Specification of Letters Patent. Application med April 29, 1910. serii Noissssc'.

To all whom, 'if 'muy concern L' Be it known that l, CHARLES J. JOLIDON5v a citizen of the UnitedStates, and a resident of Hartford, in thc county of Hartford and State of Connecticut, have mvented a new and Improved Blagazine-Firearm, of.

which the following is a specification..

My invention relates more especially to that class of lirearins in which the action isautomatic, that is, self-acting to successively supply cartridges to the barrel, set 4the hainmer and eject the shells after discharge, and the object ot' my invention, aside from the special objects, is generally to provide. a

device ot'ihis class having numerous novel features oi advantage and utility. i p

One form of device embodying the invention and in the use of 'which the objects sought may be attained is illustrated in theA accompanying drawings. in which Figure l is a view in side elevation of a lirea-rm embodying my invention, withparts broken away to show construction, the parts heing in their normal relative position with the. exception o^t` the hammer, which is shown as thrown baclf.`ready for discharge. Fig.

Fig. 7 is a detall 4View showing the (amstruction and operation ot the safety rlhe frame ol my improved lirearnr may he, constructed ol" any suitahle material-and generally ol `any desired forni, vincluding a grip porti-oni and a breech portion 8. The grip portion includes sitleparts 9 between `which is l'ormeil in the. usual manner a 'mag aline chamber. the latter being clos-eil at the rear by a 'hack-piece -lU containing a sub-' `st'antial portion ot the firing mechanism. llllelueech S'lms a barrel opening ll. and

an opening l tor av/ ln-eech-bolt. VVA cover 13 is suitably, attached tothe trame. closing the opening .toi-ming the liieech-holt chamber lst therein.

AIt is ot' atlvantagcfin devicesl of this Class thatthe barrel may be'readilyremoved or Fig.

'common form and construction, including Patente-d July 1,1913. i i

inserted in its place, and that it shall be 'securely retained therein. I have embodied in' my improved firearm means for accomplishing these results. Inv carrying out this idea.

the barrel opening l1 is formed on'one side with ribs and grooves 15, 16 andthe barrel 17 'has a.' 'raised segment-18 consistin of Vribs forming grooves betweenthem, w ich ribs and groovesmesh'with the grooves Eind ribs in the harrel opening when the fbarrel 1 s turned to its proper positionin the frame,

these ribs and grooves extending circumf, ferentially vot' the. barrel as shown-in Figs.

l andv 3 of the drawings, movablysecure the barrelthepenin has a recess. 19. on one side of fs, widt to receive the ribs and grooves on the-barrel,

In Order to re- 5 and the latter' has a stop 20, located to. err-.jV

gage a stop shoulder 21'on the frame tio limit the rotating movement ofthe barrel as it is being placed in position andtodetermine the proper the barrel. is turne 'to its proper position osltron thereof. When the ribs thereonyvll have vpassed out of the e l recess 19 and have-their ends located in line with the endsof t e ribs 15 -formin one side ofthe recess 19. A key 22 nice y 'tits the recess 19 to prevent rota.-

referably 8() tionofthe barrel from its proper position,

and' in order to retain-the key I provide Ait wlth s spring linger 23 having `its e'nd shoul! dered. as at 24 to engage notches 25, which construction yieldingly holds the key in place, its outer end hav-ing aIshouldei-' which may bereached through a nail groove 27 formed by cutting away a part ofthe "frame, as shown in FignfQ of the drawings.

The breechholt 28 may. generally be of;`

breech-bolt frame 2S) mounted' to slide-,ill

pin 253 is frictioniillyheld in its trpeiiilig",v

,which 'is constituted" in fact by a groove 35gon the inner face of the cap and registering grooves 36 in the end of the breech-bolt. As a means for frictionally holding the pin the tip 32 is recessed at its outer end as at 37, notches 38 in the pin 33 receiving the edges of the recess 37, thus preventing longitudinal movement of the pin. The tip is A.pressed against the pin so that the notches and edges of the tip will be constantly held in engagement by the breech-bolt retract- .ing spring 31, the force of which, however is not great enough to prevent removal o the pin by the exertion of a little force.

It is necessary in automatic arms of this .class that the opening movement of the breech-bolt shall be retarded long enoughA i retarding mechanism, which insures that the bullet has left the barrel before the opening of the breech is suflicient to allow gases to escape rearward.

