I THOMAS WILLIAM FORD of Ash Villa Oxford Road Clewer in the County of
Berkshire Electrician do hereby declare the nature of this invention to be as
follows:-
A Box or Case containing mechanism and cells necessary to work the same, of
ornamental design & of suitable dimensions for attaching to a counter or pedestal or
for fastening to a wall, &c.
On the front of the Box or Machine are two pillars or columns of brass or other
metal, one at each side supporting the top. These vertical pillars have on the upper
parts, collars which slide the whole or part of the entire length. Attached to one of
these collars and inside the pillar is a movable primary coil having a hole in its
centre through which passes a soft iron core. The lower portion of this vertical
core is of brass and the upper end extends over the top into the interior of the
box or machine and is fitted with an ordinary Induction coil, containing primary
and secondary layers wound in a contrary direction to the before-mentioned movable
primary, which is attached to the collar.
The effect of this opposite winding is that the magnetism is neutralized when
both coils are on the core but as the movable primary is being lowered from the
iron core on to the brass rod, so the magnetism in the core increases, and the
current in the Induction coil becomes stronger in inverse ratio to the amount of iron
core left in the movable primary. A slot is provided in the front of the machine
for the reception of money, having below it an ordinary lock, the bolt of which
when shot up prevents the insertion of a coin, thus shutting up the slot when the
machine is out of order. Electric action is set up by a penny falling down the shoot
on to a short lever.
An ordinary form of contact breaker is employed in connection with the coil.
The degree of strength of Electric current taken by a person holding the collars one
in each hand and drawing them downwards is registered on a scale engraved or
otherwise marked on the front of the pillars.
The left hand collar may be used when found necessary for switching in extra
cells of the battery thereby increasing the force of the current administered.

page_text: I THOMAS WILLIAM FORD of Ash Villa, Oxford Road, Clewer, Berkshire, Electrician,
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:-
The device or appliance according to my Invention which, in its initial form,
relates to coin freed electrical apparatus, comprises an enclosing case or box for
containing the mechanism and a number of cells to form a voltaic or galvanic battery.
Said enclosing case, which may be of ornamental design, is made of any convenient
size and material suitable for attachment to a counter, pedestal, bracket, wall or the
like, and is provided with two vertical pillars or columns disposed one upon each side
of the front of the enclosing case to support the roof or top thereof. Within one of
the pillars or columns aforesaid is arranged the induction coil, and within the
enclosing case above mentioned is disposed a contact breaker and the locking and
releasing mechanism.
Referring to the accompanying drawings which form part of my Specification
Figure 1 represents a front elevational view of the improved apparatus according to
my Invention; Figure 2 is a sectional elevational view of a portion of one of the
columns above referred to; Figure 3 is a plan of a switch for the purposes to be herein-
after more particularly referred to, and Figure 4 is an elevational view of the
locking and releasing mechanism.
Upon one of the vertical pillars or columns A supporting the roof or top of the
enclosing case and which serve as electrodes for conducting the electric current,
I provide a sleeve or collar B of suitable length, free to slide upon said pillar or
column, but which is maintained in the normal position-preferably at the top thereof,-
by the tension of a spiral spring or its equivalent arranged within the column A.
Within the upper part of the column A is fixed a coil U, consisting of a bobbin of
suitable dimensions, upon which is wound two helices of wire, serving as the primary
and secondary coils. Upon the upper surface of a block plate or equivalent D, which
is secured to the sleeve or collar B. Figure 2, by a screw or other suitable fastening,
passing through a longitudinal slot in the column A, rests a rod E of brass or other
non-magnetic metal or material, upon the upper extremity of which is secured, by any
convenient means, a rod F of soft iron serving as a core for varying the intensity of
the electric current.
Now upon drawing down the sleeve or collar B upon the column A, the soft iron
core will be caused to pass into the coil C, the variation of the intensity of the
current being in proportion to the distance the core is caused to descend into the
bobbin.
Instead of arranging the coil or coils C within the upper part of the pillar or
column A, I may fix said coil or coils in any other convenient position, and dispose

