Year: 1871

page_text: LETTERS PATENT to Thomas Abbott, of Blackburn, in the County of
Lancaster, for the Invention of "IMPROVEMENTS IN MACHINERY
EMPLOYED IN SIZING YARN."
Sealed the 22nd December 1871, and dated the 3rd November 1871.
PROVISIONAL SPECIFICATION left by the said Thomas Abbott at the
Office of the Commissioners of Patents, with his Petition, on the
3rd November 1871.
I, THOMAS ABBOTT, of Blackburn, in the County of Lancaster, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY EMPLOYED IN SIZING YARN," to be as follows:-
-
My Invention relates to that part of sizing machines which effects
the marking of the yarns or warps, and consists principally of an
arrangement of mechanism for re-setting the marking apparatus after
the completion and marking of a beam, and before the commencement
of another.

page_text: With the arrangement usually employed for this purpose it is
necessary for the workman to leave the end of the machine where the
beam is, and after going to the side of the machine to make several turns
of a handle to bring the marking bowl back to its original position, and
the object of my Invention is to enable the workman without moving
from his place at the end of the machine to throw out of gear the wheel
which actuates the marking apparatus, and by one turn of a handle
placed within his reach to bring back the marking bowl to its original
position.
I drive the transverse shaft which carries the marking bowl and
tumbler by means of a pair of mitre wheels in the ordinary manner, tho
boss of the mitre wheel upon the end of the longitudinal shaft sliding
on the said shaft on a key or feather and having a neck or groove
embraced by a clip, so that it can be placed in or out of gear with the
mitre wheel on the transverse shaft as desired, by lowering or raising a
lever or rod connected to the said clip -and having a handle within easy
reach of the workman at the end of the machine, or instead of moving
the wheel in or out of gear it may always remain in gear and be placed
loose on the shaft, being coupled and uncoupled as required by means
of an ordinary clutch box actuated in the same manner.
In gear with the opposite side of the mitre wheel on the end of the
transverse shaft is a third mitre wheel fixed on the end of a short
longitudinal shaft, mounted opposite to and in a direct line with the first
named longitudinal shaft, and having at its other end a hand wheel or
crank handle, placed near to the handle previously named, so that the
workman can without moving from his place at the end of the machine,
first throw the driving mitre wheel out of gear by raising the handle of
the rod, and having done so, he then by giving one turn only to the
hand wheel or crank on the end of the short longitudinal shaft he can
bring the marking bowl back to its original position. I would here
observe that fixed on this second longitudinal shaft there is a finger
which, as the said shaft revolves, comes against the rod or lever (or
against a projection thereon and acts as a stop, so as to define the exact
position of the marking bowl. This only acts whenever the rod or lever
is raised, and consequently the driving mitre wheel is out of gear, at
other times when the lever or rod is down the finger does not reach it.
The raising of the rod or lever also raises the finger of the ordinary
indicator (which marks the number of yards on a dial) out of gear with

page_text: its driving mechanism, and a coiled spring then returns the said finger
to the "zero" point on the dial ready to commence measuring a fresh
length.
The second part of my Invention relates to the marking instrument
itself, and consists in dispensing with liquid or semi-fluid ink entirely,
and forming the bowl of a solid piece or block of compressed ink which
will mark the yarn or warp quite as effectually, and will obviate the
inconveniences arising from the use of a wet mark.
It will be obvious that the marker need not in this case be in the
form of a bowl, but may be a bar or block of any other form, and in
some cases instead of mounting it on the transverse shaft by means of a
lever in the ordinary way, I propose to carry it in a vertical slide above
a cam, which is fixed on the said shaft and revolves with it.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Abbott in the Great Seal Patent Office
on the 2nd May 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
ABBOTT, of Blackburn, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Third day of November, in the year
of our Lord One thousand eight hundred and seventy-one, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto I, the said Thomas Abbott, Her special license
that I, the said Thomas Abbott, my executors, administrators, and
assigns, or such others as I, the said Thomas Abbott, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, usc, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
MACHINERY EMPLOYED IN SIZING YARN," upon the condition (amongst others)
that I, the said Thomas Abbott, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands

page_text: DEA
Letters Patent.
NOW KNOW YE, that I, the said Thomas Abbott, do hereby declare
the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement and accompanying Drawings (that is to say) :-
My Invention relates to that part of sizing machines which effects the
marking of the yarns or warps, and consists principally of an arrange-
ment of mechanism for resetting the marking apparatus after the
completion and marking of a beam, and before the commencement
of another.
With the arrangement usually employed for that purpose it is necessary
or the workman to leave the end of the machine (where the beam is),
and after going to the side of the machine to make several turns of a
handle to bring the marking bowl back to its original position, and the
object of my Invention is to enable the workman without moving from
his place at the end of the machine to throw out of gear the wheel
which actuates the marking apparatus, and by one turn of a handle
placed within his reach to bring back the marking bowl and the index
plate to their original positions.
Such being the nature and object of my said Invention for "Improve-
ments in Machinery employed in Sizing Yarn," I will now proceed to a
describe more 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 a Sheet of Drawings
illustrative thereof, and have marked the same with figures and letters
of reference corresponding with those in the following explanation a
thereof.
Fig. 1 is a longitudinal section of so much of the delivering end of a
sizing machine as is necessary to illustrate my improvements, the latter

