WILLIAM BLENHEIM of Englefield Green Egham, Surrey Electrical Engineer, do
hereby declare the nature of this invention to bo as follows:-
A dynamo or magneto-electric generator worked by a falling woight, spring or
other contrivance which would effect the same purpose, the armature of which
generator is held in a position of rest by an escapement connected with a clock or
other timekeeper, which at any required periodical intervals liberates the escapement
thereby allowing the armature to revolve and so generate an electric current. These
currents are used by means of other ordinary magnetic apparatus to propel simul-
taneously a number of other clocks.

page_text: WILLIAM BLENHEIM Englefield Green Staines Electrical 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 arrangement consists of a magnoto-electric generator or dynamo driven by a
weight or spring. Figures 1. 2. & 3 will assist in explaining it, Figs. 1 & 3 being the
two end views and Fig. 2 the side view. "A" is an end view of the armaturo
known as "Siemens armature
"but
any form of armature may be used. "B" are
permanent steel magnets. "C" an escapement. "D" a lever to liberate the escapo
wheels with an oscillatory motion. "E" a weight. "F" a train of wheels.
The action of the apparatus is as follows:-The weight is wound up similarly to an
ordinary clock weight and held in position by the escape "C" resting against a stop
on the lever D. If the lever is now moved by any means either backwards or
forwards it will allow the weight "E" to descend and the armature "A" will revolve in
the magnetic field produced by the magnetic poles N. S. till it is checked by the
other end of the escape coming against the stop. In this caso it will make half
a revolution and a current of electricity will be induced in the coils of wire
surrounding the armature, which by means of wires can be conveyed to other
clocks at a distance and which can thus be worked in sympathy with the above
apparatus.
These sympathetic clocks would consist of a train of wheels worked by a ratchot
and a pawl driven by a magnet or may be worked also by magnetic needles moving in
a coil of wire or by other means. The electric current induced in the armature "A"
would give a simultaneous motion in each of the other clocks, no weight nor
pendulum being required. The end of the lever D is connected with any ordinary
clock and by means of a cam or similar arrangement the lever would be made to
oscillate at certain intervals of say each second, minute &c.
As before said, any kind of armature may be used which may be wound with
several coils of wire. It may also turn the whole revolution or a fraction of the
revolution as circumstances may require.
In some cases it would be better to avoid the use of the separate train of wheels,
escapement and lever as before described and to combine the magneto-generator
with an ordinary clock. The armature A would be fixed on the escapement wheel
spindle or any other spindle in the clock and the ordinary clock escapement would
then liberate at intervals the armature as above described the ordinary clock weight
or spring providing the necessary power.

page_text: 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 use of a magneto-electric generator or dynamo driven by a weight,
spring or any other contrivance and its motion regulated by means of a clock for the
purpose of driving electrically and simultaneously other clocks.
(2) A magneto-generator attached to, and driven by the same clock for the purpose
as named in claim 1.
