page_text: LETTERS PATENT to Richard Schreiber, of Red Cross Street, in the City of
London, Lamp Manufacturer, for the Invention of "IMPROVEMENTS IN AND
CONNECTED WITH BURNERS FOR PARAFFIN AND SIMILAR MINERAL OIL
T.AMIDE"
Sealed the 23rd February 1877, and dated the 1st September 1876.
PROVISIONAL SPECIFICATION left by the said Richard Schreiber at the Office
of the Commissioners of Patents on the 1st September 1876.
RICHARD SCHREIBER, of Red Cross Street, in the City of London, Lamp Manu-
facturer. "IMPROVEMENTS IN AND CONNECTED WITH BURNERS FOR PARAFFIN
AND SIMILAR MINERAL OIL LAMPS."
This Invention relates to improvements in and connected with burners for paraffin
and similar mineral oil lamps, and consists in forming a double slit or a circular slit
with partitions or division plates in the bottom plate of the burner that two ends
of a flat tape or web of the usual cotton can be pushed into them, and be raised as
desired by wheel or other appliances fitted within the barrel portion.
Above the bottom plate is a parallel tube, with a clear space or chamber at the
bottom of it; this tube carries the tape or web forming the wick. Surrounding
this parallel tube is a tapered tube, with two or more Vor other shaped apertures
formed in it above where the division plates are arranged in the base plate that air
may enter to the interior of the inner or parallel tube to support combustion from
the interior, and to improve the brilliancy of the light, also to keep the burner
cool.
The V apertures of the conical tube are formed with inner flanges, and these serve
as guides to the wick and as supports to the parallel tube which is fastened to
them. The lower parts of the tape to form the wick are kept at a distance apart,
and gradually approach each other while being raised so as to meet at the top of
the burner, and form a circular wick, each half or portion of the tape or cotton
being raised simultaneously and at the same speed by wheels which receive their
motion, one through the intermediation of an idle wheel, and the other through a
wheel on the spindle of the thumb or turn button, from which latter wheel the idle
wheel receives its motion,

RICHARD SCHREIBER, of Red Cross Street, in the City of London, Lamp Manu-
facturer. "IMPROVEMENTS IN AND CONNECTED WITH BURNERS FOR PARAFFIN AND
SIMILAR MINERAL OIL LAMPS."
This Invention relates to improvements in and connected with burners for paraffin
and similar mineral oil lamps, and consists in forming a double slit or a circular slit
with partitions or division plates in and from the bottom plate of the burner that
the ends of separate flat tapes or webs of the usual cotton can be pushed into
them and be raised as desired by wheel or other appliances fitted within the barrel
portion.
Above the bottom plate and depending from the top of the inner of the burner
tubes is a parallel tube, with parts of the lower end removed to admit of air passing
into the interior of the flame, the projections between the cut away parts serving as
deflectors and diffusers of the air, and also to keep the burner cool.
The tubes which carry the wicks are of conical form from the bottom upwards,
and have apertures formed with flanges or partitions as guides to the wicks
The lower parts of the tapes to form the wick are kept at a distance apart, and
gradually approach each other while being raised so as to meet at the top of the
burner, and form a circular wick, each half or portion of the tape or cotton being
raised simultaneously and at the same speed by wheels which receive their motion,
one through the intermediation of an idle wheel, and the other through a wheel on
the spindle of the thumb or turn button, from which latter wheel the idle wheel
receives its motion.
The arrangement of wheels just described is applicable to other lamps in which
two flat wicks are used, or one circular wick wick, to ensure a level raising of the
same.
My Invention will be clearly understood by the annexed Drawings, in which
Figure 1 is a view of the bottom or base plate a of a burner of a paraffin or hydro-
carbon oil lamp, in which two flat wicks can be caused to approach each other and
meet in a circular or ring form to be burned as a circular wick, as is more
particularly shown in the transverse section of the burner in Figure 2.
My burner is composed of two tapered tubes b, c, one enclosed within the other,
and at a distance apart corresponding to the thickness of the wicks to be used.
