Definitions

  • An operating mechanism for an explosion-operated device such as, for example, an animal-slaughtering device.
  • the control mechanism includes a breech body in which a ring pin is guided for longitudinal movement.
  • a swingi able hammer coacts with the ring pin to drive the latter when the hammer is released to the force of a driving spring.
  • the hammer itself is provided with a cocking tooth, and a catch tooth coacts with this cocking tooth to lcock the hammer until the catch tooth releases the cocking tooth.
  • This catch tooth forms part of a swingable operating lever which has an arm projecting laterally therefrom.
  • a spring assembly is located between this latter arm and the hammer and as a result of its compres- Sion between these components acts to maintain the catch tooth in ⁇ engagement with the cocking tooth until the lever is turned to compress the spring assembly to an extent sufcient to drive the hammer. At this time, the catch tooth automatically moves away from the cocking tooth.
  • the present invention relates to explosion-operated devices.
  • the present invention relates to tirearms similar to the type used in particular for driving an anesthetizing instrument into an animal for anesthetizing the" animal in connection with the slaughtering thereof.
  • the structure of the invention can be used with other types of explosion-operated devices such as any type of pistol or the like used to drive a projectile with the force of an explosion.
  • the simplest includes a ring pin drive longitudinally along the breech by a spring.
  • This pin terminates at its front end in a tip which extends into the cartridge chamber to engage the firing cap at the rear end of a cartridge therein.
  • the firing pin is provided with a nut which is formed with a recess in which a springactuated two-armed control lever is received, this lever being supported for swinging movement by the breech body.
  • the tiring pin Prior to firing, the tiring pin is displaced out of the breech and is releasably maintained in its cocked position by an arm of the operating lever which is received in the recess of the nut.
  • the second arm of the operating lever is depressed so as to bring about the release of the firing pin which is driven forward to strike against the tiring cap of the cartridge.
  • This known mechanism is extremely simple as well as reliable. However, it has no safety structure and is incapable of preventing accidental or unintentional firing.
  • a breech body supports a tiring pin for longitudinal movement and a hammer means coacts with the firing pin to drive the latter.
  • This hammer means is provided with a cocking tooth with which a catch tooth coacts.
  • the catch tooth forms part of a swingable operating lever which is supported for pivotal movement by a pin carried by the breech body, and this body also carries a pin which supports the hammer means for swinging movement.
  • the operating lever has an arm which denes with the hammer means a space in which a spring means is accommodated.
  • This spring means is compressed between this latter arm and the hammer means to resiliently and releasably maintain the catch tooth in engagement with the cocking tooth in such a way that during manual turning of the 'operating lever the spring means, which drives the hammer means, will be compressed until the catch tooth becomes displaced beyond the cocking tooth whereupon the compressed spring means expands to drive the hammer means into engagement with the tiring pin.
  • FIG. l is a partly schematic longitudinal sectional elevation fragmentarily illustrating an explosion-operated device which includes the structure of the invention
  • FIG. 2 is a top plan view of the structure of FIG. l;
  • FIG. 3 is a fragmentary longitudinal sectional elevation showing the structure of FIG. 1 in the position it takes just prior to release of the hammer means which is shown in PIG. 3 in the position it takes when it is almost fully cocked, and
  • FIG. 4 is an end view of the structure of FIG. l as seen in the direction of the arrow P and illustrating how the 'breech body, and the structure carried thereby, can be tilted to a position which will expose the chamber of the cartridge-carrier to enable a shell to be removed therefrom and a new cartridge to be inserted into the cartridge chamber.
  • the illustrated structure includes a breech body 1 extending rearwardly beyond and operatively connected with a cartridgecarrying body 3 which is formed with an axial bore 2 which forms the cartridge chamber.
  • the body 1 is itself formed with an axial bore in which a firing pin 4 is guided for axial movement, this pin being acted upon by a coil spring 5 which is coiled about the pin and situated in the bore of the -breech body 1 which also receives the firing pin.
  • the extent of axial movement of the ring pin 4 is limited by a cross pin 6 which is carried by the breech body and extends across a downwardly directed elongated recess 7 which is formed in the lower surface portion of the pin 4.
