A rounds counter is located in the stock and comprises a control lever projecting from the upper side of the stock and located in the path of the breech mechanism of the pistol recoiling at the time of firing and a part controlled by the control lever, which returns the control member to the individual firing position on reaching an end position and due to this interrupts the firing sequence. The trigger mechanism of the pistol is provided with a member engaging in the stock. which member, so long as the trigger of the pistol is pulled keeps in an operative position a control member which, in its inoperative postion, releases the controlled part for return to its initial position.

8 Claims, 6 Drawing Figures PATENTED JANZ 1 I975 SHEET 2 OF 2 6 3 44 fig 592 705 57 SELF-LOADING PISTOL WITH A STOCK The invention relates to a self-loading pistol with a trigger mechanism which may be changed over to continuous fire and with a stock to which the pistol is detachably connected by the rear side of the grip and in which a control member is provided serving for changing over the trigger mechanism to continuous fire and actuated by means of a change-over switch.

A self-loading pistol of this type is shown in German Utility Model (Gebrauchmuster) No. 6,752,884. This known self-loading pistol permits continuous firing when it is attached to the stock and thus has a very high firing power. At the same time it is ensured that when the pistol is detached from the stock, only individual shots may be fired, because a pistol set to continuous fire, without the support of a stock, cannot be kept on target. However, it is also difficult to fire continuously with the self-loading pistol attached to the stick, because these pistols have an extremely high firing speed, which may amount to 2,000 and more shots per minute and the magazines of pistols have a limited capacity so that the person using the gun is generally only in a position to give a single burst of fire, because with the specified high firing speeds, the magazine of a pistol of this type is empty in fractions of a second. Undoubtedly, the high firing power of a self-loading pistol of this type could be better utilised, if it were possible to give several controlled bursts of fire despite the high firing speed.

Accordingly, it is an object of the invention to improve the self-loading pistol of the afore-described type so that it is possible to discharge several controlled bursts of fire from a single magazine.

This object is achieved according to the invention in that in the stock to which the self-loading pistol is attached, a rounds counter is provided which comprises a control lever projecting from the upper side of the stock and located in the path of the breech mechanism of the pistol recoiling at the time of tiring and a toothed part controlled by the control lever, which part is held in its respective position by a spring-loaded lock pawl and when it reaches an end position, the toothed part restores the control member to the single-shot position so that the firing sequence is interrupted and that the trigger mechanism of the pistol is provided with a member engaging in the stock which, so long as the trigger of the pistol is pulled, keeps a control member, which in its inoperative position keeps the lock pawl out of engagement with the toothed part, in an operative position in which the lock pawl is free to engage the toothed part.

Thus, in order to limit the bursts of fire to a predetermined number of shots, the self-loading pistol according to the inventiom uses a rounds counter, as is known in a similar manner from rifles. Thus, a rounds counter is known, for example from German Pat. No. 1,121,981, which is intended for a rifle with percussion priming by means of a hammer and in which, substantially below the hammer, a control lever is provided with an arm extending into the path of the hammer, on which arm a pawl is pivoted serving for actuating a ratchet wheel. Provided on the ratchet wheel is a control path constructed in the manner of a cam, which after a certain number of shots tilts the trigger of the rifle against the trigger movement to interrupt the se quence of shots so that it releases a pawl serving for catching the hammer. However, a rounds counter of this type cannot be used for pistols because there is no possibility of locating a control lever projecting into the path of the hammer, below the hammer of a pistol and furthermore, considerable difficulties exist in accommodating a trigger mechanism in the grip of a pistol, which mechanism may be changed over to continuous fire, so that there is not space available in a pistol for a rounds counter of conventional construction. These difficulties are overcome by the invention in that it accommodates the rounds counter in the stock and makes the connections to the pistol necessary for the operation of the rounds counter in a manner such that a trouble free operation of the rounds counter as well as the pistol is ensured and in particular there is still no possibility of discharging continuous fire or even only controlled bursts of fire with the pistol when the pistol is separated from the stock.

