A SELF-ACTING TEMPLE TO BE USED IN THE OPERATION OF WEAVING BY POWER OR HAND LOOMS
Year: 1833

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
GRAHAM, junior, of the City of Glasgow, Cotton Spinner and Power Loom
Manufacturer, send greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twenty-second day of May, in the third year of His reign, did,
for Himself, His heirs and successors, give and grant unto me, the said William
Graham, junior, His especial licence, full power, sole privilege and authority, that
I, the said William Graham, junior, my executors, administrators, and assigns, or
such others as I, the said William Graham, junior, my executors, administrators,
or assigns, should at any time agree with, and no others, from time to time and
at all times during the term of years therein expressed, should and lawfully
might make, use, exercise, and vend, within England, Wales, and the Town of
Berwick-upon-Tweed, the Invention of "A SELF-ACTING TEMPLE TO BE USED IN
THE OPERATION OF WEAVING BY POWER OR HAND LOOMS," communicated to me by
a certain Foreigner residing abroad; in which said Letters Patent is contained
a proviso that I, the said William Graham, junior, shall cause a particular
description of the nature of the said Invention, and in what manner the
same is to be performed, to be inrolled in His said Majesty's High Court
of Chancery within six calendar months next and immediately after the date
of the said in part recited Letters Patent, as in and by the same, reference
being thereunto had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
William Graham, junior, do hereby declare the nature of the said Inven-
tion, and the manner in which the same is to be performed, are fully described
and ascertained in and by the following description thereof; reference being had
to the Drawing hereunto annexed, and to the figures and letters marked 5
thereon (that is to say): :-
The Invention consists in apparatus affixed near each end of the breast
beam, which being acted on by the swinging or traversing of the lay in beating
up the weft, are caused to open and shut, as will be fully described hereafter;
and by means of this apparatus the cloth is held to the width at which the reed 1
leaves it after having beaten up the weft.
In order that the Invention may be fully described and understood, I will
proceed to describe the Drawing hereunto annexed, first observing that the
same letters of reference indicate similar parts in each of the Figures.
DESCRIPTION OF THE DRAWING.
1
Figure 1 is a plan of one of the self-acting temples; Figure 2 is a front
edge view, and Figure 3. perspective view thereof. A is a plate which is
affixed to the breast beam of the loom at the slit or gap B, by means of a
screw bolt passing through the breast beam; and where different widths of
fabrick are woven in the same loom, the temples must be so constructed as to 2
allow of their being brought nearer to or recede farther from each other, by
means of the slits B formed in the plate A. On to the plate A is fixed, by
means of a screw, another plate C, having a projection D, which is turned
down at right angles at E, the object of which will be hereafter described.
The outer end of the plate C is turned over, so as to produce a parallel plate F, 2
leaving a space between them. G is a spring affixed to the plate C by rivetting.
or otherwise, and on the part H of the face of this spring is formed teeth or
grooves cut in a line with the direction of the cloth, these teeth or grooves
being intended to hold the cloth when the spring is pressing upwards against
the plate F. I is a lever which has its fulcrum at J, on the plate A, and at 3
one end of the lever I is formed a projecting wedge K, which is pressed
between the upper plate F and the spring G every time the lay beats up the
weft, by the lay coming in contact with the other end L of the lever I, this
end L being turned down, as shewn in the Drawing, for that purpose.
Having described the manner of constructing the apparatus which constitutes 3
the self-acting temple, I will now describe the manner of working, first
observing that there is to be one of the apparatus placed near each end of the
breast beam, that is, in such a position that they shall just embrace the outer

page_text: edges or selvages of the fabric between the plate F and the spring G, and they
are so placed as to take hold of the fabric as near as possible to the point at
which the reed strikes up the weft, but the reed is prevented being injured by
the bottom of the lay coming in contact with the parts E, which stops the lay
from approaching too near to the temples at the time of beating up the weft;
and at the time the lay has nearly finished its stroke it comes against-the
part L of the lever I, which drives the wedges K between the plates F and the
springs G, and causes them to separate to permit of the fabric being drawn
through them, but immediately on the receding of the lay, after having beaten
up the weft, the springs G will press up against the plates F and retain the
cloth between them, the wedges K being forced out by the pressing up of the
springs, and by this means the fabric will be kept to the width at which the
reed leaves it.
I have not thought it necessary to shew a loom of any of the various
constructions, 'which are well known, the Invention only relating to the
parts described, which any competent mechanist will readily construct and
apply.
And I would have it understood that what I claim as the Invention
communicated to me, is the apparatus above described, when applied to
power or hand looms for the purpose of keeping the fabric to the width at
which the reed leaves it.
In witness whereof, I, the said William Graham, junior, have hereunto
set my hand and seal, this Thirty-first day of August, in the year of our
Lord One thousand eight hundred and thirty-three.
Taken and acknowledged by William
Graham, junior (party hereto), at
Glasgow, in the County of Lanark,
this Thirty-first day of August, One
thousand eight hundred and thirty-
three. Before me,
