PROVISIONAL SPECIFICATION.
Improved Manufacture of Globes and Chimneys for Gas and Oil
Lamps.
I, JAMES STOTT, of Vernon Works, Lee Street, Oldham, County of Lancaster,
Gas Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has for object, improved manufacture of Globes and Chimneys
for Gas and Oil Lamps.
For the purpose of my invention, I employ soft hot glass in thread, cord, or
wire like form, and wind it on a mandrel or pattern and cause it to conform to
the shape of same.
The glass need not be of the same colour since various colours of glass can be
used for the purpose according to the desired artistic appearance of the Globe
or Chimney that has to be produced.
The glass in thread, cord, or wire like formation may be round or angular
in cross section, and the windings may be in contact or open with tacking pieces
here and there to hold the spiral windings together or at distances apart, and
in some cases prismatic effect can be obtained for enhancing the effect when such
a Globe or Chimney is in use. If the spirals be open, say, at intervals, the
spaces will serve for the passage of air to not only keep the Globe or Chimney
cool but admit of the flame being supplied with a fresh supply of Oxygen to
support combustion.

Improved Manufacture of Globes and Chimneys for Gas and Oil
Lamps.
I, JAMES STOTT, of Vernon Works, Lee Street, Oldham, County of Lancaster,
Gas Engineer, do hereby declare the nature of this invention 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 for object, improved manufacture of Globes and Chimneys
for Gas and Oil Lamps.
For the purpose of my invention, I employ soft hot glass in thread, cord, or
wire like form and wind it on a mandrel or pattern and cause it to conform to
the shape of same.

page_text: The glass need not be of the same colour since various colours of glass can be
used for the purpose according to the desired artistic appearance of the Globe
or Chimney that has to be produced.
The glass in thread, cord, or wire like formation may be round or angular
in cross section, and the windings may be in contact or open with tacking pieces
here and there to hold the spiral windings together or at distances apart, and
in some cases prismatic effect can be obtained for enhancing the effect when such
a Globe or Chimney is in use. If the spirals he open, say, at intervals, the
spaces will serve for the passage of air to not only keep the Globe or Chimney
cool but admit of the flame being supplied with a fresh supply of Oxygen to
support combustion.
My invention will be well understood by the aid of the annexed drawings in
which at Figure 1 I show a Gas or Lamp Globe of circular glass wire, cord, or
thread spirally wound and provided with internal vertical strips but said strips
may be external or both internal and external, said strips being of glass or
metal as desired.
Figure 2 section of Gas or Lamp Chimney similarly arranged.
Figures 3, 4, 5 6 7 and 8 are sectional diagrams of plain Gas or Lamp Chimneys
illustrating the various shapes of glass thread, cord, or wire, such as square,
triangle, oval, hexagon, or other and with both internal and external vertical
cords, wires, or threads of glass, or other incombustible material which locate or
keep the spirals in their superposed order.
A, are the spirals, B, the vertical fixings and these may be of glass or of metal
wire, if of glass whether the spirals be open i.e. at a slight distance apart to
admit fresh air to the flame for supporting combustion in addition to that supplied
from the gallery or other support, or whether cach spiral is in touch with the
next, or spaces be left at the lower portion of the Globe or Chimney in which
casc air can enter the open spirals from near the bottom only, the upper part
being in close contact to induce an up current without causing a flickering or
jumping of the flame from sudden draughts.
The vertical threads B can be connected to the spirals at any part by the blow
pipe, and if metal be used the ends can be clamped.
I have referred to my invention as if the whole of the Gas or Lamp Globe or
the Chimney be made of continuous spirals but such Globes or Chimneys may be
made in sections and the parts be cemented up by the blow pipe or otherwise.
Having now particularly described and ascertained the nature of this Invention
and in what manner the same is to be performed I declare that what I claim is :-
1. The improved manufacture of Globes and Chimneys for Gas and Oil Lamps
in the manner described and substantially as shown on the annexed drawings.
2. The manufacture of Gas and Lamp Globes and Chimneys from thread, cord,
or wire like form of Glass, substantially as specified.
