<p>To simplify the structure and assembly of a stuffing device for putties contained in plunger cartridges, of the type adopting the shape of a pistol having a breech end (1), a semi-tubular receptacle (2) for the putty cartridge having a stop (3) for the said cartridge and a lever (4) including a piston (4a) for driving the plunger of the cartridge, which is axially displaceable by means of a trigger (6) bearing an actuating bolt (9) and a lock (11), which can operatively be coupled to a denting (5) provided on the side surface of the said actuator lever (4), there have been provided by-pass notches (12 and 13) provided at the side walls of the breech end (1) for the resting and positioning of a lock (11) in the form of a metal strip, which notches adopt the configuration of a circular sector having small radial prolongations (12b, 13a) in the form of recesses, at least one of which by-pass notches (12 and 13) is provided with a portion (12a) in the form of a vertical radial recess. The trigger (6) has a stop (6a) for the lower portion (9b) of the bolt (9) so that the upper portion (9a) thereof in the shape of a pawl will necessarily occupy a position with respect to the trigger (6) which ensures the correct operative positioning resting on the actuator lever (4). <IMAGE></p> |
