- lMPlQOVEMENT IN REAIOLVING FIRE-ARMS.

Specification forming'part of Letters Patent No. lihfififi, dated December 19, 1865 antedated December 7,1865.

To all whom it mat concern;

Be it known that I, EBEN T. STARR, of the city, county, and State of New York, havei'nvented certain new and useful Improvements 'in Revolving Fire-Arms; and I hereby declare improvements. Fig.2 is a central longitudinal vertical section of the principal parts of the same. Fig. 3 is a front view of the cylinder and the cartridge-guard, the latter being partly in section. Fig. 4 is ahorizontal sectionof the cylinder,eartridge-guard,andpartofthefi'ame.

Similar letters uof'reference indicate corresponding parts in the several figures.

This invention relates to revolvers which are loaded in front of the cylinder with metallic cartridges which contain a fulrninata' It consists in a novel device for preventing the cartridges and cartridge-shells from accidentally slipping out from or forward in the chambers of the cylinder, but which affords facility for the ejection of the discharged shells, or the cartridges themselves, if desired, from the chambers;

It also consists in a novel eiector'for ejecting. the discharged cartridge shells or-cartridges from the chambers.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A is the cylinder, constructed for loading in front-that is to say, havingbottdms to its chambers, or, in other words, not having the bores .of the chambers extended through its rear. This cylinder is applied to rotate within the frame B, and may be securedtherein in any suitable manner.

C is the novel device whichl term the cartridge-guard, arranged between the front of the cylinder and the frame 13', and close to the cylinder, for preventing the cartridges and discharged cartridge-shells from accidentally slippingout from or forward. in the cylinder. This guard consists of a plate or piece of steel or other metal of bifurcated or annular form, substantially as shown in Fig, 3, pivoted to the frame B in front of the cylinder and below the axis thereof. Its pivota is representedas being' formed in the same piece with or rigidly attached to it, and fitted to a circular hole bored through the front part of the frame, and secured against longitudinal displacement, when the cylinder is -removed from the frames bymeans of a transverse pin, b, in-- serted through the 'frame B and through a groove, 0, in the said pivot; but the guard 1 may be pivoted to the frame in a similar posi tion in anyother manner. The guard is large enohgh externally to cover portions of the months of as many ofthe several chambers bl) as are noteither wholly or partly covered by therear end of the barrehwhich fits close against the front end of the cylinder. This is illustrated in Fig. 3, in which the rear end of the barrel is shown in; red'outline covering the mouths of the two upper chambers, and the mo'uths of the other chambers are all shown as partly coveredby the fork or ring, so that the cartridges contained therein cannot slip forward, the shells-of the'cartridges which are employed being just of the full length of the chambers. The guard is held in the necessary position to do this by means of a-spring, d, which is secured by a screw; d, to the left side of the frame, in front ofpthe, cylinder, and which presses the guard into contact with the front journal, e, or axis-pin. The said spring d'appears on the right side of the guard in Fig.3; but it must be borne in mind that this is a front view,'and representsthesides reversed. The opening t-provided in .the'guar'd .to admit the front journal of the cylinder or the axis-pin is wide enough to allow the guard to be pressed aside,-as shown .in red outline in Fig. 3, far enough to uncover the mouths of the chambers 'as they are severally brought by the revolution of the cylinder to the position of. that marked b:- viz., directly at the right of the axis of the cylinder, which is the position for-loading, and which allows the cartridge to be inserted past the right side of the front portion of the frame; v I

It will be seen by reference to Fig. 3 that the portion of the guard on the last-mentioned side i of its opening iis narrower than that on the opposite to permit its movement to be made in the proper direction from its central position, (shown in that figure in black outline,)1n which 2 areas .of the frame, in front of the guard, parallel, or

nearly so, with'the axis of the cylinder, and opposite to the chamber, in the position ot'th t marked b, is pushed back by the thumb apd finger against the bevel f with sufficient f0 cc to overcome the pressure of the springd, 1d so push aside the guard far enough to uncover the said chamber and allow thecartridge to enter, and the cartridge may then be pushed back into the chamber. When the cartridge has been pushed home the guard is pressed back by the spring at to the position shown in Figs. 3 and 4. When the discharged shell or cartridge is to be withdrawn from the chamber the guard is pushed aside far enough to uncover the mouth of the ehainberby the pressure of the thumb applied to iton the-loading side. The guard 0 might be so constructed that the portion on the loading side only shall be movable.

E, Fig. 1, is the ejector forejecting the-discharged cartrid ge-shells or the cartridges from thechambers; This is made in the form of ahammer, and arrangedto operatein the are or" a circle on the right-handior loading side of the frame A, behind'the cylinder, where itis pivoted by a screw, ,-.to the lower part of the frame. To allow this ejector to be used the cylinder has an opening, h, Fig. 2, provided in the rear of each chamber, into which the nose or point Kof the ejector can enter and pass to push the eartridge-shell or cartridge far enough forward from the chamber to enableits front end part to 1 be laid-hold of in front of the cylinder by the thumb andlfingerand thereby drawn out. The opening it is the same through which the hammer-F strikes to/explode the..fulmina,te in the cartridge. The aid ejector is so arranged that its point or nose K may enter the chambers as jection on the frame A, as shown in Fig. 1 in black outline, out of the way of the cylinder,

at all times but when it is desired to expel the cartridges or shells from the chambers. When the chambers are brought to the position of b, before mentioned, the ejector maybe pressed "forward by the thumb to the position shown in red outline in Fig. 1, and its nose, entering the opposite chamber, pushes forward the cartridge-shell or cartridge from the said oh amber.

F' is the hammer. made with a nose, m, of pointed or other suitable i'orm,to enter theopenin gs h provided in the cylinder coin m nnicatin g with the several chambers near the centers or aXee ofth'e bores thereof, and having its center of ,motion a s0 arranged as to permit the said nose to strike in a forward dire tion into the said openings, as shown in Fig. 2, when the chambers are severally brought into line with thebarrel for firing. By this construction and arrangement of the hammer, in combination with suitable openings, h, in the rear of the chambers of the cylinders, I am enabled'to use fixed-ammunitioncartridges, made with what is termed a central fire-'that is to say, having the fulniinate arranged in the centers of theirbottoms, without the interposition ofa pin between the hammer and the'cartridges-thns enabling central-fire cartridges to be used in a revolver'of a simpler constructionthan any in which such cartridges have been heretofore used. The cartridges are sup.- ported against the forward blow of the hammer by having the shells made ofalength equal to the full length of the chambers, so that their front ends will bear against the rear end of the barrel.

What I claim as-my invention, and desire to secure by Letters Patent, is-

1. The cartridge-guard O, constructed, applied, and operating under the control of a spring, d, substantially as herein specified.

\ 2. The ejector E, arranged to operate in the are of a circle in rear of the cylinder, on one side of the frame of a revolving fire-arm, and operating substantially as hereinset forth.

EB'EN T. STARR.
