Telegraphic receiver for the production of perforated strips.

Patented in the German Empire on April 30, 1922.

According to the Union Treaty of June 2, 1911, priority is due to this application of the application in Great Britain on May 21, 1921.

The invention relates to a telegraphic Receiving apparatus, of the type used in particular in the Wheatstone system, in which by means of transmission via the line Recording or signal streams a perforated strip is produced, which is a Represents the second piece of the strip used in the loading station. This strip is safe in accordance with the punching process by a feed wheel led forward. To produce a sign, two electrical current impulses are namely a positive and a negative, required by the electromagnetic

table facilities are excited, in turn, the operation of the punching and the Regulate the feeding of the strip.

With the Wheatstone system, two current pulses are required to form a character, z. B. a positive and a subsequent negative or vice versa. The apparatus according to the invention is not only applicable to the Wheatstone system, but also to other systems in which signal currents come into use, which are transmitted at time intervals of a certain constant size or a multiple thereof will.

The invention particularly relates to receiving apparatus of the type in w ^r of the drive elchen for the punches and the strip feed is controlled by friction coupling elements which are arranged side by side on a uninterruptedly rotating shaft; two of these coupling members are used to actuate a punch each, namely one of these two coupling members is controlled by an electromagnetic device excited by the positive current pulses and the other by an electromagnetic device excited by negative current pulses, so that these coupling members when excited the associated electromagnetic device come into operation. A third coupling element regulates the feeding of the stiffener.

In such receiving apparatus it is known to be mutually dependent To arrange coupling links to control the punches, with the help of a device, through which the strip feed comes into operation upon receipt of a signal, while the third coupling element is controlled by one of the two coupling elements controlling the punching and is only used to control the To operate the tape feeder so that the space between the words and sentences are generated when the other coupling links are not in function.

The purpose of the present invention is now to provide a simple and reliable one To create apparatus of this type, in which the individual parts for the purpose of repair or renewal are easily accessible.

According to the invention, two are independent of one another in the new receiving apparatus Coupling members are provided which control the punches without the tape feed mechanism to influence. The latter is driven exclusively by the third coupling member, which only during the punching process of the strip by one of the punching punches Facility is paused.

According to the invention, the coupling members which actuate the punch have in this case the shape of coil springs surrounding the shaft which tend to rotate with the shaft; these coil springs have a stop at one end and a catch at the other end. The stops are normal with a engaged by the stop member controlled by the electromagnetic devices. the Latches control the punch in such a way that the coupling members are engaged by the engagement their attacks are held with the stop organs, but are attached to the shaft clamp and rotate with the same when caused by the arrival of a current pulse released by the stop levers. , The third coupling element for the strip feed is designed similar to the two coupling members controlling the punch.

The drawing shows an embodiment of the subject matter of the invention. Fig. Ι is a section along the line AA from Fig. 2.

Fig. 2 shows a view of the apparatus from above.

Fig. 3 is a partial section along the line BB of Fig. 2 and mainly shows one of the punching devices.

Fig. 4 shows the apparatus in a side view; the mechanism for "punching and for feeding in the strip is to be thought of as removed.

Fig. S illustrates part of the perforated strip.

Fig. 6 is a partial section along the line CC of Fig. 2.

In the drawing, 1 is the main shaft continuously rotated by a driving force denotes which is supported at its ends by suitable bearings 2, 2. On the Shaft ι sit in sequence, the three coupling members 3, 4 and 5. The coupling member 3 causes the punching of a number of Holes in the strip and the coupling member 4 punching the other row of Perforations, which are on the other side of the center line of the strip, which with is provided at the same distance from each other supply holes. That third coupling member 5 is used to regulate the strip feed.

The coupling member 3 consists of a spiral spring 6 wound onto the shaft 1 a stop or projection 7 is attached to one end of this spiral spring. At the the other end of the spiral spring 6 is provided with two lugs 8 and 9, which are mutually are offset. The second coupling member 4 is correct in construction and mode of operation with the coupling member 3 coincide. It is

