Application filed February 7. 1905. Serial No. 244.664-

Be it lmownthut l, DAvin F. Fermi, residing at Plymouth, inethe county of Wayne and I: ate of Michigan, afc'itizcn of the United States, have invented certain new and use ful improvements in Magazine Air-Guns, of which the following is sspeciiicetion, referones being bad therein to the accompanying drswin s. 1 v

The invention relates to air guns of the magazine type and consists in certain feetures of construction, as hereinsiter set I forth.

In the drawings, Figure l is a longitudinal section through a portion of the barrel. Fig. 2 is a perspective View of the shooting barrel and members forming the piston abutment detached. Fig. 3 is a perspective View of the members shown in Fig. 2 assembled. Fig. {l is a cross section on line a::n through zine; Fig. 5 is an enlarged cross section through the shooting barrel.

The general construction of the gun may be of any desired type and comprises a false barrel, forming the air connression c lindcr and magazine, a shooting arrel wit iinthe false barrel and a sprin actuated piston for compressing the air. n addition to these parts, there is a pistonebutment between the magazine and cylinder for the piston and the delivery oi shot fromthe ma azine into the shooting barrel is controlled by a. member operated by the piston, these elements having all been present in previous construc tions.

The present invention relates perticularly to the constructionof the abutment for the piston and, further, in the combination therewith of the shooting barrel, the arrangement being such that said shooting barrel and abutment may be inserted in the rear endoi the false barrel.

In mrticular, A is the rearportion of the false arrvl, in which'is the iston B. C is a forward.extension of the is so barrel, which is of lesser diameter and within which is arranged the shooting barrel 1). The sections A and C are joined to each other, referably by telosco )ing their adjacent cm s and arranging aj )ushing E between the same, said parts being then brazed or otherwise secured to, each other.

The piston abutment F is attached to thedered engagement with the end of the false barrel C. Thus, when this cap is in position,

the abutment F will be held in place against the annular shoulder a.

Ashes been stated, the mags-zine tor the shot isiormed by the chambcrwithin the barrel C surrounding the shooting barrel D. The latter is provided with an aperture b at its rear end, through which the shot may be succcssiycly admitted to the barrel. This aperture is closed by a tubular gate H, which is attached to the piston and projects forward therefrom, telescoping within the barrel D. When the piston is in contact with the abutment F, the member H is in position to close the aperture b, but when the piston is retracted and its actuating spring compressed, the member H is withdrawn, so as to permit a shot to enter through the aperturc time the barrel D, as shown in Fig. 1.

To guide the shot into registration with the aperture 6, the forward portion of the abutment F is refersbly slotted, the slot being of just su. icient width, to permit the entrance of one row of shot therein. To avoid the necessity of drilling the abutment to form this slot and also to choapen the cost of constructing the abutment, 1 preferably form the latter in the following manner c are circular disks which are 0 a size to lit within the barrel A and are centrally a ortured at e to fit about the shooting barre D. f are smaller disks fitting within the barrel C and also centrally apertured at g tofit about the shooting barrel. The disks f are further provided with slots h, which extend'from the central aperture 9 to the periphery. The abutment is formed from a plurality of each of these disks and the disks are assembled in relation to each other, as shown in Figs. 1

struction being as described, the abutment F and barrel 1) may be inserted in the rear end of the barrel A and moved forward until the disks 0 abut against the shoulder a and the disks f fit within. the barrel C. The piston B may then be inserted and in normal position bears against the abutment F, while the tubular gate llrxtends forward within the barrel 1).

To load the magazine the cap G is removed and the shot is filled in to the annular space between the barrels D and C, after which the cap (I is engaged with the threaded end of the barrel D and closes the magazine.

In operation, whenever the piston is retracted, a shot is permitted to drop from the slot it through the aperture 7) into the barrel D and thus the gun is always loaded when the spring is under compression.

By forming the piston abutment F of the disks 0 and f, the cost of construction is considerably reduced. This is for the reason that disks may be rapidly and inexpensively formed by stamping and quickly assembled and rigidly secured to each other as has been described. abutment were made from a solid piece of metal; there would be a necessity for slotting and boring it, which would increase the cost of construction.

