on Cut-pile and other Fabrics.
Wo, JAMES WORRALL of Ordsall, Salford, in the County of Lancaster, Dyer, and
JOHN KERSHAW of Hebden Bridge, in the County of York, Manager, do hereby
.declare the nature of this invention to be as follows:-
This invention relates to improvements in the machinery for which we obtained
provisional protection dated 13th December 1887, No. 17,143, and has for its object
not merely the finishing of cords, but also the raising of a nap on fabrics woven with
floated weft threads.
In the machine above referred to, the cloth entered at the side, passed under and
over a diagonal edge bar, and at the crease was submitted to the action of the brush.
It then passed to a second diagonal edge bar, where the brushing operation was
repeated, and the cloth passed thence out at the end of the machine.
We now propose to introduce the cloth, as before, at the side of the machine, pass
it under and over fixed diagonal edge bars to receive the carding, or it may be
the brushing, operation, and when this is effected, to return the cloth, by means of
guide rollers, back to the entrance side of the machine, and deposit it, by means of
a plaiter or folder, near the feet of the attendant, ready to be again passed through the
machine, to undergo a second and similar treatment.
To give an elastic support to the fabric, which is needful when the raising
operation is being carried on, we place below that portion of the fabric which lies
between the two diagonal edge bars, supporting rollers parallel to the bars, say, three
in number, when two card rollers are used, and it is over the portions of the fabric
which lie between these diagonal supporting rollers, that the card rollers are
mounted.
Thus, the fabric will be free to yield to the pressure of the card rollers, and all
liability of damage to the fabric, from the action of the card rollers, will be avoided,
besides which, the liability of the card rollers themselves to injury, by acting against
an unyielding material, will be removed.

page_text: The cloth to be operated upon has a continuous motion through the machine, it
being drawn through by one or more driven card rollers mounted transversely of the
machine, and a rapid rotary motion is given to the raising or operating diagonal card
rollers by means of overhead belting.
We may remark that this modified form of machine is equally applicable for
finishing as for raising, the card rollers being replaced by rotary brushes, which must
be adjusted to bring them up to a resisting support for the fabric to be operated
upon.
Improved Machinery for Obtaining a Cross-over Finish and Raising
on Cut Pile and other Fabrics.
We JAMES WORRALL of Ordsall, Salford, in the County of Lancaster, Dyer, and
JOHN KERSHAW of Hebden Bridge, in the County of York, Manager, 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 to improvements in the machinery for which we obtained
Provisional Protection dated 13th December 1887, No. 17143, and has for its object
not merely the finishing of cords, but also the raising of a nap on fabrics woven with
floated weft threads.
In the machine above referred to, the cloth entered at the side, passed under and
over a diagonal edge bar, and. at the crease was submitted to the action of the
brush, and the cloth passed thence out at the end of the machine.
We now propose to introduce the cloth, as before, at the side of the machine, pass
it under and over fixed diagonal edge bars, to give it an elastic support while it is
submitted to the carding, or it may be the brushing operation, and when this is
effected, to deliver it in a pile by means of a plaiter or folder, ready to be
again passed, if desired, through the machine, to undergo a second and similar
treatment.
The fabric, as it passes between these diagonal supports, receives the action of the
carding rollers, and being thus free to yield to the pressure of the card rollers, all
liability of damage to the fabric, from the action of the card rollers, will be avoided,

by means of overhead belting.
In the accompanying drawings,
Fig. 1 shows in plan view, and
Fig. 2 in end elevation, the finishing and raising machine described in our
Patent of December 13th 1887, No. 17,143 but modified according to our present
invention.
A A' are the side frames of the machine, held together by cross frames, and CC
are light standards mounted on a lateral extension of the frame A, and carrying guido
bars c c c² 3, parallel to the frame A.
To the lateral extension of this side frame, bracket bearings are bolted, to carry a
guide roller D, which is fitted with a friction pulley d, that will retard its tendency to
rotate under the draught of the cloth that is submitted to the action of the
machine.
So far the construction of the parts referred to is practically the same as those
referred to with the same letters of reference in the specification of our said
Patent.
Instead, however, of the one diagonal bar E for presenting the cloth to be operated
upon to the card roller, we now employ two such bars E E', setting them at some
20 inches apart, and at an angle of 45 degrees to the frames A¹. These bars are
tipped or inclined so as to enable the cloth to be stretched from the outer edge of
the one bar to the outer edge of the other, and thereby present an elastic or yielding
surface to a pair of card rollers F F¹, as illustrated at Fig. 3, which is a section taken
in the line 1, 2 of Fig. 1.
The bars E E are secured in place by being screwed to brackets of the side frame,
and the card rollers F F (represented as some inches in diameter) are carried by
bearings adjustable in the short bracket standards G G', which are bolted onto the side
frames.
Each bearing is fitted with a screw which passes up through the head of its
standard to receive a nut 7 cast with mitre teeth.
These nuts bear upon the top of their respective standards, and support the card
roller bearings in their adjusted position.
To provide for the parallel and exact adjustment of the card rollers, the nuts at the
opposite ends of the card roller are put into gear with mitre pinions gl keyed to a
cross shaft g², and supported in bracket bearings of the standards G G.
g is a hand wheel fitted to one end of the shaft g², and serving to impart an axial
motion to that shaft, which, through the mitre gears, will raise or lower the card
roller, to suit the work in hand.
H is a roller for drawing forward the cloth over the diagonal bars F F', whence the
cloth passes over a guide roller situate immediately above the roller H, and up
io a roller I, which delivers it to the ordinary reciprocating folder K.
The cloth to be treated is brought in a pile to the side of the machine, and laid
alternately over and under the guide bars c c¹ c², as shewn in Fig. 2.-It then
passes under the guide roller D to the underside of the diagonal bar E, and being
laid over the edge thereof, it is carried forward to, and laid over the diagonal
bar E-Thence it passes under the drawing roller H,-up to the guide roller h,
and so passes off out of the machine, as already explained.
The axles of the card rollers FF1 and H are severally provided with pulleys,
for receiving driving bands from overhead driving gear, not shewn in the
drawings.
The pulley of the drawing roller H is however loose on its axle, and it com-
municates rotary motion thereto through spur gearing, as described in the above

page_text: mentioned specification, for reducing the driving speed of the roller H to the
requirements of the machine.
The direction of rotation of all the rollers will be the same, and the relative
speeds of the carding rollers, and of the drawing roller, will accord with the speeds
commonly adopted in this class of machinery.
We may remark that this modified form of machine is equally applicable for
finishing as for raising, the card rollers being replaced by rotary brushes, which
must be properly adjusted to their work.
Having now particularly described and ascertained the nature of our invention
and in what manner the same is to be performed, we declare that what we
claim is :-
The combination, in a finishing and raising machine, of the diagonal tension bars
and the cylindrical rotating finishing or raising surfaces, as illustrated in the
accompanying drawings, for the purpose above set forth.
