A new method of constructing and manufacturing the above named Invention
by using for the purpose of acquiring strength, durability and great reduction in
cost, Cast Iron, Cast Iron made malleable, and Cast Iron made malleable in Com-
bination with Rolled Metals And also as hereafter further stated and shown, by
attached drawings and descriptions:

marked B K. Sheet 1. Fig: 2. Fige: 7. 8. 9. 28. and 29. represent the covering
of the Chimney in separate parts so cast and when constructed that all these parts.
are held firmly by means of one screw shewn Fig 28. Any kind of ornamental
top may affix in this manner. On the outside of the Chimney I cast four small
projections outside at right angles so that the rim, Fig 9, will fix itself on the
chimney and allow a passage at top and bottom for exit of the heated air from the
Chimney. Fig 7. shews a section of first top plate covering the Chimney with a
hole cast in the centre for the set screw to pass for fixing purposes. Fig: 8.

represents the same viewed as a disc from below. Fig: 29. represents a section of
second Covering or top covering with a pin or set screw in for fixing all these parts
together by a single set screw; these parts or covering of the chimney I make
ornamental or otherwise as required. Fig: 28 represents the pin for fixing the
parts together upon the Chimney of the Lamp shewn in Fig: 2.-Fig: 9. I cast
three small projections inside for the purpose of the edges of the cover (Fig: 29.)
to rest upon and bind the rim, Fig: 9, with the other covering of the chimney firmly
together; the projections on Fig: 29. are to bind Figs: 7 and 8. and secure a space
between them for the exit of the smoke from the chimney in order to allow a space
between the outside of the Cone and Chimney. Outside of the cone and chimney
I cast four small projections at right-angles so that these projections may hold the
rim Fig: 9 when affixed at equal distance round the chimney as shown Fig 2. and
the whole of this Fig: 2. bound round by the Letter B., with the exception of the
Handle (H), which I make of wood, and which is fixed at each end by a small
screw or pin to projections marked B H. that is the top, bottom, Chimney, two
sides of the Lamp with the Sockets on, and projections for the Handle I cast in one
piece and also the nipples to form the Hinges for the Door of the Lamp.-I cast
the end of the Lamp and the Door each prepared to contain the glass lens in two
parts as in Figs: 5 and 23. cone and rim part. as shewn in Fig 3.
Referring again to Fig. 5 I cast on nipples (A) to form the Hinges of the door
to affix to the Lamp. I also cast a projection to form a catch for the door to be
held when shut with a catch fixed on side of Lamp, this catch passes in a hole
in the projection of the door. Also a round hole marked C. for placing to the lens
and cone.
I also cast Fig: 23. and Fig: 5. with four small holes in (D) for the purpose of
attaching the cone and rim or rim and lens in its place. Fig: 23. shows the end of
the lamp I cast prepared for the fixing of the lens, rim or rim and cone as before
stated; and also with four flanges one at each corner at right-angles to the front
for the purpose of affixing the same to the sides of the lamp by rivits or small
screws at (A). Fig: 23.
Fig 3: Represents a Section of the Cone and rim with four small projections
thereon marked (A) these are for fixing to end of the Lamp and door by small
set screws. I cast this in one piece and fixed by the screws passing through the
holes marked D on the end and door of the Lamp Figs: 23. and 5.
Fig 4. represents a section of the end view of lens, cone and rim. I cast cone
and rim in one part or when no cone required I cast the rim and projections
together.
Fig: 24 represents the parts of the Lamp to contain the Oil and wick.-In
this I dispense with the usual mode of making them of tin plates and I also
dispence with the Screws as usually attached for putting in the oil and fixing the
wick by casting the body, top and bottom in one part and the necessary parts to
put in the oil together with the part for holding the wick. Fig: 26 shows the plan
of top of oil vessel bounded by the letter A, the letter B is the part where the oil
is put in the vessel.
I cover this with a moveable cover, working on a pin as shown Sheet No: 2
Fig 27. I also make a wire catch in the form shown Sheet No: 1. Fig: 33. one
end passes through the part (A) on Fig: 24 and then over the wick and thereby
fixed by means of the small thumb-screw shown Fig 34. which is screwed in the
top of the cistern marked B. The outside part of Fig: 26 represents plan of
Bottom of the Cistern with the holes Cast in to support combustion.
:
Fig 35, Sheet 2., represents a side view of the Section of a Lamp of the same
kind but specially adapted to be affixed by a projection from the bottom of the
Lamp I cast this in the manner described above with the addition of a projection
in place of the sockets for affixing the Lamp to the Carriages (a) being the
projection to fit into the Socket which is fixed on the Carriages.
Sheet 2. Fig 30. represents a portion of the pattern to make the sides, top and
bottom Cone, Chimney and handle which is attached by four small pins at each corner

page_text: at (a) to pattern for the bottom of the Lamp. And the parts marked B are core
prints for the sockets on the sides of the Lamp and of which no further explanation
is required to guide an Iron moulder in casting these parts.
Fig: 12 represents the top of an oil feeder which I make of cast malleable iron
and afterwards tin and for which I make a cover as before described and shewn
Sheet 2. Fig: 27, and Fig: 11. being a plan of the top. I also cast the bottom and
make it malleable and tin the same so that I can attach thereto strong rolled metal
sides or body as tin plates as shewn Fig: 10. the object being durability and lessen
the cost of production which by this means I accomplish.
Sheet No: 3. Fig: 1. represents a body of a Coach or Carriage Lamp to be affixed
to the Carriage by means of the socket (B.). this part of my new mode of construction
I cast, the top, one side and three corner posts together with socket and bottom of the
Lamp in one part or two parts as the design of the Lamp may require and mounting
the same with the door and end also cone rim and lens as previously set forth,
the Lamp part to hold the oil and wick shewn Fig 2 I cast in one part or two as
circumstances require. This Lamp is made for petroleum or other oils and to dispense
with any saldering as is usual. To hold the Lamp firm I cast a projection on part
marked (a) Fig 2 this part fits into a slot cast in part of the bottom of the Lamp at
the point marked (a) Fig 1. I also cast Fig 2. without bottom if the Lamp is required
for the use of Candles in the ordinary manner by putting a coiled spring in the
socket; in this case I affix the other side of the Lamp which being without bottom
a catch to pass through the part (c) Fig 1. and hole in (c) Fig 2. To hold the same
firmly down against the pressure of the spring. The top of this I also cast and
follow the same construction as previously described but vary as the designs and
ornamental purposes may require. I cast them and fix as before described.
Sheet No: 3. Fig: 3. represents a Street Lamp constructed in the same manner
ornamented as required and cast in as few parts as possible and Figs: 4. and 5.
represent two modes of casting the bars of the Lamp marked (a) Fig: 3 and on
which I put small strips of sheet copper, brass, or tin to hold the glass on the frame.
The door I affix in a similar manner as described before. I also construct Lamps for
the purpose of Heating, as oil Stoves as described Sheet 1. Fig 24. and base Fig 26.
In this case I adapt the size of the wick or wicks parts to the circumstances by
casting them in as few parts as possible, which I will further illustrate and describe
in my complete specification also the illustration of other kind of Lamps not herein
shown such as Roof Lamps for Railway Carriages, Ship Lamps and Hand Lamps
carrying the same invention and improved mode of Construction.
