To all whom it may c'zmcem: v

Be it known that 1, .WILLIAM F. KmsEL, Jr., a citizen of the United States, and residing at Altoona, Blair County, State of Pennsylvania, have invented certain new,

and useful Improvements in Dump Cars, of which the following is a'specification.

This invention relates to dumping vehicles and particularly to railroaddump cars of the side door type, which are especiall adapted for conveying. dirt, cinders or ba last, such as broken stone or avel.

The principal objects of the invention are; to provide a dump car of thls class whlch may be conveniently loaded by a workman standing on the roadbed alongside of the same; which maybe easily dumped when of the car; which is so desi it is desired to discharge the contents thereof by an operator stationed on the platform at either end of the car or by the joint action of two operators one stationed at each end ed that the load carried may be dumped in its entirety to one side of thecar or a part of the load on one side and a part on the other side of horizontal and held in such position as long' as desired. Other objects and advantages of the invention will become apparent as it is disclosed in the following description when taken with the accompanying drawings, in which:

Fig. 1 illustrates partially in side elevation and partially in longitudinal section a rail road dump car embodying the features of the invention, the running gear being omitted for the sake of clearness;-

Fig. 12 is a section on line 12-12 of Figure 5; v

Fig. 13 is a detail; and

Fig. 14 is a cross section through a member illustrated in Figures 9 and 10.

The frame of the car has the usual end bolsters 9 which are connected by a center sill 10 extending continuously from one end of the frame to the other, this'center sill bemg preferably formed as illustrated, of parallel channel members laced in close proximity to each other an arranged back to back with a plate 10 secured to and connecting theirtop flanges, as shown' in Figure 4. The frame has no side. sills. Upon the end platforms may be mounted the usual brake operating mechanisms, bump cam ers, etc. which will not be described in detail, formlng no part of the present inven tion. Bearmg blocks 11 are supported on the center sill, these blocks being ositioned toward the ends of the sill and ad iacent the end platforms. Each ofthese blocks comprises a strong casting or forgin and is formed withupwardly extending anges 12 which extend longitudinally of the car and have semicylindncal upper surfaces which comprise bearings upon which rest corre apondingly formed seats 13 of an intermelate block 14;. Each of these blocks 11 has an opening therethrough between the spaced flanges 12 which receives the downwardl projecting tongue 14' of intermediate ,bloc

14. The side faces of these tongues 14' are curved concentrically with the curved upper surfaces of the flanges 12 so that when the car body is tilted, as illustrated in Figure 4, the tongue 14' will not bind a ainst'either of the flanges 12 to interfere wit the tilting action.

The tilting body, which is preferably fabricated entirely of steel, is rectangular in plan, with upwardly inclined floors at the ends thereof, as clearly illustrated in Figure- 1, and rigidly secured beneath the upwardly sloping end portions are brackets 15, the lower ends of these brackets being provided with elongated. transverse seats which mil jing blocks serve to prevent lateral'displacement of the tiltable body relatively to the supporting frame when the body is in its ex treme position, as illustrated in Figure 4 or,-

when due to vibrations caused by a'rough roadbed, the body has a tendency to jump laterally relatively to the frame. The in: termedmte block is held in position by the weight of the car body and if the body is lifted by power means the blocks may be removed and inspected and replaced by blocks of different size, if necessary to adjust the relative heights of the'ends of the dump body. i

The central longitudinal floor supports 16 of the body are upwardly inclined at their ends, but the horizontal middle ortions of these members are located to sit er side of the center sill 10 of the frame andnot above the center sill, as in side dump cars hereto desi ed or suggested. The central portion of t e car floor 1s rigidly supported by these beams while at the same time the floor is not elevated because of them, but occupies a position at an elevation about forty inches from the roadbed, in this particular embodiment of the invention, an elevation which may be readil reached by the shovels of workmen stan in gaged in loading t e car. The center sill 10 the floor sup orts 16vdo not contact or interfere with eac other in any manner in tilting thecar, which, may be rotated to any angle permitted b the Windlass mechanism hereinafter to be escribed. I

The body has four-swinging ,doors 17 on each side, these-doors being pivotally sup" is divided into a series of communicating com artments. The latch mechanism'control mg the doors is so arranged that any one or any number of the doors may be been tilted. v The doors 17 are pivotally mounted on on the roadbed and enopened so that when thecar is tilted the contents may be either partially or wholly discharged as desired, the triangular intermediate brackets serving to retain a considerable portion of the cargo in a closed compartment even when the door of the adjoining compartment is open and in spite of the fact that part of the contents of the compartment may escape through the opening between the brackets or bracket-partitions.

The end compartments are, of course, shaped differently from the intermediate compartments, the floor of the end compartments being inclined and. these compartments are therefore not provided with doors, any material therein'being necessarily -discharged" through'the door of the ad'acent compartment when the car'is du'm e To prevent material-being retained int ese end compartments each 18 provided with two sloping plates 22, the lower edges of each plate being secured to. the inclined car floor and the upper edges of which are secured to the top of theside wall of the compartment and 'to one of the triangular end brackets20 respectively. Material can not be retained, therefore, behind these end brackets20, but ours through the opening between them an out through the adjacent-- compartment when the door of the adjacent compartment is unlatched, and the car has bars 18 which are in turn rotatably mounted in bracketsv23 supported u on the side sills 24 of the car body, and t e doors are secured intheir closedp'ositions by latches mounted on the triangular intermediate bracket-partitions and. end brackets and which are adapted. to engage the upper portion of each door ateach end thereof to hold a the'doorclosed against-the ressure of the material *in'the car. On'eac of the intermediate brackets 19 are. supported latches for securing the adjacent ends of two doors,

while on the end brackets 20 are latches for securing only ,the outer ends of the end doors.'-

