T0 all whom t may concern:

Be it known that I, DANIEL KING, a citizen of the United States, residing at Pinkney, in the county of Lawrence and State of Tennessee, have invented certain new and useful Improvements in Dumping-Cars, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to dumping-cars for carrying and unloading coal, slag, gravel, or o-ther material which is desired to have dumped in bulk. i

The object of the invention is to produce a side-dumping car having side doors or gates which open when the car swings and to operate the dum ing by spring-power, the power.

beingl store in the springs when the carbody is brought to horizontal position; also, to construct attachments by Which the movement of the train may release the body and door and yalso may right the dumped car and store up power in the springs for future dumping g also, in various improvements in the construction of dumping-cars, substantially as hereinafter described and claimed.

. Figure 1 is a plan view of the truck, the truck-frame, the body-frame, the body and door locking andoperating system, and the door-pintles and their connections, the carbody, lining, and doors being omitted for clearness of illustration. The operatingcams, obstructions, or inclines at the side of the track are indicated. Fig. 2 is an end view of the car with dumping-lever extended and post at the side of the track in position when the car is about to be unlocked for 0'. Fig. 3 is a section through the car-body, showing the same in dumped position and means for restoring the body to horizontal position as the-train progresses.

The truck A is preferably of the general character of the truck described in my Patent No. 792,660, of June 20', 1905. The body B rocks sidewise on the longitudinal axis C, as in said patent.

For convenience of illustration I illustrate and describe only the lever system for dumping the car -body at one side of the track. It will be apparent to the skilled mechanic that the system can be readily duplicated in such parts as would be necessary to make the device operable from either side and to cause the car to dump at either side of the track.

The numeral 1 indicates the dumpingsprings. These springs have their lower en s secured to the draft-beams of the truck and their upper ends fast to the body-beams or body-frames D, any suitable connection bel ing used.

The body is normally held in'its central or horizontal position by locking pins or bolts 16 which bolts are normally pressed inward toward the middle of the car by springs 61, as in my atent referred to. A lever 15 at either en of the car and extending across the car withdraws one or the other of the bolts 16, according to the movement of said lever. -Thus when either lever 15 has its end on one side of the car pressed toward the car center the pivot 66, connecting said lever to bolt 16 at that side, becomes a fulcrum for the lever and the corresponding bolt at the other side is withdrawn, permitting the carbody to tilt in the direction of the bolt so withdrawn, as explained in said patent. This the car-body will do under the impulse of spring 1. The levers 15 are operated simultaneously by means about to be described. Rods, links, or chains 17 are connected to projections from levers 15 andare coupled to levers 2, extendin about transversely of the car and pivote to the under body-frame D at 71, substantially as shown in Fig. 1. when either lever 2 is swung on its pivot 71 the train of links and levers described will be operated to liberate bolts 16 at one side of the car, thus permitting springs 1 to dump It will thus be apparent that.

the car. 'Lever 2, at one side of the car at l least, has a knuckle-jointed or hinged extension 2A, which can be folded inward, as in dotted lines, Fig. 1, or swung out, as in full lines, Figs. 1, 2, and 3, and when so swungy outward it is apparent that the contact of its outer end with a fixed obstacle alongside the track when the car moves would have the same eifect as a movement of the lever with `the car standing still-that is, such an ob- IOO . bankment, &c.

effected as follows: The car-doors E are the side of the car-body and extend from end to end. At each end each door has a pintle 18, which pintle rests in a groove in a door-lever 14, which door-lever is pivoted, as at 41, outside the body and to the end F thereof, the pintle 18 normally passing through a notch 44 in the end F of the car-body. The inner ends of the door-lever 14 are connected by tension-springs 3 to the bottom or lower edge of the car-body. Between the pivots 41 and the pintles 18 a chain 4 connects each doors-lever with the locking-lever 15, the chains passing under suitable pulleys 42 near the lower corners of the car-body. locking-levers 15 are drawn back on the dumping side ofthe car they slack the chains 4 on that side, thus .permitting springs 3 on that side of the car to pull down the door-levers when unlocked. The doors E have catches 10, which extend downward from the doors into notches in the bottom frame D of the car-body, and preferably these catches have hooked ends. The locking-levers 15 have inturned ends 9, which hold the catches rmly into place in said notches when said levers are locked. When these locking-levers 15 are unlocked, (dotted lines, Fig. 1,) they permit the ready escape of the catches 10 from said notches. Thus the movement of levers 15 simultaneously unfastens the catches 10 and permits the springs 3 to-lift the outer ends of the doorlevers on the dumping side, while the springs 1 tilt the car-body toward that side. The inward movement of levers 15 at the side of the car remote from the dumping side simply draws down the door-levers at that side .against the tension of their springs, (by means of chains 4;) but as the pintles 18 remain in the notches 44 in the ends of the carbody this door is not unfastened. The lever 2A is generally swung back to ltrip the -locking-levers, as described, by engagement with a short post 5 at a tipple, a high em- Preferably post or obstacle 5 will be pivoted near its base, as at 5A, and will be held upright by a spring 5B. As the car tilts the lever 2A will swing above the top of post 5 or the post will yield, or both movements will take place, so that lever 2A will be free. Of course the manipulation of lever 2A may be effected by hand where force enough is employed.

