IMPROVEMENT `In cARTRmeE-sHELLs.
Specification forming part of Letters Patent No. IQLMB, dated May 29, 1877; application filed October 24, 1816. j
cityof London, in the Province of Ontario,- Canada, have invented certain newand us'eful Improvements ou Cartridge-Shells and I hereby declare that the following is a full, clear, and exact description of the same.
The Object of my invention is a detachable cartridge-shell, thecase or tubepart 'being distinct from the base or back end, and to which it may be readily attached, so that after being used the case or tube may be detached from the base and thrown away, and a fresh case fitted to the old base, thereby preserving the most expensive portion of the shell, instead of `throwing the whole away, as heretofore.
1u the accompanying drawings, Figure 1 is a drawing of the base, detached. Fig. 2 is 'a drawing of the case, detached. v Fig. .3 shows the two put' together. Fig. 4 shows the case A is the case or tube, made of paper or other material, and which, in the first place, is Wholly distinct from the base B. y The latter is made of brass .or other suitable material, and contains the percussion-cap'. One end of the case has a thread or screw formed ou the outside, and also a shoulder, b, as shown at Fig. 2. The base B has a corresponding or female thread formed ou the inside to receive the threaded eud'of case A.
'When the case is inserted and screwed into I the base, the remaining portion of the case,
from thelshoulder b to the outer end, is exactly even with the outside of base.
. This shoulder Or-iiange isI milled or'rougheued in order to act as a thumb-piece in screw- Y ing the two together.
When pliablematerial is used for the coustruction of the case. the act of screwing it on or iu a threaded base will cause the 'formation of a thread sutcieut to maintain itin position.
From the above description it will be seen that the case and base may be manufactured and supplied distinct from each other; and, that any number of cases may be fitted to a single base, thereby effecting a material saving iu cost, and as the cases may be iiattened and packed closely together, Fig. 4, the bulk and weight, in transportation, willbe reduced, and a large number maybe carried on the person without inconvenience.
What I claim as my invention is- The cup-shaped, base'B, provided with in- I ternal screw-threads, as described, in combi., nation with the paper. shell A, the two being secured together by screwing the end of the tube into the base, substantially as specified. Y
