Year: 1885

page_text: We EDWARD WEILD of 7 Weymouth Street Chorlton upon Medlock, Manchester,
Engineer and HENRY RICKARDS of 2 Ash Bank, Northenden, in the County of
Chester, Velvet Manufacturer, do hereby declare the nature of our invention of
"IMPROVEMENTS IN AND MACHINERY FOR COLOURING THE EDGES OR SELVIDGES
AND FOR IMPARTING STRIPES OF COLOUR TO VELVET AND OTHER FABRICS," to be
as follows:-
The object of this invention is to apply a stripe or stripes of colouring to the
surface or to the edges or selvidges or to colour the whole edges or selvidges of
velvets and other fabrics whereby to ornament or improve the general appearance
of such fabrics and consists in passing the piece of fabric first under and over a
series of rollers having adjustable flanges whereby such fabric is straightened and
all creases removed, after then passing between a pair of pressure rollers, the
fabric follows an endless blanket beneath a guide roller, and then leaving such
blanket it passes upwards again and over an angular slide, provided with adjustable
side guides or swords for keeping the selvidges in proper position and to still
further straighten the fabric. The fabric now again joins the blanket and passes
with each of its edges beneath a circular brush, (hereinafter called the colour
brush), revolving over a contact roller made of iron or wood and by preference
covered with india-rubber or other suitable yeilding material.
This colour brush forms an essential feature in our invention and consists of a
circular brush on each side of which is a metallic plate or disc capable of revolving
freely upon the boss of the brush so that as the fabric passes beneath, these plates
are caused to revolve in one direction by contact with the material whilst the
brush itself is speeded up by gearing to run at an accelerated speed in the contrary
direction and thus to ensure a proper body of colour being imparted to form the
stripe of the exact width of the space between the plates; and which colour is
received by the brush running in contact with a disc wheel, which in its turn
receives its supply from another roller, running in a trough containing such
colouring matter.

page_text: In this manner continuous stripes or whole edges of colouring matter are
imparted to the surface or to the edges or selvidges of the fabric as it passes
beneath the said colour brushes, and in order to effectually dry and fasten the
coloured stripes or edges so produced, the fabric is then passed round a calendering
roller or steam heated cylinder before being received upon the beam.-By having
the revolving brushes adjustable upon their axes, say by right and left hand screws,
it will be readily apparent that the width between the stripes can be altered and
also to suit any width of fabric, and the contact roller is also adjustable in height
so as to press more or less against the brushes, or may be mounted in a swinging
frame weighted to the desired pressure.
The colouring matter employed may be any desired pigment, mixed with analine,
or mixed to the desired consistency and body with turpentine, glue, paste, or other
similar material or bronze, gold, silver, platinum, copper, tin or other metal either
mixed with gum or other suitable adhesive substance or applied separately.
We, EDWARD WEILD of 7 Weymouth Street, Chorlton-upon-Medlock, Manchester,
Engineer, and HENRY RICKARDS of 2 Ash Bank, Northenden in the County of
Chester, Velvet Manufacturer, do hereby declare the nature of our invention of
"IMPROVEMENTS IN AND MACHINERY FOR COLOURING THE EDGES OR SELVAGES
AND FOR IMPARTING STRIPES OF COLOUR TO VELVET AND OTHER FABRICS," and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
The object of this invention is to apply a stripe or stripes of colouring to the
surface or to the edges or selvages or to colour the whole edges or selvages of
velvets and other fabrics, whereby to ornament or improve the general appearance
of such fabrics and by improved machinery as hereinafter described.
On the accompanying drawing Fig. 1 is a front view Fig. 2 a side view Fig. 3 a
back view Fig. 4 a side sectional view and Fig. 5 a plan of our improved machine.
Fig. 6 is a side sectional view (upon an enlarged scale) of the angular slide and
adjustable side guides or swords and taken through the centre of the colour box.

