SECIFIOATION forming part of Letters I'atent No. 670,728, dated March 26, 1901.

7 Application tiled December 27, 1900. Serial No. 41,197. (Nomodeh) To all whom it may co'nccrw 7 Be it known that l, HUGH E. POOL, a citizen of the United States, residing at Rainy, in the countyof VVashita-and TerritoryofOkiahoma, have inventedcertain new and useful Improvements in.Projectiles for'Firearms; and I dodeclare the following to be a full, clear, and exact description.of the invention, such as will enable others skilled in the art to which it aonertains to make and use the same.

My intention relates, to improvements in bullets or projectiles for firearms; and the object thereof is to provide a projectile which dispenses with the use of a cartridgeshell and obviates the loss of time and inconvenience attendant upon discharging the same from the arm and which is also adapted to receive a plurality of impulses to increase its range and'eifectiveness.

\Vith this and other minor objects in view the invention consists of'certain novel features of construction, combination, and arrangement of parts, as will be hereinafter more fully described,and particularly pointed out in the appended claims:

In the accompanying drawings, Figure 1 is a longitudinal sectional view of a projectile constructed in accordance with my invention. Fig. 2 is a detail perspective view of the fulminate-oap and its stern. Fig. 3 is a detail sectional view of the same.

Referring now more particularly to the drawings, the numeral 1 designates my improved bullet oriprojectile, which is constructed of two sections 2 and 3,whioh for convenience ofdescription I will term the body and point of the projectile. The body 2 in practice is to be made longer and heavier than the point 3 to adapt the projectile to carry well and to also adapt the secondary charge of powder or other explosive to exert its full expansive force on the point-section, as hereinafter described. The point-section is provided at its rear end with a rabbet 4, Williii fits within and releasably connects it with the forward end of the body-section.

'lhc body-section 2 is provided at its front and rear. ends with chambers 5 and G to receive a primary and a secondary charge of powder, and a longitudinal bore or passage 7 connecting said chambers. The charges 8 and l of powder contained within said chambers may be and preferably are of the Smoke less variety; but Imay employ in lieu thereof any other kind of explosive or expansive gas suitable for the purpose. A cap or receptacle 10 to receive a charge of fulminate is arranged within the primary charge chamber 5and is provided with one or more openings 11, communicating with said chamber, and a tubular 6o stem 12, said stern being in open communication with the cap and bore 7 and fitting within the latter to hold said cap supported coucentrically in the axial li-neof chainbe 5. Through this tube and through the borebr passage 7 extends a time-fuse 13, which is ignited by the fuiminate to fire the secondary ,charge 9.

In operation after the projectile has been placed within the barrel of the firearm the primary charge 8 is fired in the usual mannor by the firing-pin striking the cap 10 and explodingthefulminate therein, whereby the' projectile is sped from the arm. At the same time the fuse 13 is ignited and in a predetel-mined time fires the secondary charge 9, whereby the point 3 of the projectile is discharged from the body 1 and is caused to traverse a greater distance. By this construction and mode of operation it will thus be seen that I attain the twofold advantage of dispensing with the usual cartridgeshell and securing greater range of the projectile, whereby valuable time in loading is saved and the eifectiveness of the projectilemate-fis rially increased.

Changes in the form, proportion, and minor details of construction may be made within the scope of the invention-Without departing from the spirit or sacrificing any of the 'advantages thereof. I

Having thus fully described myinventio'n, what I claim as new and useful, and desire to secure by Letters Patent of the United States,

1. A projectile for firearms, comprising'a body-section having primary and secondary explosive-charge chambers, a point-section releasably connected with 'said' body-section 3 and adapted to be projected therefrom by 106 said secondary charge, and means forsuc-,-.- cessively firi ng said charges, substantiallyas set forth.

2. A projectile for "firearms, comprising-a} body-decision having at its oppositeende primeeting said chambers, substantially as sub I0 mary and secondary explosive chambers and forth. a passage between said chambers, a point- In testimony whereof I have hereunto set seciiion releasably connected with said hodymy hand in preeence of two subscribing \vi1, 5 section and adapted to be projected therefrom neeses.
