I HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature of
this invention to be as follows:-
My invention consists of a stop motion for a warping machine, formed of a thread
or yarn guide which is normally held in elevated position, and permitted to drop
when the yarn breaks said guide being in an electric circuit, whereby the dropping
of the same closes said circuit and causes the stopping of the machine.
It further consists of an annunciator or "tell tale," for indicating the location of
broken yarn.
According to my said invention the creels of a warping machine with the exception
of the features of my invention applied thereto, are of the usual construction.
Secured to the uprights of the frames of the creels are plates of copper or other
suitable metal which are connected with wires the latter being in communication with
a battery.
The yarn guides of the creels are pivotted to plates of copper or other suitable
metal said plates having connected with them wires and secured to the uprights and
having heels which are so disposed that when the guides are held in elevated position
by the yarn said heels are removed from the plates and when said guides are in their
lowermost position, the heels are in contact with said plates.
The shipper of the machine is connected with an arm which is pivotted to a suitable
part of the machine and engages with a clutch which is connected with the driving
shaft of the machine. On the loose. pulley of the clutch is an abutment which at a
certain time may be engaged by a metallic arm or finger which depends from a
proper part of the machine, and is pivotted thereto. Adjacent to the arm is a magnet
which is in an electric circuit, and adapted to attract said arm and place it in
position to engage with the abutment whereby owing to inclined faces of the
Price S1

page_text: contiguous parts of the clutch, the clutch is separated thus moving the arm and
operating the shipper whereby the machine will be stopped.
An index or arm, pivotted to a proper part of the machine is provided, and
adjacent to the finger, is a magnet which is in an electric circuit, and adapted to
attract said finger.
I employ as many fingers as I may have columns or spools in the creels, and may
locate all of the fingers in a suitable box for convenience of observation of the
operation of said fingers, this feature of my invention constituting an annunciator or
"tell tale," of the location of the broken yarn.
The operation is as follows:-
When the yarn is properly running from the spools of the creels to the desired
frame or take-up mechanism for making the warp, said yarn holds the guides raised.
Should however, the yarn break, the guide through which the same passes loses its
support by the yarn and drops, thus bringing the heel in contact with the relative
plate whereby the electric circuit is closed. The arm is now attracted by the magnet
and caused to strike the abutment whereby the clutch is operated, and the machine
stopped, in the inanner herein before stated.
Furthermore, the magnet of the column in which the broken yarn exists, attracts
the respective index whereby the movement of the latter indicates or announces the
location of the broken yarn, and the latter may receive proper attention, after which
the fallen guide is raised by the yarn as united, and thus the heel is withdrawn from
the plate the circuit then being again broken. The parts now assume their normal
positions, and the machine is again started.
The yarn guides are preferably located close to the spools, so as to cause prompt
action of the stopping mechanism of the machine.
The guides may be adapted to slide in bearings on plates of the crcels, whereby the
heel or heel ends of the guides when the latter drop may come in contact with
shoulders on the plates or with the ends of the plates themselves, if so desired, and it
is evident that the heels may be dispensed with in either case, so that the guides may
come directly in contact with the plates or shoulders thereon.

Improvements relating to Warping Machines.
I HENRY HARRIS LAKE of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, 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:-
This invention consists of a stop motion for a warp machine formed of a thread or
yarn guide which is normally held in elevated position, and permitted to drop
when the yarn breaks, the said guide being in an electric circuit, whereby the
dropping of the same closes the said circuit and causes the stopping of the machine.
It further consists of an annunciator or "tell tale" for indicating the location of
broken yarn.
In the accompanying drawings
Figure 1 represents a side elevation of a stop motion for a warping machine with
the improvement shown in diagrammatic view.
Figure 2 represents a top or plan view thereof.
Figure 3 represents a side elevation of a detached portion thereof drawn to an
enlarged scale.
Figure 4 represents a top view of the parts shown in Figure 3.
Figure 5 represents a side elevation of a detached portion drawn to an enlarged
scale.
Figure 6 represents a top view of the parts shown in Figure 5.
Figures 7 and 8 represent side elevations of a modification.
Similar letters of reference indicate corresponding parts in the several figures.
A represents the creels of a warping machine, which excepting the features of my
invention applied thereto, are of usual construction.
Secured to the uprights B of the frames of the creels are plates C of copper or
other suitable metal which are connected with wires D, the latter being in communi-
cation with a battery E.
Frepresents the yarn guides of the creels, the same being pivoted to plates F¹ of
copper or other suitable metal, the said plates having connected with thein wires D¹
secured to the uprights B, and having heels G which are so disposed that when
the guides are held in elevated position by the yarn the said heels G are removed
from the plates C, and when the said guides are in their lowermost position, the
heels Gare in contact with the said plates.

