for the Invention of "IMPROVEMENTS IN PETROLEUM LAMP BURNERS, AND IN
THE MODE OF ADMITTING THE PETROLEUM THERETO."
Sealed the 10th May 1878, and dated the 12th November 1877.
PROVISIONAL SPECIFICATION left by the said Rudolph Ernst Asmis at the
Office of the Commissioners of Patents on the 12th November 1877.

THERETO.

This Invention relates to improvements in the construction of petroleum lamp
burners, and in regulating the admission of the petroleum thereto.
It consists of a burner perfectly isolated from the petroleum holder. The petroleum
is conducted from the holder to the burner by an admission or inlet tube, and is
regulated by a valve so that the quantity of petroleum admitted is just sufficient
for the consumption.
To avoid the dropping of the petroleum the valve may be furnished with a joint,
which extends to the highest mark of the petroleum, or the valve may be put
within the holder.
The wick is incombustible and fixed; it can neither be raised nor lowered.
It consists of some porous mineral in the form of a wedge, which sticks closely to
the burner.
.
Beneath the wick is a little canal, by means of which the petroleum may freely
circulate round the wick and may be sucked by it uniformly. The highest mark
of the petroleum in its holder is fixed at half the height of the wick.
The principal use which may be made of this new burner is for cooking apparatus,

page_text: for lamps, and stores, of course all fed with petroleum, and the advantages of the
Invention are,-
1. A better flame.
2. The complete removal of all cause for explosion.
3. The great facility with which it may be used, as there is no cutting or
cleaning of the wick.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Rudolph Ernst Asmis in the Great Seal Patent Office on the 10th May

This Invention relates to improvements in the construction of petroleum lamp
burners, and in regulating the admission of the petroleum thereto.
It is illustrated by the accompanying Drawing, where Fig. 1 is a vertical section,
and Fig. 2, a plan thereof.
This Invention consists of a burner a perfectly isolated from the petroleum holder.
The petroleum is conducted from the holder to the burner a by an admission or
inlet tube b, and is regulated by a valve c so that the quantity of petroleum
admitted is just sufficient for the consumption.
To avoid the dropping of the petroleum the valve c may be furnished with a joint
which extends to the highest mark of the petroleum, or the valve c may be put
within the holder.
The wick g is incombustible and fixed; it can neither be raised nor lowered.
It consists of some porous mineral in the form of a wedge, which sticks closely to
the burner.
Beneath the wick is a little canal ƒ, by means of which the petroleum may freely
circulate round the wick g and be sucked by it uniformly. The highest mark of
the petroleum in its holder is fixed at half the height of the wick g.
The principal use which may be made of this new burner is for cooking apparatus,
for lamps and stoves, of course all fed with petroleum, and the advantages of the
Invention are,—
1. A better flame.
2. The complete removal of all cause for explosion.
3. The great facility with which it may be used, as there is no cutting or cleaning
of the wick.
Having now described and particularly ascertained the nature of my said
Invention, and the manner in which the same is or may be used or carried into
effect, I would observe in conclusion that what I consider novel and original, and

page_text: therefore claim as the Invention secured to me by the herein-before in part recited
Letters Patent is, the combination of the isolated petroleum burner a with incom-
bustible wick g and regulating valve c, substantially as and for the purpose herein-
before described and illustrated.
In witness whereof, I, the said Rudolph Ernst Asmis, have hereunto set my
hand and seal, this First day of May, in the year of our Lord 1878.
