ROBERT MCKEAN JONES, OF STONY POINT, NEW YORK, ASSIGNOB TO REMINGTON TYPEWRITER COMPANY, OF ILION, NEW YORK, A CORPORATION OF NEW YORK TYPEWBITING MACHINE.

Application filed Kay 18,

My present invention relates to improvements in keyboards for the katakana characters of the Japanese language, and the main object of the invention is to provide a new and improved keyboard arrangement for the Japanese katakana characters.

Until quite recently the katakana characters were written only in perpendicular columns, the columns running or being arranged from right to left. The new system of writing the characters adopted by the Japanese, however, makes use of an arrangement "where by .the characters are horizontally disposed and extend from left to right as is common to the English and other occidental languages. The new system has also simplified the form of the characters so as better to adapt them for printing and typewriting purposes while still retaining resemblance to the original form for easier identification. The new system also uses ordinary Arabic numerals instead of the clumsy Chinese system heretofore employed and at the same time it favors the use of punctuation signs and other signs common to occidental languages and many of which have now been introduced into oriental writing systems.

One of the purposes contemplated by the present improved arrangement is to facilitate learning and use of the new katakana system in typewriting machines by making a convenient and logical arrangement of the characters in my new and improved keyboard.

Theorigmal language of the Japanese is phonetic and is chiefly expressed in characters equivalent to a combination of an initial consonant and a final vowel of the Roman alphabet.

Each syllabic combination is represented by a different form, as, for instance: ka, ku, ki, k0 and he foreach one of which there is-a different katakana form. This syllabary numbers about forty-eight forms which for the sake of greater distinctiveness are termed main characters in the present discussion. Additional characters are chiefly duplicates of some of the main characters in a smaller size and used in connection with other main characters to indicate certain modifications of the sound of the main characters. There are also two accents to indicate a. harder or softer ronunciat on of the characters to 1927. Serial No. 192,656.

which they are added, thus practically adding additional syllables.

For example, the character for the sound k0 identified in both of the illustrated keyboards by the numeral 54 when marked with design that may conveniently be employed for types in writing machines.

For convenience of reference the transliterated characters that go to make up both the eighty-four character and ninety-two character keyboards are set forth below, associated with a series of numbers running from 1 to 84 inclusive. Owing to the difliculties encountered in printing, no attempt will be made to illustrate the actual ka-takana- I 18 indicates yo.

Referring first in detail to the eighty-four character keyboard illustrated in the original Japanese katakana-in Fig. 1 and which is transliterated in Fig. 2, it will be seen that the key-caps for the four banks are represented diagrammatically each by a double square, this being the ordinary conventional or diagrammatic means of representing the characters in a single shift keyboard. For convenience of reference, each instance which represents the lower-case h'aracter, is designated by the numeral 85, the upper square, representing the correthe lower square in spon mg upper-case character, being indicated by the numeral 85. v eighty-four character keyboard in detail, it comprises a top bank which case, printing .chine is depressed, a set of the so-called Arabic'nume'rals, one to nine inclusive and zero. Only the a numeral, in this instance 1, as appears from he drawing and from the above list. lower-case of the top bank, which prints when the shift key is in normal illustrated correspond to 1 ni, no, nu, ne. These characters, as appears from 'Fig. 2, bear respectively the identifying numerals 40, and 57. Comparing these characters with the corresponding numbers in the lower-case squares 85 of the .top row in Fig. 1, it will' "be seen that they trarisliterated characters in Fig. 2 to be compared with the haracters inFi Taking up the 10 has in the upper when the shift key of the ma- 1 key is specifically indicated by 11 In the position, the forms re, ru, r0, ri, ra, na,

correspond, enabling the original Japanese katakana Similarly a comparison of the upper-case aracters in the second bank from the top of designated by the numerals 7, 42, 63,64, 66,

