Specification of Letters Patent.

Patent-ea May 1a, 191e.

T0 all 'whom t may concern.'

Be it known that I, CHARLES F. LErnvEn, a citizen of' the United States of America, residing at Plymouth, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Guns, of which the following is a speciication, reference being had therein to the accompanying drawings.

The invention relates to a gun of the type in which air is compressed to eject the projectile. One 0f the objects of the invention is to obtain a construction in which the tube containing the projectile is removably engageable with the barrel of the gun and forms a cylinder within which air is compressed for ejecting the projectile, Another object is to Obtain means for ejecting the tube and for safe-guarding the manipulator of the gun when the tube is removed and also means for positioning the tube within the barrel of the gun. A further object is to obtain a construction which is very similar in appearance to an army riie. Still further obj ects reside in the novel arrangements and combinations of parts as more fully hereinafter set forth.

In the drawings:

Figure l is a side elevation of the gun;

Fig. 2 is a longitudinal sectional View therethrough with the tube for containing the rojectile removed;

Fig. 3 is a similar View with the tube for containing the projectile in place within the barrel of the gun;

Fig. t is a traverse sectional View on the line lf-4; of Fig. 3;

Fig. 5 is a sectional view through the plunger.

A is the stock of fthe gun having the hand portion A', B the barrel, C the trigger, C the side plates on opposite sides: of the trigger and depending from the barrel, D the trigger guard, and E and E are, respectively, the rear and forward sights mounted upon the barrel. .For securing the barrelB to the stock A and its hand portion A the clip F is provided surrounding and `slidably engaginof the forward ends of the barrel and the hand portion and the screw D is provided threadedly engaging the strap C2 con necting the depending side plates. The screw also secures the forward end of the trigger uard D to the hand portion.

For t e purpose of further giving the gun the appearance of an army riie the strap Il" is secured to the clip F and to the rear end i cf the stock A and the locking bolt G having the laterally-extending handle Gr rigidly mounted upon mits rear end, is slidably mounted within thebarrel B.

The barrel B is pro-videdin'its upper portions with the elongated aperture H through which the tube I may be inserted into the barrel and with the elongated slot H having at its forward end a laterally-extending recess I-I2 which slot and recess `are slidably engaged b-y theguide J upon the-locking bolt G. The strap B for'reinforcing the barrel B is connected to rthe outer sides thereof and extends Iover the'slot I-I, suicient clearance being provided 'for the passage of the guide J along the slot. The locking bolt G is `hollow and has its forward end rigidly secured to the cylinder K which has an Outer diameter such that it slida-bly fits within the annulus K within the'barrel B and has an inner diameter equal to the inner diameter lof the tube I.

For positioning the tube within the barrel B, fthe cylinder K has the tapering forward end K2 which is adaptedto engage the outwardly flaring end I of the tube I. The barrel B is provided with the annulus -L located forward of the apertureH and having its rear end L tapering. The tube I has its forward end I2 of reduced diameterl which end slidably engages the tapering end L and is positioned thereby, the forward movement of the tube vbeing limited by the shoulder I8 contacting with the taperino' end L. The projectile M is made of yielzdable i tube I. This lplumger is rigidly connected.

to the rod N extending rearwardly within the locking bolt G, this `rod in turn being rigidly connected at its rear end to the transversely-extending and depending detent member O having the detent O. Connected to the lower end of the detent member O is the forwardly-extending rod P substantially parallel to the rod N. The rod P extends through the strap Q connecting the forward ends of the depending side plates C and,

