Patented May 3, 1932 ANTHONY SKINlJEL, OF WILDWOOD VILLAS, NEW JERSEY AIR RIFLE Application filed February 18, 1931. Serial No. 516,771.

This invention relates to an air rifle and has for its object to provide, in a manner as hereinafter set forth, a rifle of such class whereby the projectile to be discharged there- '6' from is projected by compressed a1r supplied from a source remote from and permanently communicating with the rifle.

A further. object of the invention is to provide, in a manner as hereinafter set forth,

an air rifle including a compressed air receiving chamber normally closed to a pressure relieving chamber and in communication with a compressed air source remote from the rifle, and a trigger operated means forestablishingcommunication between the chambers to provide for the discharge of the projectile by compressed air.

Further objects of the invention are to provide, inamanner as hereinafter set forth, an

air rifle which is simple in its construction and n arrangement, strong, durable, compact, thoroughly eificient when used, conveniently discharged and comparatively inexpensive to manufacture. a

With the foregoing and other objects in view, the invention consists of the novel construct-ion, combination and arran ement of parts as hereinafter more speci cally described, and illustrated in the accompanying 90 drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views Figure 1 is a side elevation of an air rifle and itscompressed air supply attachment in accordance with thisinvention.

Figure 2 is a fragmentary view in longi- -tudinal section.

Figure 3 is a disassembled view of the combined closure'and coupling disc for the air chamber and compressed air conducting line and illustrating the latter as detached from the closure.

Figure 4 is a fragmentary View in longitudinal section of a modified form of air rifle.

Figure 5is a fragmentary view partly in longitudinal section and upon a reduced scale of another modified form of airrifle.

Referring to Figures 1, 2, 3 and 4: of the drawings, 1 indicates the stock and 2 the body portion of the rifle. The rear end of the body portio1r2 is fixedly secured to the forward end of the stock 1, and the latter is disposed at a downward inclination with respect to body portion 2. i

The body portion2 includes a barrel part 3 of less length than body portion 2 and the bore of part 3 is indicated at 4. i

The body portion 2 intermediate its ends and in its upper part is formed with a pres sure release chamber 5' which permanently communicates with the inner end of the bore 4. The bottom 6 of'chamber 5 has a compressed air intake 7. That part of the wall of chamber 5 which opposes the inner end of the bore 4is formed with an opening 8. j

The body portion 2 rearwardly of the chamber 5 is formed with a pull bar chamber 9 having its rear end closed by the forward end ofstock 1. The body portion 2 is formed below part 3, chamber 5 and chamber 9 with an opening which extends from the rear end to the forward end of body portion 2. The rear end of such openin is closed by the forward end of stock 1. Xrranged within such opening rearwardly of the chamber 5 and below the chamber 9is'a partition 10 whichin connection with a closure disc 11 for the forward end of such openingprovides a compressed air receiving chamber 12. The wall of the lengthwise extending opening in body portion 2 andat the forward end thereof is threaded as at 12. The closure or disc 11 has its edge threaded for engagement with the threads 12 whereby the element 11 is detachably secured in position. The element 11 provides what may be termed a combined closure for the air chamber '12 and a coupling means for a compressed air conducting pipe 13 which leads from a compressed air storage tank 14. The element llis formed with an axial opening 15 havin'ga threaded wall with which engages the threaded upper end of an angle-shaped member 16 forming a part of the lineg13 and the major portion'of such line is flexible.

compressed air for the chamber 30 is supplied by a compressed air conducting line The bottom wall of the chamber 9 is slotted as at 17 The bottom wall of the lengthwise extending opening rearwardly of the partition 10 is slotted as at 18. The slot 17 is arranged over slot 18 and extending through said slots and into chamber 9 is a trigger 19 which is pivoted to the body portion 2 as at 20. The pivot isarranged below the upper end of trigger 19. Pivoted to the upper end of trigger 19, as at 21 is a forwardly extending pull bar 22 which projects through thef opening 8 and into the chamber 5. The forward end of pull bar 22 has pivotallycon' nected therewith a depending link 23 which extends through the opening 7 and is pivotally connected at its lower end to a controlling valve 24 for the. Opening 7. The valve 24 isarranged below the bottom 6 of chamber 5 and includes a stem 25'which passes through a guide member 26 arranged in the compressed air receivingchamber 12'.

