Sectional Warping and Beaming Machines.
We, GEORGES BURGESS and HUGH DAVENPORT LEDWARD of Wardley Mill,
Walkden, Manufacturers, and JOHN CROMPTON of 114 Longcauseway, Farnworth
near Bolton, Designer, both in the County of Lancaster, do hereby declare the nature
of our said invention to be as follows:-
This invention relates to sectional warping and beaming machines and has for its
object that of regulating the tension of the yarn and the equalization of the diameter
of all the sections of a warp of a given length so as to cause each section to contain
the same amount of yarn, thereby making a more perfect warp than hitherto.
This we accomplish by mounting on the ordinary presser lever shaft a suitable
slotted lever which works in conjunction with an inverted slotted lever hung from a
pin or centre in line with the centre of the presser lever shaft or centre. The slotted
levers are provided with links and levers of suitable lengths to form a parallel motion.
The links are attached to a crosshead mounted on the end of a screw, the threads of
which work into screw threads formed within the boss of a ratchet wheel; the latter
being supported by a bracket from the framework of the machine, and is prevented
moving longitudinally thereby. The screw is provided with a handle, or its equivalent,
by which the same may be rotated when requisite. The ratchet wheel is operated by
"pawl" from the section shaft or otherwise. The slotted levers are connected by a
stud when commencing to form a section and which as the screw is revolved the
stud operates both slotted levers thereby giving a positive regulating motion to the
presser. The sections are carried and operated in the usual manner.

.
The method of using the apparatus is as follows:-When a section is completed the
screw is rotated backwards by the handle, or its equivalent, until the presser is
brought into contact with the empty section block, at which point the two slotted
levers are parallel or in line with each other. The connecting stud is then removed
and the running of a trial portion of a section is proceeded with when it will be found
that the two slotted levers act independently of each other, and as the winding of the
yarn is proceeded with they will show the relation which they must bear to each other
in order to maintain the same tension or diameter of the section throughout the warp.
Immediately this is ascertained the connecting stud is replaced by being bolted to the

page_text: inverted lever, the opposite end projecting into the slot of the bottom lever by which
the motion becomes positive and the presser is caused to recede from the section
exactly the same distance for the same number of revolutions in each of the sub-
sequent sections wound. The position in which the stud is secured in the slot of the
top lever determines the relation of the slotted levers to each other which effects a
corresponding increase or decrease in the speed at which the presser recedes from the
centre of section shaft in proportion to the speed of the screw, which may be noted
by means of a graduated scale on the side of the inverted lever, thereby determining
the position of the connecting stud for a given weight of warp without the necessity
of running a trial section for subsequent warps.

Sectional Warping and Beaming Machines.
We, GEORGE BURGESS and HUGH DAVENPORT LEDWARD of Wardley Mill,
Walkden, Manufacturers, and JOHN CROMPTON of 114 Longcauseway, Farnworth
near Bolton, Designer, both in the County of Lancaster, do hereby declare the
nature of our said 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 and beaming machines and has for its
object that of regulating the tension of the yarn and the equalization of the diameter
of all the sections of a warp of a given length so as to cause each section to contain
the same amount of yarn, thereby making a more perfect warp than hitherto.
This we accomplish by mounting on the ordinary presser lever shaft a suitable
slotted lever which works in conjunction with an inverted slotted lever hung from a
pin in centre line with the centre of the presser lover shaft or centre. The slotted
levers are provided with links and levers of suitable lengths to form a parallel motion.
The links are attached to a crosshead mounted on the end of a screw, the threads of
which work into screw threads formed within the boss of a ratchet or other wheel;
the latter being supported by a bracket from the framework of the machine, and is
prevented moving longitudinally thereby. The screw is provided with a handle, or
its equivalent, by which the same may be rotated or traversed when requisite.

