RECORDING MACHINE Filed May 14, 1938 arr/mm 15 a mvzgm ATTORNEY Patented Oct. 8, 1940 arms RECORDING MACHINE- Application May 14, 1938, Serial No. 207,976

9 Claims.

This case relates to automatic writing or data transcribing machines. 1

One of theproblems in the use of a typewriter or the like for transcribing coded designations, 5 such as, for example, derived from a record sheet, is to maintain a substantially even right hand margin on the sheet receiving the transcription. This is particularly the case when provision must be made for interposing or inserting data within the data derived from the coded designations. Suchinterposed data, for example, may be a manual insertion to be made by the operator. As is known in the art, the record sheet is perforated with the data, known as form data, to control the writing of a plurality of form letters or statements. These form letters may be individualized by inserting or interposing different cities or names within the form data. To enable the insertion to be made, the perforated record usually is provided with a code which interrupts the automatic control of the typewriter. The

operator is then enabled to interpose the manual insertion orvariable data, following which the operator initiates the resumption of operation of the record sheet'to complete its control of the typewriter.

It is apparent that, while the form matter does not differ in length, the manual insertions for different letters may be of considerably different lengths. If the carriage return operation is fixedly controlled by the record sheet to occur at the end of preselected words or characters of the form matter, the manual insertion, being 0 interposed between the automatic reading out of the record designations, may cause the automatic carriage return operations to take place at indeterminable, variable points of the travel of the typewriter carriage so as to result in an uneven or ragged right hand margin.

Furthermore, the body of the form letter may include only one form paragraph or may include a plurality of form paragraphs. In order to present a neat and symmetrical appearance with 15 respect to the length of the letter sheet, the body of the letter should be of substantially the same length irrespective of the number of paragraphs to be written. When only one form paragraph is to comprise the body of the letter, then this paragraph should occupy a greater length than when the same paragraph is to be used in conjunction withone or more other form paragraphs. Previously, the number of lines of typewritten form matter, and, consequently, the length of the form matter has been predetermined by the location of the carriage return codes on the record sheet, so that whether one or more paragraphs were to be transcribed, there was no possibility of varying the length of any paragraph.

The general object of the present invention is to overcome the difiiculties presented in the prior art due to the fixing of the length of form matter and the marginal position of such matter by predetermined codes on the record or control sheet.

Further, an object is to cause the automatic transcribing apparatus to prepare a letter or statement, or paper, including both form matter, derived from codes, and interposed matter, such as, for example, a manual insertion, with a substantially even right hand margin regardless of variation in the interposed matter. 1

It is also an object to provide means for selectively transcribing or not transcribing or trans mitting the control of a sensed coded designation.

More specifically, it is intended to provide means for optionally recording or printing or not printing a character designated by a sensed code.

It is also an object to optionally divide or not divide a word at the end of the line; i. e-., to print either the entire word or a syllable or syllables thereof, printing the rest ofthe word on the next line.

Further objects of the instant invention reside in any novel feature of construction or operation or novel combination of parts present in the embodiment of the invention described and shown in the accompanying drawing whether within or without the scope of the appended claims and irrespective of other specific statements as to the scope of the invention contained herein.

In the drawing, the figure is a diagrammatic showing of the transcribing apparatus and control therefor, and including the circuit connections.

The invention is applicable to any known system of transcribing coded designations, whether received or read out from a record card or sheet, through wireless, or an electrical or pneumatic circuit, and to any known system of sensing the coded designations, whether electrical or pneumatic, and to any'suitable transcribing, writing, or typing apparatus.

For the purposes of the disclosure, the invention is described and shown herein in connection with electrical means for sensing the codes or designations on a record sheet l0, each character or function being represented by a single hole code along the width of the sheet.

