EUGENE G. REISING, OF EAST HARTFORD, CONNECTIGET.

To all whom it may concern: v

Be it known that I, EUGENE G. REISING, a

of East Hartford, in the county of Hart ford and State of Connecticut, have invented a new and Improved Firearm, of which the following is a specification. My invention relates to that class of firearms that are supported on the person when being fired, and an object of my invention, among others, is to so construct such a firearm that it shall beespecially simple in construction' and effective in operation. y

One form of firearm embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings, in which Figure 1 is aview in central vertical section through a firearm embodying my invention, the front end of the barrel being broken ofi. Y

Fig. 2 is a cross sectional view on plane denoted by dotted line 2-2 of Fig. 1

Fig. 3 is a cross'sectional view on plane denoted by dotted line 33 of Fig. 1, the

i lower part of the handle being broken off.

Fig. 4 is a view in side elevation, of the right hand side of my improved firearm, the lower part of the handle and the front end of the barrel being broken ofi' and parts being broken away to show construction.

Fig. 5 is a perspective view of the breechbolt.

While my invention 'is not limited to any particular species of firearm yetit is especially adapted for use in that type commonly called a pistol. Such a device has been selected by me for the purpose of illustration and description of my invention herein.

The upper part of the frame of my improved pistol comprises a receiver 6, and the lower part of the frame comprises a handle .7 anda trigger guard 8. The device is also provided with the usualtrigger 9, hammer 10, sear 11, magazine 12,1hammer strut 13, strut seat 14, and main 8 ring 15, all of which may be constructed 1nany suitable and convenient manner.

In my improved device there is a spring seat 17 toreceive the thrust of the main spring 15 at its lower end,- this spring seat resting against a magazine catch 16, 1n the formof a leverpivotally' mounted in the lower end of the handle, one end of said Specification of Letters Patent.

lever receiving said spring seat and the other end having a lip .to engage the magazine under thrust of the main spring and a thumb piece by means of which the lever may be operated. I

The pistol shown herein is of the break down type, the barrel 18 being secured to ceiver to locate a part of the body of the a pin next to the releasing groove within the locking groove 20 to thereby, lock thebarrel against swinging movement on the frame or receiver. A thumb piece 23 is secured to the end of the barrel lock and projects through a recess in the side of the receiver to a point where it is accessible from the outside for the purpose of operation. Said lock is seated against a lock operating sprin 24 located in a recess in the receiver. this description it will be seen that pressure upon the thumb piece23 will move the barrel lock against the force of the spring 24, and into position to register the releasing groove 22 with the lug 19, in which. position the barrel may be swung on its.=.pi vot that secures it to the frame.

A; breech-bolt is slidably mounted on the receiver, said bolt comprising a body 26 having retaining flanges 27 depending from opposite sides thereof and breech-bolt retaining bars 28 projecting forwardly from said flanges and underlying the side edges of the rear end of the barrel that overhangs the receiver to an extent substantially equal to the thickness of said bars, the cross sectional dimensions of the body of the breech-bolt being substantially equal to the cross sectional dimensions of the barrel at its rear end whereby the upper part'of the structure is smooth. The upper part of the receiver is cut-away for a portion of its length to "form a slideway 29 for across piece 30 that i the trigger and extends rearwardly along one side of the magazine and a sear bar 37 projects at an angle from the rear end of the trigger bar and in position to contact with the lower end of the sear 11. A compound spring comprises a base 38 and sear and sear bar springs 39-40 extending therefrom, the latter to rest, in contact with the sear bar 37 and the former to rest in contact with the sear 11. The scar spring structure is of inverted T-shape, the ends of the base 38 projecting beyond the springs being located in spring retaining grooves 41 located in the rear wall of the magazine chamber, the lower edges of said grooves being undercut to receive the beveled lower edge of the base, as shown in Figs. 1 and 2 of the drawings.

From this construction it will be seen that the spring structure may be readily secured in place by inserting the beveled edge of, the base into said undercut grooves and then forcing the base and springs backwardly from within the magazine chamber. The pressure of the sear bar and sear upon the springs will retain the spring structure in position and against any liability of disengagement when the magazine is not in place, and the magazine when in positionwlll assist in retaining the spring-structure in place.

A safety lever 42 is, pivotally mounted in a recess in the front edge'of the handle, the upper end of said lever projecting into the inclosure within the trigger guard to engage a notch in the trigger, as shown in Fig. 1 of the drawings, a spring underlying the safety lever forcing it into engagement with the trigger. except when said lever is manually operatedto release it from the trigger. The lower end of this lever is in convenient position to' receive pressure of the fingers of a hand grasping the handle so that when the handle is so grasped in the ordinary manner the safety lever will ofnecessity be operated to release. it from the trigger.

A trigger bar disengaging slide 43 is mounted 1n the receiver wlth one end located in a recess in the under side of the breechbolt, as shown in dotted lines in Fig. 1, and

the other end resting upon. the sear bar 37. When the breech-bolt is forced. backwardly,

this slide is forced downwardly to locate thesear bar below the sear and thus permit. the

latter free movement to quickly. en g1: the' hammer when the latter-is force ackwardly. This slide 43 is held in place by. a sear in 44 that projects through a slot in the slide.

The retainin flanges 27 on the breech-bolt extend below t e upper endgesof the sear pin 44 and the hammer pin 45, which pins are thereby locked in place by said flanges, and the entire firing mechanism is consequently locked in place by the manually operable barrel lock 21. When said lock is operated to release the barrel, the latter may be swung with its rear end upwardly and the breechbolt may be lifted out of place. When the breech-bolt is in place the sear and hammer pins are locked in'place.

The breech-bolt is provided with a firing pin 46 of any ordinary form and construction and arranged to be struck by the ham- 85 mer when the latter is released for firing action.

The spring seat 32, in the preferred form of my invention, comprises a collar slidably mounted on a spring su porting rod 47, said collar being prevented rom moving off the end of the rod in any suitable manner, as by a pin passed through the rod, and the opposite end of the rod may be provided with any suitable means, as a head, to receive the thrust of the spring. This provides a structure that serves its purpose as a breech closer and at the same time one that may be readily removed from the firearm without any liability of the spring escaping from its fastenings. v

The disengaging slide 43 is made from a very thin plate of sheet metal that may be stamped to shape, and in order that such a slide may be employed a shallow recess 48 is formed in the'side of the chamber in the frame containing the sear and hammer, said slide being slotted to receive the sear in 44 upon which the slide is mounted. 'Fhe 'slide thus has simply a vertical movement, 110

the recess forming a slideway and preventing any turning movement of the slide on its pivot.

In accordance with the provisions of the patent statutes, I have described the prin- 115.

ciples of operation of my invention, together with the device which I now consider" to represent the best embodiment thereof; but I desire to'have it understood that the device .shown is only illustrative and that the invention may be carried out by other means. p
