Improvements in Temple Mechanism for so-called Automatic Looms
for Weaving.
I WILLIAM FRANKLIN DRAPER of Hopedale, County of Worcester, in the 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 per-
formed, to be particularly described and ascertained in and by the following
statement:
}
In so-called automatic looms, such as represented in the specification of Letters
Patent No. 22939, dated November 27, 1894, wherein the filling is supplied to the
shuttle in the shuttle box while the loom is in action, the filling carriers are sup-.
ported above the shuttle-box and the outer end of the filling on the filling carrier
is connected to a filling end holder, so that after the filling-carrier has been put.
into the shuttle and the shuttle thrown through the shed, the said filling thread
so held will be automatically threaded into the delivery eye of the shuttle,,
Each insertion of a new filling-carrier into a shuttle consequently leaves outside
the selvage a filling-end of from fifteen to twenty inches long, it leading from the
selvage to the said filling end holder.
This filling end must be removed, else it is liable to be caught by subsequent
shots of filling making bunches at the selvage which damage the appearance of
the goods and lessens its saleable value in the market.
This invention has for its object to provide a cutter which will operate promptly
and unerringly to cut off this filling.
In the invention to be herein described and claimed, a reciprocating temple is
provided with blades, they acting to cut off the filling end if between them, when
the lay is being moved forward to strike and move the temple.
The cutting devices herein shown operate to catch and cut off the filling-end
before the temple carrying the cutter is moved towards the breast-beam as the
lay beats in the filling.
The movable cutter blade normally stands in a plane outside the path of the
filling-end, and the movement imparted to it is such that at each beat of the lay
n hook of the blade catches behind the filling end, if one is present, and having
engaged said end, the blade, in its movement toward the breast beam under the
influence of the lay cuts the filling-end between itself and the stationary blade,
the cutting movement being substantially completed as or a little before the
temple is ready to start with the lay towards the breast-beam.
In this way, the filling-end when present is promptly cut off.
The movable cutter blade is made as a sliding bar having, as shown, two arms
provided each with a hook to engage the filling-end and draw it against the
stationary blade carried by the temple and cut the filling end, the opposite end of
said bar having a heel which extends below the temple head in position to be
struck by the lay as it comes forward, the lay causing said blade to be moved to
effect the cutting of the filling-end.
A spring operating with the temple, head and bar acts normally, to keep its

page_text: hooked end elevated above the plane in which the filling end lies, the hooked or
cutting end of the bar being lowered to get behind the filling-end if present by
each forward blow of the lay in beating in the filling.
The bar of the cutter blade has a forward stop lug to limit its forward movement
by the spring mentioned, and a shoe which slides on a depending ear of the temple
bar, and at its upper side the bar has a projection which as the free outer end
of the bar rises meets the overhanging wall of the slot in the head in which the
bar slides.
Fig. 1 is a top or plan view of a thread cutting temple embodying this invention.
Fig. 2 is a side elevation thereof.
Fig. 3, a front end elevation, the toothed roller being omitted.
Fig. 4 a partial section taken longitudinally through the cutter blade and part
of the temple.
Fig. 5 shows the cutter blade detached and enlarged and
Fig. 6 is a detail to be referred to.
The loom temple, consisting of the stand A, adapted to be secured to the breast-
beam of the loom, the slide bar B in said stand and having the pod B', the cap B³,
the heel B³ attached to the pod by screws B, and the toothed roller B³ between
the pod and cap and turning on usual pivots, are and may be all as usual, the
said stand, in practice, containing a spring which surrounds the bar B to normally
keep it pressed forward toward the lay, all in usual manner.
The pod, see Figs. 3 and 4, is slotted at a to receive a steel blade a', forming
the stationary blade of the cutter, said blade having, as shown in Fig. 3, an open
space at both sides of it.
The slot a is enlarged at a* in the pod and is extended into the cap and through
an ear secured to or formned as a part of the slide bar.
The slot a receives a sliding cutter blade C, the acting front end of which is
shown as slotted at 2 to leave 2 arms c', e, each having a suitable hook c³.
The slot 2 straddles the steel blade a¹, and in its normal or inoperative position
the hooked end of the blade is, by the action of a spring d, kept projected through
the slot a and elevated, as shown in Figs. 2 and 4.
The spring d has near one end a coil which is fitted over a stud d' extended from
the slide-bar B; the end 3 of the spring bearing against a part of said slide bar,
but the opposite free end of the spring is bent into the form of a circular loop d³,
one edge of which enters a notch d in the heel of the blade, the end of of the
spring near the loop resting against a shoulder a of the heel, said spring
serving to retain the said cutter in its normal forward position with its cutting
end out of the plane of the filling-end, and as herein shown elevated!
By removing the loop of the spring from the notch d', the cutter may be readily
removed to be cleaned, or oiled.
The cutter blade has suitable forward stop lugs 5, 5, to limit its forward position
under the action of the spring d, and it has a shoe 6 which slides on the bevelled
underside of the ear b, see Fig. 2, the cutter blade both sliding and rocking in
its movement as it must do to operate in accordance with this invention.
The shoe also receives the wear of the cutter and keeps the top side thereof from
being worn.
The temple at its front edge see Fig. 3, is cut or milled away each side the slot a
to leave a groove 8 to receive the filling-end when the cutter-blade acts on the
same to sever it, said groove. obviating any liability of the cutter-blade drawing
the said end into said groove a, during the operation of severing the end for the
cutting edge of the hooks are moved into the temple only substantially flush
with, the bottom of said groove, the edge of the steel blade a standing outside the
line of the bottom of the said groove.
The cutter blade is provided at its upper side with a projection 8, which as the
blade rises under the action of the spring d meets the bottom of the slot a*, in
the cap, see Fig. 4, thus preventing the slotted front end of the blade from striking
said cap and being battered or jammed to close the slot 2 in any way!

