DESCRIPTION:
BRIEF SUMMARY
Prior miniature firearms of the same caliber are not shaped so as to constitute a scaled-down version of a standard firearm and they serve to shoot rockets and not to fire bullets.
The miniature firearm of the present invention fills these gaps employing miniature embodiments of two different standard handguns.
In a miniature firearm of this type, which should be capable of functioning, it is nevertheless not possible to scale down all the internal parts of the standard firearm, particularly those of the firing mechanism because the existing ammunition for 2 mm caliber cartridges are designed for rimfire and not for centerfire.
Two embodiments of a miniature firearm according to the invention are shown schematically and solely by way of example in the drawing, in which:
FIG. 1 is a front view of a first embodiment in the "off" position, in which certain portions have been broken away;
FIG. 2 is the same view but at the moment when the shot is about to be fired;
FIG. 3 is a view of a portion of the rear face of this first embodiment, partially in section;
FIG. 4 is an end view of a portion of FIG. 3;
FIG. 5 is a plan view of the firearm of FIG. 3, with a portion in section;
FIG. 6 is a front view of a second embodiment, in its natural size;
FIG. 7 is a scaled-up view of the parts of the firing mechanism in the position they occupy at the instant when the shot is about to be fired; and
FIG. 8 is a plan view of one of the parts of FIG. 7.
The miniature firearm according to the first embodiment (FIGS. 1 to 5) is a scaled-down version of a Colt-type revolver. It has been designed in the form of a piece of jewelry which can, for example, be worn as a pendant. Barrel 1, frame 2, and butt 3 are made of gold, the latter being studded with brilliants 4. In its natural size, this firearm is 4 to 5 cm long. Its caliber is 2 mm.
Cylinder 5 of this revolver has chambers 6 for six cartridges 7 (FIGS. 2 to 4). These cartridges are of the rimfire type. By striking radially on the stem 8 (FIG. 2), which juts out of cartridges 7, the charge is ignited and the bullet 9 fired. Cylinder 5 rotates about an axis 10 which is integral with a mount 11 rotating on a pivot 12 (FIG. 3) between the firing position shown by the solid line in FIG. 4 and the loading position indicated by the dash-dotted line in the same figure. A lug 13, pushed into a hole in frame 2 by a spring 14, normally locks mount 11 into the firing position of cylinder 5.
A lever 15, which turns on a pivot at 16 (FIG. 5) on frame 2 allows lug 13 to retract in order to free mount 11, removing it from frame 2 so as to bring cylinder 5 into the loading position. Extractor 17 (FIG. 3) of the empty cartridge case is simulated in simple fashion. If they do not drop by themselves from chambers 6 of cylinder 5, these cartridge cases can be pushed out by means of a pin, for example.
The firing mechanism of the revolver shown is essentially composed of a sear 18 and a hammer 19. The latter rotates about a dowel pin 20 against the action of one end of a spring 21 which is wound about a lug 22 of butt 3. It carries a pawl 23 which turns on a pivot at 24 and is subjected to the action of a thrust spring 25. Compared with the standard revolver, whose hammer carries a firing pin which strikes the wafer located in the center of the bottom of the cartridge case, the site of the pivoting point 20 of hammer 19 has been modified so that hammer end 26, which serves as a firing pin, falls vertically on stem 8 of cartridge 7 contained in upper chamber 6 of cylinder 5 starting from the position in FIG. 2. Like the hammer of the standard revolver, that of the revolver described herein has been constructed with a nose 27, which allows it to be operated manually in the position shown in FIG. 1. However, in the firing position, hammer 19 is not held mechanically.
In the miniature revolver, nose 28 of sear 18, which simulates the trigger of the standard revolver, would not be accessible in trigger guard 29 if the latter were integral with frame 2. In the revolver described herein, this portion
