Year: 1862

page_text: LETTERS PATENT to Matthew Dodds, of Bedburn Iron Works, in the
Parish of Hamsterley, in the County of Durham, Edge Tool Manufac-
türer, for the Invention of "IMPROVEMENTS IN MACHINERY FOR MOULDING,
FORMING, OR SHAPING ARTICLES OF IRON OR OTHER MALLEABLE METALS,
AND FOR SHEARING OR CUTTING BUCH METALS."
Sealed the 29th August 1862, and dated the 1st March 1862.
PROVISIONAL SPECIFICATION left by the said Matthew Dodds at the
Office of the Commissioners of Patents, with his Petition, on the 1st.
March 1862.
I, MATTHEW DODDS, of Bedburn Iron Works, in the Parish of Hamsterley,
in the County of Durham, Edge Tool Manufacturer, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR MOULDING,
FORMING, OR SHAPING ARTICLES OF IRON, OR OTHER MALLEABLE METALS, AND FOR
SHEARING OR CUTTING SUCH METALS," to be as follows:-
My improvements relate to machinery or apparatus of the character of that
for which Letters Patent were granted to me, dated the Eighth day of August
1860, No. 1923, and have for their object the obtaining of greater precision
or accuracy in the working of the operating parts. For this purpose the axes
of the rolls carrying the swages in place of being geared together by toothed
wheels are each provided with a crank connected by rods with a parallel or
other suitable motion operated by the driving axis to give a partial rotary
motion to such axes by which means whatever motion is given to one axis will
be simultaneously given to the other, and by these means insure the operating
surfaces of the swages acting in unison. I also, affix to the axis of the travel-
ling roll or swage and of the cutter a crank, the end of which is connected to

page_text: ono end of a rod, the other end of which rod rocks on a fixed pin, and the end
of the rock is thus made to form a moveablo fulcrum, against or within which
the pin of the crank acts, whilst the axis is moved to and fro by the connecting
rods as heretofore for the purpose of producing partial rotary motion of such
axis, in place of obtaining such partial rotary motion by a pinion taking into
the teeth of a stationary rack. By these, means greater accuracy or precision
in working may be obtained than by the use of the toothed gear.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Matthew Dodds in the Great Seal Patent Office on the
-30th August 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MATTHEW
DODDS, of Bedburn Iron Works, in the Parish of Hamsterley, in the County
of Durham, Edge Tool Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of March, in the year of our Lord One
thousand eight hundred and sixty-two, in the twenty-fifth year of Her.
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Matthew Dodds, Her special licence that I, the said Matthew Dodds,
my executors, administrators, and assigns, or such others as I, the said Matthew
Dodds, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
MACHINERY FOR MOULDING, FORMING, OR SHAPING ARTICLES OF IRON OR OTHER
MALLEABLE METALS, AND FOR SHEARING OR CUTTING SUCH METALS," upon the
condition (amongst others) that I, the said Matthew Dodds, my executors or
administrators, by an instrument in writing under my, or their, or one of
their hands and seals, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
I NOW KNOW YE, that I, the said Matthew Dodds, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-

page_text: My improvements relate to machinery or apparatus of the character or
that, for which Letters Patent were granted to me, dated the 8th day of
August 1860, No. 1923, and have for their object the obtaining of greater
precision or accuracy in the working of the operating parts.
In machines for moulding, forming, or shaping articles of iron and other
metals which are made according to my former Invention, described in my
Specification, filed in pursuance of my said Letters Patent of the 8th day
of August 1860, and with a pair of rolls the axes of the rolls carrying the
swages are geared together by means of toothed wheels fixed upon their
ends. In order that the swages or operating parts mounted upon these
rolls may act with greater accuracy or precision, I cause the axes of the
rolls in place of being geared together by toothed wheels, to be each pro-
vided with a crank, and those two cranks to be connected by rods with a
parallel or other suitable motion, operated by a driving axis or other motive
power to give a partial rotary motion to each of such axes, by which means
whenever motion is given to one axis, motion will also be simultaneously.
given to the other, so as to insure the operating surfaces of the swages.
acting in unison, and in machinery made according to my said former
Invention with one of a pair of swages or moulds fixed upon a travelling
roller, and the other swage or mould fixed in such a position that the swage or
mould upon the roller may pass over, and act in conjunction with the stationary
swage or roller, I dispense with the wheel or pinion and toothed rack described
in my said former Specification. And in order to cause the swages or opera-
ting parts of such machinery to act with greater accuracy or precision, I affix
to the axis of the travelling roll, a crank, the pin at end of which works in
an orifice at the end of a rod, the other end of which rod is attached to, and is
capable of moving on a fixed pin, and the end of the rod attached to the crank
is thus made to form a moveable fulcrum, against or within which the pin of
the crank acts, whilst the axis of the roller is moved to and fro by the
connecting rods as described in my said former Specification, for the purpose
of producing partial rotary motion of such axis, for the purpose of causing the
swages or moulds to act in conjunction upon a piece of metal placed between
them.
And, in constructing machinery for shearing or cutting iron, constructed (in
other respects) according to my said former Invention, I dispense with the
spur wheel or pinion upon the axle of the circular cutter, and also the fixed
rack described in my said former Specification. And I fix upon the axle of
the circular cutter a crank, the pin of which works in an orifice at the end of
a rod, the other end of which is attached to, and is capable of rocking or

