Electric vending machine.

The subject of the present invention is a self-selling apparatus of books, photographs, cards, filled parcels (such as with tobacco, cigars, candy, Fruits etc.) or vessels filled with liquid and the like, in which the delivery of the purchased object with the aid of electricity in the manner effected becomes that the circuit supplying the delivery mechanism with current in the Hibernation is open in two places and the one interrupted by the thrown in Coin, the other is closed by pressing a button on the part of the buyer, so that the apparatus cannot be operated otherwise than by paying in the coin.

An apparatus set up in this way is shown in FIG. 1 in the front view, FIG. 2 in vertical cross-section and FIG. 3 in horizontal section according to FIG. 1. Fig. 4 is a side view of the hand contact, Figs. 5, 5 a and 5 b show the parts of the hand contact in various positions in front view. Fig. 6 is a schematic representation of the coin contact for various Price ranges. Fig. 7 is a longitudinal section of a modified device.

In the housing A (made of wood, sheet metal, cast iron, brass or other suitable material) compartments b are arranged in rows one above the other (FIGS. 1 and 2 show two such rows as an example), each of which accommodates one of the objects for sale . In Fig. Ι and 2 books are assumed as objects of sale. Each, object of sale rests on a horizontal, the bottom of the compartment forming and at d (Fig. 2) rotatably mounted lever (or plate) c, which is held in a horizontal position by a pawl e rotatable about f. Below each lever c an electromagnet h is arranged opposite the extended lower end of the associated pawl e. A table j is provided under each row of compartments; in the lowest of these tables are the coin insertion slots CDEF (Fig. 3, the grouping of which will be reported later). From each slot a channel χ leads downwards in a zigzag (Fig. 2), where two contact pieces k and A: ¹ lie under its mouth, which are brought into conductive connection by the inserted coin. One or, in the case of a group of slots, several contacts k ^l sit firmly on the armature / an electromagnet h ^1, which is rotatably suspended in I ¹ and pulled into the soldering position by the pick-off spring / ³ . The contact or contacts k are conductively connected to the -f- pole of a battery i ; From the —Pole of this battery, the line α goes through the winding of the electromagnets h ¹ h after the usually open hand contact D ¹ , from here to the switch D ² , to k ¹ . As soon as a coin touches kk ^x , the current path is closed here and only remains open ^{in D 1.} If you now establish a connection by pressing the button, h pulls the pawl e on the one hand, which pulls the lever c

Claims (1)

lets go, which now overturns under the weight of the object of sale and lets the latter slide onto the table j , whereupon the rubber spring / * turns it back into the horizontal position after the compartment; on the other hand, h ¹ also attracts its anchor /, which takes the contact piece k ¹ with it, so that the coin now passes through k and k ^l into the one below. orderly coin container falls, whereby the current path is interrupted here again; the electromagnets lose their energy; the pawl e is pulled again by its spring e ² over the lever c , which has been turned back underneath, and the armature / is pulled with k ¹ from Z ³ again towards k in the coin path. ^{A hand contact D 1 is} provided for each compartment b (or each sales item). According to FIGS. 4, 5, 5 a and 5 b, its device is such that the line α emerges in two leaf springs η and 0 ; of this, in the rest position 0, it rests against a leaf spring m , while η carries the button D ¹ and protrudes from m. If one depresses D ¹ , the circuit is closed with the contact between m and η (Fig. 5a), but as a result of the depression of D ¹ it is opened again immediately, in that the spring η then depresses the spring m (Fig. 5b). If you then release button D ¹ , m springs back and again establishes an electrical connection between η and 0 for a short moment until η has sprung back. By designing the distance between m and η differently in the various hand contacts, one can almost entirely avoid the fact that, after inserting only one price, several items are delivered for the single ^{price by pressing several contacts D 1 at the same time.} In order for the apparatus to be able to effect items of different price ranges and the buyer to pay in different types of coins and thereby exclude fraud, the compartments are divided into groups of the same price range and, as can be seen from FIGS. 3 and 6, a group of for each such group A tossing slot is provided, CDEF, and at the same time each such group is arranged in such a way that various coin combinations are possible in it. So z. B. the price range F allows three combinations of coin types. For each single coin, a slot of the appropriate width and width and for this a zigzag channel χ with contacts kk ^{l is} provided in the slot group. 6 shows that the current path is only closed when all the individual coins of the combination have been inserted into the relevant slots. As can be seen from FIG. 3, a switching device is arranged for each compartment, so that, as can be seen from FIG. 6, the compartments can be used for different price ranges with payment in the slot or slots set up for the latter. Each of these devices consists of a rotatable arm D ^{2 connected to the hand contact D 1} and just as many fixed contacts d ^l d ² d ³ d ⁴ as there are price levels, and each of which is conductively connected to the contact k 'of the slot group concerned is. In the apparatus of FIG. 7, the device is designed in such a way that several items of sale of the same price range are arranged one behind the other in compartment b. The foremost rests on a lever c, the following on a fixed table H, in which a slide H ^ is guided, which through the. guided to roll P cord h · with the most. Housing attached spring K is connected. An electromagnet Q is attached to the slider, and its armature J , which is also (rotatably) attached to H ² , engages with its lower end, designed as a locking cone, into a locking rack I fixed to H. Each time a purchase is made, the foremost item is always given out by means of the device described with reference to FIG. 1. When the lever c is then turned back into its horizontal position, it closes the circuit of a battery i 'in r r ¹ , which is guided by the winding of the electromagnet Q. The latter pulls its armature J , so that it lifts it out of the rack I , and by the pull of the spring K the whole row of objects of sale in the relevant compartment b is pushed forward until the foremost one presses against r and thereby the circuit the electromagnet Q opens again; now the armature J with its cone falls back into the rack / and thereby fixes the slide H ^2. The next following behind the first sales item is held in place by the pressure of the spring S when the former is delivered. Patent claims: ι. An automatic sales apparatus, characterized in that the objects of sale rest on rotatably suspended levers (or plates) c , which are held in a horizontal position by pawls e , which form the armature of electromagnets, and that the latter are connected to a battery by two contacts is produced, one of which is closed by the inserted coin or coins by means of the fixed piece k and the movable piece k ¹ and the other of which is closed by the buyer by pressing a button D ¹ , and the latter concludes at the same time the activation of a second Electromagnet h ^l , which by pulling the piece k ¹ causes the coin to fall through and thereby interrupts the connection with the battery again (Fig. 2). In connection with the in claim ι. The arrangement of the contacts kk ^{l, as} indicated in the apparatus, consists of several parts, determined by coins, in a conductive connection, so that different price levels can be paid for in different types of coins (Figs. 3 and 6), in connection with the arrangement of a switch D ^% for each Compartment (in the ^{line leading from Contact D 1} to piece A: ¹ ), so that each compartment can also be used for the sale of a lower or higher price range (Fig. 6). The modification of the apparatus according to claim 1 shown in Fig. 7, characterized in that several objects of sale are arranged one behind the other in each compartment and, after the first object has been delivered, the others have been pulled forward by means of a slide H ² by a spring ' K, the one in which Rest position in a ratchet / grabbing pawl J forms the armature of an electromagnet Q. whose circuit is closed by the lever c when it returns to the horizontal position.
