Improvements in Coin-freed Apparatus.
I, CHARLES A. KAICHEN, of 168 Guswald Street Detroit, Wayne Co.,
Michigan, United States of America, Broker, 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:-
My invention relates to automatic selling devices, and to machines of that class
that are controlled by a coin and in which counterfeit coins are detected and
separated. The object is to provide a machine that will deliver a package only
when the price of the package in good coin has been deposited. The necessary
elements of such a machine are, means for extracting a single package, means for
locking the device to prevent the extraction of a package until the proper coin is
deposited, means for unlocking the device when the proper coin is deposited, and
means for extracting or diverting counterfeit or spurious coin from the unlocking
mechanism. I will describe these several elements separately, and indicate their
relation and operation.
Figure 1 is a vertical sectional view.
Figure 2 is a vertical sectional view showing the elements in a different position,
and at a different stage of the operation.
Figure 3 is a vertical section showing the manner of ejecting the packages.
Figure 4 is a view from the rear of the mechanism.
Figure 5 is a detailed view of the detecting device.
Figure 6 is a view of the plate separating the packages.
The whole device is contained in the cabinet shown in Figure 1. I will first
describe the coin-detecting device.
In the drawings, A is the wall of the cabinet, within which the mechanism of
my device is assembled. A is the metal frame attached to the wall and on which
is supported a scale consisting of the balance B and the chute C. The balance B
is mounted on trunnions b, these trunnions being turned to a point, and if desired
mounted in jewelled bearings on the ends of the set screws is the weight of
the balance and is made adjustable on its end. is a step-bearing, which may also
be jewelled. This bearing supports the chute C. This chute is made so as to
accommodate the coin to be used, and preferably carries the coin in one direction,
and then turns it and leads it in the opposite direction. This construction requires
the coin to be retained within the chute a sufficient time to weigh it. The chute is
supported on the strap c in which is mounted the steel pin c'. The strap c is
engaged at the lower end with the pin which has a bearing in the frame A¹ and
guides the chute in a vertica! line. This portion is also provided with the horizontal
pin which traverses an incline & in the frame A'. This causes the chute to
swing when it is depressed by the weight of a coin and determines the position that
the chute will be in when weighted with any proper coin. From the foregoing
description it is seen that, when a coin is placed in the chute, the chute drops, if
the coin is of sufficient weight to overcome the balance, and as it drops, swings.
If the coin or other article placed in the chute is not of sufficient weight to over-
come the balance, it will traverse the chute and be delivered from the end C' of the
chute at a different point than if it were of sufficient weight to overcome the balance
and swing the chute.
B' is a chute extending to the outside of the case, and in which the coin is
originally deposited and from which it is delivered to the chute C.

page_text: The chute C is designed to deliver a coin in two compartments of the machine,
one compartment where the coin is too light to overcome the balance, and the other
compartment when the coin is of sufficient weight to overcome the balance, that is,
of the weight of the coin designed to be used, or of greater weight. Coins or discs
of greater size than the one designed to be used are excluded from the machine by
making the opening through which the coin is first passed of just the size of the
proper coin. From the foregoing it is seen that all coins lighter than the requisite
coin are deposited in the first compartment, which preferably conducts the coin
or disc to the outside and indicates to the party inserting it that it is not
sufficient.
If the coin or disc inserted is of sufficient weight to operate the balance, the
chute C swings and drops the coin into the passage D. Such disc or coin may be
of lead or of iron, the two metals named representing two classes, each of which
must be thrown out by the device. This is accomplished by combining a magnet
and an anvil, the magnet to control the movement of the disce or coin through the
chute or passage and the anvil to distinguish between the two discs or coins by the
disinnce which each will rebound. E is a small horse-shoe magnet with the poles
on the plane of the wall of the passage D so that a coin or disc passing through
will be attracted by the magnet. Lead, silver or nickel will pass the magnet
without having its momentum affected, but iron will be held by the magnet and will
drop slowly through the passage. F is the anvil placed at the lower end of the
passage upon which all dises or coins must drop after passing the magnet. Silver.
aickel or lead will strike this anvil as if there were no magnet in the passage, the
nickel or silver will rebound a sufficient distance to drop into the chute F, the lead
will rebound a less distance and will drop into the chute F. The iron, owing to
the attraction of the magnet, will slip slowly down the passage and will strike the
anvil with much less force than the other metal and will consequently rebound only
a sufficient distance to enter the chute P. Thus it is seen that the device will
throw out lend and iron, and will carry forward to the mechanism to be hereinafter
described, silver or nickel.
I will now describe the means for storing the articles to be sold, the means for
extracting the same, and the coin operated unlocking mechanism whereby the
device may be operated on the insertion of the proper coin. G is a rectangular
receptacle pivoted on the hinges g whereby an oscillating movement may be secured.
This receptacle has a slotted opening G'in the back, and is open at the bottom.
The walls in the front do not extend to the bottom, but leave a space g' sufficient
to allow a single package to be forced out and from underneath the remaining
packages in the box, the walls of the receptacle holding those above the
lower one.
The edges of the slotted opening G' are rolled, forming a round bearing for the
tin separating plates R. These separating plates lie between the packages G'.
These packages may be envelopes if the machine is used as a stamp-selling device,
or they may be packets of confectionery, tobacco, etc. S, is a false bottom
supporting the vertical strip s. , is n vertical plunger mounted in suitable guides
on the strip s. This plunger is held to the upper extremity of its movement by
the spring, and it reaches high enough to catch the lowest package and draw it
from the receptacle in the manner shown in Figure 3., As the receptacle G, is
swung to the front, the plunger springs up back of the package in position to eject
it. is an adjustable front to the receptacle (i, whereby the opening at the
bottom may be made a suitable width to fit any package.
The receptacle G, when in its forward position is locked. H, is a piece ntinched
to the frame and is provided with a channel through which the coin N, máy pass.
K, is a combined chute and detent pivoted to the receptacle G, which engages at
its inner end with a notch, in the piece II, and while so engaged prevents the
receptacle from swinging. The proper coin for operating the device having been
delivered to the passage P, by the detecting devices before described, drops into
the chute K, and folls into the channel in the piece EI, and lodges in the position

page_text: shown at N, and is prevented from passing through by the chute K. The coin
now serves as a key for unlocking the device, for if the receptacle be forced back-
ward, the detent or chute K, is lifted out of engagement by the coin which rolls
under it until the coin is free to drop under the chute and roll through the
passage II', to the box H2. The receptacle can now be swung backward until it
delivers a package in a manner before described.
operate the receptacle by means of the crank Q. This crank operates a shaft
that extends through the machine and which carries the arm M. This arm as it
rotates comes in contact with the pin K', and forces the receptacle backward until
the arm passes the pin, when the receptacle is free to swing back. To prevent the
receptacle from swinging back before it has completed its full movement, I provide
the arm M, with a ratchet M', with which the detent L, engages as soon as the
rotation of the arm commences. The ratchet M', is provided with means for
engaging with the detent so as to prevent the turning of the handle in either
direction while the receptacle is swinging back. When the receptacle swings
forward again to its limit, it comes in contact with the arm L, and raises the
detent, when the second half of the revolution of the handle can be made.
The package, when delivered from the receptacle G, slides to the outside of the
case over the incline II.
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. The combination of the weighing scale, the magnet, the anvil and the
unlocking device, consisting of the chute Kand the portion H, substantially as
described.
2. The unlocking device, consisting of the chute K, and the portion H,
substantially as described.
3. The improved apparatus constructed substantially as described with reference
to the accompanying drawings and operating as and for the purposes, specified.
