Improvements in Coin-controlled Automatic Apparatus for
Weighing, Lung-testing, and other Operations.
I, HENRY HARRIS LAKE of 45 Southampton Buildings, Chancery Lane, London,
County of Middlesex, 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 :-
This invention relates to that class of coin controlled machines in which a number
of different testing apparatus are normally controlled, to prevent their use, by devices
which may be released by a coin deposited in the machine, and has for its prime
object to have the controlling devices for all the apparatus of such character, that they
will all be simultaneously released, so as to permit a single use of each apparatus, but
which will be automatically locked or controlled against the second or further use of
the apparatus, without first depositing a coin in the machine.
Another object is to have the coin receiving devices of such a character that the
coin must be released thereby and deposited in the machine before any of the
apparatus is released and ready for use.
A further object is to combine in a single machine, a weighing apparatus, a spiro-
meter or lung tester, an electric apparatus for giving an electric shock, and a
mechanical motion apparatus, all connected with, and directly controlled by the coin
receiving devices.
Other objects are to have automatic locking devices for all these apparatus which
may be simultaneously released by the coin receiving devices so as to leave each
apparatus in position for a single operation when desired, but which will automatically
arrest the apparatus after such operation; and to provide certain novel details of con-
struction in carrying out my invention, to obtain these important results, all as
illustrated in the accompanying drawings, in which

Similar letters of reference indicate the same parts in the several figures of the
drawings.
In the description of the machine, we will describe the various apparatus separately,
beginning first with the coin-receiving devices, with which all of the apparatus is
connected and their operation controlled by the operation of the coin receiving
devices, without the previous operation of which none of the apparatus can be
employed.
Referring now to the drawings, and more particularly to Figs. 6, 7, and 8,
A B represent two parts of a sectional shaft placed end to end, and each part actuated
to rotate in one direction by coiled springs C, sleeved thereon and attached at their
ends respectively to the parts of the shaft and to a stationary portion of the bearing
or support for the shafts, each part of the shaft being held against the force of the
springs by stops of any suitable character, such as the radial arm D, projecting from
the part A, and bearing at its free end upon an adjustable screw stop E, and the
pin F, upon the crank arm G, secured to the outer end of the part or section B,
which pin works in a groove in a stop plate H, secured to the casing of the machine.
The inner end of the section A, opposing the section B, is provided with a longi-
tudinal slot I, of less length than the diameter of the coin to be employed, or with a
pocket to receive the coin on edge, either of which would subserve the intended
purpose of receiving and holding the coin upon the end of the shaft in which, how-
ever, it is assisted by the end J, of the section B, against which the edge of the coin
rests.
To this slot in the shaft, leads the coin chute K, from the front of the machine
located in convenient position for depositing the coin, to ensure the delivery of which
to the slot or cup in the shaft, the latter is provided with guide-wings L, at each side
of the slot, converging towards the slot.
The end J of the section B of the shaft is also provided with a lateral lug or pro-
jection M, just back of the slot, which when the said section of the shaft is turned by
the crank handle G, on the front of the machine will pinch the coin between it and
the opposite wall of the slot in the other section of the shaft, causing both sections of
the shaft to turn together, carrying with them the coin until the latter is suspended
above the coin receptacle N. At this point a pivoted dog O, which forms one branch
of a yoke. engages a notch or tooth P, in a collar Q, mounted upon the section A of
the shaft, thus temporarily locking that section of the shaft in that position against
the action of its controlling spring, so that when the section B of the shaft, or rather
the crank handle G thereof, is released, this section will start back alone in advance

page_text: of the other section under the influence of its controlling spring, and thus release the
coin, which then drops into the coin receptacle.
Before completing its return stroke, the shaft section B operates to release the
section A from the dog 0, by means of a cam R thereon, which rises under another
branch S of the yoke of which the dog O forms a part, thus lifting the dog so as to
clear the tooth on the collar Q, and thereby permit the section A to return to its
normal position under the influence of its controlling spring.
