PROVISIONAL SPECIFICATION.
Improvements in or relating to Sign Letters.
I, GEORGE JAMES BELLAMY RODWELL of Buffalo, New York State, United
States of America, Manufacturer, do hereby declare the nature of this invention to
be as follows:-
This invention relates to sign letters and the fixing of such letters to the
supporting surface. Usually these letters are made of metal or earthenware and
the difficulty in fixing them is that they do not expand to the same extent
or in the same manner as the surface upon which they are fixed. This surface is
usually glass as a window or sign backing and the object of this invention is to
enable letters to be securely fixed especially to a sheet of glass without danger of
their being broken or falling off.
In carrying out this invention I place upon the back of the letter a piece of
material which will adhere to both the letter and the surface to which it is to be
attached, but not being of a rigid nature will accommodate the different expansion
and contraction of the letter and the plate. Probably the best material for this
purpose is india-rubber but other suitable textile or similar fabric or material may
be employed and cemented or otherwise securely fastened to both the letter and the
supporting surface. In the case of rubber it may be vulcanized on instead of being
cemented.
Dated this 27th day of October 1890.

1, GEORGE JAMES BELLAMY RODWELL, of Buffalo, New York State, United

and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following Specification
:-
This invention relates to sign letters and the fixing of such letters to the supporting
surface. Usually these letters are made of metal or earthenware and the difficulty
in fixing them is that they do not expand to the same extent or in the same manner
as the surface upon which they are fixed. This surface is usually glass as a window

tion and in what manner the same is to be performed, I declare that what I
claim is
The employment of an intermediate material between the letter and the support
for the purpose of accommodating the unequal expansion and contraction of the two
substantially as described:
