Improvements in or connected with the Temples of Looms for
Weaving.
I FRANK JEROME DUTCHER of Hopedale, County of Worcester, State of
Massachusetts, one of the United States of America Manufacturer 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:—
In the manufacture of cloth in looms, it frequently happens that an end or
portion of the weft thread gets outside the selvage and is left as a protruding end.
In mills it is customary to inspect the cloth and trim or cut from the selvage
these ends.
The object of this invention is to obviate the formation of these projecting ends
and the consequent necessity of inspecting the cloth.
This object has been accomplished by providing the temple with a thread cutting
device or shear, to cut off the ends of the threads.
This invention therefore consists in a loom temple having a thread cutting
device or shear by which to trim off any weft threads which are left by the shuttle,
so as to project beyond the selvage.
Fig. 1 in front elevation partially broken out represents a temple with a thread
cutter embodying this invention.
Fig. 2 a longitudinal section of the temple shown in Fig. 1.
Fig. 3 a section in the line X, Fig. 2, looking to the right.
Fig. 4 is a detail showing one member of the cutter removed.
Fig. 5 shows the other member of the cutter.
The pod a, cap b, having the ears 61, 62, the temple roller e herein represented
as composed of wood, and adapted to rotate on journals d, e, one part of the
journal e being provided with a screw thread turned into the ear 63, are and may
be all as usual in loom temples.
The enclosed drawing shows only the head of the temple, its shank or part to
sustain the temple head on or with relation to the breast beam, being omitted, as
such support may be of any usual or suitable construction so long as the temple
head is permitted to move backwards and forwards as the reed meets the fell of
the cloth in weaving.
Instead of the particular roller shown, any other usual form of temple roll may
be employed.
The pod a near its outer end is provided with a semi-annular groove c', and the
cap has a like groove 7,3 located substantially in line with it, see Fig. 3.
The roll C in this instance of this invention has been provided at one end with
a thread cutting mechanism or device, which in this embodiment of this invention
consists essentially of two blades or members 9, h.
The blade g is substantially annular in shape, see Fig. 5, it having however a
cutting lip g², and a teat 2.
This blade is mounted at or made to surround one end of the roll, and
its lug 2 enters a notch in the cap b, the teat preventing the rotation of the
said member with the roll, the cutting edge g2 being left standing substantially
as represented in Fig. 3, with its edge substantially opposite or in line with the
edge of the pod a, over which the cloth travels.
g
The blade or cutting member h, as herein represented, has its periphery
provided with a series of teeth h', and at its interior the said blade or member
has a series of prongs h, which enter notches in the end of the roll, so that the
said blade or member rotates in unison with the roll, causing the cutting edges h¹

page_text: to pass one after the other the cutting edge 92, the edges co-acting as shears to
separate or sever any threads projecting outwardly from the selvage, which ends
in the movement of the cloth, pass between the cutting member.
In practice it is quite essential that the movable member of the cutter fit at
all times closely against the stationary member g, to thus ensure a clean cut.
To do this, the movable member must be restrained from unduly tipping out of
vertical plane, during its rotation.
This has been effected by combining with the member ha washer or pressure
plate n, which is held up to its work in a yielding manner by a suitable spring
as o, located between the head e² of the journal e, and the said pressure plate.
To prevent the entrance of dust or other particles into the space between the
journals or bearings and the interior of the temple roll, the temple has been
provided with washers as p, p' which will preferably be of some fibrous material;
or material other than metal.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1: A loom temple provided with a thread cutting mechanism carried thereby,
to operate substantially as described.
2: A loom temple having a roll, provided with a cutter adapted to rotate
therewith, and a second non-rotating member held in position at one side thereof,
to operate, substantially as described.
3-A loom temple roll having an attached rotating cutter, and a non-rotating
cutter located at one side of it, and means to ensure the close contact of the two
members of the cutter, substantially as described.
4: A loom temple containing a head consisting of a cap, and pod, journals, a
temple roll, and having a non-metallic or flexible washer surrounding one or both
of the said journals, to operate substantially as described.
