Remote start-stop printer

Patented in the German Reich on September 26, 1931 Patent granted April 15, 1943

There are already start-stop remote printers with typewriter keyboard for the five-letter alphabet or similar telegraphic alphabets known in which to effect the Pressing, the tape feed and the like on the ring-shaped selection rails of the receiver dial provided gaps are set to an open longitudinal groove by the impulses coming from the transmitter of the other station and in this groove that effect the printer and the tape feed Organ invades.

It is also known to supply these annular selector rails from an adjusting pin drum actuate, which consists of axially displaceable adjusting pins, their thumbs or fingers are arranged on a straight generating line of the drum and when performing a full revolution of the latter in this way

ao be set so that they can make the relevant adjustment of the dialing modes for education allow an open longitudinal groove. This leads to some known apparatus of this type the adjusting pin drum a continuous rotary movement by distributing the adjusting pins not over the whole, but about half the circumference of the drum, with the others, on the other hand, the S part of the pen drum does not move continuously, but step by step turns.

In all known remote printers of this type, all of the five, Six or the like alphabet required gaps from which the relevant longitudinal grooves are formed for both characters and operating combinations, usually only on one, e.g. B. distributed outer Sedte of the annular selection rails. Consequently the circular path of the viewfinder is very large and therefore requires greater accelerations, by the uninterrupted rotation of the type wheel, the movement or rotation of the ring-shaped selector rails, and other with the same working parts required, whereby the construction of the apparatus is extraordinary gets complicated. In addition, the maximum number of such remote printers for the selected five, six or other alphabet possible combinations not fully used.

A not inconsiderable disadvantage of these known devices is also the fact that that, as already mentioned, the adjusting pins the same the selector rails not directly, but Operate with the help of various intermediate organs.

All of these disadvantages make the construction of such remote printing apparatus' very complicated at the same time necessitate an increased rotational speed of the adjusting pin drum and other parts, whereby the wear of the working parts increases and the assembly of the individual parts as a result the indispensable precise adjustment and increase in the number of them is made more difficult.

On the contrary, the purpose of the present invention is to cover all moving parts

to run around without accelerations if possible and where the accelerations it is inevitable to keep the mass of the moving parts as low as possible. to For this purpose, the adjusting pin drum is designed in such a way that its adjusting pins are uniform are distributed over the entire circumference, so that the formation of the combinations temporally distributed over the entire revolution ίο of the drum and at the same time by means of the adjusting pin fingers arranged in a line of the drum circumference Transfer of these formed combinations to the ring-shaped selector rails by direct actuation of the same by the Adjusting pin fingers without any intermediate connection Auxiliary organs is effected. The ring-shaped selection rails are also used to reduce the circular path of the Viewfinder and to reduce the mass of the selector rails themselves designed in such a way that on its one, appropriately inner side, only the gaps for the formation of the open longitudinal grooves of the character combinations are distributed, while the gaps for the formation of the operating combinations corresponding open longitudinal grooves, into which the associated levers fall, on the other, possibly outer Side of the selector rails are provided. Such an arrangement still has the important one Advantage over the known constructions that with the selected z. B. Five-letter alphabet exploits the largest number of possible combinations and that on the other hand any number of Character groups or registers can be obtained without doing any essential There is a reduction in the number of possible combinations.

In accordance with the general " Principle of rotating all rotating masses without accelerations if possible and where it cannot be achieved Keeping the masses to be accelerated as small as possible is also the task of the seeker, at the same time, with the continuously rotating adjusting pin drum and the type wheel, a continuous Rotation communicated. It falls into the self forming, the respective character combination corresponding open longitudinal groove only a part of the viewfinder, the bar 65, whose mass is, of course, nowhere near as great as the Is the mass of the continuously rotating viewfinder.

Throughout the apparatus of the present invention, the principle is direct Acting of the organs fulfilling the end functions carried out consistently, and although -im. In contrast to the well-known remote printers, in which those recorded in the receiver Impulses only release the locking devices of the relevant intermediate organs, which then bring about the actual activity of the organs fulfilling the end functions. The setting of the stylus pens concerned themselves is carried out in accordance with the present invention by means of a position in front of the setting pins under the action of the receiving electromagnet lumbar beveled, crooked curses causes what makes the setting special is made selective.

Because of the small amount of work required, there is no strong friction clutch required, and there is no risk of the slipping due to the weak load Clutch in front.

As a result of all of these advantages, the remote printer is in accordance with the present invention ■ all known remote start-stop printing far superior to this kind.

