ITED STATES ATENT FFICE.

SETH WHEELER, OF ALBANY, NEW YORK.

ASH-SIFTER.

Specification of Letters Patent No.30,942, dated December 18, 1860.

To all whom it may concern:

Be it known that I, SETH VHEELER, of Albany, in the county of Albany and State of New York, have invented a new and useful Improvements in Ash-Sitters, the simplicity of construction and operation of which will be clearly set forth in the following specification.

The nature of my improvement consists in the use of a reciprocating corrugated sieve, inclosed in a suitable case or box, and placed in a diagonal position, said sieve being hung on pivots or journals, and agitated by means of a lever or crank, rod and treadle, by working on the outside of said case or box.

A scuttle provided with a pivot or journal on one side, and a square stud on the other, is suspended in the case or box, the round journal Working in a slot formed in one side, and a square stud resting in a` socket which has a round shoulder, passes through the other side of said case or box and is provided with a handle or lever on the outside. A cover tits closely over the top to prevent the dust from escaping while the machine is in operation, and two compartments or drawers are placed in the lower part and are divided by a detlecting partition which extends up near the lower edge of the corrugated sieve, by means of which the sifted coal and cinders falls into one of the drawers and the ashes and dust into the other.

The operation of the machine is as Jfollows: The cover of the case or box being removed the scuttle is taken out, illed and replaced within, resting on the slot out in one side and the square socket in the other. The cover is then put on and the handle secured to the square socket is turned, thereby dumping the scuttle and discharging the contents on the diagonal corrugated sieve, which is set in motion by a lever secured to its axis which is also connected to a treadle operated by the foot, by depressing which the corrugated sieve is raised, and when thepressure iis removed, a spiral spring connected to the rod and side of the case or box, draws it back to its original position, thereby agitating the sieve and sifting the coal and ashes thoroughly.

Having thus set forth the nature" of my improvement and to enable others skilled in the art to make and usethe same, I will now proceed to describe it and certify that the accompanying drawings are a full and correct represeptation of the same like letters corresponding with like parts.

Figure 1 represents a longitudinal section of the ash sifter; Fig. 2, a perspective View of the same with one side broken away to show the interior; Fig. 3, a side elevation of the same; Fig. 4L, a transverse section of a part of the machine showing the scuttle and manner of dumping.

A, Figs. 1, 2, 3, t, is the case or box, B the diagonal corrugated sieve provided with bearings, b, Z), to one of which is secured the lever C connected to the rod D passing through a spiral spring E one end being secured to it and the other end being fixed to the case or box A.

F is a treadle secured to the lower end of the rod D which is kept in position by the guide G.

H is a scuttle suspended on the stud and square socket I (Fig. l).

J is the handle fixed to it for dumping the scuttle H.

K is a plate which covers the space between the upper end of sieve and side of box or case A and is secured to it for the purpose of preventing the ashes from falling through without sifting.

L is the cover of case or box A, M the delecting plate or partition, N the drawer for the sifted coal, O the drawer for the ashes and dust.

'Ihe scuttle H when lled is placed in the box A setting in the slot and the socket I (represented at Fig. 4). The handle J is then turned which dumps the scuttle H (as represented at Fig. 2) and discharges the contents on the plate K from which it falls to the corrugated sieve B, which is then set in motion by means of the treadle F operating rod Dand lever C. When the treadle F is depressed the sieve B is in the position indicated by dotted lines (Fig. l) and when the foot is removed the spring E draws it back to the original position, the coal and cinders fall into drawer N and the ashes and dust into dra-wer O.

I claim- The use of lever C, treadle F and spring E when used in combination with the sieve JIdsubstantially and for the purpose speci- SETH WHEELER.