The'projectile is indicated at 27 and which is mounted against a seat 28 formed at the inner end of the bore 4.

The form shown in Figure 4 is constructed in. the same manner as that shown in Figure 2, with this exception that the element 11 is removed and a valve-controlled partition member 29 is arranged within the lengthwise extending opening in body portion 2 and coacts with the partitionj10i to provide a compressed air receiving chamber 30 of materially less. length than the chamber 12. The

31 which leads from the tank 14 and is'con nected to the bottom. of body portion'2 and opens into chamber 30 rearwardly of. partition 29. The valve controlled partition 29 can also be employed when the element 11 couples the line 13 of body part 2 and when so employed the conducting line 31 is disconnected from body part 2 and the opening to receive said conducting line 31 is plugged. The port for the passage of air through the valve controlled partition29 is indicated at 32-and such port is closed when the conducting line 31 is employed but when element 11 couples -line 13 in position, the air pressure will: shift the valve part of the partition 29 to open port 22.

In theform shown in Figure 5 the body part is indicated at 33 and includes an extension 34 providing a continuation of the barrel portion 34. The lower portion 35 of bodypart 33 provides the compressed air receiving chamber 36 having an integral forward end. The line 37 for conducting com- H pressed air from tank 14 opens into the bottom of chamber 36.

1 Otherwise than that as stated theforms shown in Figures 4 and 5 will be the same as the form shown in Figure2.

7 If desired the trig 3 with a controlling spring to assist in restorer 19 may be provided ing it to normal position, but the pressure of air acting on valve 24 when the trigger is released will cause the latter to be moved to normal position.

When the lower portion of the trigger is moved rearwardly the push or pull bar 22 will be carried forwardly due to the upper end of the trigger swinging forwardly on its pivot. The forward movement of the push, pull or operating bar. will cause the link 23 to lower carrying thevalve. 24. therewith and opening the chamber 5 to chamber 12. The passage of the compressed air to chamber 5 will cause the projectile 27 to be discharged from the rifle, as chamber 5 is closed other than the point of communication with the inner end of bore 4. When the trigger is released the pressure ofair in chamber 12 will act on valve24 and shift it to close the bottom of chamber 5. i lVhat claim is 1. An airrifle comprisinga body portion having a barrel port provided with a bore, a pressure relieving chamber at the. rear of said port and permanently opening into the: pa bore, a compressed air receiving chamber below said other chamber and bore, a pull bar chamber at the rear of thepressure relieving chamber, a compressed air supply line opening into said receiving chamber, a norma1lyi'95 closed valve forcontrolling communication between said chambers, and shiftable means carried by said body portion and extending ,through the pull bar chamber and into the pressure relieving chamber'for shifting said'ict valve to establish communication between said pressure relieving and air receiving chambers toprovide for the discharge of a projectile mounted in said bore, said means including a pull bar.

2. An air rifle comprising a body portion having a barrel port provided with a bore, a pressure relieving chamber at the rear of said port and permanently opening into the bore, a compressed air receiving chamber bra-2.110 low said other chamber and bore, a compressed air supply line opening into said receiving chamber, a normally closed valve for controlling communication between said chambers, a link depending into said pressure relieving chamber and connected to said it forwardly to move said valve to open po- .sition for establishing communication between said chambers to provide-for the discharge of a-projectile mounted in said bore, and a guide within the air receiving chamber for said valve. 5

3. In an air rifle, a body portion formed with a chamber disposed longitudinally thereof, a pressure relieving chamber at its forward end of said other chamber and having an apertured bottom, a barrel part having its bore opening at the rear into said pressure relieving chamber, a compressed air receiving chamber arranged below said relieving chamber and bore and opening into said pressure relieving chamber, and superposed spaced slots rearwardly of said relieving and receiving chambers, a valve normally closing the receiving chamber to the relievhereto.