In a preferred embodiment of the invention, in which the control member is formed in known manner by a control pin displaceable in its longitudinal direction, which is loaded by a spring in the direction of the continuous firing position and may be brought into the single-shot position by means of the change-over switch against the force of this spring, the toothed part is formed by a ratchet wheel which in its end position engages by a protrusion behind a shoulder on the control pin and thus keeps the control pin in the single-shot position independently of the position of the change-over switch. The protrusion on the ratchet wheel may simply be formed by a pin inserted in the ratchet wheel and projecting laterally therefrom.

If the trigger mechanism of the piston comprises in known manner a trigger arm which is displaceable in its longitudinal direction, then in a further development of the invention, this trigger arm may have a projection engaging in the front end of the stock when the trigger is actuated and in the stock, as an extension of this projection, a control rod may be mounted to displace in its longitudinal direction as the control member, which rod is held by a spring in its inoperative position in which it engages by a lateral projection behind an arm located on the lock pawl and which may be deflected from this inoperative position in order to release the lock pawl by withdrawing the trigger from the extension of the trigger arm. Thus, in this embodiment of the invention, no complicated gears are used to restore the rounds counter to its initial position when the trigger is released and to make it ready for operation when the trigger is actuated, but solely a control rod is displaced by means of the trigger arm, i.e., the rectilinear movement of the trigger is transmitted directly to the lock pawl so that an extremely simple and at the same time utterly reliable arrangement results. Furthermore, the members which are displaceable in their longitudinal direction, such as the control pin and control rod, do not require much space, so that the mechanism according to the invention may be easily accommodated in a narrow space. Finally, with this type of transmission of force, no great stresses occur on the individual components, which likewise has a favourable effect on the durability of the arrangement.

In a further development of the invention, the control lever may comprise an arm located in the effective range of the change-over switch, with which arm the change-over switch engages in the single-shot position and which it keeps in a position in which the control lever is located entirely inside the stock. In this case, a person using the gun will immediately perceive from the position of the control lever, whether his weapon is set to individual fire or continuous fire. Moreover, since in the above-mentioned known self-loading pistol, care is taken that the pistol may only be separated from the stock when the change-over switch has previously been set to individual fire, the control lever is thus always in a protected position inside the stock when the stock is used independently of the pistol or as a pistol-case.

A particularly simple arrangement results if the change-over'switch comprises a drum switch with a switching blade and the drum switch has a notch for the arm of the control lever, in which this arm engages in the continuous firing position, whereas in the singleshot position, it lies against the periphery of the drum switch. If a displaceable control pin is mounted in the stock as a control member, it is sufficient, if the drum switch has a pin engaging in a recess of the control pin, to undertake the change from individual fire to continuous fire and vice versa by rotating the drum switch.

The rounds counter and control member are appropriately located in a separate housing inserted in the stock, which housing is preferably held in the stock by the pinning action of the drum switch.

Further details and refinements of the invention will become apparent from the following description of the embodiment illustrated in the drawing. The features contained in the description and drawing may be used in other embodiments of the invention, individually or together in any combination.

FIG. 1 is a side view of a pistol with a stock according to the invention,

FIG. 2 is a section on line IIII through the adjacent sections of pistol and stock of the arrangement according to FIG. 1,

FIG. 3 is a section on line III-III through the arrangement according to FIG. 2,

FIG. 4 is a plan view of the mechanism comprising control members and a routine counter inserted in the stock according to FIG. 1,

FIG. 5 is a section on line V-V and FIG. 6 is a section on line VIVI through the apparatus according to FIG. 4.

As may be seen from FIG. 1, the pistol l illustrated as an embodiment, which consists essentially in known manner of a grip 2 and a breech mechanism 3 mounted for longitudinal displacement in a direction opposite the grip, is attached to the front end of a stock 4 by the rear side of the grip 2. The stock 4 consists of a hollow body made from synthetic material which is simultaneously constructed as a pistol-case and at its rear end has a cover 5 which forms the support surface 6 to be placed against the shoulder. As is shown in dot-dash line in FIG. 1, a pistol inserted in the stock 4 protrudes by its grip 7 from a lateral opening in the stock 4 constructed as a case so that the pistol may be easily gripped. For connecting the stock to the pistol, four T- shaped sliding members 8 are located on the front end face of the stock 4, which members may be inserted into corresponding undercut recesses 9 on the rear side of the grip 2 of the pistol l.

