Machinery and Apparatus for Cleaning and
Polishing Metallic Plates or Sheets which are Coated with Tin
or other Metals.
We JOHN SIMMONS TREGONING Tin Plate Manufacturer of Llanelly in the
County of Carmarthen and WILLIAM EVANS of Llanelly aforesaid Tin Works
Manager do hereby declare the nature of this invention to be as follows:-
This invention relates to machinery and apparatus for cleaning and polishing
metal plates or sheets which are coated with tin or other metals and differs in its
construction and in its mode of operation from machines previously made which
roll the sheets through a series of rollers in the same direction, sheets being put
into the machine on one side and delivered on the other. In our invention we roll
the sheets or plates both ways forward and backward, the return motion being
effected automatically. We can by this invention put greater pressure upon the
plates as they pass through the machine and clean them more effectually than has
hitherto been done. The construction is as follows
We make a framing of any suitable material but preferably of iron having
provision made in same on the upper portion for one pair of feed rollers and for one
pair of cleaning rollers at suitable distances from each other for carrying the plates
in one direction, the lower portion of the framing has provision for carrying one
cleaning roller immediately beneath the upper cleaning rollers, that is the centres
of these three cleaning rollers are arranged vertically and one pair of feed rollers,
the rollers in the lower portion run in the opposite direction for carrying the plates
backward.
The plates or sheets when passed through the upper rollers fall on to a cradle
which oscillates by means of a crank motion on the machine and presses the sheets
into the bottom rollers and thus delivering them automatically on a suitable
receiver under the operators feed board.
The objects of our invention are
1st. To clean the surface of the plates more uniformly and effectually than has
hitherto been done.
2nd. To simplify the operation of branning by making it less important.
3rd. Reduction in labour, by delivering the plates on the same side of the machine
as worked by the operator.

Improvements in Machinery and Apparatus for Cleaning and
Polishing Metallic Plates or Sheets which are Coated with Tin
or other Metals.
We JOHN SIMMONS TREGONING Tin Plate Manufacturer of Llanelly in the
County of Carmarthen, and WILLIAM EVANS, Foreman in Tin Works of Llanelly
aforesaid 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 relates to improvements in machinery and apparatus for cleaning
and polishing metallic plates or sheets which are coated with tin or other metals.
In our invention we roll the plates or sheets both ways backward and forward the
return motion being effected automatically.

page_text: The construction is as follows
We make a framing of any suitable material but preferably of iron, having
provision made in same on the upper portion, for one pair of feed rollers, and for
one pair of cleaning rollers which are placed at suitable distances from each other
for carrying the plates or sheets in the forward direction. The feed rollers we
prefer to make of rubber rings on iron spindles. The cleaning rollers may be metal
or wood covered with any soft material-
--we prefer wool.
The lower portion of the framing has provision made in same for carrying one
cleaning roller immediately beneath the upper cleaning rollers, and for one pair of
feed rollers constructed as above described. The rollers in the lower portion of
framing revolve in the opposite direction for carrying the plates or sheets backward.
Between these two sets of rollers we fix an inclined board for sliding the plates or
sheets as they are passed through the upper rollers down to the lower rollers, or we
attach an oscillating cradle worked by a crank motion on the machine as may be
best adapted to the description of plates being operated upon. By this arrange-
ment of rollers we are able to put a greater pressure without injury to the plates
or sheets, than has been possible with machines previously made.
The operation is as follows
The plates or sheets being placed upon the feed board are passed singly through
the upper rollers and fall upon the inclined board-or upon the oscillating cradle,
as the case may be, and are by which forced backwards into the lower rollers and
are thus returned on to a suitable receiver under the operators feed board.
By these means we clean and polish the plates or sheets more effectually and
uniformly than has hitherto been done, and effect a great saving by making the
operation of branning less important, and a reduction in labour by delivering the
plates or sheets on the same side as the operator, which are the objects of our
invention.
And in order that our invention may be thoroughly understood and readily
carried into effect we will proceed to explain the same by the aid of the accom-
panying drawings.
A. Being the upper portion of framing.
B. The lower portion of framing.
C. The cleaning rollers.
D. The feed rollers.
E. The feed board.
F. The inclined board.
G. The oscillating cradle.
H. The cranks working cradle.
I. The driving pulleys.
K. Wheels driving feed rollers.
L. Wheels driving cleaning rollers.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that
what we claim is
First. The arrangement of the feed and cleaning rollers substantially as
described and for the purposes set forth.
Second. The rolling of the plates or sheets forward and backward at one
operation automatically as described and for the purposes set forth.
