Description

The invention relates to a self-seller for gas ο. Like., in which a majority rotated by measuring wheels through a coin holder and their movements by means of a S epicyclic gear reduction gear can be transferred to a differential setting mechanism, according to patent 637 645. The invention is characterized in that only one of the measuring wheels moves during insertion one of the coins to which the facility responds receives and its movement over the reduction gear transfers to the default mechanism, while when throwing a other coin setting the device in motion locks the measuring wheels together and their movement via the epicyclic gearbox directly with a Transmission ratio of 1: 1 is transmitted by the measuring wheels and the so Moving impeller gears as a whole.

According to the invention, a hammer plate is also set up so that its one against the Axis of rotation of the lock is given to directional movement, when in use a smaller coin. This movement engages a tooth at the top of the Hammer plate or the like in both measuring wheels. The hammer plate is also for an additional Pivoting movement when inserting a larger coin is set up through which a tooth at the opposite end of the Hammer plate can come into engagement with only one of the measuring wheels while in use of a coin of an intermediate size, the amount of pivoting movement of the hammer plate is such that it does not go into any measuring wheel can intervene.

In another type of coin acceptor according to the invention are for Coins of different sizes separate hammers for actuation by the corresponding one Coins provided. The hammers are next to each other and are set up so that the one coin corresponds The hammer can be operated independently, while the hammer corresponding to the other coin also operates when it is operated takes the first hammer with it, so that there is an engagement in both measuring wheels.

According to the invention, the coin holders are also so in the last embodiment set up that when the coin pickup is rotated, the smaller coin that comes with the inner periphery of the coin acceptor housing comes into contact to be pivoted through such an angle, namely with its outer edge against the adjacent

hard to coin holder that it wtrd triggered in the same position "as a larger d ß

The device triggered by inserting coins according to the main patent has been modified according to the invention in such a way that the drive takes place in one case by the reduction gear, while in the other case a drive with a transmission ratio ι: ι takes place. Such a design is shown in FIGS. Two coaxial measuring wheels a, b sit in a housing c, which contains the coin acceptor d . One or the other of the measuring wheels. can optionally be operated by one of the two coins. The measuring wheel b sits on a spindle b ¹ , which has a fixed gear wheel b ^% , through which the valve control device (default mechanism) by means of a sub i B h D

(G

reduction gear receives a movement. The l ¹ S

indel b ^{1 lies in a foot & 4} seated with play, which egt in a tubular sleeve a ¹ which passes through the wall of the housing c . At the inner end sits the second measuring wheel a, while at the rear end of the tubular sleeve a ¹ a segment plate or a -Arm e is attached, which serves as a gear carrier; it carries a spindle e ¹ which is arranged parallel to the spindle b ¹ . A gear e ² and a pinion e ^{3 of} the reduction gear are firmly seated on this. A plate e ⁱ supports the outer end of the spindle e ^{1 of} the plate e by means of pins or screws e ⁵ . The gear wheel e ² meshes with the pinion b ² , while the pinion e ³ meshes with a gear wheel / an intermediate spindle f ^x which is arranged at the rear end of the spindle b ¹ and coaxially with it. The spindle f ¹ is held in a suitable manner by a transverse frame plate g, the g in a suitable manner by the frame plate supports ^1, while another transverse plate g ² sits at the back to the differential default work between the plate g ² and the plate to hold g.

The spindle b ¹ is set off at the rear end so that it can enter a central cylindrical recess which is provided at the adjacent end of the intermediate spindle f ¹ or within the gearwheel /.

The sleeve £> ⁴ has a flange at the inner end against which a resilient washer b ³ can be placed. This can lie against the rear of the measuring wheel b , so that a certain pressure can be exerted by which rotation of one measuring wheel is avoided when the other is rotating. For this purpose, a resilient washer g ³ can also be provided on the tubular sleeve a ¹ on the rear side of the frame plate g ¹ . Other means can be provided to provide sufficient friction to avoid rotation of one measuring wheel when the other rotates.

The movement is transmitted from the reduction gear through the gear / to its differential gear located on the rear. The gear ratio of the gears is determined according to the value of the coins by which the device is to be operated. The coin pick-up device can either wake up the measuring wheel b alone or lock the measuring wheels α and b to enable direct drive or a transmission ratio of 1: 1 between

6S9402

to reach the measuring wheels and to the default work. For this circuit z. B. Coin acceptors can be used as described below.
When the device is operated by one type of coin, a hammer engages the measuring wheel b (Fig. Ι to 3), and by rotating the device operated by the coin slot, the pinion b ² at the outer end of the spindle b ¹ and the epicyclic gear train are low Reduction ratio between coin mechanism and default mechanism switched on. When actuated by the other type of coin, the hammer lies against the two measuring wheels α and b, so that the corresponding spindles b ¹ , a ¹ and the gears b ² , e ² are locked together and the gear f is given a direct movement. This movement is transferred to the differential gear that serves as the default mechanism.

