PROVISIONAL SPECIFICATION left by the said Ferdinand Henry
Ziffer at the Office of the Commissioners of Patents, with his
Petition, on the 9th October 1874.
I, FERDINAND HENRY ZIFFER, of the Firm of Ziffer and Walker, of
Manchester, in the County of Lancaster, Engineer, do hereby declarc
the nature of the said Invention for "AN IMPROVED TAKING-up and LETTING-
OFF MOTION APPLICABLE TO LOOMS FOR WEAVING, PART OF THE INVENTION BEING
ALSO APPLICABLE TO SIZEING AND OTHER MACHINES FOR PREPARING WARPS," to be
as follows:

page_text: other machines (requiring such devices) positive taking-up and letting-
off motions, so that the yarn or warp beams and the cloth or work
beams may have imparted to them a positive motion of an extent
depending upon the decreasing or increasing diameter of the beams to
which the gearing suitable to produce such motion is applied.
In carrying out my Invention and adapting it to a loom for weaving
I mount on brackets connected with the shaft or axle of the warp and
cloth beams of the loom or on the shaft of an intermediate roller a
toothed wheel, which is driven by differential gearing in combination
with a sun-and-planet motion, so that as the warp or yarn beam
decreases in diameter as the weaving proceeds the speed of such beam
will increase, and as the diameter of the cloth or work beam increases
the speed of its rotation shall decrease, so that in both cases the surface
speeds of the beams shall always remain the same whatever may be the
diameter of such beams.
In some cases the differential motion may be used without the sun-
and-planet motion.
The positive taking-up motion above described as applied or adapted
to looms for weaving may also with advantage be adapted to machines
for sizeing or preparing warps, and to other machines in which a positive
taking-up differential motion is required.

APPLICABLE TO LOOMS FOR WEAVING, PART OF THE INVENTION BEING ALSO APPLI-
CABLE TO SIZEING AND OTHER MACHINES FOR PREPARING WARPS," upon the
O condition (amongst others) that I, the said Ferdinand Henry Ziffer,
my executors or administrators, by an instrument in writing under my,
or their, or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the
5 Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Ferdinand Henry Ziffer, do hereby
declare the nature of my said Invention, and in what manner tho.
same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the Drawing
hereunto annexed, and to the letters and figures marked thereon (that is
to say):-
My Invention consists in adapting to looms, sizeing machines, and
other machines for preparing warps certain novel arrangements of
positive taking-up and letting-off motions, so that the yarn or warp
beams and the cloth or work beams may have imparted to them a
positive motion of an extent depending upon the decreasing or increasing
diameter of such beams as the action of the loom or the sizeing or other
machine proceeds.
In Sheet I. of the accompanying Drawings Figures 1 and 2 shew my
improved positive differential taking-up motion as applied to a loom,
Fig. 1 being an end view of so much of the loom as will serve to explain
the application of the motion thereto, and Fig. 2, a front elevation of the
same with the differential motion in partial section; Figures 3, 4, and 5
shew the differential motion detached from the loom.
In Fig. 2 A is a bracket bolted to the loom side for carrying the
taking-up motion; B is a shaft mounted in the bracket A, and carrying

page_text: at its outer end an ordinary change pinion C; D, Fig. 1, is a stud wheel
mounted on a pin e' carried by a wheel plate e² from the framing and
gearing into the pinion C; E is a pinion cast on the stud wheel D and
gearing into a wheel F on the end of the cloth beam; G is a ratchet
wheel actuated by the means at present used in the ordinary positive
taking-up motion, and upon its boss is cast a mitre wheel Y. In gear
with this wheel is a pair of mitre wheels H, H, which are intended to
give motion to the shaft B through a mitre wheel X, which is fastened
on that shaft with set screw. These mitre wheels H, H, turn freely on
stud axles c', c', projecting inwards from the periphery of a cylindrical
casing a¹, which surrounds and is concentric with the shaft B. I is a
compensating ratchet wheel for working differential motion keyed on a
tubular extension of excentric bush J and concentric with the shaft B.
This excentric bush works loosely on the shaft B and is intended to
carry a pinion K. fitting loosely and gearing into the rings of teeth or
internal wheels L, M, of unequal pitch constituting my differential
gearing. The internal wheel L has one or more cogs less than the
wheel M, and it is cast or fastened to the bracket A. The internal
wheel M is cast with or fastened to the cylindrical casing H'. These
wheels are shewn detached and on an enlarged scale at Figures 6 and 7.
N is a swinging arm mounted on a trunnion of the bracket A. and
forming with a pawle N', which it carries, a setting-up motion. This
pawle drives the compensating ratchet wheel I, and thereby modifies the
intermittent axial motion imparted through the mitre wheels above
described to the shaft B. O is a link attached by a pin d' at one end to
the swinging arm N of the setting-up motion, and at the other to a stud
pin / carried by a slide moving in a vertical slot in the oscillating slide
plate P pendent from and working on a stud ¹ attached to the loom
side. Qis a forked link attached to a stud Q', which slides in a slot W
in the oscillating slide plate. This forked link Q is jointed to an arm R
fastened to a rock shaft S, which shaft extends across the loom and
carries also an arm T that bears upon the cloth roller, and is raised as
the cloth accumulates upon and increases the diameter of that roller.
L' is a link fitted to a stud P³ on the slay sword U and connected at its
opposite end to the oscillating plate P by the stud P¹ for the purpose of
transmitting motion from the slay sword to the plate P.

