'IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR RE-WORKING IRON
SHEARINGS PRODUCED IN THE MANUFACTURE OF SHEET IRON FOR TIN PLATES,
AND FOR OTHER PURPOSES."
"
My Invention consists of an improved method of and apparatus for cutting up
and preparing the shearings of iron sheets rolled for the manufacture of tin plates
or other purposes, and of an improved method of and apparatus for introducing
them into puddling furnaces, so as to facilitate their use in such furnaces.
The shearings herein referred to are those produced in the rolling of sheets in
packs" of various thickness, and consisting of a number of single sheets, and one
of the objects of the Invention is to separate these pieces before introducing them
into the puddling furnace, with a view to obtaining better results than when
working according to the plans now in use.
For the purpose of cutting up and preparing the shearings, I employ shears of
the ordinary construction worked in any convenient manner, and for the purpose
of separating the pieces of which such shearings are composed, I pass the said
shearings through one or more pairs of grooved and smooth rollers before they are
cut into short lengths. I connect these rollers with the shearing nechanism in such
a manner that a certain length of the shearings, say from one to two inches, is cut
off after having been passed through the said rollers.
.
After the shearings have been cut up and prepared, as above described, I place a
certain quantity of them in a hopper standing over the roof of an ordinary puddling
furnace, and connected with the interior of such furnaces by a suitable orifice,
preferably square or round. The bottom of said hopper is closed by a valve, which
Pries G71

page_text: is by preference conical, and sets in a seat whose sides are in a line with the sides
of the hopper.
To this valve is attached a rod which passes through a guide attached to the
hopper, so that it may rise and fall in a vertical direction, and to the upper end of
this rod I attach a lever and handle, by means of which the workman is enabled to
raise the valve to any height he may require, to allow of the contents of the hopper
to fall into the furnace.
To allow the heat of the furnace to pass through the valve and so to heat the
shearings after they have been placed in the hopper, as above described, preparatory
to passing them into the furnace, I perforate the valve with holes in such a manner
as will effect the required object, and to prevent the introduction of cold air into
the furnace through such perforations. I cover the top of the hopper with a lid or
cover, and if necessary, I connect the hopper with the flue or chimney of the
furnace by means of a pipe of the requisite size.
After the shearings treated as above described have been passed into the puddling
furnace, they are worked in the ordinary manner.

WILLIAM HENRY NEVILL, of Ferryside, in the County of Caermarthen.
IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR RE-WORKING IRON
SHEARINGS PRODUCED IN THE MANUFACTURE OF SHEET IRON FOR TIN PLATES,
AND FOR OTHER PURPOSES."
My Invention consists of an improved method of and apparatus for cutting up
and preparing the shearings of iron sheets rolled for the manufacture of tin plates
or other purposes.
The shearings herein referred to are those produced in the rolling of sheets in
packs of various thicknesses, and consisting of a number of single sheets, and one of
the objects of the Invention is to separate these pieces before introducing them into
the puddling furnace, or otherwise treating them with a view to obtaining better
results than when working according to the plans now in use. For the purpose of
cutting up and preparing the shearings, I employ shears of the ordinary construction
worked in any convenient manner, and for the purpose of separating the pieces of
which such shearings are composed, I pass the said shearings through one or more
pairs of grooved or other rollers before they are cut into short lengths, and I
connect these rollers with the shearing mechanism in such a manner that a certain
length of the shearings, say, from 1 to 4 inches is cut off after having 'been passed
through the said rollers.
And in order that my said Invention may be more clearly understood and
readily carried into effect, I will proceed, aided by the accompanying Drawings.
Figure 1 is a front elevation, Figure 2 is a side elevation, and Figure 3 is a plan
of apparatus constructed according to my Invention for cutting up and preparing
the shearings of iron sheets rolled for the manufacture of tin plates or other
purposes.
The shearings to be operated upon are placed in the feeding trough A, from
which they are passed between rollers B, B, of which one or more pairs may be
used, two pairs being shewn in the Drawing. These rollers are in the Drawings
shewn formed with grooves running around the same, but they may be of any
other pattern best suited to the nature of the shearings.
To the rollers B, B, an intermittent motion is given by means of a ratchet
wheel E, which is connected with the said rollers by a spindle B¹ working in
brackets attached to the main standard of the shears, or otherwise supported; such
spindle is capable of being thrown in and out of gear by means of the clutch
handle H.
The ratchet wheel E is set in motion by an eccentric F working on the spur
wheel shaft F, or by a pin fixed in the spur wheel G, and a lever or other
convenient arrangement, by which means in each revolution of the spur wheel G,
an onward motion is given to the rollers B of such length as may be desired.
The motion is so arranged that the length of the shearings to be cut off is
introduced between the shear blades C, C, when the upper blade reaches its highest
elevation.
The machinery is set in motion by the spur gear G, G³, and motion may be
given either by an independent engine, or by a strap and pulleys.
The pair of rollers B, B, driven by the shaft B', may communicate motion to the

page_text: other pair by intermediate gear, or motion may be given thereto in other suitable
and convenient manner.
I would here remark that in speaking of shearings of iron sheets rolled for the
manufacture of tin plates and for other purposes, I intend it to be understood as
including shearings of sheets of any description of iron or steel used for the said
purposes.
I would further remark that I have discovered that the method and apparatus
described in my Provisional Specification for introducing the said shearings into
puddling furnaces, so as to facilitate their use in such furnaces, do not possess such
an amount of utility as to render it advisable to give any further description
thereof, and for this reason I desire to disclaim, and I do hereby disclaim such
method and apparatus.
Having thus described the nature of my said Invention, and the mode I adopt
in carrying the same into effect, I would have it understood that what I claim is,
the improved method of and apparatus for re-working iron shearings produced in
the manufacture of sheet iron for tin plates and for other purposes, substantially as
herein shown and described.
In witness whereof, I, the said William Henry Nevill, have hereunto set
my hand and seal, this Seventh day of February, in the year of our Lord
One thousand eight hundred and eighty one.
