To all whom it may concern.-
Be it known that We,-GEORGE W. L. SMITH and JOSEPH F. DRESBAOH, citizens of the- United States, and residents of Homer, in the county of Ohampaign and State of Illinois, have invented certain new and useful Improvements iirPortable Dumping Apparatus; and We do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
Figure 1 of the drawings is a representation ofthis invention, and is a top view. Fig. 2 is a vertical section. section. Fig. 4 is a view of the bed-frame. Fig. 5 is a horizontal section.
Our invention relates to a portable dumping apparatus for emptying grain, &c., from loaded wagons into bins or cars; and it consists in the construction and novel combination of parts, as hereinafter described and claimed.
Referring by letter to the accompanying drawings, A designates a portable bed-frame which is rectangular in form, and is provided with a longitudinal'mid'dle sill, B, which is providedat its middle portion with a vertical spindle, O. The side sills, D and E, of the bed-frame are provided with recesses F at about their middle points. In the said recesses F are journaled friction-rolls G. The middle sill, B, is provided near each end with 'an/elongated friction-roll, H. The frictionrolls H H are journaled in recesses I of the middle sill.
The base of the revolving frame J corresponds, so far as its main timbers are con cerned, with the bed-frame A; but it is provided on its under face with a circular table, K, which travels on the friction rolls G H when the frame is revolved. The base of the frame is also provided with a floor, L, which is laid between the side timbers, end timbers, and the middle sill of said frame,'and is flush with the upper face of the said base.
The spindle G is provided near its upper Fig. 3 is a verticalinserted to hold the revolving frame in place while it is being turned thereon to adjust it to the place at which it is to be used.
N is the operating-shaft, which is preferably rcctangular in crosssection, and isjournaled in bearings I? P, either upon the end girders of the frame, as in Fig. 1, or in bearings P P, depending from the lower faces of said girders, as in Fig. 3.
S is a centrally'located pulleysecured to the shaft N, towhich the draw-rope T is secured. The draw-rope T is wound upon the pulley S when the suspensiontrack U is in the low-' ered position, and said rope T runs down over a pulley, Y, journaled in bearings IV, secured to the top rail, X, of the revolving frame and passes under a pulley, Z, supported in a block connected by links to the base of the revolving frame. The lower end of the rope T is provided with a clevis-block, a, to which the double-trees are connected and to these latter the team is hitched when it is desired to operate the dumping apparatus.
On each side of the pulley S, and at proper distances therefrom, the shaft N is provided with pulleys c and d, which are connected by ropes e f to the track U. The ropes ef run over'pulleys g h, journaled in pulley-blocksi j, secured to the upper portion of the revolving frame, and thence over pulleys it (there being but one shown) on journals projecting inwardly from the opposing faces of the uprights m n of the said frame.
Immediately at the outer sides of the pulleys c and d the shaftN is provided with two pulleys, p g, which are connected by suspension-ropes 1- s to the rear end of the suspension-track U, said ropes r .9 running over pulleys ta, journaled on bearings projecting inwardly from the opposing faces of the uprights o w of the revolving frame J.

The shaft N is provided just outside of its bearings with ratchet-wheels a0 3 which are engaged by pivoted detents l 2, secured to the revolving frame and connected near their upper end by a transverse bar, 3, journaled in bar 3, and is shouldered at its front end, said shouldered end resting in a slot, 5, in a vertical arm, 6, projecting from the top of the re volving frame at the front end thereof. \Vhen it is desired to hold the detents out of engagement with the ratchet-wheels x y to permit the descent of the track U, the arm 4 is pushed back until the shoulder drops and engages the rear face of the vertical arm (3.
Immediately outside of the ratchet-wheels w y the shaft N is provided with the fixed pulleys 7 and S, which pulleys are provided with weighted cords 9 10, which operate to counterbalance the weight of the descending wagon on the suspension-track after the contents of the wagon have been dumped into the bin or car, as the case may be. At each end the shaft N is provided with a brake-wheel, 12. Brakelevers 13 and 14 are fulcrumed upon the revolving frame and project out in front of the brake-wheels 12 1'). These brake-levers are connected at their inner ends to each other and to a locking lever, 15, by a vertical pin, 16, passed through aligned holes in said brakelevers and locking-lever. The locking-lever 15 is provided with a hookshoulder, Z, at its front end, which engages the vertical arm 6 when it is desired to apply the brake-levers to the brake-wheels to control the descent of the emptied wagon on the suspension-track U.
The ropes cf, which connect the pulleys 0 (Z with the track U, are secured to the peripheries of said pulleys c (I about fifteen degrees below their horizontal diametrieal lines when said pulleys are in their normal positions that is, when the track rests on its platformso that the ropes of do not commence to lift their end of the track as soon as the ropes 1' 8 do, the latter ropes being connected to the pulleysj) g at distances of ninety degrees from the points where the ropes e f are connected. By this arrangement of the ropes the rear end of the suspended track will commence to rise before the front end of said track, so that the proper inclination to insure the dumping of the contents of the wagon-bed will be given. The front cross-bar, 17, of the track U is pro vided with friction-rolls 1S and 19, which travel up and down the two uprights of the revolving frame, with which they come in contact and thereby lessen the friction and render the apparatus easier to operate than it would otherwise be.
In order to move the machine about the farm or along the railroad-track, we provide a suitable wagon or running-gear, upon which we mount the machine and draw it to where we desire to use it. The apparatus is therefore portable, and may be used where it may be found useful.
Having described this invention, what we claim, and desire to secure by Letters Patent, 13-- 1. The combination, with the bed-fra1neprovided with the spindle and friction-rolls and the revolving frame, of the transverse operating shaft provided with the central pulley, the pulleys a (Z k and 7 8, the weighted cords and ratchet-wheels, the pivoted connected detents, the shouldered arm 4 and slotted arm'6, the suspended track, and the draw-rope, substantia'ly as specified.
2. The combination, with the bed-frame provided with the spindle and friction-rolls and the revolving frame, of the transverse operating-shaft provided with the central pulley, the pulleys 0 (Z k and 7 S, the weighted cords and ratchet-wheels, the pivoted connected detents, the shouldered arm 4, vertical arm 6, the pivoted brakes, the locking-lever, the suspended track, and the draw rope, substantially as specified.
3. The combination, with thel'Jed-frame and the revolving frame, of the hinged bridge and the supporting-spring, substantially as specified.
In testimony whereof we LffiX our signatures in presence of two witnesses.
