The improved orienting mechanism of this in;-

vention is shown applied to a -cartridge loading machine which handles both ball cartridges and tracer cartridges. substantially the same physical characteristics; shape, weight, positionof center of gravity; etcr,

as the ball cartridges. It is standard practice to load-the cartridges in the belt or carrierso that every-fifth cartridge is a'tracer; this is followed inthe machine hereillustrated. The tracer ear tridges'are heaped into a single large hopper 40 which is provided "with a centrally located iii-- verted-V divider 2| (Figs; 1 and 3) which directs the tracer cartridges 'to two arteries- 22 and-"22 (Fig; 1). The ballcartridgesare heaped into-aplurality,--four as shown "in the figures (especially Fig.1), of small hoppers l0. Each-hopperis= divided'into two arteries l2. There being :four hoppers l0 and each hopper- I0 having-two arteries 12; there are in all eight ball 'cartridge'ar--- teries l2; and also, as described-above, two tracercartridge arteries -22.- As clearly seenin-Figxl; the lowermost artery'shown onthe sheet is tracer The tracer cartridges .1 have artery 22', which is followed by-four ballarter-ies=- l2, and, next, by the second tracer artery";

held to rotor I40 by machine bolts 5, which are similar to bolts 4 in that they are of the long type, to pass through holes l5 provided in end rotor I40. End rotor [4c is adjustably held to rotor Md by shorter bolts 3.

The seven rotors thus far described (namely, rotors 24a, 24b and Ida, b, c, d, e) constitute onehalf of the rotor assembly, more particularly, the right half as viewed in Fig. 4. The other or left half is precisely the same, the rotors, bolts and The cartridges, held at the top point of the rotors in a vertical position (as is cartridge N, Fig.2) are removed therefrom and oriented in orderly manner with their primer ends foremost a (as are cartridges Q, Fig. 2) by fingers I (best shown in Fig. 2) which are secured at one end to the right end of chutes 8. The distal ends of the other parts bearing the same reference characters as described above in connection with the right half.

As mentioned above, rotors 24a and 24b cooperate together to orient the tracer cartridges coming down artery 22', Fig. 1. For this purpose the outer edge portion of the facing sides of rotors.

24a, 24b are provided with a beveled ring, respectively 26a and 26b, oppositely pitched or sloped A.

as best seen in Fig. 4. End rotor Ma and inner rotor- Mb cooperate together to'- orient the bail cartridges coming down artery IZA, Fig. 1. For this purpose, the outer edge portion of theleft face (see Fig. 4) of end rotor Ma and the right face of inner rotor Mb, i. e;, the two facing sides of I la, [4b, are provided with oppositely sloped beveled Mia and 161), respectively. Inner rotor Mb, more particularly, its left face in Fig. 4, cooperates with the right face of'inner rotor Mo to orient ball cartridges coming down artery.l2B.

The improved orientingmechanism of this invention is designed to orient cartridges heaped disorderly in a hopper, e.- g.,-in hopper 20, Fig. 2, in an orderly manner, with the primer end of the cartridge foremost (on the chute or slide 8, Fig.

2). To accomplish this the shaft 30 and its rotor assembly is rotated in a counterclockwise sense (as'viewed in Fig. 2). The cartridges slidingdown Fig. 2).

Iclaim: I 1 In a device fori'orienting cartridges with their-primer ends pointed in a predetermined direction, the combination of a hopper into which the cartridges are promiscuously heaped, a chute "leading from the hopper, a shaft, a disc fixedly mounted on the said shaft to rotate therewith,

The cartridge'M in Fig. 2 happens to have its primer end foremost. The bevels of the rotor bear a predetermined relation to the outside diameter of the primer end of the type of cartridgeto be handled by the machine, such that, after the rotors have been adjusted by their adjusting bolts I to 5, the primer end of a cartridge will be frictionally caught between the cooperating bevels of a facing pair of rotors (see cartridge M, Fig.2), as the rotors turn in a counterclockwise sense, Fig. 2,'a

cartridge caught by its primer end (such as the cartridge M), will be carried around by the rotor. The center of gravity of the type of cartridge to be oriented by the improvedmechanism in close to its projectile end, i. e. removed from its primer end lowermost (see cartridge tridge tOftllIll the cartridge to a substantially projectile end foremost, the major portion-of the cartridge will pass between the pair of facing bevels, until the" primer end becomes frictionally Fig. 2 to bring it vertical. precisely like cartridgeN.
