1 Claim, 10 Drawing Figures 0-D 5 30 30\ 3 34 30 I o N: 1 11 o, O O O O 0 Q 5 REPEATING PISTOL This is a divisional of applicants earlier application, Ser. No. 56,914 of July 21. 1970, on a Repeating Pistol, issued on Sept. ll, 1973 as US. Pat. No. 3,757,634.
Our invention has for its object a repeating pistol provided with a charger and intended for severely controlled contest firing.
In all known pistols of this type, the pull off and striking mechanisms do not ensure a sufficient range of adjustments as may be required by the marksman just before firing. Furthermore, such mechanisms were hitherto intricate and delicate.
The repeating pistol according to our invention removes such drawbacks in a manner such that the adjustments performed prior to firing allow in succession a modification in the pressure exerted on the trigger in accordance with the load applied, an adjustment of the stroke of said trigger independently of said pressure, an adjustment of the stop provided to the front of the trigger so as to define its idle stroke before it drives the sear through the agency of the intermediate connecting link and finally the adjustment of the pressure exerted by the blade spring against the sear.
According to a further feature of our invention, the micrometric back sight is secured directly to a structure rigid with the pistol body.
According to a still further feature of our invention, the movable bolt or breech block adapted to slide longitudinally with reference to the pivotal body cooperates at its front end with a collapsible bolt acting as a stop so as to allow or prevent its dismantling as required.
The setting of the pistol may be obtained by means of the intermediate sliding connecting link inserted between the sear and the trigger, said connecting link showing adjacent the rear of the pistol a setting notch cooperating with a projection on the sear so as to drive the latter, while a safety lever pivotally secured to the pistol body is adapted to release the intermediate connecting link.
According to a further feature, the stroke of the striker slidingly carried at the rear of the movable breech block may be accurately defined so that the striker may engage a collapsible stop fitted vertically inside said breech and may lock the stop against movement.
The tang or shoulder engaging the palm of the markmans hand and which is carried by the grip of the pistol may be advantageously adjusted as to position over a large range through the agency of an invertible supporting plate.
These features will appear with others in the reading of the following description of an embodiment of our invention to be disclosed hereinafter, referencebeing made to the accompanying drawings, wherein:
FIG. 1 is a side view of the pistol, partly sectional, the movable breech block being shown in an operative position before firing, the grip not being illustrated.
FIG. 2 illustrates on a smaller scale and in perspective view a section of the grip with the palm-engaging tang thereon.
FIG. 3 is on a larger scale a cross-section through line III-III of FIG. 2, the tang being in its lowermost position.
FIG. 4 is a view similar to FIG. 3, the tang occupying however a higher position following a rotary motion of its supporting plate. FIG. 5 is a longitudinal sectional view of the pistol, the movable breech occupying its rearmost retracted position prior to its dismantling as shown in interrupted lines.
FIG. 6 is a view from above. partly sectional through line VI-VI of FIG. 5.
FIG. 7 is an end view, partly sectional through line VIIVII of FIG. 5.
FIG. 8 is a transverse cross-section through line VIII- VIII of FIG. 5.
FIG. 9 is a perspective view of the collapsible bolt latch.
FIG. 10 is a perspective exploded view of the striker in alignment with its collapsible stop.
As illustrated, the repeating pistol includesa unitary body 1 in the front end of which may be securely fitted pistol barrel 2 while its rear end forms a large-sized structure 1 to the upper surface of which is secured a conventional micrometric sight carried directly by the structure 1.
The body 1 is provided laterally with longitudinal grooves 1 along which a movable breech block or bolt 3 is adapted to slide freely. Said breech block bears against the rear end of the barrel and includes at its front end a depending rounded tongue 3 slidingly engaging the longitudinal U-shaped opening formed in the front end of the body 1. A guiding rod 4 fitted inside an axial blind bore formed in the body 1 is surrounded by a coil spring 5 which normally urges the breech block 3 back into its operative-position.
In its rearmost retracted position, the movable breech block 3 has its guiding means 3 disengaged with reference to the above-mentioned groove 1 in the body 1 whereby the successive dismantling operations may be executed by means of vertical releasing movements as illustrated in interrupted lines in FIG. 5 and of a handcontrolled progression so as to release the tongue 3 with reference to the cooperating opening in the body 1.
