JOSEPH BULLOOK, OF COHOES, NEW YORK.
4COAL AND ASH SIFTER.
SPECIFICATION forming part of Letters Patent No. 249,582, dated November 15, 1881.
Application tiled September 24, i881. (No model.) l
To all 'whom it may concern:
Be it known that I, JosErH BULLocK, of the city of Oohoes, in the county of Albany and State of New York, have invented a new and Improved Goal and Ash Sitter, ot' which the following is a specification.
Figure l is a vertical section oi' my device on the line z z, Fig. 2, and designed to show the relative position ofthe inclined sieve, chute, and chambers underneath the sievesl` Fig. 2 is a similar view on thevline y y, Fig. l.
The object of my invention is, by the combination and arrangement of two or more iixed inclined sieves, inclosed as setl forth, in operation by gravity acting on the particles,to separate and clean coal and ashes, &c and to conduct the same into their respective drawers. This I accomplish by the inclined sieves placed relatively to each other as indicated, and by inclosing them in casing and chute, as hereinafter described.
The casing I is made of wood or other material, with cover K, drop-door A,snpported by the receding catch j, and such'door has metallic springs or spirals b, adjusted at or near the hinge O, intended to force back the drop-door toits closed condition when released of its load. At the bottom ot' the narrower part of the casing are extended shoulders l', which are provided to cover and guide the drawers G and H.
The bottom chamber lof the sil'ter is divided into two divisions by the partition-plate O, which plate extends across the chamber, leaving aspace which isfdled up by the entrance therein ofthe chute F, as seen in Fig. l. The bottom of the chute is a metallic sieve of the same width as the chute, extending diagonally across the vertical chamber, and at an angle of about forty-tive degrees with the side ot the casing. i
Adjusted transversely to the upper en d of the chute is the metallic sieve D, which rests at about an angle of forty-five degrees with the vertical side of the casing, leaving a space above for the swing of the drop-door A, which t isz`hinged to the side of the casing, and this door is re-enforced and forced backward into its first position, when released of its load of` coal, by the metallic spirals b, adjusted at or near the hinge O.
The'catch j holds the door in position for the load, or when a continuous iiow ot" the maa sieve D is soldered into position, as seen at n, or the same is inserted in a suitable groove, if sieves of different apertures are desired, through a swingfdoor made in the casing.
As will be seen in the figures, and as indicated bythe arrows, the liner particles, in their descent, pass into the drawer H,as shown by the arrows '0, while the coarser particles gravitate down over the first and second sieve,
through the chute F, into the drawer G, as
shown by the arrows a'.
To facilitate the passage of the ashes or finer particles between the angle formed by the chute and side of the case, I form a wedge-shaped protu'berance at P, Fig. l, to guide the particles through passages mat the side of the chute, as seen in Fig. 2.
In operating my device Aadditional sieves, placed relatively to `each other asindioated, may be used, wl1ile, it' the drop-door is left open, coal or other material admitted in a con.- tinuous iiow will gravitate downward and be eifectually screened, and the coarser and finer particles separated into their respective chambers.
'My device may also be useful and adapted to the screening of gravel and sand from a 'bank from which the material in continuons Iiow is allowedto gravitate downward over the inclined sieves and the particles separated into their respective chambers, as indicated.
As will be seen in the drawings and aecompan yin g specification, the process of screening and separating the coarser and finer particles requires no motive power or artificial movement otthe sieves, as in the'use of the ordinary sieves.
What I claim, and desire to secure by Letters Patent, is-
An improved coal and ash sifter with the following elements in combination with the casing, viz: a drop-door, A, held in position by catch 7' and supporting-spirals b, two or more inclined sieves, adjusted as shown, the latter inclosed in a chute which rests on partitionplate O, with coal and ash drawers, all arranged substantially as described, and for the purpose set forth.
