Improvements in the Method of Preparing or Protecting Postage
Stamps for Automatic Delivery, and in Machinery or Apparatus
for Automatically Delivering the same in Exchange for Coin,
Parts of which Improvements are Applicable to other Automatic
Delivery Machines.
I BERNARD AMBROSE COLLINS of 30 Stanley Street, Battersea, in the County of
Surrey, Meteorologist do hereby declare the nature of this invention to be 'as
follows:-
The objects of my invention are firstly, to protect the postage stamps against
atmospheric influence whilst they remain in the automatic delivery apparatus.
Secondly, to prevent a stamp or other articlo being delivered upon the insertion of
a coin other than that representing its value.
Thirdly, to render it impossible to abstract a stamp or other article from the
delivery orifice without payment of its value.
Fourthly, to prevent the possibility of the delivery mechanisin being put in motion
either by the insertion of a coin suspended by a length of twine or wire or by any
other means.
In carrying out the first part of my invention I enclose each stamp in a separate
envelope or cover.
For this purpose I take by preference 'a sheet of cardboard, wood, soft metal or any
other suitable material in length the full width of a row of twelve postage stamps as
they are now printed in sheets and in width three times the length of a postage stanip,
and this sheet is scored or indented lengthwise so as to divide the width into three
equal parts without separating one from the other completely.
I now take a single row of twelve postage stamps and place it in the centre of the
sheet so defined by the scorings or indentations before mentioned and I then fold over
the other parts and lightly seal them with gun or other suitable cement, thereby
forming a long envelope or cover having within it twelve postage stamps.
This long package 1 place in a suitable cutting machine and divité into twelve
packages each containing a perfect stamp.
These packages which are approximately of the size of a postage stamp are collected
and piled one upon the other in a separate metal casing of the same area and of
suitable length. This casing which might conveniently contain about three hundred
stamps, is then closed at one end by a pasteboard or other suitable plug, its other end
being sealed by means of a metal cap, a weighted follower having been previously
placed upon the pile of packages and it is then placed in the machine, and the
pasteboard plug removed.
I will now describe the mechanism by the aid of which I deliver a single stamp
from a pile arranged as above stated, and also the means I employ in carrying out the
second part of my invention.
I place the mechanism by preference in a metal box of any suitable size and if
desired so formed and arranged that it may be bolted to a pillar letter box:
In the front portion of this box [ form or arrange a receptacle or guides into which
the casing containing the cut packages of postage stamps before described may be
inserted.
Immediately below this, or at the lower end of the before mentioned casing, I form
a horizontal slot in the outer wall of the box, of proper size to allow of the free
passage of one of the card packages containing a postage stamp and level with the
lower side of this slot I arrange on the inside of the box a table upon which each
package containing a stamp. rests before it is pushed out as will be described:

page_text: In order to push a package of the pile out through this slot I employ a pusher which
is at one end of less thickness than the package and I give the necessary to and fro
motions to this pusher by means of a lever or combination of levers, or they might
be cams, which upon being moved by the hand through suitable connections extending
to the outside of the box give a forward movement to the pusher so as to push out. a
package containing a stamp, and it is then returned to the normal position preferably
by means of a spring or weight. The said pusher is prevented moving forward until
the proper coin is dropped into a slot in the box, by means of a latch or bolt normally
held in engagement with some part of the pusher by a spring or weight but capable
of being withdrawn at the times desired as hereinafter described.
In the top of the box or it might be at the side thereof 1 form a slot of a size
suitable to admit of the insertion of the coin. Within the box at the upper part
⚫ thereof I mount horizontally in bearings with capability of revolving a cylinder
through which is formed a slot of a size to admit of the passage of the coin. This
cylinder is capable of revolving on its axis sufficiently to change the position and
alignment of its slot with the slot in the box and it thereby closes such slot, but it is
normally held with its slot in alignment with the slot of the box by means of a spring
or otherwise.
