Improvements in Vapour Lamps or Burners.
I, WILLIAM EDWARD SMITH, of 39 Victoria Street, Westminster, in the
County of London, Engineer, 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 apparatus for volatilizing and burning benzoline and
other liquid hydrocarbons for heating purposes, and is designed to improve the
construction and increase the efficiency of such apparatus.
An important feature of my said invention is the use of a cotton or other wick
for conducting the oil or spirit from the container to a chamber wherein it is
vaporized and whence the vapor issues through a small orifice into a tube in which
it is mixed with air before being ignited, the air entering the said tube through
suitable apertures.
Another important feature of my said invention is the provision of a small tube
for conducting any vaporized oil or spirit from the upper part of the container into
the aforesaid vaporizing chamber, and thus preventing the production of any
undesirable pressure in the said container and obviating liability to explosion of the
lamp, and at the same time facilitating the upward movement of the vapour from
the said wick.
My said invention, moreover, comprises other improvements hereinafter
described.
In the, accompanying drawing I have shown how my said invention may be
conveniently and advantageously carried into practice.
Figure 1 is a vertical central section of one form of my improved vapour lamp.
Figure 2 is a horizontal section on the line e, xr, Figure 1, showing the apertures
for the admission of air.
Figure 3 is a side elevation illustrating a detail of construction.
A is the vessel or receptacle for containing the volatile oil or spirit. B is a
metal tube, serving as a holder for a cotton or other wick C and extending from the
bottom of the vessel A through the top thereof. The said tube B is firmly secured
by soldering or brazing or in any other convenient manner in the top or bottom of
the vessel or receptacle A, and is provided at its lower end with apertures B¹ to
permit access of the oil or spirit to the wick C, which extends from the bottom of
a recess A¹ at the bottom of the receptacle A to the lower edge of a cap D firmly
secured in the upper end of the tube B. The interior of this cap D serves as a
vaporizing chamber. In the centre of the said cap is formed a small orifice D'
through which the vapour from the oil or spirit is projected into a tube E fitted
and secured upon the upper part of the tube B. The tube E is provided with
apertures E which are situated a short distance above the upper surface of the
cap D and whereby air enters to mix with the vapour. In the upper end of the
tube E is fitted, so that it is capable of vertical adjustment therein, the burner F
which consists of a metal tube provided at its upper end with a deflector comprising
a ring G of wire-netting or wire-gauze surmounted by a metal plate or disc H, for
the purpose of deflecting or spreading the flame.. Around the upper end of the
tube E is secured, by rivetting or in any other convenient manner, a bell-mouthed
collar J, so that by means of the sliding tube F, together with the said collar, the
supply of air to the exterior of the flame may be regulated or controlled.
K is a small bent tube contracted at its upper end and secured in the tube B
in such a manner that it connects the space above the liquid in the container. A
with the vaporizing chamber D. This tube K serves as a safety-valve to carry

described with reference to the accompanying drawing and operating as, and for
the purposes above specified.
