Beaming Machines.
I JOHN BETHEL of 7 Gerald Road Pendleton in the County of Lancaster Mill
Manager do hereby declare the nature of my invention for IMPROVEMENTS IN OR
APPLICABLE TO SECTIONAL WARPING AND BEAMING MACHINES 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 the equalization of the diameters of all the sections of a warp and of the
length and tension of the yarn in each section.
And in order that this Invention may be more readily understood and carried
into practical effect I have hereunto appended' a sheet of drawings marked with
letters and numerals of reference similar letters and numerals denoting similar parts
in each of the Figures.
Fig 1 is a side view and Fig 2 is a plan of the apparatus having my Improve-
ments applied thereto.
In carrying out my Invention I secure upon the presser shaft a, a lever b. of any
convenient form or length which is provided with a slot e within which the stud
is capable of sliding and of being secured by a nut at any desired point. Upon a
shaft stud or pine carried in a suitable bearing in the framing and above the free
end of the lever is secured the sector lever which is provided with a slot h
similar to the slot in lever b and carrying a stud y capable of being fixed in any
desired position similarly to the stud d. Each of the slots and h may be
graduated for the purpose hereinafter described. The positions of the fulcra or
centres of motion a. e. of the lever and sector lever are unimportant but they
must be placed relatively to each other so that the are of the sector lever is over
or near to a, and the centre of motion of the sector lever is over or near to the free
end of . The lever and sector lever moreover must be so arranged relatively to each
other that before starting the machine at the commencement of winding a Section,
the slots c. h are parallel to each other. The lever b. and sector lever are jointed
together by means of the link i which may be in one piece and provided with eyes
at its opposite ends to pass over the studs d. g. or it may be secured to the studs
and be jointed in any part of its length so that the two parts may be separated
when required for the independent movement of the lever b or sector lever. The
Prine S

page_text: are of the sector lever has secured to or formed upon it the teeth gearing with
the worm k. Upon the worm shaft is keyed a ratchet wheel actuated by the
pawl m. which receives its motion through the lever . from the cani o. upon the
section shaft p. Motion may be imparted to the sector lever from the section
shaft by any equivalent means that will secure an equal angular motion for the
sector lever for every revolution of the section shaft. The lever . being secured
to the presser shaft will when disconnected from the sector receive a motion
equivalent to that of the presser arm which is also secured to the same shaft.
That is to say, the lever will have an angular motion governed by the increasing
diameter of the section.
If the machine is driven directly by the section shaft p, the gradually increasing
diameter of the section would cause the yarn to be wound thereon at a gradually
increasing speed and the object of my Improvements would not be attained. To
equalize the speed of the yarn I drive the section shaft at a gradually reduced
speed by means of the face plate s mounted on the section shaft. The face plate
may be driven by one or mere to friction bowls mounted on the shaft or
shafts . '. The shaft or shafts are fitted with a feather or fust key and the
eyes of the friction bowls have corresponding keyways so that while the bowls
may slide upon the shafts they are coinpelled to turn therewith. The hubs or
bosses of the bowls have grooves turned upon them into which the fork or
forks engage. These forks are formed upon the ends of arms w. l. keyed
upon the pin or axis a. to which is also secured the arm or lever parallel to a
similar lever y secured to e. The arms or levers y. 2. are provided with slots
through which they may be secured together by a bolt or stud. These two arme
having their centres of motion at opposite ends and being pinned together by the
stud will have equal angular motion if one of them is moved, when the stud
is equidistant between their contres of motion. If however the stud is placed
nearer to one centre then to the other the angular motions will be unequal and the
one arm will move through a longer are than the other. Motion is imparted from
the section shaft through the cam, lever, pawl, ratchet wheel, worm wheel and
sector lever to the lever y, thence through the stud to the lever and the fork or
forks, which, engaging with the friction bowl or bowls moves these towards
the circumference of the disc or face plates as the section increases in diameter
and consequently the section is driven at a correspondingly reduced speed. The
ratio of speed to diameter may be varied by altering the position of the stud :'ns
hereinbefore described along the slots in the levers y. z.
The machine is driven by a belt passing round the drum 1 or 2, fixed upon the
friction howl shaft or shafts and when two bowls are used their respective shafts
may be geared together by the equal spur wheels 3. 4.
When the presser is in contact with the empty section block 5 and the sector is
at its starting point the slots c. . must be parallel to each other. To invariably
socure this position the slots are graduated and the link i has a small pointer at
each end. The length of the link and the graduations have such dimensions and
arrangement that when the two studs and link are secured to corresponding
numbers on the graduated scales they are in such a position that when the sector
lever is brought back to its starting position the slots e. h. are parallel with each
other.
It is advisable to use the shortest possible link and if it is in two parts a line
or other mark on each part should be made to indicate the position in which they
should be re-connected to their proper total length after they have been separated.
The connecting link i being attached by movable stuils to the lever and the
sector lever, the presser may be made to recede to any required distance from the
centre of the section shaft for a given number of revolutions of the section by
varying the positions of the studs 9. d. From the arrangement of the sector lever t
lever b and link i as described, it will be seen that when the link is moved along the
slots in the levers it will at the same time approach the centre of motion of one lever and
recede from the centre of motion of the other.

