. The body-cover; fabove described is adapted to set over and embrace, s0 to speak, a body. 21'

carrying an integral trigger-guard 28v and provided in oneof: its side faces with a longitudinal recess 129 in which'aboltV-unit (not shown) is adapted'to reciprocate. Attached to the rear end of the body 2Lis the ,usual'butt-stock 39 secured in place thereto byya" magazine-tube 3! which may be of any approved construction and requires no detailed description herein.

The complementary side- walls 22, 23 of the body-cover 20, before'referred to, are respectively formed with rearwardly-extending locating-lugs 32- 32 adapted to fit,'when the arm is assembled, insi m-ilarly shaped locating-notches 33 formed in the bod'yZ'lit Formed in the inner face of each of-the side-walls 22 and.23 of the body-cover 29 and'leading forwardly-from the locating lugs 32 is a longitudinalentry-groove 34 intersecting a verticaljlocking-groove 35,the lowerportion of the rear wall of each of which constitutes a vertical forwardly-facing locking-abutment 355 .for the p'urpose as will'hereinafter appear. The intersecting grooves 34 and together form what might be termed a T-shaped groove or cut in each otthe side-wal1s22 and ZS. From the foregoing, it will be understood that the inner face oi each of the side- walls 22 and 23 of the body-cover is provided with the features 34, and 36.

For the purpose of interlocking the forward unit (comprising the body-cover 20, the barrel 25 and fore-end 26, etc.) with the rear portion or unit (including the body 21 and butt-stock 30, etc.), a transverse locking-bar 31 is employed which is of general cylindricalformsave that it has its respective opposite ends milled ofi into substantially-rectangular form to provide each thereof with an axially-extending locking-lug 38. One face 39 of each of the said lugs provides a locking-abutment engageable with its complementary locking-abutment 36 in the body-cover 25, as especially clearly indicated in Fig. 2 of the drawings. I I

The locking-bar 37 is mounted in .and adapted to reciprocate in a guide-slot extending transthe locking-abutment 36 of the body-cover 2D.

and obliquely disposed with respect thereto.

- Intersecting the lower end' of the guide-slot 40 and correspondingly angularly disposed is a clearance-passage 4| freely receiving the threaded stem 41 of an operating-screw 42 extendingthrough and having threaded engagement with a threaded bore 43 extending transversely through the looking-bar 31', before referred to.

The lower end of the clearance-passage 4|, above referred to, is enlarged treat 44 to receive the knurled head-portion 45 of the operatingscrew 42, which head-portion extends diagonally downward beyond the under surface of the body 21 so as to be conveniently available for manual operation. 1 k

For the purpose of limiting the axial movement of the operating-screw 42, the head-portion 45 of the same is provided with an annular peripheral groove 43 into which extends a stoppin 4? mountedin the body 21. The upper face of the head-portion 45 of the operating-screw is beveled as shown and cut to provide an annular series .of sloping detent-notches 4'8 'engageable on occasion by the beveled rear endor nose 49 of a plate-like detent 5E The plate-like detent 50, above referred to, is located in a rearwardly-opening slot15l formed in the rear portion of a trigger 52 and is mounted with capacity for both reciprocating movement and slight rocking movementon a pin 53 ex tending transversely through the body 21 and serving, also, as a pivot-pin for the trigger-52. The forward end of the de'tent fifl is provided as shownwith a longitudinal slot '54 receiving the pin 53 to permit the reciprocatingmovement of the detent, as above referred to.

,The'detent 55 is also formed adjacent its under edge with a forwardly-extending spring-retaining finger 55 over which is set the rear end of a helical trig'ger-springfifi which is seated at its forward end against-the forward wall of a spring-pocketor recess 5'! formed in' the trigger 52 in position to open rearwardly therefrom and is intersected by the slot 5| therein.

From the foregoing, it will be seen that the spring 55- as thus constructed and arranged serves to not only urge the trigger 52 forwardly, but also serves to urge the detent 50 rearwardly, so as to engage its beveled edge 49 with the detent-notches 48 of the operating-screw 42 when the said screw is threaded into substantially its'home position.

The present invention is, as before noted,

mainly concerned with the take-down feature and associated parts of the firearm, so that details of the arm other than those. before referred to require no detailed showing or description herein, other than to say that the body 21 is provided. with a forwardly-extending lockingfinger or lug 58 which, when the firearm is assembled,overlies a locking-ledge 59 on the body cover 20 and serves at this point to prevent the vertical separation of the units.

