To all whom it'mayc oiwcrrtl 'a new and usef'ullmproi emen tin Cartridges, which inventionv is fully lowing specification? rangement of said lateral vents being such as v to secure the simultaneous completion of combustion throughout'the charge. In the pres cnt invention I form a cartridge charge of a plurality of concentric cylinders, each of which may be provided with lateral ventchannels, affording an escape for the gases in alateral direction, and the additional burning-surfaces, as in the application referred to, and I also divide the cylinder longitudinally,

the lines of division being so arranged as to break joints. With cylinders thus composed of longitudinal sections the internal pressure of the gases of combustion will cause the sections to spread or expand rad ially, thereby openingthe joints between the several sections ofany given cylinder and aifording lateral vents for the gases withinfthe cylinder and exposing the surface of the joints to the flame of ignition; with this construction the necessary lateral venting to avoid disruption of the charge is' secured even in' the absence of lateral perforations, as well as the simultaneous completion of combustion of the entire mass of explosive. It is desirable,'however, to provide such lateral perforations in many instances,

as well as cells or holes in the walls of the,

Fig. 3 shows one of the longitudinal sections into which each cylinder is divided, and Fig. {L is a side elevation of Fig. 1. v

Referring to the drawings, 1 indicatesa pludivided into longitudinal sections 2, with the joints 3 between the sections soarranged that joints of adjacent cylinders shall not'lie in By this arrangement I break the joints between the sections of the adjacent cylinders.

As shown in-Figs. 2 and '3, each of the ion- .gitudinal sections 2 isprovided with a pin ralityof lateral perforations 4, preferably extending radially through the section, and a plurality of cells 5', also extending, by preference, in a radial direction into but not through the body of the sections 2. In Fig. 1 I have shown the radial perforations 4; without the present'i riyenl' rality'of concentric cylinders, each of which is cells, the walls of the several cylinders in this case being so thin that the-adjacent radial perforations are substantially the same dis- 5 tance apart as their inner and outer ends, and hence the cells are not needed. The perforations 4 act not only as lateral vents, but also adord additional burning-surfaces, while the cells 5 act onlyto'increase the burning-surface, Since both the perforations 4 and the cells 5 adord burning-surfaces, it'is desirable that they'should beso arranged with relation to each other a'snot to interferewith thesim'ultaneons completion of combustionthronghout the mass of the charge, and for this reason the cells dand' perforations are uniformly distributed, so as to provide substantially equal thicknesses of material between each cell or perforation and adjacent cells or perforations, For the purpose {of securing provided 15' tions.

the several sectional cylinders assembled as shown in Figs. 1 and 2 they may be bound by cords 6 or secured in any suitable manner.-

It will be obvious that a charge formed as 5 herein described will be one of great cornpactness, thereby securing greater density of loading, and that the charge will possess sufificient rigidity to-carry the projectile, if desired.
