To all whom it mag concern."

Be it known that I, ALBnnrRrrsnMA, a citizen of-the United States, residing at Vichert, in the county of Kankakee, State of Illinois, have invented certain new and useful Improvements in Coal-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 is appertams to make and use the The present invention relates to new and useful improvements in sifting devices, more particularly of that type intended for sifting ashes.

t is the object of the present invention to provide a device of maximum simplicity wherein the dust incidental to the sifting op eration is confined to afford a comparatively comfortable and clean sifting operation, this simplification of structure being procura ble by the provision of a dust confining means carried by and reciprocable with the sieve.

It is further an object to provide an arrangement wherein a sieve may be associated with or detached from a dust confining means of the present nature in a most ready manner to facilitate loading and unloading of the sieve between the sifting operations.

A still further object resides in the pro vision of an arrangement for dampening the dust and ashes discharged from the sieve in the sifting operation.

lVith the above and other objects and advantages in view, the invention resides more particularly in the novel combination, formation, and arrangementof parts hereinafter described and particularly pointed out in the appended claim.

In the accompanying drawings:

Figure l is a perspective view of a sifting device constructed in accord. nce with the present invention.

Fig. 9, is a vertical sectional view therethrough on the line 2-2 of Fig. 1.

Fig. 3 the cover removed.

Fig. 4 is a sectional .view taken nally through the device.

Flg. 5 is a detail perspective view of one of the water distributing apertures and the shield therefor.

Referring now more particularly to the aceompanving drawings, there is provideda longitudiajn iniperforate' e der. wait frame 5 V 9, bottom 10 and a within the casing is a plan view ofthe device with shape and carrying a screen bottom 6, a handle 7 projecting outwardly from the central portion of one end of the frame. This frame is adapted to fit within the upper portion of a casing constructed of relatively light metal and con'iprising side walls 8, end walls cover 11 secured by hinges 12 at one side edge to an edge of the upper edge ofja wall 8. The walls of the casing are provided with inwardly projecting seating blocks 15 at the corners of the casing adapted to support the sieve frame substantially flush with the top of the casing, and the handle 7 of the sieve projects through a slot 16 in the upper portion of one end wall 9 which slot is open at the upper edge of the wall.

Thus the sieve may be readily secured or removed therefrom, and in secured relation it is noted that the sieve and casing are held against any relative movement and thus the casing may be shaken or reciprocated with the sieve in the usual manner by an operator gripping the sieve handle 7. A maximum freedom of shaking action for the sieve is thus afforded and a maximum simplicity of structure is attained in the provision of a means for confining the dust of the sifting operation, while the casing by reason of its light nature does not interfere materially with or add to the labor of sifting.

In the present structure an ash pan 17 is slidable in the bottom of the casing, and is removable through an opening 18 in the end wall 9 through which the sieve handle 7 prO ectS, this pan being normally secured within the casing by a clip plate 19 pivoted on the outer face of the wall 9 and engageable with its outer wall. Thus. the casing may be emptied of'ashes without the necessity of tilting the same. For sprinkling the ashes as they are shaken from the sifter and thus lessening the amount of dust within the casing, a pair of elongated cylindrical water reservoirs 20 are secured to the inner face of the side casing walls 8 in the space between the bottom of the sifter and the top of the ash pan by suitable strips 21 embracing said cylinders and riveted to the casing walls. These cylinders are provided with filllllf nipples 22 at their central porspace by the jarring incident to the sifting operation. Cupped shield plates 24: are secured to the reservoirs immediately above these openings and serve to prevent clogging of said openings by ashes dropped from the sieve, and also assist in spreading the Water as it is splashed from the apertures.

l/Vhile the structure shown and described forms one preferred form of my invention it will be appreciated that various changes and modifications of structure may be resorted to or various features added or elinr inated Without departing in any manner from the spirit of the present invention as defined by the accompanying claim.

hat is claimed is:

A Sifter including a casing, a sieve removably disposed in the casing in a Way to be held against movement with respect to the casing during a sifting operation and for movement of the casing thereivith during such operation, and Water containers mounted in the casing longitudinally of the direc tion of motion of the casing during a sifting operation and having splash openings at their ends for the egress of Water from the containers to the casing as a result of surging of Water inthe containers incident to re ciprocation of the casing.

In testimony whereof, I am my signature, in the presence of tWo Witnesses.
