Improvements in or connected with Sectional Warping Machines.
I, HERBERT CALVERT, of Albany Mills, Firth Street, Huddersfield, Yorkshire,
Worsted Spinner, do hereby declare the nature of this invention to be as follows:-
This invention relates to sectional warping machines and my improvements
consist, firstly, in combining with the swift, on which the warp is built up in
sections side by side, a bobbin creel, a stop motion, and a
heck"
mounted reed, all secured on a platform or carriage provided with wheels adapted
or horizontally
to run on rails laid on the floor, and which is moveable longitudinally of the
swift either automatically or by hand in the same ratio and corresponding to the
progressive lateral movement of the section builder; secondly, in providing means
coupled with the stop motion for stopping the rotation of the swift immediately
on the breakage of an end or ends of warp at whatever position the travelling
carriage may have been moved to; and, thirdly, in the method of and means for
adjusting the height of the "heck" or reed.

In carrying out my invention I employ a bobbin creel preferably constructed
V shape, especially if a large number of ends are being dealt with; but other
constructions of creel may be employed, if desired. The V shaped creel delivers
the ends from the centre or base outwards on each side to the full capacity of the
creel in a free and open order so that there is no liability of them becoming mixed
or entangled and they are brought side by side to the stop motion, which is of any
suitable construction applicable to sectional warping mills, and from the stop
motion they are threaded through the "heck' or reed in the ordinary way, but
instead of said "heck or reed being arranged vertically as is usually the case, it
is placed horizontally in front of the stop motion and mounted on telescopic
pillars which can be raised and lowered in tubular pedestals by racks and pinions
or like means and adjusted to any desired height. The aforesaid parts, comprising
three separate apparatuses, are secured on a large carriage or platform mounted
on wheels which said platform is moveable, by hand or automatically, in a
direction longitudinally of the swift, the means employed to traverse said carriage
being either a hand wheel and pinion, the latter gearing with a rack, or a shaft
driven from a part of the mechanism giving motion to the swift and on which are
mounted pinions gearing with racks secured to the carriage so that said carriage
will be moved from end to end of the swift progressively in the same way and
coincident with the progressive movement of the section builder, whereby the
creel stop motion and reed are always lineable with the section of warp being
wound on the swift. It will be obvious that instead of the creel, stop motion and
reed being on one platform or carriage, they may be secured on separate platforms
or carriages which, however, would be traversed by the same means as the single
carriage.
In order to stop the rotation of the swift on an end of warp breaking or failing I
couple to the stop motion a rod or tube over or into which fits telescopically
rod ог bar connected by suitable intermediate mechanism with the
B

page_text: knock off rod or strap guide of the swift. The said rod or bar
is made square or angular or provided with flats adapted to engage with the corre
sponding square or flat sides of the tube or rod in or on which it fits and thus,
while the latter is free to move endwise with the carriage to the full limit in
either direction, any rocking or rotary movement imparted to it by the actuation
of the stop motion on the failure of an end of warp, is communicated to the rod
or bar which, through the medium of the intermediate connections, operates the
means for stopping the swift which is thus immediately brought to a standstill no
matter to what extent the carriage has been traversed towards the opposite end
of the swift. For the purpose of driving the stop motion as it travels from end to
end of the swift, employ an overhead pulley, or barrel, or drum, of a length
equivalent to the distance the stop motion travels so that the driving strap can
move over same laterally with the movement of the stop motion.
By combining a crcel stop motion and "heck" or reed on a moveable base, with
a swift for sectional warping in the manner set forth, a warp containing a large
number of ends can be wound in sections on the swift as easily and expeditiously
as a small number of ends, and the attendant is relieved of the duty of watching
for broken ends and of stopping the machine when any are discovered; there is
no liability of a section being wound on with a broken end in same, and no
necessity for unwinding a few laps or warp and disturbing the structure of the
section in order to find a broken end an evil which hitherto has had to be contended
with the this class of machine.
From the swift the warp can be wound direct on to the beam which is mounted
in bearings at the rear of the swift and the use of bobbins or the like now employed
intermediate of the swift and beam are dispensed with.
The method and means for adjusting the height of the "heck' or reed gives
easy access to and control over same.

