Year: 1885

I, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35 Southampton Buildings, Chancery Lane, in the County of
Middlesex do hereby declare the nature of the invention for IMPROVEMENTS
IN OIL LAMPS" (a communication to me from abroad by Wilhelm Bertram, of
Lauban, Silesia) to be as follows:-
This invention relates to ordinary lamps burning mineral or other oils, and it has.
for its object a novel method of construction of such lamps by which the holder
which carries the chimney and globe or shade of the lamp can be readily raised or
lowered so as to give free access to the wick for the purpose of lighting and
extinguishing it, the chimney and globe remaining upon the lamp.
To the ordinary holder which fits round the wick tube of the lamp and carries
the chimney and globe or shade, three or more arms are attached descending
downward and having their lower ends turned in horizontally and fitting and
sliding in corresponding vertical grooves or guides formed upon or fixed to the
conical sides of the wick tube.
The holder, therefore, together with the chimney and globe can be raised when
desired, and the upper ends of the vertical grooves or guides may be provided with
lateral recesses into which the projecting ends of the arms can be turned when the
holder has been raised to its highest point, so as to keep it there whilst the lamp is
lighted or extinguished or the wick trimmed, free access being obtained for the
purpose between the arms without the chimney or globe being entirely removed
from the lamp.

I, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of
Middlesex do hereby declare the nature of this invention (a communication to mo
from abroad by Wilhelm Bertram of Lauban, Silesia, in the Empire of Germany,
Engineer) and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement and accompanying
drawing (that is to say) :-
This invention relates to ordinary lamps burning mineral or other oils, and it has
for its object a novel method of construction of such lamp by which the holder
which carries the chimney and globe or shade of the lamp can be readily raised or
lowered so as to give free access to the wick for the purpose of lighting and
extinguishing or trimming it, the chimney and globe remaining upon the lamp.
The accompanying drawing is in illustration of the invention, and shews a
perspective view of the device.
To the ordinary holder a which fits round the wick tube of the lamp and carries
the chimney and globe or shade, three or more arms c are attached descending
downward and having their lower ends turned in horizontally at c¹ and fitting and
sliding in corresponding vertical grooves or guides e formed upon or fixed to the
conical sides of the wicktube d. The holder a therefore together with the chimney
and globe can be raised when desired, and the upper ends of the vertical grooves or
guides e are provided with lateral recesses e¹, into which the projecting ends c¹ of
the arms c can be turned when the holder a has been raised to its highest point, so
as to keep it there whilst the lamp is lighted or extinguished or the wick trimmed,
free access being obtained for the purpose between the arms c without the chimney
or globe being entirely removed from the lamp.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
The combination with the chimney and globe holder a, of the downwardly
descending arms c having inwardly projecting ends c¹, and the grooves e having
lateral recesses e¹, substantially as and for the purposes described and shown.
