Description

The invention relates to the automation of self-loading and automatic small arms such as a pistol, submachine gun, machine gun.

As an analogue, one can imagine the automatics of a pistol of the Webley-Scott company Mk 1, 1912 {1,187 p.}. Automation works on the principle of recoil of the barrel with its short stroke. On the rectangular breech of the barrel are placed on top of the locking protrusion and along the side walls of the inclined unlocking, locking protrusions. In the shutter housing there is a rectangular window for removing spent cartridges and where the locking protrusion of the breech barrel is placed when locking the bore. Locking and unlocking of the barrel is carried out using a window to remove spent cartridges and locking protrusion, inclined protrusions of the breech of the barrel and inclined grooves of the pistol frame. Therefore, when the shutter moves backward, the barrel moves simultaneously back and down until the locking protrusion of the barrel exits the window of the shutter casing. At the same time, the line of aiming and throwing changes. This is a disadvantage of this type of automation.

The closest in technical essence or prototype is the automation of the pistol "Walter" R-38 {1,251 p.}. Automation works on the principle of recoil of the barrel during its short course. Locking, unlocking the barrel is carried out by a swinging larva in a vertical plane. At high tide the breech has a cutout to accommodate the locking larva and its spring. The unlocking rod is placed in the tide of the breech of the trunk. The shutter is integral with the casing and there are transverse cutouts for the teeth of the locking larva. The disadvantage of R-38 automation is the complex shape of the larva, many details, their manufacturing accuracy, therefore, sensitivity to pollution, reduced reliability.

The objective of the invention is: while maintaining such advantages of the prototype as the principle of automation, recoil of the barrel with its short stroke, rollback of the barrel along the aiming line, to increase the reliability of automation, offering it from parts of a simple form while reducing their number.

The specified technical result is achieved by the fact that the claimed automation of small arms consists of a larva having a rectangular locking protrusion and a beveled protrusion placed in the beveled groove of the weapon frame. Therefore, the claimed automation consists of one part of a simple form, instead of three of the prototype. Consequently, the reliability of automation will increase, its cost will decrease.

Comparable analysis with the prototype allows us to conclude that the claimed automation of small arms is simpler in design and more reliable in comparison with the prototype. The author is not aware of such a design of automation with linear rollback of the barrel. Therefore, the claimed solution meets the criterion of "novelty."

Comparison of the proposed solutions with the prototype allowed us to identify signs that distinguish the claimed solution from the prototype, which allows us to conclude that the criterion of "Inventive step".

The essence of the technical solution is confirmed by the drawings (Fig. 1, Fig. 2) which show the design options of the inventive weapons automation. In FIG. 1 presents the inventive automation for assembling a pistol type P-38 {1,249-260 pages}, where the locking larva 1 with a rectangular locking protrusion 3 and a beveled protrusion 5 is installed in the beveled groove 8 of the frame 6 of the gun.

The barrel 2 has a groove 4 in the tide of the breech to accommodate a rectangular locking protrusion 3 of the larva 1, and the casing-shutter 7, a transverse cutout 9 for the locking protrusion 3 of the larva 1. When rolling back, the casing-shutter 7 with the barrel 2 and the locking larva 1 - along the axis of the trunk, and larva 1 is simultaneously back and down.

This is a short stroke of the trunk. When the locking protrusion 3 of the larva 1 comes out of the transverse cutout 9 of the casing-shutter 7, the barrel 2 will stop, and the casing-shutter 7 will continue to roll back to the stop. When rolling, only the shutter-casing 7 moves forward to the breech of the barrel 2, which is in the extreme rear position, at this moment the transverse cut-out 9 of the shutter-casing 7 with the groove 4 in the tide of the breech and the larva 1 can move up and forward, barrel 2 with a casing-shutter 7, and they together move forward to the stop.

In FIG. 2 presents the inventive automation for the gun layout type C-96 {1,217-230 pages}, where the locking larva 11 with a rectangular locking protrusion 15 and a beveled protrusion 13 is installed in the beveled groove 16 of the frame 14 of the gun. The barrel with the receiver 10 has a rectangular window 18 in the receiver for placing a rectangular locking protrusion 15 of the larva 11, and the shutter 12 has a transverse cutout 17 for the locking protrusion 15 of the larva 11. The inventive automatics work when assembling a gun of type C-96 like the inventive automatics of a layout gun type P-38.

