To all whom z't may concern:

Be it known that I, EDWARD OToonn, a citizen of the United States, and resident of Gary, inthe county of McDowell and State of West Virginia, have invented certain new and useful Improvements in Car- Dumping Apparatus, of which the following is a specication. 4

This invention relates to car dumping lo apparatus, and more particularly to car dumping apparatus for dumping mine cars, and has for its object the provision of such an apparatus that will be devoid of movable parts, and yet one that will invert the car and right it again while continuously moving along a track.

Another object is to provide a car dumping apparatus that will dump a greater number of cars than the dumping apparatus heretofore devised.

A further object is to provide a car dumping apparatus having the novel construction, design and combination of parts hereinafter described and illustrated in the accompanying drawings. v

In the drawings, Figure 1 is a somewhat diagrammatic plan of my invention.

Figure 2 is a diagrammatic side elevation.

Figure 3 is a partial plan of the dumping track, and Figure 3 is a continuation.

thereof.

Figure 4 is a partial side elevation of the entrance end of the dumping track.

Figures 5, 6, 7 and 8 are transverse sectional elevations on the lines V-V, VI-VI, -VIl-VIL and VIH- VIII of Figure 3, showing' the different positions of the car when traveling along the dumping track. A

Figure 9 is a transverse sectional eleva tion through the dumping track showing a slightly modified arrangement.

Referring more particularly to the drawings, the letter A designates the supply track leading to the dumping track B. C designates the locomotive return track and D the empt c`ar return track.

The supp y track A is of the usual track construction and consists of ties 2 and rails 3. The locomotive returny track C parallels the supply track and also -is of the usual track construction consisting of tiesfl supporting the rails 5. The locomotive return track C is connected to the supply The car dumping track B forms a continuation of the supply track A and is inclined downwardly from the supply track sopas to cause the cars to travel along the same by gravity.

The track B comprises upper and lower rails 8 vand 9 mounted on yokes 10 secured to beams 11, which bridge over a receivinf bin 12l below thetrack. The rails 8 an 9 are disposed tread to tread, and spaced equidistant throughout their length to enable the wheels 14 of the cars 15 to pass between them without binding. The track B is twisted to form a helical curve of 135 degrees in one direction to a point adjacent its transverse center line, then continues straight for a short length, and then is reverselytwisted in the opposite direction, forming a reverse helicalcurve of 135., degrees. It will thus be seen that cars passing along the track B will iirst be inverted and then righted while in continuous motion.

The track D or empty car return track B and is inclined `downwardly to the point 16, at which point a cable hoist 17 is located toraise the empty cars u to normallevel where they may be moved y the locomotive to anypoint desired for reloading.

The rails 8 and 9 are provided with side llanges 18 and 19, respectively, to limitthe side movement of the cars during the dumping operation.

The operation of the apparatus above described will be readily understood. The cars are moved by any welll known form of locomotive, cable or the like, along the supply track A. They then move by gravity along the dumping track B where they are inverted and righted as heretofore described, and continue by gravity along the empty return track D to the point 16 where they are engaged by the cable hoist 17 and elevated to the normal level portion of the return track.

If a locomotive is used'to push the oars yforms a continuation of the dumping track l along the track A it will be switched at the switch 6 to the ,locomotive return \track C. v

In Figure 9 an arrangement is shown for dumping cars having low \bodies, that is bodies lying close toy the wheels. In this construction the carbody 15 pro'ects over the wheels 14 and is so close to t e wheels that it is not possible for the upper rails 8 to engage the' upper portion o the wheel tread. Therefore a bracket 22 is secured to each side of the car vbody 15,\wh1ch brackets arevprovided with outwardly exf` tending arms on which are journaled rollers 23, Aand the` rails 8 are `spaced a greater distanceI apart than the rails' 9, lso as to overlie the rollers 23 on vthe brackets 22 instead lof the wheels 14. V

In' operation the apparatus` of F igurewill function the samel as' thatb heretofore p described, with the exception that the rollers 23 will engage the rails 8 when the car y is being dumped, instead of the wheels 14;

lWhile I' have shown and described only one specific embodiment of' my invention 'y it will beunderstood that various modifications may be made without departing froml 'a two-rail dumping trackupon which all the wheels of the cars to be dumped are adapted to travel, ,a series of retaining rails spaced above and .alined with the rails of said. Vdumping track, said dumping track comf prising a portion having both` rails twisted righting portion.

.up the carsas they uniformly in one direction from a horizontal position through asuiiicient angle to dumpv cars passingalong said track, and

'another`portion twisted uniformly in a reverse vrdirection ata point .beyond said `first mentioned twisted`portion to form a car 2. `A car dumping mechanism comprising asingle-track portion, means for slowing track, an inclined car umping track adapted to have thev cars move thereover by gravity, said dumping track comprising apair of traction and .supporting rails and a pair of guard rails spaced above and in alinement with'said traction rails, said traction and said guard rails being' arranged tread to tread, and said dumping track having a portion of its length twisted helically in one Ydirection f and a second portion twisted lieli cally in the reverse direction so as to autoass over said single matically dump and right the cars passing thereover.`

3. A car dumping mechanism comprising a single supply track portion, means for slowing up the cars as they'pass over said singletrack, an inclined car dumping track adapted to have' the cars move thereover by ravity,y said dumping track comprising a double track composed of a pair of traction and a pair of guard rails above said traction rails, said trac-tion rails and said guard rails being disposed tread to tread and havino' a portion of their length twisted helica ly in one direction and a second portion twisted helically in the reverse direction so. as to automatically dump and right the cars passing thereover, a return track leading 'from said dumping rack havlng an upwardly inclined portion in its length, and

means for conve ing the cars along said upwardly incline track.

n 4. The combination Awith a section of helically'twistedtrack adapted to invert and right cars passing thereover, of a supply track communicating with the entrance end portion yof said returnA thereoffavlocomotive return track paralleling said supply track and connected therewith by a switch, and an empty'car'return j track communicating with the discharge end of said dumping track.

5. The combination with a section ofl helically twisted track adapted to invert and right cars passing thereover, of a supplytrack communicating with the entrance end ythereof, a locomotive return track parallellbeing inclined-downwardly for a portion ofl its length and provided with a car elevating apparatus at the endof said inclined 6. The combination' with a section of inclined track twisted helically inopposite directions on the opposite sides of its transverse 'center line, of a supplyl track communicatng with thek entrance end thereof, a locomotive return track paralleling said supply track and connected therewithrby a switch, vand an empty car return track communicating with the discharge end of said dumping track, said empty car track being inclined downwardly for av portion` of its length and provided with a car elevating apparatus at the end of said inclined`portion.

In testimony whereof I have hereunto set my hand.

y EDWARD OTOOLE.
