Improvements in Certain Machinery or Apparatus for Winding
Yarns or Threads.
I, HERBERT BALFE of Platt Holme, Levenshulme, in the County of Lancaster,
Manager, do hereby declare the nature of this invention to be as follows:-
My invention relates to the machinery or apparatus for winding yarns or threads
in which each of the two or more yarns or threads being wound upon a tube or
spool or bobbin is caused to pass through and be guided or traversed to and from
laterally by means of an oblique or waved slit formed in a revolving drum against
which the said tube, spool or bobbin or the yarn or thread wound thereon is caused
to bear and in which the revolving drums are mounted in fratnes arranged so as to
be capable of being moved when required so that the bands employed to transmit
rotary motion to the said drums may be made tight so that motion shall be imparted
to the said drums or slackened so that they may cease to impart motion to the
drums with which they are respectively employed and in which there are provided
stop-motions or arrangements of apparatus for allowing or causing the frame in
which a revolving drum is mounted to move so as to slacken the band employed
with such drum should one or more of the yarns or threads being wound upon a
tube, spool or bobbin by means of such drum break or terminate. My invention
consists in improvements the object of which is to cause the revolving drums
employed in machinery of the said kind to be stopped more quickly than they have
been by the means hitherto employed, when moved so that the bands by which
such drums receive motion are slackened in order that broken yarns or threads
may be pieced or for other purposes.
According to my invention I provide in conjunction with each drum employed
in a machine of the kind to which my invention relates, a brake or wedge which
is connected by means of a hinged or other joint of any suitable kind or rigidly
secured to a part or rod formed or provided or supported in a suitable position, in
the machine. The said brake or wedge is mounted in such position in the machine
in which it is employed that as the drum in conjunction with which it is employed
is moved in order that the band employed to impart motion to it may be slackened
the drum upon which the said brake or wedge is intended to act shall pass into
contact with one surface of such brake or wedge while a bar or rod either forming part
of the arm or cradle in which the said drum is mounted or provided in or on the
said arm or cradle to act in conjunction with the said brake or wedge shall pass
into contact with the other surface of the said brake or wedge and any continued
movement of the said drum in the direction for slackening the said band shall
press the said drum and bar or rod more forcibly on to the said brake or wedge.
The said brake or wedge will thus cause the said drum to be quickly stopped when
moved in order that the band employed to impart motion to such drum may be
slackened. The said brake or wedge is preferably covered with leather or any
other suitable covering in order that it may more readily stop the drum in
conjunction with which it is employed without tending to roughen or otherwise
injure it. My invention is applicable to machines of the kind above mentioned
whether the drums employed therein are arranged to be supported and driven
individually or in pairs or groups and the several brakes or wedges made according

page_text: to my invention which may be required in a machine of the said kind may be
constructed and applied independently of each other or they may be constructed in
groups or formed or connected together in any suitable manner."

Improvements in Certain Machinery or Apparatus for Winding
Yarns or Threads.
1, HERBERT BALFE, of Platt Holme, Levenshuline, in the County of Lancaster
Manager, 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 invention relates to the machinery or apparatas for winding yarns or threads
in which each of the two or more yarns or threads being wound upon a tube or
spool or bobbin is caused to pass through and be guided or traversed to and fro
laterally by means of an oblique or waved slit formed in a revolving drum against
which the said tube, spool or bobbin or the yarn or thread wound thereon is caused
to bear and in which the revolving drums are mounted in frames arranged so as to
be capable of being moved when required so that the bands employed to transmit
rotary motion to the said drums may be made tight so that motion shall be
imparted to the said drums or slackened so that they may cease to impart motion
to the drums with which they are respectively employed, and in which there are
provided stop motions or arrangements of apparatus for allowing or causing the
frame in which a revolving drum is mounted to move so as to slacken the band
employed with such drum, should one or more of the yarns or threads being wound
upon a tube, spool or hobbin by means of such drumm, break or terminate. My
invention consists in improvements the object of which is to cause the revolving
drums employed in machinery of the said kind to be stopped more quickly than
they have been by the means hitherto employed, when moved so that the bands by
which such drums receive motion are slackened in order that broken yarns or
threads may be pieced or for other purposes.
According to my invention I provide in conjunction with cach drum employed
in a machine of the kind to which my invention relates, a brake or wedge which is
connected by means of a hinged or other joint of any suitable kind or rigidly
secured to a part or rod formed or provided or supported in a suitable position in
the machine. The said brake or wedge is mounted in such position in the machine
in which it is employed, that as the drum in conjunction with which it is employed
is moved in order that the band employed to impart motion to it may be slackened,
the drum upon which tho said brake or wedge is intended to act shall pass into
contact with one surface of such brake or wedge while a bar or rod either forming
part of the arm or cradle in which the said drum is mounted or provided in or on
the said arm or cradle to act in conjunction with the said brake or wedge shall pass
into contact with the other surface of the said brake or wedge and any continued
movement of the said drum in the direction for slackening the said band shall press
the said drum and bar or rod more forcibly on to the said brake or wedge. The
Enid brake or wedge will thus cause the said drum to be quickly stopped when
moved in order that the band employed to impart motion to such drum may be
slackened. The said brake or wedge is preferably covered with leather or any
her suitable covering in order that it may more readily stop the drum in
conjunction with which it is employed without tending to roughen or otherwise