Another advantage of the present remote printer is the fact that! according to an embodiment of the invention during the formation of a combination the armature of the receiving selector remains unloaded, but this is not the case in any of the to now known start-stop remote pushbuttons the case is.

In the accompanying drawing is an exemplary embodiment of the present invention Invention shown schematically, namely shows

Fig. Ι the floor plan of the type printing apparatus,

Fig. 2 is a side view of the transmitter, Fig. 3 shows the transmitter setup, Fig. 4 the receiver device, Fig. 5 the basic »oo belonging to Fig. 1 tore the keyboard,

Fig. 6 to 10 different parts of the remote printer.

The keyboard of the present remote printer (Fig. 5) has 46 distributed in four rows Keys, five of which are used as operating keys and the rest for digits, characters and Letters of one or two different alphabets can serve.

The keyboard of the remote printer does not require any particular precision during manufacture. If necessary, no special design of the selector rails is required, since the effective Part of the same under the key as an ordinary rail without any recesses can be executed.

Is yet for any conversion of characters to telegraphic characters no shifting of the rail is necessary, it has a simple straight line 12 » saving (milled or punched), the width and depth of which corresponds to the width and stroke height of the key

lever corresponds and a simple manufacture required in one operation.

The selection rails 9 (Fig. 3) are moved downwards and sideways by pressing the buttons. The angle of inclination and the length of the slots 3 sliding along immovable pins are determined by the size of the. Lateral shift (to the right) of the selector rails and the stroke height of the buttons are determined. The selector rails 9 move the double-armed levers 5 with their sideways movement, the other arms of which switch off the contacts 4 of the circuit breaker, and then return (when the buttons are released) under the action of the springs 15 and 5 ^{a back} to their starting position, while the double-armed levers' 5 remain locked in their working position by the pawl 8 until the end of the broadcast of the characters in question until they are released by the lever 20 through the intermediary of the rod 21 and returned to their original position by the action of the springs 5 ^a .

In addition to the selection rails, there are also three operating rails, one of which also has inclined slots 3 and the other two longitudinal slots 10. The first operating bar, which is actuated by each key, is used for putting into operation, the other for closing the numbers and letters when switching to other fields and the third for closing all keys while a telegraphic symbol is being sent. ■ For better handling

35. on-site use, when assembling, replacing individual parts and making repairs the entire housing 2 is fastened by four screws and can therefore be easily removed, as well as every electoral rail.

Each key can be removed just as easily as it is only guided in a comb and is only held in place by springs hooked into its end (Fig. 2).

The circuit breaker 13 (Fig. 3) consists of five spring contacts isolated from one another, which in their rest position with a common plate by soldered silver attachments 4 in contact stand. At the ends of these spring contacts, insulated pins are attached that the face the upper arms of the double-armed lever 5 actuated by the selector rails 9. The electrical conductors of the circuit are soldered to the other ends of the contact springs. The silver is here only Chosen to protect against oxidation, since the contacts 4 are neither closed when energized can still be opened.

The transmitter (Fig. 3) consists of a power distributor 12 with a circulating Abrasive brush 17, which stops after each revolution on the stop contact 13 ″.

The power distributor 12 consists of five character contacts for sending the telegraphy characters. Each sign contact comprises 51 ⁰ and is separated from the others by an insulating layer of 9 ^{0 each.}

In addition to these five character contacts, the power distributor also has a stop contact 13 "of 24 ⁰ and a start insulation strip of 36 ⁰ (insulation).

In the direction of rotation of the grinding brush, the contacts have "an order such that first the stop contact, then the start insulation and finally the drawing contacts are coated by the grinding brush. The rotation of the grinding brush 17 over the power distributor 12 is effected by pressing the button on its selector bar 9 moves to the right and deflects the relevant double-armed lever 5, which presses the rod 22 with its other arm, thereby deflecting the lever 24 via the lever 6 and thus releasing the arm 16 of the brush holder ιγ ^α.

The brush holder 17 ° is insulated and through a slip clutch · with a 'continuously rotating Shaft 19 connected (Fig. 3 and 1).

The arm 16, which is firmly connected to the brush holder 17 ^a via a sleeve, pushes the start lever 20 back at the end of the cycle after the telegraphy sign has been sent before the stop position Telegraph sign triggers.

If the worker has failed to release the button until the end of the brush cycle, the grinding brush is still switched off, since the brush holder is only released when the button is pressed and not for the entire duration that the button remains pressed. This is achieved in that the rod 22, when pressed against the lever 6, at the same time rests with its beveled back against a guide pin and slides down under the same. The lever 24 releases the arm 16 of the brush holder 17 ″ , but returns to the stop position. To continue the rotation of the brush holder, the rod 22 must first be returned to its starting position and actuated again, ie the button must be released and pressed again .