page_text: lever I carrying a pawle LP. This pawle I takes into and drives the
ratchet wheel G. In the lower part of the oscillating lever L³ a slot L^ is
formed to receive a light rod L' projecting from the slay sword. This
said slay sword U receives motion from crank shaft L through crank
arm I, motion being given to crank L' through driving pulley I", as
usual. L' is a pawle which takes into the ratchet wheel G to prevent
that wheel G from slipping. This pawle is carried by a light shaft L",
extending across the loom.
When the loom is set in action a reciprocating motion is imparted to
the slay sword U, which through the rod IP oscillates the lever L³ and
causes the pawle L³ which it carries to drive the ratchet wheel G. The
wheel G is thus caused to move a tooth for each beat up of the slay
sword. Thus for each pick or beat up the mitre wheel Y on the inside
of the ratchet wheel G gives motion through the mitre wheels H, H,
and X to the shaft B on end of pinion carrying the change pinion O
forming part of the train which drives the cloth roller or beam.
As the cloth being wound on the beam increases in diameter a corre-
sponding decreasing of speed is given to the cloth roller V by the
positive differential motion afore-named, and conveyed to the said yarn
beam V through the sun-and-planet motion afore-named in the following
manner-The slay sword U gives motion by the link O to the oscillating
slot plate P, the said plate P giving motion to the pin ³, which fits
into its slot W and is connected to the arm N of the setting-up motion.
The pawle N' of this arm drives the ratchet wheel I, which gives motion
through the sleeve or bush J to a pinion K, and this pinion by working
round the inside of fixed and free internal wheels L, M, will at each
revolution of the sleeve J cause the caso a¹ to turn on its axis and carry
with it the mitre wheels H, H, which will thus fail to impart the full
speed of the mitre wheel Y to the mitro wheel X on the shaft B and to
the cloth beam.
At the commencement of weaving the stud h¹ in the oscillating
plate P is set at the top of the slot W at a point opposite the working
journal of the plate P. As the cloth beam fills, its increasing diameter
elevates the arm T resting on the cloth roller V and through the shaft S
extending across the loom, depresses the arm R connected by the link Q
with the stud h¹ in the slot of the oscillating plate P and lowers the
position of the stud, forcing it away from the centre of motion of the

page_text: plate. By this means the motion of the arm N obtained from the
oscillation of the plate P will be increased, and the said arm N will be
caused to pass through a greater arc of a circle and make its pawle N¹
take more teeth of the ratchet wheel I at each motion of the slay
sword U. Thus the increasing axial motion of the ratchet acting
through the sun-and-planet motion will retard the motion of cloth beam
in proportion as the cloth beam fills.
In Sheet II. of the Drawings I have shewn my improved positive
differential letting-off motion as applied to a loom. Fig. 1 is a sido
elevation of so much of a loom as will serve to explain the action of the 1
improved mechanism; Fig. 2 is a back sectional elevation; Fig. 3 is an
elevation of an internal wheel; and Fig. 4 is an elevation of an internal
wheel having a tooth more or less than Fig. 3. The taking up and
letting off are purposely not shewn on the same loom, although they
will and may work conjointly on the same loom.
1
Keyed to the end of yarn beam Y which rests in bracket W bolted to
loom side is a spur wheel S. Into this spur wheel S gears a pinion R
fastened on a shaft Q. The said shaft Q works in a sleevo bracket X
extending from inside to outside of framing. On the inside of said
sleeve bracket X I cast an internal wheel O, the said wheel O being fixed 2
and not capable of revolving on its centre. On the said shaft Q I fit a
similar internal wheel P having a tooth more or less than the one fixed
on bracket X, and fastened by a set screw Y or other suitable means to
the said shaft Q. On said shaft Q I fit a loose excentric sleeve or
bush M, which extends through the sleeve bracket X, and on the end of 2
this bush I key a ratchet wheel L.
The excentric portion of the bush carries a spur pinion N, which
gears into the internal wheels O, P, and is of a diameter equal to about
three-fourths of that of the internal wheels O, P, and of a breadth
equal to their combined width. On the outside of the sleeve bracket X 3
I fit loosely an arm J which carries at its upper part a pawle K gearing
into and actuating the ratchet wheel L. On the same arm J and at a
point somewhat below that of the position of pawle K I attach a stud U,
and fit on to said stud U a link I, the opposite end of link I being
connected to a stud a¹ in an oscillating side plate C, said oscillating side 3
plate C having a boss cast on its upper part, which I bore and form into
a journal, into which I fit a stud 6, and bolt the same to framing of

