IMPROVEMENTS IN APPARATUS FOR FINISHING THE PILED SURFACE OF WEFT PILED FABRICS, SUCH AS VELVETS, VELVETEENS, CORDS &C
Year: 1885

page_text: We, SAMUEL CRABTREE of Failsworth, Manchester, Dyer &c; and THOMAS
CRABTREE, of Failsworth, Manchester, Dyer &c, do hereby declare the nature of
our invention for "IMPROVEMENTS IN APPARATUS FOR FINISHING THE PILED
SURFACE OF WEFT PILED FABRICS, SUCH AS VELVETS, VELVETEENS, CORDS &C"
to be as follows:-
The improvements relate to the finishing of the piled surface of cotton velvets,
velveteens, patent velvets, plushes; cords, and other weft piled fabrics; that is to
say pile fabrics which have the pile formed by the weft being floated on the
surface thereof, and are afterwards cut. And have for object the forming of a
machine wherein the whole operation of brushing or finishing the piled surface both
longitudinally and laterally is performed at the same time.
To accomplish this and to effect our improvements, we construct a suitable frame
upon which we. mount revolving rollers and roller brushes, over and underneath
which the fabric passes from one end of the machine to the other, and in combi-
nation with travelling brushes attached to endless travelling bands which pass
round pulleys upon shafts at each side of the machine.
The fabric passes over or between the fixed bars or guides at the end of the
machine, and then underneath a circular revolving brush or revolving brushes,
and then underneath two or more emery rollers revolving in opposite directions
to each other.
These revolving brushes and emery rollers operate upon the fabric longitudinally
or lengthwise of the piece. From thence the cloth passes underneath four or more
travelling bands fitted with brushes which act upon and brush the fabric laterally
or across the piece. Each of these alternate bands travel in contrary directions,
(except in the case of cords) thereby crossing and drawing in the pile, and they are
suitably mounted on revolving pulleys or drums and geared up with a cross shaft
or other requisite gearing. They are also capable of being adjusted so as to all
travel in one direction, for finishing cords.

page_text: After leaving the lateral brushes the fabric again passes underneath one or more
revolving roller brushes, thence over an emery or carded roller which draws the
piece through the apparatus and delivers it to the winding on roller or rollers as is
well understood.
Underneath the cloth is a frame having the usual revolving rollers for holding
the fabric up to the brushes, but we so mount this frame that by a screw motion
we are enabled to lift or lower the same in such manner that greater or less pressure
is brought to bear on the cloth operated upon, as may be desired.
Motion may be given to the moving parts in any suitable mechanical manner,
and variations may be made in detail without departing from the peculiar character
of the invention.

We, SAMUEL CRABTREE, of Failsworth, Manchester, Dyer; and THOMAS

OF WEFT PILED FABRICS, SUCH AS VELVETS, VELVETEENS, CORDS, AND THE LIKE,"
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:—

accompanying drawing proceed more fully to describe means employed by us.
DESCRIPTION OF DRAWING,
The figure represents a side view of apparatus arranged in accordance with our
invention.
a, a, shews the main framing, and b, b, the circular revolving brush, underneath
which the fabric passes after it leaves the guides or bars placed in the slots for the
purpose in the framing at a¹, a¹; and the roller a². From thence the fabric passes
underneath the emery or otherwise prepared rollers c, c, which revolve in opposite
directions, by means of the strap d, d. These rollers and brush operate upon the
fabric longitudinally or lengthwise of the piece; but afterwards the cloth passes to
the four travelling bands e, e, fitted with the brushes f. f. which act upon and
brush the cloth across the piece. Each alternate band-except in the case of
finishing cords-travels in a contrary direction, and they are carried by the
pulleys g, g, mounted on the shaft h, h, geared up from the main driver in any
suitable way.
After leaving the lateral brushes the fabric passes underneath the roller brush j,j,
over the emery or card roller k, k, under the roller l, l, over the rollers m, m,
and n, n, whence it is arranged on the stand or floor by the folding or waving
apparatus o, o, as is well understood.:
-
The fabric is held up to the operating rollers and brushes, by revolving
rollers p, p, underneath, and the whole or a portion of these are mounted on the
bar or frame r, r, and rendered adjustible by means of the hand wheel 8, 8, on the
shaft 8, 8, suitably connected by gearing for the purpose.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that
what we claim is :-
The combination of brushes mounted on travelling bands, operating crosswise of
the piece of cloth, with emery or other rollers operating lengthwise of the cloth, in
one machine, for the purpose of finishing the piled surface of weft piled fabrics of
the kind, and in manner substantially as shewn and described.
