DUMPlNG-CAR.

SPECIFICATION forming part of Letters Patent No. 690,226, dated December 31, 1901. Application iiled October 30, 1901.` Serial No. 80,506. (No model.)

T0 @ZZ whont t mar/'concern- Be it known that I, RALPH BAGGALEY, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a oertain new and useful Improvement in Dumping-Cars, of which improvement the following is a specification.

My invention relates to dumping-cars employed for the transportation of minerals or other material over railroad-tracks; and its object is to provide a car of such character which may be actuated either automatically or manually to dump or discharge its load at a desired point and which shall be specially and desirably applicable to use in the automatic haulage and delivery system which is set forth in an application for Letters Patent led by me August 16, 1901, Serial No. 72,276.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a side view in elevation of a dumping-car embodying my invention; Fig. 2, an end view of the same; Fig. 3, a front or face view of a load-indicating signal appliance, and Fig. 4t a vertical section through the same and through a portion of the car-body to which it is attached.

The transportation of cars embodying my invention over arailroad-track 5 is in the system set forth in my application Serial No. 7 2,276,aforesaid, eected by means of an overhead endless wire rope or cable l2, which is carried over supporting-rollers in the ordinary manner, and the movement of the cable is transmitted to the cars by means of pushing-balls 14, which are secured at properintervals to the cable and Awhich abut against suitable bearings fixed to the cars. In the operation of the system of said application the cars are automatically dumped or unloaded at desired and determined points, and the dumping-car of my present invention, while specially designed for and particularly adapted to service under the conditions above indicated, may without substantial structural variation be employed with other means of propulsion and be manually instead of automatically unloaded.

In the practice of my invention I provide a dumping-car which accords in its general features of construction with ore or mine cars of the latest type now in service and is further provided with novel accessories, as hereinafter described. The body 17 of the car, which is preferably formed of stout sheet or plate metal and is rectangular in plan,is open at its top to receive its load and is supported on Wheels 55, each of which is preferably fixed upon an independent axle 56, rotating in an oil-box 57 to facilitate the passage of the car around curves. One of the sides of the carbody 17 is substantially vertical and the other side is vertical for a'short distance below its top, below which vertical portion it is downwardly and inwardly inclined, and is connected at its bottom to the bottom of the opposite side. The car-body is thus made of substantially triangular cross-section to enable the load to be quickly dumped or discharged by gravity when desired. The side of the carbody,which is vertical or nearly so, is provided with a lateral discharge-opening controlled by a discharge-door 5S, which is hinged to the upper portion of the car-body, so as to have the capacity of being swung outwardly therefrom by pins 59. The door is held closed by locking-bolts 60, tted to slide vertically in guides 6l, secured to the door and engaging sockets G2. The locking-bolts 60 are withdrawn from their sockets to permit aload to be discharged and returned to said sockets to prepare the car for the reception of another load byia tri pping-lever 63,which is pivoted by a piu 64 to the door and is coupled by a link 65 to ahorizontal bar 66, the ends of which are secured to the locking-bolts 60. Vhen the door is closed and locked, as shown in Figs. 1 and 2, the upper end of the tripping-lever pro- `iects outwardly fora sufficient distance to permit it to be struck and swung upon its pivot by one of asetof adjustable trippers 113, located adjacent to the track, (shown in dotted linesin Figs. l and 2,) its movement releasing the locking-bolts 60 from the sockets 62 and allowing the door to be pushed open by the load to discharge. When the door is open, the tripping-lever stands in a substantially vertical position, so as to pass a tripper or trippers Without being brought into Contact therewith. After the discharge of a load the door is closed and locked by au operator, when, and only when, he is ready to reload. When the door is allowed to remain open, it hangs IOO vertically and retains the tripping-lever of the empty car in a vertical position, thereby enabling the empty car to pass all the trippers without coming in contact with them.

The propelling-cable 12 runs between the members of a pair of horizontaljaws 15,which are fixed to a vertical standard 16, secured to one end of the car-body 17 and open and outwardly curved at their ends farther from the standard 16 to admit of the ingress and egress of the propelling-cable for the attachment and detachment of the car to and from the same. The propelling-balls 14 abut against the jaws at the narrow portion thereof adjacent to the standard.x Vhen detached from t-he cable, the car may be pulled or pushed along a track by manual or other power applied to one or another of two horizontal rods or bars 67.

Where a caris intended for use in transporting loads ot' different materials-as, for example, ore and rock-at different times, it is preferably provided with a signaling device for indicating to a switchman or other operator the character of the load in order that the car may be transferred to a side track leading to the point of discharge desired for one kind of material or be kept on the main track for the delivery of another.' To this end a double-armed signal-lever 68, provided with a central operating arm or handle 69, may be pivoted uponfone end of the car-body. The signals or semaphores 70 7l, which may be either of different colors or of dierent forms or be appropriately marked, respectively, to indicate the character of the load, are xed upon the ends of the signal-lever 68, either of said signals being concealed, according to the adjustment of the lever which is made by the operator who loads the car, bya screen-plate 72, fixed to the end of the carbody, between which and the car-bodyeither arm of the signal-lever may be swung and permitted to remain until replaced by the other, as may be required to indicate the' for retaining the door in closed position, and an upwardly and outwardly projecting tripping-lever journaled on the door and coupled to the locking-bolt, in position to be swung in its bearings and release said bolt by contact with a resistance applied at a point above the track.

2. The combination of a railroad-car, a door hinged to the car-body and controlling a lateral opening therein, a locking-bolt for retaining the door in closed position, and a. trippinglever journaled on the door and coupled to the locking-bolt, and projecting above the door-hinge, whereby the free end of said le- Ver is moved from and toward the car-body, respectively, in and by the closure and the opening of thedoor.

3. The combination of a railroad-car, a door hinged to the car-body and controlling a lateral opening therein, a locking-bolt for retaining the door in closed position, an upwardly and ou twardlyprojecting tripping-lever journaled on the door and coupled to the lockingbolt, and a tripper located above the track on which the car traverses, in position to contact with the tripping-lever, and thereby swing the same in its bearings and release the connected locking-bolt of the car-door.

4. The combination of a railroad-car, a door hinged to the car-body and controlling a lateral opening therein, a locking-bolt for retaining the door in closed position, an upwardly and outwardly projecting tripping-lever journaled on the door and coupled to the lockingbolt, an adjustable tripper located adjacent to the track on which the car traverses, and movable into and out of position to contact with the tripping-lever and to thereby swing the same in its bearings and release the connected locking-bolt of the car-door.