The typewriter carriage and platen are diagrammatically indicated by H, and a fixed rail of the typewriter is represented by 12. The adjustable right hand margin stop of the typewriter is designated by 13. The typewriter keys are designated by common reference number N, and only the space, carriage return, and hyphen keys are shown. The keys I4 may be manually operated or automatically operated by magnets or solenoids l5 operatively connected to the keys. Any suitable automatic carriage return mechanism may be operated by the carriage return key, such as disclosed, for example, in Patent 1,955,614.

The right hand margin stop I3 is adjusted in accordance with the approximate desired width of right hand margin. A circuit connection is made to a conductive part of stop 13 and the conductive part rides along the fixed rail 12 as the carriage spaces to the left. Set in the rail 52 is a conductive strip 16 to be wiped by the stop l3 as the carriage reaches a right hand margin zone. The length of this zone is fixed by the length of strip 16, but the location of the zone with respect to the travel of the carriage is variable and depends on the adjustment of stop l3.

Record sheet l0 moves, during its control of the typewriter, in the direction indicated by the arrow, from one roll I! to another roll l8. The shaft of roll i8 is connected to a clutch disk 19 to be coupled to a drive clutch disk 20 when the clutch lever 2| is rocked clockwise by energization of a clutch magnet 22.

Intermediate rolls l7 and i8 is a contact roller 23 over which. the sheet l0 passes. Sensing brushes 24 are provided, one for each designation position along the width of the sheet, but only the brushes necessary to explain the present invention are shown in the drawing. A common brush 2 3 is also provided to constantly wipe the bare surfaces of the contact roller. When a designation brush senses a perforation, it closes a sensing or analyzing circuit to effect control operations, in a manner which will be explained further on.

Sheet may bear the data for a single paragraph or for a plurality of paragraphs. When a plurality of form paragraphs are provided on sheet ll), suitable means are utilized to select the paragraph or paragraphs to be transcribed. The conventional interpretation of the perforations and the paragraph codes may be indicated on sheet in so that any desired paragraph may be manually selected.

To start operations, the operator depresses the start key, establishing the following circuit:

Start key circuit.From the right side of the line, through start key contacts ST, relay magnet 25, to the left side of the line.

Magnet 25 closes relay contacts 25a and 25b. The closure of contacts 25a shunts the start key contacts ST, and establishes the following holding circuit:

Start holding, circuit.From the left side, through coil 25, contacts 25a, normally closed relay contacts 26a, normally closed contacts 21a, stop key contacts SK, to the right side.

The closure of contacts 25b establishes the clutch magnet circuit as follows:

Clutch circuit.-From the left side, through safety or interlock contacts 28, relay contacts 251), and clutch magnet 22, to the right side.

Clutch magnet 22 now couples clutch disk to drive clutch disk l9, causing roll l8 to rotate and feed record sheet In.

According to the present invention, the carriage return or line space, and consequently, the right hand margin, may be under control not only of the usual carriage return code, but also under selective control of one or more other selected codes. The latter codes may be referred to as the selective line space control codes or as the special, or optional, or supplementary line space or carriage return codes. The special codes include the word space or intraline space code, the normal hyphen code,.and the optional hyphen code. The normal hyphen code is used in hyphenating words, such as anti-aircraft. The optional hyphen code is used in separating syllables of a word.

In preparing a record sheet H) to utilize the supplementary carriage return codes, the form matter to be perforated in the tape is first written out for the guidance of the punch operator, with indications for the insertion of the optional hyphen codes. An example of form matter on a guide sheet given to the punch operator is as follows:

Replying to your request, we are sending a price list and de-scrip-tion of the part of our stock. in which you will proba-bly be most inter-est-ed. In this se-lec-tion we hope you will find an arti-cle which will satis-facto-ri-ly meet your re-quire-ments for pre war stamps.(C.R.)