page_text: In effect this variation of the relative motions of lever and sector lever is
produced by similar means and in a similar manner to those herein before described
in relation to the levers y. z.
The levers y.. and the fork-r-arms w or arms w w are so arranged on the shaft -
that when the sector lever is at its starting position the slots in the levers y and. must be.
parallel with each other and the friction bowl or bowls must be in such a position that
the distance of their point or points of contact with the face plate from the centre
of the section shaft is equal to the radius of the empty section block.
The Sector lever and the lever and the levers y.. may be in any convenient
position relatively to each other and to themselves, provided that the levers in each
pair have their centres of motion at opposite ends or radiate in opposite directions and
that the slots of each pair are parallel to each other when the sector lever is at the
starting point, the presser is in contact with the empty section block and the friction
bowls are at a distance from the centre of the section shaft equal to the radius of
the section block. When it is inconvenient through a modification of their arrange-
ment to connect the levers and y by the shaft . they may be connected by links,
gearing or other equivalent means. If are placed parallel to each other similarly
toy the link may be dispensed with, together with one of the studs and the lever
and sector lever may be connected through their respective slots e. h. by a single
stud as described for the levers y = From the arrangement of the sector lever f, lecer b
and their single connecting stud (when this is used instead of the link i) as described, and
also from the arrangement of the levers y, z and their connecting stud z' as described, it
will be seen that when either of the studs is moved along the slots of the corresponding
pair of levers it will at the same time approach towards the centre of motion of
of the pair and rerede from the rentre of motion of the other.
The method of using the apparatus is as follows:-
one lever
Before the first Section is wound, the slots e. h. are brought parallel to each other
as hereinbefore described. The link i or its equivalent stud is then removed and
the section wound to the required length when the slots e. h. will be found to be no
longer parallel with each other. If the link is employed it will be then necessary
to remove one or both the studs g. d. to such a position or positions as will permit
the link to be replaced on the studs or to be connected together at its indicated
length. If the lever and sector lever have relative positions corresponding to the
relative positions of the levers y. they are connected together by the stud at the
point of intersection of their slots. When the sector lever and lever bare recon-
nected after winding the first section it will be found that they are connected
together in such relation to each other as will, in winding subsequent sections,
invariably cause the presser to recede from the centre of the section shaft similar
distances for similar numbers of revolutions of the section and in consequence all
the sections will be of the same diameter for the same number of revolutions and the
same length of yarn.
To find the correct position for the stud er studs in levers y . for the purpose of
imparting a differing rate of speed to the section shaft inverseley to the increasing
diameter of the section of warp and securing a uniform speed for the yarn it is
only necessary after the trial section has been wound to move the stud er studs to
such position or positions in the slots as will place the friction bowl or bowls in
contact with the face plate at a distance from the centre of the section shaft equal
to the radius of the completed section.
In tightening the links or studs the lever b. may be liable to move from its
proper position. In order to indicate whether the lever has moved the are piece 6
is provided having a pointer 7. This pointer is adjusted to a mark on the end of
lever b. after the first Section is wound and should still point to the mark after the
Sector and lever . have been secured to each other.
Having now particularly described and ascertained the nature of this my Invention
and in what manner the same is to be performed I wish it to be understood that I am
aware that in Sectional Warping and Beaming Machines two lerers connected together

page_text: by an adjustable connection so that the relative extent of the angular movement of the tico
levers can be varied hure been preciously used for the purpose of transmitting positive
movement to the presser by the rotation of the section shaft, and that I do not claim
generally the use of such connected levers either for this purpose or for obtaining
uniformity in the speed at which the thread is wound on the warp sections but I declare
that what I claim is:
(1) In a Sectional Warping and Beaming Machine the sector lever and the
lever in combination with their movable connecting link or an equivalent stud
for the purpose of transmitting a positive motion to the presser from the section
shaft substantially as hereinbefore described and set forth and as indicated on the
accompanying sheet of drawings.
