Description
Sept. 27, 1932. e H. JACOBS CARTRIDGE Filed Sept. 1. 19:51
R O T N E V m moms . t storage and use with a mixture of greases Patented Sept. 27, 1932 N TED STAT PATENT .OFFICE- GEOBGE H. JACOBS, OF KINGS MILLS, OHIO," ASSIGITOR TO THE PETERS CARTRIDGE COMPANY, OF MILLS, OHIO, A CORPORATION OE OHIO caarmpen This invention relates to improvements in ammunition particularly cartridges of the type used in small arms. It is well known at cartridges are usually lubricated for having a low melting point or with an oil that isrli uid at ordinary temperatures. It is also well own that due to the physical prop erties of the lead bullet and the metal of the shell it is practically impossible to make a tight joint between the shell and. the bullet by crimping which is the usual method of connection. Thus it frequently happens that the cartridges are damaged or rendered use- 1 5 less because of the penetration of the lubricant into the powder and priming charge of the shell by way of the crevice or joint between the bullet and shell. This penetration to powder and priming charge may also oc-.
795 to provide a cartridge which is sealed against the entrance of molsture, oils, greases, and
corrosive vapors and gases and to provide an improved and highly suitable grease or oil-proof compound, the-sealing material being efficiently applied at the juncture of the bullet andshell and about the priming cup.
Cartridges which have been sealed may be stored in the chamber of the gun orin the magazine which may be liberally supplied with oil without danger of the oil seeping into i and saturating the powder and thereby deteriorating the cartridge. tridges, which have been sealed and then lubricated with awax or grease having a low melting point, may be stored at temperatures in excess of the melting point of the lubricant in view of the fact that even though the lubricant becomes liquid andmobile, there is no opportunity for'the lubricant to creep into the cartridge.
Other objects and certain advantages will be more fully apparent from a description of the accompanying drawing, in which:
Figure 1 is a longitudinal sectional view of a cartridge of the center-fire type showing on r p Figure 2 is a bottom plan view of the sealed Likewise carthe sealing, material applied at the joint of bullet and shell and appliedat the priming rimre cartridge.
Figure 3 is a-lon tudinal sectional view of a rim-fire cartri ge showing the sealing material applied at the joint of shell and bullet. j Figure 4 is a side view of a cartridge shown artly in section with the bullet-detached or illustrating the sealing material applied initially to the shell. i i
- Figure 5 is a view taken similar to Figure 4: but showing the sealing material initially applied to the heel of the bullet. Referring to the drawing, the shell is indicated at- 10 and the bullet at 11. In the instance of the center-fire cartridge as shown in Figures 1 and 2, a priming cup 12 is secured in a recess in the center at the underside of the shell and an aperture 13 afiord's. communication and contact between the priming mixture and the powder 14. The powder charge fills the shell with the exception of a space for the heel 15 of the bullet. Forthe purpose of attachment of the bullet to the shell, an annular groove 16 is provided in the bullet andthe upper edge of the" shell is crimped or clinched into this recess.
The sealing compound is ariplied as at17 to the joint between shell and ullet andfills the recess. This applicationofthe sealin compound after the shell is loaded is pre erable. The sealing compound is applied as at 18 about the priming cup filling or closing the lower end 0 the pocket or recess containin the priming cup. M v i i r n the instance of the rim-fire cartridge as shown in Figures 3, 4 and 5, the priming mixture 19 is contained at the base of. the shell withinthe rim portion 20 and no sealing is necessary at this point. For the purpose of receiving the clinched or crimped upper edge of the shell for attachment purposes, the annular groove 16 is included'in the bullet beneath the shoulder 21 of the bullet.
In this instance the sealing compound is' shown applied in a modified manner as a film 22 between the heel of the bullet and the 100 upper margin of the shell above the powder. It may be applied initially to the inner upper surface or mouth of the shell before the bullet is attached as shown in Figure 4 or it may be initially applied to the heel of the bullet before attachment within the shell as shown in Figure .5. I I v The most suitable sealing compound which has been found for this purpose is lacquer but there are other sealing compounds having similar properties which may be used. It is possible to use any of the quick drying oils dissolved in a suitable solvent; shellac dis solved in alcohol; or any of the condensation products dissolved in a suitable thinner. An
sealing compound which in the dryor ox1 I .dized state is resistant to solvent action of gum oils and greases may be used without 20 de arting from the concept of this invention.
Other lacquers, consisting essentially of nitrocellulose which have been rendered soluble by suitable solvents and to which have been added gums, plasticizers and oils may be used.
Havingdescribed my invention, I claim:
1.'A cartridge, comprising, a shell, powder and a priming mixture in said shell, a bullet protruding from the shell, and a film ofoil proof material disposed betweenthe bullet and shell. 1 I
2. A cartridge, comprising, a shell, powder and a riming mixture in said shell, a bullet protruding from the shell, and a film of nitrocellulose lacquer disposed between the .bullet .and shell.
3. A cartridge, comprising, shell, powder and a priming mixture in said shell, a bullet protruding from the shell, and a film of drying oil disposed between the bullet and shell.
. 4. A cartridge, comprising, shell, powder, bullet, said bullet and shell clinched together and a seal disposed at the crevice formed by said clinched connection.
5. In a cartridge, including the shell, powshell, a bullet attached in said shell, and an adhesive coating of oil and waterproof material applied between the bullet and shell for sealing the cartridge between these parts.
In witness whereof, I hereunto subscribe my name.
GEORGE JACOBS.