The asterisk in parenthesis indicates the beginning of the paragraph, and the punch operator accordingly punches a carriage return code to insure the typewriter carriage returning from its previous position to the beginning of the next line. The next punching is of a tabulating code to effect a paragraph margin spacing. The letters, hyphens, and space codes are thenpunched as indicated. The single hyphen or dash between syllables of words indicates the punching of optional or special hyphen codes. The double dash or sign, as in pre=war indicates the punching of a normal hyphen code. The CR.

in parenthesis at the end of the paragraph indicates a carriage return code.

Having punched the above form matter in the record sheet, the latter is now delivered to the typewriting departmentto be transcribed. Before transcribing the illustrative form paragraph from the perforations in the record sheet, the operator sets the left hand margin stop (not shown) and the right hand margin stop 13. The wider the margins, the fewer are the num'- ber of characters and words which may be typed along one line. Thus, the form paragraph would occupy a greater number of lines as the width of the margin was increased. If the form paragraph is to be the entire body of the letter, the number of lines or the length of the paragraph should be sufficient to occupy a substantial portion of the length of the letter sheet. If the form paragraph is to be used in conjunction with other paragraphs to provide the body of the letter, the form paragraph should occupy a fewer number of lines and occupy a smaller portion of the length of the letter sheet. Accordingly, the operator preliminarily sets the margin stops in accordance with the number of lines or length of the sheet the form paragraph should occupy. The adjustment of the right hand margin stop, in conjunction with conductive strip l6, determines the location of the right hand margin zone, along any escapement step or point of which the special, supplementary, or optional carriage return codes become effective to cause a carriage return and incidental line spacing operation.

To illustrate the flexibility the machine in transcribing the same form matter with diiferent margins and different lengths, two examples of typing of the form matter previously described as on the guide sheet given to the punch operator and which has now been punched in coded form in the record sheet, are given below. For convenience in designating these examples, they are numbered (1) and (2) and to indicate the beginning of the right hand margin zone, colons are placed above and below each paragraph. It is to be understood, however, that neither the colons nor the designations (l) and (2) are actually typed. The examples follow:

Replying to your request, we are sending a price list and description of the part of our stock in which you will probably be most interested. ,In this selection we hope you will find an article which will satisfactorily meet your requirements of pro-war stamps.

' The operations performed by the transcribing apparatus will now be explained in connection with the above examples. In both examples, the first code sensed is a normal carriage return code.

The sensing of this code by brush 24-CR estab- Simultaneously with formation of the C. R.

code circuit, the following circuit is formed:

Relay coil 33.--Beginning as in the above circuit, to terminal 3I, then proceeding through line 34, through coil 33, and to the right side.

Energization of coil 33 closes relay contacts 33a, forming the following circuit: 1

C. R. stop circuit.--Beginning as in the preceding circuit, then from line 34 through line 35, relay contacts 33a, slow relay coil 26, and to the right side.

Energization of coil 26, after a slight lag, opens contacts 26a in the start holding circuit, thereby deenergizing relay coil 25 and causing contacts 251) in the clutch circuit to open and deenergize clutch magnet 22.' As a result, clutch disks I9 and 20 are uncoupled, causing the record sheet II] to stop feeding.

As a furtherresult of closure of relaycontacts 33a, the following circuit is formed:

Delay coil 36.-As in the preceding circuit, then, from contacts 3311, through delay coil 36, and to the right side.

Energization of coil 36, after a slight delay, effects closure of its relay contacts 36a. .Closure of contacts 36a forms the following circuit:

Delay coil 37.- rorn the side, through points 365a, and delay coil 3?, to right side.

Delay relay 3i is designed to close relay points 37a after an interval greater than the maximum length of time which the carriage may possibly take to return'to the beginning of the next line. Delay relay 36 is so designed as to make contacts 38a after a slight delay, but before the relay contacts 25b are permitted to open, for a reason which will appear later, and also to retard the opening of these contacts 36a for the maximum carriage return interval, so as to maintain a circuit through delay coil 3! long enough for the latter to close its relay points 31a at the end of the maximum carriage return interval. Thus, by the time contacts 31a have closed, the carriage has returned to the beginning of the next line; The closure of contacts 31a completes the following circuit:

Delay start circuit-From the left side of the line, through points 31a, relay coil '38, to the right side of the line.

