A communication from abroad by GEO. K. CHENEY, of 874, Broadway, New York
City, United States of America.
I, WILLIAM LLOYD WISE, of 46, Lincoln's Inn Fields, in the County of
London, Consulting Engineer and Chartered Patent Agent, do hereby declare the
nature of this invention to be as follows;-
My invention relates to coin controlled mechanisms in general, but is more
specifically designed to produce a coin-operated device for throwing into operation
the sound-reproducing apparatus known as the gramophone, and after the opera-
tion thereof, returning the parts to the relative positions necessary for a repetition
of the operation.
The base of an ordinary gramophone supports a box in which is any ordinary
spring or electrical motor for rotating the plate which carries the sound record.
A swinging arm, to which the sound box is attached, carries a horn, all of the usual
and well known construction. A metal casing encloses and protects my coin-
controlled mechanism for operating the gramophone, through the top of which
casing is a coin chute. From the needle carrying arm of the gramophone is a
projection, which engages with the operating mechanism contained in the casing.
The mechanism is set in operation by a push button, through the agency of a
coin introduced through the coin chute, and, mounted in an internally threaded
Jug on the rear end of a pivoted catch, is an.
n. adjusting screw for the tripping
mechanism hereinafter to be described.
When the mechanism is at rest, the brake engages with the rotating plate and
prevents the rotation thereof. A coin being dropped through the coin chute
strikes the coin stop and rests between the coin pushing lever and the coin operated
lever: the operator then pushes on the push button, which forces the coin pushing
lever over against the resistance of the spring and drives the coin forward, and
through its agency pushing forward the coin operated lever. At the same time,
the tripping finger, which is pivoted to the coin pushing lever, and flexibly con-
trolled by the spring, enters behind the locking pin which is mounted on the spring
controlled sliding bolt and arranged at right angles thereto, so that it projects
downwardly into the slot in the bed plate of the apparatus, and normally locks
the coin operated lever.
Such locking bolt being withdrawn by the tripping finger, the coin operated
lever is free to be pushed over by the coin, and after a short amount of travel,
strikes against and begins to move the bell crank. This bell crank has a toẻ
which presses against the yoke, which has a vertical sliding bearing in the box,
in which latter a spiral spring is hidden which normally tends to hold the yoke
in position. On the yoke are journal bearings in which is journalled the return
feed screw.
The projection from the swinging arm of the gramophone rests upon the feed
screw, which when it is in its uppermost position, lifts the needle art of enouge

page_text: ment with the groove in the sound record. The turning of the bell crank forces
the yoke and the feed screw carried thereby, downward, so that the needle is first
lowered into engagement with the groove on the sound record, and then the feed
screw is withdrawn from engagement with the projection. All this is done before
the lost motion or play in the pin and slot connection between the link, pivoted
to the coin-operated lever and the brake, has been taken up. This brake has a
pivoted mounting which bears on the brake with sufficient friction to prevent it
from turning loosely during the taking up of the lost motion in the pin and slot
connection, and after the feed screw has been lowered out of engagement with the
gramophone arm, the link is moved so far that the pin and slot connection has
reached the limit of its play, and the brake is forced to one side out of engagement
with the rotating plate. The gramophone is then free to operate.
At the same time the bell crank lever has been engaged by the spring catch
controlled by the spring. Accordingly on releasing the pressure from the push
button, the spring forces the coin pushing lever back against the stop, and the
coin (having been carried past the coin stop) drops down the passageway into
the money box. The continued rotation of the plate and sound record carried
thereby feeds the swinging arm and sound box over, in the manner familiar to
users of the gramophone.
When the needle has reached the end of the record the adjustable stop has been
so arranged that it will come in contact with the projection from the swinging
arm, and the last few revolutions of the record will suffice to push the spring catch
into position, thereby tripping the same and releasing the bell crank lever. The
spring concealed in the vertical bearing immediately forces up the yoke and return
feed screw, into engagement with the projection from the swinging or movable arm,
and as the belt and pulley on said feed screw cause it to rotate simultaneously
with the rotating plate, the feed screw lifts the needle out of engagement with the
groove in the sound record, and the rotation of the screw slowly swings the arm
back to its original position.
The backward movement of the bell crank also moves the coin operated fever.
which is also a brake lever, inasmuch as it is connected to and operates the brake,
back far enough to take up the play in the pin and slot connection, and bring
the brake nearly into engagement with the rotating plate.
