Improvements in the Construction of Oil Lamps and Oil Stoves for
Lighting, Warming, and Cooking.
HENRY PATTMAN TRUEMAN of 3 St. Georges Terrace Hockley Birmingham in the
county of Warwick Engineer and Ironfounder do hereby declare the nature of this
invention to be as follows:-
The object of my invention is to simplify and cheapen the construction of lamps.
and lampstoves and relates to an improved method of constructing the burners,
chimnies, oil containers and connexion pieces to stands of lamps for lighting, and also
of the burners air passages oil-containers and seats of oil stoves, in combination or not
with ovens, or ornamental cases.
These present improvements relate specially to the
following well known portions of lamps and lamp stoves.
1st. The burner and air passages.
mode of constructing the
5th. Cases for heating.
In constructing the burner and air passages of a lamp or lamp stove according to
my invention, I form it of metal preferably of cast iron or brass in the following
manner.
One side of the body or plug and one side of the wick tube is cast in one piece, and
the remaining side with the wick winder cavity is cast in another piece, and these
pieces are afterwards united by any of the methods in common use for joining metal
work.
In some cases the plug of the burner is cast entire, with one half of the wick tube,
and the remaining parts added afterwards as before described.
The perforated air diffuser which is usually connected to the cone, or to the frame
supporting the cone, is according to my invention supported on extensions springing
from the wick tube itself. The cone and its connexions is made in one or more pieces
and placed so that it seats on a perforated plate laid upon the aforesaid extensions on
the wick tube.
The cone, chimney, and seat for cooking utensils, I prefer to form of two or more
separate castings which are connected to the plug, the oil container, or other suitable
support, by hinges which will allow the two castings being moved away from each
other at will. When these two castings are in their closed position, they form with
the aforesaid plug, tube-extensions, and perforated plate a complete burner, with air
passages and seat complete.
Being split or divided these two castings (forming practically the chimney of the
apparatus) can be opened out upon the aforedescribed hinges and free access is
given to the inner part of the apparatus for the purpose of trimming or replenishing.
The seat for cooking utensils is preferably formed with a trumpet shaped mouth for
the purpose of conserving the heat from the burner. This seat is omitted altogether
in lamps intended for lighting purposes only.
The portion of the chimney surrounding the flame is provided with transparent
apertures or windows.
When two or more burners are used conjointly, a central division is used, and
each side of such division is made into a complete air passage by a hinged corre-
sponding piece working up against it.
In constructing oil containers according to my invention I cast the hollow vessel
of two or more pieces and join them together. The vessels are afterwards rendered
perfectly oil tight by being coated either with a film of metal or vitreous enamel.

page_text: In constructing the connecting pieces (used to join oil containers to the stands or
brackets) according to my invention I form the portions engaging with the bottom
screw on the oil container in one casting and the lower portion which engages with
the stand or bracket is formed in a separate casting. These castings are afterwards
joined together by any well known means.
The forming of the article in separate pieces greatly facilitates its manufacture.
According to my invention I construct ovens for use in combination with oil
heating apparatus as follows.
The interior cavity of the oven is formed of a strip of sheet iron bent into a
suitable shape and joined by any well known means into a continuous band. The
width of this strip will be the depth of the oven from door to door. Another strip
of sheet iron of the same width (but so much longer that when joined up it shall
leave a space all round the smaller and inner band) forms the outer casing of the
oven.
The two bands are held apart and in proper position by two castings provided
with flanges adapted to engage with the outer and inner bands of sheet iron afore-
described. The castings are connected together by bolts, passing through the space
between the casings, or rivets are passed through the flanges and casings with or
without the aforesaid bolts.
One or both of the castings have apertures formed in them nearly as large as
the inner cavity, which said apertures can be closed by a door. Openings are made
in the outer casing for the ingress and egress of hot air currents, from the burners.
The burner or burners may be placed directly under the oven, or at the sides
thereof.
In some cases the outer casing is formed wholly or partly of cast iron plates with
suitable apertures for hot air currents, and the lamp burners are arranged round
the casing at the bottom or sides, with the chimney or air passages arranged to open
out on hinges and lugs as herein before described in connexion with my lamp stove
without an oven.
My improved ovens and oil tanks are also surrounded by non conducting materials,
when it is desired to prevent the conduction of heat.
According to this my invention I construct a case for heating purposes in con-
nexion with oil heating apparatus as follows.
I prefer to make the general form triangular in plan. Two of its sides are partly
composed of transparent materials while the third is formed of opaque or reflecting
materials.
If the form used should be square I make two adjacent sides transparent and two
adjacent sides opaque.
In some cases all the sides are transparent. This arrangement gives a large amount
of cheerful illumination for the space occupied.
The doors may be formed in any of the sides, but I prefer to make them in the
opaque sides and instead of hinging them cause them to slide vertically.

HENRY PATTMAN TRUEMAN 3 St. Georges Terrace Hockley Birmingham Engineer
and Ironfounder 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:-
The object of my invention is to simplify and cheapen the construction of lamps
and lamp stoves and relates to an improved method of constructing the various portions
relating thereto particularly the following.