page_text: Fig. 3 is a section on an enlarged scale of the mechanism of the index
plate.
Fig. 4 is a plan view of an arrangement for dispensing with the long
lever for moving the clutch box; Fig. 5 is a similar view of a modifi-
cation, working with three bevil wheels and dispensing with the clutch
box; and Fig. 6 is a side view of the mechanism for marking the yarn
with solid ink.
In Figs. 1 and 2, a, a, is part of the framework of the machine, b, b,
is the yarn beam, and c, c, the measuring roller; the latter drives the
longitudinal shaft d, d, by spur and worm gearing in the usual manner.
I make the said shaft d, d*, however in two parts coupled together by
the clutch box e, e, on sliding which out of gear by raising the lever
handle ff, the part d can be disconnected from the part d*. The
transverse shaft g, g, which carries the marking bowl h, h, and tumbler
i, i, is driven as usual by a pair of mitre wheels k, k. The marking bowl
runs upon an inking roller 1, 1, which revolves in the ink in the
trough m, m, and thus distributes ink to the marking bowl. Upon the
outer end of the part d* of the longitudinal shaft is keyed a winch
handle n, n, which (as well as the handle of the lever f,f) is within easy
reach of the workman's hand as he stands at the end of the machine, so
that when a beam is finished he can without moving from his place at
the end of the machine first disconnect the part d* of the longitudinal
shaft from the part d by raising the handle of the lever f, and having
done so he then by giving one turn only to the handle n (at the end of
the part d of shaft) can bring the marking bowl back to its original
position. I would here observe that fixed upon the part d* is a finger
o, o, which as the shaft revolves comes against a projection p, p, on the
lever f, which acts as a stop so as to define the exact position of the
marking bowl. This only acts whenever the lever is raised, and con-
sequently the clutch box e, e, is out of gear, at other times when the
lever is down the finger does not reach it. The raising of the lever f
also at the same time throws the index plate or dial (or the finger itself)
out of gear with its driving mechanism, and allows a coiled spring to
return the same to the "zero" point ready to commence measuring a
fresh length.
On referring to Fig. 3, f,f, is part of the lever which is provided with
a pin q, q, working in an inclined slot r, in a short lever 8, attached to a
slide t, t, which (when the lever S., is raised) draws the spur pinion «,

page_text: out of gear with the wheel v, and allows the coiled spring wo to turn the
index plate back to "zero." When the apparatus is thrown into gear
again the revolution of the index plate or dial winds up the spring ready
for fresh action.
It will be evident that in cases where a fixed dial and a revolving
index are used it is the latter that will have to be thrown out of gear and
returned to "zero" in a similar manner.
In the arrangement shown at Fig. 4 the long lever f.f, is dispensed
with. The boss of the mitre wheel & on the part d* of the shaft slides
on a key or feather, and has a neck embraced by a fixed clip which keeps
it always in gear with the mitre wheel on the transverse shaft g. The
part d* of the shaft is made to slide longitudinally so as to throw the
clutch box e, e, into or out of gear, and when in gear is held in position
by means of a clip q (see detached view Fig. 4*). When this clip q is
raised the workman can draw the shaft d* in the direction of the arrow 1
so as to bring the clutch box out of gear, and then turn the handle 12
back as before described. The disc p draws back the slide t, t, and a
tooth o on the disc acts against a fixed stop r, to define the position of
the marking bowl on starting a fresh beam as before.
In the arrangement shown at Fig. 5, the clutch box is dispensed with a
and three mitre wheels are employed. The wheel * on the part d* of
the longitudinal shaft is always in gear with the mitre wheel on the end
of the transverse shaft g, but the boss of the wheel on the part d of the
shaft slides on a key or feather, and has a neck or groove embraced by a
clip or fork on the end of the lever ff, so that when the beam is finished 2
wheel can be thrown out of gear whilst the marking bowl is turned
back by the handle nas in the previously described arrangements.
The second part of my Invention, which relates to the marking
instrument itself, is illustrated by Fig. 6, and consists in dispensing with
liquid or semi-fluid ink entirely, and forming the bowl of a solid piece or 3
block a, a, of compressed ink, which will mark the yarn or warp quite as
effectually, and will obviate the inconveniences arising from the use of a
wet mark.
It will be obvious that the marker need not in this case be in the form
of a bowl, but may be a bar or block of any other form. I prefer to 3
mount and drive it as shown by fixing on the transverse shaft g a cam
or wiper h, which acts against a bowl i, attached to the slide, which.

page_text: carries the marker a, or the marker may be carried by a lever as shown
at Fig. 1.
Ilaving 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 wish it to be understood that
I claim as my Invention principally making the longitudinal shaft d, d*,
in two parts and connecting them together by a sliding clutch box e, e,
substantially as shown at Figs. 1 and 2, or by a sliding mitre wheel,
subtantially as shown at Fig. 5, or by sliding one part of the longitudinal
shaft, substantially as shown at Fig. 4. In order to allow the workman
to restore the marking apparatus to its original position by one turn
only of the handle n (or a hand wheel or lever) fixed at the end of the
part d of the shaft within easy reach of his hand.
Secondly. I claim the combination with the lever f, f, of the pin q,
slot r, lever 8, and slide (Fig. 3) or other equivalent device for
returning the dial plate or index finger to the " zero point.
"
Thirdly. I claim the combination with the shaft d* and lever fof the
finger o, and stop p, or other equivalent device for defining the position.
of the marking bowl or instrument at the commencement of a fresh
beam.
And, fourthly. I claim the use in such machines of a solid bowl,
block, or bar, of dry (on nearly dry) compressed ink to form the marking
instrument, whether carried and operated as shown at Fig. 6, or in any
suitable manner, instead of using fluid or semi-fluid ink as hitherto other
practised.
In witness whereof, I, the said Thomas Abbott, have hereunto set
my hand and seal, this Thirtieth day of April, in the year of our
Land One thousand night hundred and savanty-two
