Fig. 20 is a fragmentary view in elevation of As illustrated, the rifle embodying the present invention is of the shoulder type and is adapted for selective automatic or semi-automatic firing, being provided with a self-loading mechanism. The rifle comprises a barrel 25 (Figs. 1, 2, and 6) 4threadeclly secured toa receiver 26 and a stock 21 fixed to the rear end of said receiver. A box cartridge magazine 28 is operatively attached to the receiver, being held by means of a pushibutton device 29 of well-known construction. A

forward hand grip or forearm 30, which serves thereto by a bracket 35. Passage 34 preferably extends through the end wall of the cylinder providing an expansion chamber in the Cylinder even when the piston is at the end of its travel. A

YhollowY piston rod 36 secured at one end to said piston is slidably mounted at the other end on a hollow guide rod 31, the latter being supported at its free end by a bracket 38 fixed to receiver 26. A compressed coil spring 39 is contained within rods 36 and 31 and acts to move piston 33 in the direction of the cylinder head. Forearm 36` covers and guards the moving parts connected to cylinder mechanism 32, 33 and is supported at one end by bracket 38, the latter h-aving a pai-r of grooves 38a (Fig. 4) formed therein for receiving a plate member a. fixed to said forearm. The other end of said forearm is secured to the barrel 25.

To transmit the motion of piston 33 to the mechanism in receiver 26, anv arm or connecting rod 46 connected at one end to piston rod 36 extends rearwardly to said receiver and is slidably mounted for reciprocation in a groove 4| (Figs- 3 and 4) formed in av laterally projecting portion 42 of said receiver. Groove 4| extends longitudinally for substantially the entire length of the receiver and opens outwardly so that arm 46 may be readily positioned therein during assembly. A. longitudinal slot- 43 in the wall of the receiver connects groove 4| to the interior of the receiver and a pair of longitudinally spaced lugs 44 and 45 carried by arm 4|) adjacent the end thereof extend through said slot into said receiver, said lugs being adapted to engage and actuate the reloading and ring mechanisms in the receiver in a manne-r more fully described hereafter.v

To cover groove 4| so as to prevent foreign material from entering the receiver through slot 43. and to provide. manual means for actuating the rifle mechanisms, a member 46 is slidably mounted in a pair of grooves 41V disposed in the side walls of groove 4| and has a handle 48 formed therewith. Slide 46 (Fig. 3) is connected to arm 46 by means of a retractable pin 49 mounted in-a recess 50 in handle 48. A coil spring 52 in said recess urges said pin into engagement with the rear end of a slot 53A in arm 40, the tip 48a of said pin bein-g formed with a pair of parallel sides spaced apart a distance equal to the width of said slot. A lug 54 mounted on the pin extends through a recess 55 in handle 48 and said lug and recess act as a bayonet joint whereby pin .49 may be held disengaged from slot 53. The latter extends forwardly from said pin so that movement of arm 4B to the rear will not be transmitted to slide 4'6 while rearward movement of the latter will retract said arm. A pin 5| (Fig. 3) resiliently mounted in a recess in the side wall of receiver portion 42 engages a recess in slide 46 and fixes the latter against inadvertent movement due to recoil and handling but does 4 not offer a sufficient resistance to materially affeet the manual operation of said slide.

A novel bolt mechanism 56 comprising a cartridge-engaging cylindrical portion 51 (Fig. 6) and a rear block portion 58 is slidably mounted for reciprocation in receiver 26. Portion 51 ex-V tends into the lcartridge chamber 59 of said receiver and is provided with a cantilever extractor spring 60 and an axially extendingy flange 6| for engaging a cartridge rim in the well-known manner during the forward motion of said portion into said chamber. Cartridges are fed into chamber 59 by magazine 28, the latter having a spring actuated follower 62 (Fig. l) for moving the cartridges into said chamber. The spent cartridge shell is ejected through opening 63 (Fig. 1) in the receiver during the rearward mo tion of bolt mechanism 56, being engaged by a lug 63a (Figs. 6 and 21) extending into said receiver on the side thereof opposite said opening and being pivoted thereby about extractor spring 60. in cylindrical portion 51.