- 67, 68, 65, 62, 52 and 9, these being' resp ectively small yu, se, the bracket sign, the opposite bracket sign, the diagonal-sign, the underscore sign, the percent mark, the yen sign, the Japanese sign for the double hyphen, W0 and small wa. The lower-case characters in the second row from the top of the'eighty-four character keyboard, Figrl, are numbered respectively 17, 25, 43, 33, 5'1, 26, 36, 35, 54, 45 and 19, these corresponding respectively to the transliterated characters yu, su, so, shi, sa, ka, ku, ki, k0, kc and wa. Similarly the up per-case characters in the third row from the top, represented by the numerals 6, 69, 41,- 70, 71, 72, 73, 61, 74, 47 and 59, correspond respectively with the transliterated characters small ya, the straight apostrophe sign, small tsu, the quotation mark, the colon, the period, the comma, the dash or prolongation sign, the interrogation mark, me and the handakuon accent. The lower-case characters in this row, identified by the numerals 16, 23. 50, 32, 31, 22, 37, 55,56, 46 and 60, correspond respectively with the transliterated characters ya. te, tsu, to, chi, ta, ma, mi, mo, inn and the dakuon accent. The upper-case characters in the bottom row of the eighty-four character keyboard. identified by the numerals 8,

75, 44, 11, 76, 2, 21, 3, 5 and 4, correspond respectively to the transliterated characters, small yo, the parenthesis sign, he, fu, the opposite parenthesis sign, small a, small i, small u, small 0, and small ye. The lower-case characters in the bottom row, identified by the numerals 18, 20, 53, 34, 27, 12, 24, 13,15 and 14, correspond respectivelywith the transliterated characters yo, ho, hi, ha, n, a, i, u, o and ye (e).

The convenient arrangement of the initial consonants in the eighty-four character keyboard will be apparent from an inspection of Fig. 2. The consonants s and k occur most frequently in writing, and these are accordingly placed in the second row of the keys at the left and right of the middle position.

Next in order of frequency of use are the consonants t and In, and the characters involving these are accordingly placed at the left and right-hand sides of the middle in the third bank of the keys. These positions provide' for an approximatelv even division of labor between the rightanli left-hands of the operator, and, accordingto my analysis, comprlses nearly one-half of the entire work of writing the Japanese language.

' A further improvement resulting from the present arrangement is calculated greatly to facilitate the-use of the typewriting mac ine in writing Japanese .katakana characters;

namely, the vowel sounds of the ,syHabic characters are also arranged in an orderly fashion up and down or vertically of the keyboard in such a manner, that as a rule, the

same vowel in any of the syllabic characters is found in about the same position in each bank and will come naturally under the control of the same finger of each hand. Thus, the vowel sound of a, being the most frequentl used, is located at or about the middle of eac 1 bank of keys, and the other vowel sounds are distributed towards the right and the left in order of frequency ofuse as'ascertained by me. Generally, the order of fre-' quency of use is a, i, o, u and e, but some slight variation of this order will be observed due to the fact that the combination of' certain vowels with some consonants occur much more frequently than the-same vowels do with other consonants. For example, the kn occurs more frequently than does the k sound with any other vowel excepting a. i This fact justifies the placing of the ku character nearer tothe middle of the keyboard in the line of ks than where the frequency of' its use would rightly place it, that is in or near the fourth place.

On account of the insufficient number of keys in the eighty-four character keyboard, it is necessary to put a few of the least-used characters in the upper-case to be operated when the shift key is depressed. This number, however, is very small, the total relative use of the characters so placed being approximately three per cent of the whole.

In the ninety-two character keyboard, illust-rated in the original in Fig. 3 and in transliterated form in Fig. 4, all of the main characters except the seldom used one for he, are conveniently-located in the lower-case disposed in order of relative frequency of use. Those used most- .often are located near the middle of the keyboard under the strongest and most supple fingers of the operators hands, and thence proceeding to the right and left in the order of relative use, so that the least used characters are located where they will be struck by the least active fingers. Also, as in the eighty-four character keyboard, the vowel sound of the syllabic characters are disposed up and down or vertically in order, so that the same vowel is found in or about the same position in the several banks and will come naturally under the control of the same finger of the operator.

