page_text: Improvements in Coin-freed Mechanism.
I, ELIAS BERNARD KOOPMAN, of 18 and 19, Great Windmill Street, Piccadilly
Circus, London, W., Manager, do hereby declare the nature of this invention to
be as follows:
My invention relates to improvements in coin-freed mechanism which may be
used in apparatus for delivering goods in exchange for coin.
My invention consists in causing the coin to reach by bouncing the position in
which it becomes a link enabling the mechanism to be operated; also in the use of
an inclined and pivotted plate carrying the bouncing block and a slit chute in
which the coin rests, till a crank operated finger swings the plate and forces out
the coin, thereby delivering goods such as post-cards, sweets, cigarettes or the
like in exchange for the coin.
In carrying out my invention according to one modification the penny is inserted
in a slot in the outer case, falls down an inclined chute of suitable length, then
strikes an inclined metal block, from which it bounces into another inclined and
pivotted chute parallel with the first, where it rests. This latter coin chute is slit,
and through the slit a finger passes, the finger being operated by a crank shaft
from outside the case. When a penny is resting in the slit coin chute the next
rotation of the handle causes the finger to engage the penny, and so swings the.
inclined plate or tilting table of which the chute is part, into a nearly vertical
position, and thereby pushes out the goods in exchange for the coin.
With this bouncing arrangement a coin or disc made of zinc or other material
would bounce in a different direction when allowed to fall through the coin chute,
and the space through which an ordinary penny would pass in bouncing into the
second coin chute is so placed that a disc of any other material, such as lead, would
not pass through this space at all, but would be deflected from it, and so would not
free the mechanism.

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
My invention relates to coin freed mechanism which may be used in apparatus
for delivering goods in exchange for coin.
My invention consists in causing the coin to reach by bouncing the position in
which it becomes a link enabling the mechanism to be operated: also in the use of
an inclined and pivotted plate carrying the bouncing block and a slit chute in
which the coin rests, till a crank operated finger swings the plate and forces out
the coin thereby delivering goods such as post cards sweets, cigarettes or the
like in exchange for the coin.
In the
accompanying drawings illustrating my invention applied,
according to one modification, to an apparatus for the delivery of goods in small
packets.
Figure 1 is an elevation of the apparatus showing the mechanism in the lower
part of the case.
Figure 2 is a plan of the coin operated mechanism on the line XX.
Figure 3 is a perspective view of the inclined pivoted plate which carries the
bouncing block.
Referring to the drawings-A is a plate pivoted at its upper end to the sides of
the case and held in an inclined position by the spring B. The lower end of the
plate is pivoted to one end of a pusher lever C which in its turn is pivoted in a
bracket D fixed to the bottom of the case. The upper end of the pusher lever C
carrics a pusher plate E which lies normally upon a projecting ledge E¹ attached
to the bottom support for the goods.
To the plate A is attached a steel bouncing block F on to the edge f (Figure 2)
of which the coin drops from the slit G on the outside of the case. A chute or
space is formed between a vertical projecting piece H and the upturned edge K of
the plate. The distance between H and the block F is so adjusted that only a
suitable coin will bounce from the block I over the upper end h of the projection
into the chute. A lead coin, for instance, would fall short of H into the bottom of
the apparatus.
The coin lies in the chute, covering the slot L (Figures 2 and 3) in the inclined
plate A. It is prevented from sliding off the plate by the guide pieces M, M, which
are fixed to the bottom of the case. On turning the crank handle N the finger R
is rotated and engages with the coin thereby swinging the plate, and operating
the pusher lever C which forces out the goods into the delivery chute P (Figure 1).
As the rotation of the finger continues the coin falls off the plate into the bottom
of the apparatus, the spring B returning the plate to its original inclined position.
The pusher is then in position to force out another package when a coin has been
inserted. When no coin lies on the plate A if the handle N is rotated the finger R
merely passes through the slot L and does not operate the mechanism.
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.—In apparatus for delivery of goods in exchange for coin, causing the coin
to reach by bouncing, the position in which it becomes a link for operating the
delivery mechanism, substantially as described.
2. In apparatus for delivery of goods in exchange for coin, causing the coin
to bounce from a block of suitable material into a slit chute on a pivoted plate
where it lies in position to form a connection whereby the plate may be swung by
a rotating finger and caused to operate delivery mechanism, substantially as
described.
3. In apparatus for delivery of goods in exchange for coin, the inclined pivoted
plate provided with bouncing block, projecting piece, such as II, and slit chute,
substantially as and for the purposes described.

