Year: 1877

page_text: LETTERS PATENT to James Dyson, of Nelson, near Burnley, and Peter Bury,
of Manchester, both in the County of Lancaster, 101 the Invention of "IM-
PROVEMENTS IN THE METHOD OF AND APPARATUS FOR CRIMPING FABRICS"
Sealed the 6th April 1877, and dated the 26th January 1877
PROVISIONAL SPECIFICATION left by the said James Dyson and Peter
Bury at the Office of the Commissioners of Patents on the 26th January
1877
JAMES DYSON, of Nelson, near Burnley, and PETER BURY, of Manchester, both in
the County of Lancaster "IMPROVEMENTS IN THE METHOD OF AND APPARATUS
FOR CRIMPING FABRICS"
This Invention relates principally to a novel method of and apparatus for
crimping fabrics known as "Arabian stripes,' a material manufactured from unsized
hard twisted yarn, and which has a tendency when wet to "cockle" oi shrink
but other fabrics may also be readily crimped by the same process
up,
We provide a steam chest which is supplied with steam through a pipe placed at
the bottom thereof, above which is a perforated partition for the steam to pass
through On the top of this chest we mount a series of plain and fluted rollers,
the former act as guides for the material, and the latter as feeders and cumpers
The fluted rollers are placed in bearings one above another, and revolve by
frictional contact, one of which is driven by a strap and pulley.
When it is desired to crimp the material it is passed over the guide rollers and
between the two (or more) fluted rollers, where it becomes crimped, and thence
through a narrow opening on the top of and into the steam chest, it is then spread
backwards and for waids by the operative with a rod through a narrow opening
in the side thereof until it becomes saturated with the steam, it is then removed
through a door at the end of the chest and allowed to dry without being stretched

page_text: until it is "set" By this arrangement the fabric is regularly and evenly crimped
throughout the whole length of the piece, which gives it a much better appearance
and enhances its value to a very great extent.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said James Dyson and Peter Bury in the Great Seal Patent Office
on the 25th July 1877
JAMES DYSON, of Nelson, near Burnley, and PETER BURY, of Manchester, both in
the County of Lancaster "IMPROVEMENTS IN THE METHOD OF AND APPARATUS
FOR CRIMPING FABRICS
"
This Invention relates principally to a novel method of and apparatus for
camping fabrics known as "Arabian stripes," a material manufactured from unsized
hard twisted yarn, and which has a tendency when wet to "cockle" or shunk up,
but other fabrics may also be readily camped by the same process.
We provide a steam chest which is supplied with steam through a pipe placed at
the bottom or side thereof, above which is a perforated partition for the steam to
pass through On the top of this chest wo mount a series of plain and fluted tollers,
the former to act as guides for the material, and the latter as feeders and cumpers
The fluted rollers are placed in beanings one above another and revolve by
frictional contact, one of them being driven by a stiap and pulley
Such being the nature and object of our said Invention, we will now describe
in detail the manner in which the same is to be or may be performed or carried
into practical effect, and in order that the same may be clearly understood we have
annexed hereunto a Sheet of Diawings illustrative thereof, and have marked the
same with figies and letters of reference corresponding with those in the following
explanation thereof
-
Fig 1 in the annexed Diawing is a perspective view, and Fig 2, a vertical section
of the apparatus which we employ for this purpose a, a, is the steam chest sup-
ported upon legs b, b, and provided with a table c, c, to carry the material to be
camped, d, d, is the steam pipe, e, e, the perforated partition or plate, and f.f, the
narrow opening in the side of the chest through which, the operative passes a rod
to spread the material backwards and forwards over the perforated plate e, c, g, 9, 1s
the narrow slit in the top of the chest through which the material passes into the
chest, and h, h, is a dooi at one end for removing the same, 2, 2, are the fluted
crimping rollers, and k, h, are the guide rollers, one of the fluted 1olleis being
driven by means of a strap passing round a pulley 1, 1
When it is desired to crimp the material it is passed over the guide rollers k, k,
and between the two (or more) fluted rollers 2, t, where it becomes cumped, and
thence through the uniow opening or shit g, g, on the top of and into the stean
chest a, a, it is then spread backwards and forwards by the operative with a rod
through a nanow opening f, f, in the side thereof until it becomes saturated with
the steam, it is then removed through the door h, h, at the end of the chest, and
allowed to dry without being stretched until it is "set" By this arrangement the
fabic is regularly and evenly camped throughout the whole length of the piece,
which gives it a much better appearance and enhances its value to a very great
extent.
Having now described the nature and object of our said Invention, together
with the manner in which the same is to be or may be performed on carried into
practical effect, we wish it to be understood that we claim as our Invention,-
Crimping fabrics by passing them first through a pair of fluted rollers and thence
immediately into a steam chest to "set" the crimps or flutes
And, Secondly. We claim the general arrangement and construction of apparatus,

page_text: substantially as herein-before described and illustrated by the annexed Diawing
for effecting this object
In witness whereof, I, the said Peter Buy (on behalf of myself and the said
James Dyson), have hereunto set my hand and seal, this Twenty-fourth
day of July, in the year of our Loid One thousand eight hundred and
seventy-seven.
