PROVISIONAL SPECIFICATION.
Improvements in Yarn Warping and Beaming Machines.
We, GEORGE WATSON LIGHTOWLER and WILLIAM KEIGHLEY of the Firm
of Lightowler and Keighley of 2, Portland Street, Bradford, in the County of
York, Machine Makers, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in warping-mills or warping and beaming
machines and its primary object is to provide a more accurate measuring device for
indicating the length of yarn wound on the mill.
For this purpose we mount a pair of rollers on the travelling carriage between
which the warp or yarn is passed before going on to the mill. One of these said
rollers is a true cylinder of say exactly a foot in circumference and the other is
preferably a covered roller. The shaft or arbor of the said cylinder is provided
with a worm engaging a graduated worm wheel fitted with an index finger which
may be adjustable. This worm wheel and index finger indicates in yards and feet
the length of warp or yarn passed between the roller. The complete revolutions of
the said worm wheel are recorded by a second worm wheel operated by the same
worm but having a tooth more or less. This second worm wheel may be below the
first wheel and an opening formed in the latter to disclose the graduations on the
lower wheel.
In the case of warping-mills fitted with beaming motions we preferably employ
the arrangement hereinafter described in which the same belt drives both the
warping-mill and the beaming motion.
For this purpose the pinion shaft for driving the warping-mill is driven direct by
a belt in the ordinary way. A loose pulley is placed next to the driving pulley
and on a sleeve next to this loose pulley is secured the pulley for driving the
beaming mechanism. A second pulley on said sleeve may be provided to
communicate motion to the beaming motion or it may be connected thereto by
gearing.

Improvements in Yarn Warping and Beaming Machines.
We, GEORGE WATSON LIGHTOWLER and WILLIAM KEIGHLEY of the Firm
of Lightowler and Keighley of 2, Portland Street, Bradford, in the County of
York, Machine Makers, 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 relates to improvements in warping-mills or yarn warping and
beaming machines and its primary object is to provide a more accurate measuring
device for indicating the length of yarn wound upon the mill.
For this purpose we mount a pair of measuring rollers upon the usual travelling
carriage between which rollers the warp or yarn is passed as it is fed on to the
mill. One of these said rollers is a true cylinder of say exactly a foot in circum-
ference and the other is preferably a covered roller. The said cylinder and
covered roller are operated by the yarn passing between them and acquire the same
CD 037

page_text: peripheral speed as the speed of the yarn and the arbor of said cylinder is arranged
to operate a counting apparatus adapted to indicate in yards the peripheral motion
of the cylinder and consequently indicate the number of yards of warp passed on
to the mill.
In the case of warping mills fitted with beaming motions we preferably employ
the arrangement hereinafter described in which the same belt drives both the
warping mill and the beaming motion.
For this purpose the pinion shaft for driving the warping mill is driven direct
by a belt in the ordinary way. A loose pulley is placed next to the driving pulley
and on a sleeve next to this loose pulley is secured the pulley for driving the
beaming mechanism. A second pulley on said sleeve may be provided to
communicate motion to the beaming motion or it may be connected thereto by.
gearing.
Reference is to be had to the accompanying sheet of drawings forming a part of
this Specification in which similar letters of reference indicate corresponding parts
in each of the figures.
Figure 1, is a side view of such parts of a warping mill as are necessary to
illustrate the application of our improvements thereto.
Figure 2, is a plan view of one end of the machine.
Figure 3, is a front view of the measuring rollers mounted in standards upon the
usual carriage.
The frame A, the mill or swift B, the slide C and carriage D are of usual
construction. On the carriage D we fix a pair of standards E and E' and mount
the flanged roller F (covered with cloth or other suitable material) between such
standards in bearings formed at the bottom of the slots or openings J in the standards.
The cylindrical measuring roller G is mounted in the sliding bearings H fitted
in the parallel slots or openings J and such roller rests upon the roller F. The
yarn or warp passes between the rollers F and G and on to the mill in the manner
represented by the broken line Y Figure 1 so that the yarn partly encircles the
cloth covered roller F and thereby prevents any possibility of yarn slipping
between the rollers without turning them. The roller G measures exactly a foot
in circumference and its arbor K carries a pinion L engaging a wheel M three
times its size mounted on the primary shaft of a Harding or other suitable
counter O carried by the bracket N secured to the standard E. Therefore the
counter records in yards the length of the yarn passed on to the mill B.
We prefer a Harding or other open faced counting apparatus to the one described
in our Provisional Specification.
Warping mills fitted with a beaming motion usually have the beaming motion
driven by an independent driving shaft and belt. To avoid this we drive the
beaming motion from the pinion shaft or driving shaft P of the mill and this shaft
is driven by the pulley Q keyed thereon. A loose pulley R is placed next to Q and
on a sleeve loosely mounted upon the shaft P is secured the pulley S for driving
the beaming motion. A second pulley T fixed on the said sleeve is connected by
the belt U to the beaming mechanism V mounted on the framework A¹. To
drive the beaming motion the driving belt of the warping motion is transferred
from the pulley Qover the loose pulley R on to the pulley S.
The mill B is driven in the usual way from the pinion W on the shaft P engaging
the toothed wheel X fixed on the end of the mill shaft Z.
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. A yarn warping machine having a measuring roller mounted upon the
carriage, substantially as herein shown and described and illustrated in the accom-
panying drawings.
2. The combination with the measuring roller G of the covered roller F,
substantially as herein shown and described and for the purpose specified.

page_text: 3. In a yarn warping and beaming machine, the particular construction and
arrangement shown in the drawings for driving the beaming motion from the
driving shaft of the warping motion.
