Application filed August 1 1906. Serial No. 328.706.

To all whom it may concern:

Be it known that I, HUGH EDWARD Mme PHY, a citizen of the United States, residing at Oroville, in the county of Butte and State of California, have invented new and useful Improvements in Dump-Cars, of which the following is a specification.

My invention relates to improvements in railway dump-cars. Its object is to provide a sim le, strong, practical dump-car for use in rai way construction and elsewhere which shall occupy less room and be more easily and economically handled than the dumpcars now in use and which will ermit the dump being made with equal acility at either the side or the end of the car.

The invention consists of the parts and the construction and the combination of parts, as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure 1 shows the car in side-dumping position. Fig. 2 shows end-dumping position.

A represents a wheeled truck of suitable construction, and 2 is the box, swivelly mount ed thereon in suitable fashion and is of such construction as to permit it to be turned horizontally in any direction'to permit it to be loaded from any side and to be discharged from any side The box and its manner of mounting on the truck form the essence of mv invention.

The box is'preferably of boiler-iron, and its size depends on the character of the work for which the particular car is intended. The box is in the form ofan inclosed chute, open at top and bottom, with a removable closure 3 for the bottom, the chute bein bent approximately in the middle to provi e a downwardly inclined leg or portion 2' on one side of the pivot of the chute on-the truck and an upwardl -projecting leg or ortion 2* on the other sidb of the pivot. T e box is open at the top for loading, and the portion 2 overhangs the truck snficiently to allow discharge to The angle included between the parts 2 2 of the box is in actual practice about one hundred and twenty degrees, more or less, with the upper art 2 standing at a sli ht incline backwar from the perpendicu ar for the urpose of afiording proper balance.

T e tail-gate 3, which 1s removable for dumping purposes, is of any appropriate debe made conveniently at either the K sideor end of the car.

sign and is held in closed position by any suitable means. 'I have shown the gate as hinged at the top and held normally closed by the pivoted s ring-actuated latch members 3, engageab c with the keeper members 3* on the gate.

While the box may be mounted in any suitable fashion to have the proper swivel movement, I prefer the following construction: A. short vertical pivot-post dis secured to the under side of the box proximate-to the angle. This post has an annular bearingfiange 5 near its juncture with the box. The post is turnable and supported in a suitable socket member 6, secured centrally to the truck-bed. The socket member preferably consists of a cylinder havin a bottom flange 7 countersunk into the true r-bed andbolted thereto and having a to flan e 8, of steel or cast-iron, which forms a road caring for the flange 5 on the post. Three, four, or more brace-rods 9 support the. cylinder and box rigidly on the truck.

If desired, a platform-space 10 may be left at each end of the car, on which heavy rocks ma be piled.

be trouble with the dump-cars commonly in use in practical railroad constrnction wor is that they are too heavy and bulky and too large to work more than one at a time in an ordinary eighteenfoot cut. If they have onl a side dum it is necessary often to bui d out 'specia trestles. With my construction it is possible to Work two cars, each of thesan'ie capacityas the old, in an eighteen-foot cut to turn the box any way to allow it to be loaded from any side and to permit it to be dumped from the side or end. This side and end dump is an important item in many forms of work to which a dump-car is ut. The cariseasily moved about, making.

it especially handy and economioai of power in mountainous country, andit has very few parts to wear out or break. The construc- I tion of the box and its manner of mounting equalizes the weight on the running-gear when loaded. When roperly balanced, it can be easily turned by Having thus described my invention, what I claim, and desire to secure by Letters Patout is 1 The combinationwith a wheeledtruck, of a box in the form of an inclosedchute, open at top and bottom and bent approximately in the middle to provide a downwardly-inclined portion, a removable closure and in any direction.

for the lower end of said inclined p0rtion,.-

and a vertical pivot arranged substantially in the vertical plane of the angle included between the bent portions of the box, about Which pivot the box is horizontally turnable, substantially as described.

2. A dump-car comprising a .wheeled truck, and a swivelly-mounted box thereon, said box having front and back walls inclosing an' angular space of approximately one hundred and twenty degrees, the upper leg of the box arranged nearly vertical and open at the to and a removable'closure for the bottom 0 the box.

3. A dum -car comprising a wheeled truck, --a cy indrical socket-piece secured thereto in upright position, said cylindrical socket-piece having top and bottom flanges, the bottom flange bolted to the truck, braces connecting the top flange and truck-bed, an angular box having a pivot-post seating in said cylinder and provlded with an annular flange to bear on the top flange of the cylinder, said box open at the top and having a removable closure.

4. A dump-car comprising a wheeled truck, and a box pivotally mounted thereon, said box in the form of an inclosed chute open at top and bottom and bent centrally to have a lower downwardly-inclined portion on one side of its pivot, and an upwardly-extending portion on the other side of said pivot, said chute having a closure for its lower end, and said chute arranged to swing in a horizontal plane to discharge at the side or rear of the truck.

In testimony whereof I' have hereunto set my hand in presence of two subscribing witnesses.