A retarding sleeve 39 is placed upon the tubular projection 30 from the breech-bolt; a retarding spring 40 being located within the sleeve and between it and said tubular projection. A retarding sleeve trip 41 in the form of a lever is pivotally mounted on the frame and has a projection forming a cam release 42 extending through an opening 43 in the frameinto the path of movement of a cam lug 44 on the breech-bolt. This trip 41-has its end formed to encounter the end of the sleeve 39, in the preferred form of construction and as shown herein a notch 45 being provided in the end of the tri iii the operation of-this art of the device, as a cartridge is exploded the ressure of the ases in the barrel tends t rough the cartridge shell to move the breech-bolt reaiward, but the tension ofthe Spring 31 reinforced by that of the\'springl 40,"both springs exerting their .-force against'the cap 34 fixed upon the breech-bo t, yieldingly retards this openin movement' until the cam lug 44, engages t e cam-release 42, push-/ in the trip v41l downward andreleasing its en from engagement-with the sleeve 39. The breech-boltbeing now supported onlybythe tension of the retracting spring-31, ields more readily to the force of thegases in the breech-chamber,'such force being ex-. erted against the breech-bolt during the brief interval until the projectile 4passes from-the muzzle of the barrel and thereby relieves the pressure therein.4 The breechbolt under its momentum continues to move rearward until it has fully opened the 40, `and if this function of retarding the rearward movement' of the breech-bolt was confine.. to the one spring which retracts the breech-bolt, as in firearms constructed prior yto my invention, the force of this spring would require to be overcome at each manual movement of the breech-bolt rearward. By employing the mechanism hereinabove described I am enabled to reduce the power 'required in the manual operation of the breech-bolt by employing the retarding spring to retard the rearward-movement of the breech-bolt only, and -I am thus enabled not only to use a retracting spring of just suflicient power to retract the breech-bolt, but to also remove the action of the retarding spring upon the breech-bolt atthe time of such manual operation, this being accomplished by means of the finger piece on'the sleeve trip or latch 4l, by means of which the trip is moved from engagement with the retarding sleeve and this prevents the force of the retardingspring from acting upon the breech-bolt. In the preferred form of .construction and as shown herein this finger piece projectsfinto the trigger guard 'and is located infront of the trigger, so that the trig er finger of the hand holding the grip of t e pistol may be applied against the finger piece to operate it, and a comparatively light rearward pressure against the cap on the forward end ofthe breech-bolt extension at this time will be sufficient to .move the breech-bolt rearward and open the breech. A spring, clearly shown in Fig. 1 of theldrawings, tends to return the trip or latch to' its operative position when the finger forwar' movement ofthe breech-bolt to the firing position rthe ener stored in the retractin spring during t e rearward movement o the breech-bolt is sufficient` to carry the breech-bolt andthe retarding spring and sleeve to their forward positions in which the are at once locked by the'locking trip or atch.

-It is of importance in firearms of this character that means be providedt prevent inadvertent dischargef-;,n as by involuntary pull upon the trigger, unless the breech is iece is released, and on the returnr fully closed .and the breech-bolt in the forward tiring position. I

In order to positively prevent tiring at all times except when the breech is closed, I employ a safety check 46l pivotally attached in the frame ts-at 47. 'This cheek 46'Iha/s a nose 48 arranged to lie within a recess 49 of the breech-bolt Awhen the sanie is in the forward position. This check 46 has a lug 50 located over a projection 51 of the trigger and preventing upward movement of the back partv ofthe trigger 52. This part of thetrigger is preferably in the shape of a stirrup, the projection 51 rising from one or both sides of this rear part', and the magazine 63, of usual forni and construction, passing up through the opening between the side parts of the trigger. The trigger has a release shoulder 53 arranged 'to engage the tail 54 of the sear 55 to release it fi'oin the 'usual notch in the hammer 5G. rlllhen the the breech isaclosed and the tire arm'is in proper condition for discharge. Astthe.I

trigger is moved rearward, the shouldef 53v can engage the "tail of the Sear and move the Sear to release `the hammer, allowing t-lie latter to be forced forward in the usual manner to strike uponv the tiring pin. Upon the .discharge of the cartridge the force of the explosion causes the breech-bolt to be thrown rearward, whereupon the nose 48 of the safety check 46 is forced downward from the recess 49 of the breech-bolt. U

carrying the release lug 50 ldownward against the projection 51 on the trigger, the4 rear end of the latter also bei-ng moved downward.- It will be noted by referring to' Fig.- 2 that if the triggeris now pulled rearward the shoulder 53 will not engage tlietail vof the sear and therefore the seaiI will not be moved and no vfurthershots can be fired immediately following the first one from involuntary pressure on the trigger, or from failure to release the trigger', luntil the breech-bolt has again reached its forward posit-ion andthe safety Acheck has been, j nioved upward.

- :In order to rovide against. the accidental discharge,'as rom a shock or jar releasing the -sear from engagement with the haininer, I provide a lock that-holds the sear from disengagement with the hammer. ln this embodiment yofv my invention andv as shown herein thisl lock consists of a slide Aas 5 8 with its end 5 9 normally resting back of thesear-tail 54, thus preventing i'novement y of the 'sear to disengageit from the hammer 56. vA lock release 60 is pivotally attached tov the frame and has 'a'lug 61 engaging' an openingin 'the slide, as' plainly show n in Fig. 1.- The upper end'of the'lock release `byya spring G2, the pivot upon which the end of the release G0 toward the slide, by th e operation of the trigger, the slide will be moved downward and the end 59 removed from behind the Sear-tail. This operation will be readily understoodifrom a glance at Figs. l and 2, and it will be noted that the spring 62.1ests with one end against the frame, passing through a slot in the slide, which slot is of a length sufficient to permit the required movement of the slide without interfering with the spring.

I do not limit my invention and the scope of the following claims to the accompanying illustration and foregoing description of a device embodying the invention in its pi'eferrrd forni, as these may be departed from to a .greater or less extent without avoiding the invent-ion.

The construct-ion of the safety lock constitutes a feat-ure of my, invention. This consists of a pin rotatably mounted in the frame, the end of .the pin being split as at 71 to form a spring binding feat-ure to hold the pin in place. This pin is cut away on one side forming a recess 72 through which the trigger mayl pass in one position ot' the pin. The pin is provided at one end with sie -a knob 73 by means of which it is operated. 95

The pin opening 74 through the traine is enlarged-as at T'foi-niing a shoulder 76 against which the stop TT on the pinl strikesr jto limit the rotary movement (if the' pin.

It will be noted that when the parts are in the-'position shown in Figs. l and 2 the ,trigger'may lpass through the recess 79., but

when the parts are'in the position shown in Fig. 4 lthe ingerpipce of the trigger will pass undert-he edge 7S formed by the recess 105 and exert a wcdging action,` so that the'pin will not be turned backward and the trigger will be held against movement.
