Definitions

  • the present invention relates generally to firearms, and more specifically, to revolvers provided with cylinders which are quickly and easily removed.
  • the semi-automatic pistol is loaded with a clip-type of magazine. This magazine holds more rounds of ammunition than the cylinder of the typical revolver and is easier to load.
  • the semi-automatic may be "single action” or “double action”.
  • the "single-action” semi-automatic has an exterior safety device, which must be released in order to operate the weapon. When locked, the hammer and magazine of the "single-action" semi-automatic are under constant compression. As a result, the long term reliability of this weapon is decreased, and additional maintenance and repair are required. Moreover, .the "double-action" semi-automatic requires a greater trigger pressure for the first round than for succeeding rounds.
  • the revolver is simpler than the semi-automatic pistol.
  • the revolver mechanisms are unstressed when not in use.
  • the revolver is easy to operate and maintain, and is less prone to accidental discharge and jamming, than the semi-automatic pistol.
  • the revolver is preferred to the semi-automatic by most law enforcement agencies.
  • a major disadvantage of the revolver is the length of time needed for reloading. This disadvantage has been partially alleviated by the development of the "speed loader."
  • the commercially available speed loader maintains a full reload of fresh cartridges in an arrangement which conforms to the configuration of the cylinder bore. The speed loader thereby allows a full complement of cartridges to be loaded simultaneously, rather than individually.
  • replaceable cylinders have been mounted to the revolver frame by means of a pivot or linkage. These pivoted mechanisims may fail after a period of time due to the relatively-high impact loads incurred during firing of the revolver. Additionally, in the known prior art, the ejection and replacement means for such cylinders are cumbersone and require additional manual operations to reload.
  • a revolver includes a frame having a completely removable cylinder therein.
  • the cylinder is adapted to be easily replaced with a second fully- loaded cylinder.
  • a retention means maintains the cylinder within the frame and has an engaged and a disengaged position.
  • a first resilient means maintains the retention means in its engaged position, thereby maintaining the cylinder in the frame.
  • a manually-operable release means opposes the first resilient means for selectively moving the retention means into its disengaged position.
  • one or more resilient means automatically eject the cylinder completely from the frame. In this manner, a revolver can be reloaded quickly by ejecting the first cylinder from the frame and inserting the second cylinder therein, without the necessity for looking at the revolver.
  • a revolver R has a frame F for receiving a removable cylinder 20.
  • the removable cylinder 20 has longitudinal bores 21 for receiving cartridges C, one of which is shown in broken lines in Figure 10.
  • the cylinder also has a central bore 23 having an expanded portion 24.
  • a shaft 22 is loosely received within the central bore, such that the --cylinder may rotate freely about the shaft.
  • the rear end face of the cylinder is reduced to form a collar 30.
  • An anti-friction device such as a roller bearing 27, is press-fitted on the collar.
  • a rear face of the collar 30 has a ratchet plate 31, shown more clearly in Figure 4, having a series of ramps 32 concentrically of the central bore. The ramps 32 provide the advancing means, so that the cartridge bores 21 are brought into firing position, in series, as the trigger is pulled.
  • a tapered rear portion 28 of the shaft protrudes from the rear face of the cylinder and is received in a complemental rear pilot bore 29, as shown more clearly in Figures 1 and 10.
  • the forward end face of the cylinder is also reduced to form a forward collar 33.
  • An anti-friction device such as a roller bearing 34, is press-fitted on the collar 33.
  • the forward end of the central bore in the cylinder has a tapered counterbore 49 concentrically of collar 33. This tapered counterbore forms a forward pilot bore for receiving a complementary spring-loaded tapered centering pin 35.
  • the frame of the revolver has a centering pin cavity 37, as shown more clearly in Figure 1.
  • a spring 38 is received in the cavity and urges the centering pin 35 rearwardly.
  • the centering pin is received within a tapered counterbore 49 in the cylinder, thereby displacing the shaft 22 rearwardly.
  • the tapered rear portion 28 of the shaft is received within the pilot bore 29 in the revolver frame, as shown in Figure 1.
