Improvements in Sectional Warping Machines.
We, EDWARD HOLLINGWORTH, of the firm of Hutchinson, Hollingworth & Co.,
Limited, of Atlas Works Colne Road, Huddersfield in the County of York,
Machine Makers, and WILLIAM MITCHELL of the same place, Machine Maker,
do hereby declare the nature of this invention to be as follows:-
This invention has reference to machines employed for winding warp in sections
upon a revolving horizontal cylinder or swift, the object of my invention in such
machinery being to make the cylinder stop self actingly when a section of warp
has been wound thereon and completed, and also to improve the machine so that a
longer length of warp can be wound on within a given width or section than
formerly, and to simplify the parts.
In carrying out the first part of our invention, that is to say, the stopping of
the machine when each section of warp has been wound on the swift, we fix on the
shaft of the swift a boss or face plate, on which is a projecting lug so placed that
when the swift has travelled endwise the required distance, the said lug, whilst
revolving, comes into contact with a finger fixed to a cross shaft, which is made to
rock thereby, in doing which the cross shaft acts on the stop rod and transfers the
strap from the fast to the loose pulley and simultaneously therewith the rocking
shaft rings a bell for the purpose of arresting the attention of the workman.
When a section of warp has been wound upon the swift and the machine stopped
in the manner described above, the operative causes the swift to traverse backward
endwise the width of the section or the distance it has already traversed forward,
and this he does by means of a lever attached to a pinion in gear with a toothed
rack projecting from a bracket on the shaft of the swift. A collar on the opposite
end of the said shaft determines the exact distance the swift has to be moved
backward, and instead of employing a self acting or automatic "heck" as is the
case with some sectional warping machines, we employ a "heck" which must be
moved by the workman. To perform this operation accurately, an adjustable
collar is employed on the shaft carrying the heck, which collar must be moved
forward each time the swift is put backward, a suitable form of gauge or distance
piece being used to determine the exact distance the heck must be moved.
In order to cause the swift to move endwise self-actingly whilst revolving, we
place on the end of the shaft (which carries the swift) a sleeve or long boss, having
a screw thread cut thereon, working or revolving in a half nut, which bears upon
the upper half of the screwed sleeve, a toothed wheel is cast or otherwise attached
to the screwed sleeve, which wheel is driven by an arrangement of wheels from the
shaft of the swift but at a different speed, therefore as the swift revolves it is
drawn endwise by the screw running loose thereon, the distance traversed end wise
by the said swift being regulated by change wheels.
By the employment of the screwed sleeve and the regulation of its speed by
change gearing, a much longer length of warp can be wound in a section than
formerly, and this arises in consequence of the swift revolving at one speed and
traversing end wise independently of the rotary motion of the swift, the end wise
Craverse being made more or less according to the number of teeth in the change
wheels.

Improvements in Sectional Warping Machines.
We, EDWARD HOLLINGWORTH, of the firm of Hutchinson, Hollingworth & Co.
Limited, of Atlas Works, Colne Road, Huddersfield, in the County of York,
Machine Maker, and WILLIAM MITCHELL, of the same place, Machine Maker,
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 machines employed for winding warp in sections
upon a revolving horizontal cylinder or swift, the object of our invention in such
machinery being to make the cylinder stop self actingly when a section of warp
has been wound thereon and completed, and also to improve the machine so that
a longer length of warp can be wound on within a given width or section than
formerly, and to simplify the parts.
Such being the nature and object of our invention, we will now proceed to
describe the same more fully, and for that purpose make reference to the accom-
panying sheets of drawings, wherein
Fig. 1 is front elevation of a sectional warping machine having our improvements
applied thereto;
Fig. 2 is end elevation looking in at the left hand of the machine ;
Fig. 3 is elevation of opposite end of machine ;
Fig. 4 is sectional elevation of some of our improved parts, Fig. 5 plan view of
same, and Fig. 6 a detail of the mechanism for operating the strap fork.
The general framework of the machine is indicated at 1 and the swift is shewn
at 2 mounted and secured upon the central shaft 3 upon which is also secured a
large spur wheel 4 gearing with a long pinion wheel 5 driven by driving pulley 6,
the long pinion 5 being necessary in consequence of the shaft 3 together with large
wheel having an end wise motion for winding the warp upon the swift, such
end wise motion being obtained in the following manner :-On the right hand end
of central shaft 3 we place loosely a sleeve 7 kept thereon by the nut 8 which
receives and bears the thrust when the shaft is traversing. This sleeve is supported
and borne by a bracket 9 and it has screw threads formed thereon gearing with
two halves of a nut 10, the upper half of said nut being connected to a lever
arm 11, working upon a fulcrum or stud 12 for the purpose of lifting the upper
half of the nut from the screw when the swift is being put back. This screwed
sleeve 7 is made to revolve independently of the central shaft 3 and at a different
speed according to the section of warp to be wound upon the swift which
independent motion is a new and a peculiar feature in this class of machine. The
screwed sleeve is driven as follows:-Near the right hand end of central shaft 3
is a toothed wheel 13 driving a carrier wheel 14 which communicates rotary motion
to change wheel gearing 15 which in turn drives the spur wheel 16 keyed upon the
screwed sleeve by which it is made to rotate and in consequence of such rotation
the said sleeve is caused to travel through the half nut 10 in the direction of the
arrow 17 in Fig. 4 taking with it the said nut 8 as already stated bearing the
strain of the endwise thrust. During this endwise motion of the swift, the warp
is being wound thereon, issuing from a creel to the feed rollers 18, and when the
section of warp has been completed which a predetermined quantity, occupying
a predetermined width upon the swift, a lug 19 on the face plate 20 fixed upon
the central shaft 3 will come into contact with a finger 21 fixed on a short
horizontal cross shaft 22 which will be made to rock, thereby causing a pin
projecting from a short lever 23 on the said cross shaft to be forced against a
finger 24 rising up from the horizontal bar 25 (see Figs. 1 and 6) causing the
lever 26 to be oscillated upon its fulcrum in doing which the stop rod 27 will be
operated in such a manner as to transfer the driving strap from the fast to the

