LETTERS PATENT to Joseph Rushton Turnock, of the Yspitty Iron and Tin
Plate Works, Llanelly, South Wales, for the Invention of IMPROVEMENTS
IN THE MANUFACTURE OF TIN AND TERNE PLATES, AND IN APPARATUS
THEREFOR."
PROVISIONAL SPECIFICATION left by the said Joseph Rushton Turnock
at the Office of the Commissioners of Patents on the 24th April 1879.
JOSEPH RUSHTON TURNOCK, of the Yspitty Iron and Tin Plate Works, Llanelly,
South Wales. "IMPROVEMENTS IN THE MANUFACTURE OF TIN AND TERNE PLATES,
AND IN APPARATUS THEREFOR.”
This Invention relates to brushing the plates in the finishing process. Instead of
brushing each sheet by hand as at present is done by the "washman" (technically
called "washing "), I place a pair or more of brushes (kept sufficiently close together
by means of springs or other suitable device) in such a way that the attendant has
only to deliver the plates to the brushes and the "washing" is done mechanically.
In order to carry out this process to the best advantage either of the following
methods may be adopted as may be found most desirable, or other modifications
may be made to suit special circumstances. 1st. The brushes may be so arranged
that the attendant can take up a plate at a time and with his tongs push it between
the brushes, either entirely or only for a distance, when it may be engaged by
rollers or other means of drawing it entirely through. 2nd. The attendant may
deliver the plates direct to rollers placed above or before the brushes, which rollers
shall push the plate between the brushes until it is engaged, as before described; or
if the rollers are placed above the brushes the plate may be allowed to drop by its
own weight. 3rd. The attendant may drop the plate into a "pot," and it may then
be raised by a cradle either to a pair of rolls which would push it up through the
Dmins G31

page_text: brushes, or direct through the brushes either entirely or only far enough for it to
be engaged by a pair of rollers, which shall complete the process of drawing the
plate up. Another way in which the brushes can be placed when desirable is so
that they only brush one side at a time, in which case of course they would not be
set opposite to one another.
According to circumstances the brushes may either be made into a separate
machine or they may be used in the finishing pot in connection with rollers (for
instance, beneath the rolls of a Cookley set, or beneath or between the rolls of a
Morewood set, provided the rolls are far enough apart); or otherwise, they may
either be stationary or rotative as found most desirable.

This Invention relates to brushing the plates in the finishing process.
Instead of brushing each sheet by hand as at present is done by the "washman"
(technically called "washing "), I place a pair or more of brushes (kept sufficiently
close together by means of springs or other suitable device) in such a way that the
attendant has only to deliver the plates to the brushes and the "washing" is done
mechanically. In order to carry out this process either of the following methods
may be adopted as may be found most desirable, or other modifications may be
made to suit special circumstances. 1st. The brushes may be so arranged that the
attendant can take up a plate at a time and with his tongs push it between the
brushes, either entirely or only for a distance, when it may be engaged by rollers
or other means of drawing it entirely through. 2nd. The attendant may deliver the
plates direct to rollers placed above or before the brushes, which rollers shall push the
plate between the brushes until it is engaged, as before described; or if the rollers
are placed above the brushes the plate may be allowed to drop by its own weight.
3rd. The attendant may drop the plate into a "pot," and it may then be raised by
a cradle either to a pair of rolls which would push it up through the brushes, or
direct through the brushes, either entirely or only far enough for it to be engaged
by a pair of rollers, which shall complete the process by drawing the plate up.
Another way in which the brushes can be placed when desirable is so that they
only brush one side at a time, in which case of course they would not be set
opposite to one another.
According to circumstances the brushes may either be made into a separate
machine or they may be used in the finishing pot in connection with rollers (for
instance, beneath the rolls of a Cookley set, or beneath or between the rolls of a
Morewood set, provided the rolls are far enough apart); or otherwise, they may
either be stationary or rotative as found most desirable.
The arrangements which I prefer are indicated by the Drawings annexed.
As the plates come from a coating pot they are passed into a dipping pot con-
taining heated grease, and in which there is a cradle or lifter which raises the plates
one at a time between a pair of brushes. As the plates rise they are taken by the
tongs of the workman and passed into a finishing pot, and the finishing is conducted
in the usual manner.
Figure 1 shows an end view of a pair of fixed brushes; Figure 2 shows a simple
frame (end view) in which they may be placed.
The brushes may be made to press against one another by any of the well known
means of springs, levers, or screws. They may if desired be made rotative, and
worked by any of the well known means of straps or cogwheels.
The cradle for raising the plates may be of the usual form, and may be worked
either by hand, foot, or power. The frames for the bushes are represented in
Figures 3, 4, 5, 6, and 7, Figures 3 and 4 representing what may be called the
"handle" or "steel" has holes in it for pins in counterpart (Figures 5 and 6) to go
through; Figures 5 and 6 show the other portion of brush "steel" with fixed or
moveable pins; Figure 7 shows brush frame or "steel" (without the hemp or other
material which may be used) showing the two parts in position.
The brush is made by placing the counterpart in a frame with the pins standing
up, the hemp or other material is then placed evenly along the length required, and
the "handle" is then pressed down upon it until the pins can be engaged by the
!

page_text: nuts or wedges, when it can be tightened up as required. If roller brushes are
used they may be made in any of the ordinary modes of making circular brushes of
similar materials; Figure 8 shows an end view of a pair of brushes in a frame; and
Figure 9, a plan of the same.
When employed in connection with rollers the brushes may be made of any
suitable refractory fibrous or elastic material, as "asbestos."
Figure 10 represents a simple way by means of a lever of keeping the brushes
pressed against one another.
Figure 11 represents a transverse section, and Figure 12 a longitudinal section
of a brushing machine such as I prefer to employ. The cradle a for raising the
plates is a modification of the well known "Cookley" cradle, and may be worked
in the same way, or as illustrated by weighted lever b, moved by hand, foot, cam,
eccentric, or other power; the guides marked c, c, c, c, may either be attached to
brush frame, as shown, or to side of pot in the usual manner; d, d, d, represent the
ordinary Cookley fingers for pushing the plate into an upright position in the cradle;
e represents ordinary dipping pot; f, plate being put in. When rolls are used
below the brushes they of themselves form the guide, and the plate is delivered to
the rolls in the ordinary manner, the brush frame being merely fixed on the pot
over the rolls; so likewise if the brushes are placed between the two pairs of rolls
the rolls would be actuated in the well known way and would push and pull the
plates through automatically.
Having thus described the nature of my said Invention and the manner of per-
forming the same I would have it understood that I claim,―
First. The use of fixed or revolving brushes for the purpose of brushing or
washing tin or terne plates, as herein set forth.
Second. The combination of a cradle or lifter and automatic brushes, the cradle
or lifter raising the plate and causing it to be passed between the brushes, as herein
set forth.
In witness whereof, I, the said Joseph Rushton Turnock, have hereunto set
my hand and seal, this Twenty second day of October, in the year of our
Lord One thousand eight hundred and seventy nine.