In Figures 6 and 7 a set of intermediate latches 1s clearly illustrated. Each of the doors adjacent one of these latches is notched as at 25 and is provided with a reinforcing plate or catch 26.1.-A horizontal axle orshaft 26 extends transversely through the latch housing 21 and pivoted on this shaft are three latches, a cent er'latch 27'having projecting lugs 28' each of which two side latches, each e center latch has forwardly extending I fingers 29 having aligned apertures therein in which is mounted a short shaft or axle 30. This axle rotatablysupports the upper end of a link 31, the lower end of which is ivotally connected to an arm 32 bolted to s aft 18 for rotation therewith. The side latches 33 are slotted and are adapted to be lifted by hand to disengage catches 26 and to be movedrearwardl from the full line position to the dotte line position Figure 6), where they will rest within the atch housing until again drawn forwardly and placed in operative position. The center latch 27 will be raised by the connecting link 31 which is actuated by the arm 32, when the shaft 18 is rotated by means of an operating handle 34.

Each end latch housing 35 has a transverse axle or shaft 36 which rotatably supports a manually operable latch 37 and a second latch 38 adapted to be operated by a link 39 connected to shaft 18. In Figure 8 an end latch housing and the two latches therein contained are clearly illustrated, the end of a door being indicated at 17 and each of these latches engaging a catch 40 secured below the notch 25 of the door.

It will be seen, therefore, that each door of the car is held in closed position by two sets of latches, one set of which is raised when the lever 34 is manipulated to rotate shaft 18, and the latches of the other set being lifted individually by hand. Inasmuch as no door can open when the car is tipped unless both sets oflatches are disengaged, it is obvious that any single door or any particular doors, selected may be opened for dumping while the other remain closed. If all of the manually oper' able latches along one side of the car are raised and placed in inoperative position, all of the doors will be completely unlatched when the lever 34 on that side is manipulated.- On the other hand, if the manually operable latches controllin any particular door are not raised, that oor Wlll remain closed when the power operated latches are raised. In this manner the amount of material dumped at any particular point may be readily controlled.

Windlass mechanisms for tilting the body are mounted at the ends of the car. Each of the mechanisms includes a drum 41 rotatably mounted on an axle 42 which is supported in brackets 43 and 44 respectively secured to the frame of the car, and means for rotat ing the drum by hand. A large gear 45 is rigidly secured to the drum 41 or is preferably made inte al'therewith, as shown in the drawings, an meshing with this gear'is a pinion 46 fast on shaft'47 which shaft is rotatably mounted in the U-shaped upper end of bracket 44.

The outer end of shaft 47 is squared and power is applied to the squared end'by means p]: a awl and ratchet mechanism to rotate e sentially an operating arm 48 having an en:

rum. This mechanism comprises eswith aligned apertures in which are journaled the hubs 52 of the ratchet wheel. The squared end of hub 47 extends through a correspondingly squared aperture in the ratchet wheel and supports the same and hence also the operating arm The reverslble pawl 50 is pivotally supported and either of its ends may be brought intoengagement with the teeth of the ratchet wheel for the purpose of rotating the same and the shaft 47 and drum 41 in either direction. To this pawl is pivotally secured a leaf spring 53 which extends rearwardly between the knife edges or abutments 54, througha slot in the transverse partition 55 and has its end in engagement with a cam 56. This cam is fixed on a short shaft 57 rotatably mounted in the walls-of the housing and has a segmental recess 58 therein adapted to receive the end of the spring as it rotates and to shift the end of the spring from one side of the cam to the other, causing it to pivot about abutments 54 as fulcrum points and to reverse the pawl 50.

To one end of shaft 57 is secured an operating lever 59 by means of which the shaft and cam may be rotated through substantially 240, the rotatory movement being limited by stops 60 against which the lever 59 abuts. In Figure 9 the cam is shown in one of its extreme positions, the end of spring 53 being forced to one side thereby and this spring serving as a lever, forcing one end of the awl 50 into engagement with the ratchet w eel. If it is desired to reverse the pawl, the cam is rotated inthe direction of the arrow (Figure 9) to its other extreme position, the end of spring 53 enter- .ing the recess 58 in the pawl as the cam is rotated and being forced from said recess as the cam approaches its opposite extreme position. By means of ;this pawl and ratchet mechanism, the shaft 47 and hence the drum 41 may be rotated in either direction as desiredj A chain 61 has its ends secured to the up-- per corners of the tilting body, this chain passing over sheaves 62 mounted in the. frame and passing twice around the drum 41, being secured thereto byv bolts 63. By rotating the drum, therefore, the chain on one side thereof is paid out and on the other side is drawn in, thus tilting the car. As a preliminary step, however, one of the grav- .1ty actuated pawls 64 must be raised'to allow the gear 45'to rotate. These gravity actuated pawls, when both are in engagement with: the teeth of gear 45 will prevent rotation of the drum in either direction, and will hold the car against accidental tilting or will hold it tilted toany angle founddesirable for dumping purposes.

The car may be operated from either end or, if desired, the Windlass mechanisms at both ends may be used simultaneously. When loaded the center of gravity of the body is a considerable distance above the fulcrum points thereby rendering it easyto tilt, while, when the body is empty, the center of gravity is very close to-the fulcrum points so that it has great stability. The design and arrangement of the various parts of the dump car may be changed as found convenient in practice and the invention is, of course, not limited in scope to the exact embodiment described and illustrated.
