Year: 1868

page_text: LETTERS PATENT to Thomas Wrigley, of Manchester, in the County
of Lancaster, Mechanical Engineer, and Joseph Holding, of
Wheelton, near Chorley, in the same County for the Invention of
"CERTAIN IMPROVEMENTS IN LOOMS FOR W
PROVISIONAL SPECIFICATION left by the said Thomas Wrigley and
Joseph Holding at the Office of the Commissioners of Patents, with
their Petition, on the 22nd August 1868.
WC, THOMAS WRIGLEY, of Manchester, in the County of Lancaster,
Mechanical Engineer, and JOSEPH HOLDING, of Wheclton, near Chorley,
in the same County, do hereby declare the nature of the said Invention
for "CERTAIN IMPROVEMENTS IN LOOMS FOR WEAVING," to be as follows:-
Our Invention is designed, first, for the purpose of making the healds
or harness employed in looms for weaving more durable than hitherto ;
and, secondly, for effecting improvements in the "temples" of looms that
will retain and keep the traverse tension of the cloth across the selvedges
uniformly distended throughout the piece.

page_text: The improvements relate, first, to the healds employed for shedding,
and more particularly to that class of healds which are constructed by
knitting the top of fine metal and the bottom of yarn, or vice versa.
According to the first part of our improvements the stave of the heald
around which the yarn portion of the heald is secured is constructed in a
round, square, or other suitable shape that will admit of its being turned
or altered in position, which effects (by reason of the heald yarn at the
lower end being attached thereto) at such times a slight shift or removal
of the heald yarns passing through the metal or yarn eye of the heald,
thereby removing the wearing surfaces in contact with the eye over
a surface equal to an amount that the stave is capable of being
reversed to.
According to the second part of our improvements we employ but
one roller, formed of wood or other suitable material, from which small
teeth or points project in a slanting direction, the said roller being
mounted on a fixed or ridged axle; the cap of the temple being secured
by an overlap or projecting ear can be readily adjusted by set screws or
other equivalent to a position that will regulate any required bearing or
pressure upon the cloth relative to the temple roller.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 2
filed by the said Thomas Wrigley and Joseph Holding in the Great
Seal Patent Office on the 22nd February 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
WRIGLEY, of Manchester, in the County of Lancaster, Mechanical
Engineer, and JOSEPH HOLDING, of Wheelton, near Chorley, in the same ?
County, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of August, in the year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Thomas Wrigley and Joseph Holding, Her
special license that we, the said Thomas Wrigley and Joseph Holding,
our executors, administrators, and assigns, or such others as we, the
said Thomas Wrigley and Joseph Holding, our executors, administrators,

page_text: 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 "CERTAIN IMPROVEMENTS IN LOOMS
FOR WEAVING," upon the condition (amongst others) that we, the said
Thomas Wrigley and Joseph Holding, our executors or administrators,
by an instrument in writing under our, or their, or one of their hands
and seals, 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 I, the said Joseph Holding, 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:-
These improvements relate to parts of the loom well known, the first
being the "healds," in which various modifications are shewn, and
which are designed to make the heald more lasting; and, secondly, the
improvements relate to the temple; and are designed for the purpose of
retaining the traverse tension of the cloth whilst weaving with a more
certain and uniform tenacity.
The first part of these improvements relating to the "healds" consist
in knitting the healds in the ordinary manner, the material of which
they are knit being composed of fine wire and yarn, that is the top
being composed of wire and the bottom of yarn, or vice versa.
T
A further improvement in the healds consists in making the bottom
or top heald stave or both of them square or other suitable form, to one
side of which the knitted portion of the heald is secured; for instance,
suppose the bottom "heald stave" be square and the heald yarn passing
through the eye be secured to one side of such stave, the whole length
or bottom portion of the heald yarn by being turned will simultaneously
alter the position of the heald yarns to another wearing point. In cases
where metal eyes or "males are used, or any eye through which the
yarn may pass, these moveable staves can be applied with great
advantage to both top and bottom.
"

page_text: The second part of these improvements relating to the temple is
designed more particularly to that class of "temple" in which wood
rollers and metal pins are employed, and the improvements consist, first,
in using but one roller of larger diameter than usual, the periphery of
which is provided with metal pins for holding the cloth. The roller
forms a loose boss which as the cloth passes over it freely revolves upon
a fixed pin retained in the box or under portion of the temple; the cap
of the temple being formed adjustable is so arranged that it can be
lowered so as to cause the cloth to press well upon and nearly embrace
the upper half of the loose boss, or it may be raised and secured so as
only slightly to press thereupon.
In order that the Invention may be better understood and explained
in detail we have hereunto attached a Sheet of Drawings made about
full size, similar parts having corresponding letters.

Figure 1 represents the ordinary class of worsted heald now employed
for weaving calicoes, and Figure 2 represents a front elevation of the same.
In these Figures (see "a") is the heald yarn, the top portion of which con-
taining the eye is secured to the top ordinary heald stave (b); the bottom
yarn looped through the eye passes under the moveable stave "c"
to one side of which it is secured, thus we will suppose warp has
passed the heald, when in the position shewn in full lines the twister
for the next warp will give the heald stave a quarter of a turn, which
will simultaneously more the wearing parts of the bottom yarns in the
eyes so as to present a new wearing surface for the next warp, by
this means the present knitted healds will be rendered much more
durable.
Figures 3 and 4 represent similar views to the last of healds in which
metal or "male" eyes, or any eyes through which the yarn may pass,
are used; in this class of heald both top and bottom staves can be turned
for the purpose of removing the yarn loop passing through the metal or
other eye.
Figures 5, 6, 7, 8, 9, and 10 relate to the improved temple. Figure 5
represents the "temple" in elevation with the lid secured down in its
place; Figure 6 represents a plan view of the temple secured to the temple
bar; Figure 7 represents a transverse section of the temple box and loose
boss roller; Figure 8 represents a plan view of the temple having the cop
removed; Figure 9 represents an outside end view shewing the adjustable
and tightening screw; and Figure 10 represents a longitudinal section of

page_text: the loose boss roller. In these Figures "d" is the lower box of the temple
secured to the top sample bar "e." In this box the pin upon which the
loose boss "f" revolves is supported and prevented revolving by reason
of the square end shewn at "g." H is the cap of the temple which
is provided with the overlap lip "i" which embraces the end of the
temple K upon which it can be raised or lowered for adjustment of
pressure on the cloth; after which it is tightened or secured in its position
by the screw m.
Having now described the nature of our said Invention, together with
the method of carrying the same into practical effect, we wish it to be
distinctly understood in conclusion that we claim,-
First. The novel employment and use of the combination of metal and
yarn for composing healds for weaving, as herein-before described.
And, secondly. We claim the novel employment, use, and adaptation
to ordinary worsted healds or healds supplied with metal or "male"
eyes, or any eyes through which the yarn may pass, of square or other
shaped staves to be employed for removing the wearing parts of the yarn
so as to make such healds more durable, as herein-before described and
set forth.
And, lastly. We claim the general construction of the one boss roller
temple together with the several parts connected therewith, or any
slight modification thereof, as herein-before described and fully set forth
and fully illustrated in the Drawings attached.
In witness whereof, I, Joseph Holding, have hereunto set my hand
and seal, this Twentieth day of February, in the year of our
Lord One thousand eight hundred and sixty-nine.