Improvements in Apparatus for Exhibiting a Succession of Pictures,
giving them an Appearance of Motion, and Coin-freed Mechanism
therefor.
I, ELIAS BERNARD KOOPMAN, Manager, of 18 & 19, Great Windmill Street,
Piccadilly Circus, London, W., do hereby declare the nature of this invention
to be as follows:-
My invention relates to improvements in mechanism for exhibiting a series of
pictures in rapid succession, so as to give them the appearance of motion and also
to improvements in coin-freed mechanism which may be used therefor.
One part of my invention consists in an improved method of causing the coin
to reach, by bouncing, the position in which it becomes a link enabling the
mechanism to be operated; also in the use of an inclined and pivotted plate carry-
ing the bouncing block, and a slit chute in which the coin rests till a crank
operated finger swings the plate and forces out the coin, thereby setting free the
picture exhibiting mechanism.
Another part of my invention consists in providing a flexible driving shaft,
and a frictional grooved wheel for causing the worm on this flexible part to be
brought into and out of gear with the worm wheel as required.
The penny is inserted in a slot in the outer case, falls down an inclined chute of
suitable length, then strikes an inclined metal block, from which it bounces into
another inclined and pivoted chute parallel with the first, where it rests. This latter
coin chute is slit, and through the slit a finger passes, the finger being operated
by a crank shaft from outside the case. When a penny is resting in the slit coin
chute, the next rotation of the handle causes the finger to engage the
80 swings the inclined plate or tilting table, of which the chute is part, into a
penny, and
nearly vertical position. A pin on the rear end of this hinged plate pushes forward
a rod against the force of a spring, and causes the returned end of this rod to ride
on an edge cam formed on the side of a worm wheel. The shaft of the worm
wheel carries the drum to which the pictures are attached. With this bouncing
arrangement a coin or disc made of zinc or other material would bounce in a
different direction when allowed to fall through the coin chute, and the space
through which an ordinary penny would pass in bouncing into the second coin
chute is so placed that a disc of any other material, such as lead, would not pass
through this space at all, but would be deflected from it, and so would not free
the mechanism.
The shaft carrying the outside' handle for operating the mechanism has a pinion
on it which gears with a bevil wheel carrying a pin which operates the finger
lever. The other end of this crank shaft carries a worm which gears with the
worm wheel supporting the picture drum. The part of the shaft carrying the
worm is flexibly connected to the front part, so that the worm may be caused to
pass downwards out of gear with the worm wheel. The worm shaft is continued
beyond the worm, and on this continuation is provided a friction gear. This con-
.

