DE335032C - Self-seller for electricity, gas, water or the like, in which the amount of sales material made available for the inserted coin is temporarily reduced to collect a basic fee - Google Patents

Description

According to the self-seller, the main patent is between the coin clutch and the default mechanism controlling the locking disk arranged a change gear, which is provided by the works clerk for the collection of the basic fee is set and after inserting the The basic fee automatically switches back to the original position by the customer.

The novelty of the invention is a simplified version of such a self-seller, at the same time, in order to simplify the operation, to adjust the gearbox for collecting the basic fee

ig the movement of the money container when the works clerk removes the money is used, which in itself is already known from similar self-sellers. The new version is characterized in that a wheel mounted on a lever is permanently connected to the coin clutch and alternately with the default mechanism and with the downshift gear for the basic fee payment device is coupled.

The drawing shows schematically the essential parts of the new self-seller. As far as possible, the parts are provided with the same reference numerals as the corresponding parts Parts in the main patent.

The gear A is firmly connected to the coin clutch 2. With this wheel, the gear α is in engagement with the toothed wheel A ^x which is fixedly seated thereon and which is mounted on an angle lever 24. This angle lever has its pivot point 25 near the axis of the coin clutch 2. By pivoting the angle lever, the wheel A ¹ can be brought into engagement either with the wheel 18, which is seated on the shaft 19 leading to the default mechanism, or with the ratchet wheel 13, which is used to convert the gearbox. The angle lever 24 is pulled by a spring b into a rest position in which the wheel A ¹ and the wheel 18 are in engagement with one another. From this position it is pivoted into the position shown in which the wheel A ^x and the ratchet wheel 13 are engaged by the movement of the money container c which, when pulled out, starts with a nose d on a projection e on the angle lever 24. After this pivoting, the angle lever 24 is held in its position by a pawl f loaded by a spring g . This pawl protrudes with an arm 27 in the path of the pin 26 on the ratchet wheel 13. A spring 40, one end of which is attached to the frame of the device and the other end to the ratchet wheel 13, seeks the wheel in an anti-clockwise direction to rotate an initial position determined by stops 41, 42.

Claims (2)

The mode of operation is as follows: When the works clerk comes to collect the money, the pawl f is disengaged, the angle lever 24 is pivoted clockwise and the wheel A1 engages with the wheel 18. When pulling out the cash drawer c, the angle lever 24 is pivoted counterclockwise, whereby the wheels A1 and 18 disengage, the wheel A1 and the ratchet wheel 13 come into engagement with each other. At the same time, the angle lever is locked in the new position by the pawl f. It remains in this position even when the cash drawer is pushed back into the device. If the coin clutch is now rotated clockwise after the coin has been inserted, the wheel A1 rotates counterclockwise and the switching wheel 13 rotates forwards in a clockwise direction. This continues until the pin 26 strikes the arm 27 and the pawl f disengages, as a result of which the coupling between .4 r- and 18 is restored. The amount of the basic fee to be charged in this way without influencing the default work is determined by the position of the pin 26 on the ratchet wheel 13 and the position of the stop 42. In order to change it, with the stop 42 in a fixed position, the disk can be provided with several holes into which the pin of your choice can be inserted. It is advisable to design the device in such a way that when the gearbox is set. for the collection of the basic fee, the possibility of continuing to purchase the means of sale for the coins that have not yet been used without paying the basic fee is eliminated. For this purpose, the device can be designed in such a way that the switch of the self-seller is opened or the tap is closed at the same time when the device is set for the collection of the basic fee. But you can also arrange a second switch or tap in series with the first and let this open or close. Such an embodiment of a self-seller of electricity is indicated in the drawing, i is a switch which is in series with the usual switch of the self-seller. It is held closed by a pin k on the angle lever 24 when the angle lever is in the position required for the engagement of the wheels .4 x and 18, that is, when the device is in the normal operating state. If, on the other hand, the lever 24, as previously stated, is pivoted by pulling out the cash drawer c, the switch is opened by the elasticity of its springs. In the drawing, at η, a wheel m which is in engagement with the ratchet wheel 13 is indicated with numbers, which is located behind a window in the housing wall of the device indicated by the dashed circle, and with the number appearing behind this window, the full number Basic charge still shows missing number of unit coins. P ATEifT claims: 1. Self-seller for electricity, gas, water 0. The stored wheel (A ¹ ) is permanently connected to the coin clutch (2) by a wheel (a) and is alternately coupled to the default mechanism (i8, 19) and the ratchet wheel (13) for the basic fee payment device, without the default mechanism to influence, 2. Self-seller according to claim 1, characterized in that the carrier (24) of the switchable wheel (A ^x ) controls a switch (i) or cock, such that the normally closed switch or open cock, when the carrier is deflected ( 24) is opened or closed from its normal operating position. 1 sheet of drawings.
