Improvements in Apparatus for Detecting or Preventing Fraud in
Automatic Machines Operated by the Action of a Coin.
I, EDWARD PHIPPS APPLEYARD of 37 Harrietta Street, Hightown, Manchester in
the County of Lancaster, Engineer, do hereby declare the nature of my said 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 improvements in apparatus for detecting or preventing
fraud in automatic machines operated by the action of a coin.
Fig. 1 is a sectional side elevation of my invention-Fig. 2 is a front view of
same- Fig. 3 is a front sectional elevation-Fig. 4 is a sectional side elevation of my
invention with a single eccentric or elliptical wheel for arresting lead or other soft
counterfeits Fig. 4A is a part sectional side elevation shewing serrations in the
money slot-Fig. 5 is a sectional plan through line A' B' in Fig. 4-Fig. 6 is a front
view of my invention with front plate removed to show coin passage, with a pair of
eccentric or elliptical wheels for arresting lead or other soft counterfeits-Fig. 7 is a
sectional plan through line D' in Fig. 6-Figs. 8, 9, 10, and 10 A are sectional
elevations of other modifications of my improved apparatus for arresting lead or
other soft counterfeits-Fig. 8 A is a front elevation of Fig. 8-Fig. 8B is a plan
of Fig. 8 A-Fig. 11 is a sectional plan through line E¹ G' in Fig. 10-Fig. 12
is a modification of my invention on the horizontal principle-Fig. 13 is a part
front view of same-Fig. 14 is a sectional plan through line H in Fig. 12-
Fig. 14 A is a part sectional elevation of my invention on the horizontal principle
with a fixed magnet above the coin slot or passage, and Fig. 15 is a sectional
elevation of a modification of my invention wherein the magnet is carried by a
spring.
In all the figures the same letters are used to indicate corresponding parts.
In the case A of the automatic machine I provide the chamber B with the
bearings C, in which are mounted the journals D of the centre E carrying the
magnet F. The latter is mounted on the centre E in such a manner as to cause
it to rest against the stop G, so as to remove the catches or projections H clear of
the coin passage I. The coin passage I is provided with the slots J to allow the
catches H of the magnet F to block the passage I in case iron counterfeits are
inserted. In case iron counterfeits, for which the magnet F has an affinity, are
placed in the coin passage I the poles K with the catches or projections H are drawn
through the slots J as shown in dotted lines in Fig. 1, by which the passage I is
blocked, at which point they will remain until the metallic or iron counterfeit is
removed from the coin passage I. The catches or projections H are inclined
upwards as shown to prevent the magnet F being pressed back by forcing iron
counterfeits thereon. In case a genuine coin is inserted in the passage I the
magnet will not be attracted from its position of rest, by which the coin is allowed
to drop down and release the operating mechanism of the machine.
If desired the magnet F can be mounted on the spring W attached to the pivoted
or fixed centre E. In this case the underside of the catches or projections H àre
notched or inclined as shown in Fig. 15, which, when the magnet. F has been drawn
forward by an iron counterfeit, rests on the edges of the slots J, and thus prevents
the magnet F being pushed back by the pressure imparted to the counterfeit. To
prevent counterfeits such as lead, paper, and other soft materials being pushed into
ID 37

page_text: the machine I provide the eccentric or elliptical wheels L mounted on the centres M
in the bearings N. The eccentric or elliptical wheels L are held in position in the
slots or bearings N by the springs P. In case a genuine coin is inserted in the
passage I it will press or force the eccentric or elliptical wheels L back sufficiently to
allow it to be passed between the front plate X, or the serrations X mounted thereon
and the said wheel or wheels; the horizontal slots or bearings N being provided for
the purpose. If
a lead, paper, or other soft counterfeit is inserted in the coin
passage I the teeth of the eccentric or elliptical wheels L will grip the same, and the
more pressure there is put upon the counterfeit the gripping power of the wheels L
will be increased in proportion.
In another modification I employ two or more eccentric or elliptical wheels L,
opposite each other, and so fixed as to allow of a genuine coin to pass between them
and fall down the passage I as in Fig. 8. The centres M carrying the eccentric or
elliptical wheels L are provided with the arms L' which operate on the springs S
when the wheels L are rotated by a coin or counterfeit. The springs S are employed
to re-set the eccentric or elliptical wheels L to their normal position ready for the
next coin or counterfeit.
In this arrangement, if a soft counterfeit is inserted the teeth of the wheels L will
grip the same, and as the counterfeit is pressed downwards the wheels L will swivel
on their centres M and direct the counterfeit to the passage R leading to a receptacie
provided for such articles, or outside the machine as desired.
In another arrangement the eccentric or elliptical wheels L are mounted as in
Figs. 10 and 11, wherein the centres M are provided with the springs S. In this
case the wheels L will allow the coin or hard counterfeit to pass between them to the
upper side of the springs S as shown. In case a genuine coin or a hard metallic
counterfeit is inserted and the teeth of the wheels L cannot insert themselves the
springs S will give way or yield and allow it to be pressed through, but in case a
soft counterfeit is inserted the pressure on the springs S will increase the gripping
power of the teeth of the wheels L. In case a metallic or iron counterfeit is pushed
pass the wheels L it will be arrested in its descent through the passage I by the
poles K and the catches or projections H of the magnet F.
To ensure of the eccentric or elliptical wheels L being operated I mount them in
close proximity to each other and provide their peripheries with the ledges L² formed
by cutting away part of the circle. The ledges L² are so close as to prevent the
admission of a genuine coin or an iron counterfeit without operating the said wheels L ;
the latter being re-set by the springs S.
When my invention is constructed on the horizontal principle the pivoted magnet F
is held against the stop G by the spring U to allow genuine coins, when pushed
through the inlet passage or slot I, to tilt and fall down the passage I to the operating
mechanism of the machine as shown in Fig. 12. In case an iron counterfeit is
inserted in the inlet or slot I the magnet F will at once arrest it and prevent it
tilting over into the passage I, where it will remain until withdrawn, after which
the spring U will at once raise the magnet F against the stop G. In this arrange-
ment the eccentric or elliptical wheel L is mounted as shown to arrest soft counterfeits.
In conjunction with the eccentric or elliptical wheel L the wheel L centrally pivoted
can be mounted above the coin slot I as shown, or the arrangements shown in Figs. 10
and 11 can be employed. In this arrangement the eccentric or elliptical wheel L is
fitted with the springs S extending in the path of the coin or counterfeit when
pushed in the slot I, thus ensuring of the wheels L being operated. Immediately
the springs S are liberated the eccentric or elliptical wheel L will assume its normal
position ready to receive the next coin or counterfeit. The chamber V carrying the
wheel L is considerably narrower than the diameter of the coin intended to operate
the machine to ensure of the coin being pushed in sufficiently far to tilt over the
passage I; at the same time allowing of the withdrawal of counterfeits. Fig. 14 A
is another modification of my invention on the horizontal principle wherein the
magnet F is disposed over the coin slot I to prevent the falling of an overbalanced
iron counterfeit when the major portion has passed the point I. The magnet F may

