6 Claims. (01. 12413) This invention relates to novel and useful improvements in guns.
An object of this invention is to forcibly emit a projectile from a gun barrel by an improved structure which includes the principle of operating a piston in a cylinder for urging the pellet from the barrel, the piston being operative in response to an electrical impulse caused by a solenoid in operation or other suitable equivalent electrically operative element.
Another object of this invention is to teach various structural adaptations of the air operated ejection of projectiles whereby motive force in the form of compressed air in movement is derived through an electrical impulse caused to be set in motion from a suitable source of current, such as a battery or other, through the use of an improved trigger mechanism.
Ancillary objects and features of novelty will become apparent to those skilled in the art, in following the description of the preferred forms of the invention, illustrated in the accompanying drawings, wherein:
Figure 1 is an elevational fragmentary view of a part of a gun, showing particularly the cliptype arrangement for charging the gun with projectiles; v
Figure 2 is a sectional View taken on the line 22 of Figure 4 and in the direction of the arrows;

Figure 6 is a transverse sectional View taken on the line 6--6 of Figure 4 and in the direction of the arrows;
Figure '7 is a longitudinal sectional view showing a second form of the invention differing from the first primarily in the choice of current supply and location of solenoids; and W Figure 8 is a longitudinal sectional view of another modification, showing a bank of solenoids together with a slightly modified trigger structure, as a differentiating feature over the illustration of Figure '7.
Many air rifles and air pistols are commonly known and used. My invention deals with an improved gun of this type, adapted particularly for target use, although the gun may be used wherever found practicable or desirable.
There are three illustrated forms of the device disclosed herein. The first form includes various details of Figures 1-6, inclusive. Many of the conventional elements of guns are used, such as the stock llLtrigger guard l2, and barrel 14. A plate I6 is disposed beneath the trigger guard and partially held in place by the screws Ill and 20 which hold the trigger guard fixed in place to the body of the gun. A recess 22 is formed in the stock ill for accommodation of various operative elements.
Disposed in this recess is a conventional solenoid 24 which is held in place by any suitable means as the bracket 26. The solenoid core 28 is reciprocable in the solenoids field coil and has a lever 30 pivoted thereto by a lost motion connection 32. A pin 34 is passed through the lever 30 and attaches it within the recess 22 for pivotal movement at a point substantially intermediate its ends. The end of the lever 30 opposite that having the lost motion connection 32 has a pivot pin 36 fixed thereto which is disposed in an opening 40 formed in a piston 42. The lever or rod 3!! is adapted to be operated by the solenoid so that the piston 42 is reciprocated in the cylinde M.
The cylinder 44 is disposed at the rear end of the barrel M and is in comunication therewith. The rear end of the cylinder has a removable plug 46 therein for assembly purposes. Conventional piston rings 48 are used in the expected manner. i a
A hollow pusher as the sleeve 50 is disposed in the end of the barrel l4 and has a lip 52 at the inner end thereof which is disposeddn the cylinder 44. This hollow pusher or sleeve is of resilient material, preferably rubber of sufficient rigidity, to serve one of its functions, which is to push the projectiles forward slightly in the barrel. I
An opening 54 is formed in the platelfi and has a trigger 56 passed therethrough. A part of the trigger is disposed in the recess 58 which is formed in the stock at the front of and spaced from the recess 22. An operator arm 60 is pivoted on a pin 6| intermediate its ends within the recess 58 and has one end pivoted to the trigger 56 by a lost motion connection 62, and the other end pivoted to the sleeve 5|] by means of a pivot pin 64. Accordingly upon operation of the trigger which is slidably disposed in a bearing block 66 mounted on the plate l6 within the recess 58, the arm 60 is operated, thereby slidingly operating the sleeve 50.
Means resiliently opposing the operation of the arm 60 is disposed in the recess 58. The preferable means consists of a spring of the flat or coil 68 variety having one end disposed in a boss 10 which is carried by the stock and the other and disposed in an identical boss 12 which is secured to the arm 60.
A lateral opening 16 is provided slightly in front of the trigger 56 for accommodation of the clip 18 having a spring therein pressing the breech of the barrel 2I8.
3 against the elevator 82, which in turn supports the projectiles 84. Spring-loaded balls 86 are carried by the gun body for operation in small recesses supplied in the edges of the clip (Figure 1) in order to fix it in place firmly and retain it in the proper position.
There are three openings provided in the barrel and cylinder structure. The front opening 90 communicates with the constantly spring biased projectiles 84 so that the uppermost projectile may be urged into the bore of the barrel I4. The second opening 92 is for passage of the arm 60 whereby it may be reciprocated by the trigger 56 and spring 68 mechanism for proper operation. The final opening 96 is a passage opening for the rod or lever 30.
