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."
Scaled the 22nd November 1878, and dated the 18th June 1878.
PROVISIONAL SPECIFICATION left by the said John Hardaker at the Office
of the Commissioners of Patents on the 18th June 1878.
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 as here-
after described.
The object of my Invention is an arrangement of parts by which the same may
be introduced into a less space and worked therein. I provide, mounted and fixed
in suitable bearings on the breast rail of the loom, a rod on which I mount loosely
an upright lever, which is held in position by means of a spring applied in any
convenient way to admit of a radial movement, substantially for the purposes set
forth in the Specification of the Patent granted to me the 14th July, 1875, No. 2532.
The herein-before mentioned upright is provided with openings to admit of pieces
or levers necessary to produce the radial movement above referred to. In the
opening at the bottom of the upright lever is a stationary piece, set in position on ·
the rod by means of a set screw or its equivalent, and having a projection or other
piece to slide on the rod, made suitable for adjusting purposes and to keep it in
position while being moved to suit the various widths of material being woven.
The rod above mentioned may be either plain, square, or have a groove or flat part
or parts thereon instead of the projecting part or piece. At the top of the upright
lever is a horizontal lever which is provided with a slide to admit the temple bar,
on which is mounted the temple. I provide a loose collar to suit the temple bar
with set screw by which the temple can be set in position, and held there by means
of a spring fixed to the slide with its vibrating end in contact with the collar, or
otherwise to hold the temple in position and enable it to recede when the shuttle
or other obstruction intervenes between it and the slay in the operation of weaving.

In the
The object of my Invention an arrangement of parts by which the same may
be introduced into a less space and worked therein. I provide, mounted and fixed
in suitable bearings on the breast rail of the loom, a rod on which I nount loosely
an upright lever, which is held in position by means of a spring applied in any
convenient way to admit of a radial movement, substantially for the purposes set
forth in the Specification of the Patent granted to me the 14th July 1875, No. 2532.
The herein-before mentioned upright is provided with openings to admit of pieces
or levers necessary to produce the radial movement above referred to.
opening at the bottom of the upright lever is a stationary piece, set in position on
the rod by means of a set screw or its equivalent, and having a projection or other
picce to slide on the rod, made suitable for adjusting purposes and to keep it in
position while being moved to suit the various widths of material being woven.
The rod above mentioned may be either plain, square, or have a groove or flat part
or parts thereon instead of the projecting part or piece. At the top of the upright
lever is a horizontal lever which is provided with a slide to admit the temple bar,
on which is mounted the temple. I provide a loose collar to suit the temple bar
with set screw by which the temple can be set in position, and held there by means
of a spring fixed to the slide with its vibrating end in contact with the collar, or
otherwise to hold the temple in position and enable it to recede when the shuttle
or other obstruction intervenes between it and the slay in the operation of weaving.
In the projection from the horizontal lever I provide a set screw with its end in
contact with another intermediate piece to facilitate adjustment. I provide toothed
rings with their carriers, varying in sizes or dimensions, and so arranged as to form
the temple conically. I also provide a conical or other suitable cover.
And in order that my Invention may be more completely understood, reference
is given to the accompanying Drawings and to the letters and marks thereon.
Figure 1 represents a front elevation; Figure 2, a side elevation of one arrange-
ment of my improvements.
Figure 3 is a front elevation; Figure 4, a side clevation; Figure 5, a plan looking
at the top of another arrangement of my Invention.
*. Figures 6. 7. and 8 are details of various parts of the apparatus.

