peculiar adaptation in firearms of the over and under type,"such as disclosed in the John M. Browning Patents Nos 1,- 578,638-9. 1 y l The aim` of the invention is to provide a firearm ofthe character described with various features! of novelty and advantage, thereby providing a betterfirearm and reducing its cost of manufacture.

An important object of the invention is to provide, in a gun of the over and under type, an'improved, simplified and effective arrangement by means ofV which the extraction of a discharged shell from the barrel in which it has been fired, and the retraction but not the ejection) of an unred shell are effected when the gun is broken.

Other objects will be in part obvious and in part pointed out more in detailher'einafter.

The invention accordingly consists in the features of construction, combination of elements and arrangementof parts which-will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the appended claims. y n

In the accompanying drawings, wherein is shown, for` illustrative purposes, one ofthe many embodiments which'the present inven- 'tion may take Figure l is a view looking at the left hand side of the firearm, the stock being broken away to show theV firing mechanism within the receiver, the left 4hand side wall of the receiver being taken Viny longitudinal vertical section substantially on line 1-1 of Fig. 3, parts of' the take-down bracket being broken away; y

Referring to the drawings in detail, the barrel sec-tion and the receiver are generally similar in construction to the corresponding parts illustrated in the said Browning patents. The barrel' section (so termed for convenience) has a breech piece 25, an over bar- .rel 26,y and an under barrel 27. The receiver has a pair of forwardly extending parallel sidewalls 28 at the forward lower cornersof Abearing surface 24. The bearing element is adapted to be received by a two-partbearing Von the barrel section. One vof these parts is provided by the forwardly facing recess or groove 30 at the forward lower corner of the breech piece and adapted to receive the pin 29. The other part of the bearingis pro'- vided by a semi-circular recess 3l on the rear end of the take-down bracket 32 and adapted to receive the correspondingly curved surface 24 of the receiver. This takelown-bracket is generally similar in construction,arrangement and operation to that disclosed in the said Browning patents. It comprises 'a relatively narrow rectangular piece or block slidably mounted on the barrel sectionwso as -to permit of separation of the bearing yparts for the hinge element. To thisend, there is pro vided onV the under barrel, just forwardly of the breech piece, a depending lug 33 having avlongitudinal groove 34 at each side. Slidably engaging in these grooves are ribs V35 on the bracket. Pivoted to the bracket is a take-down lever 36, the forward end of which has a sliding catch 37 provided with a hook 38 adapted to cooperate with a ledge 39 on the bracket. The lever has a locking lug 40 which is adapted to take in behind the lug 33 when the lever is in the locking position shown in Fig. 1. Pivoted to the rear end of, and extending rearwardly from the bracket, is a cocking lever link 41 which is gener lly similar in construction and' function to the corresponding link, designated vby the numeral 8, in the Browning Patent No. 1,578,638. rlhe numeral 45 designatesthe forearm which is connected to, so as to slide' with, the take-down bracket by a screw or bolt 46. i

The gun is locked in its closed position by `a locking bolt mounted for sliding movement in the receiver beneath the portion 51 which forms a vertical bearing in which the stem or post 52 of the top lever 53 is journalled. The locking bolt is provided with a transverse notch 54: which receives an eccentrically positioned pin 55 depending from the lowei` end of the top lever post 52. This arrangement is generally similar to that shown in the said Browning Patent No. 1,578,638.

The locking bolt further has a longitudinally extending and centrally positioned slot 56 m through which extends the rear endV or arm 60 of a cocking lever 61. This cooking lever is pivoted on a pin 62 beneath the ltop `lever post and `has a forwardly extending arm 63 which is adapted to cooperate with the heretofore described link 41 in a manner similar to that disclosed in the said Browning patents.

mechanism which is located in an opening of the frame-like portion of the receiver. In the present instance, this firing mechanism is shown as having a left hand `hammer 71 yand a right hand hammer 72 which are respectively control-led by separate triggers 73 and '74%. It is to'be understood, however, that this disclosure is by way of illustra-tion only and, if desired, a single trigger, such asshown in the said Browning` patents, may be employed for controlling both' of the hammers. The hammers are pivotally mounted between a pair of ears 75 on a pintle 76.

The opposed faces of the hammers are recessed so as to accommodate the rear Vupwardly extending end of the coclring lever which is rearwardly of the pintle 76, clearly shown in Figs. 1 and 2. The rear-end of the cocking lever has a toe 79 which isfadapted to engage shoulders '80 on the hammers so that, when the gun is broken, each hammer, in the event that it has been tired, will be moved to cocked position, shown in Fig. The rear end of the cocking lever, Vwhen the gun is broken, engages inthe slot 56 in the locking bolt so as to hold the locking bolt in retracted position (see Fig. 2).

