We, JASPER, SMITH, of Abbey Street, Bethnal Green, in the County of
Middlesex, Chenille Manufacturer, and THOMAS TAYLOR, of Wellington Row,
Bethnal Green, in the County of Middlesex, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN THE MANUFACTURE OF CHENILLE,
AND IN MACHINERY FOR THAT PURPOSE," to be as follows:-
Our Invention consists in the use of an endless band or core of metal, or
other suitable material, which passes over pulleys driven at the required speed
in any
convenient manner, and through a hollow spindle revolving in fixed
bearings, upon which spindle is mounted a disc, which carries bobbins con-
taining the material for making the pile of the chenille. One end of the
material for forming the inner body, upon which, in conjunction with an outer
body, the material for forming the pile is to be spun, is passed together with
the endless band or core through the hollow spindle. This body lies in a
groove in a fixed mandril, upon which the hollow spindle revolves. This
mandril also serves as a guide for the endless band or core, or the guide may
be detached. The material of which the pile is to be formed is then lapped
or wound round the endless band or core, and the material forming the inner
"body" by means of the revolving disc, as is well understood. The endless
band or core, thus covered, passes on through a guide, which conducts the

page_text: material for forming the outer body into its place. This endless covered
band or core with its inner and outer body now comes in contact with either
fixed, revolving, or reciprocating cutting edges, which cut the material for
forming the pile. The end of the material thus cut, together with the two
bodies, are then connected to a suitable spinning apparatus, which twists it
into chenille. The core may be of elliptical form, or flat, or of square or
triangular, or any suitable form, and it may or may not be grooved, and it
may be arranged with one, two, or more sets of bobbins and cutters, and
spinning apparatus, so as to produce one, two, or more pieces of chenille at
the same time. The cutting edges may also be formed on the band or core
itself, and may act against other fixed or revolving surfaces. In some cases
we divide the core into two pieces, keeping them apart at the place where the
pile material is being wound on by means of a fixed mandril, and introducing
a reciprocating or revolving cutter or cutters beyond the mandril, and between
the two parts of the core to cut the pile. Or we keep the two parts of the
core in contact while being covered with the pile material, and allow the cutters
to enter between their edges, or to penetrate between them when the pile is
being cut. This arrangement may be advantageously applied to the flat and
elliptical forms of band or core. Thus two thin flat bands, or bands having
one side flat and the other slightly convex may be used with their flat sides
placed together. The flat bands and the slightly convex and elliptical bands
may also be used as stationary bands or cores, being fixed at each end while
the other machinery is caused to travel along them; but we consider the
endless band or core to be preferable. To make an ordinary uniform chenille,
the band is made parallel, but we sometimes make the band with undulations,
or of varying width or thickness, in which case the chenille will have corre-
sponding enlargements and contractions. The cutting apparatus is made to
accommodate or follow the depressions and projections.
