Letters Patent N 101,115, lated March 22, 1870.

IMPROVEMENT IN CAR, TRACK, AND OPERATING-APPARATUS I'OR MINES.

The Schedule referred to in these Letters Patent. and making part of the same.

To all whom it may concern:

Be it known that I, WILLIAM B. FRUE, of Houghton, in the'county of Houghton and State of Michigan, have invented a new and improved Car-operating Apparatus; and I do hereby declare that the following isa full, clear, and exact description thereof, whichv will enable others skilled in the art to make and use the saine, reference being had to the accompanying drawing forming part of this specification. This invention-relates to improvements in apparatus for operating cars upon short tracks from the receiving to the dumping-place, such as required in mines, shipping-places, and the like.

The invention consists in combining and arranging,

' in connection with a'short railroad track, cert-ain instrunientalities, which will be more` particularly described hereinafter, and specified in the claim.

Figure 1 represents a longitudinal sectional elevation of, my improved apparatus, taken on the line a: a: of fig. 2, and

Figure 2 represents a transverse section, taken on the line y y of fig. 1.

Similar letters of reference indicate corresponding parts.v

A reresents an elevated track, and B the cars thereon, to which a cord or chain, C, is attached, and passes over pulleys D, at each end of the track, to the grooved pulley E on the shaft F. The cord passes around this pulley and derives motion therefrom, winding on in one direction and off in the other, when the shaft turns one way, and rice rcrsa when the shaft turns the other-way.

On this shaft are' placed two fast pulleys G H, and

two loose pulleys I K, and below it is the drivingdrum L.

'Iwo belts, M N, are used, the one crossed and the other not, each belt having an independent belt-shifter,

0 P. The one belt drives the shaft F one way and the other the other way.l

When the crossed belt M is working on the fixed pulley G for driving it one way, the other belt, N, is working on the loose pulley I, and for driving the shaft F the other way, the two belts are respectively shifted. The shifting is effected simultaneously by turning the lever of one shift-er in one way and the level' of the other shifter in the other.

Stops a are placed upon each end of track to stopthe car and overcome the friction of pulley E upon the belt, (in case of carelessness of the operator,) when the -said pulley will slip within the belt until the latter is shifted to the loose pulley. The rope or belt is fastened to an eye on the axle d.

The running gear to which the car-body is attached -consists of four wheels, two commuting-bars, and two axles, d c. rIhe car is attached, at or near its middle,

to the. axle d, which faces toward the dumping-end of the track.

When at the right or loading-end, the car lies h ori zontall'y uponf the two axles, but when it is forced against the stop at the left end, the impact' will cause. it to vibrate with the axle in a vertical plane, and autornatically dump the load.

Having thus described 'myinveutiom What I desire to protect by Letters Patent is \'1he combination of a short track, A, having a stop, a( and vertical sheave D at each end, with a drivingpulley, E, and endless belt C, the two relatively arranged and co-operating, as set forth, to move the car B and dump the saine, at the time and in the manner described. i
