page_text: We PASQUALE VALENTINO FANTINI and SAMUEL JOHN MUIR both of No. 435
Fulham Road West Brompton in the County of Middlesex Photographers do
hereby declare the nature of this invention to be as follows:-
It consists of two proportionate sized cases made in wood or metal also lined
with glass to allow the ordinary powder to be burnt within it under a clear or
colored broad glass chimney to carry all or a greater part of the white coating that
always settles on any open lamp where the powder is allowed to burn in an open
pan. Also instead of having the light reflected by looking-glasses, we use ordinary
white calico on rollers which gives a far softer light than the looking glasses,
which of course is a greater boon to the sitter. This apparatus is so formed that
it can be placed a considerable distance from the sitter and one apparatus is placed
each side of the room so as to take either or one side of the figure by a very simple
and rapid alteration of the reversible blinds in front of the apparatus, thus it gives
to every photographer a great boon, to be able at any time to meet the require-
ments of his patrons when the reversed side is required as we know in most cases
in artificial light photography it is very often a denial or an excuse, is necessary as
only one side can be taken. Only one opening in any room or studio is required
to carry off the fumes as the two apparatus's are connected together with one
outlet. The light can be started by the aid of gas but the inventors have succeeded
& especially claim the use of electricity for the purpose of starting the light
therefore having electricity fitted to the apparatus where gas is not convenient,
electricity can be used.

An Improved Lamp for Use in Photographic Studios.
We PASQUALE VALENTINO FANTINI and SAMUEL JOHN MUIR, both of No. 435
Fulham Road, West Brompton, in the County of Middlesex, Photographers, do
hereby declare the nature of our invention for "AN IMPROVED LAMP FOR USE IN
PHOTOGRAPHIC STUDIOS," and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
The device according to our Invention consists of two proportionately sized
transparent cases A, A, furnished on one side with suitable doors, within which
cases, and immediately beneath conical chimneys F, F, of clear or colored glass, are
carried the enamelled pans E, E, in which the ordinary powder used for producing
a bright light is to be burned.
The cases A, A, aforesaid, to which are attached the glass cones F, F, are
arranged in any convenient positions in the studio or room, above which is a
branched outlet flue G, for the purpose of carrying off the fumes and vapors
generated by the burning powder above referred to. In order to prevent the
ingress of these vapors into the room by down drafts, which is not only troublesome
to the occupants, but also result in deposits of a filmy form upon surrounding
objects, we use a flue of special formation, as shown in the drawings. The lateral
tube or flue f, f¹, is furnished with a vertical uptake G, closed at the top, and
provided with pendant branches g, g¹, each of which is open at the bottom only:
said pendant passages or tubes, it will be seen also at the points of junction with
the vertical tube G, are disposed so as to break joint relatively to each other.
At the base of the transparent cases A, A, aforesaid, we fix suitable gas jets, for
the purpose of further increasing the upward draft.
At C, is a rod upon which slides the arm terminating in a ring E, which ring
carries the enamelled pan aforesaid, containing the powder, to the gas jet D, by
which means the light can be readily and conveniently started. Electricity may
however be used for said purpose instead of gas, and especially where gas is not
obtainable.
It has hitherto been customary to use mirrors for the purpose of reflecting the
light upon the sitter, but we find in practice that we can obtain a softer light by
the adoption of a system of blinds forined of ordinary white calico fixed upon
rollers, by which means the brilliancy of the light can be regulated to suit the
various requirements.
From the foregoing it will be seen that according to our Invention, we are
enabled to take either one side or the other of the sitter, accordingly as may be
desired, by a simple and rapid alteration of the blinds aforesaid. A full length
portrait can also be taken with equal facility; and the apparatus and parts thereof
being very compact and of light construction, they can be easily adjusted to any
studio or room,

page_text: Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is
Firstly: The improved lamp and accessory parts, for use in Photographic
studios, substantially as herein described, and illustrated in the accompanying
drawings.
Secondly-The placing of a light at each side of the room or Photographic
studio, and mode of applying said lights together or separately, substantially as
herein set forth.
Thirdly The mode of and means adopted, by the use of jets of gas or
equivalent for producing an upward draft within the cases A, A, for conveying
away all fumes and vapors, substantially as herein described and illustrated in the
accompanying drawings.
Fourthly The adoption of glass cones for facilitating the outflow of the fumes
and vapors, and preventing the deposit of a film upon surrounding objects,
substantially as herein described and illustrated in the accompanying drawings.
Fifthly In connection with the apparatus herein described, the special
arrangement of chimnies or flues, substantially as and for the purposes herein
described and illustrated in the accompanying drawings.