page_text: sists of a grooved wheel of suitable material, which rests on the shaft between two
metal flanges. One of these is fixed rigidly to the shaft; the other rotates with
the shaft, but is pressed longitudinally by a spring against the other side of the
grooved wheel. At two diametrically opposite points in the groove of this grooved
wheel, pins are provided, to which links are attached. One of these links is
pivoted at its other end to the framing of the mechanism. The other link passes
up and is attached to one arm of a bell crank lever. The other arm of the bell
crank lever lies in such a position that a pin on the rod which is supported by
the edge cam on the worm wheel will engage with it when the end of the rod passes
off the edge cam by the rotation of the worm wheel. When the bell crank is
operated by the pin, it pushes downward one of the links attached to the grooved
wheel and thereby pushes the worm out of gear with the worm wheel. The
mechanism will not operate again by the turning of the handle until another
penny has been inserted. This acts as before, and causes the rod to ride on the
edge cam, and withdraws the pin from engagement with the bell crank lever.
When the handle is now turned, the friction of the grooved wheel against its
embracing discs causes the grooved wheel to be turned round by the turning of the
handle, and to be thereby lifted on the fixed link as fulcrum till the worm gears
with the worm wheel again. If the crank shaft be turned backwards the worm
immediately passes out of gear with the worm wheel.
According to another part of my invention, I provide means for switching on an
electric lamp to illuminate the pictures when the mechanism is operated, and
which switches out the electric light as soon as the pictures have been shown.
In carrying this part of my invention into effect according to one modification, I
provide a pivoted plate with a suitably shaped edge for releasing the pictures one
by one as the picture is turned past it. The pivot carrying this plate is electrically
connected to one terminal of a lamp, which is placed in a position to illuminate the
pictures. A rod carried by this plate is placed in such a position that as the
pictures are turned round, and this plate turned on its own pivot, the rod project-
ing from the plate comes in contact with a spring metal piece attached to the other
terminal of the lamp. The metal releasing piece thus forms a switch, which
switches on the light when the picture drum is turned, and as soon as the picture
drum is released, this spring plate is by the action of the picture cards, made to
take a nearly vertical position, in which the electrical circuit is broken.
Dated this 7th day of April 1898.

Improvements in Apparatus for Exhibiting a Succession of Pictures,
giving them an Appearance of Motion, and Coin-freed Mechanism
therefor.
I, ELIAS BERNARD KOOPMAN, Manager, of 18 & 19, Great Windmill Street,
Piccadilly Circus, London, W., 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 to improvements in mechanism for exhibiting a series of
pictures in rapid succession so as to give them the appearance of motion and also
to improvements in coin-freed mechanism which may be used therefor.

page_text: One part of my invention consists in an improved method of causing the coins
to reach by bouncing, the position in which it becomes a link enabling the
mechanism to be operated, also in the use of an inclined and pivoted plate carry-
ing the bouncing block and a slit chute in which the coin rests until a crank
operated finger swings the plate and forces out the coin, thereby setting free the
picture exhibiting mechanism.
Another part of my invention consists in providing a flexible driving shaft, and
a frictional grooved wheel which causes a worm upon the flexible part to be brought
into and out of gear with a worm wheel upon the picture drum shaft, as required.
Another part of my invention consists in providing means for switching on an
electric lamp to illuminate the pictures when the mechanism is operated, and
which switches out the electric light as soon as the pictures have been shown.

Figure 14 is a plan of the hinged stop for detaining and releasing the picture
cards.
Referring to Figures 1-5 which illustrate the method of carrying the first
part of our invention into effect according to one modification, A¹ is a coin slit
formed on the outside of the enclosing case A. The penny or other suitable coin
is inserted into this slit and falls down a fixed inclined chute A2, then strikes an
inclined metal block 13 fixed to the plate B (Figures 1 and 2). This plate is
hinged upon the stud A³ fixed to the frame-work, and it is normally held in an
inclined position by the pressure of the spring E¹ against the upwardly projecting
the block B
arm B36 attached to it. The penny bounces from
over
the upper edge of the division ridge B2 into the coin chute B3 which is formed
upon the plate B parallel with the fixed chute A2. The lower end of the chute B³
is provided with a slit B which is covered by the penny when it rests in the position
upon the chute in which it becomes a link enabling the picture exhibiting mech-
anism to be operated. A guide block D (Figures 3 and 5), attached to the knee
plate D2 which is fixed to the side of the case A so that the block D lies parallel
with the chute B³, is provided to guide the penny into its position on the chute.
The projecting pieces D¹ prevent the penny from falling off the chute B³ when it
is in its inclined position. The plate D2 and block D are slit at D' to permit
the finger 15, carried by the pivoted lever J (Figure 1) to pass through and engage
with the penny lying upon the chute B³. The lever J is operated by the rotation
of the shaft C in a manner to be hereinafter described. The finger B5 engaging
with the penny swings the plate B with its chute B³ into a nearly vertical position
and by the pressure against the spring E¹, of the upwardly projecting arm B6