Below the cylinder I arrange a kind of hopper through which the coin passes and
at one side of this hopper I pivot a grooved bar in such a manner that by the aid of a
spring it will normally obstruct the passage of the coin. To this bar I connect one
pole of an electric battery whilst to the other side of the hopper or some part carried
thereby I connect the other pole of the battery, such battery being located in the back
. or other convenient part of the box.
On the axis of the slotted cylinder at each end thereof I fix an arm or lever. One
arm or lever is connected either directly or through suitable intermediate connections
with an armature of an electro-magnet which is in turn connected with the battery
before mentioned. The other arm or lever is connected in the same manner with the
latch or bolt which prevents the forward movement of the pusher acting upon the
stamp packages so that the rotary motion of the slotted cylinder controls the release
of the pusher.
The grooved bar which obstructs the passage of the coin through the hopper after
it has passed through the slot of the cylinder I by means of suitable connections,
connect with the pusher in such manner that when the pusher is moved the grooved
. bar will be withdrawn from the coin and allow it to pass into the money compartment
below.
P
The following will illustrate the operation of the above described mechanism
--
If, say, a penny be inserted into the slot in the box it will pass through the slot of
the cylinder into the hopper and will be obstructed in its passage by the grooved bar.
Here it will close the circuit of the battery and electro-inagnet with the result that
when the amature is drawn toward the magnet it will through its connection with the
lever of the cylinder cause the cylinder to turn on its axis and thereby close the slot
of the box, as it will present a solid surface thereto. The movement of the cylinder
upon its axis will cause the lever at the other end thereof to withdraw the latch or
bolt from the pusher and when the lever or other connection on the outside of the box
is moved by the hand it will cause the pusher to move forward with the result that a
postage stamp package will be pushed out. At the same time the connection between
the grooved bar, which stops the coin, and the lever or other outside connection
operated by hand is such that when the latter is moved, the grooved bar is drawn
back and the coin falls through into the money compartiment. The circuit being
broken, the cylinder returns to its normal position and the latch or bolt springs
forward, so that when the pusher returns to its normal position it is locked and
cannot be moved until another coin is inserted to make contact and thereby
release it.
Should an attempt be made to tamper with the apparatus by means of a coin
attached to a string or otherwise the cylinder will not revolve the required distance so
that the latch or bolt will not be withdrawn from the pusner but the cylinder will

page_text: nip the string or other connection and prevent the withdrawal thereof and of the
coin.
In carrying out the third part of my invention I insert in the slot through which
the stamps are pushed out, two or more small springs or spring teeth so arranged that
they will in no way interfere with the proper outward movement of the stamp packages
but will offer every obstruction to the fraudulent abstraction of packages from
without.
The fourth part of my invention I accomplish by placing in the electric circuit
an electric bell so that when the circuit is completed by a coin the bell rings and
continues to do so until the coin if properly inserted falls through to the money
compartment or if the coin be attached to a string or otherwise, until it is removed by
an authorized person.
I may also employ an indicator either in connection with the revolving cylinder or
the electro-magnet and thereby record the number of stamps delivered.
It will be evident that parts of these improvements are applicable to other
automatic delivery machines."

Improvements in the Method of Preparing or Protecting Postage
Stamps for Automatic Delivery, and in Machinery or Apparatus
for Automatically Delivering the same in Exchange for Coin,
Parts of which Improvements are Applicable to other Automatio
Delivery Machines.
I BERNARD AMBROSE COLLINS of 30 Stanley Street, Buttersea, in the County of
Surrey, Meteorologist, 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 objects of my invention are firstly to protect the postage stamps against
atmospheric influence whilst they remain in the automatic delivery apparatus.
Secondly, to prevent a stamp or other article being delivered upon the insertion
of a coin other than that representing its value.
Thirdly, to render it impossible to abstract a stamp or other article from the delivery
orifice without payment of its value.
