Description

Are self-sellers for various waxes

known. Solutions have been proposed in which, after a certain Number of purchases besides the desired goods also money is returned.

It is also known to provide different slots for the different coins and to effect the setting for the desired goods on a circular board. Furthermore is already

ίο previously suggested the issue coins to be accommodated in vertical tubes. Even those self-sellers where one Output device provided for residual amounts are known.

The present invention makes use of such previously known arrangements. she but is characterized in that with self-sellers for different goods with a Remaining funds dispenser through the remainder dispenser after at the self-seller the paid amount and the price of the selected goods are set, the the respective remaining amount is issued automatically.

Fig. Χ, ι a and 2 show schematically an elevation and a side elevation: of the first embodiment.
Fig. 3 to 9 are individual views.

Fig. 10 is a schematic view of the second embodiment.

Figs. 11 to 17 are detailed views.

The first embodiment has a purchase item selector, a coin amount counter, a remainder determiner and a remainder dispenser, which are described one after the other.

The object of purchase selector is used to allow the buyer to make a choice among the various purchase objects that the self-seller can issue. It has a number of contacts A (Fig. 1, ia and 2), which are arranged in a circle on a disk α and each correspond to one of the objects of purchase; each contact is insulated from the disk a and the other and is connected to a +5 insulated conductor 2, 6, which leads to the electrically operated dispenser for the object of purchase. In Fig. Ia only the conductors 2 and 6 corresponding to the contact A ₂ or A _{e are illustrated.}

A conductive insulated ring is provided on the disk B α within the contact range A, the existing with each contact A by a a rotatable arm b with contacts D, C contact bridge can be connected; the arm δ sits firmly on one

36216?

Shaft δ ₂ , which is mounted in the fixed wall c of the self-seller, extends through the same and carries a snap crank on the outside, which can be turned away by the buyer via a series of snap holes, such as a _x. If the snap spring b _{3 is} now in one of the holes, the contact C of the arm b rests on the corresponding contact A ₁ and the self-seller is set to hand over the relevant object of purchase.

The coin counter has a rotatable,

disc placed outside wall d (Fig. i) of the self-seller's box & (see also

'Fig. 9), in which just as many money straps are provided can be deposited as types of money.

So here are money slots e _x z. B. for 0.05, 0.10, 0.20, 0.50, i, -, 2, - Fr. In the wall d an equal number of slots g are now cut out, each corresponding to the one slot of the disc and open into a channel ^ _1. The disc e can be turned by a snap crank and then fixed by the pin h so that the slots e _x come to lie in front of the coin openings g belonging to S5, so that the buyer can insert the coin in question into the self-seller. The size of the required rotational movement of the disc e is therefore a measure of the value of the coin inserted. This goes through the usual known Münzprüf devices, which are not shown here, and finally gets between two contacts F, G; one (F) is stationary and is connected by a line 9 via the line 7 to the network which feeds the switch. The other contact G is attached to a rotatable arm and connected by a line χτ to one terminal of an electric motor M _x . The two contacts F, G in the ready position form a wedge-shaped tapering channel in which the coin is caught and thereby closes the circuit of the motor M _x , the other terminal of which is connected to the second power line 8. The movable one ^! Contact G is mechanically connected to a linkage k , which can be operated in such a way that; the slot formed by F and G enlarges and thereby allows the coin to fall into a cash register 12.

The starting of the motor M _x (Fig. 1) caused by the coin is now used to determine the value of this coin. For this purpose there is a slide χ '■ which is guided on two parallel, vertical rods bb (see also Fig. 2) by means of clamps aa , mainly made of sheet metal. exists and is moved by the motor M _x by an amount corresponding to the given value. On one side is the sledge * ? provided with a triangular toothing w , ₍ in which a tow pawl fi can engage, which at f _x (see also Fig. 3) is rotatably mounted on a slider 0. The tow pawl -p is under the action of a spring fi ₂ , which seeks to remove it from the toothing w, but is firmly connected to an arm r which can be acted upon so that it comes into engagement with the toothing w . The slider 0 is guided on two rods s parallel to the rods bb and can range from a solid, a zero position indicating stop and removed, and then be brought into contact again with j this. the first movement is caused by the buyer and is the larger the value of the coin, the larger. for this purpose, the shaft I the disc & by a conical gear-I gear I _2, a shaft I _x, a second conical \ gear transmission I ₃ with a cylindrical j gear Z _{4 are} connected, that is with a Zahni rod t is engaged. the rack t] with a slide that can be moved on rod s ; taker m, on which the slider 0 can rest, connected.

, The started motor M _x operated by means of. a transmission m _x a spur gear m ₂ , which is in engagement with a rack υ ^{and 1 is} firmly connected to a ' driver η guided on the right rod s _2. The sense of rotation! of the motor M _x is chosen so that the driver η moves from bottom to top in Fig. 1 \ , comes into contact with the slider 0 and pushes it forward until this slider again touches the stop u . In doing so, however, the part n _{x of} the driver η strikes the arm r, so that the pawl φ comes into engagement with the toothing w and the carriage χ has to join in this movement from bottom to top. .

The slider 0 is provided with a stop q by means of which it actuates the linkage k in such a way that, when 0 arrives again in its zero position, the arm i is removed from the contact G and the inserted coin is released so that it can be placed in the cash register 12 falls into it.

The slide χ forms the contact device mentioned in the introduction and is provided for this purpose on its rear side with three contacts M, N, M (Fig. 1), which are arranged on the same line perpendicular to the guide rods bb.

The middle contact N is in any position of the carriage χ with a contact strip P in contact. In contrast, the lateral contacts M come into contact alternately with the contacts O of two sets of contacts. In both sets, the contacts O are equidistant from one another. The contacts of one set are each in the middle of two consecutive contacts of the other set. Each contact O is assigned a price

number denotes, namely those of the sentence on the left z. B. with the numbers 5, 15, 25, 35 ... to 245, those of the set on the right with the numbers 10, 20, 30 ... to 250. The distance of the consecutive contacts 5, 10, 20, 25 is - equal to the pitch of the toothing w.

If the slide x, starting from the zero position shown in full lines in Fig. 1, moves from the bottom to the top, the contacts M, N, M come to the xo. The height of the contact O which corresponds to the value of the coin inserted, whereby this value is determined.

