Year: 1856

page_text: LETTERS PATENT to Samuel Fox, of Deepcar, Sheffield, for the Invention
of "IMPROVEMENTS IN MACHINERY FOR DRAWING WIRE AND TUBES."
Sealed the 19th May 1857, and dated the 19th November 1856.
PROVISIONAL SPECIFICATION left by the said Samuel Fox at the
Office of the Commissioners of Patents, with his Petition, on the 19th
November 1856.
I, SAMUEL Fox, of Deepcar, Sheffield, do hereby declare the nature of
the Invention for "IMPROVEMENTS IN MACHINERY TOR DRAWING WIRE AND TUBES,"
to be as follows:-
This Invention has for its object improvements in machinery for drawing
wire and tubes. For these purposes, the chain to which the drawing pliers
are attached passes under a guide pulley, and then ascends and is made fast
to a pulley on an axis above, and its end is fixed to such pulley. The axis
on which the pulley is placed receives a constant rotatory motion from any
suitable power, which gives motion also to the drum on which the wire is
wound. The pulley is at times locked to the axis by projections or clutches,
which, when the pulley has made a complete revolution, are withdrawn by
inclines on the face of the pulley, and the workman may stop the revolution
of the pulley before it completes a revolution by means of a lever catch, the
end of which, when desired, is made to enter a hole in a collar with inclines,
which is also on the axis, and towards which the pulley is constantly pressed
by a spring, and such collar is arranged to be connected to a fixed collar on
the axis. The drums on which the wire is wound are driven in the ordinary
manner, but apparatus is applied in order to stop their rotation with greater
convenience. On the axis of a drum a collar is affixed, having on it inclines

page_text: So
and clutches, and the boss is formed with recesses to receive the clutches.
long as the clutches are in the recesses the drum revolves with its axis, but
when a lever is introduced with an incline thereon, by which tho drum is
raised and rests on a projecting surface on the lever, the motion of the drum
will be stopped, whilst its axis will continue to rotate, and on the removal of
the lever the drum will again rotate.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Samuel Fox in the Great Seal Patent Office on the
19th May 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
Fox, of Deepcar, Sheffield, send greeting.
WHEREAS er most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of November, in the year of our
Lord One thousand eight hundred and fifty-six, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Samuel Fox, Her special licence that I, the said Samuel Fox,
my executors, administrators, and assigns, or such others as I, the said
Samuel Fox, any executors, administrators, and assigns, should at any timo
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 DRAWING WIRE AND TUBES," upon the condition (amongst others) that I,
the said Samuel Fox, my executors or administrators, by an instrument
in writing under my, or their, or one of their bands 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.
NOW KNOW YE, that I, the said Samuel Fox, do hereby declare the
nature of the said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following stato-
ment thereof, that is to say:-
This Invention has for its object improvements in machinery for drawing
wire and tubes. For these purposes, the chain to which the drawing plyers
are attached passes under a guide pulley, and then ascends and is made fast

page_text: to a pulley on an axis above, and its end is fixed to such pulley. The axis on
which the pulley is placed receives a constant rotatory motion from any suit-
able power, which gives motion also to the drum on which the wire is wound.
The pulley is at times locked to the axis by projections or clutches, which,
when the pulley has made a complete revolution, are withdrawn by inclines on
the face of the pulley, and the workman may stop the revolution of the pulley,
before it completes a revolution, by means of a lever catch, the end of which,
when desired, is made to enter a hole in a collar with inclines, which is also
on the axis, and towards which the pulley is constantly pressed by a spring,
and such collar is arranged to be connected to a fixed collar on the axis. The
drums on which the wire is wound are driven in the ordinary manner, but
apparatus is applied in order to stop their rotation with greater convenience.
On the axis of a drum a collar is affixed, having on it inclines and clutches,
and the boss is formed with recesses to receive the clutches; so long as the
clutches are in the recesses the drum revolves with its axis, but when a lever
is introduced with an incline thereon, by which the drum is raised and rests on
a projecting surface on the lever, and the motion of the drum will be stopped,
whilst its axis will continue to rotate, and on the removal of the lever the
drum will again rotate.
And in order that my Invention may be most fully understood and readily
carried into effect, I will proceed to describe the Drawing hereunto annexed.
DESCRIPTION OF THE DRAWING.
Figure 1 shows a side elevation, and Figure 2 a plan, of a machine for
drawing wire or tubes constructed according to my Invention. a, a, are chains,
to which the drawing plyers are attached. The machine is arranged with two
sets of plyers, draw plates, and drums or blocks; and to avoid complication I
will describe the action of one pair of plyers and apparatus connected there-
with. The chain a to which the plyers are attached, passes under the guide
pulley b, ascends and is made fast to the periphery of the pulley c, which is
free to revolve on the axis d when disengaged from a projection or key on the
axis. The axis d receives motion by means of the tooth wheel d* taking into
the teeth of the intermediate tooth wheel e, which receives motion from the
tooth wheel f¹ fixed on the main driving shaft f, as clearly shewn by the
Drawing. is a collar (loose on the axis d), formed with inclines thereon,
which correspond with inclines formed on the face of the pulley c, and the
collar d' may be held in a fixed position when desired by the lever g, one end
of which is formed with a projection to enter holes formed on the collar d³.
The pulley c has a slot formed in its face, into which a projection on the

page_text: collar enters. The action of the apparatus is as follows:-When a draw
of the pliars is required to tako place, the workman moves the plyers up to
the draw plate, by which the pulley c will rotato backwards into a position to
engage its inclines with the inclines on the collar d', the spring d** acting to
press the pulley into position, thus causing it to engage with the collar, and
also with the fixed projection on the axis d, by which the pulley will be caused
to rotate and give motion to the chain and its plyers, the projection on the
lever g being retained out of action by the workman whilst the draw takes
place; but when the action of the plyers is to be arrested, either before or at
the end of the draw, the workman causes the projection on the lever g to enter
one of the holes on the collar d', by which its revolution will be arrested, and
the inclines upon it will act on the inclines on the face of the pulley c, and
thus throw it out of action, and it will be retained out of action until the parts
aro again placed in position for another draw by the workman.
Tho Drawings also show the method in which the drum is driven, in order that
it may be thrown off with greater facility when necessary. m is a vertical axis,
driven by spur wheels, as shown; on the top of the axis m is a disc or plato n,
in which are two holes. o is the drum, which is capable of turning freely on
the upper end of the axis m, and has on its under side two projections o¹, o',
and these when the drum is in gear fall into the holes in the disc n, and so
the drum is driven. There aro also on the under side of the drum o, but
exterior of the projections o', o', two inclines 0, 0, which serve to lift tho
projections o', o', out of the holes in the disc, and so to throw the drum out of
gear; for this purpose the lover p is used. This lever has a point p' on its
side, which enters under one of the inclines o, and as the drum revolves it
rides up on it and raises the drum. When the drum is out of gear the lever p
enters further under the drum, so that it comes under a flange exterior of the
inclines, and thus the drum is prevented from descending when the top of the
incline is past.
In witness whereof, I, the said Samuel Fox, have hereunto set my
hand and seal, this Nineteenth day of May, in the year of our Lord
One thousand eight hundred and fifty-seven.