Improvements in or connected with Sectional Warping Machines..
I, HERBERT CALVERT, of Albany Mills, Firth Street, Huddersfield, Yorkshire,
Worsted Spinner, 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 sectional warping machines, and my improvements
consist, firstly, in combining with the swift, on which the warp is built up in
sections side by side,-a bobbin creel, a stop motion, and a "heck or horizontally
mounted reed, all secured on a platform or carriage provided with wheels adapted
to run on rails laid on the floor, and which is movable longitudinally of the
swift either automatically or by hand in the same ratio and corresponding to the
progressive lateral movement of the section builder; secondly, in providing means
coupled with the stop motion for stopping the rotation of the swift immediately
on the breakage of an end or ends of warp at whatever position the travelling
carriage may have been moved to; and, thirdly, in the method of and means for
adjusting the height of the "heck" or reed.
In carrying out my invention I employ a bobbin creel preferably constructe l'
V shape, especially if a large number of ends are being dealt with; but other
constructions of creel may be employed, if desired. The V shaped creel delivers
the ends from the centre or base outwards on each side to the full capacity of the

page_text: 32
creel in a free and open order so that there is no liability of them becoming mixed
or entangled and they are brought side by side to the stop motion, which is of any
suitable construction applicable to sectional warping mills, and from the stop
motion they are threaded through the "heck" or reed in the ordinary way, but
instead of said "heck or reed being arranged vertically as is usually the case, it
is placed horizontally in front of the stop motion and mounted on telescopic
pillars which can be raised and lowered in tubular pedestals by racks and pinions
or like means and adjusted to any desired height. The aforesaid parts, comprising
three separate apparatuses, are secured on a large carriage or platform mounted
on wheels which said platform is movable, by hand or automatically, in a
direction longitudinally of the swift, the means employed to traverse said carriage
being either a hand wheel and pinion, the latter gearing with a rack, or a shaft
driven from a part of the mechanism giving motion to the swift and on which are
mounted pinions gearing with racks secured to the carriage so that said carriage
will be moved from end to end of the swift progressively in the same way and
coincident with the progressive movement of the section builder, whereby the
creel stop motion and reed are always lineable with the section of warp being
wound on the swift. In order to stop the rotation of the swift on an end of warp
breaking or failing I couple to the stop motion a rod or tube over or into which
fits telescopically a rod or bar connected by suitable intermediate mechanism with
the knock-off rod or strap guide of the swift. The said rod or bar is made square
or angular or provided with flats adapted to engage with the corresponding square
or flat sides of the tube or rod in or on which it fits and thus, while the latter is free
to move endwise with the carriage to the full limit in either direction, any rocking
or rotary movement imparted to it by the actuation of the stop motion on the
failure of an end of warp, is cominunicated to the rod or bar which, through the
medium of the intermediate connections, operates the means for stopping the swift
which is thus immediately brought to a standstill no matter to what extent the
carriage has been traversed towards the opposite end of the swift. For the purpose
of driving the stop motion as it travels from end to end of the swift, I employ an
overhead pulley, or barrel, or drum of a length equivalent to the distance the stop
motion travels so that the driving strap can move over same laterally with the
movement of the stop motion.
In order that my said invention may be fully described and ascertained, reference
is hereafter had to the annexed sheets of drawings forming a part of this
Specification, in which:-
-
Fig. 1 is elevation shewing my improvements as applied to and combined with a
Scotch warping mill.
Fig. 2 is longitudinal elevation, looking in the direction of arrow 1 in Fig. 1,
of the stop motion and parts connected therewith for stopping the rotation of the
swift or warping mill when an end of warp breaks or fails.
Fig. 3 is side elevation of my improved adjustable "heck" or reed, and end'
lease.
Fig. 4 is plan of part of same.
Referring firstly to Fig. 1, letter A represents the bobbin creel in which the
bobbins of warp to be wound on the warping mill are mounted, B the stop motion,
C the adjustable heck or reed D the section builder and E the warping mill or
swift. The first part of my invention consists in combining with the warping
mill E, a bobbin crcel, A, stop motion B and adjustable heck or reed C all mounted
on one platform or cariage F, provided with wheels G adapted to run on rails or
lines H laid on the floor, and which is moveable laterally or longitudinally of the
warping mill E either automatically or by hand in accord with or corresponding to
the progressive lateral movement of the section builder. The means shewn for
traversing the carriage or platform F longitudinally across the width of the
warping mill are for operation by hand and comprise a hand wheel I mounted on
a vertical shaft I supported in a footstep or bearing in the bracket J secured to
the platform F, on the lower end of said shaft being secured a skew gear or worm I2*