page_text: the sleeve or collar B at the base of said pillar or column, from which it may be
raised, causing the core to enter the bobbin from below instead of from above as
before described; said sleeve or collar and core falling by its own gravity to the
normal position, under which arrangement I am enabled to dispense with the spiral
spring or equivalent above referred to.
As a modification to the foregoing, I may fix in or over the right hand column two
coils of wire, the top coil being wound in a contrary direction to the lower coil, which
latter is fixed to the base block D of the collar above described, and is lowered off the
core which passes through both coils by the descent of the collar, upon the catch being
released by the weight of a coin. In this arrangement the electric currents passing
through the two coils would be neutralising each other, the effects whereof would be
rendering scarcely perceptible to the person holding the electrodes, the variation of
the intensity of the current depending upon the distance the core is allowed to extend
into the movable coil in its vertical motion.
I may also employ a loose primary coil sliding within a secondary coil upon
a fixed core, or any other well known means of varying the intensity of the
current.
To the under surface of the block or plate D Figure 2, is secured a rod or tube G
terminating at its lower end in a block or plate H Figure 4 upon which latter is
pivoted a balanced lever K, having a hook like catch or pawl J formed 'thereon, which,
when the sleeve or collar B is at its highest position, engages with a similar catch or
pawl M rigidly attached to a supporting plate within the enclosing case or box. The
shorter arm N of the lever K may if desired be provided with a movable counter-
weight to allow of the proper adjustment of the catch relative to the weight of the
longer arm of the lever K, the extremity of said longer arm being so disposed as to
be suspended beneath, and covering the lower aperture of a shoot or channel, down
which a coin, token or the like falls, when inserted into a slot formed for the purpose
in the front or any other suitable part of the enclosing case or box.
Within the enclosing case or box aforesaid, are arranged a number of cells, so set
up or connected as to form two voltaic or galvanic batteries; the object of thi=
arrangement being not only to ensure greater efficiency and economy in the application
of the current generated, but also to allow of the current being augmented as may be
desired. This is effected by the interposition in the electrical circuit of a switch O
Figure 3 of any suitable type, which, secured to the interior of the enclosing case, is
manipulated from the exterior thereof by the person using the apparatus, by means of
a knob, milled head, or wing nut P secured to a spindle passing through said
enclosing case, whereby one portion of the battery only may be employed, or, if
a more powerful current is desired, the whole of the battery may be switched into
the circuit.
Instead of the switch above described, I may utilize a collar upon the left hand
pillar or column to actuate a switch disposed in any suitable position, by moving
which to the left or right, or vertically as may be desired to effect the necessary
change in the battery power.
A contact breaker of any desired type is also included in the electric circuit in
order to render the current intermittent.
When a coin, token or the like of predetermined weight and value is inserted in
the slot a formed as above described in the enclosing case, it falls by its own gravity
upon the end of the balanced lever K which is depressed thereby and the catch or
pawl J is disengaged from the hook M, the sleeve or collar B. being free, may now
be drawn down. In its descont a pin or projection secured to or formed upon the
block H, makes a rubbing or frictional contact with a spring or equivalent, thus
closing the electrical circuit and allowing the current to flow, the variation of the
intensity of the current being, as herein before described, determined by the distance
the core enters the coil; such variation in the intensity of the current being
approximately indicated by means of a graduated scale formed upon the surface of the
pillar or column A, as shown in Figure 1, and which graduated scale is disclosed
to view as the sleeve or collar B is caused to descend.

page_text: In order to prevent the insertion of coins, tokens or the like into the slot a, and thus
lock the apparatus against further use, I adapt to the interior of the case a lock, the
bolt of which, when shot, covers or partially covers the slot a aforesaid, thus effectually
preventing the insertion of any substance therein until the bolt has been withdrawn
by the proper key.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I wish it to be under-
stood that I am aware of the existence of machines for the administration of a current
of electricity to persons holding, rotating, pushing in or pulling out handles or knobs
in a horizontal direction, and I do not in any way claim the herein mentioned or any
other known means of varying such current, either in a coin freed or automatic
machine, or in an Electro Medical battery or apparatus having no such coin freeing or
coin releasing attachment, nor do I confine myself to the specific method of generating
an electric current herein described as I may employ any known source of electricity,
but what I claim and desire to secure by Letters Patent is :-
First In apparatus for the administration of a current of electricity whether coin
freed or otherwise the use of vertical pillars or columns and sleeves movable thereon
to serve as electrodes as well as regulators to the electrical current substantially as
herein described.
Second: In electrical apparatus the combination with the vertical columns herein
described and referred to in the preceding claim of a sleeve or collar capable of
moving freely and smoothly upon said vertical columns for the purpose of varying
the intensity of an electrical current substantially as herein set forth.
Third In combination with a coin freed electrical apparatus such as herein described
the adaptation thereto and employment therewith of a lock the bolt of which is caused
to overlap or cover the slot provided for the insertion therein of coins, tokens or the
like substantially as and for the purpose herein set forth.
Fourth In the electrical apparatus herein described the interposition into the
electrical circuit of a switch capable of being manipulated from the exterior of the
enclosing case by the person using the machine substantially as and for the purpose
herein set forth.
