SPECIFICATION forming part of Letters Patent No.v 422,102, dated February 25, 1890.

Application filed October 16, 1389. Serial No. 327,211. (No model.)

To all whom t 11i/ay concern:

Be it known that we, ANDREW H. WEHRLI and FRANK J. SANCHEZ, both citizens of the United States, residing in VMonee, county of lVill, State of Illinois, have invented certain new and useful Improvements in Grain- Dumps, of which the following is a specification.

This invention relates to improvements in grain-dumps employed in connection with grain-elevators. and car-loading and similar apparatus in which the grain is dumped from a wagon into the hopper of a grain-elevator or directly into a car being loaded, and has for its prime object to avoid the necessity for turning the wag'on upon an elevated platform, either by teams or by hand, as has heretofore been necessary in order to bring the tail thereof in proper position for dumping, and to reduce the labor necessary for and materially facilitate the operation of dumping' or discharging the grain from the wagon.

Another object is to have the-d umping-platform horizontally rotatableand vertically adjustable in such manner that it will assume an inclined position automatically and simultaneously with the turning or partial rotation thereof, wherebya wagon or other vehicle upon the platform will be inclined and the contents thereof discharged simultaneously with the turning of the wagon in position for dumping. i

A further object is to have 'the rotatable and automatically-inclining dumping-platform supported in such inannerthat the platform may be returned to a horizontal position from its inclined position without further rotation in either the saine or the reverse direction, whereby the wagon or other vehicle may be drawn off the platform in a line at a right angle from that in which it was drawn on the platform.

These objects'are attained by the devices illustrated in the accompanying drawings, in which- Figure l represents a perspective View of a car-dumping platform and runways leading thereto, illustrating the use of our invention; Fig. 2, a side elevation of the dumpingplatform, showing the same in its normal horizontal position; Fie. 3, a transverse vertical section thereof at a right angle to Fig. 2; Fig.

4, a plan view thereof with the platform removed, but showing the operating mechanism thereof; Fig. 5, a transverse vertical section taken on a line at right angles to Fig. 3, showing the platform inclined and means for returning it t-o a horizontal from its inclined 'position without the necessity for rotating the same; and Figs. b and 7, plan and side elevations, respectively, of a modified form of rails for supporting the dumping-platform. Similar letters of reference indicate the saine parts in the several figures of the drawings.

Referring by letter to the accompanying drawings, A indicates the frame for supporting the dumping-platform B, which latter is circular in form and pivotally supported upon a horizontal axle C, underlying the platform across the center thereof, and projecting be yond the same, upon the ends of which axle are looselymounteda pair of carrying-wheels D, running upon. horizontal rails E, rigidly secured to the frame A, and curved on the arc of a circle struck from the axis ofthe platform, preferably extending a quarter of the circumference thereof at the opposite sides of the platform, so that the platform may make' a quarter-turn while supported upon these rails.

' Pivotally secured to the edges of the platform, at each side thereof, midway between the ends of the axle, are a pair of depending trucks F, having wheels G journaled therein and running upon' a pair of curved inclined rails II I, secured to the frame A, and `extending a quarter about but below the platform on the opposite quarters occupied by the horizontal rails, one of which II inclines upwardly, while the other I inclines downwardly from the same horizontal plane, both inclining at the same angle, so that as the platform is turned and supported atits center on the radial lines of the axle one of the trucks will run down the inclined rail and the other up the corresponding inclined rail, causing the platform to tilt or swing upon the axle as a pivot, it being understood that the center of the platform remains at all times in substantially the same horizontal plane, being supported and so held by the horizontal tracks. Thus when in its normal horizontal position all of the four carrying-wheels will be at one IOO end of their tracks, but that when the platway L, after which, if desired, the team maybe unhitched and led off of the elevated platform J down the runway L. The tongue of the wagon may then be employed as alever for giving a quarter-turn to the du mpin g-platform, which, as before described, assumes an inclined position simultaneously with the turning thereof,

s that when the quarter-turn is complete the body of the wagon will be sufficiently in-` clined to discharge the grain therefrom by gravity when the tail-gate is removed, the grain being either dumped into the hopper of a grain-elevator or directly into a car N upon a track laid along the side of the platform. If desired, however, the team may be employed for turning the wagon and dumping-platform. After the load is dumped the platform may be turned back a quarter, when it again resumes its norlnal horizontal position, and the wagon may be drawn off the platform and down the runway L. In practice, however, we have found that it is not always practicable or convenient to have the runway L, but that the runway M must be employed instead thereof, and in order to avoid the building of a large elevated platform, and which, too, may be equally impracticable, in order to allow the turning of the wagon upon the platform after being drawn off the dumping-platform, we have illustrated in Fig. 5 means for returning the dumpingplatform to its normal horizontal position without having to turn the same backwardthat is to say, wit-hout having to give it a reverse quarter rotation. Thus after the wagon has-been drawn up the runway K and turnedupon the turn-table at right angles to said runway, as illustrated in Fig. l, after the grain is discharged therefrom the wagon will simply be shiftedto a horizontal position without turning, and facing the runway M, down which it may then be drawn. To

