COMPLETE SPECIFICATION.
An Improved Lamp for Heating, Ventilating, Fumigating, and other
like purposes.
I JAMES PATRICK MANTELL of Galgorm, Ballymena, in the County of Antrim,
Gentleman, 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 is principally intended for use in hospitals, sick rooms and nurseries
to afford light, heat and fresh air and also for use for disinfecting and as a means
for warming food but may also be applied to other purposes.
To enable my invention to be fully understood I will proceed to describe the
annexed sheet of drawings which is intended to illustrate my said invention. I
construct lamps having a reservoir for oil a, Figure 1, surmounted by a burner b of
ordinary construction either with or without a glass chimney. The burner is
surrounded by a glass globe c which rests upon a hoop or ring & attached to the oil
reservoir. This ring is provided with an inlet tube e for admission of air to support
combustion.
The globe c is protected by three or more vertical bars which support a hot air
casing 9 which is provided with an inlet pipe h for admission of air, and also an
outlet for exit of heated air.
g
Within the said hot air casing is formed a dish or vessel k for water containing
carbolic acid, or other disinfectants, or otherwise medicated, which by evaporation
due to the heat afforded by the lamp becomes diffused throughout the apartment in
which the lamp is used.
On the top of the hot air casing I place a box in open communication with the
lamp having an outlet pipe m to carry away the products of combustion; I con-
struct this box with a thin metallic cover placed above the burner of the lamp in
such a manner that a pan or vessel containing food, etc. by being placed upon it
would thereby become heated and its contents kept warm and ready for use.
I may use other media for obtaining heat besides oil, such as gas, benzoline,
naphtha, etc., and the inlet pipes for air as well as the outlet pipe are preferably
placed in open communication with the outside air so as to utilize the lamp when
lighted as a means of ventilation.
I use a special device for jointing the pipes which unite in a nipple n, Figure 2,
which fits into a socket o both having a screw thread chased upon their outside cir-
cumference so that when they are put together a nut p is screwed over them which
covers the jointing of the nipple and socket and renders them tight and allows them
to be readily separated and re-adjusted. Figure 2 shows the nipple and socket
separated and Figure 1 shows them covered by the nut p. Figure 3 is an end view
of same.
I do not limit myself to the precise arrangement of details herein described but
may vary them to suit the position of the lamp should it be suspended or held by a
bracket or otherwise supported.
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. The construction and use of a lamp for lighting, heating, ventilating and
disinfecting substantially as described and as shown upon the accompanying

page_text: 2. In the construction of such lamp the use of a nipple and socket and a nut to
cover and secure them for the purpose of connecting the pipes in the manner shown
in Figures 1, 2 and 3.
