DUMPING-CAR.

SPECIFICATION forming part of Letters Patent No. 525,741, dated September 11, 1894.

Application led April 5, 1894:. Serial No. 506,399. (No model.)

To @ZZ whom it may concern.-

Be it known that I, GEORGE T. MORRIS, of Guttenberg, Hudson county, New Jersey, have invented an Improved Freight-Car, of which the following is a specification.

This invention relates to a freight car of peculiar construction and having a divided box which will discharge its entire contents when tilted.

In the accompanying drawings: Figure lis a side elevation of my-improved freight car; Fig. l, a top View of the same on a reduced scale; Fig. 2, a vertical longitudinal section on line 2, 2, Fig. 3; Fig. 3, a bottom View of the car; Fig. 4,a cross section on line 4, 4, Fig. 3, and Fig. 5 a cross section on line 5,5, Fig. 3.

The letters ct, represent the side sills; a', the center sill and a2, the end sills of a freight car, reinforced by suitable bottom timbers a3.

The box of the car is divided transversely at the center, so that two separate sections b, are formed. Each of these sections is provided at or near the center with -a shaft b', turning in bearing blocks b2, secured to the side sills a. The shafts h', carry at one end a ratchet wheel c, engaged by a pawl c', which in turn is engaged by an eccentric o2.

The bottom b3, of each section b, is slotted at the center, as at b4, (Fig. la) so that the bottom is able to straddle the center sill a', when the boxes are tilted. In order to form aflush surface at this opening, the center sill ct', is provided with a central projection a4, (Fig. 5) that extends upward ush with the surface of bottom b3. At their junction, the two bottoms b3, are jointly supported upon au arm d, made of a double U shape, so as to straddle the center sill, and to reach up to the bottoms b3, to the right and left thereof. This arm is pivoted to the center sill and also to side pieces e, projecting upwardly and downwardly from the side sills a. At one of its ends the arm d, carries a finger d', engaged by a dog cl2, and limited in its motion by stops d3.

In order to dump the car, the dog d2, is first swung aside and then the arm d, is revolved by a wrench applied to a squared head d4.

In this way the inner ends of the bottoms b4, 5o

are left unsupported. Next, the eccentrics c2, are swung aside to liberate the pawls c', and the latter are swung out of engagement with the ratchet wheels c. A wrench is now applied. to squared heads c3, of shafts b', so as to tilt the boxes b, inward, which operation may be facilitated by stepping upon the inner unsupported ends of the boxes. It will be seen that in this way both boxes discharge their entire contents automatically beneath the center of the car, which is the object desired.

The inner upright edges of boxes b, are rounded or cut away (dotted lines Fig. l) to permit the proper motion of the boxes. These edges are covered by suitable face plates e', secured to the side pieces e, and connected by a transverse rod e2.

In order to brace the car, I employ the outer brace rods g, g', that extend over the top and bottom of the side pieces e, and are connected at their ends to caps g2, secured to the ends of side sills a. The rods g, g', may be connected to such sills by the diagonal braces g3.

If desired the sides, ends and bottom of the boxes ZJ, may be provided with double walls, to form a steam jacket h, having inlet 71,', and outlet h2. Steam is admitted into this jacket during cold weather to thaw the frozen contents of the car.

What I claim isl. The combination in a freight car of a divided pivoted box with a center sill ct', a pair of central supporting shafts, and with abent revoluble arm that supports the free ends of the box sections, substantially as specified.

2. The combination in a freight car of a divided pivoted box with central supporting shafts, and intermediate supporting arm and a pair of face plates e', that extend over the inner ends of the box sections, substantially as specified.

3. The combination in a freight car having side sills and a center sill with a divided box having a slotted bottom adapted to straddle the center sill and shafts b', supported on the side sills, substantially as specified.

divided box, shafts b', arm d, sides pieces e, and brace rods g, g', substantially as specified.
