I EDWARD SMITH, Manufacturers Agent, of 8 Brook Street, Bradford, in tho
County of Yorkshire do hereby declare the nature of this invention to be as
follows:-
:-
Improvements on my Invention for "An Automatic motion for Stopping the action
of a Loom when any of the Warp threads break;" described in Specification
No. 53984, and will be understood by reference to the Drawings accompanying that
Specification.
1st. The Catches B, B', are provided with a Slot hole instead of the small round
hole, in order to hang them on the round wire in the reed; the rod B² preventing
them from flying out in working-They are also provided with one or more holes in
their broad or lower extremity in order to receive fastenings from a nose bit of metal
clamped over such broad extremity, this nose bit being also provided with projections
to form the dent for the warp thread to enter.
2nd. As a substitute for the rod supports "P," I provide the top beam of the reed
with what I preferably term a flanged reed cap, which is made of two strips of metal
which I designate flanges, running parallel to each other on either side of the reed,
and immediately under the top beam of the reed, and held in position pressed slightly
to the reed by means of strips of sheet steel or other metal fixed to them at short
distances, such strips being bent to the shape of, and fitted over, the top beam of the
reed-Bits of metal are rivetted or bolted to the flanges of this reed cap to keep the
rod "B," in position. The flange at the back of the reed I make broad enough for
the sloped ends of the catches "B, B1, to rest against, thus doing away with the
necessity of the flat wire passed through the oblong holo "A" in the wires
of the reed, and also doing away with the necessity of the oblong hole A¹,
"A" in tho
and thus rendering it easier to make the little round hole
wires of the reed by means of a punch and Die, fixed between the wire
delivery drum and the feed pulleys of the ordinary reed-making machine.

page_text: To the flango at the back of the reed are attached the fixed parts of the
hinge by which the rod "C" works, thus avoiding the necessity of driving
supports "P" into the beam of the reed-When the warp is woven out, this reed cap
with its fittings is slotted off, and the guard (Figs. 8 and 9) is slotted on in its
place.
3rd. As a substitute for the rod attachment "H" I provide the rod attachment "D"
with a fixed projection. For weaving broad fabrics an attachment liko "D" is fixed
to the other end of rod "C" and is operated in the same way and at the samo moment
"D."
as
4th. Instead of the support "Q" for the spiral spring "G," I leave spaces in the
hinge and introduce one or more spiral springs on the connecting wire "C" the loose
end of such springs bearing on and turning the rod "C."
5th. The top end of the piece of metal "R" is rivetted or bolted to the flanged
reed cap for fast reel looms; but for loose reed looms it is hinged.
6th. Instead of the swivel-catch "KL" I use a balanced lever, one end of which
points towards the rocking frame and is made with an incline in such a manner that
when the rod "C" has been dropped close to the reed, the fixed projection on "I)"
clears the bottom of the incline on the advance of the reed; and the rod "C" having
been turned up by "I" on to the support "E" the said projection clears the top of
the incline when the reed recedes; but when a warp thread is broken the fixed
projection on "1" strikes tho incline of the balanced lever, thus forcing it down and
throwing the other end of it upward; this in turn operates an Llever to which is
attached a small rod by means of which, a finger-like point (which works on a centre
and is provided with a slot-hole, and a small spring to keep it in position) is brought
into a position, straight with the knock-off handle and a small piece of metal fixed to
the rocking-frame-At the moment when the finger-like point has been turned, tho
small piece of metal on the rocking frame strikes one end of it and drives the other
end of it against the knock-off handle, thus forcing it out of its notch and by this
means throwing the belt on to the loose pulley and arresting the motion of tho loom.
7th. In pushing the handle out of its notch in this manner, the brake is not applied
in the ordinary way-I therefore despense with the projection from the casting fo
which the weight lever of the brake is attached, thereby allowing the brake to act
directly on the brake-wheel in every case, immediately the handle is pushed out of its
notch To enable the weaver to take the brake off in order to work the loom by hand
I pivot a support-catch on the knock off handle in such a position, that when the
handle is pushed out of its notch, the said support-catch, clears the weight lever of the
brake; and in order to take the brake off, the weaver lifts the weight lever and the
catch falls forward and supports it.

