Improvements in Rubber Stamps.
I, TAYLOR SCOTT BUCK, of 58 John Street, in the City of New York,
United States of America, 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 an improved means of supporting the letters, figures and
other characters which are used on rubber stamps, and the object of my invention
is to overcome the inconvenience now existing, caused by the rigid construction of
such stamps, whereby they are not adapted to make an impression upon uneven
surfaces.
This object I attain by forming out of rubber or other suitable material and in a
suitable manner a flexible foundation or base to support the characters. This
foundation is devised with one or a series of compartments or cells which may be of
any suitable configuration. In one form of my invention, which I will describe
herein these compartments or cells are made cube shaped with walls parallel with
each other; and in the use of this foundation the pressure is applied to these walls
end-wise, thereby affording great elasticity as well as enabling the stamp to conform
readily to uneven surfaces. The cells may be covered on one or both their open
sides with a sheet of rubber or other flexible material.
In order that my invention may be better understood and explained in detail I
have hereunto annexed a sheet of drawings on which like letters of reference
indicate similar parts.
Figure 1, is a perspective view showing one form of my invention.
Fig. 2, is a horizontal section of the same, and
Fig. 3, is a section showing the manner in which my improved foundation or base
is used in connection with the stamp handle.
A indicates my improved foundation or base formed as with compartments or
cells a.
This foundation or base is cemented, glued or otherwise secured either
direct to the handle B, or as shown in Fig. 3. In said Fig. 3, is shown a connecting
strip or piece b, of rubber or other suitable material which is cemented or otherwise
caused to adhere by one side to the handle B, and at the other side is properly
secured by cement or otherwise to the foundation. In the drawings I have repre-
sented the cells of the foundation as having a backing & upon one of their open
sides whilst the other side is left open. I prefer to construct the foundation in this
wise, although as before stated the cells may be closed on both sides or open on
both sides. With my preferred form of construction I cement or otherwise secure
the open end of the cells against the under side of the stamp handle B or against
the strip when such strip is used, and the closed side or backing c I cement or
otherwise secure to the back of the strip of rubber of which the letters, figures or
other characters are formed. Of course it is necessary in securing the handle upon
the open ends of the cells to be careful to cover up the cells properly so as to get the
full benefit of the resistance caused by the air inflation of the cells. As a modification
to the above I may form the flexible foundation with backing and letters, figures or
other characters all in one piece, although in practice I have found it more con-
venient to form the foundation and backing in one piece, and the strip carrying the
letters, figures or other characters in a separate piece as described.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
1. The improved foundation or base for rubber stamps consisting of a series of

page_text: compartments or cells of any suitable configuration adapted to receive the pressure
exerted when using the stamp, upon their walls endwise, thereby affording great
flexibility with sufficient strength of resistance.
2. The improved foundation or base for rubber stamps consisting of a series of
compartments or cells of any suitable configuration provided on one side with a
backing, by which backing the foundation is secured to the characters, the open
side of the cells being secured to the stamp handle or to the strip of rubber or
other material mounted upon said handle, substantially as shown and described.
3. The improvements in rubber stamps, substantially as, and for the purposes
herein before set forth, described and illustrated.
