IMPROVEMENTS IN LAMP GLOBES AND SHADES
Year: 1884

page_text: We FREDERICK JOHN BIERTUMPFEL and HENRY AUGUSTUS BIERTUMPFEL, both
of Albany Street, Regent's Park in the County of Middlesex, Candle Mould Makers
do hereby declare the nature of said invention for "IMPROVEMENTS IN LAMP
GLOBES AND SHADES" to be as follows:-
"
According to this invention we construct globes and shades for gas and other
lamps or lights with a frame which is made to drop onto or be fixed to the burner,
pipo or other part of the lamp or light but by preference onto the ordinary globe
holder. The frame is constructed with ribs, bars or parts made to receive "fields"
panes or slides of glass or other transparent or partly transparent material, so as
to be readily removed and changed at will. These "fields" are intended to contain
designs, ornaments, writing, advertisements, texts, photographs, or other art
productions thus enhancing the beauty and value of the globe or shade. The form
of the latter may be conical, straight, or curved. Sometimes one part of it may
be fitted with a field or fields of looking glass towards the interior and another
part with the aforesaid transparent or partly transparent fields so that the looking
glass part acts as a reflector. Sometimes we make one or more of the panes to
form looking glasses towards the exterior.
When we employ fields of ornamental coloured glass having parts through which
the flame would be clearly visible we prefer to treat the back or inside of such
parts of the glass by means of sand blasting or other known methods in such
manner as to render them opaque thus not allowing the flame to be seen through
the said parts from the outside.
The panes when thus made removablo may readily and in a moment be replaced
by new ones when injured or when a change is desired.
We prefer to employ the aforesaid shades and globes in connection with globe
holders of such a size as to permit a great part of the light to be diffused
downwards,

of Albany Street, Regents Park in the County of Middlesex Candle Mould Makers
do hereby declare the nature of said invention for "IMPROVEMENTS IN LAMP
GLOBES AND SHADES and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement:-
"
According to this invention we construct globes and shades for gas and other
lamps or lights with a frame which is made to drop on to or be fixed to the burner,
pipe or other part of the lamp or light but which by preference when used as
a substitute for an ordinary "globe" is made to drop on to or be fixed to the
ordinary globe holder and when used as a substitute for an ordinary shade is made
to drop on to the globe or into part of the globe holder like an ordinary shade.
In the accompanying drawings we have illustrated a few out of the many modes
in which this invention may be carried into effect but individual fancy or taste
and other requirements will in many cases decide as to the most suitable form.
Figure 1 is a perspective view of a globe constructed according to our invention.
It consists essentially of two parts, viz:-the frame itself and the fields, panels,
panes or slides which are inserted in the frame. Figure 2 is a perspective view
showing the frame itself. The frame A is constructed with ribs, bars or parts A'
which are made to receive the fields, panes panels or slides B of glass or other
transparent or partly transparent material, in this case six in number and one,
more or all of these panes B may be at any time removed and changed and thus
varied as desired or required as regards the words, colours, designs, form and
general make. Each pane B is inserted in the frame and held by the small clips A²
at the sides, and the clips A³ at the bottom and may thus be readily removed and
changed when injured or when a change is desired. But we do not confine
ourselves to any particular form of clips and instead of clips we may use grooves,
screws or any other suitable means for holding. The globe is in this case shown
as resting on the ordinary globe holder, which we believe generally will be found
the most suitable but it might be made to screw on to the gas pipe (or other part
of lamp.) Figure 3 shows a straight form of "globe" in which the frame A as an
example is shown screwed directly on to the gas pipe (or other part of a lamp)
But it might be made to fit on to a globe holder as shown in the previous example.
Figure 4 shows an ordinary globe provided with a shade which in this case is
simply dropped on to the globe. As are split pins for holding the panes B in place.
We may also if desired make the frame in parts each part forming a rim to
a pane and provided with means for uniting these parts or rimmed panes. Figure 5
shows a pane B by itself and Figure 6 shows a pane B provided with a thin
metallic rim A baving side flanges A¹ for connecting them.
Figure 7 is a part plan view showing one mode in which the rimmed panes may
suitably be connected, viz by means of split pins A¹².
The fields, panes, panels or slides B are intended to contain designs ornaments,
writing advertisements, texts, photograps or other art productions thus enhancing
if desired the beauty and value of the globe and shade. The form may be conical
or straight as shown in the drawings, or curved. Sometimes one part of it may be
fitted with a field or fields of looking glass towards the interior and another part
with the aforesaid transparent or partly transparent fields, so that the looking glass
part acts as a reflector. Sometimes we make one or more of the panes to form
looking glasses towards the exterior. As applied to shop windows we may arrange
half the panes for one kind of advertisement and half for another, and by

page_text: occasionally turning the globe or shade half round we change the advertisement
without even changing the panes or fields in their places in the frame.
When we employ fields of ornamental coloured glass having parts through which
the flame would be clearly seen we prefer to treat the back or inside of such glass
by means of sand blasting or other known method so as to render them somewhat
opaque thus not allowing the flame to be seen through the said parts from the
outside. Sandblast may also suitably be employed for removing the coloured parts
of the glass where desired.
We prefer to employ the aforesaid shades and globes in connection with globe
holders of such a size as to permit a great part of the light to be diffused
downwards.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we Claim is :-
First: Constructing "globes" and shades with detachable or removable panes,
panels or fields substantially as and for the purposes set forth.
Second: The employment of globes and shades constructed as set forth, for
advertising purposes.