The trigger mechanism 11 located in the grip 2 of the pistol has two longitudinally displaceable trigger arms connected to the trigger 12 in a manner which is not shown in detail and each guided on a pin 14 by means of a longitudinal slot 13. Mounted between the trigger arms 15 is an entrainment means 16 displaceable at right-angles to the trigger arms, which entrainment means has an inclined face 17 projecting into the region of the slots 13. A spring 18 which is supported on a lug 19 bent out of the plane of one of the trigger arms 15, is biased to keep the entrainment means 16 in its uppermost position in which a shoulder 20 thereof is disposed in front of a projection 21 of the firing pin 22. When the trigger 12 is pulled, the trigger arms 15 are moved rearwards with the entrainment means 16. Thus, the entrainment means 16 entrains the firing pin 22-by the'projection 21' until the inclined face 17 of the V entrainment means 16 comes to bear against the pin 14, whereupon the entrainment means 16 is moved downwards and releases the firing pin 22. The firing pin spring 23 then drives the firing pin dorwards to detonate a cartridge.

The trigger mechanism 11 also has a catch pawl 24 which is pivoted on a pin 25 outside the space between the trigger arms 15 and permit continuous firing. As long as the pistol is set to individual fire, this catch pawl is held by an actuating rod 26 in an inoperative position. The actuating rod 26 is mounted for displacement in the longitudinal direction of the pistol in the rear part of the grip 2 and is loaded by a compression spring 27 which is urged to push the actuating rod rearwards, i.e., outwards. At its front end projecting into the grip 2, the actuating rod 26 is provided with a collar 28 which is located behind a lug 29 projecting from the catch pawl 24 such that the catch pawl 24 is prevented from rotating in clockwise direction, as illustrated in FIG. 3. In this position, a projection 30 provided at the upper end of the catch pawl is located outside the path of the projection 21 provided on the firing pin 22. In addition, a further projection 31 engages below an elbow 32 provided on the adjacent trigger arm 15, when the trigger arm is located in its inoperative position, i.e., the trigger is not actuated. Therefore, the catch pawl 24 may only come into engagement with the firing pin when the trigger is actuated, so that it is avoided, for example, that a shot may be discharged when loading the weapon.

On the other hand, if the actuating rod 26 is moved inwards and the trigger is simultaneously actuated so that the trigger arm 15 is located in its extreme rear position and the entrainment means 16 is moved out of the region of the projection 21 on the firing pin 22 and the elbow 32 is moved out over the projection 31 on the arm of the catch pawl 24, the catch pawl 24 may be swung by a leg spring 33 loading it, so far in the clockwise direction that its upper projection 30 comes into the region of the projection 21 on the firing pin 22. The projection 30 on the catch pawl 24 holds the firing pin 22 stationary by the projection 21 if the breech mechanism 3 has moved into its extreme rear position with the firing pin 22. When the breech mechanism is once more brough forwards in known manner by the breech closing spring, a cam path located on the breech mechanism and not shown in detail moves the catch pawl 24 downwards so that the firing pin 22 is released for discharging a further shot, when the breech mechanism comes into its forwards position. This working cycle is repeated until either by releasing the trigger, the projection 31 on the arm of the catch pawl 24 is located behind the elbow 32 on the trigger arm 15, so that the catch pawl 24 is once more returned to its inoperative position in which it is inactive or the catch pawl 24 is restored to its inoperative position by the collar 28 on the actuating rod 26 returning to its inoperative position.

The preceding details make it clear that the change over of the exemplary pistol from individual fire to continuous fire may be achieved in that the actuating rod 26 is pushed out of its inoperative position which it assumes under the force of the spring 27 and which is illustrated in FIG. 3, against the force of this spring into an operative position in which the projection 30 of the pawl 24 co-operates with the projection 21 on the firing pin 22. The members which facilitate an adjustment of this type of the actuating rod 26 are located in the stock 4. These members comprise a control pin 34 which is mounted for longitudinal displacement in the extension of the actuating rod 26 of the attached pistol 1 in a housing 35 inserted in the stock 4. This control pin 34 engages with its front end projecting from the front of the stock 4 in the bore in which the actuating rod 26 is mounted in the grip 2 of the piston 1. Located at the rear end of the control pin 34 is a compression spring 36 which is urged to push the control pin 34 out of the stock and into the bore provided on the rear side of the grip for the actuating rod 26.