The differential default mechanism, as shown in the drawing, consists of two coaxial sun gears h, h ¹ , one of which, h, sits on the end of the intermediate spindle f ^1; the other, h ¹ , is arranged on a concentric sleeve h ² , which is provided further back, in which the spindle h ^{s is} rotatably arranged. This extends forward so far that it engages in a central recess of the spindle f ^1. Between the gears h and h ^{1 there} is a planet gear carrier fo ⁴ on which planet gears h ^s , h ^B are arranged, which mesh with the associated sun gears h, h ¹ . As a result, the drive is transmitted from the intermediate spindle f ¹ via the gear h at its outer end. A valve control element or a cam disk or the like is arranged at the rear end of the spindle h ^{s of the differential gear.} Through this, a movement can be given to the valve lever regulating the consumption quantity. The sleeve, h ^{2 of} the differential gear is

4-5 would move through the knife by means of a worm; ¹ issued, which engages in a worm wheel / the sleeve h ^2. This allows the gas valve lever to be turned back by the gas meter to close the valve. At the rear end of the spindle h ^{s of} the differential gear, a pinion k is provided which engages in a toothed sector k ¹ , by means of which a pointer k indicating the coin supply is adjusted. The differential default mechanism can also be designed as shown in FIGS. 1 to 3 of the main patent.

In the device described, a larger coin causes the rotation of the measuring wheel b and the spindle, by means of which the intermediate spindle is given a low transmission ratio by the reduction gear, from which a movement is given by the valve control device through the differential setting mechanism. If, however, a smaller coin is inserted, the movement of the measuring wheels coupled to one another is transmitted directly to the intermediate spindle and transferred from there to the differential default mechanism.

One type of coin acceptor for a device triggered by the insertion of coins according to FIGS. 1 to 3 is shown in FIGS. The actual coin acceptor α extends transversely outward from the disc b on which it is seated. This lies next to the inner surface of the tariff change disk c, which closes the housing e. A handle / sits on the pin through which the rotatable disk b sits on the tariff change disk c. The disc b has a coin slot b ¹ , which can be brought into congruence with a corresponding coin slot of the tariff change disc c when the disc is rotated. .

A pivotable coin disc α ¹ is arranged inside the coin receiver α in such a way that it is pressed downwards under the pressure of the coins introduced into the coin receiver against the resistance of a helical spring a ² , which again causes the return or the upward movement. The spring is connected at one end to a pin α ³ , which is located on one wall of the coin acceptor, and attached at the other end to a pin α ⁴ , which " sits on the disc a ¹ and passes through the wall of the coin acceptor α extends through overlapping slots α ^5. The upper parts ^{ae of} the slots are straight and are parallel to the disk b. The lower parts a ⁷ are curved and designed so that the downward movement of the pin α ⁴ during the pivoting movement of the disk d ^{1 is} possible, which occurs when a larger coin is inserted into the coin receiver α . The disk a ¹ first executes a straight movement, which is caused by overlapping straight slots α ⁸ on the front and rear walls of the coin receiver α and through a pin α ⁹ , which sits on the disk a ¹ and passes through the slots α ^8. As soon as the downward movement of the pivot α ⁹ through the lower end of the slots a ^{8 has} ended, the disk a ^{1 leads} under d When printing the larger coin, a partial rotation around the pin o ° as long as it is possible through the lower parts a ^{7 of} the slots α ⁵ . ■

A hammer plate g is slidable on the coin acceptor on the side that

689432

lies next to the axis of rotation, arranged and connected to the disc c ¹ by the pin α ⁹ and the pin α ⁴ .