Each contact O is connected by a line 21 (Fig. Ia), of which only one is indicated in the drawing, with one of the contacts A of the disk α , which corresponds to an object of purchase of the corresponding purchase value. Since it is assumed that the contacts A ₂ , A ₈ correspond to objects of sale that are worth the same purchase worth 0.65 Fr., the two are connected by conductors 2 and 6 to a busbar E , from which the conductor 21 extends. In the conductors 2, -6 electromagnetic devices are switched on, which are not indicated in the drawing and are used to actuate the output devices for the objects in question.

The driver η is returned to the rest position illustrated in Fig. 1 by a weight cord roller drive.

For the remainder, if the leaves

Driver η is returned to its rest position, also its part% the arm r, so that the drag pawl ft releases the slide χ , which tries to go down under the action of its own weight, but by a spring under the action of a spring, not shown Locking pawl gg (Fig. I, 4 and 5) is prevented, which can come into engagement with a toothing d din provided in its right-hand edge. The pawl gg only releases the slide χ to the extent that the remaining output takes place.

The remainder can be issued in 0.05 or 0.10 franc pieces, as desired.

The remainder dispenser therefore has two vertical tubes hh and ii (Fig. 1, 5, 6, 7 and 8), which are arranged next to one another and in each of which there are coins of one type stacked on top of one another, in hh 0.05 and in ii ο, ΐο Frank pieces. At the bottom of each tube is as shown in Figures 6-8 for tube ii ; first a fixed plate in which a circular opening uu the diameter of the coin in question is cut out, then the lid of a downwardly open rotatable sleeve qq, in which an elongated opening is provided, the width of which is large enough to receive a coin and its Height is equal to the thickness of this coin, finally a fixed, downwardly open box ss, in the lid of which an opening r _x r _{x is} cut (Fig. 8), the dimensions of which correspond approximately to those of the opening rr , but are offset from it. The sleeve qq can be given a rotating movement in the course of which the opening rr comes to lie under the opening # «, picks up a single coin and takes it with it until it partially coincides with the opening r _x r _x. Then the coin falls through the opening r _x r _x and arrives in an output channel υ ν. The rifle s r rests

^! a fixed support tt. A similar device is provided for the tube hh . Both channels υ υ unite below

^: a single.

For rotation of the two tubes II and hh associated bushings a special common electric motor M ₂ is provided (Fig. 1) which _s m by means of a transmission, a rotating and axially displaceable shaft 11 (s. Also Fig. 7) drives. The latter can be moved by the buyer to the left or to the right with the aid of a control lever kk , starting from a central rest position. If it is shifted to the right, a pin 0 0 of this shaft 11 takes a loose pulley η η with it in the rotation of the latter and this moves a second pulley M ₇ , a worm ft ft and the thick-toothed sleeve qq der _{by means of a driving thread M 6} Tube ii in rotation.

If the buyer moves the shaft 11 to the left, another pin connects a second loose pulley to drive this shaft and the sleeve qq of the other tube hh .

On the shaft 11 sits a roller W ₁ (Fig. 1) made of insulating material, which is moved with it to the right or left and then presses one or the other of two contact springs Z ₁ X ₁ against contact springs AA and y _x to the To close the circuit of the motor M _2. For this purpose, the contact springs AA and y _{x are} connected to the power line 7 by a line 14. The contact springs z, X ₁ can be brought into connection by lines 16, 17 with one terminal of the motor M ₂ , the other terminal of which is connected to the power line 8. The line 16 is in constant connection at r _x (Fig. 8 a) with a contact arm R, which can touch a fixed contact T; this is permanently connected by a line 18 to a fixed contact J ₁ , which can be connected by a contact bridge JH to a contact H ₁ from which the line 17 extends. In the zero position of the slide χ the contact arm R is from the contact T by a stop cc this

Slide lifted off. On the other hand, the contact bridge JH is carried by the rack υ and this connects the contacts J ₁ , H ₁ only when ν is also in the rest position. It follows that the motor M ₂ can only turn when the slide χ is no longer in the zero position and the rack υ is in the rest position.

The rotating sleeve of the tube hh (Fig. I) ίο is provided on the outside with a strip ww which, when the sleeve is rotated, comes into contact with a roller x _z carried by an angle lever χ χ (Fig. 4) and thus the angle lever χ χ, which sits loosely on a shaft ff, comes to a stop. On this shaft ff the pawl gg is loosely arranged, which is then made to swing out by means of a shoulder yy on the arm of the lever χ χ and immediately releases the toothing dd so that the slide χ immediately moves down under the action of its own weight . This arm of the lever χ χ is also equipped with a pawl ζ ζ which engages in the toothing dd; the interrelated action of the two pawls gg and ζ ζ allows the carriage to move one tooth for each revolution of the liner. Since the pitch of the toothing dd is the same as that of the toothing w, a tooth of dd corresponds to a 5 ct. Piece. The rotatable sleeve qq of the tube ii (Fig. I, 5, 6 and 7) has an outer helical strip α α α, which can be in engagement with a toothing ee , which is provided in a sheet metal Z ₁ attached to the slide χ and the teeth of which are formed at right angles. The strip α α α can act on the pawl gg in such a way that it removes it from the toothing dd. During one rotation of this sleeve, the pawl gg is first pulled out of the toothing dd by the strip aaa and then the slide χ is allowed to fall gradually, since the strip α α α then rotates slowly in the one gap in the toothing e e. If α α α leaves this toothing, the pawl gg comes into engagement with it again and blocks any further movement from χ downwards until further notice. The whole thing is set up in such a way that the carriage χ moves by two teeth of the toothing dd during such a revolution of the sleeve qq.

A line 1 coming from the contact ring B of the contact disk α (Fig.ia and 8 a) is connected to a fixed contact K ₁ , which can be connected to a contact L ₁ by a contact bridge KL . A contact arm Q (Fig. 8 a) come into contact, which at U is in constant contact with the contact strip P (Fig. 1). A second stop cc of the slide χ acts on the contact arm Q in such a way that Q does not touch the contact L ₁ when χ is in its zero position. On the other hand, the contact bridge KL is carried by the toothed rack υ ' . It connects the contacts K ₁ , L _x only in the rest position of this rack. The circuit containing the electromagnetic device for actuating the output device of any object of purchase can only be closed when the slide χ is not in its zero position and: the rack υ is in its rest position.

