SPRING-GUN.

Specification of Letters Patent.

Patented Sept. 25, 1917.

Application filed April 7, 1916. Serial No. 89,604.

To all whom it may concern Be it known that I, CHARLES F. Lnrnvnn, a citizen of the United States of America, residing at Plymouth, in the county of Wayne and State of Michigan, have 1nvented certain new and useful Improvements in Spring-Guns, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to guns of that type in which the projectile is directly propelled by a spring, and the invention comprises the novel construction as hereinafter set forth.

In the drawings:

Figure 1 is a longitudinal section through the gun before the tensioning of the spring;

Fig. 2 is a similar view showing the sprin under tension and about to be release and Fig. 3 is a transverse section showingthe manner of anchoring the projectile sprlng.

The specific construction shown is that of a istol, but it is obvious that it is equally applicable to other t es of gun. As shown, A is the frame an handle of the pistol,

referably formed of a sheet-metal stampmg, and B is a false barrel telescopically engaging said frame and having formed 1ntegral therewith a trigger section. Within the barrel B is the true. barrel D, which is mounted for movement therewith and with the trigger section C. E is a sprmg within the true barrel, which projects beyond the rearward end thereof and is anchored to the frame. As shown, said spring E is sleeved upon a ide-rod F which extends into the barrel and which is notched at its rear end at G to engage the complementary halves of the sheet-metal frame to be anchored thereto. This guide is also notched at H for anchoring engagement with the end of the spring E. I is a detent or sear mounted on the trigger section C and engaging the spring E near the forward end thereof, the arrangement being that when the trigger seetion .is pulled rearward to produce the telescopic movement of the barrel B the forward end of the spring E will be carried backward while the rear end remains stationary upon the frame A, so that the spring is placed under tension.

The projectile directly engages the forward end of the spring and is propelled by the recoil of said sprin upon the release of the detent or sear I. t is, however, necessary to maintain the projectile in contact with the spring until the latter is released and to this end I have provided a second detent or retainer J, which is released simultaneously with the release of the sear I. As shown, the detents I and J are both formed upon a lever K pivoted at L and extending rearward in the space between the parallel sides of the trigger section. This lever is yieldably pressed upward to project the detents I and J into the barrel D by a sprin M engaging a pintle N on the lever abutting against the flange O of the trigger section. The rear end of the lever K is cammed at P and is adapted in the rearward movement of the telescopic barrel and trigger section to strike against a cross-pin Q, which at the completion of the rearward movement deflects the lever downward so as to release the detents I and J. This permits the spring E to recoil and to eject the projectile from the barrel.

I preferably provide the gun with a magazine for the shot or projectiles which is adapted to automatically feed the same successively into the firing barrel. As shown, this magazine is formed by a trough-shaped member R above the barrel D having an aperture S at its rear end opening into the barrel D and loading aperture T preferably slightly in advance of the aperture S. The aperture T is normally closed by the portion of the frame A with which the barrel D is telescoped, but when the trigger is drawn rearward this aperture T comes into registration with an aperture IT in the frame so as to permit of loading. Thus to load the un the operator draws back the trigger, fifis the trough R with the shot, and upon the forward movement of the trigger and false barrel the loading aperture is closed so as to prevent loss of the shot.

The spring E is employed solely for the propulsion of the projectile and as it is released by the sear when the trigger and false barrel are in rearward position it cannot operate to return these parts to normal position. I have therefore provided a second spring V which is preferably sleeved about the barrel D and spring E, its rear end bearing against the frame and its forward end bearing against an abutment W in the false barrel B. This spring will be placed under'compression by the rearward movement of the barrel B, and upon the release of the trigger will carry the same and the barrel B forward to normal position.

With my improved construction the bullet or rojectile being directly seated on the endof the propelling spring dispenses with the necessity of a piston and other cooperating parts which are usually employed. This not only simplifies and cheapens the construction but cuts out frictional loss and increases the force with which the projectile is propelled.

What I claim as my invention is 1'. In a spring gun the combination with a barrel, of a spring therein having its forward end forming a seat for the projectile, a detent or sear for engaging said spring adjacent to said seat, means for compressing the spring while engaged by said detent or scar, and means for releasing the sear.

8. In a gun, the combination with a telescopic barrel having a true or firing barrel in the forward section thereof, of a spring in said true barrel having its rear end projecting and anchored in the rear section of the telescopic barrel, a sear mounted on the forward section for engaging the forward end of said spring, and means for automatically disengaging said sear at the completion of the rearward telescopic movement.

4. In a gun, telescopically engaged, sections, at true barrel mounted on the forward section, a spring engaging said true barrel forming a seat for the projectile at its forward end, the rear end of said spring projecting from said barrel and anchored to the rear telescopic member, a sear mounted on the forward telescopic member engaging the forward end of said spring, a trigger for telescopically collapsing said sections to tension said spring, and means for tripping said sear at the completion of said telescopic collapsing movement.

5. In a gun, the combination with two telescopically-engaged members, one constituting the frame and handle and the other the barrel and trigger section, of a true barrel carried by said false barrel and trigger section, a spring engaging said true barrel forming at its forward end a seat for the projectile, its rear end projecting from said true barrel and anchored to said frame, a sear mounted on said false barrel and trigger section, and engaging the forward end of said spring, and means for tripping said sear upon the completion of the rearward movement of said trigger section to release said spring.
