Applicatio'ii mea November 24, 1919. serial No. 340,299,

To all eli/0m muy concern.'

Be it kno-wn that` I, JosnrH P. VOGEL, a citizen of the United States, and resident of Pittsburgh, in the county of Allegheny and State oi? Pennsylvania, have invented a new and useful Improvement in Picking rlables; and do hereby declare the following` to be a full, clear, and exact description thereof.

ii) My invention relates to picking-tables for use in connection with mining operations where the coal or other mined product has certain impurities which have to be removed before the coal is delivered into cars for shipment. l

The object of my invention is to provide a picking-table in which coal of different grades may be deposited on the same annular table, side by side and yet kept in l0 individual piles, and the refuse such as rock and bone picked therefrom from opposite sides and delivered by chutes to the points desired, while the picked coal is automatically discharged from the table, one grade going to one point and another grade to another.

To these ends my invention comprises the novel features hereinafter set forth and claimed. p :io In the accompanying drawings, Fig. 1 is a plan view of my improved picking-table;

Fig. 2 is a view partly in section of my improved table showing the mannerof delivering the coal thereto and discharging it therefrom; and Fig. 3 is an enlarged cross-section on theline 3 8 of Fig. 1.

In the drawing the numeral 2 designates a suitable platform on which are mounted pedestal bearings 3 within which are mounted the flanged idler-wheels 4.

The table 5 is annular in form, and secured to the bottom of said table is the annular inverted rail 6 which rests upon the treads of the idler-wheels 4.Y Y

The table is divided into two compartments 7 and S by means of the partit-ion 9, the compartment 7 being for nut coal and the compartment 8 for lump. For convenience in picking it is desirable to have the nut and lump coal separated in this manner, for it is much easier to pick out the bone and rock from coal of a certain grade than where coal of different grades are mixed together.

The inner and outer edges of the table are provided with the stationary annular flanges 10.-

To provide a smooth surface'for the plow (hereinafter specifically referred to) to work on `in the nut compartment 7 a supple` mental bottom-plate 11 is provided and which does away with the obstruction which would be offered by the flange of the angle 9 forming the partition. i

To provide for the rotation of the table a rack 12 is secured to the lower side of the table and a clrivingpinion 13 meshes with said` rack, the connections between said pinion and the suitable motor being so regulated to drive the table at about 50 feet per minute at its center line.

Plows 14 and 15 are provided, said plowsY being pivo-tally mounted so as to be swung into or out of position. The plow 14 is adapted to operate on the nut coal and is projected into the compartment 7 while the plow 15 isadapted to act on the lump coal and is projected into the compartment 8.

A chute 16 is located in position to receive the nut coal discharged by the plow 14 and aloading boom 17 is provided to receive the lump coal from the chute 15a plowed by plowl from the compartment 8 of the table. 1 Where it is desired to deliver the nut coal to the loading' boom 17 for the lump coal, a fly gate 18 is provided in the nut chutev 16 and b v opening said the nut coal will be delivered by chute 18a onto the loading booml? to be delivered together with the lump coal at a common point.

The chutes 19 and 20 deliver the lump and nut to their respective compartmentson the picking-table, the lump in the apparatus illustrated being delivered to the outside compartment and the nut to the inside compartment. i

The pickers stand on'the inside and outside of the table and the refuse is picked and delivered into the chutes 21, said chutes communicating with a. common refuse hopperrnot shown.

By having a partition separating the lump from the nut coal on the table there is no liability of the same becoming mixed and consequently when the coal is discharged by the plows from the table the lump coal will go to the loading boom `17 while the nut coal will be discharged into the chute 16.

What I claim is: Y

1. An annular picking table, means for ce Y rotating saine7 means for delivering different grades of coal to diierent Zones of said table, a loading boom, means for delivering coal from one of said zones to said loading boom, means for delivering the coal 'from the other zone in a dii'erent direction, and means for changing the means of direction of the coal from Said last named Zone #o said loading boom.

2. An annular picking table, means Jfor rotatingthe same7 means for delivering' different grades of coal to different zones of said table, a chute, means for discharging one grade of coal from one zone of said table to said chute, a loading boom to re- 15 ceive coal from said chute, a second chute, means for discharging coal from another zone of said table on to said second chute, and a gate in said second chute whereby the material delivered to said second chute may be delivered directly on to said loading boom.

In testimony whereof I, the said JosnrH P. VOGEL, have hereunto set my hand.
