IMPROVEMENTS IN LAMPS
Year: 1884

page_text: I PAUL AMBROSE BAYLE of 37 rue de Naple Paris Engineer do hereby declare
the nature of my invention for "IMPROVEMENTS IN LAMPS" to be as follows:-
The object of this invention is to so construct a lamp as always to present a
constant steady level of liquid to the wick of the burner.
The lamp consists of two main parts a reservoir and a burner the former which
contains whatever liquid is to be burnt and which may be of any form, round
square or otherwise, and is traversed from top to bottom by a small fixed tube
open at its upper and shut at its lower end where it rests on the bottom of the
reservoir. This I call the tube of distribution.
At a suitable distance from the base of this tube and at right angles to it, is
soldered a second tube which passes out through the side of the reservoir and
supports the burner. I call this the feeding tube. Opposite the junction of the
two tubes a hole is pierced in the tube of distribution, whereby the liquid
contained in the reservoir may penetrate into the feeding tube and thence to the
burner.
Inside the tube of distribution which traverses the reservoir from top to bottom
is another that can be slidden up and down and which acts as an obturator or
closing apparatus. By pushing it down to the very bottom of the tube of
distribution the hole whereby the liquid passes into the tube, is stopped and the
feeding ceases while by withdrawing it, the aperture is uncovered and the
feeding process goes on.
On the top of the reservoir is an opening closed with a screw cover for filling
the lamp
The burner consists of a hollow bottom piece through which passes a fixed
vertical open tube-the interior current of air to be supplied to the interior of the
cylindrical flame rises up through this tube. Over this slides another moveable
tube which carries the wicks.
Between this latter and the inside of the bottom piece is placed a third tube
soldered at its lower end to the bottom of the bottom piece. Its upper end projects
above the bottom piece and has a screw thread cut around it, on to this is screwed
a tubular top piece which surrounds the upper ends of the other tubes and forms
the upper part of the burner, The above mentioned third tube is pierced with a

which encloses all the other tubes and forms the upper part of the burner-The
wick tube carries two wicks-one termed the feeding wick which remains around
the bottom part of the tube and above this another wick which is the burning
wick and should be renewed every day.
When the obturator tube is withdrawn the liquid runs into the feeding tube,
through the aperture alluded to above, enters the bottom of the burner, meets the
tube with the circle of holes to the feeding wick and passes on, by capillary
attraction to the burning wick. A level is thus established between the burner
and the tube of distribution at the height of the aperture made opposite to the
joint of the feeding tube.

page_text: I PAUL AMBROSE BAYLE of 37 rue de Naples Paris Engineer do hereby declare
the nature of my invention for "IMPROVEMENTS IN LAMPS" and in what manner
the same is to be performed to be particularly described and ascertained' in and
by the following statement:-.
The main object of this invention is to so construct a lamp as always to present
a constant steady level of liquid to the wick of the burner.
In the drawing hereunto annexed I have shewn two examples of lamps
constructed according to my Invention. Figure 1 is vertical section of a lamp
suitable for burning mineral oil and Figure 2 is a vertical section of a lamp suitable
for burning vegetable oil.
Each lamp consists of two main parts a reservoir and a-burner. The former
marked A contains the supply of liquid to be burnt and may be of any form round
square.or otherwise; the latter marked B contains the wick and is constructed as
liereinafter described. The reservoir A is traversed from top to bottom by a small
fixed tube C open at its upper end and shut at its lower end where it rests on the
bottom of the reservoir. This I call the tube of distribution.
At a suitable distance from the base of this tube and at right angles to it is.
soldered a second tube D which passes out through the side of the reservoir and
supports the burner B.
This I call the feeding tube.
Opposite to the junction of the tubes C and D a hole O is pierced in the tube C
whereby the liquid contained in the reservoir may penetrate into the feeding
tube D and thence to the burner.
Inside the tube C is another tube E that can be moved up and down within it.
it is shewn to have a screw thread cut upon its upper end to screw into a corre-
sponding screw thread in the interior of the upper part of the tube C so that it
may be raised or lowered by turning it by its milled head E¹. When the tube E
is lowered it more or less closes the hole O and arrests all flow of liquid to the
burner. When the tube is raised the aperture O is uncovered and the feeding
process goes on and maintains the liquid in the burner at the same level as the
aperture O.
On the top of the reservoir is an opening closed with a screw cover G for filling
the reservoir.
The burner consists of a hollow bottom piece H through which passes a fixed
vertical open ended tube I. The interior current of air to be supplied to the
interior of the cylindrical flame rises up through this tube.
Over the tube I slides another movable tube K which carries the wicks.
Outside the tube K is a third tube L soldered at its lower end to the bottom of
the bottom piece H whilst its upper end projects above the top of the top piece
and has a screw thread cut around it on to which is screwed a tubular top piece M
which forms the exterior of the upper part of the burner.
The feeding tube D may either supply liquid to the interior of the bottom.
piece H from whence it may pass through holes in the tube L to the wick, or the
feeding tube D may supply the liquid directly to the interior of the tube Lin
which case the piece H would simply form an ornamental covering to the lower
part of the burner. The tube L also need not in all cases be carried down to the
bottom of the piece H but may simply be carried upwards from the top of this
piece as shewn at Figure 2.

page_text: In the lamp shown at Figure 1 the wick tube carries two wicks one termed the
feeding wick marked N which remains around the bottom part of the tube and
above this another wick P which is the burning wick. These wicks are shewn at
Figure 3.
The wick tube K is shewn separately at Figure 4 it can be raised or lowered by
a pinion working into a toothed rack fast upon it.
The hollow bottom pièce H is shewn separately at Figure 5 and the tubular top
piece M of the burner is shewn at Figure 6.
When vegetable oils are to be burned the feeding wick is done away with and
the burning wick only employed. The wick is carried on the exterior of a common
wick tube which has a lifting rack fixed to it in the ordinary manner-a separate
view of the wick tube and rack is shewn at Figure 7.
.
In this lamp also the top piece M may be suppressed and the tube L which I
have called the third tube be continued straight all the way up.
In both lamps whether for mineral or vegetable oils a cup Qis screwed on to the
lower extremity of the tube L-the upper part of this cup is perforated to admit
air to the lower end of the tube I.
The chimney glass holder R is made in the ordinary way except that I some-
times partially close the under surface leaving only a circlet of holes to allow
passage for air.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
First. The construction and arrangement of the reservoir with its feeding and
obturator tubes CD and E as above described.
Second. The construction and arrangement of the burner with its third tube L
through which the oil reaches the wick from the feeding tube.
Third. In the case of mineral oil lamps the division of the exterior tube of the
burner into two parts screwed the one on to the other to enable the burning wick
to be easily removed.
Fourth. The construction of lamps substantially, as hereinbefore described and
illustrated in the drawing annexed.
