To all whom it may concern:

Be it known that we, WiLLiAM J. PATTER- SON and Ross M. BICKLEY, citizens of the containan unusually high percentage ofrefuse such as stone or slate, due to carelessness of the miner in loading said cars. It is necessary to call the miners attention to this refuse so as to discourage the practice of sending out dirty coal. Where cars are hoisted from the mine to the tipple on selfdumping cages the identity of any particuthe coal dumped from the car, and said chute lar car is lost as soon as it is dumped unless some provision is made for diverting the coal for inspection. I

In the cleaning of coal itis found that the greater part of the easily removable impurities are found in the size larger than one and one-quarter inch. By our invention provision is made therefore for screening the coal, for weighing the lump and slack coal together and delivering them together to a bin or other receptacle, or for delivering the slack only to the bin and delivering the lump coal to the picking table, where it may be inspected by the miner or inspector,

The refuse that is pickedput may then be weighed to determine what percentage the impurities were of the total weightiof coal in the car. After the refuse has been picked out the coal may be delivered to the bin by reversing the direction, of movement of the picking table, said table being arranged in such proximity to the bin as to effect this result. If, however, all of the coal is con-= sidered bad it may be discharged into a refuse chute from the picking table.

Specification of Letters Patent.

In the accompanying drawing Figure 1 1s a side elevation of our improved apparatus shown inconnection with an ordinary ing' the cages when they. reach the dumping pointand the .mechanism illustrated is a common form which forms no part of my present invention. Said mechanism comprises generally statedthe curved guide 6 adapted to receive the rollers '7 on the cage, whereby the cage carrying the car is dumped the position indicated by dotted lines A chute 8 is located in position to receive delivers the coal to the weigh-hopper 9. This weigh-hopper 9 is divided by the screen bars 10 into a to and bottom deck 11 and 12. Gates 13 an 14 are provided for the upper and lower decks 11 and 12 respectively, said gates being opened and closed by means of the fluid-operated cylinder '15. The piston-rod 16 is connected to the bellcrank 1'? 'and a rod 18 connects said bellcrank to the gate'13. Bars 19 and 20 are pivoted to the gate 13 and to the hopper 5,, and a bar 21 ispivotally connected to the bar 20 and to the gate 14. By these connectiohs the operation of the cylinder 15 acts to open and close the gates 13 and 14 simultaneously. 1

"tip-ple; Fig. 2 is a plan vview; Fig. 3'is an upper deck 11 of the weigh-hopper 9, and

said chute 25 is provided with the opening 26 in its bottom controlled by the fly-gate 27, hinged at 29. This gate 27 is opened and closed by the fluid-operated cylinder 30, piston rod 31 of said cylinder being connected up by the arm 32 to said gate whereby said gate may be moved into position to close the opening 26 or may be raised to the position indicated in dotted line Fig. 3, where it is desired to discharge the contents of the upper deck 11 into the chute 22.

The lower end of the chute 25 is also provided with a gate 33 hinged at 34 and raisedand lowered by a cable 35. In this manner provision is made for retaining the coal delivered to the chute 25 in said chute until it is desired to deliver it onto the pickingtable 24.

The picking-table 24 may be of any suitable construction, that shown being of a common type consisting of an-endless con veyer belt 24 mounted on drums 24. Any suitable means may be provided for driving the belt 25 and for reversing its direction of movement.

An operating platform 40' is provided for the operator from which he is able to control the cylinders 15 and 30 by means of the levers 41 and 42 respectively.

The operation of our invention is as follows:

The cars of coal are hoisted onthe cages in the shaft and on reaching the dumping point the cars are dumped and the contents delivered into the weigh-hopper 9. The finer coal or slack will fall through the screen bars 10 onto the lower deck, while the larger or lump coal may remain in the up-- per deck 11. The coal is then weighed. If the inspector from his position on the cage tenders platform sees that-the coal is free or compartively free from refuse, he signals the operator who by means of the lever 41 operates the cylinder 15 and through the connections described opens the gates 13 and l4,the gate 27 having been raised to the position indicated in dotted lines Fig. 3. This permits the coal from both decks to pass into the chute 22 and into the bin 23.

If, however, the inspector believes that the coal in the upper deck 11 contains too great a percentage of refuse he signals the operator who moves the lever 42 and opcrates the cylinder 30 which lowers the gate 27 to close the opening 26 in the chute 25. He then moves the lever 41 to operate the cylinder 15 and the gates 13 and 14 are opened. The slack coal in the lower deck 12 passes as before down into the bin but the lump coal is delivered into the chute 25 and is collected at the lower end thereof. The picking-table 24 is then put in operation and the coal is delivered by lifting the gate 33 to the picking-table, a sufficient are of the total weight of coal in the car.

The cleaned coal on the picking-table 24 may then be delivered into the bin 23 by reversing the travel of the belt 24".

What we claim is:

1. In apparatus for cleaning coal, th combination of a weigh-hopper, a screen dividing said hopper into an upper and lower deck, said upper and lower decks having discharge openings, gates controlling said openings, means for operating said gates, a common chute to receive the contents of said upper and lower decks, a picking-table and means for diverting the coal from the said upper deck to said picking-table.

2. In apparatus for cleaning coal, the

combination of a weigh-hopper, a screen outlets, means for operating said gates, a'

chute in line with said upper deck, a com mon chute to receive the coal from said upper and lower decks, said first named chute having an opening communicating with said common chute, a gate for said opening, and a picking-table to receive the coal from said first named chute.

3. In apparatus for cleaning coal, the combination of a weigh-hopper, a screen dividing said weigh-hopper into upper and lower decks, said decks having discharge openings, gates controlling said openings, a common chute to receive the coal from said decks, a traveling picking-table, and means for diverting the coal from said upper deck onto said picking-table.

4. In apparatus for cleaning coal, the combination of a weigh-hopper, a screen dividing said hopper into upperand lower decks, said decks having discharge outlets, gates controlling said outlets, a common chute to receive the coal from said decks, a bin, a traveling picking-table, and means for diverting the coal from said upper deck to said pick1ng-table, said picking-table being in proximity to said bin whereby the ljcjoal on said table may be delivered to said 5. In apparatus for cleaning coal, the combination of a weighhopper, a screen dividing said hopper into upper and lower decks, said decks having discharge outlets, a common chute to receive the coal from said decks, a chute in line with said upper deck, an opening in said chute communieating with said first named chute, a gate LIAM J.