The blade has near its front end a notch 10 to embrace the stud by which the
toothed roller B5 is supported at one end.
elevated
In use the cutter blade herein shown will stand with its hooked' end
and removed for a distance from the front of the blade a" as represented in
Figs. 2 and 4.
As the lay comes forward at each beat, after filling has been thrown into the
shed, the lay strikes the heel of the cutter blade, which immediately causes the
hooked end to move from the position Figs. 2 and 4, placing the hook 3 of said
blade, behind the filling-end, provided there is such an end between the selvage
and the filling end holder described, and the said hooked end having caught the
filling end, the slight further movement of the lay forward causes the cutter blade
to be drawn into the temple head, drawing the filling end across the steel blade a¹
and severing the same at that point, this being done usually before the lay
carrying the reed meets the heel b³ of the temple to move the latter and the cutter
blade back for their full stroke.
The filling end is cut close to the selvage.
The time at which the cutter-blade operates is just before the reciprocation of
the temple, and it is also just before the regular running filling thread is beaten
in, and hence the cutter blade described cannot catch that thread, but is always
in position to operate upon the filling end extended from the selvage to the filling
end holder on the very first pick, serving it at such pick, so that the selvage is
left clean and, without any liability of being damaged by the filling end
In practice it has been found that the cutting mechanism shown severs the
thread before the temple is started back by the lay, but if for any reason the
threads should not be cut at this exact time, it will be cut while the temple and
cutter blade are being moved toward the breast beam together.
This invention is not limited to the exact shape shown for the cutter blade
and its hooks, and any cutter having hooks which may be put into position behind
the weft preparatory to cutting the same comes within the scope of this invention.
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:-
In a loom for weaving of the kind known as an "Automatic" loom.
1. A temple having a blade connected to it to act against one side of a filling
end, and a movable co-operating cutter blade which at its forward beat of the lay
is actuated to cut off the filling end between the said blades.
2. A reciprocating temple for use in a loom, said temple being provided with
a blade and having a co-operating blade shaped to be struck and moved to cut the
filling before the temple is reciprocated.
3. A reciprocating temple for use in a loom, said temple being provided with
a blade, and having mounted on it a second movable blade provided with a hook
to move into position between the filling end and the reed, and when moved toward
the breast beam of the loom with the reed cut off the filling end.
4. The use in a loom temple having an attached blade, of a co-operating movable
blade having a forked end provided with hooks, the said forked end straddling
the blade attached to the temple.
5. The use in a temple having a blade attached to it, of a sliding cutter blade
having a hook at one end and a heel at its opposite end, the latter blade being free
to be slid in or with relation to said temple.
6. The use in a temple having a blade attached to it, of a sliding cutter blade
having a hook at one end and a heel at its opposite end, the latter blade being free
to be slid in or with relation to said temple, and a spring to normally hold said
blade pressed toward the reed of the loom and with its hooked end elevated above
the plane of the filling-end.
7. A temple having a blade and presenting a space each side said blade, com-
bined with a sliding cutter having hook at one end and a heel at its opposite

page_text: and, said cutter being free to slide in or with relation to said temple, and having
at its upper side a projection to contact with the temple and prevent injury to the
slotted end of the cutter.
8. The use in a loom, of'a temple provided with two blades, one of which presents
a hooked end adapted to engage the filling end at its rear side, and means to move
said cutter vertically and slide the same in said temple during the cutting operation.
9. A temple, and a cutter, having a hooked end and free to be moved vertically
and to slide in said temple during the thread cutting operation, and a spring con-
nected to said temple and co-operating with said cutter, to normally keep the
cutter in its forward inoperative position.
10. A temple and its sliding thread cutter provided with a heel having a notch
and a shoulder, and a spring connected to said temple and shaped substantially as
described, whereby a portion of said spring may enter said notch, the end of the
spring engaging the shoulder of the heel.