Thus it will be seen that the entire machine which is controlled by the coin receiving
devices, as will be hereinafter more fully explained, remains wholly inoperative until
the coin is deposited in the receiver, acting as a key to connect the two parts or
sections of the shaft, and that the coin, when once the shaft is turned to produce the
desired release of the various apparatus, cannot he retained in the receiver, but will
be automatically discharged therefrom, and that too before any of the apparatus can
be operated.
Upon the outer end of the part A of the sectional shaft, is mounted a disk T, or it
may be a crai k-arm, with which all of the other apparatus is directly or indirectly
connected, so that by the rotation of the shaft in depositing the coin in the receptacle,
the automatic locking devices of all the apparatus will be released so as to permit a
single operation thereof, each of which will now be described.
The weighing apparatus more clearly illustrated in figures 1, 2, 11, 12, 13 and 21,
consists of a platform scale a of sufficient dimensions to accomodate a single person,
projecting forwardly from the bottom of the machine, and upon which the person is
expected to stand while using all of the apparatus, which scale may be of any suitable
or desirable construction, as that forms no part of this invention, so long as it has
connected therewith a rod b affected by the movement of the platform so as to indicate
'the degree of extension of the weighing spring c, and indirectly the weight of the
person upon the platform.
upon the
To the upper end of this rod is secured a toothed rack d meshing with a pinion e
mounted loosely upon an arbor fjournalled in suitable bearings, and having secured
to its opposite or forward end an indicating hand g working about a dial
face of the machine as illustrated in Fig. 1, by means of which, the weight of a
person upon the platform may be indicated.
Upon the arbor is keyed a drum i over which works a cord j suspending a weight k,.
the gravity of which tends to normally rotate the drum, and consequently the arbor
to which the indicator is secured, which action, however, is prevented by means of a
dog pivoted to the arbor bearings, and arranged to engage a notch or tooth m upon
the periphery of the drum so as to normally maintain the latter in such position that
the indicator will stand at O upon the dial.
Upon the arbor between the drum and pinion is loosely mounted a disc n
having projecting from the opposite faces thereof, pins o and p, the former of
which lies in the path of movement of a ping projecting laterally from the side of
the pinion so as to be engaged thereby, and thus impart the rotary motion of the
pinion to the disc, while the latter projects into the path of movement of a pin r pro-
jecting laterally from the opposing face of the drum, so that the rotary motion of the
dise may in turn be imparted to the drum.
It will be noticed, however, by reference to Figs. 11 and 12 that these pins are so
disposed relative to each other, that the pin q on the pinion is in advance of the pin o
upon the disc, with reference to the direction of rotation imparted to the pinion by the
downward movement of the rack as a person steps upon the scale platform, and that
the pin p on the disc is in advance of the pin upon the drum, so that when a person
steps upon the scale platform, no movement of the weight indicator will take place
until the coin is deposited in the machine and the dog disengaged from the tooth m
on the drum, as described further on, for the only result will be that the pinion will
make almost a complete revolution upon the arbor before the pin q thereon, engages
the pin o on the disc at the rear side, and the pinion and disc will then together make
almost a complete revolution before being stopped by the engagement of the pin p.
with the pin which will not take place until the weight on the platfor.n is such that.
1"

page_text: the arbor when freed would have to make almost two complete revolutions, to indicate
it and this would require the weight of several persons, who could not be accommodated
upon the scale platform.
However, when the dog is released, as the result of depositing the coin in the
machine, the drum, under the influence of its weight, will be caused to rotate, carrying
with it the arbor and indicator, until the several pins are in engagement, when the
pin upon the pinion will indirectly act as a stop for the drum and indicator, thus
indicating the exact weight of the person upon the platform; and obviously, when the.
person steps off of the platform, the retractile force of the weighing spring will cause
the rack to rise and resume its normal position, and thus, through the medium of the
pinion and the pins before described, return the drum and indicator to their normal
position, where they will be caught and held by the dog.
The employment of the intermediate disc is optional, its only purpose being to
prevent injury to the parts from excessive weight upon the scale platform, and
obviously it may be dispensed with, and the pinion be made of such diameter that its
circumference will equal the length of the rack, and thus, can be caused to make only
a single revolution, indicating the maximum weight possible to be shown by the
machine, and a suitable stop be provided for relieving the indicating apparatus of
strain in the event that excessive weight is placed upon the platform, all of which will
be so well understood by one skilled in the art to which this invention appertains, that
it is not believed necessary to herein illustrate the same, or describe it more in
detail.