In Figs. 1 and 5 is shown another feature of the construction, particularly designed to hold the shot in the shooting barrel from displacement before shooting. Ileretofore difliculty has been experienced with magazine guns of this type/occasioned by the rolling of the shot forward before shooting. This will allow another shot to enter the shooting barrel, or to partially enter through the aperture b, with the result that when the gun is fired, the tube II will strike against the partially inserted shot, chipping off a piece thereof. In repeated operations, these pieces will accumulate in the breech of the barrel, so as to eventually clog it, and necessitate taking the gun apart to clean the barrel. I have avoided this difficulty by the construction shown, in which I is a spring detent secured to the barrel D and entering through a slot '11, in a position just forward of the aperture 6. This detent is sufficiently yielding to ermit the shot to pass when the gun is firer but forms sufficient resistance. to prevent the shot from moving forward in the barrel by its own weight. To further insure the retention of the shot in position until the gun is fired, a recess is formed in the lower side of the barrel, directly opposite the aperture b, so as to form a seat for the shot, which will prevent its moving forward. With the devices just described, the shot entering the shooting barrel through the aperture 1) is held in position directly beneath said aperture, so as to completelylbaigthe entrance of other shot or the projection of If, in place of these disks, theany portion thereof into the path of the tube ll. Thus, the chipping of the shot is pre-' vented.

What I claim as my invention is 1. In an air gun, the combination with the false barrel having a shoulder therein, of a shooting barrel, a piston abutment fixedlysecured to the rear end of said shooting barrel and'adapted to be inserted therewith in the rear end of said false barrel and against the shoulder therein, and a cap adjustably mounted on the forward end of said shooting barrel and engaging the end" of the false barrel.

2. In an air gun, the combination with a false barrel comprising two sections of different diameters, secured to each other and forming an annular shoulder within the larger section of a true barrel, a piston abutment secured to the rear end of said true barrel and having a portion thereof fitting each section of said false barrel, and a cap having a threaded engagement with the forward end of said true barrel, closing the end of said false barrel.

3. In an air gun, the combination with a false barrel comprising two sections of different diameters, of a iston abutment therefor comprising a pluraiity of stamped, metallic disks of a size to it the said sections of the false barrel and rigidly secured to each other.

4. The combination with a false barrel and a truebarrel therein, of a piston abutment comprising a plurality of stamped disks having central apertures for fitting about the true barrel, said disks being integrally united to each other and to said true barrel and con stituting a rigid member extending between the false and true barrels.

5. In an air gun, the combination with a false barrel and a shooting barrel therein, of a piston abutment comprising the disks 0 and f, sleeved upon and rigidly secured to. said shooting barrel and to each other, the disk f being provided with registering slots and said shooting barrel with an aperture in registration with said slots, whereby the shot 1s guided through said slots and aperture into the shooting'barrel. I

6. In an air gun, a false barrel, a true bar- 115 rel positioned therein, and forming a magazine of the space therebetween, said true barrel being provided with a lateral opening at the breech thereof, a iston abutment comprising a plurality of mtegrally united 120 stamped disks fitting said false barrel and sleeved upon said. true barrel, one of said disks being provided with a slot in registration with the aperture on the true-barrel.

7. In' an air gun, a false barrel provided the passage therethrough of the true barrel,

said disk being integrally united with the true barrel and constituting a rigid member extending between the false and true barrels, and means for causing a binding action between the piston abutment and the shoulder in the false barrel; 8. In an air gun, the combination with a false barrel, comprising two sections of different diameters, ofa true barrel having a shot opening therein, and a piston abutment secured to the true barrel formed of a plurality of stamped metallic disks of a size to fit within the said sections of the false barrel, a portion of said disks having slots therein adapt- .ed to register with the shot opening in the 15 a shooting barrel.

end of thefalse barrel, and means for causing a bindin action betweenthe piston abutment and the shoulder in the false barrel.
