5, 1909. 'Serial No. 52 ,404.

T all whom it may concern:

Be it known that l, (hr-mans Pl. CLARK, a resident of Grafton. in the county of Allegheny and State of Pennsylvania, have invented certain ne\ and useful Improvements in ()re Dump-Cars, (it which the following is a specification.

. This is a division of my application 50- rial No. 456,.J77, tiled October 5, 1908, and has particular reference to doors of novel form for the bottom opening. The doors close beneath said opening. and one object is to'provide the doors with wallming portions for the door-inclosed space.

A further purpose is to so form the doors as to prevent material from overflowing the door ends when discharging from the hopper.

Still a turtner purpose is to provide doors which may move to and from full open position without interfering with other parts of the car adjacent the doors.

In the accon'ipanying drawings, Figure 1 is a-vcrtical section of a dump car, taken online ll of Fig. 2, and Fig. 2 is a vertical cross-section on line of Fig. 1, the doors being shown open in dotted lines.

Referring to the drawings, 2 are the side sills, 9 the side sheets or girders, and -11 the sloping end floor sheets which meet the lower vertical portions 10 of sheets 9 to form the hopper month which bounds the bottom opening.

In the present adaptation the bottom opening is closed by doors located therebeneath, the space between said opening and the ('loorsdmreasing in depth from each side inwardly to the center where the doors close together. Two oppositelyinclined bodily movable door-s15 are shown, each supported at its ends by wheels 21 and' 23 secured to the door ends 16, Wheels 21 moving on inclined tracks 24 at the center of the car, and Wheels 23. on inclined tracks 26 at opposite sides of the car. The doors may be actuated by any suitable mechanism. In the present adaptation the upwardly extending end portions 16 of the doors are of substantially triangular shape, their top edges on being horizontal when closed to fit the lower extremities of end sheets 11, and their inner edges 6 verticaland 'closing together, as shown. The upwardly extending portions 16 thus form end walls'for the door-inclosed space beneath the hopper opening, and when 'said opening when the doors are I closed.

Also, the flared ends direct-the discharging material onto the longitudinally contracted portions of doors when open. Doors of the form shown, longest at the most elevated portions adjacent the car sides and decreas ingin width toward their inner lower edges.

may move to and from, full open position without interfering with other parts ol the car having fixedposition relatively to the doors.
