Improvements in Lamps or Lanterns.
I, CHARLES HARRISON MORTON, of Temple View, Burton Road, Derby, in the County
of Derby, Railway Official, do hereby declare the nature of this invention to be as
follows:
My invention has for its object the construction of a lamp or lantern suitable for use
on railway rolling stock or other travelling carriages or for ships port and starboard
and mast head lights cargo lights deck lamps and the like also applicable for stable
and general outside use.
This form of lamp or lantern is specially applicable to the now well known "Barton
Burner."
In my improved lamp or lantern I use a frame or body having preferably a central
air inlet at its bottom with a number of holes or orifices arranged in proximity
thereto.
To this bottom, and inside the lamp I hinge or pivot a perforated plate. Over this
plate and capable of sliding in suitable guides is another perforated plate carrying
the oil reservoir and the burner (for out door use advantageously of the "Barton" or
other petroleum type).
By the use of these superposed perforated plates a double air chamber or diffuser is
formed below the burner by which means strong up draughts are checked and perfect
combustion ensured.
On the top of the lamp or lantern I place a hood having at each end an orifice or
space for the escape of products of combustion and protected by another hood with
orifices at right angles to those in the first hood or I may provide a device to stop or
close the outlet opposite to the direction in which the vehicle is travelling.
By this means I prevent a front or back or side draught from putting out the
flame.
I prefer to use a double door formed by connected parallel plates to further decrease
the possibility of the flame being extinguished.

Improvements in Lamps or Lanterns.
I, CHARLES HARRISON MORTON, of Temple View, Burton Road, Derby, in the
County of Derby, Railway Official, 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 :--
My invention has for its object the construction of a lamp or lantern suitable for
use on railway rolling stock, or other travelling carriages, or for ships' port starboard,
and head lights, cargo lights, deck lamps, and the like, also applicable for stable and
general outside use.
This form of lamp or lantern is specially applicable to the now well known "Barton
Burnet."
Referring to the accompanying Drawings and to the figures and letters of reference
marked thereon.
Figure 1 is a section through a side light for railway rolling stock constructed
according to my invention

page_text: Figure 2 is a part section shewing an arrangement applicable to a head or tail
lamp for railway rolling stock.
Figure 3 is a plan of the bottom of the lamp on line a---b, the position of the
perforated hinged plate C being shewn in dotted lines.
In making my improved lamp or lantern I use a frame or body A having preferably
a central air inlet B at its bottom with a number of holes or orifices a arranged in
proximity thereto. The bottom of the lamp frame is dished or hollowed so as to form
an air chamber covered by a hinged or pivoted perforated plate C, or such plate
may work in grooves or be fixed.
Over this plate and capable of sliding in suitable guides is another perforated
plate D carrying the oil reservoir E and the burner F (preferably of the Barton or
other petroleum type); the perforations in all these plates being preferably non-
coincident.
By the use of these superposed perforated plates a double air chamber or diffuser
is formed below the burner by which means strong up draughts are prevented and
perfect combustion ensured.
On the top of the lamp or lantern I place a hood & having at one end an orifice
for escape of the products of combustion and protected by another hood H at right
angles to the first hood and with orifices at each end thereof; the end opposite to the
direction in which the vehicle is travelling is closed as shown in Figure 1 and the
other end provided with a flange I to further decrease down draught; or if desired
both ends of hood G may be left open as shown by dotted lines G' in Figure 1.
To prevent wind or rain extinguishing the light by coming through the crevices
of the door J I fix inside the lamp a baffle plate K. The door is provided with
another baffle plate L mounted on pins M as shewn in Figure 2, or I may use
instead of the baffle plate L an annular ring or rim N (Figure 1) provided with a
drip plate O for carrying off the water that may come in through the crevices of
the door.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
1. In a lamp or lantern for railway rolling stock or other outdoor use the employ-
ment of superposed perforated plates for the prevention of draught, substantially as
described.
2. In a lamp or lantern for railway rolling stock or other outdoor use the arrange-
ment of baffle plates, such as K L, substantially as described.
3. In a lamp or lantern for railway rolling stock or other outdoor use the employ-
ment of a door provided with an annular ring or rim N said ring being provided with
a suitable metal drip piece O for the deflection of water, substantially as described.
4. In combination with a lamp or lantern constructed as hereinbefore described,
a hood G having one of its ends closed and the other provided with a flange I
covered or crossed by another hood H having its orifices at right angles to the said
hood G substantially as described and illustrated.
5. The general arrangement and construction of lamps or lanterns for railway rolling
stock or other outdoor use and the combination of the severalparts thereof substantially
as hereinbefore described and illustrated by the accompanying sheet of drawings.
