This invention relates to a battery box and
removed, the section being taken substantially
more particularly to a container for dry cells of
along line 'l—'l of Fig. 6.
A flexible blank ‘I (Fig. l) which is preferably
formed of cardboard covered with a waterproof
ing paint, is used to form the walls of the box or
container. As shown, this blank has a bottom
la from which extend side walls 8 and 9 and a
the type usually employed in ?ash lights.
One of the objects of the present invention is
to provide a novel battery box for dry cells which
is so constructed and arranged that different
voltages may be obtained from the battery by
changing the positions of the cells in the box.

blank, whereby the partition may be adhesively
secured in position in the container, if desired.
The blank is also provided with slits 23 and 23,
and a V-shaped notch 250. The latter is pro
vided to facilitate the insertion of tab Ida between
the inner face of side wall 8 and the adjacent
edges of partitions if! when the container cover

Novel means are provided for operatively con- -
necting each cell to the next adjacent cell in
series, said means being so formed as to insure a

order that these two contacts may be more closely
situated, the end portions may be bent at an
angle as ShOWn in Fig. l. Preferably all of the
conducting strips are passed through their respec
tive slits before the blanks are folded and the
folded partition blanks are positioned so that the
bottom of slots 28 in blanks 25 engage the bottom
of slots 2| in the blank 20.
In certain instances it is highly desirable to
vary the voltage of the battery. This can be
readily done by inserting one or more of the cells
34 upside down within the container. If each
cell, assuming a battery of six cells, is inserted
into the box with the center electrode down and
in contact with portions 24b of the contact strips
