3 0 US. Cl. 102-39 7 Claims Int. Cl. F42b /20 ABSTRACT OF THE DISCLOSURE A black powder charge for muzzle loader weapons which consists of an essentially cylindrical case of metal, preferably aluminum, which is provided at each end with an aperture formed by the rims of inwardly bent portions of the base; the metal case contains on the inside thereof black powder, and the two apertures are closed olf by closure disks of readily destructible material whereby the closure disks are held in position by the inwardly projecting rims of the casing.

Background of the invention With muzzle loader weapons such as deformation pistols and rifles or Weinberg pistols, a metered quantity of black powder is filled loosely into the barrel or drum aperture from the front and is sealed off by means of a plug. This method is quite complicated, quite apart from the fact that it presents considerable difficulties in complying with laws, e.g., the law of June 12, 1954, which requires a permit to purchase black powder.

Summary of the invention The aim of the present invention resides in considerably amplifying and facilitates the use and handling of black powder in connection with muzzle loader weapons and to assure the greatest possible safety. According to the present invention, this is achieved with a black powder propellant charge which is characterized by an essentially cylindrical case of metal preferably of aluminum, filled with black powder. At its end faces the case is closed otf by closure disks of readily destructible material, for example, cardboard, synthetic plastic material, celluloid or the like, which closure disks cover the black powder and prevent the black powder from falling out of the case; the closure disks are held in position by a ring-shaped inwardly projecting rim portion of the case.

These charges which can be made in the respectively required size, i.e., with a quantity of black powder matched to the respective requirements, fulfill not only the aforementioned aimed-at purpose but offer also the advantage that they are attainable by means of only a use permit as they satisfy the safety requirements of the pyrotechnic objects of Group IV according to German law.

Accordingly, it is an object of the present invention to provide a. black powder charge for muzzle loader weapons which eliminates by simple means the drawbacks presently encountered with the existing devices.

Another object of the present invention resides in a black powder charge for muzzle loader weapons which not only facilitates and simplifies the loading thereof but increases the safety of handling and use of the weapon.

A further object of the present invention resides in a black powder charge of the type described above which can be manufactured in a simple and relatively inexpensive manner for use by the customer.

These and further objects, features, and advantages of the present invention will become more obvious from the 3,424,087 Patented Jan. 28, 1969 following description when taken in connection with the accompanying drawing which shows, for purposes of illustratio only, one embodiment in accordance with the present invention, and wherein:

Brief description of the drawing The single figure is a cross-sectional view through one embodiment of a black powder charge in accordance with the present invention.

Description of the drawing Referring now to the single figure of the drawing, the metallic case 1, for example, made of aluminum, is provided with inwardly projected annularly shaped rims 2 and 3 at both end faces thereof. The black powder charge 4 is within the case and closed oil by means of disks 5 and 6, for example, made of celluloid. The disks 5 and 6 are held in position by the rims 2 and 3, respectively. The rim 3 is only relatively slightly bent inwardly during manufacture to assure that during the firing of the shot or the ignition of the black powder filling, it will erect relatively easily and readily releases possibly the closure disk 6 insofar as the latter has not been destroyed prior thereto by the effect of the powder gases, i.e., does not essentially impair the ejection of the closure disk 6. If so desired or necessary, the rim 3, of course, may also be bent inwardly more strongly, for example, in a manner corresponding to the rim 2 as altogether all the details shown in the drawing are to be understood only as illustrating of a preferred embodiment and susceptible of variations within wide limits according to the broad aspects of the invention.

The manufacture of the propellant charge takes place appropriately in the manner that at first the closure disk 5 is loosely inserted into the case 1 constructed with the rim 2 and thereafter the black powder 4 is filled into the same. The closure disk 6 is then placed on the black powder 4 and finally the case 1 is provided with a flange over rim 3 whereby care must be taken so that the closure disks 5 and 6 are sufiiciently securely clamped between the black powder 4 and the rims 2 and 3 so that they form a sufficiently tight closure preventing falling out of black powder.

While I have shown and described one embodiment in accordance with the present invention, it is understood that the same is not limited there to but is susceptible of numerous changes and modifications as known to a person skilled in the art, and I therefore do not wish to be limited to the details shown and described herein, but intend to cover all such changes and modifications as are encompassed by the scope of the appended claims.

I claim:

1. A black powder propellant charge for front loader firearms, especially detonator pistons in guns, comprising: an essentialy cylindrical metal case filled with black powder, having an axis and open at opposite axial ends; said case having inwardly projecting annular rim means at both ends, each defining an aperture; closure disk means made of readily destructible material, within said case, closing each of said apertures and sealing the black powder in said case for preventing a falling out of the black powder; said rim means holding said closure disk means in position.

2. The combination according to claim 1, wherein said case means consists essentially of aluminum.

3. The combination according to claim 2, wherein said readily destructible material is selected from the group of consisting of cardboard, synthetic resinous material and celluloid.

4. The combination according to claim 3, wherein one of said rim means extends radially inwardly substantially at right angles to said case; the other of said rim means is the forward rim and is smoothly turned inwardly at an acute angle with respect to said axis for ready return to the cylindrical shape of said case during firing to release the adjacent closure disk means gefore the release of the other closure disk means.

5. The combination according to claim 1, wherein said readily destructible material is selected from the group consisting of cardboard, synthetic resinous material and celluloid.

6. The combination according to claim 4, wherein said other closure disk means is planar and said adjacent closure disk means is concave toward said black powder.

7. The combination according to claim 1, wherein one of said rim means extends radially inwardly substantially at right angles to said case; the other of said rim means is a forward rim and is smoothly turned inwardly at an acute angle with respect to said axis for ready return to the cylindrical shape of said case during firing to release the adjacent closure disk means before the release of the other closure disk means; said other closure disk means is planar and said adjacent closure disk means is concave towards said black powder.
