Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both
in the County of Lancaster, and 323, High Holborn, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention to be as follows:-
On the accompanying drawing,
Figure 1 is an elevation of the improved motor showing also the connecting gear.
Figure 2 is an elevation of a portion of the motor at right angles to Figure 1.
Figure 3 a detail view.
G is the box or case of a clock. On the axle a is placed a disc C with a vertical
edge p into which engages a levere e with two notches k. f¹ is a second lever. These
levers are joined together by a spring h. As soon as the spring is contracted the
lever e is squeezed or clinched with its notches into the vertical edge p and turns
the axle a in the direction of the arrow. This motion is communicated to the
clockwork.
AA is an electro-magnet provided with the armature B. Upon this armature is
fixed completely isolated a projecting arm K bearing the support 9 in which is fixed
the screw H. I is an adjusting screw.
C is an ordinary or permanent magnet on which is fixed the support D for the
lever E isolating upon the fulcrum f. The right arm of the lever E is strengthened
by an isolating plate.
As soon as the clock is put in motion, the spring h by contracting itself acts upon
the lever e e which turns the axle a in the direction of the arrow. Consequently the
connecting-rod z (and at the same time the armature B) is lifted. The left arm of
the lever E then approaches the magnet C until it is completely attracted. Then the
current is closed and the electro-magnet A attracts again the armature B. Con-
sequently the arm K and connecting rod z also are going down, the current is
interrupted and the same action re-commences.

COMPLETE SPECIFICATION.
Improvements in or relating to Electrical Motors for Olooks and
similar Apparatus.
A communication from abroad by GÜNTHER and LOUIS HOPPE, of Cöthen, in the
Empire of Germany.
I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool and 6, Bank Street, Manchester, both in
the County of Lancaster and 323 High Holborn, in the County of Middlesex, Civil
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 invention relates to electrical motors for clocks and similar apparatus, and has
for its object a motor in which the power of an ordinary or permanent magnet is

page_text: utilized to actuate a vibrating arm in one direction in such a manner that on the end
of its stroke an electric circuit shall be automatically closed which energizes an electro
magnet the power of which is used to return said vibrating arm. The arm being thus
vibrated, the clock or other mechanism is actuated by means of suitable connections
hereinafter described. On the drawing accompanying the provisional specification
Figure 1 is an elevation of the improved motor showing also the connecting gear.
Figure 2 is an elevation of a portion of the motor at right angles to Figure 1.
Figure 3 is a detail view.
G is the box or case of a clock. On the axle a is placed a disc C with a vertical
flange or edge p into which engages a lever e e with two notches k. A spring
constantly tends to depress the end of the lever e. As soon as the spring is contracted
as hereinafter described the lever e is squeezed or clinched with its notches into the
vertical edge p and turns the axle a in the direction of the arrow. This motion is
communicated to the clockwork. Any suitable detent may be employed to prevent
the disc turning in the reverse direction.
AA is an electro magnet provided with the armature B. Upon this armature is
fixed completely isolated a projecting arm K bearing the support g in which is
fixed the screw H. I is an adjusting screw.
C is an ordinary or permanent magnet on which is fixed the support D for the
lever E oscillating upon the fulcrum f. The right arm of the lever E bears an
isolating plate x.

As soon as the clock is to be put in motion if the parts are placed as in Figure 1
and then released the spring h, by contracting itself, acts upon the lever ee which
turns the axle a in the direction of the arrow. Consequently the connecting-rod
(and at the same time the armature B) is lifted. The left arm of the lever E
then approaches the magnet C' until it is completely attracted. Then the current
is closed and the electro-magnet A attracts again the armature B letting the end
of the arm E leave the magnet and thus breaking the circuit. Consequently
the arm K and connecting-rod z also are going down, and the same action re-
commences. The axle a may be connected by means of any suitable gearing with
the clock or other mechanism which it is desired to actuate.
Having now particularly described & ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is :-
1. An electrical motor for clocks or similar apparatus, having a disc ( with vertical
flange or edge p fixed on the axle a a of the apparatus in combination with the levers e
and fand the spring h, substantially as described and shown.
2. In an electrical motor for clocks or similar apparatus, an ordinary magnet C' in
combination with an electro-magnet A and lever E, the oscillations of said lever
alternately making and breaking the circuit, and, by means of suitable connections,
imparting motion to the apparatus, substantially as described and shown.
