DUVIPING-*CAFL SPECIFICATION forming part of Letters Patent No. 634,874, dated October 1'7, 1899.

Application filed June 7,1899. Serial No. 719,678. (No model.)

. T LIZ whom, 'it may concern:

Beit known that I, ROBERT E. BROYLES, a citizen of the United States, residing at Chattanooga, in the county of Hamilton and State of Tennessee, have invented certain newand useful Improvements in Dumping-Cars, of which the following is a specification.

My invention relates to that class of dumping-cars which are provided with hopper- 1o shaped bottoms or pockets for holding coal, ore, and the like and which are also provided with doors which may be opened to deliver the contents of the car and may be closed and locked when it is desired to till the car with i 5 material to be transported. l-Ieretofore complicated mechanism has been employed for opening and closing` the doors.

The object of my invention is to provide simpler mechanism for this purpose.

I may construct the body of the carin any well-known way, and I provide each door with a sliding bolt which is operated in an improved way by a hand-lever, and each door is provided with a foot-lever by which it may be closed.

In the accompanying drawings, Figure lis a bottom plan view of a dumping-car embodying my improvements. Fig. 2 shows a transverse section on the line 2 2 of Fig. l. Fig.

3o 3 is a perspective view showing details of my improved devices for opening and closing the doors. Figs. 2 and 3 are on a larger scale than Fig. l.

The body A of the car may be of any usual construction and may be mounted in any approved way. The car shown is provided with a series of hoppers or pockets B. These may be of any desired shape, width, and length, and each one of the pockets is provided with 4c a hinged door C, which opens and closes the bottom thereof. Each door is hinged at one of its edges c. When closed, t-he door is preferably arranged to enter a recess c/ in the bottom or mouth of the hopper, so as to lit snugly therein, as indicated at the left-hand side of Fig. 2.

Each door is provided with a sliding bolt D. This bolt is arranged to slide in the guidestraps E, secured to the bottom of the door,

5o and also to slide into and out. of a lockingstrap F, secured to the frame of the hopper.

By sliding the bolt properly the door may be locked or unlocked in the manner illustrated in Fig. 2. The outer end of each bolt-that is, the end next to the side of the car-is connected by means of a link d with a hand-lever G, which is pivoted at its inner end g to a bracket H, secured to the frame surrounding the mouth of the hopper. The link disjointed to the hand-lever G between the point g and the outer or handle end of the lever. Each door may be provided with one or more bolts of this character. One is snflicient when the doors are comparativelysmall, butwhere very long doors are used an additional number of bolts and operating mechanisms may be employed.

lach door is provided with a foot-lever I, which is secured to the door near its inner end-that is, the end opposite the hingeand it is of sufficient length to afford the requisite leverage and also to project to the side of the car when the door is opened, as illustrated at the right-hand side of Fig. 2. Then the door is opened, the attendant may by putting his foot on the outer end c' of the lever cause the door to be moved inward and upward, and when the door has been moved fully inward the llever G may then be operated to shoot the bolt. The foot-lever is not only secured to the inner end of the door, as before stated, but it is also connected therewith by means of a branching brace Aif', which is connected to the lever I, preferably at about one-third the distance from the inner end of the lever to the outer end thereof, and this bracing-arm is also connected at to the door between its central portion and its outer or hinged edge. By this means the lever is made sufficiently rigid so that when pressure is placed upon the lever the bracing-arm t Will take part of rthe strain and prevent the lever from being bent. This mechanism has been successfully used. It is much simpler than the complicated mechanisms before employed and operates with entire satisfaction.

-I claim as my inventionl. A dumping-car provided with a hinged door, a sliding bolt carried by the door, a

hand-lc ver pivoted to the car-body, and movable about a pivot parallel with the axis of the hinge of the door, and a link jointed to IOC the bolt and jointed to the hand-lever between its pivot and its outer end.

2. The combination of a car-body provided with a hopper, a door hinged at the mouth of the hopper, a sliding bolt, guide-straps on the door in which the bolt moves, a locking strap into which the bolt moves, a hand-lever hinged to the car-body and movable about a pivot parallel with the axis of the hinge of the door, a link jointed to the end of the bolt next to lthe hinge and jointed to the operating-lever between its hinge and its outer end.

3. The combination of a oar-body provided with a hopper or pocket, a door hinged thereto, a bolt for looking the door, a lever for moving the bolt, and a foot-lever attached to the door near its inner end and projecting at right angles therefrom to an extent suflicient to enable the attendant to close the door by his foot.

et. The combination of a ear-body provided with a hopper or pocket, having a hinged door, a sliding 'bolt carried by the door, straps on the door in which the bolt moves, a lock- ROBT. E. BROYLES.
