PROVISIONAL SPECIFICATION.
Improvements in Screens or Shades for Lamps and Gas or Electric
Lights.
I, SAMUEL CLARKE, of the Pyramid Works, Cricklewood, in the County of
Middlesex, Night Light Manufacturer, do hereby declare the nature of this inven
tion to be as follows:-
This invention has mainly for its object to provide ornamental shades for small
candle lamps known as "Fairy" lamps and for other such like lamps but is also
applicable for shades for gas electric and other burners. I form a screen or shade
of a number of solid pillars of glass or tubes of glass filled with transparent liquid
of various colors and held together side by side in a metal framework so as to form
a hollow cylinder which may be of polygonal or other form in cross section and form
a lantern to surround the flame of the lamp.
The tubes may be ranged vertically and in that case need not be hermetically
closed at the top but be left open so that if desired the liquid within them may from
time to time be changed for liquid of any other desired color.
The bottom of the frame in which the tubes are held may be formed from a ring
of metal which is trough shape in vertical cross section the width of the trough
being just sufficient to allow of the lower ends of the tubes passing into and being
held by it. The top may be of a similar trough ring but inverted to hold the tops
of the tubes and the troughs may be held together by three or other number of
metal rods passing vertically from one to the other-these rods may be surrounded
with glass tubes of the same diameter as the tubes which contain liquid. If the
lantern is polygonal the tubes are made of such a diameter that there may be a tube
at each corner of the polygon and the space between them occupied by other
tubes meeting together side by side.

Improvements in Screens or Shades for Lamps and Gas or Electric
Lights.
I, SAMUEL CLARKE, of the Pyramid Works, Cricklewood, in the County of
Middlesex, Night Light Manufacturer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement :-
This invention has partly for its object to provide ornamental shades for small
candle lamps known as "Fairy" lamps and for other such like lamps but is also
applicable for shades for gas electric and other burners. I form a screen or shade
of a number of solid pillars of glass or tubes of glass filled with transparent liquid
of various colors and held together side by side in a metal framework so as to form
a hollow cylinder which may be of polygonal or other form in cross section and
form a lantern to surround the flame of the lamp.
The tubes may be ranged vertically and in that case need not be hermetically
closed at the top but be left open so that if desired the liquid within them may from
time to time be changed for liquid of any other desired color.
The bottom of the frame in which the tubes are held may be formed from a ring
of metal which is trough shape in vertical cross section the width of the trough
being just sufficient to allow of the lower ends of the tubes passing into and being
held by it. The top may be of a similar trough ring but inverted to hold the tops

page_text: of the tubes and the troughs may be held together by three or other number of
metal rods passing vertically from one to the other-these rods may be surrounded
with glass tubes of the same diameter as the tubes which contain liquid. If the
lantern is polygonal the tubes are made of such a diameter that there may be a tube
at each corner of the polygon and the space between them occupied by other tubes
meeting together side by side.
In the drawing annexed I have shewn a screen or shade constructed as above
described for a small candle lamp known as a Fairy lamp but as above stated orna-
mental shades or screens similarly constructed may be used with gas electric or
other burners.
Figure 1 is an elevation of the lamp and screen.
Figure 2 is a similar view partly in section.
Figure 3 is a cross section on the line ab Figure 2 and
Figure 4 is a cross section on the line c d.
A B are two metal trough rings each hexagonal in plan view these are held
together at a distance apart from one another by threefinetal rods C at three of
the corners of the hexagons. Through the upper one A there are also formed
three holes D at the three other corners of the hexagon. EE are glass tubes
filled with colored liquid these may advantageously be closed at the top by small
corks varnished or cemented over.
The tubes may be inserted into their places by taking them one by one and
inserting the upper end through one or other of the holes D and then lowering
the tube and allowing its lower end to rest in the bottom trough B and then
shifting the tube sidewise into the position it is to occupy.
Ex is the glass lamp containing the small candle. The lower part of the lamp
is dropped through a sheet metal ring F-two wires rise up from this ring and
at their top are secured to a metal plate G which is of a shape to fit within
the centre of the upper hexagonal ring A. H is an outlet chimney rising up
from the centre of the plate G. I is a wire handle jointed to this plate.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. The construction of screens or shades for lamps and gas or electric lights
of glass rods or tubes filled with transparent liquid placed together side by side
and held within a metal framework substantially as described.
2. The construction of screens or shades for lamps and gas or electric lights
substantially as hereinbefore described and illustrated in the drawing annexed.