Fourthly, to prevent the possibility of the delivery mechanism being put in motion
either by the insertion of a coin suspended by a length of twine or wire or by any
other means without giving an audible indication.
In carrying out the first part of my invention 1 enclose each stamp in a separate
envelope or cover.
For this purpose I take by preference a sheet of cardboard, wood, soft metal or any
other suitable material in length the full width of a row of twelve postage stamps as
they are now printed in sheets and in width three times the length of a postage stamp,
and this sheet is scored or indented lengthwise so as to divide the width into three equal
parts without separating one from the other completely.
I now take a single row of twelve postage stamps and place it in the centre of the
sheet so defined by the scorings or indentations before mentioned and I then fold over
the other parts and lightly seal them with gum or other suitable cement thereby forming
long envelope or cover having within it twelve postage stamps.
a
This long package I place in a suitable cutting machine and divide into twelve
packages each containing a perfect stamp.
These packages which are approximately of the size of a postage stamp are collected
and piled one upon the other in a separate metal casing of the same area and of
suitable length. This casing which might conveniently contain about three hundred

page_text: stamps, is then closed at one end by a pasteboard or other suitable plug, its other end
being closed by means of a metal cap, a weighted follower having been previously
placed upon the pile of packages and it is then placed in the machine, and the
pasteboard plug removed.
I will now describe the mechanism by the aid of which I deliver a single stamp
from a pile arranged as above stated, and also the means I employ in carrying out the
second part of my invention.
I place the mechanism by preference in a metal box of any suitable size and if
desired so formed and arranged that it may be bolted to a pillar letter box.
In the front portion of this box I form or arrange a receptacle or guides into which
the casing containing the cut packages of postage stamps before described may be
inserted.
Immediately below this, or at the lower end of the before mentioned casing, I form
a horizontal slot in the outer wall of the box, of proper size to allow of the free passage
of one of the card packages containing a postage stamp and level with the lower-side
of this slot I arrange on the inside of the box a table upon which each package
containing a stamp rests before it is pushed out as will be described.
In order to push a package of the pile out through this slot I employ a pusher
which is at one end of less thickness than the package and I give the necessary to and
fro motions to this pusher by means of a lever or combination of levers, or they might
be cams, which upon being moved by the hand through suitable connections extending
to the outside of the box give a forward movement to the pusher so as to push out a
package containing a stamp, and it is then returned to the normal position preferably
by means of a spring or weight.
The said pusher is prevented moving forward until the proper coin is dropped into
a slot in the box, by means of a latch or bolt normally held in engagement with some
part of the pusher by a spring or weight but capable of being withdrawn at the times
desired as hereinafter described.
In the top of the box or it might be at the side thereof I form a slot of a size
suitable to admit of the insertion of the coin.
Within the box at the upper part thereof I mount horizontally in bearings with
capability of revolving a cylinder through which is formed a slot of a size to admit
of the passage of the coin. This cylinder is at the desired times caused to revolve on
its axis sufficiently to change the position and alignment of its slot with the slot in
the box and thereby close such slot but it is normally held with its slot in alignment
with the slot of the box by means of a spring or otherwise.
Beneath the cylinder I arrange a kind of hopper through which the coin passes and
at one side of this hopper I pivot a grooved har in such a manner that by the aid of a
spring it will normally obstruct the passage of the coin. To this bar I connect one
pole of an electric battery whilst to the other side of the hopper or some part carried
thereby I connect the other pole of the battery, such battery being located in the back
or other convenient part of the box.
On the axis of the slotted cylinder at each end thereof I fix an arm or lever. One
arm or lever is connected either directly or through suitable intermediate connections
with an armature of an electro-magnet which is in turn connected with the battery
before mentioned. The other arm or lever is connected in the same manner with the
latch or bolt which prevents the forward movement of the pusher acting upon the
stamp packages so that the rotary motion of the slotted cylinder controls the release
of the pusher.
