IMPROVEMENTS IN LAMPS OR LANTERNS
Year: 1884

page_text: I, JACOB HENRY RADCLIFFE 36 Landseer Street Oldham in the County of
Lancaster Iron and Tinplate Worker do hereby declare the nature of my invention
for IMPROVEMENTS IN LAMPS OR LANTERNS to be as follows:-
:
I apply a new kind of ventilating top for a globe lamp or lantern wherein oil
or gas forms the medium for combustion. This top I make for the inlet of the
ordinary air heated to a high degree to support combustion I make a cased tube
one way for the inlet of the air, the other one for the outlet of the products of the
flame. I also make arrangement for supplying ordinary air at the bottom of the
globe lamp or lantern where it is neccesary by a perforated tin bottom or where
the lamp is hung the gas tube and medium for combustion are passed from above
into the globe lamp or lantern having a large round hole at the bottom of the
same. I place a glass ball larger then the hole to fill up the hole so as to allow it
being pushed aside for lighting purposes, when lighted the glass ball rolls in its
place in the hole and prevents the great rush of air which would materially affect
the light I apply this kind of a ventilating top part to various shapes or
configurations of lamps varying some little in shape or configuration of ventilating
tops to suit the various shapes of lamps for lighting and heating purposes.

JACOB HENRY RADCLIFFE 39 Waterloo Street Oldham Lancashire Iron & Tin-
plate Worker do hereby declare the nature of my invention for IMPROVEMENTS
IN LAMPS OR LANTERNS and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
I apply a new kind of ventilating top for a globe-lamp or lantern wherein oil
or gas forms the medium for combustion. This top I.make for the inlet of the
ordinary air heated to a high degree to support combustion. I make a cased tube
one way for the inlet of the air and the other for the outlet of the products of the
'flame. I also make arrangements for supplying ordinary air at the bottom of the
globe lamps or lanterns where it is neccesary by a perforated tin bottom or where 1
the lamp is hung the gastube and medium for combustion are passed 'from above
into the globe-lamp or lantern, having a glass ball larger then the hole to fill the
hole up so as to allow it being pushed aside for lighting purposes When lighted
the glass ball rolls back in its place in the hole & prevents the great rush of air
which would materially affect the light. I apply this kind of a ventilating top
part to various configuration of lamps varrying some little in shape of ventilating
tops to suit the various shapes of lamps for lighting and heating purposes..
REFERENCE TO DRAWING.
Fig. 1 represents a single light in a lamp, this form is suitable for use inside,
but in case it be required for outside purposes I fix it within any other form of
lamp so that the cold air will not act on it or prevent the combustion of the gas
but inside a building it is not necessary to be in another lamp as in a room the
temperaturo and currants of air do not affect it therefore a steady light more
complete combustion and more illuminating power is given.

section of ventilating top which I make of tinned iron plates The arrows denote
the passage of the air to support combustion. The bottom plate R I perforate and
in the centre I cut an oblong slot. This bottom plate I rivit at K to the flange of
the inner chimney. The top of chimney I also perforate at S for a passage for
the results of combustion. This top I attach to a rim to pass on the globe and on
which I fix ears V for wires to pass from this rim to the carriers T of globe The
top I attach to the rim by means of a hinge W this I apply for the special purpose
of lighting; so that when I pass into the globe a light cased round by a perforated
tube: The top of this tube opens the top cover before the gas is lighted thereby
preventing an explosion by the carburated hydrogen gas (which would accumulate
in the globe from the time the tap was turned on until the lighting tube ignited
the gas at the burner) The tube being drawn out the lid closes and the slide
being replaced at the bottom, or, in case the bottom (Fig. 4) is used the ball (G)
rolls in its place and partly closes all apertures which might interfere with the
combustion or steadiness of the flame.

I leave a passage for a tube perforated and within which tube is a light for lighting
purposes this tube being of a sufficient length to lift the ventilating cover up
previous to the light coming in contact with the gas emitted from the burner.
Fig. 3 represents another kind of bottom carrier of the globe made of tin or
other metal. A forms a rim which I perforate round with small holes about the
point of A. This carrier I place within a perforated bottom of tin or wire
gauze B upon this wire gauze I place two wire rings C C attached to wire pillar D
and gas pipe E in the form of two circular inclined planes, the ends of these wires
I attach to an inner tube F or plate B or all three together. G is a glass ball or
any kind of a ball and is readyly moved when the tube for lighting is passed into
the globe up the circular_inclined planes and rolls back again in its place partly
making up the passage F when the lighting tube is taken out after lighting the
On the rim A I attach three strips of brass to put three screws in to fix
globe to the galliery or carrier.

Sheet No. 2 represents an illustrated sheet of my invention, the object of which
is to gain a more complete combustion and a steadier light.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I do declare that
what I claim is
The arrangement of the globe top and bottom substantially as set forth herein.
