T0 on whom it may concern:

Be it known that 1, Ln: CHAMBONNAUD, a citizen of the Republic of France, residing at Limo es, France, have invented certain new an useful Improvements in Stenoaphic Machines, of which-thefollowing is a 11, clear, and exact specification. This invention relates to certain new and useful improvements in stenographic maro chines; and it has for its objects, among others, to. construct a machine ermitting of plain and clear stenographytfiat is to say, of Writing speech not by means of special signs'requiring for their typing or printing, I 5 as well as for their reading, a special initiation, but sim 1y by inscribing the honetic sounds or syl ables of the words wit out respect to the ortho aphy. In order 'to accomplish this rapi lythat is to say, to be able to type or print instantaneously all the elements composing a word or a syllablean arrangement should be used possessing several printingoints which Wlll be put into action by stri ing at the same time several keys, whence it is necessary to adapt to the machine a specialkeyboard determined by the maximum number of printin -points employed and by the language in W ich it is desired to stenograph. According to this principle the following English sentence, Short writing is indispensable to business peoIple,,'

for instance, could be reproduced as fol ows: Shor t ri ting iz in dis pen so bl tu biz nes pee Ip1.

5 T e accompanying drawings represent several forms of carrying into effect such a machine and its acce ssorles, in which Figure 1 is a view of the type of keyboard.

Figs. 2, 3, and 4 are diagrammatic views of three types of keyboards, and Fig. 5 is a diaaromatic plan viewiof a of machine. *igs. 6 to 10 are detail views." Fig. 11 is a diagrammatic side View of the interior parts of a t e of machine, and Figs. 12 and 13 .45 show different methods of putting into prac tice the controlling-levers of. the typing or printing hammers. I Fig. 14 shows in perspective the arrangement of the inking and typing or printing ribbons. 15 1s a diagrammatic plan view of a mod' catlon of the machine, and Figs. 16 and 17 show an arra'n' ement of keyboard for only one hand.- r is stenographic machine consists, essentially, of a, complete ke board, two to four ammers, each group saving-its own printing-point, a. printingribbon, an inking device, and levers connected to keys and transmitting the movement to the type-carrying hammers.

Before describing the details of construction of the said machine it will be convenient to specify the construction of the different keyboards which can be used.

Su posing the honetic elements are divide into two c asses and designated as cf (the phonetic consonants) and v, (the phonetic vowels or di hthon s,) the syllales will be, for exampe, of the form c,

c, v, ct hat is to say, for elements; To print these four elements at once, amachine must be used with a keyboard controlling four rintingpoints at once. This theoretic keyfioard is represented in Fig. 1, and according to the number of phonetic elements to be composed a complete-keyboard will be adapted withfour, three, or two sep arate subsidiary keyboards.

In Fig. 1, 1, 2, 3, and 4 re resent the keys.

For the printing of the nglish language, for instance, a complete keyboard can be used, as shown in Fig. 2, composed of four separate subsidiary keyboards 5, 6, 7, and 8, the whole of the keys of which will permit of the printing of all the consonants or joint consonants, as well as the vowels and diphthongs b, d, f, g, t, v, a, e, i, o, u, ei, ou, oi, ing. In the drawing each key carries its own indication, which 1t will-cause to be printed, andthe whole keyboard, Fig. 2, having about fifty-five keys, can be arranged, if desirable, similar to the keyboard of a piano. It will be composed, first, of the keyboard 5 of joint consonants on the left, containing twenty-two keys; secondly, of the keyboard 6 of the modifiers with four keys; thirdly, the vowel-keyboard 7, with eleven keys, and, finally, the keyboard -8 of modifiers of the second series, with eighteen keys. By theterm modifier I mean either a consonant or a vowel following and modifying the sound of the first vowel or consonant pronounced. It being understood that in a syllable with four elements 0, c, v, c the first consonant constitutes the one principally pronounced, the second only playing the part of the modifier of this pronunciation, the vowel .being also a principal element and the con- -sonantfollow1ng only serving to modify the sound of this vowel. It would alsobe possible by using an arrangement already adopted in certain ty e-writing machines to adopt a keyboard suc as represented in Fig. 3, containing twenty-eight keys 9, each of which represents two elements, and four change-keys 10. The latter permit of presenting to the printing-point either one of the two phonetic elements which represent the ordinary keys. Proceeding on the same principle, a keyboard can be adopted as shown in Fig. 4, which onlyeft, and theother four will constitute the keyboardofthe vowels and. the -most .fre-

' qnent vowel-modifiers. "The change-keys will be operated bythe two thumbs and can also .be .provided with. arresting-stops, as .in certain other writing-machines, in order to present on=theprinting-point for a certain time, according to, desire, the second or third phonetic elementof the ordinary keys.

