PROVISIONAL SPECIFICATION.
An Improvement in Sheaths for Photographic Plates.
I, EDWIN UNDERWOOD, trading as E. & T. Underwood, of 130 and 132
Granville Street, Birmingham, Warwickshire, Photographic Apparatus Manu-
acturer, do hereby declare the nature of this invention to be as follows:
This invention consists of the hereindescribed improvement in metal and other
sheaths for photographic plates my object being to facilitate the holding and
changing of the said sheaths when in use in a flexible change bag.
According to this invention I make each of the said sheaths with a small side
projection serving as a handle of sufficient size and of a convenient shape to be
gripped by the hand through the substance of the change bag thus facilitating the
holding of the sheaths when the operator is changing them in the change bag.
The said side projection of the sheath may readily be made in a piece with the
sheath by slitting the trough like edge at two places so as to form a tongue which
is then bent outwardly from the side of the sheath and the extreme end of the
tongue is bent at right angles to enable the tongue to be held between the thumb
and finger.

COMPLETE SPECIFICATION.
An Improvement in Sheaths for Photographic Plates.
I, EDWIN UNDERWOOD, trading as E. & T. Underwood, of 130 and 132,
Granville Street, Birmingham, Warwickshire, Photographic Apparatus Manu-
facturer, 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 consists of the hereindescribed improvement in metal and other
sheaths for photographic plates my object being to facilitate the holding and
changing of the said sheaths when in use in a flexible change bag.
I will describe my invention by referring to the accompanying drawing on
which
Fig. 1 is a general view of one of the said sheaths constructed according to
this invention; Fig. 2 is a plan of the same:
Fig. 3 shews a slightly modified form of my invention; and Fig. 4 is a plan
of the same.
The same letters of reference indicate the same or corresponding parts in all
the figures of the drawings.
According to this invention I make each of the said sheaths A with a small side
projection B serving as a handle of sufficient size and of a convenient shape to be
gripped by the hand through the substance of the change bag thus facilitating the
holding of the sheaths when the operator is changing them in the change bag.

page_text: The said side projection B may be constructed in various ways. For instance as
shewn in Fig. 1 the projection B may be made in a piece with the sheath A by
slitting the trough like edge a' at two places namely a² a³ so as to form the
tongue B which is then bent outwardly from the side of the sheath as shewn
in Figs. 1 and 2, flush with the back of the sheath and the extreme end of the
tongue is bent at right angles to enable the tongue to be held between the thumb
and finger. Figs. 3 and 4 shew another method of forming the side projection B
which in this case is made of a piece of wire bent into the required form and
soldered at 62 to the edge of the sheath. In any case the handle or side pro-
.jection B must not be wider than the thickness of the sheath otherwise it will
come in contact with the next sheath case when in the camera or scratch the plate
therein.
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. Making a sheath for photographic plates with a small side projection serving
as a handle which can be gripped through the substance of the change bag when
-changing the plates, substantially as hereinbefore set forth.
2. The combination with the sheath A of the tongue B formed by slitting the
trough like sheath in two places and turning the part between the slits backwardly
and outwardly so as to form a side handle substantially as hereinbefore described
and illustrated by Figs. 1 and 2 of the accompanying drawings.
3. The combination with the sheath A of the tongue B formed of a piece of
wire bent and fixed to the side of the sheath so as to project therefrom and form a
side handle substantially as herein before described and illustrated by Figs. 3 and 4
of the accompanying drawings.
