PROVISIONAL SPECIFICATION left by the said James Gabbott at the
Office of the Commissioners of Patents, with his Petition, on the
27th June 1867.
I, JAMES GABBOTT, of Blackburn, in the County of Lancaster, Commission
Agent, do hereby declare the nature of the said Invention for "IMPROVED
MACHINERY OR APPARATUS TO BE EMPLOYED IN THE MANUFACTURE OF WIRE HEALDS
FOR LOOMS FOR WEAVING," to: be as follows:-
In the construction of wire healds for looms for weaving I prefer to use
brass or copper wire which is placed on a creel, and from thence wound on
bobbins, the bobbins are then placed on spindles attached to the arms or rim
of a wheel, through holes in which the end of each wire is passed and received
by a pair of draw rollers covered; with flannel or other soft material so as not.
to damage the wire. On motion being imparted to the wheel carrying the-
bobbins and wire such wire is twisted or," doubled" together. A length of wire
equal to half the length of, the heald having been drawn forwards and doubled a.
bell actuated from the wheel above mentioned calls the attention of the

page_text: operative, who inserts (between the wires at the point they come in contact
with each other) a wire of larger diameter, which on being withdrawn on the
completion of the heald forms the eye thereof. A knife cuts off the length of
twisted or doubled wire, the eye in the centre of which is then placed a pin,
and each end of such wire is received in the end of a hollow shaft through
which is a hole and pin, each end is wrapped round the said pin, and on motion
being imparted to the shaft and pins the ends are wound thereon forming
a loop at each end of the heald, and afterwards a hollow tube of metal answering
the purpose of the ordinary heald staves is passed through the loops; they are
then complete. The apparatus. above described is equally applicable for
doubling wire and twine or cord from which to manufacture healds or for other
purposes.
In the description herein contained I describe one wheel and set of
bobbins, but such may be arranged to construct two or more heald wires at
one time and operation by the use of additional wheels and bobbins.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Gabbott in the Great Seal Patent Office on the
24th December 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
GABBOTT, of Blackburn, in the County of Lancaster, Commission Agent, send

Letters Patent.
:
NOW KNOW YE, that I, the said James Gabbott, do hereby declare
the nature of my 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:-
In the construction of wire healds for looms for weaving I prefer to use.
brass or copper wire which is placed on a creel, from thence wound on.
bobbins, the bobbins are then placed on spindles attached to the arms or rim
of a wheel through holes in which the end of wire is passed and received by
a pair of draw rollers covered with flannel or other soft material so as not to
damage the wire. On motion being imparted to the wheel carrying the
bobbins and wire such wire is twisted or "doubled" together. A length of
wire equal to the length of the heald having been drawn forwards and doubled,
a bell actuated from the wheel above mentioned calls the attention of the
operative who inserts (between the wires at the point they come in contact.
with each other) a wire of larger diameter, which on being withdrawn on the
completion of the healds forms the eye thereof. The length of twisted or
doubled wire is cut, and the eye in the centre of which is then placed a
pin, and each end of such wire is received in the end of a hollow shaft. through.
which is a hole and piu; each end is wrapped round the said pin, and on
motion being imparted to the shafts and wire the ends are wound thereon forming
a loop at each end of the heald, and afterwards a hollow tube. of metal
answering the purpose of the ordinary heald staves is passed through the loops ;
they are then complete. The apparatus above described is equally applicable
for doubling wire and twine or cord from which to manufacture healds or for
other purposes.
In the description herein contained I describe one wheel and set of bobbins,
but such may be arranged to construct two or more heald wires at one time
and operation by the use of additional wheels and bobbins.
Such being the nature and object of my said Invention I will now proceed
to describe the same more fully; and in order that the same may be clearly.
understood I have hereunto annexed two Sheets of Drawings illustrative thereof,
and have marked the same with figures and letters of reference.
Fig. 1 (Sheet 1) is an end elevation of apparatus for doubling and twisting the
beald wires; Fig. 2 is a plan view; Fig. 3 is a front elevation of the same;
Figs. 4 and 5 are enlarged views; Fig. 6 is front elevation of apparatus for

page_text: forming the loops through which the heald staves pass and for stretching the
heald wire; Fig. 7 is a plan view of the same.
At A is shewn the framework, to the cross rail A¹ of which are fixed a
number of studs B carrying the wheels C, a pair of bobbins D, D, [on which
wire is previously wound by any, ordinary method] are received by the studs or
spindles d, d, the wire from the bobbins, being passed through holes in the rim
of the wheel C is doubled. and, twisted by the revolving action of the wheels C,
which are driven by the wheels E, intermediate wheel F, and carrier wheel F¹,
actuated by means of the shaft, fly wheel, and handle G. As the wires are
doubled; and twisted they are received by the draw, rollers H, H¹, the roller H
-being covered with flannel or other soft material; on a signal by the bell Ja
stout wire K is passed horizontally between the wires, being doubled and
twisted, and on being withdrawn afterwards the eye of the heald is thus
formed, the wire is then, passed between the draw rollers H,, H', actuated
by, the worm H' and worm wheel H³ and around the roller H*; this
latter roller is of diameter equal to the length of wire required for the
construction of each heald, and has a traversing motion imparted thereto by
means of the chased or screwed shaft, M so, as to, prevent one coil of wire.
being upon another; the wire is then cut by shears or a knife passed, along
the groove M¹ dividing the wire into a number of equal lengths, having an
eye in the middle of each length; the loops are formed at each end, and the
wires stretched. by the apparatus shewn at Fig. 6.;, the pin O receives the
eye formed in the wire P, and each end is carried around the pin R, which
is passed through the shaft, or spindle S on rotary motion being imparted
thereto by means of the wheels T, T₁; the end of the wire P forms the loops
for the heald stave; the pin R is, withdrawn, and the completed wire removed;
the form of loops may be varied according to the form of heald stave by the
use of various shaped pins R...
At W, Fig. 2, I have shewn method of doubling wire and twine or cord
from which to manufacture healds or for other purposes; this I effect by passing
twine or cord from the bobbin w through a hole in the stud; the wire is doubled
or twisted thereon as shewn in the Drawings....
Having thus fully. described the nature and particulars of this my said
Invention, together with the manner in which the same is to be or may be
performed or carried into practical effect, I would have it distinctly understood
that I claim,
Firstly, the general. construction and, arrangement of the apparatus for
doubling and twisting and forming the eye in the wire as shewn in the
Drawings.

page_text: Secondly, I claim the use and employment of the grooved roller H2 for
measuring and on which to cut the wires; as shewn in the Drawings and herein.
fully described.
Lastly, I claim the apparatus for forming the loops for the heald staves
and for stretching the wire, as shewn in the Drawings and above fully
described.
In witness whereof I, the said James Gabbott, have hereunto set
my hand and seal, this Twelfth day of December, in the year of our
Lord One thousand eight hundred and sixty-seven.
