PROVISIONAL SPECIFICATION left by the said Ira Dimock at the Office
of the Commissioners of Patents with his Petition on the 28th Decem-
ber 1860.
I, IRA DIMOCK, Machinist, of Florence, Hampshire County, State of
Massachusetts, United States of North America, temporarily residing at the
City of Manchester, in the County of Lancaster, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR CLEANING.
SORTING, ACCORDING TO SIZE, AND DOUBLING SILK AND OTHER THREADS," to be
as follows:-
My Invention relates, firstly, to mechanism for cleaning silk, and consists
in mounting one jaw of a cleaner on an axis parallel to the space to be formed
between the jaws, and in causing the said jaw to be kept in its place when
operating upon the thread by a spring; by this means the space between the
jaws for the thread to pass through will be maintained parallel under every
variation of adjustment, and the moveable jaw may be readily withdrawn from
[Price 8d.1

page_text: the fixed jaw to remove dirt, the spring bringing the moveable jaw back to
its correct position when permitted.
My Invention relates, secondly, to machinery for sorting silk according to
size, and refers to such machinery as operates in a manner similar to that
described in the Specification of the Patent granted to Alfred Vincent Newton,
No. 1945, and dated the twenty-seventh day of August, in the year of our
Lord One thousand eight hundred and fifty-eight, in which Specification the
thread guide for distributing the thread upon the bobbin is caused to be
slided upon the traverse bar when a change in the thickness of the thread
occurs by two levers; and this part of my Invention consists in employing
only one lever in place of the two in combination with suitably shaped slots
or grooves formed in or attached to the slide of the thread guide.
My Invention relates, thirdly, also to mechanism similar to that described in
the aforesaid Specification of Alfred Vincent Newton, when the thread in
place of being wound upon one long bobbin as described in the aforesaid
Specification is distributed upon separate bobbins (placed on the same axis or
spindle) having thin heads, the thread passing over these thin heads in
changing from one bobbin to another, the cbject of this part of my Invention
being to diminish the accumulation of the thread near the heads of the bobbins
when the thread guide is stationary during the time the change is being made
in its position on the traverse bar, which accumulation of the thread renders
more difficult the finding of the ends of the thread when the thread from the
bobbins after being separated has to be unwound from them. And this part of
my Invention consists in mounting the thread guide, or an additional thread
guide upon the thread guide slide so that the thread guide can be moved side-
ways, and in arranging it so that when the thread guide slide is prevented from
moving with the traverse bar, a notch, projection, or other suitable arrange-
ment on or in the traverse bar will become conuected with and give motion to
the thread guide so as to move it (carrying the thread with it) in an opposite
direction to that in which the traverse bar is moving at the time the change
is taking place, the connection between the traverse bar and the thread guide
ceasing at the time or before the change in the position of the thread guide
slide is fully effected, so that time is given for a spring attached to the move-
able thread guide to bring it back to the central or normal position.
My Invention relates, fourthly,also to mechanism similar to that described in
the aforesaidSpecification of Alfred Vincent Newton, and its object is to prevent,
as far as possible, a thread, after a change in thickness has taken place, from
continuing to be wound on the same bobbin as that for the size previously
indicated during the short space of time occupied in effecting the change in the

page_text: position of the thread guide, and this part of my Invention consists in arranging
so that the length of thread between the guaging mechanism and the bobbin
on which the thread is wound will be equal or nearly so to the length which
will be wound in the time occupied between the moment a change is indicated
and that moment when the thread passes over the heads of the bobbins,
taking an average of the time of effecting the change and length of the thread
wound in that time. The required length of thread may be obtained by causing
the thread to descend from the guaging apparatus and then pass under a
pulley, and then ascend to the bobbin upon which it has to be wound.
My Invention relates, fifthly, also to mechanism similar to that described
in the aforesaid Specification of Alfred Vincent Newton, and applies more
particularly when sizing fine threads, the object of this part of my Invention
being to reduce or remove the strain upon the thread caused by the friction
or drag of the guaging roller or rollers and pulley, and by the same means
obviate the necessity for a delicate adjustment of the weighted pulley, thus
obtaining a quick action in the guaging mechanism when a change of
thickness in the thread takes place; and this part of my Invention consists
in giving a positive rotating motion to the roller or rollers, which have
hitherto been driven by the friction of the passing thread in the same direction
but a little faster than the said roller or rollers would be driven by the
passing thread alone. This part of my Invention further consists in applying
arrangements which will retard the speed of the said driven guaging roller or
rollers when the thread becomes slack and stop the roller or rollers when
the thread happens to break. This may be accomplished by a lever which
carries a "brake" surface near its fulcrum, which will act to retard or stop
the driven roller when the lever falls in one position, but will allow the
roller to rotate without obstruction so long as the lever is held in another
position. The positions of this lever are governed by the thread, the end
of the lever being sustained by the thread, and if the thread becomes
slack or broken the lever will be allowed to fall and act as above described.
My Invention relates, sixthly, to a novel system of sizing or indicating the
changes in the thickness of threads, and consists in passing the threads to be
sized between surfaces which always remain at the same distance apart, the
space between them being sufficient to allow the thickest portions of the thread
to pass while the thinner portions will pass more freely, the friction of the
passing thread upon the surfaces being in proportion to its thickness, and in
arranging these surfaces so that one or both of them will be carried forward
by the drag or friction of the thread when the friction increases, and brought
back by a weight or spring when the friction decreases, so that one or both