UTACI
In constructing the burner and air passages of a lamp or lamp stove according to
my invention, I form it of metal preferably of cast iron or brass in the following
manner. One side of the body or plug and one side of the wick tube is cast in one
and the same piece and the remaining side is cast with the wick winder cavity in
another piece and these pieces are afterwards united by any method for such purpose.
In some cases the plug of the burner is cast entire with the one half of wick tube and
the remaining parts added afterwards as before set forth. The perforated air diffuser
which in ordinary cases is usually connected to the cone or to frame supporting the
cone is according to my invention supported on extensions coming from the wick tube
itself. The cone and its connections are made in one or more pieces and placed so
that its seats ou a perforated plate laid upon the aforesaid extensions on the said wick
tube. The cone chimney and seat for cooking utensils I prefer to form of two or
more separate castings which are connected to the plug, the oil container or other
suitable support by hinges which will allow the 2 castings being moved away from
each other at will. When these two castings are in their closed position they form
with the aforesaid plug, tube extensions and perforate plate a complete burner with
air passages and seat complete. Being split or divided these two castings (forming
practically the chimney of the apparatus) can be opened out upon the afore described
hinges and free access is given to the inner parts of the apparatus for the purpose
of trimming or replenishing. The seat for cooking utensils is preferably formed
with a trumpet shaped mouth for the purpose of conserving the heat from the
burner. This seat is omitted altogether in lamps intended for lighting purposes
only. The portion of the chimney surrounding the frame is provided with transparent
spaces or windows. When two or more burners are used conjointly a central
division is used and each side of such division is made into a complete air passage
by a hinged corresponding piece working up against it.
In constructing oil containers according to my invention I cast the hollow vessel
of two or more pieces and join them together. The vessels are afterwards rendered
perfectly oil tight by being coated either with a film of metal or vitreous enamel.
In constructing the connecting-pieces (used to join oil containers to the stand or
brackets) according to my invention I form the portion engaging with the bottom
screw on the oil container in one casting and the lower portion which engages
with the stand or bracket is formed in a complete casting. These castings are
afterwards joined together by any well known means. The forming of the article
in separate pieces greatly facilitates its manufacture.
I construct ovens for use in combination with oil heating apparatus as follows.
The interior cavity of the oven is formed of a strip of sheet iron bent into a
suitable shape and joined by any ordinary means into a continuous band. The
width of the strip will be the depth of the oven from door to door. Another strip
of sheet iron of same width (but so much longer that when joined up it shall
leave a space all round the smaller and inner band) forms the outer casing of the
oven. These two bands are held apart and in proper position by two castings
provided with flanges adapted to engage with the outer and inner band of sheet
iron afore described. The castings are connected together by bolts (or other means)
passing thro the space between the casings; or rivets are passed through the casings
with or without the aforesaid bolts. One or both of the castings have apertures
formed in them nearly as large as the inner cavity which said apertures can be
closed by a door, openings are made in the outer casing for the ingress and egress
of hot air current from the burners. The burner or burners may be placed directly
under the oven or at the side thereof. In some cases the outer casing is formed
wholly or partly of cast iron plates with suitable apertures for hot air currents
and the lamp burners are arranged round the casing at the bottom or sides with the

described in connection with my stove without an oven. My improved ovens and
oil tanks are also surrounded by non conducting material when it is desired to
prevent the conduction of heat. According to my invention I construct a case
for heating purposes in connection with oil heating apparatus as follows. I prefer
to make the general form triangular in plan two of its sides are partly of transparent
materials while the third is formed of opaque or reflecting materials. If the form
used should be square I make the two adjacent sides transparent and two adjacent
sides opaque. In some cases all the sides are transparent; this arrangement gives
a large amount of cheerful illumination for the space occupied.
The doors may be formed in any one of the sides, but I prefer to make them in the
opaque sides and instead of hinging them I prefer to construct them to slide in
grooves vertically.
In order that my invention may be fully understood and carried out I now refer
to the annexed drawings in which I show some of the methods in which I prefer my
invention to be carried out.
Fig. 1 is an end elevation of my plug and wick tube. Fig. 2 is a side elevation of
same. Fig. 3. is modification thereof. Fig. 4. is a plan of Fig. 1. Figs. 5 & 6 show
the internal construction of my wick tube by seperating same along line A B. Fig. 7
shows end elevation of my wick tube in which I dispense with the screw thread on the
plug. This burner is oblong in shape and is used in the drawings in conjunction with
iny stoves instead of the round shape as shown in Fig. 1, 2, & 3. Fig. 8 is a side
elevation of same. Fig. 9 is a plan of same. Fig. 10 is a side elevation of a lamp
stove. Fig. 11 view of same partly in section through line c. y. and elevation. Fig. 12.

