An Improved Device for Winding up Clocks or Clock-works.
I, PAUL EIBIG, of 16, Annenstrasse, Berlin, in the Empire of Germany, Mechanic,
dc hereby declare the nature of this invention to be as follows:-
By this winding up device several clock-works can be wound up simultaneously
by one and the same mechanism at equal intervals, and the working of these clock
works is effected with an equal driving power which can be regulated according to
necessity. The clock works can have different velocities and the winding up
mechanism can be operated mechanically as well as electromagnetically.
In the annexed drawing a form of construction for the above mentioned purpose
is represented for two clock-works which receive their impulsion simultaneously
by means of an electromagnetically operating winding mechanism. Fig. 1 is an
elevation Fig. 2 a plan and Figs. 4 and 6 are sectional views of the mechanism.
Figs. 3 and 5 are detail views of parts of the mechanism.
Suppose, that two clocks works are united in one apparatus, of which the one
shows for instance exactly the right time, whilst the other one has at times an
increased velocity, as for instance is the case in electricity meters with direct
current indication.
The essential parts of the work consist of (I) a contact or winding mechanism;
(II) a clock work working with variable velocity; (III) a clock work for instance
with constant velocity.
The winding mechanism may be so constructed that by means of a contact the
circuit of an electro magnet remains closed for some time, for instance every
minute for a few seconds and effects in the mean time the winding of the two
clock works, but during the remaining greater part of this minute period the circuit
is broken. This contact work operates in such a manner, that on the axle 1 of
the clock work II working with variable velocity there is a cam disk 2 which at
cach revolution moves a lever 4 turning round the axle 3 periodically up and down
and operates the electromagnetic contact mechanism by means of the nose 6 of this
lever which acts as a detent. The contact mechanism consists of a spiral spring 8
fixed with its inner end upon the axle 7, the outer end of this spring being fixed on
the spring barrel 9. On the axle 7 is a ratchet wheel 10 with pawl 11, which wheel
is pushed one tooth forwards by a dog 12 during the movement of the clectro
magnet armature 18 together with the rod 14 connected movably with the same at
each attraction of the armature.
The axh 7 winds the spiral spring 8 from the interior end. The running down
of the pring 8 is regulated by the spring box 9, that is, the exterior end of the
spring operates on a driving wheel 16 by means of a toothed wheel 15. On the
axle 20 of this wheel 10 is also a double lever 17 (Fig. 4) which carries 2 pins 18
& 19 at unequal radial distances. These pins 18 & 19 are stopped alternately by
the nose 6 of the lever 4.
Each time when the point 5 of the disengaging lever 4 sliding on the cam
disk 2 during the revolution of the axle 1 has nearly reached the highest point of

page_text: this disk a pin for instance 18 is freed by the nose 6 of the lever 4. The wheel 16
and the arm 17 turn half a revolution until the pin 19 is stopped by the noso G.
On the driving axle 20 is also an eccentric 21 which at the said position of the
axle 1 moves the eccentric frame 22 to the left and brings the contact arm 23 into
contact with the contact piece 24. The circuit of the electro magnet 25 is thus
closed and when the electro magnet armature 13 is attracted the dog 12 on the
arm 14 of the armature pushes the ratchet wheel 10 as already mentioned one tooth.
to the right and thus the spring 8 is wound. The contact 23, 24 remains closed
only for a short time (for instance 3 seconds) until the point 5 of the lever 4 falls
down the vertical face of the cam disk. At this moment the pawl 19 is freed by
the upward movement of the nose 6 of the disengaging lever 4 and the double
lever 17 runs again half a revolution until the pin 18 is stopped by the nose 6.
From that moment, that is to say, during the upward stroke (for instance
57 seconds) of the point 5 of the disengaging lever 4, the driving axle 20 remains
in the position, in which the eccentric disk 21 keeps the contact 23 out of contact
with 24 by means of the frame 22, that is to say, the current of electro magnet 25
remains interrupted during this longer period.
By the arrangement, that the operations of the contact and winding mechanism 1
are exactly regulated in this manner by the working of the clock work II secure
operation is also guaranteed for working with reversed current in consequence of
the circuit closure not being effected momentaneously but for a measurable time
adjustable at pleasure (for instance a few seconds).
There remains to be explained the manner of operation of the winding
mechanism on the two clock works II and III running with different velocities.
As already described the axle 1 of the clock work I operates the electro
magnetic winding mechanism at regular intervals, for instance in the drawing
after each revolution of the axle 1. Therefore at each operation of the winding
mochanism the clock work II would have made an equally long course.
axle 1 of the clock work II is a ratchet disk 26, the operation of which is described
hereinafter and a driving wheel 27 which gears with a wheel 28.
