Complete Specification Left, 23rd Mar., 1897-Accepted, 15th May, 1897
1, FREDERICK RUDOLPH VAN HOUTEN, of 33ª Fore Street, in the City of London,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to india-rubber printing stamps and consists in a novel
construction of elastic cushion between the stamp proper and the mount.
According to my invention the elastic cushion is formed with a number of columns
arranged at right angles or thereabouts to the printing surface, the said columns
being at one end attached to an elastic plate or surface to which the die is fixed
whilst at the other end they are cemented to the mount. Or the columns may
be between two elastic surfaces one of which is fixed to the mount whilst the
other carries the die or printing surface.
In some cases the die or printing surface is formed in one with my elastic cushion.
if desired, when great elasticity is required make the columns hollow or
tubular.

Improvements in India-rubber Printing Stamps.
I, FREDERICK RUDOLPH VAN HOUTEN, of 334, Fore Street, in the City of London,
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 :-
My invention relates to india-rubber printing stamps and consists in a novel
construction of elastic cushion between the stamp proper and the mount.
According to my invention the elastic cushion is formed with a number of
columns arranged at right angles or thereabouts to the printing surface, the said
columns being at one end attached to an elastic plate or surface to which the die
is fixed whilst at the other end they, are cemented to the mount.
To enable my invention to be fully understood I will describe it by reference to
the accompanying drawing, in which
Figure 1 is an elevation of a stamp provided with my new elastic cushion; and,
Figure 2 is a view of the said elastic cushion on the side designed to be applied to
the mount:
Figure 3 is a section on the line 3-3 Figure 2; and,
Figure 4 is a view similar to Figure 1 illustrating a modification of my invention.
a, a are the columns forming my novel elastic cushion which columns at one end
are united with an elastic plate or surface b to which the die or printing surface c
is cemented; the columns a, a are represented in the drawing as cemented to the

page_text: usual mount d. In Figures 2 and 3 of the drawings the columns a, a are
represented as being hollow, as hollow columns afford greater elasticity than solid ones;
but, if desired, solid columns may be used.
In some cases the columns instead of being attached at one end only to an elastic
surface b may be carried between two such elastic surfaces, as shewn in Figure 4,
one of which surfaces carries the die c whilst the other is cemented to the mount d.
It will be obvious that instead of cementing the separate printing surface to the
surface b the said surface b may itself be made to form the printing surface.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what
I claim is :-
1. An india-rubber printing stamp having an elastic cushion composed of a number
of columns arranged between the stamp proper and the mount, substantially as
-described.
2. The manufacture and use of india-rubber stamps with elastic cushions,
substantially as hereinbefore described and illustrated in the accompanying drawing.
Dated this 23rd day of March 1897.
