Improvements in the Manufacture of Lamps Applicable for
Velocipedes and other Purposes.
We WILLIAM Bown, of 308, Summer Lane, Birmingham, in the county of
Warwick, Manufacturer, and ROBERT BENJAMIN CHALMERS, New John Street West,
Birmingham, aforesaid, Lamp Maker, do hereby declare the nature of this invention
to be as follows:-
Our improvements apply to those lamps which require lighting in exposed positions
and in which colza or other such like oil is used for illuminating them, and have for
their object the facilitating of igniting the oil wick.
In carrying out our improvements we construct the oil reservoir either in two
parts or in such a manner that an independent chamber is provided. The main or
larger part of the reservoir is for holding the burning oil and the independent or
smaller chamber is for holding methylated spirit, paraffin or other volatile oil. The
burner is provided with two or more separate wick tubes and winders or their
equivalents, the object being to connect the two wicks at the time of lighting. The
end of the wick for burning dips into the oil in the larger reservoir or chamber and
the end of the wick for facilitating the lighting dips into the spirit or oil in the
independent or smaller chamber.
When it is required to light the lamp in exposed positions as in the case of cyclists'
and other lamps, the door of the lamp being opened, the wick belonging to the
smaller chamber containing the spirit or volatile oil is raised by the winder and can be
readily lighted by the application of an ordinary match, then the wick belonging to
the main reservoir or chamber containing the burning oil is raised until it comes in
contact with the flame from the spirit or volatile oil wick, which readily ignites it ;
this being done, the wick containing the spirit or volatile oil can be wound down into
the tube, thereby extinguishing that flame, and leaving the flame proper thoroughly
lit up. Thus, by the introduction of the additional chamber, wick tube and winder,
or their equivalents, with the spirit or volatile oil, we are enabled to greatly facilitate
the lighting of lamps required to be lit in the open air or exposed situations.

Improvements in the Manufacture of Lamps Applicable for
Velocipedes and other Purposes.
We WILLIAM BOWN of 308 Summer Lane Birmingham in the County of Warwick
Manufacturer and ROBERT BENJAMIN CHALMERS of New John Street West
Birmingham aforesaid Lamp Maker do hereby declare the nature of our said
invention for "IMPROVEMENTS IN THE MANUFACTURE OF LAMPS APPLICABLE FOR
VELOCIPEDES AND OTHER PURPOSES and in what manner the same is to be 5
performed to be particularly described and ascertained in and by the following
statement:
"
Our improvements apply to those Lamps which require lighting in exposed positions
and in which colza or other such like oil is used for illuminating them and have for
their object the facilitating of igniting the oil wick.
In carrying out our improvements we construct the oil reservoir either in two
parts or in such a manner that an independent chamber is provided-The main or
larger part of the reservoir is for holding the burning oil and the independent or
smaller chamber is for holding methylated spirit paraffin or other volatile oil-The
burner is provided with two or more separate wicks tubes and winders or their
equivalents the object being to connect the two wicks at the time of lighting.
The end of the wick for burning dips into the oil in the larger reservoir or
chamber and the end of the wick for facilitating the lighting dips into the spirit or
oil in the independent or smaller chamber-When it is required to light the lamp in
exposed position as in the case of cyclists and other lamps-the door of the lamp
being opened the wick belonging to the smaller chamber containing the spirit or
volatile oil is raised by the winder and can be readily lighted by the application of an
ordinary match then the wick belonging to the main reservoir or chamber containing
the burning oil is raised until it comes in contact with the flame from the spirit or
volatile oil wick which readily ignites it-this being done the wick containing the
spirit or volatile oil can be wound down into the tube thereby extinguishing that
flame, and leaving the flame proper thoroughly lit up, thus by thefintroduction of the
additional chamber wick, tube and winder or their equivalents with the spirit or
volatile oil, we are enabled to greatly facilitate the lighting of lamps required to be
lit in the open air or exposed situations.
But as our improvements will be best understood by reference to the drawings
hereunto annexed we will proceed to describe the same in connection therewith.

page_text: spirit or volatile oil-Figure 4. is a transverse section of the reservoirs and burner
complete-Figure 5. is a top view of Figure 3 and Figure 6. a top view of figure 1.
A. A are the winders the heads or knobs of which project outside the lamp body, for
winding the wicks B. B¹ up or down-The wick tubes C. D. are placed by preference
in inclined positions as shown so that the wicks may be brought in close contact for
ignition E. is the large reservoir for holding the colza or other burning oil and F. is
the smaller chamber for holding the methylated spirit paraffin or volatile oil, and by
reference to Figures 1. and 4. it will be seen that by turning the winder knob A the
wick in the tube C, may be raised for lighting by the toothed wheel a, and this also
may be said of the winder knob A' and wick in the tube D. The cap or cover J. has
two slots formed in it marked G. H. see figure 5. through which the wicks pass to
their respective reservoirs-the wick tubes C. D. are secured in the bottom of the
winder body I. figure 2. by soldering or otherwise and in order that there shall not
be any escape of spirit or volatile oil from the chamber F. or oil from the oil
reservoir E. we place a leather or other suitable washer K. between the bottom of
the burner and the cap or cover as seen at Figure 4, which is held in position by
screwing down the ring L. figure 2 tightly upon it.
When it is desired to light the lamp the side trap or door having been opened the
winder A. is turned in the right direction which raises the wick B. in connection
with the spirit reservoir, which wick can be instantly lighted by an ordinary match,
then the winder A. is turned and the wick in connection with the oil reservoir E. is
raised until it is in contact with the lighted wick which readily ignites it. This being
done the wick in connection with the spirit chamber F. can be wound down thereby
extinguishing it but leaving the flame proper thoroughly well lit.
The spirit and oil can be readily poured into the respective chambers by unscrewing
and removing the knobs L. and M.
From this description it will be seen that by the use of this extra wick in
connection with paraffin spirit or other volatile oil increased facility is afforded for
lighting cycle and other lamps, particularly when being lit in the open air during
violent or high winds and in exposed positions.
Having described our invention and the manner of giving effect to the same we
wish it understood that we do not purpose confining ourselves to the exact details
herein described and exhibited, but what we claim and wish protected by letters
patent is,
The construction of burners and reservoirs of bicycle and other lamps substantially
as herein described and exhibited, that is to say, providing an extra winder, tube,
wick and receptacle or chamber for holding spirit or volatile oil for facilitating the
lighting of such lamps.
