My invention relates to new and useful improvements in slate Cleansers and .driers, the object of which is to provide a neat, couvenient, and inexpensive device for school pur` poses. j

A description ofv my invention is fully set forth in the following specification, and `the specific points of novelty mentioned in the claims.` i

` j Referring to the annexed drawings formtion of the cleansing end inverted. Fig. 4 represents a side elevation, and a plan view,

respectively, of the perforated tube or cylinder, the` cleansing and drying adjuncts detached therefrom. Fig. 5 represents sectional and plan views of the water reservoir removed from th`e cylinder. Fig. 6 represents Y sectional and plan views' of the sponge cup detached.'

Similar letters of reference indicate corre- Y `1 sponding parts throughout the different views.

, A designates a hollow tube or cylinder that may be constructed of Wood, metal or any suitable material; sheet metal, however, is thought preferable, and which may be nickel plated or otherwise ornamented; this cylin- Ader is provided with perforations (b) (b)`dia metrically opposite to each other.

B represents a reservoir to contain wat-er,

` and which is constructed of rubber, in cylindrical form having a spout (c) through which an outlet is afforded to the water; this reservoir is placed in the middle portion of the cylinder, to expose the sides thereof to the lingers, through the perforations (b) (b) in the cylinder. Y c j C designates a cup having a small opening (c) in the bottom thereof, and adapted to tit in one end of the cylinder, so that the spout .A

(c) may project through the opening (c'). D designates absorbent material, preferably sponge, suitably secured in the cup said cup provided with inwardly projecting teeth or serrations which penetrate the sponge sufficiently to effect a substantial engagement therewith. The inner portion of the sponge has a cavity (e) intowhich the spout (c) prosy C by having the crimped or beaded edges (e) ofin the cylinder, as is shown in Fig. 3; the reservoir being easily shifted toward the drying end of the cylinder.

Having fully described my invention, I claim.-
