' in that portion of this instrument wherein- STEPHEN BIRD, or CAIRO,- ILLINOIS.

. l Be it known that I, STEPHEN BIRD, a citizen yof theUnited States, residing at Cairo, inv the county ofv AlexanderV and State of Illi-l Vnois, have inventedV a new `Vand usefulV Shot- A Case, of which the follow'ingis aspecica- A tion. Y The objects of the-'invention are,;generV ally, the Vprovision in 'a'. merchantable Vform of a device of theqclass 'abovel mentioned j whichshall be inexpensive to manufacture', Y. facile inbopreration, and devoid Vof'` complii' cated parts; specifically, the provision of 'a shot'c'asey adapted` togprotect theV boreV of a fire armagainst; the-attrition `of a shot charge Vasthe same passes out of the barrel; the provision of a shot case adapted to sweep thel j bore of the fire arm clean from the products *of the'co/mbustionA ofthe explosive, at each shot; the provision ofashot case adapted; to jx 4 '.-hold the shotrtogether in solid bulk as they` Y leave the muzzle ofthefarm, lgiving-thel load increased penetration, and to register Y a- V'closer pattern upon a target; the provision cfa shot case so constructed, that, wheny it canino longerovercome the dispersiveelfort -jf'gofthe shot, it will separate laterallywithout vdistorting :the contour of the shotcharge, totherand' further objects being ,madefmanif fest hereinafter as the description lof the'` invention progresses. f

The invention consists in g Ythe novel 'conV` patentable novelty isclaimed for certain il" .1 distinctive and peculiar features of vthe'device, it being understood'that within vthe scope of what hereinafter is thus claimed,

divers changes in the form, proportions, size and minor V,details of the structure may be 4^: j made, without'departing'from the spiritory sacriicing anyl ofthe advantages of the in-VV vention. v l

Similar numerals of reference are-emr ployed to denote corresponding'- .parts I i throughout the several figuresof thedrawings.

In they accompanying drawings, Figure 1 shows in longitudinal, section, a shotgun shell equipped vwith the shot Ycase of my invention; Fig. 2 is a transverse section on the line A B ofv Fig. 1.; Fig. 3 is a plan of the strips which IV employ in making the shot' case, 'the ends `of saidV strips being vover- A i, Spec-iincation of Letters Patient.` ]a,13e1113ed Aug'.

prising a2 paper body 1 equipped 4withl a lmetal base 2 carrying a primer 8. Into'this f shell may be inserted a nitro powder. charge, or other explosive denoted by the numeral 1Q. Upon the explosive charge is superposed aY card wad 4, and upon the card wadv 4 aresup'erposed felt wads 5 and 6, the object `of ,theV cardjwad being to prevent the lubricant Vin the wads 5 and 6 from deteriorating Vthe powder, and further to prevent' the tearing of the wads and 6 when the charge iszexploded. Another card'wad 7 is superposed vupon Vthe felt wads 5 and 6. Ahead of Athecard Ywad k7 in theshell is 4mounted the shot ca'se of my invention withv in which is inclo'sed the shot 8, va thir'djcard wad 19 being superposed upon the shot and Athe shot case; at its extremity, the shell, presupposing that a'p'aperV shell has beenv used,

is crimped upon the wad 9 as denoted by the numeral 11. y y l Y Y In loading a shell, I insert the explosive and the intermediate wadding thereinto. I then take two strips 12 of flexible material, preferably some textile substance, and overlap 'their ends slightly, as denoted by the numeral 14 in Fig. 3. vThe overlapping ends.'

14 are then inserted into the mouth of theshell and rammed downupon the wadding which rests upon'the powder or other explosive. When the strips 12 are thus rammed into the shell, their sidesfwill overlap as denoted by the numeral 15 in Fig. 2. The device as thus far constructed, consists of a tube of flexible material closed atV its inner end.; Into the tube thus formed Ivincase being overlapped as denoted vby the nusertthe shot charge, the ends of the shot i crimped in the usual manner, when a paper shell has been employed. The length and the width of the strips l2 will be determined by the caliber of the shell and by the volume of the shot S, it being understood that the said stiips are to be wide enough so that their sides may overlap to form a tube, and they are to be of sullicient length so that their ends will overlap to the rear and to the front of the shot charge.

lVhen chilled shot used iii a fire arm having a cylindrical bore the attrition and consequent injury to the interior of the barrel caused by the passage of the shot, is no ticeable; when a tire arm having a modified choke is subjected for a considerable period to the action of chilled shot, the injury is inoi'eniarked; and when chilled shot is used in a full choke bore, the arm deteriorates rapidly. This injury to the bore of fine fire arms by the use of chilled shot, is obviated when a` shot case constructed in accordance with my invention, is employed, the said case serving to protect thoroughly and effectively the bore of the arm against the attrition of the shot.

It is well known that nitro powders in their combustion will liberate substances which when allowed to remain in the bore of the arm cause the same to become pitted in a short time. The shot case of my invention is preferably fashioned from textile material and in its passage through the bore ofthe arm, will sweep from the said bore,

any deleterious material which may have been deposited therein by the last discharge.

rlhe shot case serves to confine the shot` charge in a compact bull: as it leaves the muzzle of the arin, and when the said shot case can no longer withstand the dispersive effort ofthe shot charge, the said case will separate laterally into two parts without unduly distorting the shape of the charge.

From the foregoing it will be seen that the shot case not only serves to confine the shot but, as well, that when the time finally arrives, for the. shot charge and the shot case to be separated, the separation is' effected in such a` manner that the pattern which the shot will leave upon a target will not be rendered irregular, `the shot being evenly and fairly distributed over the suis face upon which it inipinges.

So fai' as I am advised as to the state of the art, it has been common heretofore to inclose shot charges in cases which must be blown apart bodily, or separated longitudi- `nal`ly in the diiectioii of the line of flight Having thus described my invention what l I claim as new and desire to protect by Letters Patent is:

l.. it device of the class described. fashioned from laterally separable strips of flexible material having their ends overlapped, the strips being transversely bent to form a closed case. i

2. A. shot case fashioned from laterally separable strips of flexible material having theirends overlapped, the strips being bent" transversely to bring their sides into overlapping relation throughout the length of thecase.`

3. A shot case fashi ned from laterally their sides overlapped throughoutthe length ofthe case to forni a tube, the ends of the strips being overlapped to. close the ends of the tube.V

4.111 a device of the classdescribed, a`

shell an explosive disposed within the shell; a wadding disposed within the shell upon the ex )lesivea` shot case dis iosed within and shot disposed within the case; the said case coni-` tlie shell upon the wadding;

prisiiig separate strips of flexible material having their sides overlapped to form a tube fitting closely within the shell, the strips at one end being overlapped upon the wadding and at the other end overlapped upon the shot.

5. A device of the class described fashioned from laterally separable strips of flexible material transversely bent into overlapped relation, and terminally bent to forni a closed case.

`In testimony that I claim ,the foregoing as my own,.I have hereto affixed my signatui'e in the presence of tivo witnesses.
