NON-ATTRITION PROCESS OF-AND APPARATUS FOR WASHING AND SORTING COAL.

Application filed ma 11, me. Se1'1alNo.96,774.

To all whom it may concern:

Be it known that I, HENRY ADAMS, a citizen of the United States, residing in New. London, in.the county of New London and State of Connecticut have invented certain new and useful Improvements in Non- Attrition Processes of and Apparatus for \Vashing and Sorting Goal, of which the following is a specification.

This'invention relates to a process for sizing and separating minerals and ores OI different specific gravities, and especially anthracite coal, and the apparatus for carrying out such process.

One of the main objects of the present invention is to provide a process whereby the finer elements of a quantity of mineral, ore or coal that is being sorted will becatrried with jets of water or the like into troughs separated fromone another, each provided for one of the series of jets of water, and the heavier elements will be dropped into lower compartments, the heavier of such heavier elements dropping into the compartments nearest to the inlets of such jets while the lighter of such elements drop into the compartments farther away' from such .For carrying out the process, an apparatus is disclosed particularly adapted for grading coal. By means of this apparatus, it will be seen that the heavier particles may be removed without first draining the water by which they have been washed, and only the receptacles or troughs for the lighter elements require drainage of water before removal.

These and other features, capabilities and advantages of the invention will appear from the subjoined detail descri tion of one specific embodiment thereof il ustrated in the accompanying drawings in'which- Figure 1 is a fragmental front elevation of the apparatus, partially broken away.

Fig. 3 is a sectional view of the portion of the apparatus shown in Fig. 1 as used for separating the several grades of coal from one another.

In the portion of the embodiment shown in Figs. 1 and 2, a main housing A is pro- Specification of Letters Iatent. I

vided preferably of long1narrow construc- 11 and provided tion having a rear wall 7 with three elongaterhialetslots 12, 13 and 14 and front wfliid ii lflaving three elongated outlet slots 16,11? ahd 18 of greater widths than the slots 12,13 and 14; a roof member 19 having an elongated opening 20 therein adjacent to the rear wall 11; and a floor member 21'provided with partitions 22 extending upward therefrom to form the troughs 23. w

Extending down from the elongated opening 20 in the roof member 19 there are flange portions 24 converging downwardly to form a suitable mouth for receiving the coal to be graded preparatory to feeding the same into the housing A. Extending along the slots 12, 13 and 14 are the tubes 25, 26 and 27 respectively each connected to the stand pipe 28 by suitable connections 29, 30 and 31 respectively. The connections 29, 30. and 31 are each provided with a control valve 32. The stand pipe 28 -is suitably connected to a reservoir 33 to which reservoir 33 the water or is pumped by the pump is also provided with valve 35.

.The outside of the front wall member 15 is suitablyv equipped with troughs 35, 36 and 37 each secured adjacent to the lower 34.. The reservoir a suitable controledges of the openings 16, 17 and 18 respectively. The troughs 35, 36 and 37 have their outer wall members extending upward beyond the upper edges of the openings 16, 17 and 18 and their lower portions extending at an inclination to the horizontal to facilitate the water or liquid that may collect therein. v

For conveying the coal to be treated in the housing A to the opening 20, suitable elevator L is provided suitably guided by the sprockets 38 and provided with buckets 39 or the like.

In the troughs 23, suitable receptacles 40 which may be movable'conveyers are provided.

The tubes 25, 26 and 27, are provided with suitable openings whereby water that is conveyed to such tubes may be discharged therefrom through the openings 12, 13 and 14 across the interior of the housing A to the o ehings 16, 17 and 18 to be discharged there rom.

such as perforations,-

a suitable liquid The portion of the embodiment illustrated in Fig. 3 consists essentially of a housing A similar to the housing A, having a rear wall 11 provided with openings 12, 13 and 1ft; a front wall 15 provided with openings 16', 17' and 18; a roof member 19 provided with the openings 20- and a partition member 22' extending parallel to the wall members 11 and 15 and dividing the bottom of the housing A into two trough members 23'.

.On the Outside of the rear wall member 11 tubes 25, 26' and 27 are provided which similar to the tubes 25, 26 and 27 are also connected to .a reservoir and pump by means of which water may be fed to such tubes 25, 26' and 27'.

As i ustrated in Fig.2 the openings 16,

17 and 8 are disposed at a lower level than the openings 12, 13 and 14, for this purpose,

the dischargeperforations of the tubes 25, 26 and 27will befset accordingly. It will also be seen that ' theppenings 16 and 18 are disposed at lower (levels than their cooperating openings 12 and 14 relative to the lower level of the opening 17.to its 006perating 0peningf13. This is provided to exercise varijhus degrees of-impetus by the water jets on the coal being treated.

Disposed above the opening 20 there is provided a suitable hopper 41 to receive the a coal from the buckets 39 of the elevator L preparatory to phargino the same into the mouth of thehi msing A? On the outside of the front wall 15', in-

clined troughs 35', 36' and 37 are secured adjacent to the Qpeni'ngs 16, 17 and 1.8 respectively.- ,The levels of the openings 16', 17 and 18 relative to the openings 12, 13' and 14. are similar to the difference ,in levels of the openings 16, 17 and 18 relative to the openings 12, 13 and 14 of the housingA.

Secured-to the inner side of the roof member 19 the inwardly extending flange 'portions 24' are secured converging toward one another to provide a mouth to thehousing A similar to the-mouth of the housing A.

Disposed above 'the opening 20 is provided a suitable hopper 41 to receive'the coal proprietary'to discharging.the same .iiltu the mouth of the housing A; such hopper 41 receiving the coal from the buckets of" an elevator passing across the same similar to the buckets 39 of the elevator L of the housing A. p v

The steps of the process consist substantially of the following: The coal after having been broken to suitable siies and before the slate and other foreign material have been removed therefrom is discharged into the mouth of .the housing A. The slate having a greater specific gravity than coal when coming into contact with jets of water or the like discharged by the tubes 25-,

. 26 and 27 will not be deflected thereby and is permitted to drop into the trough 23' adjacent to'the rear wall member 11.. The coal therefore will be deflected by such jets of water to drop into the trough 23 adja cent to the front wall member 15', and the lighter elements contained in the mixture such as coal dust, and ver coal will be carried with t e jets of water into the troughs 35', 36 and 37 the heavier of such elements naturally being conveyed to the lower trough 37'. In this we the 'slate willbe separated from the coa and fine grades of some of the finer grades of coal separated from the Heavier grades, such. finer grades settling in {he troughs 35, 36' and 37-1 ready for remove after the water has been drained 'from such troughs.

Thereupon the coal contained in the trough adjacent to the front wall member 15 is conve ed .to the buckets 39 of the elevator L to a discharged into the housin' A for further sortin As the coal drops rom the .moutluof the ousting A the force of the jets next lighter grade of coal, for instance the chestnut grade, will be sufficiently deflected by the jets of water to drop into the intermediate receptacle 40 and the grade lighter than the chestnut as for instance pea grade will drop into the receptacle 40 adjacent to the front wall member 15. The still lightergrades including coal dust and like that may still be contained in the mix- I ture conveyed to the housing A will be carried with the jets of water according to them specific gravities and deposited in. the

troughs 35, 36 and 37 from which they may be removed after the drainage of the water from such'troughs.

. It is obvious that various changes and modifications may be ade to the steps of the process of the ap aratus for carrying out such process without departing from the general spirit of the invention.
