IMPROVBD ASH-SIPTER l The Schedule referred to in these Letters Patent and making part o! the same To all whom it may concern.-

Be it known that I, FRANCIS X. LIPP, of the city and county of Baltimore, inthe State ot' Maryland, haveinvented a new and useful Improvement in Ash- Sifters; and'I do hereby declare the following to be a full and correct description of 'the saine, suthcient to enable others skilled in the class to which my invention-appertains to fully understand and construct.- the saine, referenceV being had to the accompanying. drawings which make part of this specification, and in which-f- Figure 1` is a longitudinal vertical section of` my improved ash-sitteuin line z, z, fig. 2;

Figure 2 is a cross-section ot' the same in line x x, fig.1;and r Figure 3 is a 'sectional inside view of the sifting-v drnm in line y y, iig. 1.

i Like letters of reference indicate like parts in the several figures. r

The nature of my invention consists- First, in forming one of the pivots ot' the revolving drum by a pipe through which the ashes to be sii'ted are conducted into the drum; i

Further, in the peculiar construction of the pivots, and in the arrangement ofa slidiugidoor to regulate or entirely shut oit' the influx of ashes and cinders; and

Lastly, in the construction and arrangement of a reversible trough for the purpose of conducting the silted cinders from the drum to either side. v

A, in the drawings, represents the standards between which the drum B is hung. g

This drum consists ot' two octngonal end boards, C D, connected to each other by wires e, which are covered with wire orother suitable gauze, the meshes of which are wide enough to allow ashes to pass outv freely, but not so large-as to let the cinders pass, which in sifting are retained in the drum.

One ofthe eight sides of the drum is arranged as a door, as shown at b, tig. 3, so that, after sitting, the

, cinders may be removed through it from the drum.

The end board C has a shorttrnnnion, c, revolving in a suitable hearing'on one standard, A, and provided `at its outer end with a crank, j', by Ineans ot' which the drum is revolved. y

The other end board D has a central opening, al, corrcspom'liug with the opening of a` tube, E, which is provided with a disk, g.

On the outside ot' board D is secured arim,1 formed in two pieces, and with a central concentric an'ge, h, forming a narrow'circular recess iu which the disk g is placed. This disk is thus made the' pivot around which that end of' the drum revolves, the ange h moving around the disk as the drinn is turned.

The tube E Vextends in au upwardly-inclined position from the drum, and at its upper end is provided with a hopper, G, into which the ashes to be sifted are poured and pass through the tube Vinto the drum.

On the inside of the end board D, one on each 'side of the opening (Z, are two ways, t, in which a door, H, slides, which covers the opening d, andis provided with a rod, j, ending on the outside of the drinn in a handle, `k, by means of which it is operated.

Each standard A has a cross-piece, a, situated below the drum, which cross-pieces are connectedto each other by a rod orwire, I, placed centrally'uuder lthe drum.

This wire forms the pivot for a reversible dischargetrough, J, divided in the center by a. board, l, into ,two chutes. This trough is n'ot secured to the wire, but merely rests on it, the wire passing into a .central groove, 'as shown in tig. 2, to prevent the trough from slipping off from the wire.

Ashes are'poured into the hopper-KG, and pass (the door H. being slid open) through the tube Eand opening d into the' drum B. The door H is'then closed, and the door b of the drum secured, when, by turning the crank f, the drum is rapidly revolved. The ashes strike against the wires e, and the finer particles pass through the gauze, while the cinders are retained in the drum. When the ashes have beensuliiciently sii'ted, the door b is-opened andthe cindersare allowed to fall ontr ot' the drum into the trough to either side, as the trough may be placed.

llaving thus described my invention, g

What I claim as new, and desire to secure by Letters Patent, is'- 1. The rim F, with its iiange h formed in two pieces, secured on the end board D, and rotating around the disk g of the feed-tube E, substantially as andfor the purposes described.

2. 'lhe feed-pipe E, when provided with a disk, g, which forms the pivot for one end of the drum of a sitter, substantially as and for the purposes described.

3. A sifter in which the feed-pipe forms one of the pivots of the revolving drum, for the' purpose'of continual feeding, substantially as herein described.

4. In a sitter, in `combination with'the above parts, a reversible disciiarge-trongh, J, operating and arranged snbstantiallyas and furthe purpose herein set forth.

VVitnesses: FRANCIS X. LIPP.
