Be it known that I, FRANK C. GRFENE, citizen "of the United States, resident of i 1 Cleveland, countyof- Cuyahoga, and State of Ohio, have invented a new and useful i l i Improvementin Car-Dumping Mechanisms,

of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have i contemplated applying that principle so as to, distinguish it from other inventions.

The present invention relates to car dumping mechanism and particularly designed for usein' connection'ivith the dumping of mine cars smiles are employed in coal mines and the'like. such mechanism is designed with a superposed track system, that is, a system inwhich theloaded car is received on one track, dumped, and then discharged onto another track below such first track. It is unnecessary here to dilate upon the advantages, such as saving of space and the like, to be had by thus arranging the tracks. There have been numerous difliculties, how: ever, encountered in designing a'dumping mechanism that will'work easily and effectively in the situation, thus presented. In a co-pending application, filed August 15, 1906, Serial 7150'. 380,652, I have broadly set forth a tyre of dumping device invented by me whereby' manyiof these difiiculties are The present anemia but another specificform of the invention there generally things, theadaptation of the device to power operationgwherebyat' least certain of the movements may be positively efieeted and controlled, asIal sQ 'tl1e provision of means whereby the car maybe shaken or jarred to facilitate the, dischargeof its contents when in the. dumping position. Incidentally, but

anism, there is show'n acarspotter, that is, a device for controlling; the feeding of the cars onto suchmeclranism. I

To theaccompl ishment of the above and of the means, hereinaftel fully described and particularly pointedoutin the claims.

The, annexed drawings .andthe' following description setforth in detail certain mechanism embodyin'g the invention, such. dis- I closed means constituting, ,howcver, but' one I i H Specification of Letters Patent. Application filed February 1, 1908.

of various mechanical forms in "which the pr nciple of the invention may be used.

in said annexed drawings: Figure l is a' front end elevation of a dumping mechanism wherein the several improvements referred to above have been incorporated, such mechan sm being designed primarily for use in 5 dumping cars of" the kind employed in coal mines of the anthracite region; Fig. 2 is a part section and part side elevation of the same, showing in connection therewith, the car spotter, or feeding device, above referred to, as also contiguous portions of the two superposed tracks with which such dumping mechanism stands in operative relation; in such,Fig. .Z-thedevice is shown in its initial operative position and Figs. 3, 4 and 5 illus trate in similar part section and side elevation successive operative positions of the device wherein the car, received in the position shown in Fig. 2, is dumped and finally ti1scarged onto the lower, or car discharge,

rac

The main operative element of the device is a floating track section A that is sup ported, in a manner presently to be set forth, in a vertically disposed framework B consisting preferably of two plates 1) arranged one on each side of the track section, and provided on their respective inner faces with two guide-ways, B B in which are held rollers or guide-wheels a mounted on the ends -.of transverse shafts a constituting fixed elements in the track-section aforesaid. The guide-ways B B are conveniently formed by securing appropriately bent sec-* tions 6 of angle iron tothe inner faces of the plates 7; and corresponding sets of such .ways' are' respectively adapted to engage the two sets of guide rollers previously referred to. their upper ends and thence curve downward in forwardly, concave fashion with respect to the direction of discharge. In the intersecting portion of the ways there is 10- .cated-a pivotally mounted latch 11 movable to close such .portion against either way. The rearmost way is formed on the arc of a circle having the lower end of the other way as its center, and is furthermore provided with abranch B extending rear; wardly and upwardly 'to a point. just a. trifle above the upper end of such other way. The form of the curve of the foremost we ,B5. is determined by the direction of sho Such guide-waysintersect at r thus position the same alternatel branch B of the rearmost way, and by the' such track-section is designed to be alined with the lower car-discharge track G, the relative elevations of the lower ends of the twoguide ways being determined with this in new.

For the purpose of imparting to the tracksection the necessary vertical movement to in register-with the upper and lower 0 the two su rposed tracks, power means are provi ed. These means in the case in hand consist of a vertically disposed fluid-pressure cylinder -D connected with a suitable source of fluid-pressure supply, preferably steam or compressed air. Assuming steam to be thus employed, the live steam is led from a -supply pipe at through one or the other of p pes d d to the top or bottom end of the cylinder D, the control being had by means of an operating valve. D-located beneath the operators platform D and adapted to be actuated by a suitable handle (i The construction of valve D is such that when one end of the cylinder is connected with thesteam supply pipe 03, the other end isv connected with an exhaust pipe (Z*. I

Associated with power-cylinder I), and alined therewith transversely of track-section A, are two other cylinders D one on each sideof such cylinder D, such cylinders D constituting means independent of said power means for regulating the reciprocation of the track-section. To this end, such cylinders D are filled with a suitable liquid such as dead oil, the flow of which from one end to the other is regulated by a manually operable valve (i in a common pass-pipe 03, thereby regulating the movement of the pistons d reciprocably mounted in the czylinders. The upper ends of such pistons 7 together with the upper end of the piston (Z reciprocable in power cylinder D are jointed.

toa common cross-head I) that is steadied by having its ends provided with rollers d held in vertical guides I) similar to those wherein rollers a are guided. Cross-head D is connected with a transverse shaftA", fixed to track-section A between guide shafts a, by means of connecting rods or links D that are not only thus reciprocable with the pistons as the latter move up and down, but

is adapted-to oscillate with respect to such pistons as the track-section is tilted first in one direction and then the other by the guides B B between which it is held.