  • the breech body 1 is formed with a cutout or recess 8 having the stepped configuration apparent from FIGS. l and 3.
  • the body 1 carries a pivot pin 9 which extends across the recess 8, and this pin 9 serves to pivotably support the pivotable hammer means 10.
  • the hammer 10 is formed with a cocking tooth 11 while at its opposed forwardly directed surface, also at the region of the elevation of the pivot pin 9, the hammer is formed with grooves 12.
  • the hammer 10 is provided with a projection 13 adapted to engage the rearwardly directed surface 14 of the body 1 which defines part of the stepped recess 8, so that the surface 14 coacts with the projection 13 to act as a stop for limiting the extent of pivotal movement of the hammer 10.
  • the projection 13 will engage the surface 14 to limit the pivoting of the hammer 10.
  • a catch tooth 15 coacts with and engages the cocking tooth 11 of the hammer means 10.
  • This catch tooth 15 forms part of a pivotable operating lever 16 which is formed with an elongated slot 17 through which a second pivot pin 18 extends, this pin 18 also extending across the recess 8 and being xedly carried by the body 1.
  • This operating lever 16 is actually a two-armed lever having a rear arm 19 which carries the catch tooth 15 and a front arm 20 provided with an upwardly directed projection 21 which can be pressed downwardly lby the operator. At its lower side this front arm 20 has a downwardly directed tooth 22 received in an elongated depression 23 formed in the body 3 and in the body 1.
  • the lever 16 below the elongated slot 17 through which the pin 18 extends the lever 16 includes a downwardly directed arm 24 which extends into the recess 8 downwardly beyond the elongated horizontal portion of the body 1 which carries and interconnects the pivot pins 18 and 9.
  • This downwardly directed arm 24 is formed with an aperture 25 extending therethrough, as indicated in FIGS. 1 and 3.
  • a spring means is compressed between the arm 24 and the hammer means 10.
  • This spring means includes an elongated rod 26 one end of which is received in the aperture 25 and the opposite end of which is provided with projections in the form of ribs respectively received in the grooves 12 of the hammer 10.
  • the rod 26 has a head 27 provided with the transverse ribs which are received in the grooves 12, respectively.
  • the spring means includes a coil spring 28 coiled about the rod 26, engaging the forwardly directed shoulder, formed by the front end of the head 27 where it surrounds the rod 26, and pressing against the arm 24.
  • Other types of connections between the arm 24 and the hammer 10 can be provided such as telescopic connections, for example. However, the illustrated construction is preferred because of its simplicity and reliability in operation.
  • the body 1 is formed with a bore 48 extending up to the junction between the cartridge chamber and the front end of the bore in which the tiring pin is guided, so that gases can escape through this bore 48 in the event of an accidental ignition of the igniting cap situated approximately at the location of the front tip of the tiring pin.
  • the breech body 1 is formed at the region of its front end with an arcuate groove 29 receiving the rear ange 30 situated at the rear end of the body 3, the latter being formed just in front of the flange 30 with an arcuate groove which receives a front flange directed inwardly at the front end of the breech body 1.
  • the breech body 1 is capable of being tilted between the open position shown in FIG. 4, where the axis of the breech body is laterally displaced from the axispof the bore 2, and a closed position where the breech 1 and body 3 are coaxial.
  • the rearwardly directed surface of the outwardly directed flange situated at the end of the body 3 is formed with an arcuate groove 31 (FIG.
  • this groove receives a matching arcuate rib 32 projecting forwardly Ifrom the front end surface of the breech body 1, the rib 32 and groove 31 extending along a common circle so that it is possible to circumferentially displace the rib 32 in the groove 31 to tilt the breech between its open and closed positions.
  • the breech body is formed at the upper part of its front face with an arcuate groove 34 extending along a circle concentric with that along -which the rib 32 extends, and the body 3 carries a pin 33 which is received within the groove 34 so as to coact with the latter to limit the extent of tilting of the body 1.
  • an ejecting lever 35 which can be manipulated by the operator, in a manner forming no part of the present invention, to displace an ejector 36 rearwardly so as to eject an empty shell out of the cartridge chamber 2.
