Delivering Articles in Exchange.
I JAMES SALTER FARMER, of Adelphi Iron Works, Salford, in the County of
Lancaster, Engineer do hereby declare the nature of said Invention for IMPROVEMENTS
IN APPARATUS FOR RECEIVING COIN AND AUTOMATICALLY DELIVERING ARTICLES IN
EXCHANGE to be as follows:-
My invention consists in certain improvements in apparatus for the automatic
delivery of pre-paid articles and the chief object of my improvements is to prevent all
possibility of such articles being obtained fraudulently by ineans of iron washers or by
discs of lead or other soft metal as is frequently the case in apparatus of the present
construction.
To effect this object I dispense with the long balanced pivoted coin lever as employed
in some patented machines and substitute therefor two small elbow levers one of which
is pivoted on each side of the coin aperture with the free ends of the short arms
pointing inward. These levers are pivoted near the extremities of the long armis in
order to obtain the right balance for preventing any base coin or disc which may be
placed in the coin aperture from pressing the free ends of the short arms outward and
falling through to operate the machine. These small levers are magnetized so that
iron or any substance which can be attracted by them is held up in the coin aperture
until the levers are moved apart by the action of small cams, catches or other
mechanism and the iron washer or other counterfeit released at a point where it
cannot operate the machine.
For the purpose of detecting lead or other soft metal dises or washers I fit on one
side of the coin aperture a trigger or pivoted lever or other device provided with a

page_text: pin point or points. When the slide or its equivalent is worked to operate the machine
the trigger pivoted lever or other device comes in contact with a cam or catch and is
moved forward thereby causing the pin points to penetrate the lead or other soft
metal disc sufficiently to cause the latter to adhere to the trigger or lever until the
latter has been operated in the reverse direction by another cam or catch and caused
to release the disc at a point where it can drop through and escape without actuating
the machine.
In certain cases where required this trigger, pivoted lever or other detecting
device for soft metal discs may be placed on both sides of the coin aperture or apertures
instead of on one side only as above described.

Delivering Articles in Exchange.
I JAMES SALTER FARMER of Adelphi Iron Works Salford in the County of
Lancaster Engineer do hereby declare the nature of said Invention for IMPROVEMENTS
IN APPARATUS FOR RECEIVING COIN AND AUTOMATICALLY DELIVERING ARTICLES IN
EXCHANGE, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention consists in certain improvements in apparatus for the automatic
delivery of pre-paid articles and the chief object of my improvements is to prevent all
possibility of such articles being obtained fraudulently by means of iron washers or by
discs of lead or other soft metal as is frequently the case in apparatus of the present
construction.
To effect this object I dispense with the long balanced pivoted coin lever as
employed in some patented machines and substitute therefor two small elbow levers
one of which is pivoted on each side of the coin aperture with the free ends of the
short arms pointing inward. These levers are pivoted near the extremities of the
long arms in order to obtain the right balance for preventing any base coin or disc
which may be placed in the coin aperture from pressing the free ends of the short
arms outward and falling through to operate the machine. These small levers are
magnetized so that iron or any substance which can be attracted by them is held up
in the coin aperture until the levers are moved apart by the action of small cams
catches or other mechanism and the iron washer or other counterfeit released at a
point where it cannot operate the machine.
For the purpose of detecting lead or other soft metal dises or washers I fit on one
side of the coin aperture a trigger or pivoted lever or other device provided with
a pin point or points. When the slide or its equivalent is worked to operate the
machine the trigger pivoted lever or other device comes in contact with a cam or
catch and is moved forward thereby causing the pin points to penetrate the lead or
other soft metal disc sufficiently to cause the latter to adhere to the trigger or lever
until the latter has been operated in the reverse direction by another cam or catch
and caused to release the disc at a point where it can drop through and escape
without actuating the machine.
In certain cases where required this trigger pivoted lever or other detecting
device for soft metal discs may be placed on both sides of the coin aperture or
apertures instead of on one side only as above described.

