PROVISIONAL SPECIFICATION.
Improvements in Temples for Looms for Weaving.
We WILLIAM SIMPSON of 64 Edward Street, Lower Broughton, Salford, in
the County of Lancaster, Weaving Manager, and EDWARD TURNER WHITELOW
of 70 Deansgate, Manchester, in the County of Lancaster Consulting Engineer
and Patent Agent, do hereby declare the nature of this invention to be as
follows:-
Our said invention relates to improvements in temples used in weaving looms for
keeping the cloth immediately in front of the reed stretched out.
Mounted in a suitable casing hereinafter referred to as the temple box we use
three taper rollers the upper one of which is set at an angle to the lower parallel
pair of rollers. The rollers are roughened fluted or provided with teeth or pins
either on the temple rollers themselves or on rings revolving thereon in order that
they may engage with the cloth as is well known. We however prefer to provide
the upper inclined roller with teeth at one end only so as only to engage with the
selvedge. The rest of the upper roller is in this case plain.
Pivoted under the temple box we use a bell crank lever one arm of which bears
against projecting part of the cover or cap of the temple box in such a manner
as to form a pair of jaws the acting parts of which may in some cases be serrated
or faced with indiarubber leather or the like means for increasing the grip of
the jaws on the cloth. The gripping action is produced by a spring bearing on the
other arm of the bell crank lever. The latter arm carries a bowl or anti-friction
roller so placed that at each advance of the slay for the purpose of beating up a
part of the slay comes into contact with the anti-friction roller and overcoming the
spring causes the jaws to open and to momentarily release the cloth in order that
it may advance to the taking up roller or cloth beam. As the slay retires the
spring again closes the jaws and prevents the contraction of the cloth.
The temple is mounted on an upright spring bar secured at its lower end to the
cross rail or other convenient part of the loom and provided at its upper eud with
sliding bolts and adjusting parts to enable the temple to be accurately set in the
proper position in relation to the slay.
By mounting the temple in this manner-op-an upright spring bar it can readily
yield in case of the shuttle being accidentally caught between the reed and the
temple.
A detent is provided for enabling the weaver to maintain the jaws in an open-
position when ass sometimes the case it is necessary to allow the cloth to move
freely through-the-temples.
That part of our said invention which relates to the spring jaws and the improved
method of mounting the temples on upright springs is applicable to other
constructions of temples.
It is to be understood that as is usually the case a temple such as hereinbefore
described is employed for each selvedge of the cloth being woven,

DESCRIPTION OF THE DRAWINGS.
Fig. 2 is a plan of the temple with the cover removed.
Mounted in a suitable casing a hereinafter referred to as the temple box we use
three rollers b c d preferably taper and having the upper roller o set at an angle
to the plane in which lie the axes of the lower rollers 6 & d. The rollers are
provided with teeth or pins in the usual manner but the upper roller is provided
with teeth at its outer end only. To further prevent shrinkage of the cloth as the
weaving proceeds a clamp e is used. The said clamp bears with its front edge el
firmly against the under edge of the temple cover f and thus positively grips the
cloth except at the moment of beating up by the reed.
:
The clamp e is formed as a bell crank lever pivoted at 9 to a projection from the
bed plate of the machine. The pressure of the clamp e is obtained by a spring h
bearing against a stud-j on the lower arm of the bell crank lever. To enable the
clamp e to open each time the slay approaches in order that the cloth may be pulled
through the temples by the take up motion a bracket & carrying a bowl is
secured to the lower arm of the clamp. A contact piece or projection m is attached
to the slay bottom in such a position that when the slay beats up the part m bearing
against the bowl causes the edge of the clamp e¹ to momentarily release, its grip
of the cloth. In some cases we may serrate the front edge of the clamp e' and
the under side of the temple cover for we may provide such with facings of
india rubber leather or similar non-slipping materials for the purpose of augmenting
the grip on the cloth.
The temple is mounted on an upright spring bar secured at its lower end to
the cross rail r or other convenient part of the loom. The object of this mode of
mounting is to enable the temple to yield in case the shuttle be accidentally caught
between the reed and the temple.
:
To enable the weaver to work the loom backwards as is sometimes necessary the
clamp may be released by a lever n mounted on the taking up motion rod & being
brought to bear on the stud j.
It is to be understood that a temple box with its rollers and clamp such as
hereinbefore described is employed for each selvedge being woven.
•
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
In loom temples the combination of a bell crank lever e acting directly as a

slay the springh for effecting the grip and the releasing lever n substantially as and
for the purpose set forth.
