County of Lancaster, IMPROVEMENTS IN AND MACHINERY FOR SECTIONAL
WARPING
The object of this invention is to perform the sectional warping operation direct
on to the weaver's beam whereby not only the yarn is economised but much time
is saved and the sections hitherto used are entirely dispensed with.
In carrying out my invention I mount the weavers beam in a suitable frame
capable of sliding to and fro upon a bed so as to present different portions of the
beam for the reception of the various sections in front of the half beer reed through
which the yarn passes On this beam I mount a loose flange hinged together in
halves and capable of being clamped securely upon any desired position of the
beam. This flange is provided with an additional flange 50'arranged parallel to
its inner surface and furnished with adjusting screws that it is capable of being
adjusted to run perfectly true with and at the desired distance from the fixed
flange on the beam.
And in order to produce the desired hardness or closeness of the yarn being
wound upon the beam for forming the sections I arrange a drum or pulley to run
in frictional contact with the yarns upon the beam.
This drum which is mounted in suitable slides regulates its own pressure and is
governed by the length of yarn wound on to the section and turns itself back
gradually as the yarn accumulates upon the beam by the action of a suitably
211

aforesaid friction drum.
When one section is thus formed upon the beam the adjustable flange is moved
a suitable distance further along the beam to permit another section to be formed.
thereon and then the beam is moved bodily along the bed so bringing the space 5
for the new section opposite to the half-beer reed when the friction drum is once
more placed in contact and the same operation is repeated until the beam is full
the side of the section acting and formning in this case the flang on one side to
support the new sections whilst being formed.
It will be readily apparent that by this system of beaming the length of yarn 1
forming each section and their diameters are kept exactly the same.

"
The object of this invention is to perform the sectional warping operation direct
on to the weavers beam whereby not only the yarn is economised but much time
is saved and the sections hitherto used are entirely dispensed with.
And in order that this my said invention may be the more readily understood
and carried into practical effect I have hereunto annexed a drawing illustrative
of my improvements and will now proceed to describe the same with the assistance
of the various Figures and letters of reference marked thereon. Fig 1 is a front
view Fig 2 an end view and Fig 3 a plan of my improved machine for sectional
warping.
"
In carrying out my invention I mount the weavers beam a between head-
stoeks band b which are capable of sliding to and fro upon a guide bed c so as
to present different portions of the beam for the reception of the various sections
in front of the half beer reed through which the yarn passes. On this beam
I mount a loose flange e hinged together in halves (as seen dotted in Fig 3 and
more clearly in the sectional view Fig 4 and front view Fig 5.) this flange is
capable of being clamped securely upon any desired position along the beam by the
clamping screw e and is provided with an additional flange e² (see Figs 4 and 5)
so arranged parellel to its inner surface and furnished with adjusting screws f that
it is capable of being adjusted by such screws to run perfectly true with and at
the desired distance from the fixed flange g on the beam a. If the surface of the
beam is turned true then a single flange bored out exactly to fit may be used
instead of the adjustable flange as seen dotted and marked e in Fig 1.
The ends of the yarns to form the section are guided through the half beer
reed d and over the guide roller d¹ and are secured to the beam a in the usual
manner.
Revolving motion is now imparted to the beam a by a strap from any con-
venient motor passing round the driving pulley h keyed upon the driving shaft hi
this driving shaft h' is provided with.a travelling friction bowl 2 which runs in
contact with the face of a friction plate or disc wheel ha keyed upon the inter-
mediate parallel shaft and which in turn by the intervention of the spur gearing
imparts revolving motion to the spindle of the head stock band to the beam a.
And in order to produce the desired hardness, or closeness of the yarn being wound
upon the beam between the flanges e² and g for forming the sections I arrange a
drum or pulley i to run in frictional contact with the yarns so being wound upon
the beam. This drum i which is mounted in suitable slides in the stationery
framework regulates its own pressure and is governed by the length of yarn
wound on to the section and turns itself back or recedes gradually as.
the yarn
accululates upon the beam by the action of a suitably formed cam j driven by worm
and worm wheel and spur gearing from the shaft carrying the aforesaid friction
drum. The drum shaft is is provided with a worm gearing with a worm wheel /c¹
upon the side shaft 2 mounted inside the framework this shaft by means of
the spur gearing communicates motion to the outside shaft and thence through
the worm and worm wheel to the cam shaft this cam shaft at its other
extremity is also geared by the spur wheels to a spindle ja (see Fig 1) which

page_text: carries a spur wheel j (seen dotted behind the head stock b) gearing with a toothed
rack and clutch m connected to the friction bowl h2 and thus such shaft not only
winds back the cam but also performs the function of simultaneously winding
back the friction bowl h² towards the periphery of the disc wheel h³ and so
reduces the speed of the latter and hence reduces the speed of the beam a
proportionally as the yarns accumulate thereon. In other words the surface
speed of the yarns being laid upon the beam to form the sections is thus maintained
constant and unvarying.
When one section is thus formed upon the beam the adjustable flange e is moved
a suitable distance further along the beam a to permit another section to be formed
thereon and then the beam is moved bodily along the bed c by means of the spur
pinion n gearing with the toothed rack O and actuated by the hand wheel p (or
such travelling motion may be obtained by a screw) so bringing the space for the
now section opposite to the half beer reed d when the friction drum,i is once more
placed in contact by disconnecting the worm k and winding back the shaft by.
means of a winch bandle applied to the square extremity of such shaft and the
same operation is repeated until the beam is full the side of the section acting and
forming in this case the flange on one side to support the new section whilst being
formed. To prevent the possibility of the yarn at the upper edge of the unprotected
side of the section being pulled down by the friction of the yarn I find it advisable
to apply a little paste to the yarns at this point. It will be readily apparent that
by this system of beaming the length of yarn forming each section and the
diameters of the sections are kept exactly the same.
Having thus particularly described and ascertained the nature of this my said
invention together with the best methods with which I am acquainted for carrying
the same into practical effect I wish it to be distinctly understood that I do not
confine myself to the precise details relative proportions or dimensions of the
various parts of my improved machine herein before described and illustrated on
the accompanying drawing as the same may be considerably varied without
departing from the invention but what I claim is :-
1st The improvements in sectional warping substantially as hereinbefore
described.
2nd The improved combination and arrangement of mechanism for winding the
yarn in sections direct on to the weavers beam substantially as hereinbefore
described and illustrated on the accompanying drawing.
3rd The mode of and mechanism for imparting the desired hardness and closeness
to the yarns forming the sections and rendering the same equal in diameter
substantially as and for the purposes hereinbefore described and illustrated on the
accompanying drawing.
In witness whereof I the said Henry Yates have hereunto set my hand and
seal this Eighteenth day of September in the year of our Lord One thousand
Eight hundred and Eighty three.
