A Keyless Winding and Pointer Adjusting Mechanism for Watches
with Fusee Wheels having a Disengaging Device Operated
Automatically when the Watch is Wound up.
I, NATHAN SILBERBERG, of Jassy, in the Kingdom of Roumania, Horologists
do hereby declare the nature of this invention to be as follows:-
This invention relates to a self-winding or pointer adjusting mechanism for
watches with a fusee wheel having a device disengaging the winding mechanism
operated automatically as soon as the watch has been fully wound up.
The construction of the mechanism to carry my invention into effect is as
follows. Arranged in a recess on the plate there is affixed to a square arbor of
the fusee a single toothed wheel and adjoining a partly indented and partly blank
stop-wheel as is usual to permit a certain number of revolutions of the fusee. Upon
the blank part of the stop wheel is provided an eccentric projection and a cam
tooth which eventually will come home upon a stop pin.
At the same level with this stop wheel is a spring pressed pivotted lever pro-
vided with a detent or pawl which engages against one or two projections of a
spring pressed pivotted cam piece secured to the axis of a scythe-shaped lever the
end of which projects from the side of the watch case for manual operation as
hereinafter more particularly described.
Over the aforesaid stop motion is fitted a pair of geared wheels mounted on a
plate pivotted at the centre of that wheel which gears into a crown pinion fixed to
the winding arbor projecting through the side of the case.
This pivotted plate is provided with two projections right and left, one of which
is pressed by a spring and the other engages upon cam points of the boss of the
aforesaid scythe-shaped pivotted lever.
When the said scythe-shaped lever is in normal position within the case its
pressure upon one of the wings of the said pivotted gear plate causes the gearing
from the said winding arbor to occupy an intermediate position between a toothed
wheel upon the arbor of the fusee on the one side and a toothed wheel com-
municating by suitable gearing to the hands of the watch situated on the other
side of the said pivotted plate.
When it is desired to wind up the watch the said scythe-shaped lever is pulled
so as to project a short distance beyond the edge of the watch-case which has the
effect of permitting the spring pressure upon the aforesaid pivotted gear-plate to
bring a lower gearing wheel into gear with the toothed wheel upon the arbor and
the watch may be thus wound up from the winding arbor. As however the stop
mechanism revolves from the arbor fusee the aforesaid eccentric projection on the
stop wheel moves the aforesaid lever and throws out the detent holding the scythe-
shaped lever temporarily in its desired position. When this happens, the scythe
lever is released and a spring pressing upon it, which is stronger than the opposing..
spring action on the pivotted gear plate, causes the gearing wheel once more to be
disengaged from the toothed wheel on the fusee.
When it is desired to adjust the pointers of the watch the aforesaid scythe-shaped
lever projecting from the edge of the case is pulled out to its fullest extent and a
cam finger upon the boss of the said scythe lever throws over the gearing wheel on
the said pivotted plate so as to cause it to engage in a toothed wheel on its opposite
side communicating by suitable gearing with the pointers of the watch. A further
projecting nob connected to the detent lever temporarily locking the scythe lever
in the required position has been caused to project by the aforesaid motion. When
the pointers have been properly adjusted by the turning of the said winding arbor,

page_text: the operator may push back the aforesaid stop wheel, releasing the locking of the
scythe-shaped lever and a spring reaction causes the apparatus to once more resume
normal position with the winding arbor out of gear until again required.

A Keyless Winding and Pointer Adjusting Mechanism for Watches
with Fusee Wheels having a Disengaging Device Operated
Automatically when the Watch is Wound up.
I, NATHAN SILBERBERG of Jassy in the Kingdom of Roumania, Horologist
do hereby declare the nature of this invention and in what manner the saine is to
be performed to be particularly described and ascertained in and by the following
statement :-
This invention relates to a self winding and pointer adjusting mechanism for
watches with a fusee wheel having a device disengaging the winding mechanism
operated automatically as soon as the watch has been fully wound up.
The construction of the mechanism to carry my invention into effect is as
follows:
In order that my invention may be the better understood I will now proceed to
describe my invention, in relation to the drawings hereunto annexed reference being
had to the letters and figures marked thereon.
Figures 1 and 2 show the mechanism in its normal position.
Figure 3 shows the mechanism in the position corresponding to that for winding
the watch and
Figure 4 shows the same in the position for adjusting the hands.
:-
The construction of the mechanism as shown in Figures 1 and 2 is as follows:-
The parts shown in Figure 1 are arranged in a recess a of the plate. In this
figure, A shows the winding spindle and B an adjusting tooth situated on a square
arbor of the fusee. The adjusting wheel C has an eccentric baud a cam tooth b³.
A pin ³ fixed in the plate is arranged close to the adjusting wheel C.
The lever with the detent or pawl c is pivotted to the plate by means of a
screw. A spring d presses the pawl c¹ against a piece e having two teeth or pro-
jections one of which is pointed and the other square. The end of a spring ƒ
enters into a recess in the piece e and presses the latter beside the detent or
pawl c¹.
The parts shown in Figure 2 are attached to the upper face of the plate by
means of screws and nearly cover the parts shown in Figure 1. On the square of
the winding spindle A, see Figure 2, is situated the pinion gearing through an
opening in the plate into the wheel y' which gears into the wheel g².
8
The wheels and are situated on a steel plate having two arms l'1, and fixed
to the plate by means of a screw a carried through the wheel g¹ and the steel
plate, so that the latter with the wheels g¹³ can be rotated around the screw a'.
A wheel is situated on the square arbor of the fusee over the adjusting tooth B
and a wheel gears into a change wheel of the hand mechanism. The spring h
presses the arm 12 of the plate towards the pin m and makes the wheels 93 and 9³
gear into each other when desired, so that the watch may be wound up. An
angularly shaped lever carrying projections k, k, k2 is attached to the piece e
(Figures 1 and 2) by means of two pins, and the piece e with the said angular
lever is pivotted to the plate by means of a screw. As shown in Figure 1, the
spring presses on the piece e and therefore acts on the angular piece k, k', k
attached to the piece e. The said angular lever presses with the projection k¹ on
the arm and therefore maintains the wheel between the winding wheel 9 and
the hand wheel j (Figure 2).

