IMPROVEMENTS IN HYDRO CARBON STOVES AND LAMPS FOR LIGHTING AND HEATING
Year: 1879

page_text: LETTERS PATENT to William Burd Woolley, of Bridge St. West, Birmingham,
in the County of Warwick, Toolmaker, for the Invention of "IMPROVEMENTS
IN HYDRO CARBON STOVES AND LAMPS FOR LIGHTING AND HEATING."
Sealed the 23rd March 1880, and dated the 29th September 1879.
PROVISIONAL SPECIFICATION left by the said William Burd Woolley at the
Office of the Commissioners of Patents on the 29th September 1879.
WILLIAM BURD WOOLLEY, of Bridge St. West, Birmingham, in the County of
Warwick, Toolmaker. "IMPROVEMENTS IN HYDRO CARBON STOVES AND LAMPS FOR
LIGHTING AND HEATING."
This Invention consists in an improved arrangement for extinguishing the flames
of benzoline or other hydro carbon lamps, and is accomplished as follows:-I sur-
round or partially surround the wick case with a metal case or tube so arranged
that it may be made to slide up or down upon the wick case by a lever or any
suitable arrangement, the top of which sliding tube or casing I prefer to slope off to
an angle of about forty five degrees or more. On the lower side of this sliding wick
case I attach a thin spring of steel or other elastic metal so shaped and arranged as
that when the sliding case is raised up above the wick case it springs over and so
covers the tap of the sliding case as to enclose the wick and completely extinguish
the flame of lamp. When the sliding case is forced down it readily opens and is
drawn down with the sliding tube below the top of the wick case, and thus when
in this position in no way interferes with the burning of the lamp.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Burd Woolley in the Great Seal Patent Office on the 27th
March 1880.

page_text: that it may be made to slide up or down upon the wick case by a lever or any
suitable arrangement, the top of which sliding tube or case I prefer to slope off to
an angle of about forty five degrees or more. On the lower side of this sliding tube
or case I attach a thin spring of steel or other clastic metal so shaped and arranged
as that when the sliding tube or case is raised up above the wick case the elastic
piece of metal springs by its own elasticity and so covers the top of the sliding case
as to enclose the wick and completely extinguish the flame of lamp. When the
sliding case is forced down the spring readily opens and is drawn down with the
sliding tube below the top of the wick case, and thus when in this position in no
way interferes with the burning of the lamp. And in order that this my said
Invention may be readily understood and carried into effect I will now proceed to
describe the same by reference to the annexed Drawings.
Figure 1 is a perspective view of the top (or wick tube part) of a benzoline or
other hydrocarbon lamp with my apparatus for extinguishing the flame applied
thereto, and shews the same in the position (with respect to the wick tube) it would
occupy when not in use, or as it would be when the lamp is alight.
Figure 2 is a similar perspective view to that shewn in Figure 1, but in this caso
my apparatus is shewn in use, that is, raised to such a level as to close over and
extinguish the flame of lamp.
Figure 3 is a vertical section of lamp top with my apparatus applied thereto, and
in the position shewn in Figure 2. a is the wick tube, on this I place a sliding case
or tube b, the upper end b¹ of which I level to an angle of about 45 degrees or more,
and on the lower side of this outer tube or case b I attach a thin spring c of steel
or other elastic metal suitably shaped to agree with the bevel mouth b' of the tube b,
and arranged as shewn. This spring c is "set" so as to close up the bevel mouth
of the tube when free to do so, namely, when my apparatus is raised so that the
inclined or bevel top b¹ comes above the wick tube a, for the latter being withdrawn
from between the bevel mouth b¹ and the spring c the spring by the tendency given
it when "set" closes the bevel end or mouth b' of the tube or case b and extin;
guishes the wick contained therein. The apparatus is moved up or down at
pleasure by simply pressing (in the required direction) on the finger piece or lever d.
There is a dented groove e in the side of wick tube a in which a projection f inside
the case or tube b slides, which regulates the amount of use of the case b, and also
keeps it in position laterally.
It is obvious that this Invention is equally applicable to lamps used in hydro
carbon stoves.
Having thus particularly described my said Invention, I declare that what I
claim and desire to be secured to me by the hereinbefore in part recited Letters
Patent is,―
The combination and arrangement of parts, whereby the elastic piece of steel or
other metal attached to a sliding case or tube of a lamp, and arranged as described,
so that when it is raised up it will by its own elasticity close the top of the sliding
tube or case above the wick, and thus effectually extinguish the flame, substantially
as herein before described and as shewn on the Drawings.
In witness whereof, I, the said William Burd Woolley, have hereunto set my
hand and seal, this Twenty sixth day of March, in the year of our Lord One
thousand eight hundred and eighty.