Novel means for locking bolt mechanism 55 against movement yduring ring are provided and, as shown, comprise a. member 64 (Figs. 6 and '1) pivotally mounted on block 58 adjacent the front end of the latter and extending rearwardly in receiver 26. When member 64 is held in elevated position, as shown in full lines in Fig. 6, said member engages the ends of a pair of laterally spaced shoulders or abutments 65 formed in said receiver and provides a positive lock for bolt 56. Member 64v comprises a pair of arms 64a which are integrally joined at the rear or receiver engaging end of said member and said arms are pivotally mounted on both sides of a vertically extending central portion 66 of block 56 by means of a pin 61. To retract bolt 56, member 64 mut be lowered and to accomplish this a control link 68 is mounted for pivotal movement on one of arms 64a, a depending bracket 69 being preferably formed on said arm with an opening 16 therein for receiving a pin 1| carried by said link. A recess 12 in block 58 receives bracket 59- and an adjoiningrecess 13 receives link 68, the bottom wall V14 of the latter recess serving to support said link when the latter holds member 64 in elevated position and to guide said link during the pivotal movement thereof to control said' member. An opening 15 (Fig."1) in the lower half of control link 68 is adapted to be engaged by lug 44 on arm 46 (Fig. 3). VMovement of arm 4U rearward pivots said link and depresses member 64, rendering bolt 56 Lug 45 (Fig. 3)

a longitudinally extending pin 18 having a iiringv tip 19 and a depending sear engaging member 80 are rigidly attached. Member extends vertically downward and has a transverse crosssection in the shape of an inverted T, the lower surface of the horizontal arm of said T being provided with a tooth or shoulder 8l. A lug 82 is also fixed to barrel 11 adjacent the rear end of Ythe latter, said lug having an inclined surface 82a formed at the forward and upper end thereof. A bore 83 in bolt 56 receives firing pin 11, 18, the

Lug 63a normally extend-s into a groove 631)y latter.. extending centrally through cylindrical portion 51 of said bolt. Tip 19 (Fig. 11) is adapted in the extreme forward position of said pin to project beyond the end of said portion a suflicient distance to strike and ignite a cartridge held by said portion. A groove 85 is formed in the side wall of bore 83 to receive lug 82 and a slot 88 extends downwardly from said bore through the bottom wall of said block, scar-engaging member 88 being slidably mounted in said slot.

To operatively position ring pin 11, 18, a rod 81 (Figs. 7 and 10) extends into barrel 11 and has a head portion 88 which is xed in bore 83 by a bayonet joint comprising a lug 89 on said head portion and a recess 98 in the wall of said bore. A coil spring 9| is held under compression between head 83 of said rod and pin 11, 18, being positioned around rod 81 and within barrel 11. Spring 9| normally urges pin 11, 18 in the direction of its firing position.

Novel means are provided for insuring that bolt 56 is locked against' movement before firing can take place and that during movement of the bolt the firing pin does not project beyond the end of bolt portion 51. The means comprise a depending lug 92 formed on member 64 and a recess 93 in bolt 56 for said lug, said recess connecting with groove 85. When member 64 is in de- Pressed position (Fig. 9), lug 92 engages inclined surface 82a of lug 82 and retracts firing pin 11, 18

relative to the bolt so that tip 19 is drawn within recess 83. When member 64 is in elevated position so that bolt 56 is locked, lug 92 is withdrawn from groove 85 and permits free movement of lug 82.

A novel unitary trigger mechanism is connected to receiver 26 and comprises a housing 94 (Figs. 6, 8, and 12) having a trigger guard 95 formed therewith and grip 30 fixed thereto by a screw 86. To `cock the firing pin and control the release thereof, a scar `|83 (Figs. 8 and 12) and a lever |84 (Figs. 8 and 15) are provided and are pivotally mounted on housing 94 by a pin |85 carried by bearing members |86 formed with said housing. A shoulder |81 on sear |83 and a shoulder |88 on lever |84 extend vertically in substantially the same lateral plane when said lever and sear are in elevated position (Figs. 12 and and are adapted to engage shoulder 8| on member 88 as the bolt is returned from retracted position. As a result, firing pin 11, 18 is held while.

bolt 56 moves relative thereto into locked ring position and said firing pin is thus cocked against the resistance of spring 9| (Fig. l0). Sear |83 is normally held in elevated operative position by a spring |89 located in a recess ||8 (Fig. l2)

formed in housing 94 while lever |84 is similarly` held by a spring in a recess ||2 (Fig. 15) in said housing.