A slight further motion however is necessary to bring said brake into engagement,
and this is supplied by the proiection on the swinging arm coming into contact with
the projecting bolt on the brake lever at the termination of its return motion, and
thereby positively bringing the brake into engagement with the rotating plate
until the motion thereof, and consequently the motion of the return feed screw.
is checked. The machine is then ready for the introduction of another coin and
a repetition of the tune or recitation which has been recorded on the plate.
The lower end of the coin chute is removed at one side and at the back. The
penny is retained in its upright position by the groove in the coin stop. Above
the coin is the knife, which is mounted in a horizontal guide casing. This knife
has a projecting pin, which engages with the slot in the coin pusher or operating
lever, or is otherwise connected to said coin pusher or operating lever, so that the
forward motion thereof will, before the coin has been pushed forward far enough
to drop down the passageway, cause the knife to come over into contact with the
opposite side of the coin chute, and sever any string which the customer may
have tied to the coin in the hope of withdrawing the same after the machine has
been set in operation.
opera-
The foregoing description of the mechanism has also set out the mode of
tion. The advantages of the application of my invention to automatic feeding
machines of the gramophone type, is evident in that a simple and positively acting
mechanism operates at one and the same time to throw the automatic feeding
mechanism into engagement, to withdraw the brake, and permit the same to operate,
and at the end of a predetermined and adjustable cycle of operations, throws the
automatic feeding mechanism out of gear, return the parts to their original

page_text: position ready for a second operation, and then set the brake which holds them
until a second coin has been introduced.
It will be seen that the coin operated or brake lever is also the prime mover
of the train of mechanism for disengaging the return feed mechanism. It is
doubly locked against movement by an inserted wire or other means than an intro-
duced coin, by reason of the fact that not only does the locking pin engage the
notch in the slot, but the spring bolt on which the pin is mounted, is in contact
with the projection of the movable gramophone arm, which has been forced back
against it by the return feed screw.
It is evident of course that various changes could be made in the details of the
mechanism herein described without departing from the spirit and scope of my
invention, so long as the relative arrangement of parts and the principle of opera-
tion set out in the specification, are adhered to. The levers for instance might
be replaced by pieces sliding in straight guides, the various spring catches and
locking bolts and tripping fingers might be of different shape and differently
mounted, so long as they perform the function herein attributed to them.
return feed mechanisms might be substituted for the screw, and other mountings
for such feed mechanisms, which would still allow it to be withdrawn from engage-
ment with the swinging arm during the predetermined period, might be substituted
for that which I have described, but all these I regard as variations in form and
not in substance, and still within the scope of my invention.

A communication from abroad by GEO. K. CHENEY, of 874, Broadway, New York
City, United States of America.
I, WILLIAM LLOYD WISE, of 46, Lincoln's Inn Fields, in the County of
London, Consulting Engineer, and Chartered Patent Agent, 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 coin controlled mechanisms in general, but is more
specifically designed to produce a coin-operated device for throwing into operation
the sound reproducing apparatus known as the gramophone, and after the opera-
tion thereof, returning the parts to the relative positions necessary for a repetition
of the operation.
The preferred form of my apparatus is illustrated in the accompanying four
sheets of drawings, in which,
Fig. 1 is a perspective view of the gramophone with my apparatus attached.
Fig. 2 is a detail plan view of the coin operated mechanism, with the coin in
position ready for operation.
Fig. 3 is a detail elevation of the same.
Fig. 4 is a second plan view of the parts shown in Fig. 2 after the mechanism
has been operated through the agency of the coin, to start the gramophone into
action.
Fig. 5 is an elevation of the same part showing the same position as Fig. 4.
Fig. 6 is a third plan view showing the parts of the mechanism after the coin
has been allowed to drop into the money box, and after the gramophone has

page_text: reached the end of the parucular sound record which it has been arranged to
reproduce.
Fig. 7 is a detail view of the coin chute and coin stop.
Fig. 8 is a section of the same at right angles to that shown in Fig. 7, showing
the knife in position.
Figs. 9, 10 and 11 are details of the knife and knife guide.
Throughout the drawings like reference figures refer to like parts.
1 represents the base of an ordinary gramophone supporting a box, in which
is any ordinary spring or electrical motor for rotating the plate 2, which carries
the sound record 3.
4 represents the swinging arm to which the sound box 5 is attached, and which
carries the horn 6, all of the usual and well known construction.
