Like parts are indicated by similar charactors of reference-thruout the several views. While. the features of invention herein shown and described may be embodied -in either a repeating rifle or shot gun of either large or small caliber ithas been particularly designed as a small bore shot gun, and has been embodied in agun of thirty-sin gage, which is equivalent in sizetoa forty-four caliberrifle. There is at present a growing demand for small gauge shot guns for ,the use of women, and for men w-itlrhighly-developed sportinginstinctand a willingness to give the game a greater chance by}employing a reduced quantity of; shot coveringja smaller pattern or field.

7 It is to be understood, :however, that the invention is not limited to small'ga'ge shot guns,'but is equally applicable toshot guns 1of larger gage,-and-also to rifle construc- 1ons. i r V the other. 'nected with the stock 1, whereby upon d1sinduces wear of the connecting parts, and

results in. looseness of the joint, and more or less play orlack of rlgidlty between the barrel and stock and necessltates some form oftake'up device. Such construction, however, has'heretofore been proven unsatisfactory and undesirable. In the present instance, the barrel 2 and receiver at are permanently and integrally united one with The receiver is detachably conmounting the gun the receiver and entire action mechanism remains upon the barrel and are entirely removed from the stock. To permit such engagement and removal of the receiver, the stock 1 is provided with a mortise or recess 5, as shown in Fig. 2 with in which the receiver is detachably engaged.

The receiver contains in the upper portion thereof a substantially cylindrical chamber for the reception of the reciprocatory breech block 6, beneath which is a rectangular elongated chamber containing the vertically swinging carrier 7. The receiver 4; is open at its rearward end as indicated at S in Fig. 13, and the breech block 6 is inserted within the upper portion of the receiver thru this open inner end. The breech block is of a general cylindrical form agreeing with the contour of the breech block chamber, within which it is free to slide to and fro. end of the receiver 4 is provided with a. clo* sure plate 8, having a screw threaded head 9, engaging in and forming a closure for the rear end of the breech block chamber. The

closure plate 8 is slightly resilient and has a circular depression in the outer face thereof'forming on the innerside of the plate 8 a boss 10, engageable in a hole or socket 11 in the rear wall of the receiver 4:, when the plate and head 9 are adjusted to their final position. By rotating the closure plate 8 the head9 is screwed into or out of the orifice of the breech block chamber, and upon the finalturn-in' the feeding operation the plate 8flis under such tensionthat the boss 10 will be projected intothe hole or socket 11 by the resiliency of the plate to lock the parts in their final adjusted position. It will be obvious that this closure plate may be removed or replaced by manual effort without the ne- 4 The rear '8 at the rear end of the receiver.

ceiver 4 15 provided ad acent to its rear end in its engaging position by theclosure plate The rewith a laterally projecting face in which is located the trunnion stud 33 of theswinging carrier. This laterally projecting face 35 is undercut or slotted in its lower edge as at 36, Fig. .13. The trunnion stud 33 is provided with a peripheral groove'37, which registers with this undercut slot 36, when the pin is in its normal position. The cover plate 34 is of such thicknessas to project within the slot 36 and into the groove 37 of the pin 33, overlying the action bar: and slot 28 as shown by dotted lines in Fig. 5. The cover plate is provided at its extremity with a projecting tongue or finger 38, which engages in a corresponding notch 39, in the lateral edge of the closure plate 8 on the end of the receiver 4, when the latter is in its closed position. The locking engagement of the closure plate 8 and thecover plate 34 will be obvious from Figs. 5, 12 and 13. V

The carrier 7 v is recessed ormortised and contains therein the oscillatory spring ac tuated hammer 40, pivoted at 41 and actuated by the main spring 42 secured to the underside of the carrier'7 and connected to the hammer 40 by a stirrup 42. The spring 42 normally tends to forcibly project the hammer 4O forwardly about its pivotal connection41. It is temporarily held against such Vmovement by the L-shaped sear 43 pivoted at 44 within the recess of the carrier and having a shoulder 45 engaging a corresponding shoulderupon the hammer 40, into engagement 'with which it is moved by' a comparatively light spring 47. The mortise of the carrier 7 also contains the primary portion 48 of the divided firing'pin, the secondary portion of which is carried by the breech block 6; The primary firing pin 48 is mounted for both longitudinal move- 'ment and depression within the carrier 7.

