DUMPING MECHANISM FOR RkILWAY-CARS.'

To all whom 'it may concern:

Be it known that I, EMANUEL FARAG, a c'tizeno'fthe United States, amd resident of Rochester, in. the Acounty.of Monroe and 5 State of New York, have invented certain new and useful Improvements in Dumping Mechanismy for Railway-Cars, of which the following is a specification.

This invention relates to dumping-mechanism of the type in which stationary devices, located adjacent a railroad track, operate automatically to discharge cars passing `along the track,` and to subsequently close the hopper-s of the ears after they have been discharged.

` One object of the invention is topro- 'duce mechanism of the type in question which shall beV simple and reliable in operation,` particularly through the `position of guiding-devices on the cars and on sald stationary means for insuring their proper coperative position.

A further object simplif and improve the dumping-mechanism o' the cars,whereby it is particularly adapted for convenience in discharging the" cars and returning them tonormal or closed position, whether by the 'useof the automatic means before referred to, or by manual operation.

Various other objects of 'the invention, and the details of construction by which they are attained, will be set forth in connectin with the Yfollowing description of the preferred embodimentfof the invention.

In the accompanying drawings F igure 1 is aside-elevation of mechanism embodying the present inventiom'including a dumping-car andy the track upon. whichjt runs,

o eratin the car; Fi .f2 isa plan view o the sidiject-matter o Fig. 1;` and Figs. 3 and 4 are, respectively, sectlonson the lines 3-3 and 4-4 in Fig. 1, looking in opposite direct-ions, as indicated by the arrows applied to said lines.

The general form of the dumping-car embodying the present invention is .not material, but the car is illustrated as having sides 6 connected by transverse partitions 7, producing two hoppers adapted to contain c'oal, or other material, in bulk. The body of Vthe cari-is supported upon the usual wheels 8 running upon `track-rails 9. The

.. par of doors 10, lwhich are pivoted to t-he Specification of Letters Patent.

body at 11 and engage the inclined lower ledges 120i the sides of the' hopper, when the doors are in closed position. The dumping-mechanism connected with the two hoppers is in all substantial respects similar,

and it will be obvious that the number of such hoppers and mechanisms employed upon the car is immaterial. The hopper- *doors 10 are controlled by links 13 pivoted to their'lower edges and extending upwardly to pivot-pins'14 projecting from slides. 15. These slides move vin vertical guides 16 and 17 upon the sides of the car. To retain the slides 15 in raised position, and thus hold the` hopper-doors closed, each slide is provided with `a notch 18 at one edge, adaptedto co crate withia detent 19. The detent is fixe in inclined position, to a rod 20, which passesthrough the body nof the Acar and simultaneously operates the detents on opposite sides of the car, the doorsbeing supported on both sides of the car by similar arrangement of links and slides.

The detents are held normally in operative en agement with the slides by means ofa spring 21, (Fig. 4,) which surrounds the rod' 20 and is confined, at its ends, between the 4sides 6 of the car. To protectthe rod 20 and the spring 21 from contact. with the contents of the car, these parts are inc losed by'a tubular casing E24, which is fixed, at its ends, to the sides 6 of the car, and is provided, at each end, with an enlargement 25 forming a recess 23 into Which one of the detents 19 mayfmove when disengaged from 4the corresponding slide 15, as shown in Fig.

4. The detents are moved to disengage the slides by means of the' extremities 26 of the rod 20, whichproject at each'side of the car.V By pushing upon either projection the rod 20 and the detents are moved horizon.-

tally to the' position of Fig. 4, or totlie corresponding opposite position, thus disengagmg the detents from the slides, whereupon the slides fall and permit 'the hopperdoors to open and discharge the contents of the hopper. This operation may be performed manually, but myinvention includes means .for accomplishing it automatically, as will be described later. Then the detents are moved ,to either dsengaging position one or the other of the detents engages the adjacent end of the spring 21, as shown in Fig. 4, thus compressing the spring. So long as the slides remain in their lower po- 4sition the detent in question is held in its inner position against the pressure of the spring' by engagement with the inner surfacerof the adjacent slide, but.'upon the subsequent-upward movement of the slide, in closing the hopper-doors 10, the detent in question is released and the springr 21 then returns the rod 20 and the detents 'to normalv position. l

To raise the slides 15v and close the hopperdoorrs whenthe car is'operated manually, each slide isl provided with rack-teeth formed on one edge, and thesel teeth are engaged by pinions 28 iixed on opposite ends of a shaft 29,' which passes through the body of the car. This shaftis protected by a casing 30 ixed to the sides of the car. Thej ends of the shaft are squared, as shown in F ig. 1, so that it may be turned by means of al -hand-crank (not shown) of ordinary form, thus causing the pinions tovraise the slides until the detente engage the notches The automatic means for controllingthedumping-mechanism include a framework which spans the. track, and through which the car passes when running on the track.

