I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E. of the Agency for Foreign
Patent Solicitors, 6, Lord Street Liverpool and 6 Bank Street Manchester both in the
County of Lancaster and 323 High Holborn in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention to be as follows :-
This invention relates to improvements in take-up mechanism for looms, the object
thereof being to provide a mechanism adjustable as to the parts thereof and intervening
between the lay-frame and the take-up roll or cloth-beam, whereby, in the running of
the loom for the making of any desired grade of cloth, the take-up roll, through said
adjustable connections, will have a rotation and peripheral movement exactly corre-
sponding to the production of the cloth by the loom.
On the frame of the loom is mounted a short horizontal shaft which, through
suitable gearing, is connected to the take-up roll or cloth-beam of the loom with
which take-up roll the fabric produced in and passing from the loom is to have a
frictional contact by any suitable means as by pressure and guide rolls, and as
common or to be found desirable and on said short shaft is loosely mounted a pulley
and also on said shaft, alongside of said pulley, is loosely mounted a driver-lever, the
action and purpose of which driver-lever is to engage, when swung in one direction,
the rim of said pulley to turn it, but, when swung in the reverse direction, to pass
freely over the rim of said pulley without effect thereon, the driver lever being
provided with suitable pawl or other description of engaging devices for engaging said
pulley. The pulley is to be provided with one or more spring-pressed, or other
description of pawls, or detents, independently of which it may freely move forward
under the action of the driver-lever, but said pawls act to prevent any retrograde
movement of the pulley when the driver retraces its movement.
On the shaft on which the lay-frame is supported and which shaft oscillates as the
lay frame swings, is fixed a radial arm between which and the said driver lever is a
link connection, the engagement of which link by its one end with the radial arm of
the lay shaft is adjustable, whereby, by changing the point of connection, the per-
pendicular distance between the said arm and the driver lever may be varied, and so
that, therefore, on a given throw of the radia! arm of the lay frame, a greater or less
swing of the driver may be effected to secure a movement of the pulley and, through
the proper intervening connections, of the take-up roll or cloth beam, to correspond to
the production of cloth by the loom.
The adjustable connection between the radial arm on the lay frame and the link
may be made as follows:-
The said arm has a longitudinal slot therein extending from near its hub to within
a short distance of its outer end where it is formed with a cross web of hub form
having a central bore in the direction of the length of said slot. A block fits to slide
in said slot having at its one end a head and at its other it is necked down and
outwardly extended in a spindle projection of reduced diameter.
The central body portion of the block portion just described is of slightly less length
than the width of said slot walls. A sleeve having at its inner end an outwardly
extending flange lies loosely upon said necked down spindle projection, and over said

page_text: sleeve fits the hub of one end of the link the same being held in place by a nut
screwing onto the end of the block spindle projection.
A similar form of connection to the one described may be employed for uniting the
other arm of the link with a suitable purt of, or fixture connected to and forming part
of the driver. By tightening the nut the sleeve flange is forced against one side of
the lever and the head of the block is drawn hard against the other side of said
lever arm.
On unloosening the nut, the block, and with it the connected end of the link,―is
free to be moved up or down in its guiding slot and a practical and efficient means for
so moving said block, and securing a minute adjustment thereof for regulating
the throw of the driver, may consist in forming in the said block a vertical screw-
threaded opening with which engage the threads of a vertical screw-rod having
a shoulder beneath the hub web at the end of said arm, said rod being by an
unthreaded portion thereof projected upwardly through and beyond the bore of said
hub web receiving and having fixed thereon a head bearing on the upper and outer
end of said hub web and having a knurled rim whereby it and the screw-rod may be
conveniently turned.
In order that the link connection between the radial arm of the lay frame and the
driver may act evenly and without any tendency to lateral or torsional draught
on either of said parts, whereby they would be strained out of a vertical plane
for their most efficient operation, a duplicate link is provided, by each of its hub
ends loosely fitting over the circular and somewhat diametrically reduced portion of
the head of each of the blocks. The said duplicate link is held against its fellow and
in its bearing on the circular heads of said blocks by a bolt passed through an
intermediate part of each of said link members, and retained in place by a nut.