For releasing the dog, I employ a trip lever s pivoted upon a suitable bracket
attached to the casing of the machine, to the free end of which is pivotly secured a
gravitating finger t projecting under the end of the dog, and so constructed, that when
the lever is lifted the finger will engage and elevate the end of the dog, but when the
lever is lowered, the finger will fall back and pass by without affecting the dog.
This lever is operated by a rod u connecting it with one end of a lever r pivoted to
the machine casing, the opposite end of which lever is connected by another rod w
with the disc T upon the sectional shaft of the coin receiving device, eccentrically to
the axis thereof, so that when the shaft is rotated in depositing the coin, one end of
the lever will be depressed, and the other to which the rod u is attached, corre-
spondingly elevated so as to lift the trip and released the dog.
To prevent the use of the scales for weighing a number of persons for a single coin,
by holding the coin in the receiver and consequently holding the dog elevated, I pro-
vide the trip with an extension x projecting into the path of movement of a radial
army on the drum i, which latter, as the drum revolves will strike the extension, and
acting as a cam thereon, forcibly lift the trip and compel its release of the dog, the
trip for this purpose, as well as for permitting the return of the parts to their normal
position, having a pin and slot connection with the rod u.
A more simple and equally effective and the preferred measure for preventing this
repeated use of the machine, is illustrated by dotted lines in Fig. 2, and also in
Fig. 22, which consists in extending the trip beyond its pivot at the opposite side,
thus converting it into a lever of the first class, and attaching the rod u to the
extended end thereof, so as to hold the free end of the trip normally above the end of
the dog, in which case the dog will not be released until after the coin is deposited in
the machine, and during the return movement of the shaft of the coin receiver, upon
the completion of which movement the dog will be both tripped and released. Hence
with this construction, the extension and arm y may be dispensed with, for the
weighting apparatus can only be used once before it will be locked and require the
use of another coin for its release; but as long as the person remains upon the scale
platform, the weight will be indicated upon the dial.
The spirometer or lung tester (the location of which, and relative disposition of the parts
are illustrated in Fig. 2) is shown in detail in Figs. 9 and 10, and consists of a reservoir 1,
containing a suitably coloured fluid, preferably glycerine diluted with distilled rain-
water, connected at the bottom thereof by a tube 2 with an indicating vessel 3, located
upon the front, and preferably near the upper end of the machine, which is provided

page_text: with a scale 4 for indicating to the operator, through the medium of the liquid, the
force or strength test of the lungs. This vessel is in turn connected at the top thereof
by a tube 5, with an air-tight chamber 6 in which is located a spring seated on piston 7,
so that as the liquid is forced from the reservoir 1 into the bottom of the indicating
vessel, the air contained in said vessel will be forced by the liquid into the closed
piston chamber, or more properly compression chamber, lifting the piston therein
against the force of the spring so as to compress the latter, and correspondingly com-
press the air, this compression as a matter of fact, offering the real resistance to the
lung power.
The liquid is expelled from the reservoir by the direct action of the breath or lung
power of the operator, through the medium of a tube 8 provided with a suitable
mouth piece 9 suspended upon the outside of the machine casing in convenient position
for use, the inner end of which tube connects with the lower end of a piston
chamber 10, the purpose of which will be described further on, which latter a suitable
distance above the bottom, is connected by a tube 11, with a valvo chamber 12 which
in turn is connected by a pipe 13 with the top of the reservoir.
Within the valve chamber works a valve 14 fitting like a piston the interior of the
chamber, and provided at its centre with a passage 15 of small bore, leading from the
chamber to the pipe 13. This valve is of sufficient height to, when resting upon the
bottom of the chamber, close outlet ports 16 formed in the side walls of the chamber.