A change-over switch serves for regulating the type of fire and comprises a drum switch 37 penetrating the housing 33 transversely and a switching blade 38 located on the end of the drum switch. As shown in FIG. 1, the switching blade 38 is located on the outer side of the stock 4 and may be tilted in order to rotate the drum switch 37. In the position illustrated in the drawing, the pistol is set for continuous fire. Thus, a pin 39 inserted radially in the drum switch 37, which pin engages at its free end in a recess 40 of the control pin 34, releases the control pin so that it may be pushed by the compression spring loading it into the bore provided on the rear side of the grip for the actuating rod 26 and the actuating rod releases the pawl 24 in the abovedescribed manner in order that it may co-operate with its upper projection 30 with the projection 21 of the firing pin 22. On the other hand, if the switching blade 38 in FIG. 1 is swung downwards in clockwise direction by about 30 so that it covers the notch 41, then the control pin 34 is moved rearwards by the pin 39 inserted in the drum switch 37 against the force of the compression spring 36 so far that it releases the actuating rod 26 in the pistol, the actuating rod is brought into the inoperative position by the spring 27 loading it and thus brings the catch pawl 24 into its inoperative position in which this catch pawl is inactive.

Even when the gun is set to continuous fire, in order that only a limited number of shots may be discharged and that the entire magazine of the pistol is not emptied with a single burst of fire, which is practically unavoidable with the high firing speed of pistols of this type, the pistol according to the invention is provided with a rounds counter. This rounds counter comprises a ratchet wheel 42 mounted to rotate in the housing 35 and loaded by a leg spring 43 (illustrated in FIG. 6) arranged to keep the ratchet wheel 42 in an inoperative position in which it bears with a projection 44 against a protrusion 45 of the housing 35. A control lever 46 likewise pivoted in the housing 35 serves for the forwards movement of the ratchet wheel 42, which con trol lever extends in a direction substantially opposed to the firing direction and when the gun is set to continuous fire projects from the upper side of the stock 4, as shown in FIG. 1. The control lever 46 is therefore located in the path of the rear end plate 47 of the breech mechanism 3, which passes with its lower edge 48 along the upper edge 49 of the control lever 46 when the breech mechanism is recoiling and due to this pushes the control lever into the stock 4 so that it carries out a swinging movement in clockwise direction about its shaft 50. At its free end, the control lever 46 has a U- shaped flange 51 which is bent back, which is located opposite to and spaced from a section of the control lever 46 at a distance and together with this section forms a fork in which a pawl 53 is pivoted on a pin 52. The pawl is loaded by a compression spring 54 which is supported on the one hand against the back of the pawl and on the other hand on the bar 55 connecting the flange 51 to the control lever 46. In its inoperative position, the pawl 43 is kept in abutment with a projection 56 on a pin 57 inserted in the control lever 46, which pin 57 simultaneously serves as an abutment for a leg spring 58 which is located on the same pin 59 on which the ratchet wheel 42 is also mounted and is sup ported at its other side on the underneath of the protrusion 45 of the housing 35. This leg spring 58 is urged to swing the control lever 46 in anti-clockwise direction and thus to press it out of the upper side of the stock. A lock pawl 61 is also pivoted in the housing 35 on a pin 60, which lock pawl is loaded by a leg spring 62. This leg spring is located on a pin 63 inserted in the control lever 46 and is supported on the one hand, on the edge of the pawl 53 and on the other hand, on the edge of the lock pawl 61. The leg spring 62 is urged to bring the lock pawl 61 into engagement with the ratchet wheel 42. Finally, a control rod 64 is mounted to displace in its longitudinal direction in the housing 35, which control rod is loaded by a compression spring 66 located on a guide pin 65. The compression spring is urged to push the control rod 64 towards the front end of the stock 4 and thus to keep it in an inoperative position in which it engages by a lateral projection 67 behind an arm 68 on the lock pawl 61 and due to this keeps the lock pawl 61 out of engagement with the ratchet wheel 42 against the force of the leg spring 62 loading the lock pawl. As may be seen from FIGS. 2 and 3, the front end of the control rod 64 is opposite a projection 69 of one of the two trigger arms 15 of the trigger mechanism located inside the pistol. If, on firing the pistol, the trigger arms are displaced rearwards, then the extension 69 of one trigger arm 15 leaves the grip 2 of the pistol rearwards, strikes against the control rod 64 and pushes this control rod against the force of a compression spring 66 so far in a rearwards direction that the arm 68 of the lock pawl 61 is released by the lateral projection 67 of the control rod 64 and the lock pawl 61 may drop into the ratchet wheel 42.