On the
The real winding action by the electro magnet or a mechanically driving power
(for instance main driving spring) does not operate directly, but for instance by
means of a differential gear on the going work of the clock work II for the purpose
of avoiding disturbing influences on the working by the periodical operations of
the winding mechanism and in order to have at disposal an intermediary power
(spiral spring or weight) regulatable according to necessity.
As represented in Fig. 2, the oscillating going parts of the clock operate the
revolution of a bevelled wheel 30 by means of the toothed gear transmission 27, 28
and the shaft 29. The bevelled wheel 31 rolls on the bevelled wheel 30, moving
simultaneously planet like round its own axle 32 and round the through passing
axle 29 for a small angle downwards under the power of the running down inter-
mediary weight or the intermediary spiral spring 34.
This intermediary spring 34, which as may be seen, operates immediately on the
going work, can then be easily arranged to be regulated for obtaining the desired
width of swinging and in consequence of the differential transmission it is again
wound at equal intervals, without the impulsion of the clock undergoing dis-
turbance. This is effected in such a manner that the armature 13 of the electro
magnet when attracted, moves the arm 37 for a certain distance forwards and
pushes the ratchet wheel 35 one tooth forwards by means of the dog 36 on the
arm 37. The ratchet wheel 35 which cannot move backwards represents thus the
main driving force of the work which can be impelled as well electromagnetically,
as described, or mechanically and is connected solidly with the bevelled wheel 33
but is arranged with the same to turn freely on the axle 29. The bevelled wheel 33
is then in gear with the planet wheel 31 etc. and at each forward push of the ratchet
wheel 35 for one tooth it causes an equal lifting of the arm 32 in consequence of
the upward rolling of the planet wheel 31 and thus a tensioning of the intermediary
driving spring 34 for an always equal amount. This operation of the intermediary

page_text: driving work is thus repeated at regular periods, which for instance as in the
drawing, correspond to one revolution of the axle 1 of the clock work II. During
this period each time at the short attraction of the armature the ratchet wheel 35
is turned forwards for one tooth, whereby the intermediary spring 34 or an
equivalent weight can operate unhindered on the clock work not only during the
remaining part of the period (after the above example 57 seconds), but also during
the short operation of the winding, as during the running down of the spring 34
on the rolling of the planet wheel 31 the ratchet wheel 35 and the bevelled wheel 33
connected therewith act as relatively immovable.
The clock work III can also be operated by the common winding up mechanism
(in the drawing shown by the electro maguet 25). As the contact mechanism and
the winding device is operated periodically by the clock work II as described, of
course a winding or driving device analogous to that described for the clock work. II
could only be applied if the clock work III has always an exactly equal velocity
like the clock work II. But this we have supposed not to be the case; therefore
I have constructed the mechanism so that, with the impulsion of the clock
work III by means of the winding mechanism common with the clock work II the
period of the winding of both works is made dependent only from the movement
of the clock work II, but simultaneously the impulsion of the winding to the clock
work III is effected according to the running down of this clock work III.
Whilst thus the details of the intermediary driving work in the clock work III
agree essentially with the differential arrangement in the clock work II, the effect
of the electro magnet on the driving organ of the clock work III must take place
in an other manner. Instead of a ratchet wheel which for instance in the clock
work II at each period was pushed forwards, cqually for one tooth, there is there-.
fore arranged in the clock work III a bell crank lever the one arm 38 of which is
moved as much forwards by means of dog 40 on the magnet armature rod 37 at
each operation of the electro magnet armature 13, as corresponds to the running
down of the clock work III effected during the corresponding period. This running
down of the clock work III during a revolution period of the clock work II is of
course as different from the running down of the clock work II as the difference
of motion of the two clock works. Herefrom depends also. the position which the
arm 38 takes at the moment of the winding effected by the pin 40. When the
oscillatory organs of the clock work III turn the axle 42 in the known manner by
means of the toothed wheel 41 when the clock work runs down, (which action can
also be effected as in the clock work II under the effect of an intermediary driving
spring 43 by using the differential bevelled wheel transmission or in any similar
manner), an arm or pin 44 on the axle 42 is turned upwards simultaneously with
the angular movement of the axle 42 when the clock work runs down and this arm
lifts an arm 45 which is fixed on the axle 46. The axle 46 and with it an other
arm 47 is also turned and by the saine also the arm 39 is lifted upwards. The
arm 39 is seated on the sleeve 48, on which also the before described arm 38 is
fixed, which is moved forwards periodically by the dog 40 operated by the electro
magnet. armature to a certain position. The sleeve 48 carries besides a ratchet
wheel 49 which during the forward push of the arm 38 is also turned forwards and
moves by means of a coupling represented by the dog 50 also the ratchet wheel 52
forwards, which seated on a sleeve 51 and turnable also round the axle 42 is toothed
inversely. As the ratchet wheel 52, which is prevented from going backwards by
means of the pawl 53, is solidly connected with the bevelled wheel 54 therefore
by means of the described transmission by means of double stopping coupling the
impulsion effected periodically on the arm 38 is further transferred by the bevelled
wheel 54 to the planet wheel 55, and by the upward movement of the latter the
intermediary adjustable driving spring 43 is tensioned as much as it has run down.
