Definitions

  • the present invention relates to an improved apparatus for injecting putty and the like, more particularly for injecting this type of pastes contained in plunger-injector cartridges of the type comprising a receptacle for the putty cartridge and an actuator piston for driving the plunger of the said cartridge, which actuator piston is operated by its rod through a ratchet device operatively coupled to an actuating trigger.
  • This type of apparatus adopting the shape of a pistol and essentially comprised of a receptacle portion for the putty cartridge having a tubular arrangement and a front stop for the distal end of the cartridge, a handle portion in the shape of a breech, and a piston movable in an axial direction to the said receptacle portion for driving the plunger of the cartridge by means of a piston rod or piston lever partly dented on its lateral surface, which is operatively coupled to a trigger-actuated ratchet mechanism and a locking mechanism which prevents the rod or lever of the said actuator piston from returning, has been known since at least 1967.
  • the driving pawl is mounted on the trigger so as to turn freely about a pin, so that during assembly thereof it can rock on the said pin preventing it from remaining in a position opposable to the lever of the apparatus, wherefore the operativeness thereof would be prevented.
  • the assembly by means of the riveting of the locking mechanism of the lever is not desirable due to the high cost of the said riveting operation as well as to the impossibility of replacing the rivet in case of malfunctioning thereof without the appropriate riveting tools.
  • the object of the invention is to proportion an apparatus of the type initially described whereby the aforesaid assembly disadvantages are overcome.
  • the locking device of the driving lever of the apparatus is comprised of a simple metal strip resting on by-pass notches corresponingly made in the lateral walls of the breech end portion of the apparatus.
  • the notches are provided with a resting and positioning zone for the strip in the form of a circular sector and at least one of the notches is provided with a straight vertical recess, the length of which is at least equal to the length of the said strip.
  • the said strip can be mounted in an operative position by inserting it through the said straight recess.
  • the actuating trigger is provided with a stop to prevent the driving ratchet pawl or latch from rocking, so that its operative positioning with respect to the driving lever of the apparatus may be ensured during the assembly operation.
  • the putty injecting apparatus or machine adopts the general configuration of a pistol having a handle or breech end portion 1 and a semi-tubular receptacle 2 for the coupling of the injector cartridge with an anterior stop 3 for the distal end of the cartridge, forming a solid whole.
  • an actuator lever 4 which has a piston 4a for activating the plunger of the injector cartridge, not represented, so that the said actuator lever 4 can move in an axial direction to the receptacle 2 for driving the said plunger of the putty cartridge.
  • the actuator lever 4 is cylindrical in shape, half its side surface, at the most, includes a denting 5 and it is mounted on the handle or breech end portion 1 so as to turn freely around the studs on which it is mounted, so that it can face actuating elements or it can be uncoupled thereform by turning its back end 4b, as will be explained in detail later on.
  • breech end 1 is provided, for activating the dented lever 4, with a trigger 6 pivoting around a pin 7 which has a stop 8 opposable to the lower portion of said breech end 1 and a driving bolt 9 rocking on a pivot 10, with a pawl 9a for coupling to the denting 5 of the lever 4, So that when trigger 6 is activated, the said pawl 9a will drive lever 4 forwards, provided that the denting 5 thereof faces same; additionally positioned ahead of the bolt 9 is a lock 11 in the shape of a strip which, coupled between the side walls of breech end 1, prevents the lever 4 from returning, provided that its upper portion faces the denting 5 of the said lever 4, and permits movement thereof when the said lever 4 is driven forwards by the actuation of the trigger 6 and also the return of the said lever 4 when same is in a turned position, its denting 5 not being coupled to the lock 11 by turning its rear end 4b.
  • the side walls of the handle or breech end portion 1 of the apparatus are respectively provided with by-pass notches 12 and 13 on which the lock 11 rests, so that it can be mounted in the operative position, that is to say resting on the side surface of the lever 4 and being maintained at rest on the said notches.
  • the notch 12 is arranged in the form of a circular sector of approximately 30-45°, including a first straight portion 12a in the shape of a recess extending vertically upwards in a radial direction in a length at least equal to the length of the strip of the lock 11, and a second straight portion 12b, also in the shape of a recess, extending a short distance backwards in a radial direction.
  • the by-pass notch 13, in turn, made in the other side wall of the breech end 1 adopts the shape of a circular sector having the same extension as notch 12 but merely having a small portion 13a in the shape of a recess which extends radially backwards.
  • the lock 11 is comprised of a metal strip having two end bends 16 and 18 which rest, respectively, on the actuator lever 4 and the side notches 12 and 13, and it is further provided with lateral lugs 17 for resting on the said notches 12 and 13.
  • the said locking strip 11 can be assembled in an operative position, than is, its end 16 resting on the actuator lever 4, being maintained at rest by its lugs 17 on the side walls of the breeech end 1 in the notches 12 and 13 and with its end bend 18 fitting into the recesses 12b and 13b thereof.
  • positioning of the said locking strip 11 is extremely simple, since it merely has to be inserted laterally through the recess portion 12a of the notch 12.
  • the oscillating bolt 9 has an upper portion 9a in the shape of a pawl and a lower portion 9b having a U-section.
  • the trigger 6, in turn, has a notch with a stop 6a for the lower portion 9b of the bolt 9, so that the said bolt 9, once it incorporates its repositioning spring 19, occupies a fixed position with respect to trigger 6, provided that the repositioning force of the said spring 14 is not overcome.
  • the correct positioning of the pawl 9a of the bolt 9 is ensured when the trigger 6 is mounted between the side walls of the apparatus on its hinge pin 7.
  • figures 5 and 6 illustrate that the front part of the trigger 6 is provided with a recess 6b including a brace 6c for the coupling of a spring 15 for repositioning the trigger 6.
