Description

GERMAN

It is known that the measurement results of scales and other measuring devices either on a stamp printing unit or to a registration device of the type of a booking, adding, punching card or similar machine to transfer. The usual means for this are tracking or scanning devices. They are set in motion as soon as the measuring element has reached an input position, and then, mostly Electrically through current surges and electromagnetic aids, the drawing rollers of the printing unit or the typing keys on the recorder.

If a measuring device, in particular a balance, with both a printing and a registration mechanism is equipped and every measurement result is immediately displayed, printed on common cards or the like and also still to be booked or registered in some other way - a demand that is being made more and more frequently becomes - then makes itself an obstacle that the working methods of the common stamp printer on the one hand and the usual booking and similar recording machines on the other hand, basically from one another are different. All are on the printing units in value groups, in the case of number printing units mostly transmitted measured values determined in decimals fairly simultaneously, regardless of whether the transmission happens by a follower or a scanning device. The registration machines can Compound values, in particular multi-digit numbers, always only in individual stamps Record (digits) one after the other, whereby the value only results from the ones caused during the transfer Switching steps results. One must therefore register a weight value with the number begin with the highest priority and always provide the same number of digits for each transfer case. To use such accessory works in a marketable form for measuring devices, but is in the In most cases this is an indispensable prerequisite for an inexpensive solution to the task at hand.

There are already devices known in which a number of measurement results, for example written or printed side by side, on a piece of paper. This is for example the measurement of a range of capacities of a telephone cable between individual conductors or held between them and earth. This is done using an appropriately modified typewriter, in which a special selector switch is provided that these capacities in sequence a measuring circuit switches and at the same time one attached to the carriage of the typewriter, of contacts coated contact strip is connected to voltage via a selector switch coupled to it.

have been named as inventors

special interlocks are activated to ensure that every measured value appears on the paper in the place assigned to it. The capacities are adjusted on a bridge and the adjustment capacitors manually or automatically actuated. Contact tracks are coupled to the capacitor axes, which means that associated magnets are corresponding Press keys on the typewriter. This known device is a simultaneous It is not possible to determine the measured values for all decades.

The invention relates to a device with the help of which in value groups, for example decimals, Subdivided measurement results immediately on both the stamp printing units and the registration units, preferably on commercially available booking, punch card, adding or similar machines by mecha niche and electrical means can be transmitted remotely.

The characteristic of the device according to the invention is that a switching device with Switching means which perform an idling operation during the mechanical scanning process of the measurement result and after completion of this scanning process, the electrical remote transmission of the measurement results the individual value groups in sequence to one or more registries set in motion is provided.

This creates a device that the measurement result at the place of its installation, for example by means of a luminous image, and also to the same or to one or more at any distance Make sure that the measurement result is printed correctly as well as posted or otherwise registered.

Contact so that the impulses reach the actuating magnets or the like on the two registration devices, namely the accounting machine H ₁ and a punch card machine H ₂ , in the correct order.

Before the weight value transmission with the aid of the device D , the finger 42 could find the exact time of the contacts 85, 86, 87 and 88 at one of the known and therefore not more closely connected to a supply network. In this way, the recording machines connected to the switches are operated. The prerequisite for this is that z. B. the motor 32 (Fig. 3), which sets the feature drums 11 and 21, also energize the magnet 52 connected to the bar 61 via the terminals V ₁ and V ₂ via a switch (not shown) and, as a result, the locking lever 53 for the switching mechanism 54 against the force of a spring

While the features of the four weight decade 5 according to Fig. 3 are simultaneously scanned by the rods 11a, 12a, 21a and 22a, the switch 42 is in the rest position (as shown), or it is as in the embodiment of Fig. 3 in the direction of the arrow moved without reaching one of the contacts 45 to 49 ίο. In this way, the contact banks 65 remain de-energized during the adjustment process for the carriers 62. This avoids sparks and wear. After the follower rods have reached a feature, and their contact carriers -

Brought locking disk 57 can pull. At the same time, the lever 53 actuates the switch 59 for the stop shaft drive motor 58. The motor 58 rotates the shaft 54 once fully (360 °) via a countershaft 58 α with a slip clutch. Because the locking lever 53 is pressed down by the disk 57 on the switch 59 during its rotation. Only when the groove 56 appears again over the locking lever, the return spring 53 α lets the lever jump in and thereby the switch 59 open again.

During such a revolution of the shaft 54, the cam disks 55 α to 55 η close the switches 555 α to 555 n, which are assigned to the cam disks. This is done in accordance with the

selected setting of the cams on the shaft and 15 rods 62 on the determined measured value entden requirements of the contact button to be spoken with the device F press and there firmly controlled recording machines. The switches 555 are held, the switch 42 reaches them one after the other when a booking machine is to take the contacts of the lines 45 to 48, whereby, as previously described weight values determined by the scanning unit D , in each of the number decades, in the same order like the con-20 associated magnet or the like in the (not shown bars 45 to 48 in Fig. 3 activated.
