tents of cars.

It has heretofore been proposed to dump coal from cars into large buckets and to provide means for distributing the car-load of coal simultaneouslyin several buckets. Such apparatus has operated successfully to distribute the coal evenly among the several buckets, because the car from which it was dumped was filled evenly from end to end, and therefore the coal flowed at a uniform volume from the car throughout its entire length. In the employment of what are known as gondola cars, such as now in common use for transporting ore, it has been found necessary to so load them that the maximum weight shall be removed from the center of thecar and made to come more directly over the trucks. This is because such cars are not of suflicient stability to withstand the great weight of ore at a point centrally between their ends. Cars loaded with ore in the manner above indicatedviz., so that the load will be disposed at respective sides of the center of the car and each portion of the load will havea center of gravity between the center and one end of the carcannot when bodily dumped be evenly distributed among a series of buckets by means of the fixed distributing devices heretofore em- WVhat are known as hopper-cars are used quite extensively for transporting ore, and with these the center of gravity of the load is coincident with that of the car. These cars are built to withstand considerable weight, are much shorter than gondola cars, and are usually completely'filled. When a hopper-car is bodily inverted to discharge the contents be placed quite close together, and this is neither practicable nor feasible-no more so than to separate them in pairs, as would be necessary to receive ore dumped from gondola cars. It is therefore important that some means be provided for insuring an equal distribution of ore as it is being dumped from the car into buckets placed at predetermined distances apart, regardless of the kind of car employed or the manner of loading.

It is one object, therefore, of my present invention to provide means for adjusting the distributing devices in accordance with the disposition of the load or ore in the cars, so that the even distribution of the ore among a series of buckets will be insured when the car is bodily inverted.

A further object is to provide means for adjusting the distributing devices of a cardumping apparatus and holding the movable parts of such distributing devices rigidly in the position to which they may be adjusted.

With these objects in view the invention consists in the combination, with means for inverting a car and an apron on which the load is discharged, of fixed distributers on said apron for deflecting the material into several buckets and adjustable deflectors cooperating With said fixed distributers to insure the even distribution of the material to the several buckets regardless of the character of car being used and the disposition of the load therein.

The invention also consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figures 1 and 1 are elevations illustrating my invention. Fig. 2 is a face view with some of the parts removed, showing a car inverted to discharge its contents into a series of buckets, and also showing the distributingdevices in perspective. Fig. 3 isa face view showing the appliances for manipulating the adjustable deflectors; and Figs. 4 and 5 are edge and end views, respectively,of the appliances for operating the deflectors.

A represents an upright framework or tower provided at points between its top and bottom with horizontal forwardly-projecting braces 1, the free end of each of which is connected with the upper and lower portionsof the frame or tower by means of diagonal braces 2 3. The braces 2 3 are connected together and with the free end of the horizontal brace 1 by means of a suitable coupling 4, and to each of said couplings the upper end of a post or upright brace 5 is secured, the lower end of which rests on a suitable base. Posts 6 pro-' ject upwardly within the front portion of the frame or tower and serve to pivotally support a cradle B, the rear end or edge of the latter being normally supported by short posts 7 in the frame or tower. The cradle 13 comprises a base 8, provided with tracks mounted on a movable platform 8 for the accommodation of an ore-car A, and a normally-upright apron 9, pivotally connected with the posts 6 and projecting a distance above the same. The ends of the apron are beveled, and coincident with these beveled ends diagonal flanges project at right angles to the face of the apron and constitute fixed deflectors 10 to assist in the distribution of the ore discharged from the car when the cradle is tilted-t0 invert the latter. At the free end of the apron the ends of the flanges or deflectors 10 are connected by abeam or girder 11, and another beam or girder 12 is secured to the free end of the apron itself. Between these beams or girders the outer or forward ends of V-shaped fixed distributers 13 14 l5 are secured, said distributers being disposed on the face of the apron, and each member of each distributer is provided at one edge with a flange 14$, lying against the face of the apron and bolted thereto. At the apex of each V-shaped distributer 13 15 a shaft- 16 is mounted and passes through the apron, and for each of these shafts a bearing-sleeve 17 is provided and braced by means of bars 18, extending therefrom to the beam or girder 11, to which they are securely bolted.