It can thus be seen that by the transmission of the turning movement of the
axle 42 when the clock work III runs down, also the arm 38 moves exactly corre-
sponding to the running down and thus in spite of the periodical operations of the
winding organ effected under circumstances in quite different positions of the

page_text: movement of the clock work III the tensioning of the intermediary driving work
of the clock work III can only be effected exactly to compensate for the amount
which the clock work III has run down.
There remains still to be described the manner of operating of the cam 26 (see
Figs. 1 and 5).
This cam is fixed on the axle 1 of the clock-work II and effects the stoppage of
the two clock-works in such a manner when the winding force of the electro-magnet
or the like ceases, for instance when the driving tension ceases, that during the
stationary position, the current-circuit of the winding-electro-magnet is closed
under all circumstances.
For this purpose there is seated on the lever 37 of the electro-magnet armature 13
a pin 56, which, when the armature 13 is operated by the electro-magnet 25, moves
a vertical rod 57 forwards, whilst in consequence of a tension-spring 59 this lever 57
slides with a pin 58 easily on the disk 26 during the time, when the armature is
not attracted. The position of the disk 26 on the axle 1 is made in such a manner,
that during the time, when the contact work is closed, that is, whilst the point 5
of the disengaging lever 4 is still before the projection of the cam disk 2 the recess
in the disk 20 passes exactly under the pin 58 of the disengaging arm 57.
If now at normal working during these moments (for instance 3 seconds) the
electro-magnet 25 is excited in consequence of the closed contact 23-24 and has
attracted the armature 13, the forward movement of the lever 37 presses also the
disengaging lever 57 forwards by the pin 56 and the pin 58 is kept away from the
disengaging disk 26. When however no working-current of the electro magnet 25
passes in spite of the closed contact 23-24, for instance because the conductors aro
interrupted, the armature 13 remains in its stationary position and the pin 58 of
the disengaging lever 57 falls in consequence of the drawing force of the spring 59,
before the point 5 of the lever 4 can fall down the projection of the cam disk 2,
into the recess in the disk 26, so that the clock-work II is stopped. In consequence
of a simple detent which extends from the lever 57 into the swinging parts of the
clock-work III, the latter is also simultaneously stopped.
As at this stopping of the two clock-works the circuit of the electro-magnet
must always be closed by the contact 23-24, therefore the winding device is at once
again put into operation at the moment of the current admission. as the electro
magnet armature 13 is attracted and the rods 14 and 37, and by these in the
described manner after having freed the disk 26 the contact work I and the clock-
works II and III are put into operation.
It may also be mentioned, that the periodical movement of the electro-magnet
armature can also be simultaneously used for working further clock-works,
indicators, or counters without these operations interfering with the working of the
clock-works.
It is evident that also a single clock-work can be operated in an analogous
manner by a convenient application of the herein before described device with
regulatable, constantly operating driving power, and that any partial application
of the one or of the other characteristic organ of the present winding-device for
the mechanical or electric working of one or more clock or going works falls within
the scope of the present invention.

page_text: An Improved Device for Winding up Clocks or Clock-works.
I, PAUL EIBIG, of 16, Annenstrasse, Berlin, in the Empire of Germany, Mechanic,
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 follow-
ing statement:-
My invention relates to a winding up device by which two or several clock works
or similar mechanisms can be wound up simultaneously from a common motor
or mechanism at equal intervals said motor actuating a set of driving arrange-
ments, each of which is capable of adjustment and operates one of the clockworks.
The clock-works can have different velocities and the winding up mechanism can
be operated mechanically as well as electromagnetically. The invention is adapted
for use in connection with electricity meters or other appliances in which the
retardation or acceleration of a clock measured against another uniformly going
clock is employed as a means of measurement.
In the accompanying drawings, in which similar letters denote similar parts,
I have shown a few of the various ways in which my invention may be carried out..
Fig. 1 is a side elevation of an electrical winding device embodying my invention

device.
Fig. 3 is a plan view of Fig. 2.
Figs. 4 to 8 show various details of this construction.
