1 HENRY HARRIS LAKE of the firm of Haseltine Lake & Co. Patent Agents,
Southampton Buildings in the County of Middlesex, do hereby declare the nature
of this invention to be as follows:-
My improvement relates to machines for filling quills employed in weaving.
In my improvement I employ a main shaft mounted in a frame and deriving motion
from any desired source, preferably from a loom to which the frame may be attached.
In the frame is also mounted a rotary flier deriving motion from the main shaft. A
longitudinally reciprocating but non-rotary quill spindle is employed. This quill spindle
slides in bearings also formed in the frame. Two movements are imparted to the quill
spindle and to the quill thereon when the quiller is in operation; one a constantly
reciprocating motion and the other a continuous lengthwise movement in one direction.
Both these movements occur simultaneously and are effected through the interventions
of mechanisin operated from the main shaft.
For the better understanding of my improvement I will further describe a machine
embodying it.
On the main shaft is a worm which engages a worm-wheel. When the main shaft
is rotated the worm wheel will be also rotated and will transmit motion to a cam.
The can actuates a lever or levers having a connection with the quill spindle near one
end of the latter. The operation is such that as the cam is rotated the quill spindle is
caused to be moved a short distance longitudinally in one direction. A weight or its
equivalent is employed for moving the quill spindle in the opposite direction.
By these means a constant reciprocating motion is imparted to the quill
spindle.

page_text: By the rotation of the cam above referred to motion is caused to be given to a
ratchet wheel mounted upon a shaft upon which is also mounted a worm which
latter engages
a worm wheel whereby motion is transmitted to a second cam. This
latter cam is by preference a snail cain. It in turn operates a connection with the
spindle or an appurtenance thereof to effect a practically continuous movement of the
quill spindle and quill thereon in one direction.
When the quill spindle and quill have been moved sufficiently far in this direction a
stop motion is operated automatically to stop the machine. This stop motion is
operated by the sudden return of the quill spindle to a position to receive a new or
empty quill.
In connection with the quiller I may employ a let off mechanism whereby the thread
passing to the quiller may be twisted or untwisted to suit the requirements of the
weaver. This let off mechanism will preferably be mounted upon the frame of the
quiller and will be operated from the main shaft thereof. It consists in a spool carrying
shaft adapted to be rotated in different directions and a flier. Thread passes from the
spool to the quill on the quill spindle. By rotating tho shaft upon which the spool is
carried at any proper rate of speed the twist of the throad which is being supplied to
the quill may be altered.
By the use of this apparatus I effect a novel method of preparing filling or tram ;
I group together in an untwisted state, the entire number of threads or groups of
threads of which the tram is to be composed and twist them together for the first
time that they are twisted. The twist may be varied in the manner described.

Improvements in and relating to Apparatus for Winding Thread
upon Quills.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex 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 :-
My improvement relates to machines for filling quills employed in weaving.
In my improvement I employ a main shaft mounted in a frame and deriving motion
from any desired source, preferably from a loom to which the frame may be attached.
In the frame is also mounted a rotary flier deriving motion from the main shaft. A
longitudinally reciprocating but non-rotary quill spindle is employed. This quill
spindle slides in bearings also formed in the frame. Two movements are imparted to
the quill spindle and to the quill thereon when the quiller is in operation; one a
constantly reciprocating motion and the other a continuous lengthwise movement in
one direction. Both those movements occur simultaneously and are effected through
the interventions of mechanism operated from the main shaft.
For the better understanding of my improvement I will further describe a machine
embodying it.
On the main shaft is a worm which engages a worm wheel. When the main shaft
is rotated the worm wheel will be also rotated and will transmit motion to a cam.
The cam actuates a lever or levers having a connection with the quill spindle near one
end of the latter. The operation is such that as the cam is rotated the quill spindle is
caused to be moved a short distance longitudinally in one direction. A weight or its
equivalent is employed for moving the quill spindle in the opposite direction. By
these means a constant reciprocating motion is imparted to the quill spindle.