elevation of a modification of fig. 13. Fig. 15 further modification. The line of
division in this case being at right angles to the burners instead of parallel to. same.
Fig. 16 plan of same. Fig. 17 still further modification in which the chimneys open
out horizontally along line z. Fig. 17 or any other suitable place. Fig. 18 is a plan
of same. Figs. 19 and 20 show methods of constructing oil tanks. Fig. 21 cross

structed according to my invention. Fig. 25. central longitudinal section of same
(that is from back to front).
Referring now to Fig. 1. I construct the plug and wick tube of a lamp burner by
casting the parts situated to the right of the line A. B in one piece said parts as
follows e plug, d collar, e wick winder cavity, f wick tube extensions g, side of wick
tube and h cap to wick winder bearing. These two castings are united by any well
known means and when held in juxtaposition as shewn in the drawing form a wick
tube and plug for a lamp burner. When this burner is in use a perforated plate i is
laid upon the extensions f, and upon this plate, or the extensions the cones of the
chimney rest as shewn in Fig. 11. and thus take a bearing. In Fig. 3 a modification
is shewn in which the plug c is cast solid with either the right or left hand parts,
which said parts are attached afterwards in the usual way. The passage Figs. 1 & 3.
is cored out in the casting, or it may be drilled or slotted. Fig. 4. shows plan of
Fig. 1. Fig. 5. shows internal construction of left hand side of wick tube. Fig. 6
shows internal construction of right hand side of wick tube and burner. Fig. 7. end
elevation of a wick tube and burner in which the screw thread is dispensed with. The
plain plug is dropped into an opening in the oil tank as shown in fig. 11.
Fig. 8. is

oil stove, burner e one of the hinged chimneys 1, hinged at q. q. mica or tale plate t
retained in position by metal clips t', t, t, t, this opening may be made in both
chimneys. The chimneys may be made of stamped metal such as sheet iron or they
may be made in several pieces joined together; the said chimneys, (Fig. 11.) are
held in the closed position by their own weight and the weight of any article placed
upon the top, but I prefer to detachably connect them by books or bolts or catches

page_text: such as shown in Fig. 12. in which a catch is shown o, o' knob and lever working.
upon pin n. This pin n. is secured to the piece p' which is attached to the left hand
chimney p², a small stop, p affixed to the right hand chimney p³ engages with the knob
and lover o, o', when the same is depressed. The stop p projects a sufficient distance
to afford a secure fastening. Fig. 11. shows view of oil stove partly in elevation and

Fig. 14 further modification partly in elevation and partly in section in which a
central bar s. acts as a deflector and forms two chimneys this bar may be supported at
its ends by carrying projections engaging with corresponding notches in the ends of
the chimneys. Fig. 15 shows another modification in which the chimneys which are
double are placed so that the dividing line is at right angles to the burners instead of
being parallel with same, the burners being one behind the other, the products of
combustion passing up two separate chimneys as shown at el, e², Fig. 16, which is a.
plan of same. A still further modification of construction is shown in Fig. 17. in side.

tudinally on line v³, v, Fig. 18 which is a plan of sanie. The chimneys are provided
with knuckle hinges or their equivalent v, v' and can be sucured by any suitable
means at when closed such as the catch already described. The chimneys can be
opened out on the hinge at in a horizontal direction by being separated along.
line z. z, Fig. 17 or other convenient part. Fig. 19 shows in section my improved
method of constructing oil vessels for lamps in cast iron. The upper part w and
the lower part w² are cast separately, the parts w and w¹ are afterwards held,.
joined or rivetted at w², together and the vessel is then made oil tight by coating the
joint with a film of metal which fuses at a lower heat than cast iron. The shape
of the vessel may be varied to suit the purpose for which it is designed. I am
aware that sheet metal vessels are commonly made in two pieces, and afterwards.
soldered together, also that cast metal oil tanks have been made in two pieces and
afterwards screwed or jointed together with cement.
Fig. 20 shows a section of a connecting piece which is cast in two parts w² and w³.
as shown.
These parts are afterwards connected by any well known means, the
part 2 if required with an internal thread, it can readily be manufactured before.
being fixed to, and considerable economy is effected in labour and material.
Fig. 21, shows in cross section my construction of a small radiator or heating
case.
The top ends, sides and handles are formed of two castings 1, 1, the two
halves are united by bolts, screws rivets or catches, the rivet 3 passes through
the handle at the top, or other suitable part of the apparatus. Fig. 22 side

of sheet iron folded or otherwise joined into a continuous strip. 6 is an outer band
of the same, leaving the air space between the two bands. 11. plate (preferably of cast
iron) slightly larger than the largest band of sheet iron when folded to an oblong circular
or square shape. This plate is forined with ribs or flanges 8, 9, 10, a similar plate, but
with central aperture 12 for doorway has also flanges, 8, 9, 10. These flanges, 8, 9, 10,
engage with and hold the bands 7, 8 in position as shown in Fig. 25; bolts 5 pass
through the air space and hold the plates 11, & 11', in position. The doorway 12 on 11' is
closed by the usual door on hinges. Apertures 15 are formed in the band 6 as shown
for the purpose of allowing the hot air from the burners to circulate around band 7.
The outer case according to my invention is sometimes encased in non conducting
material such as asbestos or sand.
In the annexed drawings of my stove the arrows show the direction in which
the chimneys open on the hinges g.
Similar letters of reference refer to similar
arts