accomplish this end, we employ alever O,-

pivoted'centrally of its length to a crossframe beneath the center of the dumpingplatform, having vertical extending links P Q, pivotally connected therewith near each end, to the upper ends of which links are pivotally connected and thereby supported the lower end of the inclined rail Il and the upper end of the inclined rail I, so that when the lever is swung upon its pivot, after the dumping-platform is tilted to the inclined position shown in Fig. 5, the two rails will be swung to substantially a horizontal position, thereby lowering the elevated side of the platform and raising the depressed side thereof upon the axle as a pivot, thus restoring the platform to a horizontal position without turning the same. Of course, after the wagon is drawn off the dumping-platform, it will be turned back a quarter-turn and the lever operated, so as to restore the partsv to their normal position.

The lever O may be operated in any wellknown and convenient manner, one form of which is illustrated in Fig. 5, consisting of a connecting-rod R, pivotally secured at one rend to the lever O and at its opposite end to a bell-crank lever S, pivoted upon a suitable bracket attached to the main frame A, and provided with a hole T, adapted and arranged to register with corresponding holes U, formed in a segment V, secured to the bracket, so that by means of a Vlock-pin passed through the holes in the bracket and lever the parts may be locked in their adjusted position. This actuating apparatus, however, mayl vary materially from the construction shown, for instead of' the hand-operating bell-crank lever S a foot-lever or any other means may be employed for operating the lever O, so long as the'. desired result is accomplished.

In practice we prefer to furnish an additional support for the dumping-platform to relieve theaxle thereof of a portion of the weight of the load by means'of an upright post XV, rigidly secured. at its lower end to a stationary portion of the frame A, and with its upper end formed in a ball X, working in a suitable socket provided in a plate Y, secured to the under side of the dumping-platform at the center thereof, constituting a balland-socket joint, which, while it supports the center of the platform against vertical movement, at the same time'permits the free rotation and tilting of the platform.

Vith the construction illustrated and described it will be understood that the wagon must always be drawn upon. the dumpingplatform over either the runway K or L, because the platform always turns in the same direction, and the wagon must face correspondingly, in order that the discharge end thereof may be presented to the hopper, car, or other storing-receptacle; but, if desired to vhave the dumping-platform so operated that the wagon may be drawn onto it from either direction and dumped by the turning of the platform either way, it is only necessary to have all of the tracks circular, as illustrated in Figs. 6 and 7, with the opposite corresponding quarter of each inclined track inclined in the same direction, but in different planes, with the two intermediate quarters reversely inclined-that is to say, inclined in opposite directions to each other-so as'to form a continuous circular track, two quarters of which incline downwardly and two upwardly on IOO IIO

IZO

each side of the center or point of conjunction on opposite sides of the circle. This latter arrangement willbe found not only preferable, but necessary at certain points where only a single runway can be employed, because of the proximity of warehouses, carsheds, lumber-yards, time., along the railroad- `track permitting the use of a single runway only; but withthis last-described construction the wagon may be drawn on the dumpingplatform from either direction in which it is convenient to extend theV runway, given a quarter-turn, so as to dump its load, and then given another quarter-turn in the same direction, thus restoring the platform to a level, with the wagon now facing the runway up which it was drawn to theplatform.

From the foregoing description it will be understood that we are enabled to employ lour invention in three different forms, to wit:

in the form shown in Figs. 2, 3, and et, in which the inclined rails are stationary and the runways K and L are required, or in the form shown in Fig. 5, in which the inclined tracks are vertically movable at oneend and the runways K or L and M are required, or

in the form shown in Figs. G and 7 in which the inclined track or rail is continuous and only one runway, either K or L, is required. Thus we are enabled to adapt our invention to almost any` conditions or circumstances which may arise, butin all eases embracing the broad feature of our invention-that is,

4the dumping or inclining of the platform simultaneously with the rotation thereof.

Having described our invention, what we claim, and desire to secure by Letters Patent, 1s-

l. In a grain-dump, the combination, with a horizontally-rotatable dumping platform, of horizontal and inclined ends supporting the same, for causing said platform to assume an inclined position simultaneously with the rotation thereof, substantially as described.
