page_text: I, SAMUEL CLARKE of the Pyramid Works, Childs Hill, in the County of
Middlesex, Candle and Night Light Manufacturer, do hereby declare the nature of
this invention to be as follows:-
My invention relates to lamps of that kind in which the lower part of the lamp
is formed of a glass or porcelain cup within which a short candle or oil lamp is to be
contained and which is covered over with a dome shaped shade also of glass.
Such lamps are described in the Specification of a former Patent granted to me
No. 11353 in the year 1885.
In order to improve the admission of air to the interior of such lamps I form them
with a central hole through the bottom of the cup and with radial grooves or
corrugations on the inside passing from this hole to the sides and the sides I form
with similar grooves or corrugations passing up them.
In this way a very uniform distribution of air all around the candle is obtained so
that the candle burns steadily without flickering.
The rim or flange of the glass cup upon which the dome shaped shade rests may
also be made with radial corrugations across it so that as before air may pass to the
candle through these corrugations.
When the lamp is at times required when burning to be stood upon a table or
other surface the under side of the bottom of the glass cup must be made with any
suitable projections standing downwards from it so that the cup may rest on these
projections and allow a free passage of air to the central hole.

page_text: I, SAMUEL CLARKE of the Pyramid Works, Childs Hill, in the County of Middlesex,
Candle and Night Light Manufacturer, 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 :-
My invention relates to lamps of that kind in which the lower part of the lamp is
formed of a glass or porcelain cup within which a short candle or oil lamp is to bo
contained and which is covered over with a dome shaped shade also of glass. Such
lamps are described in the Specification of a former Patent granted to me No. 11353
in the year 1885.

In order to improve the admission of air to the interior of such lamps I form them
with a central hole through the bottom of the cup and with radial grooves or
corrugations on the inside passing from this hole to the sides, and the sides I form
with similar grooves or corrugations passing up them.
In this way a very uniform distribution of air all around the candle is obtained so
that the candle burns steadily without flickering.
The rim or flange of the glass cup upon which the dome shaped shade rests may
also be made with radial corrugations across it so that as before air may pass to the
candle through these corrugations.
When the lamp is at times required when burning to be stood upon a table or other
surface the under side of the bottom of the glass cup must be mado with any suitable
projections standing downwards from it so that the cup may rest on these projections
and allow a free passage of air to the central hole.
The drawing annexed shews two examples of lamps formed as above described.
Figure 1 is a vertical section of one of the forms and
Figure 2 a plan view with the dome cover and candle and candle holder removed.
Figures 3 and 4 are similar views of another form.
The lamp shewn at Figure 1 is provided with an inner cup for the candle to be
placed in whilst that shown at Figure 3 has a candle within it that requires no
inner cup.
In these figures A is the glass cup forming the exterior of the lower part of the
lamp B is the ordinary dome shaped shade-C in Figure 1 is an inner cup for
holding a candle-D is the candle-E is the hole formed through the centre of the
bottom F F are short legs or projections on the underside of the glass cup-G G are
radial projections on the upper surface of the bottom of the cup-G' are vertical
corrugations on the inner surface of the sides of the cup.
In both of the lamps the upper surface of the rim or flange of the cup is also shown
to be corrugated to allow air to pass below the dome shade as is usual but the lamps
may if desired be made without these corrugations on the rim or flange.

page_text: 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 glass or porcelain lamp formed with an air passage through the bottom
substantially as described.
2. The glass or porcelain lamp formed with an air passage through the bottom and
with projections standing up from the upper surface of the bottom for the candle or
candle holder to rest on.
3.-Glass or porcelain lamps formed substantially as herein before described and
illustrated in the drawing annexed.
