To all whom it may concern:
- Be it known that I, Jacquesv Dmmnor citizen of'the Republic of France, and resident of Paris, France, (post-ofiice. address 19 Avenue Parmentier,) have invented a new and useful Process of Manufacturing Gun- Powders, which improvements are fully set compatible with the weapon used. This increase in the progressive action has up to now been attempted with partial success by shaping the grains of the powder in such a way that the surface provided for the emission of gas instead of diminishing, tends to increase as combustion proceeds.
Other attempts have been made on other lines, which may be termed chemical. Here the object in view is to diminish the power and the brisance' of the powder, when it starts to burn, by superficial gelatinization, varnishing or similar processes; however, these processes only partially. attain their end. They are unsuitable for powders intended for use in heavy artillery and generally speaking these attempts have proved to be of little practical use, while at the same time, they are troublesome to carry out.
The problem has now been solved by forming heterogeneous powders in which there is a central core of a more brisant and v powerful character surrounded by a layer or sheet of powder which is less brisant and less powerful. In practice the following method is adopted A sheet of the more brisant powder which is obtained by ordinary means of manufacture is inclosed between two sheets or layers of less brisant powder. After having united the three (or more) of these layers of powder together (by the means hereinafter described) the resulting thick sheet is cut in the usual manner to the desired dimensions (disks, pellets, tablets, strips and the like). It has been found that perfect adhesion can be, obtained between the covering layers and the middle or core layer, b exterior pressure in the cold or warm eit er by means of a hydraulic press or by passing the Specification 01' Letters Patent. Patented Sept. 16,1919.
Application filed April 29, 1919. Serial No. 298,529.
more sheets of powder through suitably arranged rollers. In such case the union may be facilitated by coating one or more of the sheets with. a substance which acts as solvent for the powder.
The chemical composition and the thickness of the superimposed sheets of the core may be altered within very wide limits and allow the action 6., the commencement of combustion) of the central core to be controlled so that it takes place at the most suitable point in the bore of the weapon. Furthermore, the fact that the combustion starts with a less brisant powder considerably lessens wear and tear of the weapon as has been shown by the most recent researches of various investigators.
Finally powders with alcentral core coated with one or more superimposed layers of colloidal powder of a difl'erent composition from that'of the central core shows indisputable advantages from the point of view of progressive action and the lessenin of the wear and tear of the weapon in w ie they are used.
What I claim and desire to secure by Letters Patent of the United States is 1. The process'for the production of powder consisting in disposing an interior sheet of brisant colloidal powder between exterior sheets of less brisant colloidal powder said sheets being caused to adhere by any suitable mechanical pressure, the sheets being afterward cut into the desired shapes and dimensions. v
2. The process for the production of powder consisting in disposing an interior sheet of brisant colloidal powder containing nitro-glycerin between exterior sheets of less brisant colloidal powder said sheets being caused to adhere by any suitable mechanical pressure, the sheets being afterward cut 7 into the desired shapes and dimensions.
3. The process for the production of powder consisting in disposing an interior sheet of brisant colloidal powder containing nitro-glycerin between exterior sheets of less brisant colloidal powder also containing nitro-glycerin said sheets being caused to adhere by any suitable mechanical pressure, the sheets being afterward cut into the desired shapes and dimensions.
4. The process for the production of powder consisting in disposing an interior sheet of brisant colloidal powder between exhso terior sheets of less brisant colloidal powder said sheets being caused to adhere by passing them through cylindrical rollers, the sheets being afterward cut into the desired shapes and dimensions.
5. The process for the production of powder consisting in disposing an interior sheet of brisant colloidal powder between exterior sheets of less brisant colloidal powder said sheets being causedtoadhere by pressing them in a hydraulic press, the sheets being afterward cut into the desired shapes and dimensions.
6. The process for the production of powder consisting in disposing an interior sheet of brisant colloidal powder containing Intro-glycerin between exterior sheets of less brisant colloid-a1 powder containing nitroglycerin said sheets being caused to adhere by passing them through cylindrical rollers, the sheets being afterward cut into the desired shapes and dimensions.
7. The process for the production of powder consisting in disposing an interior sheet of brisant colloidal powder between exterior sheets of less brisant colloidal powder, coating certain of said sheets with a solvent for the powder said sheets being caused to adhere by any suitable mechanical pressure, the sheets being afterward cut into the desired shapes and dimensions.
8. The process for the production of powder consisting in disposing an interior sheet of brisant colloidal powder between exteror sheets of less brisant colloidal powder, coating certain of said sheets with a solvent for the powder said sheets being caused to adhere by subjecting them to hydraulic pressure, the sheets being afterward out intothe desired shapesand dimensions.
9. The process for the production of powder consisting in disposing an interior sheet of brisant colloidal powder between exterior sheets of less brisant colloidal powder said sheets being caused to adhere by any suitable pressure in the warm, the sheets being afterward cut into the desired shapes and dimensions.
10. A powder comprising a core sheet of brisant powder inclosed between sheets of less brisant powder.
In testimony whereof I have signed this specification.
