I Letters Patent No. 83,653, dated November 3, 1868.

The Schedule referred to in these Letters Patent and making part of the same.

To all wlw/mit 'ma/y concern:

Be it known that I, HENRY A. NEWHALL, of Proviand State of Rhode Island, have invented a new and improved Method of Sifting Dirt and Ashes om Coal and other Substances. The following is a' full and' exact description of the same.l f

The nature of n'ly invention consists in making use of a current 'of'.` air, by means of the draught of a chimney-flue, through a sifting-apparatus, during' the process of sifting, screening,

narily iiies' out into the room, is carried cti' into a stove or chimney. To enable others skilled in the invention, I will and operation.

Figure l. a a, c represent an ordinary chimney, with an opening in the side, for the fimnel d d, at q. C repart to understandmy proceed to describe its construction resents an ash-box, of any convenient form and sub,

stance, which/is open at the top, and so constructed, with a narrow. rimorcleat around it at the top, as to allow the sifting-box, on three sides, to t within the cleat, or the same may be otherwise securelyfastened tothe sifting-box. a: :z: a: represent a bottomless siftingbox, so constructed as to it on to the ash-box, and

-within a cleat around' three sides of the same, but projecting over it at the end, y. Across the sifting-box, at the bottom ofthe screen, and at the edge of the ash-box, is a bar, o o, on which the screen rests. W represents a hook and staple, for the purpose of hold- .ing the ash-box'and sifting-box securely together. e ,e e represent a screen, composed of wireor other maf connecting the sifting-apparatus with the chimney; by which it willbe seen that, while the screening-process is going on, there will be a constant currentor draught of air through the sifting-box om the open aperturesv therein, by means of which all the dust, ordinarily arising from the. sifting-process, will be carried into the chimgey, andprevented from flying out into the room.

Figure 2. a a a represent the chimney, as in g.1.; d, the funnel, which enters the chimney at q; c, the

ash-box or barrel; e e, the screen'; f j, the pan, intoV which the coal, and other substances are placed for sifting; h, the handle of the screen or sieve, which operates horizontally; g g g g, the cover; from which it may be seen that, while the'process of sifting is going on, there is a constant current or draught of air fromunder. the cover lg ggg, and. through the same,

and through the funnel d,', at n, which eiectually prevents the dust from flying out into the room. .f "Figure 3 represents -the same process asg. 1,. but

or otherwise moving coal and other substances,whereby'the dust, which ordii using the draught through a stove, fm, into the chim ney,'and combining the ash-box and sifting-box in one. d represents -the funnel; t e e e, theA screen; h and k, oriices, through which the coal and other substances are poured upon the screen. The asheswill fall throughthrough an aperture at y, and drop into the hod s. R represents a spout, through which the ashes maybe at its upper end, the ashes may be discharged at the aperture y, passing under the end of the screen-at e e.-

Fignre Lirepresents an ash-hod, #about a foot square on the bottom, and about fifteen inches in height, with au aperture in the upper corner of the back side of the same, about four inches square, into which is .fastcned, the dust-pipe or funnel, w, extending out about three inches.- Through this` pipe w, the ashes may also be emptied from the hod. a represents a door, extending across the front of the hod, about four inches in width. l

drawn over the upper part of the same, and turning down at o-about an inch. 'lo use thev two (igs, 4 and 6) in connection, insert the funnel w into the door of hook or catch. Take the shovel sifter', described in same into the hod t at the opening in the front, turn it bottom side up, and slide the shovel sifter rapidly on its handle, from right J,to left, on the edge of the doorway s by which lit will be seen that the ashes will fall into the bottom of the hod t, the dust will be carried o", by the draught through the hod, into the stove and liuc, and the coal left in the sitter-shovel, to be placed in the stove again, Or into a separate hod.

Figure 7 represents the same operation by the attachment of the sifting-hed to an ordinary cook-stove, with the addition of a bottomless drawer o r extension-pipe, v, having 'the under side open, andone end closed, represented in Figure 5, which is to be inserted in the pipe w, forthe purpose of making the connection of the draught through the hod t into the cook-stove, through the pot-holes o n the top' of the stove. TrIhe like result as before described wil1-be attained.V

4I am aware that an inclined screen; as described in figs. 1 and 3, is not new, and, therefore, I do not claim it. I am also aware that a horizontal screen or sieve, similar to that described in g. 2, has beenbefore used, and I do not claim this; but

What I do claim .as novel and useful, is

1. A funnel, to connect the enclosing-case of a coalsifting apparatus with a iiue, constructed substantially in the manner herein described. f

2. The sifting-box t, provided with pipes fw v, constructed in the manner and for the purpose herein set forth. v HENRY A. NEWHALL.
