IMPROVEMENTS IN SELF-ACTING TEMPLES FOR Looms
Year: 1871

page_text: LETTERS PATENT to John Hill, of Manchester, in the County of
Lancaster, Machine Maker, for the Invention of "IMPROVEMENTS IN
SELF-ACTING TEMPLES FOR Looms."
Sealed the 10th May 1872, and dated the 21st November 1871.
I, JOHN HILL, of Manchester, in the County of Lancaster, Machine
Maker, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN SELF-ACTING TEMPLES FOR LOOMS," to be as follows:-

page_text: of which are provided with sharp teeth. These endless bands pass
around pulleys mounted on studs fixed in plates, which are secured to a
cross bar supported by the breast beam. By increasing the distance
between the pulleys a greater length of selvage can be taken hold of,
and by varying the angle of the plates the pulleys can be set so as to
cause the endless bands to distend the fabric as it approaches the breast
beam.
In lieu of the endless steel bands with sharp teeth I also use chains or
endless bands of leather or other material in which needle points are set,
or the needle points may be set in small segments fitting into a groove
or flanged plate. In this arrangement the segments that take hold of
the selvage are carried forward by the fabric, and cause the others to
come successively into operation in the same manner as the links of an
endless chain.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Hill in the Great Seal Patent Office on the
18th May 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HILL, of Manchester, in the County of Lancaster, Machine Maker,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of November, in the
year of our Lord One thousand eight hundred and seventy-one, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said John Hill, Her special licence
that I, the said John Hill, my executors, administrators, and assigns, or
such others as I, the said John Hill, my executors, administrators, 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,

page_text: and Isle of Man, an Invention for. "IMPROVEMENTS IN SELF-ACTING TEMPLES
FOR LOOMS," upon the condition (amongst others) that I, the said John
Hill, my executors or administrators, by an instrument in writing under
my, 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.

page_text: ordinary manner. The plates e, e, are secured by set screws to the cross
bar d, and they are placed at any convenient distance apart according to
the width of the fabric that is being woven in the loom. In each plate e
are two studs that serve as fulcra for the pulleys f, f, around which the
endless bands 9, 9, pass. These bands are made by preference of gutta {
percha, but they may be of leather, steel, or other suitable material, or
endless chains may be used. Sharp teeth or needle points are let into
the bands g, g, and these teeth enter into the fabric near the selvages.
The little rollers h, h, are to prevent the deflection of the bands g in
passing from one pulley f to the other.
The mode of operation is as follows:-The selvages of the fabric which
is marked i are guided into the diagonal slots in the ends of the plates e,
as shewn in Fig. 3.; the needle points or teeth in the bands g then
penetrate into the fabric near the selvages, and as the fabric is drawn
forward by the usual taking-up motion, the endless bands are carried
round with the pulleys f in the direction of the arrows in Fig. 2. By
thus taking hold of the fabric so close to the selvages no injury is done
to the body of the fabric by the pin points, thus rendering these temples
particularly advantageous for fine or figured fabrics. The distance
between the pulleys f, f, may be varied to increase or reduce the length
of fabric taken hold of by the needle points, and the plates e¹ are or may
be set at an angle to the bar d to cause the endless bands to expand or
distend the fabric as it is carried forward towards the breast beam.
In lieu of the endless bands with sharp teeth the needle points or
teeth may be set in small segments fitting into a grooved or flanged plate.
In this arrangement the segments that take hold of the selvage are
carried forward by the fabric, and cause the others to come successively
into operation in the same manner as the links of an endless chain,
or the endless bands with sharp teeth or needle points instead of passing
around pulleys as shewn may be guided in grooved flanges cast or fixed
to the plates e.
Having thus stated the nature of my Invention, and described a con-
venient mode of carrying the same into operation, I declare that I claim
as my Invention the improved self-acting temples with endless bands or
other equivalents furnished with sharp teeth or needle points by which

page_text: the fabric is taken hold of close to the selvage and distended as shown
and described.
In witness whereof, I, the said John Hill, have hereto set my hand
and seal, this Seventeenth day of May One thousand eight
hundred and seventy-two.
