PROVISIONAL SPECIFICATION.
Improvements in or connected with Incandescent Gas Lamps.
I, JOSEPH CARTER, Clarence Villa, New Bisley Road, Stroud, Gloucestershire,
Machinist, do hereby declare the nature of this invention to be as follows:-
-
An appliance made of metal and hollowed up so as to surround the mantle at its
bottom end and also made adjustable by an inner tube to raise or lower according to
length of mantle, this tube fitting tightly on the incandescent gas light burner.
The exclusion of cold air on the mantle preventing unequal contraction of
mantle. In case a mantle should be broken the gas is so controlled by the par-
ticular shape of the appliance that it cannot strike the chimney. Therefore
protecting mantles and chimneys.

improvements in or connected with Incandescent Gas Lamps.
I, JOSEPH CARTER, of Clarence Villa, New Bisley Road, Stroud, in the County
of Gloucestershire, Machinist, do hereby declare the nature of this invention, and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:
-
My invention relates to improvements in or connected with incandescent gas
lamps, which consists of an appliance made of metal and hollowed up so as to
surround the mantle at its bottom end, and also made adjustable by an inner
tube to raise or lower according to length of mantle, this tube fitting tightly on the
incandescent gas light burner.
The exclusion of cold air on the mantle prevents unequal contraction. In case a
mantle should be broken the gas is so controlled by the particular shape of the
appliance that it cannot strike the chimney, therefore protecting mantles and
chimneys.
And in order that my invention may be thoroughly understood, I now proceed to
describe the accompanying drawing thereof, reference being had to letters .and
figures marked thereon.
Fig. 1, is the apparatus shown half in section and half in elevation.
Fig. 2, is a plan of the sliding hollow cup to surround the mantle.
Fig. 3, is a section on line A, B, of Fig. 2.
In carrying my invention into practice I provide a ring a with a number of
slits b cut in the said ring. At or near the base of the ring a I fix a hollow circular

page_text: cup c, thus forming a hollow cup so as to surround the mantle d at its base. The
aforesaid apparatus slides up or down on the burner e as indicated in dotted lines in
Fig. 1, and may be placed in any position suitable for any length mantle.
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. In incandescent gas lamps, the combination of the sliding ring a slits 6 and
hollow cup c fitted to a gas burner to surround the base of a mantle, substantially
as herein described and according to the accompanying drawing.
2. In incandescent gas burners, the combination of the various parts substantially
as above described in this specification and illustrated in the drawing.
3. In incandescent gas burners, the sliding apparatus for surrounding the bases
of mantles of various lengths, substantially as described. .