This invention comprises, in addition to features already set forth, improvements in
the construction and arrangement of the pawls employed to engage the rim of
the intermittently rotated pulley and of the springs to maintain said pawls in their
operative relations, and these spring and friction pawls for preventing retrograde
movement of the pulley are pivoted by their inner ends on the loom frame or some
part attached thereto, and each pawl, from its pivoted point, extends outwardly
towards the inner periphery of the pulley rim in a line which is more or less at
an angle to a line truly radial from the centre of said pulley and passed through said
pivotal point. Each of the springs consists of a length of spring wire, bent by a
portion thereof near one end into one or more convolutions to encircle a fixed stud,
the end of the wire adjacent thereto being secured to the side of the loom frame or
some part affixed thereto, and the other end portion of the wire constitutes a spring
arm to bear on the edge of the pawl, and is formed with an angular end. The edge of
the pawl is provided with a channel in which the angular end of the spring arm lies.
Beyond the angular extension of the spring arm, a hole is formed in the pawl, and
should it be desirable to hold the clutch pawl out of operative engagement with
the pulley, as for instance at the time of setting up or repairing the take-up
mechanism, by swinging the pawl rearwardly against its spring, allowing the
angular extremity of the latter to enter the hole in the pawl, owing to the fact that the
spring arm and pawl swing from different centres, the pawl and spring will interlock
and so remain, the end of the pawl being held out of contact with the internal
periphery of the pulley.
Various forms of driver levers for the pulley may be provided, which are capable,
when swung in one direction, of also securing a small extent of partial rotation of the
pulley, but which, when swung backward, have no effect to rotate said pulley.

Improvements in Take-up Mechanism for Looms.
A communication from abroad by AMAZIAH SANDERSON WARNER, of 24, Sumner
Avenue, Machinist, ALLEN LEVI SKINNER, of 41, Osgood Street, Pattern Maker,
and GEORGE CLIFTON WILSON, of 30, King Street Avenue, Grocer, all of

1. WILLIAM PHILLIPS THOMPSON, F.C.S., M.L.M.E. of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both
in the County of Lancaster, and 23, High Holborn in the County of Middlesex,
Civil Engineer, 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 :-
This invention relates to improvements in take-up mechanism for looms, the object
thereof being to provide a mechanism adjustable as to the parts thereof and inter-
vening between the lay-frame and the take-up roll or cloth-beam, whereby, in the
running of the loom for the making of any desired grade of cloth, the take-up roll,
through the said adjustable connections, will have a rotation and peripheral movement
exactly corresponding to the production of cloth by the loom; and the invention
consists in the construction and combination of parts all substantially as will hereinafter
more fully appear and be set forth in the claims.
Reference is to be had to the accompanying drawings forming part of this
specification, in which,
Figure 1 is an elevation of a portion of the end of a loom having applied thereto
take-up mechanism for rotating the cloth-beam intermittently, embodying the
improvements.
Figure 2 is an elevation of a portion of the front of the loom, being of the
same parts shown in Figure 1, but at right angles thereto.
Figure 3 is a view illustrating a clutch employed in the present take-up
mechanism as in its working relation to, and on the rim of, a pulley also comprised
in said mechanism, which pulley rim and parts of the driver therefor are shown in
section on the plane indicated by the line 33, Figure 2.
Figures 4, 5, and 6. are views on an enlarged scale of detail parts of said clutch
mechanism to be hereinafter particularly referred to.
Figure 7 is an enlarged central vertical section of an arm to be connected to and
movable with the lay-frame and showing the adjusting means carried thereby for the
connection of the link hereinafter referred to.
Figure 8 is a longitudinal sectional view of the link between the arm last mentioned
and parts of the swinging driver for the take-up.
Figure 9 is a view illustrative of a modification of construction to be hereinafter
referred to.
Figure 10 is a detail view of the hub of the driver hereinafter referred to.
