Specification of Letters Patent.

To all whom it may concern:

Be it known that I, JOHN H. BAisDnN, Jr., a. citizen of the United States, residing at Chattaroy, in the county of Mingo and State of \Vest Virginizu have invented certain new and useful Improvements in Car-Dun'iping Mechanisms, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain new and useful improvements in automatically operated car dumping mechanism and has for its object to provide a comparatively simple mechanism. of the above character which is adapted to be actuated by the cars to automatically release and remove an empty car from the rails of the track section by the movement of a loaded car thereon.

Another object resides in the arrangement of the car supporting means between the rails of the track section, said means comprising transversely movable shoes adapted to be positioned against the front truck wheels of the car to support the same in position to be dumped, said shoes being cooperatively connected with pivotally mounted longitudinally disposed bars adapted to be engaged by the truck wheels of a loaded car to release the empty car after the same has been dumped.

W ith these and other objects in view, the invention consists of the novel construction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawing, in which- Figure 1 is a side elevation showing the pivotally mounted track section and an empty and loaded car positioned thereon; Fig. 2 is a top plan view of the track section showing the operating mechanism; Fig. 3 is a section taken on the line 33 of Fig. 2; Fig. 4. is a section taken on the line as of Fig. 2; Fig. 5 is a view similar to Fig. 4 showing the car holding shoes in open position; Fig. (3 is a section similar to Fig. 3 showing the position of the parts when the shoes are open; Fig. 7 is a detail perspective view of one of the movable shoes and the reciprocatory rack bar connected thereto. Fig. 8 is a section taken on the line 8-8 of 2; Fig. 9 is a detail perspective View of one of the releasing plates.

Referring more particularly to the drawings 5 indicates a track section which may be supported upon any suitable frame structure and is mounted at one side of its longitudinal center upon a transversely positioned axle 6. The track rails 7 form a continuation of an ordinary car track 8 when the section 5 is in its normal position as shown in Fig. 1. The forward end of the pivotally supported track section 5 extends outwardly over the car. Built against one side of the frame immediately beneath the track section is a framework B which is adapted to limit the downward movement of the forward end of the track section when the car is disposed in dumping position upon the rails. This inclination of the track sections is approximately n at which inclination the entire contents of the car will be emptied into the dumping pit or conveying cars upon which the coal or other material is being loaded. The device is well adapted for the latter purpose as it obviates the necessity of frequent handling of the coal, the same being conveyed directly from the mine upon the tilting track section and there dumped into the cars in a manner which will now be set forth in detail.

Extending transversely between the rails 7 there is a channel bar 9. This channel bar is formed upon its ends with the laterally eX- tending flange 10 by means of which the same is rigidly secured to the webs of the rails as by the bolts 11 clearly shown in Fig. 2 of the drawing. One end of a longitudinally extending rock shaft 12 is journaled in a bearing 13 centrally secured upon the upper edge of one of the parallel longitudinal flanges 10 of the channel bar 9. This rock shaft extends rearwardly between the rails of the track sections and is actuated by suitable releasing means to be hereinafter described. Upon the forward end of the shaft 12 a segmental gear 13 is secured. This gear engages with the teeth 15 formed upon the surface of a reciprocatory rack bar 14. This rack bar also has the teeth 16 formed upon its inner edge which mesh with the teeth of the pinion 17 pivot-ally arranged centrally upon the base of the channel bar 10. A second rack bar 18 which is likewise adapted to have reciprocatory movement. between the flanges of the channel bar is also provided with teeth 18 upon its inner edge for meshing engagement with the teeth of the pinion 17. The opposite ends of rack bars 14L and 18 are angularly extended inwardly from the opposed flanges of the channel bar as shown at 19 and have their extremities arranged in the bifurcated inner ends of the rods 20. The ends of the rack bars are loosely connected to the ends of the rods 20 by means of the bolts 21. The outer ends of the bolts 21 are disposed through a rectangular opening 22 formed in each of the rails 7 of the track section. ilpon the ends of the rods 20 the shoes 23 are secured the ends of said rods being threaded to re ceive the nuts 24 to secure the shoes thereon. The head and outer flange of each of the rails is cut away or recessed as shown at 25 to receive the shoe 23, said shoe being adapted to fit closely upon the rail when engaged with the truck wheels as shown in Fig. 1. The inner ends of each of the rack bars have one end of a retractile spring 42 connected thereto, the other end of each of said springs being secured in any suitable manner to the web of the rail. These springs are adapted to retain the shoes normally in engagement upon the track rails. The base of the channel bar 9 is extended beyond the rails to form a support 26 for the shoes when they are moved outwardly from the rails to release the car. A guide flange 27 is formed upon one edge of the supporting plate and has its inner edge laterally extended as shown at 28 and is secured upon the outer face of the rail web by means of one of the attaching bolts 11. It will be noted from reference to Fig. 4 that the outer ends of the rack bars 14: and 18 are inclined upwardly as well as inwardly. In order to extend the outer ends of the rods 20 through the rails it is therefore necessary to bend the same as shown at 20. Thus as the rack bars are reciprocated in opposite directions and the shoes 23 moved outwardly and downwardly upon the supporting plates 26, the rods 20 will move freely through the rectangular openings 22 in the rails without danger of binding against the edges thereof.