page_text: which is attached to the plate B, causes the rod E to be removed from a locking
notch on the side of the wheel (shown at F in Figure 6) driving the picture drum H
and thus permits the turning of the picture drum by the mechanism hereinafter
described.
With the bouncing arrangement above described a coin or disc made of lead or
other such material would bounce in a different direction from the penny when
allowed to fall through the coin chute A2. The ridge B2 (Figure 2) over the
upper edge of which an ordinary penny would pass in bounding into the coin
chute B3 is so placed that a disc of other material such as lead would not pass
over it, but would be deflected thereby and fall into the bottom of the case A.
Thus the mechanism for rotating the picture drum could not be operated, as the
finger B would then be free to pass through the slit B in the coin chute B³.
This bouncing arrangement also makes it impossible to insert anything such
as wire or metal strip down the slit A¹ to reach such a position as would enable
the mechanism to be operated.
The
The
Referring to Figures 6-13 which illustrate the mechanism by means of which
the rotation of the picture drum is effected, the shaft, C, carrying the outside
crank handle C¹, is provided with a pinion C which gears with the bevel wheel I.
The wheel I operates the finger lever J above referred to by means of the crank-
pin I. The shaft C is provided with a "Hooke's" or other suitable joint C³ and
with a flexible spring shaft C connecting it with the shaft C. The shaft C³ is
supported near its end in a vertically slotted bearing C attached to the frame-
work. The worm K, formed upon the end of the sleeve K', and adapted to gear
with the wheel F, is driven from the shaft C by the pin K2. The sleeve K'
revolves inside of an outer sleeve K" at one end of which is provided a block K*
into which are fixed the short shaft C and one end of the spring shaft C.
"Hooke's" joint C³ is provided to allow the shaft C5 to move vertically so as to
bring the worm k into and out of gear with the worm wheel F. The shaft C³
extends beyond the bearing C and carries a friction gear which consists of a
grooved wheel L, of suitable material, placed between two metal flanges L' and L²,
the flange L' being fixed rigidly upon the shaft, while the flange L² is loose and
pressed longitudinally against the side of the grooved wheel by a spring L³.
wheel groove is provided at two diametrically opposite points with the pins L
and L to which the links L and L' are fixed, as shown at Figures 6, 7, and 13.
One of these links L is pivoted at its other end to the framework at L8 while the
other, L', is attached to one arm of the bell crank lever Lº pivoted at L10. It
will thus be seen that if the handle C is turned the wheel L pressed by the
spring L between the flanges L' and L2 will by its rotation tend to cause the
bell crank lever to rise and bring the worm K into gear with the wheel F. When
no coin has been inserted into the apparatus the wheel F is locked by the inturned
end E2 of the rod E which projects into the locking notch F2 (Figures 9-12).
The pin then prevents the bell crank lever L' from rising and the friction
wheel L cannot operate so as to bring the worm K into gear. Upon the inner
side of the wheel 1 is formed a stepped edge cam F¹ (Figures 9-12) upon which
the inturned edge E2 of the rod E is adapted to ride when the mechanism is
operated. The cam is. cut away at F3 so as to cause the end of the rod E to fall
on to the lower step of the cam as the wheel revolves. When the
revolution of the wheel is complete the end of the rod E falls by way of the
notch into the locking notch F2. The torsion spring E upon the rod E is
provided to turn the end E2 on to the top step of the cam when it is pushed out
of the locking notch F2 by the arm 136 on the motion of the hinged plate B.
The picture drum H carrying the pictures H¹ is mounted on a sleeve H2 which is
slipped over the spindle G fixed upon the outside of the wheel F. The drum is
caused to revolve by the pin G¹ which engages with the projecting piece G2 formed
upon the outside of the wheel F.
The mechanism for detaining and releasing the pictures H¹ one by one and for

page_text: switching on an electric lamp to illuminate the pictures when a coin has been
inserted into the apparatus and the handle C is turned (see Figures 1, 6, 7, and 14)
consists of a pivoted plate with a suitably shaped edge M¹ for detaining or
releasing the pictures one by one as the picture drum is revolved, thus producing
the appearance of motion to the eye of the observer. The pictures are observed
through the hood R, Figure 1. The pivot M2 carrying this plate is electrically
connected to one terminal of an electric lamp N (Figure 1) which is placed in a
position to illuminate the pictures. A rod O carried by the plate M is placed in
such a position that as the pictures are turned round, and the plate M turned on
its pivot M the rod O projecting from the plate comes in contact with an
insulated spring metal piece P attached to the other terminal of the lamp. A
battery or other source of electricity is also in the circuit so that the rod O and
spring piece P form the closing switch of the circuit. The metal picture releasing
piece M thus forms a switch, which switches on the light when the picture drum
is turned, and as soon as the picture drum is stopped this spring plate is by the
action of the picture cards, made to take a nearly vertical position, when the
electrical circuit is broken (as shown in Figure 6). The spring M³ may be used
to keep the rod O out of contact with the plate P when the pictures are not being
exhibited. Figure 1 shows the plate M in action releasing the cards as they
are turned past it.
The mode of operation of the above described mechanism is as follows:-
A penny inserted in the slit A1 (Figure 1) falls down the inclined chute A2 and
bounces from the block B¹ into the chute B3 where it lies, retained by the fingers D¹
in a position covering the slit 14 as shown in Figures 2, 3, and 6. "The handle C¹
is turned, and the wheel I, by its rotation, operates the lever J through the pin I¹
and causes the finger B5 to engage the penny lying in the chute B3 of the plate B,
thereby swinging said plate into a nearly vertical position. When the finger B5
moves sufficiently it causes the penny to fall out of the coin chute into a recep-
tacle below. The upwardly projecting arm 136 pushes forward the rod E against
the force of the spring E' and causes the inturned end E2 to be withdrawn from
the locking notch F2 upon the wheel F. The torsion spring E4 turns the end E²
of the rod E on to the top step of the cam F1 and thus the picture drum is free
to turn. As the shaft C rotates the friction of the grooved wheel between its em-
bracing discs L1 and L2 causes it to turn round on the fixed link L as fulcrum so
as to lift the worm K into gear with the wheel F. If the crank shaft C be turned
backwards the worm K immediately passes out of gear with the worm wheel F.
-The picture drum is thus caused to turn and the plate M comes into operation
detaining and releasing the pictures one by one and at the same time the lamp N,
by the tilting of the plate M, is switched in so as to illuminate the pictures H¹.
The series of pictures are thus exhibited so as to give them the appearance of
motion when observed through the hood R. When a complete revolution of the
drum has been effected the end E2 of the rod E falls by way of the notch F4 into
the locking notch F2 and the pin E³ at the same time causes the bell crank
lever L to lower the worm K out of gear with the wheel F. The picture drum
is then stopped and. the plate M is, by the action of the cards, caused to assume
a position nearly vertical, thus breaking the electric circuit and switching out
the light. The mechanism cannot again be operated until another coin has been
inserted into the apparatus.
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. Exhibiting a succession of pictures giving the appearance of motion by means
of a coin which reaches by bouncing a position in which it becomes a link enabling
the mechanism to be operated substantially as described.
2. In mechanism for exhibiting a succession of pictures giving the appear-
ance of motion, a flexible driving shaft, and grooved wheel such as L with its

page_text: friction plates adapted to operate a picture reel acting substantially as and for

as B operated through a coin by a lever such as J, with a rod such as E, sub-
stantially as described.
4. The combination in picture exhibiting mechanism of a hinged plate such
as B operated through a coin by a lever such as J with a rod such as E and
friction device such as L lifting the gear wheel into mesh with the picture reel
driving wheel, substantially as described.
5. In mechanism for exhibiting a succession of pictures, a hinged stop such
as M acting also as a closing switch establishing the electric circuit of a lamp
illuminating the pictures, substantially as described.