Figs. 9 and 10 are details of a clutch such as used for the partial winding of
the intermediary driving spring of one of the clock works.
Fig. 11 is a front elevation of a third construction of the electrical winding
device.
Fig. 12 is a side view thereof.
Fig. 13 is a plan view thereof with parts in section, and
Fig. 14 is a sectional plan showing a portion of Fig. 13 upon an enlarged scale.
I will now describe specifically the electro-magnetic winding devices whereby
several driving springs which I have called intermediary driving springs or other
motors of the clock-works may be regularly rewound, said winding operation being
controlled by one of the clocks. Thus the whole mechanism will comprise for
instance an electro-magnetic winding device, a clock work of constant speed and a
clock work of variable speed. The winding device may be operated for a few
seconds every minute and may then remain inactive. The clock work II com-
prises principally the driving spring 46 the epicyclic wheel 97 and wheel train 96*
95, 94, 201, 202 leading to an escapement (not shown).
As shown in Figs. 2 to 8, the clock work II which operates at a constant uniform.
speed has an axle 86 carrying a cam disk 87 adapted to impart a swinging motion
to the lever 42, pivoted at 43. This lever has a projection 41 adapted to control
the operation of the contact device which periodically sends the current to the
electro-magnet coils 23:
This contact device consists of a spring 88 the inner end of which is secured to
an axle 33, while its outer end is secured to the casing 34 containing said spring.
The axle 33 also carries the ratchet wheel 32 provided with a pawl 84, upon the
framework, and each time the armature 24 is attracted the said ratchet wheel 32
will be carried forward the distance of one tooth by means of the pin 31, upon a
rod 30, which is connected to the armature 24. This will obviously wind the spiral
spring 88 from its inner end. The uncoiling of the spring 88 is regulated by
the action of the casing 34, which carries a toothed wheel 35 engaging a pinion 36.
Upon the axle of this pinion is fixed a rotary two armed lever 38 carrying two pins

page_text: or projections 39 and 40, at different distances from the axle. These pins 39 and 40
are adapted to engage alternately the projection 41 of the lever 42, so that the
latter arrests the motion of the lever 38 until said lever is released by the move-
ment of the lever 42.
Every time the end 85 of the releasing-lever 42 in sliding upon the cam disk 87
has nearly reached that point of the disk which is furthest away from the axle 80,
the end 41 of the lever 42 takes such a position as to release the pin 39. The
pinion 36 having its independent driving mechanism, namely the spring 88 (or
some equivalent weight), as soon as the lever 38 is released, as above described
the spring 88 turns the pinion 36 with the. lever 38 one-half revolution, the move-
ment being arrested by the engagement of the other pin 40 with the lever 42 (sec
Figs. 2 & 5). The axle 37 of the pinion 36 carries an eccentric 89, which is
adapted to move a frame 90 laterally either towards the right or towards the left,
according to the position of the arm 38. Said frame 90 pivoted at 90" carries a
contact arm 91 having guided movement and adapted to engage the stationary
piece 92. It will therefore been seen that the lever 42 is practically an escape-
ment lever, which allows the wheel 36 to intermittently perforin one-half revolution,
and that during such movement the frame 90 is moved so as to make the contact,
while during the next movement of the wheel 36, the contact will be broken.
Every time the contact is made the armature. 24 is attracted, turning the
wheel 32 by means of the rod 30 and pin 31 as described and thereby winding
the spring SS, which drives the contact mechanism. During the time the contact
is made between the parts 91 and 92 (this time being about three seconds) the
free end 85 of the lever 42 continues to slide on the cam disk 87 until it reaches
a radial notch of the said cam disk. At that time the lever is thrown into said
notch and the opposite end of the lever releases the stop pin 40 allowing the lever 38
to again perform one half revolution as described. During all the time up to the
short period just before the lever 42 engages the notch of the cam disk 87 (which
time may be about 57 seconds) the eccentric disk 89 remains in the position shown
in dotted lines in Fig. 2, that is, the parts 91 and 92 are out of contact and the
electro-magnet 23 is inactive.
"
Since the contact devices are exactly timed by the clock work II, the electrical
winding device herein before described will operate with an alternating current
as well as with a continuous current, the current duration not being momentary,
but lasting an appreciable time, say three seconds as before mentioned.
It will be obvious that the lever 42 of the contact device may be operated directly
from any other part of the clock work II, for instance, the lever 45 of the inter-
mediary driving mechanism may be used for this purpose.
