AUTOMATIC FIREARM. I

. No: 853,438. Specification of Application filed Augnst1B,1905. Serial No. 274,689.

1b all; whom it may concern.- Be it known that I, JOHN-M. BROWNING, a citizen ofthe United States, and a resident of I thecity of Ogden, in the county of Weber and State of Utah, have invented certain new and useful Improvements in Automatic Firearms, of which the followingis a specification, reference bein had to the accompan ing drawing, forming apart hereof.

Tliisinvent'ion relates to automatic firearms such, for instance, as are shown and described in Letters Patent of the United States No. 659,786, issued to me October 16, 1900;, an'd'the general object of the invention is to improve in certain particulars the arm shown and described. in said LettersPatent, although the improvements are capable .of being applied to other firearms of like gen eral character. 4 v

The invention concerns the taking down of the gun. In doing this, the handle upon the bolt mechanism by means of which the gun is manually opened and which handle Works in a slot *in the receiver, has to be removed before the bolt and its associatedparts' can be pushed out fromthe forward end of the receiver; Thisv handle therefore, in accordance with the present invention, is fastened to the bolt mechanism in such a way as to be readily attached and detached as. required.

Theinvention will be more fully described with reference to the accompanying drawing in which the improvements are illustrated in .a convenient and practical embodiment. g

- In said drawing: Figure l-is a view in side elevation of-an arm to which the improvementmay be ap' lied; Figs. 2 and 3 are sectional views of t e bolt carrier, Fig. 2 showing thehandle and its parts in'section, and Fig. '3 showing the handle in elevation;- Figs. 4 and 5 are respectively an'end view and a; view in side elevation of the handle; FFig. 6 is a view in front elevation of the bolt mechanism 'Figs. 7 andS are respectively'a top view and a side 'view' of the nut in'the handle and Figs. 9 and 10 are res ectively a View in. elevation of the spring an a view in .elevation of the pin in the handle.

. The'bolt mechanism, as in' the Letters Pat- 3 whichmoves backward in the receiver 6 together with the barrel upon-each recoil, and then moves forward again and closes. the breech. During this operationthe h'andle 2 .by the carrier may then be pushed forward upon the. carrier works in -a slot 7 as will be:

obvious from Fig. '1 and as has already been described injsaid Letters Patent. 7

In accordance with the present invention, the handle and carrier are. formedwith a sliding connection such as a dove-tail connec- Ttion, whereby the handle, when the gun is to.

be taken apart, may beslid out from the carrier and removed fromthe carrier and whereout of the receiver. In the present case, the 6 handle is shownto haves T shaped portion arand the carrier a corres ondingly shaped groove in which this T-sihaped portion is adapted to slide. In order to secure the handle within the groove in the carrier in I such a way that it may be readily attached and detached therefrom, 'means such as a pin '1) extendin through the handle so as to be accessible from the exterior thereofis provided. This pin is ada ted to engage a re- '7 5 cess c in the carrier an thereby to hold the handlefirmly Within the groove in the carrier.

. In order to keep the pin 5 in the recess 0,

any suitable means may be emplo ed, such,

for instance, as a spring (1, one on of which maya'but against the shoulder e upon the pin while the other end-of which rests against a nut f threaded in the endbf the handle. In this way the in-is normally held in its recess and ma be quickly and easily re- .Inoved' by the' ger. If desired, a grooveg may be provided upon theouterend of the piri in order thatthe end of the pin may be the more conveniently grasped.

- Various changes in the construction shown and described herein may be' made without departing from the spirit of the invention,

and the .improvementsare not limited therefore to the present embodiment thereof.

Furthermore, as was stated at the outset, the improvements are not'limited' in .a plication to the gun mechanism shown an described in the present case nor to the mechanism shown and described inthe Letters Patent above referred to. rco

I claim as my invention 1 1. In afire arm, the combination with the receiver and breech mechanism, of a handle detachablysecured to the' said mechanism in a-slot in the receiver, anduc 5 means in t e handle vwher'eb the handle may be secured to and detached from the bolt mechanism.

'2. In a fire arm, the combination with the receiver and breech bolt mechanism, of a 1'10 receiVer and breech bolt mechanism, of a handle for moving said mechanism, said handle working in a slot in the receiver and having a sliding connection with the bolt mechanism, and a gspring actuated pin adapted to fasten the handle to the bolt mechanism and accessible from the exterior of the handle whereby thehandle may be secured to and detached from the bolt mechanism.

4. In a fire arm, the combination with the receiver, breech'bolt and breech bolt carrier, of a handle having a sliding connection with the carrier and working in a slot in the receiver, a pin extending through the handle and adapted to enga e a recess in the carrier to lock the handle t ereto, and a spring to. hold the pin normally inthe recess.

This specification. signed and witnessed this 14th day of August, 1905.