By the rotation of the cam above referred to motion is caused to be given to a

cam is by preference a snail cam. It in turn operates a connection with the spindle
or an appurtenance thereof to effect a practically continuous movement of the quill
spindle and quill thereon in one direction.
When the quill spindle and quill have been moved sufficiently far in this direction
a stop motion is operated automatically to stop the machine. This stop motion is
operated by the sudden return of the quill spindle to a position to receive a new or
ompty quill.
In connection with the quiller I may employ a let off mechanism whereby the
thread passing to the quiller may be twisted or untwisted to suit the requirements of
the weaver. This let off mechanism will preferably be mounted upon the frame of

carrying shaft adapted to be rotated in different directions and a flier. Thread passes
om the spool to the quill on the quill spindle. By rotating the shaft upon which tho

page_text: spool is carried at any proper rate of speed the twist of the thread which is being
supplied to the quill may be altered.
By the use of this apparatus I effect a novel method of preparing filling or tram ; I
group together in an untwisted state, the entire number of threads or groups of
threads of which the tram is to be composed and twist them together for the first time
that they are twisted. The twist may be varied in the manner described.
In the accompanying drawings, Fig. 1 is a front view of a quiller embodying my
improvement. Fig. 2 is a side view of the same. Fig. 3 is a vertical section taken
as indicated by the line xx, Fig. 1, but on a larger scale. Fig. 4 is a side view of
certain parts, and Fig. 5 is a side view of certain other parts. Fig. 6 is a side view
showing a modification of certain parts, certain other parts being omitted or broken
away for the sake of clearness. Fig. 7 is an edge view of the same. Figs. 4 and 5
are drawn to the same scale as
Fig. 3.
Similar letters of reference designate corresponding parts in all the figures.
A designates the frame of the quiller. As shown, it consists, essentially, of a flat
part, a, adapted to be secured by bolts B or other means to the frame of a loom or to
any other suitable support, and curved end portions, a', which constitute means for
supporting the various parts comprised in the quiller.
O designates a shaft, which in the present example of my improvement occupies a
vertical position, and is journaled in the end portions of the frame A. This is the
principal shaft of the quiller. It is provided with a fast pulley, A', and a loose
pulley, A. Combined with these pulleys is a belt-shifter, A³, consisting of a lever
fulcrumed to a pin or stud, a³, which extends from the frame A, and having a fork at
the end which extends into proximity with the pulleys A¹ A2, and having the othor
end provided with a lug, a', which extends approximately parallel with the pin or
stud a³, or, in other words, which extends rearwardly from the lovor.
A designates a spring, which is fastened at one end to the frame A, coiled around
the stud or pin a³, and at the forward end, engaged with the arm of the lever which is
provided with the lug at. This spring tends to oscillate the lever so that its fork will
shift the belt which is employed in connection with the shaft C on to the loose
pulley A. The spring will always adjust the lever so as to cause it to shift the
belt on to the loose pulley, except when said spring is prevented from actuating the lever.
D designates an elbow or bell crank lever fulcrumed at the middle to a pin or stud, d,
which is affixed to the frame A. The upwardly extending arm of this lever is
provided with a notch, d', which is capable of receiving the lug, at, of the belt shifter
lever. The laterally extending arm is provided with a slot, through which a rod, D',
loosely extends.
After the belt shifter lever has been adjusted, by manipulating the arm which is
provided with the lug, a', into such position that its forked end will shift the belt on
to the fast pulley a¹, the lever D will engage with the lug, at, of said belt shifter
lever, and thereby lock the latter in position. While the belt shifter lever occupies
this position, the shaft C will of course be continuously rotated.
The rod D' is provided with two collars, dd, which preferably are adjustable
lengthwise of the rod. As shown, they are provided with set screws d*, whereby
they may be clamped in position upon the rod after having been properly adjusted.
One of the collars, d, is above the arm of the lever D, which receives the rod D'.