7 is a metal casing which encloses and protects my coin controlled mechanism
for operating the gramophone, and 8 is a coin chute leading through the top of
said casing.
9 is a projection from the needle carrying arm of the gramophone down into the
casing 7, to engage with the operating mechanism contained therein.
10 is a push button by which the mechanism is set in operation through the
agency of a coin introduced through the coin chute S, and 11 is an adjusting
screw for the tripping mechanism hereinafter to be described, mounted in an inter-
nally threaded lug on the rear end of the pivoted catch 36.
The needle attached to the sound box appears in Figs. 3 and 5, marked 5".
When the mechanism is at rest the operating parts are in the position shown
in Figs. 2 and 3, the brake 34 engaging with the rotating plate 2, and preventing
the rotation thereof. A coin 17 being dropped through the coin chute 8, strikes
the coin stop 40 (see Fig. 7) and rests between the coin pushing lever 12 and
the coin operated lever 16.
At
The operator then pushes on the push button 10 which forces the coin pushing
lever 12, over against the resistance of the spring 13, and drives the coin 17 for-
ward, and through its agency pushing forward the coin operated lever 16.
the same time the tripping finger 20, which is shown pivoted to the coin pushing
lever, and flexibly controlled by the spring 21, enters behind the locking pin 18,
which is mounted on the spring controlled sliding bolt 22, and arranged at right
angles thereto so that it projects downwardly into the slot 19 in the bed plate
of the apparatus, and normally locks the coin operated lever 16 in the position
shown in Fig. 2. The slot 19 is formed of two portions approximately at right
angles one to the other, as shown in Figs. 4 and 6. While the pin 18 remains
in that portion parallel to the sliding bolt 22, no motion of the coin operated
lever 16, is possible. When the bolt 22 is slid along by the trip finger 20 coming
behind the locking pin 18 far enough to bring the pin 18 opposite the other portion
of the slot 19, which is approximately at right angles to the bolt 22, the said slot 19
no longer opposes any resistance to the swinging motion of the coin operated
lever 16. The same action of the locking bolt 22 above described, withdraws its
other end out of engagement with the projection 9 from the swinging arm, and
accordingly this source of opposition to the movement of the coin operated lever 16
is also removed. This engagement of the locking bolt with the projection 9
would under ordinary conditions suffice alone to lock the coin operated lever, but
inasmuch as extraordinary pressure on the push button 10 would shove the pro-
jection 9 along the feed screw 28, the interposition of the slot 19 and locking pin 18
is necessary to produce a positive locking of the coin operated lever against
any force not sufficient to break the mechanism.
Such locking bolt being withdrawn by the finger 20 the coin operated lever 16
is free to be pushed over by the coin, and after a short amount of travel strikes
against and begins to move the bell crank 23. This bell crank 23 has a toe 24,
which presses against the yoke 25, which has a vertical sliding bearing in the
box 26, in which latter a spiral spring is hidden which normally tends to hold the
yoke 25 up in the position shown in Fig. 3. On the yoke 25 are the journal

page_text: bearings 27-27", in which is journalled the return feed screw 28. The yoke
and screw I have shown guided in the vertical guides 29-29".
The projection 9 from the swinging arm 4 of the gramophone, rests upon the
feed screw 28, when it is in its uppermost position, as shown in Fig. 3, and then
lifts the needle 5" out of engagement with the groove in the sound record 3.
The turning of the bell crank 23 forces the yoke 25 and the feed screw 28 carried
thereby, downward, so that the needle 5ª is first lowered into engagement with
the groove on the sound record 3, and then the feed screw 28 is withdrawn from
engagement with the projection 9. All this is done before the lost motion or
play in the pin and slot connection 33, between the link 32 pivoted to the com
operated lever 16 and the brake 34, has been taken up. This brake 34 has a
pivoted mounting at 35, which may consist of the screw engaging a threaded
socket in the base plate, as indicated in Figs. 2 and 6. This screw may be turned
by an ordinary screw driver so as to bear on the brake with sufficient friction to
prevent it from turning loosely during the taking up of the lost motion in the
pin and slot connection, but after the feed screw has been lowered out of engage-
ment with the gramophone arm, the link 32 is moved so far that the pin and
slot connection 33, has reached the limit of its play, and the brake is forced to
one side out of engagement with the rotating plate as shown in Fig. 4.
gramophone is then free to operate.