It has a sliding pivotal engagement upon a transverse pin 49, which passes thru a slot 50 in the primary firing pin 48, and is normally held in elevated position by a spring finger 51, beneath the firing pin 48, which tends to oscillate the firing pin 48 upwardly about its pivotal pin 49. At the same time the primary firing pin 48 is free to move longitudinally under the impact of the hammer 40. The upward movement of the firing pin 48 is limited by the engagement of a shoulder or lip 50 on a dependent tongue 49 with a stud or pin 51 projecting from the inner side of the carrier. The

- firing pin 48 is depressible against the tension of the spring 51' to accomodate the carrier to the position of the breech block 6 during the closing movement of the parts.

As heretofore described the cartridges are temporarily retained in the magazine 3 by the spring detent finger 22 so long as the magazine is disconnected from the receiver. However, upon the lnward thrust of the magazine, the beveled nose of the detent finger 22 engages with a cam projection 52, lo

cated at one side of the receiver as shown in Figs. 3, 15 and 16. This engagement of the detent finger 22 with the cam projection 52 flexes the detent finger outwardly out of the thereto a cam surface 55, which is engaged by the nose 56 of the carrier upon its upward movement to yieldingly press the spring finger 54 and stop 53; outwardly out of engagement with the cartridge which upon its release by the stop 53 is after a slight rearward movement reengaged by the stop 57. This stop nose 57 is carried upon a transversely arranged depressible stop arm 58, arranged transversely beneath the forward end of the receiver 4. Thestop arm is normally pressed upwardly to project the stop nose 57 in the path of the cartridges by means of a flat spring 59. See Fig. 4. At its free end the transverse stop lever 58 has an upwardly extending finger 60, (see Fig. 5) which projects into the path of travel of a cam shoulder 61 upon the action bar 26. It is to be understood that the temporary stop 53 is moved to disengaging or outwardly flexed position by the swinging carrier 7 only as the carrier is moved to its upperor closed position. The main stop 57 is at sometime in engaging position, and intercepts the rearmost cartridge in the magazine upon its release by the temporary stop 53. Upon the rearward movement of the'action bar, the cam engagement of the lug 31 in'the cam groove 32 depresses the carrier 7 thereby releasing the temporary stop 53 which moves inwardly under the tension of the spring finger 54. As before stated and as shown in Figs. 15 and 16 the temporary stop 53 extends beyond the stop 57, so that the cartridge when released from the temporary stop 53 is permitted a very short rearward movement before being again arrested by the main stop 57. This move ment brings the flange of the cartridge butt beyond the end of the temporary stop 53. Upon the release of the temporary stop 53, by the depression of the carrier, (the cartridge being then held by the main stop 57), the temporary stop 53 will be moved inward beyond the flange of the first cartridge and in position to stop the second cartridge of the series, but will have no influence or control over the first cartridge, which will be released by the depression of the main stop 57. The temporary stop being thus in posiaffords-a simple, detachable pivotal connection between the 1 hook and breech block,

whichmay be engaged and disengaged without the use of too-ls. It is merely necessary to insert. the ear 73 loosely within the recess 74: thru the slot 28 in the side of the receiver. The wall of the receiver above the slot 28 overhangs the ear and recess thereby preventing lateral disengagement. The hook 30 is rabbetted .at 7 5 upon its upper inner side to ride upon the upper edge of the slot 28 in ,the receiver wall. This hook is also rabbetted at 76 on its 'outer faceto agree with and ride upon. the upper edge ofthe cover plate 34-, whenthe latter is in closed position. Thus the hook is guided and heldbetween the edge of the cover plate 34 and the edge of the slot 28 against disengagement from the breech block, during its reciprocatory movement.

The breech block 6 is of a general cylindrical form, corresponding in diameter to the upper chambered portion of the receiver and somewhat tapered at its forward end, the face of the truncated conical'portion agreeing substantially in diameter with the butt of the cartridge. At its forward end it is provided with the dependent lug, 65. is provided on diametrically opposite sides with extractor hooks 7 8 and 7 9. The receiver 3 is provided with an opening in one side thereof, normally closed by the breech block 6, when the latter is in itsforward or operativeposition, and opened by the retraction of the-breech block for the extraction'of the exploded shell. The shell is drawn from the chamber of the barrel by the extractor hooks 78 and 7 9, which engage the rim of the shell at diametrically opposite points. The extractor hooks are yieldingly mounted in order that they may re. lease the shell at the proper moment. The