and stencil plates in section Fig. 10 is a cross section of the paying on wheel
shewing also the doctor plate. Fig. 11 is a cross section through the centre of
the picking up colour roller in Fig. C.
In performing our invention we pass the piece of fabric a first under and over a
series of rollers bbb having adjustable flanges c c c whereby such fabric is
straightened and all creases removed after then passing between a pair of pressure
rollers & the fabric follows an endless blanket e (see Figs. 4 and 6) which passes
beneath a guide or stretching roller f whilst the fabric itself leaves such blanket
and passes upwards over an angular slide g provided with adjustable side guides or
swords has seen more clearly in plan view Fig. 12 for keeping the selvages in
proper position and to still further straighten the fabric. These slides gare
mounted upon the right and left handed screws gl and thus are capable by turning
the hand wheel gå of approaching towards or receding from each other. The fabric
now again joins the blanket and passes with each of its edges beneath a circular
brush (hereinafter called the colour brush) revolving over a contact roller j made
of iron or wood and by preference covered with india-rubber or other suitable
yeilding material. This contact roller j is adjustable in height so as to press more
or less against the revolving brushes by being mounted in a swinging frame 1
weighted by the weights 2 to the desired pressure. The revolving colour brush i
forms an essential feature in our invention and consists of a circular brush i (see
Figs. 6, 8 and 9) on each side of which is a metallic plate or disc k. capable of
revolving freely upon the boss or axis of such brush so that as the fabric passes
beneath these plates / which act as annular stencil plates they are caused to revolve
in one direction by contact with the fabric whilst the brush itself is speeded up by
gearing to run at an accellerated speed beyond that of the fabric either in the same
or in the contrary direction and thus to ensure a proper body of colour being
imparted to form the stripe of the exact width of the space between the plates /
and which colour is received by the brush running in contact with a disc or paying
on wheel m provided with an adjustable docter plate m³. This wheel m in its
turn receives its supply of colour from another or picking up roller n running in a
trough o containing such colouring matter.
The colouring matter employed (which forms no part of the present invention)
may be any desired pigment mixed with analine or mixed to the desired consistency
and body with turpentine, glue, paste or other similar material or bronze, gold,
silver, platinum, copper, tin or other metal either mixed with gum or other suitable
adhesive substance or applied separately.
The gearing for revolving the color brush at an accellerated speed is seen in
Figs. 7 and 8. It consists of a spur wheel r gearing through the intermediate
pinions with the axis of the color-brush-the spur wheel r being mounted upon
one extremity of the roller axis m² whilst the spur wheel s upon the other
extremity is geared into the sliding spur wheel m' upon the slotted driving shaft n³
which receives its motion from the strap pulley u. It will be observed froin
reference to Figs. 3 and 5 that each color box o is driven independently by means
of a clutch box t and its own separate driving pulley u. The color boxes o are
each mounted upon V slides and are adjustable to the greatest nicety by means of
right and left hand screws w actuated by hand wheel as seen in Figs. 3 and 5.
By thus having the color boxes and revolving brushes adjustable upon their axes
and in distance from each other it will be readily apparent that the width between
the stripes can be altered and also to suit any width of fabric.
In this manner continuous stripes or whole edges of coloring matter are imparted
to the surface or to the edges or selvages of the fabric as it passes beneath the said
color brushes and in order to effectually dry and fasten the colored stripes or edges
so produced the fabric is then passed round a calendering roller or rollers or gas or
steam heated cylinders p before being received upon the beam q. After the fabric
has been so selvaged and dried the edge can be burnished embossed or crimped and

page_text: for which purpose the brushing arrangement can be removed and be substituted by
a plain, embossed, engraved or corrugated roller made of any suitable material to
effect the desired object.
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 as our "Improvements in and machinery for coloring the edges or
selvages and to impart stripes of color to velvet and other fabrics," is
1st The improved method of coloring the edges or selvages of velvets and other
fabrics and of imparting stripes of coloring thereto substantially as herein before