The grooved bar which obstructs the passage of the coin through the hopper after
it has passed through the slot of the cylinder I by means of suitable connections
connect with the pusher in such manner that when the pusher is moved the the
"grooved bar will be withdrawn from the coin and allow it to pass into the money
compartment below.
In carrying out the third part of my invention I insert in the slot through which
the stamps are pushed out, two or more small springs or spring teeth so arranged that
-they will in no way interfere with the proper outward movement of the stamp

page_text: machine and divide upon the lines of perforations of the stamps into twelve
packages such as that represented at Figures 5 & 6 each containing a perfect postage
stamp.
In lieu of forming each envelope the exact size of a postage stamp as hereinbefore
shown and described I may by increasing the width of the sheet of carlboard 1 form
each finished envelope longer than its contained stamp and thereby afford more space
for advertising upon such envelopes or wrappers as will be readily understood.
I will now proceed to describe the machinery or apparatus I employ for storing and
delivering postage stamps in accordance with the second part of my invention.
a represents a box or case which upon one side thereof is shaped to the contour of a
pillar letter box and is formed with lugs a¹ by means of which it may be bolted
thereto or it might be otherwise shaped and embedded in a wall or mounted upon a
standard.
In the front part of the box or case a is formed or arranged a tubular reservoir or
receptacle or guides might be employed in lieu thereof into or between which a
casing c containing the cut packages c* of postage stamps before described may
be inserted from the front or it might be the upper part of the reservoir or
receptacle b.
The casing c in its interior is formed of about the same area as the cut packages
which are each assumed to be approximately of the same size as a postage stamp and
the cut packages c* are collected and piled one upon the other in such casing c
previous to placing the same in the machine.
This casing c which might conveniently be of a length to contain about three
hundred packages of stamps is then closed at one end by a pasteboard or other suitable
plug c a weight or follower c³ is then placed upon the pile of packages c* and the
upper end of the casing c is closed by means of a metal cap c³ after which the casing c
is placed in the receptacle 6 of the machine when its lower edge will rest upon
ledges a* so as to leave the thickness of the pasteboard plug c or a stamp package c*
beneath the lower end thereof and the pasteboard plug is removed by applying
pressure to the follower c thus forcing the plug c out of the casing c and operating
the machine as hereinafter described when the plug c¹ will be delivered from the
machine leaving the packages c* of stamps in position for delivery.
At the lower end of the reservoir or receptacle b and upon the inside of the
box a I arrange a table b¹ upon which the pile of packages c* rests and upon a level
with such table 6' in the outer wall of the box or case a I form a horizontal slot a³ of
a size to allow of the free passage of one of the card packages c* containing a
postage stamp.
In order to push one package c* of the pile out through the slot a³ I employ a
pusher d which is at its forward end of less thickness than the package c* and 1 give
the necessary to and fro motions to the pusher d by means of a bell crank lever d².
This bell crank lever dis mounted upon a centre of motion d³ carried by a
standard d' and the inner end of such lever is pin-jointed to one end of a link d¹ the
other end of which is pin-jointed to the pusher d whilst the outer end of the delivery
lever passes through a vertical slot a³ (closed by a sliding cover d) in the outer
wall of the case a to the outside thereof where it is spread out or enlarged so as to
afford a convenient surface or thumb-piece d³ by means of which that end of the
lever may be depressed when it is desired to move forward the pusher d and eject
a package c through the horizontal slot a²; the parts being returned to their normal
position by means of a spring d or it might be a weight acting to retract the
pusher d.
The parts are so arranged that the package c* will be left projecting from the
• slot a³ in the manner shown by the dotted lines in Figure 7. but in order to receive
the package c* in case it should be accidentally carried out of the slot a* or when
employing the modified form of pusher d hereinafter described I arrange a small
table a beneath the horizontal slot a³ upon the outside of the case a.