This arrangement is represented in Figs. 8, 1, 11, and 13. The helical spring 46
drives the clock work II, as will be described hereinafter, and is periodically
rowound by the main winding mechanism, namely, the electro-magnet 23. During
the running of the clock the bevel planet wheel 97 (Fig. 1) gradually moves up-
ward (or downward in Fig. 2) and the arm 45 (Fig. 1) connected therewith moves
downward permitting a downward displacement of the lever 42 against the projec-
tion 44 on which the arm 45 rests, the lever 42 as herein before stated being.
rotatably mounted upon the axle 43. The projection 41 moves. upwards and
thus releases the pin 40 on the lever 38 of the contact mechanism. The lever, 38,
as before described performs a half revolution, being arrested by the contact of
the pin 39 with the lever 42, said lever 38 being driven by the spring 88 of the
contact mechanism, which spring drives the lever 38 by means of the toothed.
wheel 35 and pinion 36.
In this position current is supplied to the magnets 23 causing the clock work II
to be rewound; the arm 45 being thus raised again to the position shown in Fig. 1,
lifts the pin 44 of the lever 42 thus lowering the end 41 of said lever permitting
passage to the pin 39 and arresting the pin 40, in which position the parts are
illustrated in Fig. 1, the current being cut off from the magnets 23...
Instead of the shifting frame 90, I may employ a simpler contact device, which

page_text: as illustrated in Figs. 1, 11, and 13 consists of a conducting plate 55, having an
insulating segment 54 and mounted to rotate with the axle 37, said plate being in
contact with a brush or sliding contact 22, secured at 118. The operation of this
modification will be obvious.
It will be necessary now to show the action of the winding mechanism on the
two clock works II and I which we may presume to be running at different
speeds.
The clock work II as above described, actuates the electro-magnetic winding
device at regular intervals, for instance, at every revolution of the axle 86 that is
to say, the winding recurs regularly after the clock work II has run
a certain
length. The axle 86 also carries a notched disk 93, the purpose of which will be
described presently, and a pinion 94 engaging a wheel 95.
The main winding device, that is, the electro-magnetic winding device (or as
its equivalent, a main spring or the like) does not serve as a means for directly
actuating. the clock work II but acts through some intermediary mechanism, such
as differential gearing. The purpose of this arrangement is to avoid irregularities
in the motion of the clock work such as might be caused by the periodical opera-
tion of the winding device, and also to have at ones disposal an intermediary
power (a coiled spring or weight) capable of adjustment according to requirements.
As illustrated in Fig. 3 the oscillating parts of the clock are actuated by a bevel
wheel 96 through the medium of a shaft 47 and gearing 95, 94, 201, 202. The
bevel wheel 97 drives the wheel 96 and rolls upon a bevel wheel 98 and at the
same time it moves downward like a planet wheel round its own axis 45 and about
the axis 47, this motion being small and being accomplished by means of the
intermediary coiled spring 46.
The coiled spring 46, which as will be seen, acts upon the clock work directly,
can be made capable of adjustment so that the desired amplitude of oscillation
of the balance may be obtained, and by means of differential gearing, as described,
this intermediary spring is wound or distended at regular intervals without dis-
turbing the driving of the clock. The periodical. winding or distending is effected
by the armature 24 of the electro-magnet, which armature carries a slightly movable
arm 25 adapted to be moved forward when the armature is attracted and to move
the ratchet wheel 48 by means of its pin 49.
The ratchet wheel 48 is held against rearward movement and is rigidly con-
nected to the bevel wheel 98, but is loose as well as said bevel wheel upon the
axis 47. Instead of operating the ratchet wheel 48 electro-magnetically, I may
employ other actuating mechanism therefor. The bevel wheel 98 drives the planet
wheel 97 and the parts connected therewith, thus, at each operation of the ratchet
wheel 48, the planet wheel 97 will rise (Fig. 2) or fall (Fig. 1) actuating the arm 45
and winding or distending the intermediary spring 46, this winding movement
being always the same. This winding of the intermediary spring is repeated at
intervals, and as shown in the drawings the operation takes place after each com-
plete revolution of the axle 86 of the clock work II. Each time the armature is
attracted the ratchet wheel 48 moves forward by one tooth, and the intermediary
spring 46 (or a weight used as the equivalent thereof) can act upon the clock
work, not only during the time the armature is stationary (57 seconds as in the
example mentioned), but also during the short period (3 seconds) the armature
moves. This is made possible by the arrangement of the planet wheel 97, which
rolls upon the bevel, wheel 98 at the time the armature is attracted, the bevel
wheel 98 and the ratchet wheel 48 rigidly connected therewith remaining rela-
tively stationary during such movement.
t
The clock work I is also driven by the common driving mechanism; that is the
electro-magnet 23, as illustrated. Since the contact device and the winding
device are operated periodically by means of the clock work II, it is obvious that
analogous devices could be employed for the clock work I only in case both clock
works had always exactly the same speed. This invention, however deals with a
construction in which the speed of the two clock works is not always the same.

