PROVISIONAL SPECIFICATION left by the said George Francis Bradbury
and Henry Lomax at the Office of the Commissioners of Patents on the
7th December 1878.

BEAMING OR WARPING YARN OR THREAD."
"
This Invention relates to an improved apparatus for bringing the knocking off
mechanism into operation when an "end" or thread is broken, and also for indi-
cating the particular "end" or thread so broken.
The "faller" pins or other like devices used heretofore, stopping the machine
when an "end" is broken, have had the defect that the particular end'or thread
broken is not indicated, and that where more than one end is down or broken, the
machine is started and stopped repeatedly before the cause is detected.
According to this our Invention, we employ devices so constructed that the one
end serves as a guide or passage for the "end" or thread, the other end is counter-
balanced, and when the "end" or thread breaks one extremity of the device falls,

page_text: the other tilts upwards and signals the exact position of the end or thread that is
broken. The devices are mounted upon a shaft or axis on which they are free to
tilt or move, and have a catch piece or other projection on which the vibrator or
other appliance connected to the knocking off mechanism acts.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said George Francis Bradbury and Henry Lomax in the Great Seal Patent
Office on the 6th June 1879.

"IMPROVEMENTS IN MACHINERY FOR
BEAMING OR WARPING YARN OR THREAD."
This Invention relates to an improved apparatus for bringing the "knocking off"
mechanism into operation when an "end" or thread is broken, and also for indi-
cating the particular "end" or thread so broken.
The faller" pins or other like devices used heretofore, stopping the machine
when an "end" is broken, have had the defect that the particular end or thread
broken is not indicated, and that when more than one end is down or broken, the
machine is started and stopped repeatedly before the cause is detected.
According to this our Invention, we employ devices so constructed that the one
end serves as a guide or passage for the "end" or thread, the other end is counter-
balanced, and when the "end" or thread breaks one extremity of the device falls;
the other tilts upwards and signals the exact position of the end or thread that is
broken. The devices are mounted upon a shaft or axis on which they are free to
tilt or move, and have a catch piece or other projection on which the vibrator or
other appliance connected to the "knocking off" mechanism acts.
Such being the nature and object of this our said Invention, we will now describe
the same in detail, and in order that the Invention may be fully understood, have
hereunto annexed a Sheet of Drawings illustrative thereof, and have marked the
same with figures and letters of reference, the same letter indicating a like part in
both views. Fig. 1 is a side elevation of our improved apparatus; Fig. 2 is a plan
view.
At A is the device so constructed that its end B serves by the curve C to act as a
guide or passage for the "end" or thread D, the other extremity E of the faller
device is counterbalanced by the extra weight of the thread guide end, that when
the hook of the device falls and the other end E tilts upwards and signals the exact
position of the end or thread that is broken. The devices A are mounted upon the
shaft or axis G on which they are free to tilt or move as described, and the hooked
catch piece or other projection is caught by the ordinary vibrating bar H; the
latter draws the devices A, A, and their carrying axis G forwards, and by the arm

page_text: "
J knocking off the spring stop handle K. When more than one "end" or "thread "
is "down or broken at the same time, should the machine be started without taking
up all broken ends, the device or devices A that are still engaged with the vibrator
will again cause the machine to knock off so that the beaming cannot proceed until
all the ends are up. In order to admit of a large number of the devices A being
mounted on one shaft, each alternate device is made as shewn at Fig. 2 longer than
the other, that the guide or foulded ends may be clear. of the next nearest device.
Having thus fully described the nature and particulars of this our said Invention,
together with the manner in which the same is to be or may be performed or carried
into practical effect, we would have it understood that what we claim is,-
"
Firstly. The use of the devices A, one end serving as a guide for the thread or
end," and also engaging with the vibrator, its other end serving to signal or indi-
cate the position of the thread or "end" down or broken.
Secondly. The combination of the device A with moveable axis G and arm J for
knocking off as described and substantially as illustrated.
In witness whereof, we, the said George Francis Bradbury and Henry
Lomax, have hereunto set our hands and seals, this Second day of June,
in the year of our Lord One thousand eight hundred and seventy nine.
