IMPROVEMENTS IN 'SELF-ACTING TEMPLES' FOR LOOMS."
Year: 1877

page_text: LETTERS PATENT to John Hardaker, of Leeds, in the County of York, for
the Invention of "IMPROVEMENTS IN 'SELF-ACTING TEMPLES' FOR LOOMS."
PROVISIONAL SPECIFICATION left by the said John Hardaker at the Office
of the Commissioners of Patcuts on the 9th April 1877.
JOHN HARDAKER, of Leeds, in the County of York. "IMPROVEMENTS IN 'SELF-
ACTING TEMPLES' FOR LOOMS."
My Invention relates to improvements in "self-acting temples" for looms, hereto-
fore made on the ring and washer principle, which rings and washers have hitherto
been inounted obliquely side by side on a stud or pin passing through their centres,
having a limited angle or bevel insufficient for some kinds of templing.
The first part of my improvements consists in so arranging and shaping the rings
and supports on which they revolve that they lie side by side at any suitable angle
or bevel, and are made to slide into a socket or carrier made of sheet iron or
any suitable material, and fixed therein by any convenient means, thus dispensing
with the herein-before named stud or pin and obtaining any required angle or
bevel.
The second part of my improvements consists in adapting two or more sets of
rings with fewer of them in each set, in order to " temple" the cloth by gripping
the selvage or edge only.
The third part of my improvements refers to the application of a roller, conical
or otherwise, by preference mounted on the "temple" cover, and provided with a
ratchet movement with suitable levers so arranged as to communicate with any
convenient moving part of the "temple" or loom (my self-acting adjusting apparatus
in combination with "temples," described and claimed in the Specification of the
Patent granted to me the 14th July 1875, No. 2532, is particularly applicable for

page_text: this), by which the aforesaid roller is made to revolve. The roller is provided with
teeth or other rough surface so as to draw the cloth over the ring part, thus enabling
the "temple" to operate near to the "shed."
In connection with the lever arrangement is provided a telescopical compensating
rod, or the lever is made to give so as to adapt it or themselves to the tension of
the cloth during the operation of weaving.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Hardaker in the Great Seal Patent Office on the 8th October
1877.

ACTING TEMPLES FOR LOOMS."
"IMPROVEMENTS IN SELF-
My Invention relates to improvements in "self-acting temples" for looms, hereto-
fore made on the ring and washer principle, which rings and washers have hitherto
been mounted obliquely side by side on a stud or pin passing through their centres
having a limited angle or bevil insufficient for some kinds of templing.
The first part of my improvements consists in so arranging and shaping the rings
and supports on which they revolve that they lie side by side at any suitable angle
or bevel, and are made to slide into a socket or carrier made of sheet iron or
any suitable material and fixed therein by any convenient means, thus dispensing
with the herein-before mentioned stud or pin and obtaining any required angle or
bevel.
The second part of my improvements consists in adapting two or more sets of
rings with fewer of them in each set, in order to "temple" the cloth by gripping
the selvage or edge only.
The third part of my improvements refers to the application of a roller, conical or
otherwise, by preference mounted on the "temple" cover, and provided with a
ratchet movement with suitable levers so arranged as to communicate with any
convenient moving part of the "temple" or loom (my self-acting adjusting apparatus
in combination with "temples," described and claimed in the Specification of the
Patent granted to me the 14th July 1875, No. 2532, is particularly applicable for
for this), by which the aforesaid roller is made to revolve. The roller is provided
with teeth or other rough surface so as to draw the cloth over the ring part, thus
enabling the temple" to operate near to the "shed."
"
In connection with the lever arrangement is provided a telescopical compensating
rod, or the lever is made to give so as to adapt it or themselves to the tension of the
cloth during the operation of weaving.
And in order that my Invention may be more completely understood, reference
is given to the accompanying Sheet of Drawings and to the letters and marks
thereon.

page_text: shewn. Each ring is mounted on a separate support b on which they can revolve
and at any required angle. On each ring are provided any required number of
pins c, and in order to keep these in position after being fixed in the ring, I fit
within each ring the bush 'd, which has the desired effect. I take any required
number of rings a and supports b and fit them side by side, as shewn at c in the
frame f, which may be made, when preferred, of wrought iron. The whole are held
firmly together in this frame f by means of the bolts g and h, and form what is
known as a "temple." This temple is carried on a bracket i which is fitted so as
to slide into a carrier j, which may be made of sheet iron or any suitable material.
The bracket i is retained in position in the carrier j by means of the spring / which
acts against the projection 1, and is placed in position, as shewn at Figs. 7, 8, and 9;
this spring admits of the temple being set free when any undue pressure comes
against it, and renders it less liable to damage than when held tight, as heretofore.
I am fully aware that a spring has been used for retaining the bracket, but acting
in the reverse direction, as shown in Figures 1, 2, and 3, which had the effect of
holding the temple tight in any position; this I find by practice is a very defective
arrangement.
The second part of my improvements is the adapting of two or more sets of
rings, with fewer of them in each set, to temple the cloth by gripping the selvage or
edge only, and is shewn at Fig. 10.
My improvements further refer to the application of a roller m which may be
made conical or otherwise. On the surface of this roller are provided pins, teethi
(or other rough surface), of any suitable pitch or of a similar kind to those in the
temple; I, by preference, mount this roller m in bearings on the temple cover n, and
give to it an intermittent rotary movement which is transmitted thereto by means of
the ratchet wheel o, pawl p, and spring lever q, being actuated by some moving
part of the machine. The lever q is made to spring, so that, by its motion, a too
rigid action upon the material to be operated upon is prevented.
My self-acting adjusting apparatus (in combination with these temples) described
and claimed in the Specification of the Patent granted to me the 14th July 1875,
No. 2532, is particularly applicable to these improvements. The effect of this
conical roller m is to draw the cloth over the temple, as shewn at r.
Instead of having the cover n hinged on the side of the bracket, as is ordinarily
done and shown at Figure 3, I hinge it at the end, as shewn at 8, Figs. 7, 8, and 9;
by this means it is more readily got away clear of the temple, and the cover is more
firmly held in position when hinged in this manner, being more capable of resisting
any blow which might take place in the shuttle trap.
The whole of iny improvements are applicable to temples of ordinary construction,
as shewn at Figures 7, 8, and 9.
Having now described the nature of my said Invention and shewn by Drawings
how the same may be carried into practice, I would have it understood that I do
not limit myself to the exact limits, details, or configuration of the various parts I
have explained and shewn, as the same may, of course, be varied or modified with-
out in any way departing from my said Invention, but what I claim and desire to
be secured to me by Letters Patent is,―
First. The arrangement, construction, and application of rings a in combination
with supports b and frame f, also parts connected therewith forming the temple, sub-
stantially as and for purposes herein set forth.
Second. The application of two or more sets of rings or temples having two or
more rings in each set, with or without the roller m, substantially as shewn and for
purposes herein set forth.
Third. The arrangement, construction, and application of roller m, conical or
otherwise, and parts connected therewith for transmitting motion to the same,
substantially as and for purposes herein set forth.
Fourth. The arrangement and construction of carriers j, having in combination
therewith a spring k, substantially as and for purposes herein set forth.

page_text: Fifth. The arrangement and construction of the cover n, substantially as and for
purposes herein set forth.
In witness whereof, I, the said John Hardaker, have hereunto set my hand
and seal, this Second day of October, in the year of our Lord One thousand
eight hundred and seventy-seven.