' Referring specifically to the ninety-two character keyboard, Figs. 3 and 4, the uppercasein the top row contains the nine Arabic 39, 30, 28, 29, 38, 48, 57 and 52; and the corre: .sponding transliterated characters are in order, re, ru, ro, ri,ra, na, ni, no, nu, ne and W0. Next to the top bank in the upper-case are the characters identified by the reference numorals 7, 83,78, 63, 64, 66, e7, 68, 65, s4, 82

' parenthesis sign,

and 9. For the most part these are sign characters and are respectively as will be seen from the corresponding transliteration in Fig. 4, small yu, the pound sterling sign, the sign, the bracket sign, the opposite bracket sign, the diagonal sign, the underscore sign, the per cent sign, the yen sign, the tael sign, the dollar mark and small wa. The lowercasec-haracters in the second row from the top, identified by the reference numerals 17, 42, 25, 43, 33, 51, 26, 36, 35, 54, 45 and 19, correspond respectively to the transliterated characters, yu, se, su, so, shi, sa, ka, ku, ki, ko, he ,and wa. In the third bank from the top in the upper-case are found the characters mostly punctuation marks and the like, which are identified by the reference numerals 6, 69, 41, 70, 71, 72, 73, 61, 74, 81, 62 and 59; corresponding respectively to the transliterated characters small ya the apostro he sign, small tsu, the quotation mark, the co on, the period,

the comma, the dash or prolongation sign, the

question mark, the exclamation Japanese hyphen, and the ban-dakuon accent mark. The lower-case characters in this third bank from the top are identified respectively by the reference numerals 16, 23, 50, 32, 31, 22, 37, 55, 56, 46, 47 and 60, corresponding respectively to transliterated characters as follows: ya, te, tsu, to, chi, ta, ma, mi, mo, mu, me, and the dakuon accent mark. In the upper-case the lowest bank of keys contains characters identified by the reference numerals 8,79, 80, 44, 75, 76, 2, 21, 3, 5 and 4, correpoint, .the

' sponding respectively to the transliterated characters small-yo, small fu, small ho, he, the the opposite" parenthesis sign, small a, small i, small u, small 0', and small ye. The "lower-case characters in the bottom bank of keys are identified respective ly by the reference numerals 18,11, 20, 53, 34, 27, 12, 24,- 13, 15 and 14 corresponding respectively to the transliterated characters yo, fu, ho, hi, ha,n, a, i, u, o and ye.

While the two keyboard arrangements above described in detail are of course adapted to various styles of writing machines, I

have illustrated them as applied to the standard Remington typewriting machine parts of which are illustrated in Figs. 5' and '6. The main frame of the Remington machine comprises a base 86, upright posts 87 and top plate 88, at the forward side of which is disposed a frame plate 89. The type bar support or segment 90 ofthe machine has mounted on it a pivot wire 91 which provides a pivot for a set or series of type bars 92 each carrying a type block 93 having two types. The type bars are disposed in an arcuate series below the platen (not shown.),and normally rest at thelr type ends on a support 94, being adapted to be swung upward and rearward into cooperative contact with the platen. The type bars are gulded 1n the1r swinging movements in radially arranged slots 95 cut inthe lower portion of the segment 90. The heel portion of each type bar is provided with a cam slot 96 with which engages an actuating pin 97 projecting laterally from the upstanding arm of a bell crank 98 having a stationary pivot 99 and pivotally connected at 100 with a jection 101 upstanding from a. key lever 102 and integral therewith. The set of key levers is horizontally disposed, each lever being fulcrumed at its rear at 103, and thence extending forward, terminating in a stem 104 WhlCh-lS provided with a key cap or button 105. (It will be understood that these key caps 105 are identified in the diagrammatic views Figs. 1 to 4, by the reference characters 85 and 85.) There are four rows of caps or keys 105 constituting the keyboard, the stems 104 the rows are in banks or steps as is well understood,,the highest bank at the rear. The

being of graduated height so that" or the other of the types at its free end to contact with the platen. Normally the platen is in what is termed lower-case position and the lower-case typesof the print through the usual ribbon When the platen is shifted and maintained in shifted position, an actuation of one of the type bars will cause its upper-case type to print. .The lower-case types are the inner types on the blocks or those nearer to the pivot wire 91, the upper-case types being the outer types.

' For the purpose of promoting understanding of the relationship between Figs. 5, 6 and the diagrammatic views (Figs. 1 and 3) of the type bars will (not shown).