page_text: injure it. My invention is applicable to machines of the kind above mentioned
whether the drums employed therein are arranged to be supported and driven
individually or in pairs or groups and the several brakes or wedges made accor ling
to my invention which may be required in a machine of the said kind may be
constructed and applied independently of each other or they may be constructed
in groups or formed or connected together in any suitable manner.
In order that this invention may be more readily carried into effect, I will now
proceed to further describe it with reference to the accompanying drawing, in
which as machines of the kind to which my invention relates are well known,
I have only shown such parts as are requisite for the illustration of my invention
and the manner of carrying it into effect.
In the said drawing,
Fig. 1 is a side elevation, and Fig. 2 is a front elevation showing one of the
revolving drums employed in machinery or apparatus of the kind to which my
invention relates, and some of the parts by means of which such drum is supported,
and a brake or wedge provided in accordance with my invention, and
Fig. 3 is a plan of the said brake or wedge drawn apart from the other parts
shown in Figs. 1 and 2.
The projecting ends of the axle (a) of the drum (a) illustrated in Figs. 1 and 2
are arranged to revolve in notches formed in a frame or cradle (4) formed of arms
which are connected by means of a cross-bar or rod (6') cast, therewith, and are
capable of being oscillated on pins or axles (c') secured in brackets (c) mounted
upon a rail (d) extending lengthwise of the machine. The band (e) employed to
impart motion to the drum (a) by means of the pulley (a 2) formed thereon is
tightened to impart motion to the said drum (a) or slackened so as to cense to
impart motion to such drum by means of any apparatus suitable for the purpose,
such as is ordinarily employed in machinery or apparatus of the kind to which my
invention relates. The means for tightening and slackening the band (e); the
means for supporting the tube, bobbin or spool on which yarn or thread is to be
wound by means of the drum (a); and the stop motion employed to cause the
drum (a) to move and slacken the band (e) when one of the yarns or threads being
wound breaks or terminates are omitted from the accompanying drawing as they
form no part of my invention, and may be similar to the arrangements heretofore
used for such purposes in machinery or apparatus of the kind to which my
invention relates. The brake or wedge (f) which is illustrated in Figs. 1, 2
and 3 is formed of a piece of flexible sheet metal (f) formed with a slot through
which are passed set screws serving to secure such piece of sheet metal (¹) to an
arm (2) formed with a collar (3) which embraces a rod (9) and is secured in
position upon such rod (9) by means of a set screw (9'). The rod (g) extends
lengthwise of and is secured in position in any suitable manner in the machine in
which the drum (a) is employed. Upon the piece of sheet metal (1) there is
secured a piece of leather or other suitable material (4) which will render the
brake more efficient in stopping the drum (a) without tending to roughen or
otherwise injure it. The brake or wedge (f) is mounted in such position, that us
soon as the said drum (a) is allowed or caused to move in the direction indicated
by the arrow (A), from the position occupied by such drum when revolving in
order to wind yarn or thread, and the band (e) is slackened so that it may cease
to impart rotary motion to the drum (a), the said drum (a) shall pass on to the
part of the brake or wedge (f) which is covered with leather or other material
and the arm (1) of the frame or cradle (6) shall pass beneath the said part of the
brake or wedge (f) so that the continued movement of the drum (a) in the
direction indicated by the arrow (A) will press the arm (6) upon the said brake
and so cause the said brake to bear more forcibly against the drum so as to exert
a greater retarding effect thereon. The said drum is thus caused to be quickly
stopped, whenever it is moved or allowed to move in the direction indicated
by the arrow (A) from the position which it occupies when winding yarn or
thread.

page_text: It is obvious that instead of being secured in position upon the rod () in the
manner illustrated in Figs. 1 and 2, the brake or wedge () may be mounted upon
a binge or pivotted to such rod in any suitable manner, so long as it is prevented
from descending too low for the bar () of the frame or cradle (b) to pass beneath
it when the drum (a) is allowed or enused to move in the direction indicated by
the arrow (A).
Brakes provided according to my invention are simple in construction and not
liable to derangement and cuable the drums in conjunction with which they are
employed to be stopped more quickly than has been possible with the ineans
hitherto provided in inachinery or apparatus of the kind to which my invention
relates, and so enable the finding and piecing of broken yarus or threads to be
effected more easily and quickly than has hitherto been the case in machinery or
apparatus of the said kind.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The combination with each of the revolving drums employed in machinery or
apparatus of the kind herein before described of a brake or wedge arranged and
mounted substantially in the innumer and for the purpose hereinbefore described
Fo that the drum in conjunction with which such brake or wedge is employed will
as it is moved in order that the band employed to impart motion to it may be
slackened pass into contact with one surface of such brake or wedge, while a bar
or rod forming part of or mounted or provided in the frame or cradle in which the
said drum is mounted shall pass into contact with the other surface of the said
brake or wedge and any continued movement of the said drum in the direction for
slackening the said band shall press the said drum and bar or rod more forcibly
upon the said brake or wedge.
