DUST-LESS Asn-sIErEE.

To all whom it may concern:

Be it known that I, STANLEY SKIERMONT, a citizen of the United States, residing at Newark, in the county of Essex, State of New Jersey, have invented certain new and useful Improvements in Dustless Ash-Sifters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in ash sifters and particularly to hand operated ash sifters.

One object of the present invention is to provide a novel and simple device of this character whereby the sifting of the ashes can be accomplished without the dust flying on the operator.

Another object is to provide a novel and improved device of this character whereby the portion of the ashes not wanted can be easily and quickly dumped and the part wanted subsequently dumped without mixing them or interference one with the other.

Another object resides in the general simple and cheap formation of the device.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a side elevation of an ash sifter made in accordance with my invention.

Fig. 2 is a top plan view of the same.

Fig. 3 is a vertical longitudinal sectional view taken on the line 33 of Fig. 2.

Fig. 4 is a vertical transverse sectional view taken on the line 4-4 of Fig. 2.

Referring particularly to the accompanying drawing there is shown a metal box which includes the sides 10, the bottom 11, and the end 12, this latter member having its vertical marginal edge portions turned inwardly, a at 13, and soldered, or otherwise secured to the inner faces of the adjacent portions of the sidewalls 10. The other ends of the side walls are turned inwardly, as at 14: to form slideways for the reception of the removable end wall 15, which is adapted to he slipped vertically, as shown in the drawing. Secured within the box, at approximately midway of the height of the box, is the sifting screen 16, the sides being bound with the metal strips 17 the one at the open end of the box serving as a guideto retain the sliding wall 15 in proper position. The upper marginal edge portions of the side walls 10, as shown at 18, are bent to extend horizontally, and beneath these portions the removable top plate is arranged to be slipped. Secured to the upper face of the plate 19, and extending over the portions 18, is a strip 20, said strip being arranged near the inner end of the plate so -as to support the said end when the plate is in closed position. The other or outer end of the plate will be properly supported by the upper edge of the end wall 12. Handles 21 are secured to the outer faces of the side walls 10, which are adapted to be grasped by the hands of the operator to lift and shake the box.

It will be understood that the top plate is slipped into open position, and the ashes to be sifted dumped onto the screen, after which the cover is replaced and slipped into closed position and the box shaken. When the sifting ha been completed, the end wall 15 is moved upwardly until its loweredge is in line with the sifting screen. The box is then tilted so as to permit the refuse to be dumped from the portion of the box below the screen. When this has been done the wall 15 is removed entirely from the slideways and the part of the ashe to be retained dumped from the screen.

What is claimed is:

1. An ash sifter including a box having one end initially open through its extent, the vertical ends of the side walls of the box at said open end being inturned to form slideways, the upper portions of the side walls being inturned to form slideways, a sifting screen disposed within the box in a horizontal position, a dumping controlling door slidable in the first slideways and movable therein to carry its lower edge from one position below the screen to the other position above the screen, a cover plate slidable in the second slideways, and a trans verse strip secured to the cover plate and projecting over the inturned portions of the side walls to support the inner end of the said cover plate.

2. An ash sifter comprising a box having an initially open top and an end initially open throughout its extent, the box being otherwise without openings, a closure for the top movable into and out of active position, a screen disposed between the bottom and Specification of Letters Patent. 1 Patented Sept. 23, 19 19.

Application filed au ust 20, 1918. Serial No. 250,703.

the top and extending from side to side and end to end of the box in position to permit of dumping of cinders from it through the open end of the box and a closure for the intially open end of the box and movable to carry its lower edge from contact with the bottom to position interchangeably between the bottom and the screen and between the screen and the top closure, whereby ash below the screen and cinders above the screen may be separately discharged from the box Copies of this patent may be obtained for five cents each, by addressing Washington, I). 0.

without removal of the screen, the screen being disposed for contact of its corresponding end edge with the end closure when the latter is correspondingly positioned.

In testimony whereof I ailix my signature the presence of two witnesses.
