Complete Specification Accepted, 1st June, 1889
I, HENRY CLAY WEBB of 74 Church Road Croydon in the County of Surrey,
Grocer, do hereby declare the nature of this invention to be as follows:-
This invention is an inconsumable wick for lamps. And, is intended, to be used
in conjunction with ordinary lamp wick as follows. An ordinary lamp wick is placed
in the burner tube of any lamp a short distance from the top of tube, the remaining
space in tube (and distance enough above the same to give the full power of lamp)
to be filled in with fibrous Asbestos or any other form of same, the wick to remain
stationary, and the power of light to be augmented or diminished by raising extra
outer tube, or lowering same. This applies more particularly to central air draught
lamps, to which this invention is applicable. In this case I propose to make the
inner tube as much longer as the wick is above the outer tube so that in raising the
extra outer tube to the level of inner tube it will extinguish the flame.

page_text: HENRY CLAY WEBB 74 Church Road Croydon Surroy Grocer 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 is an inconsumable wick for oil lamps, and, is intended to be used
in conjunction with ordinary lamp wick as follows, fibrous asbestos, or other form of
same, is woven the required thickness, and about one inch long, more or less, to fit
any lamp burner tube, and is securely fastened in same by being pinned through, or,
by indentations in tube, and being trimmed perfectly true both ends, enough wick is
left above the burner tube to give the full height or power of flaine without smoke,
ordinary lamp wick is introduced in tube in the ordinary way, and is turned up to
meet the asbestos wick, and acts as feeder to same, when it is desired to extinguish
the light, the feeder is turned down, and the wick and feeder being parted, the flow
ceases, and the asbestos wick is burned perfectly dry and clean effectually stopping all
sweating, an extra outer tube is fitted loose to each burner tube, to work
down, to regulate the flame, in the case of central air draught: lamps, to which this
up and
invention is particularly applicable, the inner tube is made as much longer, or higher,
as the wick is left above the outer tube, so that on raising the extra outer tube, it
will effectually control the flame, this disposition I claim to have the following
advantages, the wick being stationary it cannot be turned down into the oil chamber,
and is therefore a safety wick, being inconsumable, it requires no trimming, the flame
always remaining the same, cleanly, being burned dry and clean each time of lighting,
and the mode of parting the feeder from the wick and stopping the flow, thereby
preventing the sweating or overflow when not alight, giving a larger and whiter flame
than ordinary wick, asbestos-being-a-good-absorbent the wick can be fitted very tight
in burner tube, therefore, having greater thickness and consequently larger flame.
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. An inconsumable wick for oil lamne

page_text: 3. An arrangement of wick for oil lamps that will not impede capillary attraction,
and will at the same time be inconsumable viz. "short top wick."
4. A moveable extra outer tube to regulate the flame.
5. A perfect safety wick.
6. A stationary wick.
7. The arrangement of asbestos wick in conjunction with ordinary wick of making
the latter act as feeder to the former and parting the two to extinguish the flame and
burn the asbestos wick dry and clean.
