SPECiIFIGATION forming part of Letters Patent N0. 7151,519, dated February 9, 1904.
Application filed Au ust 5, 1903.
To all whom it may concern:
Be it known thatI, JOHN HENRY Klnznaa citizen of the United States',-residing atSeward, in the county of Seward, Stateof Nebraska, have invented certain new and useful Improvements in Cartridges; and I do hereby declare the following to be a full, clear, and
the velocity of a projectile with a minimum of increasedstrain on the gun.
In the drawings forming a portion ofthis reference indicate similar parts in both views, Figure 1 is a section takenl longitudinally through the barrel of. a gun, showing a loadembodying the present invention Fig. 2 isa longitudinal section of a cartridge embodying the present invention. a s
Referring now to the drawings, and more particularly to Fig. Q-thereof, there is shown a. cartridge including a shell 5' of ordinary form and having a cap 6 in its rear end. Inn
the shell is first placed a quantity of powder .7, on top of which is adiaphragm 8, having a central perforation 9, this diaphragm being of extremely light material, such as very thin metal, or'paper, or felt. Upon the diaphragm 8 is placed an additional quantity of powder 9, and upon this powder is disposed a projectile 10, which is secured in the end of the shell in the usual manner.
W Vhenthe cap is exploded, the diaphragm,
Serial No. 168,338; (No model.)
the powder 9, and the projectile 10 are started in the diaphragm and adds the force of its expansion to increase the velocity of the pro" jectile. When very thin metal, such as tin- 1 foil, is used, the second explosion follows quickly after'the first explosion and the heat from the first explosion destroys the'tin foil,
so that the entire surface of the second charge of powder is exposed and its combustion 'most rapid. v v In Fig. 1,0f the drawings there is showna gun-barrel loaded directly with two charges 'of powder and an intervening diaphragm and with a projectile, the gun-loarrel-being shown at 10, thecharges of powder'at 1 1 and 12, the
diaphragm atf13, and the projectile at 14.
The action in this case is the same as in that above described.--
What" is claimed iss cartridge comprising. a shell having a cap at its rear end, a chargeof. powder in the end of the shell adjacent to the "cap, a thin fusible inetallicdiaphragm 'disposed transversely Within the shell against said charge ofapowder, said diaphragm having a central perforation, a second charge of powder in the shell against the diaphragm and a projectile in the shell against the second charge of powder.
In testimony whereof I aflix my signature in presence oftwo witnesses.
' JOHN HENRY KILZER.