Reference will now behad to the ring Associated with each hammer is a sear 81 respectively controlled by means of the triggers through connectors 82. It will be noted that each trigger has a lug 83 which is beneath the rear end of the locking boltl when the latter is retracted so that the triggers cannot be pulled when the gun is broken. The sears are urged into operative position by springs 85, and the Vh ammers are'actioned, `when released, by springs 86 about the VSlidably mounted on the frame rearwardly ofthe top lever 53 is a safety device which has a. particularly simple and effective arrangement. It has a thumb-piece 90 with -a pin 91 extending through a slot 92 in .the top portion of the frame. On the under side of this top portion is a groove '93 in which is slidably mounted a latch block 94 which is resiliently held in .place by a vspring 95 about the pin 91. The block has, at its forward end, a depending lug `96 which, when the safety device is in safe or on position (as shown in Fig.2) lies above .the upper ends of the connectors so that the triggers can-not be pulled. `When the safety-device is moved forwardly to the "otlwposition shown in Fig.

1, this lugfis'forwardly of the connectors so that the triggers may be vpulled to lire the gun. The rear end .of thevblock has 4aligned projections 97 (see Fig. 10) which are adapted to engage in a notch 98 when the safety is in on position and to engage in a forward notch 99 when the safety is in off position.

-Reference will now be lhad-to the mechanisms forejecti-ng fired shells and retracting, without ejecting, unfired 4shells from the bores of the breech piece when the gun is broken. Separate ejecting mechanism is provided for each barrel, but as these mechanismsare similar in construction and operation, a description of one will apply to the other. For convenience, the ejecting mechanism, associated with the over barrel, will here be described, .and the corresponding parts of the ejecting mechanism for the under barre-l willV be Vdesignated by similar reference numerals primed. lThe extractor proper for the over barrel has a plate of the usual form with a flat stem 106 which fits Y in a longitudinally extending dovetail groove 107 in the vbreech piece. Both the groove 107 and the stem or shank 106 are dovetailed or undercut so as to hold the extractor inposition for sliding movement. The forward end of the stem 106 has an enlarged portion 108 which overlies and engages the side o-f the breech piece so as to prevent excessive wobbling or canting movement of the extract-or, it being necy essary to have sufcient play between the stein lli) from the groove, the bottom of the groove has an elongated recess 109 and extending through the enlarged port-ion 108 of the stem is a screw 110, the inner end of which engages in this recess. Immediately in front of the extractor and mounted for'sliding movement in the same groove 107 is an auxiliary piece 111 through which the extractor is operated. In the present illustrative disclosure, this auxiliary piece has an undercut rib 112 slidably engaging in the groove y107 and the extent of movement of this piece is limited'by a screw 113 which engages in theV recess 109. The auxiliary piece has a notch orl cutaway portion 114 in its lower edge providing a rearwardly facing cam surface 115 and a forwardly facing'cam surface 116. On the inner side'of the left handv wall 28 of the receiver and atthe forward end thereof is a cam portion 117 adapted to extend into the notch 114 of the auxiliary piece wheny the gun is closed. This cam porion 117 has cam surfaces 118 and 119 adapted to respectively engage the cam surfaces 115 and 116 on the auxiliary piece. It will be understood that, when the gun is opened or broken, the rear cam surface 119 will engage the cam surface 116 on the auxiliary piece so as to move the auxiliary pieceand the extractor vrearwardly and, during the ope-rationof closing the gun,the cam` surface 118 will engage the cam surface 115 so that the auxiliary piece will be cammed forwardly to the position shown in Fig. 1.

Provided on the barrel section, and, more especially, upon the take-down bracket 32, are actuators and 125, one for each extractor. These actuators are pivoted to the rearward endof the bracket 32 and straddle the barrels, as illustrated in Fig. 3. lt will only be necessary to describe the left hand actuator 125for, as stated, the ejecting mechanisms for the two barrels are similar. The actuator' 125 is pivoted, at its lower end, on a pin 126, the take-down lever being notched as at 127 so as to accommodate the actuator. Between the actuator 125 and a lug 128 on the bracket 32 is a plunger 129 and a spring 130 which normally tend to throw the actuator to the operated position shown in Figs. 2 and 5. The actuator is adapted to engage the forward end of the auxiliary piece. It hasV a shoulder 131 with which a scar 132 is adapted to cooperate to hold the actuatori in the operative or cocked position shown inr Fig. 1. This scar is pivoted on a pin 133 in a notch or slot -134 inthe bracket 32 and is normally urged into operative position by a spring 135. The sear 132 has Va rearwardly and downwardly projecting finger 136 which extends into a recess or groove 137 in the curved face 31 on the rear end of the takedown bracket. The bottom surface of this groove 137 constitutes' a cam.

The sear for the actuator 125 is controlled by the left hand hammer 71 acting through a rod 140. This rod is made of spring material and isv located for sliding movement in an opening or bore 141`in the left hand side wall 28 of the receiver. It, owing to its own flexibility, frictionally holds itself in any position of adjustment. The forward end of the rod is adapted to project beyond the 'curved face 24 at the forward lower corner of the receiver and into groove 137. The rear end of the rod has a head 142 provided with a slot 143 which receives the left hand proj ecting end of the pintle 76 on which the hammers are pivoted. The slot 143 is of such length asv to properly limit the extent of movement ofthe rod. The rear end and upper edge of the head 142 has a cam surface 144 with which a. pin or lug 145 extending laterally from the left hand hammer is adapted to engage so as to cam the rod forwardly upon the cooking movement'of the hammer. The head of the rod, at its rear end and at its lower edge, is bevelledY or inclined upwardly and inwardly as at 147, and the lug 145 has a bevelled face 148 which is adaptedto engage the bevelled face'147 of the rod when the'hammer is released tofire the gun.

