SPECIFICATION forming part of Letters Patent No. 791,477, dated June 6, 1905.

Application filed October 18,1900. Renewed November 8, 1904. Serial No. 231,954.

To aZZ whom it may concern:

Be it known that I, WILLIAM A. LATHROP, of Wilkesbarre, in the county of-Luzerne, and in the State of Pennsylvania, have invented certain new and useful Improvements in Car- Dumps; and I .do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, in which I Figure 1 is a side elevation of my car-dump, and Fig. 2 is, a transverse sectional view thereof.

Letters of like name and kind refer .to like parts in each of the figures.

The object of my invention has been to provide a car-dump by which the contents of a loaded car can be readily transferred to a receptacle therefor or other place of discharge; and to such ends my invention consists in the car-dump hereinafter specified.

In carrying my invention into practice I provide a framework A, consisting of posts or uprights a; and a, upon which are supported upper cross-beams a and a, that carry upper stringers a and a and lower cross-beams a and a which carrylower stringers a and a Intermediate cross-beams a and a are also supported by the posts or uprights a and a, and such cross beams carry intermediate stringers a and a. The upper and intermediate stringers which support the rails extend from the rear side of the framework only part way across the same. Rails B and B extend along the upper stringers a and a and are then curved down and back and extend for a short distance along the intermediate stringers a and a. From the intermediate stringers the rails B and B are curved down and forward to meet the lower-stringers a and a, along which they pass to carry the car away from the dump. There is thus in efiect an upper and a lower track connected by an S-shape track. Guard-rails C and O extend parallel to the S-shapeportions of the rails B and B and at a distance therefrom equal to the diameter of the car-wheels, such guardrails being supported by braces c and 0, secured to the rails B and B.

A vertical apron D extends down the forward posts a and a from the upper stringers to its normal position.

to a'point where it meets an inclined apron E, and the latter extends downward and rearward until it meets a double chute F, which is bridged over the rails B and B and extends downward on each side thereof.

In the operation of my car-dump the car, propelled in any desired manner, is run along the upper straight portions of the rails B and B until it reaches the curved portions thereof, where are also the guard-rails G and O. The car then descends the curved portions of the rails B and B and the guard-rails, the car being gradually overturned by such action and its contents thrown against the aprons and into the chute until at the portions of such rails which are attached to the intermediate stringers the car is completely inverted and entirely emptied into the chute. The car then passes down the remaining curved portions of the rails, and thus becomes restored The chute being elevated above the rails B and Ballows the car to pass thereunder and along the portions of the rails B and B which extend along the lower stringers.

Changes which donot involve a departure from the scope of my invention may be made.

For instance, it is manifest that during the rearward portions of the travel of the care'. 6., from the forward portion of the upper bend to the rearward portion of the lower bend-the weight of the car is*on the guardrails. If desired, the rails B and B can be omitted along the portions where the weight of the car is on the guard-rails, and the guardrails can be omitted along the remaining curved portions of the rails B and B..

Having thus described my invention, what I claim is 1. The combination of two substantially horizontal tracks, in a higher and a lower plane, respectively, and a vertical compound, curve connecting said tracks, one portion of which is substantially horizontal, such portion being below the upper track and above the lower track, wherebya car in traversing said curve is inverted.

2. The combination with two substantially horizontal tracks,in a higher and a lower plane, respectively, connected by a vertical compound curve, one portion of which is substantially horizontal; such portion beingbelow the upper track and above the lowertrack, whereby a car in traversing said curve is inverted, of a car having a plurality of-wheels in a single plane, adapted to run on said tracks and curve..

3. The combination with two substantially horizontal tracks,in a higher and a lower plane, respectively, connected by a vertical cornpound curve, one portion of which is substantiallyv horizontal, of. aear. havingva plue rality of wheels in a single plane, adapted to run on said tracks andcurve, sueh'cur-ve-acting to invert said car, thus discharging its contents.

4a The-combinationwith'twosubstantially horizontal tracks, in a higher'anda lowerplane,

respectively, of a vertical compound. curve upperztrack and above' the lower track, whereby a car traversing said trackisinverted.

6. Thecorn'bination' of two substantially horizontaltracks,in a-higher and a lower plane, respectively, a verticalcompound"curve; con+ necting said tracks, consisting of an upperforward convex curve and a lower-rearward convex curve, and a car'adapted" torun" on: said tracks and curve, such curve acting to invert said car, thus discharging itscontents.

7. The combination of two substantially horizontal tracks,-in a higherand alower plane, respectively, a verticalcompound curve, connecting said tracks, consisting in an upper forward convex curve and a lower rearward convex curve, such curves being connected by a substantially. horizontal portion; and a car adapted to run on said tracks and curve, such curve acting to invert said car, thus discharging its contents.

8. The combination with a car, having a plurality of pairs of wheels-inasingle plane, of a track having a vertical compound curve upon whichsuchwheels are adapted to run,

" anda receptacle opposite the upper portion of such curve in positionto receive'thecontents-0t said car as-the car isemptied in traversing such curve,- substantially as and for: the pu rpose described.