The rod 22, the stop lever 24 and the start lever 6 are under the action of their Coil springs. These springs cause levers 6 and 24 to engage and seek to bring the rod 22 into its rest position. The power distributor, the brush holder and the Starter devices are attached to the front outside of the frame of the remote printer.

organizes and is therefore easily accessible. The brush holder iy "is compared to the shaft and the sleeve, on which it _sits;?. Electrically insulated and is only connected with the sliding of the ßürstenhalterring spring which i at the contact screw ^h, conductively connected to the mark contacts 12 are connected to the contacts 4 of the circuit breaker and the stop contact 12 ″ connected to the common plate 13, which is isolated from the frame and with which the contacts 4 are conductively connected in their rest position via the soldered-on silver parts. The contact screw \ y ^a of the brush holder is connected to the remote printer arranged milliammeter to the right on the side of the front frame.

The receiver of the apparatus (Fig. 4) consists of an ordinary electromagnet 26 with a spool attached to the inner stand 25 of the remote printer. The iron core of the electromagnet is composed of divided transformer iron and has a U-shape, over the poles of which the armature 27 is made of one whole Iron piece arranged. The armature lever 28 is rotatable with one end on an axis attached, the other has a neck with an inclined surface 28 ", which during the Current interruption when removing the armature from the magnetic poles under the adjustable Spring action is articulated upwards and the adjusting pins 31 ″ of the circumferential Wähverks 31 (Fig. 1, 4, 9 and 10) free lets through. The electromagnet J has e.g. B. the following characteristic: diameter of the Winding wire (without insulation) 0.12mm, Number of turns 4500, resistance 500 Ohm, self-induction 5 to 6 Henry.

The anchor deflection is adjustable. In addition to its own movement, the anchor causes also the release of the drum 31 of the voter by the double-armed lever 29 and the angle lever 30 (Fig. 4). The angle lever 30 is supported against the armature lever 28, but it is exposed during the conversion of the telegraphic characters into written characters.

The A-angle lever 30 (Fig. 4) rests on the one hand against the armature lever 28. on the other hand he supports the bent end of the double-armed lever 29 in a projection. This lever arm of the angle lever 30 has a second securing projection.

Fiat the armature lever 28 the drum 31 of the Wähl'verks triggered by means of the angle lever 30 and the double-armed lever 29, see above it can be raised or lowered freely while the A-angle lever 30 is in its position through the double-armed lever 20. until the end of the compilation of the telegraphic symbol remains locked by the fact that his left arm is out of the recess the drum 31 exits and on its outer circumference up to the full revolution slides.

The selector mechanism (Fig. 1, 4, 9 and 10) consists of a drum 31 with the adjusting pins 31 "and the housing $ 7 with the circular selector rails 40". The drum 31 is freely arranged on the same shaft 19 on which the brush holder of this transmitter is located. The sleeve of the drum, however, is -erbunden with the shaft 19 by a slip clutch i8 ^a similar to the brush holder with a ratchet and pawl \. The drum 31 has five lock pins 31 "with limited Verscliiebbarkeit in the axial direction, and a guide for the fingers 31 ⁶ all the adjusting pins. ■ The positioning pins are located at the head of the drum 31 face against each other adjusted to 6o °. The fingers 31 * of the adjusting pins 3 i ^a , however, lie on a surface line and are evenly spaced along the length of the drum.They can be moved from the working position to the rest position by 1.2 to 1.4 mm.

During rotation of the drum 31, the one ends abut the positioning pins 31 "against the curved surface of the strip 44 (Fig. 1) and are brought into their initial position. With go the further circulation they come from the other side of the inclined surface 28 ^s of the Approach of the armature lever 28 and are brought into the working position with the armature tightened and left in their position with the armature dropped, whereby the required assembly of the adjusting pins is effected during one full revolution of the drum 31, depending on the telegraphic signal transmitted. ■>

This position of the adjusting pins is when rotating, the drum 31 on the lugs 40 of the Transfer levers of the circular selector rails 40 ″ of the selector, thereby deflecting each Vsc of the circle can be rotated. After expiration the drum 31 falls the double Lever 29 with its end in the recess of the drum 31 of the Wähhverks and brings this to a standstill.

