Improvements in Lamp and Gas Chimneys or Globes.
We, ALBERT JOHN ALCOCK, ALFRED ALTHORPE SMITH, and ARTHUR HAINES, all
of Vancouver, British Columbia, Canada, Gentlemen, 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 :-
This invention relates to lamp and gas chimneys or globes, and it has for its object
to provide a new and useful chimney or globe of this character intended for use in
connection with an ordinary lamp or gas fixture for heating and cooking purposes, as
well as the ordinary purposes for which glass chimneys and globes are used.
With these and other objects in view which will readily appear as the nature of the
invention is better understood, the same consists in the novel construction, combination
and arrangement of parts hereinafter more fully described, illustrated and claimed.
In the drawings:-
•
Fig. 1 is a perspective view of a lamp and gas chimney or globe constructed in
accordance with this invention. Fig. 2 is a vertical sectional view thereof showing a
vessel supported thereon for the purpose of being heated.
Referring to the accompanying drawings, the numeral 1 designates a lamp and gas
chimney or globe provided at the top with a widened annular dished enlargement 2,
forming a widened supporting base providing for the support of tin or other suitable
light vessels which are placed on the chimney or globe for the purpose of being
heated. The enlarged supporting base 2 at the top of the chimney or globe is provided
at its edge with a peripheral series of vertically-disposed scallops comprising a regular
series of inverted U-shaped projections 3, and widened U-shaped heat escape spaces 4
alternating with the projections 3. When a vessel is placed on the enlarged supporting
base 2 at the top of the chimney or globe, it will be readily seen that the widened
heat escape spaces 4 permit the free escape of the gas and other products of
combustion and also allow for the free circulation of air so as to promote combustion
and insure the rapid and uniform heating of the vessel supported on the chimney or
globe.
The projections 3 form an even support for the vessel being heated while the
widened heat escape spaces 4 subserve the function stated, and thereby. obviate all
danger of an explosion within the chimney or globe, while a vessel is being heated,
which would be the necessary result of placing a vessel on top of an ordinary chimney
or globe.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what
we claim is
°
A lamp and gas chimney or globe for heating purposes provided at the top with a
widened annular dished supporting base for vessels to be heated, said supporting base
having at its edge a peripheral series of vertically-disposed scallops consisting of
regularly alternating projections and widened heat escape spaces, substantially as set
forth.