The pusher d is prevented moving forward until the proper coin is inserted in the
⚫ usual coin slot hereinafter more fully referred to by means of a latch or bolte which

page_text: is formed with an inclined face to engage ratchet teeth d³ formed upon the pusher d
and normally held in engagement therewith by means of a spring e* which at one
end bears upon the latch or bolt e and at the other end takes an abutment against the
bracket a*.
The latch or bolt e at its upper end is forked to receive one end of a rod or link e
and it is formed with vertical slots e' to receive the ends of a cross pin e fixed to the
rod or link e².
By these means the latch or bolt e is rendered capable of slight vertical movement
independently of the rod or link e thus permitting such latch or bolt to freely rise
and fall with the ratchet teeth in the return motion of the pusher d without meeting
with any resistance from the rod or link whilst at the same time the latch or bolt e
is capable of being withdrawn from the ratchet teeth in order to release the
pusher dat the times desired as hereinafter more fully described.
In the top of the box or case a or it might be at the side thereof or in other
suitable position I form a slot as of a size suitable to admit of the insertion of the
predetermined coin and I cover this slot with a hood a' as a protection against
rain.
Within the box or case a at the upper part thereof and beneath the money slot a
I mount horizontally in bearings with capability of revolving a cylinder f
through which is formed a slot falso of a size to admit of the passage therethrough
of the coin.
This cylinder is at the times desired caused to revolve on its axis sufficiently to
change the position and alignment of its slot 1 with relation to the money slot a in
the box or case a and thereby close such slot a but it is normally held in alignment
with the money slot at of the box or case a by means of a spring or it might be by
a weight assisted by the spring e* of the latch or bolt e.
1
Beneath the cylinder fl arrange a kind of hopper 9 into and through which the
coin passes from the slot of the cylinder and at one side of this hopper I mount
upon a centre of motion g³ carried by an insulating piece g* a grooved bar g' in such
manner that it will form an inclined side to the hopper 9 and normally obstruct the
passage of the coin.
The grooved bar g¹ is provided with a tail-piece or offset 93 which is by pin joint
connected with one end of a link the other end of which is by pin joint connected
with the delivery lever so that the downward movement of the delivery lever will
be caused to turn the grooved bar g' on its axis g and permit the coin x to pass into
the money shoot h by which it is conducted to the money drawer h¹.
The grooved bar g¹ is normally held in position to obstruct the passage of the coin
by the action of the pusher spring d'aided by a spring g' acting upon the tail piece
or offset g of the grooved bar and the exact position of such grooved bar glis
determined by a stop g carried by the insulating piece 9* at the back of the
hopper g.
This grooved bar g' which is formed of metal and is a contact piece is by a
conductor connected with a terminal which is by a conductor connected with
one pole of an electric battery ; whilst the other side g' of the hopper 9 which
together with part of the back is also formed of metal and is a contact piece is by a
conductor connected with an electro-maguet k which is by a conductor connected
with a terminal which is in turn by a conductor k connected with the opposite
pole of the electric-battery ; so that the introduction of a coin into the hopper
will complete the electric circuit.
The hopper g and connected parts are carefully insulated from electrical connection
with the inechanism or case a.
Above the electro magnet k is an armature which is carried by a lever which
at one end is by a hinge connected to the case a and at the other end by a link
is connected to an arm or lever f³ fixed upon one end of the cylinder f so that when
the armature is attracted by the magnet & the cylinder will be partially rotated
the parts being returned to their normal position upon the breaking of the electric
circuit by means of a spring or it might be by a weight.

page_text: Upon the other end of the cylinder fis fixed an arm or lever f to which is pin
jointed the upper end of the rod or link e² connected with the latch or bolt e so that
when the cylinder f is partially revolved by the magnet kas herein before described
the latch or bolt e will be raised clear of the teeth of the pusher d and the delivery
lever and pusher d may be operated; the revolution of the cylinder thus:
controllng the action of the pusher d.