page_text: The plates F¹ to which the guides F are pivoted are all connected electrically by
wires 1) to a common wire D3 passing through the magnet P near the stop motion,
and thence to one pole of the battery E, while the plates are connected similarly
to another wire D running to the other pole of the battery.
In other words, the plates C and F are all in normally open multiple arc circuits
between the wires D³ and D₁ and each of such multiple arc circuits contains an
indicator magnet R for operating a tell tale pointer Q.
H represents the shipper of the machine, the same being connected with an arm J
which is pivoted to a suitable part of the machine, and engages with a shipper
sleeve K having free longitudinal motion on the shaft L, but rotatable therewith
by means of a spline. Lateral movement is given to this sleeve and to the arm J
through the agency of the bevel sleeve K which is loosely mounted on the shaft L
and provided with the abutment M adapted to be engaged at certain times by the
pivotted arm M depending from the machine.
The adjacent ends of the said sleeves K and K' are cut obliquely or formed with
cam contact surfaces so that when the said sleeve K is engaged by the said arm N
the said sleeve K is pushed outwardly.
Adjacent to the arm N is the magnet P which is in the electric circuit and adapted
to attract the said arm N'and place it in position to engage the said abutment M
and thus stop the said sleeve K' from rotating, whereby owing to the inclined or
cam contact faces of the sleeves, the outer one or K is moved laterally outward,
thereby moving the arm J and shipper H, and thus shifting the driving belt, so that
the machine will be stopped.
R, R are a series of electro-magnets each located in a separate multiple arc
branch running from the plates C, F, in circuits D' and adapted to actuate indicators
pointers or armatures Q, as will be explained hereafter.
I may employ as many fingers as I may have columns of spools in the creels,
the magnets operating the said fingers being placed in contact with either the
wires D or D and I may locate all of the fingers in a suitable box for convenience
of observation of the operation of the said fingers, this feature of my invention
constituting an annunciator or "tell tale" of the location of broken yarn.
The construction and relative arrangement of each finger and its magnet, being
similar to that shown in Figures 1 and 4, a figure illustrative of the series is
therefore not inserted in the drawings.
The operation is as follows:
When the yarn is properly running from the spools of the creels to the desired
frame or take-up mechanism for making the warp, the said yarn holds the guides F
raised, as shown at the top of Figure 3. Should however the yarn break the
guide through which the same passes, loses its support by the yarn and drops,
thus bringing the heel G in contact with the relative plate C, see bottom of
Figure 3, whereby the electric circuit is closed. The arm N is now attracted by
the magnet P, and caused to strike the abutment M, whereby the sleeve K is
operated, and the machine stopped in the manner hereinbefore stated.
Two pulleys, one loose and the other fixed to the shaft in a manner well under-
stood, are shown in Figure 2, with a belt and a well known form of belt
shipper H.
Furthermore the magnet R of the column in which the broken yarn exists,
attracts the respective index Q, whereby the movement of the latter indicates or
announces the location of the broken yarn, and the latter may receive proper
attention after which the fallen guide is raised by the yarn as united, and thus
the heel G is withdrawn from the plate C, the circuit then being again broken.
The arm J now being operated by hand so as to shift the belt to the fast pulloy,
the sleeves K and K' are also restored to their normal positions, and the machine
is again started.
It will be seen that the yarn guides are located close to the spools, so as to
cause prompt action of the stopping mechanism of the machine.

page_text: In Figures 7 and 8, the guides are shown as adapted to slide in bearings on
plates of the creels, whereby the heels or heel ends G of the guides when the
latter drop may come in contact with shoulders on the plates C, or with the ends
of the plates themselves if so desired, and it is evident that the heels G may he
dispensed with in either case, so that the guides may come directly in contact with
the plates C or shoulders thereon.
