HENRY CBULL, OFBRCKLYll, NHV YRK, ASSlG-NR F GNR-Edif? liiS RIGHT TG WM. L. HEASLEY, F SAME PLAGE,
Specification forming part of Letters Patent No. d, dated Auguct B, 1876; application filed December 1S, 1875.
To all whom it may concern:
Be it known that l, HENRY G. BULL, of the cityof Brooklyn, county oi Kings, and State et' New York, have invented a new and useful Improvement in Central-Fire Cartridges for Fireurrns; and l do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the gures and letters marked thereon, and in which- Figure l is an eaterior view of the cartridge; Fig. 2, a longitudinal section of the same, iu the line of the axis; Fig. 3,' a longitudinal section cf the central tube in the line of its axis, together with the anvil and cap for the fulininate; Fig. d, the central tuhedetached. Y
The same letters ot reference are used to designate the same parts in all the figures.,
'The nature and object of my invention are to produce perfect combustion of the powder within the cartridge, which result l accomplish by conveying the tire from the iulniinate into the axis of the cartridge by means ot' a small perforated or slotted tube, thus igniting the charge in numerous places simultaneously.
To enable others skilled iu the art to nia-he and use my invention, I shall now describe the construction and operation ofthe saine.
I take the ordina-ry metallic shell-cartridge, as shown in Fig. 1, in which A is the shell and B the projectile, and place in its axis the small perforated tube C, (shown detached in Figs. 3 and 4,) which should be ol" thin metal, or other suitable material, and the perforatione of which should be smallerthan the grains or' the powder with which the shell is charged; or, if preferred, narrow slots may be used instead of the small holes or perforations.
The powder is filled into the shell A, around the central pcrlbrated tube (l, and then the projectile B is set into the shell against the inner end of this tube, as shown in Fig. 2. A small piece ol' metal, called the anvil, a i'ront View ol' which is shown at' ll in Fig. 3, and an edge View at lil in the saine ligure, and the cap G, containing the fulininate, (shown in section in Fig. 3,) are' secured in a small can# ity in the end ot' the cartridge, as shown at G in Fig.` 2, which cavity has au opening into the central. perforated tube U, for the passage of the lire; or the cavity il may be formed at the center ot' the inner side et the head ot the cartridge, and have the fulininate deposited in or attached'to it opposite to the operi end of the inner tube; or the fnlminate may be attached to the rear end of the central tube, or in such Wise that the hammer of the lock shall strike against and explode the fulmiuate.
The cartridge, bein g thus prepared and loaded, is placed in the chamber ot' a breechloading lire-arm, and ou drawing the trigger' the hammer of .the leek. strikes the cap G, exploding the fulminate and forcing the fire into the central tube (l, and, through the pern` forations of this tube in all directions, into the charge by which it is surrounded, producing a perfect, entire, and simultaneous combustion of all the powder behind the projectile or ball, thus giving to such projectile or ball a greater velocity and range than it is possible to obtain from the same weight end quality of powder when only partially consumed in the discharge, as is now the ease when heavy charges are used for long-range practice; and thus also keeping the barrel of the picco cmnparativcly clean, and capable of being used for a much longer time than can be donc by any of the modos heretofore in use for firing the charge.
l do not limit myself by this specification to any particular forni of shell; uor that the shell shall lle metallic in its composition; nor to any particular forni or order oi' the perforations or openings in thecential tube; nor that thc central tube shall pass entirely through the charge of powder iu the shell; nor that thc [irc ol the fulniiuateshall directly produce the combustion of the powder in ter-re cartridges, what `I claim therein as vided with a 4percussion-eep or fulmnete at new, and desire to secure by Letters Patent ot' the rear end, substantially as herein described, the-United States, is-
.A cartridge for breech-loading tire-arms, `HENRY G. BULL. having an inclosing case or shell, and-an iu- Witnesses: terior or centra perforated or slotted tube ex- OCTAVE WHITTAKER, tending tothe base of the projectile, and pro- J CHN HARRISON.