with adjacent lugs 8 "and 9 ^s and a stop j ^a , namely these lugs 8 ^a and g" are offset from the lugs 8 and 9 of the coupling member 3 by 180 °, while the lugs 8, 9 and 8 ^a , 9 ° of both coupling parts 3, 4 side by side and the stops 7 and 7 ^{a of the} same are away from each other. Between the abutting ends of the coupling members 3 and 4, a plate g ^{b is} arranged, which keeps the two members at suitable distances from one another. The third coupling link S is similar to links 3 and 4. It shows a stop J ^b , but only a lug 12. These coupling members act in such a way that they normally rotate with the shaft as a result of the frictional resistance present between the springs and the shaft. If, as explained below, the approaches 7 or 7 ^e or J ^b interact with other stop parts or pawls, the spring windings are slightly lifted off the shaft r and thereby the frictional resistance between the springs and the shaft is reduced, so that the springs against the as the shaft continues to rotate. Conversely, a pressure exerted on the provided at the other spring end stops 8, ^8a, 9, 9 ° and 12 resistance (B. driving z. The punching), that the springs are more firmly tightened on the shaft, so that due to the order associated increase in frictional resistance, sliding of the springs relative to the shaft cannot occur.

The stop 7 of the coupling member 3 is normally in engagement with one end (arm) of a stop member or double lever 13, which is rotatably mounted at 13 ° and carries an armature 15 on the other arm, which is controlled by an electromagnet 17, which by the negative display or recording pulses are energized. The stop J ^{a of} the other registering coupling member 4 engages in the same way with a stop member or double lever 14 which carries an armature r6 which is controlled by an electromagnet iS (Fig. 2) excited by the positive display pulses. The stop members 13, 14 are under the influence of springs 13 ⁶ , which strive to keep them in the engagement or stop position. The lugs 8, 8 ^a each control a two-armed rocking lever 20 or 21 by acting on the arms 20 ″, 20 ^{6 of} the levers and thereby giving them a reciprocating movement. Each of the levers 20, 21 is on its own axis 55 and 55, ^a fixed (Fig. 2, 3) which are supported by a bearing piece 53. each of the two Schwinghebet 20, 21 controls a punch for piercing the strip 51. for this purpose, on one arm 20 ^s of each oscillating lever a respective Punch 23, 24 removably attached, which work through bores in the bearing piece 53.

The strip 51 is fed by means of a suitable feed wheel 28, which engages in the feed holes provided in the center thereof. The stripe 51 runs in front of the punches between two thin plates 54 and the surface of the bearing piece 53 through and from there onto the feed wheel 28 on.

The lugs 8 and 8 ^a generate through their action on the arms 20 ^s , ^{20 &} the desired back and forth movement of the punch, such that with one revolution of the shaft 1, the punch punctures the strip once.

The other lugs 9, ψ both act on one end of a double lever 30 rotatably mounted at 36 (Fig. 4), which engages with the stop y ^{b of} the feed coupling member 5 by means of an intermediate member mentioned later in such a way that the coupling member S is locked ( stopped) so that the strip is not fed during the punching process. g ₀

The catch 12 of the aforementioned feed coupling member 5 controls a two-armed rocking lever 31 which is rotatably mounted at 32 is and carries a spring-influenced pawl 33 which cooperates with a ratchet wheel 34, which is attached to the axle 35 carrying the feed wheel 28. (Fig. 1). Around achieving that the ratchet 34 is rotated only one tooth at a time is an adjustable one Stop 60 is provided, d. H. the strip (51) becomes the Wave ι guided forward by the distance of a feed perforation.

The lever 30 is at one end with the lugs 9, g ^a in engagement and is set in vibration by both lugs. This lever end (arm) is held in engagement with the two lugs 9, g ^a (FIG. 4) by a spring 37 which is enclosed in a bearing part 38. The other end (arm) of the lever 30 engages in the slot of a stop element 39 which is arranged displaceably in a bearing part 40.

Before the arrival of a current pulse, the stop element 39 is in the position shown in AbK 4 position shown, d. H. out of engagement with the stop part 7 *, so that the strip feed can go on. After receiving a current pulse, the coupling member 4 or 3 rotates and presses the right one Lever arm of the rotary lever 30 against the

Action of the spring 37 'by means of the catch 9 or 9 ^a downwards, so that the stop member 39 seated on the left lever member is lifted ^{into the path of the stop member 7 6.} As a result, the coupling member 5 and thus the strip feed effecting stop 12, which works in the aforementioned manner on the two-armed rocking lever 31, is stopped, ie it does not follow the rotation of the shaft ι for the time of the engagement of the stop part 7 ⁶ with the stop member 39 more. The arrangement of the lugs 8 or 8 ° and the lugs 9 and 9 ^a on the shaft ι is here such that the engagement of the lugs 9 and 9 ⁰ with the right lever arm of the lever 30 occurs, d, h. the stop of the strip takes place a certain time before the start of the engagement of the lug 8 or 8 ° with the lever 20 °, so that the Streiao fen is already at a standstill at the start of the punching process. The release of the right lever arm 30 by the catch 9 or ψ also takes place a certain time after the release of the lever 20 ^s by the catch 8 or 8 ^a , ie after completion of the punching process (see Fig. 3 and 6).

