Machinery or Apparatus therefor.
I, GRIFFITH ELIAS, of Garnant, Cwmaman, in the County of Carmarthen, Tin aud
Terno Plato Manufacturer, do hereby declare the nature of this invention to be as
follows:
This invention, which relates to that stage in the process of producing tin and
terne plates at which they are immersed in the " grease pot" for removal of superfluous
coating, consists in means whereby the operation is facilitated and expedited.
According to this invention the rolls between which the plates are delivered after
immersion are extended longitudinally across the bath, one pair of rolls being
immediately above the other. The frame of the machine rests on brackets at one sido
of the pot which are specially constructed to admit of ready change of rolls. By
means of springs acted upon by set screws each pair of rolls is tightened separately
to regulate the coating of tin or terne metal used for coating the plates. The upper
rolls may, if desired, consist of a series of three.
The space intervening between the rolls and one side of the pot is divided trans-
versely into two equal compartments or divisions by a guide situated midway between
the ends of the pot. This guide is made moveable so as to accommodate various sizes
of plates. Additional moveable guides are also fitted towards each end of the machine.
The "washman or attendant appointed to immerse the plates in the bath deposits the
same into the said divisions.
"
By means of a cradle actuated from a bandle operated by a second operator the
plates are then raised so that one end or side thereof is grasped between the lower
pair of rolls from which the plates pass to the upper rolls. As the plates issue from
between the upper rolls they are withdrawn by the second operator aforesaid who is
provided for the purpose with tongs of different lengths a pair of which he holds in
cach hand, the longer pair being intended for grasping the plates farthest from him
and the shorter pair for seizing those nearer.

page_text: The second operator is enabled to actuate the cradle, as aforesaid, to withdraw the
plates as they issue from between the upper rolls and to deposit them on the cooling
grate without checking the rapidity of action of the washman in immersing the
plates.
Under this invention production is expedited and economy in labour effected.

Improvements in the Froduction of Terme and Tin Plates and in
Machinery or Apparatus therefor.
I, GRIFFITH ELIAS, of Garnant, Cwmaman, in the county of Carmarthen, tin
and terne plate manufacturer, 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 :-
This invention, which relates to that stage in the process of producing tin and terno
plates at which they are immersed in the " grease-pot" for removal of superfluous
coating, consists in means whereby the operation is facilitated and expedited.
According to this invention the rolls between which the plates are delivered after
immersion are extended longitudinally across the bath, one pair of rolls being
immediately above the other. The frame of the machine rests on brackets at one side
of the pot which brackets are specially constructed to admit of ready change of rolls.
By means of springs acted upon by set screws each pair of rolls is tightened separately
to regulate the coating of tin or terne metal used for coating the plates. The upper
rolls may, if desired, consist of a series of three.
The space intervening between the rolls and one side of the pot is divided trans-
versely into two compartments or divisions by a guide situated inidway between the
ends of the pot. This guide is made movable so as to accommodate various sizes of
plates. It keeps apart the plates as they are raised for presentation to the rolls.
Additional guides are also fitted towards each end of the machine. The "washinan
or attendant appointed to immerse the plates in the bath deposits the same into the said
divisions on either side of the middle guide.

page_text: By means of a cradlo actuated from a handle operated by a second operator the
plates are then raised so that one end or side thereof is grasped between the lower
pair of rolls from which the plates pass to the upper rolls. As the plates issue from
between the upper rolls they are withdrawn by the second operator aforesaid
who is provided for the purpose with tongs of different lengths; a pair of which he
holds in each hand, the longer pair being intended for grasping the plates furthest
from him and the shorter pair for seizing those nearer.
The second operator is enabled to actuate the cradle, as aforesaid, to withdraw the
plates as they issue from between the upper rolls, and to deposit them on the cooling
grate without checking the rapidity of action of the washman in immersing the
plates.
Under this invention production is greatly expedited and increased and economy in
labour effected.

sheets of drawings, Fig. 1 represents a front elevation, Fig. 2 a back elevation,
Fig. 3 a plan, and Fig. 4 a part end view and transverse section of a grease-pot
arranged and fitted in accordance with this invention for facilitating and expediting
the manufacture of tin and terne plates.
Extending longitudinally across the grease-pot are the rolls A A and A'A' arranged
in pairs, one pair being above the other. The frame B which carries the rolls rests
at one side of the pot on the brackets C which are not, as heretofore, rivetted or other-
wise rigidly fastened to the grease-pot, but are deposited over the sido thereof and
are furnished with set screws for vertical adjustment. This arrangement of the frame
and form of brackets greatly facilitate a change of rolls. By the springs E and levers F
acted upon by the adjusting nuts G the respective pairs of rolls are independently
tightened or slackened at will and the depth of coating retained by the tin and terne
plates is thereby regulated. Instead of being a pair of rolls only, the upper set may
consist of three, if desired. The space between the rolls and one side of the pot is
divided transversely into two compartments by a guide H which is adjustable to
accommodate platos of different widths. This guide keeps apart the plates as they
are raised and presented to the lower pair of rolls A¹ A¹.
Additional similar adjustable guides I are provided towards each end of the
machine.
The washman or attendant appointed to immerse the plates in the bath deposits the same
therein alternately or otherwise on each side of the guide H, and, by means of the
cradle K operated upon by a second attendant, the plates are raised to and grasped
between the lower pair of rolls A' A'. The plates are raised, either two at a time or
two at one time and one at another, that is to say, one or other of the divisions or
compartments will bo always open to the washman whose action is not interrupted.
From the rolls A' A' the plates pass to the rolls A A between which they are grasped. As
the plates issue from between the rolls A A they are seized by the second operator aforesaid
who is provided for the purposo with tongs of different lengths a pair of which he holds
in each hand, the longer pair being used for grasping the plates furthest from him and
the shorter for seizing those nearer. The second operator is enabled to withdraw the
plates as they issue from the upper rolls and to deposit them on the cooling grate
without checking the rapidity of action of the washman in immersing the plates in
the bath.
By the use of the divided grease pot, in which this invention consists, the
output of plates is greatly increased and there is a saving in labour, tin and
palm oil..
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In the manufacture of tin and terne plates, the use of an adjustable guide such
as H dividing the bath of the "grease pot" into compartments whereby with the same
number of operators as heretofore the immersion of such plates in the bath and

page_text: delivery from the bath are greatly expedited and the number of plates produced in a
given time largely increased, substantially as hereinbefore described.
2. In the manufacture of tin and terno plates, the use, for delivery of the plates
from the bath of the grease pot, of rollers such as A A and A'A' extending
longitudinally over the bath and carried in bearings in a frame such as B resting at
one side in brackets such as C hung over the side of the grease-pot and readily
removable, substantially as herein before described.
3. In the manufacture of tin and terne plates the uso for governing the space
between the rolls of each pair of rolls A A and A' A' of springs such as E, levers F
and adjusting nuts G, whereby the depth of coating retained by the plates is
controlled and regulated, substantially as hereinbefore described.