Coil 36 now closes its relay points 38a, shunting the start key contacts ST, so as to close the circuit of coil 25 which, in turn, closes contacts 25a toform the holding circuit of the latter coil, and also closes contacts 25b to again energize the clutch magnet 22.. The record sheet I now resumes feeding.

The operation of the machine under control of the first carriage return code has been explained. .The next code is a tab code for controlling tabulating operation of the typewriter carriage to effect the paragraph margin spacing. The control of the typewriter by the tab and character codes is effected in the usual manner and need not be explained herein. When the carriage has not yet reached the right hand margin zone, the sensing of a word space code closes the following circuit:

Intermediate space circuit.From the left side, through contacts 28, relay contacts 25b, common brush 24, contact roller 23, the space code sensing brush Z I-SP, space line 39, normally closed relay contacts 400:, line H, through the space bar solenoid I5, and to the right side.

Energization of space solenoid I depresses the space bar to effect the normal intraline or word spacing operation of the carriage.

In Example (1), the right hand margin stop.

. I I3 has been adjusted to reach conductive strip I5 as the carriage escapes following the printing of the comma at the end of line 1. The carriage is then in the right hand margin zone, as indicated by the colons above and below the paragraph. Upon the margin stop I3 engaging strip I6, the following circuit forms:

Margin zone circuit-From the left side, through wire 42, through the stop I3, strip I6, and relay coil 40, to the right side. Coil 40 now opens contacts 40a'so that sensing of the intraline space code will not at this time form the intermediate space circuit. The carriage has now reached the right hand margin zone, coil 40 has been energized,

operation. Thus, as a result of the sensing of the space code when the carriage is in the right hand zone, intraline spacing is suppressed, and, instead, a carriage return operation is effected. It is clear now that the space code is one of the optional carriage return codes. Just as in the previously described carriage return operation, coil 33 is energized to close points 33a which, in turn, close the C. R. stop circuit, through coil 26 to interrupt operation of the record feeding means.

Also, the closing of points 33:; energizes delay coil 86 to close points 35a which remain closed for energizing delay coil to make contacts (ila after the carriage return interval so as to restart, then, the feeding of the record tape.

In above manner under control of the right hand margin zone determining means, the intralast word price of line line space code, instead of effecting the normal intraline spacing, has caused a carriage return operation after the comma at the end of illustrative paragraph (1). For Example (2), the right hand stop l3 has been set to begin the right hand margin zone at the letter e in the Thus, the operations described above as occurring upon the sensing of an intraline space code following the comma at the end of line i of Ezamp e (i) take place in regard to paragraph (2) only after the typing of the word price, line 1.

The typewriter, under control of the record sheet, types the second line of paragraph (1), and at the end of this line, another space code effects carriage return operation. The same thing occurs at the end of lines 3, 4 and 6 of paragraph (1). In typing line 5 of the latter paragraph, the carriage reaches the right hand margin zone immediately after typing the syllable se at the end of the line, and at this point, the brush E l-OH is sensing an optional hyphen code. In the absence of the optional hyphen code, the next code on the record tape Ill would be the letter Z followed by codes for the remainder of the word selection. The carriage would then return only after the entire word selection had been completely typed in the fifth line. As a result, the word .selection" would extend a considerable distance to the right of the terminal words of the other lines, rendering the right hand margin extremely uneven. In order to avoid this unevenness of margin, syllabification is utilized, with the special optional hyphen codes separating the coded syllables of words on the record sheet 16. The indication for punching of these optional hyphen codes is given to the punch operator in the guide sheet of the illustrative form paragraph by hyphens, although it is clear that any other symbol may be used. In separating the syllables of the words of the form matter, the words which would in all cases be wholly typed on the first line are not separated into syllables by the optional hyphen codes. The other multisyllable words, as desired and selected by the person preparing the punch guide sheet, are separated into syllables by optional hyphen codes. Should the optional hyphen code be sensed while the carriage is in an intermediate position; i. e., before it reaches the right hand marginal zone, then the sensing of and control by the optional hyphen code will be ignored. However, when the carriage is in the right hand marginal zone, the sensing of the optional hyphen code causes the typewriter to print the hyphen and then automatically effect a carriage return operation. For example, in line 5 of paragraph (1) the carriage has reached the right hand marginal zone after the typing of the letter 6 in the syllable so at the end of the line. The next code sensed is an optional hyphen code. Previous to the sensing of this code and as the carriage reached the right hand marginal zone, relay coil 40 had been energized by the previously traced margin zone circuit. Now, when the optional hyphen code is sensed, the following circuit is established:

