DUMP-CAR.

SPECIFICATION forming' part of Letters Patent N0. 719,794, dated February 3, 1903.

Application led September Z0, 1901. Serial No. 75,932. (No model.)

To @ZZ whom it may concern.-

Be it known that I, HARRY STILLsoN HART, a citizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Dump-Cars, of which the following is a specification.

This invention relates to that class of cars known as dump-cars, and particularly to 1o the construction thereof by which adumpcar of large carrying capacity is obtained, al1 of which will be more fully hereinafter set forth.

The principal object of this invention is to provide a dump-car with a longitudinal A- shaped hopper portion, swinging side hopper-boards, and vertical side boards arranged considerably above the hopper to obtain an automatic dumping-car of larger carrying zo capacity.

Further objects of the invention will appear from an examination of the draw-ings and the following description and claims.

The invention consists principally in a dump-car in which there is combined a-sup porting-frame portion, side boards therefor, and an A-shaped portion arranged longitudinally of the car, with its apex substantially at the longitudinal center thereof and at the 3o ordinary floor-level, the leg portions of which extend downwardly and outwardly to a point substantially outside the supporting carwheels. y

The invention consists, further, in the combination of a supporting-frame portion provided with the usual car-wheels, vertical side boards, an A-shaped hopper portion arranged longitudinally of the car, with its apex substantially at thelongitudinal center there- 4o of and at the ordinary floorlevel, the leg portions of which extend downwardly and outwardly to a point substantially outside the car-wheels, and swinging hopper-boards depending downwardly and inwardly to meet the leg portions, complete a pair of (or twin) hoppers, and form discharging-doors therefor.

The invention consists, further and finally, in the features, combinations, and details of construction hereinafter described and 5o claimed. l

In the accompanying drawings, Figure lis aside elevation ofva portion of a car constructed in accordance Withthese improvements; Fig. 2, a plan view of the same looking at it from above and showing the parts arranged to form a twin-hopper dump-car; Fig. 3, a longitudinal sectional elevation taken on line 3 of Fig. 2 lookingin the direction of the arrow; Fig. a, a cross-sectional 6o elevation taken on line of Fig. 3, showing the parts arranged to form' a twin-hopper dumping-car of maximum carrying capacity; Fig. 5, a cross-sectional elevation taken on line 5 of Fig. 3, showing the parts arranged 65 to form a flat-bottomed gondola car; and Fig. 6, a cross-sectional elevation showing a part of the mechanism taken on line 6 of Fig. 3 looking in the direction of the arrow and with the inclined end board laid in a flat plane.

In illustrating and describing these improvements I have only illustrated and described that which I consider to be new, taken in connection with so much as is old as will properly disclose the invention to others and enable those skilled in the art to practice the same.

In constructing a dump-car in accordance with these improvements I make a supporting-frame portion, which is preferably com- 8o posed of a pair of side sills a, center si-lls b, end sill c, cross-beam d, and intermediate sills e, all arranged to receive the shocks incident to the use of and distribute the same throughout the proper elements of the car. To provide for the carrying of the load, a pair of vertical side boards f is secured to the supporting-frame or underpinning and preferably connected together for purposes of stiffening at their end portions by a pair of ver- 9o tical end boards g, which, as shown in Fig. 3, is secured to and rests upon the end sills.

To provide for the automatic dumping of the load and at the same time to form a largecapacity car, an A-shaped-hopper portion is provided and arranged longitudinally of the car, with its apex h substantially at the longitudinal center thereof. It will also be noticed from au inspection of Fig. 8 that the apex is arranged substantially at the ordinary floor-level and not only provides a car of large carrying capacity, but one in which the entire load will discharge itself, and thus dispense with all of the manual labor of shoveling. The legs t' andyl of this A-shaped portion, as shown in Fig. 4, extend downwardly and outwardly to a point substantially outside of the supporting car-wheels-that is, all of the load discharging over 4such legs will pass to a point outside of such wheels, thus providing for a car that may carry any material that it is desired to discharge outside of the trucks and prevent the derailing of the car. To complete the hopper portion-that is, to form a pair of (or twin) hoppers-a pair of swinging hopperboards 7c is provided, hinged, preferably, to the under side of the side sills and depending downwardly and inwardly to meet the leg portions above described. only complete the twin hoppers, but they also form the discharging-doors therefor. A pair of shafts Z Z is provided and connected to the swinging hopper-boards by means of the chains m m, which act to lock such boards in position or permit them to be opened. These shafts should be provided with ratchet-andpawl mechanism (not shown) to prevent their being operated only at desired times, all of which is understood in the art. An inspection of Fig. 3 will show that the supporting carwheelslimit the length of the twin hoppers and that therefore some means must be provided for carrying the load above the wheels and permitting it to be automatically discharged when desired. To accomplish this result, a pair of inclined end boards In n is provided and inclined substantially from the apex of the A-shaped portion upwardly and over the car-wheels to a point adjacent to the stationary vertical end boards. This arrangement, it will be seen, eifectually dispenses with all manual shoveling. To still further increase the carrying capacity of the car whenever it may be desirable or necessary, a foldable extension p is provided for each side board, which in one position is folded upwardly (see Fig. 4) to rest on the upper edge of the side boards and provide for the carrying of the maximum load, while in a second position (see Fig. 5) they may be dropped downwardly and substantially out of the way.

At times it is quite desirable, and indeed necessary, to provide for the conversion of this type of car into a gondola car. To provide the necessary elements for this conversion, a pair of supplementary side boards qq are made and arranged to be raised in a vertical plane and form, as it were, supplementary side boards for the twin hopperin one position (see Fig. 4) orlaidina {iatplane and form a portion of the bottom of a gondola carin a second position. (See Fig'. 5.) These supplementary side boards may be provided with These swinging hopper-boards nothooks (not shown) to more effectually hold them in their vertical position. The inclined end boards (see Fig. 3) are also held foldably in position by means of the struts r, which may be removed by withdrawing the connecting-pins s, and thus permit such end boards to be laid in a dat plane and complete the bottom of a gondola car.

I claiml.
