CAR-DUMPING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 481,968, dated September 6, 1892.

Application filed June 30, 1891. Serial No. 398,092. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS J. PHILLIPS, a citizen of the United States, residing atOttumwa, county of WVapello, and State of Iowa, have invented certain usefullmprovements in Oar-Dumping Apparatus, of which the fOllOW". ing is a specification.

My invention relates to improvements in car-dumping, in which cars loaded with mineral or other substances are brought to the earths surface on cages plying usually in the vertical shafts of coal and other mines; and the objects of my improvement are the automatic action of'the car, as follows: The locking of the car on the stage by automatic devices, the automatic movement of the car from the stage, the automatic return of the car to the stage, also such an adjustment of the machinery that the car will run off the stage in either of two opposite directions from the same level or landing, a superior device for moving the sliding bar back and forth by the use of two connecting-rods, and an improved latch-lifter. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 shows a plan view of a shaft with sections of track to conduct the cars to the ripple and with a car standing on the cage over one division of the shaft and the sliding bar to tip the track upon the cage. Fig. 2 is a vertical section of the shaft with the cage, a loaded car thereon held in position, and the entire cage and car elevated to the return point, ready to settle down upon its supports, and with the fiat bar thrown in to engage with the lug on the rail and tip it in its descent, also the inclined tipple-rail and latchlifter. Fig. 3 represents the same features shown in Fig. 2, the cage being lowered and resting upon its supports. Fig. 4 shows the loaded car moving toward the tipple. Fig. 5 is an end View illustrating the latch-lifting apparatus.

Similar letters refer to similar parts throughout the several views.

A is a vertical shaft sunk in the earth for mining or other purpose, and A the walls thereof, usually constructed of or strengthened by planks or other timbers.

A" is a twin shaft. (Partly shown in Fig. 1.)

I3 is the cage provided with two short parallel rails 12 1), upon which stands the car 0 on its wheels 0 0.

Attached to the floor of the cage B is an elliptic spring D, provided with a dowel d, adapted to receive a dowel-pin d, which is attached to and depends from the car 0.

The rails 11 b, which may be attached together, rest on the floor of the cage and are provided on their under sides at each end with suitably -attached lugs E, projecting downward through the floor of the cage, usually about three inches, and are also provided with longer lugs F, riveted to the bottom of the rails, as shown in Fig. 1, to prevent the endwise shifting of rails b b when inclined or tipped. Instead of the two lugs E E, a single lug may be used, and this may be placed on a connecting-bar between the rails 11 b or upon one of the rails only, but I prefer to use the two lugs, as shown in the drawings.

Movably attached to the walls of the shaft are four hinged posts or wings G, so loosely adjusted at the top by chains 9 that the rising cage will brush them aside in passing,but so hung as to swing outward automatically to intercept and thus stop the cage in its descent at a point on the level with the surfacetracks.

Upon the end of the car 0, and swung from a rod or support l1 by the iron strap-hinges h h, is a door I, provided with a latch t 1;, piv oted at 'i' to be automatically lifted to open the door of the car in its progress to the tipple J by the latch-lifters jj. The tipple J is composed of two short rails J, attached to a platform or similar support and so curved at the outer end as to receive the forward wheels and stop the car. Fastened to its curved points are the latch-lifters jj, before men-' tioned. The center of the tipple is supported bya shaft L,journaled at either end in boxes Z, and is adapted to be tipped by the weight of the car, as hereinafter described.

On the opposite side of the shaft from the tipple J and in line with the rails b b are two rails M M, forming a section of track, onto which the car may be run, if desired. These rails M M are attached to a fiat bar N, adapted to be moved laterally by the connecting-rods cage F rest on the hinged supports G.

