A New or Improved Flash Lamp for Use with Apparatus for
Exhibiting Views, and other Purposes.
ALFRED JAMES SWAAB, and RODOLPHE DE LAMPRECHT, both of 105, Hatton
Garden, London, E.C., Gentleman, do hereby declare the nature of this invention
to be as follows:-
This invention consists of a new or improved flash lamp for use with apparatus
for exhibiting views, & other purposes. In carrying out my invention I provide
a support having the required number of compartments. These compartments are
for the purpose of carrying a flash powder, which is ignited through the operation
of a current of electricity. The switch provided is so arranged that the powder
in the required number of compartments may be ignited, this ignition taking
place owing to the heating effect of the current with which the powder is in
term a condensor for
contact. An important feature of my invention is what
the purpose of condensing what may be called smoke. This condensor consists
of a suitable chamber which is supported above the apparatus, & after the powder
has been ignited, the smoke or objectionable fumes are condensed. The essential
feature of the condensor consists in the employment of iron filings, or turnings
which thus forms a sieve or filter. The flash light may be used for any required
purpose such as photography.

A New or Improved Flash Lamp for Use with Apparatus for
Exhibiting Views, and other Purposes.
ALFRED JAMES SWAAB, and RODOLPHE DE LAMPRECHT, both of 105, Hatton
Garden, London, E.C., Gentleman, 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:-

vide a support having the required number of compartments. These compart-
ments are for the purpose of carrying a flash powder, which is ignited through
the action of a current of electricity. The switch provided is so arranged that
the powder in the required number of compartments may be ignited, this ignition
taking place owing to the heating effect of the current with which the powder is

An important feature of my invention is what 1 term a condenser
for the purpose of condensing what may be termed smoke. This condenser con-
sists of a suitable chamber which is supported above the apparatus, and after the
powder has been ignited the smoke or objectionable fumes are condensed. The
essential feature of the condenser consists in the employment of iron filings or
turnings which thus forms a sieve or filter. The flash light may be used for any
required purpose such as photography.
For purposes of illustration I will now refer to the annexed drawings in
which:-
Figure 1, is a perspective view shewing my invention.
a is a support which carries the compartments b. These compartiments are
for the purpose of carrying the required flash powder or composition. The
contact pieces are provided upon the sides of the support and are so arranged
that the support a may he removed from the piece d when required and another
one inserted carrying a fresh charge of flash powder after the previous one has
been consumed. The springs e and contact pieces are in electrical communica-
tion with is current through the medium of a switch f so arranged that the
powder in the required compartment may be fired this being effected through
the heating effect of the current passing through a coil of wire or by means of a
spark. Any suitable source of current may be employed. The chimney g is
filled with a composition such as sawdust and iron filings or turnings for the
purpose of condensing or retaining the smoke or fumes which arise upon the
ignition or flashing of the powder. By this arrangement it will be seen, that
according to the number of compartments so many flashes may be obtained, and
when required the support carrying the compartiments may be removed, and a
fresh one substituted therefor and the flash powder ignited as before owing to
the passage of the electric current.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. The flash light apparatus substantially as described and illustrated herein
and for the purpose set forth.
2. The flash light apparatus in combination consisting of a support having com-
partments in which the flash powder is carried said support being removable from
abase provided with electrical contacts for the purpose of enabling a current to
be passed through a coil of wire or a spark to be produced in contact with the
flash powder, a switch for enabling the current to be passed through the required
compartment. A chimney or funnel containing sawdust iron filings or turnings.
supported above the compartments at the required height for the purpose of
condensing or receiving the smoke or fumes arising after the flash or ignition of
the flash powder, substantially as described and illustrated herein and for the
purpose set forth.
