STEPHEN J'. KERRIGAN, OF GILBERTON, PENNSYLVANIA..
SLATE-JIG.
Specification of Letters Patent. Application filed November 24.-, 1906. Serial No. 344.907.
Patented Sept, 3, 1907.
To all whom 'it may concern:
Be it knownthat I, STEPHEN J. KERRIGAN, a citizen of the United States, residing at Gilberton, in the county of Schuylkill and State of Pennsylvania, have inventedv new and useful lmprovements in Slateligs, of which the following is a specification.
The invention relates to an improvement in slatejigs, and particularly to a screen adapted for use there with.
The main object of the present invention. is the production of a jig and screen of the type described'constructed and arranged for the effective separation of the slate from the coal.
The invention in its prefelred form will be described in the following specification, reference being had particularly to the accompanying drawings, in whiCh:-
Figure l is a perspective view of a jig screen constructed in accordance with my invention, Fig. 2 is sectional view of the same on line 2--2'of li'ig. l.
Referring to the drawings it will be noted that my.
improved screen comprises a metallic plate l having upwardly turned marginal side edges 2 to provide flanges whereby the screen may be connected to any preferred form of jig operating mechanism. The horizontal portion or plate proper of the screen is formed with a plurality of openings 3, arranged at ari-angle to va line longitudinally and centrally 'of the plate. By preference these openings are arranged in transverse rows, extending alternately at opposite angular rela tion to said central line, so that the openings in one row, being respectively parallel to each other in themselves, extend at an angle reverse to the direction of the openings in the next row. It will also be observed that the ends of the openings in one row are arranged between the ends of the openings in theapproximate row. By this construction the plate is provided with a series of openings inclining reversely in rows, and arranged in alternate or staggered order longitudinally of the plate. The openings which are approximately triangular in shape arc formed by stamping lfrom the material to leave the cut portions integral with the plate, said cnt portions being bent upwardly from their connection with the plate and at an incline to its surface to provide sheds 4 covering the openings. The sheds are arranged to projectthe greatest distance from the plate at their widest or base ends, thereby affording the maximum access to the openings 3 at these points.
In use the coal andslate will be caused to travel longitudinally of the jig, the slate owing to its comparatively thin or plate like structure finding its way readily through the openings 3, while the coalowing to its round or lumpy structure will pass over the sheds of said openings and be delivered from the passage end of the screen comparatively free from slack. l
Owing to the inclination of the sheds 4 with relation to the plate it will be obser Jed that the slateparticles are directed through the openings. while passing longitudinally of the screen.
Having thusdescribed the invention what is claimed as new, isz- A jig screen comprising a flat plate with vertical upturned opposite sides, the body of the plate between the sides having transverse parallel rows of oppositely iuclned triangular' shaped openings struck therefrom, said openings being so constructed as to decrease in size from one of their ends to the other, the ends of one row being arranged to point between the ends of the openings in the succeeding row, the cut-away portions from the openings being bent upwardly from their connection with the plate at an angle thereto to its surface to provide inclined sheds serving to cover said openings.
In testimony whereof, I afix my signature in presence of two witnesses.
STEPHEN .T. KERRIGAN.