Optional hyphen printing circuit.From the left side, through contacts 28 and common brush 24, common contact roller 23, brush 24-OH (sensing the optional hyphen code) optional hyphen line 44, relay points 400 (now closed by energized coil 46) line 45, and through the optional hyphen solenoid I5, to the right side.

Energization of the optional hyphen solenoid i5 depresses the hyphen key M to cause the typing of a. hyphen after the syllable ac at the end of line 5 of paragraph (1).

Simultaneously with the above circuit, a b ch circuit is formed from line 45, through nor rally closed relay contacts 332;, and through coil it to the right side of the line. Energization of coil it opens points 26a to cause interruption in. iced of record sheet E0, in the manner previously dcscribed. Simultaneously, a third circuit is formed through the delay coil 36 which proceeds from the normally closed contacts 331) through delay coil 38, to the right side of the line. Energization of coil 36, after a slight lag, closes points 36a to effect operation of delay relay 3! in the previously described manner. At the same time the closure of points 36a now also forms the following circult:

Hyphen C. R. circuit-From the left side.

through contacts 36a, normally closed relay points 33c, line 48, relay contacts d (now closed due to energization of coil 40), line 32, and through the carriage return solenoid 5, to the right side.

Due to the slight lag in closing of points 36a, the above circuit does not form until after the hyphen printing circuit, so as to insure printing of the hyphen before the carriage return starts. For some typewriters, the simultaneous depression of a character key and the carriage return key forces the carriage return to be delayed until after printing and then to proceed. For such typewriters, relay 36 may be designed to close points 36a without delay.

As a result of energization of carriage return solenoid 15, the carriage return operation, as well as the incidental line spacing, takes place following the typing of the hyphen after se" at the end of line 5 of paragraph (1). The remainder of the word selection is printed on the next line after the carriage returns. At the end of the carriage return operation, contacts 31a of the delay relay 31 close'and restart the feed of the tape l0.

For paragraph (2), the margin stop l3 has been set further to the right so it does not reach strip l6 while the optional hyphen codes for the word selection in line 3 of paragraph (2) are passing the line of sensing brushes. Accordingly, the carriage is not then at the right hand margin zone and coil 40 is not energized when the optional hyphensbetween the syllables of the word selection are sensed. Since the coil 40 is not energized, contacts 400 are not made and, therefore, the optional hyphen line 44 is broken at 40c and none of the circuits which were previously described as formed through the optional hyphen code or controlled thereby can now be made. Thus, with the carriage in an inter- N1 Mu mediate postion and while out of the right hand margin zone, the presence of the optional hyphen code on the record sheet W is completely ignored,

hand margin zone is reached as the carriageescapes after typing of the letter 0 in the word price in line 1 of the latter paragraph. Thus, after the word price has been typed, a space code will be sensed, causing" a carriage return operation in the previously described manner. The same thing will occur after the typing of the word which at the end of line 2 and after the word selection in line 3. After the typing of the portion satisfacto (of the word satis factorily) at the end of line 4, the carriage is in the right hand margin zone. The next code sensed is an optional hyphen code which, in the same manner as described before, causes the typing of the optional hyphen. and the carriage to return to the beginning of the next line. In

paragraphv (1), the word satisfactorily automatically is divided as satisfactori-ly, the former portion occurring at the end of line 7 and the latter portion at the beginning or line 8.