Near the upper end, a slot g ^{1 is provided} in the hammer plate g , which extends transversely through the plate and is curved for the most part according to the arc of a circle described from the axis of the pin a ^9. At the inner end ίο the curved slot g ¹ bends downwards and forms a straight connecting part g ² parallel to the turntable b. A pin g ^s is firmly seated on the adjacent wall of the coin acceptor a, which passes through the slot g ¹ and limits the movements of the hammer plate g. As shown in FIG. 6, when a smaller coin is inserted into the coin receiver α, the disk a ¹ and the hammer plate g connected to it are given only a straight downward movement, so that a double tooth g- ⁴ at the upper end of the hammer plate g "in the two measuring wheels h, f 'of the device can intervene, through which a direct drive of the valve control device takes place when the coin acceptor α is rotated, as described according to FIGS. 1 to 3. During this movement of the hammer plate, the slot g ¹ moves towards the pin g ^{3 in} such a way that the pin lies in the upper end of the straight part g ^{2 of} the slot g ^1. The pin a ° through which the hammer plate moves g and the disc a ¹ are connected, towards the lower end of the straight slits ώ ^{8 in} the walls of the coin receiver. If a larger coin is inserted (Fig. 7), the hammer plate g and the disc a ^{1 move} ■ first down, and then turn - the hammer plate g and the disk α ¹ corresponding to the larger coin around the fixed pivot α ^9. During this double movement, the double tooth g ^{4 of} the hammer plate g first rests against the two adjacent measuring wheels h, iand then steps back, as shown in Fig. 7, so that when the coin acceptor α rotates, the two measuring wheels are free from it, while the lower end of the hammer plate g, which is also designed as a tooth g ⁵ , "moves" forward and up moved in an arc of a circle to engage the wheel h , whereby the valve control device upon rotation of the -, ·; Coin acceptor by the reduction gear, as previously described, can receive a movement. '

In order to work in the manner described, the disk a ^l has essentially a circular or similar shape, especially in its upper part (opposite the slot), against which the coins lie when they are inserted into the coin acceptor. In addition to this circular or similar curvature, the disc also has a small depression or recess α ¹⁰ in which the smaller coin is placed when it is inserted into the coin holder after it has given disc a ¹ the limited downward movement a straight edge α ¹¹ which, when the disk α ^{1 is} partially rotated, assumes a position in which it presents a surface to the circular edge of the larger coin when it fully enters the coin receiver, which is approximately perpendicular to disks b and c .

The teeth g ⁱ , g ⁵ expediently form a component with the hammer plate g. For this reason, the metal of the hammer plate is bent at right angles to the side and then downwards at the upper end to form a double tooth g ⁴ on the upper part in a diameter plane that goes through the axis of the disks b, c. The double tooth extends over the front edge of the coin acceptor, so that in this way the double tooth can simultaneously engage in both measuring wheels h, i during the movement given to it when a coin of smaller size is inserted. At the lower end, the hammer plate is similarly bent at right angles to the side and then downwards to form a tooth g ⁵ , which is also arranged in the aforementioned diameter plane and is designed so that it only enters the measuring wheel h engages when the lower end of the hammer plate moves forward and upward when a larger coin is inserted into the coin acceptor.

In FIGS. 8 to 11, another type of coin acceptor is shown, which is also used for the device according to FIG. up to 3 is suitable. In this design, the tariff change disk a is provided at a certain point with two parallel slots α ¹ , α ² lying next to one another. Similar slots b ¹ , b ² are provided in the coin pick-up disk fr, which is provided on the inner surface of the tariff change disk. The coin acceptor, which is rotated counterclockwise in Fig. 9 (side view of Fig. 8) by means of a handle c «°, has two parallel plates d, e which are arranged perpendicular to disk b. The plates d, e are bent at one end to form projections at right angles by which they are connected to the disk &. At the opposite or outer end, one of the plates d is bent to form an end wall d ¹ . Two hammers /, g are arranged in a vertical plane (Fig. 9) that they are against the axis of the coin acceptor

are movable. For most of their length they have a width which is approximately equal to half the width of the cavity in the coin acceptor. They can move against the axis of the coin acceptor and are guided by means of pins g ¹ , f ¹ which go through slots e ¹ , e ² which are provided in a vertical plane in one wall e of the coin acceptor. Of the

ίο Hammer g is also guided in its movement against the axis of the coin acceptor by a second pin g ² , which also goes transversely through a slot in the wall e of the coin acceptor. The Hammerg

iS, since the hammer / overlaps it with a protruding part, the same movement as the hammer / is forced. The pins g ¹ , f ¹ are used to attack the lower ends of corresponding coil springs g ³ , / ² . The upper end of each spring sits on a pin which is attached to the wall of the coin acceptor or is integral with it. In this way, the hammers can normally be held in their extreme position, ie out of engagement with the measuring wheels h, i . The hammer / operated by a smaller-sized coin is slightly longer than the hammer if operated by the larger-sized coin. As a result, its upper end extends beyond the hammer g and forms an outwardly facing pawl. The pawl of the hammer / extends outward from the end wall of the coin acceptor to engage the larger and outermost measuring wheel i . The hammerg has a shorter hammer pawl at its upper end, which can only engage in the adjacent smaller measuring wheel h . The hammer / has a transverse part / ³ ,, which expediently has a groove for receiving the corresponding coin. This transverse part / ⁸ lies above a correspondingly transversely arranged, but thicker part g ⁱ on the hammer g, namely above the part of the link g ⁴ adjacent to the hammer g , so that in front of the link / ³ (FIG. 11) another larger coin is found on the link g * edition. These transversely arranged parts form the bases of adjacent coin holders for the smaller and larger coins. Part g * is thicker than part / ³ , about the width of the coin receiver pocket, so that a larger coin can rest ^{on it on the side of part / 3} which only engages hammer g . Because the transverse part g ^{4 is arranged} immediately below and in contact with the transverse part / ³ , however, when a smaller coin is inserted into the coin acceptor, both hammers will move downwards and engage the corresponding measuring wheels.

