Improvements in Heating Attachments for Gas Burners and Lamps.
We CHARLES LONG, Mechanic, and ROBERT KARL SPROULE, Broker, both of
20 Wellington Street, East, in the City of Toronto, in the County of York, and
Province of Ontario, in the Dominion of Canada, 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:-
Our invention relates to that class of gas attachments used for heating purposes,
the object being to supply at small expense an adjustable beating attachment by the
use of which a cup or other small vessel may with its contents be heated over a
common or ordinary gas-burner.
With this end in view our invention consists of a frame or rest made of wire
interwoven together, preferably circular in shape and of suitable size, with two arms
extending downward and outward from the central portion of the said frame or rest,
as is hereinafter more fully described and claimed.
Figure 1 is a perspective view showing the device attached to a gas-burner ready
for use and
Fig. 2 is a sectional view of the same, taken on linea a of Fig. 1.
This attachment is composed of wire of a suitable size, as shown in the drawings.
A is the outer rim, preferably of circular shape.
B B indicate wires. These wires are secured at one end to the rim A, after which
they are carried inwardly in a horizontal plane to near the centre of the circle
formed by the rim A, from whence they are directed downwardly in a somewhat
curved manner, as shown, so as to fit over and clamp on the gas-burner.
D indicates a slide-ring placed exteriorly upon the clamping branches of the
wires B, and is designed to serve as a means for securing the attachment to a
burner. It is obvious that as the burner is of a tapering form by simply pressing
the ring downwardly it will clamp the branches upon the burner, while by sliding
the ring upwardly it will release the frictional contact between the burner and the
arms, and thereby permit the attachment to be readily removed, the outer ends of the
wires being secured to the rim at the points a.
E is a supporting-rim composed of a series of bowed or bant, wires, the ends of
which are attached to the rim or band A, so that their ends e may abut against each
other. By this construction it will be seen that when two wires are crowded
against each other and additional wires inserted the bowed or curved portions may
be carried to a greater altitude and the vessel sustained thereby raised from the
flame.
CC are the wire rods running crosswise from one side of the rim A to the other
side and nearly at right angles with and passing one turn around each wire of the
arms B B at 6, thereby strengthening the said arms. Each end of the rods C C is
securely attached to the rim A at cc, forming, in combination with the rim A and
arms BB, a strong frame or rest for the cup or vessel while heating. By this
means of construction I leave sufficient open or air space between the top of the
flame and the bottom of the vessel while heating to allow of the draught necessary to
prevent smoke.
The foregoing description is of the invention as applied to a gas-burner the same
is made applicable to lamp-chimneys by removing the sliding-ring D from the
clamping branches of the wires B. which when thus liberated and inserted into the
top of a lamp chimney has an outward pressure upon the inner walls of the said
chimney thereby causing a friction sufficient to hold the attachment securely in place
while in use, to remove the same you have only to lift it off as the friction caused

page_text: by the outward pressure of the clamping wires readily yield when the attachment
is raised.
While the description and drawings in this Specification indicate only an attach-
ment of circular shape, I do not confine myself to this particular shape in construction,
as any other desired shape may be made upon the same principle
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. A heating attachment for gas-burners, and lamps, composed of a circular rim, a
vessel-sustaining rim formed from bowed wires, with their ends abutting each other and
secured to the rim, the angular clamping-arms having one end attached to the rim and
being extended horizontally inward and bent downward whereby they are adapted to
embrace a gas-burner, the rods securing the horizontal branches of the clamping-
arms to the rim, and the ring on the clamping-arms for holding the same to the
burner, substantially as specified.
2. In a heating attachment for gas-burners and lamps the combination, with a
rim carrying suitable means for attachment to a burner, of a vessel-sustaining rim
composed of bowed wires having their ends secured to the rim and abutting against
each other, substantially as and for the purpose specified.
