Application tiled January 27. 1915, Serial No. 4,615. Renewed September 5, 1917.

To all whom t may concern:

Be it known that I, 'CLARENCE Gannon, a citizen of the United States, and resident of Fort Hancock, county and State of New Jersey, have invented certain new and useful Improvements in SmokelesS-Powder Charges, of which the following is a spccitication.

My invention relates io the 1mLnufacturc of smokeless powder charges, its object bcing to provide a forni of grain especially adapted for use in breech loading ordnance. l accomplish this by making the `grains in disk torni of such diameter as to lit the powder chamber of the particular caliber of gun. and of proper thickness,- and otherwise so shaped that `when superposed or built up into proper size for a gun charge, the disks shall be interspaced from each. other and partially spaced :from the walls of the` chamber, and alsoflongitudinally perforated, in a manner similar to other forms of grains.

Another important feature is the providing of an ignition charge of black powder to be fitted to the firing charge of smokeless powder just beforevinsertion into the gun, the black and smokeless powder beingikept entirely separate at all other times.

ln the accompanying `drawings forming part of this specification.

Figure 1 is-aeide elevation in partial cross section of a charge of my improvedpowder;

Fig. 2 is a plan view of the same;

Fig. 3 is a detail vertical section of one of the grains;

Fig. 4 is a sectional detail of a series of grains superposed upon cach other showing the ignition charge in place; and

Fig. 5 is a plan view of a single grain.

l'n` the drawings, Fig. 1 represents a charge of my improved powder made up ot a series of superposed grains A. and secured together by raw silk ribbons 2 passed through openings in the several. disks and tied as shown in Fig. 2. Each grain, (see Fig. 5) is formed preferably with a scalloped edge as shown. the maximum diameter beingsubstantially that of the chamber to which the charge is to be fitted. but leaving spaces around the periphery for the passage of gases in the combustion of the charge. IThe grain is also pierced longitudinally with a series of perforations 3 to facilitate Specication of Letters Patent.

combustion.y and is provided also on on(l face with knobs or bosses 4, and with corresponding sockets or depressions 5 on the reverse side which serve to inter-space the several disks when superi-posed` and also to hold them in mutually registering positions. In order to hold them in assembled position for a huilt-up charge. registering openings, preferably ot slittcd form (i. are provided to receive ribbons 2 tor holding the grains, thereby dispensing with the bags ordinarily used. lVhen so assembled and secured together the charge of powder can be stored in any desirable way, and be available for instant use.

For the igniting of the charge l provide a cylinder 7 of compressed black powder, having an axial combustion opening 8, the cylinder being of such size as to fit into the axial opening 9 in the several disks. It is obvious that the shape and dimensions of the disks or grains, and ignition charge may be varied at will to suit any conditions of use.

It is desirable in the forming of the regis- 1 tering bosses and correspondingdepressions or sockets oilE the disks,y in arranging the longitudinal perforations, and determining the thickness Vof the disks, to maintain throughout the entire charge when assembled as nearly as possible uniform thicknesses throughout the disks` and also of the walls or partitions between the perforations, so that the progress of combustion shall be substantially uniform throughout the charge.

In the shaping of my improved form of smokeless powder grain the compression of the colloidal mass, adds to the density and strength of the finished grains. thereby making them less liable to breakage, and the grains being of such diameter as to prac tically occupy the full diameter of the chamber are less liable to breakage from impact upon the walls.y than with other forms of grains.

While the preferred shape of the powder grains is that of a substantially plane surfaced disk, if desired they may be spherically or otherwise curved, or varied in other particulars, from a true plane and still embody the gist of my invention, which consists in making the powder grains of such shape that they may be assembled in a charge which as a Whole shall ron't'orni to the chamber oll the gun, and provided with continuous, longitudinal and lateral gas passages therethrough.

Having thus described my invention, what l clailn and desire to secure by Letters Patent is:

1. A gun charge ot smokeless powder comprising a series ot unit grains assunhled and detaehahly bound together in colleetive forni to fit the gun chamber,y having eontinuous longitudinal and lateral gas passages therethrough, and provided with an ignition powder element extending longitudinally therethrough.

2. A gun charge of .smokeless powder romprising a series of interloelied, inter spared, superposed,y unit dish' grains detaohalily hound together in eolleetire l'orni to fit the gun chamber` having continuons lonY gitudinal gas passages tlnretl]rough7 and having :in ignition powder element. in the l'orin ot a hollow cylinder fitting loosrliy in a longitudinal opening theretln'ongh.

A smokeless powder Charge,y Comprisw ing similar interlocked grains, tying devices confining them in assembled position, and an ignition charge removablyY arranged therein.

4. A smokeless powder charge made up of similar interloked grains arranged in a mass fitted to the gun eliamher. tying devices therefor, and an ignition charge arranged axially therein.

5. A smokeless powder Charge Comprising.` a series of interlocking dislelike grains` tying devices confining them in assembled position and an ignition Charge removablyY arranged therein.

6. A two-part gun charge comprising a propulsive element of smokeless powder ve cent grains eonlined in a mass to tit the gun chamber, and a distinct independent ignition elennnit oill lilaelt powder arranged as a core therein und extending longitudinalinY substantially therethrough.

7. A powder charge eoinprising two elements, viz: a proinilsive element` made up of smokeless powder grains oonlinod in n homogeneousl nnlss to fitv the gun Chamber and :in ignition element arranged as a. eorr therein and extending longitudinally soli-- stanti ally therethrough.

8. A two-part powder eli-rtree eoniln'ising a. propulsive element of smokeless, powder grains confined in a mass to titV the gun ehaniher and a seit-contained independent ignition charge arranged longitudinalljir therein.

Si. A two part ponder charge roinprising- :i propnlsire eleipenl ot srnilceless powder grains confined in a honiogeneons mass adapted to lit :i gnn-ehainher and an inde pendent ignition rliarge extending lungi tudinallyv snbstantialli' therethrough and itself having a tree air passage extending longitudinally therethrough.

10. A two part power charge comprising a propulsive element of smokeless powder grains confined in a mass adapted to fit a gun-chamber and an independent ignition charge extending longitudinallyT substantially therethrough and itself having a tree air passage extending longitudinalli7 therethrough.
