Definitions

  • the pistol of this invention incorporates a fire control group of an en bloc type removably mounted in a receiver and having a housing extremity engaging the receiver at a location remote from a hammer pivot axis, a slide reciprocably mounted on the receiver, and a barrel operated by the slide and having a downwardly projecting lug, the lug being received for limited captured movement in the frame between longitudinally spaced vertically offset limit positions, and a pair of camming pins longitudinally spaced apart in the receiver to extend laterally across the path of movement of the barrel lug and serving both to guide and stop barrel movement relative to the slide in timed relation to its movements.
  • This invention generally relates to firearms, particularly automatic pistols, and specifically concerns a socalled en bloc fire control group and a barrel guide and stop mechanism for a pistol of a type having a movable barrel operated by a slide.
  • a primary object of this invention is to provide a firearm having an improved en bloc fire control group which not only is self-locating in operative position in a receiver but is also self-restrained therein against undesired movement during trigger actuation and pivotal hammer movements.
  • Another object of this invention is to provide such an improved fire control group particularly suited for quick and easy mass production without close tolerance requirements while yet minimizing any free trigger travel.
  • a further object of this invention is to provide a pistol having a significantly improved barrel guide and stop mechanism for precisely engaging and disengaging a movable barrel relative to its operating slide in timed relation to the movements of the slide.
  • Still another object of this invention is to provide such a barrel guide and stop mechanism of a simplified construction which not only can be easily mass produced to critical tolerances at moderate cost, but is also of a rugged construction for reliable operation over an extensive service life.
  • a still further object of this invention is to provide an improved pistol having a fire control group and barrel guide and stop mechanism featuring a minimum number of compact parts in a relatively light hand gun having an all steel frame construction for large calibers and a high-capacity magazine.
  • FIG. I is a side view, partly broken away and partly in section, showing a preferred embodiment of a pistol incorporating this invention with the barrel guide and stop mechanism in a forward limit position;
  • FIG. 2 is a side view, partly broken away and partly in section, similar to FIG. 1, and showing the barrel guide and stop mechanism in a rear limit position;
  • FIG. 3 is a side view, partly broken away, showing an en bloc fire control housing
  • FIG. 4 is a side view, partly broken away, showing a portion of the receiver forming a pocket for the fire control housing;
  • FIG. 5 is an isometric view of a barrel guide and stop member in combination with a slide stop-open latch
  • FIG. 6 is an enlarged schematic view of a firing mechanism of this invention at the instant of hammer release.
  • FIG. 7 is an enlarged section view taken generally along line 77 of FIG. 1.
  • an automatic pistol 10 embodying this invention is shown generally comprising a frame or receiver 12, barrel l4 and operating slide 16 suitably supported for reciprocable sliding movement on the receiver 12.
  • the slide 16 moves rearwardly to an extent limited by an abutment wall 18 on the receiver 12.
  • a shoulder '20 inside the slide 16 engages an enlarged rear barrel portion 22 to drive the barrel l4 rearwardly with the slide 16 from its forward position shown in FIG. 1.
  • the barrel 14 disengages from .the slide 16 during its rearward movement and is arrested at an intermediate point in the travel of the slide 16 to provide for cartridge extraction and ejection and to strip a live round from a magazine (not shown) to be chambered within the barrel 14 upon the return forward movement of the slide 16 under the force of its action spring 24.
  • a firing mechanism hammer 26 is cocked by the slide 16 during its rearward movement.
  • the pistol l0 utilizes a well known firing operation wherein pivoting its trigger 28 rearwardly about a pivot pin 30 moves a trigger bar 32 forwardly for actuating the hammer26.
  • Both single and double action firing mechanism movements are provided for in the pistol 10 of this invention.
  • the hammer 26 In a single action movement the hammer 26 is manually cocked by its thumbpiece 34 and then released from cocked position by a trigger squeeze.
  • a double action movement the hammer 26 is both cocked and fired by a single trigger squeeze.
  • the trigger bar 32 has an inwardly directed rear finger 36 suitably stepped and configured to form a double action shoulder 38 and a sear engaging face 40 (FIG. 6).
  • the double action shoulder 38 engages a double action hammer sear 42 to pivot hammer 26 from its at rest position (FIG. 1) into a fully cocked position, such that upon further trigger pull, a tail of the finger 36 contacts the hammer 26 inside its double action notch 44 to disengage the trigger bar 32 to drop the hammer 26.
  • the sear engaging face 40 of the trigger bar 32 engages a single action sear 46, pivoting it clockwise out of the path of movement of the hammer 26 to avoid unintended engagement with its full cock and half cock notches 48, 50.
  • the hammer 26 falls freely into fired position, pivoting about its fixed pin 52 under the force of its main spring 54 and strikes the firing pin 56 to fire a cartridge.
  • a projecting disconnector hammer surface 58 engages the trigger bar 32 to drive it downwardly to automatically disengage the bar 32 from the single action sear 46.
