Our invention relates to illuminating appa
ratus for photographic purposes and its principal
'object is to provide an apparatus of this kind
capable of emitting a number of ?ashes of light
in rapid succession to enable aphotographer to
take a series of pictures in a short time. Further '
objects and advantages of'the invention will ap
pear from the following detailed'description of
species thereof and from the appended claims.
In the drawings accompanying and forming
l3 over vboth of said ?anged wheels l2 and 12’.
The wheel l2’ may then be- released to travel away
from wheel l2 until its. motion is arrested by
the band l3; After the lamps l4 have been
?ashed in sequence, in the manner described in
detail hereinafter, the band _I3 is removed from
thewheels l2 and 12’ in the same manner and
a new band is inserted.
The wheel l2, which is shown partially broken
