T. HOOLE. Improvement in rCoal Conveyer and Elevattyr.

Patented Sep.24,1872,'

mummy Josnrn r. Hoo s, or EBUFFALO, NEW YORK.

Specification forming part of Letters Patent No. 131,683, dated September 24, 1872.

To all whom it may concern:

Be it known that I, JOSEPH THOMAS Room, of Bufialo, in the county of Erie and State of New York, have invented an Improved Goal Oonveyer and Elevator, of which the following is a specification:

It is the object of my invention to afford facilities for moving coal on docks, in yards, and other situations, and to place it on board a of vessels or cars by mechanical power, thereby dispensingwith manual labor in shoveling i and wheeling; and it consists in the arrangement of scoops or shovels in connection with ropes or chains and pulley-bearings, in com bination with an inclined plane or planes, screen, and chuteor pockets, whereby, with suitable power applied, one scoop or series of scoops advances and deposits its or their load or loads on the screen or in the pockets, while another scoop or series thereof simultaneously recedes to receive another load or loads, all as hereinafter fully described.

In the drawing, Figure l is a sectional side elevation, and Fig. 2 isa plan view.

As shown in the drawing, :0 represents a wharf, on which are erected two upright posts or standards, AA, or other suitable framework, onwhich is supported the elevated end of an inclined plane or floor, B, having vertical sides a, a and a central longitudinal partition, b, (best shown in Fig. 2.) Connected with the elevated end of this .incline is a reverse inclined chute or spout, O, which forms the upper part of the mainchute E. The bottom of the chute (J is composed of a movable wire-cloth screen or sifter, 0, over which the coal is separated from the dust and dirt,

T which falls through its meshes while the coal passes over into the chute E. On either side of this screen and above it are arranged two pulleys or blocks, dd, through which ropes orchains f f run, and to which are connected over two pulleys, hit, each pulleybeing attached to an upright post or strong frame-work, t i, as shown; the rope y then extends forward to, and isconnected with, the other bucket.

This arrangement of the ropes or chainsf and g g forms, as it were, an endless belt w1th the buckets attached. The standards 6 i can be set at any distance from each other and from the frame-work A A that may be required to comprehend the coal or ore to be worked on, by employing a length of chain or rope corresponding with such distance,

' It will readily be seen that if the rope f is pulled in adirection toward the chute the bucketto which it is attached will bedrawn along the surface of the pile J J, and will scoop up and fillwith the coal and draw it up the inclinled plane, where it will discharge either into a "coal-pocket or on the screen, as may be required, the coal so discharged being conveyed by the chute into'the vessel or other receptacle. The ropes or chains and buckets being geared in the manner described, it is obvious that the act of drawing one bucket forward simultaneously moves the other bucket back. The shape of the buckets is such that in moving backward they pass freely over the coal without filling. The rope and buckets are operated by a stationary engine or other power, placed in any suitable position, to which the ropes ff extend, as shown in Fig. 2, and the motion is reversed when the bucket of one side has discharged its contents on the screen 0 and the other advances withits load. Thus each bucket loads, discharges, and returns alternately in succession. The division b in the incline plane is for the purpose of keeping a clear way for each bucket as it advances and recedes. If it should be required to move the coal in the opposite direction it is easily accomplished by reversing the buckets D D. The action of the bucketsin moving backward or forward is shown by the line J J, which indicates the top of a coal-pile.

This device is'of great importance andntility to coal-shippers and others, as it dispenses with the labor of many men in shoveling and wheeling the coal on a level and hoisting it to drop it into pockets, chutes, &c. The incline B leads directly to the pocket or chute, and coal drawn up by this method falls at once into either, as desired, saving thereby greatly in labor, time, and expense of handling.

What'I claim as my invention, and an im-' provement in machinery for moving and ele va'tin g coal, is-

The scoops D D, and ropes or chains f f g 9, arranged in connection with the pulleybearings d d and h h, and suitable power to alternately advance and recede, in combination with the incline B and. screen 0 and pocket or chute E, substantially as and for the purpose set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
