Improvements in or relating to Lamps, Stoves, and the like, and to
Means for Supplying Oil or Combustible Fluid to the same.
We, LA SOCIETE GENERALE DES VERSEURS HERMETIQUES "L'EGIDE," of 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:-
This invention relates to a new device mechanically effecting without danger
the supply of lamps or stoves with spirit, petroleum or other inflammable liquid
said supply being effected without fear of spilling of the liquid and without com-
munication taking place between the outer air and the interior of the reservoir.
The invention is represented, by way of example, in the drawing accompanying
the present specification, in several applications for which it is adapted.
Fig. 1 shows the invention applied to an ordinary household lamp adapted to
be combined for the purpose desired with a receptacle Fig. 2 comprising the
mechanism required for that purpose.
Fig. 3 shows the invention applied to a table lamp mounted on a pillar the
interior of which forms a receptacle for the liquid, like the can or receptacle in
Fig. 2 and comprises the same mechanism as the latter, for working with the lamp
which it supports without necessitating its separation from it.
Fig. 5 shows the same device applied to a stove fed from a drum of large
capacity, which stove may be used and remain in connection with said drum or
be separated from it; similarly as a lamp or stove of smaller size could be com-
bined when in use with the receptacle Fig. 2 and remain connected to it and
separated only when said receptacle is emptied.
It is important to notice that the pillar lamp Fig. 3, could be fitted with the
filling device shown applied to the lamp in Fig. 1 preserving at the same time
the essential characteristics of the invention and could be combined either with
or
in Fig. 3 with an
the type of pillar constituting the reservoir as
ordinary pillar or support an inner reservoir in which case it would be com- -
bined for filling with a can or reservoir as shown in Fig. 2 like the lamp in Fig. 1
or with a device constituting a reservoir and comprising as shown in Fig. 4 the
same filling device as the lamp Fig. 1 applied to its base so that its filling can be
effected on the same principle as that of the lamp shown in combination with the
receptacle Fig. 2.
In all cases the liquid reservoir can A or pillar A¹ constituting the reservoir
comprises an upper part or socket B with a tube C extending nearly to the

page_text: bottom of the reservoir and having at its lower end, near the bottom an opening D
with a valve E opening under the pressure of the liquid into which it is inimersed;
within the tube Canother tube F' can reciprocate having a piston G at its lower end
provided with a central passage H open at the bottom and closed at the top by
a valve El opening upwards under pressure of the liquid under it in the tube C
when the tube F is depressed.
At its upper end the tube F is provided with a collar I with a screw-threaded
portion J at the top adapted to screw into the part K of a socket L secured to the
centre of the base of the lamp,. the collar having a central passage I forming
a continuation of the tube F.
The tube F may be combined simply with the collar I as in Fig. 3 the interior
of the lamp M communicating in this case directly with the interior of said tube F,
or the tube F may comprise as shown in Fig. 2, an elastic valve N at its upper end
and working in the same manner as the valve E¹ of the piston G and protected if
required by an ordinary or double perforated plate or netting O.
The socket L secured to the centre of the base of the lamp may be simply as
shown in Fig. 3 when the lamp M is not to be removed from its support for filling
said support then forming the reservoir or it may comprise as shown in Fig. 1
when the lamp M¹ is to be used independent of the filling reservoir a device with
a valve P which can be arranged and work exactly as the valve E¹ and N
mentioned before or as shown in Fig. 3 so that when the lamp M¹ is separated from
the reservoir or can A, said valve P automatically and hermetically closes
under the action of, say a spring PI as illustrated, the opening in the socket L
while when the lamp is placed on the reservoir for filling, the end of the screw-
threaded portion J of the collar I will push back the valve P the spring 1" being
compressed into its open position in which the interior of the lamp is placed in
communication with the interior of the tube F.
As has been stated before, the same device consisting of a socket L with a screw-
threaded portion K and valve P with a spring P can be applied as shown in Fig. 4
to the bottom of the reservoir A' formed in the pillar support of the lamp so as
to enable said reservoir to be filled in the same way and with the same advantages
as said lamp.
According to these arrangements the mechanical hermetic filling is effected as
follows:-
If the lamp to be filled is an ordinary lamp M¹ Fig. 1 it is secured by its
socket L to the collar I of the reservoir A, Fig. 2 and by means of said collar I
the tube F is raised in the tube C said raising producing the opening of the valve E
by the suction action on the liquid in the reservoir A and the rising of said liquid
in tube C below the piston G which of course rises with the tube F Then the
tube F is pressed downwards and its piston G pressing upon the liquid below it
in the tube C affects the closing of the valve E and the opening of the valve El
whereby the liquid passes from the tube C into the tube F through which it rises
into the socket L the valve of which is held open by the pressure of the screw-
threaded portion J of the collar I, and passes into the body of the lamp M¹ to be
filled. The raising and lowering of the tube F are repeated as many times as
required to cause a sufficient quantity of oil for filling the lamp to be pumped
through said tube F; the filling having been effected, the lamp M may be
separated from the collar I the screw-threaded portion J of which being unscrewed
enables the valve P in the base of the lamp to close again, while the valve N of the
tube F of the reservoir A closes said tube F. If the lamp to be filled is such as
is shown in Fig. 3 and mounted on a support A¹ Figs. 3 and 4 forming a reservoir
the filling of said lamp M is effected in the manner described so that in case,
say the lamp has to burn so long that the contents of the body of the lamp itself
are not sufficient it can be filled from the reserve supply contained in its sup-
porting reservoir A¹ by the same operation of the tube F as explained before; also
if this reservoir A' is supplied with a safety filling device in its base as shown in
Fig. 4 it will be understood that all these different filling manipulations both of

page_text: e lamp and of its reservoir can be effected easily quickly without danger
ithout fear of any escape of liquid.
The arrangement of the lamp Fig. 3 on a pillar or support forming a reservoir A¹
as the advantage of enabling a lamp M with a liquid receptacle of small capacity
nd containing a short wick to be used for a much longer time than ordinary
amps without necessitating the manipulations required by ordinary lamps the
apacity of which must be very large if it is desired not to have to fill them fre-
uently.
Moreover the combined arrangement as herein before described enables the lamp
o be charged without necessitating the extinction of the light.
The comparatively slight compression of air which may take place in the body
of the lamp during its filling by the means and operation described is easily
relieved either through the wick passage or through the slight looseness of the
screw-or other joint of the burner and the body said joint and passage being
sufficiently exact to ensure perfect working without however being sufficiently
air-tight to withstand a certain air compression in the body of the lamp.
It is evident that what has been just explained with regard to lamps is equally
applicable for stoves the liquid reservoir of which comprising the filling device
would then be combined like said lamp with
shown applied to the lamp. Fig.
a receptacle as A Fig. 2 so as to enable it to be filled under the same conditions
and by the same operations as previously described.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is;-
