United States. Patentlo 3,153,874 HINGED BARREL FIREARM WITH TRIGGER SAFETY MEANS Rex Raymond Merrill, 1853 8th Ave., N., Fort Dodge, Iowa Filed Aug. 1, 1962, Ser. No. 214,043 6 Claims. (Cl. 42-41) This invention relates to hand guns and more particularly to a single shot target pistol having a plurality of operational and safety features.
Single shot pistols are old and well known in the art and have evolved into a variety of configurations. However, all such pistols, especially single shot target pistols, suffer from the problem of being too complex.
Another drawback to pistols of this class is that they are generally difilcult to load and hard to cock.
Still another drawback to previous one-shot pistols of this class is that they generally have no provision for wear compensation and thus Will shoot loose in a very short time.
Still another drawback to previous one-shot pistols is that they have little or no safety provisions and, especially in the so-called free pistol category, are prone to accidentally discharge from a slight jar or from even a change in the weather and are thus undesirably dangerous. As is well known in the art, single-shot target pistol shooting has been discouraged in this country for this reason.
Therefore, one of the principal objects of this invention is to provide a pistol that is extremely simple in construction.
Another object of this invention is to provide a single shot pistol that is easy to load and unload.
A still further object of my invention is to provide a pistol of this class that is inherently easy to cock even when a fast hammer spring action is utilized.
A still further object of my invention is to provide a one-shot target pistol that makes provision for wearcompensation and thus will shoot tight for a very long period of time. i
A still further object of this invention is to provide a pistol having a unique direct safety provision whereby the pistol may be gripped in the usual manner and still be on safety until such time as it is actually on target and ready to be fired.
Still further objects of my invention are to provide a single-shot target pistol that is economical in manufacture, durable in use, and refined in appearance.
These and other objects will be apparent to those skilled in the art. I
My invention consists in the construction, arrangements, and combination, of the various parts of the device, whereby the objects contemplated are attained as hereinafter more fully set forth, specifically pointed out in my claims, and illustrated in the accompanying drawings, in which:
FIG. 1 is a side view of my pistol in cocked condition and with sections cut away to more fully illustrate it construction; I i
FIG. 2 is an exploded view of the parts that make up the auxiliary safety means; 1
FIG. 3 is a side view of my pistol in fired conditions, and with sections cut away; and
FIG. 4 is a side view of my pistol in opened position and with the left side plate removed to more fully illustrate the locations of the various parts.
In these drawings I have used. the numeral to generally designate the frame of my pistol which encloses the moving parts and includes the usual trigger guard 12, grip or butt-stock 14, and the enclosed rear area 16 of the gun commonly referred to in the art as the receiver or receiver area. The barrel 18 is vertically hingedly secured to the fore-end of the frame 10- by the downwardly projecting a 3,153 ,8 74 Patented Oct. 27, 1964 "ice,
hinge means 280. The rear surface 22 of the barrel is adapted to fit flush against the front surface 24 of the receiver 16. The top rear area portion of the barrel 18 is flat and is beveled to provide a depressed shoulder 26. A sliding bolt 28 is suitably longitudinally slidably grooved onto the horizontal top surface 30 of the receiver 16. The forward bottom surface 32 of the sliding bolt 28 is fiat and adapted to slide over and contact the beveled shoulder surface 26 f the barrel 18 and thus detachably secure the barrel in closed position. The sliding bolt 28 is yieldingly urged toward its forward position by means of the spring 34. The top forward edge 36 of the sliding bolt 28 is steeply beveled forwardly and downwardly so that it will automatically be pushed back by the bottom rear edge of the barrel 18 as the same is snapped shut. The firing pin 38 is operatively secured in its proper position within the receiver 16 by means of a suitable slidable arm and hammer means 40'and is yieldingly held toward its forward position by the coil spring 42 positioned between the receiver and hammer, as shown in FIG. 4. The pin 44 extends from the member 40 through the rear of the receiver and when the pistol is cocked it protrudes therefrom as shown in FIG. 1, to disclose to the user that the weapon is cocked. If desired, the hammer portion of the arm 40 may be a separate end of standard structure. The arm bar 40 extends forwardly over the pin 45 and under the roller pin 43, as shown in FIG. 4. When the arm 40 is pushed rearwardly the hammer spring 42 is compressed. This is accomplished by v the pistol being opened or broken. A downwardly extending lug 48 on the bottom of the barrel hinge portion 20 engages the forward end of the arm bar'40 and pushes the arm and hammer assembly rearwardly as shown in FIG. 4. It will be seen that even light downward pressure on the forward end of the barrel 18,- due to the favorable leverage involved, will easily compress even a very heavy or fast hammer spring 42. When the hammer arm 40 has been pushed rearwardly to its firing position, it is releasably held in check by the searnotch 52 in the forward bottom area of the arm 40 and which is operatively associated with and engaged by the usual trigger projection 54 of the trigger mechanism 56, as shown in FIG. 4. The trigger mechanism 56 may be of any suitable type, such asthe standard mechanical lever variety or the new electric powered type, or the like. The pistol carries the usual cross-bolt pin trigger safety,
. which may be the pin 45. Therefore the pin 45. may be longitudinally slidable, with respect to its longitudinal axis, to perform two purposes, i;e., as a safety means and as a supporting means for the hammer arm 40. Most important is my auxiliarypsafety. The auxiliary safety comprises a knurled exposed spur or plunger means 62 that operatively follows the contour of the thumbrest 64 yieldingly held upwardly by the spring 68. In its upward positionthe bar 66 positively locks the trigger mechanism in such a manner that the hammer arm 40 cannot be released. The spring 68 is, ofcourse, suitably secured and located within the grip as shown in FIG. 1. The spring 68 should be-of sufficient strength thatthe safety bar 66 will not be accidentally released until the shooter consciously depresses and holds the spur 62 down with his thumb, such. as when the gun is actually being aimed at the target and "the shooter is completely ready to fire. Thus it will be seen. that even when the pistol is in a hair-trigger, free pistol condition it is still safe from accidental discharge up to and including the time. when it is actually safely aimed at the target; at which time, of course, the spur 60 is despressed. The loeking of the trigger by the auxiliary. safety means may be accomplished in several different ways. In the drawings, I show a slidable rod 70 in the grip having its forward end engaging the back of the trigger 56. This rod is yieldingly held in a forward sliding position by the spring 71. On the rod 70 is a cam 72 having a cam face on its rear side that extends downwardly and forwardly and which engages a cam 73 on the bar tab 62. The face of the cam 73 also extends forwardly and downwardly. Therefore, when the bar tab 62 is depressed, the cam 73 will be lowered and will permit the rod 70 to slide rearwardly. When the bar tab 62 is in an elevated position, the cam 73 will be in an elevated position and engaging the cam 72, and preventing therefore the rear movement of the rod 70 and trigger 56. A rear sight 74 is mounted on top of the sliding bolt 28. The numeral 75 designates the front sight.
Some changes may be made in the construction and arrangement of my firearm without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.