page_text: surfaces will move forward or backward according to the amount of friction
with which the passing thread acts upon the surfaces, and thus indicate the
thickness and the changes in the thickness of the thread, the movement pro-
duced by these changes being made to bring into operation arrangements for
stopping the winding of the thread or for changing the distribution of the
thread according to its thickness. In carrying this part of my
Invention into
effect a roller and pulley similarly arranged to those described in the aforesaid
Specification of Alfred Vincent Newton may be employed, except that the
pulley need not be excentric, the space between it and the roller being the
same in every position of the pulley. The roller in this arrangement may be
positively driven as described under the fifth head of this Provisional Specifi
cation, otherwise a pair of rollers may be placed in a frame or carried by a
lever and balanced, and one of the rollers may be positively driven to take
the strain off the thread passing between the rollers. The roller which is not
driven may have a small toothed pinion on its axis gearing with a fixed toothed
rack, and thus the latter roller will remain stationary till an increased
thickness of the thread gives friction sufficient to cause it to rotate, and thus
change the position of the frame carrying the rollers, which frame is weighted
so as to be brought back when the friction of the passing thread diminishes.
Otherwise two surfaces may be arranged so as to come within a fixed distance
of each other, being kept in that position by a spring which will allow the
surfaces to recede from each other when a knot has to be passed, but will
be practically rigid to the even portions of the thread, these surfaces being
carried on the end of a balanced lever weighted to change in position according
to the amount of friction put upon the surfaces by the passing thread.
It may be explained that it is not necessary in every case that the surface
which is carried forward when the friction increases by reason of the
increased thickness of the thread shall go backward when the friction
diminishes by reason of the diminished thickness of the thread, as the
surfaces employed may be a pair of rollers, one of them being so arranged as
only to revolve when the thread is thick, ceasing to revolve when the thread
becomesthin;arrangementsbeing applied which will be acted upon by the roller
when it begins and when it ceases to revolve, and thus indicate the changes in
the thickness of the thread and communicate the required movements to the
mechanism which stops the bobbin on which the thread is being wound, or
adjusts the thread guide so as to wind the thread on the proper bobbin.
My Invention consists, seventhly, in a system and arrangements for sizing
and at the same time doubling threads so as to produce doubled or compound
thread of uniform thickness, or so as to sort compound threads according to

page_text: thickness, which will be produced with fewer piecings of the thread than
when the threads are first sized, and then doubled by the ordinary process as
the deficiency of thickness of one of the threads will frequently be compen-
sated by the excess of thickness of the other threads forming the doubled or
compound thread. If I wish to produce a continuous compound thread of
uniform thickness I cause the mechanism to stop the winding every time there
is a change in the thickness of the compound thread and substitute for
one or more of the single threads other threads of suitable thickness
according as it may be an excess or deficiency in the compound thread, or
I wind the compound thread on to bobbins according to thickness. I guage
or size each single thread forming the compound thread between separate
rollers or surfaces but arranged so that an increase or decrease in the sum
of the thicknesses of the thread only will be indicated. This part of my
Invention may be carried into effect by similar mechanism to that described
in the aforesaid Specification of Alfred Vincent Newton, except that for every
single thread in the compound thread a separate roller or pair of rollers will
have to be added, arranged so that the rollers will act upon each other
directly or by means of connections between their pivots and the roller nearest
the oscillating pulley, which will thus be affected by any increase or decrease
in the sum of the thicknesses of the threads passing between the rollers.
Otherwise this part of my Invention may be carried into effect by arrange-
ments similar to those described under the sixth head of my present Invention
by adding as many surfaces or rollers or pairs of rollers as there are threads
in the compounded thread.
I also combine with my improvements in sizing and doubling the commou
mechanism for detecting the absence of any of the single threads forming
the compound thread and stopping the winding when this occurs.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Ira Dimock in the Great Seal Patent Office on the 9th
May 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, IRA DIMOCK,
Machinist, of Florence, Hampshire County, State of Massachusetts, United
States of North America, temporily residing at the City of Manchester, in
the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date Twenty-eight day of December, in the year of our

