JAMES H. SHAFER AND THEODORE CORNUELLE, OF MADISONVILLE, OHIO.

SEPARATOR AND WASHER.

To all whom it may concern:

Be it known that we, JAMES H. SHAFER and THEODORE CoRNnnLnn, citizens of the United States, residing at M adisonville, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Separators and lVashers, of which the'following is a specification.

Our invention relates to separators and washers for material such as gravel, coal and the like.

The object of our invention is to provide a device for thoroughly sitting or washing material through a screen with the aid of water, thereby separating the coarse material from the fine and automatically discharging the coarse material from one outlet and the fine'material from another outlet.

Another objectof our invention isto provide a machine which may be fed rapidly in large quantities, and which automatically separates and washes the material deposited therein.

Our invention consists briefly in a receptacle, a. cylindrical screen or wiremesh cylinder suspended therein and submerged partly in water, feeding mechanism communicating with said screen, means whereby said screen is rotated, an outlet for the coarse material, and mechanism whereby the fine material is withdrawn from said receptacle.

Our invention also consists in certain novel parts and combination of parts and in the details of construction herein set forth and claimed.

in the accompanying drawings which serve to illustrate our invention: Figure 1 is a perspective view. Fig. 2 is a side clevation of same, with parts removed and the casing broken away. Fig. 3 is a rear elevation.

In the embodiment of our invention as illustrated and which shows a preferred construction, 1 represents a receptacle, or tank adapted to hold water,- in which the wire meshcylindrical screen 2 is suspended. Vertical standards 3 and 4 are provided on each side of the receptacle ortank 1 and are connected at their ends by cross bars 5 and 6 on which are mounted journals 7 which are adapted to carry a driving shaft- 8. Mounted on the driving shaft 8 aresheaves 9, a-

sprocket 1O thereon at one side of the machine and a bevel gear 11 thereon at the other end of said shaft.Horizontal bars 12 are mounted upon the cross bars 5 and G Specification of Letters Patent. PatentedJ 1y 23, 1912, Application filed September 20, 1910. Serial No. 582,840.

and are adapted to carry a shaft'13 at one end thereof which has mounted thereon a beveled .gear 14 which is adapt-ed to mesh" 1' with the beveled gear 11 on .the driving shaft 8. i

The wire mesh cylindrical sc'reen2 is provided with aframe work 2 orrings 15 which are provided withgrooves 16 to receivechains 17 also the chains are adapted to pass around sheaves 9zmounted upon the dzivingshaft 8, the cylindrical and end spiders 4screen 2 being suspended upon said chains and rotated thereby when the driving shaft- 8 is operated. Mounted atv some suitable place on the framework of thereceptacle 1 and journaled injournals 18 of theshaft 19 are flangedrollers 20 mounted thereon for the purpose of forming a guide and retainer for thecylindrical screen 2, thereby prevent:

ingsaid cylinder from wabbling and jgetting out of position.

Ashaft 21 is mounted in the lowe: part i of the receptacle ortank 1 at one end thereof .below thecylindrical screen 2 and isprovided with journals 22 mounted at some suit able point on the receptacle ortank 1. Mounted upon theshaft 21 aresprockets 23 adapted to receive asprocket chain 24 having paddles o'rdrags 25 thereon. --Anoperating shaft 26 is mounted at the upper opposite end of thereceptacle 1 and is'also provided withsprockets 27 around which thesprocket chain 24 passes. Thisshaft 26 'is also journaled in suitable journals 28 mounted in a. suitable manner upon the reccptacle l. Thechain 24 with paddles 25 a thereon constitutes an endless conveyer or drag whichremoves/the sifted material from the receptacle-1. At the end of theshaft 26 is mounted asprocket 29 which'is in alinement with the sprocket 10 mounted uponthe driving shaft 8. Asprocket chain 30 connects these two sprockets 10 and 29 and thereby forms a means of driving the shafts 26and21.-' i

The operation thus far is readily seen from the illustration in Fig. '1, the driving shaft 8 beingrotated, operates the cylindrical screen,2 also operating the sprocket 29', which operates the convever or drags 25 in the proper direction, the drags forming a means of removing the sand'and' fine "material from thereceptacle 1 and pushing it up above theboard 31 provided at the top of thereceptacle 1.

