Other objects of theinvention will appear from the following detailed description.

The invention consists generally in various constructions and combinations, all as here inafter described, and particularly pointed out in the claim.

In the accompanying drawings, forming part of this specification, Figure 1 is a verti cal section of an ash-sifter box and cylinder embodying my invention. Fig. 2 is a perspective of the cylinder removed from the box. Fig. 3 is a perspective of the cylinder with the cover removed. Fig. 4 is a perspective of the cover, and Fig. 5 is a detail section of one of the locking devices for securing the cover of the cylinder to the main portion thereof.

In the drawings, 2' represents a box, rectangular in form, having a removable top portion 3, that forms a tight joint with the upper edges of the box and prevents the escape of dust from the ashes during the operation of sifting. The upper portion of the box is readily removable when itis desired to fill the cylinder or em ptyit and the box. The sifting-cylinder which I prefer toprovide is divided longitudinally atone side of its center into two sections, thelarger section forming areceptacle wherein the ashes to be sifted are deposited and the other section forming a cover to close the opening in the larger section during the operation of sifting. The

larger receptacle or section comprises heads 4, preferably of wood, connected at intervals by bars 5, which, with said heads, form a skeleton frame for the wire-screen covering 6. The edges of this screen at the ends of the cylinder are covered and protected by hoop-like bands 7, secured by any suitable squared end 9,'that extends through the wall of the box on one side and is provided with an operating-crank 10. The smaller cylindersection, forming'the cover for the cylinder, comprises segment-like heads 11, connected by a wire-screen covering 12, that is inclosed by a metallic frame consisting of curved bands 13, secured to the curved peripheral edges'of the heads-ll and connected at their ends by straps 14, that depend below the heads 11 and are adapted to lap down over the sides of the ash-receptacle and form a comparatively tight joint therewith. I also prefer to provide flanges 15 on the inner'surfaces of the heads 11, that depend within the ash-receptacle and cover the joints between the heads 4 and 11 when the sections are placed together. Any suitable means may be provided for securing the sections of the cylinder together; but I prefer to provide a fastening device at each end of the cylinder consisting of a casing 16, secured on each head land having an inwardly-ex,

tending lug 17, that'is adapt-ed to engage the cam-leverisurface 18, provided on a plate 19 Within a casing 20. The casing 20 is secured to the head 11 at each end of the smaller section of the cylinder, and an operating-lever 21 permits the person using the device to swing the plate 19 on its pivot and move the cam-surface 18 into engagement with the lug 17 or out of engagement'therewith. This camleverdevice has a drawing action when the parts are brought together and tends to draw the two sections of the cylinder into close contactwith each other and insure a comparatively tight joint between them and prevent any possibility of theirbecoming separated during the operation of sifting. As soon as the contents of the cylinder have been thoroughly sifted, the. operator by manipulating the lovers 21 can easily disengage the sections and remove the smaller one. The larger section can then be readily detached from its support and emptied of its contents, refilled, and the sifting operation repeated. l I have found it of great advantage to hav the cover portion of the cylinder entirely removab1e,as the ash-receptacle can be emptied much more readily than where a hinged cover is employed that is always in the Way and is frequently twisted or torn from its hinges when the cylinder is being emptied.

I claim as my invention- In an ash-sitter, a cylinder comprising two separable sections or members formed by dividing the cylinder longitudinally on one side of its center, each section comprising two heads, and a wirenetting connecting the same, the smaller section acting as a cover for the opening in the larger section, flanges provided on said smaller section to lap down past the edges of the opening in said larger section and form a comparatively close joint therewith, and cam-lever devices provided on the heads of said sections and arranged to draw up their contacting edges and lock them snugly together.

In witness whereof I have hereunto set my hand this 25th day of June, 1903.
