PROVISIONAL SPECIFICATION.
Improvements in Ships' Globe and other Lamps for Burning
Petroleum and other like Oils.
JOSEPH LUCAS and HARRY LUCAS The "Tom Bowling" Lamp Works Little King
Street, Birmingham Lamp Manufacturers do hereby declare the nature of this inven-
tion to be as follows:-
Our invention relates to improvements in ship's globe and other lamps constructed
to burn petroleum and other like inflammable oils and has for its object the making of
the said lamps safer and more convenient in use and practically wind proof.
We will describe the improvements as applied to globe lamps.
We make the bottom rim of the lamp in two parts-really two rims-an upper and
a lower rim. The upper rim carries the globe and receives the guards which may be
either soldered or rivetted or made movable by being fitted into sockets or eyelets
soldered to the rim as in our "Tom Bowling" globe lamp.
The lower rim has a perforated boitom covered by a wind guard and is fixed to the
foot or reservoir of the lamp by short legs or other convenient means so as to allow a
free air space between the top of the reservoir and the perforated bottom.
The upper rim carrying the globe is hinged and fastened to the lower rim so as to
be opened or removed for lighting, cleaning etc.
The burner which may be either a chimney or a chimneyless one is fitted into a collar
which passes through the perforated bottom and wind guard to the foot or reservoir
and the winder is extended between the rims to the outside of the lamp so as to allow
of the light being regulated without opening the lamp.
The head or top of the lamp is fitted with a metal chimney which extends down-
wards into the lamp over the burner and upwards into the head above the outlet
ventilation holes which are made in and round the head. This chimney made
movable by having a circular plate or stamping round it with a downturned edge
which fits over the upturned edge of a plate fixed inside the head.

Improvements in Ships' Globe and other Lamps for Burning
Petroleum and other like Oils.
JOSEPH LUCAS and HARRY LUCAS The Tom Bowling Lamp Works, Little King
Street, Birmingham, Lamp Manufacturers, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
Our invention relates to improvements in ship's globe and other lamps constructed
to burn petroleum and other like inflammable oils and has for its object the making of
these lamps safer and more convenient in use and practically wind-proof.
We will describe our improvements as applied to globe lamps and the accompanying
drawings will aid our description.
We make the bottom rim of the lamp in two parts-really an upper and a lower
rim, slightly overlapping and marked A and B in Fig. 1. The upper rim carries the
globe G and receives the guards D which may be fixed by any convenient method.
The lower rim B, has a perforated bottom E covered by a wind guard H, resting on
studs as shown in fig. 2, which is an enlarged sectional drawing of the foot or
reservoir J, the rim B. and the burner M. The rim B. is fixed to the foot or

page_text: reservoir J. by short legs K. or other convenient means so as to allow a free air
space S. between the top of the reservoir and the perforated bottom E.
The upper rim A. fig. 1, is hinged and fastened to the lower rim B, so as to be
opened or removed for lighting or cleaning.
The burner M. which may be either a chimney or a chimneyless one, is fitted into a
collar which passes through the perforated bottom E, to the foot or reservoir J. and
the winder W. is extended between the rims A. B. as shown in fig. 1. to the outside of
the lamp, so as to allow of the light being regulated without the trouble of opening the
lamp.
The head or top of the lamp shown in enlarged section in fig. 3. is fitted with a
metal chimney P. which extends downwards into the lamp over the burner, and
upwards to a suitable height in the head. This chimney P. is made movable by
having a circular plate or stamping T. fixed round it with a downturned edge which
fits over the upturned edge U, of a plate fixed inside the head. The head or top
which we illustrate has a number of outlet ventilation holes in it covered on the outside
by a corrugated covering Y, but what is known as a miller's head or any other suitable
form of head may be used.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is,
1. In a ship's globe or similar lamp constructed for burning petroleum or other
inflammable oil, the combination of the rims A. B. the movable wind guard H, the
free air space S, and the reservoir J. as described, and illustrated in figs. 1 and 2.
2. In a ship's globe or similar lamp constructed for burning petroleum or other
inflammable oil, the moyable chimney P. fitted into the head of the lamp as described,
and illustrated in fig. 3.