page_text: The common winding mechanism therefore, must be so constructed as to be con-
trolled by one of the clock works, for instance, the clock work II, but at the same
time the amount of action of the winding device upon the other clock work I must
be dependent upon the amount of unwinding of clock_work I.
The intermediary driving wheel for the clock work I can be made substantially
like that used for clock work II. The connection of the winding magnet with
the clock work I is however, different. In Figs. 2 and 3 I have shown one construc-
tion for this purpose and in Figs. 9 and 10 another arrangement.
In Figs. 2 and 3 I have provided instead of the ratchet wheel used
in the clock work II, an angular piece having an arm 99, which
at each operation of the armature 24 is moved forward by a projection 50 on
the bar 25, the extent of this movement corresponding to the number of revolu-
tions of the clock work I during the same period. It will be obvious that if the
two clock works are not running at the same speed, one of the clock works will
require to be wound more than the other in order that the original tension of
their driving springs 46 and 53 may be restored. For this purpose the arm 99
is arranged to assume a position which depends on the number of revolutions the
clock work I has made since the next preceding winding.
The clock train is driven by a gear wheel 101 which turns with the wheel 200
loose on the axle 1, an intermediary, differential or other gearing being employed
to drive the wheel 200. The axle 1 carries a projecting arm or cam 102, adapted
to lift an arm 103 secured to the axle 104. The axle 104 is thus turned, and
another arm 105 secured to said axle lifts the arm 100 upward. The arm 100
is secured to a sleeve 106 which further carries the above mentioned actuating
arm 99, adapted to be periodically operated by the pin or projection 50 on the
rod 25. The sleeve 106 also carries a ratchet wheel 107, which is turned forward
at each forward movement of the arm 99, and which by means of the pawl 108
turns the ratchet wheel 110 forward, said ratchet wheel having its teeth facing
in the opposite direction and being secured upon a sleeve 109, likewise mounted
to turn on the axle 1. Since the ratchet wheel 110 which is held against rearward
movement by the pawl 111, is rigidly connected with the bevel wheel 112, the
periodical movement imparted to the arm. 99 by the rod 25 is transmitted through
the bevel wheel 112 to the planet wheel 113, and by the upward movement of the
said planet wheel the initial tension of the intermediary driving spring 53 is
restored.
It will therefore be seen that the position of the arm 99 at the time it is operated
by the electro magnet through rod 25 corresponds exactly to the number of revolu-
tions the clock work has made since the last actuation of the said arm. Therefore,
the clock work will be periodically rewound in such a manner as to restore the
original tension of its spring, even though the unwinding of the said spring or
the motion of the clock work, should be irregular between the periodical rewinding
operations.
The periodical rewinding of the clock work I may also be accomplished by a
clutch mechanism such as shown in Figs. 9 and 10. On the axle 1 of the clock
work I is secured a spring casing 128, to which is secured one end of a spring 129,
the inner end of said spring being connected with a sleeve 130. This sleeve passes
loosely through a gear wheel 131 integral with the casing 128. Rigidly upon
the sleeve 130 is secured a gear wheel 132, carrying also part of a clutch 133. A
second sleeve 135 is loosely mounted upon the sleeve 130, and carries a counter
part of a clutch 134, and a driving wheel 136 which may be a ratchet wheel adapted
to be moved forward substantially as described, by cach operation of the winding
electro-magnet; or in case a rotary armature is employed, said armature would
carry a pinion engaging the toothed wheel 136. To prevent rearward movement
I employ a ratchet wheel 137, secured to the sleeve 130 and engaged by a pawl 138.
The gear wheel 131 also carries on its side one or two small wheels 140, mounted
to turn on a pin or pins 139 secured to the wheel 131, said wheel or wheels 140
carrying a wedge-shaped projection or projections 141 adapted to act on the clutch

page_text: through lever 143 engaging an annular recess 145 in the sleeve 135, said lever being
pivoted at 144 on the wheel 131. The operation is as follows:-
The clutch 133 and 134 being in operation, the wheel 136 is moved forward by the
winding mechanism, and the inner end of the spring 129 is wound by means of
the sleeve 130 and then the spring 129 acts upon the clock work I through the
medium of the wheel 131. During such movement, the wheel 140 which turns with
said wheel 131 rolls upon the gear wheel 132 which is held stationary by means
of the ratchet wheel 137 and the pawl 138. During such rolling movement, the
wheel 140 will, of course; rotate about its own axle 139, and if both clock works I, II,
rotate at the same speed the clutch 133, 134 will be operated in the samo way at
the next periodical action of the winding device; that is, the intermediary spring 129
will be wound to the same extent. Should, however the speed of the clock work I
be less than that of the clock work II, the wheel 140 during its rolling motion will,
by its wedge-shaped projection 141 press upon the pin 142 which is secured to a
spring 143 carried on the wheel 131 at 144. The spring 143 lies in a groove 145
and surrounds the sleeve 135, so that when the spring is moved as described; the
sleeve also is shifted and causes the part 134 of the clutch to move out of engagement
with its mate 133, and the next movement of the rod 25 will only idly turn the
sleeve 135. This will also occur with each successive movement of the rod 25
until the projection 141 shall have passed from under the pin 142, and the clutch
shall have come again into engagement.
