Improved Coin-freed Apparatus for Indicating Speed of Machinery
Worked by the Hands or Feet of an Operator.
I, MONTAGUE STANLEY NAPIER of No. 68 York Road, Lambeth in the
County of Surrey. Engineer do hereby declare the nature of this invention to be as
follows:-
My invention relates to apparatus in which on the introduction of a coin such as
a penny, a spindle or shaft rotated by hand or foot by means of a crank handle is
made to impart its motion to a spindle geared to a speed indicator which shews
visibly the speed of the spindle rotated by hand or foot, while on the reduction of
the speed beyond a certain point, the connection between the crank handle spindle
and that of the speed indicator is automatically broken again.
For this purpose I arrange a weighted lever which is moved on the introduction
of a coin so as to cause an arm thereon to arrest the rotation of a ring shaped frame
that carries a planet bevil wheel gearing with two opposite bevil wheels, one of
which is fixed on the spindle that is rotated by the crank handle, while the other is
fixed on the spindle that drives the indicator on which spindle is also mounted loose
the boss of the said frame of the planet wheel. Thus when the rotation of the said
frame is stopped by the lever, the rotation of the crank handle spindle is trans-
mitted through the three bevil wheels to the indicator spindle and this in actuating
the indicator will cause it to indicate the speed at which the crank handle is revolved.
On the spindle that actuates the indicator is mounted a centrifugal governor, the
sliding sleeve of which is made to travel in one direction or the other as the
governor arms move inwards or outwards according to variations of speed. When
the before mentioned lever is weighted with the coin a rim on the governor sleeve
comes in contact with a trigger lever that holds the coin in a trough on the main
lever, as the sleeve moves backwards and forwards, but when moving in the
direction due to an increase of speed, i.e. when the governor arms are expanding,
the sleeve merely turns a spring joint of the trigger lever, without actuating the
latter. On the speed being reduced again owing to the crank handle being no
longer turned by hand at the required velocity, the governor sleeve in moving back
again, will actuate the trigger lever so as to release the coin on the main lever,
whereupon this will rise and release the planet wheel frame from its arm so that the
turning of the crank handle will then no longer give any indications, until a fresh
coin is introduced:
The indicator employed is by preference a mercurial one, that is to say, one in
which a centrifugal pump forces a column of mercury up a tube, so that the height
of such column indicates the speed. With this form of indicator I combine means
whereby, when a certain very high speed of rotation has been attained by the
person operating the crank handle, he, as a reward, will have his coin returned to
him automatically by the machine. For this purpose, there is provided below the
trough of the lever that receives the coin a shoot leading to an opening in the
casing, so that if the coin falls from the lever to this shoot, it will pass out of
the machine again. The upper end of this shoot is moveable and is mounted on a
pivotted vertical arm, the lower end of which carries a soft iron armature situated
opposite an electro magnet in an electrical circuit, which is ordinarily open. In the
upper part of the tube of the indicator are contacts of this circuit at such a height
that when the mercury column has been raised to that height by a certain maximum
تيم

page_text: speed of the crank handle, it will effect the closing of the electrical circuit, where-
upon the electro magnet being excited will attract the armature and thus move the
arm carrying the upper part of the shoot so as to bring it under the trough of the
main lever, so that when the coin is released from the trough as above described it
will fall into the shoot and be delivered outside the machine again. The upper
part of the shoot has a pivotted side which by means of a projecting arm establishes
a second contact on the electric circuit when the shoot is moved as described, so
that the shoot may be retained a sufficient length of time in the described position
although the contact made by the mercury may only be momentary. On the coin
falling into the mouth of the shoot it moves the hinged side so as to break the
second contact of the circuit again, whereupon the electromagnet will become
inoperative, and the shoot will be moved by a spring into its original position, out
of line with the trough of the lever, in which position a coin falling from the lever
will drop into the machine.

