Description
1 12~ZgO4 The present invention generally relates to automatically feeding hand weapons, for instance machine pistols and similar, automatic or semi-automatic weapons, and more particularly to an improved apparatus for operating the bolt in such hand weapons.
In order to set such weapons into shooting condition the bolt must be stretched to a shooting position. Most automatically feeding weapons known today are disadvantageous as concerns the way of actuating the bolt from outside the bolt or the locking bolt etc.
The most usual and most simple embodiment of an apparatus for operating the bolt consists of a fixed or releasable handle which is mounted in the bolt and which pro~ects through a slot of the receiver of the weapon and which during the shooting moves reciprocally together with the bolt. This apparatus is disadvantageous in several respects. The slot for the handle, which extends over a substantial part of the length of the receiver reduces the strength of the receiver; the handle which during shooting moves reciprocally may irritate the marksman or may ln the worst case hurt the marksman, and it may get caught in ad~acent ob~ects; an enemy who is let to close to the marksman may with a quick and well positioned grab in front of the handle make further shooting impossible; since the handle is generally placed on the right side or on the left side the weapon can not be handled like good with both hands but is mainly intended either for right handed or for left handed marksmen respectively;
if the handle ls placed on top or the receiver it often impedes the mounting of optical sights etc; the unprotected slot for the handle allows snow, water, sand and other impurities and not wanted materiae to enter the receiver, which may cause stop of fire or may damage the weapon; since the handle must, for space reasons, ~e made rather small it may under some circumstances be difficult to get a good grip of the handle and to complete a correct loading movement, for instance when using coarse gloves, at cool weather etc, and this may lead to accidental fire or it 129Z~304 may prevent the intended firing; accidental fire also may appear if the projecting handle gets caught in some part of the equipment of the marksman or in any adjacent ob~ect.
A number of more or less complicated constructions have been suggested, which may solve some of the above mentioned problems but which still involve some other ones of the said disadvantages and problems.
The present invention overcomes all of the above mentioned problems and disadvantages in known hand weapons of automatic or semi-automatic type and provides simple and effective apparatus for actuating the bolt from outside the weapon, whereby, in front of all, the previously usual slot of the receiver and the handle pro~ecting through said slot is eliminated, and which is mainly characterized in that the actuation means for the bolt is a bar which protects through a bore in the rear wall of the receiver.
Thus according to the present invention there is provlded in an automatically feeding hand held firearm having a receiver including a back wall, a bolt supported for reciprocal movement withln the receiver between cocking and flring positions, a recoil spring for biasing the bolt position toward its firing position, and means for moving the bolt to its cocking position including a bolt actuating rod pro~ecting rearwardly beyond the back wall and movable between first and second positions corresponding respectively to the firing and cocking positions of the bolt, the bolt being movable between its firing and cocking positions independently of the movement of the bolt actuating rod when the bolt actuating rod is in its first position, the improvement comprising said bolt actuating rod pro~ectlng rearwardly from said receiver through a bore ln said back wall, and latching means for releasably retaining said bolt actuating rod in its first position including a rear recess in the rear end portion of said bolt actuating rod for receiving therein an associated bore defining portion of said rear wall when said bolt lZ~2~04 actuating rod is in its first position to retain said bolt actuating rod in fixed position relative to said rear wall, and means for biasing said bolt actuating rod toward said bore defi;ning portion. Suitably sald bolts have a groove therein, said recoil spring is received on and guided by said bolt actuating rod, and said recoil spring and said bolt actuating rod are received within said groove. Desirably said means for moving sald bolt to its cocking position includes a sling ring connected to the rear end portion of said bolt actuating rod for connecting lo a sling thereto whereby the sling may be employed to release said latching means and move said bolt actuating rod from its first position to its second position to cock said firearm.
In one embodiment of the present invention said bolt actuating rod is slidably engaged with said bolt and has a rearwardly facing shoulder engaging said bolt when said bolt is in its firing posltion and sald bolt actuating rod is in its first posltion. Desirably said bolt actuating rod has an elongated front recess therein defining said shoulder and said bolt carries a cross-pin which extends transversely of said front recess and is engaged by said shoulder when said bolt is in its firing position and said bolt actuating rod is in its first position.