Hence, when the month piece is blown into, the air from the lungs of the operator
will pass through the tube 8, piston chamber 10, tube 11, valve chamber 12,
passage 15, and pipe 13 into the top of the reservoir, forcing the liquid therefrom, up
into the indicating vessel so as to compress the air contained therein in the manner
before described, and at the same time, indicate to the operator upon the scale 4
the strength of his lungs. Immediately he ceases blowing, however, the compressed
air will force the fluid from the indicating vessel back into the reservoir, thereby
causing the discharge from the reservoir of the air contained therein through the
pipe 13 but as the passage 15 in the valve 14 is of considerably less diameter
than the pipe 13, the air will act upon so as to lift the valve in its chamber, and
thereby open the discharge port 16, thus permitting the escape of the air without the
necessity for passing back through the mouth-piece and tube.
.
To prevent the use of this spirometer or lung tester without first depositing a
coin in the machine, I provide in the piston chamber 10, a piston 17, the rod or
stem 18 of which passes freely through the head of the chamber cylinder, and is
opposed by a stop 19 which when the mouth-piece is blown into without first
depositing a coin, will prevent the rising of the piston 17 in its chamber sufficiently
to open the end of the tube 11 which thus prevents the air from reaching the reservoir,
and of course prevents the use of the spirometer.
This stop is in the shape of a bell-crank lever, one arm 19 of which projects
horizontally into the path of movement of the rod 18, while the other arm hangs in
substantially a vertical position, and has a weight 20 secured thereto for the purpose
of normally maintaining and restoring the stop to the position shown by full lines in
figure 9, in the point of movement of the piston rod.
This stop is pivotly secured to a drop plate 21 pivoted to a bracket projecting from
the piston chamber, and extended or weighted on the opposite side of the pivot from
the stop so as to normally maintain both the plate and stop in the elevated posi-
tion shown by full lines in Fig. 9 with the weighted portion bearing upon a
suitable rest 22 of any character that will prevent further movement of the plate
in that direction. `-
This plate is also provided with an arm or extension 23 adapted and arranged,
when the plate is swung upon its pivot and dropped to the position shown by dotted
lines, to project into the path of movement of the piston rod. From the side of the
plate projects a lug 24 upon which rests, and with which engages hook 25 upon the
free end of a connecting rod 26, eccentrically pivoted at its opposite end to the disc T
upon the shaft of the coin receiving device.
Thus when the shaft is rotated, in the act of depositing the coin in the machine, it

page_text: will, through the medium of the connecting rod, swing the drop plate upon its pivot,
causing it to drop to such position that the stop will be out of the path of movement
of the piston rod, while the extension 23 will lie in the path of movement of said rod,
and the parts will remain in this position with the spirometer now unlocked, until it
is desired to use the same. The first result of blowing into the mouth-piees, is to
elevate the piston sufficiently to open communication with the pipe 11, and consequently
with the reservoir, which action of the piston causes the rod thereof to strike against
the arm 23 of the drop plate, and elevate and restore said plate to its normal position,
the stop at this time being below the end of the rod, and held in close relation thereto
by its weight.
When the operation is completed and the air is no longer forced into the piston
chamber, the piston will fall back to its normal position by gravity, to the bottom of
its chamber, and as soon as it passes below the stop, the latter, under the influence of
its weight will swing out to its normal position in the path of movement of the piston
rod, and thus prevent a further use of the spirometer without first depositing a coin
in the machine.
This locking device is automatic in its operation, both as to its releasing and
locking the apparatus controlled thereby, for the act of depositing the coin in the
machine releases the lock and sets the parts in position for use, while a single
operation of the machine, automatically restores the parts to their normal position
so as to lock the apparatus against fnrther use.
Electric-shock apparatus is illustrated in detail in Figs. 14 to 20 inclusive, while its
location and arrangement with reference to the other apparatus contained in the
machine is illustrated in Figs. 1 and 2. It consists generally of a metallic bar 27,
provided in the middle with insulating material and of ornamental finish if desired,
supported upon a suitable bail, or upon arms 28 pivotly secured at their lower ends to
brackets 29 secured to the front of the machine casing, as more clearly illustrated in
Fig. 1, in convenient position to be held by the operator while standing upon the
scale platform.
