Abstract
Pistol for slaughtering animals with captive projectile and hinged breech block, the breech block 13 being automatically locked to the breech 10 before the explosion by means of a balancing lever 37, inside the breech block, having a head 40 at one end for cocking the percussion pin 50 and a tooth 39 at the other end that fits onto a tooth 36 on the breech, the initial stroke made by the trigger 72 causing rotation of the lever 37 and hook-up onto the breech 10, continuance of the trigger's stroke causing said hook-up to be strengthened, releasing the percussion pin 50 for its forward movement.
Claims18
A pistol having means accomodating a captive projectile and a cartridge to be exploded, the pistol comprising:
- a hand grip (11) with an edge (73);
- an oblong body (70) hingably mounted and spring biased in said hand grip (11), said oblong body (70) having a trigger portion (72) projecting outward beyond said edge (73) and being arranged so that said oblong body (70) rotatably pivots when said trigger portion (72) is squeezed inward relative to said hand grip (11);
- a breech (10) formed to accomodate a cartridge (15) to be exploded in the pistol;
- a breech block (13) defining a trajectory path (56) to said breech (10) where said cartridge is to be accomodated, said breech block being hingably mounted to swing upwardly and forwardly to said breech (10);
- an internal balancing lever (37) pivotally mounted in said breech block (13) and having a projection (40) movable into said trajectory path (56);
- a percussion pin (50) spring biased in said breech block along said trajectory path (56) toward said breech (10) where said cartridge (15) is to be accomodated;
- spring means (44) for maintaining said projection (40) in said trajectory path (56);
- means for holding (53) said percussion pin (50) against said projection (40) when said percussion pin (50) is in a cocked position in which said projection (40) is in said trajectory path (56) and said percussion pin biases against said projection (40);
- means for rotatably pivoting said internal balancing lever (37) when said trigger portion (72) is squeezed inward relative to said hand grip (11) and including an arm (74) extending from said oblong body (70) and arranged to press against said internal balancing lever (37) when said trigger portion (72) is squeezed inward relative to said hand grip (11);
- and
- means for fittably locking said breech (10) and said breech block (13) together after squeezing said trigger portion (72) a predetermined amount and including two teeth (36, 39), one of said two teeth (36) being formed on said breech (10) and the other of said two teeth (39) being formed on said internal balancing lever (37), said two teeth being arranged relative to each other to fittably lock said two teeth in each other when said trigger portion (72) is squeezed causing said arm (74) to rotatably pivot said internal balancing lever (37) and therefore said other of said teeth (39) against and along said one of said teeth (36) of said breech (10), said trigger portion (70) being thereafter squeezable further inward to further rotatably pivot said internal balancing lever to cause a tighter grip between said two teeth (36, 39) and to cause release of said projection (40) from said holding means (53) and therefore from said percussion pin (50) so that said percussion pin (50) consequently biases sharply forward along said trajectory path and into contact with a cartridge accomodated by said breech (10) thereby causing the cartridge to explode.

A pistol for slaughtering animals, the pistol having means accomodating a captive projectile and a cartridge to be exploded, the pistol comprising:
- a hand grip (11) with an aperture (73);
- a percussion pin (50);
- holding means (53) fixed to said percussion pin (50);
- a breech (10) with a tooth (36) and formed to accomodate a cartridge to be exploded;
- a breech block (13) defining a trajectory path (56) to said breech (10) where said cartridge is to be accomodated, said breech block (13) being hingably mounted to swing upwardly and forwardly to said breech (10), said percussion pin (50) and said holding means (53) being arranged so as to be movable along said trajectory path;
- an internal balancing lever (37) with a back head (40), a front top portion with a tooth (39), a lower end portion with a convex ridge (41), said internal balancing lever being pivotally mounted to said breech block (13), said breech block (13) being formed so that said back head (40) is movable into said trajectory path;
- means for maintaining said back head (40) in said trajectory path of said percussion pin (50) and including a spring (44) biasing said back head into said trajectory path of said percussion pin (50), said breech block (13) being formed to be movable into a closed position in which said tooth (39) of said top front portion of said internal balancing lever (37) lies counterposed to and a short distance from said tooth (36) of said breech (10);
- and
- an oblong body (70) with a top portion and with a lower portion (72) constituting a trigger portion, said oblong body (70) having an arm (74) with a top edge (75) extending from said top portion of said oblong body (70), said trigger portion (72) projecting from said aperture (73) in said hand grip (11), said percussion pin (50) being movable into a cocked position when said holding means (53) grips said back head (40) of internal balancing lever (37), said oblong body (70) having an articulation (71) close to said arm (74) inside said hand grip (11) so that said oblong body (70) rotates about said articulation (71) when said trigger portion (72) is squeezed inward relative to said hand grip (11) thereby initiating a stroke, said trigger portion (72) being formed to move along a short section of said stroke in which said edge (75) of said arm (74) is thrust against said convex ridge (41) of said internal balancing lever (37) to cause rotation of said internal balancing lever (37) so that said tooth (39) of said internal balancing lever (37) fits onto said tooth (36) of said breech (10) to thereby lock said breech block (13) with said breech (10), said trigger portion (72) being thereafter further movable along said stroke to cause a further rotation of said internal balancing lever (37) which tightens a grip between said tooth (36) of said breech (10) and said tooth (39) of said internal balancing lever (37) and also releases said back head (40) from said holding means (53) and therefore said percussion pin (50) so that said percussion pin (50) consequently moves forward sharply to contact the cartridge (15) and cause the cartridge to explode.