During the typing of example (1), the normal hyphen, designated by in the punchguide sheet, and hyphenating the word pro-war is sensed-while the carriage is in the right hand margin zone, and therefore relay coil 40 has been energized. Accordingly, the following circuits are established:

Normal hyphen printing circuit -From the left side, through contacts 28 and 251), common brush 24, contact roller 23, normal hyphen sensing brush 24-NH, the normal hyphen line 41, through the normal hyphen solenoid l5, and to the right side. i

As a result of the energization of the normal hyphen solenoid IS, the hyphen key I4 is depressed causing the printing in paragraph (1) of the hyphen at the end of line 8 following the prefix pre. Due to the carriage being in the right hand margin zone, coil 40 has been energized and relay contacts 40c have been made. Consequently, a circuit is formed which begins as in the preceding circuit and branches ofi from the normal hyphen line 41 through the closed contacts 406, through line 45, contacts 331), through relay coil 26, and to the right side. At

the same time, a branch circuit is formed from contacts 33?) through the delay coil 36 to the right side of the line. As before, due to energization of coil 26, contacts 26a open and break the holding circuit of relay 25 which in turn breaks the circuit of the clutch magnet 22 to interrupt feed of the record sheet. The circuit through delay coil 36 causes the relay points 3621 to make after a slight lag sufficient to permit the printing of a hyphen before the carriage return starts. The closure of points 3611 forms the hyphen C. R. circuit, previously traced in connection with the optional hyphen controls. Consequently, a carriage return operation is effected following the printing of a normal hyphen after the prefix pre at the end of line 8 of paragraph (1). The making of points 36a also causes energization of coil 31 which closes points 310. after the carriage return interval so as to restart feed of the tape. The machine now types the part War of the hyphenated word prewar." After the typing of the period at the end of line 9, a normal carriage return code is sensed causing the normal carriage return operation.

'plained before.

During the typing of paragraph (2), the normal hyphen in pre-war is sensed with the carriage external to the right hand margin zone. Consequently, relay 4B is not energized, contacts llle are still open, and the normal hyphen code does not cause a carriage return operation.

The operation of the machine in transcribing the. coded paragraph designated on sheet l0 into the form indicated by paragraphs (1) and (2) has been explained. A comparison of these paragraph examples shows that example (1) occupies nine lines and has Wide margins, while example (2) occupies five lines and has narrow margins."

This variation in length and margin of the transscriptions has occurred undercontrol of the optional carriage return codes.

The application of th optional carriage return controls to the maintenance of an even right hand margin for form matter, in which variable matter, not derived from the designations, as, for example, manual insertions, is in terposed will now be explained. The manual insertions may differ considerably in length and yet under control of the optional carriagereturn codes, the right hand margin of the same form matter but with different lengths of insertions will be substantially the same. To explain the utility of the optional carriage return codes in connection with manual or other insertions between form matter, the following two examples, numbered (3) and (4) are given. It

is to be understood that the designations (3) and (4) and the colons indicating the beginning of the right hand margin zone are not actually typed. The examples follow:

(4) We are sending your order on to our branch in Kingston, Ontario, Canada, which is our distribution point serving your territory. Because it is closer, filling your order there will reduce both the time and cost of shipment.

The underlining in above examples denotes the manually inserted matter, and it is to be understood that the underlining is not actually typed.

