We HENRY HOBSON TANKARD of Upper Croft Mill Bowling near Bradford in the
County of York, Worsted Spinner, and HERBERT WILLIAM BROADBENT of No. 155
Birch Lane Bowling before mentioned, Overlooker do hereby declare the nature of
this invention to be as follows:-
This invention relates to means or apparatus for regulating the production of yarn
or "doffings" in spinning woollen, worsted or other yarns by means of a self acting
device capable of stopping the machine at the proper time for each doffing; of
indicating the number of doffings effected and of stopping the machine when a
set
"
or prearranged number of "doffings" has been effected, by enabling the overlooker
or other person to set the regulating device at will to stop after a prescribed number
of doffings have taken place and it is necessary for the device to be reset before the
frame can be restarted.
By these means the control of the overlooker is secured and facilitated and the pro-
duction through inattention or otherwise of too many "doffings" or too great a
quantity of yarn is prevented.
The apparatus is constructed substantially as follows. On one end of the spinning
frame is applied a double armed catch piece swinging on a centre and taking at one
of its ends into a recess or equivalent means in a wheel mounted on a spindle
operating the throw off mechanism to stop the frame. The opposite or other end of
this catch is caught under and retained by a disc escapement or retaining plate or
piece which rotates with the axis on which it is mounted, until the end of the catch in
the rotation of the plate arrives at a place where the plate or disc is cut away or slotted
when the catch swings round releasing the throwing off wheel and permitting it to be
rotated until the frame is stopped by means of a cord or band spirally wound at one
end on that axis and having a weight slung thereto at its other end. This axis carrying

page_text: the disc with the escapement passes down through and rests with capability of rising
in bearings affixed to the frame and at its lower end it carries a tooth wheel which
gears with another tooth wheel mounted on another axis also carried in suitable
bearings and having on it another tooth wheel which is operated by a worm wheel
mounted on a driving shaft driven in accord with the driving of the frame spindles.
On the disc rod is mounted a worm wheel which gears into a toothed indicating
wheel capable of rotating on a centre or stud affixed to the framing and having also
mounted thereon a fixed indicating finger
The operation of the apparatus is as follows:-At the completion of each "doffing"
or filling of a bobbin by the desired extent of winding the throwing off wheel is
permitted to rotate once by the escapement disc permitting the catch to release
throwing off wheel. Also the worm advances the toothed recording wheel one tooth
which is indicated by the pointer and so on until the desired number of doffings have
been made when the recording wheel having completed its travel a pin thereon engages
the fixed pointer and the toothed wheel becomes a fixture, upon which the rod con-
tinuing to rotate, the worm continuing to travel mounts on the teeth of the record
wheel raising the rod and lifting its surmounting disc free of the catch and releasing
the throwing off wheel and permitting the immediate stoppage of the spinning frame
until the overlooker or other person resets the regulating device.
Although in the foregoing description of the application of the invention we have
more particularly described it as in connection with a cap frame, the improvements
are applicable to fly frames and to mule spinning machines by slight modifications in
the connecting parts.
By means of this invention when applied to cap or to fly frames or to mule spinning
machinery the uniformity of production of "doffings" or quantities of windings of
yarus on the bobbins or spools can be regulated to a great nicety with essential
beneficial results in the subsequent operations of doubling.

Improvements in Means or Apparatus for Regulating and Indicating
the Production of Yarn or "Doffings" in Spinning Woollen,
Worsted, Alpaca, Mohair, and other Yarns, and in Doubling the
same.
We HENRY HOBSON TANKARD of Upper Croft Mill Bowling near Bradford in
the County of York, Worsted Spinner, and HERBERT WILLIAM BROADBENT of
No. 155 Birch Lane Bowling before mentioned, Overlooker, 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 relates to means or apparatus for regulating the production of yarn
or "doffings" in spinning woollen worsted or other yarns by means of a self acting
device capable of stopping the machine at the proper time for each doffing; of
indicating the number of doffings effected and of stopping the machine when a set
or prearranged number of "doftings" has been effected by enabling the overlooker or
other person to set the regulating device at will to stop after a prescribed number of
doffings have taken place and it is necessary for the device to be reset before the
frame can be restarted.
By these means the control of the overlooker is secured and facilitated and the
production through inattention or otherwise of too many "doffings" or too great a
quantity of yarn is prevented.
The apparatus is constructed substantially as follows:-On one end of the spinning
frame is applied a double armed catch piece swinging on a centre and taking at one of
its ends into a recess or equivalent means in a wheel mounted on a spindle operating
the throw off mechanism to stop the frame. The opposite or other end of this catch
is caught under and retained by a disc escapement or retaining plate or piece which
rotates with the axis on which it is mounted, until the end of the catch in the rotation
of the plate arrives at a place where the plate or disc is cut away or slotted when the
catch swings round releasing the throwing off wheel and permitting it to be rotated
until the frame is stopped, by means of a cord or band spirally wound at one end on
that axis and having a weight slung thereto at its other end. This axis carrying the
disc with the escapement passes down through and rests with capability of rising in
bearings affixed to the frame and at its lower end it carries a tooth wheel which gears
with another tooth wheel mounted on another axis also carried in suitable bearings
and having on it another tooth wheel which is operated by a worm wheel mounted on
a driving shaft driven in accord with the driving of the frame spindles.
On the disc rod is mounted a worm wheel which gears into a toothed indicating
wheel, having its teeth numbered in series and carrying a stopping pin capable of
rotating on a centre or stud affixed to the framing and having also mounted thereon
a fixed indicating finger, against which the stopping pin carried by the toothed
indicating wheel comes in contact at the completion of the desired extent of rotation
of the numbered toothed indicating wheel.

