'Improvements in Colour Pads and Machines for Stamping Marks
upon Textile Materials.
I, ROUGHSEDGE WALLWORK, of the Firm of Henry Wallwork and Company,
of Union Bridge Iron Works, Rogers Street, Manchester, in the County of
Lancaster, Engineers and Ironfounders, do hereby declare the nature of this
invention to be as follows:-
My improvements relate to colour pads and consists in so arranging this pad in
one, or, several sections so that one, or more colours may be stamped at one time,
and, also arranging that the amount of colour distributed upon the pad, or, any
section of same can be regulated according, to the nature of the stamp that is to
be used, or, material to be stamped.
In one modification I arrange two bars carried upon runners, the bars being
the width of the machine, or, hand pad, between these bars is a space say one
eighth of an inch, so that lose distributing plates of the necessary width are
placed at right angles to the pad, these plates at the bottom edge are covered with
a flexible material that comes in contact with pad and travel backwards and
forwards over the pad, at the end of each stroke these plates are lifted to allow the
colour to pass under to be drawn across the pad to the other side, when the action
is reversed, according to the amount of colour required more, or, less pressure is
applied to these distributing plates, by means of weights, springs, or, screws.
If several colours are required to be stamped at the same time the bottom pad is
arranged with divisions, or, in seperate sections with the corresponding distribut-
ing plates.

Improvements in Colour Pads and Machines for Stamping Marks
upon Textile Materials.
I, ROUGHSEDGE WALLWORK, of the Firm of Henry Wallwork and Company,
of Union Bridge Iron Works, Roger Street, Manchester, in the County of
Lancaster, Engineers and Ironfounders, 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:
My improvements relate to colour pads, and consist in so arranging this pad
in one or several sections, so that one or more colours may be stamped at one

page_text: T
time, and also arranging that the amount of colour distributed upon the pad, or
any section of same, can be regulated according to the nature of the stamp that
is to be used, or material to be stamped.
In one modification I arrange two bars carried upon runners, the bars being
the width of the machine or hand pad; between these bars is a space, say one
eighth of an inch, so that loose distributing plates of the necessary width are
placed at right angles to the pad, these plates at the bottom edge are covered with
a flexible or other suitable material that comes in contact with pad, and travel
backwards and forwards over the pad, at the end of each stroke these plates are
lifted to allow the colour to pass under to be drawn across the pad to the other
side, when the action is reversed. According to the amount of colour required,
more or less pressure is applied to these distributing plates by means of weights,
springs or screws. If several colours are required to be stamped at the same time,
the bottom pad is arranged with divisions, or in separate sections with the cor-
responding distributing plates.
My improvements will be explained in their application to and combination
with that mechanism for stamping or printing trade and other marks or matter
upon piece goods, also applicable for other purposes-the subject of Letters
Patent granted to me numbered 15185 and dated the 23rd day of August 1892,
and will be illustrated by the figures upon the accompanying two sheets of draw-
ings, of which

In Figs. 1 and 2, a, represents part of the table of the machine illustrated by

page_text: Figs. 1, 2 and 3 of the Complete Specification of the said Letters Patent granted
to me, upon which table the piece goods are placed to be printed upon, the eleva-
tion of this table being adjusted as described in the said specification by screws a¹,
and hand wheels a².
b, represents the bar or beam extending across the machine to the underside of
which the printing blocks, plates or surfaces are attached as described in the said
specification.
The ends of this bar or beam b, are arranged in horizontal guides, and the bar
or beam is moved to and fro to bring it to the position shown in Fig. 1, when the
impression is to be made upon the goods placed upon the table a, and to a position
over the inking or color pad which is brought up against the printing surfaces
of the 'blocks secured to the bar or beam. These movements are imparted as
described in the said specification.
c, represents the table, described in the said specification, which carries and to
which the trays for the inking or colour pads are secured, and this table or
frame c, is also adjusted in its elevation to cause the pad or pads to come with
more or less pressure against the printing surfaces applied to the said beam or
bar b, by screws c¹, and hand wheels c², as described in the said specification.
When several different colours or different characters of printing are required
in the same width of piece, the trays c³, are divided into corresponding sections
of the width required with division plates ct, between each section to keep the
colors or inks apart.
Some printing surfaces may require not only different colours but more or
some a less body of colour or ink.
The ink or colour is applied to each section or pad by hand and is not placed
into a trough as described in the said specification, into which trough, the dis-
tributing brush is dipped at each double stroke to a greater or less extent, but
according to my present invention the ink or colour is applied by hand when and
according to the judgment of the attendant a fresh supply is required, and it may
be more or less of a pasty character and not necessarily of a liquid character and so
much is supplied to the pad to last for some time, as that colour or ink in excess
of what is required on that surface of the pad against which the printing surfaces
to be inked come, is kept at each end of the pad, and is brought there at the end
of the stroke of the distributing surface or plate. The surface forming the pad is
varied according to the character of the printing surface of the stamp. For fine
printing surfaces such as are known as zinco stamps, india-rubber is used or any
other suitable material with a smooth and elastic surface.
For copper faced stamps I prefer to use loose coverings of felt upon a rubber
pad, which coverings can be readily changed using the same rubber pad for different
colours. These loose covers are attached to metal plates at the ends, and have
hooks (see Fig. 3) or holes at one end to hook or pass onto studs at the edge of
the tray, forming the bed of the pad, and at the other end the metal strips have
screw nuts for screws c6, to screw into, which screws have thumb or wing screw heads
and the stems of the screws pass through holes in projections from the vertical
edge of the trays, so that by these thumb screws the pad surfaces may be stretched
to and held at the proper tightness (see Figs. 3 and 4).
A separate pad surface is or may be used for each colour or ink or stamp, and
When the ink or colour is put upon the
one may be readily changed for another.
surface of the pad, the distributing plates hereinafter more particularly described,
act to distribute it and make it even and to drive all excess of color or ink before
it to one end of the pad leaving that surface of the pad which is to come against
the printing surface evenly spread with ink or colour and of the required thickness
to suit the printing surface, and then the distributing plate lifts over the excess
of colour or ink which it has driven to one end of the pad, and on the return stroke
of the distributing plate drives it before it in like manner to the other end of
the pad and so on at each to and fro stroke. When the attendant sees that the
excess of colour or ink is becoming exhausted he adds more upon the pad.

