DUM Pl-NG-CAR.

SPECIFICATION forming part of Letters Patent No. 740,819, dated oci-.ober e, Ieos. Application iiled February 27, 1903. Serial No. 145,301. (No modali` To all whom it may conceive:

Be it known that I, WILLIE Hoses. Davis, a citizen of the United States, and a residentv of Parachute, in the county of Garfield and State of Colorado, have invented new and useful Improvements in Dumping- Cars, of which the following is a full, clear, and exact description.

My invention relates to certain novel andt Io useful improvements in cars, and has particular application to railway dumping-cars.

In carrying out the presentinvention I have particularly in contemplation the construci tion of a dumping-car of the hopper-bottom I type, wherein a load of dirt, coal, ore, or similar material passing through an opening in the bottom of the car will be directed to predetermined points or places alongside said car and out of the way of the Wheels thereof.

A further object of my invention is to provide an improved means for covering or closing the opening in the bottom of the hopper.

of the car, which means will enable a load of dirt or other material to be conveyed in the. hopper from place to place; but when said means are opened or released the material will be directed down along the surface of the I have also as an object the construction ofa car which shall be exceedingly simple, and at the same time the parts thereof shall belso arranged and correlated thatthe structure will be enabled to withstand the great wear and tear to which cars of this character are usually subjected, owing tothe nature of the material which they must convey.

With these'and'other objects of a like nature in View my invention consistsin the construction, combination, and arrangement of parts, as is described in this specifica-tion, de-

lineated in the accompanying drawings, and set forth in the appended claims.

, Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in allthe {igu res.

Figure 1 is a central longitudinal vertical sectional view taken through a dumping-car Aon the line l l of Fig. 2.

Fig. 2 is a top plan view of the same. Fig. 3 is a transverse vertical sectional view taken on the line 3 3 of Fig. 1. Fig. 4 is a transverse vertical sectional view showing the parts in position for depositing the load immediately beneath the body of the car, and Fig. 5 is a perspective view of one of the load-directing chutes.

Referring now to the accompanying drawings in detail, A designates the body portion of a railway freight-car of any suitable character-sucb, for instance, as one of the type commonly used for transporting dirt, ore, coal, or the like. This car is formed with a number of hoppers-two in the present instancewhich hoppers are shown at I and 2 and are formed by the downwardly-converging walls 3, 4, 5, and 6, extending transversely of the car. The door or bottom portion of the car within this hopper is cnt away to provide an opening, the base or door of the hopper being formed by the swinging sections `or plates 7 and S,

which are hinged upon a rod Q,'extending longitudinally centrally of the bottom of the hopper. This longitudinal hinge or pivot-bar 9 may be supported in any approved manner beneath the hopper, and in the present instance I have shown it journaled or bearing in the blocks or timbers lO 10, extending transversely beneath the car at points adjacent to the side edges of the hopper. Secured to the hinged plates '7 and 8 near the free end thereof are eyes ll 1l, to which are secured chains 12 I2, adapted to be wound about the crank-rods 13, Vextending across the hopper near the top ofthe car, such rods being provided with handles la 14 and also have small ratchetwheels 15 mounted'there'onadjacent to the longitudinal sides of thevcar, and the teeth or serrations of Ysaid wheels are adapted to be engaged by dog'sxor pawls 16 16, pivoted to the sides of said car. By this construction itwill be seen that the plates or hinged sec- IOO tions forming the bottom of the hopper may be operated to open or close the exit through the hopper by turning the crank-rod, thereby winding the chains, the rod being prevented from turning or reversing by the dogs or pawls just described. v

Secured to the timbers 10 l0, extending beneath the hopper of the cars, are a number of supporting-bars 17, which are preferably in the form of angle-irons, and to one of the sides of said angle-irons near the outer ends thereof are pivoted, as at 1S, the directing chutes or scoops 19 19, there being two chutes for each hopper, and as will be seen particularly on reference to Figs. 3 and 4, the chutesl extend in opposite directions toward the sides of the track. These directing-chutes are so pivoted relative to the hopper and the bottom-forming plates that when they are in the position shown in Fig. 3-that is, inclined downwardly and outwardly from the car in a position almost perpendicular-the plates 7 and 8 may be lowered to rest upon the bottom faces 2O 2O of said chutes, and any material iiowing from the hopper may be directed down the plates 7 and 8 along the chutes to the point of discharge to the side of and away from the car; but if it be desired to deposit the lmaterial directly beneath the car the chutes may be moved upward and outward to a position horizontal relative to the car through the medium of chains 21, which are secured, through the agency of brackets 22, to rings or eyes 23, formed near the ends of the chutes, while the opposite ends of said chains maybe wound about drums 24 24, secured to the sides of the car, which drums are controlled through the medium of ratchets 25 and the pawls 26 engaging with the teeth of said ratchets.

