Lancaster, Manager, for the Invention of "IMPROVEMENTS
MACHINERY FOR PREPARING COTTON ANd other FIBROUS SUBSTANCES.”
IN
MACHINERY FOR PREPARING COTTON AND other FibroUS SUBSTANCES.
PROVISIONAL SPECIFICATION left by the said William Gudgeon at
the Office of the Commissioners of Patents, with his Petition, on
the 17th February 1875.
I, William GUDGEON, of Rochdale, in the County of Lancaster,
Manager, do hereby declare the nature of the said Invention for "Iм-
IN MACHINERY FOR PREPARING COTTON AND OTHER FIBROUS
PROVEMENTS
SUBSTANCES," to be as follows:-
My Invention is applicable to slubbing frames and other machines of
the like nature in which cones are used for driving the bobbins ; my
improvements consist in a self-acting apparatus for keeping the strap or
straps passing around the said cones at a uniform state of tension.
In performing my Invention I employ a swing frame which is hinged
to and traverses along a fixed bar; this swing frame is weighted to press

page_text: a guide pulley or pulleys against the strap or straps. When the strap
or straps arrive at the end of the cones the tension must be taken off to
allow them to be brought back to the starting point, and this is effected
by means of a cranked shaft which is turned partly round by a shaft
and toothed pinions, or by levers or other equivalents; the crank shaft
acts on the swing frame.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Gudgeon in the Great Seal Patent Office
on the 14th August 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
GUDGEON, of Rochdale, in the County of Lancaster, Manager, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventeenth day of February, in the
year of our Lord One thousand eight hundred and seventy-five, in:
the thirty-eighth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said William Gudgeon, Her
special licence, that I, the said William Gudgeon, my executors, ad-
ministrators, and assigns, or such others as I, the said William
Gudgeon, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an In-
vention for "IMPROVEMENTS IN MACHINERY FOR PREPARING COTTON AND OTHER
'FIBROUS SUBSTANCES," upon the condition (amongst others) that I, the said
William Gudgeon, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and scals, should par-
ticularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Gudgeon, do hereby declare
the nature of my said Invention, and in what manner the same is to

page_text: be performed, to be particularly described and ascertained in and by
the following statement (that is to say) :-
My Invention is applicable to slubbing frames and other machines of
the like nature in which cones are used for driving the bobbins ; my
improvements consist in a self-acting apparatus for keeping the strap or
straps passing around the said cones at a uniform tension.
In performing my Invention I employ a swing frame which is hinged
to and traverses along a fixed bar; this swing frame is weighted to press
a guide pulley or pulleys against the strap or straps. When the strap
or straps arrive at the end of the cones the tension must be taken off to
allow them to be brought back to the starting point, and this is effected
by means of a cranked shaft which is turned partly round by a shaft and
toothed pinions or by levers or other equivalents; the cranked shaft acts
on the swing frame.
And in order that my Invention may be fully understood and readily
carried into operation, I will proceed to describe the accompanying
Sheet of Drawings, reference being had to the figures and letters marked
thereon.
Fig. 1 is an elevation; and Fig. 2, a back view of part of a slubbing
frame to which my improvements are applied. a is the upper cone,
and b the lower one which is driven by the double strap c, and this strap
is traversed from one end of the cones to the other by a screw or by rack
and pinion as usual; d is the swing frame which is hinged to the fixed.
bar e, and this swing frame supports the tightening pulleys ƒ which
press against the straps c and keep them to a uniform tension. When
the swing frame arrives at the end of the cones it is partly raised to lift
the pulleys fand thereby to release the straps by means of the hand
wheel which is actuated from the front of the frame; this hand wheel
is fixed on the upright shaft g¹, to which is keyed the bevel pinion g³
gearing into the wheel h; this wheel is cast with or fixed to the pinion h',
which by means of a carrier gives motion to the wheel i fixed on the
crank shaft . This crank shaft passes through the swing frame d,
consequently when the crank shaft is turned partly round it lifts the
pulleys fout of contact with the straps c, as shewn by dotted lines in
Fig. 1. When the straps have been moved back to the other end of the
cones the crank shaft is turned back to its original position to allow the
pulleys to again tighten the straps.
I

page_text: Figs. 3 and 4 represent a modification of my Invention, in this case
the swing frame d is hinged to the ordinary lifter shaft e, and instead of
tightening pulleys travelling with the straps I employ a roller f of the
same length as the cones. When the straps arrive at the end of the
cones the swing frame d is partly raised to slacken the straps by a screw t
in the shaft g¹ taking into a nut which swivels in an arm of the swing
frame, or by a lever or other equivalents.
Having thus stated the nature of my Invention, and described two
convenient modes of performing the same, I wish to remark that I do
not intend to limit myself to the details given, and that what I claim is 1
raising the tightening pulleys or rollers to release the cone straps by
cranks, levers, or other equivalents actuated from the front of the frame,
as shewn and described.
In witness whereof, I, the said William Gudgeon, have hereunto
set my hand and seal, this 13th day of August, One thousand 1
eight hundred and seventy-five.
