TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
BROOKES, of 62, Chancery Lane, London, in the County of Middlesex, .
Patent and Registration Agent, send greeting.

page_text: WHEREAS I am in possession of an Invention for
"IMPROVEMENTS
IN MEANS FOR STOPPING THE WORKING OF APPARATUS ON THE BREAKING OR
FAILURE OF THREAD IN THE ROVING, SPINNING, OR TWISTING OF WOOL, COTTON,
OR OTHER FIBRES," being a communication to me from abroad by the
Augsburger Kammgarnspinnerci, of Augsburg, in the Kingdom of
Bavaria, and have petitioned Her Majesty to grant unto me, my
exccutors, administrators, and assigns, Her Royal Letters Patent for the
same, and have made solemn Declaration that it has been communicated
to me as aforesaid.
NOW KNOW YE, that I, the said William Brookes, do hereby
declare that the following Complete Specification, under my hand and
scal, fully describes and ascertains the nature of the said Invention,
and in what manner the same is to be performed in and by the following
statement, reference being had to the Drawings hercunto annexed, and
to the letters and figures marked thereon (that is to say) :-
The Invention relates to the use of an electro-magnetic regulator
for stopping the motion of apparatus on the breaking or failure of any
of the threads in the roving, spinning, or twisting of wool, cotton, or
other fibres.
'

page_text: d.) The cylinder of the machine will be no more broken or bent,
and the spiked roller (where such is in use) will no more be ruined.
e.) The waste occurring formerly through the undisturbed twisting is
avoided.
And f) The production of the machine is increased.

page_text: wooden blocks k, k. The two projecting magnet portions are screwed
into a metal plate with two adjusting screws h, h¹, which carry at their
points the grappling iron f. The latter is opposite to the magnet
provided with a small plate constructed of soft iron, and at the other
end with a steel wedge g. A weak spring p presses the grappling iron
into the rest in the metal angle o. On the entrance or feeding cylinder
of the machine is fixed a double excentric m, which by cach revolution
of the feeding cylinder is enabled to raise the tongue c of the angle b
(which tongue sits moveably on a small pivot) twice, and allows the
same to fall again. The chain & passes over the pulley d and carries
at one end by means of a hook ₺ (provided with a long slit) a weight
(of about 4 or 5 kilogrammes), and at the other end is fastened to
- the rod q running along the machine, and which by means of the
lever communicates with the rod q', which also runs alongside the
machine, and which carry the fork found above the strap drums of the
machine, for the purpose of bringing the machine in motion or to stop

the head of the machine proceeds an isolated copper wire and conducts
to the positive pole of the same galvanic battery.

III: The Thread Protector .and Current Closer: by the Exit of the
Doubled Thread before the Reeling of the same, Figures 1, 2,-6, and 7.
-In front of the spooling cylinder of the roving machine and running
the entire length of the same is an iron rail C, which carries the
trumpets of the entering threads. To this rail C by cach trumpet is
affixed by means of a metal pivot a brass thread protector x, which at
its longest end rests on the respective thread and can easily revolve on
its pivot until the tail lays itself on the (in porcelain capsules isolated)
brass wire which runs along the machine, through which the thread
protector operates as current closer. As the rail C is in communication
with the machine it forms a conductor to the negative pole of the
battery and through the electro-magnets after the manner as already
described in II. From the wire ¹ proceeds from the top of tho
machine an isolated copper wire to form the communication with the
copper wire described in II., which conducts to the positive pole of the

page_text: communication of the rod g with the chain s the weight G is wound up,
and the perpendicular leg of the angle & falls through the weight of the
horizontal leg down over the end of the segmente as it passes by and
lays itself on near the pulley d, through which the wound up weight
is unable to descend. The break is free, the thread protectors u and a
at the entrance and exit passages rest on the threads of the machine, the
galvanic current is intercepted, the grappling iron fis at rest (Fig. 5),
the double excentric m moves the tongue c constantly up and down.
If a doubling thread now breaks at entering the respective thread
protector is freed and falls by reason of its own weight backwards,
and thus comes with its tail in communication with the brass band v
(Fig. 9), through which current from the galvanic battery is closed.
The magnets 1, 1, draw the grappling iron towards them, and as soon
as the tongue e falls downwards the wedge g slips between the tongue c
and the angle (Fig. 3), the next following nose of the double
excentric m lifts the tongue c, and this again lifts the horizontal leg
of the angle by means of the pushed in wedge g, at the same time
however the perpendicular leg of the angle moves back again, the
segment e and the chain pulley d are freed, and the weight G by means
of the hook t, chain 8, and rods q, q', draws immediately the driving
straps on to the loose strap drums of the machine. Somewhat twenty
millemetres however before the weight has arrived at the end of its
chain the slit hook comes to sit on the nose of the beam y which is
thus drawn away, the breaks presses on the fly wheel E and the machine
stands instantly still.
2. Function by Exit of the Doubled Threads before they are Spooled.-
The machine is set in motion in the manner as above described; should
however through a twisting in the interior of the machine a thread
remain out, or if the same breaks before the reeling cylinder, the longest
portion of the thread protector a falls instantly through its own weight

page_text: Having thus described the Invention as communicated to me, I would
have it understood that what I claim is the arranging or combining
parts whereby the stoppage of the working of the apparatus is effected
on the breaking or failure of any of the threads under operation by
electrical action, substantially as described.
In witness whereof, I, the said William Brookes, have hereunto
set my hand and seal, this Twenty-second day of August, in the
year of our Lord One thousand eight hundred and seventy-two.
