PROVISIONAL SPECIFICATION.
An Improved Device for Protecting Mantles of Incandescent
Gas Lamps.
I, FELIX EDWIN BATEMAN, of No. 119, Steelhouse Lane, in the City of Bir-
mingham, Gas Engineer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to an improved device for protecting the mantles of in-
candescent gas lamps and consists of a new or improved device for protecting
steadying and supporting the same.
"
My invention is applicable mainly to the new pattern "Welsbach" burner
without chimney, but is also applicable to any previous patterns of Welsbach
or other description of burner.
In accordance with my invention a metal ring grooved or otherwise is attached
to or slipped on to the burner. To this is fixed preferably by means of small
rivets a ring or band of thin sheet mica talc, or other heat proof and transparent
or semi-transparent substance. This is of a height about equal to its diameter
and is of a conical shape widening towards the top. The lower edge of the
mantle falls within this ring or band, and is thus steadied and protected, this
result being attained without diminishing the light.
In another form of my invention the metal ring carrying the mica or other
band is made as a fixture to the top part of the burner.
By these means the mantles of incandescent gas lamps, are steadied and pro-
tected in a better manner than by the methods hitherto in use.
Dated this 21st day of February 1899.
An Improved Device for Protecting Mantles of Incandescent
Gas Lamps:
I, FELIX EDWIN BATEMAN, of No. 119, Steelhouse Lane, City of Birmingham,
in the County of Warwick, Gas 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:.
-
This invention relates as hereinafter described to an improved device for pro-
tecting the mantles of incandescent gas lamps and is particularly applicable
to the new patterns of what is known as the Welsbach Kern" burner, such
burners being adapted for use without a chimney.
My said invention consists essentially of a device arranged to fit or to be

page_text: attached to such or other similar burners as aforesaid, whereby the mantle is
protected at its lower edge from violent draughts and also protected from injury
caused by vibration.
My invention will be more clearly understood by reference to the accompany-
ing drawings, in which the same letters of reference indicate similar parts
throughout.
Figures 1, 2, and 3, show a front elevation, a plan, and a vertical section
respectively of my invention. Figures 4 and 5 show the manner in which my
invention is applied to incandescent gas burners. A, represents a metal ring,
preferably of brass. B, is a cylinder made from a strip of mica or talc, con-
nected to the ring A, by the rivets D, or other similar fastenings.
The margin edges C, are connected together by the eyelets E, or by other
suitable fastenings. My invention is applied to a burner in the manner illus-
trated at Figure 4 (when such burner is used) by allowing the said device to
rest on or encircle the burner. In Figure 5, the said device is shown attached
to an ordinary pattern burner by means of the spring-like clips F, formed in
burner lead. My said invention may be applied to any form of incandescent
gas or other similar burner by any suitable form of attachment.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is―
1. In combination with incandescent gas burners the device composed of the
mica cylinder B, and the metal ring A, arranged substantially as herein des-
cribed and illustrated and for the purpose set forth..
Datel this 90th day of November 1899.
