"Cocking * and ejection mechanism for hunting rifles"

The present invention relates to a tensioning and Ejection mechanism for hunting rifles.

If the quality is good, they are. considered rifles relatively expensive »This fact arises to a large extent from the number of extremely precise settings that are made when manufacturing, assembling and readjusting your clamping and Ejection mechanism are required. As a result, their production remains characterized by purely manual work. Of the The purpose of the present invention is to provide a solution by which the industrial production of quality rifles of the type under consideration is made possible, by reducing the number of conventional adjustments on a process »For this purpose a tensioning and ejecting mechanism is proposed with, for each barrel, the following Combination: a stopcock; a tension rod leading through the receiver, one end of which with the aforementioned The hammer comes into contact and the other end is intended to do so is, with one of the profile-shaped ends of a rotatable on the front

the shaft attached clamping lever interlock} a rotatable attached to the fore-end, equipped with a return spring **: μπα. Ejector stud j, which can be displaced via the other end of the aforementioned clamping lever, is an ejector cock equipped with a return spring and controlled by the aforementioned ejector stud; and a Extractor-ejector controlled by a slide in which one approach is located in the path of the aforementioned ejector tap.

In a mechanism of this type, only one adjustment of the aforementioned tie rod is required, which is a considerable one Represents simplification.

For clarification, the invention is described below, with reference to the accompanying drawings:

The rifle shown in Figure 1 has two barrels 1 and 2 one above the other, a fore-end 3 below

the lower barrel 2, this forearm immediately above the The rear of the fore-end nose 5 rests against a receiver 4. the vorerwäfiiite receiver 4 rotates on a hinge whose axis the center of part 6 leads.

There is an impact and ejector jig for each barrel intended.

Each of these devices comprises one, rotatable on eight on the fore-end 3 attached clamping lever 7. The profiled The outer end 9 of this lever 7 can work together with the beveled end 10 of a tensioning rod 11 which passes through the receiver leads and axially movably seated in this latter. The other end of the aforementioned rod 11 is of a suspension 12 against an extension 13 of the hammer 14 rotatably attached to 15 returned, which is pushed back by one of the suspension 18 Grain 17 is forced to the ignition cone 16. Tap 14 can in its cocked position are held by sear 19, in a manner known per se by actuation the trigger 20 can be released. The outer end 21 of the clamping lever 7 comes into contact with an ejector lug 22, which is rotatably attached to 23 on the fore-end and constantly through a Suspension 24 is forced in the direction of its high position.

An ejector tap 25, which is rotatably attached to the fore-end, has a projection 27, which by the aforementioned Ejector lug 22 can be engaged, as well as via a nose 28 with respect to an extension 29 of a slide 30 which actuates the extractor 31. Hahn 25 is constantly occupied by a center punch 32, which is pushed back by a suspension 33.

The aforementioned approach 29 has an arm 34,

309830/0391

which is inclined downwards and between two projections 3 5 and 36, respectively the receiver 4 is indented. The opening of the weapon is controlled by the Actuation of a key 37 allows.

The device described above functions essentially as follows.

The weapon, ready to fire, is in the position shown in Figure 1. The hammer 14 is cocked and is held by the trigger 19. The outer end 10 of the rod 11 is not indented into the outer end 9 of the clamping lever 7, through the action of the suspension 12. The approach 27 of the Auewerferhahne is in front of the ejector cleat 22, while its nose 28 with the approach 29 of the slide 30 in Touch device.

After the launch, the hammer It hits the Ignition cone 16 to lie after he pushed the rod 11 back has that its end 10 engages with the end 9 of the clamping lever 7 (Figure 2 and 3).

When the weapon is opened, the relative angular movement of the fore-end 3 and the receiver 4 results in a first phase (Figure 4-5):

1. The pushing back of the tension rod 11 infoige the intermediate point of the outer end 9 of the tension lever 7, as Result of the hammer IH is cocked j

2. a slight rotary movement of the lever 7, the end 21 of which pushes the sear 22 back against the suspension 24;

3. The pushing back of the arm 34 through the shoulder 35 the receiver, which causes the sleeves 38 and 39 to be pulled out.

In the last opening phase (Figure 6) it sinks The outer end 21 of the lever 7 continues to push the trigger

309830/0391

2282681

stud 22 even further back, this being the approach 27 of the Ejector tap 25 releases. This latter is then pushed back by the grain 3 2 under the action of the suspension 3 3. the Nose 28 pushes the approach 29 back violently, causing a corresponding displacement of the extractor 31 and the ejection of this controlled cartridge 3 8 brings with it. This displacement of the extractor is limited by the approach 36 of the receiver which as Stop for the outer end of the arm 34 acts (Figure 6). When the weapon is closed, the extension 36 forces the arm 34 back, which causes the retraction of the extractor 31 and the pushing back of the cock 25 in its original position. The suspension 24 ensures the return of the sear 22 and the pivoting of the lever 7 into its respective starting position as shown of Figure 1.

It should be noted that in the mechanism described above, only one component requires fine adjustment: the tension rod 11. Otherwise, the ejection cannot take place until the receiver allows the sleeves 38 and 39 free passage, ie from a minimum distance d ab (Figure 5). A fine adjustment of the ejection time is made possible by a screw 40 _? which leads through the ejector lug 22 and the end 41 of which is touched by the outer end 21 of the clamping lever 7 when the latter pushes back the aforementioned ejector lug. The release of the ejector tap 25 can thus be set precisely and quickly.

Of course, changes of various kinds can be made to the device described above can be made without thereby to exceed the scope of the invention.