\ The operation of this Ausführungsbei-ι, game is the following:

'In the rest position the contact b is the object of purchase selector on any of the contacts A and the disc in a loading e' agreed position in which no slit e _x g coincides with a coin opening.

The slider 0 is in contact with the stop u. The driver η and the rack υ are in the position shown in Fig. 1 in full lines. The slide χ is also in the zero position shown in full lines in this figure, in which the contacts M are not in contact with any of the contacts O.

Furthermore, in the rest position, the control lever kk is in the neutral position illustrated, so that the contact springs y _x , AA, X ₁ , ζ do not touch. The motors M ₁ , M ₂ do not rotate because there is no coin between the contacts F, G and 95 'the contact between contact arm R and contact T is therefore canceled.

Someone wants to get a purchase object, which costs 0.65 Fr., he turns the contact b of the purchase object selector so that it turns the contact C of this arm b on the contact A corresponding to this purchase item such. B. on A ₂ .

Now the following cases can arise: Either the buyer pays with a single one One coin too many (case a), or he throws in several coins one after the other represent too high an amount (case b), or he pays in correctly (case c), or he throws too little a (case d).

In case a, it is assumed that the buyer throws in an i-frank coin; it must therefore 0.35 Fr. are issued.

So that he can insert this coin, he must turn the disc e by means of the crank Jp ₁ so that the corresponding slots & coincide with the coin opening g . As a result, the slider 0 is mechanically and inevitably removed from the fixed stop u by an amount that corresponds to twenty teeth of the left toothing w of the carriage χ without it moving, since the tow pawl f

is not yet in engagement with this toothing. As soon as the coin is now _{inserted into the slots ^ 1} and coin opening g , it rolls down the corresponding channel ^ ₁ and comes to stand between the contacts F and G , which hold it in place for the time being. This closes the following circuit: The current runs through the power line 7, the line _/ 9, the contact F, the coin, the ίο contact G, the line ii, the motor M ₁ and through the power line 8 back.

The motor M ₁ is thus started and drives the gear wheel m ₂ , by means of which the toothed rack υ and the driver η are moved from bottom to top. The driver η comes into contact with the slider 0 and with the arm r after having covered a certain distance. As a result, the tow pawl φ is brought into engagement with the toothing w . From now on, the driver n, slider 0 and slide χ move upwards at the same time until the slider 0 hits the stop u , after χ has had twenty teeth on the toothing w and the right 'contact M is on the i-Fränk- Contact from O has come to a standstill. At the end of this stroke, the slider 0 acts on the linkage k and frees the coin from the contacts F, G in such a way that the motor M _{1 is} stopped and the weight y, driver η and rack ν return to their rest position. When the contacts M were led away via that contact O, which corresponds to 0.65 Fr., the following circuit was established:

0.65 Frank contact O, line 21, busbar E, line 2, electromagnetic device (not shown) of the output device, line 2, contact A ₂ and D, contact ring B, line r, contact bridge KL, contact L ₁ , contact arm. Q, contact band P, contacts N and M and 0.65 Frank contact O.

This circuit is interrupted at K ₁ and L ₁ when the rack ν and the slide χ move upwards because the contact bridge KL then no longer connects the contacts K ₁ and L _1. The sliding of the contacts M over the 0.65 Frank contact O does not result in any circuit being closed.

The upward movement of the slide χ has registered the value of the coin inserted.

Now, however, the remaining amount, here 0.35 CHF, has to be surrendered. Let's assume that the buyer wants to receive this remainder in the following composition: 0.10 - + - 0.10 + 0.10 + 0.05 Fr.

To do this, he rotates the lower end of the control lever kk to the right and thus moves the shaft 11 to the left.

As a result, it closes the circuit of the motor UiT ₂ via the power line 7, the line 14, the contact springs y _x , X ₁ , the line 16, the contact arm R, the contact T, the line 18, the contact J ₁ , the contact bridge JH, the contact H ₁ , the conductor 17, the motor M ₂ and the power line 8. Because contact arm R touches contact T, carriage χ is not in its neutral position and contact bridge JH connects contacts J ₁ , H ₁ , because rack ν is back in its rest position.

At the same time, the shaft 11 is coupled: with the sleeve qq of the tube / i.

Thereby, the sleeve is in rotation qq \ offset, on the one hand the release of a, single 0.10-Frank-piece and on the other hand, a; Such movement of the pawl gg and the toothing ee causes the carriage χ to move two teeth of the toothing w, that is, by an amount downwards that corresponds to 0.10 Fr.

The buyer keeps the control lever kk in the given position. The sleeve qq makes two more rotations and, with each rotation, brings a 0.10 franc piece to the table while moving the

■ slide χ down by the corresponding amount.

Now the buyer pushes the lower end go of the control lever kk to the left and thus the shaft II to the right.

As a result, the contact springs ζ and AA come into contact with one another. Because they are like the contact springs X ₁ and y is _x to the lines 16 and 14 are connected, the circuit \ ₂ of the motor M is not interrupted; this rotates! therefore continue. On the other hand, the shaft II j is coupled to the sleeve qq of the tube hh. 'A 0.05-Frank piece comes to the out-I would be, and the slide χ moves by one tooth of the toothing w, i.e. by an amount

■ which corresponds to CHF 0.05, downwards. Characterized the j left contact M comes on those ¹ O contact to stand, corresponding to 0.65 Fr., \ and now includes, as rack and ν Kon-I clock bridge KL in their rest position, are fol-

■ the current circuit:

0.65 Frank contact O, conductor 21, busbar E, conductor 2, not shown electro- ^: magnetic device of the output device, conductor 2, contact A ₂ , contact bridge

■ CD, contact ring B, conductor 1, contact K ₁ , contact bridge KL, contact L ₁ , contact arm Q, contact strip P, contacts N and M ,, 0.65 Frank contacts O.

I As a result, the configuration (not shown) > The delivery device of the purchase item in question is electromagnetically actuated and this handed over to the buyer.

At the same time, by closing this circuit, another, not shown, is created

Electromagnetic device excited, which acts by means of a shaft bbb on the pawl gg so that it releases the slide χ , which is returned to its zero position under the action of its own weight, whereupon the circuit of the motor M _{2 is} interrupted. The switchgear is now ready for another order.

