AN IMPROVED DEVICE FOR THE BURNERS OF PARAFFIN OR OTHER VOLATILE OIL LAMPS APPLICABLE ALSO TO STOVES

do hereby declare the nature of my invention for "AN IMPROVED DEVICE FOR THE
BURNERS OF PARAFFIN OR OTHER VOLATILE OIL LAMPS APPLICABLE ALSO TO
STOVES " to be as follows, that is to say:-
My invention relates to that class of lamps in which paraffin and other volatile
oils are burnt and is for the purpose of producing a steady light and of securing
more perfect combustion and in consequence greater economy in the consumption
of oil.
In the construction of lamps such for instance as those shown in my Specification
No 433 A.D 1881 there are air holes around the base of the burner through which
the air freely circulates upwards and out at the top Now according to my present
invention I make a metallic cap which drops over outside the said burner covering
the said holes at the base in such a manner that the current is either wholly or
partly directed upwards to the neck or centre of the burner. So effective is this.
device that no chimney is required at all.
Where an outer case is used a rod or other equivalent may be connected to the
cap so that it can be lifted at pleasure and the lamp carried when closed without
fear of its being extinguished by the movement. Thus lamps for outside signal
posts may be lit at the lamp room and by lifting the cap by the rod they may be
carried a long distance with perfect safety to the signal post or station when the
cap is most simply placed in position and the lamp mounted into its position
Thus two conditions are fulfilled by my new device.

I WALTER HENRY BULPITT trading as Bulpitt & Sons of Camden Street
Birmingham in the County of Warwick. Lamp Manufacturer and Tin Plate Worker
do hereby declare the nature of the said invention for AN IMPROVED DEVICE FOR
THE BURNERS OF PARAFFIN OR OTHER VOLATILE OIL LAMPS APPLICABLE ALSO
TO STOVES and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement to be as follow that is
to say :-
My invention relates to that class of lamps in which paraffin and other Volatile
oils are burnt and is for the purpose of producing a steady light and for securing
more perfect combustion and in consequence greater economy in the consumption
of oil. In the construction of lamps such for instance as those shown in my
specification No 433 AD 1881 there are air holes around the base of the burner
through which the air freely circulates upwards and out at the top Now according
to my present invention I make a metallic cap which drops over outside the said
burner covering the said holes at the base in such a manner that the current is
either or wholly or partly directed upwards to the wick or centre of the burner so
effective is this device that no chimney is required at all.
Where an outer case is used a rod or other equivalent may be connected to the
cap so that it can be lifted at pleasure and the lamp carried when closed without
fear of being extinguished by the movement. Thus lamps for outside signal posts
may be lit at the lamp room and by lifting the cap by the rod they may be carried
a long distance with perfect safety to the signal post or station when the cap is
most simply placed in position and the lamp mounted into its position.
In order that my invention may be clearly understood and more easily carried
into practice I have appended hereunto a sheet of drawings upon which four views
are given of the application of my invention to a signal post lamp from which it
will be easy to apply the principle to various other lamps as well as to the lamps
used in stones.
Figure 1 is a part sectional elevation of a signal post lamp as it would be when
being carried by hand and before depositing it in its position.
Figure 2 is a part sectional elevation of the same lamp but taken at right angles
to Figure 1 and also as the lamps would be when burning on the signal post.
Figure 3 is also a part sectional elevation of the same lamp on the same line as
Figure 1 but showing the lamp in its condition for burning in the signal box.
Figure 4 is a sectional plan on line A B showing the supply air holes ccc
through which the air is drawn from the bottom of the lamp around the oil
reservoir as explained in my specification No 433 of
A.D. 1881 or in other
convenient manner.
Now it will be seen that the metallic cover or cap D is made to drop over the
burner E in such a manner as to cover the air holes c c c when the lamp is fixed in
position on the signal post The lamp is shown by Figures 2 and 3 in the position
for burning brilliantly ie the cover or cap D is down upon the plate F so that all
-

page_text: the air ascending through the holes ccc is conveyed and directed by the cap E
into the burner holes K thus increasing the brilliancy of the burning of the lamp
It will be noticed that the door or cover M in Figure 1 and 2 is open so as to allow
the heated air and products of combustion to pass away unhindered and thus
effected in the manner hereafter to be explained.
On reference to Figure 1 it will be noticed that the handle N is lifted into
a suitable position for carrying the lamp to the signal box or for moving it about
from place to place in the lamp room It will also be noticed that the door or
cover M is closed down and the cap or cover D is raised off the plate F so that any
air passing up through the hole cc has but little inducement to enter the burner
or to produce a fierce or brilliant flame indeed the practical effect produced by
closing the door M and lifting the cap D is that the draft of air is almost entirely
stopped. This is effected automatically by the movement of the handle N which is
hung upon the square ends of the double lever spindle P The short lever R is
connected to the rods 8 8¹ and the long lever T acts against the under side of the
cover or door M Thus when the short lever R is uppermost the rods 8 & 8¹ are
with the cap D lifted and the lid M is closed But when the handle N is turned
down the position shown by Figures 2 and 3 the long lever T is brought uppermost
and the door or lid M is lifted and the cap D is lowered It will be quite evident
that the means for raising the cap D and lid M may vary considerably without
departing from the nature of the invention.
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
(1) In paraffin or other volatile oil lamps or stoves a cap so constructed as to
direct the incoming air into a particular part or parts of the burner substantially
as and for the purpose herein set forth.
(2) In paraffin or other volatile oil lamps The cap D operated by the action of
the handle N so as to regulate the amount and direction of the incoming air
substantially as herein set forth.