From the above description, taken in connection with the accompanying drawings, the construction and operation of my improved dumping-car will be readily apparent.

When the car is to be loaded, the crankrods 13 are turned to draw the plates 7 and 8 into a horizontal position, thereby closing the opening in the bottom of the hopper, and the car or bins are then filled with the material. If it be desired to remove the material from said car and deposit the same alongside the track, the chutes 19 are lowered, through the medium of the chains 21, to a position approximately as shown in Fig. 3-that is, said chutes being at a pronounced downward inclination relative to the hopper-bottom-and the crank-rods 13 are turned to permit the plates 7 and 8 to rest upon the bottom portion 20 of the chutes. The material through the force of gravity then flows or passes from the hopper down the plates 7and 8 and is directed by the outwardly-inclined chutes to points alongside the oar or away from the body thereof; but if it is intended to deposit the material immediately beneath the carfor instance, beneath the tracks-the chutes 19 are elevated through the chains 21 to a position substantially as shown in Fig. 4-that is, horizontal to or parallel with the car-bottom-and the plates 7 and 8 are then released, and as they occupy the position shown in Fig. 4 the material will readily drop down to a point below the hopper.

While I have'shown and herein described one particular embodiment of my invention, I wish it to be understood that I do not limit myself to the precise details of construction shown herein, as there may be modifications and variations in some respects without departing from the spirit of the invention or sacrificing any of the advantages thereof.

Having thus described my invention, I claim as new a-nd desire to secure by Letters Patent- 1. Adumping-car having an opening formed in the bottom thereof, hinged plates designed to form a door for said opening, said plates swinging outward relative to each other, to close said opening, and pivoted chutes mounted adjacent to said plates, the construction being such that the chutes are adapted to receive material from the hinged plates, and directsuch material alongside the car when the plates are inclined relative to each other and lie above the chutes, but when the plates hang approximately parallel and thechutes are moved on their pivots, away from said plates, the material will be deposited beneath the car.

2. A dumping-ear having an open bottom portion, hinged plates adapted to form a floor for the open bottom portion, means for moving said plates to open and close the bottom, such means comprising a rod rotatably journaled in the car, and chains connected with the rod and with the hinged plates, pivoted chutes beneath the hinged plates for directing material from the car toa point alongside the track, and means for moving the chutes on their pivots, substantially asset forth.

3. A dumping-car having an open bottom portion,a movable door for said bottom,chutes pivoted to swing beneathand to the side of the movable Iioor for receiving and directing the material in the car to a point alongside the car, when the floor is in its open position, and means connected to the chutes and operated from outside the car for moving the chutes on their pivots, substantially as set forth.

4. A dumping car having an opening formed in the bottom thereof, a hinged iloor for said opening, and chutes pivoted beneath the hinged floor, said chutes having vertical side walls, such chutes being adapted to direct material from the oor to a point alongside the car when the fioor rests in contact with the bottom of the chutes and between the vertical side walls thereof, substantially as set forth.

5. A dumping-car having an open bottom portion, a shaft extending beneath said opening, plates hinged to said shaft and adapted to be moved to a horizontal position to close said bottom, and material-direction chutes IOO IIO

pivoted beneath the hinged plates, said chutes having vertically-extending side Walls, tapering or decreasing in height toward the outer ends of the chutes; the construction being such that when the plates rest upon the chutes between the vertical Walls the material will be directed down such chutes to a position alongside the track, but when the chutes are moved on their pivots ont of contact with the plates the latter will permit ,the material to drop directly beneath the car.

6. The combination of a car having an open bottom portion, hinged plates adapted to form a Iioor for the open portion, crank-rods journaled in the car, and chains encircling said rods and connected with said plates for supporting the same in a closed position, pivoted f WILLIE HosEA DAVIS.
