SPECIFICATION filed in pursuance of the conditions of the Letters
Patent, and of an Order of the Lord Chancellor, by the said Edwin
Heywood in the Great Seal Patent Office on the 25th September 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWIN,
HEYWOOD, of Manchester, in the County of Lancaster, Manufacturer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of March, in the year
of our Lord One thousand eight hundred and seventy-four, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Edwin Heywood, Her special
licence that I, the said Edwin Heywood, my executors, administrators,
and assigns, or such others as I, the said Edwin Heywood, 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, and Isle of Man, an Invention for
IMPROVEMENTS IN SELF-ACTING TEMPLES FOR LOOMS," upon the condition
(amongst others) that I, the said Edwin Heywood, 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 on or before the Thirtieth day of September One thousand
eight hundred and seventy-four..

page_text: NOW KNOW YE, that I, the said Edwin Heywood, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement (that is to say) :- :
The effect which I propose to obtain by my Invention is a good hold
of the selvages, which will enable me to get a full stretch of the fabric,
and at the same time allow the temples to adapt themselves to the
lateral movement of the fabric as is the case with hand temples.
+
In the construction of my Invention I employ a series of small
detached metal segments, into which the pins for holding the selvages
are secured. These segments are loose in the grooves of a box, and are
carried round by the action of the fabric as it is being woven, and drawn
forward by the taking-up roller.
In order to allow the temples to adapt themselves to the lateral motion
of the fabric I secure each box to a rod, and this rod is supported by
brackets fixed to the breast beam or loom sides, consequently as tho
fabric moves from one side to the other it carries the temples with it.
And in order that my Invention may be fully understood and readily
carried into operation I will proceed to describe the accompanying
Shect of Drawings.

of my improved self-acting temples are fixed; Fig. 2 is a front elevation;
and Fig. 3, a plan of the temples; these views are drawn half size.

stretched.
.
In Fig. 1, a is the breast pin; b, the taking-up roller; and c, the
cloth beam; which parts are made as usual. To the breast beam aro
bolted the brackets d, d, which support the flat rode, and to this rod e
are fixed the boxcs f, f, containing the angle-shaped segments g, in
which the pins are fixed, as shewn in Fig. 4, for holding the selvages of
the fabric. These segments are loose in the grooves of the box, as shewn
best in Fig. 5, and they are prevented from being lifted by the stretching
of the fabric by the top plate f¹, which is screwed down to the elevated¨

page_text: part in the centre of the box f, which forms the groove or race wherein
the segments work. The position and distance of the boxes f, f, on
the rode are regulated according to the width of the fabric that is being
woven by means of the pins f2, which fit in holes, as shewn in Fig. 3.
The distance between the holes in the rod e and box fare so arranged
that by moving the pins fone hole-it will give one-eighth of an inch
wider or one-eighth of an inch narrower to any width as required.
:
The rod e rests upon the lower parts of the brackets d, and it is
prevented rising by the upper parts d³, thus it will be seen that this
form of bracket will allow the rod e to move freely endways, backward
or forward. This movement endways of the rod e is to allow the temples.f
to adjust themselves to the motion of the cloth sideways, but to prevent
the forward motion of the rod e I place a lug under the end of the top
part d² of the bracket d, and in order to prevent its backward move-
ment while the fabric is being woven and the passage of the shuttle
home I place a pin d³ in the top part d² of each bracket which the rod e
rests against, but in case the shuttle should be stopped in its passage by
some obstruction betwixt the reed and the temples these pins d³ being
made of wood, soft metal, or other suitable material sufficiently strong to
resist the pressure of the cloth, break by the pressure of the shuttle, and
thus prevent any damage to the same, space being left in the length of
the two parts d' and d² of the bracket d to allow the rod e to recede
backwards sufficiently to save the shuttle.
When the loom is at work the fabric is drawn forward by the usual
taking-up motion, and the selvages of the fabrics cause the segments to
travel in the grooves in the boxes f in the direction of the arrows in
Fig. 3, the pins in the segments releasing themselves from and catching
fresh hold of the selvages as the work proceeds. The length of the selvage.
caught hold of by the segments can be varied by increasing or reducing
the straight part of the grooves in the boxes f.
In order to impart an additional stretch to the fabric or to ensure its
being wound at its full width on the cloth beam I place a second pair of
temples near to the taking-up roller, as shewn in Fig. 1.
Having thus stated the nature of my Invention and described ther
manner of performing the same, I wish it to be understood that I do
not intend to limit myself to the details given, as they may be varied
according to the nature or quality of the fabric to be woven and to the;

page_text: peculiar construction of the loom to which they are attached; I would
also remark that my improved self-acting temples may be used for other
purposes where stretching is necessary.
I claim,―
First. The improved mode of constructing self-acting temples with
segments, as shewn and described.
Secondly. Supporting self-acting temples in such wise that they can
adapt themselves to the lateral motion of the fabric in the loom.
Thirdly. The pins d³ made of wood, soft metal, or other suitable
material that may be broken or cut by the rode when the shuttle is
caught against the box of the temple.
And, Lastly. The application of an additional pair of self-acting
temples placed near the taking-up roller or cloth beam to stretch the
fabric before it is wound on the beam.
In witness whereof, I, the said Edwin Heywood, have hereto set
my hand and scal, this Twenty-fourth day of September, One
thousand eight hundred and seventy-four.
EDWIN HEYWOOD. (LS).
