hereby declare the nature of this invention to be as follows:-
A cylinder made of any suitable material, in one or more parts, having at one
end an aperture; against the aperture sponge or other suitable material is
held in position by a ferrule or other suitable attachment. To the other end
of the cylinder, sponge or other suitable material may be attached by suitable
means.
The cylinder to be filled or charged with water. Shaking the cylinder whilst
holding the aperture-end downwards, the water percolates through the aperture
to the sponge or other material and is absorbed by same. Applying the wet
sponge to surface of slate & rubbing gently, the slate is cleaned. Applying
the reverse end of cylinder with dry sponge, the surface of slate is dried. This
appliance may be used in several modified ways, and with or without sponge or
other material.

I, JOHN ISAAC RICHARDS, of Round Pit Brickworks, Llansamlet, R.S.O., Wales,
Brickmaker, do hereby declare the nature of this invention and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement:-
My invention relates to a slate cleaner for the use of scholars and others, the
object being to provide a handy and cleanly application for the purpose. In
carrying my invention into effect I proceed in or in about the following manner
making reference to the accompanying drawing which is a longitudinal section.
I provide a tubular receptacle a for containing the water b. The receptacle is
entirely closed at one end and may or may not have attached to it in any suit-
able manner a piece of sponge or other suitable material c and I prefer that a
piece of such material shall be attached to the said closed end.
and open end of the receptacle is inserted the tubular plug or stopper having
The plug
at the outer end the piece of sponge or other suitable material e.
may be screwed into a or made retainable therein by a somewhat taper cork

of d into the end of a.
In use the plug d is removed and the receptacle a charged with water and
the plug d replaced. Then by inverting the appliance so that the sponge e is
downwards and shaking it, the water will be caused to percolate through the
sponge. The so moistened sponge may then be rubbed over the surface of the
slate to be cleaned, and when a dry piece of sponge is provided on the appli-
ance I apply it to the surface of the slate by rubbing so as to dry the parts
moistened by the wet sponge at the other end of the appliance.
Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same is to be performed, I declare that what
I claim is
Slate cleaners each consisting essentially of a tubular receptacle for contain-
ing water, one end of the said receptacle being permanently closed and furnished
or not on its exterior with a piece of sponge or other suitable material, the other
end of the said receptacle being open and provided with a removable and tubular
plug or stopper open at both ends and having at its exterior end a piece of sponge
or other suitable material, the whole substantially as described in the above
specification and exemplified by the accompanying drawings.
