page_text: We WOLF DEFRIES, of 4 Cleveland Gardens, London, Gentleman, and VICTOR
ISIDORE FEENY, of 7 Queen Victoria Street, London, Consulting Engineer, do
hereby declare the nature of this invention to be as follows:-
Our invention relates to a novel construction of lamp burner, in which the
cbimney holder can be more readily raised and lowered than is possible in existing
constructions, and in which the use of separate guide rods, as at present employed, is
entirely dispensed with. In carrying out our invention we propose to attach to, or
form upon, the cylindrical burner-tube one or more vertical projections or grooves on,
or into, which a collar, having corresponding grooves or projections, is free to rise
and fall. To this collar are attached two or more rigid arms upon which the chimney
holder is secured. The arms project through suitable helical slots formed in a sleeve
which encloses the sliding collar. When by means of a lever or otherwise the sleeve
is rotated round a vertical axis, the collar is caused to move in a vertical direction,
carrying with it the chimney holder.
For the Applicants,
W. E. GEDGE,
Agent.

We, WOLF DEFRIES, of 4 Cleveland Gardens, London, Gentleman, and VICTOR
ISIDORE FEENY, of 7 Queen Victoria Street London E.C., Consulting 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:-
Our invention relates to a novel construction of lamp-burner in which the chimney
holder can be more readily raised and lowered than is possible in existing construc-
tions, and in which the use of separate guide rods or other independent guides as at
present employed for this purpose is entirely dispensed with; an important feature of
our invention being the utilization of the burner tube as a guide for the raising and
lowering; we also make the chimney holder readily detachable for the purpose of
cleaning and trimming the lamp, and the whole arrangement is entirely independent
of the body of the lamp.
On the accompanying sheet of Drawings
Fig. 1. is a vertical section through a round burner embodying our invention.
Fig. 2. is a similar view showing the chimney holder raised for the purpose of
lighting..
Fig. 3. is a similar view showing the chimney holder removed for cleaning; and
Fig. 4 is a horizontal section on line 1-2 in Fig. 1.
In order to carry out our invention we attach to or form upon the cylindrical.
burner tube A one or more vertical ribs a, on which a collar B having a corresponding
groove or corresponding grooves into which the rib or ribs a fit, is free to rise and
fall.
To this collar are attached two or more rigid arms C on to which is fixed a hori-
zontal ring D furnished with one or more cheeseheaded studs d engaging in one or
more slotted and enlarged openings e formed in the flange E which carries the
chimney.
The arms C project through helical slots f formed in a sleeve F which encloses the
sliding collar B. The sleeve F is provided at its lower end with a horizontal projection
or flan H which is prevented from rising by means of a suitable projection K
preferably formed round the lower part of the chimney holder. The projection H or
horizontal tongue attached to the flange extends through and works in a slot formed
in the lower part of the chimney holder, and may be furnished at its extremity with
a knob G. When by means of the knob G or otherwise the sleeve F is rotated the
collar B is caused by the rib or ribs a to move in a vertical direction carrying with it
the arms C which support the gallery. When it it is required to remove the upper
part E of the chimney holder for the purpose of cleaning or trimming it is turned till
the studs & come opposite enlargements of the slots e in the flange E.
In lieu of the ribs a on the burner-tube A we may form vertical grooves in which
corresponding projections on the collar B will work. We may dispense with the
ring D, attaching the arms C directly to the flange E.

page_text: 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. In a round lamp-burner the vertical ribs or grooves a in combination with the
collar B furnished with corresponding grooves or projections and carrying the arms C
for the purposes and substantially as described.
2. The ring D furnished with the studs d in combination with the slotted and
enlarged openings e for the purposes and substantially as described.
3. A round Lamp-burner constructed, combined, and arranged to operate substan-
tially as described and illustrated on the accompanying sheet of Drawings.
Dated this Thirteenth day of March 1889.
