PATENT FFIo SEWELL NEWHOUSE, OF ONEIDA OOMMUIIITY, ONEIDA, NEW YORK.
IMPROVEMENT IN METALLIC CARTRIDGES.
Specification forming part of Letters Patent No. 98,995, dated January 18, 1870.
To all whom it may concern Be it known that I, SEWELL NnWHoUsE, of Oneida Community, of Oneida, in the county of Madison and State of New York, have invented a new and useful Improvement in Percussion-Gap Cartridge-Case; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.
This invention relates to that class of metallic cartridge-caseswhere a percussion-cap is afiixed to the case for igniting the charge and consists, mainly, in the central arrangement of a movable anvil,to which the cap is attached, as will be hereinafter more fully described.
In the accompanying drawings, Figure 1 represents a longitudinal section of the cartridge-case, showing its construction, with the movable anvil in place. Fig. 2 is an end view of the case, showing the rear end of the anvil. Fig. 3 is an inside view, looking from the open end of the case.
Similar letters of reference indicate corresponding parts.
A is the flanged base of the case, with an interior collar, B. G is the movable anvil, the rear end of which receives the cap, and is larger than the stem 0, which stem passes through the collar B, as seen in the drawing.
The end of the stem is headed, by riveting or otherwise, as seen at D, so that it is con fined in the collar by such head, and by the shoulder at the base of the stem, the latter of which prevents the anvil from being driven through the collar.
The cap is placed upon the rear end of the anvil, and rests in the chamber in the cartridge-base, as seen in the drawing. The stem of the anvil is allowed free play longitudinally, from the collar B to the head D. The collar is perforated with three more or less) holes for conveying the fire from the cap to the powder. 0 represents these perforations.
The rear end of the anvil may bein any formangular, grooved, or flutedor the whole anvil may be tubular, so that the fire can be conveyed from the fulminate to the powder in the cartridge.
It will be seen that by this arrangement the anvil can be readily pushed back after the cartridge has been used and the exploded ca-p removed therefrom. A wooden stick, obtainable anywhere, may be used for pushing back the anvil.
The ditficulty of removing an exploded cap from a stationary anvil is a serious objection to the ordinary percussion-cap cartridge-case. By this improvement I have succeeded in overcoming that difficulty.
With the movable anvil the common percussion-cap is used, and after it expands from the explosion it renders the cap-chamber perfectly gas-tight.
. I am aware that movable anvils are not new, nor do 1 claim them as of my invention; but
What I do esteem as my invention, and desire to secure by Letters Patent, is-- A cartridge-case having collar B in the center thereof, perforated with two or more holes, e, in combination with a movable anvil having a head and shoulder, as shown and described.
The above specification of my invention signed by me. this 24th day of September, 1869. a
