TAMAQUA, PENNSYLVANIA.

ORE AND COAL WASHER.

To all whom it 'may concern:

Be it known that we, HENRY W. FALKER, FRANKLIN SGHULTZ, and JOHN F. WAGNER, citizens of the` United States, said FALKER .residing at Ashland and SCHULTZ and WAGNER at Tamaqua, in the county of Schuylkill and State of Pennsylvania, have invented certain new and useful Improvements in Ore and Coal Washers, of which vthe following is a specification.

This invention relates to ore and coal Washers and more particularly to that class in the washing tank, said pan having its rear end .stepped so as to impart a rolling movement to the coal over the bed of slate and thus permit the ready discharge of the coal at the front of the machine.

A further object is to provide a novel form of gate or cradle for automatically controlling the discharge of slate'from the jig pan to the washing tank, the construction of the jigger being such as to permit the separation of both `cube and flat or flake slate. V'

A still'furthe'r object of the invention is generally to impr ve this class of devices so as to increase their utility, durability and efficiency.

Further objects and advantages will appear in the following description, it being' understood that various changes in form, proportions and minor detailsl of construction may be resorted to within the scope of the appended claims.

For a full-understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for eifecting'the result, reference is to be had to the following' description Yand accompanying drawings, inn'hieh Figure l is a side elevation partly 1n section of an ore andvcoal jigger constructed in accordance with'niy invention; Fig. 2 is a top plan view of the same; Fig. 3 isa transverse sectional view taken on the linev 3 3 `Specification of Letters Patenti Application filed February 5, l1910.

of Fig'. 1 and looking in the direction of the arrow; Flg. t 1s an enlargedgdetail vertical sectional view of the forward portion of the machine; Fig. 5 is a ldetail perspective View of the stepped end ofthe jig pan or box; Fig. 6 1s an enlarged vertical sectional view showing the manner of retaining the movable screen sections in position on the bottom of the jig'panor'box. 1-

- Corresponding and like parts are referred to inthe-following description and indicated in all the views of .the drawings by the saine reference characters. v

The machine comprises a supporting frame including upper and lower longitudinal sills 5 and 6 connected in anysuitable manner by uprights 7 and 8 preferably disposed at the opposite ends of the machine,

which engage corresponding eccentric straps 16 carried by suitable hangers or

brackets

17 and 18.

Suspended from the hangers 1i' and 18 and mounted for both vertical and horizontal movement within. the washing tank 9, is a jig box or pan 19 adapted to receive the coal and'slush from the feed spout 20, the latter being disposed atthe -rear end of the jig box, as shown.

SecuredV to the opposite side walls ofthe jig' box or pan 19, are cleats 2l having transversely alined seating grooves 22 formed therein and adapted to receive a plurality of removable screen sections :23, which latter vconstitute the bottom of the jig pan. The

position by a a rolling movement to the coal over the bed of slate in the bottom of the pan and thus to permit the ready discharge of the free coalthrough a spout 27 at the front of the pan. j

The cleats 21 at the-steps 26 are formed with intersecting lgrooves 28 so asto permit the insertion and removal of the screen l sections 29 constituting the treads and risers of the steps, it being here noted that the screen sections forming the tread and riser of each step overlap so as positively to prevent accidentaly displacement of said screen sections during the movement of the jig 15 p 'The bottom of the jig pan at the front end thereof is provided with an opening 30 through which slate and other refuse is dis-V charged into the bottom of the washing tank, the discharge of slate through the opening 30 being automatically controlled by a rocking gate or cradle 31. The gate or cradle 31 is journaled in the opposite sides of the jig pan and is provided with terminal angular portions 32 adapted to receive the correspondingly angular sockets of governor arms 33.A The arms 33 are curvedy upwardly and rearwardly on opposite sides of the jig box or pan, there being countenpoises or weights 34 slidably mounted on the free ends of the arms and secured in adjusted position by set screws 35.

Arranged within'the jig pan at the front 5 thereof is an inclined screen 36 having an attaching iange 37 and provided with a vertically disposed imperforate portion 38, the

lower edge ofvwhich constitutes a stop for the cradle or gate 31.

