Improvements in and relating to Expansion Rollers or Drums for
Levelling Yarn on Beams.
I, JOHN HOLT of 4, Lindsay Street Burnley in the County of Lancaster
Blacksmith, do hereby declare the nature of this invention to be as follows:-
This invention relates more particularly to Beaming Frames and is designed to
remedy the defect of heaping the yarn at the sides of tapers beams during the process
of winding or beaming.
For this purpose, the driving roller or drum, on which tapers beams are supported
and actuated by frictional contact with the drum, I construct of two or more sections,
part of which are fixed to the driving shaft, whilst the others are loose or movable
thereon. Each section is formed with a serrated or corrugated surface, so arranged,
that as the drum revolves the serrations or the like will mount each other and cause
the drum to expand end wise and bear against each flange whereby the sides are pressed
or levelled equal with the other portion of the yarn being wound. The sections of the
drum having expanded to the extent determined by the flanges will each revolve at
one rate of speed as the serrations are now incapable of further mounting each other,
through "slip."
To assist the serrations in expanding the sections of the drum, a spiral or other
suitable spring may be use between each section, in some cases it may be advisable to
dispense with the serrations, and depend solely upon the springs for the expansion of
the sections.

I, JOHN HOLT of 4, Lindsay Street, Burnley, in the County of Lancaster,
Blacksmith, 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 more particularly to Beaming Frames, and is designed to
remedy the defect of heaping the yarn at the sides of taper's beams, during the
process of winding or beaming.
For this purpose, the driving roller or drum, supporting and actuating the yarn
roller or taper's beam by frictional contact, I construct in two or more sections, part
of which may be fixed to the driving shaft; whilst the other are loose and movable
thereon. Each section is formed with a serrated, corrugated or inclined surface at
the edge, in such a manner, that as the drum revolves, the serrations or corrugations
on the fixed sections, engaging with the serrations or corrugations on the other, will
have a tendancy to move the loose sections laterally upon the driving shaft, on which
they are mounted, until arrested by the beam flange. The sections being now
incapable of further expansion, revolve together at one uniform rate of speed.
assist the serrations or corrugations to expand the sections, a spiral or other suitable
spring may be used between the sections."
To
The serrations or corrugations may, if desired, be dispensed with, when each
section of the drum may be mounted upon a midfeather or key fixed to the drum
shaft, so as to be capable of sliding laterally thereon, when so actuated by a spring
suitably disposed between the sections.
And in order that my invention may be properly understood, and readily carried
into, practical effect, I have hereunto attached the accompanying sheet of drawings,
marked with figures and letters of reference. Figs. 1 and 2 are elevations of, a
beaming frame, constructed in accordance with my invention. A is the framework,
B the driving shaft, C a fixed section of the drum secured to the said shaft, on which
is loosely mounted the sections D and E, provided with serrated edges D¹ and E¹,
which engage respectively with the serrations (1 and C2 formed on the edges of the
fixed sections.
In Fig. 1 the sections composing the drum are shewn in their most contracted form.
It will be obvious, that as the fixed section C revolves and drives the yarn roller F,
the inclined teeth or serrations of the fixed section will tend to move the loose sections
of the drum laterally against the flanges F1 and F of the yarn roller F, as shewn in
Fig. 2. The drum is thus rendered capable of adapting itself to any slight variation

page_text: in the width of the yarn rollers or taper's beams being used. The spring or springs G
may, if desired, he substituted for the serrations to expand the sections, or to assist
the serrations in expanding them.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is
1. The employment of an automatic expanding driving roller or drum for beaming
frames, constructed substantially as described for the purpose specified.
