ALBERT J. VVHEELDON, OF SMALL, KENTUCKY, ASSIGNOR OF ONE-HALF TO VILLIAM D. WARREN, OF SAME PLACE.

ELEVATOR-CARRIER.

SPECIFICATION forming part of Letters Patent No.`647,893, dated April 17, 1900.

Application tiled March 30, 1899. Serial No. 711.077. (No model.)

To ctZZ whom t may concern.-

Beit known that I, ALBERT J. WHEELDON, a citizen of the United States, residing at Small, in the county of Pulaski and State of Kentucky, have invented a new land useful Improvementin Elevated Carriers, of which the following is a specification.

This invention is a new and useful contomatically to return the carriage to the place of loading.

Another object is to so construct the apparatus as to be as free from noise as possible.

With these various objects in view my invention consists in the peculiar construction of the various parts and in their novel combination and arrangement, all of which will be fully described hereinafter and pointed out in the claims.y

In the drawings forming part of this specication, Figure l is a side elevation of my Fig. 2 is a top plan View. Fig. 3 is a sectional view on the Vline 3 3 of Fig. 2, and Fig. 4 is a section on the linee 4 of Fig. 2.

In carrying out my invention I employ a wire A, which is strung upon poles in a suitable manner and extends Afrom the point of loading to the point of discharge. A carriage B, provided with wheels B', travels upon this track or wire, said carriage comprisingan essentially-rectangular frame, in which the wheels are mounted, said wheels being grooved, as shown at B2, and in practice I prefer to face said groove with rubber or other suitable material for the purpose of deadening the noise as the carriage moves along the track orwire. A rope or cable C is attached to one end of the frame for the purpose of drawing it and the load it carries up to the discharge or dumping point. A pendent hook D is pivoted to the under side of the carriage B by means of a bolt D', the upper portion of said hook being bifurcated, as shown at D2, to providea suitable bearing and at the same time throw the hook proper directly in line with the grooved wheels and the track upon which they travel. The bearing-bracket D3, into which the boltD is journaled, is bolted to the under side of the carriage-frame and extends beyond one side thereof, as most clearly shown in Figs. 2 and 3. The wheels are journaled in boxes B3, which are made in sections, so that the wheels can be quickly and easily removed from the carriage wheneverdesired. The-axle of one of the wheels has a pinion E mounted thereon, whichpinion is engaged by a gear F, forming a part of a train of gearing contained within the frame B, mounted upon vone side of the carriage-frame, said train of gearing being moved by means of a gear H, having a spring I connected with its axle and to a stud upon the frame G, and this gear also has the usual construction of pawl-and-ratchet mechanism connected therewith, so that the spring will be rewound 'While the carriage is being pulled A locking-pawl K is pivotally attached to the frame and is adapted for engagement with the gear I-I whenever it is desired Vto prevent the operation of the train of gearing, and thereby liold the carriage in'a stationary position. The main spring can also be wound at any time through the medium of the winding-post L The frame G, with the gearing therein, is ar ranged upon the side of the carriage opposite to that from which the supporting-hook depends, and in this manner the entire device is balanced, and when a bucket of water or other material is suspended upon the hook I) the entire weight will be thrown directly upon the track or wire A.

In operation the spring is wound while the carriage, with its load, is being drawn by the cable, so that by the unwinding of the spring the gearing can be actuated so as to return the carriage for another load. VBy this means I gradually reduce the labor connected with the hauling ot' material by means of an elevated carrier and also insure the immediate or drawn with its load by means of the cable.

return of the carriage. Should it be desired to retain the carriage in a stationary position, the locking-pawl Kean be dropped into engagement with the pinion H, and in this manner they train of gearing is locked against Wheels` provided with rubber in the said gro.ov.esa bearing-bracket attached to said carriagefframe, a pendent support pivotally connected to said bracket, a spring-actuated trainofv gearing, arranged within the frameattaohedto the side of the carriage-frame, a

.locking-pawl adapted to enga-gc the power- Wheel of said. train of gearing, andthe pinion mounted upon the end of one of the WheelaXles, and with which the train of gearing is adapted to mesh for the purpose of moving the carriage in one direction, and a cable or rope attached to the. carriage-frame and adapted Y to move same in an opposite direction, substantially as shown anddescribed.

2. In a device of the character described, the combination with a carriage and a track upon which -it is adapted to travel, of a pendenthook D, the upper portion of which is bifurcated to provide suitable bearing-arms pivotally engaging the underside of the oarriage and securedV thereto byv a transverse bolt, the lower end of -said hook extending inwardly so that the-end thereof is in vertical 4alinementvviththe track, substantiallyl as described. f