page_text: Lord One thousand eight hundred and sixty, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the

vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN MACHINERY
FOR CLEANING, SORTING ACCORDING TO SIZE, AND DOUBLING SILK
THREADS," partly a communication from Goodrich Holland, of Windham,
County of Windham, and State of Connecticut, United States of North
America, and partly my own Invention and discovery, upon the condition
(amongst others) that I, the said Ira Dimock. by an instrument in writing,
under my hand and seal, 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 Great Seal Patent Office, within six
calendar months next and immediately after the date of the said Letters Patent.
AND OTHER
NOW KNOW YE, that I, the said lra Dimock, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement and accompanying Drawings (that is to say):-
My Invention relates firstly, to mechanism for cleaning silk, and consists
in mounting one jaw of a cleaner on an axis parallel to the space to be formed
between the jaws, and in causing the said jaw to be kept in its place when
operating upon the thread by a spring, by this means the space between the
jaws for the thread to pass through will be maintained parallel under every
variation of adjustment, and the moveable jaw may be readily withdrawn
from the fixed jaw to remove dirt, the spring bringing the moveable jaw
back to its correct position when permitted. This improvement is illustrated
by Fig. 1a front, and Fig. 2 a plan view of the improved cleaner.
a is the fixed jaw, which is secured to the rail of the winding machine by
screws a'; b is the moveable jaw which turns on the pivot b¹ secured in the
fixed jaw; cis the screw by which the space between the jaws for the thread
is adjusted; d is the spring which keeps the moveable jaw against the ad-
justing screw (c); and 62 is a projection from the moveable jaw to give hold
for the finger when opening the jaws to remove dirt or other matter left
between the cleaning edges.
My Invention relates, secondly, to machinery for sorting silk and other

page_text: thread according to size, which operation is technically termed "sizing thread,"
and refers to such machinery as operates in a manner similar to that described
in the Specification of the Patent granted to Alfred Vincent Newton, No. 1945,
and dated the Twenty-seventh day of August, in the year of our Lord One
thousand eight hundred and fifty-eight, according to which Specification the
thread guide for distributing the thread upon the bobbin is caused to be slided
upon the traverse bar, when a change in the thickness of the thread occurs by
two levers,and this part of my Invention consists in employing only one lever
in place of the two in combination with suitably shaped slots or grooves formed
in or attached to the slide of the thread guide. This part of my Invention is
illustrated in the accompanying Drawings by Figs. 3, 4, 5, and 6. Fig. 3 is a
front elevation, and Fig. 4 an end sectional elevation of a sizing machine,
and Fig. 5 shows a front or edge; and Fig. 6 a plan or flat view of a detached
part of the traverse guide. a is the excentrically mounted pulley described
in the aforesaid Specification of Alfred Vincent Newton; b is a lever, the
fulcrum (b) of which is mounted in centers carried by a bracket (A¹) from
the framing (A) of the machine; the lower end of this lever (b) is acted upon
by a cam (62) similar to one of the two described in the said Alfred Vincent
Newton's Specification; the upper end of the lever (b) enters a slot formed
in a piece (63) attached to the slide (6), carrying the thread distributing
guide (c.) The form of this slot is shown in Fig. 6. As long as the thread
is winding upon the middle bobbin, the end of the lever (b) is in that part of
the slot between the Figures 2 and 3 (Fig.6), when the thread is winding on
the bobbin (d) to the right of the middle bobbin (d), the end of the lever is
in that part of the slot between 1 and 2,and when the thread is winding on
that bobbin () to the left of the middle bobbin, the end of the lever is in
that part of the slot between 3 and 4. As long as the end of the lever (b)
keeps in a line with the straight side of the slot there will be no change in
the position of the thread guide, but should the lever be moved by the cam(b2)
connected with the excentric pulley (a), its end will catch on one of the
corners at 2 or 3 (see Fig. 6), as the case may be, and cause the thread guide
to be shifted in position on the traverse bar (c) accordingly. If changes are
about to take place in the direction from 1, 2, to 2-3, or from 2, 3, to 3-4,
(see Fig. 6), and the cam (62) connected with the excentric pulley (a) causes
the end of the lever (b) to move before it comes opposite those parts of the
slots marked 2 or 3 (as the case may be), then the lever (b) is sufficiently
elastic to spring over the pointed corners of the slot at 2 or 3. But, if thought
desirable, the upper part of the lever (b) may be jointed so that it can turn
or move back from the front of the machine, but not forward beyond a fixed