With this bar, about the centre of its length, is connected one end of a chain or
cable 30, the opposite end of which is wrapped about, and secured to a drum 31,
fixed upon a short shaft 32 attached to the inner side of the machine casing, lying
parallel with the hand-bar 27, the said shaft being loosely journalled in suitable
brackets, and having sleeved thereon a coiled spring 33, the ends of which are secured
respectively to said shaft and the casing of the machine, so that the torsion of the
spring tends to rotate the shaft, and thereby wind the cable or chain upon the drum,
and thus draw the hand-bar up against the casing. To save wear and avoid friction,
an anti-friction roller 34 is journalled in the casing at the bottom of the slot therein,
through which the chain passes, and over which pulley the chain works when the bar
is drawn outwardly by the person upon the scale platform.
Upon the shaft 32, towards the opposite end thereof, is mounted another drum 35
to which is secured one end of a cord or cable 36, the lower end of which (see
Figs. 2, 15 and 16) is secured to the end of a bar 37, which bar is in turn secured to
the core 38 of an electrical induction coil 39, which may be of any suitable or
desirable construction, and connected with the battery 40, and the hand-bar in any
suitable manner, such as that illustrated in diagram in Fig. 2, so long as the electrical
current generated thereby, is conducted to the hand-bar.
The two drums upon the shaft 32 have their respective cables attached thereto in
such manner, that as the hand-bar is drawn out from the casing unwinding the cable 30,
the same action will wind the cord 36 upon its pulley and correspondingly draw out
the usual sliding core of the induction coil, thereby increasing the force of the
electric current or shock produced thereby, in proportion to the degree of movement
of the hand-bar, and consequently of the core of the coil, as usual in electrical
apparatus of this class.
In order to indicate to the operator the strength of the electric current, I provide a
laterally extending arm or bracket 41, secured to the bar 37, to the end of which
bracket is rigidly secured a rod 42, to the upper end of which is attached a rack-

page_text: bar 43 gearing with a toothed wheel 44 on an arbor 45 journalled in the casing, upon
the outer end of which arbor is secured an indicator 46 working over a dial 47 upon
the front of the machine, upon which is represented the desired numbers indicating the
strength of the electric shock.
While the strength of the electric shock is wholly within the control of the operator
as before described, the duration thereof in any degree of strength is determined by
the apparatus; for it is one purpose of this invention to have this electric-shock
apparatus controllable by the coin receiving devices in such manner that it may be
released automatically by the depositing of the coin in the machine, but still be auto-
matically locked against a further use, and the electric circuit through the handle
simultaneously broken after a single use thereof, for a predetermined length of time.
This is accomplished by means of the mechanism more particularly illustrated in
Figs. 14 to 17 inclusive, in the former of which is shown a train of cogs or clock work
of any suitable character actuated by springs or weights, upon the winding drums or
shafts 48 of which are mounted master cog wheels 49 and 50, while upon a shaft 51
of the train of cogs carrying the cog wheel 52, is a notched disc 53, this shaft 51
acting as a governor for the speed of the mechanism, and either having the usual fan
secured thereto, or preferably a pitman 54 eccentrically pivoted at one end to the
disc 53, and at its opposite end to a piston rod 55 working in a small dash-pump 56,
the construction of which is immaterial, as the governing of the speed of the mechanism
is the only function which this device is expected to perform, and as before stated,
it may be substituted by any other suitable device that will perform the same
function.
With a shoulder 57 upon the disc 53, engages one arm 58 of a bifurcated dog 59
pivoted to the frame supporting the clock mechanism, while the other arm 60 of the
dog lies between the two prongs 61 and 62 of a pivoted catch 63, the prong 61
serving as a stop for the dog, the arm 60 of which rests thereon, while the catch 63
rests upon a pin 64 projecting from the casing of the machine.