COMPLETE SPECIFICATION.
Improved Coin-freed Apparatus for Indicating Speed of Machinery
Worked by the Hands or Feet of an Operator.
I, MONTAGUE STANLEY NAPIER, of No. 68 York Road, Lambeth, in the
County of Surrey, Engineer, 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 apparatus in which on the introduction of a coin, such as
a penny, a spindle or shaft rotated by hand or foot by means of a crank handle is
made to impart its motion to a spindle geared to a speed indicator which shews
visibly the speed of the spindle rotated by hand or foot, while on the reduction of
the speed beyond a certain point, the connection between the crank handle spindle
and that of the speed indicator is automatically broken again.
I will describe the said apparatus with reference to the accompanying drawings in
which
Fig. 1 shews an elevation of the entire apparatus,
Fig. 2 a section to an enlarged scale through the box containing the mechanism,
shewing an end view of the latter in perspective;
Fig. 3 shews the opposite end view;
Fig. 4 a front view,
Fig. 5 shews a plan, and
Fig. 6 a part longitudinal section.
A is a shoot through which a coin is introduced, and from which it falls into a
bucket c fixed on a lever C pivotted to a bracket C' and having a balance weight C2
which tends to keep the lever and bucket, when empty, in the raised position
shewn at Fig. 4.
When the bucket is in this position, the coin is prevented from falling out of its
open lower end by a pin d, Fig. 2, on an elbow lever D which is pivotted at D' on
the lever C, the one arm of D extending in front of the bucket so that its pin d
enters the bucket through a hole, while the other arm extends back parallel, or
nearly so, with the lever C. When the long end of lever C is thus weighted with
a coin, it descends, and in turning its axis, it brings an aim with a pawl G fixed on
the axis in the path of the tail H' of a cross shaped piece H.
This piece is mounted loose on a spindle L' having its one end supported in a
recess in the spindle L which carries the external crank handle F, while the other
end of spindle L is carried in a bearing L³ fixed to the casing.

page_text: :
The spindle L is carried in a bearing L' fixed to the casing. On the spindle L*
is fixed firstly a worm M and secondly a governor P, the moveable sleeve P¹ of
which is capable of sliding on L while a spring P2 tends to keep it in the extended
position shewn. The spindle L' also has fixed thereon a bevel wheel K, while on
the spindle L is fixed a bevil wheel J, and a bevil planet wheel I carried by the
loose cross piece H, gears with both the wheels J and K. From this arrangement
it will be seen that if the lever C has been depressed by the coin in the bucket c so
that the pawl G projects in the path of the tail H' of the cross shape piece H,
this will be prevented from rotating upon L* together with the planet wheel 1, so
that on rotating the spindle L by means of the crank handle F, the wheel J will
transmit such motion through I to wheel K, and consequently to the spindle L
governor P, and worm M. If on the other hand, owing to the coin being allowed
to drop out of bucket c, the lever C is moved into the raised position by the
counterweight C², so as to remove the pawl G from the tail H', then the piece H
being free to revolve, the rotation of spindle L by the crank handle will only
have the effect of causing the planet wheel I to revolve round wheel K. without
imparting motion thereto and to the spindle LA.
The worm M gears with a pinion N fixed on the spindle O of a speed indicator X,
being preferably a mercurial speed indicator of well known construction that will
indicate the number of revolutions of the crank handle F and spindle L in a given
time. On the lever D is pivotted a trigger d' which, when this lever is made to
descend together with the lever C owing to a coin being in the bucket, is brought
in the path of a flange P³ on the sleeve P of the governor. When, on the rotation
of spindle L', the sleeve P is moved inwards by the expansion of the governor
arms P due to the speed, the trigger d' is merely moved upward on its hinge by
the flange P3, without actuating the lever D, and it drops again after the flange has
passed. When however, on the speed slackening or stopping, the sleeve P¹ moves
outward again, the flange P³ butts against the trigger and in thus pushing
against the one arm of lever D, turns it on its pivot and thereby withdraws the
pin d carried by the other arm from the bucket c, so that the coin therein can
drop out.
The levers C and D then rise again into the position shewn, ready to receive
another coin. The bucket, in rising and falling with the levers, moves in front of
the openings of a shoot T having two passages, the lower one U of which leads to
outside the casing, as shown at Figs. 2 and 4, while the upper one U¹ leads down
to the receptacle at U of the apparatus, and this is so arranged that when the
operator is able to move the crank handle at a certain maximum speed, the bucket
will deliver the coin into the shoot U so that it is returned to the operator as a
reward, while when that speed is not attained, the coin is delivered into the
shoot U¹ This is effected as follows. The mercury column of the speed
indicator X is caused when raised to the height corresponding to the above
mentioned maximum speed, to establish a connection between two contacts on the
electric circuit of a battery Y Y, in which are included electro magnets S S, so
that when the circuit is closed by the mercury column the electromagnets are
excited. Opposite the poles of these magnets is a soft iron armature e¹ on a
lever E pivotted at e, which, when the circuit is not closed, is held by a spring e²
in a position in which a pin c Fig. 2 on lever C, in descending, comes in contact
with the upper end of the lever E, so that the downward motion of the bucket is
topped opposite the shoot U', and the coin is consequently then delivered into
this. When however the circuit is closed as above described, the electromagnets
in attracting the armature e', cause the lever E to move with its end from under
the pin c, and consequently to allow the lever C to descend farther until the pin e¹
comes in contact with the step e on the lever E, whereby the bucket will be
brought opposite the shoot U, and the coin will consequently be delivered through
this, to the outside as described. On the lever E is pivotted a contact lever V,
which, when the lever E is not acted upon by the magnets, has its end situated a
short distance from a contact piece W included in the electric circuit, as shewn at

