APPARATUS FOR DUMPING COAL-CARS.

SPECIFICATION forming part of Letters Patent No. 339,838, dated April 13, 1886.

Application filed September 30, 1885. Serial No. 178,601.

To all whom it may concern.-

Be it known that we, STATEN ANDREW BARNES and W'ILLIAM LAWS, citizens of the United States, residing at Hopwood, in the county of Fayette and State of Pennsylvania, have invented certain new and useful Improvements in Apparatus for Dumping Coal-0ars; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to mechanism for dumping cool-cars, such as are used in mines, wherein the cars are run bodily upon a section of the track,which tilts sidewise, said section being provided with means for retaining the car in place, whereby the entire contents of the car may be dumped at once into a suitable receptacle below the track. These sidewisetilting track-sections are not new for this purpose; but they have hitherto been located at the end of the track, and so constructed that in order to dump a car it has been necessary to uncouple the car from the train,and to run it first onto the tilting section and then back again out of the way before asecond car could be dumped.

Nith a tilting tracksection constructed and arranged according to our invention a car can be dumped without uncoupling it from the train, and accordingly the section may be conveniently located at any part of the track.

In addition our invention includes an automatic trip, which is used when the tilting section is at the end of the track,and other minor details, which will be hereinafter more specifically set forth.

In the drawings, Figure 1 is a side view of our improved dumping apparatus. Fig. 2 is an end View of the tilting section in its normal position. Fig. 3 is an end View of the section when tilted, and Fig. 4is aview of the end of a tilting section, showing an automatic trip.

Ais the tilting track-section,which is adapted to tilt sidewise. Along its bottom are placed rails a a, which form a continuation of the main track. When a car, B, is to be (No model.)

dumped,it is run upon this section,and is held thereon during the dumping process by means of horizontal guard-bars O G,which constitute part of the frame-work of the tilting section, and are located immediately above the rails a a, there being just space enough between the rails and guard-bars to admit the wheels D D of the cars. These cars are solidly built, their bodies being usually securely fixed to the axles, so that when the section is tilted they are pre Vented from falling out of the section by means of the treads of the wheels engaging with the guard-bars.

The coal-cars are usually connected together by a chain-coupling, as shown at b, so that there is usually some space between adjacent cars, and the tilting section is so mounted that the cars can be dumped without uncoupling from the train. To permit this to be done,the trunnions E E, on which the section turns,are fixed to vertical posts F F, secured to the bottom of the section, and turn in bearings G G, which are formed in raised blocks on the main tracks at either end of the tilting section. These trunnions are fixed as high above the rails cm as the space beneath the axles of the cars will permit,and the axis on which the section turns is thus high enough to permit the cars to be entirely reversed without interfering with the coupling. The section is preferably mounted a little to one side of the center, so that when a loaded car is run thereon its weight will antomatically turn the section. To prevent this being done at improper times, the section is held from turning by a spring-catch, d, which engages a lip, e, fixed to the tilting section. This catch is released by a hand lever, f. When the catch is thus withdrawn,the section tilts and the coal is dumped, and the section is returned to its normal position by a counter-balance, H, fixed to the section.

In case the tilting section is located at the end of the track, an automatic trip is preferably employed. This trip is composed of a spring-catch, d, which engages an aperturein a beam, 0, arranged on one end of the tilting section. Abuffenbar, 1, slides in the catchaperture in beam 6, and in an aperture in a bar, 6 and is normally held out of contact with the catch (1 by a coiled spring, g. When a car is run onto the section,one of its wheels engages the buffer-bar I, pushes it against the ICO catch, thus releasing the catch and permitting the section to turn. 1

In order that the turning of the section may be regulated; a brake mechanism is used in connection therewith. This consists of a brakewheel, J to a crank-pin, h,on which one end of a connecting-rod, K, is attached. The other end of this red is pivoted to the tilting section. A brake-strap, L, secured at one end to a fixed support, passes around the periphery of the brake-wheel, andis secured at its other end to one end of a pivoted brake-lever, M.

We claim as our invention- 1. A tilting track-section provided with rails which constitute a continuation of the rails of the main track, the axis on which said section turns being located above the plane of the rails, substantially as and for the purpose'setforth. 2. A sidewise tilting track section upon which cars are run to be dumped, said section being provided with a counter-balance which restores it to its normal position after the car has been dumped, substantially asset forth.

tion,which co-operates to release said track when the car is run upon said section, substantially as set forth.

4. A tilting track-section, in combination with a brake-wheel, a connecting-rod connecting said section with a crank-pin on said brake-wheel, an operating brake-lever, and a brake-strap which is secured atone end to a fixed support passing around the periphery of said wheel, and is attached at the other end to said brake-lever, substantially as set forth.

I In testimony whereof we aflix our signaturesv in presence of two witnesses.