Upon the pivot 65 of the catch is also mounted a trip 66 provided at its outer free
end with a pivoted finger 67 adapted and arranged to pass by a bend 68 in, or a
projection upon the arm 60 of the dog, but in its return movement will engage the
dog, lifting the same so that the arm 58 thereof will release the notch or shoulder 57
upon the disc 53, and at the same time the catch through the medium of its prong 62,
will be swung upon its pivot by the arm 60 of the dog, until the said arm clears the
prong, when the catch will fall back to its rest upon the pin 64, and the arm will be
caught upon the end of the prong 62, and held in an elevated position so that the
arm 58 of the dog will be held out of the path of movement of the shoulder 57,
leaving the clock work free to operate.
This result is attained by connecting the trip 66, through the medium of the rod 69,
with the lever r, which is in turn connected by the rod w with the disc T upon the
shaft of the coin-receiving devices; and it will be observed that the connection of
these rods, levers and the trip are so arranged that the dog is not released until the-
return movement of the shaft after releasing the coin, and hence this apparatus, like
the other previously described, cannot be used until after the coin is deposited in the
machine.
Immediately the dog releases the shoulder on the disc 53, the clock mechanism
under the influence of its weights or springs, begins to operate, and except the tem-
porary interruption of its operation produced for the purpose of suspending the
operation of the machine until the operator is prepared to use this apparatus, will
continue to operate until a pin 70, upon the master cog 49, engages and elevates the
catch 63, until the prong 62 thereof releases the arm 60 of the dog, when the latter
will fall by gravity to the position shown by full lines in figure 14, with the arm 58
thereof, projecting into the path of movement of the shoulder 57 upon the disc 53,
thereby serving to arrest the motion of the clock work, and automatically lock the
apparatus against further use without first depositing a coin in the machine.
Returning now to follow the consecutive steps in the operation of this apparatus,

page_text: when the disc 53 is released by the dog, and the clock-work begins its operation, the
working will continue until a pin 71 upon the master cog 50 of one of the winding
drums clears and releases the end of a pivoted lever 72, the free end of which,
through a pin 73 or other suitable connection, normally holds another and spring
actuated dog 74 out of the path of movement of the shoulder 57 on the disk, when
the said spring actuated dog being thus released, will project into the path of move-
ment of the shoulder upon the disc and temporarily arrest the working of the
apparatus after the disc has made one or two revolutions.
With the parts in this position, the apparatus is ready for use by the operator when-
ever he sees fit to pull on the handle bar, for by the movement of the dog 74 upon the
release of the lever 72 the said lever is swung upon its pivot, and being connected by
a rod 75 with a crank arm 76 upon the shaft 77 of a circuit making device the
terminals of the electric circuit will be placed in such relative position that the circuit
will be completed upon the slightest movement of the bar 37, through the medium of
the handle bar, as heretofore described.
This circuit making and breaking device consists of a spring contact plate 78,
located in close proximity to the sliding bar 37, so that when uncontrolled, it, or a
projecting lip 79, thereon will bear against the side of said bar, which constitutes
one terminal of the electric circuit, while the spring contact 78, constitutes the other
terminal.
When the parts are in operative position shown in the drawings, the spring contact
plate 78, is held out of contact with the bar 37 by means of a radial finger 80 upon
the shaft 77; but, when the parts are operated as just described, and the lever 72 is
caused to swing upon its pivot, it will through the medium of the rod 75, crank arm 76,
and shaft 77, withdraw the finger 80 from engagement with the spring contact plate,
and permit the latter to swing over to its natural position with the tongue 79 thereof
lying in a recess 81 in the side of the bar 37, but not in contact with the bar. As
soon, however, as this bar is elevated slightly by the action of the hand bar 27, the
tongue 79 and bar 37 will make contact so as to complete the electric circuit, and
remain in contact with each other during the vertical movement of the bar until the
lever 72 is engaged by another pin 71 upon the master cog 50 restoring it to its
normal position shown in fig. 14, when the circuit will be again broken by the movement
of the contact plate through the devices described.
The duration of the electric shock is altogether controlled by the action of the
clock-work, which although arrested by the action of the dog 74 when the parts are
put in the position described for completing the electric circuit by the operation of
the handle bar, this same operation of the handle bar simultaneously with its closing of the
electric circuit, releases the clock work from the dog 74 by means of a cam 82 upon a
rod 83 also secured to the bracket 41 attached to the bar 37, which cam engages a pro-
jection 84 upon the dog 74 as soon as the bar 37 starts to rise, forces the dog back so as
to release the shoulder on the disc, and the clock work will then continue its operation
while the electric circuit is complete until it is stopped by the action of the dog 59
before described, at which time the pin 71 has operated the lever 72, so as to auto-
matically break the electric circuit simultaneously with the stopping of the apparatus.
