HIGH-POWER AIR-RIFLE.

This invention relates to ordnance appa-A ratus and more particularly to that class known as air guns, or rifles.

The main object of this invention is to produce an air-rifle which will be of high power and sufficiently powerful to be used for general sporting purposes, without requiring the use of gun powder or other explosives to give the bullets used the necessary velocity.

Another obj ect of this invention is to I have the riie constructed, so that it may be manipulated with ease and at the same time be provided with means for adjusting parts of the rifle, whereby its sensitiveness of action may be varied to suit the .conditions arising or the person using it.

A further object is to provide a high power riie which will be comparatively` noiseless and smokeless.

A still further object is to have the parts of the rilie easily accessible for inspection, repair and other purposes.

come apparent as it is more fully set forth.

The rifle referred to inthis application consists in general of a barrel arranged to receive the bullet and a casing properly attached to the barrel and provided with the rlhe working `general parts of the device. part-s consist of a movable chamber having a reduced opening arranged to aline with` the base of the barrel so that the blast of airi forced through the chamber by a plunger` provided therein, will force the bullet from the rilie in the manner desired. A suitablel `V illustrate an embodiment of this invention,

on a slightly enlarged scale. Fig. 3, is a longitudinal section though a. preferred form of bullet, to be used in this rie. Fig. 4: is a detail in perspective of a traveling air-chamber used in the rifle. Fig. 5, is a detail section showing the working parts in loading position, and the relative positions of the power arms, and air chamber to permit the bullet to be placed in the bore of the rifle, the trigger mechanism is not shown as it is similar to that shown in Fig. 2. Fig. 6, is a detail section, showing the bullet and working parts in shooting or cocked position. Fig. 7 is a detail section similar to Fig. 6, but of slightly modified construction. Fig. 8 is a detail of a safety device used in the rifle. Fig. 9 is a transverse section of the rifle on the line 9 9, of Fig. 2.

Similar reference characters refer to similar parts throughout the drawings.

In the construction shown in the drawings, l represents the stock or shoulder portion of the rifle and may be of any conventional design, and 2, is the trigger frame or protector, and is suitably attached to the rifle. The casing containing the main working parts of t-he rifle is designated by the reference numeral 3, and the barrel by 4. The casing 3 is in general, cylindrical, eX- cept at the portion 5, adjacent to the stock, where it is `arranged for the trigger mechal nism, and other parts working in connection Other objects :of this invention will be` therewith. The casing adjacent to the barrel A, is provided with a recess .6, for the bullet, which is slightly larger than the latte-r and the bore 7 of the barrel, in order to permit it to be easily placed therein, and a suitable opening 8 is provided in the casing close to the recess, so that the bullet can be easily placed in the riiie.

An air chamber 9, is provided in the casing and is arranged to slide easily in it. Its front portion l0, is restricted. interiorly to a conical shape, so that the air blast will be more suit-ably directed to the recess 6, when the gun is fired. A plunger 11, having a stem 12 is Vdisposed in the air chamber 9, and closely ts the saine, so that there will be but a slight leakage of air, when it is forced into the chamber 9. A strong coiled spring 13, is positioned on the stein 12, and connected to it and the stock of the gun, so that the plunger will `be actuated by it, when released from the catches 14, by the trigger v yIUS and are provided with hooked ends 17, which engage on lugs 18, provided on t-he stem referred to. Portions 19, of the catches are extended toward the adjusting screws 20, of' the trigger mechanism, so as to be actuated thereby, and springs 21, are provided for the purpose of keeping the catches suitably positioned for their work. The trigger proper is indicated at 22, and is attached to a body piece 23, which is pivotally held to the portion 5, of the casing and restricted in its downward movement by a pin 24. Fastened to the portion 10, of the air chamber is a lug or projection 25, to which a lever 26, has one of its ends pivoted and which in turn has its other end pivotally connected to a draw bar 27, which is pivotally connected to the portion 5 of the casing as is clearly shown in the drawings. The draw bar 27, and lever 26, afford a powerful means of returning the power spring to its cocked position, and for moving the other parts connected therewith. A handle 28 is provided on the draw bar 27 so that the latter may be easily manipulated, and a suitable catch 29 is provided for keeping it positioned horizontally when it is moved adjacent to the barrel and casing.

Referring vto Fig. 3, which shows a detail of a preferred form of bullet, 30 indicates the bullet proper, and 31, flanges on its rear portions adapted to engage in the rifiing curves in the barrel should same be pro vided. The flanges 31, are provided on the front portion of the bullet for a similar purpose.

In Fig. 7, the plunger is provided with a casing 32, instead of a stem, and which slides over casing 34a, which contains the power spring for actuating the plunger. The casing 32 is provided with slots 36, which slip on the guides 35, which are on the casing 34, in this modication. The lugs 18, are similar to those described for the previous modifications and for the same purpose. The casing 341, serves for keeping the power spring 13, properly positioned in the casing and also protect it from injury.

In operating the gun the operator first pulls down on the handle 28, and gets the worklng parts in the position shown in Fig. 5, then insert the bullet in the recess 6, at the same time the lugs 18, are caught on the catches 14, and the spring 13, is held under tension within the casing 34, until the trigger mechanism releases it. After the bullet 1s placed 1n position, the drawbar, its handle and the lever 26, are connected with it, and returned to their horizontal positions as shown 1n Figs. 6 and 7 This action places the air chamber in position so that the plunger will compress the air in it, and send the latter against the bullet in the recess 6, when the trigger isV pulled and the spring 13,

understood that the rifle may be supplied with the usual attachments provided for the purpose of assisting in aiming, etc., without referring to such in detail. Y

The attachment 37, is a device for preventing the movement of the catches, or sears, as they are often called and it consists in general of a lever pivoted in the casing and provided with a lug 38,-which comes in contact with the project-ion 19, on the catch or sear. One end 39, of the attachment is knurled so that it may be easily moved, and held so as to prevent the trigger mechanism for setting the gun off until desired. 40 is a slot provided in the casing 3, in order to permit the part 25, to reciprocate therein, in the desired manner..

Obviously while only two modications of this device are shown in the drawings, it is not desired to limit this application for patent to that particular construction or in any other way otherwisev than limited by the prior art as many modifications of-'this invention may be made without departing from the principles thereof and coming within the scope of the appended claims.
