CARTRIDGE MAGAZINE FOR POWER TOOLS The present invention relates to a magazine for cartridges which is used in power tools and constitutes a means for simplifying'the reloading of the tool.
BACKGROUND OF THE INVENTION In most shooting implements the loading procedure is cumbersome and time-consuming, since both pin or bolt and propellant charge has to be applied in the implement, before it is ready for shooting. Certain attempts have been made earlier to automate parts of the procedure, but as a consequence the implement became complicated and expensive to manufacture. If the demand for automation of the procedure is not higher than that certain manipulations might be forestalled, a cheap and simple device can nevertheless achieve a considerable simplification of the procedure.
SUMMARY OF THE INVENTION In accordance with the present invention a device on a cartridge magazine is presented, by virtue of which the loading of the tool with a propellant charge is semiautomated and a great number of such charges are stored in this magazine in readiness for a rapid reloading of the tool. The magazine is arranged so that it can readily be exchanged in a holder on the tool and by using several magazines a rapid and simple loading is made possible without the loss of time brought about by the filling up of the magazine. These advantages, and possibly also others are obtained in accordance with the invention by a design of a cartridge magazine in which the cartridges are contained behind one another in a channel and the part of the magazine which constitutes the channel is tiltable between two end positions, in one of these the channel communicates with a cartridge chamber arranged in the tool in the inner end of the barrel of the tool.
BRIEF DESCRIPTION OF THE DRAWINGS Some examples of the realization of the magazine in accordance with the invention are described in the following with reference to the enclosed drawing, which shows in FIG. 1 a tubular magazine with holder on a power tool;
FIG. 2 a drum magazine intended for the same holder as the magazine in FIG. 1;
FIG. 3 a variant of a drum magazine together with holder for the same;
FIG. 4 the holder for the magazine in FIG. 3;
FIGS. 5 and 6 a locking and guiding device for one of the magazines;
FIG. 7 a drum magazine with a pivoted loading tube.
DETAILED DESCRIPTION OF THE DRAWINGS On the drawing is shown a power tool which is operated with cartridges 2 which are introduced into the cartridge chamber 3 one by one and fired. The tool is intended originally to be loaded with one cartridge directly into the cartridge chamber, to be closed and fired, whereupon the loading procedure is repeated. This longwinded procedure which comprises taking the cartridges one by one from a box or the like and inserting them into the cartridge chamber, is eliminated by arranging a cartridge magazine 4, 5 or 6, placed in FIG.
1 on top of the tool and in FIGS. 3 and 4 at the side of the same. The drawings also indicate that the tool must have a special design to allow the employment of such a cartridge magazine. The tool is shown in pulled out condition, that is to say its barrel 7 with driving piston inside it has been pulled out of the body 8 of the tool to a loading position, the cartridge chamber 3 being laid bare in a loading opening 9 in the body.
The solution in principle of the problem to contrive a cartridge magazine in accordance with the invention will now be shown and described in connectioon with FIG. 1. Above the rear portion of the body 8 a holder 10 is fixed which has a transverse axle 11 which carries the tubular cartridge magazine 4. This is provided on the underside with a transverse notch 12 (FIG. 2) in which there is a spring catch, so that the magazine can be mounted on the axle 11 and be maintained on the same by means of the notch and the catch. In the holder 10 is also a spring 13 which presses on the magazine, so that the same is maintained in raised position (broken lines in FIG. 1). At the rear end of the magazine is a screw cap 14 which covers the rear opening of the magazine. When the cap is removed cartridges 2 can be filled in through this opening.
The loading of the tool with a cartridge 2 takes place in such a way, that the barrel 7 is pulled into the loading position (shown) and the front end of the magazine is pressed down by hand into the loading position at the same time as the tool is inclined somewhat forwards. The cartridges will then under their own weight fall downwards/forwards in the magazine and the frontmost cartridge enters into the cartridge chamber 3. The magazine is then raised again into the position shown in broken lines by the spring 13, but not higher than that the cartridges in the tube are prevented by the front wall 15 in the loading opening from falling out. The tool is then closed up and after pushing a pin into its mouthpiece 16 it is ready for shooting. A tubular magazine of the type as shown in FIG. 1 holds about 15 cartridges and, as mentioned earlier, can readily be filled up when required.
