PROVISIONAL SPECIFICATION.
An Improved Automatic Electric Machine.
I ALFRED HOWARD of 10 Cliffords Inn in the City of London Solicitor do
hereby declare the nature of this invention to be as follows:-
The invention has for its object the supplying of an electric shock in exchange
for a suitable coin.
I provide a box containing in the front of it an opening for the coin to be
dropped through to the inside, two handles, directions, and a dial and small index
finger to register the intensity of the shock.
Inside the box I fix a coin shute, an electric battery, coil, core, regulator and all
the wires and connections required for transmitting the electric current to-the
person holding the handles and also the necessary connecting apparatus for causing
the index finger outside the box to move as the current is being transmitted and
increased.
The left handle is fixed and serves merely to allow the current to run through
the person holding the handles.
The right handle and the mechanism it actuates are connected with one pole
of the battery: the handle has affixed to it (inside the box) a lever, or a toothed
wheel and rack or chain and wheel according to option: the lever rack or chain
(whichever is used) is connected with a coin holder or carrier working in a
longitudinal groove: the carrier has a slot made perpendicularly through it
exceeding the size of the coin only sufficient to enable one at a time to fall
through it (although if desired it may be made wider to take two or more coins
at once): when the carrier is at rest the coin slot in it comes under the bottom
end of the coin shute and receives the dropped coin which is prevented from
passing through by a pin or other suitable piece of metal fixed under the slot:
while the dropped coin is in this position the handle is turned and moves the
carrier pressing the coin against a moveable lever connected with a spring catch
made to fit a notch either in the wheel or the lever; the moveable lever is lifted
or depressed (either movement can be arranged) which pulls the catch out of
the notch and frees the handle: the handle is turned further round, the coin
falls through the slot and the carrier travels along the groove and a contact
maker suitably fixed to it at once touches a piece of wire or metal connected
with one pole of the battery, thereby completes the electric circuit and imparts
a shock to the person holding the handles at the same time the regulator which
is fixed to the carrier is being drawn out of the coil and the shock is intensified.
The degrees of intensity are shown by. figures on the dial outside the box and
when the core is sufficiently uncovered the index finger points to 100 and the
spring catch enters another notch in the wheel or the lever and prevents the
handle from being turned further in the same direction.
:
:
When the handle is released a spring causes it and the mechanical connections to
return to their normal positions: the spring catch re-enters the first named notch
and locks the mechanism: the machine is then ready for the reception of another
coin.

An Improved Automatic Electric Machine.
I ALFRED HOWARD of No. 10 Cliffords Inn in the City of London Solicitor 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 machines for supplying an electric
shock in exchange for a suitable coin.
I provide a wooden box of a size sufficient to hold the mechanism hereafter
described and a suitable battery, induction coil and regulator and necessary
electrical connections: the front of the box which is moveable is hereafter referred
to as the door.
The door has on the outside a coin slot for the coin to be dropped through to the
inside, two handles one for each hand, directions for using machine, a dial with
divisions marked on it numbered 1 to 100, and an index finger moving thereon.
All the interior mechanism is fixed on the inside of the door, and a face view of
it is shown on Figure 1 which is drawn to the size I generally make the same.
Figures 2 to 8 illustrate sections of different parts of the machine also drawn
.to size.
I first fix the right handle with spindle attached to it on the outside of the door :
the spindle projects through the door and I screw on to that end of it which comes
through to the inside of the door the wheel A and fix it by a nut: A is grooved
as shown by a, a, on Figure 2, which is a section of it. I then fasten on by means
of screws the part B, a piece of stout tin, brass plate or other suitable metal bent
as shown in Figure 3: B holds the catch C, which is a piece of steel brass or iron
about of an inch thick an inch long and inch broad (though it and B may bo
larger or smaller as desired) so that C moves in B as shown in Figure 3: Figure 4
is an elevation of B.
I next fix the spring D which serves to press the latch C into a notch a 1 in the
wheel A as shown in Figure 1: I cut away in B the place shown in Figure 4 to
allow the spring D to work in and press C through B into the notch a 1 of A-this
notch is large enough as shown on Figure 1 to give a little play to wheel A.
The next part fixed is the slide E which is screwed flat on to the door in the
direction and place shown on Figure 1: Figure 5 gives a section of E showing the
longitudinal slit or groove e in it, which (see Figure 1) extends from right to left
on the same line as the groove a of the wheel A: one end of the slit e begins with
the third link of the chain and the slit e ends at the extreme right end of the coin
carrier H on Figure 1. The slide has a hollow pillar-F nearly in the middle of
the upper side of it and a solid pin G nearly at one end of the lower side of it, the
exact situations of each being shown on Figure 1: F and G project perpendicularly
about an inch from the face of the door.
I provide to work in the longitudinal slite of E the coin carrier H: Figure 6
is an elevation of H at the side next to L on Figure 1: Figure 5 is the end of H
at the chain on Figure 1. H is made of a piece of brass plate or other suitable
• metal bent to the shape of h1 of the aforesaid Figure 6 with another piece of
brass plate, h 2 of Figure 6 aforesaid, fitted between the sides of h 1 and having a
lip, h4 in Figure 5, and soldered to 1 to form a sloth in Figure 6, sufficient in
.breadth to hold the desired number of coins: the slot h h in Figure 6 is made to
allow two pennies to pass through at once: 3 of Figure 5 is cut in that end only
of, h h to facilitate the passage of coins: the two ends of 1 of Figure 6 are cut as
shown in Figure 5 to allow H to run in the slit e of E-h 1 and h 2 are of the
same breadth which breadth is shown by Figures 5 and 1. 1 connect H to the
wheel A by a metal chain, shown on Figure 1, fixed to h5 of Figures 5 and 6,
the other end of the chain being fastened to the wheel A as shown on Figure 1:

