Year: 1861

page_text: LETTERS PATENT to Thomas Hooman, of No. 490, New Oxford Street, in
the County of Middlesex, Glass Letter Manufacturer, and John
Maliszewski, of the same Place, Photographic Artist, for the Invention
of "IMPROVEMENTS IN PHOTOGRAPHIC PRINTING UPON THE INTERIOR OF ANY
GLASS OR OTHER TRANSPARENT VESSEL."
Sealed the 24th October 1861, and dated the 1st May 1861.
PROVISIONAL SPECIFICATION left by the said Thomas Hooman and
John Maliszewski at the Office of the Commissioners of Patents, with
their Petition, on the 1st May 1861.
We, THOMAS HOOMAN, of No. 490, New Oxford Street, in the County of
Middlesex, Glass Letter Manufacturer, and JOHN MALISZEWSKI, of the same
Place, Photographic Artist, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN PHOTOGRAPHIC PRINTING UPON THE INTERIOR OF ANY GLASS
OR OTHER TRANSPARENT VESSEL," to be as follows:-
Our Invention consists in printing upon the interior of any glass or other
transparent vessel, by the aid of photographic negatives, portraits, landscapes,
views, pictures, arms, devices, or ornaments. To this end we take one or
more ordinary photographic negatives of the portrait, landscape, view, picture,
arms, device, or ornament intended to be printed on the interior of the glass

page_text: or other transparent vessel upon a pliable substance, such as waxed paper, or
mica, or any other pliable and transparent material. We then fix such
negative upon the exterior of that part of the glass or other transparent vessel
wherein such portrait, landscape, view, picture, arms, device, or ornament is
intended to be affixed, and by means of a mould made of gutta percha or
other flexible material completely covering the said glass or other transparent
vessel, with the exception of an aperture of the size of the negative whereon
it is placed, the light being thus wholly excluded from all other parts of such
vessel. We then pour into such glass, or other transparent vessel, a quantity o
collodion or other suitable material, and rendered sensitive to light, which we
expose to the even light in such manner that the power of light shall act
equally around and through the transparency of the vessel upon the sensitized
substance fixed on the interior of such glass or other transparent vessel. We
then develope and fix such portrait, &c., so produced, by the ordinary process
of photography. When dry, we back the interior of such glass or other trans-
parent vessel with oil colours in imitation of marble, alabaster, wood, or any
other fancy decoration, by which means the portrait, landscape, view, picture,
arms, device, or ornament is rendered permanent, and thus protected on the
inside thereof by such body of oil paint, and on the outside it is protected by
the glass or other transparent vessel.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Hooman and John Maliszewski in the Great Seal
Patent Office on the 1st November 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
HOOMAN, of No. 490, New Oxford Street, in the County of Middlesex, Glass
Letter Manufacturer, and JOHN MALISZEWSKI, of the same Place, Photographic
Artist, send greeting.

page_text: agree with, and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS. IN PHOTOGRAPHIC
PRINTING UPON THE INTERIOR OF ANY GLASS OR OTHER TRANSPARENT VESSEL," upon
the condition (amongst others) that we, the said Thomas Hooman and John
Maliszewski, our executors or administrators, by an instrument in writing
under our, or their, or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that we, the said Thomas Hooman and John
Maliszewski, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
Our Invention consists in printing the interior of any glass or other trans-
parent vessel by the aid of photographic negatives, portraits, landscapes, views,
pictures, arms, devices, or ornaments. To this end we take one or more
ordinary photographic negatives of the portrait, landscape, view, picture, arms,
device, or ornament intended to be printed on the interior of the glass or other
transparent vessel upon a pliable substance, such as waxed paper, or mica, or
any other pliable and transparent material. We then fix such negative upon
the exterior of that part of the glass or other transparent vessel wherein such
portrait, landscape, view, picture, arms, device, or ornament is intended to be
fixed, and by means of a mould made of gutta percha or other flexible
material completely covering the said glass, or other transparent vessel, with the
exception of an aperture of the size of the negative wherein it is placed, the
light being thus wholly excluded from all other parts of such vessel. We
then pour into such glass, or other transparent vessel, a quantity of collodion or
other suitable material, and rendered sensitive to light, which we expose to the
even light in such manner that the power of light shall act equally around
and through the transparency of the vessel upon the sensitized substanced fixed
on the interior of such glass or other transparent vessel. We then develop
and fix such portrait, landscape, view, picture, arms, device, or ornament so
produced by the ordinary process of photographing. When dry, we back the
interior of such glass or other transparent vessel with oil colors in imitation
of marble, alabaster, wood, or any other fancy decoration, by which means the

page_text: portrait, landscapé, view, picture, arms, device, or ornament is rendered per-
manent, and thus protected on the inside thereof by such body of oil paint, and
on the outside it is protected by the glass or other transparent vessel.
In witness whereof, the said Thomas Hooman and John Maliszewski,
have hereunto set their hands and seals, this Thirty-first day of October,
in the year of our Lord One thousand eight hundred and sixty-one.
