I, IGNAZ HERRMANN, Watch-maker, of 23, The Parade, Lordship Lane. Dulwich,
Surrey, do hereby declare the nature of this invention to be as follows:-
The improvement consists in an arrangement, by which the wheel that is attached
to the winding square of the fusee, rotates only in one direction; that is during
winding, having no motion during the time of the going of the watch or Chronometer,
or in the interval between two consecutive windings. Thus no contrivance to throw
the gearing into this wheel out of action during the said interval; and hence any
going barrel keyless mechanism can be applied in the following manner :-
The wheel gearing into the centre pinion rides loose on the arbor that carries the
winding wheel.
This arbor has a small wheel attached on the fusee side, which gear into two others,
the centres of which are fixed in the cone of the fusee, and these again gear into
internal of the wheel that acts into the centre pinion or the great wheel-the three
wheels and the internal teeth of the great wheel lying within access of the cone of the
fusee.
The cone forming the fusee, also rides loose on the winding arbor:-thus the
winding arbor moves only during winding, by which the improvement in the keyless
mechanism is effected.
The action for setting the hands is effected by a cam. The centre of a wheel
gearing into the wheel on the winding arbor is attached to a plateform, which is
moveable by a cam action, thus the driving wheel is thrown in gear with the hands.

I, IGNAZ HERRMANN 23 the Parade, Lordship Lane Camberwell, Surrey, Watch
and Clockmaker 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 improvement consists in an arrangement, by which the wheel, that is attached
to the Winding Square of the fusee, rotates only in one direction, that is during
Winding, having no motion during the time of the going of the Watch or Chronometer,
or in the interval between two consecutive Windings; thus no contrivance to throw
the gearing of the wheel on the fusee arbour out of action during the said interval is
needed, and hence any plain going Barrel-Keyless mechanism can be applied.
The contrivance is effected in the following manner.
The Fusee and great wheel, that is the wheel gearing into the adjacent pinion, ride
loose on an arbor F. III.
The great wheel R. F. I and F. IV has both, the ordinary teeth, and also a rim of
teeth at right angle to its plane; the wheel rides loose on the arbor F. III.
A toothed disk B, is attached to the arbor, either by a screw or some other
convenient manner. This disk gears into two other toothed disks A, D, which rotate
on two arbors a, a, F. V, which are fixed into the cone of the fusee, and these again
gear into the toothed rim R of the great wheel, and so form an Epicyclic train. Thus
as B F. I rotates, and the rim R remains stationary, the fusee is carried with it
during winding; and during the going of the Watch, the great wheel is acted on by
the toothed disks A, D riding loosely on the arbors a a F. V. The relative position
of great wheel L, and arbor H are shown in F. II.
E, F. II is a cap, attached to the fusee, for steadying its position and also fixing it
in the fusee, by a screw, running into a groove of the arbor, or some other convenient
manner.
In F. VI, M represents the wheel gearing into the driving shaft of the Pendant N,
the wheel mounted on the fusee arbor and C, P, K, the ordinary cannon pinion,
minute wheel, and intermediate wheel, for connecting the wheel M with the set hands
motion, as in the ordinary going Barrel arrangement, or as its application to a Watch
of any particular construction may require.
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 :
1st. A Keyless mechanism for Fusee Watches and Chronometers, that requires no
disconnecting action after the winding, and during the going of the Watch or
Chronometer.
2nd. A Fusee that requires no return motion for its winding square or arbor.
3rd. The application of this keyless motion to any key winding Watch or Chro-
nometer.