The buyer can just as well throw in the sum of ίο ι Fr. in the following composition (Case b): 0.05 + 0.20 + 0.20 - + - 0.10 Fr.

He has to turn the disk β so that the slot e ¹ . and the coin opening g come to match and then deposit the 0.50 Fr. The carriage # moves up ten teeth of the toothing w and then stops, while the drivers' η and rack ν are brought back to their original rest position by the weight y. Then the buyer brings the disk back into its zero position and then brings the slots e _x , g corresponding to the 0.20 franking coins into alignment; he throws in a 0.20 franc piece, the slide χ rises again, but only by four teeth, while the driver n, rack ν are again returned to their rest position under the action of the weight y. Similar operations are carried out for the second 0.20-franc and the 0.10-franc piece. Finally, contact M of χ is on contact O, which corresponds to 1 Fr., as before. \ Then the rest of the output takes place as described. '

The buyer can only get the rest of it in 0.05-franc pieces; he has: only to set the control lever kk accordingly. 'If the buyer is correct in any-; I throws in a compilation of coins (case c), then finally, as before, the contacts M, N, M come to that contact O , which corresponds to CHF 0.65. As soon as the rack υ and the contact bridge KL have been returned to their rest position, the circuit of the output device in question is closed and the selected object of purchase is made available to the buyer.

If the buyer pays too little for the amount of the selected purchase item (case d), the contacts M, N, M come to that contact O , which corresponds to the paid amount, and remain there,; since no object of purchase is issued. . By operating the control lever kk , the buyer can receive the value of the inserted coin (s) in 0.10-franc and 0.05-franc pieces; but he cannot possibly; the selected object of purchase for issue! bring. If he does not operate the control lever kk , the next buyer will benefit from the amount thrown in, since the slide χ i is no longer in its zero position, but is already j away from the latter.

The rotatable lever b of the object of purchase, selector can also be replaced by a disk. Likewise, the disk α can be provided with several rings consisting of contacts A , depending on the number of the purchased item. The disk e can advantageously be arranged behind the wall d , so that when it is rotated by means of a handle only the; Desired slot e _x in a recess of: Wall <L appears.

• The arrangement according to the second exemplary embodiment (Fig. 10 to 19) differs: from the first mainly in that the! Remainder dispenser has a series of contacts and j several contact ^{pieces that can move towards one} another with the contact row and the contact piece of the coin amount counter. Each contact in the contact series corresponds to a given price level in such a way that the contacts represent a continuous price series. The contact pieces are used to control various money dispensing devices, so that each remaining dispensing takes place in an arrangement of coins determined by the arrangement of these contact pieces.

The purchase item selector has a hollow go cylinder 150 and a rotatable drum 151 (shown broken off in the middle of Fig. 10 a), which are arranged one inside the other and of which Fig. 12 shows a development of the lateral surfaces. The hollow cylinder 150 is fixed and carries three rows of contacts 71, 72, 73 arranged around it and their number in each row are equal to that of those that can be issued by the self-seller Objects is. He also carries three contact rings 74, 75, 76, which are arranged next to the contacts 71, 72, 73. the Drum 151 can rotate about its axis and has three elongated contacts 68, t> 9, 70 equipped, the simultaneous connection of a contact of each contact row 71, 72 or 73 with the corresponding contact ring 74, 75 or 76 in each position of the drum 151 to serve. To rotate it, the latter is keyed on a shaft, not shown, which consists of the self-seller's box protrudes and outside this box with a snap-action crank is provided. To choose an object of purchase, the buyer only has this crank in the appropriate position marked by a label. That brings he contacts 68, 69, 70 simultaneously with contact rings 74, 75, 76 and those contacts from rows 71, 72, 73 that correspond to this object of purchase, so that he prepares various circuits, as will be explained later.

For the sake of simplicity, only two contacts from rows 71, 72, 73 are shown in Fig. Ioa.

Each type of purchase item is contained in a special container, not shown, from which they are dispensed piece by piece. This output is provided by a device actuated by a solenoid, not shown. ίο The arrangement of the coin amount counter is as follows: As mentioned in the introduction, only 0.05, 0.10, 0.20, 0.50 and i-Frank pieces can be deposited. Accordingly, five slots, not shown in Fig. 10, are provided next to one another in the box of the self-seller. Dimensions correspond to those of the coins in question in terms of diameter and thickness. '; Thus, a ^pre-i provisional gross examination of the deposited money is j pieces made in the usual manner. The ball slots Munich j the mutually parallel in five channels I53 to _X '* 53s · ^νση which only two (153 ^ and 1535) in Fig. 10 are shown. They have insulating partitions, e.g. B. made of fiber, and lean with their lower ends against a common drum 158, which is also made of insulating material. Metal strips O ₁ to 6 _{S are} provided at these lower ends, which are supported by the thrown coins such as 159, 160 on the outer surface of the cylinder 158 arranged contact _{rings 15S 1} to 158g are brought into electrical connection. The metal strips 6 _X to 6 ₅ are now connected by a common line 173 to a contact 101 (Fig. 10 a) of a switch S ₁ , 1 of which another contact 100 is connected to a solenoid M ₁ , the other- i is connected to the various contact rings 15S ₁ to 1585 by a common line 174. By throwing in a coin, if the bridge 99 of the switch S ₁ connects the contacts 101, 100, the circuit of the solenoid M _{1 is} closed, which switches on the drive motor M _{0 of} the self-seller. For this purpose, the solenoid core, not shown, which is held in a rest position by its own weight, is sucked in by the solenoid M ₁ from bottom to top and acts by means of a rod i6r on one arm of a lever 162, the other arm of which on one of the Shaft of a switch S ₂ wedged arm 164 can act. The * on the shaft of switch S ₂ stuck Kontaktbrückei65 is thereby brought from the zero position, which is characterized by 0-0 , in the position F-F, which corresponds to the rotation of the motor M ₀ , in a direction opposite to the rotation of the clockwise j and is referred to here as the forward sense. The motor M ₀ switched on in this way now drives the shaft i66 of the cylinder 158.

