REPEATING AIR-RIFLE.

Specification of Letters Patent.

Application illed November 10, 1918. Serial No. 800,108.

Patented Mar. 3, 1914.

To all whom t may concern Be it known that I, ARvInEoK, a subject of the King of Sweden, and resident of St.. Louis, Missouri, have invented certain new and useful Improvements in Repeating Air- Ritles, of which the following is a specification containing a full, clear, and exact description, reference belng had to the accom- -panyng drawings, formlng a part hereof.

My invention relates to improvements in repeating air rifles, and the primary object of my invention is to construct an air rifle comprising an air pum with a valved chamber 'for the storagev o air, and to arrange means for bodily moving said chamber forl the operation of one of said valves to release the stored air; and a further object of my invention is to construct an air rifle comprising a pump with a plurality of valved chambers'for the storage of air from said pump, 4and to arrange means whereby said chambers may be selectively broughtv to register with the barrel of the rifle and to arrange a trigger for moving said chambers for the release of the air in the selected chamber.

With the above purposes in view my invention consists in certain novel features of const-ruction and arrangement of parts as will be. hereinafter more fully described, pointed out in the claims'and illustrated by the accompanying drawings, in which- Figure 1 shows in elevation a rifle constructed according to my invention, a portion of t-he cylinder and barrel and a portion of ythe stock being removed; Fig. 2 is an enlarged transverse sectional elevation taken on the liucl 2-2 of Fig. 1; Fig. 3 is a transverse sectional elevation taken through the plurality of air chambers; and Fig. 4 is a longitudinal, sectional elevation taken on the v line 4-4 of Fig. 3, a portion of the cylinder and barrel beingshown.

Referring by numerals to the accompan ing drawings: 5 designates the stock, in t e forward upper margin of which there is a recess G and to the rear of and in a plane beneath said recess is a recess 7, and extended vertically through the stock at a point immediately to the rear of the recess 7 is a trigger opening 8.. Formed vertically through the stock at about the longitudinal center of the recess 6 is a vertical bore 9.

10 designates a plate shaped to seat 1n each of the recesses 6 and 7 and arranged to be removably secured to the stock by means of a bolt 11. which yis fixed to the plate and arranged to be extended through the open.- ing 0 in the stock and a knurled nut 12 arranged to be threaded to said bolt and engage the stock. Secured-to the plate 10 and projecting forwardly beyond the end of said plateis a cylinder 13, and carried by the cylinder is a barrel 14 which projects rearwardly beyond the end of the cylinder 13. Fixed to said barrel are the usual sight and bead. Arranged for o eration in the cylinder 13 is a piston 15, s own only by dotted lines in Fig. 1. 'Secured to the piston 15 is a rod 16, the end of which projects beyond the forward end of the cylinder and has secured thereto an operating knob 17. At the rear end of the cylinder there is a head 18 and secured to said head and preferably by threading is a `tubular shaft 19 which is in- :ternally'threaded at its free end.

20 designates a tubular sleeve arranged for rotation as well as longitudinal Inovements upon the tubular shaft 19. At its rearmost end the sleeve 20 is enlarged to receive the head of a tubular set screw 21 which serves to limit the rearward movement of the sleeve 2O relative to the tubular'.` shaft. Radiating from the sleeve 20 is a lplurality of webs 22 and connected withthe iouter ends of the webs is a cylinder 23 and at the ends of the cylinder 23 are the heads 24 and 25. lprovided a number of separate and distinct '-air chambers 26. In the head 25 there are formed ports 27 communicating with each chamber and .formed in the outer face of the head 25 is a plurality of radiating channels 28 leading from the sleeve 20 to nach port 27.

29 designates a cap plate for the head 25 which is -removably secured by means of screws 30. Formed in the head 24 in communication with each of the chambers 26 is a screw threadedopening arranged to receive a threaded sleeve 31, comprising a combined ball holder and tubular valve stem 32. Arranged to seat against the inner end of the threaded sleeve 31 in each of the chambers 26 there is a disk valve 33, and arranged to seat in each port 27 there is a ball 34.

35 designates an extensile coil spring located in each chamber and designed to normally hold a ball such as 34 and a valve such as 33 seated. Arranged to seat in the-rearmost endof the tubular set screw 21 is a `ball 36 which is normally held seated by an extensile coil spring 37. Carried by the plate 10 and preferably formed integral therewith It will thus be seen that there isis a pair of rearwardly extending perfo-v rated ears 38 in which is pivotally mounted a trigger 39.

entire cylinder forwardly which movement As shown 1n Fig. 2 the cap plate 29 is provided. with a plurality of notches 40 each of which is arranged on a median line of each air chamber 26. Carried by the plate 10 is a dog 4-ll which is spring actuated to normally engage vin said notches 40. By this means the valved, threaded tubular sleeve 31 in each cylinder is brought to registration with the barrel 14.

, It will thus be seen that when the piston 15 is operated by a manipulation -of the knob 17 the air from the cylinder 13 will be forced through the tubular shaft 19, will unseat the `ball 36, will pass through each of the channels 38 and through each of the ports 27 into the chambers 26, Where it will be stored and held by the valves 34 and 33. A ball to be discharged is then inserted into one of the combined ball holders and tubular valve stems 32and, by reason of the in.- ner taper of said ball holder', the ball is frictionally held. The cylinder 23 is then .rotated until the ball holder is brought to register with the barrel, the dog 41 maintaining such registration. Thetrigger is then manipulated which, in its movement, bears against the cap plate 29 and -moves lthe first firmly seats the end of the barrel 14 into the threaded tubular sleeve 31 until 'the end of the barrel engages the ball holder. A continued movement of the trigger ,causes further longitudinal movement of the ent-ire cylinder which means that the barrel moves the ball holder in a position to unseat the valve 33, thus-.releasing the air from. the chamber 26 and driving out the ball from the ball holder.

s It is obvious that all of the chambers are simultaneously filled ywith compressed' air and that, if it be desired to use the rifle as a repeating rifle, it is only'necessary to supply a ball toeach ball holder. v.

I claim:

1. An air rifle, comprising a barrel, avalved air chamber, and means for bodily moving the air chamber to effect a release of the air therein to discharge through said barrel.

2. An airrifle, comprising a barrel, a plurality of valved air chambers arranged to communicate one at a time with s/aid barrel, and means for effecting a release of the air stored in the chamber in communication with the barrel.

3. In an air rifle, an air compressing means, a revoluble unit comprising a plurality of air chambers, means for selectivelyvbringing any one of said chambers into communication with saidlbarrel, and means for releasing the air from said selected chamber to discharge through said barrel.

.4,'In an air riie, a piston, a cylinder, a tubular shaft supported by said cylinder, a unit comprising a number of. valved air chambers rotatably mounted on' said shaft, a ball holder in communication with each chamber, a barrel, means for selectively holding any one of said ball holders in parallelism with said barrel, and a trigger for bodily vmoving said unit to bring said ball holder to enga-ge with said'ba-rrel to effect a release of the air fromsaid selected chamber to discharge through said barrel.

In testimony whereof, I have signed my name to this specific-ation, in presence of two subscribing Witnesses.

, V ARVID non.