page_text: Fig. 4, but when the lever E is attracted, the lever V makes contact with W and
thus maintains the circuit closed, although by the sinking of the mercury column
of the indicator the contact may be broken again at the latter, so that the lever E
is maintained in the attracted position for a sufficient length of time to allow the
coin to be delivered into shoot U. The lever V has a tail V' that projects into
the shoot U, so that the coin falling through the latter, in coming in contact with
the tail V, will raise the lever V off the contact W, and the circuit being thus
broken, the lever E will be drawn back into its original position by the spring e.
Although, as above stated I prefer to employ the mercury speed indicator in
combination with my above described invention, yet any other known construction
of speed indicator may be employed in which case any other known device may be
employed for closing electrical contacts on the attainment of the maximum speed,
such as a piece of metal made to travel by centrifugal force against the action of a
spring along a radial arm on a spindle rotated, by the apparatus, the piece of metal
being made to close the contacts on arriving at an extreme outward position, and
being drawn back by the spring on the decrease of the speed.
It will be evident that by connecting the crank handle F by a rod to a treadle,
the apparatus can be worked by the foot instead of the hand.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In coin freed apparatus for indicating the speed of machinery worked by the
hand or foot, the combination of a spindle such as L rotated by the hand or foot,
a spindle such as L, that actuates a speed indicator, and that is geared with
spindle L through a planet wheel motion, and a bucket lever such as C that, when
weighted by a coin, controls the planet wheel motion so as to cause it to transmit
the rotary motion of spindle L to spindle L, while when the lever C is relieved of
the coin it allows the planet wheel motion to be actuated by spindle L without
imparting its motion to spindle L substantially as described.
2. In coin freed apparatus for indicating the speed of machinery worked by the
hand or foot, the combination with a spindle L rotated by the hand or foot, of a
second spindle L₁ that actuates a speed indicator and that is geared with the
spindle L through wheels J K and a planet wheel I carried by a piece H which
revolves freely with the wheel I when the bucket lever C is in the raised position
but which is held stationary so as to cause the motion of spindle I to be transmitted
to spindle L through the planet wheel when the bucket lever is made to descend
by the weight of a coin substantially as described.
3. In apparatus such as is referred to in the preceding claims, the combination
with the spindle L' of a centrifugal governor whose sliding sleeve is caused, on a
certain reduction of speed taking place, to actuate a lever such as D so as to
withdraw a stop from the coin bucket and thus allow the coin to fall out,
substantially as described.
4. In apparatus such as is referred to in the preceding claims, the combination
with the bucket lever C of two shoots, one of which delivers the falling coin into
a receptacle in the machine while the other delivers it out of the apparatus again,
the bucket being made to deliver the coin into the last named shoot by the action
of an electro magnetic controlling device in an electric circuit that is automatically
closed by the speed indicator of the apparatus when a certain maximum speed of
rotation of the spindle L is attained, substantially as described.
5. In combination with the electro magnetic controlling device referred to in
the preceding claim, a contact device such as V V' so arranged in connection with
the electric circuit and with the shoot U as to establish a second contact for
maintaining the circuit closed when the maximum speed is attained, and to be
moved so as to break such contact when the coin is falling through the shoot,
substantially as and for the purposes described.
6. A coin freed apparatus for indicating the speed of machinery worked by the

page_text: hand or foot, combined and operating as herein described with reference to the
accompanying drawings.
