IMPROVEMENTS IN MACHINERY OR APPARATUS FOR DRAWING WIRE
Year: 1853

page_text: LETTERS PATENT to Richard Johnson, of Manchester, in the
County of Lancaster, Wire Drawer, for the Invention of "Im-
Sealed the 20th October 1853, and dated the 23rd April 1853.
5 Wire Drawer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR DRAWING WIRE" to be
as follows:
My improvements relate to a method of drawing that portion of the
wire through the dies which is required for attachment to the drum
upon
which it is to be wound, and consist in the application of a second
drum situate horizontally upon the bench; this drum is provided with
a chain and clamp for grasping the end of the wire, and has rotatory
motion communicated to it at pleasure, by means of suitable gearing,
and at a slower rate than that of the usual winding-on drum. The

page_text: wire end being attached to the clamp, the wheel work is put into gear,
so as to cause the drum to revolve, and draw forward a certain length
of material; but this having been done, the apparatus, by a self-acting
arrangement, becomes disengaged from the driving power. The end
thus drawn forward may then be attached to the usually employed
drum, and the operation of drawing conducted in the ordinary manner.
filed by the said Richard Johnson, in the Great Seal Patent Office,
on the 21st October 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
RICHARD JOHNSON, of Manchester, in the County of Lancaster, Wire
Drawer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of April, in the
year of our Lord One thousand eight hundred and fifty-three, in the
sixteenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Richard Johnson, Her especial licence
that I, the said Richard Johnson, my executors; administrators, and
assigns, or such others as I, the said Richard Jolinson, 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 OR APPARATUS FOR DRAWING WIRE," upon the condition,
amongst others, that I, the said Richard Johnson, by an instrument
in writing under my hand and seal, should particularly describe and
ascertain the nature of the said Invention, and in what manner the
saine 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..

page_text: NOW KNOW YE, that I, the said Richard Johnson, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement and accompanying drawing (that is to say):
My improvements relate to a method of drawing that portion of the
wire through the dies which is required for attachment to the drum
upon which it is to be wound, and consists in the application of a
second drum, situate horizontally upon the bench. This drum is pro-
vided with a chain and clamp for grasping the end of the wire, and
has-rotary motion communicated to it at pleasure by means of suitable
gearing, and at a slower rate than that of the usual winding-on drum.
And in order that my Invention may be fully understood, I have
appended to this my Specification an illustrative drawing, which I will
now proceed to describe. Figure 1, is a partial side view of a drawing
bench; and Fig. 2; is a vertical section of the same. The usual wind-
ing on drum is shewn at a, mounted upon a shaft b, which is caused
to revolve by the line shaft c. Upon the shaft b, is mounted loosely
the drum d, which constitutes my improvement, resting upon the
brass e, of the shaft pedestal, and upon which it may therefore revolve,
independently of the drum a. Upon the shaft b, is also mounted
loosely a pinion f, running upon a collar g, by which it is kept up-
ward; this pinion is placed in gear with another 1, affixed to a shaft i,
which, through the intervention of pinions j, and k, drives the drum d,
by means of internal teeth. The boss of the pinion f, is surrounded
by a friction hoop'l, which is formed in two parts, drawn together by
bolts, so as to gain sufficient hold for causing the gearing to revolve;
and-it is provided at its under part, with projections m, of which there
are four in the circumference. Beneath there is situate a clutch n,
-with similar projections, which clutch is free to slide upon the shaft 6,
but it is caused to revolve therewith by means of a feather. To the
clutch n, is adapted a fork o, turning upon an axis.p, from which there
Lextends a lever, the end thereof being connected to a rod 1, passing
through a guide plate at bottom. The rod, is furnished with a
projecting parts, and on the other side is connected to a lever t, turn-

page_text: ing upon a fixed centre. To the drum d, is attached a chain u, pro-
vided at its other end with à clamp v. When it is desired to draw
forward the required length of wire, this clamp is caused to grasp a
portion which has been passed through the die; the. attendant then
places his foot upon the projections, of the rod 7, by which means the
lever, will be depressed so as to turn the axis p, upon its centre,
thereby raising the clutch n. and causing the pinion f, to revolve
thro' the intervention of the friction hoop, which revolution will
impart a slow rotatory motion. to the drum d, by means of the gearing
before described, whereby the chain u, will become coiled upon its
periphery, and the clamp'v, will draw the wire through the die. When
a sufficient length has been obtained, the attendant, by removing his
foot from the projection, will allow the clutch n, to fall, and the motion
of the drum d, will be arrested. In order, however, to ensure the dis-
engagement from the driving power, I adapt the lever t, the outward
end of which being depressed, will cause the axis p, to turn upon its
centre, so as to carry the clutch n, downward. The end, it will be
observed, is thus drawn through the die by one attachment only of the
clamp, and it is therefore free from those numerous indentations which
are consequent upon the ordinary method of operation; and as the
power exerted is continuous and uniform, the material is not submitted
to those sudden strains by which it is so frequently broken. And, as a
further precaution against breakage, I adapt the friction hoop 1, before
mentioned, as a medium for communicating the power; for, should an
excessive resistance take place, the said hoop will slip around the boss
of the pinion f, and the drum d, will remain stationary. The arrange-
ment of gearing I have shewn is calculated to effect a slower revolu-
tion of the drum d, than that of the ordinary drum a, and this speed
may be modified as thought desirable. The end of wire having been
drawn as above described, it is to be attached in the usual manner to
the drum a, and wound thereon, as commonly practised.
Having thus described and ascertained the nature of my said Inven-
tion, and the manner in which the same is to be performed, I desire it
to be understood that I claim, as secured to me under the above in

page_text: part recited Letters Patent, the application of a second horizontal drum
carrying suitable apparatus for drawing the wire for the purpose above
set forth.
In witness whereof, I, the said Richard Johnson, have hereunto
set my hand and seal, this Twentieth day of October, One
thousand eight hundred and fifty-three.
