` UNITED STATES PATENT fOEEICE.

VILLIAMMASON, OF HARTFORD, CONNECTICUT, ASSIGNOR TO THE OOLTS PATENT FIRE-ARMS MANUFACTURING COMPANY, OF SAME PLACE.

REVOLVER.

.SPECIFICATION forming part of Letters Patent No. 249,649, dated Novemberl, 1881.

Application filed July 25, 1881. (No model.)

To all whom it may concer-n:

Be it known that I, WVM. MASON, ot' Hartford, in the county ot' Hartford and State ot' Connecticut, have invented new Improvements in Revolvers; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters ot' ret'- erence marked thereon, to be a full, clear, and exactV description of the. same, and which said 1o drawings constitute part oi'this specitication,

and represent, in

'Figiire 1, a sectional side view; Fig. 2, a transverse sectional view, showin g the first or transverse swinging movement; Fig. 3, a top 'sectional view, showing the last or forward movement.

This invention relatesto an improvement in. revolvers, with special reference to that class in which the cylinder is hung in its recess in 2o the frame, so that it maybe turned to one side sufficiently far to present the chambers ot the cylinder outside the frame for theinsertion or removal of the cartridges or shells, as the case may be, the object being to combine with the mechanism which permits such movement ot" the cylinder au ejecting device which will be V Operated by thc swinging movement ofthe cylinder to eject the cartridge-shells, and so that the person holding the revolver may, by 3o a quick twist of his hand, cause the cylinder y to move out from its place in' the frame, and when it has arrived at a point so far outside the cylinder that the heads of the shells are exposed the continued and 'completing out- 5 ward or swinging movement of the cylinder will operate upon the ejector to torce the shells from their respective chambers.

The invention consists in the arrangement.

of a frame forward of the cylinder-opening, to

4o swing outward upon a pivot or pivot-piece below the cylinder-opening, theaxis of said pivot substantially parallel with the axis of the cylinder and provided with a'centenpin, on which the cylinder revolves, the said swinging part ot the frame hinged to the pivot, so that after the cylinder has, with the said swinging part, been swung outward in a plane at right angles Y to Athe frame until the cylinder is substantially free from its recess, it will then, turning onthc said hin ge, swing forward in a plane parallel 5o with its axis, combined with an ejector operated during this latter or forward swinging movement to force the shells from their place in the cylinder.

A represents the frame, of substantially the 5 5 usual outline, with a recess, B, for the cylinder, and provided with the barrel C and the usual lock mechanism for successively' presenting the chambers of the cylinder into line with the ,barrel and discharging the cartridges presented 6o by such chambers in substantially the usual manner. y

D is the cylinder, ot' substantially the usual form.

In thc frame below the cylinder is a spindle or pivot-piec'e, E, the axis ot' which is substantial] y parallel with the axis of the cylinder, but so that it may be rotated in its place inthe frame, as hereinafterdescribed. To the forward end of this pivot E a part, E, of the frame is 7o hinged, as at c. This part E ts into a corresponding recess made on the inside of the frame A forward of the cylinder-opening, as seen in Fig. l, and in broken lines, Fig. 2. The said part E has the center-pin 'E2 attached to 75 or made a part of it, the axis of which, when in place, as seen in Fig'. 1, is substantially parallel with the axis ofthe pivot E. On this center-pin the cylinder Dis arranged so as to be rotated in the usual manner. Thus arranged, 8o the part E and the cylinder upon its centerpin may be turned from the frame, swinging ou the pivot E yas the center, and in a path at right angles to the frame or axis of the cylinder, until the cylinder is clear from the frame, as seen in broken lines, Fig. 2. Thenthe part E of the cylinder may be turned forward on the hinge between the part E and the pivot E on a plane parallel with the axis of the centerpin, as seen in Fig. 3, which brings the cyl- 9o inder to a position inclined to the frame, as shown in the said Fig. 3. Under this arrangement of the parts, it' the person holding therevolver giveit a quick twist to the right, it will cause the cylinder-and the part E to quickly 9 5 swing out from the fra-mc, as in Fig. 2, turnin g on the pivot E as its center until its movement in that direction is arrcstcdby a shoulder, a, on the pivot part coming against a corresponding shoulder, a', on the frame or stationary part, (or other suitable s top,) which occurs, as seen in Fig. 2, when the cylinder is free from frame. Theil the force given to it by the twisting motion before mentioned will cause the cylinder and part E to turn forward upon the hinge e, as from tlrgposition in broken lines, Fig. 2, `to the position `shown in solid lines, Fig. 3, until such forward movement is arrested by a shoulder, Z, on the swinging part striking a corresponding shoulder, b', on the pivot part, or other suitable stop. A reverse twisting movement-that is, a twist to the left-` will return the cylinder to its place. I have said the twist is to the right for opening and' left for closing but it will be understood that the` arm may be made for the cylinder to move initheopposite direction, in which casey the twisting' movement will be reversed.