has at its forward end the transverselyextending member' P. A coil spring Q is provided surrounding the rod P and abutting against the strap Q and the trans- 5 versely-extending member P. The hand .portion Aof the stock :forms the housing for inclosing the spring. The locking bolt Gr has the longitudinal slot Gz'in'its lower portion through which the detent member O Ipasses, the slot extending from 4the rear end ofthe locking bolttothe cylinder K. For en'gagi'n'gthedetent O the sear R is provided pivoted lat Rl upon the depending side flanges C ofthe'barrel iB. Thev spring S 'engaging a' recess inthe lstock A and also en-gaging .alrearprojection R2 upon the sear fyieldably :forces the same forward and upward l'tol-engage the detent O when the .llatter'fis -moved'backsuiieiently far. The l-triggei-Caalso'pivotedlaltfR is adapted to ydisengage the scar YR from "the detent O 4 lithereby ,permitting of the rapid forward movemei'it 'of the plunger vN through vthe stored power in thespring Q.

`Inlorderftofeject'the tube I, the ejector yrodS is providedpivoted at S2 upon the *barrelj'B-and' extending through the slot T in the lower portion ofi theV barrel. Between fthe outerend of the ejector rod S and the lower--side lof-thebarrel B is the coil spring T""which yiel-dably normally forces the opposite or inner end upward through the slot T--so'lgthat upon lremoving the cylinder K fromthe-r'ear end ofthe'tube I, the ejector lIjo d-'S isi-'free to force the tube out of enengagement with the barrel. The ejector `rd #also performs the -function of safe- ;guardingthe I manipulator ofl the gun when the v tube is removed, since the spring T 'yieldably normally holds the forwardend of 'the ejector rod S inthe path ofmovement lloft-he plunger so that the latter can not "-i'noveinto 'thegspaceleft vacant by the cartridge. In order to prevent the lateral dis- 45 @engagementof the ejector rod S from the rfpli'inger j N, kthe plunger is lmade cup-shaped 'v'vithlthe iforwardly-extending flanges U so that! ifthefejector rod S were moveddownward, itscontacting end would engage with the lower forwardiy-extending flanges of lthe plungerand -wouldjbe prevented from "moving ifarther.

lInoperation, assuming the parts to be in position, as shown in Fig. 3,the' gun is in f` condition lt'obe liredby vpulling the trigger yC peri-nits of .the forward movement ofthe `Qplunger N intoy thetube I und-er the storedp'ower-in the "spring Q. To eject v'thej-vtube'I the locking bolt G is drawn backward thereby Idrawing the tapering end K2 .ofthev cylinderK out of engagement with thefflared'fend I `of .theltube I and also the plunger N 'out' of the tube, thereby permit- "'ting'oftheupward movement of the inner 55 gend of tlieffe'jector rod 2S to force theit'ube out of the barrel. The plunger N is withdrawn by meansof the lower forward cud G3 of the locking bolt Gr contacting with the detent member O. Upon further backward movement of the locking bolt the detent O is engaged by the sear R and the spring Q is placed under greater compression.

A vtube with its projectile can now be placed into the barrel B by forcing the inner end of the ejector rod S downward and this tube is positioned by moving the locking bolt G forward with its guide J engaging the slot H when the cylinder K engages the tube I so that both the forward and rear lends of the tube are positioned. By rotating the locking bolt G to place the guide J in the laterally-extending recess H2 the tube is locked in position and the gun is in condition to be again fired.

When the tube I is not in place, the inner end of the ejector rod S is in the path of movement of the plunger N so that the latter can not move into the tube space when the gun is uncooked. Furthermore the ej ector rod S can not be forced out of engagement until the plunger N is moved backward due to the flanges U upon the plunger N. To assist in giving the gun the appearance of an army rifle, the tube I is made to look like a cartridge and is adapted to receive the projectile before insertion into the barrel of the gun.

From the above description it will be readily seen that a gun is provided which has the appearance of an army rifle and is safe t0 operate either when the tube is in or out of place. Furthermore, it is seen that the tube forms the cylinder for the compressed air and is positioned within the gun so that the plunger will easily engage the tube.

That I claim as my invention, is:

l. In a gun provided with a barrel, a tube simulating a cartridge, insertible into the barrel of the gun to form an element of the air compression chamber.