The upper surface of the incllned screen 36 is disposed in alinement with the base of the chute 27 so that as the coal is fed over,

the screen 36 to the discharge spout 27, the

slush and fine particles will pass through the. perforations- 1n the screen 36 and fall the openingv 30 into the washingA washing tank and carry the same upwardly through a spout 41 to a suitable point of discharge.' Y

vTheconveyer 39 is preferably in the forni of a drag, while the flights 40 sweep over a wear plate 42 fastened to thebottom 12 of the tank, said wear plate serving to prelaterally extendin flange-44 which engag a corresponding ange 45 on a casing sec tion 46, the parts being rigidly united .b bolts or similar fastening devices 47 exten ing through the tianges 44'a1id' 45, as shown. The metal at the flange 45 is extended transversely across the top of the trough 41 to form a partit-ion 48, thus to divide thel trough into superposedch'ambers 49 and 50, one of which 1s adapted to receive the upper inclined ieg of the conveyer 39, while the otherireceives a relatively short conveyer 51.

An opening 52 is formed in the end wall or partition 10 of the washing tank to permit the passage of the upper leg'of the conveyer 39, while a guard plate .5.3 is secured to the partition above'the opening 52 in order to house and protect the adjacent end of the conveyer 51. l

Secured to the side walls of the washing tank 9 are inclined' plates 54, which serve to direct the slate, slush and refusefrom'the jig pan downwardly into the path of movement of the liights on the conveyer 39, as best shown in Fig. 3 of the drawings.

Disposed at the upper end of the trough 41 yis a downwardly -inclined perforated plate "55 which receives the slate from `the conveyer 39- and directs the same into a suitable discharge chute `56,.there/being a chute 57 disposed beneath the erforated. plate 55 to-receive the slush an fine' coal passing through the perforations in said plate.

41 is secu-red An inclined plate ortrough 58 .is alsol preferably disposed at the upper end f the conveyer 50 for directing the coal on the conveyer into a chute 59 similar inco'nstructionl to the chutes 56 and 57. I

Secured to one of the transverse shafts 14 is a lwheel or pulley 60, which latter may be connected through the medium of a belt with y any suitable sourceof power, there being'al sprocket wheel :61 secured to each shaft and connected by vasprocket chain 62ifor trans- `mitting motion from one shaft to another.'

It will here be noted that the rear hangers 17 are pivotally connected at 63 with suit. able brackets 6 4 secured to the upper edge of the jig box or pan, such a construction permitting free oscillatory movement. of the pan in both a Vertical and horizontal plane,

while at the same time permitting the hangers 1 7 to be'adjusted laterally to effect the tension of the sprocket chain 62 when desired.

Keyed or otherwise rigidly secured to one of the transverse shafts l14 is a sprocket wheel 64. which engages a sprocket chain 65,

l orages? ,said sprocket-chain passing over a relatively box orjp'an, the slate will gravitate to :perforated bottoni of the pan, while the .of the screen between the: steps and largesprocket Wheel 6G secured to the adjacent driving roller 67 of the conveyer 50. A gear Wheel 68 is'secured to the other end of the roller andjiiieshcs with a correspond ing gear `Wheel G9 carried by the upper shaft.

7G of the conveyer 39, there being spaced sprocket Wheels 7l secured to the shaft for the purpose of vimparting movement to .said conveyor. l f

Thus it'will hesseen that when the material isintroduced through the spout 2G in the coal will roll over the top of the bed of slate .and-be discharged through the spout 2 at the, end of the pan, in the manner before stated, the vertical movement l'of the pan in the Washing tank causing the Water to effeet a. thorough Washing of the coal and the separation of the slate therefrom.

The stepped Aportion 26 of the pan has'u the effect of kicking or feeding the coal in a forward direction and also has a tendency to trn the light particles of slate Within the boit and present said slate edge down,

thus permitting 'the separation of dat or flake slate as Well as cube slate.

As the slate accumulates on the perforated bottom of' the pan, the Weight of the slate will open or partially open the gate or cradle 31 and allow the slate to drop by .gravityv into the bottom of the 'tank 9 so as to be taken 4up by the conveyor 39 and deposited on the inclined plate 55 for deliveryto the slate chute 56, the slush andfine coal passing throng ,55 for deliveryv to the chute 5T. A

luring the gvratory movement of the jig pan or boit, the free coal discharged through the spenti?? Will-be deposited upon the convcyer 50 and thence be directed bythe in clined plate or chut-e 58 into the coal omite 59 so that the same may he conveyed to a bin or other suitable point of discharge.
