Improvements in Temples for Looms.
We, WILLIAM LUPTON, HENRY EDWARD LUPTON and JOHN CLEGG LUPTON, all
of Grange Iron Works, Accrington, Loom Temple Manufacturers, 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:-
Our said invention relates to temples for looms, either of the "trough-and-roller "
or "side roller" type, which at present are made with their points or teeth in straight
parallel rows, with a tendency for one row of teeth to loose its "grip" on the cloth
before the next row comes into contact therewith, and thereby permit or cause an
uneven pull on the cloth.
The object of our invention is to give a uniform and continuous "
generally to improve the "tentering" action of the temples.
grip" and
In carrying out our invention, and as applied to "trough-and-roller" temples, we
first form the rollers with the usual circumferential grooves, and then cut through
such grooves longitudinally with a ✓ shaped tool to produce the required teeth, but
instead of the longitudinal grooving being parallel with the roller axis as heretofore,
we cause it to be diagonal to such axis, either by a suitable movement of the grooving
tool, or by a slight rotation and forward motion of the roller. The resulting effect of
so producing the teeth is that each tooth forms part of, and lies at the junction of
two (or inore) spirals, one running transversely round the roller and the other running
lengthwise of the roller, and with the latter arranged to produce what might be
called a right-hand "spiral on one half of the roller, and a "left-hand " spiral on the
other half of the roller, a most efficient pull is obtained on the cloth, besides ensuring
of the teeth having a continuous "grip."
In applying our invention to the rollers of "side" temples, we arrange the points
or teeth in the same or similar diagonal paths, either by moving the forming tool, or
pinning-in tool, in the path of a spiral, or by moving the rollers past such tool with
a slight forward and rotating movement. In these "side-temple" rollers we also
arrange the teeth slightly closer at and towards one end than at the other end, or we
graduate the spacing of the teeth from end to end of the roller, and thereby give a
better grip on the "selvage" and front edge of the cloth.
And in order that our said invention may be more readily understood and carried
into practical effect, we have hereunto annexed a sheet of drawings, and will now
proceed to describe the same with the various letters of reference marked
thereon.
Fig. 1 represents (on an enlarged scale) a soft metal (right hand) "side" or
"end" temple roller, with the teeth raised out of the metal, and Fig. 2 a hard
metal (right hand) "side" temple roller with the teeth pinned into the metal in
the ordinary way, but arranged in accordance with our invention.
Fig. 3 represents part front view,. Fig. 4 an end view, and Fig. 5 a transverse
section of a "trough-and-roller" temple, with the roller made in accordance with our
invention, and shewing its combination with a special form of bearing cap, and
trough.

rollers.
"
Referring to Fig. 1, which represents a "side temple" roller for the right-hand
side of a loom, it will be readily seen how each row of teeth lies in diagonal relation
to the axis of the roller, commencing for example at (a) and ending at (6), whilst
each tooth lies in an independent transverse spiral (c)-(d). Each tooth aiso lies
in other spirals, which serve to augment the general efficiency of the roller.
The diagonal arrangement of the teeth of the hard metal roller (see Fig. 2) is
precisely similar to that shewn in Fig. 1, and the spacing between the teeth in both
rollers is, by preference, slightly less towards and at one end, than at the other end,
in order to provide a greater number of teeth at such end for the better gripping of
the "selvage," and front side, of the cloth. For a left-hand "side" temple roller the
arrangement of spirals is reversed, i.e., the transverse spirals (c)-(d) incline towards
the left, and the longitudinal spirals (a)-(b) fall towards the right-hand end of the
roller.
Fr
In the rollers of "trough-and-roller" temples the teeth lie at the junction of
the transverse spirals ef and longitudinal spirals g-h, as shewn in Fig. 3, and one
end, or half, of the roller has a "right-hand spiral, and the other end or half a
"left-hand "spiral. This same disposition of the teeth in right, and left hand
spirals is applied to the "side temple "rollers as aforesaid, but the direction of the
spirals a-b in relation to the spirals c-d of say, the right-hand
"side roller is
opposite to that of the same spirals of the right-hand end of a trough-and-
roller" temple owing to the cloth travelling over, instead of under the roller.

Whilst our invention may be said to consist in disposing of the teeth in longitu-
dinal spirals, it may also be described as breaking up "the straight parallel rows
hitherto adopted and causing the teeth to lie in irregular order, or if the roller be
viewed endwise, distributing the teeth in a manner which intercepts or breaks up
the parallel rows of spaces, and gives a mixed or confused aspect to the teeth, which
affords the double advantage of a uniform grip on the cloth, and an increased
"tentering" action of the teeth.
The pitch of the said longitudinal spirals, or diagonal setting of the teeth, may
vary according to requirements in weaving, and may be either quick, or slow, and
according to such pitch we may vary the latteral disposition of the teeth.
As aforesaid the transverse spirals vary in their relation to the said longitudinal
spirals, according as they are for the right-hand or left-hand edge of the cloth, or
right or left-hand end of the temple, or according as the cloth passes over, or under
the roller, or rollers.
In Figs. 3, 4 and 5 we shew the improved "trough" roller in combination with a
trough (E), and bearing cap (F), which permit of a longer roller being used, and a
wider cloth being made, than a loom temple made with an ordinary bearing cap.
The roller bearing (see Fig. 4) is made about half its usual thickness at (G) and
part (F) of the cap (F) is brought down, or made to fit, against the reduced part of
the bearing as illustrated.
The head of bolt (I) is thereby permitted to lie beneath the level of the cap (F)
and thus be out of the way instead of projecting beyond the cap as heretofore.
•
The said bearing and cap, our improved roller, and the trough (E) (which causes
the cloth to travel over about 2/3rds of the rollers circumference), constitute a most
efficient "trough-and-roller" temple. The said "side" temple rollers may be com-
bined with the "pivot cap of our well known "crown temples" shewn in Fig. 6,
which enables the rollers to be readily renewed or adjusted, and which consists of a
piece of stamped metal (H) with elongated opening (K) and raised parts (L) to fit
the roller ends, and is adjustably fixed by nut (M).
Having thus particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