I have further provided an arrangement whereby the circuit of the winding
magnet will be kept closed if for instance through the switching off of the current the
clock work has not been rewound and has run down. This I accomplish by means
of a disk 93 secured to the axle 86 of the clock work II (see Figs. 2, 3, 6, and 7).
The bar 25 of the armature 24 carries a pin 114 which, when the armature is
attracted, is adapted to move a vertical rod 115 forward, while when the armature
is not attracted, a spring 117 causes a pin 116 secured to the lever 115 to remain
in sliding engagement with the disk 93. Said disk is so secured to the axle 86,
that at the time the contact device is in operation, that is, when the pointed end 85
of the releasing lever 42 is in advance of the step of the cam disk 87, the notch
in the disk 93 will be in exact registry with the pin 116 of the lever 115. When
in normal operation, the electro-magnet 23 is energized by the contact 91, 92, at
the time the lever 115 is in the above described position; the bar 25 in moving for-
ward will cause a like movement of the lever 115, thus removing the pin 116
from contact with the disk 93. Should, however, notwithstanding the contact
made at 91, 92, no current pass through the electro-magnet, for instance, in case
the current is switched off, the armature 24 will remain in its position of rest, and
the pin 116 of the lever 115 will engage the notch of the disk 93 before the end 85
of the releasing lever 42 can move inward at the step of the cam disk 87. Thus,
the clock work. II' will be stopped and at the same time the clock work I will be
arrested, for instance by means of a catch or pawl projecting from the bar 25 and
engaging the moving parts of the clock work I.
It will be seen that when the clock works are arrested in such manner, the contact
is preserved at 91 92, so that in case the current is switched on again, the appar-
atus will be started without delay, the armature 24 being attracted and operating
the winding device, as hereinbefore described, while the stop disk 93 is released..
In Fig. 8 I have shown a modification in which the contact device is actuated
directly from the intermediary driving device of the clock work II as before
described. In this case, also, the construction is arranged to insure a contact at
the time the clock work stops through want of rewinding, so that the mere switch-
ing on of the current will start the operation again. As illustrated, the periodically
rotating winding armature (more fully shown in Figs. 11 to 14 and hereinafter
described) carries a disk 121, provided with a notch 120 adapted to be engaged
by a pin 123 on a lever 122, fulcrumed at 124 and drawn by a spring 125 secured
at 119. The lever 122 carries in its forked upper end a small wheel 126 capable
of a limited turning movement, the movement being limited by a pin adapted to

page_text: engage the fork. When the clock is running at normal speed, this wheel 126 will
approach the gear wheel 127 on the axle 86 of the clock work II only temporarily
during the short winding operation which causes the disk 121 to turn. Should,
however, the current be turned off, or should the current be insufficient to operate
the winding electro-magnet, the wheel 126 will remain in engagement with the
gear wheel 127 and will very soon arrest the clock work, since a few turns will
bring the pin on the wheel 126 against the fork of the lever 122 thus stopping
any further motion. The contact, however, will be preserved as before described
and then the apparatus will operate in the proper manner as soon as the current
is turned on in its full strength. The winding electro-magnet 23 may be used for
actuating at each operation an indicator by means of a click 27 (see Fig. 1) secured
by a spring 26 to the bar 25. The bar 25 is adapted to move forward the ratchet
wheel 19, which is connected with an indicating device of any suitable construction.
Instead of operating the intermediary driving spring, the contact device and
the clock works I, II by a reciprocating armature of the nature illustrated in the
preceding figures, I may employ a rotary oscillating armature, as shown in Fig. 11 to
14. In this case, the electro-magnet 23 is of horse shoe shape and its armature 24 is
of double shape. The armature, as indicated by dotted lines, in Fig. 11, will at
each operation of the contact device perform a partial rotation of about 45° to the
right, and drives the various devices above mentioned by means of toothed gearing,
and as soon as the circuit is broken the rotary armature is brought back to its
oblique, inactive position by means of a spring 28.