In the drawings, A represents a portion of the end frame of a loom, and B the
lay-frame, which, by the bottom of the lever-aruns 6 thereof, is pivotally mounted on
a horizontal shaft d having suitable bearings in the frame of the machine, said shaft
projecting beyond the end of the frame, and receiving thereon the upwardly
projecting rigid radial arm C.
a represents the shaft for the cloth-beam or take-up roll mounted in bearings e in
the frame of the machine. For wide goods the take-up consists of a long roll fixed
on or adapted to be connected as one with said shaft a, while for narrow goods, as
tape or ribbon, several rolls, as c, are mounted on the take-up shaft at suitable
intervals in the length of the loom. With said take-up rolls the fabric produced
by the loom is to have a frictional contact, said fabric being held in such contact by
any suitable means, as by additional pressure and guide rolls, and all as usual or
desirable under ordinary and well known constructions.

page_text: 9 represents a short shaft or stud rotatable in suitable bearings in the frame A
and projecting both inwardly and outwardly a short distance therefrom, and on said
shaft is a pinion g', with which meshes a gear h of large diameter that is fixed on
the take-up shaft a. Outside of the frame on said shaft g is fixed a pulley D, and
also on said shaft outside of the said pulley is mounted, by an intermediate portion
and to loosely swing thereon, a driver-lever E having at the end of its upper arm
an angular projection i to fit and bear upon the outer periphery of the rim of the
pulley, and said driver is adapted, by mechanism to be hereinafter set forth, when
swung in one direction to bind on the outer periphery of said pulley to turn it,
and on being swung in the opposite direction to move over the periphery without
effect to turn the pulley. On the end of the lower arm of the driver which is
extended somewhat below the rim of the pulley is an angular projection ; provided
on its inner side with an ear-piece j¹; and a pivot-bolt k passes through and is
supported in the lower end portion of the driver and said ear-piece on which is
pivoted a dog F, provided at one side of its pivotal point with a nose for engage-
ment, when properly swung, with the outer periphery of the pulley, said dog at
the other side of its pivotal point being rearwardly and then downwardly extended
in an angular arm m. The bore or opening of the hub of the driver-lever is
slightly elongated in the direction of the length of the said lever, as
Figure 10.
seen in
Between the radial lever-arm C, fixed on the shaft d for the lay-frame, and the
downward extension of the dog F is a link H adapted to be adjustably secured to
one or both of said parts. As particularly shown in Figures 1, 8 and 9, such
connections are made as follows:-
The said arm C has a longitudinal slot n therein extending from near its hub
to within a short distance of its outer end, where it is formed with a cross web o
of hub form having a central bore o' in the direction of the length of said slot.
A block p fits to slide in said slot, having at its one end a head q, and at its
other it is necked down and outwardly extended in a spindle r of reduced diameter.
It will be noticed that the central or block portion p of the part just described is
of slightly less length than the width of the slot walls, (see Figure 8). A sleeve s
having at its inner end an outwardly extending flange s¹ lies loosely over said
spindler, and over said sleeve fits the bore of the hub u at one end of the said
link. and is held in place by the nut t. A similar form of connection is shown as
employed for uniting the other end of said link with the slotted arm of the dog F.
By tightening the nut, the sleeve flange is forced against one side of the lever or dog
arm, and the head q of the said block is drawn against the other side of said lever
or arm. On loosening the nut, the block is free to be moved up or down in its
guiding slot, and a practical and efficient means for so moving said block and
securing a minute adjustment thereof for regulating the throw of the driver, and
resultant amount of take-up will be seen on reference to the sectional view of the
arm C, Figure 7, wherein the said block p is shown as provided with a vertical
screw-theaded opening v, with which engage the threads of a vertical screw-rod w,
having a shoulder as at which lies beneath the hub web o of the arm, said rod
being upwardly projected through and beyond the bore of said hub web and
receiving a head having a knurled rim, said head being keyed on said rod and
employed for conveniently turning the rod.
