PROVISIONAL SPECIFICATION.
An Improved Box for Photographic Plates.
I, FREDERIC BARRETT of 165 Queen Victoria Street, in the City of London,
Publisher, do hereby declare the nature of this invention to be as follows:-
This invention relates to the manufacture of an improved box for containing
photographic dry plates. the main object of the improvements being to provide a
box which, while being light shall be strong and light-proof.
In manufacturing my improved box I form the ends thereof of wood provided
with a number of vertical grooves placed at a suitable distance apart, and adapted
to receive the edges of the plates, the outer grooves serving to receive the sides
of the box also made of wood and adapted to be slid in or
out. The permanent
sides of the box as well as the bottom thereof are made of cardboard or the like.
The space between the removable wooden sides and the permanent cardboard sides
of the box serves as a cushion against the effect of blows or pressure during transit
or otherwise.
In practice I find it advantageous to provide the upper edges of the box with
a flap of non-actinic paper to be folded over the edges of the plates before the lid
is placed over the box as a further protection against the entrance of light par-
ticularly after the box has been once opened.
The lid of the box is made of cardboard and is adapted to fit over the top of
the box as usual. The bottom of the box as well as the inside of the lid is
advantageously strengthened by means of a thin piece of wood or of corrugated
paper packing.
By this improved construction of box I obtain absolute security against the
entry of light combined with rigidity at the same time that the plates can be
placed in and removed from the box with facility, and efficient protection against
injury is afforded to the plates during transit and otherwise.

An Improved Box for Photographic Plates.
I, FREDERIC BARRETT, of 165 Queen Victoria Street, in the city of London,
Publisher, 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 relates to the manufacture of an improved box for containing
photographic dry plates, the main object of the improvements being to provide a box
which while being light shall be strong and light-proof.
In order to enable my invention to be fully understood I will describe the same
by reference to the accompanying drawing in which
Figure 1 is a plan of a box for photographic plates constructed according to my
invention, the lid of the box being removed and the paper flaps opened out.
Figure 2 is a longitudinal section of the box and its lid, and
Figure 3 is a transverse section of the same.
In manufacturing my improved box I form the ends a, a¹ thereof of wood pro-
vided with a number of vertical grooves b. b, b placed at a suitable distance apart
and adapted to receive the edges of the plates, the outer grooves c, c serving to
receive the sides d, d of the box also made of wood and advantageously adapted to be

or made of cardboard or the like. The space between the removable wooden
sides d and the permanent cardboard sides e of the box serves as a cushion against
the effect of blows or pressure during transit or otherwise.
In practice I find it advantageous to provide each of the upper edges of the box
with a flap of non-actinic paper to be folded over the edges of the plates before the
lid is placed over the box as a further protection against the entrance of light
particularly after the box has been once opened.
The lid of the box is made of cardboard and is adapted to fit over the top of
the box as usual. The bottom of the box as well as the inside of the lid is advan
tageously strengthened by means of a thin piece of wood or as shown in the drawing
by corrugated paper packing j.

By this improved construction of box I obtain absolute security against the entry
of light combined with rigidity, at the same time that the plates can be placed in and
removed from the box with facility, and efficient protection against injury is afforded
to the plates during transit and otherwise.
•
is the usual band or tape for facilitating the removal of the plates.
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 :-