In Figure 4, the device is shown preparatory for shooting. When the trigger 56 is pulled in the proper manner, the horizontal part I00 which is slidable in the bearing block 66 is urged rearwardly so that the contact I02 which is carried thereby bridges the two contacts (Figure 5) I04 and I06, respectively. The contact I02, although carried by the trigger 56, is insulated from the remainder thereof by the electrically insulating material I08 which is interposed therein.
By bridging the two contacts I04 and I06, one side IIO of the electrical circuit is completed so that current obtained from the plug I I2 enters the solenoid 24, therebyreciprocating the arm 30 and urging the piston 42 forward forcibly. In so urging the arm 30, the spring H5 is compressed, thereby opposing the operation thereof and acting as a return for the piston.
7 However, while the trigger was being operated in the expected manner, the resilient sleeve 50, which has a bore, is urged forward an amount so as to push the top projectile forwardly of the opening 90 so that compression would not be lost.
When the trigger 56, is released after having fired single projectile, the springs 68 and H5, respectively, reacting on the arm 60 and the rod 30 opposing the operations of each, cause the position of elements, as disclosed in Figure 4, to occur. Hence, another pellet or projectile is disposed in the gun barrel preparatory for operation which will be caused by simply operating the trigger again.
Referring now to Figure '7, a second form of the invention is shown. Here, the stock 200 is provided with a recess 202 for accommodation of a battery 204. r
A trigger 206 which is identical to the trigger 56 has a part 208 thereof reciprocable in a bear: ing block 2I0, disposed in the recess 212 of the gun body proper. r
A clip having pellets 2I4 therein, which is indicated at 2| 6 and which is identical to the clip disclosed in Figure 3 is provided for feeding The said barrel 2I8 is disposed on the stock and has a cylinder 220 at V the rear part thereof communicating therewith. A removable plug 222 is provided in the end of the cylinder 22!] so that the solenoid 224 may be disposed therein. An opening 226 is provided in the cylinder 220 so that the wires 2'28 and 230, respectively, may be passed therethrough. The wire 228 connects directly with the battery 204, while the wire 230 terminates in a contact 232 which is at the end of the bearing block 2I0. A second contact 234 is also provided in theend of the bearing block 2 I0 which has awire 238 leading therefrom and terminating in the battery 204. Accordingly, when the contact 240 which is carried by the part 208 of the trigger 206 comes into bridging relationship with the contacts 232 and 234, the circuit of the solenoid 224 is completed. Since the contact 240 is carried by but insulated from the trigger 206, no current will be lost through the trigger. simply an electrically insulating section 242 carried by the trigger.
A piston 244 is disposed in the cylinder 240 and may .be provided with conventional piston rings. A rod 246 extends from the piston and is disposed within the solenoid 224, serving as the core therefor. Springs 246 are disposed in the inner end of the cylinder, reacting on the barrel and also reacting on the piston to serve as a limiting means for the said piston.
In operation, projectiles 2I4 are fed as de-' scribed in connection with the first form of the invention. That is, when the spring 250 which reacts within the bosses 254 and 252, carried by the arm 256 and the stock, respectively, the resilient sleeve or hollow hammer 258 is pivotally operated rearwardl so that the spring in the clip urges the top projectile into the bore of the barrel. When the trigger 206 is pulled for firing; the two contacts 232 and 234, respectively, are bridged thereby, energizing the solenoids 222. Hence, the piston 244 is urged outwardly against the spring opposition in order to forcibly emit a charge of air through'the bore of the barrel 2I8, thereby carrying the projectiles which are disposed therein with it. In the return operation of the arm 256 by the spring 250, the hollow sleeve 258 moves rearwardly to allow a pellet 2I4 to move upwardly, but when the arm is moved for operation a slight amount, the pellet 2 I 4 is moved forwardly slightly in the barrel prior to the bridging of the contacts 234 and 232.
Referring to Figure 8, another embodiment of the invention is disclosed. This embodiment diiferentiates primarily from the embodiment of Figure 7 in the duplication of the solenoid 224. There is a second solenoid 300 disposed in tendem with the solenoid 224. This will, of course, indicate the lengthening of the cylinder 302 with respect to the cylinder 220. However, the remainder of the barrel and cylinder construction is identical with that disclosed in Figure 7, aside from the necessary lengthening or shortening of parts as the rod 304. Y
The trigger 306 is slidable in the insulating bearing block 308 and there is a slightly different arrangement of constacts to be bridged. A first contact 3I0 is provided and then there is a second contact 3I2, together with a third 3I4. An insulating member 3I6 forms a part of the trigger and carries a contact 3I8. When the contact 3| 8 bridges the two contacts 3| 0 and 3I2, through appropriate wiring 320 and 322, the solenoid 300 is energized. Then, when the trigger is operated slightl further, the contacts 3I2 and 3M are bridged, thereby operating the solenoid 224 through appropriate Wiring 320 and 324. Accordingly, the stroke of the piston in this embodiment is materially lengthened in order to insure greater compression.