page_text: position, by which means the movements of the cam (62) connected with the
excentric pulley (a) will be unrestrained, and the upper end of the lever (b)
will be free to fall forward at the end of the slot when the movement of the
cam (62) permits it to move in that direction, thus avoiding the necessity for
elasticity in the lever (b.)
My Invention relates, thirdly, also to mechanism similar to that described
in the aforesaid Specification of Alfred Vincent Newton, when the thread in
place of being wound upon one long bobbin, as therein described, is distri-
buted upon separate bobbins (placed on the same axis or spindle), having thin
heads,the thread passing over these thin heads in changing from one bobbin
to another, the object of this part of my Invention being to diminish the
accumulation of the thread near the heads of the bobbins when the thread
guide is stationary, during the time the change is being made in its position
on the traverse bar, which accumulation of the thread renders more difficult
the finding of the ends of the thread, when the thread from the bobbins after
being separated has to be unwound from them; and this part of my Invention
consists in mounting the thread guide or an additional thread guide upon the
thread guide slide, so that the thread guide can be moved sideways, and in
arranging it so that when the thread guide slide is prevented from moving
with the traverse bar a notch, projection, or other suitable arrangement on
or in the traverse bar will become connected with and give motion to the
thread guide so as to move it (carrying the thread with it) in an opposite
direction to that in which the traverse bar is moving at the time the change
is taking place, the connection between the traverse bar and the thread
guide ceasing at the time or before the change in the position of the thread
guide slide is fully effected, so that time is given for a spring atttached to the
moveable thread guide to bring it back to the central or normal position.
Fig. 3 shows one "sizing head" with three bobbins (d, d', d²) upon
one spindle, and together with Figs. 5 and 6 will illustrate the mode of
carrying this part of my Invention into effect. A projection (65) is formed
upon the thread guide slide, in which a staple (6) is formed or secured
The additional thread guide (67) is carried in this staple, the smaller end
(see Fig. 5) passing through the staple, the shoulders upon the guide resting
on the two sides of the staple. The thread guide (67) is kept in the position
in which it is shewn in Fig. 5, by a spring (68) secured to the upright part(b5)
as shewn, which acts upon a pin (69) secured in the tail part of the thread
guide. The thread guide (67) so arranged is capable of being forced on either
side, one or the other side of the staple 6º) being the fulcrum according to
the direction. in which the force may be applied to the tail part of the thread

page_text: guide, and when the tail part is released, the thread guide will be brought by
the spring (8) to its vertical or normal position. When the thread guide (c¹)
is moving with the traverse bar (c) and distributing the thread, the tail
part of the additional thread guide (67) stands vertically over a notch formed
in the traverse bar (c), but if the thread guide slide is prevented from
moving with the traverse bar (as is the case when a change in the thickness
of the thread occurs), then the edge of the notch in the traverse bar (c),
forces the tail part of the additional thread guide (0) on one side, (by this
movement the thread is guided over the heads of the bobbins), and keeps
it in that position till it arrives at the next notch in the traverse bar (c),
when it again becomes erect by the action of the spring (6³).
My Invention relates, fourthly, also to mechanism similar to that described
in the aforesaid Specification of Alfred Vincent Newton, and its object is to
prevent, as far as possible, a thread, after a change in thickness has taken
place, from continuing to be wound on the same bobbin as that for the size.
previously indicated during the short space of time occupied in effecting the
change in the position of the thread guide, and this part of my Invention
consists in in arranging so that the length of thread between the guaging
mechanism and the bobbin on which the thread is wound will be equal, or
nearly so, to the length which will be wound in the time occupied between
the moment a change is indicated and that moment when the thread
passes
over the heads of the bobbins, taking an average of the time of effecting the
change and length of thread wound in that time. The required length of
thread may be obtained by causing the thread to descend from the guaging
apparatus, and then pass under a pulley, and then ascend to the bobbin
upon which it has to be wound. The manner in which this part of my
Invention is carried into effect is shown and illustrated by Figs. 3 and 4.
The thread to be sized passes from the bobbin between the guaging roller
(e) and excentric pulley (a) descending from the guaging roller (e) to a
pulley or roller (f) near the floor of the room, and then ascends, passing
through suitable guides to the thread guide and on to the bobbin.
My Invention relates, fifthly, also to mechanism similar to that described iu
the aforesaid Specification of Alfred Vincent Newton, and applies more particu-
larly when sizing fine threads, the object of this part of my Invention being to
reduce or remove the strain upon the thread caused by the friction or drag of
the guaging roller or rollers and pulley, and by the same means obviate the
necessity for a delicate adjustment of the weighted excentric pulley, thus
obtaining a quick action in the guaging mechanism when a change of thickness
in the thread takes place; and this part of my Invention consists in giving a

