COMPLETE SPECIFICATION.
Automatic Winding-up Apparatus for Motors Actuated by Springs
or Weights.
I, FREDERICK WILLIAM GOLBY, 36, Chancery Lane, in the County of Middlesex,
Patent Agent, do hereby declare the nature of this invention and in what
manner the same is to be performed, as communicated to me by Ernst Emile
Rühle, of Wurzen, Saxony, Germany, Watch and Clock Maker, to be particularly
described and ascertained in and by the following statement:—
This invention relates to automatic winding up apparatus for spring and
weight motors such as are employed in watches, clocks, musical instruments and
the like. The automatic winding up of the motor is according to this invention
produced as follows:-Before the mechanism which is actuated runs down, it
closes an electric circuit, in which is an electro-motor that winds up the motor
actuating mechanism. By suitable means the circuit is kept closed only so long
as is necessary for the winding up operation.
The accompanying drawing illustrates the invention as applied to a clock-work
mechanism actuated by springs.
"
The clock-work mechanism, together with the winding up apparatus, is pre-
ferably enclosed in a casing. A clock-work mechanism with striking apparatus
is given as an example.
The electric circuit, which contains a sufficiently powerful source of electricity,
preferably dry elements a, and the small electro-motor which effects the winding
up extends to the clock casing, and ends in a contact closing spring placed
thereon.
This contact spring a projects at its free end into the path of a pin e mounted
on the hour wheel of the clock-work mechanism. Thus every 12 hours there
will be a closing of the circuit through e and e and the electro-motor will be
actuated.
The time during which the circuit remains closed is easily regulated by
adjustment of the length of the end of the contact spring c which comes into
contact with the pin c.
As, in order to avoid any interruption, or interference, in the action of the
springs it is desirable to arrange the electromotor b at a considerable distance
from the clock-work mechanism the actuating of the winding-up mechanism is
effected by the latter through the medium of belt pullies. The belt f runs
over a driving pulley g on the shaft of which is seated a toothed wheel h, which
by means of intermediate wheels, i, k, l, and m actuates one of the spring boxes
or barrels n for example, from which the motion is transmitted by an inter-
mediate wheel o to the other spring box or barrel p.
A clock furnished with this automatic winding-up apparatus will go without
intermission as long as current is delivered from the source of supply.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. Automatic winding-up apparatus for moters actuated by springs, or weights,
the distinguishing feature being that before completely running down the
motor mechanism effects the closing of an electric circuit, in which is an electro-
motor b, and so keeps it until the latter, by means of suitable gearing, has
effected the re-winding of the motor mechanism substantially as described.