page_text: gearing into a skew gear wheel K mounted on a stud or short shaft carried by the
aforesaid bracket J and whereon is also mounted a pinion K¹. The pinion K¹ gears
with a rack K2 secured to the floor, and when rotated by the turning of the hand
wheel I it is caused to travel over said rack whereby the platform F is moved
bodily any distance required at will. The platform or carriage may, however, be
traversed automatically from side to side of the warping mill progressively with
the section builder, this being effected by a screw or worm and gearing deriving
motion from the shaft which drives, the traversing gear of the section builder.
The bobbin creel I prefer to employ is constructed in the form of the letter V,
especially if a large number of ends are being dealt with, the front row of bobbins
being placed parallel with the stop motion and the subsequent bobbins arranged at
an angle as shewn plainly in plan view Fig. 6 so that the ends shall be delivered
from the centre or base outwards on each side to the full capacity of the creel in
a free and open order, each end having a clear path and being free from all liability
of getting entangled with neighbouring threads. This form of creel admits of the
largest number of ends being warped at one time.
After leaving the bobbins the threads or ends of warp pass through the fixed
reed a then over and under the series of tension or friction rollers b and over a
grid or series of slots c into which enter needles or detectors & suspended from each
end of warp, the warp threads after leaving the stop motion being threaded through
the horizontal adjustable heck or reed C in the order required to form the desired
lease, then through the beer reed on the section builder and from thence over a
roller on to the warping mill. The stop motion is brought to a standstill on the
breakage or failure of an end of warp in the ordinary way, the detector or needle d
which has lost its support falling through the grid c on to the rollers e, e¹, which
are geared together and driven by toothed wheels f (shewn in dotted lines) from
the main driving shaft g of the stop motion, the fallen needle thus being carried
between such rollers, and the roller e¹ thereby forced laterally apart from its com-
panion roller and oscillating the levers h, h, on their centres h¹, h', One of said
levers carries at its lower end a finger or stud i (see Fig. 2) which, when the levers
are oscillated as aforesaid, is forced against the knocking off handle ; and pushes
it out of a notch or recess in the bracket whereupon the energy of the spring of
which it is formed carries it forward toward the machine, as indicated in dotted
line in Fig. 2, and by means of a stud or finger / slides the rod m endwise in the
direction of the arrow and, where the driving pulleys are carried by the stop a
motion, moves the strap fork from the fast to the loose pulley to stop the machine,
the motion being conveyed to the driving pulley in this case by strap from a long
overhead drum or pulley on which the strap can slide laterally from end to end
with the movement of the stop motion. On the drawings I have shewn the driving
pulleys supported in a standard fixed to the floor and therefore not moveable with 4
the stop motion, the shaft g on which the pulleys are mounted having a key way
cut therein into which takes a key formed in the hollow shaft n which is adapted
to slide over said shaft g within the limits of the lateral traverse of the platform F,
and thus to derive its motion from the shaft g throughout its whole movement.
The strap guide is actuated by lever and link from the part o¹ of a rocking 4
shaft o, or otherwise, as found most convenient.
The second part of my invention relates to means for stopping the warping mill
immediately an end of warp breaks or fails, no matter to what position between
the ends of the warping mill, the platform F has been moved.
On the sliding rail or rod m is a stud m¹ engaging with the sides of a slot in the 5
upper arm of a bell crank lever p centred at p³, the lower arm of said lever being
connected by rod or link p² to a lever r secured on a hollow shaft o which is bored
to receive a square or angular or flat sided shaft o¹ over which it is free to slide
endwise or telescopically but not to rotate or rock independently. thereof. The
outer end of the part o¹ of the rock shaft is supported in a fixed pedestal or 5
standard and secured thereon, beyond the position occupied by the stop motion
when first commencing to wind the warp on the swift, is a levers having connected