page_text: positive rotating motion to the roller or rollers, which have hitherto been driven
by the friction of the passing thread in the same direction, but a little faster
than the said roller or rollers would be driven by the passing thread alone.
This part of my Invention further consists in applying arrangements which
will retard the speed of the said driven guaging roller or rollers when the
thread becomes slack, and stop the roller or rollers when the thread happens
to break. This may be accomplished by a lever which carries a brake
surface near to its fulcrum, which will act to retard or stop the driven roller
when the lever falls in one position, but will allow the roller to rotate without
obstruction so long as the lever is held in another position. The positions of
this lever are governed by the thread, the end of the lever being sustained by
the thread, and if the thread becomes slack or broken, the lever will be
allowed to fall, and act as above described. This part of my Invention is
illustrated by Fig. 3. The guaging roller (e) has a warf or pulley fast upon
its axis, which is driven by a band g, working upon a warf on the shaft (g),
giving motion to the bobbins (d, d¹, d,) upon which the thread is wound.
In case the thread between the guaging mechanism and the thread guide
should become slack or break, the excentric brake surface (attached to the
lever g³, having its fulcrum (g) on a stud in the bracket carrying the
guaging roller (e) will act upon the periphery of the guaging roller (e), and
retard or stop its motion accordingly as the thread is slack or broken. As
the thread passes through an eye in the end of the lever (93) and a stationary
eye (g) above it, the lever (g³) is held in the vertical position, so that the
brake surface (9) does not touch the guaging roller (e) as long as the thread
is in sufficient tension. The advantages of this part of my Invention are
obtained when the rotating parts of guaging mechanism are assisted in their
rotation without being positively driven, as would be the case when the
drawing band is arranged to work on a warf or pulley loose on the axis of
the roller to be driven, but having friction tending to drive the roller in
the same direction in which it is rotated by the thread to be guaged. In-
stead of using a brake to retard and stop the guaging roller or rollers when
the thread becomes slack or broken, the lever may be arranged to carry an
antifriction pulley made to press upon the driving band and slacken or
tighten it as required, and when the thread breaks, the lever may be
arranged to catch upon a pin or notch in the guaging roller or rollers, and
stop their rotation.
Other means than the endless band may be used for
giving the positive or assisting motion to the rotating parts of guaging
mechanism, but I prefer the band as the simplest and least objectionable.
My Invention relates, sixthly, to a novel system of sizing or indicating the

page_text: changes in the thickness of threads, and consists in passing the threads to
be sized between surfaces which always remain at the same distance apart,
the space between them being sufficient to allow the thickest portions of the
thread to pass, while the thinner portions will pass more freely, the friction
of the passing thread upon the surfaces being in proportion to its thickness;
and in arranging these surfaces so that one or both of them will be carried
forward by the drag or friction of the thread when the friction increases, and
brought back by a weight or spring when the friction decreases, so that one or
both surfaces will move forward or backward according to the amount of
friction with which the passing thread acts upon the surfaces, and thus
indicate the thickness, and the changes in the thickness of the thread, the
movement produced by these changes being made to bring into operation
arrangements for stopping the winding of the thread, or for changing the
distribution of the thread according to its thickness. In carrying this part
of my Invention into effect a roller and pulley, similarly arranged to those
described in the aforesaid Specification of Alfred Vincent Newton, may be
employed, except that the pulley need not be excentric, the space between it
and the roller being the same in every position of the pulley. The roller in
this arrangement may be positively driven or assisted as described under the
fifth head of this Specification, otherwise a pair of rollers may be placed in a
frame or carried by a balanced lever, and one of the rollers may be assisted
in its rotations to take the strain off the thread passing between the rollers.
The roller which is not driven may have a small toothed pinion on its axis,
geeringwith a fixed toothed rack,and thus the latter roller will remain stationary
till an increased thickness of the thread gives friction sufficient to cause it to
rotate, and thus change the position of the frame carrying the rollers, which
frame is weighted so as to be brought back when the friction of the passing
thread diminishes, otherwise two surfaces may be arranged so as to come
within a fixed distance of each other, being kept in that position by a spring,
which will allow the surfaces to recede from each other when a knot has to
be passed, but will be practically rigid to the even portions of the thread,
these surfaces being carried on the end of a balanced lever weighted to
change in position according to the amount of friction put upon the surfaces by
the passing thread. It may be explained, that it is not necessary
in every
case that the surface which is carried forward when the friction increases, by
reason of the increased thickness of the thread, shall go backward when the
friction diminishes by reason of the diminished thickness of the thread, as the
surfaces employed may be a pair of rollers, one of them being so arranged as
only to revolve when the thread is thick, ceasing to revolve when the thread

