SPRING AIR-GUN.

SPECIFICATION forming part of Letters Patent No. 446,711, dated February 17, 1891.

Application filed June 9, 1890. Serial No. 354,831. (No model.)

To all whom, it may concern:

Be it known that I, HIRAM II. PASSAGE, a citizen of the United States, residing at Plymouth, in the county of Vayne and State of Michigan, have invented certain new and useful Improvements in Spring Air Guns, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to new and useful improvements in spring air-guns; and the invention relates to the peculiar construction of the spring-compressing mechanism, and, further, to the peculiar construction, arrangement, and combination of the various parts, all as more fully hereinafter described. 7

In the accompanying drawings, Figure 1 is a side elevation of my improved gun. Fig. 2 is a vertical central longitudinal section thereof, and Fig. is a vertical crosssection on line {I} A is the stock.

13 is the false barrel, in which is secured the true barrel 0 by means of plugs D at the ends.

The projectile is loaded by dropping it into the muzzle, and itis held in the tapering seat E at the inner end thereof.

F is the air-eompressing piston secured upon the forward end of the piston rod G.

The rod G is centrally secured in the guide block I I, which bears against the forward end of the spring I, the rear end of which bears against the stationary plug K, which is suitably apertured to form a'guide-bearing for the piston-rod, which has the notch L formed 011 its under side and the inclined bearin g M at its rear end.

N is a stationary bearing in the rearof the false barrel, having the forward inclined face 0. This bearing I preferably make as the head of a screw, the body P of which passes through the barrel and through the stock and engages into the plate Q on the under side of the stock. In order to put this serewin position and adjust it vertically, I cut away the rear part of the upper side of the barrel B above this screw and secure thereon the breech-plate R, which forms a means for securing the rear end of the barrel to the stock, and upon its forward end is formed the hind sight S.

S is the trigger, consisting, preferably, of a bent wire pivoted at S, the upper end there- 'of being about in line with the bearing N,

while the lower end extends through the lower side of the stock and forms the finger-piece of the trigger.

Journaled in the plate Q is the spring-conipressing lever T, which has the rearwardlyextended arm T, forming the triggenguard, and the forwardly-extending arm T extends into a suitable slot formed in the fore-arm of the stock. This arm 1" of the lever is connected with the plug H by means of the link U, which at its forward end slidingly engages with the downwardly-projeeting arm U upon the plug II and has the adjusting-nut U at its forward end.

The parts being'thus constructed, they are adapted to operate as follows: To load the gun, the operator takes hold of the arm T of the lever, turns it upon its pivot, thereby with drawing the arm T- of the lever, and through the medium of the link U and the arm T co1npresses the spring. As the block H is :moved backward by this action, the rod G is correspondingly moved, and the incline M upon the rear en d thereof strikes the incline 0 upon the bearing N, which causes the rod to ride upon its upper edge until the notch L passes over the bearing, when it engages therewith and locks the rod in its adjusted position with the spring compressed. The lever T may now be returned to its normal position, (shown in Fig. 1,) the link U sliding through its bearing in the arm U. The operator dropsashot in the barrel, which is seated, as before described, at the lower end thereof. By pullingupon the trigger the rod G is lifted from its engagement with the bar N and the springis allowed to act, compressing the air and discharging the projectile.

I provide the bearing N with the slot V to enable me to more readily secure it in position.

hat I claim as my invention is-- 1. In a spring air-gun, the combination, with the barrel and the spring-actuated piston and its red, of a detent in said rod and bearing with which said detent engages and the trigger for disengaging said detent, substantially as described.

2. In a spring air-gun, the combination, with the barrel, the spring-actuated piston, and its'rod, of the block ll, secured centrally of said rod, the spring I, the stationary block K,

forming a guide for said rod, the detent onsaid rod, the stationary bearing N, and the trigger, substantially as described.

In a spring air-gun, the combination, with the spring-actuated piston and its rod,of the inclined bearing M, the detent L, the bearing N, having the inclined face 0, and the trigger, substantially as described.

4. In a spring air-gun, the combination, with the barrel of a piston and its rod having a beveled end and a notch in its under side, of a movable block rigid on said rod, having an extension on its under side, alever on the under side of the stock connected to said extension by a link, a stationary block having a central opening for the passage of the rod, a spring surrounding the rodand interposed be.- tween the stationary and movable blocks, a catch in the lower part of the barrel for engaging with thenotch in the rod and holding the spring in its compressed state, and means for disengaging said rod,substantially as dein presence oftwo witnesses, this 31st day of May, 1890.