The marginal stops having been set, the transcribing operation proceeds in the manner ex- In both of the above examples, the optional hyphen code causes the word order to be hyphenated, with or at the end of line i. For both examples, the typing proceedsnormally until after the space code has caused an intraline spacing after in of line 2. The next code sensed is a'manual insert'code-the sensing of which by brush 24-MI forms the following circuit:

Manual insert stop circuit-From the left side,

. through contacts 28 and 25b, common brush 24,

paragraphs (3) and (4), it will be seen that due to the variations in length of the different manual insertions, the carriage reaches the right hand marginal zone for these paragraphs while typing different words or portions of the form matter. Thus, for paragraph (3), the right hand zone is reached during the typing of the word point, line 3, Because, hne 4, order, line 5, and time, line 6. After the typing of these words, a space code causes carriage return operations, as previously explained. For paragraph (4), the same right hand margin zone is reached hile typing syllable dis, line 3, syllable ter, his, a, syllable fill, line 5, the word reduce, line 6, and after the typing of the syllable ship, line '3". Under control of the optional hyphen codes, sensed following the typing of these syllables, and under control of the space code following re-- duce, line 6, the carriage return operations are eiiected in the manner described before.

It may be seen from the comparison 0" graphs (3) and (a) that in spite of consi difference in length of the manual inser the same right hand, substantially regul even margin is preserved for both para i without requiring the setting of the stops to be changed in the slightest.

The preservation of the right hand mar n for the form paragraph with manuai insertion or interposed matter is particularly important when this paragraph is to be used in conjunction with other paragraphs required to have the same margins.

The machine, as described above, includes means for interrupting the feed of the record sheet during carriage return operations, whether controlled by the normal carriage return codes or by'the supplementary or optional carriage return control codes. t is understood, however, that it is not essential'to provide means for stopping feed of the record sheet during carriage return operation, as it is well known to provide suific'ient time for the carriage to return by adequately spacing the code which initiates the carriage return from the next code on the record sheet. In that case, the sheet would continue to feed interruptedly after a code thereof had caused the carriage return operation, and the next code on the sheet would not reach the sensing line until after a maximum carriage return interval. With provision for delay by adequately sprgzing the control codes, the stop relay and its circuit, the delay relay 31, and coil 38 controlled thereby would be unnecessary and could be omitted. Further, the delay relay 36 would merely be designed to provide a slight delay in the making of points 35a, which would not have to have a delayed break in order to maintain a circuit through coil 31, but could break immediately upon the passing of the control code which had resulted in the energization of the delay relay 36. plained, the delay in the making of points 36a is not essential when the typewriter has properly designed interlocks delaying carriage return operation until after printing ofa character or symbol, even though the carriage return and character or symbol keys be simultaneously depressed.

It is further understood that the printing of the optional hyphen and control of the carriage return by the optional hyphen code maybe suppressed, if desired, by disconnecting the brush 24-OH from the line 44. Also, control of carriage return by the normal hyphen code may be Moreover, as previously ex-- suppressed by disconnecting line 41 from the wire leading to relay contacts 40e. Likewise, control by the space code of carriage return may be suppressed by directly connecting line 35, without interposition of contacts 40a or 401), to the line 4!. Thus, any one or more or all of the optional controls for the carriage return operation may be selectively utilized.

While there has been shown and described and pointed out the fundamental novel features of the invention as applied to a single modification, will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention. It is the intention therefore to be limited only as indicated by the scope of the following claims. I

What is claimed is:

i. In a machine including apparatus to write indicia along successive lines of a sheet, means controlled by a codal indication for hyphenating the indicia, means for determining an end margin zone of the writing, the first-named means being ineffective to hyphenate indicia written by said apparatus outside the end margin zone, and means controlled by the zone determining means for rendering the first-named means eifective in the end margin zone.

2. In a machine including typing elements to type along a line of a sheet and a carriage for the sheet having intra line movement; means to translate codal indications of matter including means to cause the typing elements to type the matter corresponding to the indications, control means for selectively determining eifectivity oi the translating means only in the translation of a particular codal indication and in causing the typing of the corresponding matter, and means controlled by the carriage in accordance with its intra line position for governing operation of said control means.

3.