page_text: becomes thin, arrangements being applied which will be acted upon by the roller
when it begins and when it ceases to revolve, and thus indicate the changes
in the thickness of the thread, and communicate the required movements to
the mechanism, which stops the bobbin on to which the thread is being wound,
or adjusts the thread guide so as to wind the thread on the proper bobbin.
The manner in which this part of my Invention is carried into effect is illus-
trated by Figs. 3, 7, 8, 9, 10, 11, and 12, which are also intended to illustrate
the improvements to be herein-after described under the seventh head of this
Specification. When sizing thread according to this part of my Invention
and by arrangements similar to those described in the said Alfred Vincent
Newton's Specification, I arrange the pulley (a) so as to be perfectly central,
and so that the same amount of space will exist between its periphery and that
of the guaging roller (e) in every position of the pulley (a), and instead of
weighting the pulley with one weight, as described in the said Alfred Vincent
Newton's Specification, or a weight gradually increasing according to the
position of the pulley, I prefer to employ two or more weights according to
the number of sorts or sizes into which the thread is to be separated, and I
arrange these weights so as to be taken up by the pulley as it turns in succes-
sion. This is illustrated in Fig. 8, a detached view of guaging mechanism.
One end of a chain (7) is attached to a circular flange on the guaging pulley
(a), the other end to a rod (¹) formed with two or more shoulders. This rod
passes through holes in two or more (as required) disc weights (2). If the
rod descends below the position in which it is shewn in Fig. 8, there will be
no weight acting upon the pulley (a) but that of the chain aud rod which
represents the least size of thread, as the other weights will be carried by the
bracket (3); but if the rod (h¹) ascends, the first shoulder upon it will lift
one weight, and if it continues to ascend the next shoulder on the rod will lift
the next weight, and so on, as will be readily understood. In other respects
than those above mentioned the arrangements which I employ in carrying
out this.part of my Invention are the same as those described in the said
Alfred Vincent Newton's Specification, or as when altered by the improve-
ments herein-before described; but the movements produced by the cam (63)
connected with the guaging pulley (a) may be made to stop the winding of the
thread instead of changing the traverse guide, if required, in a manner
which will be readily understood from the explanations herein-after given.
The manner of carrying this part of my Invention into effect when rollers in
an oscillating frame are used is illustrated by the right-hand sides of Figs. 3
and 7, and the detached view Fig. 9, Fig. being a front and Fig. 7 an end
sectional elevation. These views are also intended to illustrate the mode of

page_text: carrying into effect the improvements to be herein-after described under the
seventh head of this Specification. In Figs. 3, 7, and 9, four rollers are sup-
posed to be shown in the frame, but two only will be spoken of in illustrating
the mode of carrying out this part of my Invention. The construction of the
frame or lever k, carrying the rollers, will be best understood by reference to
Fig. 9. The frame or lever k, and rollers, and other parts, must be made as
light in weight as possible consistent with the requisite strength. The axis (¹)
of the lever frame () is supported by adjustable screw centres fitted into
brackets from the framing (A) of the machine. The rollers may be mounted
on studs fixed in the frame, or on adjustable centre screws, and one of the
rollers may be arranged so as to be moveable, and so that the space between
the rollers may be adjustable, which may be done in a manner similar to that
by which the roller 4 is made adjustable to the other rollers (as shown in
Fig. 9), by being carried on a separate arm from the axis (¹) sufficiently
flexible in the required direction to allow of the small amount of adjustment
required. The point of the adjusting screw(2) being kept against that part of
the lever frame () upon which it acts by an india-rubber or other spring (k³).
The boss of the roller (1) has a small toothed pinion upon it, which geers with
a toothed rack carried by the arm k from the framing. Two arms (k³)
extend from the axis (4),which are intended to balance the frame and rollers,
and to carry a weight (), which will rest at times on supports from the
framing, the object of which weight will be more particularly described
herein-after. From the axis of the lever frame (k) two upright arms and k³
also extend (best seen in Figs. 3 and 7), the ends of which are formed so as
to catch when the thickness of the thread changes upon projections in the
spindle of the bobbin upon which the thread is being wound, so as to stop its
rotation. It is intended to make three sizes of thread, fine, medium, and
coarse, and for the purpose of explanation it may be supposed that the lever
frame is balanced so as to stand in the central position in which it is shown
in Fig. 7. Then such a weight (k) is added to the opposite side of the axis
() from the roller as shall be equivalent to the drag or friction produced by a
change from medium to coarse thread. Then twice as much weight is added
to the opposite or roller side of the axis (¹), so that the roller side of the
lever frame will preponderate by the weight equal to the drag or friction pro-
duced by a change of thread from fine to medium; the roller end of the lever
frame when thus balanced and unrestrained descending to its lowest position.
The thread to be sized passes from the bobbin (i) past the rod (i) through the
guide eye (2), between the guaging rollers,through the thread guide (c) in the
traverse bar (c), and on to the bobbin (d). When the thread is fine it will pass