Thus it will be seen that this apparatus, like those previously described, may be
automatically released by the depositing of a coin in the machine so as to leave the
parts in position for operation at the will of the operator, but which, after making
single operation will be automatically locked against further use without first depositing
a coin in the machine, the electric circuit being simultaneously made and broken with
the releasing and locking of the apparatus.
a
The mechanical movement which is illustrated in detail in figs. 3, 4, and 5 is
designed principally for its attractiveness, and is arranged behind, so that its operation
may be observed through, the dial of the electric-shock apparatus, and may be of any
suitable character that will subserve the intended purpose, that shown in the drawings
representing a fanciful electric engine or motor which may be associated in the mind
of the operator with the working of the apparatus, although, as a matter of fact, it is
.

page_text: dependant for its operation solely upon the clock mechanism of the electric-shock
apparatus and works only when this mechanism is operated.
In this instance it is shown as a base 85 centrally located, on which is mounted
pillars 86 supporting an arch 87, which pillars and arch are wound with insulated
wire in imitation of electric apparatus. On each side of the pillars is a revolving
spool and fan 88, while above each of these is located a set of spools 89, and
below them a coil or spool 90 of an imitation electro-magnet with vibrating
armatures 91.
The revolving spool and fan, and also the vibrating armatures, are operated by
means of a large driving cog-wheel 92 mounted upon a counter-shaft 93 which has a
gear connection 94 with the cog wheel 52 of the clock work, the said cog-wheel 92,
meshing with pinions 95 upon the shaft of the spools 88 while the armatures 91 are
pivoted in any suitable manner, preferably being hung from the shaft 93 by the
hanger 96, and vibrated thereon by pins 97 upon a disc 98 engaging a projecting
finger 99 from the centre of said arm.
Upon the shaft 100, upon which the gear 94 is secured, there is mounted near the
forward end a segmentally coloured disc 101, which works within the base 85, to
attract attention, while around the edge of this disc, and secured to the face of the
base, is an annulus 102, representing a race-track in front, or over which travel
four horses 103 mounted by jockeys and carried upon the ends of radial arms 104
projecting from hubs 105, loosely mounted upon the forward end of the shaft 100,
each of which gains a momentum as a result of the rotation of the shaft, which
causes them to continue to revolve upon the shaft after it has stopped rotating, the
horses travelling about the race-track, and gaining and losing upon each other,
after the manner of a race.
Each of the arms is provided with a spring actuated pawl 105 engaging a
ratchet 106 fixed upon the shaft 100 by means of which, the rotary action of the.
shaft is imparted to the hubs, which revolve in unison therewith until the shaft ceases
its rotation, which is sudden, because of the peculiar stop employed, when the
momentum of the arms and horses will cause them to continue revolving about the
shaft with varying speed for some little time.
As before described, the sole purpose of this mechanical motion, is to render the
machine as attractive as possible, and the character of the movement is therefore
immaterial, and may vary considerably, and in fact be wholly different from the
mechanism shown and described, so long as it subserves the intended purpose, so long
as it is dependent for its operation upon, and co-operates with the clock mechanism of
the electric shock apparatus.
From the foregoing description of my coin controlled machine, it will be seen that
all of the apparatus while capable of separate individual operation at the will of the
operator, are all connected with, and dependent upon the coin receiving devices for
their release from their automatic locking mechanism, and that while each apparatus
is released simultaneously with all the others by the same devices, each will be
automatically locked after a single use thereof against a further use without first
depositing a coin in the machine; and further, that none of these apparatus can be
surreptitiously used even a single time, for they cannot be released until the coin is
actually deposited in the machine.
I am aware of Everitt's Patent No. 16,433 A.D. 1884 and make no claim to
anything therein described and claimed.