I keyboard, I have shown in Fig. 5' the complete or full keyboard of a standard Remington .typewriting machine having ninety-two characters, this keyboard being represented by the key caps or buttons 105, and in a few instances showing the characters on the tops of the key caps. These characters it will be Jlu understood, correspond throughout with the full set of characters shown In the diagrammatic view, Fig. 3, wherein as stated each double square 85, 85* corresponds with one of the key caps 105. Fig. 5 further illustrates the fullset of type bars of the machine with their type blocks, the keys each being shown as connected with block by a dotted line d. assumed as representing the actual connections or trains of devices between the keys and the type bars, one of such trains being fully shown in Fig. 6. In the style or design of-types illustrated in Figs. 1 and 3, and heretofore described, I have The lines (5 may be diagrammatically ing main characters.

used. The tabulation shows V followed generally the style and design employed for printing types, and althou h I have made changes in various details, no c aim of course is made for such differences as they are merely specific matters of design. As heretofore stated, the Japanese katakana characters shown in Figs. 1 1 are to be preferred to the old style or design of types. It is to be understood, however, that if found desirable for any reasonthe characters of the sort made with the brush pen may be employed within the scope of my invention. In order to make this point clear, I have illustrated in Fig. 7 several of the katakana characters-of the sort I have preferred to employ, these corresponding with those shown in Figs. 4 and 3 and identified by the reference numerals 52, 45, 9, and 19, the corresponding brush pen characters identified by the same reference numerals being illustrated in Fig. 8 immediately to the left of Fig. 7.

One of the obvious advantages of my improved key-board arrangement is that it will greatly promote the memorizing of the positions of the characters in the keyboard, and will facilitate the rapid acquirement of the best method of operating the typewriting machine; that is, the touch system in which the typist does not look at the keyboard when writing. It will be observed that the small characters for modifying sounds 'are in each instance placed in theupper-case position upon p the same type bar that carries the correspond The characters representing certain sounds partaking of the nature of the vowels, yet sometimes used as initial consonants, are grouped along the sides of the keyboard. These are yu, ya, yo on the left-hand side; and on the right-hand side are wo, wa, ye (often used in place of e.) in the lower-case position, each having the corresponding small-sized character on the same type bar but in the upper-case position.

My improved keyboard arrangement is based on the tabulated results of a full and careful examination of the frequency ofuse of more than two thousand characters of the Japanese katakana syllabary. Experience has shown that such a result affords a very fair approximation of the actual average that the syllables beginning wlth k, s, m, and t include about forty-five per cent of the whole. These syllables have all been located in the central portion of the keyboard and are readily accessible to each other, as well as to other syl-- lables which they precede or follow. The

vowel components of the syllables are also.

with similar reference to comparative accessibility and frequency of use. The a sounds which comprise about thirty per cent of occurrenceare in the central portion of the keyboard. The next sound in order of usage is the i sound which comprises about twenty-five per cent andthese characters are placed and dakuon accent.

by Letters Patent, is

used being in nearer the central portion on the right and left-hand sides. Adjacent to these are the 0 sound characters with a usage of twentyper cent followed by the u sound characters with a usage of over fifteen per cent, and the e sound characters with a usage of about nine percent.

Comparing Figs. 1 and 2, that is the eightyfour character keyboard and ninety-two character keyboard, by the aid of the transliterated characters in Figs. 3 and 4, it will be observed that the keyboards are to a large extent identical in the topmost bank. All the characters except the 3 are found in both key-boards arranged in the same order. In the second bank the following characters in the lower-case to ether with their corresponding upper-case c aracters are found in both key-boards, viz, u, so, shi, sa, ka, ku, ki and wa. In the thir bank from the top the following characters are.

found in the lower case, together with'corresponding upper-case, are found in both keyboards, viz, ya, te, tsu, to, chi, ta, ma, mi, mo Inthe lowermost vbank the two keyboards have the following transliterated characters in common, reference being had to the lower-case characters, the upper-case characters likewise corresponding, viz, yo, hi, n, a, i, u, o and ye.

Various changes may be made without dearting from my invention.
