My improvements relate to mechanism used in doffing the bobbins from the
machine known as the "ring and traveller" spinning throstle, and the ring doubling
frame commonly called the "ring frame."
The improvements consist, firstly, in putting a rail or bar between the ring rail
and the bolster rail, and so arranged that when the ring rail is lowered to a certain
position, it takes hold of the intermediate rail or bar by means of levers attached to
the same, and when the ring rail is lifted up again, the intermediate rail gets hold
underneath of the full bobbin, and loosens the bobbin which at that time is fast on
the spindle.
If it be required to throw the bobbin off the spindle entirely, the ring rail is
lifted up to the top of the spindle, and the intermediate rail being attached thereto
and still underneath the bobbin, it will lift the bobbin off.

throwing it off the spindle) at that moment the levers are detached from the ring.

. My improvements relate to mechanism used in doffing the bobbins from the
machine, known as the "ring and traveller" spinning throstle, and the ring doubling
frame commonly called the "ring frame."
The improvements consist, firstly, in putting a rail or bar between the ring rail
and the bolster rail, and so arranged that when the ring rail is lowered to a certain
position, it takes hold of the intermediate rail or bar by means of levers attached
to the same.
And when the ring rail is lifted up again, the intermediate rail gets
hold underneath of the full bobbin, and loosens the bobbin which at that time is
fast on the spindle.
If it be required to throw the bobbin off the spindle entirely, the ring rail is
lifted up to the top of the spindle, and the intermediate rail being attached thereto.
and still underneath the bobbin, it will lift the bobbin off.
When the proper height is reached (for loosening the bobbin on the spindle, or
throwing it off the spindle) at that moment the levers are detached from the ring
rail, and the intermediate rail drops down to its former position; and stops there
until it is wanted for doffing again.
My second improvement is designed to give the bobbin a rotary motion just at
the time that the bobbin is loosened on the spindle. When the bobbin is loosened
on the spindle as described above, I attach a bar or rod, one end to a lever, and the
other end to the intermediate rail or bar, and at the time the lever is pushed
forward, it slides the intermediate bar or rail, which being at that time underneath
the bobbin, it turns the bobbin round. and breaks the thread which is attached.

and roller.
Thirdly. My improvements consist in attaching springs to the intermediate rail
or bar. To these springs I connect a wire or rod which reaches right across the
frame;
it will be seen that when the intermediate rail or bar is lifted, it lifts also all
the guide wires which are hinged to the frame side.
When the frame is ready to start spinning again, and the intermediate rail or
bar comes to its former position, it brings all the guide wires down with it at the
same time.
Such being the nature and object of my said Invention, I will now proceed to
describe in detail the manner in which the same is to be or may be performed or
carried into practical effect, and in order that the same may be clearly understood,
I have annexed hereunto four Sheets of Drawings illustrative thereof, and have
marked the same with figures and letters of reference corresponding with those in
the following explanation thereof.
Sheet 1 of the annexed Drawings illustrates the application of my Invention to a
"ring throstle" made according to the Specification of Letters Patent granted to me,
and dated March 11th, 1878, No. 972; Fig. 1 being a front elevation; Fig. 2, a
transverse section; and Fig. 3, a plan view of so much of the throstle as is necessary
to illustrate my Invention.
A¹ is the bolster rail, B the spindles, and C.the bobbins; on the bolster rail there
is a cover or plate J, and on this plate there is a rail or bar K which rests in such a
manner that it can be sliden horizontally along the covering plate J. This latter is
provided with some studs n², to which there are attached the levers M, the same
swinging loose on the studs n².
The ring plate D has some brackets m¹ attached, in these brackets are fixed studs
n' fastened in such a position, that when the ring rail is lowered (that is to say,
when the bobbin is full) the ring rail D. is lowered below the bobbin C until it
reaches the cup b, which is fastened to the spindle. It will here be seen that in
doing so the yarn is running on the cup b, and at the same time the stud n' pushes
back the lever M and gets underneath of the nose or catch at the upper end of the
lever M, until it has got a firm hold of it. After the ring plate D is lifted up again
to the height of the bobbin in a position for starting again, as seen at the left-hand
of Fig. 1. To the lever M there is attached a balancing weight L, this weight L is
so adjusted, that when the lever M swings loose on the stud n², it always pushes
against the stud n³ which is fastened to the bottom rail A² by the bracket m³. The
balance weight L has an incline on one side, the ring rail D being lifted up to
such a height that the loose rail or bar K passes the cup b and touches the bobbins
C underneath, and by this means loosens them off the spindles. The rail or bar K
has a stud n fastened to the same running in a slot in the lever p¹, again on the
other end p¹ is attached by a link p² to another lever P, the other end of which is
fastened to the lever M at gt by a link p. The lever P swings on a stud which is
fastened in the rail A2. When the stud n³ is at the bottom of the incline of the
weight L, the nose of the lever M. releases itself, but before entirely disengaging
itself from the stud n', it pushes the lever p² on one side, which again moves the
rail K. The rail K at the time being underneath the bobbin C, and the bobbin
being already a little loosened from the spindle, the bobbin receives through the
rail Ka rotary motion, and breaks the end of the yarn which is attached to the
cup b. This being done, and the stud n³ having reached the lowest point of the.
incline of the weight L, the lever M disengages itself from the stud n³, the covering
rail J falls into its former position, and carries the loose rail K with it. The levers
M are put alternately on the front and back of the rail. The spring R which is
fastened to the lever P at one end, and at the other end to the rail A2, lifts the rail.
K back into its proper position. The springs Q placed in the hollow bolster rail A¹
act as buffers. The full bobbin now being taken off the spindle, and empty ones
put on instead, the ring throstle is set on again and ready.

