Definitions

  • the invention relates to firearm arrangements and to hammer assemblies therefor.
  • US-A-3,016,646 discloses a removable hammer assembly for a pistol according to the preamble of claims 1 and 6 which assembly includes a hammer, a spring for biasing the hammer to the firing position and a sear for retaining the hammer in a cocked position.
  • a disconnector is provided for disabling the trigger of the pistol when the slide is retracted.
  • the hammer assembly is insertable into the firearm by means of a vertical slide and is locked in place by means of the slider.
  • the pistol comprises a safety mechanism
  • this is mounted on the pistol frame and not on the hammer assembly and is arranged to act directly on the trigger mechanism.
  • significant parts of the firearm mechanism are not readily removable from the firearm.
  • US-A-3,713,241 discloses a pistol having a removable hammer assembly, the assembly being removable by rotation thereof relative to the pistol frame.
  • the hammer assembly includes a hammer, a hammer spring, a sear and for cooperating with the hammer in conventional manner.
  • the assembly includes an ejector element. However, no disconnector or safety mechanism is mounted on the hammer assembly.
  • DE-C-90,430 discloses a pistol having a removable hammer assembly although removal of the assembly is not a simple operation and it is not intended that this be performed by the user.
  • the assembly comprises a hammer, a hammer bias spring and a safety mechanism, but no sear coupling the trigger to the hammer and arranged to hold the hammer in a cocked position.
  • An object of the invention is to provide a firearm of the type having a modular hammer assembly including a sear with an improved safety mechanism which is readily removable from the firearm, and another object is to provide a hammer assembly for such a firearm.
  • a firearm arrangement comprising a frame assembly, a modular hammer assembly, a slider assembly carrying a firing pin, a safety means and a barrel assembly, said hammer assembly comprising:
  • a hammer assembly comprising:
  • the illustrative hammer and safety assembly 2 is disposed in a pistol including a frame assembly 4 having as portions thereof a trigger guard 6, a trigger mechanism 8, a grip portion 10, and a barrel mounting portion 12.
  • the pistol further includes a barrel assembly 14 connectable to the barrel mounting portion 12 and a slide receiver 16 slidably received by and mountable on the frame assembly.
  • the modular hammer and safety assembly 2 includes a housing 20 having extending therefrom a slide means (22 (Figs. 9, 11) adapted to interconnect with a slide means 25 on the frame assembly 4 for sliding interconnection with slide means 23 of the slide receiver 16 (Figs. 7, 8), the slide receiver thereby locking the hammer and safety assembly 2 in place in the frame assembly 4.
  • the hammer and safety assembly 2 is inserted in the frame assembly 4 such that the respective hammer and safety, and frame, slide means are aligned.
  • the slide member 16 is then slid onto the combined frame and hammer and safety assemblies by sliding engagement of the slide means 23 with the aligned slide means.
  • the slide receiver 16 locks together the frame and hammer and safety assemblies 4, 2.
  • a hammer 26 is pivotally mounted in the housing 20 by a pin 28 disposed centrally of a pawl portion 30 of the hammer 26.
  • the pawl portion 30 is provided with teeth 32 on a portion of its periphery.
  • a spring 34 is mounted on a pin 36 in the housing 20 and extends into a recess 38 in the hammer 26. The spring 34 biases the hammer forwardly, or leftwardly as viewed in Fig. 1.
  • a sear 40 is pivotally mounted in the housing 20 by a pin 42.
  • a first end 44 of the sear 40 is adapted to engage the teeth 32 of the hammer pawl portion 30; a second end 45 of the sear 40 is adapted to be engaged by the trigger mechanism 8.
  • the sear 40 interconnects the trigger mechanism 8 and the hammer 26.
  • a disconnector means 46 is disposed in the housing 20 and comprises a pin 48 slidably disposed in a bore 50 in the housing 20.
  • the pin 48 at a first end 52 thereof is engageable with the slide receiver 16, and at a second end 54 thereof carries a pusher member 56 operable to divert movement of the trigger mechanism 8 during a cocking operation, as will be further explained below.
  • a safety means 60 is mounted in the housing 20 and includes a reciprocally moveable plunger 62 engageable with the sear 40 to separate the sear and the hammer pawl portion, releasing the hammer but shielding a firing pin 63, as will be further discussed below.
  • the plunger 62 has a slot 64 therein in which is disposed a pin 66, the slot and pin arrangement permitting movement of the plunger selectively toward and away from the sear 40.
  • An actuating lever 68 (Fig. 12) may be located on the side of the slide receiver 16 and be operatively connected to the plunger, as by a rotatable cam means 69, to serve as an actuator for the safety plunger. As shown in Figs. 3 and 8, it is preferable that an actuating lever 68 be disposed on each side of the slide receiver 16 to facilitate manipulation by either hand of an operator.
  • Figs. 1 and 2 the firearm is shown at rest, with the safety in the inactive, or raised, position.
  • the hammer 26 is in a forward position, biased forwardly by the spring 34.
  • the first end 52 of the disconnector pin 48 is disposed in a recess 70 in the slide receiver 16.
  • the slide receiver is moved rearwardly by an operator to the position shown in Figs. 4 and 12.
  • Fig. 4 it will be seen that the rearward movement of the slide receiver 16 has forced the disconnector pin 48 out of the recess 70 and downwardly, causing the pusher member 56 at the second end 54 of the disconnector pin 48 to bear against the trigger mechanism 8, pushing the trigger mechanism downwardly and out of alignment with the sear 40.
  • pressure applied to the trigger by the operator will fail to actuate the hammer.
  • the rearward movement of the slide receiver 16 relative to the hammer and safety assembly 2 has further caused the hammer to pivot upon pin 28, against the bias of the spring 34 to the position shown in Figs. 4 and 12.
  • the toothed portion 32 of the pawl portion 30 of the hammer has been engaged by the first end 44 of the sear 40, holding the hammer in a rearward position, as shown.
  • a leaf spring 74 extending from the frame assembly 4 bears against the sear 40 and exercises a steadying and holding influence thereon.
  • the actuator lever 68 may be rotated to move the safety plunger 62 into abutting engagement with the sear 40, separating the sear from the pawl portion 30 of the hammer 26, thereby releasing the hammer and permitting the hammer to pivot forwardly under the influence of the spring 34 (Fig. 7).
  • Turning the safety actuating lever 68 serves to rotate the cam means 69, as aforementioned, which serves to move cam stop means 76 into a position protecting the firing pin 63 from contact by the hammer 26 (Fig. 7).
  • the actuation of the safety causes the hammer to move forwardly, but prevents the hammer from striking the firing pin. To fire the pistol, it is necessary to release the safety and re-cock the pistol.
  • the required interchange components are removed from the frame assembly and new components are attached thereto.
  • the slide receiver 16 is then removed by sliding forwardly, or leftwardly as viewed in the drawings.
  • the hammer and safety assembly 2 is then removed from the frame by lifing upwardly.
  • a "new" hammer and safety assembly, slide receiver, and barrel assembly are attached, as above described, to the frame 4.
  • the entire hammer and safety assembly is removable and insertable as a single unit.
