JOHN H. MILLER, OF MACDUNN, WEST VIRGINIA.

COAL-LOADING- APPARATUS.

Application filed November 16, 1920. Serial Ho. 424,399.

To all whom it may concern:

Be it known that I, JOHN H. MILLER, a

Citizen of the United States, residing at Mac- Dunn, in the county'of Fayette and State of West Virginia, have invented new and useful Improvements in Coal-Loading Apparatus, of which the following is a specification. This invention relates to means for loading railway cars, trucks, wagons and the like and is especially designed for loading coal cars at the mine.

An object of the invention is the p1'0-' vision of means whereby the transfer of coal from the mine dump to railway cars is facilitated, the said invention including a power operated shovel or scoop, which takes up coal and transfers it from the dump to the cars.

Another object is the provision of means for automatically throwing off the drag cable of the scoop from the guide pulley, both in the forward and return movement of the said scoop.

A further object is the provision of a novel form of scoop= which will 'dig into and gather its load and carry the same to the cars with a mimimum amount of power.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is a plan view of a'loading mech- I anism constructed in accordance with the invention.

Figure 2 is an enlarged detail plan view of the loading scoop.

Figure 3 is a side elevation of the same. Figure 4 is a central longitudinal sectional view. 1

Figure 5 is an enlarged side elevation of the throw-off pulley and a portion of the drag cable, the latter being in a position j 11st prior to the throw-off operation.

Figure 6 is a View similar to Figure '5 showing the cable about to leave the throwoif pulley.

Referring in detail to the drawings, wherelike characters of reference denote correspending parts, the reference character M,

indicates a portion of a main track which is located adjacent a mine coal dump lndicatedat D, the latter being located within an enclosure bounded by a wall or fence W. The dump enclosure is open as indicated at O and extending from this opening is an inclined chute S, which has suitably secured at one end an extention E, which is adapted to be moved into position to bridge the space between the'end of the chute S and the railway car R. All of the foregoing may be of the usual or any preferred arrangement.

Located upon the side of the track opposite the dump D and in a line with the chute S is a spur track indicated at 10. This track is designed to accommodate the operating mechanism which is mounted upon a wheel supported platform or car 11. This car may be operated upon the main track M and transferred to the spur track 10 by means of aturn table 13 of any approved construction.

Mounted upon the car 11 is an engine, preferably of the hoisting type as shown at Specification of Letters Patent. Patented Aim. 4, 1922 14. This engine is designed to operate a plurality of

drums

1,5, 16 and 17, the latter drag cable 24, which is (xmnected to a scoop 25 and which passes over a throw-off guide pulley 26. Also'connected to the scoop 25' is an inhaul drag cable 27, which. passes around guide pulleys 28 and is wound upon the drum 16. Thus, when the drums are rotated in one direction the cable 24 will operate to pull the scoop inward or toward the car 11 and when the drums are rotated in an opposite direction, the cable 27 will operate to pull the scoop outward or away from the car 11, the cable 24 being simultaneously paid out.

The scoop 25 which is shown in detail in Fi res 2, 3 and 4, comprises a bottom 29 anfl side walls 30, which converge at one end to provide a rear wall 31, to which one end of the cable 27 is secured. The opposite end of the scoop is provided with a flared mouth, while the forward edge of'the bottom 29 is curved downwardly as indicated at 32 so as to exert a digging action and force the coal or other material within the body of the scoop as the latter is dragged along. The forward edge of the bottom 29 has extensions upon either side as indicated at 33, the said extensions curving upward and forward as shown in Figure 4. a This prevents the edge 32 from digging too deeply into the coal and thus facilitates the movement of the scoop.

The cable 24 is connected to the scoop throu h the medium of a bail 34, whose ends are pivoted to the sides of the scoop as shown at 35. The forward ends of thesides are connected by an arch 36, which may be used as a handle if desired.

B reference to Figure 1 of the drawings it will be apparent that in order to move the .scoop from the position shown over the chute S to the car R, it will be necessary to disengage the cable 24 from the guide pulley 26 and one of the novel features of the invention resides in the r'ovision of means for automatically accomp ishing this operation. For this purpose the cable 24 carries an obstruction or button 37 and the pulley 26 has one of its flanges provided with a number of flattened portions 38, whereby the depth of the pulley groove will be reduced at these points. The groove of this pulley is designed to accommodate the cable 24 and as the diameter of the button 37 is greater, when this button reaches the pulley it will cause the cable to ride upward from the groove and as the depth of the latter has been reduced by cutting-away or flattening the pulley flange, the cable will be automaticall thrown ofl or disengaged from the pill ey so that the scoop 25 may move over the chute to the car B. After the scoop has dumped its loadit is drawn outward or away from the car by engaging'the cable 27 over the pulley 26, the cable 27 is also provided with a button 37 so as to be automatically thrown off the said pulley. As

soon as the scoop and the other button 37 passes the pulley 26, the cable is reengaged with the said pulley.

Wound upon the drum 17 is a cable 39,

'which passes over guidepulleys 40 and is in reserved to make such changes as properly fall within the'scope of the appended claims.

Having described the invention what is claimed is 1. In a loading mechanism, the combination with a source of power, a cable operated scoop, means for guidingl the scoop in a direction at right angles to t e line of pull, of a pulley provided with an interrupted flange and included in said guiding'means and means carried by the cable and co-operating with the pulley for automatically disengaging said cable from the pulley.

2. n a loading mechanism, the combination with a source of power, a cable operated scoop and means for uiding the scoo in a direction at right ang es to the line 0 pull, of a pulley included in said guiding means, said pulley being grooved and having its flange upon one side of vthe groove formed with a plurality of flattened portions to reduce the de th of said groove and means carried by t e cable to provide an enlarged portion, whereby the cable will be automatically thrown off the pulley when the enlarged portion reaches a reduced portion of the groove.

In testimony whereof I aflix my signature.

JOHN HQMILLER.