The transversely arranged part / ^{3 of} the hammer / has a laterally upwardly pointing part / ⁴ which delimits the space provided for the smaller coin and whose inner surface is inclined outwards (to the right in FIGS. 9 and 10). When inserting a smaller coin into the slot b ^{1 corresponding to part / 3} , both hammers are depressed. There is an engagement with both measuring wheels. When the coin acceptor is subsequently rotated counterclockwise in Fig. 9, the smaller coin does not remain parallel to the coin holder, but because it lies against the inner circumferential surface of the housing ^{because of the action of the coil springs / 2} , g ^{3, it is tilted into one position} , in which it lies on the inclined surface of part / ⁴ , with the outer edge towards the adjacent coin holder. However, the two hammers remain in engagement with their wheels. Both measuring wheels are rotated until they are released from the measuring wheels when they reach the outlet slot j ¹ in the lower part of the housing / exactly in the same position as a larger coin introduced through the slot b ² (FIGS. 9 and 10) falls off, releasing her hammer g .

According to another embodiment, the device triggered by the insertion of coins can be actuated by measuring wheels which are connected by a freewheel or ratchet device, so that a coin pick-up can be used with independently working hammers, while at the same time the measuring wheels on one of the drives are locked together. The design of a ratchet or freewheel device is shown in FIGS. The measuring wheels a, b are next to each other; the smaller, a, which can be actuated when inserting a large coin, is attached to a central spindle a ^l or forms a piece with it. The measuring wheel b, which is actuated by inserting a smaller coin into the coin acceptor, sits on a tubular sleeve b ¹ or forms a piece with it, which is arranged ^{concentrically to the spindle α 1.}

The freewheel device consists of a ratchet wheel which is firmly connected to the ..Zentralspindel a ^{1 by a Hülsec 1 in} such a way that it lies between the measuring wheels a, b after the parts have been assembled. The spindle a ¹ is expediently provided with two flats and the bore of the sleeve c \ is designed accordingly. Pawls c ² sit on the large measuring wheel b in such an arrangement,

that they can alternately engage the ratchet wheel, d. H. such that only one The pawl engages in the teeth of the ratchet wheel.

When the coin mechanism is coupled to the measuring wheel b when a small coin is inserted, the measuring wheel b is in direct engagement with the coin mechanism, and its movement is also transmitted to the neighboring measuring wheel a, ^lr > by the ratchet wheel c and one of ^{the pawls c 2} . When the device is operated by means of a large coin, however, the measuring wheel α is directly coupled to the coin mechanism, and the measuring wheel b ¹ S is not given any movement, which is subject to sufficient friction, the z. B. caused by a spring washer to brake it. A resilient washer d is expediently arranged between the measuring wheel α and the ratchet wheel c and secured against rotation by a lug d ¹ which engages in a slot or stop in the coin pickup housing e.

The coin pickup device, which is used to rotate the measuring wheels, can be of any design, but such that an engagement in only one of the measuring wheels a, b takes place alternately, depending on whether a smaller or larger coin is inserted into the coin pickup.

As shown in the drawing, the adjustable tariff change disk f carries the rotatable disk g of the coin acceptor, which is completed by a housing h of the usual shape. The tariff change disk / and the rotatable disk g have coin slots which are arranged next to one another. Separate slidable hammer plates i, j are also provided. The hammer plates lie one behind the other in the drawing and are held on a wall of the housing h by means of pin screws k which engage in slots m. These are parallel to the rotatable disk g. The hammer plates i, j have teeth ¹ , j ^l for coupling with the measuring wheels a, b. The tooth of the hammer plate i lies above the top end and the tooth of the hammer plate; The hammer plate j has a coin support f which is so wide that it extends over the entire width of the coin acceptor housing and serves to receive a coin which is inserted into the corresponding slot of the tariff change disk. The hammer plate i similarly has a coin support i ~ which is arranged above the coin support 'f of the hammer plate /. The coin support i ² has an upwardly facing wall i ^s . Each hammer plate i, j is under the action of a spring n, as shown in the case of the hammer plate i, in order to keep the corresponding hammer plate in the uppermost position within the coin acceptor.
