We EDMOND LAMBERT CONINCK and AUGUSTE ROLLAND both of Rue de l'Asile-
Popincourt, Paris in the Republic of France 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 Argand or circular burners capable of adaptation to the
body of a lamp for giving light by means of petroleum or other oils or essences.
It specially consists in the application to these burners:
1st of a false basket turning within a circular groove;
2nd of a ring soldered to this basket and carrying on its upper face epicycloidal
curves interrupted at the circumference and at the centre of the ring in which
engage the teeth of several pinions which act to raise or lower the wick within the
burner, without necessitating the use of a key or projecting spindle;
3rd of a soft metal support for the said pinions cast in one piece in a mould;
4th by the arrangement upon the ring of the glass holder or gallery, which is
moveable, of channels and, at the base of the wick holder of holes which permit
the excess of petroleum to flow into the interior of the lamp, in order to prevent as
much as possible the oozing of the same to the exterior.
The accompanying drawing represents our invention in all its details.
Figure 1 is a vertical section drawn on the axis of the burner.
Figure 2 is a plan.
Figure 3 is a top view of the soft metal piece supporting the pinions.
Figure 4 is an underside view of this support allowing a pinion to be seen in the
place it would occupy in the burner.
Figure 5 is a view of one of these pinions.
Figure 6 represents a plan view of the ring carrying epicycloidal grooves inter-
rupted at its circumference and at its centre.
.
Figure 7 represents the theoretical line of the epicycloidal curves.
The burner is furnished with the ordinary mounting or piedouche a for sealing
or only with a screw ring b capable of being soldered or otherwise fixed on the
body of a lamp. Above the mounting or piedouche is a base c soldered to the
burner and having its bead d milled so as to enable the burner which it supports
to be screwed onto the body of the lamp.

page_text: A ring e, carrying a flange or brim at its upper part and soldered at its lower
part to the base c forms with this latter the circular groove in which the basket f
turns, which is furnished with an inwardly projecting flange g which serves to
retain it between the ring e and the base c. The ring h carrying the epicycloidal
grooves is soldered to the interior of the basket. The teeth of the pinions i
partly engage in these grooves; the pinions are held in the position indicated at
Figure 1 by the support m furnished with recesses m¹ within which the pinions
turn, the axes of which work against this support which forms an inverted
bearing. Above the basket is the glass holder, which can be removed when
required; it is furnished with a grating n and with a friction tube o on the burner.
This friction tube carries on the interior, projections which alone are in direct
contact with the burner, and the spaces 8 left between these projections serve for
the flow of the petroleum which oozes around the burner.
The support m also carries projections and spaces & around the burner to
enable the excess of petroleum to run off which then passes through holes t formed
in the base of the burnet and falls into the lamp.
With a burner constructed in the above manner, if it is required to raise the
wick it is only necessary to turn the basket to the right, and to lower it, it is
turned to the left.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
1. The employment in Argand or circular burners without keys or projecting
spindles of a basket turning in a groove formed by the combination of the parts
constituting the same.
2. The employment for operating the pinions which raise or lower the wick of a
ring furnished with epicycloidal grooves interrupted at the circumference and at
the centre of the ring, thus enabling a rapid and regular action of the wick to be
obtained.
3. The employment of a soft metal support spaced to receive and hold the
pinions in contact with the ring h and the burner.
4. The moveable glass holder furnished with a friction tube o enabling the
excess of petroleum to flow along the length of the burner as above described and
represented in the accompanying drawing.
