To cir/ZZ whom, it may concern:

Be it known that I, WILLIAM HENRY HOL- MAN, a citizen of the United States, residing at Durango, in the county of La Plata and State of Colorado, have made certain new and useful Improvements in Dumping-Cars, of which the following is a specifica tion.

My invention is an improvement in dumping-cars, and has for an object to provide a novel construction for securing the car in place on the truck and for securing the door or gate of the car; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure l is a perspective view of the car with the parts in position to receive the load and to transport it to any desired point; and Fig. 2 shows the car in dumping position, with the gate released, in dotted lines. Fig. 3 is a detail view of the upright shaft. Fig. 4 illustrates the bearingbrackets in detail. Fig. is a detail View of the depending guide -plate attached to the front end of the car. Fig. 6 is a detail view of the truck-plate of the car, and Fig. 7 is a detail view of the latch-bail.

The body A is hinged at A7 to the truck B and s provided with the -end-gate O, which is hinged at O' at its upper edge, so it can swing open at its lower edge when released by the operation of the latch presently described.

The latch D is in the form of a bail, having the side bars D and the end bar D2. The side bars extend alongside the body A, are pivoted at d thereto, and have their fre'e ends d2 hooked to engage with the projections O2 on the end-gate O, suitable guides d3 being provided for the side bars Dl near their rear ends. The bail extends slightly in advance ofthe body A, with its front bar extending across the front of said body, so the bail can be rocked on the pivotal connection of its side bars with the body A to adjust its catches into and out of engagement with the end-gate.

The truck B is provided with a plate B', having a slot B2 for the lower end of the guide plate E, which is secured on and depends from the body A at the front end of the latter. This guide-plate is provided with a bearing B3 for the upright shaft F, and

Serial No. (39;262. (No model.)

brackets 1A and 2 are secured on the body to serve as bearings for the said shaft. The shaft F is thus journaled so it can be rocked and is provided between the bearings l and 2 with a handle-arm F', and the bearing 2 is provided with notches 4, by which the handlearm may be secured to hold the shaft in any desired adjustment. At its lower end the shaft F has a crank-arm F2 to engage with the truck in order to hold the body in position on the truck until it is desired to dump the same. The shaft F is also provided with a crank-arm F3, which lies under the front bar D2 of the bail-latch and secures such latch normallyin the position showngin Fig. l. The plate B' of the truck is preferably recessed at B3 to receive the shaft F and facilitate the adjustment of the crank-arm F2 into engagement therewith. In practice the crank-arms F2 and F3 are so related to each other that the arm F2 will be adjusted out of engagement with the truck before the arm F3 is adjusted clear of the baillatch. Thus in the operation of the invention the upright shaft,which may be termed the main controlling-shaft, may be turned partially from the position shown in Fig. l to free the crank F2 from engagement with the truck, so the body can dump, and may then be further turned to clear the bail-latch, so the latter can be operated by moving its front end downward over the crank F3, as shown in dotted lines in Fig. 2, to release the end-gate and let the latter swing open to discharge the contents of the body A. It will be noticed that the bail not only operates as a latch,but also forms a convenient handle for thecar.

By my invention it will be noticed I secure a simple and effective dumping-trip and door ICO vided with a guide-slot, the body jointed 'to the truck and provided with a dumping-gate at one end, the bail-shaped latch having its side bars pivoted to the body, its free ends arranged to secure the gate and its front bar extending across the front of the body, and the upright main shaft journaled on the front end of the body and provided With crankarms for operation in connection with the truck and the front bar of the bail-latch, and the guide-plate secured to the body and operating in the slot of the plate secured to said truck all substantially as and for the purposes set forth.

'2. The combination of the truck, the body jointed to the truck and having a dumpinggate, a latch for securing the gate and a detent device by which to secure the body to the truck and the latch in engagement with the gate substantially as set forth.

3. The combination With the body having a dumping-gate at one end, of a bail-shaped latch having side bars pivoted to the body and arranged to secure the gate and having a front bar extending across the front of the car whereby the latch may serve as a handle for the car substantially as set forth.

4:. The combination of the truck, the body jointed to the truck and having a dumpinggate, the latch pivoted to the body and arranged to secure the gate and having a bar extending across the front of the body, and the main shaft having a crank-arm for securing the body to the truck and a crank-arm for engagement with the front bar of the latch for holding the latter in position to secure the gate substantially as set forth.

5. The combination substantially as described of the truck provided with a plate having a guide-slot, the body jointed to the truck and having a guide-plate operating in the slot of the truck-plate and means inde pendent of the said guide devices for seci- 1 ing the body of the truck substantially as set forth.

described of the truck, the body jointed to the truck so it can be adjusted to dumped position and provided with the end-gate, the bail-shaped latch having its side bars pivoted to the body, its free ends arranged to secure the gate and its front bar extending across the front of the body, and the upright main shaft journaled on the front end of the body and'provided With means by which it may be turned and With crank-arms one of which is arranged for adjustment to secure the body to the truck and the other in position to engage With the front bar of the bail-latch to secure the latter in position to hold the gateY substantially as set forth.

8. The combination with the truck the body jointed thereto and provided with the dumping-gate and the latch for securing the gate, of the detent carried by the body and having portions for securing the body to the truck and for securing the latchin position to hold the gate and arranged for operation to successively release the body from the truck, and the latch substantially as set forth.
