JOHN J. TRAINOR, or NEW YORK, N. Y.

HOISTING AND DUMPING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 552,017, dated December 24, 1895. Application filed November 30,1894. Serial No. 530,313. (No model.)

To all whom it may concern:

Be it known that I JOHN J. TRAINOR, of the city and county of New York, in the State of New York, have invented a new and useful Improvement in Oableways, of which the following is a specification.

My invention relates to an improvement in cableways, in which provision is made for dumping the tub at any desired point throughout the limit of its travel by manipulating the hoisting-rope.

A practical embodiment of my invention is represented in the accompanying drawings, in which Figure 1 represents a cableway in side elevation showing the position of the parts when the tub is being elevated toward the carriage for the purpose of being conveyed away. Fig. 2 is'a similar view showing the position of the parts when the tub is being dumped, and Fig. 3 is a view in detail showing a different arrangement of the hoisting-rope.

The cable on which the load is carried from point to point is denoted by A and is commonly supported by struts B B located on some suitable firm foundation at or beyond the extreme points between which the load is to be carried, and has its ends anchoredas, for example, at a a. The carriage, which is mounted to travel along the cable, consists of a frame 0 having journaled therein a pair of supporting-wheels c c and carrying a pair of loose pulleys c c for guiding the hoistingrope. The struts B B also have mounted at or near their upper ends guide-pulleys 1) H19 12 for guiding the carriageoperating rope to and from the hoisting-engine.

The hoisting-engine is represented conventionally at D and is provided with carriage operating and hoisting drums d d. For purposes which will hereinafter appear the drums (1 cl are made of the same size. The carriageactuating rope (denoted by E) leads from the drum d, one part extending over the guidepulley b to one end of the carriage O and the other part extending over the guide-pulley b, thence to the guide-pulley b at the opposite strut B, thence around the guide-pulley b and back to the opposite end of the carriage O.

The hoisting-rope E extends from the drum d over a guide-pulley b at the strut B, thence to the guide-pulley c on the carriage, thence around the pulley f mounted in a block F from which the tub G is hung, thence up to the guide-pulley c on the carriage, around it and down to a guide f in the block F and thence to one edge of the tub G, to which it is secured; or the hoisting-rope may extend directly from the guide-pulley c on the carriage to the edge of the tub, as shown in Fig. 3. The point to which the hoisting-rope is secured is denoted by g.

The tub is so balanced that it will retain its horizontal position so long as the movable block F is free to be elevated, but when it is interrupted by contact with the carriage O the strain upon the hoisting-rope will be exerted upon the edge of the tub at g and the tub itself will be tilted and its load dumped, as shown in Fig. 2.

The operation is as follows: When the tub is loaded, the engine is made to operate the hoisting-drum (1 until the load has been elevated to a point near the carriage or to apoint sufficiently high for its transportation. The drums d and d are then simultaneously operated, the drum 6:! being operated in the one direction or the other to convey the loadv in one direction or the other along the cable, as may be desired. At the same time the drum d is operated the drum cl will be operated in the opposite direction, and the two drums being of the same size the hoisting-drum will take in or pay out the hoisting-rope just as fast as the carriage travels along the cable, so that the load will be retained at the same height. When the load reaches a point where it is desired to discharge it the drum cl is stopped and the hoisting-drum cl continued in motion and the movable block F brought into engagement with the carriage. As soon as it can no longer travel upwardly, the strain upon the hoisting rope takes effect upon the edge of the tub and the latter is tilted to discharge its load. When this is done the hoisting-drum is reversed to slacken the hoisting-rope and permit the tub to come back to its horizontal position, and having been returned to the point where it is to receive its load it may be lowered.

here it is desired to exchange an empty tub for a loaded one, it requires simply that the end of the hoisting-rope shall be attached to the edge of the loaded tub at the time of attaching the tub to the movable block F, and

this may be done by a removable fastening'of any Well-known or approved form.

lVhat I claim is- 1. A tub suspended in position to be tilted, a hoisting rope for elevating the tub and means for actuating the hoisting rope, the said hoisting rope being attaoheddireotly to the tub'at one side of its center of gravity whereby the hoisting strain may be imparted to the side of the tub to tilt it at a predetermined point of elevation, substantially as set forth.

2. The combination with a cable suitably supported a carriage mounted to travel-along