page_text: - According to the modification shown by. Figs. 1 and 2, and by Figs. 12, 13
and 14 there are two bars d, which extend across the machine, with a space
between them to the extent of the thickness of the distributing plates, and a little
more to allow free vertical movement to the distributing plates. These-double
bars d, are connected. together at the end and secured to a part having a pivot
upon it for a pulley or roller 7, one at each end of the double bars d.
These bars d, are secured at each end to one end of a connecting rodd, which
is jointed to the bar or beam b, for the printing blocks stamps or surfaces.
One of these connecting rods .d², is only shown in Fig...1.
L
By these connecting rods, the double; bars d, are moved to and fro with the
beam or bar. b, for the printing surfaces..
In Figs. 1 and 2--the beam or bar b, and double bars d, are shown in the posi-
tion they occupy when the impression is being made. The pulleys-d', at each
end of the double bars-rest on a surface. which forms a slide d³, grooved on its
underside and slides to and fro on a bar c', or slideway carried on the side frame
of the table e, one only of which- on one side is shown in Fig. 1, and it is also
shown in Figs. 12, 13 and 14..
5.
The upper surface of the slide d³, has two hollows in it which may correspond
to the curve of the pulleys d¹, which rests in one of them nearest the bar or
beam b, when in the printing position as shown in Figs. 1 and 2, in which position
the lower edge of the distributing plate has been lifted over the excess of ink or
colour on the pad, to the outside of it, and when the double bars, d, are moved to
the other end of the pad, the slides d³, move with them until one of their ends
comes against stops (8) at the end of the pad, (these stops are on the bar c)-the
movement of the slide d³, being thus arrested while the double bars d, continue
their movement for a time, the rollers d¹, have then to mount out of the hollow
they are in in the upper surfaces of the slides d³, and this lifts the lower edges of
the distributing plates over the excess of colour or ink driven in front of them,
and they pass over it and then drop again when the rollers d', at the ends of the
double bars drop into the other hollows in the upper surfaces of the slides d³, so
that when the double bars make their back stroke the distributing plates drive
the excess of colour or ink before them until the other end of the. slide comes
against the stop at the other end of the pad tray when the rollers again mount and
pass the lower edges of the distributing plates over the excess of ink or colour and
then drop into the other hollows in the surfaces of the slides d³, and so on for each
to and fro movement.
The distributing plates e, shown in Figs. 1 and 2, and also in Figs. 12, 13
and 14 are made with any desired rubbing or distributing edge and they .are
guided vertically in the spaces between the double bars d, so as to be free to rise
and fall. They are weighted to the required extent to give the lower edge the
desired pressure upon the surface of the pad. by weights e, which may be secured
to their upper ends by set screws. e², these weights being formed with a slit to
pass upon the upper end of the distributing plate e, and the set screw. screwing
through a tapped hole in the weight, its end coming. against the side of the dis-
tributing plate.
Between the lower edge of the weight e¹, and the upper edge of the double
bars d, there is a small space left, sufficient to allow the weights to keep the
lower edge of the distributing plate against the pad, but not so much space to
allow the lower edge of the distributing plate e, to descend when the double bars
are lifted; so as to touch and not pass clearly over the surface of the excess of
colour or .ink.on the pad. Figs. 3 and 4 and on a larger scale Figs. 5, 6 and 7
and also Figs. 8 and 9, illustrate another mode of arranging the distributing
plates.
Instead of two bars d, as shown in Figs. 1 and 2, and Figs. 12, 13 and 14, there
is one bar d, which acts not only to carry the distributing plates e, but also as a
means of putting the desired weight or downward pressure upon them to keep
them against the surface of the pad.

