_ Improvements in Temple Rollers used in Looms for Weaving.
I, NORMAN BLEZARD, of Grove House, Padiham, in the County of Lancaster,
Machinist, do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by
the following statement:-
This invention relates to the construction of what are known as "temple rollers,"
used in looms for the purpose of keeping the cloth to its full width as it is woven.
These rollers, over which the cloth passes, are mounted on the loom a short distance
in front of the reed, and are provided with rows of pins or teeth which enter the
cloth as it passes over them, and stretch or draw the selvedges outwards as the
rollers revolve.
Owing to the manner in which the pins or teeth have hitherto been set, the
rollers have had a tendency to "fray" or open out the threads of the cloth, and to
produce "faults" mainly in consequence of (1) a long row of teeth acting against
a single thread in the weft, and (2) because the spiral line in which the teeth were
set had an equal pitch throughout and did not increase the number of teeth where
the pull of the weft is greatest.
The object of my invention is to remedy this defect and thereby improve the
action of the rollers and so prevent them from "fraying" the cloth.
The manner of carrying my invention into practical effect will be readily under-
stood on reference to the sheet of drawings hereto annexed, and the following
explanation thereof. (The drawings represent only one form of the various kinds
of temple rollers in use and to which the principle of my invention applies.) Fig. 1
is an explanatory diagram; and Fig. 2 is a side elevation of a temple roller"
made according to my invention, and Figs. 3 and 4 a similar diagram and elevation
of a modification thereof illustrating another part of my invention.
On referring to Figs. 1 and 2, it will be seen that the teeth are set or placed in
a spiral line running round and round the roller like the thread of a single threaded
screw but having its pitch gradually diminishing from one end of the roller to the
other. By this arrangement the teeth at one end are longitudinally nearer together
than at the other end, and so have a better grip upon the selvedge.
On referring to Figs. 3 and 4, it will be seen that the longitudinal lines formed
by the teeth in the direction of the length of the roller are curved, slightly spiral,
or skewed, and do not run, as heretofore, in straight lines; and therefore they do
not enter the cloth in the line of one thread only of the weft; consequently the
strain on the cloth is more evenly distributed and "fraying" is avoided.
The teeth, set or placed in the positions hereinbefore described, may be "struck
up," or cut into the solid roller by suitable tools, or inserted in the usual manner
as practised heretofore.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is-
1. A temple roller" wherein the teeth, round the roller, are set or formed on a
snival line which has its nitch or thread gradually diminishing from one and of

page_text: the roller to the other, as hereinbefore described and illustrated by Figs. 1 and 2 on
the annexed drawing.
2. A "temple roller" wherein the teeth are set (or formed in longitudinal lines
in the direction of the length of the roller, which lines are curved, slightly spiral,
or skewed, but are not straight lines; as hereinbefore described and illustrated by 5
Figs. 3 and 4 on the drawings annexed.
