ALFRED SEELEY, of 27, Smith Street, Rochdale, Commercial Traveller, and
GRINDROD KERSHAW, of 64, Clement Royds Street, Rochdale aforesaid, Draughts-
man, do hereby declare the nature of the said invention, to be as follows:-
Our invention relates to an improved combination or to improved combinations
and arrangements of mechanism applicable to section warping and beaming
section," so that warp
machines for making the yarn or thread wind upon the
sections made after the trial section will be the same, and consists in an arm
secured upon the presser shaft, and a slide bar moving by preference horizontally
in suitable slideways, the said slide bar having an arm attached to or projecting
from it at such inclination diagonal or otherwise as will coincide or be parallel
with the edge of the said arm secured on the presser shaft when that shaft is in
the position it occupies when the section commences to be wound.
This said arm from the slide bar is or may be slotted for a stud which may
carry a swivel block, which stud can be adjusted in such slot or its equivalent,
after or during the winding of the trial section to come or bring the swivel block
against the said arm secured on the presser shaft, by which arrangement all
subsequent warp sections will be equal to the trial section.
The arm on the presser shaft may be slotted, and carry the adjustable stud and
it is or may be adjusted in the slot to come against the edge of the said arm from
the slide bar. The slide bar is actuated from the section shaft by a cam ratchet
and pawl and screw shaft intermittently or continuously by gearing or by other
equivalent mechanism.
The said arm from the slide bar, or the said arm on the presser shaft whichever
carries the adjustable stud may have an index marked upon it so that the operator
can at once set the machine to make similar warp sections to such as have been
first previously made by a trial section, by observing the position of the adjustable
stud in respect to the index when making the trial section, and placing it in the
same position to make similar sections.
In some cases the edge against which the adjustable stud acts may be made
curved or of other desired shape.

Improvements in or applicable to Section Beaming and Warping
Machines,
We, PETER JOEL LIVSEY, of 24 and 25, Queen's Chambers, 5, Market Street,
Manchester, in the County of Lancaster, Consulting Engineer and Patent Agent,
ALFRED SEELEY, late of 27, Smith Street, now of 34, South Street, Rochdale,
Commercial Traveller and GRINDROD KERSHAW, of 64, Clement Royds Street,
Rochdale aforesaid, Draughtsman, 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:
Our invention relates to an improved combination or to improved combinations
and arrangements of mechanism applicable to section warping and beaming
machines for making the yarn or thread wind upon the section so that warp
sections made after the trial section will be the same, and consists in an arm
secured upon the presser shaft, and a slide bar moving by preference horizontally
in suitable slideways, the said slide bar having an arm attached to or projecting
from it at such inclination diagonal or otherwise as will coincide or be parallel
with the edge of the said arm secured on the presser shaft when that shaft is in
the position it occupies when the section commences to be wound.
This said arm from the slide bar is or may be slotted for a stud which may
carry a swivel block, which stud can be adjusted in such slot or its equivalent,
after or during the winding of the trial section to come or bring the swivel block
against the said arm secured on the presser shaft, by which arrangement all
subsequent warp sections will be equal to the trial section.
The arm on the presser shaft may be slotted, and carry the adjustable stud and
it is or may be adjusted in the slot to come against the edge of the said arm from
the slide bar. The slide bar is actuated from the section shaft by a cam ratchet
and pawl and screw shaft intermittently or continuously by gearing or by other
equivalent mechanism.
The said arm from the slide bar, or the said arm on the presser shaft whichever
carries the adjustable stud may have an index marked upon it so that the operator
can at once set the machine to make similar warp sections to such as have been
first previously made by a trial section, by observing the position of the adjustable
stud in respect to the index when making the trial section, and placing it in the
same position to make similar sections.
In some cases the edge against which the adjustable stud acts may be made
curved or of other desired shape.
Fig. 1 is a side elevation of so much of a 'section warping machine as will be
necessary to explain our invention.
Fig. 2, is a front elevation of the slide bar and its slideways and the end of
the screw for actuating it, the ratchet or other wheel on the end of the screw
shaft being omitted from this view.
Fig. 3, is also a front elevation, the slide bar being shown in section in the
line A-B Fig. 1, and all parts to the left of that line in Fig. 1, are omitted.
Fig. 4. is a front elevation and section on the line C-D Fig. 1.
Fig. 5, is an end elevation showing an alternative arrangement of the lever
arm fixed on the presser shaft, and of the arm descending from the sliding bar.
Fig. 6, is a view corresponding to Fig. 5 of another modification. a, is the 4
end frame, which is connected with a similar frame by cross stays and these two
end frames have bearings in them, one for the section shaft b, which overhangs
on one side of the machine and upon this overhanging end of the shaft the section
block, indicated in dotted line, is secured, and it is upon this block that the
warp threads are wound, and against its sides two flanges (one 62, of which is 5