In another embodiment ofthe present invention the firearm includes means for biasing said bolt actuating rod toward its first position. Desirably said recoil spring is received on said bolt actuating rod and comprises said means for biasing said bolt actuating rod toward said first position. Suitably a recoil spring guide rod receiving said recoil spring thereon and said means for biasing said bolt actuating rod comprises a return spring received on said bolt actuating rod.
In a further embodiment of the presemt invention said latching means includes a bushing slidably received on said bolt actuating rod, means for maintaining said bushing in slidlng engagement with said back wall, and a spring acting upon said bushing.
- 2a -~292~04 Suitably said means for maintaining said bushing comprises means for biasing said bolt actuating rod to its first position.
Desirably said means for maintaining said bushing comprises said recoil spring. Suitably the further improvement comprising a recoil spring guide rod receiving said recoil spring thereon and said means for biasing said bolt actuating rod comprises a return spring received on said bolt actuating rod.
Further characteristics of the invention will be evident from the following detailed specification in which reference will be made to the accompanying drawings in which:
Figure 1 is a side view, partly ln a cross section, of an automatic hand weapon formed with the apparatus according to the invention for operating the bolt it a loading movement;
Figure 2 is a side view of a detail of the apparatus according to the lnvention; and Flgures 3 and 4 are cross sectlonal views, in a larger scale, along lines III-III and IV-IV respectively of Figure 2.
The automatic weapon shown in figure I is a machine plstol, - 2b -1A `~`~
lZ9Z904 l;he main design of which is of known type and will not be described in detail. The parts of the weapon which are important and interesting to the ;nvention are the receiver 1, in which the bolt 2 is slidably guided between a rear loading position (not illustrated) and a front restinq and firing position respectively, a recoil spring 4 and a recoil spring bar 5.
At the upper part the bolt 2 is formed with a longitudinal slot or a bore 3 leaving a space for a recoil spring 4, which is guided on a recoil spring bar 5. The front end of the recoil spring 4 is in contact with a bolt sleeve 6 which is secured to the bolt 2. The rear end of the recoil spring 4 is in contact with a bushing 8, which, in turn, slidably rests against the back 9 of the receiver. The recoil spring 5 is substantially cylindrical and it is adapted to project through a cylindrical bore 10 of the back 9.
As best shown in figures 2-4 the recoil spring bar 5 is formed with two recesses, namely a relatively long bottom/front recess 11 and an upper recess 12 adjacent the rear end of the recoil spring bar 5.
The bottom/front recess 11 extends from a place adjacent the front end of the recoil spring bar 5 and within the area of the bolt sleeve 6 a distance back which is at least as long as the operating distance of the bolt 2 from its rear reverse position to its front firing or resting position. The said elongated recess 11 has a depth which is the same as or slightly larger than the height of a cross bolt 7, so that the bolt together with the bolt sleeve 6 and the cross bolt 7 can move freely between its rear reverse position and its front firing or resting position.
The rear recess 12 extends radially a distance corresponding to about half the radius in the bar 5, and the axial length thereof is slightly larger the thickness of the material of the back 9 of the receiver, so that it can be locked against said back in that the recoil spring bar 5 is pressed upwards, whereby a part of the back is recelved in the recess 12. In order to provide such pressing upwards of the reco~l spring bar 5 the back 9 of the ~292~04 receiver 1 is formed with a pin or an arm 13 which is pressed uppwards by a spring 14 into contact with the slidable bushing 8, and which is preferably guided in an annular groove 15 of the bushing.
As evident the apparatus is formed so that the bolt can be moved back from the front firing and resting position, shown in figure 1, in that the rear end of the recoil spring bar 5 is pressed downwards so that the rear upper recess 12 is let free from the upper edge of the bore 10 of the back 9, whereupon the recoil spring bar 5 is pulled back together with the bolt 2 which during this movement is kept secured by the cross bolt 7. The bolt is pulled back as far as to its charge position, in which position it is hooked by the trigger bar (not shown). Since the front lower recess 11 is made sufficiently long the recoil spring can freely be expelled as far as to its illustrated front position where it is locked in that the spring 14 via the arm 13 and the bushing 8 presses the rear end of the recoil spring bar 5 upwards so that a part of the receiver back g is received in the recess 12. The recess 12 thereby guarantees that the recoil spring bar 5 does not un-intentionally, for instance due to friction, follow the bolt in its movement rearwardly when the weapon is fired.
