Similar letters of reference indicate corresponding parts in the several figures.
This invention, which, to' distinguish it from Aseveral other of my improvements in rire-arms,
I will'denominate No 4, relates to tire-arms having the rotating man y-chambered cylinder.
It consists, tirst,vin extending the chambers through the rear of the cylinder for the purpose of loading them at the breech from beliind, either by hand or by a self-actin g charger, from a magazine placed in rear of the cylinder.
It consists, secondly, in a guard so applied in front of the chambered cylinder as to receive or stop the balls, but to allow the escape ofthe exploded powder if the charge in any of the chambers not in line with the barrel should be exploded by lateral fire or any accident.
It consists, thirdly, in the combination of a charging-piston with the hammer in such a way` that by the drawing back or raising of the hammer to cock the lock the said piston is caused to ,drive a cartridge into one of 'the chambers .from a magazine placed behind it. This improvementis applicable to other kinds of breech-loadin g fire-arms besides those employing a rotating chambered cylinder.
It consists, fourthly, in an attachment to the hammer for the purpose of closing the magazine perfectly during the discharge of the piece escape of powder.
to protect the charges in the magazine from the eiects of lateral tire.
A. is the rotating chainbered cylinder, having the chambers a a bored right. through it, and made slightly conical, with the smallest, part in front, in order that a cartridge maybe inserted easily at the back, but that the ball may tit tight when it arrives in its place n nd not go through till the charge explodes.
a is the pill upon which the. breech rotates, the rotation being effected, in a way not necessary to be here explained, by a tooth attached to the trigger. i
L (see Fig. 4) is arecess made in the side of the stock M, to dord. suicient room in rear of the cylinder, ojiposite one ot' the. chambers a a, for the insertion ot' a charge by band at the rear opening o the said chamber.
p, Fig. l, is a fixe-d breech-piece, arranged opposite the barrel, behind'the cylinder, reserve. as a breech to that chamber which happens to be inline with the barrel.
B is a guard for the purpose ot' receiving or stopping the balls in case of accidental explosion in any chamber not in'line with the bar- Figs. 1 and 2,) for the escape ot' the exploded powder in front ot' the cylinder, and to make a recess, e, (see Figs. l. -and 5,) in its face, into which the ball or balls from any or all ot' the chambers notin line withthe barrel may enterwhcn the charges explode, to allow the free The guard may, however. be made Without the above-named recess in its face, and may fit close to the front ot' the cylinder if a free escape for the exploded pow der is provided yfor by leaving suitable open space in the rear.
E is the magazine, vwhich consists of a box, in which the cartridges are laid side by side parallel with the bore of the barrel, to be forced one by onesidewise 'by a spring, q, or other means into the charging-tube F, which stands behind and in line with on` of the chambers ot' the cylinder. .The charging-piston G, which ts the tube F, is furnished. with a rack, f,
gearingwith a toothed wheel, g, (see Fig. 6,)
which is fast on the same spindle or arbor 7b as another toothed wheel, i, which gears with a third toothed wheehj, secured firmly to the tumbler bof the hammer l. The raising of the hammer to cock the lock gives the wheels j i g such a movement as to throw forward the piston G to-drive a cartridge which has been supplied to the tube from the magazine into the chamber ot' the cylinder with which it is in line. The falling ofthe hammer draws back the piston far 'enough' to allow another cartridge to enter the charging-tube from the magazine.
fm is the attachment to the hammer for the purpose ot" closing the mouth oi' the magazine during the discharge. This attachment is only shown in Fig. 6, being out away in Fig. l, which only shows the hammer proper'. It may be made all in one piece of metal with the hammer. y lts face a forms an arc concentric with the arbor or spindle 0 of the hammer, or very slightly eccentric thereto, and the exterior of' the moulh of the magazine is made of a corresponding; form, in order that they may tit close together. The face n may be covered with an elastic packing to close the mouth of the magazine more securely. As lthe hammer fails the attachment covers the mouth of the magazine before thev priming is exploded, and thus serves an eicient protecion to the magazine.
What l claim as my invention, and desire to secure by Letters Patent, is-
l. Extending the chambers a a of the rotating cylinder A right through the rear of` the said cylinder for the purpose of enabling the said chambers to be charged at the rear either by hand or by a sel'tacting charger, substani tially as described.
2. The application of a guard to cover the front of all the chambers of the cylinder which are not in line with the barrel, or any number thereof which may have been loaded, combined with the provision of a proper space for the lateral escape of the exploded powder, substantially as herein described, whether the said space be between the cylinder and guard or in rear of the cylinder, and whether the said guard be constructed vwith a recess, e, to receive the balls or be of such form as merely to stop the balls.
3. Combining a chargingpiston, G, with the hammer by means of gearing, substantially as described, or by the equivalent thereofin such a manner that by raising the hammer to cock the. lock the piston is moved toward the'chamhcred cylinder to force a cartridge from the magazine into one ot the chambers thereof, and by the falling of the hammer'the piston is 'withdrawn to allow a new cartridge to be sup plied, ready to be driven into the next chamy ber of the cylinder as the hammer is again raised to cock the piece, as herein fully set forth.
4. Furnishing the hammer with an'attachment, m., by whichvin the act of falling it may close the mouth of the magazine, substantially as herein described, before exploding the priming, and thus protect the charges within'the magazine from ignition.
