Year: 1878

page_text: LETTERS PATENT to Edwin Yates, of Glasgow, in the County of Lanark,
North Britain, Manager of the Cylde Galvanizing Works, for the Invention of
"IMPROVEMENTS IN BRUSHING AND CLEANING THE SURFACES OF GALVANIZED
AND OTHER METAL PLATES."
Sealed the 16th August 1878, and dated the 2nd March 1878.
PROVISIONAL SPECIFICATION left by the said Edwin Yates at the Office
of the Commissioners of Patents on the 2nd March 1878.
EDWIN YATES, of Glasgow, in the County of Lanark, North Britain, Manager
of the Clyde Galvanizing Works. "IMPROVEMENTS IN BRUSHING AND CLEANING
THE SURFACES OF GALVANIZED AND OTHER METAL PLATES."
This said Invention has for its object the brushing and cleaning of the surfaces
of sheet metal plates after they have been galvanized, tinned, or otherwise coated
in the molten metal pots by machinery instead of by hand as heretofore, all in a
more efficient and expeditious manner than hitherto.
And the nature and novelty of the Invention consist in the use and fitting of a
pair of revolving brushes in front of the rolls of an ordinary plate rolling and
pressing machine, for re-rolling or flattening the plates after being brushed by
hand.
The brushes are each preferably made in one, two, three, or more longitudinal
bars and rails, equally divided round eyes or arms on their spindles, and divided or
set so as to revolve at a high speed in the spaces between or opposite each other,
close together, so as to brush the upper and lower surfaces of the plates as they are
fed in at first by hand until the front end of the plates enter the pressing and
drawing rollers beyond, which then draw the plates through the brushes, which are
driven and revolved at a great speed in the different direction to that in which the
plate is moving and the pressing rollers running.
A wedge or trumpet shaped feeding-in mouth-piece is fitted across the whole front
of the brushes, wide enough for the broadest plate to be rolled and cleaned, and a
continuation of it is fitted between the brushes and the rollers to guide the plates
from the brushes to these.

page_text: The shafts of the brushes and rollers are erected to revolve in bush bearings in
the cast-iron side frames of this improved combined brushing and rolling plate mill
or machine, and the spindle of the upper or lower brush might be driven direct by
a belt and pulley or pulleys on it from any adjacent motive shaft, and which by
spur wheels at the other end might give motion to the other brush by its spindle,
both brushes revolving at the same speed towards each other; and when desired
guides may be formed at the edges and through between the brushes of the feeding-
in mouth-pieces for the guiding in of the plates, which would be placed in a heap
on a feeding-in table in front of the machine ready for being fed into the brushes
and straightening rollers as described. The plates are thus delivered, both cleaned
and flattened, from this combined brushing and rolling machine, direct from the
galvanizing vessel as they cool instead of at two operations as heretofore.
Although only one pair or set of brushes have been described, it will be evident
that two or more sets may be used, and a set of brushes might also be ranged on
the delivery side of the drawing and pressing rollers, and a pair of small feeding.
in rollers might be used in front of the brushes, instead of, or in addition to the
feeding-in mouth-piece.
And although this machine is essentially designed for brushing and cleaning the
surfaces of galvanized or tin-coated sheet metal plates, it is also applicable for
brushing, cleaning, or polishing other coated or non-coated sheet metal plates.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Edwin Yates in the Great Seal Patent Office on the 28th August
1878.
EDWIN YATES, of Glasgow, in the County of Lanark, North Britain, Manager of
the Clyde Galvanizing Works. "IMPROVEMENTS IN BRUSHING AND CLEANING THE
SURFACES OF GALVANIZED AND OTHER METAL PLATES."
My said Invention has for its object the brushing and cleaning of the surfaces of
sheet metal plates after they have been galvanized, tinned, or otherwise coated in
the molten metal pots by a combination or arrangement of machinery instead of by
hand as heretofore, all in a more efficient and expeditious manner than hitherto.
And in order that the full nature and novelty of my said Invention, and the
mode and means of performing the same may be properly understood, I shall now
proceed to describe the several Figures on the Sheet of Drawings which I have
hereunto appended for the purpose of showing the best arrangement I am at
present aware of for putting my Invention into effect or practice, the same reference
letters and numerals indicating the same or equivalent parts in all the Figures
where shown.
Figures 1, 2, and 3 are respectively a front elevation, a transverse sectional
elevation, and a plan with only part of the front table shown in the latter Figures,
all of one arrangement of the parts of my machine, or combination of mechanism,
constructed in accordance with and illustrative of my said Invention.