page_text: Invention may be fully understood and readily carried into
effect I will describe the accompanying two Sheets of Drawings reference being had
to the figures and letters marked thereon.
Figure 1 is a longitudinal sectional elevation on the plane of the line C D Fig. 2 of
a postcard machine embodying my improvements.
Figure 2 is a transverse vertical section of the machine on the plane of the line A B
Fig. 1.
Figure 3 is a sectional plan on the plane of the line E F, Fig. 1.
Figure 4 is a transverse vertical section of the slide and slideway taken through
the coin aperture and
Figure 5 is a longitudinal vertical section of part of the slide showing the soft
metal detector and Figure 6 is an end view of the same.
Similar letters refer to similar parts throughout the several views.
In these views. -a designates the coin slide which is provided with a coin slit or
aperture a¹ and a knob or handle a² and is fitted and free to be moved in slideways b¹
in the frame b of the machine. The inner portion of the slide is made hollow and
preferably cylindrical in form to receive a piston or plunger c which is secured to
the frame 6 and thus forms a pneumatic check to prevent the slide from being
jerked rapidly backward and forward.
'
On the underside of the cylindrical portion of the slide a is formed a projection a³
which when the slide is being drawn out into the position shown in Figure 1 comes
in contact with a projection d' on a table d which is fitted and free to slide in a
frame b.
The sliding table d is recessed on each side where it is connected to a similar sliding
table e by two arms or levers f pivoted to the frame at so that when the table d is
moved in one direction the other table e is by the pivoted arms fmoved in the reverse
direction. There are on the upper table e two spring pieces g nicked or recessed at gl
and when the table e is being moved outward these nicks g₁ engage a postcard and
eject it partially through the delivery slit in the front of the machine.
The coin slide a works upon a table 62 forming part of the slideway b¹ in which
table is cut a slot upon the edges of which the coin inserted in the aperture a¹ is
supported if of the correct size but through which it drops without operating the
machine if too small in size.
The parts so far described with reference to the accompanying Drawings do not
form an essential feature in my present Invention but are simply given as an
illustration of a suitable arrangement of mechanism to which my Improvements may
be applied and in combination with which they may be used.
I will now proceed to describe those parts of the machine in which my said
Improvements are embodied.
Heretofore in machines of the class represented the operating mechanism for
effecting the delivery of the pre-paid article has been usually actuated by means of
the coin dropping upon and if of the correct weight depressing the front end of a
long balanced pivoted lever j indicated by dotted lines Figure 1 and one feature of
my Invention consists in dispensing with the said lever and substituting therefor a
pair of small hook or elbow levers k pivoted at to the slide a one on either side
of the coin aperture a¹. These levers are magnetized and are so pivoted and
balanced that they will cling to any iron or other metal washer for which
they have affinity and when the slide a is pushed into the machine the
levers support the counterfeit coin and prevent it from falling through to
operate the machine until the heels on the levers & come against the strikers or
catch pieces shown best in Figure 3 whereby the levers k are moved apart and
forced to relinquish their hold of the counterfeit coin which falls down into the
space m without having effected the delivery of a postcard.
When however the proper coin has been placed in the aperture a¹ and the slide
has been pushed a short distance inward the coin drops on to the edges of the
slot in the table 62 thereby pressing out the heels on the elbow levers k into

page_text: the position indicated by dotted lines Figure 4; as the slide a is pressed farther
inward and just before the coin leaves the edges of the slot and drops into the
space m each heel k² comes against a projection n fixed on the sliding table & so
that the table d is moved inward with the slide a and through the pivoted arms
f
moves the sliding table e outward and partially delivers a postcard through the slit h
from whence it may be completely withdrawn by the purchaser.
The above described improvements effectually prevent the fraudulent working of
the machine by means of iron washers or other washers made of metal attractable
by the magnetized levers and moreover an additional advantage is obtained by my
Invention the heels or projections on the elbow levers act as the keys for operating
the machine instead of the coin as now customary the objection to using the coin
for this purpose being that it is liable to be defaced or to be bent and to jam the
machine.
The improvement for detecting lead or other soft metal discs or washers consists of
the following or an equivalent arrangement of mechanism -A trigger or lever o
which is provided with a pin point or points o¹ at one end and is fixed on a stud or
pivot p free to turn on its axis; on the pivot p is also fixed a finger p' on the frame b
is fixed a catch piece s shown best in Figure 2 and below the slide à a plate spring t
is secured to the frame b¹.
When the slide a is pushed into the machine after a coin has been dropped into the
aperture a¹ the end of the pivoted trigger o comes in contact with the plate spring t
thereby moving the point of forward and if the counterfeit coin-be a disc of lead or
other soft metal the point is caused by this movement to penetrate the said disc
sufficiently to cause the latter to be suspended and kept from pressing the heels k²
outward to work the machine until the slide a has been pushed so far in that
the finger p¹ comes against the catch piece s and causes the pivot p to turn in the
reverse direction on its axis thereby withdrawing the point or points o¹ from the
spurious disc and allowing it to fall into the space m without having operated the
machine.
The plate spring t has sufficient rigidity to cause the pin point or points o' to
penetrate a lead or other soft disc but does not offer so much resistance as to
blunt or cause injury to the point or points when pressed against a coin or hard
washer.
In machines which are arranged to be operated by two coins and in certain
other cases where required I may employ two pivoted triggers or equivalent soft
metal detecting mechanism one placed on either side of the coin aperture.
I have shown and described my Improvements as applied to a machine arranged
for the automatic sale of post cards but I would have it clearly understood that my
said improvements may be applied to various types of machines adapted for the
automatic delivery or sale of many different articles. Again I have shown and
described a patented form of coin slide and one particular combination of mechanism
but it is obvious that my improvements may be used in combination with any
equivalent for the coin slide and with any other suitable arrangement of mechanism.
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. In apparatus for the delivery of pre-paid articles dispensing with the long
balanced pivoted coin lever and substituting therefor two pivoted hook or elbow levers
which are preferably magnetized substantially as and for the purposes herein set
forth.
2. The use and application of pivoted magnetized levers such as the elbow levers k
or any mere modification thereof in the manner and for the purposes herein described
