AERIAL TRAMWAY.

Application filed January 18,1826. Serial No. 82,050.

My invention relates to tramways and more particularly to tramways in which the car returns to the loading terminal inverted. Such tramways include a haul rope for the car or carriage which haul rope is secured to the bottom of the car, the securing means being generally termed by engineers the haul link.

The present invention is embodied in what is usually termed the angle station, that is to say, where the track cables are turned through a horizontal angle between the loading terminal and the discharge terminal'.

The general object of the present inven: tion is to provide track means at the angle station referred to for the car on the return run and to provide an assemblage on said angle station whereby the haul rope is constrained to follow a path corresponding with the path of travel of the haullink se-' curing the haul rope to the car.

A further object of the invention is to provide an assemblage which will lnsure that the haul rope settles back on the end sheaves of the supporting structure at the angle station after the passing of a car through said angle station.

The, nature of the invention and its distinguishing features and advantages will more clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part of this specification, it being understood that the drawof the invention. I,

in the illustrated example of my inven-; tion, a structure known as an anglestation, that is to say, one in which the cables'are turnedthrough a horizontal angle between the loading and discharge terminals, is illuse trated, and includes posts A and transverse bars Ill-variously disposed throughout the structure, i a

A tramway includes upper and lowercoutgoing tracks D and return track rails E,jas well as upper guard rails F above the trackrailsD and E, the'car Con theoutgoing run being in normal position right-Side up whereas on the returnrun of the loop-line tramway at the different stations, including the angle whichhas been referred to above,

the car 0 travels on the return run on the tracks E at the angle station up-ended or inverted after dumping at the discharge stationi At the entrance end of the angle station guide sheaves 1-0 are providedffor thehaul rope :11. The numeral 12 indicates sheaves at that end of the angle station from which the track cables at depart.

The return tracks E and certain sheaves hereinafter referred to, in addition to the sheaves 10 and 12, embody my present invention as willappear. c

Attempts heretofore to control the inverted car 0 on the return run have included means to guidethe cable from the under side of'the inverted Scar c. provides means whereby the haul rope is constrained to follow a path corresponding approximately with the path of travel of the haul link which secures thecable to the car and whereby a secondary efiect is pro-l duced that the arrangement insures that the haul rope settles ba k on the end shear es The present invention 7 (10 and 12) of the supporting structure at the angle station after the passing of a car through said angle station.

The assemblage illustrated for carrying out the purpose of the invention in insuring the desired improved relation between the haul rope 11 and the inverted car includes in addition to the end sheaves and 12 at the angle station, a series of intermediate sheaves 13 on the frame structure of the station. These sheaves 13 are shown as four in number and they angle slightly to a horizontal plane transecting the upper guard rail F of the return tracks through the angle station. I employ a sheave 14 adjacent the first sheave 13 and a final sheave 14 adjacent the last angular sheave 13 passed by the car 0. Thus, the arrangement is such that the haul rope 11 upon entering the angle station runs over the top of the first sheave 10 at the entrance of the station. Then from the sheave 10 the haul rope 11 passes beneath the under side 7 of the vertical or approximately vertical sheave 14 and then past the angularly disposed sheaves 13 and from the last sheave 13' said haul rope 11 passes beneath the second sheave 14 and from said second sheave 14 the haul rope passes directly over the top of the sheave 12 at that end of the angle station from which the haul rope 11 departs in its passage on its return run toward the loading station. It will be seen that the several sheaves 13 and the sheaves 14 at the approach of the haul rope to the sheaves 13 and the departure of said haul hope from said angular sheaves 13 are so disposed that the haul rope is constrained to move along a line corresponding approximately with the path traversed by the haul link which haul and similarly the settling back of the haul rope on the pulley 12 is assured after the car 0 leaves the angle station and passes be-' yond said pulley 12.

The arrangement of the pulleys and the relation of the several pulleys 10, 12, 13 and 14 to the haul link 15 are such that the haul rope has no tendency to turn over the inverted car 0. i l

The track cables 01 terminate at the station, the terminals being anchored as at 16 (see Figure 1) below the return track rails E. Similarly, the track cables d associated with the outgoing track rails D are anchored at the station as at 17. Thus, the track rails Dand E bridge gaps or interruptions at the station in the running of the car on the track cables d. The numeral 18 indicates guide sheaves for the haul rope 11 associated with Besides the four sheaves 13 shown,

Reverting to the path of travel of the haul rope 11 corresponding with the path of movement of the haul link 15, said path of the haul rope is insured by forming a di or drop in the return track rails E at the station, said tracks, except at the ends thereof, being depressed.

I would state furthermore that while the illustrated example constitutes a practical embodiment of my invention, 1 do not limit myself strictly to the exact details herein.
