JULIUS L. BARROXVS, OF PORT HURON, MICHIGAN.

ASH SIFTER.

SPECIFICATION forming part of Letters Patent No. 366,065, dated July 5, 1887.

Application filed July 15, 1886. Serial No. 208,082. (No model.)

To aZZ whom it m cry concern.- Be it known that I, JULIUs L. BitRnows, of Port Huron, in the county of St. Clair and State of Michigan, have invented new and useful Improvements in Ash-Sifters; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings,which form a part of this specification.

This invention relates to certain new and useful improvements in the construction of ash-siftcrs; and the invention consists in'the peculiar construction and combination of the various parts, all as more fully hereinafter set forth and claimed.

Figure lis a perspective view of my improved ash-sifter,and Fig. 2 is a central vertical longitudinal section of the same.

In the accompanying drawings, which form a part of this specification, A represents acir- .cnlar base provided with a downwardly'pio jecting flange, a, and which is designed to set over a barrel or other suitable receptacle for ashes. Mounted upon this base A is a case, 13, upon which is surmounted the hopper C, said hopper being provided with asuitable cover, D. i

E is a screen-frame hung within the case B by the hangers F in such a manner that said sieve can be reciprocatcd by means of the hand-lever G, which projects through the side wall of the case B, the inner end of such lever being pivotally secured to a cross-girt, b, of the screen frame. The top of this screen-frame is partially closed by a plate, H, which also partially closes the discharge from the hopper, as shown, so as to prevent the entire eontents of the hopper when the sifter is operated the case B and is turned upwardly, so as to project above the inner end of the screenframe, as shown.

11 z" are rods, one secured to the inner side of the case B and the other to the cross-cleat b. The other ends of these rods engage theknocker I and prevent its falling too far.

In practice, the device being constructed substantially as described, thematerial to be sifted is emptied into the hopper, the'greater portion of it lying upon the top plate of the screen-frame. The cover D is then closed and the lever so operated as to reciprocate the screen-frame, thus effectually and thoroughly separating the ashes and small particles from the cinders and coal, the ashes falling through into the barrel or receptacle beneath,while the coal and cinders pass over the sieve and into a bag or other receptacle which may be placed at the discharge end of the sieve.

In the reciprocation of the screen-frame the inner end of such frame strikes foreibl y against the upturned end of theknocker I,eausing the longer and free end of such knoeker to fly up and forciblystrike the under face ofthe screen, and thereby loosen any cinders or coal that may have become lodged therein.

What I claim as my invention is The combination, with the case, B, crossgirt 1), screen E, and lever G, pivotal] y secu red to said girt, of the knocker I, pivoted to said case and having a long and a short arm, the

former extending beneath and parallel withsaid screen and the latter arranged in the path of said screen, and the rods 73 i, all substantially as shown and described, and for the purpose specified.

JULIUS L. BARROWS.
