PROVISIONAL SPECIFICATION.
Improved Apparatus for Cleaning and Polishing Metal and other
Surfaces.
We WILLIAM JAMES GRADWELL of 376 Rochdale Road, Mechanic, and WILLIAM
BAKER of 6 Upper Vauxhall Street, Wool Merchant, both of Manchester in the
County of Lancaster do hereby declare the nature of this invention to be as
follows:-
-
This invention is intended chiefly to be used with powdered emery or other
suitable polishing material in a powdered state, for the purpose of cleaning and
polishing steel, brass or other metal surfaces, but it may also be used (either with
or without polishing powder) for cleaning and polishing plate or other glass and
various other surfaces requiring to be cleaned and polished.
The invention consists essentially of a kind of brush or scrubber made with a cork
surface or surfaces bedded into or otherwise securely attached to a back or foundation
of wood or other suitable material.
The surface may be made either flat concave or convex according to the purpose
to which it is to be applied.
A convenient form of our invention to be used by hand for ordinary cleaning and
polishing purposes may be made with a wooden or other back somewhat of the size
aud form of a sinall clothes brush.
The face of the wood is bored all over with a series of holes (say) from one quarter
to half an inch diameter and preferably slightly coned. Into these we insert tightly
a series of corresponding pieces of cork somewhat similar to the corks used for
ordinary phials, the said corks projecting (say) from one eighth to one quarter of
an inch from the wood and with their surfaces level.
By these means we form a kind of brush, or scrubber, with a cork surface which
may be dipped into emery or other polishing powder and used for a variety of domestic
or other cleaning or polishing purposes.
Instead of having a number of conical or cylindrical pieces of cork to form the
working surface, it may be formed of a single piece of cork bark let into or otherwise
securely attached to the back or foundation, the surface being preferably corrugated
or grooved transversely, diagoually or otherwise, so as to form thereon recesses to
hold the emery or pohshing powder; but I prefer to make the surface of a number of
smaller pieces as above described as being more efficient, also more economical in
first cost, and more easily repaired in case of a portion becoming worn away or
broken.
It will be evident that cylindrical brushes or scrubbers with a cork surface can also
be made on this principle and driven by power for a variety of other cleaning and
polishing purposes.

Improved Apparatus for Cleaning and Polishing Metal and other

BAKER of 6 Upper Vauxhall Street, Wool Merchant, both of Manchester in the
County of Lancaster do hereby declare the nature of this invention and in what
[Price 8d.].

page_text: manner the same is to be performed, to be particularly described and ascertained in
and by the following statement:-
This invention is intended chiefly to be used with powdered emery or other suitable
polishing material in a powdered state, for the purpose of cleaning and polishing
steel, brass, or other metal surfaces, but it may also be used (either with or without
'polishing powder) for cleaning and polishing plate, or other glass, and various other
surfaces requiring to be cleaned and polished.
The nature of the said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the annexed sheet of drawings and the following explanation thereof.
In the annexed drawing Fig. 1. is a face view and Fig. 2 a half elevation and
section of a small haud polisher made according to our invention, but the form size
and other details may be varied considerably without departing from the chief
features of our invention, which consists essentially of a kind of brush or scrubber
made with a cork surface or surfaces, bedded into or otherwise securely attached to a
back or foundation of wood or other suitable material. The surface may be
made either flat concave or convex according to the purpose to which it is to be
applied.
The drawing represents for the sake of illustration a convenient form of our
invention to be used by hand for ordinary cleaning and polishing purposes, and is
made with a wooden or other back a somewhat of the size and form of a small
clothes brush.
.
The face of the wood a is bored all over with a series of holes (say) from one quarter
to half an inch in diameter and preferably coned as shown. Into these we insort
tightly a series of corresponding pieces of cork b, somewhat similar to the corks used
for ordinary phials, the said corks projecting (say) from one eighth to one quarter
of an inch from the wood, and with their surfaces level.
By these means we form a kind of brush or scrubber with a cork surface which
may be dipped into emery or other polishing powder and used for a variety of
domestic or other cleaning or polishing purposes.
Instead of having a number of conical or cylindrical pieces of cork b to form the
working surface, it may be formed of straight pieces, or of a single piece of cork
bark let into or otherwise securely attached to the back or foundation a the surface
of the cork being preferably corrugated or grooved transversely diagonally or
otherwise so as to form thereou recesses to hold the emery or polishing powder, but
we prefer in most cases to make the surface of a number of smaller pieces as above
described as being more efficient, also more economical, in first cost, and more easily
repaired in case of any portion becoming worn away or broken.
It will be evident that cylindrical discoidal, barrel-shaped, or other rotary brushes
or scrubbers with a cork surface can also be made on this principle and driven by
power for a variety of other cleaning or polishing purposes.
It will also be evident that the same surface on a larger scale may be used as a
door mat for cleaning the dirt from boots.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
The improved apparatus for cleaning and polishing metal and other surfaces
consisting of a kind of brush or scrubber of convenient form made with a cork
surface or surfaces bedded into or otherwise securely attached to a back or foundation
of wood or other suitable material substantially as hereinbefore more particularly
described.
