To all whom may c ano en.-

Be it known that 1, JOHN Hermon immune, a citizen of the United States, residing at New York, in the county of flew York and State of Her; York, liaveinveniede certain new and useful llniproveinent in Cartridges, of which the following is a full, clear, and exact description.

This invention consists of a cartridge for large and small firearms (automatic.orrapid lire) wherein the bulleU- that is to say, the

' projeetile--cerrics intend-all; or in permanent vention; showing also detached plug to the attachment he shell which orms the powderchaniher, the primer being applied to a plug" which has r. f ig'iblc connection with the shell and from which plug the shell and projectile segiarete upon the firing of the charge,

. provision made for ejecting the plug.

In th eccoin Hing; drawings, illustrating my invention, in t several figures of which like parts ere sinnlarly designate l, Figure l is an elevetion of one illustration of my in- 52 is a longitudina' sectitm eit. The hall, bu et, or projectile (a is made ini iell F) in which is the charge oer explosive o.

r is closed by means of of oowde of this poi c a plug (5, having about which the shell is fitted fric otherwisein such manner that the loge c and shoulder/"l .nally or oint between the two may be broken by the discharge or explosion of the powder charge.

i do noi hunt the invention to any perticir lar manner of forming the joint between the n I r 1 plug and she sliell so iongas such oint 18 suificic ntly s rong to withstand ordinary handling and may be broken upon; the ignition of the powder charge.

is the prii ier, of suitable construction.

will be understood that upon firing the cartridge the projec fie and the shell portion separate from the ping and pass out at the muzzle of the gun, While the plug remains in the breech and may be ejected in any suitable manner or any suitable means.

1 may employ aluminium in the construction of the cert-ridge; but i do not limit my invention to any particular material or metal.

Asthe, cz'irtridge starts through the bore of the charge The rear end the gun a part of the powders chm-go is carried with it, thereby filling the bore with gee until aches the muzzle. The cartridge conical in shape. and as it leaves its place in the chamber or breech and enters the bore proper it partly collapses until it fits the bore and rifiing' so perfectly that none of the gas can escape, and hence the maximum power of the powder charge may he utilized in the meterial increase of the velocity of the projectile. The projectile lem es the gun with the rifling perfectly impressed upon it and having a. rotary motion on its loiwitudinel axis.

.ln those guns which are gned to receive bottle-necked cartridges it may be necessary to use a thiinblc or bushing the chamber in order to adapt my conical cartridge for therewith.

it will be noted that the tapered shell will so collapse when entering the riliing of the gun-barrel as to form a. tight joint between said shell end barrel whereby all he gases created by explosion are kept at the rear of the proj cling bullet and that oi' the gas is permit-zed to precede the said projecting bullet, which is a desideratuin, inasmuch as inc confinement of the behind the bullet resuits in the economical use of powder, or, in other rds, by the use of a less amount oi powder greater amount or renge is obtained. it will be further noted that by forming an integral structure comprising :2 hollow powder-chamber and esolid end which forms the bullet proper the structure manifestly may be "produced at a low cost.

What 1 claim is- 1. A projectile comprising-a solid bullet end and a flexible shell integral therewith and enlarging from'seid bnllet cnd said shell beingv reducible by the rifiing when the projectile is fired.

2. A projectile comprising asolid bullet end carrying an elongated tapering shell,

we enlargement of the Boer icing farthest from said bullet end. and the well of said shell be- 9 mg of a material sull iciently pliable so that it is reduced in size when entering the rifiing'oi" the gun, andzi primer-coo y fitted into the mouth of shell..

3. Aprojectile comprising esolid bullet end, 100

a shell at the rear thereof and enlarging therefrom. said shell being flexible so that when the projectile is fired the former 'willbecome reduced in size and fit the rifling. 3 4. A projectile comprising-a solid bullet end carrying at its rear :1- flexible shell which provides a powder-chamber, said shell being reduced in size in the rifiin'g when the projectile is fired, and a primer-cap fitted into the month of said shell. 5. A projectile comprising a bullet end, a flexible shell integral therewith and enlarging therefrom and being reducible into the rifling when the projectile is fired, and a primer-cap frictionally fitted into the month of the shell. 6. Aprojectile comprisingasolid bullet end,

a shell integral with and enlarging therefrom and being adapted when the projectile is fired is fired becomes reduced whereby to closely fit the rifling and form a gas-check, and a primercap frietionally fitted into the mouth of the shell. In testimony whereof I have hereunto set my hand this 11th da of arch, A. l). 1901.
