Improvements in the Manufacture of Galleries for Gas and other
Lamp Globes and Chimneys.
I, WILLIAM THOMAS SUGG of Regency Street in the City of Westminster,
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:-
The chief object of this invention is to produce, in a simple and economical
manner, the galleries which are used with gas burners for supporting the glass
globes, whether the wide mouth globes now so common, or the old-fashioned narrow
mouth globes, but the invention can also be applied to the production of galleries
for argand chimneys, and for lamp chimneys generally.
To this end, the invention consists in the mode of manufacturing these galleries.
In the accompanying drawing,
Figure 1 is a plan view of one arm of a gallery for a wide mouth gas globe,
Figure 2 is a side view, partly in section, of the gallery, and Figure 3 is a plan
view. Figures 4 and 5 are respectively a plan view and a side view of a gallery
of the old-fashioned type of gas globe.
In carrying out my invention, as applied to a wide mouth gas globe, I form
the gallery from sheet metal, and each arm, which is stamped out by suitable
dies, consists of a bracket a and a ring or eye, Figure 1. The bracket a is then
twisted at the neck a¹ to assume a position at right angles to the ring or eye b.
At the same time that each arm is stamped out, may stamp three holes in the
eye at equal distances apart, as shewn at c, Figures 1 and 3, or these holes may
be afterwards formed.
I then take three arms thus prepared, and place their eyes one on the other,
with the holes c coinciding, and the brackets at the proper angles, and rivet the
eyes together, as shewn at Figure 2.
It will be obvious that the eyes may be secured in any other well-known
manner.
I next thread the inner periphery of the boss formed by the three superposed
eyes, so that the boss may be screwed onto the burner or body of the lamp, and
the gallery is complete.
In Figures 4 and 5, the twisting at the neck will be unnecessary, and the end
clips d for holding the flange of the globe, as well as the lug e for the holding
screw f, may be formed by hand, or in any convenient manner. In like manner
the galleries for argand and other lamp chimneys will be produced, the slight
modifications necessary being obvious to any one conversant with the art.
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 manufacture of galleries for gas and other lamp globes and chimneys
as herein shown and described, and consisting in stamping out the arms in one

page_text: piece, securing two or more together at proper angles, and threading the inner
periphery of the boss formed as set forth."
2. The manufacture of galleries for gas and other lamp globes and chimneys
as herein shewn and described, and consisting in forming each arm of a bracket
and eye in one piece by stamping twisting the bracket at right angles to the
eye; placing the eyes together at the proper angle; and securing them to form a
boss; & threading the inner periphery of the boss as set forth.
3. Forming galleries for gas and other lamp globes and chimneys from sheet
metal as herein shewn and described.