  • the single action sear 46 is automatically returned to engage the hammer 26 under the biasing force of its torsion spring 60, and the trigger 28 and its bar 32 are returned to their illustrated at rest positions (FIG. 1) under the bias of a common torsion return spring 62 which continuously urges the trigger 28 forwardly and the trigger bar 32 upwardly into contact with the hammer 26.
  • the hammer 26 also may be manually cocked to engage the single action sear 46 in the full cock hammer notch 48. (As previously noted, the hammer 26 is also placed in this condition by recoil operation of the slide 16 upon firing.)
  • the trigger bar 32 then moves forwardly responsive to trigger actuation to engage the single action sear 46.
  • trigger pull the bar 32 moves in a path generally parallel to the hammer surface in its double action notch 44 to drive the single action sear 46 out of engagement with the hammer 26.
  • hammer 26 Upon release, hammer 26 drops responsive to a positive force applied along the length of its strut 64 under the bias of the compressed main spring 54 shown coiled about a plunger 66 having a recessed head 68 forming a seat for the hammer strut 64.
  • Various firing mechanism components mentioned above have been incorporated in a unitary fire control group 70 of an en bloc type particularly suited to be quickly and easily assembled and removed for facile field maintenance as a single-piece unit relative to the receiver 12.
  • en bloc fire control groups of the known prior art are either too tightly wedged or too loosely seated in the receiver. If the en bloc fire control group is too tightly fitted, anticipated advantages desired in quick and easy disassembly and reassembly are replaced by frustration. in the absence of a construction permitting a relatively loose fit, close manufacturing tolerances must be adhered to or hand fitting must be employed, approaches which are neither practical or desirable in a mass production operation and which have a tendency to become loosened and unstable.
  • Loosely fitted en bloc fire control groups exhibit a characteristic rocking action in directions of hammer pivoting, and it may be necessary to resort to an undesired double military pull to take up slop and play in the firing mechanism through a substantial portion of the trigger squeeze before a crisp trigger pull is reached just before firing.
  • attempts to precisely locate en bloc fire control groups by the use, e.g., of cross pin connections extending laterally of the receiver have resulted in undesirably increasing the size of the firing mechanism components to an un manageably large extent, particularly when the versatility of both single and double action movements of the above-described firing mechanism is desired.
  • the en bloc fire control group 70 of this invention is particularly suited to be positively located in the receiver 12 with a relatively loose fit while stabilizing the fire control group 70 a sufficient distance from its hammer pivot axis X-X to minimize or eliminate any tendency toward unintended movement of the fire control group 70.
  • the latter is provided a housing 72 having pins 52, 74 and 76 fixed therein for supporting the hammer 26, single action sear 46 and its spring 60 for pivotal movement, and additionally supporting the hammer strut 64, main spring 54 and its associated plunger 66 in a compact unitary assembly for quick and easy insertion and removal relative to the receiver 12 of the pistol 10.
  • an elongated downwardly projecting housing extension including a plug 80 and a tubular portion 82 within which the main spring 54 is received with one end seated against a bottom shoulder of the head 68 of the plunger 66. An opposite end of the main spring 54 seats against the housing extension plug 80.
  • the main spring 54 is preloaded and exerts a continuous force on the plug 80 to maintain its radial pin 84 against unintended movement relative to an L shaped slot 86 formed in the end of the tubular housing portion 82.
  • the free rear finger 36 of the trigger bar 32 need only be positioned within a window (not shown) in the housing 72, and the fire control housing 72 is then simply inserted into its pocket 90 within the receiver 12.
  • a rear wall 92 of the housing 72 and a front face 94 of a side projection 96 on the housing 72 are provided bearing support by surfaces 98, 100, respectively, within the pocket 90 of the receiver 12, and the plug projecting downwardly beyond the end of the tubular portion 82 is fitted within a bottom opening 102 in the hand grip 88.
  • the plug 80 not only serves as a pilot to precisely locate the fire control group 70 within the receiver 12, but also serves to restrain the fire control group 70 against unintended fore and aft oscillatory movement within the receiver 12. Upward movement of the fire control group 70 is restrained by the slide 16.
  • any tendency of the fire control group 70 to rock during hammer cocking e.g., thus will be effectively restrained by the engagement of the housing extension plug 80 and the receiver 12 to minimize any free trigger travel.
  • the effective lever arm to the hammer pivot axis X-X is of maximum length and only a minimal amount of force is transmitted between the housing extension plug 80 and the receiver 12 which additionally minimizes any parts wear and limits any angular motion of the housing 72 in directions of hammer pivoting to an absolute minimum for a given tolerance.
  • the described en bloc fire control group 70 is of exceptionally compact construction permitting use of a minimum number of working parts and a large capacity magazine of, say, fifteen rounds to be loaded in the magazine well 104 of the hand grip 88.
  • the pistol 10 can be provided an all steel frame in a large caliber such as a 9 mm or a 0.45 caliber and yet be of relatively light weight, in the order of 35 ounces or less. Due to the provision of the en bloc fire control group 70 of this invention, no need exists for a separate wall defining the magazine well 104 within the hand grip 88.
