Improvements in and connected with Lighting Apparatus for Taking
Photographs at Night or in Dull weather.
I, THOMAS MALONI, of 29 Newmarket Street, in the Town and County of Ayr,
North Britain, Photographic Artist, do hereby declare the nature of this invention
to be as follows:-
This invention has for its object to provide an apparatus which will enable
photographs to be taken at night or in dull weather.
In carrying my invention into practice I provide a telescopic stand on which
there are carried suitable movable brackets, and on these brackets there are
carried four or more magnesium ribbon lamps which can be adjusted to any
suitable angle according to style of lighting required. To the top part of each
of these lamps I have an india-rubber bag, each of which is connected to one
end of a flexible air tube, the other ends of these tubes lending into a single
tube, at the end of which there is connected a pneumatic ball. For each of these
lamps I provide a movable gas bracket, the gas being simultaneously supplied to
each of these by means of a single flexible tube..
When the apparatus is to be used the lamps are adjusted to suit requirements,
and the pneumatic ball pressed. This causes air to pass through the air tubes
simultaneously and into the air bags, which becoming distended press against the
levers at top of lamps, and, raising these up, sets the clockwork in each lamp
simultaneously in motion and this unwinds the coil of ribbon in the lamps, and
immediately the ribbon projects beyond the nozzle of the lamp it becomes ignited
by means of the flame of gas, thus causing a continuous light, and so enabling
any exposure to be given.
The apparatus is so arranged that it can be taken down or folded and so take
up little room in carrying it from one place to another, for instance in the case
of attending ball rooms.

COMPLETE SPECIFICATION.
Improvements in and connected with Lighting Apparatus for Taking
Photographs at Night or in Dull Weather.
I, THOMAS MALONI, of 29 Newmarket Street in the Town and County of Ayr
North Britain, Photographic Artist 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:—
This invention has for its object specifically to provide an apparatus which will
enable photographs to be taken at night or at any other time when the natural
light of day cannot be depended upon for producing good results in practising
the art.
%
In order that my invention may be properly understood and readily carried into
effect by others skilled in the art to which it appertains, I have hereunto appended
an explanatory sheet of drawings, in the two figures of which corresponding parts
are indicated by the same letters of reference?

page_text: Figure 1 is a general view of the apparatus looking from the back.
Figure 2 is a perspective view, drawn to an enlarged scale, looking from the
side, of a part of the apparatus sufficient to illustrate the nature of the invention
and demonstrate its efficiency.
The main stand or pillar is marked A, and is made telescopic to permit of the
sliding rod B, to move freely up and down within it. The said sliding rod B, can
be fixed at any elevation, relative with the requirements of photography, by a
clamping screw b. The stand or pillar A, is supported at its lower end on a
tripod A¹, and auxiliary stays or side rods A*, impart further stability to the base
of the apparatus. Two or any suitable number of brackets or arms C, are, or may
be, disposed around the sliding rod B, at right angles to it, and preferably, but not
exclusively, opposite to each other. They are clamped in position by the thumb
screws c.
On these brackets C, are mounted the lamps D, and their necessary fittings,
which I shall now proceed to describe. The lamp consists of an ordinary gas
jet G, a reflector D', which is placed at the back of the flame; in front of the flame
a screen D³, of waxed paper is projected, through which the light is caused to pass
in suitably subdued tones.
A socket or eye C¹, to which the lamp bracket D', is connected, enables the
lamps D, to be adjusted to any angle and clamped to the brackets C, by the
screws c. The clockwork (which forms no part of my present invention) is
contained in a cylindrical box E, and which feeds the magnesium ribbon F, to the
gas jet G. For bringing into action the clockwork I mount on the top of the said
box E, an india-rubber bag or sac 'H, which is capable of being distended or
collapsed, due to pneumatic means, and to which I shall presently have reference.
A lever I, pivoted at J, and carried in a suitable guide K, rests upon the said
bag H. The outer end of the said lever I, is connected with a vertical lever L, and
this again to a horizontal lever M, which controls the clockwork. In the containing
box E, the magnesium ribbon is carried on a drum, (not shown in the drawings)
and by virtue of the tubular passage, or conduit N, when the clockwork is brought
into action, and the said magnesium ribbon is being unwound, finds a pathway
immediately over the flame where it is ignited, seen particularly in Figure 2.
Gas is led to the jets G, of the lamp D, by the tube P. Each lamp D, receiving
its supply from a main tube Q simultaneously.
Although I have shewn the main tube Q, arranged as seen in Figure 1, it is to
be understood that it may be connected centrally with all the lamps.
Each cylindrical box E, is fitted with an india rubber bag or sac H, as has been
already described with reference to Figure 2; and each is provided with a
pneumatic rubber tube R.
Direct communication is obtained to each of the said tubes R, from the main
tube S, which terminates in a pneumatic ball T. It will be seen that the point of
ramification is made at U, by means of a nozzle piece V.
The ball being pressed a pneumatic action is set up synchronously in all the bags
or sacs H, which action raises the levers 1, L, and M, starts the clockwork, unwinds
the magnesium ribbons F, which becoming ignited allows the exposure to be made.
When pressure is taken off the ball T, the respective bags or sacs H, become
aimultaneously collapsed, and the clockwork of each lamp D, is as instantaneously
brought to a stop.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In an apparatus for producing artificial light to be used for photographic
purposes, the pneumatic device for actuating the clockwork of any number of
lamps in order to feed the magnesium ribbon to the gas jets simultaneously
whereby the illumination is greatly intensified.
2. The general arrangement and combination of parts constituting the apparatus

page_text: substantially as and for the purposes hereinbefore described and shewn in the
accompanying sheet of drawings.
