Application filed April 6, 1903. Serial No. 151,348. (No model.)

To all whom it may concern:

Be it known that I, GEORGE G. NEwooMB, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Ore-Oars; 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 refers to improvements in orecars such as are employed in connection with mines, quarries, and the like, and relates particularly to dumping means for such cars.

The object in view is the production of a car capable of being dumped in such manner as to permit the load being discharged smoothly and evenly and without bulging or distending the sides of the car, the load being free to move without any binding effect, while being readily timed in its discharge.

With this and other objects in view the invention consists, in combination with a suitable truck, of a car-body movably mounted thereon,a removable gate therefor, and means for automatically removing said gate relative to the movement of the car-body.

It further consists, in combination with a truck, of a car-body pivotally mounted thereon and formed with its discharge end larger in transverse section than the remainder of the body and a movable discharge-door for such end.

It still further consists, in combination with a suitable support, of a receptacle movably mounted thereon and provided with a discharge-door and tapering longitudinally and transversely to the lowest point of said door.

It also consists in certain other novel constructions, combination, and arrangement of parts, as will be hereinafter fully described and claimed.

, In the drawings, Figure 1 represents a view in side elevation of a car embodying the features of the present invention. Fig. 2 represents a similar view of the same, illustrating a car in its dumping position. Fig. 3 represents a front elevation of a car. Fig. 4 represents a rear elevation of the same. Fig. 5 represents a top plane View of a truck. Fig. 6 represents a top plane view of the car-body.

In the ore-mining art, and particularly in coal-mining, it is common to use oars having their bodies pivotally mounted upon the trucks and hinged in such manner as to be capable of being dumped in almost any direction from the truck; but in the use of such cars serious difficulty has arisen through the fact that in discharging the load the orebinds against the sides of the car and causes the same to expand. Of course the degree of expansion at each discharge may be comparatively small; butin the course of afew months the car sides become distended or bulged quite perceptibly and sometimes even to a number of inches, making the dumping more difficult and slow, besides shortening the life of the car. To overcome this difficulty and to facilitate the discharge of ore from an orecar, I contemplate employing, as seen in the accompanying drawings, a common form of truck 1, upon which is mounted a turn-table 2, to which table is secured a car-body 3 by means of suitable hinges 4, whereby said body iscapable of being pivoted in a horizontal plane and tilted vertically in any desired direction. As will be observed from a careful examination of Figs. 3, 4t, and 6 of the drawings, the body 3 is wider at its discharge or front end than at its rear end and the same is wider at the base of the rear end than at the top thereof, whereby said body flares side Webs or brackets 6 6, extending along the.

sides of the body 3, inclosing the same and being pivoted thereto, as at 7 7. Fixed to the table 2 and extending laterally therefrom are suitable arms or brackets 8 8, provided with eyes 9 9, to which are pivotally connected links 10 10, said links extending upwardly and pivotally engaging the webs 6 6, as at 11, the pivot-point 11 being spaced somewhat forwardly of the pivot 7, whereby the gate 5 will be retained in a vertical plane regardless of the position of the body 3.

Any suitable latch device 12 may be employed for normally locking the body 3 in its horizontal position.

In operation the car is dumped by first tripping the latch 12 and then tilting the body 3 upon its hinges 4:. By this movement of the bodythe gate 5 is caused to swing upon its pivot 7, the link 10 moving with the longitudinal movement of the body 3, but limiting the said gate 5 against vertical movement, whereby the said gate is caused to assume a position above the discharge end of the carbody. The tilting of the car-body 3 may be done gradually, and gate 5 will open in timed relation .to the movement of the car-body, whereby the load may be discharged at any desired speed, and owing to the particular shape of the car-body will be free from the danger of binding and injuring the walls of the car.

It will be observed that the particular wedge shape of the body is such as will permit of the ready discharge of contained material even though the walls of such body be slightly bulged or distended. In the loading of cars of the type above described it is common to fill the same from receptacles discharged above the car, and the impact of the discharge is liable to expand the side walls of the body;

but with my construction, even though the.

walls are slightly expanded, the load may be easily and readily dumped.

Although I have specifically set forth the details of one embodiment of the present invention, yet it will be understood that many slight alterations may be made without depart-ing in the least from the spirit and scope of the invention.

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

1. In a mechanism of the class described, the combination with a rotatably-mounted support of a car-body pivoted thereto formed with a discharge opening, a gate closing said opening, Webs formed on said gate inclosing a portion of said body and pivotally engaging the same, anda link connectingsaid rotatably-mounted support with one of said webs.

2. In a mechanism of the class described, the combination with a support, of a receptacle pivotally mounted thereon and formed with a discharge-opening, the walls of said receptacle flaring from all points to the point of discharge.

3. In a mechanism of the class described, the combination with a support, of a receptacle pivotally mounted thereon having an open, front end, the side walls of said receptacle flaring from the rear end thereof to the front end and from the upper edge of the receptacle to the bottom.

4. In a mechanism of the class described, the combination with a support, of a receptacle movably mounted thereon and formed with a discharge-opening, thewalls of said receptacle tapering in all directions away from the point of the discharge-opening.

5. In a device of the class described, the combination with a truck of a turn-table mounted thereon, brackets fixed to said turntable and extending laterally beyond the same, a receptacle pivoted to said turn-table and adapted to swing vertically between said brackets, a movably-mounted gate closing one end of said receptacle, and supports carried by the free ends of said brackets engaging said gate.

6. In a mechanism of the class described, the combination with a rotatably-mounted support of a receptacle pivota lly carried thereby, a gate closing one end of said receptacle and. provided with means pivotally engaging the receptacle, and supports carried by said rotatably-mounted support and engaging said gate for retaining the same against vertical movement.