The rear ends of the rails 7 of the track section are connected and braced apart by the parallel bars 29. A bearing plate 30 is centrally secured to one of the bars of each of said braces to receive the rear end of the central longitudinally extending rock shaft 12. Spaced pairs of L-shaped bracket plates 31 are secured to each of the rails 7 and project outwardly therefrom. Between these plates the link bars 32 are pivotally disposed and have secured to their upper ends the releasing plates 33. These plates are longitudinally positioned in parallel relation to the track rails and as shown in Fig. 2 have their rear ends outwardly curved as at 33' for the engagement of the truck wheels thereagainst in the operation of the releasing mechanism. The major portions of the link bars 32 depend below the track rails upon one side of the movable track section and are adjust-ably connected to the bifurcated outer ends of the substantially Z-shaped link rods or bars 34. The upper inner ends of these bars extend between the transversely arranged brace bars 29 and have their extrem ities bifurcated to receive the ends of the connecting links 35. These links are pivotally mounted between the depending plates 36 secured to the brace bars 30 and have their lower ends connected to similar links 37. The lower ends of the bars 32 mounted upon the other of the track rails have connected thereto one end of the inwardly extending bars 38 the inner ends of which are pivotally connected to the links 37. The rock shaft 12 is adapted to be actuated through the medium of the connecting links 39, the upper ends of which are rigidly secured to said shaft and have their lower ends adjustably connected to the inner ends of the bars 38.

In the operation of the device, the loaded car 40 moves upon the tilting track section and the forward truck wheels il thereof are engaged by the upper curved surfaces 23 of the shoes 23. When in this position the greater portion of the weight of the car will be disposed forwardly of the supporting axle (3, and the entire track section and the car will be tilted to an angle of substantially 45 over the dump or transporting car into which the coal to be deposited. The ordinary coal car as used in the mines is of comparatively light construc tion, and after the coal has been released 'tl erefrom the weight of said car will be overbalanced by the distribution of the weight of the track rails, the rearwardly extending portion of the rails rcturning the car to its normal position. The car is now supported upon the rails of the movable section and prevented from forward movement by the shoes 23. This car is released and projected for 'ardly upon the stationary track by the next loaded car which enters the tilting or dumping track section. Upon the entrance of this second car on the dumping rails, the forward truck wheels will engage with the outwardly curved end portions of the releasing plates and move or spread the same apart, said plates being normally disposed with their lower edges above the inner edge of the rail heads. Thus when these plates are engaged with the trncl: wheels there will be considerable outward movement of the same, which movement through the link connections between the bars 32 and the depending bars 39 rigidly connected to the rock shaft 12, will reciprocate the rack bars 1st and 18 in opposite directions and move the holding shoes 23 outwardly or away from the rails 7. Thus the truck wheels of the forward car are released and at the name time the rear of said car is struck by the loaded ear with sufficient force to move the empty car the required distance to dispose the same upon the stationary track before the truck wheels of the loaded car have passed from between the releasing plates 33. When the empty car has thus been released the retractile spring 42 will return the holding shoes s3 to their normal position to engage with the truck wheels of the loaded car to hold the same while it is being dumped as previously described. Thus it will be seen that the cars may be automatically dumped, eliminating the necessity of the frequent rehandling of the coal in its removal from the mine to the transporting cars. No manual labor is required beyond the initial loading of the coal ears, the pcnse incident to the handling of the coal in the manner at present in vogue being entirely overcome.

From the foregoing it is believed that the operation and many advantages to be attained by the use of my improved dumping mechanism will be readily apparent without requiring a more extended description.

The device is comparatively simple, has no delicate parts involved in its construction and is very positive in its operation.

The cost of installing the mechanism is comparatively small and it is also highly effieient and very durable in operation.

\Vhile I have shown and described what I believe to be the preferred embodiment of my invention it will be understood that the same is susceptible of numerous minor modifications without materially departing from the essential features or sacrificing any of the advantages thereof.