page_text: I will now proceed to describe Figures 1 and 2. I provide a fixed rod a, which
is mounted in suitable bearings on the breast rail of a loom. b is an upright
lever mounted on the shaft a; c is a spring, which I apply for the purpose of
holding the lever b in position, so as to admit of a radial movement substantially
for the purposes sot forth in the Patent granted to me 14th July 1875, No. 2532.
The upright lever b is provided with opening d to admit of the lever e necossary
for producing the radial movement above referred to.
I provide another opening at the bottom of the upright lever b, in which is
provided the stationary piece g fixed in position on the rod a by means of the
set screw h or its equivalent, and having a projection or key i fitted in the groove.
in the rod; such projection or key is provided so as to keep the stationary
piece in position whilst being adjusted to suit the various widths of material
being woven.
The rod a may be arranged as above described, or of any convenient shape for
the purpose of retaining the stationary piece in position.
At the top of the upright lever b is a horizontal lever, various constructions of.
which are shewn, not only at Figures 1 and 2, but also in the other Figures, varying
in some of their parts, but those parts corresponding have the same letters marked
thereon.
j is the horizontal lever, which has provided thereon a slide at k (Figures 4, 5,
and 6) to admit of the temple bar l, on which is mounted the temple m, which I
will describe hereafter. I provide a loose collar n to suit the temple bar 1, which is
fixed thereon by means of the set screw o. By this means the temple m can be
set in position, being held in such position by a spring p, as shewn at Figure 6.
In some cases I make the spring adjustable, as shewn at q, Figures 7 and 8, and
fix it at any desired position in the slot or groove by means of the bolt 8.
The object of these arrangements is to hold the temple m in position; at the
same time to enable it to recede when the shuttle or other obstruction intervenes
between it and the slay in the operation of weaving, substantially for the purpose
set forth in the Specification of the Patent granted to me the 9th April 1877,
No. 1377.
Under the horizontal lever j, shewn at Figures 1 and 2, I provide a projecting
part u, and in it a set screw in contact with an intermediate piece or lever u³,
such lever being in contact with the lever e, whereby the horizontal lever j is
adjusted.
Another arrangement or modification of my Invention is shewn at Figures 3, 4,
and 5, in which arrangement I mount the rod a loose in its bearings w with the
upright lever x mounted thereon, capable of adjustment to suit the various widths
of material. The lever x is fixed in position on the rod a by means of the set
screw y. One end of the rod a is provided with the spring 1 to admit of the
necessary radial movement of the lever .
In this my second arrangement I provide a second rod 2, on which I mount a
boss 3, having projecting fingers 4 passing on to the rod a in order to retain it in
position. On the same boss 3 is provided a projecting arm 5, which passes through
an opening in the upright lever, and is brought in contact with an adjusting
lever 6, such adjustment being effected by means of the set screw 7 acting upon
the horizontal lever j or bar 1, and for the purpose of retaining the temple in
position.
When preferred I employ a runner 8 at the end of the projecting an 5 to
reduce the friction upon the adjusting lever 6.
My improvements further consist in constructing the temple in a conical or
tapered form for the purpose of equalizing the tension, thereby obviating the
marking and damaging properties. In this case the supports 9 are gradually
increased in dimensions from the point 10 towards the end 11, and in order to do
this I make the supports 9 varying in sizes and dimensions, as shewn.
At Figures 3 and 5 I have shewn the supports 9 constructed in a similar manner
to those described in the Specification of the Letters Patent granted to me the 9th

page_text: April 1877, No. 1377, except so far as tapering from a larger to a smaller size; but
I distinctly wish it to be understood that I do not confine myself to this method
of supporting the toothed tapering rings, as various other methods may be employed
so as to form a conical temple, and I have shewn one variation in the means of
supporting the toothed tapering rings at Figure 9.
In connection with this arrangement of temple a suitable taper or conical
cover 12 with edges 13 and 14 working independent of each other, and capable of
adjustment in their bearings 15 and 16 to suit various qualities or thicknesses of
materials, and this cover 12 may be applied on the top or under side of the
material.
Having now described the nature of the 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 precise limits, details, or configuration of the parts I have
expressed and shewn, as the same may, of course be varied or modified without in
any way departing from the nature or principle of my Invention, but what I
claim to be secured to me by Letters Patent is,-
First. The arrangement, construction, and combination of the various parts
forming the apparatus for admitting of a horizontal and vertical movement or
vibration of the "temples," substantially as and for purposes herein set forth.
Second. The arrangemont, construction, and combination of the slide, spring,
collar, and temple bar, substantially as and for purposes herein set forth.
"
Third. The arrangement, construction, and application of toothed rings and their
supports, varying in sizes and dimensions, for the purpose of forming the " temple
conically, or modifications of the same, substantially as and for purposes herein set
forth.
Fourth. The arrangement, construction, and application of a conical cover or
other modifications of the same in combination with my arrangement of conical or
other modified form of "temple," substantially as and for purposes herein set
forth.
In witness whereof, I, the said John Hardaker, have hereunto set my hand
and seal, this Sixteenth day of December, in the year of our Lord Ono
thousand eight hundred and seventy-eight.
