ROBERT HALL of Bury in the County of Lancaster Engineer and JOSEPH
WALMSLEY of the same place Foreman "IMPROVEMENTS IN SECTIONAL WARPING
AND BEAMING MACHINES"
Our Invention relates to the machinery described in the Specification to Letters
Patent granted to us in conjunction with Samuel Standring Hall on the
14th February A.D. 1880 No. 661 and the objects of our improvements are to
wind all the sections of a warp (whatever the count of yarn may be) to one
uniform diameter and to ascertain with facility and certainty the number of the
change wheel required to produce one uniform diameter of section. In performing
our Invention we employ a friction bowl to drive the friction plate on the section
shaft as described in the Specification No. 661 A.D. 1880 but we use improved
mechanism for traversing the bowl to drive the plate at a positive decreasing speed
as the diameter of the section increases: to the press roller shaft we connect an
elbow lever one end of which is provided with a projection that enters the annular
groove in the boss of the friction bowl and moves it away from the centre of the

shaft we also fit a crown wheel on a feather key that may be moved into or away
from another crown wheel or clutch box loose on the same shaft, the latter crown
wheel has fixed to its boss a lever that is connected to a vertical screwed shaft (or

ROBERT HALL of Bury in the County of Lancaster Engineer and JOSEPH
WALMSLEY, of the same place, Foreman, "IMPROVEMENTS IN SECTIONAL WARPING
AND BEAMING MACHINES"
Our Invention relates to the machinery described in the Specification to
Letters Patent granted to us in conjunction with Samuel Standring Hall on the
14th February A.D. 1880 No. 661 and the objects of our improvements are to
wind all the sections of a warp (whatever the count of yarn may be) to one
uniform diameter and to ascertain with facility and certainty the number of the
change wheel required to produce one uniform diameter of section.
In performing our Invention we employ a friction bowl to drive the friction plate
on the section shaft as described in the Specification No. 661. A.D. 1880 but we
employ improved mechanism for traversing the bowl to drive the plate at a speed
positively decreasing as the diameter of the section increases: to the press roller
shaft we connect an elbow lever one end of which is provided with a projection
that enters the annular groove in the boss of the friction bowl and moves it way
from the centre of the friction plate as the diameter of the section increases. We
fix a lever on the press roller shaft connected to a vertical sliding rod on which is
a finger that moves over a graduated plate to indicate the diameter of the section.
On the press roller shaft we also fit a crown wheel or clutch on a feather key that
may be moved into or away from another crown wheel or clutch loose on the same
shaft the latter crown wheel has fixed to its boss a lever that is connected to a
vertical screwed shaft shaft (or sliding rod) on which is a finger which moves over
the same graduated plate that the first named finger moves over. On the screwed
portion of the vertical shaft we fit a nut which forms the boss of a small wheel to
which motion is communicated by a ratchet wheel actuated by a pawl on a lever
worked by a cam on the section shaft: this ratchet wheel transmits the motion
through the change wheel and a carrier to the nut and by turning it the screwed
rod is raised. The sliding crown wheel is placed out of contact with the crown
wheel connected to the screwed shaft until the first section of warp has been wound
when the difference between the figures indicated by the finger on the first named
sliding rod and by the finger on the screwed shaft will denote the additional
number of teeth to be used in the change wheel: a wheel with a minimum number
of teeth being used for the first section.
The required change wheel is then put on the boss of the ratchet or pegged wheel
and the crown wheels are placed in contact till the remaining sections have been
wound and thus their uniformity is secured. A toothed segment may be fitted on the
presser shaft and a rack on the vertical screwed shaft instead of using the crown
wheels as described. Or two L levers may be fitted on the presser shaft, one loose,
and the other may slide on a feather key: the latter lever being provided at one
end with a pin which may enter a hole in the loose lever which is connected to the
screwed shaft.
And in order that our Invention may be fully understood and readily carried
into effect we will describe the accompanying Sheet of Drawings reference being
had to the Figures and letters marked thereon.
Fig. 1 is a side elevation and Fig. 2 is a plan of a sectional warping and beaming
machine to which our Invention is applied.
Figs. 3, 4, 5 and 6 are detailed views of parts of the same.

rod a² to one end of the elbow lever b fitted on a fulcrum stud b¹. in the other
end of this lever b². is a slot that receives the shank of a guide fork that is free
to swivel and that enters a groove in the boss of the friction bowl c and moves
it away from the centre of the friction plate d as the diameter of the section
increases.
One end of the lever a'. is connected to the vertical sliding rod f on which is a
finger that moves over a graduated plate to indicate the diameter of the section:
On the press roller shaft we also fit a clutch or crown wheel g on a feather key
that may be moved by a lever into or away from another clutch or crown
wheel g¹. loose on the same shaft: the latter crown wheel has fixed to its boss an
Llever i that is connected to the vertical screwed shaft k on which is a finger
which moves over the same graduated plate that the first named finger moves over.
On the screwed portion of the vertical shaft k we fit a nut which forms the boss of
a small wheel to which motion is communicated by a ratchet wheel m actuated
by a pawl n on a lever n¹ worked by a cam on the section shaft: this ratchet
wheel transmits the motion through the change wheel o and a carrier to the nut and

contact with the crown wheel connected to the screwed shaft until the first section
of warp has been wound when the difference between the figures indicated by the
finger on the first named sliding rod fand by the finger on the screwed shaft I will
denote the additional number of teeth to be used in the change wheel, a wheel with
a minimum number of teeth being used for the first section.
The required change wheel is then put on the boss of the ratchet or pegged
wheel and the crown wheels are placed in contact till the remaining sections have
been wound and thus the uniform diameter of each section is secured. A toothed
segment g (see Fig. 6) provided with a clutch may be fitted on the presser shaft
and a rack g³. on the vertical screwed shaft instead of using the L lever i as described.
Or two levers i¹. ². (see Fig. 5) may be fitted on the presser shaft, the lever i is
loose and the lever may slide on a feather key, the latter lever being provided
at one end with a pin which may be moved into or out of a hole in the loose
lever . which is connected to the screwed shaft 1.
Having stated the nature of our Invention and described the manner of
performing the same.
We declare that we claim
1-The mechanism for traversing a friction bowl that drives a friction plate on
the section shaft substantially as and for the purpose herein described and as
shown.
2-The improved mechanism whereby we are enabled to ascertain the number
of teeth required in the change wheel, substantially as and for the purpose herein
described and as shown.
In witness whereof we the said Robert Hall and Joseph Walmsley have here-