The ratchet or other wheel is operated by a "pawl" from the section shaft or
otherwise. The slotted levers are connected by a stud when commencing to form a
section, and which as the screw is revolved or traversed the stud operates both
slotted levers thereby giving a positive regulating motion to the presser. The
sections are carried and operated in the usual manner.
Fig. 1 is a part side elevation of a sectional warping and beaming machine with
our improved positive and automatic regulator applied and set in position when
commencing to wind a section-Fig. 2 is a plan of same.
;
A is the framework of the machine; B the section shaft; the section block ;
D the presser E the presser lever, and F the presser lever shaft. On the presser
lever shaft F is mounted the slotted lever G which works in conjunction with the
slotted lever H hung from the pin or centre 1; the latter being in line vertically with
the shaft F. The slotted levers G and H are connected by the stud T, as in Figs. 1
and 2, when commencing to wind a section and which as the spur wheel P and the
nut N are revolved the screw L is traversed in the direction indicated by the arrow,
when the levers G and H assume the position shown in Fig. 5 according to the
increased diameter of the section being wound, thereby producing a positive
regulating motion to the presser D. To the lever H is attached the link J coupling
the same with the socket or fork K on the end of the screw L. The socket or fork K
is also connected to the lever M mounted on the shaft F by the link Z by which a
parallel motion is formed. This parallel motion is formed by making the distance
from the shaft F to the centre 10 equal to the distance from the centre I to the
centre 12, and the distance from the centre of the pin 12 to the centre of the pin 16
is equal to the distance from the centre of the pin 10 to the centre of the pin 16.
The screw L passes through the internally chased nut N mounted in the fixing O
secured to the frame A. The spur wheel P is mounted on the nut N and is revolved
by the spur wheels Q and R, the latter being driven. by the worm S on the section
shaft B. The levers G and H can be graduated as in Fig. 1 to facilitate the setting
of the stud T..
The method of using this apparatus is as follows:-When a section is completed
as in Fig. 5 it is removed and the spur wheel Q is slid out of gear with the spur
wheels P and R as in Fig. 4, then the screw L is traversed backwards by turning
the handle U until the presser D is brought into contact with the empty section
block C as shown in Figs. 1 and 2, at which point the levers G and H are parallel
or in line with each other. To the handle U is attached the spur wheel ▼ which
gears into the index wheel W, the latter gearing into the spur wheel P. When a
section is being wound the handle U and wheel V can be slid out of gear with the
index wheel W as in Fig. 2. Fig. 3 is a front elevation of the gearing for operating
the wheel P from the section shaft B.
When it is necessary to run a trial portion of a section the connecting stud T is
removed, when it will be found that the levers G and H act independently of each
other, and as the winding of the yarn on the section is proceeded with they will show
the relative position they must bear to each other in order to maintain the same
tension or diameter of the section throughout the warp. Immediately the position
of the levers is ascertained the connecting stud T is replaced in the slots as in
Figs. 1, 2, 5, and 6, and bolted to the lever H, the opposite end of the stud pro-
jecting into the slot of the lever G, by which the motion becomes positive and the
presser D is caused to recede from the section exactly the same distance for the same
number of revolutions in each of the subsequent sections wound. The position in
which the stud T is secured in the slot of the lever H determines the relation of the
levers G and H to each other which effects a corresponding increase or decrease in
the speed at which the presser recedes from the centre of the section shaft B in
proportion to the speed of the screw L which may be noted by means of the
graduated scale on the levers G and H, thereby determining the position of the
connecting stud T for a given weight of warp without the necessity of running a
trial section for subsequent warps.
Fig. 6 is a side elevation of another modification of our invention wherein the

page_text: screw Lis operated by the ratchet wheel Y in lieu of the spur wheel P in
Figs. 1, 2, 3, 4, and 5. The ratchet wheel Y is mounted on the nut N; the latter
being supported or carried by the fixing O on the frame A. The ratchet wheel Y is
operated by the "pawl" X pivoted to the lever L'. The lever L' is mounted on the
centre M attached to the frame A and is operated or oscillated by the grooved
cam S¹ which is securely fastened on the shaft B as in Fig. 7. To prevent the
ratchet wheel Y reversing its action during the winding of a section by the movement
of the "pawl" X the catch. C₁ is mounted on the centre M¹ being held in position
against the ratchet wheel Y by the weighted end N¹. When it is desired to traverse
the screw L backwards the ratchet wheel Y is released from the "pawl" X and the
catch C by raising the weighted end N¹ and placing the pin P¹ mounted thereon in
the slot D in the arm K' attached to the "pawl" X, which has to be depressed thus
causing the "pawl" X to rise clear of the ratchet wheel Y when it can be turned by
hand or other suitable means to the position shown in Fig. 1 ready for commencing
a fresh section.

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 :-
:―