page_text: Sheet 2 shows an application of the same doffing arrangement adapted to the so-
called "Booth sawyer" spindle, the only difference being, as there is no covering
plate to the bolster rail, the bolster which carries the spindle commonly being
fastened to an ordinary rail A¹, that instead of lifting the covering plate as described
with reference to Sheet 1, the rail K which carries the stud n² is itself lifted. The
rail K when in its normal position, lays on the bolster rail A¹. The loose rail or
plate K instead of being single (as shown in the Drawing) is made double, and
connected in such a manner as to lift and turn the bobbin on both sides. Under-
neath the rail J the two plates K. are connected together by horizontal levers t¹ (see
plan Fig. 3 and section Figure 4), the same swinging in their own centres, and
having slots on each side for the studs s' fastened on the said plates, and receive by
these means a parallel motion, the lever p' moving one of the plates K as béfore
described. The rest of the working of the apparatus is the same as in Sheet 1.
Sheet 3 illustrates the application of my doffing motion to the so-called "Rabeth
spindle," an American Invention. The doffing plate K slides horizontally in the
brackets J, the brackets J slide vertically in the guides J', which are fastened to the
rail A. The studs n² are fastened to J, and the stud n³ which works the lever M
at the incline of the weight L is attached to a bracket m³, the same being bolted to
the rail A.
The lifting motion is the same as in the foregoing Drawing, viz., the ring plate D
with the stud n¹ lifting the bracket J, the said bracket being guided by the spindle
bolster B. The rotary motion to the bobbin is given in the same manner as
described in Sheet 1. With this doffing motion there is also connected a motion to
turn up the guide wires at the same time; the working of the apparatus is the
following:-
The bracket J carries on its back end a rod N. On the roller plate P of the
frame there are bolted the two brackets u and v. A pin on the bracket u carries
the two levers u¹ and u³, the bottom end of u¹ is formed so as to push against the
end of the rod N, the other end has the pin w fastened to it. One side of the lever
u2 carries the grooved pulley us, and ends in a spring hook, the other end is a
balancing weight. The bracket u carries on the top the loose guide pulley w³. The
bracket carries the catch wheel v², to which is fastened the pulley v³, and an
endless cord or wire passes from the pulley round the roller P2 (see Fig. 2).
Each guide wire is supplied with a hook w¹ at its centre on the top side, these
hooks are connected by a wire, the latter being attached by a cord w² to the pin w
on the lever u. When the frame is working, all the levers are out of work, as well
as the catch wheel v2, because the cord is slack on the pulley v¹. The working of
the apparatus begins as soon as the lever M is caught by the stud n¹ with the
lifting of the rail K and the bracket J, the rod N moves upwards, touches the end
of the lever u¹, and turns the two levers u¹ and u², the pin w turns the guide wires
up by means of the cord w² running over the guide pulley w³. At the same time
the lever u catches with the hook on its end the catch wheel 2, the pulley u³
tightens the cord ³, and acts as a brake on the catch wheel. The roller P² is
stopped before this position of the levers. When the empty bobbins are put on
and the frame set in motion, the cord K³ turns the catch wheel v2 back, loosens the
hook on u², and the balancing weight puts the guide wires back into their normal
position. The wire and hooks can also be put on the bottom of the guide wires
instead of being on the top side, if it is found more convenient.
M.
Sheet 4 shows the adaptation of my improved doffing motion without the levers
The doffing plate K is lifted by rakes Y and wheels Z, which are fastened to
a shaft X, the same running the length of the frame. This shaft X carries a second
wheel Z2 keyed on, in which a worm is working. The rail A has a double bracket
Y2 bolted to it, in which the shaft with the worm keyed in on one side, and a
handle Y on the other, revolves. By turning the handle Y' motion is given to the
shaft in the bracket, the worm turns the shaft X which runs along the frame, and
the wheel Z4 gearing into the rack Y₁, lift the doffing rail K underneath the
bobbin.

page_text: The rotary motion to the bobbins is given in the following manner:-The doffing
plate K is guided by a stud K' fastened to the lifting rack Y, and which works in
a slot, this slot in the plate K having such a form (see Fig. 3) that when the said
plate is pushed forward by the lever p, the plate is moved inwards towards the
bobbins B. A rib cast on or fastened to the plate, presses the side firmly against
the bobbin B, the bobbin being already a little loosened off the cup b is turned, and
the ends broken with greater certainty. The lever p receives its motion by a small
pair of bevil wheels Z3, one of them being keyed on the shaft X which runs along
the frame, the other carried in a bracket bolted to the rail A². On the same shaft
which works in the brackets and carries the wheels, there is on the outside a crank
n³ fastened on; the crank pin working in a slot of the lever p which gives the
horizontal motion to the doffing plate K.
It must be here clearly understood that my improved doffing motion can be
adapted to any class of ring spinning frame, and to different sorts of ring spindles,
as I have shown in four different ways; the arrangement on one might be taken to
another, and vice versa.
Having now described the nature and object of my said Invention, together with
the manner in which the same is to be or may be performed or carried into practical
effect, I would remark in conclusion that I do not bind myself to the exact form of
levers or plates as shown in the annexed Drawings, but I distinctly claim, -
First. Giving a rotary motion to the bobbins for the purpose of breaking the
ends of the yarn which are attached to a spindle or cup.
Secondly. The employment of a plate which runs along the frame and lifts the
bobbins off with self-adjusting levers.
Thirdly. Lifting the guide wires by means of the rollers and doffing plate, all
substantially as herein-before described and illustrated by the Drawings annexed.
In witness whereof, I, the said Ferdinand Henry Ziffer, have hereunto set
my hand and seal, this Fifteenth day of October, in the year of our Lord
One thousand eight hundred and seventy-eight.
