Year: 1863

page_text: LETTERS PATENT to Richard Johnson, of Manchester, in the County
of Lancaster, Iron and Wire Manufacturer, and George Bedson, of the
same Place, Manager, for the Invention of "IMPROVEMENTS IN POINTING
WIRE RODS OR WIRE IN ORDER TO FACILITATE THEIR INTRODUCTION INTO DRAW
PLATES."
Sealed the 23rd February 1864, and dated the 26th August 1863.
PROVISIONAL SPECIFICATION left by the said Richard Johnson and
George Bedson at the Office of the Commissioners of Patents, with their
Petition, on the 26th August 1863.
We, RICHARD JOHNSON, of Manchester, in the County of Lancaster, Iron
and Wire Manufacturer, and GEORGE BEDSON, of the same Place, Manager,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
POINTING WIRE RODS OR WIRE IN ORDER TO FACILITATE THEIR INTRODUCTION INTO
DRAW PLATES," to be as follows:-
According to the usual method of pointing wire rods or wire an end is
heated after the coil is made, and has consequently cooled, and this end is
then hammered out into the desired form. By our Invention we effect the
said pointing while the metal is in the heated state imparted for the purpose
of rolling, and consequently before it is wound into the coil.
One method we adopt in carrying out our Invention consists in the employ-
ment of a pair of jaws, into which the attendant places the end to be pointed;
these jaws have a backward and forward motion, and by the former of these

taper end upon the length of rod or wire, it being prevented from passing
onward bodily by the tongs which the attendant uses abutting against a fixed
piece.
Another method consists in feeding the end of the rod or wire to a pair of
revolving conical rollers, which acting upon the metal by their increasing
diameters, form the desired conical end. Or instead of these conical rollers
we employ a roller furnished with a V-groove, within which is a part of corre-
sponding form; between these surfaces the end of the rod or wire is placed,
and the revolution of the grooved roller effects the required pointing.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed by
the said Richard Johnson and George Bedson in the Great Seal Patent
Office on the 26th February 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, .we, RICHARD
JOHNSON, of Manchester, in the County of Lancaster, Iron and Wire Manu-
facturer, and GEORGE BEDSON, of the same Place, Manager, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of August, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Richard Johnson and George Bedson, Her special license that
we, the said Richard Johnson and George Bedson, our executors, adminis-
trators, and assigns, or such others as we, the said Richard Johnson and
George Bedson, our 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
POINTING WIRE RODS OR WIRE IN ORDER TO FACILITATE THEIR INTRODUCTION INTO
DRAW PLATES," upon the condition, amongst others, that we, the said Richard
Johnson and George Bedson, by an instrument in writing under our hands
and seals, (or under the band and seal of one of us,) 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 we, the said-Richard Johnson and George Bedson,
do hereby declare the nature of our 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 Drawings (that is to say) :-
According to the usual method of pointing wire rods or wire an end is
beated after the coil is made, and has consequently cooled, and this end is
then hammered into the desired form. By our Invention we effect the said
pointing while the metal is in the heated state imparted for the purpose of
rolling, and consequently before it is wound into the coil.
One method we adopt in carrying out our Invention is shewn at Figs. 1 and 2
of the accompanying Drawings, the former being an elevation, and the latter a
side view. The driving shaft of the apparatus is at a, carrying a pinion which
gears into a wheel upon a shaft b; this shaft bis provided with a crank c,
connected by a rod d to links e, which are jointed at their other ends to a pair of
pincers f, the holding jaws of which are at g, and the said pincers are mounted
upon guide rods h, so as to be capable of sliding bodily thereon. Ati is a pair
of tongs, the jaws of which can be placed when required in a wedge-shaped
groove formed in the stationary framework k. The wire rod or wire having
been rolled, and being still in a heated state, is seised by the attendant between
the jaws of the tongs i, which jaws are then placed in the groove formed in the
framework k, as shewn in the Drawing. This will have caused the wire rod
or wire shewn at to extend into the machine, as shewn by the red colour.
During this operation the crank c will have been at the opposite end of the
stroke to that represented in the Drawing, but by the time the wire rod or
wire has been adjusted as above described, the said crank will have turned so
as to advance the pincers f towards the said rod or wire, and this advance will
have straightened the links e, so as to open the holding jaws g. The crank
still revolving will now again draw the pincers backward, and in so doing
will pull the links e into the position shewn, thus tightening the jaws g upon
the rod or wire, and a further motion backward will exert a drawing force
upon the rod or wire, which being held by the tongs i and unable therefore to
be drawn forward bodily, will cause an end to be detached, leaving a tapered
part suitable for being introduced into draw plates, after which the rod or wire
is wound (if desired) into the usual coil, and the same operation is repeated
for another end. In order that the attendant may not have to resist the pull
by the pincers f, the jaws of the tongs extend beyond the groove in which they
are placed, so as to abut against the frame k, which therefore sustains.
the pull.
Another method we adopt for the purpose of our Invention is shewn at

page_text: Figs. 3 and 4, in which m, m, are a pair of conical rollers caused to revolve
by any suitable means, and between which is placed a fixed bed n. The wire
rod or wire p having been rolled as before mentioned, is held by the attendant
in a pair of tongs o, and the end is thrust forward upon the bed n between the
rollers m.. As this thrusting forward takes place the attendant turns the rod
or wire, and the conical surfaces effect a pointing thereof, as shewn in the
Drawing by the red color. At q is a fixed guide, provided with a slot, through
which the rod. or wire is passed, and acting as a guide for assisting the
attendant when introducing and turning the said rod or wire.
Figs. 5 and 6 shew another method which we adopt. In this instance a
pair of rollers r, r, with conical faces is employed, so as to constitute a V-groove,
These faces are roughed, so as to provide filing or cutting surfaces, and they
are caused to revolve by any convenient means. The wire rod or wire to be
pointed is held by a pair of tongs *, and is then passed through a guide s and
between the rollers », where it becomes tapered by the cutting or rasping
action of the two conica! faces constituting the V-groove.
Having thus described and ascertained the nature of our said Invention,
and the manner of carrying the same into effect, I desire it to be understood
that we claim as secured to us under the above in part recited Letters
Patent,
Firstly, drawing off an end of the wire rod or wire, so as to leave a pointed
part thereon..
And, secondly, the use of rollers for rolling or for rasping or cutting the
said ends into a pointed form.
In witness whereof, I, the said George Benson, have hereunto set my
hand and seal, this Twenty-fifth day of February, in the year of our
Lord One thousand eight hundred and sixty-four.