The circular selector rails 40 "(Fig. 61 11 ο of the selector are housed in a housing 37. On the inner circumference of this Rings are the gaps for the character selection, on the outer one the gaps for switching (numbers, letters, etc.) cut out.

The cover 39 of the housing 2> 7 is provided with recesses on the inside opposite each possible setting (28 recesses over the entire circumference). The cover is thick-walled, hardened and absorbs all the impacts of the collapsing member 37 *,

Claims (1)

making the circular selector rails 40 ° be spared. For this reason, the selector rails can be made of unhardened steel getting produced. The circular selector rails 40 ″ are provided with levers 40 (Fig. 10) which are actuated ^{by the fingers 31 6 of} the adjusting pins 3 i ^{a when the drum 31 is rotated} 6.5 °, ie urn ¹ I ₅₆ of the TJmfanges, under the action of the fingers 31 of the positioning pins 31 ° with respect to a continuous longitudinal groove in all five Wählschienen • 5 a certain recess of the cover 39. To determine the circular selector rails 4o ^a in such an assembled position, they are blocked by a bar 45 (Fig. 2), which through the slot in the drum 37 into the recess on the outside of each of the circular selection rails falls into it. If a certain longitudinal groove within the circular selector rails 40 ^a is now open, they only return to their rest position after the bar 65 of the viewfinder 37 ° has collapsed (Fig. 6) and the release lever 50 (Fig. 3) has been actuated. The triggered circular selector rails 40 ° return to their starting position under the pressure of the coil springs 51 (Fig. 10). But if there is a longitudinal groove on the outside of the adjusting rings (operating or circuit symbols) opened, the triggering of the circular selector rails 40 ″ during the Changeover by the release lever 50 ° by means of a stop on the release lever 50 causes (Fig. 3). Inside the housing 37 (Fig. 6) the adjusting member 37 ^a (Fig. 7, 8) is attached to the shaft 32 of the type wheel, which slides with its bar 65 on the inner circumference of the adjusting rings. As soon as the adjusting member has hit an open longitudinal groove, its bar 65 falls into the same under the action of a spring, and the entire movable part 66 of the adjusting member stops. On the other hand, its part 67 fastened on the axis 32 continues its rotary movement, pushes the sleeve 37 * with the help of inclined surfaces which are arranged on the movable part 66 and pulls the bar of the adjusting member out through the intermediary of the rods 66 "and 67 ° As soon as the bar 65 has left the recesses in the circular selection rails 40 ^ß , the movable part 66 overtakes the rotating part 67 of the adjusting member under the action of the operator. The sleeve 2> ^7b pushed back by the beveled point of the part 66 presses the angle lever ^ 9 (Fig. 3, 8), the other arm of which triggers the release lever (Fig. 2) of the ring lock, and actuates the pressure hammer 38, throwing it upwards and causes the hammer to strike the tape, whereby the relevant character of the type wheel is printed on the tape. ·· Have the angle lever 59, the sleeve ^3/6, the Einfaljglfed 37 "and done their work to the pressure lifting ^ S (Fig. 3), and they are returned under spring action in the rest position, the tape by the decrease of the tape drawing lever 60 is under the action of the coil spring 6o ^e advanced (Fig. 3). The mass of the drum is about 23 to 25 g, its diameter about 20 mm. The mass sizes and dimensions of the remaining rotating and stationary ones Transmitter parts have roughly the same values. These variables characterize the stop-start system of the remote printer and determine the solution to the technical problem with regard to the strength and wear and tear of these individual parts. The other parts are either immobile or rotate continuously at a constant speed the end. It should also be noted that the stop-start parts are not suddenly switched off, but happens gradually by sliding, which instead of a sharp jolt occurs quiet noiseless parking is effected. This is due to the shape of the cutouts achieved in the relevant locking parts. The adjustment element (Fig. 6) fulfills the following task: The selection of the by the converter prepared characters, printing, automatic switching of the type series (including alphabets) and the Advance of the tape. The automatic switching of letters to numbers or one alphabet also the other is effected in the following way: The type wheel 34 (Fig. 1) is with its hub in the longitudinal direction on its shaft 32 by means of a wedge-groove connection ver xio sliding. The hub has a groove in which the pin of the fork of the switching lever 61 intervene. The other arm of the lever is articulated with a point of the Washer 56? tied together. The rotary movement of this disk causes an oscillating movement of the lever 61, the fork of which adjusts the type wheel 34 along its axis 32. The type wheel has three series of different types, e.g. B. Latin letters, numbers, Russian Letters 0. The like. Which by appropriate rotation of the disk 56 "in the