Lever |84 is automatically depressed and disengaged from member 88 by novel means which comprise a cam or lug |3 on control link 68 (Figs. 6 and 1). Counterclockwise rotation of link 68 which occurs at the end of the travel of bolt 56 from retracted position causes lug ||3 to e engage lever |84 and to depress the latter when control link 68 has raised member 64 into engagement with the ends of shoulders'65. Thus, the

firing pin cannot be released from cocked position until the bolt is locked in firing position.

Sear |83, if depressed after bolt 56 is locked, releases pin 11, 18, causing the latter to strike and ignite the cartridge, and novel means (Figs. 12 to 14), including a trigger I| 4, are provided for controlling the displacement of said sear. As

' shown, said means comprise a link' ||5 connecting said sear to said trigger and a cam ||6 for said link, said cam being integral with a cylindrical member ||6a rotatable through 180. A pin ||1 formed on said link is pivotally mounted in an opening H8 in said Sear, and a spring ||9 guided in-a recess in said link bears against said sear and tends to hold said link in xed position relative to said sear. A finger 2| carried by trigger 4 engages a shoulder |22 on said link. The latter is provided with an inclined surface ||5a for engaging one end of cam ||6 when said cam is in the position shown in Figs. 12 and 13. Pressure on the nger grip ||4a of the trigger which is pivotably mounted in a manner more fully disclosed hereafter causes finger 2| nto apply a downward force to shoulder |22, and imparts (as viewed in Fig. 13) a pivotal counterclockwise movement as well as a translatory downward movement to link ||5. The translatory movement depresses sear |83 While'the pivotal movement tends to free link I5 from finger |2| in such a manner that when sear |83 has released the firing pin, link ||5 is disengaged from the trigger by the further movement of the trigger. This automatically returns scar |83 to operative position while trigger ||4 remains pressed. The release of the trigger causes finger |2| to again operatively engage shoulder |22.

When cam ||6 is rotated throu-gh 180 and assumes the position shown in Fig. 14, the end thereof engaged by side I |5b of link ||5 presents a flat bearing surface to the right of said link. This prevents movement of said link to the right and causes nger |2| to remain in continuous engagement with shoulder |22, Accordingly, in this position of the cam, when trigger ||4 is pressed to depress sear |83, the latter remains disengaged from the firing pin until the trigger is again released. A set screw |23 (Fig. 16) is provided for fixing member ||6 in a desired position, and a lever |24, operable by a small special tool, is located on the exterior of housing 94 and is connected to member |6a to provide a means for changing the angular position of cam I6.

Trigger ||4 is pivotally mounted in a pair of recesses |25 in the side walls of housing 94 by a pair of pins |26 (Fig. 15) integrally formed with said trigger. A iiat spring member |21 (Figs, 8, l2, and 15) is provided to operatively position trigger i4, said member having the base portion thereof dovetailed in a recess |28 in the upper wall of housing 94 and being provided with a pair of arms |29 and |38 extending on both sides of sear |83. Arm |29 is curved downward to engage the rear end of trigger l I4 and acts as a cantilever spring to resiliently urge said trigger into inoperative position. Arm |38 has the end thereof held in a groove |32 in the side of housing 94 (Fig. 8).

A novel safety mechanism is provided and comprises a downwardly curved element |33 (Fig. l2) xed to sear |83 and a laterally extending shaft |34, said shaft having a slot or groove |35 formed therein in the same lateral plane as said element. The angular position of shaftA|34 is controlled by a lever |36 (Fig. 16) on the exterior of trigger housing 94 and when shaft |34 is turned so that groove |35 opens in the direction cf element |33, sear |83 is free for depression by the trigger to release the firing pin. However, when shaft |34 is turned so that the ungrooved periphery thereof faces element |33, the latter is engaged by said shaft and the sear is positively locked against movement.