The inventive automation, using a locking larva with a rectangular locking and beveled protrusion, can be used when assembling a pistol type РГ052, СР-1 {1,454-457 pages} with a return spring on the barrel and a fixed stop of the return spring on the frame. Using an additional, front support on the weapon frame for the movable barrel, the claimed automation can be used in a submachine gun and machine gun. Therefore, the claimed automation is easily adapted to many types of small arms layout, consists in fact of one part of a simple form, instead of three complex ones of the prototype. Consequently, the reliability of automation will increase, its cost will decrease.

To understand the essence of the technical solution proposed by the author, I will give a detailed description of the design and operation of the claimed automation of small arms. In FIG. 1 presents the inventive automation for assembling a pistol type P-38 {1,249-260 pages}, where the locking larva 1 with a rectangular locking protrusion 3 and a beveled protrusion 5 is installed in the beveled groove 8 of the frame 6 of the gun. The barrel 2 has a groove 4 in the tide of the breech to accommodate a rectangular locking protrusion 3 of the larva 1 and the casing-shutter 7, a transverse cutout 9 for the locking protrusion 3 of the larva 1. When rolling back, the casing-shutter 7 with the barrel 2 and the locking larva 1 along the axis trunk back, and larva 1 simultaneously back and down. This is a short stroke of the trunk. When the locking protrusion 3 of the larva 1 comes out of the transverse cut 9 of the casing-shutter 7, the larva 1 reaches the stop, the barrel 2 stops, and the casing-shutter 7 continues to roll back to the stop. When rolling, only the shutter-casing 7 moves forward to the breech of the barrel 2, which is in the extreme rear position, at this moment the transverse cutout 9 of the shutter-casing 7 will combine with the groove 4 in the tide of the breech and the rectangular locking protrusion 3 of the larva 1 will begin to move up and forward, connecting the barrel 2 with the casing-shutter 7, and they together move forward to the stop. The increased gaps between the beveled groove 8 and the beveled protrusion 5 of the larva 1, the rectangular protrusion 3 of the larva 1 and the groove 4 of the barrel 2 and the cutout 9 of the shutter-case 7 will not affect the operation of the claimed automation. Therefore, the claimed automation is slightly sensitive to dust and pollution.

In FIG. 2 presents the claimed automation for assembling a pistol type C-96 {1,217-230 pages}, where the locking larva 11 with a rectangular locking protrusion 15 and a beveled protrusion 13 is installed in the beveled groove 16 of the frame 14 of the gun. The barrel with the receiver 10 has a rectangular window 18 in the receiver for placing a rectangular locking protrusion 15 of the larva 11 and the shutter 12 with a transverse cutout 17 for the locking larva 11 .. When the rollback moves together, the shutter 12, the barrel with the receiver 10 and the locking larva 11 along axis of the trunk, and larva 11 simultaneously back and down.

This is a short stroke of the trunk. When the locking protrusion 15 of the larva 11 comes out of the transverse cut 17 of the shutter 12, the barrel with the receiver 10 will stop, and the shutter 12 will continue to roll back to the stop. When coasting, one bolt 12 moves forward to the breech of the barrel 10, which is in the extreme rear position. At this moment, the transverse cutout 17 of the shutter 12 with the window 18 of the receiver with the barrel 10 is combined and the larva 11 will be able to move up and forward by connecting the barrel with the receiver 10 with the shutter 12, and together they move forward to the stop. The increased gaps between the beveled groove 16 and the beveled protrusion 13 of the larva 11. The rectangular protrusion 15 of the larva 11 and the rectangular window 18 of the barrel with the receiver 10 and the transverse cut 17 of the shutter 12 will not affect the operation of the claimed automation. Therefore, the claimed automation is slightly sensitive to dust and pollution.

The inventive automation, using a locking larva with a rectangular locking worn protrusion, can be used when assembling a pistol type РГ052, СР-1 {1,454-457 pages} with a return spring on the barrel and a fixed stop of the return spring on the frame. Using an additional, front support on the weapon frame for the movable barrel, the claimed automation can be used in a submachine gun and machine gun. Therefore, the claimed automation is easily adaptable to many types of small arms layouts, consists in fact of one part of a simple form, instead of three complex parts of the prototype, it does not impose special requirements on the accuracy of manufacturing parts. Therefore, the range of applications is expanding, the reliability of automation in dusty conditions will increase, its cost will be reduced in comparison with the prototype. What will make the use of the claimed AUTOMATICS OF RUNNING WEAPONS in the production of weapons cost-effective.
