Description
v HUNT. Cartridge;
Reissued Feb. 26, 1850.
UNITED STATES. PATENT OFFICE.
WALTER HUNT, OF NE" YORK, N. Y
ASSIGNOR TO GEO. A. ARROWSMITH.
M ETALL I'C CARTRIDGE.
Specification forming part of Letters Patent No. 5,701, dated August 10, 1848; Reissue N0. 164, dated February 26, 1850 To all whom it may concern:-
Be it known that I, \VALTER Helm, of the city, county, and State of New York, haveinvented a new and useful improvement in the construction of a metallic cartridge made entire with the ball, for fire-arms, which I term afrockct-ball; and I do hcrebyde'clare'that the following is a true and faithful description of the same.
The nature of my invention consists in making balls of metal for firearms with the of B (the cartridge) projects one-half of the ball C, which all together resemble the ordinary top thimble. Fig. 2 gives a longitudinal cut sectional view of the same, show-' ,ing the internal structure of the cap A, cavity D in the cartridge ll, andsits junction with the ball U. The dissected longitudinal cut section, Fig. 3, shows the cap'A separated from the flange or neck formed by the shoul; der at the dotted line F, upon the rear end of 13. which in form resembles the hiuese gong,
with a central perforation, F, in its discous head, which is the point of ignition from the priming. Over this'p-erforation upon the inside face of said cap is placed a thin waterproof tissue or seal(see Fig. 2) at the dot-' ted line G and. face .view, Fig. 6. This seal maybe made of any thin material through which the firc'from the priming may penetrate, and'which will at the same time secure the powder in the cartridge from escape or accidental injury. This ball. and thimble should bcformed in molds by pressure. The powder being well packed in the Cavity D, the cap A lined, with the seal G being fixed upon the flange, {MNLPI'BSSHI up to the shoulder E, should then be subjected to a second upressure, in order to fix the cap firmly and Fig. 4 is an end or face view of A,
charge.
.. produce a uniforlnity in the size of the cartridges.
It will be readily perceived that this plan of a "combined ball and cartridge is well adapted to firearms made to be charged at the breech, from the fact that in firing this ball'the cap A- is left in the breech, with its head or disk pressed'firm against the breech plug, and its rim or flange forced outward againstthe inner periphery 9f the caliber of the barrel, forming an air-tight stopper,
which effectually preventsall backward escape'o'f the powder, notwithstanding the,
breech-plug maybe loosely fitted in the-breech of the barrel behind the charge, which must necessarily be'the case in all reciprocating breech-pins, in order to prevent theinbin'ding from heat, deposits, 850., in rapid firing.
It is also obvious. that. in guns made. with :piseton breech-pins the cap A in my plan would be carried out forward of e'achsucceeding ball, operating as an effectual wiper-to the barrel at each discharge of the piece.
I am aware that balls have been made with a small cavity in the rear end thereof, to eon-v I tain a charge of fnlminating powder, or of fulmiuating-powder mixed with a small portion otlcommon gunpowdergand I am also aware that a metal cap with a hole in the center has been used to retain the charge in a cylindri cal paper cartridge attached to an ordinary ball, the cap being left, by the discharge, in
the barrel, and pushed out by the succeeding I do not therefore claim either of these as of my invention; but I \V-hlat I do claim as my invention, sire to secure by Letters Patent, is-- and de- Making metallic balls for fire-arms with the I rear part thereof cylindrical, and-acavity in the said cylindrical part of sufficient capacity to receive the entire charge of gunpowder, substantially-as herein described, when the said charge is retained inthe ball by a cap or the equivalent thereof, having a central hole through which the charge eanbeinflamed', substantially asdescribed.