Improvements on my Invention for "An Automatic Motion for
Stopping the Loom when the Warp Thread Breaks," Patent
No. 5398, 1884.
I EDWARD SMITH, Manufacturers Agent, of 8 Brook Street, Bradford, in the
County of Yorkshire, 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 :-
1st. The catches B3, B₁ are provided with a slot hole in order to hang them on tho
round wire in the reed the rod B² preventing them from flying out when working.
They are also provided with one or more holes in their broad end in order to receive
fastenings from a nose bit of metal clamped over such broad end, this nose bit being
provided with projections to form the dent for the warp thread to enter.
2nd. As a substitute for the rod supports PI provide the top beam of the reed with
what I preferably term a flanged reed cap which is made of two strips of metal which
1 designate flanges, running parallel to each other on either side of the reed imme-
diately under the top beam of the reed, and held in position, pressed slightly to the
reed by means of strips of sheet steel or other metal, which are bent so as to fit over
the top beam of the reed and are soldered or rivetted at short distances from each
other to the said flanges-The end of the said strips of metal which is attached to the
flange at the back of the reed as it appears in the loom is bent round so as to form
the supporting part of the hinge by which the rod C, C' works. The sloped ends of
the catches B, B rest against the bottom part of the said flange at the back of the
reed, thus doing away with the necessity of the flat wire and the oblong hole A' in
the wires of the reed. When the warp is woven out this reed cap with its fittings is
slotted off and the guard (Figs. 8 and 9) is slotted on.
3rd. As a substitute for the rod attachment H I provide the projection D with a
fixed finger-like point. For weaving broad fabrics I fix a projection like D to the
other end of the rod C and operate it in the sume way and at the same moment
as D.
4th. Instead of the support Q for the spiral spring G I introduce one or more
spiral springs on to the connecting wire C the loose end of such springs bearing on
and turning the rod (
5th. The top end of the piece of metal R is rivitted or bolted to the flanges of
the reed cap for fast reed looms, but for loose reed looms it is hinged to the said
flanges.
6th. Instead of the swivel catch L and its projection K I use a balanced lever one
end of which is provided with a curved projection. This balanced lever is supported
by a casting fixed in any suitable manner to the loom frame and is fixed so that when
the rod has been dropped close to the reed the finger-like point- on D clears the
bottom edges of the curved end of the balanced lever on the advance of the reed and

page_text: the rod C having been turned up by I onto the support catch E the said finger-like
point on D clears the top of the said curved end when the reed recedes.
When a warp thread is broken the finger-like point on D strikes the curved end of
the said balanced lover, on the advance of the reed, thus forcing it down and throwing
the other end of it upward and in so doing raising an arm of an lever, to the other
arm of which a small rod is attached, by means of which a piece of metal which I
designate a pusher, is brought into a position straight with the knock-off handle and
a piece of metal, fixed opposite to the knock-off handle, on the rocking frame of
the loom.
This pusher is provided with a slot hole through which is passed a pin, which is
fixed into a casting, the said casting being fixed in any suitable manner to the loom
frame. One end of a small spring is attached to the said pusher and the other end
to the casting, in order to return tho pusher to its normal position after it has been
operated. At the moment when the pusher has been operated, the rocking frame
advancing, the small piece of metal attached to it strikes one end of the pusher and
drives the other end of it against the knock-off handle, thus forcing it out of its
notch, and by this means throwing the belt on to the loose pulley and thus arresting
the motion of the loom.
7th. In pushing the handle out of its notch in this manner, the brake is not applied
in the ordinary way.
I therefore dispense with the projection of the casting to which the weight lever of
the brake is attached, which rests on the weft fork lever, thereby allowing the brake
to act directly on the brake wheel in every case, immediately the handle is pushed
out of its notch.
To enable the weaver to take the brake off in order to work the loom by hand, I
pivot what I preferably call a brake lever support-catch, on to the knock-off handle,
in such a position that when the handle is pushed out of its noich, the said support-
catel clears the weight lever of the brake; and in order to take the brake off the
brake wheel, the weaver lifts the weight lever on to the said support-catch.
In order to enable my improvements to be fully understood I will proceed to describe
them by reference to the accompanying drawings.

support-catch when the brake is on the brake wheel.
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) In an automatic motion for stopping the action of a loom upon the breaking
of a warp thread the use of the slot hole in the catch in order to hang it on the wire
in the reed, and the use of one or more holes in the catch to receive fastenings from
a bit of metal put on it to form the dent for the warp thread to enter as hereinbefore
described and represented in the accompanying drawing.
(2) In an automatic motion for stopping the action of a loom upon the breaking of
a warp thread the use of the flanged reed-cap for supporting the working rod, and
also for the top ends of the catches to rest against substantially as and for the
purposes hereinbefore described and represented in the accompanying drawing.
(3) In an automatic motion for stopping the action of a loom upon the breaking
of a warp thread the use of the balanced lever operating in combination with a fixed
point on the rod-projection and the ✓ lever substantially as and for the purposes
hereinbefore described and represented in the accompanying drawing.
(4) In an automatic motion for stopping the action of a loom upon the breaking
of a warp thread the use of the lever and the rod connected to it, operating in
connection with the balanced lever for bringing the pusher into a position straight
with the knock-off handle and the piece of metal on the rocking frame for the purposes
hereinbefore described and represented in the accompanying drawing.
() In an automatic motion for stopping the action of a loom upon the breaking of
a warp thread the use of the pusher operating in connection with the lever and the
piece of metal fixed to the rocking frame of the loom for the purpose of forcing the
knock-off handle out of its notch as hereinbefore described and represented in
the accompanying drawing.
(6) The brake lever support-catch for enabling the weaver to work the loom by
hand as hereinbefore described and represented in the accompanying drawing.