The other collar, d, is below the lever D. The rod D' normally hangs from the
laterally extending arm of the lever D. It serves as a weight whereby the lever D
will have a tendency to rock into a proper position to engage with the lug a* of the
belt shifter lever whenever the latter shall be adjusted into such position as to bring
its said lug at opposite the notch d' of the lever D. Whenever the rod D is moved
upwardly to such an extent as to bring its collar into contact with the laterally
extending arm of the lever D the lever D will be rocked in such direction that its
notch d' will be disengaged from the lug at of the belt shifter lever. When this
happens the spring A will rock the belt shifter lever so as to cause it to shift the
belt from the fast pulley A¹ to the loose pulley A2, in order that the quiller may stop
operating.

page_text: The manner in which the rod D¹ is adjusted upwardly for the purpose just
mentioned will be fully described hereinafter.
The upper end of the shaft C extends into and through a box like portion a², of the
frame A, and within said box like portion the shaft has affixed to it a gear-wheel C.
This gear-wheel C₁ engages with a smaller gear-wheel E¹, which is affixed to a
tubular shaft, E, forming the shank of a flier, EE². The arms E² of the flier extend
in opposite directions from the shank E, thence downwardly, and thence toward each
other, in the ordinary manner. The shank E of the flier is journaled in the box-like
portion of a of the frame A, and its gear-wheel E' is contained within said box-like
portion.
F designates a frame mounted upon the top of the box-like portion a³ of the
frame A, and is adapted to receive a shaft, F', upon which is mounted a spool of
thread or yarn which is to be formed into a quill.
F2 designates a brake consisting of a lever fulcrumed at one end to an extension
of the frame F, bearing at the other end upon the thread or yarn which is wound
upon the spool, and having hung from it between the ends, a weight, serving to
produce the requisite tension upon the thread or yarn daring its passage from the
spool. Leaving the spool, the thread or yarn passes through an eye, F³, thence
through the hollow or tubular shank E of the flier, and thence through one of the
arms of the flier. By the latter it is wound around a quiller rod to form a quill.
It will be understood that by means of the gear-wheels CE¹ the shaft C effects
the rotation of the flier. Obviously the rotation of the flier will always bear a fixed
relation to the rotation of the shaft C.
G designates the quill spindle. Each quiller rod Q* to be wound is fitted to and
temporarily secured upon this quill-spindle. The quill-spindle extends through a
bearing a, forming part of the frame A. It will be observed that the quill-spindle
extends upwardly, and the flier extends downwardly in the present example of my
improvement. The quill-spindle does not rotate, but has a longitudinal movement
relatively to the flier. At the lower end it has extending laterally from it a pin or
projection, G. To the pin or projection G¹ is fastened a cord G². This cord G
passes over a pulley, G³, that is mounted loosely upon a stud extending from the
frame A, and at the lower end said cord has a weight, G4, fastened to it. The
weight G moves the quill-spindle upwardly, whenever permitted to do so, by the
devices which control the movements of said quill-spindle.
I will now describe the means whereby the longitudinal movements of the quill-
spindle are controlled.
Near the lower end the shaft C is provided with a worm, H, which is securely
affixed thereto. This worm engages with a worm-wheel, H', that is rigidly affixed
to a shaft H³, arranged at right angles to the shaft C, and supported in a bearing
forming part of the frame A. The shaft H2 has also rigidly affixed to it a cam, I,
which operates upon a
lever, I. This lever at one end is provided with an anti-
friction roller or bowl adapted to bear against the cam I, and at the other end is
fulcrumed to a stud, a, affixed to an extension a', of the frame A.
J designates another lever fulcrumed at one end to a hanger, J. The hanger J¹ is
pivotally connected at the upper end to the stud a", which forms the fulcrum for tho
lever 1. The lower portion of the hanger J¹ is longitudinally slotted, and lever J is
connected to the slotted portion of the hanger by means of a bolt and nut J2. Owing
to the slotting of the hanger provision is afforded for adjusting the fulcrum of the
lever J, consisting of the bolt J vertically toward or from the fulcrum a of the
lever I', as may be necessary, in order to secure the desired operation of the lever J.
