UNITED STATES PATENT OFFICE.
DAVID J. MIDDLETON, OF KINGSTON, ROBERT M. KEEPER, OF EDWARDSVILLE, AND JOHN F. BALLAMY, OF LARKSVILLE, PENNSYLVANIA.
COAL-SEPARATOR.
To all whom it may concern:
Be it known that we, DAVID J. MIDDLETON, ROBERT M. Kenrnn, and JOHN F. BALLAMY, citizens of the United States, residing at Kingston, Edwardsville, and Larksville, in the county of Luzerne, State of Pennsylvania, have invented a new and useful Coal- Separator, of which the following is a specification.
This invention relates to improvements in coal separators.
The primary object of the present invention is to so construct a spiral separator as to prevent excessive breakage of the coal.
A further object of the invention is to provide means for adjusting the slate chute whereby the angle at which the same is disposed may be changed to allow for irregularities in the slate.
In the drawings :Figure 1 is a side elevation of the separator. Fig.2 is a section taken. through the coal and slate chutes. Fig. 3 is a perspective view of one of the supports for the chutes. Fig. 4 is a detail view of the screw for adjusting the slate chute. Fig.5 is a perspective view of one of the brackets which are secured to the under face of the slate chute. Fig. 6 is a detail view showing the manner in which one of the coal sections may be removed and a delivery chute secured in position. Fig. 7 is a perspective View of the chute shown in Fig. 6. Fig. 8 is a perspective view of one of the sections of which the slate chute is formed. Fig. 9 is a perspective view of one of the sections from which the coal chutes are formed.
In the drawings, 10 designates the chutes which are three in number and which are supported in the usual manner by a centrally disposed support 11. The chutes are formed in sections 11 and 12, the sections 12 forming the inner or slate chute and the sections 11' forming the outer coal chutes. The separators of this general type are constructed in a manner which allows the coal to fall a considerable distance from the slate chute which causes considerable breakage due to the fact that the coal falls over the slate chute to the coal chute which is disposed below the same. As the material is fed to the separators the coal which is irregular falls over into the coal chute and the slate which is flat slides in the slate chute, having a tendency to slide toward the post.
Specification of Letters Patent.
Application filed September 28, 1911.
Patented Oct. 8, 1912.
Serial No. 651,839. a
To avoid this breakage of the coal the chute sections 11 and 12 are disposed side by side, the coal rolling over into the coal chute and descending in almost the same spiral line with the slate, the contact of the coal with the chute being so slight as to avoid breaking the same. The slate which is ordinarily flat slides in the inner chute but at times this slate is irregular and has a tendency to roll out of the slate chute and into the coal chute, riding up the incline in the same manner as the coal. To prevent the irregular slate from falling over into the coal chute the slate chute is so constructed that the angle at which the same is disposed may be varied. The sections 12 which form the slate chute are formed with downwardly disposed flanges 141 which overlap the upwardly disposed flanges 15 of the sections 11, which form the coal chute, the flanges being disposed at such an angle as to permit the chute to lie at an angle to the support 11. The sections are supported by the rods or brackets 17 these rods being secured to the support, the rods being given a compound right angle bend at a point near their centers, the portion 18 supporting the slate chute and the portion 19 the coal chute. The chutes thus being held in slightly different planes. Arranged on each of the rods is a plate or bracket 20 which is formed with an aperture 21 through which a screw 22 is adapted to extend. A bracket 24; is arranged on the under face of each of the sections 12 and the screw 22 is adapted to pass through an opening 25 in said brackets, the same being advanced and retracted to raise or lower the section 12, a nut 26 being arranged on the screw, the same contacting with the bracket 25 preventing the displacement of the screw. The sections 12 are secured to the rods 17 at the point 30, thus as the screw is advanced or retracted the flange 15 will slide on the flange 14, thus changing the angle of the slate chute.
In this construction it will be noted that the slate chute may be readily adjusted to retain slate which is irregular, each of the sections being independently adjustable.
Should it be desired to remove the coal before the same reaches the delivery ends of the chute a delivery chute 28 maybe secured at any point along the coal conveyer one of the sections 11 being removed in order that the delivery chute may be secured to the.
edges of the adjacent sections, the chute 28 being formed with an oii set portion 29 to hold the same in position.
What is claimed is 1. A coal separator consisting of a plurality of spirally arranged coal and slate chutes disposed in an inner and outer series, the coal chutes being arranged adjacent the outer edge of the slate chutes, said slate chutes being formed with downwardly eX- tending flanges, said coal chutes'being provided with upwardly extending flanges, a supporting post, supporting rods bent intermediate their ends and secured to said as our own, we have hereto afiixed our signa- I post, the inner and outer portions of said rods lying in diflerent planes, and means supported by sald rods for ralsmg the outer edge of the slate chute.
2. A coal separator consisting of a plurality of spirallyarranged coal and slate &
chutes disposed in an inner and outer series,
the coal chutes being arranged adjacent the w outer edge of the slate chute, said slate chutes being formed with downwardly extending flanges, said coal chute being formed with upwardly extending flanges, a supporting post, supporting rods bent intermediate vtheir ends and secured to said post, the inner and outer portions of said rods lying in different planes, the slate chute being secured to said rods, a bracket supported by said chute, an apertured plate supported by said rods, and an adjusting screw passing through said plate and bracket to raise the flanged edge of said slate chute.
In testimony that we claim the foregoing tures in the presence of two witnesses.
