JOHN GRAVES, OF GREEN POINT, ASSIGNOR TO HERMAN MILLER, OF NEW YORK, N. Y.

ASH-SIKFTETR.

SPECIFICATION forming part of Letters Patent No. 254,638, dated March '7, 1882.

Application filed July 23, 1881.

To all whom it may concern Be it known that I,JoHN GRAVEs,of Green Point, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Ash Receivers and Sifters, of which the following is a specification.

My invention relates to ash-receivers which have arranged within them sifters or sieves into which the ashes and cinders are placed, and which are so supported that they may be partially rotated or shaken to sift the ashes through them.

The invention consists in the combination of a receiver having an imperforate cover, a sifter or sieve supported therein and adapted to be turned or partially rotated, open loops or sockets which project inward from the upper edge of the sifter or sieve and serve as handles whereby it may be lifted, and lugs projecting downward from the under side of the cover and engaging with said loops or sockets, whereby provision is afforded for rotating or turning the sifter or sieve by rotating or turning said cover.

In the accompanying drawings, Figure 1 represents a central vertical section of a receiver and sifter embodying my invention. Fig. 2 represents a planthereof with the cover removed, and Fig. 3 represents an inverted plan of the cover.

Similar letters of reference designate corresponding parts in all the figures.

A designates the receiver, which may consist of a strong sheet-metal can, and which in this example of my invention is strengthened by a re-enforcing band, A, at the top. The receiver is provided with handles a, whereby it may be lifted.

B designates animperforate cover, likewise made of sheet metal, and provided with a downwardly-projecting rim, b, which fits inside the band A, and with handles B, which are shown as upon opposite sides of the center, and serve to lift the cover or to partly rotate or turn it upon the receiver A.

C designates the sifter or sieve, which is composed of a sheet-metal cylinder having a (No model.)

O has a flange, d, overlapping and resting upon said shoulder.

In lieu of having a continuous shoulder and a continuous flange, either the receiver or the sifter might have a continuous flange, and the other having projecting lugs overlapping the same.

The flange d turns freely on the shoulder c, and permits of the sifter or sieve being partly rotated or turned to shake the ashes through the bottom 0.

The arrangement of the flange d at the top or upper edge of the sifter is advantageous, as all ashes which lodge upon the shoulder 0 can then be brushed into the sifter, and there is no danger of ashes and cinders gettingbetween the sifter and receiver and interfering with the rotation, of the sifter, as there would be if the flange d and shoulder a were at or near the bottom of the sifter.

Upon the sifter or sieve C are inwardlyprojecting sockets or loops 1) and E represents lugs or projecting tongues upon the under side of the cover B, which enter'the sockets or. loops, as clearly seen in Fig. 1, thus locking the cover and sifter or sieve together, so that the turning'of one is transmitted to the other. By this means the sifter or sieve C may be very easily rotated or shaken circumferentially while the cover B is on, closing the receiver tightly and preventing the escape of ashes and dust.

The sockets or loops D form handles whereby the sifter or sieve may be conveniently lifted and removed from the receiver.

It will be observed that after the ashes are placed in the sifter it may be operated by taking, hold of the handles Bof the cover, and there is no possibility of dust and ashes escaping, as there would be if there were holes in the cover.

I am aware that an ash receiver and sifter has been made in which the sifter or sieve has attached to it rods which project upward ets D, projecting inward from the said sifter or through holes in the cover, and serve as hansieve and forming convenient handles wheredles for partly rotating or turning the sifter by it may be lifted, and the lugsE, projecting or sieve, and I therefore do not claim this as downward from the under side of said cover 5 my invention. and engaging with said loops or sockets, all

What'I claim as myinvention, and desire to substantially as herein specified. secure by Letters Patent, is- JOHN GRAVES.
