iAv. N. C. GAVARD.
' Cartridge. A I Patented April 19, 1870.
\ 77,67 rzess ADONIS' NICOLAS CRISTIN GAVARD, OF PARIS, FRANCE.
Letters Patent No. 102,109, mall April 19,i70
IMPROVEMENT IN METALLIC CARTRIDGES.
The Schedule referred to in these Letters Patent and making pert of the same.
To all whom it may concern Be it known that I, ADOSIS Niconas ,Gius'mx GAVARD, of Paris, France, have invented anew and useful Improved Metallic Cartridge; and do hereby declare the following to be a true and exact description of the same, reference being bad to the accompanying sheet of drawings, that is to say:
My invention relates to an entirely metallic cartridge, theshell of which consists of a thin steel tube,
unclosed, and perfectly elastic. The base is itself also formed entirely of metal. Constructed in this manner the cartridge can be used again, for the charge can be renewed as often as desirable.
The shell is formed by rolling a piece of sheet-steel upon a mandrel, the edges of the shell being simply placed in contact, or they'may be superposed or soldercd. In this last case they may be furnished with a longitudinal groove to give them elasticity. The metallic base, upon which is mounted the steel shell, may have a space formed therein cither applicable for lateral, annular, or centralfire.
I will describe, in connection with the accompanying drawing, the manufacture of the pin cart-ridge applicable for lateral lire.
1. The Steel Shell.
\ I cut from a thin sheetof steel, previously annealed, a piece, (1, Figures 1 and '2, corres mnding to the size ot' the case, one of the edges of the piece being inform a shoulder see Fi ures 5 and (i the shoulder d engaging in the groove i the metaflic base, as hereal'ter described.
A small recess, 0, is cut or stamped in the base of the shell a, for the percussion pin to pass through.
The shell, thus prepared, is tempered to restore the elasticity lost by annealing.
-: 2. Metallic Base. e
The base is formed of copper or other metal, asrepresented in Figures 7 and 8. It is, in the case of the pin fire system taken for example, a disk, f, having an interior cavity for theintroduetion of the cap.
Around the disk is formed'a groove, 9, in which is inserted the shoulder 11 of the steel shell a.
A hole, '1, is drilled laterally in this base for the. introduction oi the pin h .l. .lIcnntiug the Shell on the Base.
To mount the shell on the base the shell is opened so that the shoulderd enters the groove g, the elast-icity of the steel causing the said shoulder to remain securely fixed in the groove, (see the longitudinal section, Figure 9.) It is necessary to make the recess 0 in the shell correspond with the opening drilled in "the base, so that the pin may be easily introduced.
The complete arrangement of the shell, the base, the pin 11, and the cap I, is represented in Figures 10 and 1l,'-
' The .shape of the central aperture of the metallic base will vary according as the tire is intended to be lateral, annular, or central, and it will also vary with the species of fuhninate used.
This permanent metallic cartridge is applicable for all kinds of sporting and war arms of-any size that are Witnesses:
