Year: 1883

page_text: LETTERS PATENT to Joseph William Hirst, James Hirst and James Bottomley,
Trading under the style or firm of Bottomley and Hirsts of Brighouse in the
County of York, Wire Manufacturers for an Invention of " IMPROVED
APPARATUS FOR ROLLING ANGULAR WIRE, AND IN MACHINES. FOR GROOVING
PROVISIONAL SPECIFICATION left by the said Joseph William Hirst, James
Hirst, and James Bottomley at the Office of the Commissioners of Patents on
the 21st March 1883.
JOSEPH WILLIAM HIRST, JAMES HIRST, and JAMES BOTTOMLEY Trading under
the style or firm of Bottomley and Hirsts of. Brighouse in the County of York,
Wire Manufacturers "IMPROVED APPARATUS FOR ROLLING ANGULAR WIRE, AND
IN MACHINES FOR GROOVING ROLLERS EMPLOYED THEREIN
"
Our Invention has for its purpose the making (throughout the whole of its
length) of three cornered or other form of angular wire for card making
purposes.
The form of apparatus we employ consists in a pair of rollers mounted in
suitable framework and caused to revolve by gearing. On the periphery of
each roller, and exactly opposite each other, we grind, cut or otherwise form an
angular groove which when put together leaves a space or opening forming two
angles twice the size of one wire. Two wires are then fed between the rollers,
(through the angular space) and are squeezed whilst passing between the rollers
into the required angular form, and wound upon winders By this means two
wires are operated upon at the same time.
In some cases a groove is cut in one roller only, the upper roller being plain,
but by this means only one length of wire is operated upon. The rollers are made
sufficiently wide as to enable us to cut several grooves therein, so that different
thicknesses of wire may be operated upon by the same machine.

page_text: The machine or apparatus we employ for grinding or cutting the grooves in the
above named rollers consists in the employment of a convenient length of copper
wire (or other material) held fast at each end and made to spin or revolve by
suitable gearing, supported by light framework which can be readily attached to
the wire rolling machine,
As it is requisite for the angular grooves in the rollers to be cut exactly opposite
each other, we prefer to do this whilst the rollers are in their own pedestals; for
this purpose the apparatus having the copper wire is attached to the first
mentioned machine and so placed that the copper wire is in contact with both
rollers at the same time.
The rollers are then made to revolve against the copper wire which is spinning
around in an opposite direction to the rollers, and a groove is thereby ground or
cut therein. The grooves formed in the rollers become taper by the wire wearing
smaller as it is grinding the groove so that the further the wire enters, the finer
the angle becomes.

the said Joseph William Hirst, James Hirst, and James Bottomley in the
Great Seal Patent Office on the 21st September 1883.
JOSEPH WILLIAM HIRST, JAMES HIRST and JAMES BOTTOMLEY Trading under
the style or firm of Bottomley and Hirsts of Brighouse in the County of York-
Wire Manufacturers "IMPROVED APPARATUS FOR ROLLING ANGULAR WIRE, AND
IN MACHINES FOR GROOVING ROLLERS EMPLOYED THEREIN "
Our Invention has for its purpose the making (throughout the whole of its
length) of three cornered or other form of angular wire for card making purposes.
The form of apparatus we employ consists in a pair of rollers mounted in
suitable framework and caused to revolve by gearing. On the periphery of each
roller, and exactly opposite each other, we grind, cut or otherwise form an angular
groove, which, when the two rollers are put together leaves a space or opening
forming two angles, twice the size of one wire. Two wires are then fed between
the rollers (through the angular space) and are squeezed whilst passing between
the rollers into the required angular form, and wound upon winders. By this
means two wires are operated upon at the same time.
:
In order that this part of our Invention may be better understood we herein
give reference to the accompanying sheets of Drawings wherein Fig 1 is front
elevation of one side of the machine, and Fig 2 is end view thereof. 1 represents
framing of said machine and 2. main driving shaft, supported by adjustable
pedestals 3. The grooved rollers for forming the angular wire are shewn at 4
and 5, the lower one receiving its rotary motion from the main driving shaft by
spur wheels 6 and 7 whilst the upper one its rotary motion from spur wheels 8
and 9. The wire intended to be, rolled and formed angular is first placed upon the
winders 10 and 11 from which it is taken and passed through the guide 12, thence
between the rollers 4 and 5 and wound onto other winders 14 and 15 the said
grooved rollers squeezing or rolling the wire into the required shape as it travels
along. Screws 16 and 17 are employed for adjusting the rollers which may be of
any suitable diameter or width so as to enable us to cut several grooves therein
of different sizes whereby various sizes of wire may be operated upon by the same
machine-The winders 14 and 15 receive their motion from pullies and straps
18, 19 and 20, or other convenient arrangements of driving may be employed as
will be well understood.
The grooved rollers are shewn on a larger scale at Fig 3.
The machine or apparatus we employ for grinding or cutting the grooves in the
above named rollers consists in the employment of a convenient length of copper
wire (or other material) held fast at each end and made to spin or revolve by
suitable gearing, supported by light framework, which can be readily attached to
the wire rolling machine.
As it is requisite for the angular grooves in the rollers to be cut exactly opposite
each other, we prefer to do this whilst the rollers are in their own pedestals; for
this purpose the apparatus having the copper wire is attached to the first mentioned
machine and so placed that the copper wire is in contact with both rollers at the
same time. The rollers are then made to revolve against the copper wire which is
spinning around in an opposite direction to the rollers, and a groove is thereby
ground or cut therein. The grooves formed in the rollers become taper by the
wire wearing smaller as it is grinding the groove so that the further the wire enters,
the finer the angle becomes.
This part of our Invention is shewn in Fig 4 which is elevation of the apparatus
for holding and revolving the copper wire.

page_text: This apparatus is portable and can be readily attached and detached to the
framework supporting the grooved rollers. We have shewn the apparatus attached
to the rolling machine with the wire in contact with the rollers as will be seen on
reference to the Drawings-21 being the wire which is held at each end by
holders 22 forming part of or being connected to short spindles 23 and 24 caused
to revolve by straps 25 from upright shaft 26 which receives its motion from
bevil wheels 27 and shaft 28 the said shaft being driven by other beviled wheels 29
which may be driven either by pulley or hand wheel as found most convenient.
It will be seen that as the vertical copper wire is spinning in one direction and in
contact with the rollers 4 and 5 which are revolving in another or opposite
direction, that a groove will be cut in both rollers and that such grooves will
become taper or angular in consequence of the wire wearing smaller whilst
grinding the grooves, in which case it will be evident that the angle cut in the
rollers will become finer, the further the wire enters therein. The framework 30
supporting the wire is pushed nearer the rollers by means of hand wheel 31 and
screw 32 the parts being dovetailed for that purpose so that the pressure of the
wire against the rollers can be regulated as required.
Having now fully described our Invention, and shewn by Drawings how the
same is to be performed or carried into practice, we would have it understood that
we do not confine ourselves to the exact details herein shewn and described, as
they may be somewhat varied without departing from the essential features thereof,
but what we consider new and therefore claim as our Invention is-
Firstly. The employment of grooved rollers for making two continuous lengths
of angular wire in manner substantially as herein shewn and described.
Secondly. The employment of apparatus such as is herein shewn and described
for grooving rollers.
In witness whereof I the said James Bottomley for and on behalf of myself
and the said Joseph William Hirst and James Hirst, have hereunto set my hand
and seal this nineteenth day of September in the year of our Lord, One thousand
hundred and eighty three.