  • the cylinder 20 is seated in the revolver frame and is retained in a first operative mode, which permits only rotational motion of the cylinder, and the revolver is ready for firing.
  • the various cylinder bores 21 are alternately aligned with the barrel of the revolver, and the cartidges in the barrel may be sequentially discharged in the usual manner.
  • a forward guide channel 39 (shown in Figure 3) and a rear guide channel 40 (shown in Figure 2) are formed in the revolver frame.
  • the rear guide channel 40 is defined by shoulders 41 which taper or converge inwardly of the revolver frame.
  • This ramping surface 42 contacts and gradually depresses the shaft 22 during installation of the cylinder 20 within the revolver frame.
  • the shoulders 41 engage and direct the outer surface of the roller bearing 27, thereby guiding the cylinder until the roller bearing 27 is substantially aligned with the rear pilot bore 29. At that point, the tapered rear end portion 28 of the shaft 22 "snaps" into engagement with the rear pilot bore 29.
  • the cylinder is then in its seated and operational position.
  • the forward guide channel 39 within the revolver frame has an inclined ramping surface 43 with shoulders 44 to guide the forward portion of the cylinder 20 into its seated operational position.
  • the bearing 34 engages an inclined actuation ramp 45.
  • This ramp 45 protrudes through an opening 45A in the forward guide channel 39, as shown in Figures 7 and 9, thereby depressing the spring loaded ramp.
  • the ramp is formed integrally with centering pin 35, and the centering pin 35 is withdrawn within the confines of the cavity 37 (as shown more clearly in Figure 8).
  • the centering pin 25 When advanced beyond this point and into the operational position, the centering pin 25 once again returns to its fully extended position, seating itself within the tapered counterbore 49 as shown in Figure 9.
  • the stops 5 and 3 have surfaces 2 and 48, respectively, which are complementally formed to receive and match with the outer surface of the cylindrical roller bearings 27 and 34.
  • the respective bore 21 is directly aligned at its front end with the barrel B ( Figure 3) and with the firing pin P ( Figure 2) at its the rear end.
  • the ejection lever 9 is pressed forwardly. This rotates a pivot shaft 8 which carries an actuation lever 7.
  • the actuation lever pushes an ejection shaft 6 forwardly in the revolver frame, and the ejection shaft displaces the cylinder shaft 22 forwardly until the rear portion of the shaft 22 is flush with the ratchet plate 30.
  • the shaft and the cylinder carried thereby are released from the means which retains the cylinder within the revolver frame.
  • the rear stop 5 and the forward stop 3 spaced from one another, automatically eject the cylinder 20 from the revolver frame.
  • stops 5 and 3 are constantly urged by resilient means 4 and 4a, respectively, from a first retracted position in which the cylinder 20 is in its seated operational mode within the revolver frame (ready for firing of the revolver) into a second extended position in which the cylinder is automatically ejected from the revolver frame.
  • Spring clips 47 are provided to retain the cartridges within the cylinder thereby retaining the cartridges even if the cylinder is inverted.
  • each spring clip 47 is-substantially V-shaped and-is snapped within a closed pocket 47a communicating with the bore 21 for the cartridge C. The apex of the V is received in the annular groove 47b formed in the cartridge C near the annular rim at the base of the cartridge.
  • the revolver may be provided with at least two cylinders 20.
  • the first cylinder may be removed quickly and easily by simply pressing the ejection lever 9 forwardly.
  • the stops 3 and 5 then thrust outwardly laterally of the revolver frame, thereby automatically ejecting the first cylinder from the revolver frame.
  • a second fully-loaded cylinder 20 may be quickly and easily "snapped" into the revolver frame. This is accomplished by aligning the guide channels 39 and 40, respectively, and pressing the second cylinder inwardly until the stops 3 and 5 are depressed.
  • the tapered end 28 (of the cylinder shaft 22) and the tapered centering pin 35 are seated in tapered bores 29 and 49, respectively, to seat the second cylinder within the revolver frame in its operational position, such that the revolver is again ready for firing.
  • a third cylinder may be employed if desired.
  • a series of preloaded cylinders may be carried on a utility belt, for example, and snapped into the revolver frame (as needed) to provide for quick and efficient reloading.
