COAL-Pick SPECIFICATION forming part of Letters Application filed June 19, 1884.

To a/ZZ whom t may conce/ra:

Be it known that I, Isaac Crinis'r, a citizen of the United States. residing at Ashland, in the county of Schuylkill and State of Penn- Sylvania, have invented certain new and useful Improvements in Coal-FickingTables; and

I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to 1o which it appertains to make and use thesame.

My invention relates to certain improvements in that class of picking-tables for separating slate and bone from coal, in which the slate, bone, or other foreign substances are i5 removed by hand. It has lor its object to provide a piekingtable which economizes labor, and is so arranged that the pickers stand or sit at the sides of the table, allowing the light to fall upon their work, and are at the same time 2o in full view of the picker boss,7 and to have the coal passing over the table divided into separate portions, only one layer thick, each picker handling only the coal immediately before him, and disposing of it without passing it to the next picker. This feature is a great advantage over the picking-tables generally used, in which the upper layer covers the impurities ofthe lower layers, and where the pickers have to handle over and over again 3o material that has already been examined. My

table is also convenient and comfortable for the pickers, and enables a smaller number of hands to do a larger amount of work much better and quicker than is possible with the old It is also simple in construction andcan be manufactured very cheaply.

The particular construction and arrangement of the various parts I will now proceed 4o to point out and describe, reference being had to the accompanying drawings, in wliich- Figure lis a plan view of a coal-picking tableembodying my improvements; Fig. 2, a longitudinal'section of the same; Fig. 3, a vertical cross-section of said pickingtable, and

Fig. 4L a detail showing one of the deflectingwings.

Referring to said drawings, A is the main chute or telegraph, inclining from top to boto tom, the sides of the same pitching toward ING TABLE.

l their outer edges and forming the pickingtables B. These tables can be raised at their lower ends, if desired` as shown in dotted lines at a, Fig. 4, thus forming a series ot' steps on the sides of the main telegraph.

G are curved deflecting-wingsextending inward and upward from the outer sides of the tables B toward the longitudinal center of the' chute, but leaving the same openl from top to bottom. The two lower wings, C', extend en- 6o tirely across the bottom of the chute or telegraph. Said wings C also separate thetables B. l) is the coal-chute arranged underthe main chute A, and having the same downw-ard incline as chute A. Said chute D is provided l with upwardlyeurved sides d d, and terminates in the horizontal table d.

E E are a series of platforms or steps so arranged that each step is at kthe side of and opposite a picking-table, and rlower than said 7o table.` On these steps are placed removable stools for the pickers, and when desired these stools can be removed and the pickers can stand upright upon the steps E E. The pickers are thus able to work at the sides of the 7 5 tables and main telegraph. The picker boss,

l standing at one end of the main telegraph, can readily superintend the work done, and the pickers being at the sides of the table instead of in the middle of the main telegraph, and8o one above the other, as is the case in most pickin g-tab'les, the table can easily be arranged so that the light will fall directly upon the Inaterial to be picked as it comes before the pickers. On the outer sides of the platforms or steps E E are inclined bone-chutes F and slatechutes G, said chutes terminating in the tables f and g.

I are bonetrou ghs, and K slate troughs, leading from the picking-tables B to their respect- 9o ive chutes. v

His a return, by means of which the coal is transferred to the coal-bins, and H H are returns for carrying the slate and bone to the hoppers or bins, andare of the same construc- 9 5 tion as the return II.

Across the bottom of the tables d', j', and g are seats h for pickers who give the coal, slate, Sie., afinal inspection before it is transferred to the bins or hoppers.

IOO

My table is used ztslollows; The pickers .sit orstand nt the Sides ot' the tables B. The coal enters from the screens zit the top ot' the mitin telegraph, and, sliding down the saine, comes in contact with the delecting-wings C, and is lnoved in tt'singlc layer upon the picking-tables B. The coul thus being divided into several streznns and presented to the picker in :L single layer, the impurities cnn readily be detected and Separated f'roni Suid coul, which is dropped into the coal chut e D. The slate and bone heilig thrown into thc proper troughs are conveyed to their resl'ieetive chutee. The. outward pitch ot' the tables B renders it very easy to inove the coal toward the piekers. Then the coal, bone, slate, ce., rcnehes the tables d, f, und y, it is subject ed to n, tinnl inspection :ind picking before it goesto the bini; or hoptwrs.
