JOSEPH 'I'. NORMAN, OF NANTICOKE, PENNSYLVANIA, ASSIGNOR T0 NORMAN PICKER CO., 0F NANTICOKE, ENNSYLVANIA, A PARTNERSHIP.

OSCILLATING SLATE-PICKER.

To all whom it 'may concern.'

Be it known that I, JOSEPH T. NORMAN, residing at Nantieoke, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Oscillating Slate-Pickers, of which the following is a specification.

My invention is an improved apparat-us for separating coal and slate, and it primarily has for its object to provide an apparatus in which a relatively large number of successive separations can be effected in a machine of moderate size.

The invention also has for its object to provide an apparatus in which the tiow of material is brought to a complete stop between each separation; to provide a machine wherein the material flows at a uniform speed throughout the machine; to provide an apparatus in which the material on one deck cannot catch up with or bank up onto that of a succeeding deck; to provide an apparatus that cannot be overloaded and will not clog up.

In its general nature, the invent-ion comprises an oseillatable frame which supports a series of decks that are located one above another, alternate decks being directed in the same direction to form two sets of decks, one set discharging at one side of the machine, and the other set discharging toward the opposite side. Each deck has a separate coal and slate discharge, the slate discharge -of a deck being arranged to deposit the slate and any coal that falls through with it, onto the next deck below for further separation, while the separated coal is discharged directly from the machine.

More subordinately the invention includes those novel details of construction, combination and arrangement of parts, all of which will be first fully described, and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which z- Figure 1 is a perspective view of a preferred form of the apparatus. Fig. 2 is a central vertical longitudinal section showing the manner of operating the machine. Fig. 3 is a cross section on the line 3 3 of Fig. 2. Fig. 4 is a cross section on the line 4 4 of Fig. 2. Figs. 5 and 6 are detail views of parts of the invention.

In the drawings like numerals of reference designate like parts in all the figures.

Upon a suitable supporting base 1, on which bearings 2 are mounted, the main supporting shaft 3, is journaled. The shaft 3 carries an oscillatable frame 4 which is composed of vertical channel irons 5, those on one side being connected to those on the other side by cross braces 6, the channel irons at one side being connected to each other by longitudinally extending braces 7 which are also connected to the central vertical support 14".

1n my apparatus a plurality of separating decks are mounted on the frame 4 in vertical succession and alternate decks discharge in one direction while the remainder discharge in the other direction. As the construction of each deck is substantially the same, a description of one will be sutcient.

Each deck comprises a chute-like member consisting of sides 9 and a bottom 10. The bottom 10, at the entrant end of the deck, is curved back as at 3 to form a receiving pocket, and the bottom 10 and sides 9 are braced by a suitable reinforcing iron 11.

The sides o-f the chute are made in two sections hinged together as at 29, and the bottom 10 is also provided with an adjustable ta le 13 of slate or other suitable material which is held in the recess 12 of the forward end of the bottom 10. The recessed portion 12 of the bottom is made separately from theremaining portion of the bottom, and the two parts are hinged together as at 14 to enable the table 13 to be raised o-r lowered as desired. The deck is supported in the frame 4 by laterally projecting lugs or feet 15, which are bolted at 16 to the side bars 7, which bars 7 may be slotted as at 17 to receive the bolts 16 and for purposes of adjustment. In order to adjust the deck longitudinally, the underside is provided with rack portions 18 that engage pinions 20, on a shaft 19 which is mounted in the frame 4, and carries a ratchet 21 to coperate with the pawl 22 and prevent the shaft 19 from turning under normal conditie-ns. rEhe shaft 19 is provided with a turn-stile 23 by means of which it may be turned when the pawl 22 is disconnect-ed from the ratchet 21. The second deck from the top and those below it are provided with discharge chutes 30 adjacent their entrant ends to discharge the coal from the next deck above the chutes 30, being secured at 31. The table 13 is adjust-ed on the hinge connection 14: by mea-ns of arms 25 that are carried on a shaft 224;, which is mounted in the frame ii and carries a ratchet 2G to coperate with the pawl 27. The shaft 24x; is also provided. with a turn-stile 2S by means of which it may be turned when desired.

The frame et is adapted to be oscillated on its axis by any suitable means, such as a crank and pitman arrangement, best shown in Fig. 2 of the drawings, by reference to which figure it will be observed that 34 indicates a driving shaft that carries the pulley 8G, which receives power from any suitable source. The shaft also carries adjustable cranks 35 that are connected to the f fame 4 at by the pitmen 37 designates the coal piles, and 38 the slate pile, in Figs. l and 2.

In order to adjust the gap between the table 13 and the corresponding discharge chute 30, the shafts 19 may be turned to move the decks longitudinally to increase or diminish the gap as may be found desirable.

In operation, the decks are adjusted to provide suitable jump spaces through which the heavierI slate may gravitate, while the lighter coal jumps the space and deposits on the discharge chutes 30. The operator shovels or dumps the coal and slate onto the upper deck 8 when the apparatus is in the position shown in Fig. 2, or places the material on the entrance or receiving deck in any desir-ed way. The movement of the shaft Sil will impart oscillation to the frame 4f to move it from the position of Fig. 2 to an oppositely inclined position, and vice versa. Now as the frame l is rocked from one position to the other, the material on the alternate deck will slide off, the slate and some of the coal carried with it will `drop into the pocket 8 of the nexty below deck, while the coal will jump the gap onto the chute 30 and be discharged from the machine. As the machinev is rocked back, the material on the second deck from the top will be shot onto the third deck from the top, the separated coal passing out while the slate and coal carried by it, will drop through onto the third deck and so on. The slate is finally discharged in a pile 38 through the gap in the lowermost deck, intermediate the coal piles 37.

It will be understood, of course, that a fresh supply of lcoal and slate is deposited on the upper deck at each oscillation of the machine so as to keep a constant stream of material in the machine. It will also be noted that the speed of movement of the mass on each deck is the same, that is to say, the mass on one deck does not move any faster than the mass on the other deck, and the movement of the mass is entirely arrested as the apparatus reaches the limit of its inclination in each direction, as will clearly be understood by reference to Fig. 2 of the drawings.