page_text: shown) are secured to confine the warp threads to the width of the block. The
other bearing in the two end frames is for the presser shaft c, which also over-
hangs on the same side of the machine as that for the section."
Upon this overhanging end of the presser shaft, an arm is secured, the centre
line of which is indicated in three positions by dotted lines c, c¹ and c².
The end of the presser arm has a bearing or cradle to carry a cylindrical bowl
which is free to rotate in the cradle bearing for it, and this bowl is represented
by a dotted circle in two positions, one in its position c³, against the surface of
the section block 6', when the warp threads begin to wind upon the section, and
in the other c, at the largest diameter the section can be filled with warp threads.
The parts hitherto referred to by letters of reference are ordinary and well
known and common to section warping machines, other parts of such machines
need not be referred to. The centre of the presser bowl is supposed to move or
may move in the arc from the centre of the section shaft b, shown by dotted line
and the presser shaft c, makes a corresponding movement from the dotted centre
line e, which indicates the position at the commencement of the "section," the
dotted line, the extreme position if filled to the full diameter of the section--
the dotted line c, being the middle position between the two extremes.
There is a lever arm d, secured on the presser shaft c, with its front edge d',
parallel to the dotted centre line c. There is a bar e, arranged to slide to and fro end-
ways in slideways a¹, at each end, formed in projections from or in brackets
secured to the side of the end frame a, and the slide bar is held in the slideways
by plates e and e, secured in front of each slideway by set screws or bolts.
From the slide bar e, an arm e³, descends, and as shown in Fig. 1, this arm has
a slot e, in its lengthway, and the centre line of this slot when the slide bar e, is
in the position for the beginning of the winding of the warp threads upon the
section is exactly opposite to and parallel with the dotted line c
The lever arm d,
in the modification shown by Fig. 1, is nearest the end frame a, of the machine,
and the slide bar e, and its arm e, is on the outside as shown in Fig. 3.
There is a stud e, in the slot in the arm e³, which has a collar inside the arm e³,
and may have a square washer c, on its outside end, which washer may have slight
projections to partly enter the slot so that the square washer will keep parallel to
the slot when moved.
On the outside end of the stud e, there is a screw nut, and if desired a lock
nut, and by means of these nuts the stud may be secured when moved to the
required position in the slot. From the collar of the stud cs, there is a projection
inwards which has or may have a swivel block c, upon it, kept upon its end by
a pin passing through a hole across the projection. One side of this swivel block
is kept against the edge d', of the lever arm d, on the presser shaft.
The swivel block e', may be dispensed with if desired, and the projection from
the stud may be arranged to come directly against the edge d, of the lever arm d,
but the swivel block is to be preferred as presenting a larger surface not likely to
wear away rapidly.
To the slide bar e, and between two ribs upon it a bracket e8 is secured by a bolt
which bracket forms a screw nut for the screw thread of a shaft f, having its
bearing on the plate e¹, for the slideway at that end of the slide bar, or the shaft
may have a separate bearing.
There is a collar on the shaft f, to come against the end of the bearing to resist
pressure that comes upon it caused by threads acting on the presser bowl.
The outer end of the shaft f, has a ratchet wheel f, upon it or other wheel, in
gear with a ratchet, which ratchet is moved at each revolution of the section
haft b, by a cam, the movement from which is transmitted through a lever having
ts fulcrum on the framing.
Or the screw shaft f, may be rotated at the desired speed continuously by
being geared with the section shaft b. The mode of driving the screw shaft f,
rom the section shaft b, may be by any of the known arrangements used in
ection warping machines.

page_text: The screw shaft f, has or may have a crank handle upon its end (not shown) for
screwing back the shaft after making a section to the same starting point, as
is well understood in section warping machines, the gearing if driven continuously
from the section shaft being arranged to be put out of gear while screwing back
the shaft and then put into gear before the winding of the section begins.
When a trial section is to be made, the stud e, is moved to the lower end of the
slot e, in the arm e³, from the slide bar so as to be clear and out of the way of
the lever arm d, while the trial section is being made, but when made the stud e,
is slided up the slot et, until the side of the swivel block e, comes against the
edge, of the lever arm d, then the stud, is secured, and all subsequent warp
sections will be made the same.
On one edge of the descending arm from the slide bar, there may be an index g,
say divided into inches and tenths of an inch marked, and upon one edge of the
square washer, opposite the index, a vernier g¹, so that the position of the stud e,
may be ascertained to say one hundredth part of an inch, which when noted will
enable the warper to fix the stud c, in the same position to make a similar section
to one previously made by that position of the stud, without first making a trial
section. This index and vernier may be more conveniently made on thin metal
and secured to the arm and square washer by screws.
It will be understood that
the slide bar c, moves in the direction of the arrow on Fig. 1, when warping.
Fig. 5 This modification shows the lever arm d, slotted for the adjustable
stude, carrying the swivel block e, to come against the edge of the arm e³, descend-
ing from the slide bar e, the lever arm d, in this case being outside, and the
descending inclined arm e³, inside or nearest the end frame a Fig. 6-In this
modification the relative positions of the lever arm d, and descending inclined
arm e³, are as in Fig. 5, but in this case the lever arm d, is parallel from its end
to near its fulcrum, and a box , fits and can slide upon it, this box having a
set screw ³, in one side of it, which when tightened can be secured by a lock
nut upon the set screw. The side of this box carries a pin d', which projects on
one side of the box, and the swivel block c', is placed upon this pin and is pre-
vented from coming off by a pin passing through a hole across it as shown in
Fig. 3.
In place of the pin d, there may be a projection from the side of the box d²,
and solid therewith.
In the two views Figs. 5 and 6 the lever arms d, are shown in the middle
position between that of the presser shaft when the warp section is empty and
when completely filled.
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
1. The combination of a slide bar having a descending arm, moved by a screw
actuated from the revolutions of the warp section shaft with a lever arm on the
presser shaft and with an adjustable stud as and for the purpose hereinbefore
described and illustrated by the drawings.
2. The combination referred to in Claim 1 as and for the purpose herein before
described when modified as herein before described and illustrated by Fig. 5 or
Fig. 6 of the drawings.
3. The combination of an index with the arm from the sliding bar or lever arm
from the presser shaft and with or without a vernier substantially as and for
the purpose herein before described.
