PROVISIONAL SPECIFICATION.
Improvements in and relating to the Mounting of Photographs and
other Pictures.
I SHERIDAN DELÉPINE M.B. B.S. Professor of Pathology at Owens College,
Manchester in the County of Lancashire, do hereby declare the nature of this
invention to be as follows:-
It has hitherto been found difficult to properly mount photographs and other
pictures on account of the presence of air bubbles and through the picture not
thoroughly adhering to the mount all round the edges.
My invention consists in coating the material used for the mount with a thin
layer or layers of a solution of gelatine or other allied substance or substances
having the same property for this purpose. I then allow the prepared surface to
dry thus rendering this surface insoluble in cold water so that when this prepared
surface is again wetted with cold water and the photograph or other picture (also
wetted) is applied against this prepared surface, perfect adhesion will result when
the surface is again dry.
Instead of preparing the mount as above stated I may prepare the back of the
picture.

Improvements in and relating to the Mounting of Photographs and
other Pictures.
I SHERIDAN DELÉPINE M.B.Mch., B.S.C., Professor of Pathology at
Owens College, Manchester in the County of Lancashire 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:-
It has hitherto been found difficult to properly mount photographs and other
pictures on account of the presence of air bubbles and through the picture not
thoroughly adhering to the mount all round the edges.
My invention consists in coating the material used for the mount with a thin
layer or layers of a solution of gelatine or other allied substance or substances
having the same property for this purpose. I then allow the prepared surface to
dry thus rendering it insoluble in cold water so that when this surface is again
wetted with cold water it swells without dissolving, and when the photograph or
other picture (also wetted) is applied against this prepared surface perfect adhesion
will result when dry.

page_text: Instead of preparing the mount as above stated I may prepare the back of the
picture.
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. Improvements in and relating to the mounting of photographs and other
pictures substantially as set forth.
2. In the mounting of photographs and other pictures, coating the material used
for the mount or the back of the picture or photograph itself with a layer or layers
of a solution of gelatine or other allied substance or substances having the same
property for this purpose, for the purpose set forth.
