SHQTG'UN SHELL.
Application le. January 20, 1919. Serial No. 272,130.
To @ZZ 'whom it may concern:
Be it known` that I, EARLE M. Barrows, a citizen of the United States, resident of Minneapolis, county of Hennepin, State of Minnesota, have invented certain new and useful improvements in Shotgun Shells, of which the following is a specification.
The object oi my invention is to provide a shot or scatter-gun shell which has con; tained Within itself a tracer projectile or capsule, distinct or independent from its ordinary load of shot, which projectile or capsule is so designed that upon tiring it will accurately follow the center of trajectory or pattern of the multiple shot charge and leave a trail of tire, smoke or vapor in the air to indicate the path traversed by the shot charge and enable the person using the gun to correct any inaccuracy of aim.
L further object is to provide a shot or scatter gun shell which has contained. Within itself a tracer projectile or capsule, distinct from and independent ci its ordinary load, which projectile or capsule is so designed that upon tiring it will accurately follow the center of trajectory or pattern of the multiple Shot charge and at a certain predetermined range or distance from the muzzle of the gun, Will give forth a burst of nre, smoke or vapor in the air to indicate the path in which the shot charge is traveling, and so also indicate by comparison with the p oint at which the burst is discernible the range or distance of the target or object from the person using the gun enable such person to correct inaccuracy oi aim or misconception of range.
il. further object is to provide i designed 'for use for either ticle, wine* shooting purposes.
@ther objects or" the invention will appear from the following detailed d mription.
rlhe invention consists generA 'f' ons constructions end combinati hereinafter described and particularly pointed ont 'the claims.
the accompanying drawings 4Ao'rmimg or this specification,
fr .my il a c ctionai i Wad aL other modilication of the wad and projectile or capsule, showing a form of superimposed Wad,
Figure 5 is a sectional view of still another modification of Figure 2,
Figure 6 is a horizontal sectional View of Figure 3 0n the line 6--6 of Figure 3.
ln the drawing, referring to Figure 1, l represents the paste-board shell-case of a standard shell. 2 represents the brass shell base, 3 the base wad, 4 'the primer, 5 the powder space and powder, 6 the shot space and shot, and 7 the shot Wad. 8 represents the powder wad, of "telt or other fibrous material, which will expand or contract in passing through the barrel of the gun. 9 represents the metal projectile or capsule. l0 is a Weight or'a lead. or other heavy metal in the projectile or capsule. 1l is the sniolre composition, preferably or gunpowder, an oxidizing magnesium, and a. binding agent suoi-' s shcilac, but any other material for accomplishing same result may be used. l2 is a fuse or slow match, preferably ci: porous paper, impregnated with saltpeter, but any other material for accomplishing the saine result muy be used. 20 is a shoulder on the projectile or capsule, designed to reduce gas leakage and giving c greater hearing against the shot charge.
Upon the discharge oie the shell through the action of the primer 4 the powder ignites, producing a large volume of gas and great heatu This resses the Wad d and the proiectile 9 fiori carrying the shot nl The resistance ot charge holds the tracer the wad. 8, the two her-rel ci" the ssure exploding he heat of the slow match the muscle s resistance o' the and shot wad i" hetero them. of inertia powder or trie sh discharge ign l2. is i shi 'full speed is a inertia becorn f in l er;

'Mill projectile and to which has been ignited by the burning powder charge, the fire therein reaches and 1gnites the smoked composition which becomes visible through a trail or burst of smoke `or fire so that the person using the gun can readily determine the direction of the discharge and by comparison with the poin-t already known at which the tracer trail or burst appears, can determine with accuracy the range of the target. In this invention I do not, however, confine myself to the use flight of the tracer projectile, or the slow match or fuse may be cut down so as to merely delay the ignition of the smoke composition, so that there will be no smoke therefrom near the muzzle of thel gun to obstruct the vision of the marksman.
In Figure 2 I have shown a modified construction of the wad'and tracer projectile in which 11a represents the space to -be filled with the smoke compound or the compound and fuse. The shoulder 20 of the metallic tracer projectile 9 is here shown recessed into the wad 8. The weight 10 in the tracer projectile of lead or other heavy metal is designed to aid in the Hight of the tracer prevent it fromtumbling. l3is a metallic cylinder attached to the wad 8 and designed to produce a more perfect bore from which the tracer projectile 9 is fired. The hollow cylinder or bore lining is provided with a shoulder la to aid in holding it in position in the wad 8.
Figure 3 shows a modification ol2 Figure 2, in which the shoulder or rim 20 on the tracer projectile is omitted. The metal bore 13 is further provided with spiral groove rifling l5 into which fit projections 16 provided on the tracer projectile. Upon discharge of the tracer projectile the grooves or riling sets the tracer projectile spinning or rotating on its longitudinal axis and tends to increase its accuracy and prevent tumbling.
InFigure lthe weight 17 is madeintegral with the tracer projectile 9a. Shoulders 18 are also provided at the base of the tracer projectile to reduce the size vof the opening into the smoke composition chamber and prevent too rapid combustion of the smoke composition. A fuse or slow match is also shown, but may be omitted. The shoulders on the cylindrical metallic bore are also omitted, the bore being held in place in the wad 8 by a suitable glue composition or by compression. There are also shown wedgeshaped wads 19 and 19, imposed above the wad proper 8 and its tracer projectile 9*. These are for the purpose of reducing gas leakage. Upon reaching the choke of the gun barrel the greater friction and resistance on the thick edges of the wad causes the thin edffes to turn outward in a hingelike manner, al vowing the tracer projectile 9a an unobstructed flight.v These wads may be superimposed on any of the designs shown, there being no change produced thereby in the mechanical operation of this invention as in the case of the plain wads. The heavier. tracer projectile drives them out of the way without seriously being deflected in its flight.
In Figure 5 have shown a modification of Figure 2, with the wad 8, the tracer projectile 9 and the shoulders 20, the weight l0, the smoke compound chamber 11a, the metallic bore 13 and shoulders 14, and it is also provided with indentations 2l cut in 'the base of the tracer projectile 9. These may be varied in shape and are designed to steady the tracer projectile in its flight in the same manner as the feathering of an arrow.
In various ways the device herein described may be modified and the parts shown may be combined and still be within the scope of my invention.
I claim as my invention:
