hereby declare the nature of this invention to be as follows:-
My invention relates primarily to mechanism for winding up coin operating
mechanical toys and has for its object to prevent the winding thereof until a coin
lias been introduced into the machine, to prevent the overwinding thereof and to
prevent the rewinding thereof until another coin has been introduced, but my
invention is also applicable for preventing the overwinding of other mechanical
toys or other apparatus.
For this purpose in applying my invention to a coin operating mechanical toy
1 employ a toothed wheel which is provided with an external and internal ring of
teeth and is fixed upon a shaft mounted with, capability of revolution or I might
employ two separate toothed wheels fixed upon the one shaft, and upon the shaft
of this double tootlied wheel fix a ratchet wheel which is at the desired times
acted upon by a driver pressed forward by a spring and this driver is normally
held in its retracted position by a detent which is by suitable means connected with
a lever which projects into the path of the coin passing through the usual money
shoot so that upon the insertion of a coin the detent will be withdrawn and the
driver will consequently through the ratchet wheel turn the double toothed wheel
a given distance.
At a given point a break is formed in the internal teeth of the double toothed
wheel and at a corresponding point a similar but smaller break is formed in the
external teeth thereof and upon the winding shaft which is fitted with a crank
handle or other means of winding is fixed a pinion which in the normal position
of the parts coincides with the break in the external teeth and is capable of freely
turning in either direction without imparting any motion to the double toothed
wheel whilst upon the shaft of the spring or equivalent motor is fixed a pinion
which coincides with the break in the internal ring of teeth.
Upon the introduction into the machine of a coin the spring driver will turn the
double toothed wheel until the external teeth are brought into gear with the pinion
of the winding shaft, when the double toothed wheel may be rotated bringing the
internal teeth into gear with the pinion of the motor shaft and in the continued
motion winding up the spring or other motor until in the revolution of the double
toothed wheel the breaks in the teeth thereof again occupy their normal position
coincident with their respective pinions.
By reason of the break in the internal teeth being larger than that in the external
teeth the internal teeth are disengaged from the pinion of the motor shaft before

Improvements in or connected with Mechanism for Winding up
Coin Operating or other Mechanical Toys or other Apparatus.
I, CORNELIS FREDERIK ALEXANDER RÜELL of The Lyric Club, Leicester
Square in the County of Middlesex, a Jonkheer of the Kingdom of Holland,
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:
My invention relates primarily to mechanism for winding up coin operating
mechanical toys and has for its object to prevent the winding thereof until a coin
has been introduced into the machine, to prevent the overwinding thereof and to
prevent the rewinding thereof until another coin has been introduced, but my
invention is also applicable for preventing the overwinding of other mechanical
toys or other apparatus.
For this purpose in applying my invention to a coin operating mechanical toy
I employ a toothed wheel which is provided with an external and internal ring of
teeth and is fixed upon a shaft mounted with capability of revolution or I might
employ two separate toothed wheels fixed upon the one shaft, and upon the shaft
of this double toothed wheel I fix a ratchet wheel which is at the desired times
acted upon by a driver pressed forward by a spring, and this driver is normally
held in its retracted position by a detent which is by suitable means connected with
a lever which projects into the path of the coin passing through the usual money
shoot, so that upon the insertion of a coin the detent will be withdrawn and the
driver will consequently through the ratchet wheel turn the double toothed wheel
a given distance.
At a given point a break is formed in the internal teeth of the double toothed
wheel and at a corresponding point a similar but smaller break is formed in the
external teeth thereof and upon the winding shaft which is fitted with a crank
handle or other means of winding, is fixed a pinion which in the normal position of
the parts coincides with the break in the external teeth and is capable of freely
turning in either direction without imparting any motion to the double toothed
wheel whilst upon the shaft of the spring or equivalent. motor is fixed a pinion
which coincides with the break in the internal ring of teeth.
Upon the introduction into the machine of a coin, the spring driver will turn the
double toothed wheel until the external teeth are brought into gear with the
pinion of the winding shaft, when the double toothed wheel may be rotated,
bringing the internal teeth into gear with the pinion of the motor shaft and in the
continued motion winding up the spring or other notor, until in the revolution of
the double toothed wheel the breaks in the teeth thereof again occupy their normal
position coincident with their respective pinions.
By reason of the break in the internal teeth being larger than that in the
external teeth, the internal teeth are disengaged from the pinion of the motor shaft
before the pinion of the winding shaft ceases to act upon the external teeth and
thus any danger of the interual teeth remaining in gear with the pinion of the
motor shaft is avoided, whilst a stop is sometimes employed to prevent the double
toothed wheel being carried beyond its precise normal position.
The driver is returned to its normal position in engagement with the detent by
means of a cam or incline upon the double toothed wheel which acts thereon during
the winding up of the motor.

page_text: spensing wICH THE COm operating device aeremverore
described in connection with the driver and adapting the latter to be acted upon
by hand, the mechanism may be adapted to other apparatus or to watches
and clocks.
And in order that the said invention may be more clearly understood, and readily
carried into effect, I will proceed aided by the accompanying drawings more fully
to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front elevation of a coin freed or coin operating winding mechanism
constructed according to my invention.
Figure 2 is an end elevation thereof partly in section.
Figure 3 is a vertical longitudinal section of part thereof and
Figure 4 is a vertical transverse section taken on the line 1-1 of Figure 3.
Figure 5 is an elevation of the pusher and connected parts separately for
throwing the winding mechanism into gear and
Figure 6 represents the application of my invention to a watch.
In the several figures of the drawings, like parts are indicated by similar letters
of reference.
Referring to Figures 1 to 5 a represents the frame of the mechanism and
represents a crank handle by the aid of which the mechanism may be operated.
The crank handle is fixed upon a sleeve b' which is mounted loosely upon a
winding shaft e and is held thereon by means of a pin 61* passing through the
boss of the winding handle 6 and through the sleeve and entering an annular
groove or channel e¹ formed in the shaft c whilst the shaft c is mounted with
capability of revolution in bearings c*.
C
62 represents an arm or offset from the sleeve upon which is mounted a spring
pawl which engages a ratchet wheel e² fixed upon the winding shaft c when the
crank handle is turned in the required direction for winding that is to say to the
right, but slips in the contrary direction so as to prevent the winding shaft c being
turned in the wrong direction.
Upon a short shaft d' mounted with capability of revolution in bearings d¹* is
fixed a double toothed wheel d, and this wheel dis provided with an external ring
of teeth d* and an internal ring of teeth d**, or two separate toothed wheels fixed
upou the shaft d' might be employed in lieu of this compound wheel d and upon the
winding shaft c is fixed a pinion which engages the external teeth * of the
double toothed wheel d whilst the internal teeth ** thereof are engaged by a
pinion fixed upon a shaft e¹ mounted in bearings e¹ and to which shaft ei is
fixed one end of the main spring e which furnishes the motive power to the
mechanical toy.
The main spring e is therefore wound up through the crank handle b, shaft
pinion, external teeth d* of the double toothed wheel d, internal teeth **
thereof, pinion e² and spring shafte whilst the power is given off by the spring e
to the mechanical toy to be set in motion through the shaft e¹ toothed wheel ³
fixed upon the shaft e and pinion to the driving shaft g of the mechanical toy.
The pinion is fixed upon a sleeve which is mounted loosely upon the driving
shaft У which is niounted in bearings g* in the frame a, and the sleeve is formed
with a half clutch which engages a corresponding half clutch f³ mounted with
capability of endway movement upon the shaft g and kept up to its work by a
spring but fixed with the shaft g as regards rotation by means of a screw stud
which engages a groove g' formed in the driving shaft g.
'
.
At a given point a break d**1 is formed in the interual teeth ** of the double
toothed wheel d and at a corresponding point a similar but smaller break dis
formed in the external teeth d. and these breaks ** and d* in the normal
position of the parts coincide respectively with the pinions e* of the spring shaft e
and of the winding shaft c and thus permit the crank handle to be freely

page_text: revolved in either direction without imparting, any motion to the double toothed
.wheel d.
Upon the shaft d of the double toothed wheel dis fixed a ratchet, wheel
which at the desired times is acted upon by a driver pressed forward by a
spring ** so as to bring the external teeth into engagement with the corre-
sponding pinion and this driver his pinjointed at * to the upper end of a
rocking arm which at its lower end is mounted upon an axis of motion !*
carried by the frame a and this rocking arm is provided with a stud 41** which
normally engages a notch /** formed in a detent lever / which holds the driver h
in its retracted position with the spring ** compressed in readiness to act when
released as hereinafter described to give a partial rotation to the ratchet
wheel d².
The detent lever is mounted upon an axis of motion ** also carried by the
frame is pinjointed at * to the lower end of a link or connecting rod 4³ which
at its upper end is pinjointed at ** to a bell crank lever i mounted upon a centre
of motion carried by a bracket a from the frame and the bell crank lever i is
at pinjointed to a link or connecting rod which is at pinjointed to one
arm of a bell crank lever mounted upon a centre of motion: carried by a
bracket * from the back of the money shoot j which latter conducts the coin a into
a suitable money compartment from a money. slot (not shown) arranged in the case
of the machine as is well understood.
The other arm of the bell crank lever is curved and projects into the money
shoot through a slot in the side thereof, as indicated by the full lines in Figure 1
in such a position that a coin of the predetermined kind inserted into the machine
will act thereon and partially turn the bell crank lever upon its axis ** and thus
through the several connections hereinbefore described raise the detent lever
thereby releasing the spring driver and allowing it to give a partial rotation
through the ratchet wheel d to the double toothed wheel whilst the various parts
are counterbalanced by means of a weight **** adjustably mounted upon an arm
or offset 2** of the bell crank lever P.
By these means upon the introduction into the machine of a proper coin the
spring driver (which also acts as a pawl to prevent back action) will be released
by the detent and will spring forward until arrested by the stop *** carried by
the frame a and will thus turn the double toothed wheel & until the external
teeth adjacent to the break d* are brought into gear with the pinion 3 of the
winding shaft c when the double toothed wheel & may be rotated by the crank
handle thus bringing the internal teeth ** into gear with the pinion e² of the
spring shaft e and in the continued rotation of the handle winding up the spring e
until in the revolution of the double toothed wheel d the breaks **** in the
teeth thereof again occupy their normal position coincident with their respective
pinions as indicated more particularly at Figure 4 when the spring shaft
will be free to rotate in the opposite direction and the spring will in the
unwinding thereof give motion through the toothed wheel to the driving
shaft g.
By reason of the break d** in the internal ring of teeth d** being larger than
that d in the external ring of teeth d*, the internal teeth d** are disengaged
from the pinion e² of the spring shaft el before the pinion 3 of the winding shaft c
ceases to act upon the external teeth d*, and thus any danger of the internal
teeth remaining in gear with the pinion e² after the spring e is fully wound up
is avoided.
*
The spring driver is returned to its normal position in engagement with the
notch of the detent lever in readiness for the insertion of another coin inte
the machine by means of a cam or incline d carried by the double toothed wheel (,
and which in the revolution thereof during the winding up of the spring e acts upon
a stud or pin *** upon the arm of the detent lever .
The spring driver when released by the detent meets with some little

page_text: resistance from the double toothed wheel d and it might therefore be possible for
the detent lever after the discharge of the coin from the bell crank lever
to re-engage the stud /** before the spring driver had had time to act, and in
order to avoid this the slot ** of the bell crank lever his formed with a
shoulder **** upon its lower side so that although the detent lever is raised
by the coin a sufficiently to free the spring driver & the detent lever 2 is by means
of the shoulder **** prevented rising sufficiently to allow of the full depression of
the curved arm of the bell crank lever and the consequent discharge therefrom
of the coin until the stud ¹** of the arm ' has been carried forward by the
movement of the spring driver ha sufficient distance to avoid any risk of accidental
re-engagement with the slot 2* of the detent after which the stud *** will act
upon a rise.2****
upon the detent lever and ensure the complete depression of
the curved arm of the bell crank lever and the consequent discharge therefrom
of the coin, should the latter for any reason fail to fully depress the same.
In the example given at Figure 6 I have shown the applicability of the double
toothed wheel to a watch movement in order to prevent the overwinding of the
main spring.
1
In this case the double toothed wheel dis mounted upon an axis of motion d¹
and by its internal teeth d** (which in this example are unbroken) engages a
pinion 2 fixed upon the shafte of the fuzee (not shown) whilst the external teeth d*
engage a bevelled toothed wheel mounted upon a fixed axis and gearing with a
bevelled pinion ** formed upon a sleeve 2*, upon which is also formed a ratchet
wheel which is acted upon by a spring pawl c²*** to prevent back action.
The sleeve is mounted with capability of vertical movement upon a square
formed at the lower part of the stem * of the winder and is engaged by the
forked end of a lever mounted upon an axis of motion * and acted upon by a
spring to normally hold the bevelled wheel 2** out of engagement with the
bevelled wheel whilst a push piece **** is employed to depress the lever h¹ and
throw the wheels 2**, 3 into engagement as represented in the drawings, so that
the double toothed wheel d may be rotated by means of the winder in order to.
wind up the main spring of the watch through the pinion e² and fuzee (not shown)
the parts being so arranged that one revolution of the double toothed wheel d will
wind up the main spring.
By these means, any danger of overwinding the main spring is avoided, as the
double toothed wheel d can only be turned until the break in the external teeth d*
thereof coincides with the bevelled wheel c³.
Having now particularly described and ascertained the nature of my said inven-
ion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a winding mechanism, the combination of a double toothed wheel forned
with a break in one set of teeth, a winding shaft provided with means of rotation,
pinion fixed upon the winding shaft, and corresponding with such break, a break
