Specification forming part of Letters Patent N0. h,fl6), dated August 1, 1876; application filed May 24, 1876; I

To all whom it may concern: I

r Be it known that we, NAPOLEON B. WELSH and GEORGE W. EVANS, both of- Baltimore, in the county of Baltimore and State of Maryland, have-invented certain new and useful Improvements in Cartridges; and we do hereby declare that the following is a full, clear,

form a part of this specification. I

This invention relates to that class of cartrid ges that are used for breech-loading guns andit consists in the construction, and its combination with the tube or shell of a cartridge, of a recessed base-block orplug, having a conical tapering po-wder-chamber,: substantially as hereinafter mores-fully explained,' and pointed out in the claim.

In the drawing, Figurel 'lrepreseuts a vertical section .of a. cartridge having our im-V provement. I w

We have represented a longitudinal ofa cartridge having'our improvement.

'A is the tube or body of the cartridge, which is'open at, both ends, as shown. B is a cylindrical plug, having an interior recess or powder-ch'auibeiyB, of the shape of an inverted cone, tapering to a point at'c. ".Eheplug B has an ofl'set or shoulder, b,. above the rim or flange c, this oflset being of a depth equal-to section against it, so as to make the exterior of the cartridge from its top to the rim a perfectly smooth'and cylindrical.

The advantage of this construction is that that part of the cartridgc-viz., the bottom part-which, when the cartridge is inserted into the breech, is surrounded by the joint ,between the breech-block and breech, is perfectly solid'and in one piece, whereas in cartridgesjofi-this class, where the paper tube extends all the .way down to the 'rim c,"the paper is apt, to become injured'and abraded by, the friction between it and the-breech and breechblock in loading Having thus described our improvements,

ent of the United States- The combination of an open cartridge shell or tube, A, with the cylindrical base-block or plug B, havinginternaltapering powder-ch {1111b ber B, annular shoulder or offset 1), and bottom rim or flaugec, substantially as and for the purpose herein shown and specified.

In testimony that we claim the foregoing as our own we have hereto alfixed our signatures in presence of two'witnesscs; x
