AIR- GUN.

Patented sept. 1, 190s.

Application filed. April 12, 1907. Serial No. 367,838.

` a citizen of the UnitedStates of America, re-

' erence being larged longitudinal section t of the gun, illustrating the construction and siding at Detroit, lin the county of Wayne.

and State of Michigan, have invented certain new and useful 'Improvements in Air-Guns, of which the following. is 'a specification, refhad therein to the accompanying drawings.

The` invention relates to an Aair, gun pro-I `Avided with the usual plunger and actuating spring therefor, and consists in the construction of a firearm of this ty e wherein the compression of the spring an theshifting of the plungerA are eiiected at dierent eriods, instead of simultaneously ashereto ore, resulting in a'material decrease in the ower required to cock the un, and v.provi ing a iirearm that can be easily operated.

The invention further consists inthe peculiar arrangement andcombin'ation of the gun parts, and urtherin certain details oi construction as will behereinafter set forth.

lIn the drawings,-Figure `1 lis a vertical central?. section through an air un embodying -my invention, partly n Ae evation, the

parts beingshown in the 'posi-tion' Jfor shooting;' `.'2.is a similar view, showing thev gunin't e rocess of cockingl; yFig 3 is an enrough a portion arrangement of the barrel;-

4 is a cross section through the barrel, showing the same m' the loading position', and Fig-.5 is a detached perspective view of the reciprocatingI member for compressing the spring, and connections with the stock.

The .reference-letter K ofthe v"gun,terminating at its forward end in a hollow frame B, slotted in its lower portion, as atC.

D is a -casingppivoted to the frame B of the its stock Eftlie connection being such as to" provide a breakdown construction similar to a Vbreech-loading gun, andFrep'r`esents`"the gunbarrel secured to the casing in a manner to be hereinafter described.` Within the casing D is an air compression cylinder G, in vlhicha plunger I-I of any suitable type wor s.

H is a plunger rod, terminating at its free A :indicates the' stock tion.

l endin a hookllz, and I is'the actuating spring for the lunger, preierablyoi the coil type and enciicling the rod as indicated.

J represents the usual 'projectile-starting rod made hollow and provided with an inlet K'for the admission of the air, the ree end oi purpose to be hereinafter described. The

,gitudmally throughthe plug section for a means employed for compressing the spring -and shifting the plunger visA a reci rocating member P, the member being ma e hollow, and the parallel walls .P and P2 being in proximity to one another so as to iorm a guide- VWagto receive the rod H".

designates theusual trigger held in its retaining position by a spring R, the trigger` being pivoted to the reciprocating member and carried with it during its travel to and k.iro in the casing'.

As the means Jfor reciprocating the memb'er P, a link S is preferabl employed eX- tending through a s ot T in t ie reciprocating member, and having a pivotal connection with the latter, and being preferably connected at its opposite end to the frame B of the stock, the end portion U of the lever eX-- 4tending',within the opening C of the frame, as

plainly indicated. y

In the o eration of cooking the gun, the stock isl bro en down, as indicated in Fi 2, causing the reciprocating member encirc ing the plunger rod to bear against and compress the spring, theoperation ofcompressing being continued luntil the'liook uponfthe pluiif gerl rod engagesy the trigger..v Upon closing the breech of the un, thereciprocatin lmember is retracted, (Irawing with it the p unger, thus shifting the latter` into its shooting posi- The missile is then inserted within the gun barrel, ashereinafter set forth, and the gun is in readiness for use.

Itgvill be obvious from the construction' described that'ai'iy form of operating means sov ' position, slightly within the barrel Hush with l5 creased leverage that the gun stock in the breaking-down operation produces.l

The barrel F'referred'to is connected to the casing D in alinement with the air compression chamber, and is shiftable longitudi- 10 nally of the casing, and the connections are' Vof such a character that the barrel may be rocked or shifted out of alinement with the casing into a loading position to receive the projectile.- The rear'end of the barrel V is slightly reduced, and adapted to extend a short distance within the forward end of the casin while a pivot-pin W secured to the barre extends within the opening O in the plug section of the casing, and ashort distance therebeyond,`termi natin in a head-X. A spiral spring Y is interpose between the head and the plug section, and serves toA hold the barrel 'normally in alinement with the compression chamber.

To load the gun, t e barrel is adjusted axially of the casing at sufficient distance tov clear the casing end, and then rocked or rof tated sidewise into. the position shown in Fig. 4 to permit of the insertion of the projectile.

InV addition to the pivot-pin W described serving as the main connection between the barrel and the casing, I preferably proportion the parts s`o that the proj ectile-starting rod J will extend, when the plunger is in .the firing the casing end, as plainly shown in Fig. 1, the projectin portion of the rod J constituting additiona securing means for holding the barrel in its operative position.

From the foregoing description it will be readily seen that the work required in cocking the gun is divided, a part being performed during the breaking-down of the stock, and the balance `in restoring the gun to the shooting position,4 and thus the power necessarily cockin is reduced to a minimum.

Whi e I have shown the preferred mechanism for accom lishing this result, I do not wish to be limited thereto, as my invention contemplates broadly the shifting of the plunger and the compression of the plunger spring at different intervals during the o heretofore with the attendant disadvantages What I claim as my invention is,'- y 1 In an air g-un, the combination with.a