With the barrel-unit and the butt-unit of the firearm assembled together as shown, for instance, .in Figs. 1 and 2,'the operating-screw 42 is sufiiciently tightened to draw the locking-bar 31 firmly downward so as to engage the rearwardly-facing locking-abutments 39 at its respective opposite ends with the complementary forwardly-facing locking-abutments 36 on the inner faces of the side- walls 22 and 23 ofthe body-cover 20.

Now, owing to the angular path in which the said locking-bar travels in the guide-slot 40, the surfaces 36, 39 and 4!] will engage with a camlike or wedging action to-concurrently draw the body-cover 20 (together with the parts associated therewith) rearwardly and downwardly with respect to the body 21 (and the parts associated therewith) and firmlyhold the said members together against all looseness. When'the operating-screw 42 is in its home position, so to speak, as'above described, it will be prevented from being accidentally loosened, as for instance by repeated shocks of recoil, by the engagement of the-beveled edge 49 of the detent 50 with the detent-notches 48 in the said screw.

' Now, should it be desired to take down the firearm, the operating-screw 42 is threaded outwardly until the upper edge of the annular groove 46 therein engages with the stop-pin 41, after which the continued turning of the screw will forciblylift the locking-bar 31 upwardly to the upper end of the guide-slot 40, at which time the locking-abutments 39, at its respective opposite ends, will be clear of the locking-abutments 36 of the body-cover and the lockinglugs 38 on which the said abutments 39 are formed will be brought into longitudinal alignment with the entry-grooves 34 in the inner faces of the respective opposite side- walls 22 and 23 of the body-cover. 1 It may be here explained that the initial loosening of the operating-screw 42 serves to withdraw its detent-teeth 48 from the beveled edge or nose 49 of the detent 50, so that the turning movement of the screw thereafter is free of re-' straint of such detent and also free of the clicking noise occasioned by the engagement of the said parts.

With the locking-bar 31 elevated .to the top of the guide-slot 4i] in the body 21, as above described, the barrel-unit, comprising the bodycover 20, barrel 25, fore-end 25, etc., is free to be longitudinally separated from the butt-unit, during which operation the locking-lugs 38 at the respective'opposite ends of the locking bar 31 will pass through the entry-grooves 34 and the lug 58 will be disengaged from the ledge 59.

'When it is desired to reassemble the firearm, the butt-unit and the barrel-unit are slipped longitudinally together, so as to' enter the lockmg-lugs 32 in the body-cover into the lockingnotches -33 in the body 21 and at the same time cause the ioek rlg mg's 3a or thelocking-barfl toreenter the interiorof the said body-cover zfl lthrough the entryegrooves 34. "Concurrently.

with theopejrat-ion just described; the lug 58 the ledgefifll will also be reengagedrg v i i Now, upon thezL-operating-screw- 42 being and tatedyso as' tothreadits stem" m into the threaded bore' liiflin' thelocking bar-jltthe said locking barwvillibe drawn downwardly to en gage, with a cam-likeaction, its rearwardly-fac ing lock'ing abutments'; 3'9 .withrthe forwardly v facing lockingabutments 36 of the body-cover 20." Whentheparts 3B and 39 just referred to are seated, thefurther turning of the operatingscrew 3 52 z'will serve to ;move' the 2 same upwardly on itsinclined pathfluntil"the uppervfaceiof its head-portion 45 seats=against'the under-face of theenlarged lowerend'M of the passage 41. -As,

the operating-screw 42' rises, as just'described, its" detent-notches '48 will be, in-the'latter part of the said. movement, reengaged with the beveled nose'tea of theI-detent '50,"to thus 'be securely held against accidental displacement; but capable of being forcibly rotated-when desired;

From thedroregoingmit will be seenthat the two unitszof thefirearm are firmlysecuredtounscrewing of 'theoperating-screw 42;thesame gether in a manner which prevents loosenesa despite slight variations in manufacturaor despite the wearingloflthe engaging parts, such, for in"- stance, as the abutment-surfaces 36 and 39.4:v

It will be furtherlnoted that the detent-teeth 4B are engaged withthebevelednose 49 of the detent 5B onlywhen theoperating-screw 42 is at substantially its home. position. t Thus, uponthe very quickly recedes from the detent, whichno "longer imposes restraintthereon, nor does it occasion"objectionableclicking during: the entire- 40F operation of the saidlscrew. Conversely, upon the operating-screw 42 being threaded home,

this action is almost entirely completed before the detent-notches 58s are reengaged with the nose '49 "of the detent 5b.

The invention mayfbe" carriedfoutother specific ways than that herein set forth without departing from the spirit and essential characteristics of the invention, and the present embodiment is therefore to be considered in all respects as illustrative and not restrictive, and all changes c'oming within the meaning and equivalency range of the appended claims are intended to be embraced therein.