N, only one of which is shown connected, the other connecting-rod N occupying alike position on the opposite side of the twin shaft A". The rails M M on the flat bar N are adapted to be thrust under to tip the rails on the cage, and for this purpose the bar N is connected with the rock-shaft P by the rod N in such a way that the rails M M may be advanced at will to tip the rails 19 b or withdrawn to form part of a continuous track to the floor of the dump-house. This bar rests on suitable bearings O O to allow it to have a reciprocating motion at the will of the operator through the lever P, rock-shaft P, and short rods 19 on the opposite side of the shaft, which are connected with the bar N by the connecting-rods N N.

In the operation of unloading coal by my mechanism the method is as follows: The cage 13, with its car C, is first lifted up the shaft above the level of the sections of track. As the cage passes the hinged posts G they immediately swing out into the position shown in the drawings in readiness to receive and stop the cage in its descent. If the operator then desired to shunt or propel the loaded ear upon the tipple, he moves the lever P and throws the flat bar N forward until its rails M M are thrust under the track-rails b b in position to intercept and tip them on the descent of the cage. The cage is now lowered until the lugs E E on the rails b b are intercepted in their descent bythe rails M M, attached to the bar N in a way to tilt the endsof the rails 11 b, as shown in Fig. 3. The cage is now still further lowered until the spring sinks away from the carand the dowel d in the spring is disengaged from the dowel-pin cl and the corners of the The car is thus left standing on an inclined track and disengaged from the locking of the spring and its dowel, as shown inFig. 3. From this position it is now automatically impelled downward on the inclined track toward the tipple J by gravity and is carried by the momentum of its descent up the slightly-inclined tipple-rails until it reaches and is stopped by the curved outer ends of the rails J. As the car nears the curved ends of the rails the latch I is automatically lifted by the latchlifter jj. The door thus freed from the restraint of the latch is swung open by the pressure of the contents of the ear and the jolt of the collision of the car against the curved carstops J. The car swings on the tipple in the usual manner and the load is discharged through the open door of the car. To secure the automatic return of the car from the tipple, the tipple-railsjj are also, as previously mentioned, made to incline toward the shaft when the tipple is in its untipped position, as shown in Fig. 4. The car is returned to its horizontal position on the tipple by gravity and now stands on the inclined plane of the tipple-rails as it previously stood on the inclined rails Z) Z); but the track on which it stands is now inclined toward the cage instead of from it. The rails M M are withdrawn from beneath the lugs E E, allowing the rails h b of the track on the cage to drop down upon the floor of the cage. The car now occupies a po' sition above the level of the track on the cage and is returned by its own gravity down the inclined track and is carried forward by its momentum and run upon the cage, depressing the spring D until the dowel d receives the dowel-pin d, which effectually and automatically locks the car upon the rails of the track on the cage. When it is desired, as is often the case, to remove the car from the cage on the opposite side from the tipple to run it elsewhere, the lever P remains stationary. The rails M M are not advanced, as shown in Fig. 2, and do not engage with the lugs E E, and the cage is lowered at once upon the wings Gr in such a position that when the spring D is depressed by the foot of the operator releasing the dowel cl from the dowel-pin d the car can be moved from the cage. The rails M M, being now in line with the rails b b on the cage, form a continuous track, allowing the car to be removed on the floor of the du m phouse or elsewhere on substantially the same level as the tipple.

IIeretofore in using a self-clumping car placed on a cage it has been impossible to remove a car on the opposite side from the tipple and on substantially the same level therewith, owing to the fact that the device used for elevating the rails on the cage would not allow the car to pass off from the cage after the rails had returned to a horizontal position while the cage rested on the wings G. This necessitated a second set of Wings below or above the wings G and also necessitated a second landing, both of which by using my device are unnecessary.

To obviate the necessity fora second set of wings and a second landing in order to unload or run oil? a car in any other direction than in the direction of the tipple, I employ the herein-described devices.

I consider this device of great value, as it avoids the expense and inconvenience heretofore incurred of duplicate landings and tracks.

I do not claim, broadly, the tipple herein shown, nor, broadly, the mere device for tipping the rails of the cage by interposing a prop under one end of the rails in their deicent, as I believe these features are both old;