The outer end of the lever J is pivotally connected to the pin or projection G¹,.that
extends from the lower end of the quill-spindle.
The lever I has a hanger, I', extending from it. This hanger I is connected
by a bolt and nut with said lever, being preferably slotted longitudinally where the
bolt passes through it, so that the hanger may be adjusted to the desired relation
with the fulcrum of the lever. The hanger I is longitudinally slotted throughout
the greater portion of its length. This hanger has secured to it a bracket, K. Part

page_text: of the bracket K extends through the slot of the hanger. A bolt or screw K¹ passing
through the bracket, then through the slot of the hanger, and also through a nut or
block on the opposite side of the hanger, serves to secure the bracket in place upon
the hanger. The slotting of the hanger provides for adjusting the bracket to a
nicety.
The bracket K supports a shaft L, which extends approximately at right angles to
the shaft C. This shaft L has affixed to it a ratchet-wheel, L. Adjacent to the
ratchet-wheel an elbow or a bell-crank lever, L2, is loosely hung. One arm of this
lever has a pawl, L³, pivotally connected to it. This pawl is weighted so that it will
be caused to engage with the ratchet-wheel. The other arm of the lever has a
block, L, loosely mounted upon it, but held in place between a shoulder and a
cross-pin. A pin, L, extends through this block, L, and also through a block, L®,
which is loosely mounted upon a rod, L', but held in place thereon by two cross-pins
extending through such rod above and below it. The pin L' is loose in the
blocks LL, hence the said blocks are pivotally connected together.
The rod L' extends upwardly to the crank L³, which is affixed to the shaft H³.
This crank is shown as being affixed to the shaft H' through the intervention of the
cam I. I mean by this that instead of being directly secured to the shaft it is secured
to the said cam, which is a fixture on the shaft. As shown, the crank has a slotted
portion, h, which rests upon a block that extends from the forward side of the cam I.
A screw, ', passing through the slotted portion of the crank and entering the block
of the cam, fastens the crank in place. The wrist or pin of the crank Le, has loosely
mounted upon it a block, l. This block is retained in place upon the wrist of the
crank by means of a shoulder on one side and a cross-pin on the other side. The
rod L' has affixed to it a pin, 1, which enters the block 1, so as to be pivotally
connected thereto. It will be obvious that the block is therefore pivotally connected
with the rod L' as well as to the crank L. The pin is provided with a hole
whereby it is adapted to fit upon the rod L'. It is also provided at one end with a
set screw extending into a tapped hole which intersects the hole of the pin which
receives the rod L. This set screw serves to secure the pin upon the rod, and
provides for the adjustment of the pin into different positions lengthwise of the rod
and for securing it when adjusted.
The crank L imparts motion to the rod L, and this in turn oscillates the lever L',
causing the pawl of the lever to impart a partial rotary motion of the ratchet
wheel L', and hence of the shaft L. The extent of the motion thus imparted to the
shaft L, inay be varied as circumstances may require-as, for instance, to adapt the
quiller to threads or yarns of different sizes or to the production of quills of different
sizes by adjusting the point at which the crank L is connected to the cam I or
shaft H and the point of connection between the pin and the rod L.
On the shaft L is a worm L10, which engages with a worm-wheel, I", mounted
upon a shaft, L. The shaft L" is journaled in a portion of the bracket K, and has
affixed to it at the rear end a cam, M. The cam M is shown as of the kind which is
known as a "snail-cam." It operates upon a bearing, j, which is affixed to the
lover J. This bearing is affixed to the lever by means of a screw, j', which passes
through a longitudinal slot in the lever. This screw, j¹also secures to the lover a
guide,, made in the form of a bowl or roller, which extends through the slot of
the hanger I³.
The hanger I is not connected to the lever J by means of the guide, but is
merely kept in proper relation therewith. Hence in the operation of the quiller the
lever J, may swing relatively to the hanger, I', without affecting the latter.