Instead of one stop part J ^b , two or more stop parts seated one behind the other can also be arranged so that if the front one passes the stop part 39, the next one will strike against the stop element 39.

During operation, the shaft 1, as is usual with such devices, is driven at a slightly higher speed than the corresponding shaft of the transmission device (not illustrated) at the feed station, so that the coupling members 3, 4, 5 have time to return to their starting position before the next signal arrives. The coupling part 5 rotates with the shaft 1 when the shaft 1 rotates, and as a result the feed wheel 28 for the strip is driven from the catch 12 through the intermediary of the parts 31, 33, 34, 35. The recording (punching) coupling members 3, 4 are normally held by the engagement of their stops 7, 7 " with the associated stop members (double levers) 13, 14; however, if one of the electromagnets 17, 18 is caused by a current pulse from the feeding station, namely either a positive or negative current pulse, excited, the armature in question 15 or 16 is attracted and thereby triggered the stop member, so that the associated coupling member is free and immediately rotates with the shaft ι.

In the further course of the supply coupling member 5 regulating lever 30 is rotated by the corresponding lug 9 or g ^{a of} the relevant recording coupling member, whereby the stop member 39 is lifted into the path of the stop 7 ^b , so that if the position of the coupling member 5 such is that the strip feed and punching process take place simultaneously, the stop member 39 pushes against the stop 7 *, whereby the coupling member 5 is held and so the strip feed is interrupted. Then the associated punch control lever 20 or 21 is moved by the corresponding lug 8 or 8 ″ of the coupling member 3 or 4, so that this punch pierces the strip 51 and then returns to its original position. As soon as the punching process has ended, the feed coupling member 5 is released from its stop member 39, so that the strip feed is continued.

Figure 5 illustrates a piece of one used in the apparatus Strip. This strip has a middle row of feed holes 62, with which the feed wheel 28 engages. The strip piece is for example ; shown in such a way that it is pierced with a dot and a dashed signal, ■ which together represent the letter »α«. The punched holes on both Sides of the middle row of holes 62 denote the Wheatstone signals in the usual way, which are formed in a known manner by a point and a line. The holes above the holes 62 are by positive and the holes below the perforations 62 by negative current pulses manufactured.

In the case of a point signal, the holes are in one with the feed hole in question Line, d. h, vertically one below the other (see 63, 65 Fig. 5), with a line signal this is hole formed by the negative current pulse in line with that feed hole, which follows the associated hole produced by the positive current pulse, such as is illustrated in Fig. 5 by 64, 66 so that each letter element consists of a Positive pulse hole on one side and a corresponding feed hole and a negative pulse hole on the other side of this feed hole. The holes are punched one after the other. The first current pulse is a positive one, so that by energizing the electromagnet 18, the corresponding rod 24 opens the hole 63 punches. Then the negative current pulse follows, causing the hole 65 by the excitation of the electromagnet 17 and the other punch 23 is formed. While of punching these holes 63,65, the tape feed, if necessary, is done in advance

In the manner described, the lugs 9, 9 ⁰ successively depress the lever 30 at its "end, so that the link 39 is raised into engagement with the stop part y ^b . The strip 31 is then continued and when the negative current pulse corresponding to the line arrives the hole 66 made by the appropriate punch.

In order to enable a safe return of the stop members 13, 14 formed by the armature lever to their initial position for the purpose of engaging the same with the stops 7, J ^a after each rotation independently of the spring I3 ^{ft ,} an arm 57 is seated on each of the axes 55, 55 a which runs over the engagement ends of the levers 13, 14.

When the coupling members 3 or 4 are rotated, the relevant

ao arm 57 through the axis 55 or 55 ″ rotated by the rocker arm 20 or 21, on which the same sits, is lowered so that the stop lever 13 or 14 by this arm 57 in its original position of engagement becomes and thereby to the engagement or stop with the stop part 7 or 7 ° is ready. To prevent damage to the mechanism, which as a result is inaccurate Cooperation of the arms 57 with the stop members 13, 14 caused could be, these arms 57 are resiliently arranged, for example in that they sit loosely on their axes 55> 55 ", but from the side by springs 59 are pressed into frictional engagement with sleeves or the like attached to the axles. The arms 57 can be on their Axes by adjusting screws that act on the same in the bearing part 53 from above 58 can be adjusted in their angular position.