If the switching blade 38 is set to continuous tire and consequently the control pin 34 assumes its forwards position, as illustrated in FIGS. 4 and 5, the first shot is released on actuating the trigger of the pistols. The recoiling breech mechanism 3 then pushes the control lever 46 projecting from the upper side of the stock 4 downwards so that the pawl 43 encounters the tooth 70 of the ratche wheel 42 which is the most remote in clockwise direction and rotates the ratched wheel in clockwise direction. The ratchet wheel then assumes the position illustrated in FIG. 5, in which it is retained by the lock pawl 61 released when the trigger is actuated. At the time of the second shot, the pawl 53 descending together with the control lever 46 encounters the next tooth 71 of the ratchet wheel 42 and moves the ratchet wheel on further. In this new position also, the ratchet wheel is once more held by the lock pawl 61 which now engages behind the tooth 72 adjacent the projection 44. The ratchet wheel 42 now assumes a position in which a pin 73 inserted in the ratchet wheel and projecting laterally therefrom engages behind the shoulder 74 on the control pin 34 and due to this pushes the control pin 34 so far backwards that it releases the actuating rod 26 in the pistol l for returning to its inoperative position. Consequently, the catch pawl 24 in the pistol is swung into the inoperative position so that, after the breech mechanism of the pistol has moved forwards and the third shot has been discharged, during the recoil of the breech mechanism after the third shot, the firing pin is no longer caught by the catch pawl 24, but the firing sequence is interrupted. If the trigger is then released, simultaneously the control rod 64 of the rounds counter is released, which lifts the lock pawl 61 from the ratchet wheel 42 so that the ratchet wheel may return to its inoperative position. Due to this, the control pin 34 is also released in order to return to its initial position, which now changes over the trigger mechanism in the pistol to continuous fire so that when the trigger is once more actuated a firing sequence of three shots is discharged, which is indicated by the number 3 adjacent the continuous firing position of the switching blade 38 in FIG. 1. The FIG. 1 adjacent the notch 41 for the single-shot position of the switching blade 38 is intended to indicate that in this position of the switching blade only one shot is discharged when actuating the trigger 12.

The housing 35 with the rounds counter is inserted into the stock from the front together with a cover 75 and is solely held by the pinning action of the drum switch 37. The cover 75 has only one slot for the passage of the control lever 46. Furthermore, at its rear end, the control lever 46 is provided with an arm 76 projecting approximately at right-angles and indicated in broken line in FIG. 5, which arm engages in a recess in the drum switch 37 when the latter is set to continuous fire, whereas in the individual firing position of the drum switch 37, the arm 76 of the control lever 46 bears against the periphery of the drum 37, due to which the control lever 46 is tilted so far that it no longer protrudes beyond the outer side of the stock 4.

It is clear that owing to the invention a self-loading pistol with a trigger mechanism which may be changed over to continuous fire, which may be attached at the rear side of its grip to a stock in which the mechanism for changing the trigger device of the pistol over to continuous fire are located, is provided with a rounds counter which does not form a part of the trigger mechanism in the conventional manner, but which is accommodated in the stock and acts on the change over members located in the stock and returns these change over members from the continuous firing position to the individual firing position in order to interrupt a firing sequence. This return movement to the individual firing position nevertheless takes place such that the chosen continuous firing position is restored when the trigger of the pistol is once more released after the completion of a firing sequence.
