APPARATUS FOR RAISING AN'D DUMPING COAL.

Specification of Letters Patent No. 15,300, dated July 8, 1856.

To all whom it may concern:

Be it known that I, EPHRAIM MORRIS, of Bergen, in the county of Hudson and State of New Jersey, have invented, made, and applied to use certain new and useful Improvements in Machinery for Elevating and Dumping Coal and other Materials; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing, making part of this specification, wherein.

Figure l, is a side view of an elevated railroad with my improvements as in use for transporting coal from a canal boat or barge. Fig. 2, is a cross section at the upper end of one of the frames or bents supporting the elevated railway, Fig. 3, is a plan, Fig. 4., a side elevation and Fig. 5, a cross section through the line A, A, of Fig. 4 showing in larger size the car which I use on the said elevated railway and the bucket into which the coal or other material is to be placed.

Similar marks of reference designate corresponding parts.

Coal from mines is very often brought to the yards or depots in canal boats or barges, and from these the coal has to be elevated and carried along to the desired place and dumped; and where the area for such depots is limited, the coal has often to be piled twenty or thirty feet high; this is very often accomplished at considerable cost by hand, the same being shoveled up from successive stagings; swinging booms and derricks have also been used for this purpose; and in some instances cars containing the coal have been run along on elevated railways and the coal dumped from them.

The nature of my invention consists in so constructing and suspending a bucket from a car on an elevated railway, that said bucket can be drawn along or run by its own weight to one end of an elevated railway and there be lowered down to receive its load, and then drawn up to the desired height and run along by means of the elevated railway, and dumped by one continuous pull on the rope that draws the same along, and then the car can be allowed to run back to its former position ready to receive another load; I am thus enabled to dump the coal at any desired place and at successive heights, and the same means can be adapted to use in filling up wharves with earth, or the excavations from the rivers or slips, and for other similar purposes.

In the drawing B, is the dock or surface of the coal yard or depot. C, is the sleeper and D, D, the inclined pieces forming each of the bents which support the elevated railway F, F, and E, is the top timber connecting the bents D, to gether, and these bents (D) can be of any desired height, and placed as close together as may be necessary, and said elevated railway might be level or nearly so and the car drawn along, although I prefer that the same should be inclined as shown, so thatthe car will run back of its own weight.

G represents the boat or other receptacle from which coal or any other material is to be removed and H is the bucket into,

which said material is to be placed, and this bucket is divided at the center so as to be opened at this point in discharging its contents, similar to that shown in my patent of December 12th 1848 for a scoop and elevator.

I is the frame of the car supported on wheels at, a, traveling on the rails F F, and on this frame are cross shafts carrying deeply grooved pulleys b and 0, which are geared so as to move together by wheels at, cl, so that the rope e, passing around in the grooves of the pulleys b, 0, cannot slip on said pulleys. The direction in which the rope e, passes around these pulleys is shown in Figs. 1 and 4, and from the pulley 0', the rope passes over a pulley or sheave f, at the upper end of the elevated railroad, to any competent motive power, which should be so arranged as to hoist stop or lower on said rope. The said rope in passing from the pulley b, descends through a hoisting block 9, attached to the bail w, of the bucket H, and the end of said rope is attached to the car I, at 1. Adjoining the wheel 0, is a ratchet wheel 71., taking the pawl 11, that is set on the cross shaft, 3, and the lower end of said pawl hangs down near the rail F. If the car be descending the rails F, the bucket H will be held in its elevated position because the wheels 05, and pulleys band 0, cannot run back and'let the bucket descend, (and draw the car up the inclined plane) because said pawl holds said wheels and pulleys, but when the car arrives at the lower end of the incline a stop piece 2 on the rail F, takes said pawl z, and disengages the same from the wheel h, and allows said bucket to run down to receive another load, and to prevent the car starting forward when the rope e, is pulled to hoist the bucket any suitable latch may be made use of which is disengaged when the bucket arrives at the required height, or the end of the inclines F F, may be at such a steep angle that the car will not be pulled up the same onto the less incline, until the bucket H is drawn up as far as it can come, and the whole power is then exerted to draw the car along.