Each of the rings 15S _1-1585 is interrupted by an opening provided in the cylinder 158 recess 158g to I58 _1O, in which the deposited money corresponding piece may fall 159 or 160, to be then carried along in the drum rotation, and the channels below the lower wall of the respective I53 _X to 1535 too. hike. It actuates a lever, such as 167 !, which closes one of the switches 16S ₁ to i68 ₅ ; the switch now controls the circuit 1Og ₁ , 17O ₁ or 1695, 17Ο5 of a solenoid m _t or m ₂ , m ₃ , W ₄ , W ₅ , which controls a device described below. The depressions 158g to i58 ₁₀ are offset from one another so as to consecutively channels I53 _X face during rotation of the drum to I53. ₅ The various switches 16S ₁ to i68 ₅ cannot be closed at the same time. The coin or pieces of money inserted travel on with the drum 158 and, in a certain position of this drum, fall into a cash register (not shown).

In each of the lines connecting the contacts 86 to the corresponding contacts, like 250, 251, a solenoid (not shown) is switched on, which controls the output device management of the relevant purchase item operated.

To allow surplus coins to fall out again, the lower ends of channels i53 _x to 1535 are designed as follows:

The lower walls are slotted along a certain length, for example at 171 (Figs. 13 and 14), so that the corresponding coins can roll out through the slots and get into a re-dispensing channel through a metal guide. The five slots 171 of the channels are usually closed by the bars of a rake 172 so that the coins cannot fall out. The rake 172 is connected to one arm of an angle jack 220 (Fig. 14) which rotates at 221 and a weight 222 acts on the other arm. This tends to move the rake 172 against the slots 171 so that they are released. However, this displacement is prevented by a snap spring 223 which is usually in engagement with an angle lock arm 224. One arm of a lever 225 can act on this arm, with the other arm of which the core of a solenoid M _{5 is} mechanically connected. Thus, as soon as the solenoid M _{3 is} energized, the arm 224 releases the rake 172 and the slots 171. The rake 172 is returned to its closed position by a rod 226 and a rotatable arm 227 on which a cam 228 of a rotatable

Drum 49 acts when it is returned to its rest position.

The rake 172 carries the metal strips 6 _X to 6 ₅ (Fig. 10). On the shaft 166 of the drum 158, a disk 175 is firmly seated with a ratchet mechanism 36; 37 is provided, which is intended to come into engagement with a ratchet wheel 46 and to couple this temporarily to the disk 175. As will be explained later, the ratchet wheel 46 is necessarily connected to the rotatable drum 49 (Fig. 10 a), which is used to determine the amount of money thrown in. The ratchet mechanism consists of two pawls 36, 37, which are rotatably mounted on the disc 175 and of which one (36) under the action of a spring 40 constantly strives to come into engagement with the ratchet wheel 46, but usually through the second pawl 37 is prevented.

This pawl 37 is held in the corresponding position by a spring 41 which presses against a stop pin of the disc 175; however, it can be removed from this position when the disk 175 is rotated, thus releasing the pawl 36 in that it comes into contact with one of five stop disks 4S ₁ to 435 which are arranged around the disk 175. Each of the stop disks 4 ^ ₁ to 43 ₅ has a flat 43 ₆ which is large enough to allow the pawl 37 to pass freely when it is located opposite the disk 175. If the stop disk 43 is rotated somewhat, however, the pawl S7 'abuts it and releases the pawl 36. Each of the stop disks 4 ^ ₁ to 435 is rotated by the core of one of the solenoid cores m _x to m ₅ by means of a linkage 176 when the corresponding solenoid is energized, ie when the associated one of the switches 16S ₁ to i68 ₅ through a coin inserted is closed. ; The ratchet mechanism 36, 37 is accordingly _{deflected by one of the stop disks 43 X} to 435 depending on the value of the coin. Each of the stop disks 4 ^ ₁ to 435 is held in the rotated position by a hook lever 42 which, under the action of a spring 42 _X, engages in an incision in the relevant one of the stop disks 4 ^ ₁ to 435. The hook lever 42 can, however, be released after a certain time by one of the corresponding cams 4S ₁ to 45 _{5 of} the disk 175, whereupon the stop disk is then brought into its rest position by a counterweight (not shown). On the other hand, the pawl mechanism 36, 37 is decoupled by one of the fixed stops ₁ to 395, which acts on a pin 38 of the pawl 36. Depending on the position of the relevant fixed stop ₁ to 395 in relation to the associated stop _{disk 43 X} to 43 g, the ratchet wheel 46 will rotate through a certain angle with the disk 175. These positions are chosen so that the ratchet wheel 46 moves by an angle which corresponds to the value of the coin inserted. Assuming that the tooth pitch corresponds to 0.05 Fr., then z. B. turn this ratchet wheel 46 by ten teeth when throwing a 0.50-Frank piece. Fig. 15 schematically illustrates the mutual positions of the stop disks 43 and the fixed stops 39. In this figure, the hatched areas represent dead angles in which no switching movement of the ratchet wheel can take place.

As indicated above, the ratchet wheel 46 is inevitably connected to the drum 49, which is shown in Fig. 10 a three-dimensionally and on the right underneath it. It is made of insulating material and rotates inside. a hollow cylinder 51, also made of insulating material, the inner surface of which is shown in FIG. This carries a row of 50 contacts 86 in which the contacts are equidistant from one another by the dimension t. Each contact 86 corresponds to an amount of money between 0.05 CHF and 2.50, e.g. B. 0.05, 0.10, 0.15, 0.20 ... 0.95; 1, -, 1.05 ... 2.45, 2.50 and is connected by a line such as 250, 251 to that contact 71 of the purchase item selector that corresponds to a purchase item at this price.

Since it is assumed here that the two contacts 71 shown in Fig. 10a relate to objects of purchase which cost the same price, 0.65 Fr. . On the drum 49 is a contact ¹ Jj (Fig. 16) present, which is just as long as needed to any of the contacts 86 with an oppositely located contact ring 89 of the hollow cylinder 51 connecting to, and a width 5 that is equal to each contact 86 is.

Depending on the value of the coin inserted, the ratchet wheel 46 and rotate with it the drum 49 at an angle which corresponds to this value. Contact 77 comes into contact with that of the contacts 86 which corresponds to this value. Consequently this value is set.