The
At the same time the bell crank lever 23 has been engaged by the spring catch 36,
pivoted at 37, and controlled by the spring 38. Accordingly on releasing the
pressure from the push button 10, the spring 13 forces the coin pushing lever 12
back against the stop 14, and the coin 17 (having been carried past the coin
stop 40), drops down the passageway 44 into the money box.
The continued rotation of the plate and sound record carried thereby, feeds the
swinging arm and sound box 5, over in the manner familiar to users of the
gramophone.
When the needle has reached the end of the record, the adjustable stop 11 has
been so arranged that it will come in contact with the projection 9 from the swing-
ing arm, and the last few revolutions of the record will suffice to push the spring
catch 36 into the position shown in Fig. 6 thereby tripping the same and releas-
ing the bell crank lever 23. The spring concealed in the vertical bearing 26.
immediately forces up the yoke 25 and return feed screw 28, into engagement
with the projection 9 from the swinging or movable arm, and as the belt 31 and
pulley 30 on said feed screw cause it to rotate simultaneously with the rotating
plate 2, the feed screw lifts the needle 5" out of engagement with the groove in the
sound record, and the rotation of the screw slowly swings the arm 4 back to its
original position.
The backward movement of the bell crank 23, also moves the coin operated
lever 16, which is also a brake lever, inasmuch as it is connected to and operates
the brake, back far enough to take up the play in the pin and slot connection 33,
and bring the brake 34 nearly into engagement with the rotating plate.
A slight further motion however, is necessary to bring said brake into engage-
ment, and this is supplied by the projection 9 on the swinging arm coming into
contact with the projecting bolt 22 on the brake lever at the termination of its
return motion, and thereby positively bringing the brake into engagement with
the rotating plate until the motion thereof, and consequently the motion of the
return feed screw, is checked. The machine is then ready for the introduction
of another coin, and a repetition of the same tune or recitation, which has been
recorded on the plate 3.
The lower end of the coin chute 8 is removed at one side and at the back, as
shown in Fig. 7. The penny is retained in its upright position by the groove 45
in the coin stop 40. Above the coin is the knife 42 which is mounted in a horizon-
tal guide casing 43, shown in Figs. 8, 9 and 10. This knife 42 has a projecting
pin 41, which engages with the slot 39 in the coin pusher or operating lever 12,
or is otherwise connected to said coin pusher or operating lever, so that the forward

page_text: motion thereof, will, before the coin has been pushed forward far enough to drop
down the passage-way 44, cause the knife to come over into contact with the
opposite side of the coin chute, and sever any string, which the customer may have
tied to the coin in the hope of withdrawing the same after the machine has been
set in operation.
The foregoing description of the mechanism has also set out the mode of opera-
tion. The advantages of the application of my invention to automatic feeding
machines of the gramophone type, is evident in that a simple and positively acting
mechanism operates at one and the same time to throw the automatic feeding
mechanism into engagement to withdraw the brake and permit the same to operate
and, at the end of a predetermined and adjustable cycle of operations, throws the
automatic feeding mechanism out of gear, returns the parts to their original position
ready for a second operation, and then sets the brake which holds them until a
second coin has been introduced.
It will be seen that the coin operated or brake lever 16, is also the prime mover
of the train of mechanism for disengaging the return feed mechanism. It is
doubly locked against movement by an inserted wire or other means than an
introduced coin, by reason of the fact that not only does the locking pin 18
engage the notch in the slot 19, but the spring bolt 22, on which the pin is
mounted, is in contact with the projection 9 of the movable gramophone arm,
which has been forced back against it by the return feed screw 28.
It is evident of course that various changes could be made in the details of the
mechanism herein described and illustrated, without departing from the spirit
and scope of my invention, so long as the relative arrangement of parts shown in
the drawings, and the principle of operation set out in the specification, are
adhered to. The levers 12 and 16, for instance, might be replaced by pieces sliding
in straight guides, the various spring catches and locking bolts, and tripping
fingers, might be of different shape and differently mounted, so long as they per-
form the functions herein attributed to them. Other return feed mechanisms might
be substituted for the screw shown, and other mountings for such feed mechanisms
which would still allow it to be withdrawn from engagement with the swinging
arm during the predetermined period, might be substituted for that which I
have illustrated and described, but all these I regard as variations in form and
not in substance, and still within the scope of my invention.