page_text: loom side. The said plate c is made to work loosely and oscillate on its
attaching stud b'.
By means of the slot = I connect a second link D to the oscillating
plate, and the opposite end of this link I connect by a stud e¹ to an
5 arm E attached to a shaft F extending across the loom, the arm E being
fastened by a set screw or otherwise. On the same shaft F the
arms G, G, support a roller H, the said roller H resting against the yarn
beam Y, motion being imparted to the loom through the driving
pulleys and crank shafts to slay sword A through crank arm s³, a
O reciprocating motion is given to slay sword A, which is conveyed to
oscillating plate c by a link B connected by stud ci with oscillating plate
and with slay sword A. by means of the stud ď³. When the beam Y is
full or charged with yarn the link stud a' in the slot of the oscillating
plate O is set to give only one tooth at each beat of the slay sword A.
On the yarn beam Y diminishing in diameter the roller H and arms G, G,
will follow the diminishing diameter of the beam Y and adjust the
stud a¹ in the slotted plate C, so as to increase the speed of the ratchet
wheel L, which through the spur gearing will accelerate the letting off
of the yarn from the beam Y.
In Sheet III. of the Drawings I have shown my improved positive
differential winding-on motion as applied to a sizeing machine. Fig. 1 is
a partial side elevation of the machine, and Fig. 2 is a plan view of the
same.
"
Instead of employing the present double cones or similar gear for
driving the yarn beam in frames of this class I use the positive differ-
ential motion above described, applying it in the following manner :—
From the main driving shaft motion is conveyed to the pulley Z on the
shaft A, which carries a pulley W. On a shaft R running parallel with
shaft ▲ I fit a second pulley W¼, and convey motion from first to second
motion shaft by belt W' or gearing. On the shaft R I fix a mitre
wheel Q which gears through a pair of mitre wheels s², s², with a mitre
wheel & cast on the end of a sleeve shaft which fits on the shaft R.
This sleeve shaft carries at its opposite end a spur pinion. P¹ gearing
into carrier wheel P' and through said carrier P² to beam wheel P³
driving yarn beam X. Surrounding the shaft RI fit a cylindrical
casing V which carries the pair of mitre wheels 8³, 8³, as in the first
escribed arrangement of sun-and-planet motion,
8

page_text: On the outside of the casing V I cast a ring of spur teeth P which
gear with a spur wheel O mounted on a shaft L extending across the
frame and carried in suitable bearings on the framing. To each end of
this shaft L I key a ratchet wheel M, M; and adjacent thereto I mount
These arms
on the same shaft arms K, K, which work loosely thereon.
carry pawles N, N, which take into the teeth of the ratchet wheels M, M.
At a point somewhat below the pawles N, N, in the arms K I fit a
stud a¹ to receive severally a link J which is connected at its opposite
end to a stud 6' in the oscillating plates D, D. These plates are con-
nected to the frame by stud d'. On the same stud 6' I connect a second:
link E and connect the opposite end by means of the stud e¹ to an arm
or arms F, F, fastened on a shaft G by set screw or otherwise. On the
same shaft G I fit arms H, H, carrying a roller I which rests against
yarn beam X. To the aforesaid oscillating plates D, D, I fit links O, C,
which have on their opposite ends excentric straps that embrace
excentrics B, B, on the shaft A. Through these links C, C, motion is
given by the shaft to the oscillating plate D, D; and these plates D, D,
give motion to the ratchet wheels M, M, which through the pinion O
on the shaft L and wheel P drive the cylindrical casing V.
On motion being conveyed from the shaft A through the pulley W, W',
to the shaft R the mitres s³, 83, will be caused to drive the wheels on the
sleeve shaft, and this shaft will in turn give motion through the carrier
wheels P³, P³, P³, to the yarn beam X.
The differential motion it will be seen is obtained by the excentrics B, B,
on the shaft A. giving motion through the link arms O, C, to the
oscillating plates D, D, which through their connection with the arms K
carrying the pawles N, N, will give motion to the ratchet wheels M, M,
and shaft L and the wheel O on said shaft L gearing into the ring of
teeth on the cylindrical casing V on second shaft R and, constituting
with its internal gearing the sun-and-planet motion, will set the same in
action. As the roller I resting against the yarn beam X is depressed,
as the yarn beam X fills it will, acting through the connecting
links H, F, E, raise the stud 6¹ on the oscillating plates D, D, and
thereby decrease the speed of the yarn beam X through the action of
the sun-and-planet motion.
Having now set forth the nature of my Invention of "An Improved
Taking un ond Letting off Motion Applicable to Looms for Weaving.

page_text: Part of the Invention being also Applicable to Sizeing and other
Machines for Preparing Warps," and explained the manner of carrying
the same into effect, I wish it to be understood that under the above in
part recited Letters Patent I claim,―
First. The application to looms of the differential taking-up and
letting-off motions, arranged and actuated as described with reference to
the Drawings, and that whether the differential gearing and sun-and-
planet motion be used in combination or independently of one another.
Second. The application to sizeing and analogous machines used in
preparing warps of the arrangements of differential taking-up or winding-
on motions above described, such motions being applied as explained
with reference to Sheet III. of the Drawings.
In witness whereof, I, the said Ferdinand Honry Ziffer, have
hereunto set my hand and seal, the Twenty-fourth day of
December, in the year of our Lord One thousand eight hundred
and seventy-four.
