PROVISIONAL SPECIFICATION.
Improved Means for Skimming Molten Metal in Apparatus for
Tinning Iron or Steel Plates.
We DAVID JONES of Pontardulais and BENJAMIN JONES of Pontardulais.
trading under the name of D. and B. Jones Engineers and Ironfounders.
Pontardulais South Wales do hereby declare the nature of this invention to be as
follows:-
This invention relates to removing the scruff from the surface of the molten,
metal when tinning iron or steel plates.
Hitherto in other machines the plate during process of coating comes up through.
the metal which has scruff on its surface consequently it brings some of the scruff
with it thereby frequently giving the plate a rough surface.
Now according to our invention in order to attach our skimmer we make the
apparatus as follows:-
In a suitable casting we mount six rolls four of which work in the grease and
two in the metal such casting forming also the pot.
To the top of said casting we fix a lever and jointed rods at the end of which.
we joint a curved plate (the width of the rolls of the machine) extending down to
the metal and we also fix another curved plate as a guide for the sheet metal (this
plate we prefer to perforate) so that upon lifting the said lever it brings the first
named curved plate above the metal and when let down again the end scrapes the.
guide plate and skims the whole surface of the inetal and deposits the scruff at
the back of the machine so that the plate which is to be coated comes up through.
clean metal free from any scruff and thus gives it a bright smooth surface.

We DAVID JONES of Pontardulais and BENJAMIN JONES of Pontardulais.

Pontardulais, South Wales, 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 :-

guide plate and skims the whole surface of the metal and deposits the scruff at
the back of the machine so that the plate which is to be coated comes up
through clean metal free from any scruff and thus gives it a bright smooth
surface.
And in order that our said invention may be better understood we will now
refer to the drawing accompanying this Specification which represents our improved
apparatus (partly in section) for tinning iron or steel plates.
a shews the casting or vessel in which are mounted six rolls in the ordinary
way the rolls working in the grease and in the metal.
In the vessel a we fix a guide plate e and to one end of the rods d d we joint
at e e another curved plate f. The upper end of the rod d is jointed to rod g. and
the outer end of rod is jointed to lower end of rod the upper end of this latter
being jointed to lever i.
The action is as follows.
The sheets are passed through the rolls in the usual way but the surface of
the metal is skimmed and the scruff' deposited at the back of the apparatus at k. by
raising the lever i which brings the curved plate f. above the surface of the metal
into the position shewn in dotted lines and when the lever i. is let down again the
back of the curved plate . forces the scruff into the back part of the apparatus
at k and at the same time the edge of the plate scrapes the guide plate c.
The said guide plate is for guiding the sheets from the rolls 6 to the rolls 6'.
Z is the flux box.
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 :-
1. In combination with apparatus for tinning iron or steel plates the plates c
and j rods d. d h and i, all substantially as and for the purposes set forth.
2. The improved means for skimming molten metal in apparatus for tinning iron
and steel plates substantially as set forth.
