PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Tin or Terne Plates and in the
Means or Apparatus employed therein.
We REES TAYLOR of Masons Road, Gorseinon, near Swansea, in the County of
Glamorgan, Tin Plate Assorter, and DAVID DAVIES of High Street, Gorseinon
aforesaid, Tin House Superintendent do hereby declare the nature of this invention
to be as follows:-
This invention has for its object to effect improvement in the manufacture of tin
and terne plates and apparatus employed therein, so as to secure economy in the
making of the plates by preventing waste of tin.
According to the present mode of finishing tin and terne plates as generally
practised the plates after being tinned are each brushed over and inserted into the
hot grease pot and then passed through rolls, coated with tin or a mixture of tin
and lead, and when the plate leaves the rolls there is left on the bottom edge a
margin of surplus tin which is called rib or list which list is not only not required on
the plate but is so much tin wasted for present purpose to the manufacturer.
According to our invention we obviate the loss caused by this waste of tin in this
list or rib by placing a bar of iron, steel, or copper coated with tin or other mixture,
or like bar, in the same pot as the rolls. This bar can be placed partially or wholly
in the grease as desired and consequently it will be of the same temperature as the
rolls. When the tinned plate leaves the rolls its bottom edge is placed by the operator
so that such edge shall come into contact with said bar whereby it takes off the
surplus list of tin therefrom and drops it to the bottom of the grease pot.
We use a trough with guides thereto in which the bar can be turned as desired.

and in what manner the same is to be performed, to be particularly described and

DESCRIPTION OF THE DRAWINGS.
Fig. 1 shews a side view and Fig. 2 a plan view of an arrangement of rolls and
bar with pots adapted for carrying out our invention.
a indicates the bar b, 6 the brackets for the support of the bar secured by screw
bolts and nuts to the framing c of the pot. d, d are rolls carried in bearings in the
framing c and these rolls d are driven by gear wheels e affixed in their several axes
and actuated in any ordinary or convenient manner.
This bar a can be placed partially or wholly in the grease as desired and
consequently it will be of the same temperature as the rolls d. When the tinned
plate leaves the rolls d its bottom edge is placed by the operator so that such edge
shall come into contact with said bar a whereby it takes off the surplus list of tin
therefrom and drops it to the bottom of the grease pot.
We can if desired use a trough with guides thereto in which the bar can be
turned as desired but such is not found generally necessary.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
-
In the manufacture of tin or terne plates the use of a bar of iron, steel, copper or
other suitable bar coated with tin or other mixture kept heated and adjacent to
tinning rolls so that tinned or terne plates having upon them a margin of surplus
tin or terne metal, called a list, may be rested upon said bar so as to cause said
plates to be relieved of such excess of coating metal and such excess to be rendered
available for re-use substantially as set forth.
