K I" do Patented Jan. 5, 1932 LMMESQ EUGENE G. BEISING, OF EAST HARTFORD, GONNECTICUE ASSIG-NOR OF ONE-FOURTH TO ALVA C. \VASHBURNE, OF PITTSFIELLD, MASSACHUSETTS FIREARM Application filed Novemberfifi, 1928. Serial No. 321,493.

My invention relates more especially to that class of firearms that are commonly held in one hand and otherwise unsupported when discharged, and whichare commonly referred to as pistols, and an object of my invention,

among others, is the production of a pistol.

that shall be comparatively inexpensive to produce and that shall, at the same time, be simple in construction and particularly effi- Oneform of a firearm embodying my invention, and in the construction and use of which the objectsherein set out, as well as others, may be attained, is illustrated in the accompanying drawings, in which- Figure l is a View in central lengthwise section through a firearm embodying my invention, the outer end of the barrel being broken off.

' Figure 2 is a side view of the same.

Figure 3 is a View in section on a plane denoted by the dotted line 33 of Figure 1.

Figure t is an isometric view of the breech bolt or slide.

Figure 5 is a view of the barrel lock. Figure-6 is a view of said lock looking from a point located at right angles to the point of view of Figure, 5. i

Figure 7 is an isometric view of thesear.

In the accompanying drawings the numeral 8 denotes the handle of my improved firearm or pistol, which handle is comprised in the frame that also includes a receiver 9 and a trigger guard 10. The handle has an opening extending lengthwise thereof for the reception of a magazine 11, and a trigger 12 is pivotally mountedin the receiver and projects into the opening formed by the trigger guard.

A notch 13 is formed in the upper edge of the receiver extending from side to side thereof for a purpose to be hereinafter set forth.

A barrel housing 14 is pivotally secured to the front end of the receiver and a barrel 15 projects forwardly from the receiver and has 3 housing. The extension 16 is reduced in size from that of the barrel, the end of said extension being formed to nicely fit a hole 19 in the back end of the housing 14. From this hole 19 forwardly the opening in said housing is enlarged to provide a spring-chamberQO in which a breech bolt spring 21 is located, one end of said spring thrusting against the back end of the chamberQO and the opposite end of the spring thrusting against a shoulder in a breech bolt actuator 22.

This actuator is somewhat inthe form of a sleeve surrounding the barrel extension 16 and normally at the forward part thereof. The under side of said actuator projects through a slot 28 formed through the under side of Ii under surface creating cheeks 28, the bottom of said groove resting and sliding upon the upper edge of the frame and said cheeks sl dably fitting the sides of said frame in the upper edge thereof. The checks 28 together with the side parts 26 completely close the notch 13 and all of the other openings through the side of the frame in the upper edge thereof. The side parts 26also cover the sides of: the barrel housing 14 for the greater part of its length from the rear end thereof forward.

The breech bolt is provided with any ordinary form of spring retracted firing 'pin 29 actuated by a hammer 30 pivotally mounted in the frame in any ordinary manner and having a'strut 31 pivotally attached at one end to the hammer and its opposite end engaged with a step 32 seated on a main spring 33 in a manner common I to devices of'this class.

A barrel. lock 3 1 is made in the form of a pin projecting through a round hole comprising registering recesses in a lug 35 on'the barrel housing and in the wall of the receiver 9 located opposite said lug and as shown in Figure 1 of the drawings. The lock has a releasing notch 36 to permit movement of 2 l the lug and enable the housing 14 to be 35 comprising a part of the hole for the pin,

lease the barrel.

and as a result the lug cannot be moved and the housing 14 cannot be swung on its pivot. A lock actuating spring 37 is seated with one end against the bottom of a hole projecting downwardly into the upper edgeof the receiver 9, the opposite endof said spring thrusting against a shoulder on a detent seated on said spring and'forci ng said detent against'a shoulder formed'byalnotch 38- ma-d-e in the lock 34 and as shown in Figures 5 and 6 of the drawings, Adisc 39 is secured to the endof the lock 34 outside of the receiver 9 and Within a recess in the outer surface thereof, and asshown 'in'Figure 2, said disc being rotatable insaid recess underneath one of the'side parts 26. A finger piece or button 40 is provided as a means for rotating the disc 39 to operate the bolt, said button being located under the lower edge'of one'ofthe'side parts 26. r

The pointed edge of the-disk '39 underlies the solid portion of the breech bolt 27, and when it is desired to unlock the bolt so that it may be opened the breech bolt is moved backwardly far enough to uncover the pointed portion of said disk, and "said disk is Ethen swung on its pivot until the button 40"engages the edge of a side portion 26.

This'will place the lock 34 in position to re- In this position of the parts the breech bolt is held slightly retracted 'by the disk .89 and consequently a disconamas hereinafter referred to is held in a position to prevent actuation of the sear by the trigger. It will therefore be seen that the hammercannot be operated while the barrel is open and firing is" therefore pre- 7 vented at such time.

A sear 41 is pivotally mounted in an opening 42 in thereceiver in whichzo'pening the hammer '30; is also mountedand from which it projeetsg The sear is actuated by a sear bar 43 pivotally attached one end tothe trigger 12' and extending backwardly there from through a groove 44 in the sideof the receiver and into a position to engageithe 7 lower end of the sear. A disconnector 45 is shdably mounted in a dlsconnectcr groove Y '46 in the side of the searv and'as upon a pin projecting from the bottom of said groove through a slot inthe disconnector, and as shown in Figure 1 of the drawings." The upper enclqofthe disconnector rests ina firing notch 47 in the under side of the breech bolt, and when in this notch,and a s sho wn in Figure 1, a pull'on the trigger will engage if thebaclr end: of the sear bar 43 with the barr'elislocated; i uding a frame' having a lower end of the sear 41, thereby disengaging it from the hammer in a manner that will be readily understood. When, however,

the breech bolt is moved backwardly the notch 47 will be moved out of registering position with vthe end" of the disconnector and the latter will be forced downwardly,* 7

thereby moving the rear end of the sear bar downwardly so that it caninot be engaged with the sear.

' A multiple springis provided for the trig mediate its ends lugs 50 located in notches in lips-projecting from thehandle 8 into "the magazine chamber, said [li'ps being formed by a groove made in theiwall of'sai magazine chamber and as shown in Figure 3 ofthe drawings.- Said-spring also comprises fingers 5-152, there being. twofingers 51 projecting from ithe base of: the spring and pressing-with their: upper endsagainst the sear bar43 while the central and longer finger 52 presses against the sear 41 tending to force itinto'engagement with vthe/notches g in the hammer30. 4

. Itwill be noticed that. this-spring is secured to the handle intermediate its ends and the fingers atone end operate parts of the firing mechanism while th'esopposite end of the spring acts to hold the-magazine", catch 49 in pos'itionto secure thefmagazine in place. I

In accordance with the provisions of the patent statutes I have describedthe principlesof operation of my inventiomtogether with the device Which I n'owconsider' to represent the best embodiment thereof; but I desire to have it'understood that the device shown is only illustrative, and that the in-.

vention may be carried out by' other ,means and'appliedto uses other tl an those above set out.:
