YAnother general object is' to provide a conitainr ef this improved nature which, .though rmtai'iiing' more and larger cartridges than the 'nwsal aircraft ammunition container',A will not bc 3p ofirtiii'tely harder t0Y handle 0r install in place in the aircraft; and will instead, be Veven easier to install, at least under certain circuni-y stances, which circumstances will be hereinafter inside manifest. It i`s` also an object of the' invention to provide ai caisson, and its concomitant structureintlie rli'lance carrier, which will renderit possible employ a new and improved mode ofinstalling caissons, ammunition containers, and magazines, especially in aircraft. y
AA particular object of the inventionY is to profl vide'y a' container so constructed that the weight of the cartridges in the vcontainer will `be so bal-Y anced that theywill, contrary to the usual practice, tend to remain in a state of stable equilibev rium, and not shift about, even during installing of other handling, and regardless ofthe position `or attitude of the box; and, withal, without necesi 's'it'ating any special retaining device, as for pref' v entingthe cartridges or the ammunition belt ,from slipping out of the container during handling.

Thi-)drawings s craft` structure; concerned with the @lisais f ai air; e .msg iha ae' directa ammunition bei; that is to 2,506,409 'l ,f c
say, they show a substantially cubic caisson-well 3D. formed between two adjacent ribs 3|, 32, of said wing; a detachable door 33, closing the lower opening of said well; a pair of aligned upper fittings or brackets 35, riveted to the rib 32; an aligned pair of lower hooks 36, likewise riveted to the rib 32; an aligned pair of lower fittings or open sleeves 31, riveted to the rib 3l; a pair of upper brackets 38, carried by one of the spars (not shown) of the wing so as to embrace laterally, the uppermost portion of the box I I, I2, I4; and an armor plate 39, xedly mounted in the wing to the rear of said box. An opening 40 is provided in the rib 32 for an auxiliary feeding device I8.
The ammunition caisson, container, or box itself, shown in the drawings, comprises, among other things, spaced, parallel front and rear plates II, I2, united by means of cross-ties I3, and a flexible belly band I4, formed of a relatively thin strip of steel attached at each end to one of the ties I3 and guided and restrained, in the form of a G, around the open periphery of the box, by the other ties, I3.
' It also includes a track I6, I1, having a center line indicated as :1J- x, formed about two separate axes of curvature C, CI within said box, and contains and guides a belt, I5 of cartridges, the links of said belt not being shown. This track comprises two opposed parts: a relatively narrow and deep, spiral, channel I6, formed on the inner face of the front plate Il; and a relatively wide and shallow, spiral, channel I1, formed on the inner face of the rear plate I2. The channel I6, guides the points of the shells I5, the channel I1 guides the bases thereof, and the belly band I4 guides the links (not shown) around the periphery of the box and prevents accidental uncoupling of said links.
The ends of the belly band I4 are anchored to the box respectively above and below the beginning of the track I6, I1, so as toform therewith, a feed mouth opposite an auxiliary feeding device I8 mounted on the cannon (not shown),
which is fed by means of thebelt I5. The lower L or inner of said ends of the belly band I4 is folded around one of the cross-ties I3 so as to form a substantially horizontal projection I9, which acts as a bridge or chute operatively to connect the box to said device I8.
The arrangements above of the track I6, l1 within the box provides such a balancing of the weight of the shells I5 that there is no excessive load placed upon the feed mechanism on the cannon in drawing said shells into said cannon, ex-
cept at the beginning of the feeding operation, which resistance is due principally to the relatively high frictional strain or force opposing the advance of the belt around the inner parts of the track where the radius of curvature of the track about the axes C, CI is at the minimum. To meet and overcome this condition, a pair of power-sources or boosting devices is mounted along the axes C, CI. Each of said devices cornprises a shaft 2U, pivotally mounted across the box in ball bearings 2I; a pair of sprocket wheels 22, fastened on said shaft 20 and projecting within the path of the shells I5; and a spring motor 23, mounted anterior to the plate I I on a sleeve 24, coaxial with either C or CI, as desired, and screwed into said plate II. Each spring motor in turn comprises a barrel '25 freely mounted on the corresponding shaft 20; a spiral spring 26 anchored at one end to said sleeve 24 and at its other end, to said barrel; a pair of pawls 21, pivotally mounted on the front of said barrel; and a ratchet wheel 28, fastened on the shaft 2) to receive a crank or handle (not shown).
The arrangement of the said boosting devices with respect to the path of the belt is such that, during the lling of the box, when said motors 23, are wound up by hand, near the end of said filling operation, the boosting eiiect of the devices helps overcome the frictional forces opposing the advance of the belt along the track toward the dead end of said track, where said forces reach a maximum. During handling of the full box, and until the power feed operation starts, the inertia of the belt I5 prevents premature dissipation of the energy stored up in the motors 23 by said hand-winding operation. At the beginning of the power feed operation, the positive pull applied by the cannon upon the belt is automatically augmented and boosted by said motors 23, which then drive the inner end of the belt i5 in the opposite direction, through the sprocket wheels 22. If desired, due to the ratchet coupling- device 21, 28, the springs 25 may be wound counter-clockwise over more than the one or two turns it takes to bring the l0 first shells of the belt Iii into the position shown in Figure 3, without affecting the shafts 2lii. e., without affecting the position of the belt-by simply rotating the barrels 25 by hand-also in the counterclockwise direction-until the resistance of the springs '23 becomes excessive.
By virtue of the foregoing structures and arrangements, the capacity of this general type of ammunition container is increased manifold times; for instance, the capacity of the containers forthe largish, rather heavy 37 mm. rounds or cartridges for an automatic 37 mm. aircraft cannon-a true piece of ordnanceis increased by an additional 300%; or, from 15 rounds to 50 rounds. It also renders the larger number of shells easier to handle and reduces the number of operators required. from two. to one.
It is contemplated that the box II, I2, I4 be inserted from below into the well 3U; and it is also contemplated that it be provided with a three-point suspension system, which cooperates with said fittings 35, 31 and said hooks 36 to hold the box securely, but detachably, within said well. This suspension system comprises: an aligned pair of Lipper shoulders 4I on the plates II, I2, cooperating with the upper fittings 35 to hold the box down in the well; and two transverse lower support shafts 42, 43, projecting on each side of the box and cooperating with the hooks 36 and with the open sleeves 31, respectively, to hold the box up, securely but detachably, within the well. The support shaft 42 is xed across the box l l, i2, I4 and forms a trunnion 44, which can be engaged over the hooks 35 to hold the full ammunition box in the wing by one of its lower edges. Between the barrels 25, through a pair of sleeves 45 xed on the front plate II (and through corresponding sleeves, fixed on the back plate I2), there may be temporarily inserted an auxiliary, U-shaped handle 46, when it is desired to swing the iilled box (now freely hanging from the hooks 36), about said hooks, acting then as hinges, into its operative position shown in Figures 1 and 3. This arrangement further aids in reducing the number of operators required, from two torone. The support shaft 43, on the other hand, is pivotally mounted in the box II, I2 and projects on both sides thereof so as to form aipair-of grooved latchingebolts 4:1; whichcoe.
