PROVISIONAL SPECIFICATION.
Improvements in Ink Pads for Rubber Stamps.
I, JOHN THOMAS CLARKE, of Faulkner Street, Manchester, in the County of
Lancaster, Rubber Stamp Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention is designed to provide a pad for inking rubber stamps which will
be more serviceable and economical than many of those at present in use.
It consists essentially in making the pad reversible so that when one side becomes
dry the other can be used, or so that two colours of ink may be used with the
same pad.
In carrying out the invention I construct the pad preferably with a wooden base
or centre and two faces each saturated with ink. The wooden base is covered ou
both sides with two or more layers of cloth each saturated with ink or provided
with gelatine or similar material beneath the cloth, or I make the two pads
separately each with a wooden back and glue the two together. This method has
the advantage that the edges of the cloth are secured between the two backs or
centres of wood.
The two faces of the pad may be saturated with the same ink or with different
colours of ink as may be required.
The pad is fitted loosely into a metal box provided with a hinged lid which
protects the pad from dust and dirt and prevents the evaporation and drying up of
the ink.
Where the two faces of the pad are inked with the same ink when one side
becomes dry the other can be turned up and is ready for use and where two colours
of ink are used either side of the pad can be turned up and used in this case both
the top and bottom is made with a bead or rim against which the pad will rest so
that the ink will not lodge on the box and the ink from one side of the pad will not
discolour that on the other.

COMPLETE SPECIFICATION.
Improvements in Ink Pads for Rubber Stamps.
I, JOHN THOMAS CLARKE of Faulkner Street, Manchester, in the County of
Lancaster, Rubber Stamp Manufacturer, 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 is designed to provide a pad for inking rubber stamps which will
be more serviceable and economical than many of those at present in use.
It consists essentially in making the pad reversible so that when one side
becomes dry the other can be used, or so that two colours of ink may be used with
the same pad.
It will be fully described with reference to the accompanying drawings.

page_text: faces or sides saturated with ink either of the same or different colours. I at
present make the pad by placing on the wood (which may be varnished on one side
to prevent it absorbing the ink) one, two or more pieces of cloth, felt or other
suitable material B and covering the same with calico or other cloth or fabric C.
This covering is wrapt tightly over the edges and fastened with glue on the back
of the wood. Two of these pads are glued or cemented together back to back the
grain of the wood in one piece is preferably placed across that of the other to
prevent warping or the pad becoming hollow in the centre. This method has the
further advantage that the edges of the cover are secured between the two wooden
blocks.
Instead of two wooden blocks placed back to back a single wooden block may be
employed with pieces of cloth at both sides covered to form two faces to the pad.
The two faces of the pad may be saturated with the same ink or with different
colours of ink as may be required.
The ink is preferably prepared from aniline dissolved in water and methylated
spirits and mixed with glycerine or other suitable substitute to the desired con-
sistency and may be of any required colour.
The pad is fitted loosely into a metal box D provided with a hinged lid which
protects the pad from dust and dirt and prevents the evaporation and drying up of
the ink. And at one end it is provided with a ring or knob d fitting into a slot in
the side of the box by which it can be lifted out of the box.
Where the two faces of the pad are inked with the same ink or ink of the same
colour when one side becomes dry after considerable usage the pad is turned over
in the box when a fresh surface or pad presents itself ready for use.
Where two colours of ink are used and each face of the pad is of a different
colour the pad can be turned over at will to present either side for use.
In this latter case a loose tray d' may be fitted into the bottom of the box D to
prevent the inks of different colours coming in contact with each other one face of
the pad when turned down would be allowed to rest upon the bottom of the box
and the other face when turned down would rest upon the tray d¹. Or if preferred
the bottom of the box and also the lid may be made with a bead or rim against
which the pad can rest so that the ink may not lodge on the box and so prevent
the ink on one face discolouring that on the other.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A pad for inking rubber stamps constructed with two faces saturated with
inks of the same or different colours so that when one becomes dry the other can be
used or that one pad can be employed for providing two different inks substantially
as described.
2. In an inking pad the combination of a wooden base or centre covered on two
sides to form two inking surfaces, a box or case to contain same
provided with a
slot in the end, a ring or its equivalent to serve as a handle, and a loose tray to
prevent the inks discolouring one another substantially as described.