The drum 49 actuates an arm 98 by means of a fork 97 (FIG. 10 a, below), which arm is firmly connected _{to the contact bridge 99 of the switch S 1.} When the drum 49 is in its rest position, the contact bridge 99 connects the contacts 100 and 101, which are switched on in the circuit 173, 174 of the solenoid Af ₁ (Fig. 10), so that this circuit is closed at 100 and 101 ( Fig. 10a) takes place. If, on the other hand, this drum 49 turns out

rotates this rest position, it opens the circuit ioo and ιοί and brings the contact bridge 99 with contacts 102, 103 in contact, one of which (102) through a line 106 with the contact ring 74 of the purchase item selector and the second (103) by one; Conductor 105 are connected to a contact 108 (Fig. 10) of a switch S ₃ , the contact bridge 163 of which is firmly connected mechanically to the contact bridge 165 of the switch S ₂ by a shaft i63 _x. The other contact 107 of this switch S _a is connected by a line 109 to the ring contact 89 (FIG. 10 a) of the hollow cylinder 51.

From this it follows on the one hand that, once a coin has been inserted, the circuit of the solenoid M _{1 is} closed at S ₁ and that the coin causes the excitation of this solenoid M ₁ , whereby the motor Af ₀ rotates forward, on the other hand, that, actuated as soon as the latter, the drum 49, is interrupted the circuit of this solenoid M ₁ at _S1.

Since the depressions 158g _lb of the drum 158 offset to I58 against each other are ■, the solenoids may be energized only after the other. The offset is calculated in such a way that the switching, which can be effected by a given solenoid, is already completed before a new solenoid is again energized and a new switching can thus take place.

The remainder of the money determiner has the following facilities:

To determine the amount of money thrown in, the motor M ₀ rotates forwards, ie in the opposite direction to the clockwise movement. ,. To \ agree to be surrendered Amount loading, he turns the other way around, ie in! Direction of clock hand movement. For this purpose the solenoid M ₅ (Fig. 10) is energized, the core of which is mechanically connected by a rod 110 to one arm of a lever, the other arm of which can act on an arm: 164J of the contact bridge 165 of the switch S ₂ } , to bring them from the contacts to the contacts VV j RR, WO · is \ changed by the rotation of the motor M _0th

One sits on the shaft 166 of the drum 158

go to another disk 48 (Fig. 10 a), which, similar to disk 175, carries a ratchet mechanism 336, 337, 1 which is intended to temporarily couple this disk 48 to another ratchet wheel 47, whose teeth, however, match the teeth of the ratchet wheel 46 of the disk 175 are directed in opposite directions and can therefore only come into effect _{when the motor M 0 is reversed.} The ratchet mechanism 336,337 is in | Activity set by stop disks, such as i 52 _X to 52 _B , and out of action by fixed j stops 339 _X to 3395. As will be explained later, the various stop _{disks are operated by means of rods through solenoids W 1} to n _{5 of} the residual dispenser.

Depending on the position of a stop 339, it becomes the associated stop disk 52 the ratchet 47 and thus the drum 51 rotated backwards by an angle that corresponds to the Value of a 0.05, ο, ΐο, o, 2o-, 0.50, i-Frank piece is equivalent to.

To reverse the direction of rotation of the motor M ₀ and thus of the drum 49 (Fig. 10a and 16), a second row of contacts 87 is provided on the hollow cylinder 51, which are arranged in a ring and are evenly spaced from each other by the dimension t . Each of these contacts corresponds to an amount of money between 0.05 and 2.50 CHF, e.g. B. 0.05, 0.10, 0.15, 1, -; 1.05 ... 2.45, 2.50 Fr. and is connected to the relevant contact of the fixed hollow cylinder 150 (Fig. Ioa) of the purchase object voter, which corresponds to an object of purchase at this price. Since it is assumed that the two contacts 72 shown in Fig. 10a relate to objects of sale which cost the same price, both are connected to a busbar 261 of the hollow cylinder 51.

Opposite the row of contacts 87 is a contact ring 91 (Figs. 10a and 16), which can be connected to this contact 87 by a contact 79 of the drum 49. The contact ring 91 is connected by a line 113 to the solenoid M ₃ , which on the other hand is connected to the contact 75 _{via line 114, switch S 4, line 118.} The length of the contact 79 is equal to t (z -1) + b if ζ is the number of contacts 87 and δ is the length of the contact yj .

The rest of the output is done as follows:

On the inner surface of the hollow cylinder 51, further contacts are provided which belong to the remainder of the money dispenser, namely an annular row of contacts 88 (Fig. 10a and 16), in which the contacts are equidistant from one another by the dimension t. Each contact 88 corresponds to a certain amount of money between 0.05 and 2.50 Fr. B. 0.05, 0.10, 0.20 ... 0.95, i, ---, 1.05 ... 2.45, 2.50 Fr., and is the fixed contact 73 with the relevant contact Purchase item selector drum 150 electrically connected. Since it is assumed that the two contacts 73 of the cylinder 150 illustrated in Fig. Ioa relate to purchase items which have the same price of e.g. B. cost 0.65 Fr., they are connected to a busbar 262 of the hollow cylinder 51. Opposite the row of contacts 88 are ring contacts 92, 93, 94, 95, 96, each of which corresponds to a type of coin that can be issued by a self-seller. On the rotating drum49 there are five contacts 80, 81, 82, 83, 84 (Fig. 16)

to

B62167

present, which also belong to the residual money dispenser and are intended to connect the above-mentioned contacts 88 and contact rings 92 to 96 of the stationary hollow cylinder 51. The first contact 80 corresponds to the 0.05 franking piece and serves to connect any one of the contacts 88 to the contact ring 92 and has the length b. The second contact 81 corresponds to the 0.10 franc pieces and has a length equal to t - \ - b and connects any pair of the contacts 88 to the contact ring 93 without touching the contact ring 92. The third contact 82 corresponds to the 0.20 franking piece and is intended to connect four contacts 88 to the contact ring 94 at the same time without touching the contact rings 92, 93 lying in between. It therefore has a length of 3 t + b.

The fourth contact 83 corresponds to the 0.50 Frank pieces, has a length 9 1 -j- b and is used for the simultaneous connection of ten contacts 88 with their contact ring 95 bridging the contact rings in between. The last contact 84 corresponds to the i-frank pieces. It has a length of igf-j-δ and can connect twenty contacts 88 to the contact ring 96 at the same time.