In order to retain the car upon thetracksection pending the latters downward tilting movement during the dumping operation, the forward end of such track-section is-provided with a stop, or buffer, (2 consisting simply of the upturned ends of the rails or angle irons, constituting the rails of the section, suitably braced 'to withstand the strain.

In order to minimize the shock that would otherwise be occasioned, both the dumping mechanism and the car, were the latter allowed to bump directly into this fixed stop as it is received onto the track section from theinclined car delivery track C, a resiliently supported secondary stop A is provided wherewith such car has prior engage-f ment. A preferred construction of this secondary stop embodies two dogs a pivotally mounted upon the forward ends of transverse shafts a and so disposed and formed as to 'engage the axle of the car as the wheels pass along the track section. A rod at pivotally connected to each of such dogs and to the shaft A to which the connecting rods D between the track section and reciprocable pistons (Z d are pivoted, together with an interposed spring a serves to normally position such dog so that the engagement in question takes place just before the car engagesthe fixed stop a Reference has hcreinbefore been made to' the relationship of floating track-section A to upper car-delivcry trackC as though such track-section registered directly with the same, justas in fact it does with lower cardischarge track C. In the device as illustrated, however, and ordinarily when in use it is proposed to employ in connection with the car-delivery track a car spotter, that is a' device for controlling the passage of cars along such track so as automatically to place successive cars in position to be received onto the dumping mechanism proper. This car spotting device is accordingly interposed be .tween the track and the dumping. station and 'm the form illustrated comprlscs simply a tilting track-section E supported on a transverse shaft e. Track-section E is bent in a vertical plane so as to present two portions 0 c respectively adapted in different positions of the section to register with'track C and with floating track-section A. \Vhen portion a" is thus in register with track-see. tion A, portion a is raised sufliciently to act a stop, preventing the entrance ofa car. thereon. Similarly, a car after being received onto tilting section E is normally prevented from being discharged onto section A by horns c mounted upon longitudinally disposed resiliently supported, rock-shafts e and adapted to engage in the case in hand the car axle, although, obviously, if found desirable they can just as well be arranged to engage the wheels of the car. Springs 2 serve to thus normally position horns e to act as stops, while arms 6 extend inwardly and are so disposed as to be engaged by the.

rear end of floating track-section A, as the,

latter finally comcs'into its full raised position, the effect of such engagement being to depress'the horns and allow the car to move onto the dump. Celerity in such movement is secured by the additional inclination attained by having track-section E bent in the manner previously described.

In the device as shown the track-section A is likewise effective to tilt the section E into its discharge position. If desired, however, thismovement may be anticipated by so shifting the axis a of the tilting track-section as to permit the weight of a loadedcar,

- when received thereon, tooverbalance the same, thereby leaving the horns 6 alone to be operated by the track-section A.

' The operation of the dump should be.

per G of the superposed tracks.

' regulation of the supply of steam to such cylinder, as alsobythe retarding effect of cylinders D which can be varied'bysadjustment of valve 03 Upon thus being depressed the forward shaft or of the track-- section is guided downwardly and forwardly until the rolls a borne upon its ends rest on the lower ends of the corresponding guideways B, the rolls upon the rear shaft passing, incidentally to suchmovement, from within the branched portion 13 of the rear guide-way B full into such guide-way B ig. 3, Fromthis initial dumping position, the car is adapted to be tilted into a still more sharply inclined position by simply increasing the pressure within the powercylinder D, whereupon the track-section is tilted about the forward shaft as an axis until the guide rolls borne by the rear shaft restagainst-the upper'ends of the corre- 'sponding guide-ways, Fig. 4'. In order to facilitate thedischarge of the cars contents, the tracksection may be oscillated backand forth through a, shortarc withsuch degree of violenceaslwill be necessary to discharge the coalfrointthe car, such oscillation being secured byadrfiitting the'proper amount of steam into the power cylinder as will be readily understood. When the car .is inally emptied, the pressure within the pow r cyl lnder is againrelie'ved, so as to permit the rear end of the track-section to swing downwardly until the rolls borne by the rear shaft .shown in Fi 'of cars, either empty or 3 rest in thelower ends ofthe corresponding rear guide-ways. Inthisposition the track section inclines rearwardly and registers With the lower of the two superposed tracks, the degree of such inclination being suliicient to cause the canto-move promptly oif onto the track. Thetendency of the resiliently supported secondary stop A will obviously movement. The position of the parts at the conclusion of the discharge movement is 5. Upon pressure being again supplie to the power cylinder, the movements just described are reversed and the whole track-section is elevatediand the shafts with the guide rolls restored to their be to help start thecarupon this discharge normahpositions in which the track regis --ters with the upper track-section.

The operation of the spotting deuibe, an tomaticallyefiected as .it is by the several movements of the floating tracksection, just described, occurs simultaneously with such movements and need notbe further noticed since the correlation betw'" i the operation of the two devices should-be ufficiently clear already.

Obviously "the mechanism just described is equally adaptable to the simple transfer afifid, from one superposed track toanother, which event the angle, oflinterhied'iate 2 ing inovemenfof the-traeir-section from register with one'to the other of the tracks'C C, would not be made so steep as to disturb the contents of the car$ The track-section, furthermore, being-power actuated may be reversed in its operation to raise. cars from the lower to the upper track, if desired, and incidentally dump the same. Moreover as to the car spotting device this is suscept ble of advantageous use in connection not only with the present specific form of dumping mechanism but also in conjunction with any movable tracks'ection designed to receive cars one by one from a fixed car-delivery track; or, indeed, simply to control the pasnation, pend- 'sageof the cars from one portion to another of a discontinuous track;
