ASH-SIF'IER.

Specification of Letters Patent.

Patented May 15, 1917.

Application filed November 11, 1916. Serial No. 130,752.

To all whom it may concern:

Be it known that I, SAMUEL DUSKES, a subject of the King of Great Britain, residing at Montreal, in the Province of Quebec,

5 Dominion of Canada, have invented new and useful Improvements in Ash-Sifters, of which the following is a specification.

The invention to be hereinafter described relates to ash sifters.

In order to more clearly disclose the construction, operation, and use of the invention reference should be had to the accompanying drawing forming part of the present application. Throughout the several views of the drawings like reference characters designate the same parts.

In the drawings Figure l is a vertical cross section;

Fig. 2 is a horizontal cross section; and

Fig. 3' is a detailed view of one of the sifter engaging bars, in cross section.

The main objects of the invention are to provide a simple, compact, eflicient, durable, and economical, dustless ash sifter which may be made in large quantities at a comparatively low cost.

One important point in the present invention is that the regular standard ash can and regular standard circular ash sifter may be used, without change or alteration.

Referring to the drawings in detail, 1 indicates a regular standard ash can, and 2 a regular standard circular ash sifter. EX- tending diametrically through the can body, and a short distance below the top is a revoluble shaft 3 to which is removably connected a crank handle 4.

A cotter pin or like securing device is passed through the opposite end to prevent the shaft from slipping through. Secured to this shaft, near its opposite ends, are two short bars 5, so positioned as to engage an extension rim 5 of the vertical wall of the sifter when the shaft 3 is revolved. These two bars are so arranged on the shaft 3 that they extend at right angles to each other. Thus, while one end of one bar is engaging and lifting one side of the sifter, the end of the other bar is just dropping down and allowing that side of the sifter to fall. Each bar 3 is provided with washers 3 which prevent the bars from slipping from rim 5' onto the screen of the sifter. At points midway between the ends of shaft 3 and diametrically opposite each other, are two L plates or brackets 6. These are secured to the inside wall of the ash can, at the height of the shaft 3. These plates engage the edge of the ash sifter and prevent it from tipping down on either side of the shaft 3. Consequently, as the shaft 8 is rotated, the bars 5 cause the sifter to rock up and down, at opposite sides. During this rocking motion, the L plates take the place of pivotal points across which the sifter rocks. As the bars 5 rotate upwardly and then downwardly in engagement with the rim 5 they will also cause the sifter to travel partway with them, in a horizontal direction. Thus, the sifter will have both a rotating movement in a horizontal plane and a rocking movement in a vertical plane. These two movements combine into a perfect sifting movement.

To lessen the jar of engagement between the ends of the bars and the sifter edge, the bars are overturned as at 7, to give a slight spring.

In sifting, the usual cover is fitted on to the can before sifting is started. The sifting operation then becomes dustless.

It is thought that the operation and use of the invention will be clear from the preceding detailed description.

Changes may be made in the construction, arrangement, and disposition of the several parts of the invention without in any way departing from the field and scope of the same, and it is meant to include all such in this application.

Having described my invention, what I claim as new and desire to protect by Letters Patent is:

1. An ash sifter of the character described comprising, an ash can, a shaft journaled therein, bars carried by said shaft and arranged at right angles to each other, and a sifter adapted to be engaged by said bars.

2. An ash sifter of the character described comprising, an ash can, a shaft journalecl therein, bars carried by said shaft and arranged at right angles to each other, a sifter adapted to be engaged by said bars, and means carried by said bars and adapted to prevent said bars from engaging the screen portion of said sifter.

3. An ash sifter of the character described comprising, an ash can, a shaft journaled therein, bars carried by said shaft and arranged at right angles to each other, a sifter provided with an extension rim adapted to be engaged by said bars, and means carried be engaged by said bars, and Washers carried by the opposite ends of each bar and adapted to engage said extension rim to prevent lateral movement of said sitter relatively to said bars.

Signed at Montreal, Province of Quebec, Canada, this 8th day of November, 1916.

SAMUEL DUSKES.

by said bars and adapted to engage said extension rim to prevent lateral movement of said sitter relatively to said bars.

4. An ash sifter of the character described 5 comprising, an ash can, a shaft journaled therein, bars carried by said shaft and arranged at right angles to each other, a sitter provided With an extension rim adapted to Copies of this patent may be obtained. for five cents each, by addressing the Commissioner of Patents, Washington, D.