Said dismantling is allowed by a collapsible latch 6 adapted to slide vertically along one of the lateral surfaces of the body I while its front surface 6 is that which allows the extreme receding motion of the breech block 3 (FIG. 9).
When the latch is in its lowermost position (FIG. 1'), its upper part forms a projecting tail piece 6 defining the end of the stroke of the tongue 3 for which itforms a stop whereby the disengagement of the guidingmeans 3 on the movable breech with reference to the body is prevented and consequently the dismantling becomes impossible.
The latch 6 is held fast in each of its extreme positions by a ball 7 subjected to the action of a spring housed within a hole formed in the body 1.
In the movable breech 3, a striker 8 may slide axially, the rear end of said striker forming a cylindrical head 8 the side of which is cut so as to form a flat-bottomed transverse groove 8 the length of which longitudinally of the striker is designated by X. Said flat-bottomed groove may be shifted between the projecting edges of a corresponding U-shaped opening 9 formed in a detachable stop or plate 9 fitted vertically in a corresponding recess in the movable breech block 3 (FIG. 10). It should be remarked that the length of the edges of said opening 9 is equal to a value Y which is smaller than the length X of the groove 8 so as to accurately define the longitudinal stroke of the striker 8, the transverse edges of the groove 8 located inside the opening 9 abutting against the transverse ends of said projecting edges of the latter. The length of such a stroke is thus equal to X-Y as illustrated in FIG. 5.
The front section of the striker 8 carries a coil spring 10 normally urging the striker rearwardly. Said spring housed within a shouldered chamber formed in the movable breech block 3 urges permanently a cylindrical section 8 of the striker head lying to the front of the groove 8 rearwardly into a chamber of a corresponding diameter 9 to the front of the opening 9 so as to provide a longitudinal fitting which prevents when the striker has been retracted, an undesired release of the stop 9 inside the movable breech 3.
The release of the stop 9 is obtained by pushing the striker so as to make its front section 8 move out of the chamber 9 The body 1 is recessed in its upper rear part in order to form a housing for a rocking hammer l1 pivotally secured to a spindle 12. The lower end of this hammer is coupled through a pivot 13 with the end of a pusher lever 14 round the outer end of which a coil spring 15 is wound, said spring axially engaging a cleat l6 fitted inside a transverse recess of the body 1 by means of a pin 17.
Along its lower rounded edge, the hammer 11 includes a notch 11 adapted to engage when the pistol is being set, the projecting nose on a sear 18 being pivotally secured to a rod 19 rigid with the a safety lever 19 (FIG. 1).
A blade spring 20 inserted vertically in a recess formed in the body 1 forms substantially at mid-length a loop bearing on a transverse pin 21. The upper shaped section of the spring 20 engages the upper front surface of the sear 18 while the opposite end of the spring is urged into abutment with the body by the tip of a screw 22 housed inside a transverse dove-tailed cleat 23 fitted inside the body 1.
Through this arrangement it is apparent that the screwing of the screw 22 by the desired amount produces a suitable tensioning of the lower end of the spring 20 and consequently an adjustable stress may be exected in the opposite direction on the sear 18 which is thus thrust forwardly to ensure a hooking engagement by the desired amount with the hammer 11.
It should be remarked that the screw 22 is provided outwardly with longitudinal grooves cooperating with spring-urged positioning balls housed within holes provided in the cleat 23.
It should also be remarked that the sear 18 extends transversely on the outside of the body 2 so as to form a projection 18 cooperating with a notch in the intermediate connecting link 30 as disclosed hereinafter.
A trigger 24 is pivotally secured to the body at 25 and includes a head 24 engaging a shaped groove in the body 1. Said head 24 forms at its end a permanent bearing for a thrust-exerting ball 27 housed in the axial bore of a sleeve 26 screwed longitudinally into the front end of the pistol body 1. The pressure of a coil spring 27 urges the ball 27 towards the trigger head 24 is adjusted by a screw 28 screwed inside the tapped bore of the sleeve 26 so as to provide for the adjustment of the pressure exerted on the trigger 24 according to the load prescribed for competition purposes.
