SPECIFICATION forming part of Letters Patent No. 371,668. dated October 18, 18g?.

Application tiled March 28, 1887. Serial No. 32f65. (No model.)

To aZZ whom it may concern.-

Be it known that I, JOHN M. MAELIN, of New' Haven, in the county of New Haven and State of Connecticut, have invented a certain 5 new and useful Improvement in Revolving Fire-Arms, of which the following is a specitication.

My invention relates to revolving firearms; and it consists in certain new and useful conro strnctions and combinations o f the parts of the same, substantiallyl as hereinafter described and claimed. t'

In the drawings, Figure 1 is a top plan view of aportion of a revolving lire-arm constructed x5 according to my invention. Fig. 2 is a side elevation of the same, with the cylinder in section, and breechplate. Fig. 3 is a side view of the bolt or latch used to lock the barrel to the frame. Fig. 4 is a lower` face viewv zo of the same. Fig. 5 is a bottom face view of the pivoted lever used to slide the bolt. Fig. 6 is an edge view of the same. Fig. 7 isa top view of the sliding cover used to confine the other parts in position. Fig. S is an edge z 5 view of the same.

B is the barrel of the arm, which has a rearward extension, b, over the cylinder, to lock it to the frame.

C is the revolving cylinder, mounted on The barrel B has on its lower side a projection, through which is the transverse hole d,

forming a pivot-bearing, by which it is pivoted to the frame in the usual manner.

35 Through the extension b, near itsrear end, thevertical mortiseb' is made, which receives the projection or stud b2 of the frame through it when the barrel is locked to the frame. The breech-plate b3 is attached to the frame 4o behind the cylinder.

The lock and handle are of the ordinary construction, and are not shown, 'as their application will be readily understood.'A Y The bolt or latch e is placed in a longitudi- 45 nal chamber formed in the upper side of the extension b, forward of the mortise b', and the bolt is made shorter than this chamber, so as to be capable of sliding endwise therein. This bolt has a transverse slot, e', in its lower side, formed widest at the end farthest off, in Fig. 8. A flat bar or lever, d', is made with the thicker or shouldered projection d2 on its upposition.

per side at one end and the head d3 pivotcd upon its other end. .The shoulders between,- the thicker end portion of lever d. and main 5f part. are-vertical to its face and rounded horizontally, as shown by dotted lines in' Figs. 1 and 5. This lever is narrow enough horizontallyto be received in slot e of bolt e and to just lill the narrow end of said slot when it 6( lies therein against the diagonal side thereof, as shown by dotted lines in Fig. 1`. A transverse slot is cut through the nearer wall, Fig. 4 2, of the chamber in extension b, considerably wider horizontally than lever d' and `wide 6 enough vertically to allow the thicker portion 1,r2 of the lever to pass through'it,.and opposite to this slot, through the opposite wall, (shown in the upper side of Fig. 1,) another slot is cut, of the same width horizontally at its outer end 7 as the end of the lever d', and growing wider on the rear sideas it goes inward, and ol' the proper depth to receive the thick end d2 of the lever. These opposite slots, which receive the lever d',` are also so formedfthat theirfront vertical walls are in the'sarne plane, at right angles to the extension b, and their rear ver-V tical walls are in the same plane and at an acute angle to the longitudinal axis of said extension, thereby forming atransverse chami ber for the reception of the lever, the narrow end of which forms its fulcrum,gan d within the other parts of which it can swing horizontally upon said fulcrumas a center, substantially as shown by dotted lines in Fig. 1. A 1 spiral spring, s, is placed in the chamber which receives the bolt or latch e, between the front end of the latch and the front end ofthe chamber, to hold the bolt or latch. in. its backward A cover, m, is also provided to inl close the latch e' in its chamber. -This cover has tongues m m on its end and sides, which t into slots'made in the walls of the chamber of bolt e, as shown by dotted lines in Figs. 1 and2.' 'y

To place the several parts in working` adj ustment I first insert the lever d in its trans- -verse slots with its end projection, d, uppermost. I then place the bolt or latch e in its chamber with its slot e downward and embracing the lever d', and place the spring s in position ahead of its forward end, and, lastly, drop the cover m on top of the bolt with the side tongues, mm, in the mortise b', and slide it forward into place, its tongues m m entering their slots in so doing. It will now be evident lthat by pressing against the head d3 of lever d the bolt or latch e may be drawn forward in its chamber and unlock the extension b from the stud d2, and that the bolt or latch will automatically lock into the stud whe the extension and stud are broughttogether. The lever d is confined in its place by the enlargement dz upon its end, which`engages behind theside of the bolt e above its slot e and pre- Vents the escape of the lever, and the pressure of the spring s upon the bolt and lever willv always keep the dat: face of the pivotedhead d3 of the lever against the face of the extensionb and exclude dirt, &c., from the slot of the lever at its widest end. By the .pressure of the thumb behind the pivoted head d3 it will be kept against this face of the extension asit nieves forward, and the slot of the lever will always be kept covered, the lever moving endwise through its chamber to allow of this. By

this construction I obtain the advantages of 'a directsliding cross-bar in moving the bolt or latch e forward with the greater power and freer action of the lever, together with simplicity and durability in construction.

What I claim as new and of my invention 1s- 1. The combination of the barrel-extension b, the frame-stud b, the sliding bolt e, providedwith slot e', and the lever d', pivoted in one side ofthe extension, passing through said slot and projecting beyond said extension upon the opposite-side thereof, substantially as de scribed.

2. The combination of the barrel-extension b, the frame-stud b2, the sliding bolt e, provided With slot e', the spring a, and the lever d', pivoted in one side of the extension, passing throughsaid slot and projecting beyond said extension upon the opposite'side thereof,-

" substantial] y as described.v

in one side of the extension and projecting beyond the other a'nd passing through said slot,

and provided with enlargement di, locking it behind bolt e, substantially as described.

4. The combination of the barrel-extension b, the frame-stud b2, the sliding bolt e, provided with. slot e', the lever d', pivoted in one side of the extension and projecting beyond the other and passing through said slot, and the head di, pivoted upon the projecting end of the lever, substantially as described.

5. The combination of the barrel-extension b, the frame-stud b, the sliding bolt e, provided with slot e', the lever d', pivotedin one side of the extension upon a fulcrum, upon which it is adapted to both swing laterally and slide longitudinally, and projectingbeyond the other face of Said extension, and the head d", attached to the said projecting end of said le ver and bearing upon said other face, substau tially as described.

6. The combination of the barreLeXtension b, the frame-stud b2, the sliding bolt e, provvided with slot e', wider at one end than at -the other, the lever d', located in a slot pass- JOHN M. MARIAN. y
