PROVISIONAL SPECIFICATION.
An Improvement in Domes of Oil Lamps for Supplying Rarefied
Air to the Flame.
1, HENRY SALSBURY, of 125 and 126 Long Acre, London, Lamp Manu-
facturer, do hereby declare the nature of this invention to be as follows:-
This invention has for object, improving the luminosity of the flame of an oil
lamp by making the dome of such shape and in perforating the bottom plate as
well as the upper surface near the rim, that the entry air entering by such holes
takes up heat from the wick tube and from the dome while in transit, as to issue
from an annular or other recess into direct con tact with the flame, which flame is
not only enriched thereby but burns more steadily and is free from smoke.
The neck of the dome may be split or be corrugated for increasing the air
passages.
The invention is chiefly intended for socket lamps such as are used with road.
vehicles.

An Improvement in Domes of Oil Lamps for Supplying Rarefied
Air to the Flame.
I, HENRY SALSBURY, of 125 and 126 Long Acre, London, Lamp Manu-.
facturer, 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 :-
This invention has for object, improving the luminosity of the flame of an oil
lamp by making the dome of such shape and in perforating the bottom plate as
well as the upper surface near the rim that the entry air entering by such holes
takes up heat from the wick tube and from the dome while in transit as to issue
from an annular or other recess into direct contact with the flame, which flame is.
not only enriched thereby but burns more steadily and is free from smoke. The
neck of the dome may be split or be corrugated for increasing the air passages.
The invention is chiefly intended for socket lamps such as are used with road.
vehicles.
My invention is clearly represented in the annexed drawings.

page_text: A, cap. B, base. C, neck, which is preferably in two pieces and look in opposite
directions, the two being clamped as one by the rim D of the cap or dome A.
The neck may be part of the wick tube or as sleeve outside a wick tube both disc
and dome being perforated or otherwise formed with air passages to feed the
flame and increase its luminosity by the concentration and inward deflection, the
heat generated by contact in passing through the dome rendering such air
rarefied and more suitable for combustion and producing increase of light, said air
issuing from an annular or other aperture into direct contact with the flame.
Having now particularly described and ascertained the nature of this inven-
tion and in what manuer the same is to be performed I declare that what I
claim is:
1. The improvement in domes for oil lamps, as described for the purpose set
forth.
2. Constructing domes for oil lamps of two perforated discs with necks inverted
and clamped within the rim near which are other perforations as shown on the
annexed drawings for the purpose described.