Furthermore the sleeve 26 is locked by means of a transverse screw 29 screwed also into the body 1. As in the case of the screw 22. the screw 28 is provided with outer longitudinal grooves which cooperate as illustrated in FIG. 6 with the screw 29 so as to prevent an undesired release of the screw 28. Thus, it is apparent that the adjustment of the pressure exerted on the trigger 24 is wholly independent of the means returning the sear into its inoperative position.
The head 24 of the trigger 24 carries a transverse sleeve 32 in which is fitted a stud 30 rigid with an intermediate connecting link 30 whereby the latter may be shifted longitudinally.
Said lateral connecting link 30 (FIG. 1) is provided at its rear end with a U shaped notch 30 engaging the lateral projection 18 on the sear 18 so as to ensure the coupling of the latter. The length L of the notch 30 is however larger than the length D of said projection 18 so as to allow the connecting link 30 to execute an adjustable idle longitudinal stroke without carrying along with it the sear 18.
It should be noted that the permanent contact between the bottom of the notch 30" and the projection 18 is obtained by a thrust in the direction of the arrow F as provided by a hairpinshaped spring 31 secured to the sleeve engaging the pivot of the trigger 24, the upper resilient section of the spring 31 bearing against a transverse tongue 30" formed in the front section of the connecting link 30.
It is apparent than when firing. a suitable gradual effort exerted on the trigger 24 ensures a shifting of the intermediate connecting link 30 which executes an adjustable idle stroke at the end of which the link drives the sear 18 against the action of the spring 20 whereby the nose on it escapes the hammer notch 11.
The hammer is thus released and rocks so as to impinge against the striker. the movable breech block being of course then in its operative position.
Such an idle stroke for the connecting link 30 may be adjusted through action on the front abutting point of the trigger 24, said point being defined by the inner end of a screw 33 extending obliquely through the front end of said trigger so as to engage adjustably the groove registering wit it in the body I. Said screw 33 is again provided with outer longitudinal grooves cooperating with a positioning ball. Similarly. the outer rear end of the trigger 24 is provided with an adjustable stop so as to allow a pivotal motion of a predetermined amplitude, said stop being constituted by a screw 34, the tip of which is adapted to also engage the cooperating groove in the body 1.
In order to prevent an uninterrupted firing occurring if the marksman leaves his finger on the trigger 24, it is necessary for the connecting link 30 to sink automatically whenever the movable breech block 3 is shifted, this being provided by the engagement of a boss 30 on the upper surface of the connecting link 30 with a shaped longitudinal groove formed on one side of the movable breech 3. Said release in the direction of the arrow F1 disengages the notch 30 formed in the link from the projection 18 on the sear and this allows automatically the sear 18 to be reset each time the hammer recedes after firing. For the operative position of the movable breech block 3, the boss 30 on the upper surface of the connecting rod engages a notch 3 in the breech block so as to interengage said breech block and connecting link. The manually controlled safety lever 19 pivoting at 19 coaxially with the sear 18 carries at its upper end a projection l9 (FlG. 5) adapted to shift the connecting link downwardly so as to release the latter by disengaging the notch 30 in said link with reference to the projection 18. Said lever is held fast in either of its extreme positions by means of positioning balls which are not illustrated.
Underneath the micrometric sight. an axial abutment rod 36 (FIG. 1) is fitted the flat free end of which registers with the hammer 11 so as to limit the path followed by the latter when set in the position illustrated in interrupted lines in FIG. 1. Such an arrangement is of interest for blank firing when the cartridge is not ignited. Real firing is executed of course after an unscrewing of the abutment rod 36 which is also braked and positioned by a spring-urged ball, as shown in FIG. 1.
According to our invention there is rigidly secured to one half of a grip 37 of the pistol, whether on the righthand side or on the left-hand side a plate 38 provided with a T-shaped recess forming an annular slideway for a link 39 frictionally held in an adjusted position by a screw 40. This link is rigid with a cylindrical locking nut 41. This provides means for a vertical adjustment of a tang 43 with reference to the grip section 37.
