Definitions

  • My invention relates to that class of firearms in which a series of parallel chambers for containing the charges are made in a rotating breech, so placed in connection with the barrel that by the rotation of the said breech the charges are in succession brought in aline with the barrel for discharge.
  • the principle or mode of operation which distinguishes my invention from allother things before known consists, first, in combining the rotating breech with the lock in such manner that by operating the cock the breech shall be rotated to bring the charges in succession to the line of the barrel for the discharge second, in combining the rotating chambered breech with thelock by means of a catch orits equivalents in such manner that by the operation of cocking the said rotating breech shall be liberated to admit of being turned, and when turned relocked to hold the particular.
  • Division 1 of the drawings represents a pistol.
  • Division 2 represents Division 1 in four sections, as 1, 2, 3, and 4.
  • Division 3 represents all the parts in Section 1 of Division 2.
  • 0 represents the hole which-re ceives the lower arm of the lifter that turns the cylinder.
  • d represents the part of the hammer where the mainspring acts upon it.
  • e is a projection by which the hammer is drawn back.
  • Fig. 2 is the mainspring.
  • Fig. 3 is the key-hole or catch-lever that holds the cylinder in its place by the arm a when each chamber is brought opposite the barrel.
  • b is a spring, which is attached to the part-c, which has a lateral motion to the right by means of a hinge at d, and serves to allow the pin b in Fig. 1 to pass it.
  • the fulcrum of the key-bolt or catch-lever is ate.
  • f is the fulcrumpin.
  • 9 is the spring which forces the key into the wards of the cylinder.
  • Fig. 4 is the lifter or hand, with thespring on the left side to allow it to move laterally to the left when acted on at a by each tooth of the ratchet.
  • At b is ajoint which connects it with the pin 0, which acts in the hole 0, in Fig. 1.
  • Fig. 5 is the connecting-rod.
  • the end a serves as a scar or catch to the hammer when the lock is set, and when the hammer is pulled back the rod moves forward horizontally in consequence of the hammers coming in contact with it, and the end b operates upon the trigger, Fig. 6, at the catch a, and throws down the end I), by which means the claw 0 hooks into the end b of Fig. 5, and is held in its place by the spring, Fig; 7, acting upon it at the pin 01.
  • Fig. 8 is the pin which holds in their places the spring, Fig. 7, at a, and the connectingrod, Fig. 5, at c. Fig. 6moves on the pincatf.
  • Fig. 9 is a spring which holds the rod, Fig. 5, toward the hammer, that the connecting-rod may catch in a notch at the bottom of the hammer to hold it when set.
  • Fig. 5 is the ratchet, which is placed in the middle-of the shield, at a, and receives the shackle, to which it is connected by the tongue or projection b.
  • the arbor is prevented from turning in the-shield by means of .pin or key in the shield, which enters the groove d on the arbor.
  • Fig. 2 Section 3 of Division ,2, represents the fore part of the cylinder.
  • cc, &c. represent the wards to receive the en d a of the key, bolt, or catch-lever, Fig.'3, Division 3, to prevent the cylinder from turnmg when a charge is brought opposite the barre b b, &c., Fig. 1, represent the tubes or nipples, on which are placed the percussion-caps.
  • c 0, Spa are partitions which prevent the commun catiou of fire or. smoke froln one cap to another.
  • Section 4 0 represents the hole through which the arbor passes, and b a mortwo for the key 0. to connect this section with the arbor.
  • the ball enters the barrel from thechamber.
  • the barrel is fastened to the plate.
  • At f is a-groove in the plate to recelve the end aof the lock-plate of Section 1, which serves to steady it.
  • 9 represents the bayonet, hung on a pin at h, t beinga catch to hold it in its place when it is thrown out.
  • the hammer is hung at thel'ulcram a.
  • a The key, belt, or catch-lever which holds the cylinder is hung at the fulcrum b.
  • the lifter that works the ratchet has a working connection with the hammer on the left side at o.
  • the arm d of the lifter works into the teeth of the ratchet on the left.
  • e represents the ratchet when connected with the shackle.
  • f f is the middle and forward part of the shackle on which the ratchet is placed.
  • 9 is the arboron which the cylinder revolves. The end his the nut that holds the pin in its place when in the shield.
  • the pin 12 By drawmg back the hammer the pin 12 operates upon the after end of the key, bolt, or catch-lever that locks the cylinder and raises it. Consequently the other end,r, is drawn from the cylinder, and the arm d of the lifter commences to act .on a tooth, s, on the left sided the ratchet, which, being connected to the cylinder by means of theshaekle,turns it until the next chamber is brought opposite to the barrel.
  • the pin p When the pin p is relieved from the key by passing over its upper end,t, the pin allows the end 1' of the key to be forced, by means of the spring m, into the succeeding ward of the cylinder.
  • Plate 2 represents the principle of the invention as applicable to rifles, muskets, and other fire-arms differing from what has already been described, first, in the manner of setting the lock secondly, in the use of an adopter for communicating the forceof the hammerto the percussion-cap; thirdly, inthe situation of the main-spring and trigger; and, fourthly, in the construction of the lock-plate and guards that hold the stock.
  • Fig. 1 represents the mainspring.
  • Fig. 2 is the stirrup to connect the mainspring with the hammer-
  • Fig.3 is the hammer;
  • Fig. 4 is a secondary lever for setting the lock.
  • Fig. 5 is the discharging-trigger.
  • Fig. 6 is the adopter.
  • Fig. 7 is the spiral spring to drawback the adopter.
  • Fig. 8 represents all the parts combined.
  • the fulcrum of the secondary lever being at a, by drawing down on the end b the end a operates upon the end d of the hammer, whose fulcrum, being at e, throws back its end f, when the trigger at 9 (whose fulcrum is at h) operates upon the catches of the hammer at i to hold the lock when set.
  • the end f of the hammer is removed from the adopter (whose bearings are at j 9') it is drawn back by means of the coiled spring in until'its end I is drawn back suflicient to allow the cylinder to turn, which is efl'ected as de scribed in the pistol.
  • the parts of my invention may be variously modified.
  • the ratchet-teeth by which the chambered breech is turned on a separate piece and connecting it with the breech by a shackle
  • the ratchetteeth, or the equivalent thereof may be made directly on a projection of the breech, or in the end thereof, or in a cavity therein, or on any partconnected with the breech, as convenience may dictate.
  • the lifter or hand that turns the chambered breech may be connected therewith by an intermediate lever or levers, or by an intermediate link, and the secondary lever may be used for operating the hammer, and instead of turning the breech by the upward motion of the lifter this may be reversed.
