page_text: 1, PERCIVAL EVERITT, of 47, Cannon Street, in the city of London, Engineer, do
hereby declare the nature of this invention to be as follows:-
-
This invention relies to improved electrical apparatus that is available for use on
the insertion of a coin, token, or the like.
I take any suitable magneto- or dynamo-electric machine that can be actuated by
rotary, reciprocating, oscillating, or other well known mechanical movement by means
of hand power, and I connect one of the handles of the machine to one terminal of the
electric machine. I also connect a suitable stop to this handle so that it cannot be
moved until a coin or the like is inserted in the apparatus to release it. This I effect
by causing the weight of a coin to move a lever which in its turn releases a lever or
stop attached to the handle. Other modifications however can be used.
A second stop is also arranged in connection with the apparatus which stop after
the handle has been turned through a certain number of revolutions will prevent the
further movement of the same until the insertion of another coin.
1 also employ another handle which is connected to the other terminal of the electric
apparatus.
This handle is sometimes arranged so that the strength of the current can he
regulated by suitably moving it and at the same time, if required, the movement
can be utilized to actuate a dial pointer or other indicating apparatus.

page_text: I, PERCIVAL EVERITT, of 47, Cannon Street, in the City of London, 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:-
This invention relates to electrical apparatus that is available for use on the insertion
of a coin, token, or the like, and especially to that class of such apparatus in which a
magneto or dynamo electric machine is employed for the production of the electric
current.
In apparatus of this kind, as heretofore constructed, weight is generally utilized for
producing the necessary motion of the electrical machine, a suitable drop-table being
employed upon which the person using the machine stands.
The object of my invention is to provide apparatus in which the motion of the
electrical machine is produced by hand power, and to this end it comprises the
improvements hereinafter described
In the accompanying drawings
Figure 1 is an elevation (a portion of the external casing being removed) of
apparatus in which the required motion is produced by the rotation of a handle.
Figure 2 is a plan of the same.
Figure 3 is an end view, and
Figure 4 is a view of a detail.
Figure 5 is a view illustrating a modification of my invention.
Similar letters of reference indicate corresponding parts in the several figures.
a is the case in which the electrical machine is enclosed, is a door for affording
access to the interior of such case, and is a glass front through which the mechanism
within the box can be observed.
d is a magneto electric machine having a horse-shoe magnete and the rotating
armature f, such parts being of ordinary construction and mounted in a suitable
frame g.
is a handle by the rotation of which motion is communicated to the armature and
which constitutes one terminal of the machine, the current passing from the coils to
the armaturo shaft and thence through the frame g; and i is a second handle
constituting the other terminal of the machine, the current passing to the same
through the insulated wire, the commutator 3, the brush, and the wire f³.
is a money bucket of well known construction which is adapted to receive the coins
inserted through an aperture in the case, and to discharge the same through the
bottom.
This bucket is mounted upon one end of a balanced lever j✶ mounted on a bracket j¹
projecting from the frame g and provided with an elongated boss, having at its
outer end a short lever carrying a bar j³, at the lower end of which is a plate j*

