Year: 1870

page_text: LETTERS PATENT to John Bullough, of the Firm of Howard and
Bullough, of Accrington, in the County of Lancaster, Machine
Maker, for the Invention of "IMPROVEMENTS IN SIZING MACHINES."
Sealed the 14th October 1870, and dated the 7th May 1870.
COMPLETE SPECIFICATION filed by the said John Bullough at the
Office of the Commissioners of Patents, with his Petition and
Declaration, on the 7th May 1870, pursuant to the 9th Section of
the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
BULLOUGH, of the Firm of Howard and Bullough, of Accrington, in the
County of Lancaster, Machine Maker, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
SIZING MACHINES," and have petitioned Her Majesty to grant unto me,
my executors, administrators, and assigns, Her Royal Letters Patent
for the same, and have made solemn Declaration that I am the true
and first Inventor thereof.

page_text: NOW KNOW YE, that I, the said John Bullough, do hereby declare
that the following Complete Specification, under my hand and seal, fully
describes and ascertains the nature of the said Invention, and in
what manner the same is to be performed, in and by the following
Statement:
In machines in which the winding on is driven by a pair of cones it is
customary to place a pinion upon the end of the second cone shaft, which
gives motion to an intermediate shaft, which in turn gives motion to a
wheel upon the stud which carries and gives motion to the weaver's
beam. In such machines an eccentric moves the cone strap as the
weaver's beam increases in diameter by means of a screw ratchet wheel
and catch, which moves it a certain number of teeth at each revolution
of the intermediate shaft. But this was only an approximately accurate
method of driving the winding on, and required the constant attention
of the operative in charge. I now in addition to the ordinary breast
beam and sheeting rod place a roller, under which I cause the yarn
to pass, and put the said roller in moveable bearings, which permit it
to rise and fall as the yarn is tightly or slackly being wound on. I
connect one of the moveable arms which sustain the roller to a lever
which controls the catch above described, by which motion is given to
the screw by which the strap is traversed, so that when the moveable
roller descends the yarn being slackly wound on the catch is lifted and
the increasing diameter of the weaver's beam gains on the delivery. On
the other hand when the winding on is too tight, the moveable roller is
raised and the catch permitted to gear into the ratchet wheel, and by its
constant oscillation to move the strap to a slower relative part of the
cones, and so reduce the winding on.
And in order that my Invention may be fully understood and more
readily carried into effect, I will now procced to describe the same,
reference being had to the accompanying Drawing, in which Figure 1 is
a side elevation; and Figure 2 is a plan of part of a sizing machine having
my improvements applied thereto.
a is the first cone shaft, upon which is placed the cone a 1. From
cóné a 1 a strap a 4 is passed to the second cone a 2 on the shaft a 3.
On the end of the second cone shaft I fix a pinion 6 giving motion to
the wheel 61 on the intermediate shaft 6 2. To this shaft, I also fasten
the pinion 63 which gives motion to the wheel 64 fastened on the

cross shaft as described and shewn, whereby the liability of the roller to
get askew is obviated.
In witness whereof, I, the said John Bullough, have hereunto
set my hand and seal, this Seventh day of May One thousand 5

page_text: shaft which carries and gives motion to the weaver's beam in the usual
manner. The strap a 4 is moved by means of the screw a 5, which in
turn is moved by means of the ratchet wheel a 6 and catch a 7. The
catch a 7 is placed- loosely upon the stud a 8 in the L lever a 9 on the
stud a 10 in the framing. The other arm of the L lever a 9 is caused to
oscillate by means of the eccentric 65 fastened on the intermediate
shaft. In ordinary working the catch a 7 is continually changing the
position of the strap, which by the plans heretofore adopted requires to
be controlled and adjusted by the operative in-charge.
By my improvement this is rendered unnecessary in the following
manner: I connect the catch a 7 to one end of the lever d, the outer
end of which rests against one end of the weighted roller f, which roller
is carried by arms d fixed to a shaft d* with which the weighted roller
f and arms d are free to oscillate as required. Under tlie weighted
roller I cause the yarn to pass. I place this roller f in any convenient
position, but prefer it being placed between the breast beam h and the
sheeting rod h 1, so that when the yarn is too slack the roller descends,
when too tight it rises, and when it descends, as described, it raises the
catch a 7 from the ratchet a 6, and causes the motion of the screw a 5
to cease; in like manner when the yarn is too tight it rises and places the
catch a 7 in gear and permits it to move the ratchet a 6 and screw a 5,
thus placing the strap upon a slower driving portion of the cone.
By the motion thus adjusted I am enabled perfectly to regulate the
pressure of the yarn upon the weaver's beam and to make the speed
of the winding on to coincide with the delivery of the yarn at any
determinate speed. The same principle of regulation applies equally to
machines where the winding on is driven by friction plates. I connect
the regulating roller by means of a rack to a wheel nut on the screw by.
which the friction plates are pressed or released as the roller rises or falls
as herein-before described.
Having now described the nature of my said Invention, and the manner
in which the same is to be performed, I declare that I claim as secured
to me thereby,-
Firstly. Rendering the motion which the regulating roller derives
from the variable tension of the yarn available for adjusting the strap
upon the cones or the pressure on the friction plates, so that the winding
on of the yarn shall coincide with the positive delivery thereof.