After the bolt has been tensioned, as described above, the recoil spring bar 5 is thus returned to its front position and remains in this position as long as firing goes on and until the rear end of the bar 5 is once again pressed down for once again tensioning the bolt.
In order to make is possible to actuate the recoil spring bar from outside it is necessary that the projecting rear part thereof is formed with a hold, and this may be a T-formed or ring-formed finger hold. In the illustrated case the hold is a ring 16, which provides an attachment part for the sling ring 17 of the weapon.
This means that the weapon sling is used to actuate the recoil spring bar for charge-tensioning the bolt.
The correct manipulation of the weapon is the following:
1. Get hold of the weapon sling adjacent the sling ring 17 lZ~Z904 and press the recoil spring 5 downwards, so that the recess 12 gets out of engagement with the receiver back 9;
In order to set such weapons into shooting condition the bolt must be stretched to a shooting position. Most automatically feeding weapons known today are disadvantageous as concerns the way of actuating the bolt from outside the bolt or the locking bolt etc.
The most usual and most simple embodiment of an apparatus for operating the bolt consists of a fixed or releasable handle which is mounted in the bolt and which pro~ects through a slot of the receiver of the weapon and which during the shooting moves reciprocally together with the bolt. This apparatus is disadvantageous in several respects. The slot for the handle, which extends over a substantial part of the length of the receiver reduces the strength of the receiver; the handle which during shooting moves reciprocally may irritate the marksman or may ln the worst case hurt the marksman, and it may get caught in ad~acent ob~ects; an enemy who is let to close to the marksman may with a quick and well positioned grab in front of the handle make further shooting impossible; since the handle is generally placed on the right side or on the left side the weapon can not be handled like good with both hands but is mainly intended either for right handed or for left handed marksmen respectively;

Suitably sald bolts have a groove therein, said recoil spring is received on and guided by said bolt actuating rod, and said recoil spring and said bolt actuating rod are received within said groove. Desirably said means for moving sald bolt to its cocking position includes a sling ring connected to the rear end portion of said bolt actuating rod for connecting lo a sling thereto whereby the sling may be employed to release said latching means and move said bolt actuating rod from its first position to its second position to cock said firearm.

In a further embodiment of the presemt invention said latching means includes a bushing slidably received on said bolt actuating rod, means for maintaining said bushing in slidlng engagement with said back wall, and a spring acting upon said bushing.
- 2a -~292~04 Suitably said means for maintaining said bushing comprises means for biasing said bolt actuating rod to its first position.
Desirably said means for maintaining said bushing comprises said recoil spring. Suitably the further improvement comprising a recoil spring guide rod receiving said recoil spring thereon and said means for biasing said bolt actuating rod comprises a return spring received on said bolt actuating rod.
Further characteristics of the invention will be evident from the following detailed specification in which reference will be made to the accompanying drawings in which:
Figure 1 is a side view, partly ln a cross section, of an automatic hand weapon formed with the apparatus according to the invention for operating the bolt it a loading movement;
Figure 2 is a side view of a detail of the apparatus according to the lnvention; and Flgures 3 and 4 are cross sectlonal views, in a larger scale, along lines III-III and IV-IV respectively of Figure 2.
The automatic weapon shown in figure I is a machine plstol, - 2b -1A `~`~
lZ9Z904 l;he main design of which is of known type and will not be described in detail. The parts of the weapon which are important and interesting to the ;nvention are the receiver 1, in which the bolt 2 is slidably guided between a rear loading position (not illustrated) and a front restinq and firing position respectively, a recoil spring 4 and a recoil spring bar 5.
At the upper part the bolt 2 is formed with a longitudinal slot or a bore 3 leaving a space for a recoil spring 4, which is guided on a recoil spring bar 5. The front end of the recoil spring 4 is in contact with a bolt sleeve 6 which is secured to the bolt 2. The rear end of the recoil spring 4 is in contact with a bushing 8, which, in turn, slidably rests against the back 9 of the receiver. The recoil spring 5 is substantially cylindrical and it is adapted to project through a cylindrical bore 10 of the back 9.
