I, CHARLES RICHARD STEVENS 292 Brockley Road, S.E. in the County of Kent
Mechanical and Sanitary Engineer do hereby declare the nature of my invention
for IMPROVEMENTS IN SIDE REFLECTING LAMPS FOR SHOP FRONTS AND LIKE
PURPOSES to be as follows:-
The frame is V shaped at sides the front longer than the back the top is flat and
hinged to the upper front part of frame with a fastening at the back for opening
and closeing the lamp the top is made with an oblong chimney or oulet with a
double rim round the outer edges a space is left between the frame and top for
inlet the air entering is deflected down the sides of glass to keep it cool from the
heat of the flat flame burner or burners which are fixed under the oblong opening
the flat part in a line with the front of lamp.

CHARLES RICHARD STEVENS 292, Brockley Road, S.E. Mechanical Engineer,
I do hereby declare the nature of my invention for IMPROVEMENTS IN SIDE
REFLECTING LAMPS FOR LIGHTING SHOP FRONTS AND LIKE PURPOSES and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The frame of lamp is V shaped at sides the front of lamp being longer than the
back the top of lamp is preferably flat and in the small or portable lamps is hinged
to the front part of the frame of lamp with a suitable fastening, at the back of
lamp for opening and closing same and in the large or fixed lamps the top is fixed
to the frame and the door is made to open at the back but it is obvious that,
without departing from the nature of the Invention the details so far as the door
or opening to the lamp it can be made to open at the top back front or sides as
may be found best in practise. The top of lamp is made with an oblong chimney
or outlet perforated with a cap or cover not perforated over the top of the outlet
and under the top of the lamp is fixed a reflecting top in white enameled iron
earthenware or suitable reflecting material with a chimney not perforated smaller
than the perforated chimney in the top of lamp and not so long leaving an annular
space round them and space at the top for the hot air to escape a single or double
rim is fixed round the sides of the top of lamp forming a windguard round the inlet,
the air in entering the lamp is deflected down the sides of the glass to keep it cool
from the heat of the burners and also to stop the wind from blowing the burners
about, the gas burners are fixed under the oblong opening the flat part of flame is
in a line with the front part of lamp and as a further protection from down
draught and to get a steady light the ventilation of the lamp is also constructed as
follows. The reflecting top is fixed at a suitable distance from the top of lamp
about half an inch more or less as may be required and also leaving a space about
half an inch more or less all round the sides of the upper part of the front of the
frame of lamp and dispensing with the inlet round the top part of frame of lamp
which is not perforated, the action is as follows the air for combustion enters
through the lower part of the perforated chimney and then passes between the top
of lamp and the reflecting top and enters the lamp round the upper part of sides
and front of lamp the hot air escapes up the chimney in the reflecting top and out
through the perforated top of lamp, in using the Albo Carbon burners with this
lamp the gas supply is made to pass through the outlet so as to be heated by the
gas burners the holders for the Albo Carbon are fixed at the back part of lamp on
the top with a suitable non-conducting material round the holders to protect them
from the atmosphere in the large or fixed lamps the holder for the Albo, Carbon
can be fixed inside the lamp as there is more space with a suiteable arrangement of
the gas burners in a straight line the lamp is specially constructed for a flat flame
burner but it is also applicable for any other kind of burner or the Electric
light, the accompanying drawing illustrate several modes of constructing the lamp
I however reserve the right to vary the mere details (viz) so far as making the

that may be found necessary in the manufacture or ventilation of the lamp.

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 shape of the lamp the object of which is to keep the glass as far away
as possible from the burners considering the size of the lamp and also for reflecting
the light on one side.
(2) the construction of the top so as to reflect the light on one side only.
(3) the arrangements for ventilating the lamp so as to get a steady flame.
(4) the arrangements for charging the gas with Albo Carbon so as to protect the
reservoirs from the temperature of the atmosphere by having a double case and
filling the space with a suitable nonconducting material.
