"IM-
PROVEMENTS IN BURNERS FOR PETROLEUM LAMPS." A communication from abroad
by Ernst Heinrich Haeckel, of Breslau, Empire of Germany.
The improvements relate to round or flat burners for petroleum-lamps, the object
being to obtain a sure and equal gear of the wick within the wick-holder; the wick
may be thick or thin, smooth or rough, or knotted (because of false weft), and
consists in the use of springs and their proper appliance to press the wick against
the toothed driving wheels, or in the contrary to press the toothed driving wheels
against the wick.
In round burners the wick is pressed by spring to the driving wheel, or the
latter is by spring pressed to the wick.
In a flat-burner the wick is pressed by the springs to the driving wheels, or two
springs are employed, one of which presses the wick to the driving wheels, and the
second presses in the meantime the wick against the first one, by which means a
sure and hermetical conclusion of the flame from the oil-cassin is obtained.
In the first named construction the round burner is of common form, but the
outside conical socket of the wick-holder is fitted on both sides with two
rectangular boxes, the sides of which latter are parallel to the front sides of the
driving wheels. Within these so called spring-boxes are established flat shaped
springs, the convex side of which corresponds with the periphery of the driving
wheels.
These springs are attached to the lower end of the spring boxes connected with
the outer socket of the wick holder.
The wick entering the lower end of the wick holder arrives between the springs
and the driving wheels, and in consequence is propelled by the driving wheels
equally.
It is clear that the springs not only conduct proportionally and in an equal
manner the wick of a determinated thickness, but that also a wick of greater or
smaller thickness is held by the force of the springs and equally propelled. Even
the knots so often found in the wicks pass the space between the wheels and the
springs by the elasticity of the last ones, and do not cause stoppage nor inequality
of parts of the wick.

page_text: The like result is obtained by the use of an inner socket; the wick holder is
fitted with the bridge at the top of the airtriangle, and to this bridge are attached
four springs. The lower ends of the springs are fitted in pairs with the sockets of
the wheel-shafts, which-is-opposite-to-the first, not connected together but
independent of each other.
Springs are employed to press the driving wheels to the outer socket of the wick-
holder; and the same purpose is obtained-as-with the construction first described.
For a flat burner with one spring only; the wick-holder-of-the-flat-burner differs.
_from_the_construction heretofore used, as its horizontal projection-is-a-sharp-edged.
rectangle, so that the spring which presses the wick to the driving-wheels-is-
_fastened to the lower end of the wick holder, and is of the same breadth as the side
longer dimension of the rectangle.
The wick holder is about the convexity of the spring, a little wider than the
wick would be without the spring. The wick itself is secured against stopping at
the end of the spring by the protection sheet at the side of the wick-holder's mouth.
It is evident that this construction has the same advantages with the flat burner
as with the first and second construction with round burners.
A fourth construction also apply able to flat burners consists of a wick holder
fitted with two springs which are soldered, to the lower end of it, and the upper
ends of the springs are secured behind the protection sheets for the purpose
aforesaid.
One of the springs presses the wick to the driving wheels, whilst the otlier spring
at the side of. the driving wheels is slit for depressing the wheels, and presses the
wick with its convexity against the convexity of the spring, by which means a
hermetical connection between the flame and the cassin is obtained.
The afore mentioned improvements in petroleum flat and round burners are, in
consequence of the equal gearing and moving the wick, of high preference, because
wicks can be used for which a slightly twisted yarn and a soft and rich cotton
web is sufficient, that is to say, it is possible to use wicks of the highest quality,
of suction, so that the principal condition of a fine, clear, and straight flame is
secured.