page_text: between the rollers without acting upon them,so as to produce a movement of
the lever frame (k). When the thread changes to medium it will exert suffi-
cient friction to lift the lever frame to the central position; and when it
changes to coarse it will exert an additional friction equal to the weight
(6) on the arms (5), which weight is left on the supports from the framing
when the roller side of the lever frame ascends above the central position.
Every change in the lever frame (k) from any one of the three positions in
which it may be in to any other of the positions stops the winding of the
thread upon the bobbin, upon which it may be winding previous to the change
taking place in the thickness of the thread; and one peculiar and novel
feature ofthestopping arrangements consists in preventing the substitution of
the wrong bobbin, as the arrangement so acts that the winding and sizing
process cannot be proceeded with till the right bobbin is used. The two
upright arms (c and for stopping the rotation of the bobbin are at an equal
distance from the spindle of the bobbin on which the thread is being wound
when the thread is of medium thickness; but should it increase or decrease in
thickness, either one or the other arm ( or ) will catch upon the broad
projection from the spindle of the bobbin; if the thread has increased in
thickness, then the bobbin for the coarse thread can only rotate, as the stop
arın () will rest against the spindle, and the projection in the spindle of the
coarse thread bobbin will pass the end of this arm; but neither of the pro-
jections on the spindles of the fine or medium bobbins will so pass; the same
is the case when the change is from coarse to medium or fine thread, then
neither the projection on the spindle of the medium or coarse bobbin will pass,
as the stop arm (7) will then be against the spindle. The two stop arms
(and) are not set opposite, but on one side of each other, so that one arm
will catch when the changes are increases, the other when the changes are de-
creases in the thickness of the thread. In using the lever frame with rollers for
sizing thread, a portion or as much as required of the friction or drag upon the
thread in passing between the rollers may be removed by assisting the rotation
of the roller 2, by mounting it upon a spindle (°) in the lever frame k, and
placing a warf loose upon the spindle so as to come in the centre or axis ()
of the lever frame (k) (see Fig. 9), and driving this warf by a band, I, from
the shaft (g'), as shown in Fig. 3, so that the friction of the rotating warf will
assist or help the drag of the thread to give rotatory motion to the roller (2.)
The roller 1 does not rotate always in the same direction, but only oscillates
or turns backwards and forwards according to the changes in the thickness of
the thread, thus causing the pinion to ascend and descend the toothed rack,
and effect the changes in the position of the lever frame (k.) The method o