page_text: De uxed or movable, and so disposed in the machine as to retain iron counterfeits
opposite its own poles until displaced by a genuine coin.
Fig. 16 is a part sectional elevation of another modification of my invention
wherein the magnet F is operated by the action of a counterfeit on the spring or
springs S employed for operating the eccentric or elliptical wheels L. To the case A is
pivoted the double spring or lever O' by the pin P¹. One end of the double spring or
lever O extends over the eccentric or elliptical wheel L; the opposite end resting
against the back of the magnet F. When a counterfeit is inserted in the slot I it
depresses the spring S and raises the eccentric or elliptical wheel L, and operates
the double spring O', which action causes the opposite end of the same to press the
poles K and catches H of the magnet F through the slots J into the passage I.
Immediately the spring S is liberated from pressure the eccentric or elliptical wheel L
assumes its normal position on its seat R¹.
Fig. 17 is a part sectional elevation of this part of my invention on the horizontal
principle. In this arrangement the eccentric or elliptical wheel L operates on the
counterfeit the latter, by the pressure from the wheel L raises the upper eccentric
or elliptical wheel L The latter is provided with the slot S₁ to allow it to rise on
the fixed centre T. When the upper eccentric or elliptical wheel L rises it operates
the double spring or lever O' and depresses the magnet F as before described.
In each modification the chamber carrying the wheel or wheels L is considerably
narrower than the diameter of the coin, to ensure of the latter being pushed past the
wheel or wheels L as in Figs. 8 A, 8 B, 12, 13, and 14.
I am aware of the Specification of Letters Patent granted to Anthony Harris
No. 8098 of 1888 and I wish it to be understood that I do not claim anything described
and claimed therein.
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. The combination with the money slots of automatic machines, of eccentric or
elliptical wheels so arranged that while they will allow of the passage of genuine coin
into the machine they will grip into the face or faces of soft counterfeits so as to hold
or prevent them being passed down the money slots leading to the operating
apparatus of the machine, substantially as described and as illustrated in Figs. 4, 5,
6, 7, 8, 9, 10, 10 A, and 11 of the accompanying drawings.
2. The combination with the money slots of automatic machines, of eccentric or
elliptical wheel L with the springs S and the centrally pivoted wheel L, so arranged
that while they will allow of the passage of genuine coin into the machine they will
grip into the faces of soft counterfeits so as to hold or prevent them being passed
down the money slot leading to the operating apparatus of the machine, substantially
´as described and shown on the drawing in Figs. 12 and 14.
3. The combination with the money slots of automatic machines, of the eccentric
or elliptical wheels L and the springs Š, substantially as described and shown on the
drawings for the purpose specified.

tions X, substantially as described and as shown on the drawings in Fig. 4 A for
the
purpose specified.
6. The combination with the money slots of automatic machines, of the fixed or
pivoted magnet disposed over the coin slot and so arranged that while it will allow
genuine coin to tilt into the passage leading to the operating apparatus of the
machine it will hold or prevent the falling of over-balanced iron counterfeits, substan-
tially as described and illustrated in Fig. 14 A of the accompanying drawings.
7. Operating the magnet F by the action of a counterfeit when inserted in

page_text: the money slot I, substantially as described and shown on the drawings in Figs. 16
and 17.
8. The use of the pivoted double spring or lever O¹, applied and operated substan-
tially as described and shown on the drawings in Figs. 16 and 17 for the purpose
specified.