The operation of the ejecting mechanism .for the over barrel Will now be described, it

being understood that -the corresponding mechanism for the under barrel will operate in a like manner. When the firearm is in the closed position shown in Fig. 1, the. actuator 125 is held in cocked position by the sear 132. The left hand hammer 71 is shown as having been released to fire the shell. When so released, the cam surface 148 on the pro# jection 145 will cooperate with the upwardly and inwardly inclined surface 147 on the connecting rod 140 to flex the rear end of this rod laterally and without moving the rod longitudinally. When the hammer is in the released position shown in Fig. 1, the projection 145is in operative relation to the cam l' surface 144r on the head 142 of the rod. Y When the gun is broken, the cooking lever will move the released hammer back tococked posi.-

ition, and when the hammer is so moved, the

projection 145 thereon, 'due to its engage` ment with the cam surface 144, will move the rod 140 forwardly, thereby projecting the forward end of the rod into the groove 137 and into operative relation with the tail end 136 of the sear 132. Also during the operthis piece forwardly independently of the extractor and positively moving the actuator from the operated position shown inr Fig.

2 to the operative or cocked position shown in Fig. 1. Also, the cam surface at the bottom of the groove 137 in the rear face .of the take-down lever will positively cam 'he connecting rod 140 rearwardly from the position shown in Fig. 2 to that shown in Fig.

Y 1. Furthermore, upon closing movement of Cil w: liu

the gun, the surface 160 of the breech piece (and through which the firing pins 161 extend) will engage the rear face of the plate 105 of the extractor and force the extractor to the forward position shown in Fig. 1.

In. the event that one of the barrels has not been fired before thegun is broken, the ejecting mechanism associated with that barrel will not be effected; that is to say, the actuator associated with that barrelwill be held in cocked position. For example, if th-e trigger-associated with the left hand hammer has not been pulled, and the gun is broken, the proj ection11-5 on that hammer will remain below the head 1112 of the rod. Therefore upon breaking movementof the gun, the rod is not advanced to the position shown in Fig. Q, 'out on the other hand, will retain the retract-ed position shown in Fio. 1. Upon breaking of the gun, the cam surface 119 will ngage'the cam surface l116 and thereby nove the extractor to extract the shell withut 'lioweven ejecting it. Upon closing movement of the gun, the auxiliary piece i l be moved forward into operative relation to the cocked actuator by the cam surface 118, and the extractorl will be moved forward by its engagement with the face 160 of the receiver. i

1t will he noted that the improved ejecting` mechanisms her-ein disclosed are characterized by their extreme simplicity in construction and their cifcctivcness in operation. WJhon the gi i is taken down, the space between the side walls 28 of the receiver is clear and tl ere are no projections extending from these side walls which are adapted to be caught and broken when handling or carrf-,Iing around the receiver in taken down con- Y dition. The actuators or ejectingl levers are carried by the barrel section anc. particularly by the take-down lever. Access may be readily had to these levers. They are very compactly arranged on opposite sides of the barrel section, and the assembly and construction are such that they do not require an increase in the width ofthe forearm in which they are housed when the gun is assembled. rlhe force required to move the connecting rod into Voperative position by the cooking movement of the hammer or out of operative position upon closing movement of "he gun is substantially negligible, a feature of iniportance as it is. desirable to permit the gun to be closed and opened with little effort as possible. rllhe rod 140, when in operative i position, positively engages and releases the sea-i' 132 from the actuator. It will be ol served that the rod 1410 is moved positively in both directions so that, in the event it should tend to stick, due to dirt or corrosion, it will be caused to slide in the direction in which it is urged.

Each actuator or ejecting lever is positively cockedupon closing movement of the gun, and l such cocking movement is effected through the auxiliary piece. By the use of this separate a xiliary piece 111, the actuator may be given a relatively large movement without the use of distance inulti'piying` devices, and the cooking movement of the actuator is effected independently of, and without throwingany duty onto, the extractor or shell when the same are cammed forwardly by the anvil face 160 upon closing movement of the gun. Upon initial closing movement, the auxiliary piece and actuator are moved forwardly bythe cam portion 117 with a relatively quick movement leaving the extractor 105 behind, and upon further closing movement the anvil face 160 will engage the head of the extractor (or the shell) camming the same forwardly, and during` the entire closing movement of the gun there is always a space between the extractor and the auxiliary piece. The auxiliary piece engages the actuator adjacent the free end of the latter, and the interengaging` cam surfaces 115 and 118 Vare spaced a considerable distance from the pivot pin 29 which means that relatively large leverages are employed in cooking the lever so that the gun may be more easily closed. The actuator has a swinging movement through a relatively large arc, thus permitting the spring 180, when the actuator is cocked, to be .properlycompressed, and insuring that the actuator, when released, will impart a. movement tothe extractor which Vwill surely and completely eject a fired shell.

.