The cam I rotates with sufficient rapidity to allow the quill-spindle to move upward
and cause it to move downward in the proper manner for the flier to wind the thread
or yarn in layers on the quill. This cam acts on the quill spindle by actuating the
lever I', for when the lever I' is actuated the cam M (which is carried by the lever 1,
owing to the connection of the hanger l' with this lever) operates the lever J
correspondingly, except that, owing to the rotation of the cam if, it will impart to
the lever Ja downward motion, which will be additional to the motion which said

page_text: lever J would receive from the cam I alone. The cam M, however, moves very
slowly, owing to the pawl-and-ratchet movement, and the worm and worm-wheel,
whereby motion is transmitted to said cam on the shaft H2, which carries the cam I.
The result of the movements imparted by the cams I and M to the lever J is
a reciprocating upward and downward movement of the quill-spindle and a pro-
gressive downward movement of said spindle. Owing to this the different layers
of the thread or yarn wound upon the quill will begin and end at different
points in the length of the quill. The shape of the cam I is such that the
lever J will move at different portions of its swing or oscillation at different
rates of speed. This will be advantageous, because the winding of the thread or
yarn in one direction on the quill will be or form a convolution of quicker pitch
that will cross the thread or yarn wound in the reverse direction upon the quill
and bind or secure it in position on the quill. The cam M makes one rotation
for cach quill which is wound. As soon as that peripheral portion of the cam M
which is of greatest projection passes the bearing j of the lever J the portion of
said can having the least projection comes opposite said bearing, and thereupon
the weight G quickly raises the lever J until the bearing j is brought into
contact with the portion of the cam M having the least projection. During this
movement the quill spindle will of course have a corresponding upward movement
imparted to it. The object of this movement of the lover J and quill-spindle is to
stop the quiller. I will now describe how this is effected. The pin or projection G¹
at one end is provided with a slot, through which the rod D¹ extends. This rod D'
Whenever the quill-spindle is
near the lower end is provided with a shoulder d³.
moved sufficiently far downwardly by the combined action of the cams I and M the
edges of the slot in the pin G¹ will move below the shoulder d' of the rod D¹. It will
be observed that this rod D' is maintained at a slight incline by the pin or projection G'.
Obviously, therefore, it has a tendency to assume a vertical position. This tendency
causes it to swing in such direction that when the slotted portion of the pin G¹ descends
below the shoulder do, the rod will swing and its said shoulder will lap over one of the
edges of the slot in the pin or projection G'. The upward movement of the quill
spindle, which next succeeds the engagement of the pin or projection G¹ with the
shoulder of the rod D³, will cause the rod D' to ascend also. Then the collar d³ of
said rod will strike the lever D and oscillate said lever, so as to disengage it from the
belt-shifter lever A³. When this occurs the latter will shift the belt on to the loose
pulley and the quiller will stop operating.
The provision for the adjustment of the crank L³ with relation to the shaft that
carries it and with relation to the rod L' affords provision for varying the speed at
which the cam M will rotate relatively to the speed of the cam I, and also relatively
to the speed of the flier E E. As the time during which the quiller will remain in
operation is dependent upon the time occupied by the cam M in making a rotation, it
will be obvious that by affording provision for varying the time in which the cam M
will make a rotation I provide for adapting the quiller to operate properly with threads
or yarns of different sizes. This is important, because obviously a thread or yarn of
smaller size will require more winding than a thread or yarn of large size in order to
produce a quill of desired size. And, again, where quills of different sizes are to be
made there is advantage in the provision for varying the time in which the cam M will
make a rotation.
It is to be observed that the adjusting mechanism which I have described does not
vary the operation of all parts of the quiller, but varies the time that the quiller
will remain in operation without producing any variation of the speed of the flier or
the speed of the longitudinal reciprocations of the quill-spindle.
Although I have shown the cam M as operating upon the quill-spindle through the
agency of a lever, J, arranged between it and the quill-spindle, yet it is obvious that
the lever is not indispensable to the desired operation of the quill-spindle by the said
cam. For instance, if the cain were made sufficiently large it might operate directly
upon the pin or projection G¹. To facilitate this, this pin might have an extension
toward the cam, as shown in Figs. 6 and 7