To hold bolt 56 in retracted position after the last cartridge `from magazine 28 has been fired, a novel control member |31 (Figs. 6, 8, and 16) is provided and is mounted for limited pivotal movement on pin |95, said member, as shown, comprising a finger |31a,v and a rear bolt-en-gaging portion or arm |315'. A spring |38 normally holds arm |3117 in raised position and said arm is adapted to slidably engage a groove |39 (Fig. '1) in bolt 56. Finger |31a extends forward through a recess |49 in the wall of receiver 29 (Fig. 6) and a slot (not shown) in magazine 28. When follower 62 has introduced the last cartridge into chamber 59, finger |3111, is engaged thereby and tends to pivot arm |315 downward. Accordingly, when bolt 55 is retracted, said arm becomes free of groove |39 and moves downward to press against a lug |42 (Fig. 8) formed in the upper face of housing 94. As a result, the return movement of bolt 56 is prevented by the engagement of said Varm with the forward end of the lower side wall of groove |39.

In order to iix member |6a in either of its extreme positions against inadvertent and accidental movement a pin |43 extends into a peripheral groove |44 in said member (Fig. 15), said groove subtending an angular distance equal approximately to the amplitude of movement desired for said member. Groove |44 is provided with a pair of radial recesses |45 for receiving said pin and determining the two positions of said member. A similar means for controlling shaft |34 of the safety mechanism in its movement into operative and inoperative positions is provided and, as shown comprises a peripheral groove |46s radial recesses |41 and a pin |48, said pin being guided by said groove .from one recess to the other. Pins |43, |48 are resiliently held in operative position by means of a flat spring member |31 which is in turn held in housing 94 by arm |39 of spring |21.

To detachably secure housing 94 to receiver 29.

a lug 91 (Fig. 6) on said housing is insertable into a recess 98 in said receiver and a novel locking mechanism is provided at the rear end of the receiver. The locking mechanism comprises a pair of laterally spaced grooves 99 (Figs. 3 and 5) and a cylindrical member |99 pivotably mounted in said receiver, member |99 having a pair of grooves 99a. adapted to be in alignment with grooves 99 when said member is in inoperative position, as shown in Fig. 3, A pair of laterally spaced upwardly extending lugs |9| are formed on housing 94, and each of said lugs is adapted to t into one of grooves 99,9911. Lugs ||J| are provided with substantially.semicircular recesses |92 which are coaxial with member |99, when housing 94is operatively positioned in the receiver. Accordingly when member |99 is rotated through approximately 180 the ungrooved periphery thereof engages the Walls of recesses |92 and tightly locks housing 94 in operative position (Fig. 5). Rotary motion may be imparted to said member by means of an arm lila. attached thereto so as to be accessible from the exterior of the receiver (Fig. 8).

Novel means are provided for mounting the cartridge ejecting lug 63a and comprise a flat metallic strip |49 (Figs. 20 and 21) to which a cylindrical pin or shaft |59 is fixed, said pin hav, ing lug 63a formed therewith. Shaft 5B extends into receiver 26 through an opening |5| in the wall of said receiver and one end of strip |49 -lits into a slot |52 while the other end is provided with a projection |53 which engages a.recess |54 in said receiver. vBy raising the end of said strip from recess |54 and then pivoting the strip so that the other end is removed from slot |52, the strip, together with shaft |59 and lug 63a can be removed from the receiver.

vA novel adjustable rear sight mechanism |55 is provided for cooperation with a stationary forward sight |55 (Fig. 1) and as shown, (Figs. 17, 18, and 19) said mechanism comprises a bracket |51 which may be secured to or formed integrally with receiver 2t. A sight member |58 having a sighting recess |59 is adjustably mounted in said bracket. A pair of flanges |60 formed in the walls of said bracket extend inwardly and engage grooves 19| provided in the side edges oi member |59. To vertically adjust member |58, a shaft 152 is provided and extends through the side wall of bracket |51, said shaft having a peripheral groove |53 formed therein for engagement with a lug |54 formed on member |53. The bottom wall of groove 153 serves to x' the vertical position of member |58, said wall having flat portions |630., i551) and |530 which are spaced at different distances from the center of shaft 63 for engagement with lug |54. Rotation of shaft |52 determines which of said portions engages said lug and accordingly controls the adjustment of said member. To maintain lug |64 in groove |53 and in engagement with the bottom wall of said groove, a plate spring |55 is operatively held in a recess |96 in bracket |51 by a pin |61. Spring is adapted to bear against lug |64 and also against a second lug |58 formed on member |58, said second lug being similar to lug |54 and laterally spaced therefrom. A depending skirt |69 on member |58 cooperates with an upwardly extending iiange |19 on bracket |51 to prevent light from passing between said bracket and said member when the latter is in raised position. To disassemble the sight mechanism pin |61 is removed and this` frees member |58, shaft |62 and spring |55 for removal. Y