In the modification represented at Figures 11 to 14 the casing c is formed with a
vertical slot therein and the weighted follower c2 is provided with a projection c
which travels in said slot and after the delivery of the last package c* from the machine
acts upon a trigger lever m in order to bring the "empty" indicator m³ over the
money slot aº.
The trigger lever m which is mounted upon a centre of motion m¹ is normally
sprung upwards by means of a spring m² and is formed with a catch or detent m³ which
engages a projection m* upon the lower end of a rod or link m which at its upper
end is pin jointed to an offset m' from the "empty" indicator m³ which is mounted
upon a centre of motion m³ and is acted upon by a spring m.
"
empty
"
By these moans when the last package c is delivered the projection of the
weighted follower will act upon the trigger lever m and disengage the detent m*
from the projection m* permitting the spring m⁰ to act and move the
indicator m³ over the money slot a®.
In carrying into effect the third part of my invention and in order to prevent the
frandulent abstraction of stamp packages c* by an instrument inserted in the horizontal
slot a³ I arrange in such slot several small steel springs or spring teeth n which are
normally sprung upward into the position shown at Figure 11 so that the issuing
stamp packages c* passing along the upper side thereof will readily depress the same
and meet with no obstruction therefrom whilst at the same time the abstraction of
stamp packages c* by means of an instrument inserted from the outside of the machine
will be prevented.
With the modified form of pusher represented at Figures 17 and 18 the protective
teeth n are unnecessary.
In this case a surrounded opening d* is formed in the pusher d to receive the
stamp packages c* and in the outward movement of the pusher d such packages are
thereby carried to the outside of the case a where they fall upon the table a' and the
pusher d is also provided with a flange d** upon the front edge thereof which when
the pusher d is in its retracted or normal position covers the slot a² and prevents the
insertion of any instrument from the outside of the case a.
The traverse required to be given to this form of pusher being somewhat greater
than that required for the first described arrangement it will be necessary to proportion
the parts accordingly.
In carrying into effect the fourth part of my invention and in order to cause an
audible indication to be given when the electric circuit is completed by the insertion
of a coin or a coin attached to a string or other means I place in the electric circuit a
bell o which will ring and continue to ring until the coin if properly inserted falls
through to the money compartment 4' or if the coin be attached to a string or other
means, until it is removed by an authorised person having access to the machine.
The modified form of casing c represented at Figures 11, 13, 19, and 20 is formed
with a closed top c³ and is intended to be permanently fixed in position in the machine
and charged with stamp packages c* through an opening a formed in the front wall
of the case a for that purpose and closed by means of a door a³.
In order to enable the casing c to be charged whilst it is fixed in position I form a
broad slot ce in the upper part thereof through which the stamp packages c* may be
introduced into the casing c and 1 extend a narrower continuation c³ of such slot to or
nearly to the bottom of the casing c in order that the stamp packages may be seen and
manipulated and properly arranged in position.
Openings closed by doors a¹º, a" are formed in the walls of the case a in order to
afford access to the battery and mechanism.
I will now describe the operation of the machine.

page_text: If a coin be inserted in the money slot a in the case a: it will pass through the
slot of the cylinder finto the hopper 9 and will be obstructed in its passage by the.
grooved bar g'.
Here it will close the electric circuit, in which is placed the electro magnet k, with
the result that the armature and lever will be drawn down and will through the
link and lever f turn the cylinder f upon its axis and thereby close the money
slot a of the case a as its slot f¹ will be moved out of alignment therewith and the
cylinder will therefore present a solid surface thereto.
The movement of the cylinder f upon its axis will cause the lever f' through the-
link to withdraw the latch or bolt e from the teeth of the pusher d so that when
the delivery lever d³ is depressed the pusher d will push one of the stamp packages. c*.
out through the slot a².
