Warnsdorf, Bohemia, in the Empire of Austria, Model Maker and Engraver
respectively.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6, Lord Street. Liverpool and 6 Bank Street, Manchester
both in the County of Lancaster and 323 High Holborn in the County of Middlesex,
Civil Engineer, do hereby declare the nature of this invention to be as follows
The breaking of threads in looms frequently happens when the shuttle traps, in
spite of the arrangement of the loose sley. Now this invention has for its object
an apparatus or device which will, if the shuttle traps, automatically and
instantaneously stop the loom.
The manner in which this is accomplished will be understood from the following
description, reference being had to the accompanying drawings, in which,
Figure 1 is an elevation of a portion of the apparatus or device,
Figure 2 a view partly in section taken at right angles to Figure 1,
Figure 3 a detail of the hinged arm hereinafter described,
Figure 4 a general view, on a reduced scale, of the complete apparatus with a
portion of the loom frame and such parts of the mechanism as are necessary to show
the invention clearly.
In these-
K is a box attached to the standard A' of the loom frame by means of screws k,
and A is a winged piece hinged at 1 and to this box and carrying lugs or
projections a¹ a². R is a roller carried by a forked arm G mounted on the axle d
of the lathe frame S, Figure 4. As long as the loom works regularly, the roller R
passes constantly to and fro under the shoulder m formed on the hinged piece A
and is inoperative, but if, from any cause, the shuttles should trap in the shed and
the sley or lea B', Figure 4, spring out, the arm L would operate the axle d and
levers G, causing the latter, with the roller R, to be raised in the direction of the
arrow (shown in Figure 4). The roller in its travel comes in contact with the
shoulder m of the hinged piece A and turns the latter in the direction of the loom
standard A', causing the arm a' of the hinged piece A to engage the lever B,
Figures 1 and 2, and turn it on its pivot b³, thereby turning the elbow lever C on
its pivot and withdrawing the projection n.
The elbow lever is normally held in the position shown in Figures 1 and 2 by
means of a spring F³, and the projection n of the said lever engages a stud or
projection f on the buffer arm P, and holds it in the position shown in Figures 1
and 2, but if the projection n be withdrawn, as aforementioned, the buffer arm P
will be thrown down by the spring F' against the warp beam as shown in Figure 4,
the said buffer arm being provided at its end with india rubber K' to moderate the
shock when it strikes the lathe block L. The lathe is at once arrested. At the
same time, the projection a' on the hinged piece A. has come in contact with an
arm P' mounted on a spindle w, Figure 4, and forced it in the direction of the
arrow, thus rotating the spindle, which is connected at its other end by means of a
cam with the shootguard and disengaging rod, and throwing off the belt in the
usual manner so that an immediate stoppage of the entire mechanism takes place.

Improved Apparatus or Device for Automatically and Instan-
taneously Stopping Looms when the Shuttle Traps.
A communication by HERMANN EGER and JOHANN ANTON RICHTER, both of
Warnsdorf, Bohemia, in the Empire of Austria, Model Maker and Engraver
respectively.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool, and 6, Bank Street,
Manchester, both in the County of Lancaster, and 323, High Holborn, in the
County of Middlesex, Civil Engineer, 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 :-
The breaking of threads in looms frequently happens when the shuttle traps, in
spite of the arrangement of the loose sley, especially when working with several
shuttles. Now this invention has for its object an apparatus or device which will,
if the shuttle traps, automatically and instantaneously stop the loom and thus
prevent snch breakages.
The manner in which this is accomplished will be understood from the following
description, reference being had to the drawings filed with the Provisional in
which,
-
Figure 1 is an elevation of a portion of the apparatus or device,
Figure 2 a view partly in section taken at right angles to Figure 1,
Figure 3 a detail of the hinged arm hereinafter described,
Figure 4 a general view, on a reduced scale, of the complete apparatus with a
portion of the loom frame and such parts of the mechanism as are necessary to show
the invention clearly.
In these:-
K is a box attached to the standard A' of the loom frame by means of screws k
and A. is a winged piece hinged at and to this box and carrying lugs or
projections a a. R is a roller carried by a forked arm G mounted on the axle d
of the lathe frame S, Figure 4. As long as the loom works regularly, the roller R
passes constantly to and fro under the shoulder m formed on the hinged piece A
and is inoperative, but if, from any cause the shuttles should trap in the shed and
the sley or lea B¹, Figure 4, spring out, the arm L would operate the axle d and
levers G, causing the latter, with the roller R, to be raised in the direction of the
arrow (shown in Figure 4). The roller in its travel comes in contact with the
shoulder m of the hinged piece A and turns the latter in the direction of the loom
standard A¹ causing the arm a² of the hinged piece A to engage the lever B,
Figures 1 and 2, and turn it on its pivot b³, thereby turning the elbow lever C on
its pivot and withdrawing the projection n.
The elbow lever is normally held in the position shown in Figures 1 and 2 by
means of a spring F, and the projection n of the said lever engages a stud or
projection on the buffer arm P, and holds it in the position shown in Figures 1
and 2, but if the projection n be withdrawn, as aforementioned, the buffer arm P
will be thrown down by the spring F₁ against the sley as shown in Figure 4,
the said buffer arm being provided at its end with india rubber K' to moderate the
shock when it strikes the lathe block L'. The lathe is at once arrested. At the
same time, the projection a¹ on the hinged piece A has come in contact with an
arm P¹ mounted on a spindle w Figure 4, and forced it in the direction of the arrow,
thus rotating the spindle, which is connected at its other end by means of a cam
with suitable parts for throwing off the belt in the usual manner so that an
immediate stoppage of the entire mechanism takes place.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is :-
An improved safety device for guarding against the shuttle trapping when the
sley springs out, in which device a buffer P, released by means of a lever L together
with a ruller R, winged piece A, projection a', levers B and C with projection n
and stud is opposed to the approaching lathe, and will arrest the sley for the
purposes described.
