The gear 0 engages Upon some convenient part of the frame the gear 1) within the-conical box before menwhich supports the stacker, preferably near tioned, which serves to protect said gears. the center, is mounted a gear-stgment, A, A shaft, F, is movably mounted in bearings which is provided with gear-teeth on its pcff, attached to some convenient portion of 45 riphery. I prefer to provide the frame with the frame, and is provided with pinionsf a hollow cone-shaped box having a projectirg and a worm, f adapted to engage the teeth flange or collar on its upper face, and mount of the segment A. A counter-shaft, G, is the segment A above said box in such a manmounted upon some part of the frame, havner that it will rotate freely. This segment ing one end provided withapinion, 5 Below 5 is n'ovided with aclampcomposed oltwoparts, the sha lt G, and preferably upon the outside I00 of the frame of the stacker, is a plate, II, which may be of any desired shape, and is pivoted to the frame, preferably at the point where shaft E passes through it. This plate is provided with two studs or journals attached thereto in any desired manner, and provided with pinions 7L and 7t, engaging each other, the ends of said studs being preferably connected by means of a plate, 71 or other strengthening device.

YVhen the plate H is in its normal position, as shown in Fig. 1, the pinions 7 2. and h are engaged by pinion g and a gear, 6 on the drivin -shaft E, respectively. By giving the plate H a slight movement upon its pivot, so as to lower pinion h out of engagement with pinion g, the gear hf will revolve about the gear 6 and engage with the pinion g, thus imparting a reverse motion to pinion g. The worm g on shaft G will impart motion to the shaft 1*, which will actuate the segment A through the worm f and by moving the plate H in one direction or another the motion of the pinion g and the segment A may be reversed at will.

I may provide a stop, J, on a convenient portion of the frame, adapted to be engaged by a projection, J, secured to the plate H, for limiting the downward movement of said plate. In order to effect this oscillating move ment automatically, and to limit the movement of the segment in one direction before reversing, I provide a lever, I, one end of which is pivoted to the main frame, while the other is heavily weighted. This lever is provided with a stud, i, which is connected by means of a link, 2' to the upper part of the plate H, and a rod, 2", is suitably attached, as shown, to the lever Lhaving its free end provided with a projection adapted to engage studs 011 the segment A. I preferably provide the segment A with a series of apertures, a, at each end of its toothed portion, one aperture of each series being provided with a pin or stud, a hen the segment has rotated in one direction a certain distance, the stud (o will engage the projection on rod 2 and force the lever I to swing toward its pivot. \Vhen the lever I has been moved past a perpendicular position, the weighted end of the lever will tend to fall, and thereby actuate the plate H and hold it in position until the mechanism is again reversed.

By placing the studs a in different apertures the distance which the segment and carrier will rotate in one direction before reversing their movement may be regulated. I prefer to provide the link with a slot engaging the stud 't', so that as the lever I is moved into a perpendicular position the stud will move easily in the slot. hen the lever has passed the perpendicular, its upper weighted end will fall and the stud a", striking against the end of the slot, will actuate the plate II, as before described.

I may prefer to mount the shaft F so that it will'be capableof longitudinal movement in its bearings, and to provide the shaft with a collar, f secured thereto by means of a set-screw or other preferred means for limiting the movement of the shaft in one direction. The gear f will limit the movement in the opposite direction, and the collar f may be set at different points to regulate the longitudinal movement of the shaft. By this means, when the lever I has been thrown over and the direction of shaft G reversed, the first revolutions of the worm f will move the shaft F longitudinally in its bearings and permit the segment A and the carrier to remain stationary. When the shaft I has moved sufficiently to allow the collar f or pinionsv f to engage one of the bearings, the shaft will be held from further longitudinal movement and the segment and carrier will be rotated by the worm. As the shaft I is moved, the worm g will engage the gears f successively; or I may employ one wide gear, if preferred, so that motion will be imparted to shaft F continuously. By allowing the shaft F a slight longitudinal movement the segment and carrier are given a period of rest at the end of their movement in either direction before reversing. If it is desired, the collar f may be released and the shaft F allowed to move longitudinally until the Worm f is out of engagement with segment A, when the carrier may be moved by hand to any position desired.

The carrier is constructed in the usual or any preferred manner, and preferably con sists of two parts, K and L, which are connected together in any desired way. I prefer to construct the part L slightly narrower than the part K, and secure the parts together by means of bolts or pivots 7t 70, which pass through the sides of the carrier, as shown in Fig. 10. The part K is also provided on the under side with a cross-piece, lc', at some distance beyond the point of pivoting, which forms a support for the part L of the carrier when in its operative position. These pivots or bolts enable the part L to be folded within part K for convenience in transporting and when not in use. The front end of the part K of the carrier is connected to the cross-bar C of the carrier-frame by a sector-frame consisting of standards M, which are pivotally secured to said cross-bar and also to the carrier.