normally engaging beneath a catch. The catch is pivotted in lugs j' in a wheel /
gearing with a pinion on a shaft, carrying a gear wheel engaging with a
pinion on the armature shaft/'.
The wheel is not keyed to the shaft but is connected thereto by a ratchet and
pawl, the ratchet being secured to the wheel and the pawl to the shaft 12, so
that, when motion is communicated to the shaft 2 in the proper direction, the ratchet
teeth on the wheel will engage with the pawl 18 on the shaft and rotate the
wheel whereby motion will be imparted to the arinature f
m is a gear wheel having its axis in alignment with that of the wheel l. This
wheel m engages with a pinion n on a shaft o one end of which freely rotates within
the pinion, and to which the handle is secured, so that when the said handle / is
rotated, as hereinafter described, the wheel m. will also rotate and thus impart motion
to the wheel and thence to the armature. The said wheel m is provided on its inner
face with a number of lugs or studs p, one of which, during the operation of the
machine is adapted to engage with an arm 7, figure 3, on the catch. While the
money bucket is in its raised position, as shown in figures 1 and 3, the said studs P
are free to pass over the arm as in figure 3, when, however, a coin is dropped into
the bucket, the lever * descends and at the same time the plate and bar are
raised, whereby the catch is also raised thereby bringing the arm into the path of
the studs p so that the two wheels and m will be locked and rotate simultaneously.
r is a cam which is fixed to the frame of the machine and r³, figure 3,
is a hook formed on the arm q and engaging with the said cam. The latter is
for a great portion of its length concentric with the wheel 4, and so arranged that
during the operation of the machine the army will be held in engagement with the
studs p, the remaining portion, however, is curved inwardly, as shown in figure 1,
so that, when the wheel has nearly completed a revolution, the arm q will be drawn
out of engagement with the studs p, whereby the wheels and will be again
disconnected, the bandle being then free to rotate without imparting motion to the
armature.
An opening is formed in the cam so that the arm q is normally disengaged
therefrom, and is thus free to rise when a coin is placed in the bucket, the plate j
being then again raised and with it the catch jo.
An inclined surface on the wheel bears upon the plate as it passes over the
same and depresses it to raise the bucket and discharge the coin.
s is a ::
keeper which is pivotted to the frame g near to the poles of the electro-
magnet and which serves in a well known manner to vary the strength of the shocks
produced by the machine. This keeper is connected by a chain s¹ or its equivalent
passing round a pulley to the shank of the handle i, so that, as the said handle is
pulled outwards, the current will be correspondingly stronger. A spring
to return the keeper to its normal position.
serves
t is a pointer which works in connection with a scale or index u to approximately
indicate the strength of current produced. The said pointer is actuated by means of
an inclined projection u' (figure 4) on the shank of the handle i, the said inclined
projection bearing upon one end of a pivotted lever u², the other end of which is in the
form of a toothed sector 3, the teeth of which engage with a pinion u* on the arbor
of the pointer. A spring returns the lever u² to its normal position.
A pin projecting from a bar el on the frame y enters a slot 2 in the shank of the
handle i and limits the outward motion of the latter, and a pawl engaging with
a ratchet wheel on the shaft o prevents the backward rotation of the handle h.
The operation of the apparatus herein before described is as follows, that is to say,
if a coin is dropped into the bucket, the plate will be lifted by the lever j*, and
move the catch so that the arm q is placed in the path of the studs p whereupon
any motion imparted to the wheel m by the rotation of the handle will be
communicated to the wheel and thence to the other parts of the machine.
soon as the wheel in has made a complete revolution, the arm q is disengaged
from the studs p, so that the handle h is then free to rotate without imparting motion
to the machine.
As

page_text: 1 sometimes modify the construction herein before described, by arranging the
locking mechanism so that the handle cannot be moved until a coin has been
introduced into the apparatus. In this case the bar is arranged to engage with
an arm w on the shaft o to which the handle is connected as shown in figure 5. The
shaft is connected by gearing to the ring a carrying one of the main gear wheels of
the machine, and the inclined surface is connected with this ring and adapted to
act upon the pin y to return the bucket to its normal position. A spring is
provided to act as a cushion to prevent the sudden stoppage of the handle, after it
has been rotated a certain number of times, from damaging the machine.
I wish it understood that I do not limit my invention to the details of construction
hereinbefore described, as it is obvious that the same can be considerably modified
without departing from the nature of my invention. Also, instead of applying my
invention to a rotary machine, it may be adapted to a machine which is actuated by a
reciprocating, oscillating, or other well known mechanical movement.
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
1. A coin-freed electrical apparatus of the kind hereinbefore described, in which
the necessary motion is produced by hand power, substantially in the manner
setforth.
2. In a coin-freed electrical apparatus operated by hand power, the arrangement
of the operating handle in such a manner that it is normally free to move and
only adapted to impart motion to the machine on the insertion of a coin, token,
or the like.
3. In an electrical apparatus operated by hand power, the arrangement of the
operating handle in such a manner that it is normally locked and is only capable of
rotation upon the insertion of a coin, token, or the like.
4. The manufacture and use of coin-freed electrical apparatus operated substantially
in the manner herein before described and illustrated in the accompanying drawings.
