Improvements in and relating to Lamp Burners.
I, ALFRED DECAMPS, of 2, Passage St. Sébastien, Paris, France, Manufacturer,
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 has for object a new system of opening and closing lamps which
is applicable to lamps which would be constructed in future according to this
system, and also to lamps which are already constructed and in use.
It is known that in all lamps using liquids for combustion, or even gases as
in the recent lamps for burning acetylene, it is almost always necessary to un-
screw the burner from the body of the lamp, in order to refill the lamp with liquid.
In this operation the hands of the operator are greatly embarrassed, and there is
a risk of spilling the liquid outside of the lamp, either in the manipulation of
the filling can or vessel or by the wick of the burner which drips outside the
lamp reservoir.
Now with the new system of invertable burner, and tipping dish hereinafter
described, the burner is not required to be detached from the lamp, but can be
inverted by a simple operation so as to leave the two hands free to pour out the
liquid of which not a drop can be lost, thanks to the arrangement of a fixed dish
which fills the office of a funnel.
By way of evample, and in order to clearly describe the invention, two methods
of closing, namely by means of a screw and by means of a bayonet joint have
been shown in the accompanying drawings. Figure 1 shows a petroleum burner
mounted on a movable dish screwed on to a lamp body with screw closure.
Figure 2 shows the same burner inverted to allow of filling the lamp. Figure 3
is a plan of the burner shown in Figure 1. Figure 4 shows a tipping dish with
a bayonet joint closure. Figure 5 shows the dish, the burner being tipped or
inverted. Figure 6 is a front elevation of Figure 5. Figure 7 shows the dish
in plan view. In Figure 1, A indicates the socket of the body of the lamp, B
the burner, C the dish, D the hinge, E the tipping socket, which enters with
slight friction into the central opening of the dish C. F is the closing screw.
In Figures 2 and 3 the same letters indicate the same parts.
The operation of this tipping arrangement is self-evident, and is obvious from
an inspection of the drawing. It will be seen that this method of closing is
very efficient, and that the screw which bears and makes a tight joint upon a
rounded portion, forces the burner suitably upon the dish.
In Figure 4 A represents the tipping dish which screws upon the body of an
ordinary lamp. B is the tipping socket, b the bayonet joint groove, C the burner,
D the hinge having a sidewise movement, and E is the closing knob which engage
in the groove of the bayonet joint.
In Figures 5, 6 and 7 the same letters indicate the same parts. The opera-
tion, which is very simple, will be readily understood by inspection of Figures 6
and 7. It will be seen in Figure 6 that the female part of the hinge D is
adapted to turn circularly upon the male part, which is rivetted to the dish A.

page_text: On turning down the tipping socket, as is shown in Figure 7, the notch b of
the groove engages with the knob E, and if a circular movement be imparted to
the burner in the direction of the arrow (Figure 7), the knob will engage with
the groove of the bayonet joint and the lamp will be closed hermetically. The
groove 6 is in an inclined plane, so as to produce a hermetic closure of the tipping
socket B upon the dish A.
I reserve the right of modifying the shape and nature of these hinges and in-
stead of which I may employ a spring, or a catch sliding in a slide; said hinges
having any desired number of attachments to the dish and tipping socket, I am
able to arrange the screw and the knob at various points, or I may employ a
greater number thereof.
I reserve the right of constructing this apparatus in all sizes, and in all metals,
with any modifications of shape to suit the burners to which the said apparatus
is to be applied, without thereby departing from the nature of the invention
which I claim.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manuer the same is to be performed, I declare that what I
claim is:-
-
In lamps for combustible liquids or using liquids such as acetylene lamps,
the principle of the tipping of the burner which remains attached to the body
of the lamp with the object of facilitating the operation of filling. This tipping
or inverting being effected by means of the herein above described methods either
through the medium of a dish screwing upon the body of the lamp and carrying
the tipping socket upon which the burner is screwed; this arrangement is applic-
able to existing lamps, for instance by applying the same hereindescribed methods
directly to the burner and to the body of the lamp.
The closure and the tipping movement is effected by means of an ordinary
hinge as shown in Figures 1, 2 and 3 and by means of a screw, or by means of
a sliding hinge and a knob adapted to engage in a slot or groove arranged in an
inclined plane as shown in Figure 4 and the following figures.
The whole substantially as hercinbefore described, for the purpose specified,
with reference to the accompanying drawings.
