3. In a dump car, a bottom therefor comprising two hinged parts, a U-shaped lever comprising arms or side pieces pivoted to the ends of the car, and pitmen and links pivoted -between the said arms or side pieces and the free swinging ortions of the hinged parts and so dispose with relation to the hinged I bottom and the side pieces of the lever as to' hold the hinged parts in a closed position when the U-shaped lever is' disposed in a horizontal (position.

4. In a ump car, abottom therefor comprising two hinged parts, a U- shaped lever comprising arms or side ieces having curved portions pivoted to eit er end of the car ineans'connected between the hinged parts 40 an the curved portions for raising and lowprin the parts when the lever is manipuate 5. In a dump car, a bottom therefor comprising two hinged parts, a U-shaped lever comprising arms or side ieces having curved portions pivoted to sit er end of the car, pitmen and links connected between the curved portions and the free swinging. porthus fully described the invention, 1

tions of the hinged parts, said curved portions being so constructed that the pivots between the pitmen and the curved portions and the said links will be disposed in alinement with the pivots of the side ieces or arms when the U-shaped lever is t rown in a horizontal position.

6. In a dump car, a bottom therefor comprising two hinged parts, a U-shaped lever comprising a beam havin arms or side ieces connected detachabIy thereto and aving curved portions, said arms or side pieces being pivoted at either end of the car, pitmen connected to the extremities of said curved portions and links connected between the pitmen and the free swingin portions of the hinged parts, said curve portions being so constructed that the pivots between the pitmen and the curved portions and the said links will be disposed in alinement Withthe pivots of the side pieces or arms when the U-shaped lever is thrown in a horizontal osition.

7. In a ump car, a bottom therefor comrising two movable parts adapted, when eing opened,- to swing outwardly toward either side' of the car and downward,'a U- shaped lever comprising abeam having arms or side pieces connected detachably thereto and having curved portions, said arms or side pieces being pivoted at either end of the car, itmen connected to the extremities of sai curved ortions and links connected between the pitmen and the free swinging portions of the hinged parts, said curved portions being so constructed that the pivots between the pitmen and the curved ortions and the said links will be disposed in alinement with the pivots of the side pieces or arms when the U-shaped lever is thrown in a horizontal osition.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