After the car-body has been dumped it can be restored to horizontal position by the engagement of lever 2A with a downwardly-inclined surface 6 at the side of the track, said incline being arranged to bear down on the outer end of the lever 2A as the trainmoves along. The outer end of the lever 2'A has an antifriction device to engage with the mechanism alongside the track. Thus when the body is tilted a roll 12, supported on suitable bearings at the end of said lever, engages As the the under side of the inclined surface 6 and rolls down under said incline as the car advances, which of course depresses the outer end of said lever 2A and causes the car-body to be swung back to horizontal position. The incline 6 will be supported on suitable posts, as 6". When the car-body has been restored to its horizontal' position, the hingelever 2A may be turned in toward the carbody and automatically locked by engagingv an inwardly-extending incline 7, suitably arranged alongside the track. The antifrictionroll 13 should project from the lever, so as to engage this incline 7 when the train reverses its movement. When the lever 2A is swung inward, it may be held by catch 88.

In the illustrations no attempt has been made to indicate the parts as drawn to scale, and parts not considered essential for an understanding of the case have generally been omitted.

What I claim is 1, A dumping-car provided lwith a spring interposed between the body and truck and held under tension when the car is in horizontal position, means for holding the car-body horizontal, and means for releasing the body so that the spring may dump the same.

2. The combination with a car-body and supporting-truck, of a spring interposedbe# tween the body and truck, means for holding the body horizontal and the spring under tension, means for holding a side door closed, and means for releasing the body and door, whereby the spring effects the tipping of the bodyv and the opening of the door.

3. In a dumping-car, the combination with the car-body, of body-locking levers at the ends thereof, door-levers on which the doorpintles rest, springs `connecting the ends of the door-levers to the body, and chains connecting the door-levers to the body-locking levers, whereby the release of the body-locking levers releases the tension on the springs connected to the door-levers.

4. In a dumping-car, the combination with the car-body, of' door-levers ivoted to said body, doors supported by said levers, and a spring connecting one arm of each of the doorlevers to the body, and serving to lift the doors when permitted to operate on the door# levers.

5. In a dumping-car, the combination of a car-body and locking-levers therefor, a pair of door-levers at each end ofthe car-body, springs connected to the inner ends of these levers and to the car-body, doors supported to the outer ends of said door-levers, and body-locking levers connected by fieXible connections to the door-levers, to hold their springs under tension when the body is locked.

6. The combination with a dumping-car body, of a swin ing door supported on doorlevers, bodyloc ringlevers by which the body is held in horizontal position, and door- IOO IOS

catches also engaged by said body-locking levers. 4

7. The combination with a dumping-car truck and body -locking levers extending transversely of said body, door-levers at each end of the body and having pivots at each side which become alternately the ulcrum of said levers, doors havin pintles extending into notches in the doorevers and also into notches in the body, s rings connected to the body and to the doorevers, and iexible connections from the door-levers to the bodylocking levers, whereby the latter may be depressed and the doors left supported by the ody, as set forth.

8. The combination with a car-truck and dumping-body, and an interposed spring, of a lever connected to the body, and an incline adjacent to the car-track, whereby the carbody may be brought to horizontal position and the spring placed under tension as the train moves past the incline.

9. The combination with a car-truck and dum ing-body, and a spring acting to dump the ody, of means for holding the body in horizontal position, and means alongside the track whereby the car-body may be released and permitted to be dumped by the spring.

10. The combination with a car-truck and car-body, and a spring acting to dump said body, of detents acting to hold the body in horizontal position, a'hinged lever which may be extended at the side of the car and act to release said detents by engaging an obstruction, and an incline at the side of the track by which said hinged lever is turned in as the car moves.

Il. The combination with a car truck and body, of ay spring acting to dump the body when free to do so, a swinging door on said body, levers on which said door may swing, and springs connected to the door-levers and body to support the doors when swung open.

In testimony whereof I aiiix my signature in presence of two witnesses.
