An Improved Electric Circuit Closing Device.
I, CARL ADOLPH HOLLSTEIN, Civil Engineer, of 21, Neuegasse, Dresden, in the
German Empire, do hereby declare the nature of this invention to be as follows :-
My invention relates to an improved electric circuit closing device, and has
for its object the completion of the circuit of electric lamps at a predetermined
time by the operation of a clock.
My invention consists in providing the falling weight of an alarm or other
clock insulated by a silken or other cord by means of which it is hung, such falling
weight being provided with a conical or other shaped extremity which, upon the
weight falling into its lowest position, contacts with complementary surfaces of
corresponding conical shape, which form. the terminals of a circuit, and by which
on the interposition of the falling weight, which is a good conductor of electricity,
the circuit is completed.
I do not limit the application of my invention to circuits of electric lamps, as it
is obvious that the invention may be applied to other purposes in which an electric
circuit is employed.

An Improved Electric Circuit Closing Device.
I, CARL ADOLPH HOLLSTEIN, Civil Engineer, of 21, Neugasse, Dresden, in the
German Empire, 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 :—
My invention relates to an improved electric circuit closing device, and has for
its object the completion of the circuit of electric lamps at a predetermined time
by the operation of a clock or other similar suitable mechanism. My invention is
illustrated in the accompanying drawings, in which Figure 1 illustrates in
diagrammatic elevation a circuit closing device provided according to my invention,
while, Figure 2 is a plan corresponding thereto."
My invention consists in providing the falling weight G of an alarm or other clock
or mechanism insulated by a silken or other cord as S by means of which it is
hung, the falling weight G being provided with a conical or other shaped
extremity G', which on the weight & falling into its lowest position contacts with
[Price 8d1

page_text: the complementary surfaces such as T T of corresponding conical or other shape
which form the terminals of a circuit, and by which on the interposition of the
falling weight G, which is a good conductor of electricity, the circuit is completed.
In the drawing the falling weight is illustrated in its initial position by dotted
lines and is further represented in position in close proximity to the'terminals T T¹.
I do not limit the application of my invention to circuits of electric lamps, as it
is obvious that the invention may be applied to other purposes in which an electric
circuit is employed.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
•
An improved electric circuit closing device, in which the circuit is completed at
a predetermined time on the operation of a clock or similar suitable mechanism,
causing the fall of a weight which completes the circuit substantially as described.
Dated this 21st day of January 1898.