  • the en bloc fire control group 70 additionally locks grip panels 108, 108 in place on the hand grip 88 without any need whatsoever for screws or similar conventional fasteners.
  • Dovetailed channels are formed on opposed edges of the hand grip 88, such as at 110, 112, and along opposed lower hand grip edges as shown at 1 14 for positioning the grip panels 108, 108 which then can be simply slid into the dovetailed channels which maintain the grip panels against forward and downward movement.
  • the grip panels 108, 108 are removably locked in position and limited against rearward movement by outwardly projecting ribs 116, 1 16 on opposed sides of the tubular portion 82 of the housing extension, simply upon positioning the fire control group 70 within the receiver 12.
  • a positive barrel guide and stop mechanism 120 is provided of a significantly improved construction particularly suited for quick and easy mass production and free of manufacturing difficulties even though extremely close tolerance requirements are established for precision barrel movement between limit positions.
  • a barrel lug 122 projects downwardly from the enlarged rear barrel portion 22 in a vertical plane, extending through the longitudinal center line of the barrel 14, for limited captured movement between a pair of camming pins 124, 126 operatively fixed to extend laterally in longitudinally spaced relation across the receiver 12.
  • the barrel lug 122 has front and rear abutments 128, 130 of arcuate shape conforming to confronting peripheral surfaces of the front and rear camming pins 124, 126 which are of circular cross section.
  • the rear camming pin 126 is fixed rearwardly of the lug 122 and offset slightly downwardly of the conforming rear lug abutment 130 in its forward barrel position, shown in FIG. 1, in interfering relation to its path of rearward movement.
  • the forward camming pin 124 Upon movement of the slide 16 retracting the barrel [4, the forward camming pin 124 supports a flat contact face 134 on the barrel lug 122 extending between its front abutment 128 and a forwardly and upwardly extending inclined shoulder 136 on the leading face of the barrel lug 122. After the contact face 134 clears the forward pin 124, the rear abutment 130 engages a lower portion of the rear pin 126 which cams the barrel l4 downwardly to an extent limited by full contact engagement between the confronting surfaces of the lug abutment 130 and rear camming pin 126, thereby establishing a lowered rear limit position (FIG.
  • the rear camming pin 126 not only serves to guide the barrel 14 downwardly to disengage the slide 16, but also assists receiver rails 138 in stopping rearward barrel movement.
  • the forward camming pin 124 is fixed forwardly of and below the rear pin 126 to provide a relatively large area of intersurface contact with the barrel lug 122 to positively guide and stop the barrel 14 in a raised forward limit position, shown in FIG. 1, in locked engagement with the slide 16.
  • the forward pin 124 guides the barrel 14 upwardly into reengagement with the slide 16 upon its return forward movement.
  • the forward pin 124 which is in interfering relation to the path of forward travel of the barrel lug shoulder 136, cams the barrel 14 upwardly in timed relation to the forward movement of the slide 16 to position the enlarged rear barrel portion 22 between slide shoulders 20, 140.
  • the forward camming pin 124 not only guides forward barrel movement by its engagement with the shoulder 136 and the contact face 134, but also effectively stops forward movement of both the barrel l4 and slide 16 in operative position with the pistol 10 conditioned for the firing of the next live round.
  • the circular cross-sectional construction of the camming pins 124, 126 enhances their being very accurately and easily positioned in place during a simplified mass production operation virtually free of any manufacturing difficulties while yet meeting critical tolerance requirements.
  • Two precisely located holes are simply drilled in the receiver 12 for placement of the pins, an operation which can be repeatedly performed rapidly and accurately.
  • the camming pin 124 may provide additional-functions, e.g., as a pivot axis for a slide stop-open latch 142.
  • the forward pin 124 is shown detented in the receiver 12 against undesired lateral and pivotal movement by a spring-biased plunger 144 projecting rearwardly from the hollow guide rod 146 to engage a recessed seat 148 in the pin 124 to continuously bias a rearwardly extending arm 150 of the slide stop-open latch 142 counterclockwise, urging the latch 142 into a lowered position against a bottom surface 152 of a window 154 in the receiver 12.
  • the latch 142 is conventionally actuated by a magazine follower 156 to move the latch 142 upwardly to engage a notched surface 158 in the slide 16 to prevent its return forward movement under empty magazine conditions.
  • the forward pin 124 additionally may be used to serve as a takedown pin to permit quick and easy disassembly and reassembly of the barrel 14 from the slide 16.
  • An intermediate portion of the pin 124 is shown partially cut away to form a recessed shoulder 160 of about the width of the barrel lug 122.
  • the shoulder 160 would normally face forwardly in operative position.
  • the described structure is particularly suited to provide a dependable, high performance, quality pistol 10 which is quickly and easily assembled and manufactured at significant savings of cost and time.
  • Excellent fitting and stabilization of the en bloc fire control group 70 is achieved without close tolerance requirements, while precision placement of the barrel camming pins 124, 126 is readily provided for, free of manufacturing difficulties even in a mass production operation.
