SHAKER-PLATE FOR ORE AND COAL LltZASd.

To all whom it may eoncern Be it known that I, Mosns JAMES, citizen of the United States, residing at Lansford, in the county of Carbon and State of Pennsylvania, have invented certain new and useful Improvements in Shaker-Plates for Ore and Coal Washers, of which the fol- 1 lowing is a specification. I

T his invention relates toimprovements in the shaker plates of ore and coal Washers.

It is one aim of the invention to provide a shaker plate so formed that in operation it will act to effectually spread the material '7 be thrown up from the plate to a greater or ess extent, as distinguished from being merely shifted back and forth upon the surface of the plate,'as would be the case if a plane shaker plate were employed. This agitation of the material of course serves to bring dlfferentportions of the mass into contact with the surface of the plate, sue-- cessively, thereby insuring ing of all port ons.

thorough wash-- to strengthen the plate and prevent its sagging, which is likely to occur in the use of a plane plate.

Another aim of the invention is to so'constructand arrange the riflles that the material will be retarded inits movement over the surface of the plate, thereby further ing suring thorough washing of the material.

Still further the invention has as its aim to provide .a riftleplate of such formation that it may be employedfin treating ore or coal Whether in wet or dry conditlon, In the accompanyin'gdrawmgs; Figure 'l i is a plan View of the shaker plate embodying the present invention Fig. 21s a sec j e be e their ends opposlte their merging. ends, the

Corresponding and like parts are referred to in thefollowing description and indicated in alljthe views of the accompanying drawingsby the same reference characters.

The invention also contemplates so form 111g and-arranging the rlifles 1n the plate as The rifiieplates are of course arrangedin a series within the shaker frame, and inasmuch as all of the plates areof the same construction, a description of'one Will suffice forall, 1 w

is indicated by the dot and dash line 1n F1g.1, and theriffles formed in the plate j are arranged, in a manner to'be presently described, in a certaln definite relation'to th1s line, the r ffles belng located Within a 'certaindefinite area, the boundary lines of, which are spaced inwardly from the edges of I the plateso that the edge portions of the plate are leftplane, whereby to serve'as attaching and c0nnec'tingflangesr One'of these edge portionsylocated at one longitu-aopposite edgeportion is indicated by the numera -let and is preferably slightly-wider 1 than the edge portion?2 and formedv ith:

two series of 0 enin s 5. Each lateraledge portion of the plate is indicated atG and.

is formed with'openings 7.

, The riffles are formed by stamping the 1 plate with alternating ridges" and valleys at I I each side of its front to rear median line; The rlflles are arranged in two series, one 10' cated" atjeach f side of the front to rearmedian, line of'the plate and the arrangement in'the two'se'ries is the same.- Certain of the riflies of each series are indicated the numeral 8 and the other riffles of each series are indicated by the numeralti. Corresponding ones of the first-mentioned Elfl'lQS of the two series'tm'erge or unite at their inner ends along the median'line, and the said rifflesextend in opposite directions from this line diagonally, from-the plate and in thegeneraldirection of the adjacent corner. 'of-the plate, the rlffles of each series being, however, par'allelfto each :other and being furthermorepreferably at right angles to corresponding rilflesf of the iotherseries. At

rilfles merge into the ear-face of the plate,

It willlalso be apparent-by reference to Fig.

. 1 that the riffles' of theftwo series diverge in. the directionqoffthe edgeportion 4 of the plate. lThe riifles 9 of eachseries extend paralljel to the riflies 8. of the same series but do I wardly therefrom.

not merge at their adjacent en .s, they being arranged diagonally within the corner of the plate neXt adjacent which the longer ones of the ritlles 8 are located, and being gradually decreased in length as they, in the series, approach the said corner. Inasmuch as the rifles 9 of the other series do not merge or join each other, they inerge at both ends with the surface of the plate. l he shaker plate is provided throughout its riflle area with nunicer of perforations 10 through which the water may drain during the washing operation.

The manner of arranging the plates within a shalrer frame is clearly illustrated in Fig. 3 of the drawings, the numeral 11 indicating the frame in general and the said frame being of the ordinary form and provided at the lower edges of its sides with L angle iron bars 12 which have a vertical secured to the inner face of the said side and horizontal. flange projecting in- The lateral edge por tions 6 of the plates are bolted or otherwise secured to the horizontal flanges of the angle iron bars, and bolts are passed through the openings 3 and 5 i the overlapped edge portions 2 and 4; the series plates and through cross bars 13 secured at their ends, to the horizontal flanges of the angle iron bars and extending transversely beneath the said side portions 3 and 4-. By reference to the said 3 it will be observed that the plate, located t is intake end of the frame, which end of the frame is indicated by the numeral 15, is so arranged that its riffles will converge or be inclined toward that end of the frame. he next plate in the series is arranged in cr ed position, however, and this relative arrangement of each two of the plates is continued throughout the series. It will now be apparent that when the mate rial is introduced into the shalrer frame, it

will be separated and agitated, and due to the fact that the riiiles or the second plate in the series of plates diverge toward the outlet end of the frame, the niaterial will be spread and separated at each side of the front to rear niedian line ofthe frame. As he material passes onto the second plate in the series, the mass is concentrated or gath red toward the said longitudinal inedian line of the frame, and as it passes onto the third plate of the series, it will again be spread in the sane manner as when passing over the first plate of the seies. lit will be understood, of course,that the riilles will serve to up from the surrace of the plates andfthat the material is shifted'not only back and forth but also from side to side, so that it is thoroughly agitated and more effectually washed would be possible by the use structed throw the material 01 a plane perforated plate. will also be understood that the valleys of riflies will tend to collect and retain the water, thereoy preventing the same passing too quickly or freely through the opening 10.

It will be observed that the plates embodying the present-invention have plane or marginal portions, and it will further be observed by reference to Fig. 3 that when a number of the plates are assembled in series with their said marginal portions overlapped, distributing channels will be pro iced between the said plates.

Having thus described the invention, what is claimed as new is:

l. in a device of the class described frame, a alurality of shaker plates arra within the frame, each plate being provio at each site of its median line with a series of riflles, tlie rifties of the two series upon each plate meeting at the median line of the plate and the rifiies of one series extending an angle with respect to the rifles of the oth r series, the plates being arrange within the frame with the riflies of the two series alternately diverging in the direction of the opposite ends of the frame.

2. A shalrer plate of the class described haying marginal portions and formed within th bounds of tlie said portions with a raised rilile dressing, certain of the ginal portions being constructed to overlap similar portions of the other ones of the plates when a number of the plates assembled ged ed in series, and being furtl er conto permit of the said portions being secured together in their overlapped relation and adapted with a mating plate to form distributing channels between said plates.

3. A. shaker plate of the class described ha ing flat marginal portions and formed within the bounce of the said marginal portions with diagonally extending raised corrugations arranged in series at opposite sides of the longitudinal median line of the plate, the corrugations of the two series converging toward and meeting at the said line and each terminating at one end at the marginal portion at one side of the plate, the front and rear marginal portions of the plate being connected to overlap and be secured to similar portions of other similarly constructed plates when a of the plates are arranged in a series and adapted with a mating plate to form distributing channels between said, plates.