On the axle 56 of the armature, is secured a ratchet wheel 57 engaged by a
pawl 58 secured to a disk 59 loose upon the axle 56, so that during the operative
movement of the armature, the said disk 59 will be carried along with the armature,
while during the return movement of the armature the disk 59 will remain
stationary. The disk 59 is connected to gearing 60, 61, 62, 63 by which the move-
ment of the armature is transmitted to the various devices described. Thus, the
gear wheel 63, engages the wheel 64 secured to the spring 88 which drives the con-
tact device. The operation of the contact making parts and of the releasing
mechanism by means of the gearing 35, 36 is the same as berein before described.
The periodical rewinding of the springs of the two clock works is effected, as
will be obvious from Figs. 11 and 13, by the engagement of the toothed wheel 63
with a gear wheel 65 of the clock work II and further by the engagement of the
_ wheels 65, 66, 67 of the clock work I.
The intermediary wheel 66 also operates an indicator or registering device in
the following manner: On the axle 83 of the wheel 66 is secured a ratchet wheel 69
(see Fig. 14) and also a loose double arm 70 carrying two pins 68 and rigidly con-
nected to a toothed wheel 75. The toothed wheel 75 is in permanent engagement
with a wheel 76 connected to the star wheel 6. The star wheel 6 has elastic
connection with the disk 2 by means of the spring 5 pressing the stop pawl 4 into
engagement with the star wheel 6. As shown in Figs. 11 to 13, the disk 2 has
ratchet teeth and is held against rearward movement by the pawl 78 but said disk
moves forward (to the left) with the axle 1 of the clock work I, and consequently
at a speed governed by the speed of the clock work I. At the same time the star
wheel 6 and with it the toothed wheel 76 are moved forward by the elastic engage-
ment of the dog 4 with the star wheel 6. The gear wheel 76 engages a pinion 77
operating the pin 79. This pin or dog is adapted to engage and turn a disk 80
carrying a dial 82, but during the above movement to the left of the star wheel 6 the
pin or dog 79 is moved away from the edge of the disk for an amount corresponding
consequently with the speed of the clock work I.
During the motion of the clock work I the gear 76 75 will cause the double
arm 70 to rotate loosely on the axle S3. Between the bar 70 and the wheel 75
there engages the forked end of the lever 71, fulcrumed at 72. The other arm
of the said lever carries a projection 73 adapted to register with a semi-circular
disk 74. secured to the axle 56 of the armature. When the circuit is broken that
is, the clocks are not being rewound the arm 70 is kept out of engagement with

page_text: the ratchet wheel. 69 by a small spring 84, so that the pins 68 do not engage the
wheel 69. When, however, the electro-magnet 23 attracts the armature. 24,
the segmental disk 74 is turned and engages the projection 73 of the lever 71,
which thus moves the arm 70 towards the ratchet wheel 69 and brings the pins 68
into engagement with the wheel 69. Thus, at the moment the armature is
operated, the wheel 66 is in operative connection with the wheel 75 and turns
it to the left and through this medium the wheel 70, the star wheel 6 and the
other parts mentioned are revolved in the opposite direction to their previous
movement. That is, the star wheel is caused to slip back one tooth under the
dog 4, the dog 79 is moved a uniform distance, and meets and moves the disk 80
which then moves the registering device which consists of an ordinary counting
train, forward a distance which corresponds to the difference in speed between
the clock works I and II during the period since the last preceding winding
operation.
I have fully described my improved device for winding up clock works, but
it is obvious that changes may be readily made without departing from the
spirit of my invention. Furthermore, the relative disposition of the parts may
be altered and the same results secured as by my devices hereinbefore described
and illustrated in the annexed drawing.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is: -
. 1. The combination of two clock works, an intermediate motive power, such
as a spring or weight, for each clock work a winding device operatively connected
to each of said motive powers, and an operative connection from one of the clock
works to periodically actuate the winding device.
2. The combination of two clock works, an intermediate motive power, such
as a spring or weight, for each clock work, a winding device for said motive

one of said clock works, a connection from the winding device to the intermediate
motive power of said actuating clock work to wind said motive power to a con- .
stant amount at each operation, a part connected to move with the other clock,
so that the position of said part will correspond to the amount the intermediate
motive power of, said second clock work has unwound, and an engaging device

the winding device and adapted to so engage the stop disk or an equivalent part
as to keep the circuit closed when the operating current is cut off.

nected to each of said driving devices, a circuit closer controlled by one of the
clock works, and an individual driving device for the circuit closer.
