PROVISIONAL SPECIFICATION left by the said Benjamin Williams at the
Office of the Commissioners of Patents on the 22nd August 1882.
BENJAMIN WILLIAMS of 58 Cowbridge Road Canton Cardiff in the County
of Glamorgan Engineer "NEW OR IMPROVED MEANS OF AND APPARATUS
CLEANING AND POLISHING TIN PLATE
"
FOR
This Invention relates to certain new or improved means of and apparatus for
cleaning and polishing tin-plate in the manufacture thereof.
The object of this Invention is to effect mechanically in a more perfect manner
than heretofore the process of cleansing the tin-plates from oil in what is known as
the tin plate process.
For this purpose I employ a system of superposed rollers as hereinafter further
described through which the tin plates are passed said rollers serving first as guide
and delivery rollers, next specially formed bran gripping cleansing rollers then
fluted bran cleansing rollers and next guide and dusting and in some cases
polishing rollers.
The axes of these rollers are supported in side framings and are driven by
gearing or strap motion as desirable and below is arranged a trough. Above and
in front of the several bran rollers are bran hoppers provided with check plates
for supplying and regulating the supply of bran and at the sides of the trough
in which the operating rollers work are furnished elevators for raising up the
already used bran to the hoppers for reuse.
The first set of bran gripping rollers are made with pivoted arms or beaters
which are made to feather by a cam sleeve on the roller bodies so that as the
Dmine 611

page_text: motion of the rollers proceed the beaters at the lower position are open to their
greatest extent and take in between them and the body of the rolls a certain
quantity of bran which as the motion of revolution proceeds is squeezed out as
the feathering brings the beaters to a more closed position and this occurs just at
that point where the tin-plate is crossing the rolls in its traverse through the
machine so that a fresh cushion of bran is presented for cleaning purpose as each
beater passes the tin-plate being operated upon.
This heating will also break up any lumps that may be formed by cloging of the
bran and grease.
The rollers and beaters are to be covered with leather felt or cloth as required.

:
This Invention relates to certain new or improved means of and apparatus for
cleaning and polishing tin-plate in the manufacture thereof.
The object of this Invention is to effect mechanically in a more perfect manner
than heretofore the process of cleansing the tin-plates from oil in what is known as
the tinplate process.
For this purpose I employ a system of superposed rollers as hereinafter further
described through which the tin plates are passed, said rollers serving first as guide
and delivery rollers, next specially formed bran gripping cleansing rollers, then
fluted bran cleansing rollers, and next guide and dusting and in some cases
polishing rollers.
In the drawings: Fig. 1 is a longitudinal sectional view of apparatus constructed
according to this invention, and Fig. 2 is a plan but with hopper removed
A is side framing; B first feeding guide-rolls; C specially formed bran gripping
cleansing rolls; D fluted bran cleansing rolls; E and F dusting and polishing rolls,
these last serve also as delivery rolls, and burnishing, scratch or other brushes or
dollies or buffs may be added as required.
The axes of the rollers are supported in bearing on the side framing B, and are
driven by gearing or strap motion as desirable, indicated on the plan, and below is
arranged a trough G.
Above and in front of the several bran rolls is a bran hopper fitted with a
vibrating screen I. The hopper H is provided with check plates K, K1, K2 for sup-
plying and regulating the supply of bran and at the sides of the trough in which
the operating rollers work are furnished elevators L for raising up the already
used bran to the hopper for reuse.
The first set of bran gripping rollers C are made with pivoted arms or beaters Ct
which are made to feather by a cam sleeve C on the roller bodies so that as the
motion of the rollers proceed the beaters will open and take in between them and
the body of the rolls a certain quantity of bran which as the motion of revolution
proceeds is squeezed out as the feathering brings the beater to a more closed
position and this occurs just at that point where the tin plate is crossing the rolls
in its traverse through the machine so that a fresh cushion of bran is presented for
cleaning purpose as each beater passes the tin plate being operated upon. These
rolls C C C have imparted to them a reverse motion to that of the other rolls
and in the drawings the feathering operating parts are shown for illustration but
are not in correct relation to the tin plate x The closer position of the gripping
arms C should be towards the tin plate .
This beating will also break up any lumps that may be formed by any clogging
of the bran and grease.
The rollers and beater ends are to be covered with leather felt or cloth as
required.
The bran will fall through the openings under the hopper H on the movement of
the check plates K, K1, K2 taking place and will be received by the plate itself and
also by the rolls C and D and as each successive plate passes through, the lately
used bran will fall into the trough G and will be carried away by the archimedean

page_text: creeper M to the elevator L and so on. By these means a soft yet powerful and
continuous cleaning action will be secured.
Having now described the nature and particulars of the said Invention in such
wise that the same may be readily carried into practical effect I claim :-
"The new or improved means of and apparatus for cleaning and polishing
tin-plate operating and constructed in the manner and for the purpose herein
specified and shown by the drawings.
In Witness whereof I the said Benjamin Williams have hereunto set my hand
and seal this seventeenth day of February in the year of our Lord one
thousand eight hundred and eighty three