The various contacts 80, 81, 82, 83, 84

are arranged one after the other on the drum 49 and in any case offset by a pitch t with respect to the preceding one.

The following consideration has to be given to choosing the length

of contacts 82, 83, 84:

At 0.45 francs, you still have to pay with 0.20 franc pieces, but not more at 0.15 francs, so there remains 82 minus the reset for the length of the contact corresponding to the 0.20 franc pieces this latter by a division t:

0.05 ~ ~~

At 0.95 Fr. you have to pay out with a 0.50 Frank piece, but at 0.45 Fr. no more, so the length of contact 83 corresponding to these pieces is:

(0.95 - 0.45) __, _t ,, _ ",,,

0.05

At 1.95 Fr. you have to have an i-Frank piece are paid, at 0.95 Fr. no longer, so the length of the contact is 84 that this Pieces corresponds to:

(1.95 - 0.95)

= 20 1 -24- δ = ig t + b. 0.05 ^ ^y ^

The money remainder determiner has five vertical tubes 13I ₁ , 13I ₂ , 13I3, 13I ₄ , 13I ₅ (Fig. 11), which are arranged next to each other and in which one type of money is stacked on top of each other, z. B.

13I ₁ 0.05 Frank pieces, 13I ₂ 0.10 Frank pieces, 131 ₃ 0.20 Frank pieces, etc. At the lower end of each tube there is a toothed wheel I32 _X to 1325 (see also Fig. Ioa), which, when partially turned below the coin column, takes a coin with it in order to bring it through one of the channels i33 _r to 1335. All channels open into a larger channel 134 which ends outside the box of the self-seller. Each wheel 132 is firmly connected to a shaft 135 on which a ratchet wheel 136 sits. This is rotated by one of the solenoids% to n ₅ , the core of which by means of a rod 137 of an arm 138 of a shaft 139, another arm 140 of this shaft 13g, a rod 141 of a lever 142, a rod 143, a lever 144, a rod 145, a pawl 147 of a last lever 146 is actuated. On each shaft 148, a stop plate is fixedly attached to 525 52 _X, so that when one of the solenoids -W ₁ -W attracts ₅ its core and bring a coin to hand, the stop disc for the corresponding latch plant 336 in question, 337 in activity sets and thus causes a reverse rotation of the ratchet wheel 47, the extent of which corresponds to the value of the coin issued.

The excitation of the five solenoids -W ₁ to n ₅ is controlled by the contacts 80, 81, 82, 83, 84 of the drum 49 (Fig. 16). For this purpose, the five contacts 92, 93, 94, 95, 96 of the hollow cylinder 51 (Fig. 10 a) are each connected to the terminal of one solenoid _{by a line 19O 1} , igo ₂ , igo ₃ , igo ₄ , igo ₅ , the other terminal of which is connected to two contacts 63, 65, which _{can be brought into connection alternately through the contact bridge 200 of a switch S 5} with two contacts 62, 64. All contact pairs 62, 64 are connected to a common conductor 201, which leads to one contact 202 of a common switch S ₇ , the contact bridge 203 of which can connect this contact 202 to a contact 204. Finally, this contact 204 is connected by a line 205 to the contact ring 76 of the purchase item selector.

The switch S ₇ is controlled in any way by cams of the drum 158 so that it is only closed when the switching wheel 47 is not switched, as is switch S ₄ .

The contact bridge 200 of each switch S ₅ is firmly connected to an arm 208 which can be taken along by an arm 206 of the shaft 139 if this shaft rotates in a direction opposite to the direction of rotation of the clockwise. The various arms 208 of the five switches S ₅ are connected to one another by a rod 20g in such a way that they all have to move with one another.

By actuating the shaft 139 by the associated one of the solenoids n _t to n ₅ , the circuit is interrupted at 62, 63, since the fixed arm 206 takes the loose arm 208 with it by means of a pin. All loose arms 208 are deflected by the rod 209 and the circuits 19O ₁ to 19O ₅ at 62, 63 are interrupted. In contrast, the circuit 19O ₁ , 96 is closed again at 64, 65 because the fixed arm 206

to and with it the contact bridge 200 is rotated. But this only happens with this one switch S ₅ , all the others remain open until the whole system returns to the rest position.

The parts 137 to 146 are returned to the neutral position after the respective solenoids W ₁ to Ji ₅ have attracted their cores. The following must be taken into account: If CHF 0.45 is to be paid out, CHF 0.20 twice and then CHF 0.05 must be given out. The circuit of the solenoid W ₃ , which causes the issuance of the 0.20 Frank pieces, would thus remain closed after the payment of the first piece and prevent the return of the parts 137 to 146 to the zero position. In order to avoid this, a switch S _{11 is} switched on in the relevant circuit, which is usually closed, but can be temporarily opened by a cam 67 of a cylinder 6 ^ _{1 which is} inevitably rotating with the disk 48 in order to allow the return of the parts 137 to 146 in the neutral position by breaking the solenoid circuit.

Between the row of contacts 87 and the contact ring 91 there is another contact ring 90 which is used to return the switch S ₂ (Fig. 10) to the zero position 0-0 and thus to stop the motor M ₀ . For this purpose, the contact ring 90 can be connected to the contacts 87 through a contact 78 of the drum 49 if, during the reverse movement of this drum, the contact 78 touches the contact 87, which corresponds to the purchase price of the

+5 corresponds to the object of purchase. It should be noted that the contacts J ¹ J, 78 of the drum 49 are at the same level, and that, on the other hand, the beginning of the contact 79 and 80 is set back by the pitch t with respect to the contact 78.

So offset.

The mode of operation of this exemplary embodiment is as follows:

In the rest position, the switch S _{2 is} in the 0-0 position, in which it interrupts the circuit of the motor M ₀ (the motor is therefore at a standstill). In this position, the switch S _{3, which is inevitably connected to S 2,} opens the circuit 105-109. None of the switches 16S ₁ to i68 ₅ is closed and none of the solenoids W ₁ to m _{5 are} energized. The rotatable drum 151 of the purchase item selector is in such a position that none of its contacts 68, 69, 70 prevent the contacts 71, 72, 73 with the contact rings 74 »75, 76. The rotatable drum 49 is in such a position that it does not put any of the contacts 86, 87, 88 with the contact rings 89, 90, 91, 92, 93, 94, 95, 96 in connection. It is assumed that a buyer wants to receive an object of sale which costs 0.65 francs. For this purpose he rotates the drum 151 of the purchase item selector by means of the snap crank so that he brings the contacts 68, 69, 70 to the corresponding contacts 71, 72, 73, with which he connects the latter to the contact rings 74, 75, 76.

