PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Adhesive Letters, Numbers,
Signs, Ornaments, and the like.
I, JULES EMILE BENNER, of Charenton in the Department of Seine, in the
Republic of France, Merchant, do hereby declare the nature of this invention to
be as follows
This invention has for its object, a process for the manufacture of letters and
ornaments in celluloid for signs, decorations, and the like, which allows of their
production more cheaply, and of being more easily fixed than is the case with those
now in use.
In the manufacture of the said letters, ornaments and the like according to this
invention moulds or matrices are used of any shape, in which are sunk the
impressions of the letters or the like, and over the surface of these moulds or
matrices is applied a sheet of celluloid, the said moulds being submitted to a
suitable temperature according to the surface and thickness of the sheet of celluloid
which is then forced by means of a suitable die under heavy pressure to take the
form of the imprint and afterwards trimmed and polished as desired.
To fix the letters or the like on glass or other surfaces: the interior or hollow
part is coated with a layer of clear varnish mixed with flake white, and is
subsequently filled with white lead prepared with gold-size and then applied on the
surface.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Adhesive Letters, Numbers,
Signs, Ornaments, and the like.
I, JULES EMILE BENNER of Charenton in the Department of Seine, in the
Republic of France, Merchant, 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 has for its object a process for the manufacture of letters and
ornaments in celluloid for signs, decorations, and the like, which allows of their
production more cheaply and of being more easily fixed than is the case with those
now in use.
In order to more clearly explain the manufacture of these letters we have shown
on the annexed drawing by
Figure 1, a section through A-B, Figure 2, of the matrix and die (male and
female side of matrix).
Figure 2 a plan of the matrix.
Figure 3 a plate having been stamped in the matrix, cut, and filled with white
lead.
Figure 4 a view of same forming the letter O.
As shown by Figure 1, to obtain letters or ornaments, a sheet of celluloid X of
the desired thickness is laid on the lower part D of the matrix which is then
subjected to a suitable temperature and the die C is applied with great pressure on
the celluloid to force it into the shape of the mould D.

page_text: This stamping having been effected the letter is cut by any suitable means to
remove the surplus material and the outside is polished.
This result being obtained the inside is coated with a layer of flake white thinned
with varnish, thus giving great adhesive power to the white lead which is run into
the hollow cavity of the letter in sufficient quantity to fill it. If the reverse of the
letter is visible as in a shop window I add gold or silver powder to the white lead.
The letter being filled it is applied to the required position and the excess of
white lead is removed.
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. The process of manufacturing letters or ornaments in celluloid of any shape or
dimension substantially as described.
2. The method of fixing the letters or ornaments thus obtained on glass or other
surfaces for their reception, this method giving a perfect and durable adhesion
substantially as described.
