and in the Machinery Used therefor.
1 HUGH BAIN of: 63 Queen Victoria Street, in the City of London, Manu-
facturers Agent do hereby declare the nature of my invention for IMPROVEMENTS
IN TINNING AND FINISHING TIN AND TERNE PLATES AND IN THE MACHINERY
USED THEREFOR to be as follows:-
To accomplish this I use a Bath which contains the coating metal.
This Bath is of a peculiar shape, see accompanying drawing, which represents a
transverse section through the Bath A, having one or more partitions B, for
separating the Tinning portion C. of the Bath from the finishing portion D and an
extended taper side which is so arranged that it admits two or more side grooved
guides D¹ so that two or more sheets or plates can be coated or finished together.
In connection with the guides referred to, I use a lifting apparatus E. for feeding
the machine F. automatically as they leave the molten metal.
I so arrange these guides together with a top and bottom plate G. G. upon the
tinning end of the Bath that they rub the sheets as they pass through the grease
floating upon the surface of the metal.
The side guides referred to are only used for the purpose of keeping the plates
in their course and need not be grooved, the plates merely entering in between
the two side guides and the surface plates.
The Bath is also so constructed that the finishing machine F consisting of a
number of rollers H mounted in a pair of side frames I. I. and geared together is
moveable so that the plates pass straight from the molten metal up between the
finishing rollers, or the finishing machine may be moved backwards above the
deep portion of the Bath which contains grease separated from the molten metal.
A portion of this machinery for coating can be made available for use with the
old system, so that at a small cost the old or present mode can be converted into
the new.
In operation when the sheets are a little below the bottom roller in the
finishing machine they are pushed forward under the partition which separates the
tinning portion from the finishing portion,-the sheets are then lifted up by a
cradle K between chilled surface plates G G¹ which may be chequered so as to
rub the plates, the said plates G G being caused to open slightly by the lift of
the cradle and as the cradle drops back, these surface plates are made to tighten
very tight on the surface of the plate and so clean off any scruff or impurities.

page_text: Improvements in Tinning and Finishing Tin and Terne Plates
and in the Machinery Used therefor.
I HUGH BAIN, of 63 Queen Victoria Street in the City of London, Manu-
facturers Agent do hereby declare the nature of my invention for IMPROVEMENTS
IN TINNING AND FINISHING TIN AND TERNE PLATES AND IN THE MACHINERY
USED THEREFOR 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 improvements in Tinning and finishing Tin and Terne
plates, obtained by a novel combination of tinning machine or apparatus whereby
I may in the same machine treat plates of different qualities, my machine occupying
little space, being simple in construction and economical in working; certain parts
of my machine being also novel in construction and arrangement.
The accompanying Sheet of Drawing shows in transverse section a machine or
apparatus embodying my invention.
A indicates the bath or pot, which is of a peculiar shape, having one or more
partitions B for separating the tinning portion C of the bath from the finishing
portion D; the extended tapered side A¹ of the bath is so arranged that it admits
two or more side guides E, enabling two or more sheets or plates to be coated or
finished together.
F is a lifting apparatus for feeding the sheets or plates automatically to the
finishing rolls G as they leave the molten metal.
The guides E together with the top and bottom plates (hereinafter called the
scrubbers) H, H, are so arranged that they rub the plates as they pass from
the grease, floating upon the surface of the metal, into the molten metal in the
bath C.
The side guides E are only used for the purpose of keeping the plates in their
proper course, and may or may not be grooved; the plates may simply enter
between the two side guides and the surface of the scrubbers H H.
.The bath is also so constructed that the finishing apparatus, consisting of a
number of rollers G mounted in a pair of side frames II and geared together by
the wheels K K K, is movable and may remain central, as shewn on the drawing,
to receive the plates from the baths C and N alternately, or be placed directly over
one bath or compartment, as may be desired.
I may place the rollers G over an ordinary bath or pot providing it with the
lifting apparatus F, and thereby adapt my system to existing plant at little cost.
The working is as follows:-
The sheets to be tinned are first passed down along the guides E and between
the chilled surface plates or scrubbers H H, (which may be chequered so as to rub
the plates) these scrubbers being caused to open slightly by the entrance of the
sheets and then tightened lightly on the surface thereof by the action of the
counterweight L, all scruff and impurities being thereby removed therefrom
the sheets then fall on to the cradle f of the lifting apparatus F, which lifts them
into the finishing rolls G, guided thereto by the plate M; and having passed
through the rolls, the coated sheets or plates are removed by hand, and so on
continuously.

page_text: If it is desired to operate upon Terne plates, the series of rollers G is slid or
moved over the bath N; the plates fed into this bath at O rest on the cradle f¹ and
are brought up by the lifter F to the finishing rolls, passing through them as in the
operation above described.
I may modify this combination of Tinning machine or apparatus by making
both sides alike and thus operate upon either tin or terne plates from both com-
partments, passing the plates alternately, or in any desired succession from one or
other compartment through a central series of rolls, being guided thereto by the
guides E E
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that
what I claim is
1. A machine or apparatus for tinning and finishing tin and terne plates, con-
structed, combined, and arranged to operate as hereinbefore described and shewn on
the accompanying drawing.
2. In a machine or apparatus for tinning and finishing tin and terne plates, a
bath or pot divided into two or more compartments each containing coating
material and a lifting apparatus, in combination with a central series of finishing
rolls through which the sheets or plates under treatment may be passed from one
or other compartment in any desired succession, substantially as described.
3. In a machine or apparatus for tinning and finishing tin and terne plates
having a bath divided into compartments, a series of finishing rolls arranged to be
passed from above one compartment to above another, substantially as described.
4. In a machine or apparatus for tinning and finishing tin and terne plates, a
guide having scrubbers cleaning the plate or sheet as it passes from the grease into
the molten metal, substantially as described and shewn.
5. In a machine or apparatus for tinning and finishing tin and terne plates, the
guide M descending below the grease and guiding the plates into the finishing rolls
as they are lifted out of the molten metal, substantially as described.