A substantially increased space for cartridges is obtained by realizing the magazine in accordance with FIG. 2. This realization has the shape of a drum 17, comprising a number of axial channels 18 accomodating the cartridges 2. The drum is located in a housing 19 from which extends a tube 20 in a forward direction. Underneath the housing is a socket 21 for the holder 10. The drum can be rotated inside the housing and has defined angular positions which each correspond to a connection of any one of the channels 18 to the tube 20. The cartridges in the channel connected are then able to drop through the tube towards the cartridge chamber 3, when the magazine is mounted on the tool. The drum can be extracted from the tool and either be filled up again with new cartridges or be substituted by a full magazine. The loading procedure for the rest is the same as that described above in connection with the magazine in accordance with FIG. 1.
The design of the body with loading opening as shown on the drawing also allows the arrangement of a cartridge magazine 6 at one side of the loading opening, such as shown in FIGS. 3 and 4. This magazine consists of a drum 22, supported in a bracket 23, which in its turn is set up in a holder 24 on the tool. The bracket is mounted on the holder so that it can be folded down and extend in collapsed position into the loading opening, while it is normally held in the position as shown by a helical spring 25. In the front part of the bracket is a hole 26 to which can be connected every one of the channels 18 by rotation of the drum. The cartridges in the channel connected to the hole can then fall forwards towards the cartridge chamber 3, when the magazine is held in folded down position. In raised position (shown) the cartridges are held in position in the channel, since the hole 26 is then covered by the front wall 15, as mentioned before in respect of the magazine 4 and 5. The drum 22 can be removed from the bracket by pulling the same a little apart, so that a pivot 27 projecting on the drum can slide out of the hole 28 in the bracket where it is journalled. A drum filled with cartridges is put in position by pulling the bracket away, so that a pivot 27 in each end of the drum can slide into the corresponding hole 28 in the bracket, whereupon the pivots thanks to the restoring spring force in the bracket, are retained in the holes.
The use of the magazine 6 is fully analogous to that described previously in connection with magazines 4 and 5, that is to say, the tool is loaded by pulling out the barrel to the position shown, inclining the tool forwards, folding the magazine down into the loading opening, so that a cartridge has the opportunity of dropping into the cartridge chamber and, after the magazine has reverted to its normal position, the barrel is pushed back in again.
A device apt to facilitate still further the loading procedure is shown in FIGS. and 6. In FIG. 5 the device is shown in rest position and in FIG. 6 in loading position. The cartridge tube 4 is the same as shown in FIG. 1, except that it has been provided in this embodiment with a locking and controlling device, by means of which the centering of the magazine in loading position takes place, and the cartridges are retained when the magazine is in rest position. As can be seen from FIGS. 5, 6 the magazine has a body 29 with a holder 30, fixed on an axle on the upper side of the tool. Between the body and the tube 4 a leaf spring 31 is inserted with forward tension. Its front end has a double band 32 and the bottom part of this is located in rest position (FIG. 5), thanks to the clamping of the spring, in front of the mouth of the tube, thus preventing the cartridges 2 from dropping out of the tube.
In loading position (FIG. 6) the spring and the front end of the body constitute a guiding device for the tube. This device is suitable for tools which have a cartridge chamber somewhat drawn back from the barrel, such as shown in FIG. 6. The cartridge chamber is located in a plug 33 in the rear end of the barrel and against this plug rest the body and the spring in loading position, so that the mouth of the tube is centered exactly opposite the cartridge chamber. The cartridges with which the tool is loaded can then drop freely into the cartridge chamber.
A still further embodiment of a magazine according to the invention is shown in FIG. 7. On the rear portion of the tool a housing 34 is fastened and its inner cylindrical spacing is adapted to accomodate a drum 17 provided with axial channels as described with reference to FIG. 2. The drum can be rotated in the housing, and a spring ball 35 snaps into recesses 36 in the periphery of the drum, when anyone of the channels 18 faces the tube 20, which connects the channel and the cartridge chamber. This tube is pivoted at the front end of the housing by means of a pin 37, which penetrates a lug 38 projecting on the underside of the tube. The tube is usually kept in a raised position by means of a spring 39 secured to the front end of the housing and acting on a knob 40 on the topside of the tube. The front end of the tube can, against the force of this spring, be pushed down to the cartridge chamber, when loading takes place.
The embodiments of the invention described above are preferred realizations. Other realizations and addi tional devices may however come within the scope of the invention, e.g., handles, catches etc. for facilitating the taking in and out of the magazine or the loading movement itself. The tube may also include a spring for the pushing forward of the cartridges. The invention is defined in its entirety in the following claims.