In order that the link connection between the arm C and dog arm m may act
evenly and without any tendency to lateral or torsional draught on either of said
parts whereby they would be forced out of a vertical plane for their most efficient
operation, a duplicate link H¹ is provided, as seen in Figure 8, by its hub bore
loosely fitting over the circular and somewhat reduced portion y of the head of each
block p. The said duplicate link H₁ is held against its fellow and in its bearing
on the eircular heads of the said blocks by the bolt passed through an inter-
mediate part of each of said link members and retained to its confining action by
a nut
Fixed on the frame of the loom just within the pulley D is a clutch mechanism J,

page_text: consisting of one or more pawls 20 pivoted by their inner ends on the loom frame,
or, what is the same in substance, on a disc 22 bolted thereto. Each pawl from
its pivotal point 23 extends outwardly towards the inner periphery of the pulley rim
in a line which is more or less at an angle to a line truly radial from the centre of
the said pulley and passed through said pivotal point, said pawl being held to a
bearing by its end in the said periphery by a spring 24, suitably applied.
An approved construction of the spring-pawl-device will be particularly seen on
reference to Figures 4, 5 and 6. The spring consists of a length of spring wire, by
a portion thereof near one end formed into one or more convolutions to encircle a
fixed stud 25, and said end adjacent thereto being secured to the disc, the other
end portion of said wire constituting a spring-arm, 26, to bear on the edge of the
pawl and formed with an angular end 27. The edge of the pawl is provided with
two parallel ribs 28, with an intermediate channel 29 between them and in which
said spring-arm lies and is held to operative position on the pawl. Beyond the end
of the angular extremity of the spring-arm is an aperture 30 in the pawl, and
should it be desired to hold the clutch pawl out of operative engagement with the
pulley, as for instance, at the time of setting up the take-up mechanism, by forcing
the pawl rearwardly against its spring, allowing the angular point of the latter to
enter the said aperture, as indicated in dotted lines in Figure 4, owing to the fact
that the spring-arm and pawl swing from different centres, the pawl and spring will
interlock and so remain that the end of the pawl will be out of contact with the
rim of the pulley. The stud 25 is formed with a head 32 to prevent the spring
coils from being detached from its shank (see Figure 6).
In operation, on the forward spring of the lay-frame, the arm C also swings
therewith, and a forward thrust of the link H will result, having a greater or less
extent according as the connection thereof with said arm C is further from or nearer
to the centre of oscillation thereof. As the link moves forward, the vertical arm of
the dog is thereby swung forward, the nose of said dog at the other side of the pivotal
point immediately swinging upwardly and rearwardly against the outer periphery of
the pulley, and, working between its pivotal point and the said rim, exerts a prying
action on the driver to draw it slightly downwardly, its elongated hub bore 50
passing over the shaft 9, and bringing its angular extension i into a firm bearing on
the upper portion of the pulley's periphery for turning the pulley a slight distance.
The clutch pawl or pawls are so applied that such positive feed motion of the pulley
is in no way interfered with; but as the lay-frame assumes its reverse movement,
and the dog-lever swings rearwardly and its nose downwardly, the driver lever is
permitted to recede over the rim of the pulley for a new grip, and any liability of
backward movement of the said pulley resulting from friction on the retracing of the
movable parts thereon will be positively prevented by the pawls.
In order that there may be no lash or freedom of movement between the nose of
the dog and the rim of the pulley, as the parts retrace, whereby a lost motion might
be had on the forward movement of the arm C, before the take-up mechanism is
caused to operate, a spring 40 is applied between the end of the driver and the
vertical arm of the dog, to cause the latter to be so swung that its nose will always
be in contact on the pulley-rim.
It will be plain that, on loosening the nut t, and turning the head of the screw-
rod w, the end of the link may be nicely adjusted on the arm C so as to have any
length of throw desired, and that the take-up roll will, from any given step of the
pulley, be given a proportionate movement to take up the fabric, and under the
adjustable devices substantially as described, the take-up may be readily and accurately
set to move to any desired extent according to the grade of cloth which it is desired
to produce in the loom.
In Figure 9, a shoe L, of extended bearing area, is shown as interposed between
the nose of the dog F and the rim of the pulley, by the provision of which the
surface of said rim will not become serrated or indented, and, furthermore, various
forms of driver-levers for the pulley may be provided, which are capable, when

page_text: swung in one direction, of also securing a small. extent of partial rotation of the
pulley, but which, when swung backward, have no effect to rotate said pulley.