These tubes have A shaped openings & formed in their sides at the lower or larger
ends, as in Figure 3, and the edges of these are closed up by flanges or shaped strips
of metal e, e, braized in or otherwise fitted to retain the parallelism of the two tubes,
and to form distinct segmental passages f, f, for the wicks g, g, to move up in when
they are lifted by the pinions h, h, as in the ordinary way of flat wicks in single
cotton lamps. The passages f, f, in which the wicks g, g, are, forn segmental tubes
at the lower part of the tapered tubes b, c, and near the upper part the segmental
tubes merge into one, and form a single tube of circular shape at the top, from
which the two flat wicks appear as one circular wick for burning, as shown in
Figure 2.
The area of the two segmental tubes at the lower part is equal to the area of the
ring shaped opening at the top; consequently the wicks simply approach each
other as they are lifted.
The A shaped openings d, d, in the tubes b, c, serve for the admission of air from
the exterior casing i to the interior of the flame, as is indicated by the arrows in

page_text: Figure 4. Within the inner of the burner tubes b, c, is a parallel or straight sided
tubej depending from the upper edge thereof, and this has A shaped channels k, k,
on two of its sides at the lower part, but arranged at right angles to the A shaped
openings d, d, in the tapered tubes, so that the wings L, L, between the A's of the inside
tube b take a position opposite, and serve as deflectors or diffusers of the air entering
to the centre of the flame, as will be understood by the arrows in Figures 4, 5,
and 6.
The two wicks g, g, in my lamp burner are raised simultaneously by pinions h, h,
one of which is actuated by the driver m, which is upon the spindle n, carrying the
usual outside thumb button p, and the other is through the intermediate or idle
pinion q, as in Figures 1 and 4.
The tubes b, c, j, before referred to are enclosed in a perforated casing i, which
admits air to the exterior of the flame as well as to the interior of it, as shown in
Figure 4, the outside supply being augmented by other apertures or perforations in
the chimney carrier », the bottom portion of which has raised projections at intervals
for the chimney to rest upon in order to keep it clear of the holes.
The "burner" is carried by a flanged ring 8, as in Figure 7, by which the attach-
ment is made to the oil reservoir or body part of the lamp pedestal u, which flanged
ring is covered by another flanged ring or bezel t
Each of these rings has an elongated hole vin it, as in Figure 7, and the shift or
turn round of the loose one to the distance limited by a stop pin w will cause the
hole in the fixed ring to be covered, a reverse action causing the two holes to come
one over the other to facilitate the pouring of oil into the reservoir u without
unscrewing and removing the burner from the body, as is now done. This plan,
which facilitates charging the vessel with oil, is applicable to all oil lamps burning
hydrocarbon oils.
Figure 8 is a top view of the tube portions of the burner, and Figure 9, a sectional
view through the line x, x, of Figure 6
I am aware that two flat wicks have been employed in hydrocarbon oil lamps to
form a circular wick for burning with a ring shaped flame, but this in itself forms
no part of my Invention
And having now described the nature of my said Invention, and the manner in
which the same is to be performed, I, declare that I claim,-
Firstly. The construction and general combination of burner, as described and
shown in the annexed Drawings.
Secondly. The employment of tapered tubes of circular form for two flat wicks which
are apart at the bottom of the burner, and together at the upper part as a circular
wick in lamps burning hydrocarbon oils, such tapered tubes having air slits for
ventilation, and with side walls for guiding the cottons into circular form, as described
and substantially as shown in the annexed Drawings.
Thirdly. I claim the employment of four pinions actuated by an outside thumb
button, two of which act upon separate wicks to raise said wicks simultaneously in
hydrocarbon oil lamps, as described, whether in the lamp shown in the Drawings
or in others, as set forth
Fourthly I claim the fitting of a sliding ring on the ring or bezel connecting
the burner to the body of a hydrocarbon lamp, said rings having a hole in each to
facilitate filling the body with oil, and to shut off communication by a sliding action,
as described and substantially as shown in the annexed Drawings.
In witness whereof, I, the said Richard Schreiber, have hereunto set my hand
and seal, this First day of March, in the year of our Lord One thousand
eight hundred and seventy-seven.