The feeding mechanism is provided on the side of thereceptacle 1 and comprises a hopper ortrough 32 having av movablenotched floor 33 which is given a reciprocating motion by mechanism which will now be described. Thetrough 32 may be mounted as shown upon brackets 3% on the sides of thereceptacle 1, and arms'35 extending therefrom to which thesmaller brackets 36 are attached. A dislt orcrank wheel 37 is provided on and driven by theshaft 13. Arocker shaft 39 is provided below thefeed trough 32 and is mounted injournals 40 on the sides of thereceptacle 1. Arocker arm 41, is mountedupon said shaft atone end thereof and connects to rod. 38 which is eccentrically connected to thedisk 37, thus imparting an oscillatory motion to the rocker arm all when the'disk 37 is operated. Arkother rocker arm 42 is mounted on theshaft 39 directly under the central portion of thefeed trough 32 and is connected to themovable bottom 33 of thetrough 32 by means of a pitman as. Therocker arm 42 being fastened tight to theshaft 39 operates thepitman 43, thereby operating themovable bottom 33 of thefeed trough 32 and imparting a reciprocating motion to the bottom of thetrough 32.

Thebottom 33 is provided with a groove.

into which the sides ofthetrough 32 enter and thereby hold themovable bottom 33 in position during its reciprocating motion.

.l-ollcrs 44 may be'provided and mounted injournals 45 on thearms 35 upon which thebottom 33 of thetrough 32 may rest, thereby reducing the friction of thebottom 33 when it is being operated.

Thetrough 32 is provided with an extension .32 which extends into the side of thereceptacle 1 and projects a short distance into the inside of thecylindrical screen 2,

thereby insuring that all the. material put into thetrough 32 will eventually deposit into thecylindrical screen 2. An outlet trough or chute 4:6 is provided at the other side of thereceptacle 1 and projects into the other side of thecylindrical screen 2 through the annular opening in the ring orspider 15.

lllounted on the inside of thewire mesh cylinder 2 and at the end nearest theoutlet chute 46 we provide a series of inwardly extendforming a means of removing said coarse material from the cylindrical screen.

A water supply pipe 4-8 is provided at some suitable portion of the machine which is adapted to supply water to the receptacle l and is also adapted to wash the material which has been deposited into the meshcylindrical screen 2. The outlet of the pipe is preferably placed above thecylindrical screen 2 and discharges water into said cylinder, thereby washing all fine material through the wire mesh of the cylindrical. screen. 2 down into thereceptacle 1 which is adapted to be practically filled with water. Anoverflow 49 is provided in thereceptacle 1 near the top, thereby keeping the water in thereceptacle 1 at a constant level.

The portion of thereceptacle 1. which lies underneath thedrag chains 24 is filled with line sand in order to provide a soft bed for thedrags 25 to operate upon.- The sand or fine material is constantly falling through the wire mesh screen of thecylindrical screen 2 and settling in the bottom of thereceptacle 1, and is being dragged out by means of the drags or paddles 25 upon the incline surface of the embankment ofsand 50, as best shown in Fig. 2.

The operation of the device is as follows: The rough material such as sand or coal is dumped into the feedingtrough 32 and is thereby fed by means of the reciprocating movable floor in said trough gradually into thecylindrical screen 2, which being rotated gradually sifts the sand, with 'the help of the water supply constantly flowing into thereceptacle 1, through themesh cylindrical screen 2. The coarser material remains in thecylindrical screen 2 and gradually works to the other end. thereof Where it enters the pockets between the extendingfianges'of wire mesh 47 and is carried by said extensions up to thechute 46 at the upper end of thecylindrical screen 2 and is thereby de posited into the chute and carried by gravity to the outside of said receptacle. "While this is being done, the dragging device is con stantly dragging the sand from thereceptacle 1, thereby forcing it out over the edge of thereceptacle 1, thedrags 25 being driven in the direction of the arrow shown in. Fig.

lhe bed ofsand 50 is provided in. order to allow thepaddles 25 to have a surface and yieldab'le bed to drag over so that a stone hard particle which might have strayed into the bed will not destroy the paddle which it engages.

This device is a positive separator which completely separates the sand from the coarse material, and by varying the mesh from the smaller or inlet end l the cylin der to the larger end, the sand may be graded from very fine sand to very coarse sand.

The device is adapted not only for sepa- 1 be made Without departing from its spirit and scope, and We do not Wish to be confined llO'll'lB exact details shown.
