DESCRIPTION
"PISTON CONTROL SYSTEM" PREVENTING THE INADVERTENT
MOVEMENTS OF THE PISTON IN THE MARKSMAN RIFLES WITH
COMPRESSED AIR AND GAS PRESSURE TUBE
Our invention relates to the piston control system, which prevents the air pressure losses resulting from the inadvertent movements such as the piston's hitting the pin for more than one time during the shot or the piston's hitting the pin to open the air way in case of the rifle's being dropped, in the marksman rifles with compressed air and gas pressure tube.
As will be understood from the name, the marksman rifles with compressed air and gas pressure tube work by means of the air and gas, which are compressed into the tube, leaving said tube during the shot, in order to be penetrated into the buckshot in the mouth of the barrel. When the rifle is cocked and trigger is pulled, the piston (6) moves forward with the help of the spring inside, and hits the pin (7) of the air tube. The pin moves backwards for a moment and enables the air valve to open. The air or gas that passes through the opened valve reaches the barrel, to allow the buckshot to exit the barrel. Then the pin returns to its position to close the valve, and the air release stops until the next shot.
Since the movement of the piston (6) may not be controlled in the existing systems, it hits the tube pin (1) more than once when the trigger is pulled. The piston (6), moving forward under the influence of the spring inside, hits the pin (7) and the air valve is opened. While the pin returns to its position by the pressure inside the tube, it hits the piston to cause it move backwards. Meanwhile, the spring inside the piston (6) meets the piston and causes it to hit the pin (7) one more time. This phenomenon is repeated for several times. Hence, even though the buckshot has left the barrel, the unnecessary air release continues. As a result, the buckshot's velocity of
leaving the barrel reduces, and there occurs a decrease in the number of shots.
Another drawback is that as a result of the rifle falling down on the ground or hitting for any reason, the piston (6), due to the back and forth movement property of the spring, hits the tube pin to provide the air release.
All these are undesirable phenomena in a rifle with tube and lead to the complaints from the users.
Taking into consideration these complaints, the inventor has performed studies in this regard, and has formed "Piston Control System" that takes the inadvertent movements of the piston (6) under control and thus eliminates all such problems.
In this system, piston (6) hits the tube pin (7) only once during the shot. Piston is locked by means of the lock sheet (1) to provide its immobility. As it will not be able to hit the tube pin more than once, the unnecessary air release is prevented. In this way, the number of shots becomes greater than the other rifles with the same tube properties and the shot performance is increased; and also the air leaks are prevented, which would form as a result of the fall or the hit of the rifle.
System is formed by an integrity of 4 (four) main parts and 3 (three) supplementary parts.
First of these is the piston lock sheet (1). It is in the shape of (Y). At one of its ends, there are present the projection (10) to which the lock sheet spring (2) is attached and a form (9) which enables the sheet (1) to be lifted and thus the piston (6) to be released during the cocking. In the middle section, there is a hole (8) that provides the mounting to the rifle. The other end is designed to move (11) to the back side of the piston (6) to lock the same.
The second part is the lock sheet spring (2). It operates with one end attached to the slot on the rifle and the other end attached to the projection (10) on the lock sheet (1). It continuously imparts pressure on the lock sheet (1) to help the piston (6) to remain immobile after the shot.
The third part is the lock sheet fixing pin (3). During the assembly, it passes through the hole (8) on the lock sheet (1) to enable it to be fixed to its position on the rifle.
The last part is the sheet shock absorber spring (4), which absorbs the shocks the lock sheet (1) will experience while it locks the piston (6). As seen in Figure 3, two springs are placed on both ends of the fixing pin (3), to enable the sheet to perform spring motion. In this way, the damages to both the lock sheet (1) and the rifle parts are eliminated.
The supplementary parts are the buckshot drive pin (5), piston (6) valve pin (7). All these parts are designed such that they will operate in harmony within the system.
When the cock lever is pulled to start the cocking process for the rifle, the system begins to operate. The buckshot drive pin (5), which is connected to the cock lever, moves backwards. The pin, with its portion indicated by the reference numeral (12), presses on a form (9), which is used to release the piston (6) on the lock sheet (1). It lifts the sheet to allow the passage of the piston (6). The cock lever is continued to be pulled and thus the rifle becomes cocked. The buckshot is placed in the barrel mouth and the cock lever is closed. The buckshot drive pin (5) connected thereto also moves forward. When the buckshot drive pin leaves the lock sheet (1), it turns upwards by means of the sheet lock spring (2), to attain the lock position. When the trigger is pulled, the pressing location (13) of the lock sheet on the piston (6), which moves with the help of the spring inside, hits the position indicated by the reference numeral (11) on the lock sheet (1) to lift above the sheet for a moment. Having passed the lock sheet (1), the sheet turns downwards again, owing to the spring (2) on the same, and reaches the back side of the piston. When the piston (6) completes its movement, the location (14) at which the piston hits the valve pin presses on the end (15) of the valve pin (7) that contacts the piston, thus the valve is enabled to open and consequently the air is allowed to exit, and the buckshot is enabled to leave the barrel to complete the shot.
Once the shot is completed, as seen in Figure 2, the lock sheet (1) enables the piston (6) to stop in a way to press on the location (13) where the
lock sheet presses on the piston; hence the piston is prevented from coming back to hit the valve pin (7) due to the pressure inside the tube, and consequently the unnecessary air release is avoided. Also, the circumstance is eliminated in which the piston (6) is activated to hit the valve pin (7) in case the rifle is dropped down or hit during when no shot is being performed.
This system has eliminated the complaints of the users, increased the shot performance and enabled a higher number of shots. The pressure inside the tube is prevented from unnecessarily reducing in cases when there is no shot being made.