extractor hook 7 8 on. the side of the breech block 6 opposite the exit opening 80 is pivoted in a suitable slot in the side {of the breech block and is provided with a beveled head capable'of a slight yielding movement outwardly against the tension of a rearwardly extendingtail, which bears against the body of the breech block within an extension of the receiving slot for the hook. The engaging j aw or shoulder on the operative head of the extractor hook 7 8 is beveled slightly backward to afford a cam like yielding engagement. The hook 79 at the opposite side of the breech block to the contrary has an abrupt engaging shoulder afiording a firm and positive engagement with the rim of the shell. This hook 79 is of somewhat difi'erent character. 'It is of much shorter length, and at its rear end is provided with an inwardly beveled lug 81, which engages in a corresponding pocket or hole inthe side of the breech block in lieuv of a pivotal connection. This beveled space or chamber for the effective or secondary portion of the divided firing pin, the primary portion of which is located in the carrier The secondary portion of the divided firing pin comprises a substantially cylindrical body 85, cut away at its lower rearward portion and having a diameter substantially fitting the longitudinal bore 86 extending forwardly from the rear end of the breech block ,6. This firing pin is provided with an extended tapered nose 87' projecting thru a reduced opening in the forward extremity or face of the breech block. It is further provided with a dependent finger 88, which extends clownwardly thru the bottom slot 89 of the breech block, and into the path of the primary firing pin section, 48. Projecting into the longitudinal bore 86 of the breech block is .a stop pin 90, which limits the rearward movement of the secondary firing pin and also forms a rest for aspring abutment member and guide 91. This guide and abutment member 91 comprises a disc like memher, having a diameter corresponding to that of the bore 86, and notched or recessed at its lowest point, agreeing with the slot 89. Located to the rear of this abutment and-guide 91, and in spaced relation therewith, is a second reciprocatory cylindrical guide member 92, also fitted within the bore 86 and provided with a groove or notch 93 registering with the slot 89. This support and guide member is also provided with a transverse notch in its lower end as at 94,

within which engages a transverse pin 95,

block 6, eccentrically positioned toward the inner side of the housing or that side opposite the exit opening 80. This ejector rod preferably terminates substantially flush with the face of the breech block at its forward end, but at its rearward end extends catory stem of such prior patent-ed construction might beemployed as the firing pin in associationwith the present form of oscil latory hammer. If a separate firing pin is provided, the depressible member 48 would continue to perform its function of a shell ators'finger and without the use of a special too-l. 'The trunnion pin having been removed the carrier is readily removable thru the lower open side of the receiver. Before doing this, however, theaction bar is sprung slightly outward to lift the lug 31 out of the cam groove 32; This return movement of the action bar from the carrier is prevented by the side plate 34. The carrier being removed from the receiver, the parts mounted therein are readily accessible thru I the'open bottom. or top of the carrier. 7 The;

primary firing pin 48 is easily disengaged by removing the transverse pin'49 after which the shoulder 50 on the dependent tongue 49 may be unhooked from beneath the pin or stop 51. By unscrewing the head plate 8 from the end of the receiver 3, the breech block 6 is readily removed therefrom after first disengaging the coupling hook 30. The latter is easily disengaged after the lowering of the. side plate 3%,.bywithdrawing or unhooking the upstanding ear of the hook 30 from the recess iii-the side of. the breech block, The various parts: are.

thus capable of easy access for inspection, repairs or cleaning. This isquite important particularly when the shooter is in the field or in some sparsely settled district where gun smiths and tools are not to be had.

It is necessary that the extractor hook 79 be yieldingly mounted to enable it to pass over the rim of the shell upon the forward movement of the breech block when advancing the shell into the chamber of the barrel in order that it may have a firm engagement therewith to withdraw the shellafter'the discharge. Iowever, it "is equally desirable that the extractor hook 779' shall not yield but shall be firmly held against such movement at the moment of ejection ofjthe shell when the breech'blockreachesthe rearward limitrof its stroke. To. this end, as

shown in the drawings, the breech block is given a limit of travel to a'point beyond the ejection opening. 80. In this rearward posileased the hammer.

tion of the breech block the extractor book 79 bears against the" wall of the receiver, which formsfan abutment or stop against lateral yielding movement and holds the hook stationary in relation with the breech block while the shell is being rotated about its point of engagement by he ejector rod 100.

A fire arm constructed as described is further economical in manufacture, inasmuch as no inside milling cuts or other operations dillicult to perform in the limited space are necessary. Every part of the arm may be machined from the outside, and is readily accessible for various manufacturing operations. 7 1