A shaft, N, is supported upon the cross-bar C, and has its inner extremity provided with a bevel-gear, n, to engage the gear I) on shaft 13. The outer extremity is provided with a sprocket-wheel, n. The front end of the car-' rier K is provided with a shaft over which the endless apron travels, and its outer extremity is provided with a sprocket-wheel, 'm, which receives motion from a similar wheel, or, on shaft N. In order that these sprocket-wheels may be maintained the same distance apart in all positions of the carrier, it is desirable that the points at which the standards M are pivoted to the cross-bar and to the carrier should coincide with the shafts of said wheels.

To this end I provide the said standards with bearings in, through which the shafts of the sprocket-wheels may pass. Each of these hearings is provided with a flange by which it is attached to the standard, and it preferably extends a short distance past the inside face of the standard, and forms apivot to engage the carrier, as shown in Fig. 8. By this means the shafts are relieved of strain in raising and lowering the carrier and supporting it in position.

The lower ends of the standards M of the sector-frame are provided with segments 0 O, havin gear-teeth adapted to be engaged by pinions p on a shaft, P, which is suitably mounted in bearings on cross-bar C. One or both ends of said shaft are provided with ratchets p, adapted to be engaged by pawls 19 attached. to the segn'ients O O. This construction enables the standards )1 to be raised or lowered and held in any desired position, thereby controlling the lower end of the carrier. Power may be applied to shaft P by means of a crank, as shown in Figs. 4: and 5, or in any other preferred manner.

The shaft N, which imparts motion to the endless apron, may extend entirely across the carrier and be provided with a sprocketavheel, of, on the side opposite or, connected by means of a chain with a wheel, on, on the shaft which carries the wheel 417, if desired, or the shaft may extend only from the center of the crossbar to one side.

A rigid brace-frame supports the discharge end of the carrier at a point near the center of same. This frame consists of standards R R and V V, extending at an angle to each other and joined. in any suitable manner. One end of. this frame is rigidly attached to the segment A, and the frame is suitably braced by rods or braces r 'r, extending from the cross-bar (I. Two nearly-vertical arms or standards, R R, extend from the upper part of this frame, and have their upper extremi ties provided with pulleys r r. The standards M may be provided with similar pulleys, m forward of their pivots, and a drum or shaft, S, is suitably mounted on some part of the brace-frame and provided with any convenient actuating means.

A cord or chain is connected with the carrier at some point on each side of the part L, and these cords or chains pass over the pulleys r, thence to the pulleys on standards M or cross-bar C, and thence back to the drum S. In the drawings the cord only is shown; but it is obvious that a chain might be em ployed for the same purpose. It will be seen that by revolving the drum S to wind or unwind the cord or chain the carrier may be raised and lowered at will. The arms or standards R are held in position by staples r, or similar devices, and may be removed from e11- gagement with the rigid frame, if desired. \Vhen the carrier is folded for transportation, the arms R are preferably removed and. the carrier allowed to rest upon the horizontal brace It. When the carrier is in this position, I may employ braces T, mounted upon some part of the main frame, as shown in Fig. 3, to relieve the brace-frame from strain. hen the carrier is in use, these braces drop down out of the path of the brace-frame. liy means of this brace-frame the weight of the carrier is supported near the center and at one end of the same, and in raising the sector-frame the part L of the carrier, by its weight, assists materially and renders the operation of elevating that end of the carrier easy. I may provide the drum with suitable means for retaining it in any desired position. I may prefer to provide the part L of the carrier with a cross-bar, .9, extending below the same and havin its extremities provided with pulleys s The cord or chain may then be continuous from one side of the drum, through the pulleys s, r, and 721 to the other side, and by this means the carrier may adjust itself with its side portions the same distance above the ground.

The operation of my improved stacker is as followsnThe part l) of the carrier is unfolded and the carrier elevated into the desired position by means of the drum or windlass S. The rear end of the carrieris also adjusted to receive the material by rotating the shaft P. Power is then applied to the band-wheel c from any convenient source and motion imparted to the central shaft, B, and to the endless apron of the carrier. Motion will at the same time be given to the pinion g and to the shaft F and worm f thereby causing the segment A and the carrier, to which it is attached by means of the sleeve B, to move with said sleeve as a center. hen the carrier has moved a certain distance, the pin a" will enage the projection on red i and throw the lever l in a direction toward its pivot, thereby movin the plate U and reversing the direction of the shaft F, as before described. The first revolutions of the worm f will move the shaft F longitudinally and permit the carrier to remain stationary until the longitudinal motion of said shaft is arrested, when the segment and carrier will be rotated in the op posite direction.

If desired, the collar f on shaft: F may be secured to said shaft at a point adjacent to the bearing f, which is engaged by gear f, when no lost motion will be allowed the seg ment and carrier upon reversing the motion of the worm f As before stated, the worm f may be entirely disengaged from the segment A, and the carrier oscillated by hand, or allowed to remain stationary, as desired.

The material will be deposited upon the lower portion of part K of the carrier and will be elevated and discharged from the top of the carrier. The oscillating motion of the carrier will deposit the material in even 1ayers. \Yhen notin use and for transportation, the stacker maybe folded very compaetlyand will occupy little space.

I do not desire to. be limited to my exact ITO constructions, as variations may be made' therefrom without departing from the spirit of my invention.