The following cases can occur: Either the buyer pays with a single one One coin too many (case a), or he throws in several coins one after the other represent too high an amount (case b), or he pays in correctly, or he pays in too little.

If we assume that the buyer throws in CHF 1 (case a), then CHF 0.35 must be given out in the simplest combination: 0.20 + 0.10 + 0.05 Fr. are paid out will.

The i-Frank piece rolls down the corresponding channel I53 ' ₄ and establishes the connection between the metal strip 6 _{4 of} the rake 172 and the contact ring 1584 of the drum 158. This energizes the solenoid M ₁ , which brings the contact bridge 165 of the switch S ₂ from the zero position 0-0 to the position VV. The motor M ₀ is thereby switched on and moves in the forward direction, ie in a direction opposite to the direction of clockwise movement. The motor M _{0 takes} the drum 158 with it, so that the relevant recess 1589 comes to lie under the i-Frank piece, picks it up and moves on with it. The coin operates the switch i68 ₄ and then falls into the cash register. By actuating the switch i68 ₄ , the circuit of the solenoid m _{4 is} closed, so that this solenoid m _4, the stop _{disk 43 4} ■ rotates, and the pawl 37, which now rotates with the disk 175, comes into contact with this stop disk and the latch 36 releases. The pawl 36 immediately engages the toothing of the ratchet wheel 46 and couples it to the disk 175 in order to disengage it again when it _{hits the stop 3g 4} , ie when the ratchet wheel turns twenty

Has rotated divisions. Because: -? - ~ = 20.

During this time, the coin has left the switch i68 ₄ , so that the solenoid m _{4 is} no longer traversed by the current and _{allows the stop disk 43 4} to come to its rest position under the action of a counterweight as soon as the hook lever 42

Ϊ2

S6M67

under the action of the cam 45 it is also allowed.

By actuating the ratchet wheel 46

If the drum 49 is rotated by twenty divisions relative to the Höh lon cylinder 51, so that the contacts 77, 78 are the i-Frank contacts 86, 87 with the contact rings 89, 90 connect

and contact 80 brings 0.95 Frank contact 88 into contact ring 92.

This determines the value of the i-Frank piece that has been thrown in, with 49 and 51 standing now in the position shown in Fig. 17.

If the buyer throws several coins one after the other into the self-seller, the too high an amount for the selected object of purchase represent (case b), the following will take place:

As soon as after inserting the coin, through which the deposited amount just exceeds the value of the purchase object, for example after inserting the i-Frank piece for the purchase object, the value of which is 0.65 Fr., the solenoid M _{8 is} energized, the one Moving the rake 172 by the counterweight 222 allowed. From now on, all further coins thrown in fall directly out of the channels 153 and out of the apparatus without being able to close the circuit of the solenoid M _1.

If, after the selected item of purchase has been issued, the circuit of the solenoid M _{2 is} closed and the drum 49 is returned to its zero position, the rake 172 is moved to its normal position by the cam 228 of this drum 49 and then again by the snap spring 223 held. :

Is just being paid in correctly, e.g. B. 0.20 + 0.20 + 0.20 + 0.05 Fr. (case c), so-'■ splints following:

The three 0.20 franc pieces are superimposed; each other, so that the lowest contact 63 '■. of the corresponding channel 1533 connects to the metal ring 1583 of the drum 158, while; rend the 0.05 franc piece the connection | between the contact of the channel Ι53 _Χ and the metal ring 15S ₁ . If a depression 158 first comes under the 0.05-franc piece, this is continued and the drum 49 is rotated forward by one division, then a depression comes to lie under the lowest 0.20-franc piece, which continues and a further switching of the drum 49 by four pitches is effected. With a second further rotation of the drum 49, the second 0.20 franc piece and with a third the third 0.20 franc piece come into effect, so that finally the contacts 77, 78 j the 0.65 franc -Connect contacts 86, 87 with the contact rings 89, 90. As soon as this ■ circuit is completed, the current ■ ^; circle of the solenoid M _{2 closed} by the switch S ₄ . It brings the switch S ₂ back to the open position 0-0, the motor M ₀ stands still and the selected object of purchase arrives at the output, the drum 49 returning to its rest position through the 'counterweight 300'.

j None of the circuits of the Soj lenoids M ₁ , n ₂ , % come into effect, since the contacts 80, 81, 82, 83, 84 do not have the 0.65 Frank contact 88 with the contact rings 92 to 96 connect can.

If too little is thrown in for the price of the selected object of purchase (case d), the motor M _{0 is started} in the forward direction by the paid-in coin or coins and the drum 49 is switched forward by the corresponding number of divisions. A special device, not shown, ensures that the motor M ₀ after a certain number of revolutions, for. B. after one hundred revolutions of the disc 175 is stopped again, while the drum 49 remains in the position now assumed. The next buyer will therefore take advantage of the inserted coins if the current buyer does not prefer to get below the inserted money by adjusting the purchase item selector accordingly.

In the Kaufgogenstand selector, the fixed hollow cylinder 150 and the rotatable drum 151 can be replaced by another arrangement. The various contacts can be arranged on a circular disc if there are few items to buy ; plugs can be arranged as with resistors. Translational movements instead of rotary movements can also be used. The same also applies to the drums 49 ^ and 51. The rows of contacts 86, 87, 88 and the contact rings 89, 90, 91, 92 ... can also be arranged in concentric circles.

The switches S ₅ can be omitted, since the switch S ₇ in and of itself is sufficient, because during a switching no more than one circuit of the solenoids% to n _{5 is} switched on.

By appropriately selecting the contacts 80, 81, 82, 83, 84, the money can be released in a different combination than the one specified.

Several ratchet mechanisms can be provided on the disks 175, 48. The busbars 260, 261, 262 do not necessarily have to sit on the hollow cylinder 51, but can be combined on a special plate.