page_text: Figure 1 shews one end of a spinning frame, a being the framing of the machine,
b the throwing off wheel the revolution of which operates to effect the stoppage of
the machine and a handle thereon.
Figure 2 is a view taken at right angles to Figure 1 and shewing the same in
section.
Figure 3 is a view of the upper side of the disc D separately.
Figure 4 is an underside view of the same and Figure 5 is an edge view thoreof.
The under edge of the disc D is of diminishing thickness or is inclined from
(1) to (2).
This
A is a worm wheel mounted on a shaft A¹ carried in suitable bearings and driven
by and in accord with the power driving the spindles as may be found most con-
venient, and this wheel A engages with and drives the inclined tooth pinion B mounted
on the same axis as and rotating the smaller tooth pinion B¹, which axis and these
pinions borne thereby are carried by the bracket B2 attached to the framing a.
wheel B engages a change wheel mounted on the lower end C2 of the vertical
axis C, upon the upper end of which is mounted the slotted disc or cam plato D.
E is one end of a swing lever centred at E and having its opposite end F engaged in
a recess or catch in the throwing off wheel b, whilst its other end E is retained under
the plate D.
His a toothed indicating wheel the teeth arranged on its periphery being taken
into by a worm wlieel M mounted on the axis C. On the face of this wheel H are
marked divisions which answer to the number of divided notches on the periphery
and correspond with the number of doffings that may be effected before the machine
is stopped.
This number of the teeth in operation or number of doffings effected is varied by
change of position of the indicating wheel H as for example supposing six doffings
are to be effected the said wheel H will be set with the tooth correspondingly
numbered 6 in position behind the fixed index finger and for each revolution of the
rod CC numbers 5, 4, 3, 2 would be successively indicated and 1 being the stop pin
tooth the position of the tooth 1 with the stop pin against the index finger would bring
about the stoppage of the frame. K is a stop on the face of the wheel H which in
the rotation of that wheel comes in contact with the fixed pointer Land stops further
rotation thereof. M is a worm on the axis C which rotates the wheel H until the stud K
locking against the fixed pointer I stops further rotation when the worm continuing
to be rotated works itself up the teeth of wheel H lifting its axis C and also the
disc D mounted on its head, said rising being controlled by adjustable collars 0, 01,
which come against the upper bearing N' in which and in the lower bearing N the
axis C is supported and slides.
G is a weight hung by a chain G' passed over a pulley G' said chain or it may be
cord or band, being wound around the axis of the throwing off wheel b and having a
constant tendency from the weight G to unwind, rotate the wheel and throw off the
driving gear to stop the machine.
The operation of these devices is as follows:-At the completion of each doffing or
filling of each bobbin by the desired extent of winding the throwing off wheel b
under the influence of the weighted cord G¹ is permitted to rotate until the frame is
stopped by the escapement disc in its rotation on the axis C bringing the opening or
notch D over the arm E and letting that end free so as to disengage the other end F
from the wheel B which then revolves until the frame is stopped. At the same time
this revolution is sympathetically noted on the dial H by the worm M having moved that
wheel to the extent of one peripherical tooth past the pointer L and so on revolution
after revolution as each doffing is completed until the recording wheel H has completed
its entire rotation and the pin K engages the pointer and wheel H becomes a fixture,
upon which the rod or axis C continuing its rotation and the worm M to rotate in engage-
ment with the teeth of wheel H, it mounts thereon lifts the rod C, raises the disc D

page_text: free of engagement with arm E, releases the arm F free of its hold of the wheel b
which wheel at once rotates by the pull of the weight G and the stoppage of the
spinning frame takes place until the overlooker or other person on whom the duty
devolves resets the regulating device and the operation recommences.
Although in the foregoing description of the application of the invention we have
more particularly described it as in connection with a particular form of frame the
improvements are applicable to other varieties of known machines by such slight
modifications according to circumstances of the connections as will be obvious to any
mechanic skilled in the construction of such machinery.
By means of this invention when applied to such spinning machinery the uniformity
of production of "doffings" or quantities of windings of yarns on the bobbins or
spools can be regulated to a great nicety with essential beneficial results in the
subsequent operations of doubling.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
The combination or arrangement and use of parts of means or apparatus for
regulating and indicating the production of yarn or "doffings" in spinning woollen,
worsted, alpaca, mohair and other yarns also the application of the same for regulating
and indicating the like production in doubling yarns substantially as set forth.
