I ERNST JULIUS HEMPEL, of 33 Grosse-Plauenschestrasse, Dresden, Saxony, in
the Empire of Germany, Locksmith, do hereby declare the nature of my said invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The object of my invention is to provide improved means and appliances for
opening, closing and securing the glass shades or globes of Wenham lamps, and
lighting and otherwise manipulating the same.
And in order that my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is an elevation of a Wenham lamp, showing the glass globe opened, with
my invention applied thereto. Fig. 2 shows the same closed. Fig. 3 is a side view
of the upper end of the rod and its attachment, and Fig. 4 is a view of the same, at
right angles to Fig. 3. Figs. 5 and 6 are detail views.
a is the lamp, is the burner, c the glass carried by the ring frame d, hinged at e.
fis the locking bar, which locks the frame d to the catch 9 of the lamp. is a small
ring formed with trunnions or pins ii and fitted with a set screw k; (shown
enlarged in Figs. 5 and 6). This ring is fixed to the locking bar f, as shown in Figs. 1
and 2.
m is the upper end of a rod or handle, which may be of any suitable length to
enable the operator to manipulate the lamp, without the aid of a ladder.
A metallic ferrule n is fitted to m, and three metallic wires ooo (preferably of
The three wires are
steel or iron) are soldered or otherwise fixed to the ferrule n.
Above this one of the wires is
bent inwards and united by the ring p, as shown.
utilised to support a small lamp r, for lighting the gas, and the other two wires are
bent at 8. as shown, to form bearings for the pins ii, when using the apparatus.

page_text: In order to open the glass globe e for the purpose of lighting the lamp, the
rod m is held in the hands. The bearings ss are then placed under the pins i i,
as shown in Fig. 2, whereby the catch is readily disengaged, and the glass is
lowered gently, to the position shown in Fig. 1.
The small lamp may then be used to light the gas, and the glass is again
raised and fastened by the same means.
The small lamp may be dispensed with for Wenham lamps baving self-lighting
gas jets.
The hooked end t is provided for opening and closing the main or local gas taps,
and to regulate the supply to the lamp.
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 improved device for manipulating Wenham gas lamps consisting of the rod
or handle m, fitted with the wires o the bearings s, the lighting lamp, and the
hook t, used in combination with the ring h, pins ii and set screw k fitted to the
locking bar f of the lamp, substantially as herein before described and illustrated by
the drawings.
2. The general construction, combination, and arrangement of the several and
respective parts, together forming my invention of an improved device for opening;
closing, and securing the glass shades or globes of Wenliain lamps, and lighting and
otherwise manipulating such lamps, substantially as herein before described and
illustrated by the drawings.