In operation, the rifle is adapted for either semi-automatic firing, i. e., one shot being iired for each pull of the trigger, or for fully automatic iiring, i. e., repeated ring, cam ||6 constituting the selector for the type of firing. The cycles of operations in the receiver beginning with the ignition of a cartridge are substantially similar for both kinds of firing.

The gases of the ignited cartridge enter cylinder 32 and actuate piston 33 which, in turn, moves arm 49 rearward (Figs. 1 and 2). Lug 44 on said arm pivots control link 69 (Fig. 6) depressing locking member 54 on 'bolt 55 and disengaging said member from abutments 65 to free the bolt for rearward movement. Firing pin 11 and 18 is retracted within bolt 56 by the depression of member 54, lug 92 engaging and holding said pin in non-iiring position. Further rearward movement of arm 40 is transmitted to bolt 56 by lug 45 which moves the bolt to the rear of receiver 25.

During retraction of the bolt, the spent cartridge shell is withdrawn from the barrel into cartridge chamber 59 and is ejected from said chamber through opening |53. The open cartridge chamber is filled with a fresh cartridge by magazine 28.

fter retraction bolt 56 is moved forward by spring 39, rod 49 transmitting the motion to said bolt by means of lug 44. Portion 51 of said bolt engages the rim of the cartridge and forces the latter into iiring position in the barrel and firing pin 11, 18 is cocked by lever |54 and sear |93, the latter members engaging member 89 of said firing pin. When bolt 56 reaches the end of its forward travel, there is a further forward movement of rod il which pivots link Si! and elevates locking member 64, causing the latter to engage shoulders E5. As bolt 56 becomes locked, lever H34 is depressed by cam |53 and is disengaged from iiring pin il', i3. Lug 92 is also rendered inoperative. Thereafter, depression of sear |93 by trigger M releases firing pin 71, 18 and ignites the cartridge to repeat the above cycle.

It is to be noted that if sear |83 remains depressed as the bolt returns from retracted position, it does not engage the ring pin and the latter is held cocked only lby lever I. As a resultyring automatically takes'place Vwhen bolt Eit becomes locked in ring position, lever |04 being then actuated, as above described, to release the firing pin.

For single shot firing, cam H5 is fixed so that sear |83 returns to elevated position immediately after release of the firing pin and while the trigger remains pressed. Thus, the trigger must be released to again become operatively connected to the sear and must be pulled after release for each shot that is lired.

For automatic or continuous ring, cam H6 Y is xed so that sear |03 is continuously connected to trigger H4 and remains depressed as long as trigger H4 is pulled. The firing continues until the trigger is released or until the last cartridge in lthe magazine is fired.

The first loading of the cartridge chamber can be accomplished manually by retracting slide 45 when the latter is connected by pin 4S to arm 40. After the last cartridge is fired, follower 62 actuates member |31 and holds block 56 in retracted position until the magazine is removed.

There is thus provided a novel rifle adapted for automatic or semiautomatic firing comprising a reciprocating bolt mechanism, a firing mechanism movable relative to said bolt mechanism and adapted to be cocked in said bolt mechanism and actuating means responsive to the ignition of a cartridge for energizing said mechanisms. The firing mechanism is released for igniting a cartridge only when the bolt mechanism is locked 1n firing position and novel safety devices are provided for insuring that this result be attained. A trigger mechanism is detachably secured as a. unit to the receiver and is provided with novel means for controlling the firing mechanism, a member of said trigger mechanism cooperating with the cartridge magazine to control the bolt mechanism after the last cartridge is fired from the magazine.

Although only a single embodiment of the invention has been illustrated and described, it is to be expressly understood that the same is not limited thereto. Various changes may be made in the design and arrangement of parts Without `departing from the spirit and scope of the invention, as will now be apparent to those skilled in the art.
