COAL-UN LOADING- DEVICE.

Specication of Letters Patent.

Patented Tune 26, 1911*?.

To all whom t may concern:

Be it lmown that I, JAMES H. TU'rwILnR, a citizen of the United States, and a resident of Atlanta -in the county of Fulton and State of eorgia, have invented an Improvement in Coal-Unloading Devices, of which the following is a 'speciication y invention is an improvement 1n coal unloading devices, and has for its object to provide mechanism of the character specifled, comprising end frames adapted to be connected with a coal car and adjustable to various sizes of cars, the said frames carrying a rail, upon whicha carriage 1s mounted to travel from end to end of the rail and the frame, the said carriagel carrying a bucket for receiving the coal, and a scale for Weighing the bucket and the coal, the bucket being connected to the scale by hoistlng mechanism to permit the bucket to be raised or lowered.

1n the drawings:

Figure 1 is a front view of the improved unloader. y

F ig. 2 is an end view, with parts 1n sec- FigB is a partial perspective view of the top of one of the end frames.

Fig. 4: is a similar view of one end of the rail.

YThe present embodiment of the invention is shown in connection with a coal car 1,' and the improvement comprises two substantially triangular frames adapted for connection with the side of a car, and a s ectional standard is provided in connection with each end frame, each standard having interlocking engagement with the adjacent frame.

Each end frame is right triangular in form, the three sides being of angular material, and the hypotenuse side 4 is braced against the angle by an inclined brace 5. 0n the long side 3 is a clamp or clip 6 consisting of portions offset laterally with respect to each other and integrally connected,

and one of the portions is adjustably connected to the side 3 bymeans of bolts 7 and handle nuts 8. The side 3 is provided with a series of openings, to permit the bolts to be connected with di'erent openings, so that the clamp may be connected with the side at diferent heights, to provide for varions makes of cars.

. rlhe other portion of the clip or clamp engages over the side of the car, as shown in 2, with that portion of the said sideA below the clamp engaging the outer side of the car and with the side 2 horizontal. At the right angle or near the right angle the side 3 is provided with an eye 9, for permitting the attachment of a guy, not shown, for guying the frames. These guys may be stretched across the car or connected With the opposite side of the car, or they may extend in inclined position longitudinally of the car side.

For supporting the outer side of each frame a standard is provided, each standard consisting of an outer section 10, an inner section l1 and a base 12. The section 11 is mounted to slide in the section 10, both sections being hollow pipes, and the sections are held in adjustedposition `with respect to each other by means of pins 13, which are passed through series of registering openings inthe standards. The base has engaged with the upper end thereof a screw 13, and this screw has a plain portion 141 at its upper end which engages within the lower end of the section 10. The screw is enlarged between the threaded portion and the plain portion, as indicated at 15, and ythis enlargement provides a shoulder against which the lower end of the outer section abuts. rllhe enlargement is also provided with radial openings 16, for permitting the insertion of a bar to turn the screw to raise or lower the section 10 with respect to the base. The upper end of the section 11 engages with a depending socket 17, on the outer end of a plate 18 which is secured to the side 2 at the outer angle of the frame in any suitable manner, as, for instance, by rivets, as shown. The plate is so arranged that the socket depends beyond the frame, and the upper end out the section 11 is engaged within the socket.

A rail in the form oi an 1-beam 19 rests upon the sides 2 which form supporting bars and guides for the rail. This rail is provided on its under side near each end with a pair of spaced clips 20, which are spaced apart far enough to engage opposite scale indicated generally at 23 is supported by the carriage. A pulley 24 is connected with the scale at the center of the lowerinost beam, and a second -pulley 25 is connected with a bucket 26 for receiving the coal.

This bucket has a bail 27 which engages the hook of the pulley 25, and the said pulleys 24: and 25 together with a rope Q8 constitute hoisting apparatus for fraising and lowering the bucket. It will be noticed that the bucket when loaded normally does not balance, one side being heavier than the other, and it is held from dumping by means of hooks 30 which'are pivoted to the bucket and engage the bail,-y to hold the bucket in loading position. A pair of wheels 3l is journaled on the bottom of the bucket, on an axle, which is held transversely of the bottom and below the same, for a purpose to be presently described.

In operation, the apparatus is assembled by engaging the clamps 6 over the side of the car. The standards are adjusted to the proper height and engaged with the sockets 17, after which the rail 19 is properly arranged. A spirit level 32 is arranged on the carriage, and by means of the jacks at the bottoms of the standards, the frames are adjusted until the rail 19 is level. The carriage is mounted on the rail, and by means of the hoisting or block and tackle mechanism the bucket is lowered or raised to the proper height for filling from the car. The coal is shoveled into the bucket, and the said bucket is designed to hold a ton of coal. By means of the scale the coal may be weighed, and by means of the carriage the bucket may be moved to the desired point for unloading. The unloading may commence at one end of the car and progress to the other, and by means of the hoisting o1 block and tackle mechanism the bucket may be lowered into the bed of a wagon and moved to the desired dumping point, the bucket rolling upon the wheels 31, and the axle forming a handle for manipulating the bucket.

I claim:

1. A device of the character specified, comprising substantially right trlangular end frames, each having at one acute angle a socket and having on the opposite side a clamp for engaging the side of a car and adjustable longitudinally of the said side, an adjustable standard engaging the socket at its upper end and adapted to rest upon the ground at its lower end, said standard comprising inner and outer sections adjustable longitudinally of each other and having means for holding them in adjusted position, and a jack base for raising and lowering the inner and outer sections, a rail for connecting the top sides of the frames, said rail having pairs of lugs at its ends for engaging the opposite sides of the end frames, a carriage movable on the rail, a scale supported by the carriage, and

'a bucket having a block and tackle connection with the scale.

2. An apparatus substantially as herein described, comprising uprights having means whereby they may be vertically adjusted and cross frames corresponding to said uprights and having at thelrv outer upper ends means for interlocking engagement with the upper ends of the uprights, said cross frames also having top bars constituting rails and upright bars having.

means for engagement with the side of a car and adapted for detachable engagement therewith, a beam traveling on the top bars or rails of said cross frames, a carriage traveling on the beam, and a bucket suspended from the carriage, all as and for the purpose set forth. JAMES H. TUTW'ILER.
