4 5 place. The lever g can be depressed by hand As the shell contained in the tube F is carso as to release the carrier whenever it is deried out of this tube to the first station, S, Fig. sirable. In the circumference of the carrier 3, its rim acts upon a lever, n, which is firmly are a series of semicircular recesses, 71, which mounted on a vertical spindle, 0. This lever correspond in number and position to the acts on the powder-container J, so that the op- 5 number and position of the propelling-cavieration of the machine will cause the desired roo quantity of powder to be deposited in the shell when itis at that station. The shot is deposited into the shellin asimilar manner at another station; but these do not form any part of my present invention.

As the shell is being carried from the first to the second station its rim acts upon the lever O, which is mounted upon a vertical spindle, 0. This spindle has its bearing below in a socket in the platform B and above in an arm, 1?, which extends from the hub I, Figs. 1 and 3. On the spindle 0, near its upper end, is firmly mounted a lever, 0 with a curved slot, 0 ,which engages with a pin, 0, Figs. 3 and 4. This pin projects from a carriage, p, which moves in a radial slot in the arm P,and which carries the wad-pusher 12 To facilitate the proper adjustment of the levers O and 0", both of which are firmly secured to the vertical spindle 0, this spindle is made in two sections, at and m, Fig. 9, which are connected to each other by a sleeve, m which carries a set-screw, ou By this means I am enabled to adjust the relative position of the levers O and 0" with case, either when first assembling the parts or when they have been worn from use.

The wad-container Q consists of a series of vertical rods, or ofa tube, and it is provided with a gate, q, which can be adjusted so that the lowest wad in the wad-container can be pushed out by. the pusher 19. As the rim of the shell passes the lever O the pusher p is forced inward by the slotted lever 0, and the lowest wad is carried over the shell, where it is retained by two spring-jaws, 9 Fig. 2; The pusher p is immediately drawn back by the action of the rim of the shell upon the nose 0 of the lever 0, Fig. 3, whereby the spindle 0 is turned back to its normal position. The shell has now reached station S, right beneath the wad, and the wad is driven down into the shell by the rammer R.

As it is desirable that the wad-container Q, which, as above described, may either consist of a tube or a series of vertical rods, should contain as large a number of wads as possible, it is made of the greatest possible length which the practical construction of the machine will permit, and which is approximately indicated in Fig. 1 of the drawings; but the length of the wad-container there shown will hold only comparatively few wadssay one hundredand would have to be refilled continuously by the operator. To obviate this constant filling by the operator, I employ removable wad-feeding tubes K, Figs. 1 and 6, which contain a large number of wads. These tubes may be filled either directly at the wad-cutting machine or by a much cheaper grade of labor than that employed to run my machines, permitting one operator to run three cartridgeloading machines with ease, where one such machine formerly demanded his whole time. These wad-feedin g tubes may be perfect tubes with an opening at or near the lower end, or they may have a slit running their whole length, so as to permit the operatorto notice the number of wads in the tube at any time and to remove the tubes when the wads therein have reached a point when it is necessary to insert a full feed-tube. To insure the downward passage of the wads in these tubes, I employ a weight, 0, which will keep them in proper position and prevent the clogging of the tube.

By the subsequent movements of the carrier D the shell is moved successively to the stations S S in each of which it receives an ad-. ditional wad. Then it is moved to the station 8*, in which it receives the shot, which'is introduced into the shell from the shot-container J precisely in the same manner in which the powder is introduced from the powdercontainer J. After the shell has been charged with shot it is moved by the carrier to the station S in which it receives a wad, and then it is moved to station S in which it is crimped. This operation consists in turning over the upper edge of the shell after it has been loaded, as seen in Fig. 8, and is effected by means of the rotary crimper T, the form of which is shown in Figs. 7 and S. This crimper consists of a thimble, p, in the un der surface of which is formed an annular groove, q, the bottom of which is rounded. Into this thimble are inserted the crimpingpins 9, into each of which is cut a groove, 1). These pins extend into the annular groove q in such a way that while the grooves p in the pins register with the annular groove {1 the bottom of 'each groove 1) in the pin is situated in a different plane from the bottom of the annular groove in the thimble, thereby forming concave projections, Fig. 8, which act on the edge of the shell and turn the same down, while the sides of this annular groove embrace the shell and prevent its distortion during the crimping operation. It is evident that the same result might be obtained by forming the concave projectionsp directly on the bottom of the annular groove in the thimble. The difficulty of construction of such a form of crimper is obvious, while by means of the crimpingpins the concave projections p can be produced without difficulty. These radial crimping pins are adj ustably fitted in the thimble, so that they can be rotated axially in their seats for the purpose of bringing new or fresh portions of their annular grooves into position for crimping when such grooves become worn in one place. The pins are also readily removable, so that they can be replaced by new ones, when desired, at small expense.

In the example shown in the drawings, Fig. 1, the crimper is secured to aspindle, t, which slides loosely through a bearing, t, in an arm, U, extending from the hub I, and also through the cross-head N, and is provided with an adjustable collar, 1?. At its upper end is formed a conical teat, which fits a socket in the vertical shaft t", which has a sliding bearing in the journal-box M, and which carries the pulley IIO it, connected by a belt with a countershaft, as shown in Fig. 1, from which the required rotary motion is imparted to the shaft t and to the spindle t carrying the crimper T. In addition to a rotary motion, the crimper must also have a rising and falling motion, so as to release the shell after it'has been crimped. This is accomplished by the cross-head N, to which a rising and falling motion is imparted from the main shaft E. In this cross-head is formed the bearing 15* for the spindle t, and in the example shown in the drawings, it consists of a bushing held in position by a nut. When the crosshead is down, the crimper will rest on the shell by the weight of the parts to which it is connected, in which position it will remain until it has performed its function, when its further downward motion will be arrested by either or both of the collars t i As the cross-head rises it will strike the collar t on the spindle t, and carry the spindle and the parts connected to it upward and out of action until a new shell shall have come under the crimper, when it again descends, thereby permitting the crimper to act on said new shell. To prevent noise and to take h shock f h r s d against the collar ii a Coiled sp g, lSplaced between these parts.

'1 am aware that a shell-crimper has been heretofore composed of a cup-shaped bit having a circular groove in its base and provided with radial pins extended across said groove, slightly raised, and having inclined grooves across their upper sides to assist in turning the edges of the shells inward, Such, therefore, I do not claim.

Vhat I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a cartridge-loading machine, of the upright column A, the plat form B thereupon, the shell-carrier D, resting on the platform, and means for intermittently rotating said carrier, with the vertical rotating shaft carrying a shell-crimper, T, at one end, and an automatically rising and falling cross head, N, having a bearing, t", through which the crimper-carrying shaft passes, substantially as described.

2. The combination, in a cartridge-loading machine, of the upright column A, the platform B thereupon, the shell-carrier D, the main shaft E, connections between the main shaft and the carrier for rotating the latter, the vertical rotating shaft carrying a shell-crimper, T, and a cross-head, N, connected w th the crimper-carrying shaft and raised and lowered by the main shaft, substantially as described.