page_text: His chain runs in the groove a 01 A.. At the other end o1 11 1 X the spas
spring K (Figures 1 and 6).
The spring K serves to keep the carrier H close up to the right hand end of
the slit e in E, which is its normal position. The aforesaid chain must be taut so
that one side of the notch a 1 in A is kept close up to the catch C as shown in
Figure 1.
The hollow pillar F is made to hold a pin which is driven into the door: this
pin carries a moveable lever or elbow J made of stiff wire bent as shown in
Figures 7 and 8 into 2 arms j1 and j 2 and soldered on a half inch length of brass.
tube which fits the pin the end of 1 is fixed in line with catch C, is then turned
up into a small hook, and this hook is connected by a piece of wire f1 with C.
The other arm j2 has fixed at the end of it (Figure 8) a piece of brass tube fitting
it closely but moving freely on it; 2 is adjusted so that j3 extends exactly to the
end of the slot h h in H next to it: the adjustment must be further regulated
by making the coins, as they fall into h, touch, but clear j3: to allow the
adjustment2 must be bent as shown on Figure 1.
I fix in the wood at each end of j 2 and 1 stops M and N to prevent the elbow
moving in either direction beyond a certain point: I bend the end of M over j2
by which the elbow is kept on the pin. When j1 is connected with C, and j3, or
the roller end of the other arm rests on the end of the slot of H, all must be so
fitted that there is no play, but so that the least pressure at the roller end of the
elbow instantly acts on C.
The coin shute L is so fixed to the door that it causes the coin dropped through
the coin slot in the front of the door to fall into the slot in the carrier H. When
the coin is so deposited the solid pin G prevents it from falling through the carrier..
As soon as the coin is dropped as last stated the person using the machine turns.
the right handle, which has a small amount of play as before stated given it by the
notch a 1 and as shown in Figure 1, sufficient to allow the coin carrier H carrying
the coin in its slot to be moved against the small roller j 3 of the adjacent elbow
arm and push it up, thereby so acting on the elbow J that it (being connected
with the catch C as before stated) draws the catch out of the notch in and
releases the wheel A-the wheel being released the handle can be turned further
round in the same direction which by a suitable arrangement of wires completes
the electric circuit: the coin falls through the slot of the carrier, and the latter,
being pulled by the chain on the wheel A, travels along the groove of Ẹ.
I fix the coil so that I am able to connect the regulator of it by a piece of stiff
wire to the coin carrier, therefore as the carrier runs along the groove it draws
the regulator with it out of the coil and increases the intensity of the shock.
I cut in the wheel A a second notch a 2 at such a distance from the first named
notch that the catch C enters the second notch as soon as the regulator has
uncovered the core of the coil: when this takes place the handle having performed
its allotted work cannot be turned any further round, and on being released is
pulled by the spring K with the carrier and the accompanying connections to their
normal positions: the catch C then re-enters the notch a 1 in A, locks the
mechanism of the machine and at the same time leaves it ready for the reception of
another coin.
The left handle is fixed and has no part in the above described mechanism as it
is only used to complete the electric circuit in the person using the machine.
Although I have described the mechanism to be used in conjunction with a wheel
and chain, I also claim to use the same apparatus with a toothed wheel and rack
instead of a wheel and chain.
The mechanism can be adapted for any sized coin-the dimensions here stated
and shown on the plates are intended for pennies, and the carrier is constructed to
allow two to pass through it at the same time.
It is not necessary for the purpose of my invention to describe how the electric
current is obtained or applied or the electrical connections or circuits are made or
the dial finger is fixed or connected as I claim nothing in respect thereof.

page_text: Having thus particularly described the nature of my invention and method of
constructing the same and its effects 1 declare the following to be what I claim :
1. The device before described of a holder, spring catch therein, and notch on
the wheel attached to a handle of an automatic electric coin freed machine whereby
the internal mechanism is locked at the handle, and the second notch on the same
wheel whereby the movement of the same handle is arrested at a desired point.
2. The aforesaid method of releasing the catch by means of a coin so held as to
operate on an elbow connected with the catch.
3. The adaptation of the device for any sized coin.
Also the use of a toothed wheel and rack instead of a wheel and chain.
