A communication from abroad by CHARLES VAN GAEL of 147 Chaussée de Haecht
Schaerbeck in the Kingdom of Belgium.)
I FRANÇOLS HUBERT LENDERS of 118 Bishopsgate Street in the City of London
Merchant do hereby declare the nature of this invention to be as follows:-
In the specification of one Louis Cornelis No. 11,529 dated 24th August 1887 is
shown and described a lamp on which I have since applied for Patents for various
improvements.
My present invention relates to a further improvement upon same and consists in
placing inside of the perforated casing which surrounds the outer wick tube and which
supports the lamp chimney an annular metal ring preferably slightly curved at its
base.
This is secured in such a manner that the air from the outside of the lamp passing
through the perforations has a considerable travel around the outer wick tube before
reaching the outer edge of the flame. In this way the draught is steadied and
rendered more uniform to the manifest improvement of the light while its increased
travel assists in cooling the parts it surrounds.
I have also found that the cap or casing previously employed for covering the wick
spindles may be dispensed with, while the rack scabbard may be above the reservoir
into which the rack itself may pass.

I, FRANÇOIS HUBERT LENDERS of 118 Bishopsgate Street in the City of London,
Merchant, 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 :-
In the specification of one Louis Cornelis No. 11,529 dated 24th August 1887 is
shown and described a lamp on which I have since applied for patents for various
improvements.
To clearly explain the present invention reference is made to the accompanying
drawing in which :-
Fig. 1 is a sectional elevation of the perforated casing or "gallery" portion and of
the outer wick tube and wick raising device showing the improvements applied
thereto.
Fig. 2 is a plan of samo on the line z z of Fig. 1.
As a matter of convenience I have lottered the parts of same to correspond with
similar parts shown in the drawings forming part of my specification No. 2364 of 16th
February 1888, as the latter part of my present invention consists of a modification of
a portion of the wick raising device shown therein.
Inside the perforated casing or gallery portion H is secured to the part (from
which it depends) an annular metal ring W having an inward curve at its lower
part as shown. In this position it surrounds the outer wick tube D and causes
the air which passes through tho perforations of the gallery portion to take a
considerable travel around said tube, as shown by the arrows, before reaching the
outer edge of the flame, thus preventing any gusts of air from passing directly to
the flame and rendering uniform the draught, to the manifest improvement of the
light, while its increased travel assists in cooling the parts it surrounds.
The cap or casing which was lettered G, in the specification last above referred
to may be omitted, and the rack scabbard f may be made in the form of a casing
attached to the outside of the upper part of the wick tube D, and of such a
size as to cover the pinion d, instead of being below and dipping into the
reservoir.
The rack e travels in this by the operation of the pinion d and through the
thin metal arm e¹ which is attached to it, operates the toothed ring 9 which
engages with, and serves to raise and lower the wick. The purpose of this casing f
is to protect the rack and pinion from dust, and to prevent the oil from escaping
if the lamp is tilted over or upset.

page_text: Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
1. In a lamp a "gallery" portion having the annular air deflecting ring W,
substantially as described and for the purposes set forth.
2. In a lamp the combination with a pinion and rack for operating the wick-
raising device of a casing attached to the upper part of the wick tube to receive
the rack, substantially as described and for the purposes set forth.
Dated this 11th day of January 1889