At the same time the grooved bar g' will through its connection by the link g* with
the delivery lever d² be turned upon its centre of motion 9 and permit the coin z. to
full into the money compartment h¹ thereby breaking the electric circuit and causing
the cylinder to resume its normal position and at the same time lower the latch or
bolt e into position to again engage the. teeth of the pusher d and thus lock the:
delivery mechanism until another coin is inserted in the money, slot aⓇ.
It will thus be seen that the rotary movement of the cylinder controls the release
of the delivery mechanism and it therefore follows.that.if a coin attached to a length
of string or wire or any other such device be inserted into the money slot a³ so as
to complete the electric circuit in the hopper g such string wire or other means:
passing through the slot f¹ of the cylinder will prevent the rotation thereof. so that
the latch or bolt e will not be withdrawn. from, the teeth d of the pusher d and the
delivery mechanism will still remain locked.
I may also if desired, employ a counter in connection with some moving part of
the apparatus, in order to record the number of stamps delivered from the machine.
It will be evident that these improvements with the exception of those parts which
are described with-respect-to-Figures 1 to 6 may be employed to deliver goods other
than postage stamps.
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 method of preparing or protecting postage stamps for automatic delivery
consisting in placing a row of stamps upon a sheet of cardboard or other suitable
material and folding over parts thereof to form a long envelope or package and
afterwards dividing the same upon the lines of perforations of the stamps, substan-
tially as herein shewn and described with respect to Figures 1 to 6.
2. The method of preparing or protecting postage stamps for automatic delivery
consisting in enclosing a stamp in an open sided envelope or case formed of several
folds of cardboard or other suitable material substantially as herein shown and
described.
3. The general arrangement and combination of parts constituting an automatic
delivery machine substantially as herein shown and described with respect to
Figures 7 to 10.
4. In a coin-freed or automatic delivery machine a slotted cylinder mounted with
capability of revolving in bearings and normally held with its slot in alignment with
the path traversed by the coin and so connected with a latch or bolt controlling the
delivery mechanism and with the armature of an electro magnet that upon the
armature being attracted by the magnet the cylinder will be partially revolved and
the latch or bolt withdrawn, substantially as hereiu shewn and described and for the
purpose stated.
5. In a coin-freed or automatic delivery machine a slotted cylinder mounted with
capability of revolving in bearings and normally held with its slot in alignment with
the path traversed by the coin such cylinder having fixed upon each end thereof a
lever one of such levers being connected with a latch or bolt engaging teeth of the
R

page_text: pusher and the other of such levers being connected with the armature of an electro
magnet so that upon the armature being attracted by the magnet the cylinder will be
partially revolved and the latch or bolt withdrawn from engagement with the pusher,
substantially as herein shewn and described and for the purpose stated.
6. In a coin-freed or automatic delivery machine in combination, an electric
battery, an electro magnet and armature, a slotted cylinder mounted with capability
of revolving in bearings and normally held with its slot in alignment with the path
traversed by the coin and so connected with a latch or bolt controlling the delivery
mechanism and with the armature of the electro magnet that upon the armature
being attracted by the magnet the cylinder will be partially revolved and the latch or
bolt withdrawn; and an insulated hopper one side of which is fixed and forms a
contact piece connected with one pole of the electric battery and the other side of
which is moveable and forms a contact piece connected with the opposite pole of the
battery such moveable side being arranged normally to obstruct the passage of a
coin through the hopper and thus complete the electric circuit causing the electro
magnet to revolve the cylinder and withdraw the latch or bolt whilst such moveable
side is so connected with the delivery mechanism that upon the movement thereof the
coin will be released and permitted to fall into the money compartment thus breaking
the electric circuit and causing the parts to be restored to their normal position,
substantially as herein shewn and described and for the purpose stated.
7. In a coin-freed or automatic delivery machine two or more independent spring
teeth located in the delivery slot and so arranged that they will not offer any
obstruction to the passage of the goods but will prevent the fraudulent obstruction
thereof, substantially as herein shown and described.
