PROVISIONAL SPECIFICATION.
Improvements in Expanding Rollers for Stretching Textile Fabrics.
We, CHARLES LOXTON JACKSON of Wharf Foundry, Engineer, and JAMES
EDGE of 35 Wynne Street, Draughtsman, both of Bolton in the County of
Lancaster, do hereby declare the nature of our said invention to be as follows:-
This invention relates to improvements in expanding rollers employed in
machines for operating on textile fabrics and has for its object that of strengthening
the same and to prevent the toothed stretching plates becoming deranged, displaced,
warped or twisted in the joints or wearing parts to ensure of an even and perfect
stretch on the fabric under operation. To effect this we mount on a shaft or
centre a barrel, which may be either solid, hollow, or built up sectionally or other-
wise of any suitable metallic materials, and provided with stays or supports of any
convenient form to receive the toothed stretching plates. The latter are provided
with preparations to slide in the recesses on the stays or supports. In the centre
or thereabouts of the expanding roller is mounted a plair disc on which the
interlocking ends of the toothed stretching plates slide to support the same and
ensure of an even sliding action. The positions of the toothed stretching plates
can be altered at will by means of worm or other gearing and apparatus suitably
mounted and attached in any convenient manner to the swivelling ends mounted on
the said shaft or centre.

Improvements in Expanding Rollers for Stretching Textile Fabrics.
We, CHARLES LOXTON JACKSON of Wharf Foundry, Engineer, and JAMES
EDGE of 35 Wynne Street, Draughtsman, both of Bolton in the County of
Lancaster, do hereby declare the nature of our said 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 expanding rollers employed in
machines for operating on textile fabrics and has for its object that of strengthening
the same and to prevent the toothed stretching plates becoming deranged, displaced,
warped, or twisted in the joints or wearing parts to ensure of an even and perfect
a shaft or
stretch on the fabric under operation. To effect this we mount on
centre a barrel, which may be either solid, hollow, or built up sectionally or other-
wise of any suitable metallic materials, and provided with stays or supports of any
convenient form to receive the toothed stretching plates. The latter are provided
with preparations to slide in the recesses on the stays or supports. In the centre
or thereabouts of the expanding roller is mounted a plain disc on which the inter-
locking ends of the toothed stretching plates slide to support the same and ensure
of an even sliding action. The positions of the toothed stretching plates can be
altered at will by means of worm or other gearing and apparatus suitably mounted
and attached in any convenient manner to the swivelling ends mounted on the said
shaft or centre.

page_text: On the shaft or centre A we mount the barrel B, which may be hollow as shown,
or solid, or built up sectionally, or otherwise, and may be made of any suitable
metallic material or materials. The barrel B is provided with the stays or
supports C to receive the toothed stretching plates D. The stays or supports C
are provided to prevent the toothed stretching plates D becoming deranged,
displaced, and warped or twisted in the joints or wearing parts, to ensure of an even
and perfect stretch on the fabric under operation. The toothed stretching plates D
are fitted with the preparations E to slide in the recesses in the stays or supports C
on the barrel B. The centre, or thereabouts, of the barrel B is provided with the
plain disc F, on which the interlocking ends G of the toothed stretching plates D
slide to support the same, and ensure of an even sliding action when moved in either
direction. The toothed stretching plates D are attached to the swivelling ends G¹
in the usual manner; the latter being operated by the rods H mounted in the
bearings or supporting fixings M employed for carrying or supporting the shaft or
centre A of the expanding roller. The rods H are fitted with the toothed nuts I
gearing into the worms K on the shaft or centre A. Each end of the shaft or
centre A. is fitted with the nut N to rotate the same by means of a box-key or
other equivalents, for the purpose of operating the worms K, to cause the nuts I to
move in either direction as desired or necessary to operate the swivelling ends G¹
connected therewith by means of the rods H. The fixings M are fitted with the
bushes P, through which the rods H pass, and are locked, after the full side of the
opener has been placed in position, by the nuts O.
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 :-
In an expanding roller for stretching textile fabrics, the combination with toothed
stretching plates, a shaft or centre, bearings or supporting fixings, swivelling ends,
and means for operating the same, of a barrel provided with stays or supports and a
centre disc, substantially as described and for the purposes specified.
