We JOHN WALKER, and THOMAS GREEN BEAUMONT of Dewsbury Mills Dewsbury,
Yorkshire, Manufacturers do hereby declare the nature of our invention for "IMPROVE-
MENTS IN RAISING GIGS FOR RAISING BLANKETS, RUGS, FLANNEL, AND OTHER WOVEN
FABRICS," to be as follows:-
Our invention has reference to that class of raising gig where the teazles for
operating upon the fabric are placed upon an axis running in bearings attached to the
periphery of a rotary cylinder the axis of the teazles being placed at an angle to the
axis of the rotary cylinder.
In practice it is found that when the teazles are operating upon fabrics containing
cotton, that the said cotton gathers upon and adheres to the teazles soon rendering
them unfit for work.
The object of our invention is to dispense with the teazles and employ instead
thereof wire cards wrapped around a small axle, and placed in bearings upon the
rotary cylinder.
In order to adapt card teeth for the purpose of raising the "nap" on the fabric the
said card teeth must possess as far as possible the peculiar shaped tooth of the teazles,
which tooth is bent in the direction of its stem thereby rendering it well adapted for
the purpose of lifting or raising the "nap" we therefore place the card teeth on the
axle with the bend in a line with the axis whereby it possesses the same advantages as
the teazles.
It will be apparent that if a filleting of ordinary card teeth were wrapped around a
roller that the teeth would be in a radial line from the centre, in which case the points
of the teeth would be wider apart than the base thereof, to prevent this we insert the
card teeth into its foundation spirally or in the "twill" by which means the teeth are
parallel when fixed to the axle or barrel.
In practice we have also found that when we used axles or barrels of equal diameter
throughout their length that the teeth thereon at each end acted upon the fabric before
the teeth in the middle part of the axle; to prevent this we make the axle or barrel
slightly conical at both ends, whereby the whole surface of the teeth strikes the fabric
at once.

and other Woven Fabrics.
We JOHN WALKER and THOMAS GREEN BEAUMONT, of Dewsbury Mills Dewsbury,
Yorkshire, Manufactures 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 :-
Our invention has reference to that class of raising gig where the teazles for
operating upon the fabric are placed upon an axis running in bearings attached to the
periphery of a rotary cylinder, the axis of the teazles being placed at an angle to the
axis of the rotary cylinder.
In practice it is found that when the teazles are operating upon fabrics containing
cotton that the said cotton gathers upon, and adheres to the teazles soon rendering
them unfit for further use. The object of our invention is to dispense with the teazles
and employ instead thereof wire cards wrapped around a small axle and placed in
bearings upon the rotary cylinder such bearings being arranged preferably at an angle
with the axis of the cylinder.
In order to adapt card teeth for the purpose of raising the "nap" on the fabric, the
said card teeth must possess as far as possible the peculiar shaped tooth of the teazles
which tooth is bent in the direction of its stern, thereby rendering it well adapted for
the purpose of lifting or raising the "nap"; we therefore place the card teeth on the
axle with the bend of the teeth in a line with the axis, whereby it possesses the same
advantages as the teazles.
It will be apparent that if a filleting of ordinary card teeth were wrapped around a
roller, that the teeth would be in a radial line from the centre, in which case the points
of the teeth would be wider apart than the base thereof; to prevent this we insert the
card teeth into its foundation spirally or as is technically called in the "twill" by
which means the teeth will be parallel when fixed on an axle or barrel.
In practice we have also found that when we used axles or barrels, of equal diameter
throughout their length, that the teeth thereon at each end acted upon the fabric before
the teeth in the middle part of the axle; to prevent this we make the axle or barrel
slightly conical at both ends whereby the whole surface of the teeth operates upon the
fabric at once.
In order that our Invention may be better understood we herein give reference to
the accompanying sheet of drawings illustrative thereof. In Fig. 1 A represents a
rotary cylinder covered by conical axles or barrels B supported by short spindles a
rotating in bracket b arranged at each end of the barrel and fastened to the periphery
of the cylinder A so that the barrels revolve at an angle to the cylinder A. The conical
barrels B are covered by a narrow band or filleting of card teeth C, each tooth of
which is made as far as possible to reprisent and answer the purpose of the teeth
formed on a teazel. Fig. 2 is elevation of a barrel on a larger scale where it will seen
that the card teeth are made to bend in a line with the axis of the said barrel whereby
they are adapted for and capable of raising the "nap on the fibre as it passes over.

page_text: To prevent the points of the card teeth being wider apart than the root of the teeth,
we insert the teeth in the "foundation" in what is well known in the trade as in the
twill "
50 that when wound around the barrel the teeth are parallel.
Having now particularly described and described and ascertained the nature and
object of our said invention and in what manner the same is to be performed we
declare that what we claim is :-
Firstly. The use of wire card teeth arranged upon an axis and placed in bearings
upon the periphery of a cylinder for raising the nap or pile on woven fabrics
substantially as set forth.
Secondly. The use of wire teeth fixed in the foundation, in what is called the
"twill" and placing such wire card teeth on the axis arranged in bearings upon the
periphery of a cylinder for raising nap, or pile on woven fabrics.
Thirdly. The use of conical rollers in combination with wire card teeth for raising
nap or pile on woven fabrics.
