Definitions

  • This invention relates to an improved automatic weapon loading mechanism, more particularly of the type of which a spring must be tensioned for the discharge of a blow.
  • this mechanism will be used on air rifles.
  • This mechanism has the disadvantage that the nut will have to continually make a back and forth movement, in order to return to its initial position after the load of the blow where the repositioning of the nut is an action which takes energy and time.
  • the present invention relates to a loading mechanism for weapons in which a double-turn loading system is applied which, if necessary after loading, can immediately perform a new loading action without having to perform a prior return action.
  • Such an improved weapon loading mechanism consists mainly of a piston actuated by a spring and an electric motor with reduction gear, characterized in that the spring is compressed by the piston where the recoil displacement which results in tension of the above spring is controlled by the cooperation of the piston with an endless traction device.
  • the traction device in a preferred embodiment consists of a circulating chain, controlled and supported by chain wheels.
  • This chain is preferably provided with two protruding shafts, at two opposite locations which, alternately, continuously resume the same start and stop positions in order to perform a loading operation or not.
  • An additional advantage of the present invention also consists in that a hook-shaped element which can be pulled by a shaft which is preferably provided on an endless chain is connected to the piston, in such a way that when the said spring is located practically at the end of its tension stroke, (i.e. in its compressed position) the above-mentioned shaft is positioned exactly where it will make a circular circuit. Therefore, it follows that this tree, during the first 90 degrees of the circular path performed, will have a horizontal velocity component from the initial (0 degrees) to zero (90 degrees). This speed component can be calculated for each positioning by multiplying the initial horizontal speed component with the sine of the angle in which the tree is located. It is clear that the horizontal velocity component will have a sinusoidal progression.
  • Figure 1 shows a weapon 1, in this case an air rifle, in which the improved mechanism is indicated by part F2 and in which the energy for this charging mechanism is, for example, supplied by a battery 2 installed in the butt.
  • the motor 4 and the reduction gear 5 are shown diagrammatically, mounted in the housing 3.
  • the motor 4 produces a rotary movement transmitted to the reduction gear 5 by means of a shaft 6.
  • the reduction gear transmits the rotary movement through the shaft 7 provided with a bevel gear 8 which can cooperate with a second bevel gear 9 on which an accessory chain wheel 10 is provided.
  • the latter is connected to a similar chain wheel 11 via a chain 12, on which two protruding shafts 13-14 are provided in this case.
  • the toothed and chain wheels 9, 10 and 11 are mounted on bearing shafts which can rotate freely in the housing 3.
  • a piston 15 with control spring 16 provided which are installed in a chamber 17 around a rod.
  • a flexible forked element 18, for example made of spring steel, bent downwards and which has a fold like a hook 19 at its free end is suitably provided for the piston 15.
  • the element 18 extends, through a slot 20, into the chamber 21 where the control mechanism is located.
  • the toothed wheel 9 and the chain wheel 10 is located on a shaft 22 while the chain wheel 11 is located on the shaft 23.
  • the parts of the shaft 23 next to the chain 12, i.e. d. the parts of the shaft 23 which may be at a given moment under the arms of the element 18, are only constituted by a segment 24 whose scope will be explained below.
  • the operation of the loading mechanism according to the invention is very simple and as follows.
  • the loading mechanism In the rest position, the loading mechanism is in the position as shown in FIG. 2.
  • the motor 4 By controlling an electric switch not shown in the drawings, the motor 4 can be supplied with current.
  • the engine turns the chain wheel 10 will drive the chain, thanks to suitable transmission means 6 to 9, along arrow P.
  • the protruding shafts 13 will engage at a determined moment in the hook-shaped fold 19 of the element 18 and, consequently, training the latter.
  • the piston 15, to which the element 18 is fixed will also be driven and will compress the spring 16.
  • the shafts 13 will then continue to perform a rectilinear horizontal movement up to the chain wheel 11 and more particularly up to the position A. From point A, the shaft 13 will deviate from its initial rectilinear horizontal movement and start a circular movement from position A to position C. In this way the original horizontal movement component in position A, between positions A and C, will be partially converted into a vertical movement.
  • the chain 12 will drive the shafts 13 to a position, as shown in Figure 4, after which the hook 19 is released from the shafts 13 so that the element 18 returns to a position as shown in the figure 5, since the segments 24, more particularly their edges 25 also act on this element 18 in order to ensure its clearance with respect to the shafts 13 in this case. From this moment the motor 4 will stop turning.
  • This can be applied by installing a limit switch not shown in the drawings at a suitable location and requested either by the chain 12 or by the element 18.
  • the piston 15 can then be unlocked, for example, by an expansion mechanism, also not shown, which can be controlled from the trigger 22.
  • the shafts 13 are placed in the position of the shafts 14 in FIG. 2 and the shafts 14 have taken the starting position of the shafts 13 in order to be ready for a new loading. .
  • FIG 5 shows the loading position which, after an unloading command, will change to take the position as shown in Figure 2, with the difference that now, the shafts 13 and 14 have changed places.
  • a system which is especially applicable for air rifles is the embodiment described above. It is obvious that this improved loading mechanism can also be used on other kinds of weapons and for other purposes.