An adjustable deflector 19 is secured to each shaft 16. These deflectors constitute an important feature of my invention and enable me to insure the even distribution of ore from the inverted car to a series of buckets 20, placed in certain predetermined positions and regardless of the character of the cars employed and the manner of loading the same. The buckets 20 are carried on suitable trucks 21, and it is 'very desirable and, in fact, quite necessary in the practical operation of transferring ore from cars to buckets, when the cars are inverted for this purpose, that the trucks and the buckets thereon shall be always placed in the same position with respect to the apparatus. Without the provision of the adjustable deflectors 19 this could not be accomplished because of the difierent kinds and sizes and lengths of cars employed for carrying ore and the different methods of loading the cars. Thus when a gondola car having its load of ore divided between its ends is inverted to discharge such divided load a comparatively-small quantity of ore would flow into the central buckets of the series, while the end buckets would be overlooked if some means be not provided to operate in conjunction with the fixed distributors to regulate the even distribution of the divided load to all the buckets of the series.

When a hopper-car is used, it is apparent that when it is inverted and its contents made to flow over an apron having only the fixed distributers the conditions above described would be reversed and the major portion of the ore would pass to the central buckets of the series and they would quickly overflow, while the end buckets would receive little or no ore. By means of the deflectors 19 all of this inconvenience can be avoided by adj usting said deflectors according to the disposition of the load in the car being dumped' that is to say, when gondola cars having the load in two sections at respective sides of its center are being dumped the adjustable distributors will be so disposed as to cause an amount of ore to enter the central buckets of the series equal to the amount passing to the outer buckets. When a hopper-car is dumped, the deflectors 19 will be moved to a position opposite to that which they occupied for a gondola car, so as to distribute the ore in such manner as to cause the same amount.

to enter the outer buckets as. flows to the inner or central buckets of the series.

The contents of the cars will be discharged (whether they be of the gondola or the hopper type) by inverting them, and this will be accomplished by turning the cradle or its pivotal support by any suitable means, and any approved devices (not shown) may be employed for holding the car in place on the cradle. It is desirable to provide means for preventing the cradle from being tilted farther than is necessary and for supporting the weight of the cradle and its load (should the latter not be promptly discharged) when the cradle is inverted. For this purpose I employ a series of posts 21.

It now remains to describe the construction and operation of the appliances for manipulating and locking the adjustable deflectors. The shaft 16 of each deflector 19 is extended beyond its bearing in the apron and provided with an arm 22. The arms 22 of the respective deflectors are connected, respectively, with the arms a of bell-crank levers 23 24 by means of rods or pitmen a a Rods or pit men 25 are connected at one end with the arms I) of the bell-crank levers 23 24, and the other ends of said rods or pitmen are connected with the respective ends of a sliding crosshead 26. The cross-head 26 is mounted on suitable guides on a bed 27 and is secured to a piston-rod 28. Cylinders 29 30 are located at the respective ends of the bed 25, and into these cylinders the respective ends of the piston-rod 28 project and are provided with pistons within the respective cylinders. The cylinder 29 is intended to receive steam for moving the piston 31, and thus transmitting motion through the system of rods and levers above described to the adjustable deflectors to move them in one direction or the other for the purpose hereinbefore fully explained. To control the admission and exhaust of steam from the cylinder 29, a suitable valve 33 is provided.

The cylinder 30 is intended for the reception of Water, and the flow of the water from one end of the cylinder to the other is controlled by means of a valve 34:. When both Valves 33 3% are open, the piston-rod will be moved in one direction (according to the position of the valve 33) by steam entering the cylinder 29, and the piston therein will move in the cylinder 30, displacing the water therein and causing it to flow from the end of said cylinder in front of the piston and enter the end of the cylinder behind the piston. During this movement of the piston-rod motion will be transmitted to the adjustable deflectors, as before explained. When the deflectors 19 shall have been properly adjusted, both valves 33 34 will be closed. The result of thus closing the valves will be to stop the movements of the deflectors and at the same time close communication between the respective ends of the hydraulic cylinder 30 and prevent movement in either direction of the piston therein, the piston-rod 28, and the connections between the latter and the adjustable deflectors 19. The deflectors 19 will therefore be locked in the positions to which they may be adjusted.

In order that the valves 33 34 can be manipulated without interfering with the cradle by which the cylinders 29 30 and connected devices are carried,it is necessary that the valverod shall be coincident with the fulcrum of the cradle. For this purpose the pivot-pin 35 of the cradle is made tubular, and through it a longitudinally-movable sectional valve-rod 36 passes. One end of the rod 36 is connected with one arm of a bell-crank lever 37, and the other arm of the latter is connected with both valves 33 and 34, so as to operate them simultaneously. The other end of the longitudinally-movable rod 36 is connected with one arm of a pivoted lever 38, and with the other arm of the lever 38 an operating-lever 39 is connected through the medium of a link 40.

From the above it will be seen that by operating the lever 39 the adjustable deflectors can be made to assume any desired angle and be locked in such position.

Various slight changes might be made in the details of'construction of my invention without departing from the spirit thereof or limiting its scope, and hence I do not wish to limit myself to the precise details herein set forth.
