SIDXEY D. KING, OF PITTSTON, PENNSYLVANIA.

DUMPING-CAR.

SPECIFICATION forming part of Letters Patent No. 336,119, dated February 16, 1886.

Serial No. 180,310. (No model.)

To all whom it may concern:

Be it known that I, SIDNEY D. KING, of Pittston, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Dumping-Cars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in dumping-cars.

On the 29th of May, 1883, Letters Patent were granted to me for an improvement in dumping cars, in which a car was shown and described having a transverse partition separating a pair of inclined hoppers, the door of the hoppers being arranged to open by the pressure of the load and close by gravity. A vertically-movable shaft forming a pintle on which the door-operating arms were hinged was provided with a rack bar adapted to be moved longitudinally by the vertically-movable shaft-pintle, and a rotary shaft was provided with a pinion adapted to engage the rackbar, and with a spur wheel in engagement with a pair of locking-pawls, by means of which the doors were locked in either a closed or open adjustment and released at pleasure.

The object of my present invention is to provide more simple, convenient, and economical means for transmitting the motions of the doors to the shaft carrying the spur-wheel for locking the doors in the desired adjustments, and for transmitting the motion of the said shaft to the doors, a further object being to simplify as far as possible the construction of the hopper and the mechanism for operating the doors and render the same more durable.

With these ends in View my invention consists in certain features of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a transverse vertical section taken on a plane between thedoors. Fig. 2 is a longitudinal vertical section through the center of the car, and Fig. 3 is a bottom plan View.

The frame-work of the car consists, prefer ably, of the side rails, A, connected by the end beams, a, a pair of centrally-located crossgirders, B, and the pair of centrallylocated longitudinal girders Z). The entire bottom of the car, or the bottom with the exception of a short distance from each end, is constructed hopper-shaped, both the sides 0 and the ends 0 extending obliquely downward toward the oblong mouth or opening I), and firmly held in position by metallic bands (I. From the ends of the opening D perpendicular walls E extend upwardly to the cross-girders B,which, in conjunction with oblique ends 0, adapted to fit the oblique sides 0 of the hopper, serve to prevent the contents of the cargrain. coal, &c.from gaining access to the opening D, excepting through the spaces between the lower ends of the inclines O and the lower edges of the cross girders B. A pair of doors, F,

adapted to completely cover the openings between the lower ends of the inclines O and the lower edges of the cross-girders B, are hinged to the lower edges of the crossgird ers B, and when in closed adjustment occupy oblique positions, with their free edges somewhat fart-her apart than their hinged edges. Midway between the two doors F a pair of brackets,G, are secured to the walls E-one to each-and provided with elongated vertical slots or grooves g. A cross-rod,shaft, or pintle, H, has its ends located within the grooves g, and is adapted to move freely up and down therein. One or more sets of arms,l,are hinged on the pintle I-I, their opposite ends being pivotally secured to the outside faces of the doors F,.near their free edges. The arms I are preferably formed with two gradually-separating branches, as shown, each set consisting of a male and female section, constructed on the principle of the two wings of an ordinary door hinge or butt. A convenient number of these sets of arms is two, and they are preferably pivotally secured to the doors, by providing each of the doors with three pairs of perforated ears,t, and passing rods h through said perforated ears and through the perforated ends of the arms located between the ears. The arms I are constructed of such length that when the doors are closed the pintlc or shaft H will rest somewhat above the ends of the arms secured to the doors, and hence any pressure on the doors from within the hopper will have a tendency to slide the pintleHup- 1 described, and many slight changes might be wardly in' the grooves g. A rock-shaft, K,

is located between the girders B above the movable pintle H, and extends from the outside of the car about one-half the distance across it. It is journaled near its outer-end in a plate, L, secured to the side frame ofthe car, and at or nearits inner end in a depending standard or hanger, Z. The inner end of the said shaft K is provided with a crank, k, the wrist-pin of which is connected with the pintle H b'y'a rigid bar or link, M, loosely sleeved on the pintle and on the Wrist-pin. The outer end of the shaft K is provided with a spur wherl, N,with which a pair ofgravityi dogs, in and n, located on opposite sides of the spur-wheel and pivotall'y secured to the plate L, are adapted to engage. The dog a, which looks the shaft K against a rotary motion toward the left, or in a direction to allow the pintle H to rise and the doors to open, is

secured in engagement with the spur-wheel by means of a rotary arm, 0. The object of this is to prevent any accidental displacement of the dog m,from jarring or otherwise, when the car is in motion. By releasing the dog m from the wheel N the weight of the load pressing against the doors F will automatically cause the pintle H to move upwardly, and by means of the crank the shaft K will be rocked,the dog on following the teeth on the spur-wheel, and being ready at any moment to automatically lock the doors in open adjustment. When it is desired to close the doors after the load is discharged, the dog a may be disengaged from the wheel N, when the weight of the pintle H and arms Iwill to the doors through the crank it, pintle H,

and arms I, and they are thereby closed or Y 7 opened, as may be desired.

tlefrock-shaft, and crank might be employed It is evident that a separate movable pinfor each section of the hopper, and one door 'only be operated thereby, and that the rockshaft K might be extended across the car and provided with one or more crank-arms. The

' bottom of a car might also be separated into two or more hoppers,-similar to the one above resorted to in the form and arrangement of the several parts described Without departing from the spirit and scope of my invention; hence I do not wish to limit 'myself strictly to the construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a dumping-car, the combination, with a hopper, a swinging door adapted to close its mouth, a movable pintle, and operating-arms connecting the pintle and door, of a crankshaft connected with the movable pintle, and locking devices connected with the crankshaft, substantially as set forth.

2. In a dumping-car, the combinatiomwith a hopper divided into two sections by a crosspartition, a pair of doors hinged to the crosspartition, a vertically-movable pintle on' movable pintle and locking devices connectedtherewith, of one or more sets of branched operating-arms'hinged on the pintle and pivotally secured to the doors, substantially as set forth.

4. The combination, with the car-frame consisting, essentially, of the side rails, end

beams, central cross-girders, and central longitudinal girders, of the hopper-bottom, with its inclined sides and ends held together and to the framework by the metallic bands, and the doors hinged to the cross-girders and adapted to automatically open by the weight of the load and close by the weight of the movable pintle and operating-arm, substantially as set forth.

5. In a dumping-car, the combination, with a hopper, a door, and a crank connected with said door, of a spur-wheel connected with said crank, and devices engaging the spur- Wheel for locking the door in open or closed adjustment.

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