As best shown in figures 2-4 the recoil spring bar 5 is formed with two recesses, namely a relatively long bottom/front recess 11 and an upper recess 12 adjacent the rear end of the recoil spring bar 5.
The bottom/front recess 11 extends from a place adjacent the front end of the recoil spring bar 5 and within the area of the bolt sleeve 6 a distance back which is at least as long as the operating distance of the bolt 2 from its rear reverse position to its front firing or resting position. The said elongated recess 11 has a depth which is the same as or slightly larger than the height of a cross bolt 7, so that the bolt together with the bolt sleeve 6 and the cross bolt 7 can move freely between its rear reverse position and its front firing or resting position.
The rear recess 12 extends radially a distance corresponding to about half the radius in the bar 5, and the axial length thereof is slightly larger the thickness of the material of the back 9 of the receiver, so that it can be locked against said back in that the recoil spring bar 5 is pressed upwards, whereby a part of the back is recelved in the recess 12. In order to provide such pressing upwards of the reco~l spring bar 5 the back 9 of the ~292~04 receiver 1 is formed with a pin or an arm 13 which is pressed uppwards by a spring 14 into contact with the slidable bushing 8, and which is preferably guided in an annular groove 15 of the bushing.
As evident the apparatus is formed so that the bolt can be moved back from the front firing and resting position, shown in figure 1, in that the rear end of the recoil spring bar 5 is pressed downwards so that the rear upper recess 12 is let free from the upper edge of the bore 10 of the back 9, whereupon the recoil spring bar 5 is pulled back together with the bolt 2 which during this movement is kept secured by the cross bolt 7. The bolt is pulled back as far as to its charge position, in which position it is hooked by the trigger bar (not shown). Since the front lower recess 11 is made sufficiently long the recoil spring can freely be expelled as far as to its illustrated front position where it is locked in that the spring 14 via the arm 13 and the bushing 8 presses the rear end of the recoil spring bar 5 upwards so that a part of the receiver back g is received in the recess 12. The recess 12 thereby guarantees that the recoil spring bar 5 does not un-intentionally, for instance due to friction, follow the bolt in its movement rearwardly when the weapon is fired.
After the bolt has been tensioned, as described above, the recoil spring bar 5 is thus returned to its front position and remains in this position as long as firing goes on and until the rear end of the bar 5 is once again pressed down for once again tensioning the bolt.
In order to make is possible to actuate the recoil spring bar from outside it is necessary that the projecting rear part thereof is formed with a hold, and this may be a T-formed or ring-formed finger hold. In the illustrated case the hold is a ring 16, which provides an attachment part for the sling ring 17 of the weapon.
This means that the weapon sling is used to actuate the recoil spring bar for charge-tensioning the bolt.
The correct manipulation of the weapon is the following:
1. Get hold of the weapon sling adjacent the sling ring 17 lZ~Z904 and press the recoil spring 5 downwards, so that the recess 12 gets out of engagement with the receiver back 9;
2. Pu11 the recoil cpring bar 5 rearwardly until the bolt has become hooked by the trigger bar or a corresonding holding means;
3. Press the recoil spring bar 5 back to its front locking position.
If the weapon in question is of the type that does not shoot with the bolt hooked in its rear position but with the bolt in the front position the recoil spring bar is pulled to its rearmost position and is then let free. The recoil spring thereby presses both the bolt and the recoil spring bar to its front position.
If, for instance due to lack of time, the recoil spring bar 5 should not be returned from its rear position to its front locking position after the bolt has been tensioned the bolt 2 will, upon firing the first shot, bring the recoil spring bar 5 to its front locking position, in which position the recoil spring bar is locked in that the rear recess 12 engages the receiver back 9.
In an alternative embodimènt of the invention the above described recoil spring bar can be completed with a separate bar, preferably having a separate advancing spring, which bar is always, by its own activity, returning the recoil spring bar to its front locking positing av soon as the sling is let free.