This apparatus is composed of two machines marked respectively A and B.
each of which, (though shewn connected together,) may be worked or used
alone, and may be made separately; Figures 2 and 3 represent two opposite
side views of the machine A; and Figure 4 represents a side view of tho
machine B.
In each machine a, a, represents the main framing. The machine A has
a pair of rolls mounted in bearings, and carrying the swages or moulds b, b..
Each of these rolls is provided with a crank b' fixed upon one end of its axis.
Each of the connecting rods c, is at one end connected with the crank pin of
one of the rolls, and at the other end. is connected to a pin c', standing out
from the sliding plate or piece d, which is capable of sliding horizontally.
in the stationary framing a'. The sliding plate or piece is moved to and fro
in the framing by means of the link or connecting rod'd', one end of which
is connected with the pin c, and the other end with the crank pine of the
crank e'. The crank e' is formed upon, or is affixed to the axis or shaft e³,
which is supported in bearings a², carried by the main framing as shewn.
Upon the shaft or axis e is affixed the cog or toothed wheel by which
rotatory motion may be given to that shaft from a steam engine, or other suitable
power, and rotary
, and rotary motion given to such shaft or axis e². The crank e' by means
of the connecting rod d', will give a to-and-fro motion to the slide d, and thence
by the rods c, c, give motion to the crank arms b', 6', and thus impart a partial
rotary motion to the axes of the rolls b, b, alternately first in one direction, and
then in the other. The machine B has a travelling roll h³ with a swage or
mould attached to it. The roll is fixed upon the axis h, which is supported
in the bearings, h, at or near to the ends thereof, and each of those bearings
is capable of sliding freely to and fro between the stationary guides a³, a³,

page_text: forming part of the main framing. This sliding motion of the two bearings of
the axis h, is obtained by means of connecting rods or links i, i, which are
operated by the cranks e¹ and ³, formed on or affixed to the shaft or axis e².
Upon the axis of the roll h³, is also affixed an arm 1, (shewn in dotted lines in
Figure 4), the outer end of which is by pin joint connected to one end of the
fulcrum rod 1, the other end of which is capable of vibrating on a pin l³
affixed to the main framing, by which as the axis of the roll h³ is moved
to and fro horizontally, the roll will be caused to make a partial rotary motion
alternately first in one, and then in the opposite direction, so that the swage
or mould upon the roll, shall by the travelling and consequently partial
revolution of the roll be caused to coincide and act in conjunction with the
stationary swage or mould m, upon a piece of metal to be moulded or
shaped.
Figures 5 and 6 shew a rolling cutter g fixed upon the axis h so as to act
with a stationary cutter o for cutting purposes. The axis h is furnished with
bearings sliding between guides a³, a³, and with connecting rods i, for giving
motion to them, and also with an arm fixed to the axis h, and a fulcrum rod/¹
in like manner as in the machine B.
Having thus described the nature of my said Invention, and the manner
in which the same may be performed, I would have it understood that I do
not claim any of the mechanical elements or parts, or any of the machinery
or apparatus herein described or shewn in the said Drawing as being separate
or apart from the combination and application thereof herein described any
part of my said Invention.
In witness whereof, I, the said Matthew Dodds, have hereunto set my
hand and seal, this Twenty-sixth day of August, in the year of our
Lord, One thousand eight hundred and sixty-two.
MATTHEW DODDS. (L.s.)
