EJECTOR MECHANISM OF SPORTS AND HUNTING GUNS

one

The invention relates to sporting and hunting shotguns and is an ejector mechanism for automatically ejecting liners from the chamber of barrel when fired when the barrels are tilted.

In the known ejector mechanisms, liners are ejected only after the trigger and trigger mechanism has been pulled from a platoon. In other cases of opening the trunks, extractors are pulled out.

In this case, to turn off the ejector (for example, when firing cartridges with metal sleeves) in known mechanisms, a translator with a tooth is used, which requires an instrument in the form of a hammer or similar object to install.

This creates certain inconveniences in the operation of guns with such mechanisms and reduces the strength of the main part - the translator of the hammers.

In order to provide ease of switching off and on in the proposed mechanism, the feeder is equipped with a semicircular recess, which includes an elliptical cam made on the end of the translator roller, equipped with two opposite holes for the clamp and having a flag-translator at the outer end.

FIG. 1 shows a longitudinal section of a gun at the location of an ejector mechanism with a section along A-A; pas figs. 2 - plan view of a block with a feeder, a cam roller of the translator and a clamp (the ejector is on - the feeder is in the front position); in fig. 3 - the same (the ejector is switched off - the feeder is in the rear position); pas figs. 4 is a section along BB in FIG. 2; pas figs. 5 is a section along BB in FIG. 3

In coupling 1 (Fig. 1) with two trunks there is a hole 2, in which two extractors 3 and 4 are placed, separately working on the right and left trunks and limited in the longitudinal direction by a pin 5. Between the trunks are placed a rack 6, on which by means of a latch 7 and the hinge 8 is held by the forearm 9. In the radius part of the hinge on the axis 10 there are fortified two courses 11 of the ejector, spring-loaded two springs 12, located in the recess 13 of the tide 14 of the hinge. In the lateral grooves of the pads 15, two spring-loaded platformers 16 are installed, interacting with the projections 17 of the hammers 18 of the firing mechanism. In the front part of the pad there is a cam feeder 19 having in the lower cavity a sample of 20 (Fig. 4) for the axis of the joint 21 and a recess 22 for the cam roller 23 (Fig. 2).

The outer end of the roller has a flag 24 for rotating and fixing the roller by means of holes 25 and 26 on the spring-loaded sleeve 27.

When the flag 24 is set in the rear position, the roller 23 is fixed by the socket 27 and the hole 25 (Fig. 2). At the same time, its ellipsoid cam surface (Fig. 4) interacts with the recess 22 of the feeder 19, which is moving forward under the action of its spring, and blocks it in this position. The feeder 19 in the forward position at each closing of the barrels after their reclining interacts with the ejector triggers 11, turning them on the axis 10 in the direction of pressure of the springs 12. Then with each tilting of the trunks after firing, the trigger 11 turned by the platformers 16 at the end of the movement hit the extractors 3 and 4 by throwing the liner away.

If it is necessary to reject the mechanism from the operation, the flag 24 with the trunks folded back is moved to the front position, fixing the roller 23 on the insert 27 by the hole 26 (Fig. 3). In the process of turning, the recess 22 of the feeder 19 (Fig. 5) is released from the blocking by the roller 23, enabling the feeder 19 to move the gun in the slots of the pad.

After that, when closing the barrels of the surface d of the cocks 11, acting on the protrusion of the feeder 19, the latter is moved back, as a result of which the cocks 11 cannot turn on the axis 10 for cocking and pumping of the springs 12 and remain in the uninitiated position.

Now, when the trunks are tilted away after firing, the coppersmiths 16 pass by the unreleased hammers 11, and the feeder 19 performs the usual extension of the extractors 3 and 4.

In order to return to the ejection mode of operation of the mechanism, the flag 24 is again moved to the rear position.

Subject invention

An ejector mechanism of sporting and hunting rifles, consisting of extractors, cocksuppers with springs, a cam feeder of cocks with a spring, and coppers, characterized in that, in order to provide easy switching off and on of the mechanism, the feeder is equipped with a semicircular notch, which includes an ellipsoid cam made at the end of the roller of the translator, supplied with two opposite holes under the fixer and having a flag-translator lever at the outer end.