The parts which I make use of for dumping the contents of the bucket H, by lifting up the outer edges of said bucket and opening the same at the center, as seen by dotted lines in Fig. 1 and thereby discharging the contents of said bucket when the same arrives at the desired point, are as follows.

7a, 7a, are rods attached by eyes to the cross shaft 3, and connected together at their lower ends, and as these rods determine the height to which the bucket is raised, they can be varied in their length or be attached to different pieces of timber depending from said shaft so as to dump the coal at successive elevations according to the length of the piece of timber made use of. These rods 7s 7s, carry by the eyes 4:, 4, the pin on which two bails m, m, are jointed, as seen in Figs. 4 and 5, and said bails are suspended at their outer end by chains 6, 6, attached at their upper ends to the car or to the rods Z0, 76, and

said bails are formed each in two parts so as to allow the rope e, to pass through the same and the ends of said bails m, are formed as hooks 5, adapted to take the loops Z, on the sides of the bucket H. It will now be apparent that when the bucket H is drawn up by the rope e, the hoisting block 9 will stop against the lower ends of the rods 72, and remain in that position until the car is lowered as before described. Therefore if the center (4:) of the joint of the bails m, be drawn up at the proper time, the hooks 5, will hang against and seize the loops Z, and open the bucket into the position shown by dotted lines in Fig. 1, and dump the load from the bucket H; this is accomplished as follows.-An eye 13, from the joint of thebail is connected to a rope or chain n, of the proper length to pass up and fasten to a grooved pulley or, on a shaft 7 set in journals on the car (1,) and on the projecting end of this shaft 7, is a drum 0, receiving chains 8, passing around said drum with one end connected thereto, the other to the rods from the eye or traveler 10, and g, g, are guides or supports for said rods and traveler: Through this traveler a rope g, is passed, and said rope g, has a knot 11, or similar projection formed thereon and is to be passed around the sheaves 12, and 13, near the ends of the top piece E, and the sheave 13, is provided with a handle by which the position of the knot 11, can be adjusted, and a clamp r, of any suitable construction secures the rope 9, when so adjusted. The operation of this part is, that when the car is being drawn along the incline or railway the eye or traveler 10, runs over the rope g, freely, and said rope rests on the pulley or drum [0, between the chains 8, 8,until the knot 11, comes in contact with said eye or traveler 10, and holds the same stationary, while the further motion of the car causes said chains to draw off from, and rotate the drum p, and grooved pulley 0, winding the chain 'n, 'thereonto and raising the bails m, m, and dumping the contents of the bucket H. The rope e, is then to be lowered on, and the car running down the incline, allows the bails m, m, again to descend and wind the chains 8, 8, onto the drum p, and also allows the bucket H again to close, when the further descent of the joint (t) of the bails in connection with the chains 6, 6, causes the hooks 5 to disconnect from the loops Z, and allow the bucket to descend as before detailed when it reaches the end of the elevated railway.

In some cases the bucket H will be required to dump at one uniform place, as in loading cars, and in this case the rope 10 may be dispensed with, and a fixed hook be provided to take an eye on the end of the chain a, and draw the same up over the pulley 0, as the car finishes its extent of travel. The rope 9, may be fitted with any convenient means, such as a weight, for allowing a certain amount of motion to the same, to prevent breakage in cases where the car was not stopped and allowed to run back, so soon as the chains 8, were drawn off the drum p, and any other arrangement for adjusting the position of the knot 11, or its equivalent may be made use of.

WVhat I claim and desire to secure by Letters Patent is 1. The pulleys b, and c, geared together so as to prevent the rope slipping when combined with the ratchet wheel h, pawl i and stop 2, or its equivalent whereby the bucket is sustained in its elevated position while being drawn along in either direction and can only be lowered when the pawl Z, is disengaged from the ratchet wheel h, substantially as specified.

2. I also claim the bails m, m fitted with hooks to take the loops Z on the bucket H when the same is elevated, and dump the contents thereof by drawing up said bails substantially as specified.

3. I also claim the adjustable rope g, with In Witness whereof I have hereunto set its knot or projection 11, taking the traveler my signature this twenty eighth day of May 10, and through the chains 8, 8, and n, and 1856.