This frame-work comprises uprights '31, which are shown as mounted upon the ties 35 of the track. The uprights on each side' of the track are connected, near their tops, by a vhorizontal beam 32, and the uprights on opposite sides are connected by cross-bars 33.` Diagonal braces are applied to the top and thesides of the frame-work, and

angle-irons `36 connect vthe vuprights with the ties, as shown in 3, to frame-work laterally. K

To discharge the car automatically a cam is mounted upon one side of the framebrace the work, in position to engage the projection 26 as the car moves through the framework. This cam is in the form of a curved member 37, which is pivoted, at one end, between lugs 38 on one of the uprights 31. The other ,end of the cam is guided in a recessed block 39 mounted upon another upright, and this end of the cam is supported by a screw 40, which is adjustable to vary the position of the cam. ln Figs. 1 and 4 the cam is shown 'as in engagement with one of the -projections 26, thus .holding the correspond- 'ing detente in inoperative position. It will be noted that after the detents have been moved to this position, and the slides 15 have fallen, the detents are retained in such position by engagement with the inner surfaces of the slides, and cannot return to operative position until the slides have again position, although not in engagement with Vthe cam 37.

The coperation of thecam 37 and the projections 26 vrequires that the relative lat- -eral positions of the car and the frame-work .be substantially invariable. Owing` to irregular, loading of the car or unequal strength'in its springs, or to other causes, which will readily occur to those skilled in the art, Athis lateral relation might be easily disturbed, and accordingly I provide means for maintaining it automatically, when the car is passing through the frame-work. To this end the upper edges of the sides of the car are provided 'with' bars 41, which may be the usual stiffening-members ap plied at this point, but which also constitute longitudinal abutments, and, to cooperate with these abutments, rollers 42 a're journaled in recesses in the inner surface of the beams 32, these rollers being spaced 'apart a distance only slightly greater, than the' width of the car. Accordingly, when thecar enters the frame-work the rollers and .the abutments, by their coperation, movethe car transversely, if necessary, to the exact relative lateral position, with respect to the frame-work, which will permit the automatic mechanism to coperatevproperly with the dumping-mechanism of the. car.

In addition to dischar ing the car, the automatic mechanismis ao provided with means for returning the vdumping-mecha- -nism of the car to normal or closed posi'- tion upon a return movement-.of the carv through the stationary frame-work. To' this end each slide 1-5 is provided with anY outwardly-projecting pin 43, which constitutes alcam-follower adapted to coperate with an inclined cam 44 mounted upon the` frame-Work. The main portion of this cam is 'inclined in a direction to raise the pin 43 when the car returns through the framework, that -iSgin the direction from right to left in Fig. 1, but the upper end of the cam is provided with a 'short opposite1y inclined portion 46, this portion being provided so .that when the loaded car passes from leftv to right through the framework any engagement of the pin 43 with the cam which may occur at this time shall besuch as to permit the pin to pass over the cam. Forthe same purpose the cam is mounted inovably upon 'the framework, its lower end 'being pivoted, at 45, to one of the up` rights, while its upper end is guided in a verticalA slot formed in -a casing 47 fixed to another upright. Within this casing is a plunger 48 which supports the upper end of l theI cam, this 4plunger being, in turn,v supported" bya compression-spring 49 inclosed within the casing 47. A The lower end of the spring isfsupported by .a screw 50,

by which the compression of the spring may than the position to which they `are raised by the ,cam 44 in closing the .dumpingmechansim duringthe return-.movement o the empty car. Accordingly, when the loaded car passes from left to right through the frame-work,

46 of the cams, they may depressthe cams by compressing the springs 49.

A pins.

VAsit. may be desirable to avoid the.

gagement just described between the pins 43' and the cams 44, particularly when a train of heavily loaded cars passes through the stationary frame-work, mea-ns are provldedfor depressing the cams manually to` hold them out of engagement with theA as shown particularly in Figs. land 3, i

. of the hoppers is,

'movement of the car Ior ears,

When a car, o r train of cars, constructed as'above described passes through the stationary frame-work from lett to right, each in turn, discharged when `it reaches .the position indicated generally by the line 4-v4 in Fig. l. .Ulpon a returneach of the hoppers is again closed by the mechanism above describ ycharged and closed automatically at the required point. In F ig. l the. car is shown as at a point in its return movement where the left-hand hopper has been partially closed, While the right-hand hopper is still'entirely open. y

l It will be apparent that since the rod 20 and thel detents may be moved horizontally in either direction to disengage the slides, owing to the symmetrical" construction ot these parts,fthe.car will be automatically discharged in passing side of the car may toward this cam, and it is, necessary to arrange the cars in any particular position in the train. It will also be apparent that the arrangement of the slides l5, the links 13 and the doors 10 is such that in closing the doors :a single cam, such as the cam 44, located at one sideof happen to be presentedl therefore, un-

the track, will begsulicientA to restorethe to the embodiment p'arts of the dumping-mechanism to normal position, but in 'order to relieve the parts. of unnecessary strain it is preferable to employ duplicate cams on opposite sides, where this can conve-nientlybe'done, as shown in the drawings. My invention is not limited thereof hereinbe'fore de-- scribedand illustrated inthe accompanying dra-wings, but may be embodied in various I other forms within the nature of the inven- 'tion as it is defined in the following claims.