page_text: Referring to these Figures, 1, 2, and 3, the main part of the machine consists of
a pair of cylindrical plate-rolling, flattening, and drawing rollers 1, 1', carried in
bush bearing blocks 2 in the strong side fraines or housings 2, secured together by
the cross tie bars 211, and also in and on the strong sole plate or frame 3, bolted
down at 4 to a suitable foundation below, all as so far described being substantially
as heretofore used for making and rolling or pressing and straightening sheet metal,
having the shaft of the under roller driven direct from a first motive shaft by a
clutch coupling at 1", the lower roller 1 driving the top roller 11 by a pair of spur
pinions gearing into each other on the one end of their spindles outside the frame 2
when desired, and fitted with tightening-up screws 2111 at the top over the journal
bushes of the top roller 1¹.
The nature and novelty of the Invention consist in the use and fitting of a pair
of revolving brushes A, B, in front of the rollers 1, 1, of the ordinary plate rolling
and pressing machine, heretofore used for re-rolling and flattening the plates
they were brushed by hand.
after
These new brushes A, B, are each preferably made or formed of or in one, two,
three, or more longitudinal wood bars A, and mounted on iron rails a, equally
divided round and secured to eyes or arms 6 keyed on their carrying and revolving
spindles B, which are carried in journal bush bearing brackets C secured to the front
of the side frames 2, with the brushes A divided or set so as to revolve at a
high speed, either in the spaces between or opposite each other and close together,
so as to brush the upper and lower surfaces of the plates z as they are fed in
between them, as shown dotted in Figure 2, at first for a short distance by hand,
until the front end of the plates enter the pressing and drawing rollers 1, 11,
beyond the brushes, and which then draw the plates through the brushes A, B,
which are driven and revolve at a great spred in the different direction to that in
which the plate is moving, and the pressing rollers running as indicated by the
arrows in Figure 2.
A hollow conical or trumpet-shaped feeding-in mouth-piece D (in cross section,
Figure 2) is fitted across the whole front of the brushes secured to end brackets d
(Figures 1 and 3), wide enough for the broadest plate z to be rolled and cleaned in
the machine, and a continuation D' of this mouth-piece D is fitted between the
brushes A, B, and the rollers 1, 11, secured there at its ends to the frames 2, 2, at
some distance from each other, where the brushes A, B, work by the upper and
lower thin tie bars d, passing through these and reaching to near the rollers 1, 1',
all so as to guide the plates 2 through between the brushes to the rollers.
The shafts B of the brushes A, B, and those of the rollers 1, 11, are erected to
revolve in suitable bush bearings on the cast-iron side frames of this new or
improved combined sheet plate brushing and rolling mill or machine, and the
spindle B, either of the upper or lower brush A, B, might be driven by a pulley b¹
on it direct through a belt 6" passed over it from a pulley on any adjacent prime
motive shaft, and spur wheels 62 are mounted on the other end of their shafts B to
give motion to the second shaft of the other brush A, B, so that both brushes would
revolve at the same speed towards each other.
The plates would preferably be placed in a heap over each other on a feeding-in
table E in front of the machine, ready for being fed into and between the
brushes and straightening rollers, as described, through the guiding and steadying
funnel D, D¹, d¹; and when desired guides e, e, may be formed or fitted on the
table E or at the front of the feeding-in mouth-pieces D for guiding the plates z by
their edges through between the brushes. The plates are in this way first
thoroughly cleaned on both surfaces, so as to remove all the sand or loose matters
which may slightly adhere to them in the coating vessels by the swift revolving
action of the brushes A, B, and then flattened by the action of the roilers 1, 11, and
are thus delivered finished at one operation from this combined brushing and rolling
machine at the back Z of the rollers 1, 1', direct from the galvanizing vessel as
they cool, instead of at two operations, as heretofore.
Although only one pair or set of brushes A, B, have been described and shown in the

page_text: Drawings, it will be evident that two or more sets may be used, and that a set of
brushes might also be ranged on the delivery side of the drawing and pressing
rollers 1, 1, when desired, and that a pair of small feeding-in rollers might be
used in front of the brushes, instead of or in addition to the feeding-in mouth-
piece D.
Although only revolving brushes have been described and shown, these being
considered best, yet it will be understood that reciprocating brushes might be used
instead as an equivalent arrangement, worked either longitudinally or transversely,
or both on the upper and under surface of the plates, where the revolving brushes
are shown.
And although this machine is essentially designed for brushing and cleaning
the surfaces of galvanized or tin-coated sheet metal plates, it is also applicable for
brushing, cleaning, or polishing other coated or non-coated sheet metal plates
requiring this to be done.
Having now described the nature of my said Invention, and the manner of per-
forming the same, I have to state that I do not confine myself to the precise
details herein-before described or delineated, but what I consider novel and
original, and therefore claim as the Invention secured to me by the herein-before in
part recited Letters Patent is,―
First. The general construction or combination of the parts of a new or improved
machine or arrangement of mechanism for brushing and cleaning the surfaces of
galvanized and other metal plates, all substantially as herein-before described in
reference to and shown in the accompanying Drawings, or any mere modification
thereof.
Second. The application and use of revolving or other equivalent brushes A, B,
and guides D, D, d, e, to a plate rolling or flattening machine for brushing and
cleaning the surfaces of galvanized and other metal plates, all substantially as herein
described in reference to and shown in the accompanying Drawings.
In witness whereof, I, the said Edwin Yates, have hereunto set my hand
and seal, this Twenty-seventh day of August, in the year of our Lord
One thousand eight hundred and seventy-eight.
Witness,