page_text: loose pulley and the machine stopped thereby and simultaneously with and by such
movement of the oscillating cross shaft 22 a bell 29 attached to the end of a lever
arm 28 is set ringing so as to arrest the attention of the workman. When the
screwed sleeve 7 and swift are moving endwise when winding a section of warp
upon the said swift, a toothed rack 30 which is attached to the bracket 9 is also
moved endwise and the pinion 31 in gear with the said rack is rotated accordingly,
so that before the machine is re-started for winding another section of warp upon
the swift, the operative moves the hand lever 32 so as to rotate the pinion back-
ward, whereby through the medium of the rack, the screwed sleeve and swift are
re-instated or put back the distance they had traversed forward, this being
permitted by the upper portion of the half nut 10 being removed from the screwed
sleeve by raising the handle 11. A collar 33 on the left hand portion of central
shaft 3 determines the exact distance the swift has to be moved backward, such
collar abutting against a boss 34 rising up from the framework (see Fig. 1).
A stationary heck 35 of any suitable construction is employed and carries a reed
in the ordinary manner through which the warp passes previous to being wound
upon the swift, and when the swift has been put back by operating lever 32 as
already described, the heck must of necessity be advanced (in the direction of the
arrow 36 in Fig. 1) the distance of another section. To do this the operative
slackens and moves the collar 37 (mounted on the grooved shaft 38 which also
carries the heck 35) a distance forward equal to the width of a section, a suitable
form of gauge or distance piece provided for the purpose enables him to readily
determine the exact distance, after which the collar 37 is tightened and the nut 39
on the heck 35 slackened to allow him to slide the said heck end wise until it abuts
against the adjustable collar 37, thus the heck is moved stage by stage after the
completion of each section.
When first of all commencing to wind warp on the swift, certain adjustable
inclined plates 40 (on the left hand of the bars composing the swift and shewn on
a large scale in Fig. 7) are separately adjusted to the required angle by thumb-
screw 41 to suit the thickness and number of counts of the yarn to be wound upon
the said swift, and in commencing to wind, the first layer 42 of the first section of
threads is wound upon the swift on a level plane and when the section is completed,
the swift is stopped automatically and the bell rung as already explained. The
second layer of warp 43 is wound upon the swift, the first portion thereof being
wound upon those already laid on the swift and the remaining threads upon the
inclined plate 40, and in like manner some of the threads of the third layer will lie
upon the second layer and others upon the inclined plate and so on, each succeeding
layer leaving a few threads on the inclined plate, and this goes on with each
succeeding section, each section advancing on a preceding section in a regular and
uniform manner so that the sections of warp on the swift are evenly and truly
built up.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
Firstly. In a warping machine, the combined rotary and endwise motions of the
swift, such motions being obtained independently of each other and at different
relative speeds.
Secondly. In a warping mill, the use of a loose screwed sleeve 7, driven in
manner substantially as herein shewn and described for imparting an endwise
motion to the revolving swift.
Thirdly. In a warping mill, the mechanism substantially as herein shewn and
described for automatically stopping the machine when a section of warp has been
completed.
Fourthly. In a warping mill, the mechanism substantially as herein shewn and
described for stopping the machine when a section of warp has been completed, in
combination with a bell for purposes described.

page_text: Fifthly. In a warping mill, the use of the rack 30 and wheel 31 for putting
back the swift or for re-instating the several parts as described.
