My invention relates to illuminating apparatus
for photographic purposes and its principal ob-v
ject is to provide an apparatus or device of this
kind accommodating a plurality of ?ash lamps
and capable of emitting a number of ?ashes of
light in rapid succession to enable a photographer
to take a series of pictures in a short time. Fur

The lever arm 32' is pivoted at 34 on_ the plate
25 so as to‘ be movable in a circular arc in the
direction indicated by the arrow (Fig. 2). The
movement of arm 32 in the direction of the ar
row and in the opposite direction is limited by '
the ends of arcuate slot 33 in plate 25. The arm
32 is provided with a handle 35 normal thereto.
The pivoted end of arm 32 has a projection 36