The ejector isof that character well known asthe-star ejectoi--that is to say, a starshapedplate, F, arrangedin a recess at the rear end ofthe cylinder, or so that partsof it will'lie beneath the flange of the several cartr-idges whenl in place in the cylinder, and so that-a reverse movementof the said plate, as' fronrthe position in Fig. 1 to that in Fig. 2, will force the several cartridges or shells simultaneously outward from their respective chambers. As here represented, the ejector-plate Fisi-attached to an ejector-rodhF, arranged through the 4rear end of the cylinder and into thecenter-pin, the said center-pin made hollow or tubular to receive the said ejectorrod.`

In the swinging pant E is a follower, j', arranged longitudinally and so asto bear against the forward end of the ejector-rod, and so that themovementof thesaid followerrearward will correspondingly move the ejector rearward, a-s from-theposition in Fig. I to that in Fig. 3.A

` To automatically' operate the ejector, anarm, H,is2 attached to or made a part of the pivot E, a'ndlies ina recess in theswinging part E in la plane substantially parallel with the axisof theejectorrod and the follower f. This arm, being stationary upon the pivot, turns with the pivot. and the swinging part in the rst movement, as from the position in Fig. 2

to Athat shown in broken lines, same figure 5 but inthe last or forward part of the swinging movement theswinging part E turns upon its hinge independent of said arm, and so that the said arm H, remaining stationary, is broughtfrom the positionaway from the cylinder in.Fig. 1 to the position near the cylinder, as in Fig. 3. The upper end of the arm H is in connection with the follower f, as seen in Figsi-l and 3. Hence during the last or for. ward swinging movement, the follower will remain stationary with thearm H, as will the ejector, which will cause the swinging part andcylinder to slide forward. on the ejectorrod, as from the position in broken lines, Figi. 3, to that seen in solid lines, same figure, and

which produces practically the rear or eject-in g movement of the ejector-plate.- Hence by the twisting movement given to the arm, as before referred to, the ejector withdraws the shells fromthe cylinder, and thereverse swinging movement, which returns the cylinder first from the position seen in Fig. 3, solid lines, to that seen in broken lines, same figure, will return the ejector to its place, and finally the cylinder and the parts thereto connected to their place of rest in the frame.

The follower may be connected directly to or made a part of the ejector-rol; but I prefer to make the follower in a separate piece from the ejector, so that it will not rotate with or interfere-with the rotation of the ejector-rod, wlich must turn with the cylinder.

