Improvements in Lamps for Heating Purposes.
I, ARTHUR THOMAS CARLEY of 93 Northcote Road Clapham Junction in the
County of London Ironmonger do hereby declare the nature of this invention to be
as follows:-
My invention relates to mineral oil or spirit heating apparatus adapted for all
heating purposes scientific or industrial. In the accompanying drawing Fig. I is a
vertical section of a heating apparatus constructed according to my invention and
suitable for use as a plumbers soldering lamp a painters lamp for burning off paint
and like purposes. In carrying out my invention which I first describe by reference
to drawing I make use of a reservoir A provided with a handle B and suitable
filling plug C in which spirit or other suitable substance is poured Fig. D is a
suitable vessel suspended on a hook E in which is poured spirit or other suitable
substance is burned for to heat the apparatus when commencing to use same.
The vessel A is partly traversed by one parallel tube F in an inclined or other
position which is fitted with a perfectly tight screw capped joint G the tube F
extends through cap G to burner tube H and is packed with a cotton wick I asbestos
tipped. The burner tube H is connected to wick tube F by a brazed joint or made
in one casting of a suitable metal. J is a vapor passage formed in the burner
tube H communicating with N a generating space between top of wick I and
bottom of burner tube H. K is a suitable regulating screw with a stuffing
preventing any escape of vapor. L. M. are two screw plugs for cleaning out the
passages. O is a nipple or outlet for vapor.

Improvements in Lamps for Heating Purposes.
1, ARTHUR THOMAS CARLEY of 93 Northcote Road Clapham Junction in the
County of London Ironmonger 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 mineral oil or spirit heating apparatus adapted for all
beating purposes scientific or industrial, and its object is to produce an intense heat
by means of a simple effective, and portable lamp. The apparatus consists of a
tube for communicating with the oil or spirit container through a wick, and an
upper tube into which the heated spirit or oil vapour ascends and is there burnt
under pressure, producing a flame of an intense heat. The drawings referred to in
this Specification as illustrating my invention are those left with the Provisional
Specification.
The figure is a longitudinal vertical section taken through the centre of the oil
or spirit container tubes and passages.
A is a container or reservoir for the spirit or oil, and it has a handle B, and a
suitable filling plug C, in which the spirit or oil is poured before use. When in
action the lamp generates sufficient heat to volatilize the oil or spirit, but for the
purpose of producing a preliminary heating I use a small lamp D which is suspended
from a hook E. Longitudinally extending through the container or reservoir A
27

page_text: is a wick tube F, inclined (in the normal position of the lamp) at an angle to
the horizon. Where this wick tube F passes through the wall of the reservoir A
a perfectly air-tight joint is made by a screw-cap G. To the upper end of the
wick tube F and at an angle thereto is attached the burner tube H by a
brazed joint or by other convenient means; or it may be formed integral
therewith. Formed in the wall of the burner tube H is a vapour passage J
one end of which communicates with the generating space N at the top of the
wick tube F, while the other end opens into or forms a nozzle nipple, or outlet O
from which issues the vapourized spirit or oil, in such a state of minute subdivision
that it easily takes fire and burns fiercely. K is a suitable regulating screw by
means of which the passage of the vapour may be controlled and it has a stuffing
box to prevent escape of the vapour. L and M are two screw plugs, one at
each end of the passage J by the removal of which the passage may be cleaned.
In the wick tube F is a cotton wick I which is tipped at its upper end near the
generating space N with asbestos, and when the lamp is sufficiently heated the spirit
or oil ascends through the cotton and asbestos by capillary attraction is volatilized
in the generating space N passes through the passage J and nipple O and burns in
the burner tube H emitting a fierce flame at the end of the same.
This lamp is peculiarly suitable for use by plumbers and painters in soldering,
brazing burning off etc.
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. A lamp or heating apparatus consisting essentially of a reservoir, a tube filled
with a cotton wick asbestos tipped, a generating chamber, a passage for the vapour,
a burner outlet or nozzle, a regulating screw and a burner tube, substantially as
shewn and described.
2. A lamp or heating apparatus substantially as shewn and described.