page_text: sizing thread according to this part of my Invention by fixed surfaces is illus-
trated by the middle part of Fig. 3, the left hand side of Fig. 7; and the views
of the surfaces employed and their case detached are shown by Fig.10 a side,
Fig. 11 a front, and Fig. 12 a sectional view. These Figures also serve to
illustrate those improvements to be herein-after described under the seventh
division of this Specification. The construction and arrangement of the
surfaces for guaging the thread will be best understood by reference to
Fig. 12. is a small cylinder or case having a recess or shoulder formed at
each end; in each recess is fitted a disc l'having shoulders which prevent them
from being forced too far into the cylinder or case by the spring 12, which is
arranged as shown; circular discs, with their edges rounded off, are placed
in the cylinder (1) between the two end discs (7), and a pin is passed
through holes in the discs, as shown in Fig. 11, to prevent the central discs
from falling out at the space cut out of the side of the cylinder (1); a space is
left between the inner discs for the thread to pass through, which space is
constantly the same,and does not increase or decrease or open except to allow
a kuot or lump on the thread to pass through, when the spring (22) will extend
and allow the discs (11) to come outwards; but so far as the sizing operation
is concerned the discs are practically rigid and immoveable. This cylinder or
case and the discs are carried on the end of au arm from an axis ¹, which
is centered and balanced and weighted in the same manner as the lever frame
(), carrying the rollers (1, 2, 3 and 4.) The thread to be sized passes from
the bobbin (i) past a guide rod i¹, between the discs (13), through the thread
guide (c), on the traverse bar (c), and on to the bobbin (d). Any increase or
decrease in the thickness of the thread will cause an increase or decrease of
friction on the surfaces, and thus a change in the position of the lever le, which
will stop the winding as herein-before explained in describing the lever frame
() and rollers. It will be understood that the movements produced by sizing
or guaging mechanism can readily be made as required, either to stop the
winding, or shift the thread guide, as herein-before explained.
My Invention consists, seventhly, in a system and arrangements for sizing
and at the same doubling threads so as to produce doubled or compound
thread of uniform thickness, or so as to sort compound threads according to
thickness, which will be produced with fewer piecings of the thread than
when the threads are first sized and then doubled by the ordinary process, as
the deficiency of thickness of one of the threads will frequently be compensated
by the excess of thickness of the other threads forming the doubled or com-
pound thread. If I wish to produce acontinuous compound thread of uniform
thickness I cause the mechanism to stop the winding every time there is a

page_text: change in' the thickness of the compound thread, and substitute for one or more
of the single threads other threads of suitable thickness, according as it may be
in excess or deficiency in the compound thread, or I wind the compound thread
on to bobbins according to thickness. I guage or size each single thread
forming the compound thread between separate rollers or surfaces, but
arranged so that an increase or decrease in the sum of the thickness of the
threads only will be indicated. This part of my Invention may be carried
into effect by similar mechanism to that described in the aforesaid Specification
of Alfred VincentNewton, except that for every single thread in the compound
thread a separate roller or pair of rollers will have to be added, arranged so
that the rollers will act upon each other directly or by means of connections
between their pivots and the roller nearest the oscillating pulley, which will
thus be affected by any increase or decrease in the sum of the thicknesses of
the threads passing between the rollers. Otherwise this part of my Invention
may be carried into effect by arrangements similar to those described under
the sixth head of my present Invention, by adding as many surfaces or rollers
or pairs of rollers as there are threads in the compound thread.
Talso combine with my improvements in sizing and doubling the common
mechanism for detecting the absence of any of the single threads forming the
compound thread, and stopping the winding when this occurs.
Fig. 8 illustrates how this part of my Invention may be carried into effect
by a modification of the Invention described in the aforesaid Specification of
Alfred Vincent Newton, or when that Invention is modified by operating by
friction only,as herein-before explained under the sixth division of this Speci-
fication. The dotted lines (a) represent two threads, for which two additional
rollers (e¹,e2,) are added mounted in centers, so as to be capable of moving to
and from each other, and the outside roller (e) and pulley (a) which are fixed
in position so far as the guaging operation is concerned. The sum of the two
spaces left for the threads between the rollers e, e¹, and roller e², and the pulley
(a),will increase and decrease according to the thickness of the threads if the
pulley (a) is excentric; but if concentric the sum of the spaces will be uni-
formly the same; in either case the pulley (a) will change in position according
to the changes in the sum of the thickness of the threads, and thus stop the
winding, or shift the thread guide (cl) upon the traverse bar (c), accordingly
as it may be arranged.
The other methods of carrying out this part of my Invention by the use of
rollers or fixed discs are illustrated by Figs. 3, 7, 9, 10, 11, and 12, the only
difference between the arrangements forsizing and doubling and that for sizing
single threads is, that additional rollers or surfaces are required, according to

page_text: the number of threads to be sized and doubled at the same time. The rollers
2 and 3 (Fig. 9), are made to fit easily upon their studs, which is quite a suf-
ficient provision for their movement to and from each other and the rollers 1
und 4. The dotted lines a represent the threads passing from the bobbins (i)
through eyes in the detecting wires or levers ; (centered on a shafty', carried
by brackets from the framing) between the guaging surfaces or rollers, through
the thread guide c', and on to the bobbin (d, or d', or d³); if the thread breaks
the detecting levers ; fall upon a balanced lever (3), which by means of a
connecting rod 3 lifts another lever j4, so that its end will catch upon the
projections from the spindle of the bobbin and stop it. This mechanism is
only shewn on the right-hand side of Fig. 7, in dotted line.