page_text: The one weight bar d, is arranged in every respect the same as the double
bars d, except as hereinafter explained. In front of the weight bar d, there is
a dovetail groove ³, formed from end to end to which groove any desired number
of attachments may be secured, one for each distributing plate required or for
each two distributing plates.
These attachments de, have a dove-tailed projection d, from them that enters
and fits into the dove-tailed slot in the weight bar, and they are secured in any
desired position in the dove-tail slot by a set screws, which screws through
them, the end of which screw comes against the bottom of the dove-tail groove
and thus binds the dove-tail part of the attachment firmly to the weight bar d.
Each attachment do, has two screws, screwing into its upper edge, each screw
with a disc below its head that enters a notch e³, in one edge of the distributing
plate e, one screw may act upon the edge of one distributing plate and the other
screw upon the edge of the adjoining plate e, (see Figs. 5, 6 and 7).
By these screws, the downward pressure of the lower edge of the distributing
plate upon the surface of the pad may be adjusted..
Fig. 15, illustrates another mode of securing the distributing plates to the
weight bar, formed as described in reference to Figs. 3 and 4, 5, 6 and 7.
There is a dove-tailed part da, to fit the dove-tail slot in the weight bar dt.
This dove-tailed part has a screw from it for a winged screw nut db.
The distributing plates e, for this modification are made with slots e', as shown
in Figs. 17, 18, 19 and 20.
The screw from the dove-tailed part da, is passed through the slot, in the
distributing plate and then is secured by the winged screw db, as shown in Fig. 15,
being first pressed downwards to give the lower edge of the distributing plate
the required pressure upon the surface of the pad.
The lower or operating edges of the distributing plates e, are made variously
according to the quantity of ink or color to be left upon the surface of the
pad which is to come against the printing surfaces which will vary according to
the character of such surfaces whether they are to have much or little ink or
colour applied to them.
The operating edges in some cases are made of india rubber or felt e, secured
to the lower edge of the distributing plates as shown best in Figs. 8 and 9.
In some cases a metallic or other suitable edge of solid material e, is used,
secured as shown best in Figs. 10 and 11 and Figs. 17 and 18, while for printing
surfaces requiring much ink or colour the lower edge of the distributing plates e,
require a brush or bristles e, secured to them as shown best by Figs. 19 and 20.
In place of the slide d³, upon which the rollers, at the ends of the double
bars d, or the weight bar work, the ends of these bars have or may have round
projections do, one at each end, these projections de, sliding upon the upper
surface of the slideway e, formed with a shunt tongue de, jointed at one end to a
projection above the slideway at d.
When this round projection do, arrives at the free end of the shunt tongue do,
it passes up it and over its joint part d', and then drops, so that when moved
back it passes under the shunt tongue do, and lifts it, which falls when it has
passed. There is a similar arrangement of shunt tongue at both ends of the
pad, to lift the lower edges of the distributing plates over the excess of colour
or ink.
Or the pulleys d', may be lifted at each end of the stroke by a rotary
cam.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what.
I claim is: -
1. The distribution of ink or colour upon pads by the edges of plates or their
equivalents which push all surplus ink or colour before them over the pad to
one end of it, and then lift to pass clear over the excess of colour so pushed before
them, pushing such colour or ink to the other end of the pad on the return stroko

page_text: and then passing over it in like manner and so on for each stroke leaving the
required quantity of colour on that part of the pad against which the printing
surface has to come to be inked or coloured substantially as and for the purpose
herein before described.
2. The combination of the bar or bars carrying the distributing plates or their
equivalents with the bar or beam carrying the printing blocks, plates or surfaces
so that one gives movement to the other substantially as and for the purpose
herein before described and illustrated by Figs. 1 and 2, and 3 and 4 of the
drawings.
3. The combinations of mechanism for actuating the bar or bars carrying the
distributing plates or their equivalents, and means for lifting them over the excess
of ink or colour on the pad substantially as hereinbefore described and illustrated
by Figs. 1 and 2, Figs. 3 and 4 and Figs. 12, 13 and 14 of the drawings, or sub-
stantially as herein before described and illustrated by Fig. 16 of the drawings or
any equivalent arrangement for the same purpose.
4. The mode of actuating, holding and pressing the lower edges of the dis-
tributing plate or plates upon the surface of the pad or pads substantially as
herein before described and illustrated by Figs. 1 and 2, Figs. 12, 13 and 14 and
by Figs. 3 and 4, Figs. 5, 6 and 7 and by Fig. 15 of the drawings.
5. The mode of constructing the colour or ink pads with loose coverings that
can be changed to suit the various stamps and various colours, and stretching and
holding the same on the pad substantially as herein before described and illus-
trated by the drawings..
6. The mode of constructing the distributing plates or their equivalents with
the required operating edges substantially as hereinbefore described and illus-
trated by the drawings.
7. The combination and arrangement of mechanism substantially as and for
the purpose hereinbefore described and illustrated by Figs. 1, 2, 12, 13 and 14,
and by Figs. 3, 4, 5, 6 and 7 and by Fig. 15 of the drawings.
