IMPROVEMENTS IN WIRE HEALDS AND HARNESSES, AND IN HEALD SHAFTS
Year: 1878

page_text: LETTERS PATENT to Henry Bernoulli Barlow, junior, of Manchester, in the
County of Lancaster, Manufacturer of Patent Wire Healds, for the Invention
of "IMPROVEMENTS IN WIRE HEALDS AND HARNESSES, AND IN HEALD
SHAFTS."
Sealed the 22nd November 1878, and dated the 24th June 1878.
PROVISIONAL SPECIFICATION left by the said Henry Bernoulli Barlow at
the Office of the Commissioners of Patents on the 24th June 1878.
HENRY BERNOULLI BARLOW, junior, of Manchester, in the County of Lancaster,
Manufacturer of Patent Wire Healds. "IMPROVEMENTS IN WIRE HEALDS AND
HARNESSES, AND IN HEALD SHAFTS."
This Invention consists in certain improvements in wire healds and harnesses,
also in the shafts or frames for carrying the healds.
The first part of my Invention relates to the healds which have commonly been
made of one piece of wire, as described in the Specification of Letters Patent granted
to Darius Chase Brown on the 9th day of September 1867, No. 2551.
The wire forming the heald is twisted together at one end, and at the other end
is a loop; now my Invention consists in making a similar twist at each end of the
heald.
Another part of my Invention consists in making a wire heald or mail for
jacquard or other harness of a single wire doubled only in the middle to form the
warp eye, and if necessary at one or both ends. The wire may be round or of other
section.

My improvements in the heald shafts relate to shafts made with metal ends for
connecting the top and bottom staves together. The rods supporting the healds
may be flat, round, or of other section. It is customary to use books and nuts at
one or both ends for tightening the metal rods on which the wire healds are
threaded to facilitate adding to or taking from the number of healds on the shafts.
Instead of the hooks and nuts above referred to I pass the metal rods through slots
made in the metal ends, and use split pins, cotters, or other equivalents, at one or
Price &31

split pins keeps the rods tight.
Another part of my Invention consists in rivetting the metal rods at both ends
of the heald shafts to economise space, so that the full width of the reed space of
the loom may be filled with warp.
Washers may be placed between the rivetted ends of the metal rods and the ends
of the shafts, so that the rods may be taken out and re-rivetted several times by
removing the washers.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said Henry Bernoulli Barlow in the Great Seal Patent Office on the 24th 1
December 1878.
HENRY BERNOULLI BARLOW, junior, of Manchester, in the County of Lancaster,
Manufacturer of Patent Wire Healds. "IMPROVEMENTS IN WIRE HEALDS AND
HARNESSES, AND IN HEALD SHAFTS."
This Invention consists in certain improvements in wire healds and harnesses,
also in the shafts or fraines for carrying the healds.
The first part of my Invention relates to the healds which have commonly been
made of one piece of wire, as described in the Specification of Letters Patent granted
to Darius Chase Brown on the 9th day of September 1867, No. 2551.
The wire forming the heald, according to the Specification above referred to, is
twisted together at one end, and at the other end is a loop, as shewn in Fig. 1 of
the accompanying Sheet of Drawings; now my Invention consists in making a
similar but longer twist at each end of the heald, as shewn in Fig. 2; by this
means the locking of the healds on the metal rods is prevented.
Another part of my Invention consists in making a wire heald or mail for.
jacquard or other harness of a single wire doubled or looped in the middle to form
the warp eye, and pressed to make it smooth, as shewn in Figs. 3 and 4, and if
necessary, at one or both ends. The jacquard mail shewn in Fig. 4 to be prolonged
through the cumber board and the lingoe is hooked to the other end. The wire
may be round or of other section, and of any suitable metal.
My improvements in the heald shafts relate to shafts made with metal ends for
connecting the top and bottom staves together, as shewn in Figs. 5 and 6, Fig. 5
being a front view, and Fig. 6 an end view of the same.
In these views a, a, are the usual wood staves or shafts; b, b, are metal rods on
which the wire healds are threaded or strung; d, d, are the inetal ends of the shafts,
with slots or holes d', d, punched or drilled, through which the metal rods b, b,
pass, and are secured by the split or cotter pins e, c. These split pins are easily
taken out when required to release the rods b, b, and when ready the pins can be
put in again. This fastening overcomes the objections to hooks and nuts which
cannot be made to stand the jarring and vibration to which all loom harness iş

subject. Much damage is caused if the nuts shake loose and come off.
siderable space in the healds is also saved by the use of split pins in place of hooks
and nuts.
Figs. 7 and 8 represent a front and end view of one of my heald shafts in which
the metal rods b, b, are rivetted through the metal ends d, d, to utilise all tho
available space for the warp; with this shaft the full reed space of the loom can
be used.
Washers ff, may be placed at the ends of the rods b, b, if desired, to enable the
rivetted ends to be filed off and re-rivetted after removing a washer. The rods may
also be re-rivetted without the use of washers.
Having thus stated the nature of my Invention, and described the manner of
performing the same, I declare that I claim,-
First. Making wire healds in the manner described in the Patent of Darius
Chase Brown above referred to, but with a long twist at each end for the purpose
set forth.
Secondly. Making wire healds or wire jacquard mails of single wire, doubled,
twisted, or looped, for the warp eye, and also, if necessary, at one or both ends.
Thirdly. Making a heald shaft with metal ends, through which the rods pass,
and which are secured with split pins, cotters, or other equivalents in place of hooks
and nuts at one or both ends; the said split pins or cotters may be used with shafts
having ends of wood other material.
And, Lastly. Rivetting the metal rods at both ends into the metal ends of the
shafts, either with or without using washers.
In witness whereof, I, the said Henry Bernoulli Barlow, junior, have
hereunto set my hand and seal, this Twenty-first day of December, One
thousand eight hundred and seventy-eight.
