Improvements in and connected with Warping Mills.
I, WILLIAM WHITELEY, of the Firm of William Whiteley and Sons, Limited
of Prospect Iron Works, Lockwood, near Huddersfield, Yorkshire, Machine
Makers, do hereby declare the nature of this invention to be as follows:-
This invention has reference to what are known as horizontal or Scotch warping
mills and relates to the method of and means for adjusting the angles or inclined
planes employed for the building up of the sections of warp on the mill so as to
adapt said machine for various widths of warp, each of which can therefore be
built up against the said angle piece or inclined planes whether wide or narrow,
and also to the combining with said warping mill of a stop motion for stopping
same on the breakage or severance of an end or ends of warp.
In carrying out my invention the angular pieces or inclined planes are made
separate from the horizontal bars onto which the warp is wound, and are arranged
alongside same and secured to two flanges or rims connected to a disc mounted
loosely on the shaft of the warping mill and adapted to slide laterally thereon.
Preferably two or more screws are employed working through nuts in the said
disc and passing through a fixed disc on the same shaft, which said screw on being
rotated by means of a key, handle, or wheel causes the first named disc with its
double flanges or rims and inclined planes to travel laterally either towards or from
the centre of the warping mill to any distance required to adjust them to the width
of warp to be wound upon the mill. In order to equally actuate the screws we
provide each with a pinion and gear them together by means of a carrier wheel so
that by rotating one of said screws the other screw or screws are likewise
rotated to the same extent and more easily and expeditiously than if actuated
separately.
We also combine with the horizontal or Scotch warping mill apparatus for
automatically stopping the same on the breakage or severance of an end or ends of
warp between the bobbin creel and warping mill.
The said apparatus is attached to the carriage of the bobbin creel so as to
travel therewith and consists of suitable pins or bent wires suspended on the ends
of warp at a convenient distance from the creel, the said pins or bent wires entering
corresponding openings in a grate or between longitudinal bars acting as guide
plates. When an end is absent from any cause the pin or wire which was suspended
thereby falls down between the nipping rollers, one of which is moveable laterally
in its bearings and is consequently forced apart from the other roller by the said
pin. In its lateral movement the roller releases a spring or catch which by means
of suitable rods and levers actuates the strap fork of the warping mill and transfers
the strap from the fast to the loose pulley thereby bringing the machine to a
standstill. The tension of the warp threads is maintained by means of a roller
resting on said threads and adapted to rise and fall in slotted bearings according as
the warp slackens or tightens.
A compensating lever carrying at its free end a roller round which the warp
threads are caused to pass is also employed for the purpose of compensating for
any difference in the delivery and taking up of the warp by the bobbin creel and
warping mill respectively, and by suitable connections is adapted to actuate a cam
which on its shorter radii being brought to act on a lever oscillates same in such
manner as to throw the friction driving discs of the warping mill temporarily out
of contact and reduce the speed of the warping mill in conformity with the
decreased speed of delivery, but on the acceleration of delivery of the warp, the

page_text: longer radii of the cam forces the friction disc again into frictional contact and
the warping mill regains its normal speed.

Improvements in and connected with Warping Mills.
I WILLIAM WHITELEY, of the Firm of William Whiteley and Sons, Limited,.
of Prospect Iron Works, Lockwood, near Huddersfield, Yorkshire, Machine
Makers, 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 has reference to what are known as horizontal or Scotch warping
mills and relates to the method of and means for adjusting the angles or inclined
planes employed for the building up of the sections of warp on the mill so as to
adapt said machine for various widths of warps, each of which whether wide or
narrow can therefore be built up against the said angle pieces or inclined planes,.
and also to the combining with said warping mill of a stop motion for stopping
same on the breakage or severance of an end or ends of warp.
For the purpose of more fully describing my invention reference is hereinafter
had to the annexed drawings, wherein Fig. 1 is side elevation of a horizontal or
Scotch warping mill with my improvements applied and having a stop motion
combined therewith, the latter being shewn in section, and Fig. 2 is sectional
plan view on an enlarged scale of the warping mill.
In the drawings A represents the warping mill constructed of longitudinal bars
or laths B secured to rims or hoops D carried by arms E bolted to central discs
or plates F fast on the shaft G which receives motion through the medium of
gearing H and friction driving discs H' from the main driving shaft I, said parts
being arranged and operated for the purpose of winding the warp onto the bars B,
in the same manner as heretofore.
Mounted loosely on the shaft Gand adapted to slide laterally thereon is a disc
or plate J to which are bolted radial arms K carrying two rims or hoops L to
which are secured angular pieces or inclined planes M arranged alongside the
bars B at one end of the warping mill and employed to build up the sections of
warp to the required angle as is understood. In order to adjust the said inclined
planes so as to adapt the machine for winding various widths of warps, I secure in
the near disc F two or more screws N of suitable length which work through
nuts in the loose dise J, and, when rotated, cause the said disc together with the
rims L and inclined planes M to move laterally in the direction of the arrow and
as indicated in dotted lines in Fig. 2 and also in the reverse direction, whereby
the capacity of the warping mill is reduced or increased to the maximum according
to the width of warp to be wound thereon. The screws N are provided with square
ends projecting through openings in the toothed wheel H on shaft G, on which a
suitable key can be placed to actuate the screws. For the purpose of giving equal
movement to the screws N I provide each with a pinion N which gear with a
carrier wheel N² mounted on the shaft G so that when one of said screws is rotated
the other screw or screws is or are likewise rotated to the same extent and more
easily and expeditiously than if actuated separately. The disc J and parts
connected therewith are made to revolve with the shait G by means of connecting
rods which are secured to the discs F and pass through and engage with slots in
the said disc J.
My invention further relates to combining with said warping mill means whereby

