page_text: 1, JOHN FREDRICK SCHNELL of 14 Gray Street Temperance Street Manchester,
in the County of Lancaster Mechanic do hereby declare the nature of this invention
to be as follows :-
To provide a safe, and useful lamp, and burner, for illuminating purposes for the
use of Moulders, Mechanics, &c., to burn a mixture, of volatile, hydro-carbons and
rendering the same safe, to be used with this lamp, and burner, I effect my object by
useing, a metal tube, attached to a thread, or screw, to which is attached another tube,
of larger dementions, 1 hereby cause to be inserted, in these tubes, asbestos, fibre, or
cotton wool, or its equivelent, on the top of the smaller tube, I afix a cap, which I
perforate with any required number of holes, the larger tube, is allowed to be inserted
in the oil vessell, or lamp, which tube is sealed at the bottom, with a small slit up the
side, by which the oil enters, thence the oil is taken to the smaller tube, by the aid of
capillary attraction, on a light being applied to the burner, a gas is generated, which
burns through the perforations as above.

I, JOHN FREDRICK SCHNELL of 14 Gray Street Temperance Street Manchester
Mechanic 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 provide a safe and useful Lamp and burner for
illuminating purposes for the use of Moulders, Mechanic's &c. &c. To burn a mixture
of volatile, hydro carbons and rendering the same safe to be used with this Lamp &
Burner, I effect my object by useing a metal tube attached to a thread or screw to
which is attached another tube of larger dimensions I hereby cause to be inserted in
these tubes asbestos fibre, cotton wool or its equivalent. On the top of the smaller tube
I affix a cap which I perforate with any required number of holes the larger tube is
allowed to be inserted in the oil vessel or lamp which larger tube is sealed at the
bottom with a small slit up the side by which the oil enters, thence the oil is taken,
to the smaller tube by capillary attraction when a light is applied to the top of
burner, a vapour or gas is generated which burns through the perforations in the
burner. The burner may be perforated with any number of holes which may be
placed in any form, thus the shape of the light may be modified according to fancy.
The hydrocarbon oil used for this lamp is benzoline spirit or its equivalent, with which
I mix common salt in the proportion of one ounce to a gallon of the spirit or their
about, which renders it less liable to explode. I do not confine myself to this
particular form of lamp as it may be modified in form without departing from the
invention. The following is a description of the drawing. A is the body or oil
vessel. B is the smaller metal tube. C the screwed cover which secures the small
tube and burner to the body of the lamp. E is the perforated cap or burner which is
attached to the tube B. D is a tube of larger diameter which protrudes down wards
into the body of the lamp.
Having now described the nature of my invention and in what manner the samo
may be performed I now claim.
1st. The method of treating the benzoline spirit for use in this lamp with a mixture
of common salt.
2nd. The combination of the perforated burner and tube.
3rd. The general arrangement of lamp and burner as described and shown.
