I FEWSTER PLAYER Tin Plato Manufacturer, Ystalyfera, Swansea Valley do hereby
declare the nature of this invention to be as follows:
It is a machine for cleaning and polishing tin and terne plates, and consists of a
box of two or more compartments, the lowest containing the bran or other cleaning
material and a pair of revolving brushes. The plate as it leaves the coating pot is
pushed into the first compartment through an opening which is edged with brushes to
prevent the escape of the contents; it is then carried by rollors through an opening
similarly guarded into the polishing compartment or compartments, and thence
by a peculiar arrangement of rollers is delivered on to a bench ready for the sorting
room.

I FEWSTER PLAYER, Ystalyfera, near Swansea, 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 is devised with the object of automatically effecting the cleaning and
polishing of tin and terne plates after removal from the coating pot by means of a
system of rollers, to which motion is imparted by any suitable means, and between
which and the chambers containing the cleaning material, the plates are conveyed to
the polishing device, whence they are discharged down an inclined plane ready for
removal and storing away.
In order that my invention may be the better understood I have appended the
accompanying sheet of drawings in which Figure 1 is an elevational view of my
improved apparatus showing the means which I adopt for imparting a reciprocating
motion to the polishers. Figure 2 is a similar view in section illustrating the
arrangement of the feeding rollers and cleaning chambers; and Figure 3 is a plan
of same.
The device according to my invention comprises a box or enclosing case A divided
into a number of chambers B. B B and C. C. Within the chamber B are arranged
three sets or pairs of propelling or feeding rollers D, D¹, D"; a pair of pressing
rollers H and the polishing plates or brushes G. In each of the narrow chambers B¹ B₁,
are also provided a pair of rollers E, E, for the purposes hereinafter more particularly
referred to. The chambers C, C', contain the cleaning material a a such for instance
as bran, which is retained in the chambers by means of horizontal valvular openings
formed centrally in the dividing walls, and which are closed in by means of
brushes or equivalents, 6, 61, 61, 6
The mode of operation is as follows, that is to say :-Each plate on removal from
the coating pot is introduced between the rollers E¹ which, propelling the plate
forward, passes it through the obstructing brushes into the cleaning material a in
the chamber C, whence it is pressed through the obstructing brushes 6¹¹ to the
rollers E, these latter now take up the propulsion of the plate, which, having passed
through the brushes 6 and 6 (and cleaning material a in the chamber C) is taken up
or gripped by the pair of rollers D" propelling said plate between the pressing rollers
or rotary polishers H or both, as may be desired, whence it is passed by the propelling
rollers D between the polishing plates or brushes G above referred to, where, by the
rapid reciprocating motion transinitted thereto, the tin or terne plate is brought to a
high degree of polish. From the polishing mechanism the plate is drawn by means
of the rollers D delivering or discharging it therefrom down the inclined plane c,
whence it may be removed and stored away.
From the foregoing it will be observed that the plate in passing through the
machine is partially cleaned by the cleaning material, and partly by the obstructing
brushes, the brushes 6 removing any of the cleaning material that may remain
:

the propelling rollers are contained in separate compartments or chambers, and the
cleaning material is prevented from obtaining access to such separate chambers by
means of the brushes b, 61, 61, 6¹¹, above described, the rollers will always be free
from corrosive influences and may with little trouble be kept constantly clean and
bright.
The reciprocating motion of the polishers G is obtained by means of bell cranks d
(Figures 1 and 3) pivoted at the elbows e and connected by link rods f to cranks g
the upper crank g being preferably mounted upon a pulley to which motion is
transmitted by means of a suitable belt or equivalent from the main shaft, or, if
desired, the shaft upon which the pulley h is mounted, may be provided with a
toothed wheel engaging with a similar toothed wheel upon one of the roller shafts, or
by other suitable means.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what
I claim is
First. The improved machine for cleaning and polishing tin and terne plates
substantially as herein described and shown in the accompanying drawings.
Second. In a tin and terne plate cleaning and polishing machine the method which
I adopt of disposing the carrying or propelling rollers in separate compartiments or
chambers substantially as herein set forth and shown.
Third. The mode of and means employed for preventing the egress of the cleaning
material from the chambers C (substantially as herein described and shown.
Fourth. The method which I adopt for imparting a reciprocatory motion to the
reciprocating polishers substantially as herein set forth and shown.