page_text: The winding up of the watch is effected in the following manner.
The angular piece is pulled out of the watch casing as shown in Figure 3. The
pawl cis therefore moved into the recess between the square and pointed teeth of
the piece e by the pressure of the spring d. At the same moment the arm of the
plate enters a recess between and of the angular piece, and by the pressure
of the spring on the arm the wheels g³ and g³ are made to gear with one another
so that the watch can be wound up.
When the watch has been fully wound up and before the cam or tooth 6* arrives
at the pin 63, to prevent the further winding up of the watch, the eccentric part b¹
of the adjusting wheel presses against the pawl lever c² and moves the latter such
a distance as to draw the pawl out of the recess of the piece e. The spring f
which is stronger than the spring then presses the angular piece so far around
the screw a that the side k¹ of the recess of the angular piece presses the arm
out of the recess, whereby the plate is turned round the screw a¹ and the gearing
between the wheels 993 is interrupted so that the rotation of the winding pin A is
transmitted only to the wheels yg g², and not to the wheel 9. This is effected as
follows:-
The end of the arm is cut off obliquely so that when the plate 7 is in the
position shown in Figure 3, and after disengagement of the ratchet pawl c¹ from
the piece e, the pressure of the spring effects a rotation of the piece e with the
angular lever kk¹³ causing the latter to return to the position as in Figure 2, the
horn k' of this angular lever sliding over the oblique end of land in consequence
pressing the latter away in a direction at right angles to the oblique face of 1.
The oblique faces of the arm is formed so that a line drawn perpendicular to
this flat oblique plane, falls below the screw d therefore the before mentioned
pressure of on the oblique end of causes a rotation of the plate e' away from a³
thus disengaging the cog wheel g' from the wheel g³, leaving the plate in a central
position as in Fig. 2 the wheel g² not engaging with either g or j.
For the adjustment of the hands the angular lever with projections k¹³ is also
used as hereinafter described.
The angular piece is pulled out of the casing at k, the pawl c¹ falls then behind
the pointed tooth of the piece e and at the same time the angular piece pulls the
arm downwards at k³, so that the plate turns around the screw a thus making
the wheel gear into the adjusting wheel to allow of the hands being rotated by
the turning of the winding spindle A. By finger pressure on a sliding piece s
arranged below the plate and which presses on a screw of the pawl lever c³, the
pawl is pressed away from the piece e and the springs and h place the wheel g
back between the wheel 93 and j but gearing into neither so that the fusee as well
as the hand mechanism are no longer connected with the winding mechanism.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1st. A keyless winding mechanism with fusee consisting of a pivotted plate /
carrying two wheels g¹g², such plate / having two arms l', and its normal position
being in the middle between the hand wheel and the winding wheel g³ situated on
the fusee in combination with a spring / acting on an arm an adjustable angularly
shaped lever having projections k, k₁, k³, acting on the arm and carrying a piece e
rotating with it and spring pressed by a spring f, a pawl lever c³ acted upon by a
spring and carrying a pawl c' entering into or between the teeth of the said piece e
thus holding the angularly shaped lever with projections k, k¹, k³, in its various
positions, substantially as and for the purposes described.
2nd. In the mechanism as claimed in Claim 1.
a. An adjusting wheel C with an eccentric b¹ which, when the watch is being
fully wound up turns the pawl lever c* around its axis, so that its pawl cl
is placed out of contact with the teeth of the piece e, the action of the

page_text: spring on the piece e-and the angular piece kkk inducing the latter to
move the arm, substantially as described and illustrated..
"
b. The sliding piece s arranged below the plate, by which the pawl e is
removed from the piece e so that the springs and return the plate / into
its former position, substantially as described and illustrated.
