Abstract
Toothed rotor feeder or conveyor device for automatic belt feeding weapon, especially for automatic weapon in which the unlocking of the stock is caused by a means other than recoil of the weapon, said conveyor device being arranged so that it is actuated by a motor device that provides motor impulses that are produced with each shot fired, for example and advantageously by the weapon itself at the moment of at least one part, hereinafter called the active part, of its recoil in relation to its support and the device for guiding the feeding belt integral with said support, the band being of course displaced by the rotor in a complete step for each shot fired, and said conveyor device comprising between said motor device and its rotor a transmission system comprising its a first rotating element dragged in rotation with each shot due to the recoil of the weapon in one area angle equal to or slightly greater than ** (see formula) ** and a second rotating element consisting of the toothed rotor that has n teeth and is coaxial with said first rotating element, between whose rotating elements an angular clearance corresponding to only a fraction of a full step of the second element, this play tending to be maintained by a prestressed elastic system that works in torsion and such that if, during the duration of a given motor impulse, the second element does not rotate a sufficient angle under the thrust transmitted by said elastic system, the latter is requested in torsion until, the clearance having been eliminated, its first element comes to drag the second in rotation imperatively by a stop, characterized by the fact that said elastic system is made up of a set of two torsion bars one of which is housed coaxially inside the other, these bars being rigidly attached to one another in a side of said assembly by its extremities that are in front of this side, this same assembly being arranged coaxially with the rotor shaft, internally with respect to said shaft, with the two active extremities of the two bars, that is, the opposite ones to those that are attached to each other, respectively fixed to the mentioned first and second elements, while the end of the set that is opposite to that in which the active ends of the bars are located rotates freely in the end facing the rotor shaft .