page_text: the same shall be automatically stopped on the breakage or severance of an end or
ends of warp intermediate of the bobbin creel and warping mill.
Referring to Fig. 1 P represents the bobbin creel to which is attached so as to
travel therewith the framework Q carrying the parts forming the stop motion and
the several rollers R over and under which the warp a traverses on its way from
the bobbin creel to the warping mill. The warp is drawn off the bobbins by the
nipping rollers R' which receive motion from diagonal shaft R2 driven by bevil
wheels R³ from the driving shaft I, said shaft R2 also imparting motion through.
gearing R to a second pair of nipping rollers S, S', the latter of which is carried
on one end of a lever Spivoted to the frame at S. Above the rollers S, S¹, is
a grate or series of longitudinal guide plates T through or between which pass
bent pins or wires T' suspended on the warp. So long as the ends of warp remain
intact, the bent wires are supported thereby clear of the nipping rollers S, S¹, but
should an end break or be absent from any cause, the bent wire which was
suspended thereon, having lost its support, falls down between the said nipping
rollers and forces roller S away from roller S thereby moving the lever S² on its
pivot in the direction of the arrow and causing an incline S' on the lower
end thereof to bear against the edge of a spring U and force it clear of a.
catch U.
The kinetic energy of the spring when thus liberated forces backward a rod V
connected to a lever on a cross shaft such as V and oscillates said shaft which by
means of a second lever V actuates the strap guide V3 and shifts the strap from
the fast to the loose pulley on the shaft I whereby the combined warping mill and
beaming machine are stopped. The tension of the warp threads is maintained by
means of a roller W resting on said threads and adapted to rise and fall in the
slot Waccording as the warp tightens or slackens.
A compensating lever X carrying at its free end a roller X' under which the
warp is caused to travel is also employed for the purpose of compensating for any
difference of speed in the delivery and taking up of the warp by the bobbin creel
and warping mill respectively. The said lever X is connected by rod or link X
to a lever secured on a shaft X on which is mounted a cam X' engaging with
a lever pivoted at Y' and secured at its opposite end to the lower friction driving
dise H which is forced into or lowered out of contact with the upper friction
driving disc according as the longer or shorter radii of the cam X are brought to
act on the lever Y. The movement of the cam is determined by the lowering or
raising of the lever X owing to the speed of the delivery of the warp being in
excess of or below that of the winding on of the warp which respectively cause
the shorter or longer radii of the cam to be brought to bear on the lever Y and to.
throw the friction driving discs out of or into contact with each other and thereby
reduce or accelerate the speed of the warping mill in conformity with the
accelerated or reduced speed at which the warp is delivered.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is
Firstly. In horizontal or Scotch warping mills, a disc or plate J adapted to be
slided laterally on the warping mill shaft, together with rims or hooks carried by
said disc and having angle pieces or inclined planes secured thereon all arranged
and operating in the manner and for the purposes substantially as herein shewn
and described.
Secondly. In warping mills the combination, with a disc such as Jaud parts.
connected therewith, of screws N pinions N' and carrier wheel N² operating in the
manner and for the purposes substantially as herein shewn and described.
Thirdly. In a warping mill the combination, with disc J and rims or hoops L
connected thereto, of the inclined planes or angle pieces and means for adjusting
same to suit different widths of warp substantially as shewn and described.
Fourthly. The combination, with a horizontal or Scotch warping mill, of the

page_text: means for automatically stopping the same on the breakage or failure of an end or
ends of warp substantially as herein shewn and described.
Fifthly. The combination, with a horizontal or Scotch warping mill and automatic
stop motion of means for maintaining the tension of the warp and compensating for
any difference in speed between the delivery and winding on of the warp
substantially as herein shewn and described.