In case the ejector-rod is extended so as to engage directly with the arm H, that engage-l would work. If the ejector-rod be made separate from the follower, then it is necessaryto provide means to automatically return the ejector during the return of the swinging part. To do this I introduce through the ejector-rod a spindle, I, having a head, 1', at its rear-'corresponding to the internal diameter of the h`ollow ejector-rod. This spindle is introduced through the ejector at the rear and made fast to the swinging part at the front by a nut, l2, or otherwise. -v t Around't-he spindle I, within the ejector-rod, is a spring, L, which bears against the head I of the spindle at the rear, and at its forward end against a seatv in the ejector-rod, so that as the ejector is thrown outward-. or, `which is the same thing, the cylinder forwardthe t spring is compressed between itsseat iu the rod and the. headl I ,of the spindle, as'seen in. Fig. 3. Hence, if the follower be not connected directly to the ejector-rod, the spring will serve to return the ejector, as the follower vpermits it-to do in the closing movement of the swinging part. This arran gement'of the hollow ejector-rod, spindle,and follower, as well as the mechanism .shown in Fig. 1 for locking the swinging' part in place, is the same as that shown in an application forLetters Patent which 1 have led on even date herewith, designated as GaseB',7 and requires no further description in this application than to say that a locking mechanism must be provided which will secure the cylinder-and swinging part in place, and such locking mechanism should be such that the person holding thefpistol may, by his thumb or finger, disen gage that locking mechanism, so as to be able to throw the cylinder out of and into place,

l as before described, without applying the hand directly thereto. The thumb piece or lever by which he is enabled to do this is shown at u', Fig.- 1,'and is the same as that shown in my application before referred to. I claim- 1. In 'a revolver, the swinging part E', hav- 'Y upon the hinge which connects it to said piv=V ing thecenter-pin on which the cylinder re:-

voives attached thereto or made apart of itV and hinged toa pivot-piece in the frame below `the cylinder-opening, the axis of said pivotpiece substantially parallel with the said center-pin, and so that the said swinging part, with the cylinder, will swing outward from its place in the frame, turning upon the said pivot-piece as its center of motion and in a plane at right angles to the axis of the cylinder, and when the cylinder shall have passed from its recess in the frame it will then turn forward ots-piece in a'plane parallel with the axis ot" said pivotpiece, combined with an ejector arranged through the center-pin for longitudinal movement, and mechanism substantially such as described, to engage said ejector during the forward swinging movement of the cylinder and impart to the said ejectora rear movement, substantially as described.

2. In a revolver, the swinging part E', hav- =n'g the center-pin on which the cylinder revolves attached. thereto or made a part of it and hinged to a pivot-piece in the frame below the cylinder-opening, the axis of said pivotniece substantially parallel with the said center'pin, and so that the said swinging part, with the cylinder, will swing outward from its place in the frame, turning upon the said pivot-piece as its center of motion and 4in a plane at right angles to the axis of the cylinder, and when the cylinder shall have passed from its recess in the frame it will then turn forward upon the hinge which'connects it to said pivot-piece in a plane parallel with thc axis of said pivot-piece., combined with an arm rigidly attached 'to the said pivot-piece, arranged t0 turnwith the cylinder in its first or outward swinging movement, but stationary in the last or forward swinging movement of the cylinder, an ejector arranged through said cylinder ,for longitudinal movement, and a follower in the swinging part forward of said rod, with 'which said arm will engage to impart a rear movement to the said ejector during the last or forward swinging movement ofthe cylinder, substantially as described.'

3. In a revolver, the swinging part E', having the centerpin on which the cylinder revolves attached thereto or made a part ofit and hinged to a pivot-piece in a frame below the cylinder-opening, the axis ot' said'pivotpiece substantially parallel/with the said center-pin, and so that the saidfswinging part, with the cylinder, will swing outward from its place in the frame, turning upon the said pivot-piece as its center of motion and in aplane at right angles to the axis ofthe cylinder, and when the cylinder shall have passed from its `recess in the/frame it will then turn forward upon the hinge which connects it to said pivot-piece in a plane parallel with the axis of said pivot-piece, combined with an arm rigidly attached to the said pivotpiece, arranged to turn with the cylinderin its first or outward swinging movement, but stationaryin the last or forward swinging movementof the cylinder, an ejector arranged through said cylinder for longitudinal movement, and a follower in the swinging part forward ot' said rod7 with which said arm will engage to impart a rear movement te said ejector during the last or forward swinging movementof the cylinder, and a spring within the rod operating to draw the ejector to its place in the cylinder, sub` stantially as described.