page_text: thereto one end of a rod s¹ whose opposite end is attached to a lever så fast on the
lower end of a vertical shaft t which carries a second lever that its upper end.
When the rod or rail m is forced in the direction of the arrow (Fig. 2) by the
action of the stop motion on the failure of an end of warp, as before described, the
bell crank lever is moved on its centre to the extent denoted, oscillating the hollow
shaft o which consequently rocks the shaft o' and through the medium of lever s
rods and lever actuates the vertical shaft t this causing the lever t¹ to strike
against a projection on the strap fork rod t and slide said rod endwise, by which
means the driving strap of the warping mill is transferred from the fast to the
loose pulley and said warping mill brought to a standstill instantly.
By employing a rock shaft comprising two members whereof one travels with
the stop motion while the other has a fixed position, the said two parts telescoping
into or over each other, and actuating same through intermediate connections from
the knocking off handle, I am enabled to stop the motion of the warping mill
immediately an end breaks no matter to what extent the carriage or platform F
has been traversed towards the opposite end of the warping mill.
My invention relates further to the method of and means for adjusting the heck
or reed C.
I mount each end of the heck or reed on pillars or spindles w which pass through
tubular pedestals or brackets w¹ carried by side frames v. The pillars or spindles w
are provided on one side with teeth into which gear pinions w mounted on a cross
shaft to which is actuated by a hand wheel w mounted on one end thereof. On
the same side of the heck as the hand wheel and secured on said shaft w¹ is a disc w³
having three or other desired number of teeth or projections on its periphery,
according to the number of positions it is required to adjust the heck, three being
the ordinary number. The heck is shewn on the drawings at its mid position in
which position it is held by a detent w. When the heck requires raising or
lowering for forming or striking the lease, the hand wheel 2 is rotated in one
direction or the other thus giving motion to the pinions wat each side which
elevate or lower the heck as the case may be, the detent w engaging with a tooth
on the disc w when the heck has been adjusted to the height required and locking
it in that position. The heck being mounted horizontally, and made adjustable to
suit the position required in striking the leases gives easy access to and control
over same, considerable labour being thereby saved and all strain on the attendant
avoided.
The section reed a on the section builder is made in two parts, hinged together
centrally, each half thereof being secured to a nut through which a screw with
right and left hand thread is adapted to work when turned by the hand wheel c¹
(see Fig. 5) the rotation of the screw opening out, or closing the two halves of the
reed bookwise, this being done for the purpose of varying the width of the section
to be built on the warping mill to any degree desired.
The base carrying the section reed is adapted to be moved endwise in the trough y
by hand wheel and screw yl working through a nut or nuts secured to the said
base.
By combining a creel, stop motion, and "heck" or reed on a moveable base,
with a swift for sectional warping in the manner set forth, a warp containing a
large number of ends can be wound in sections on the swift as easily and
expeditiously as a small number of ends, and the attendant is relieved of the duty
of watching for broken ends and of stopping the machine when they are discovered;
there is no liability of a section being wound on with a broken end in same, and
no necessity for unwinding a few laps of warp and disturbing the structure of the
section in order to find a broken end an evil which hitherto has had to be
contended with in this class of machine.
From the swift the warp can be wound direct on to the beam which is mounted
in bearings at the rear of the swift and the use of bobbins or the like now employed
intermediate of the swift and beam are dispensed with.

page_text: 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. The combination, with a Scotch warping mill, of a bobbin creel, stop
motion, and horizontal adjustable heck or reed all mounted on a carriage or plat-
form movable by hand or otherwise in a direction from end to end of the warping
mill substantially as herein shewn and described.
Secondly. In Scotch or other horizontal warping mills, the combination, with a
stop motion, of a telescopic rocking shaft, such as o, o¹, one portion of which is
movable laterally with the stop motion while the other portion is fixed, together
with the means for actuating same on the failure or breakage of an end of warp
and for actuating the strap fork rod of the warping mill to stop the rotation of
same substantially as herein shewn and described.
Thirdly. The combination with a Scotch warping mill of an adjustable
horizontal heck or reed substantially as shewn and described.
Fourthly. The combination, with a Scotch warping mill, of a V shaped bobbin
creel, a stop motion, a horizontal adjustable heck or reed and means for raising
and lowering same and holding it in position, all mounted on a movable platform
or carriage, the means coupled with said stop motion for stopping the rotation of
the warping mill at any point of the traverse of the carriage or platform, and a
hinged collapsible section reed for beer lease, substantially as herein shewn and
described.