*tFig. 5 represents a diagrammatic plan view dfa stenographic machine provided with. a keyboard such as is shown in Fig. 3. On a framework 13 are supported at suitable points printing-levers 14 of difl'erent types,

some of which areseen in Figs. 11, 12, and 13, .saidlevers carrying at their extremities ordinary keys 9. The printing-levers 14 are connected by convenient supports to the levers .15, carrying characters, the latter acting on .theiinking device, which may be a ribbon 16 (see Fig; 14.}similar to those used in ordinary type-writing machines, actuated bya movement from left toright and wound for this purpose on spools. 17 18. (See Fig- 14.) This ribbonpasses at 19 before the printing- ;ribbon 20, (see- Fig. 14,).- a ribbon of paper identical with these used on the Morse telegraphic instruments, moving-from right to left, ,which is unwound and wound cnthe spools 2 1'. The spools are controlled either by a clockwork-movement provided for this purpose or by a spindle-23 and gearwheels 24,;utilizing the depression ofrthe keys of-the principal key- .board,.or any other. known manner as al-,

ready used in .certain typewvriting machines. The inking-ribbon anduts manner. of. actuationis that common-in the Remington typewriter.

As. already explained, .thk63b0fi1'd5 rep- ;resented in Figs. 2. and: Bhavefour printingpoints, .forinstance, f1" 0 kasseeltm Fig.6, so that when the keys correspondingtof, fr/Y a, fki. are strucksimultaneouslythe hammers ca :theccrrespcnding characters are suitablyp aced and.print:thephonetic syllables frak" of .the .wordfractional, for example. In the simple keybcard, such as these represented E1g2r2; thereis only onephonetic elementfcreachake ran-mnsoquence each hammer carries on y one character. Fi 8 shows a front view and section of one. of t iese hammers 25. ,The keyboard shown in Fig. 3 and adapted to the machine according to Fig. 5 is provided with hammers 25, each of which carries two characters, as shown in Fig. 9.

Fig. 15 shows in perspective a stenographic machine provided with a keyboard as shown in Fig. 4, the details ofwhich have been described above. This form has two printingvpoints according to Fig. 7 and is provided with hammers carrying three letters or charac- Yters, as shown inFig. 10. -The same stencgraphic machine could be used for the English, French, German, Italian, or otherlanguages by adapting thereto a suitable keyboard and with a sufficient number of keys, according to the phonetic elements to belrepresented. Keyboards such as those .f described above can also be adopted. For the designation of figures conventional :letters could be adopted, chosen, preferab.ly,.in the same group of keys and placed between .two dashes, for instance, in order to facilitate; dis tinction. The system of leversdesignedwto transmit the movement of. the shift-key 1'0, Figs. 3 and 5, will also beseen-by dotted lines in Fig. 11 and full lines in Figs; 12 and: '13, such vmovement being, transmitted to the plate which supports thehammer carrying the exactly at the height of the-.printingmoint,

Fig. 6. This arrangement is, moreover,,s1m1- lar to that used for the samepur ose'in typewriting machines-with several 0 aracters on the one key. In each machine the keybcard is simultaneousl operated-With thefingers of the right an left hand. Fen- .thearke board shown in.

At :the same time the hammers area-displaced,

as explained above, and the rintin is. conveniently brought about. en t 'e shift key is then released, the parts return to their normal position under the simple action of gravity.

In certain cases a simplified keyboard for only one hand could be used, as shown in Figs. 16 and 17, comprising two series of keys i,- vided into four groups, each having its own printing-point. This form is operated by the combination in printing of signs of one or the;

other series in order to obtain new characters. For instance, with n and v, m will be obtained by putting'b'oth together, with c and j printed and 'oined to ether g.-

will be obtained, .0 an i give a, and so on. p y

The different parts above described can be used. in certain cases in combination with' other or ans of existing type-writin machines, w liich will be thus transforme into stenographic machines.

Having thus described my invention, what I claim as new 1s- 1. A stenographic machine, havin a com-- plete keyboard comprising four su sidiary and separated keyboards, one of joint consonants, one of modifiers, one of vowels, and one of modifiers of said modifiers,'a lurality oi groupsof type-carrying hammers, evers to actuate and to advance the said hammers toward the printing-point to strike the inking and printing ribbon, said keyboard having four printing-points, so that when certain nants, one of modifiers, one of vowels, and

one of modifiers of said modifiers, a plurality of groups of type-carrying hammers, levers to actuate and to-advance the said hammers toward the printing-point to strike the inking and printing ribbon, said keyboards having four printing-points, so that when certain keys are struck, the hammers carrying the corres onding characters are simultaneously place and simultaneously print the proper honetic syllables, a shift'key and a system of evers for transmitting movement thereto.

In witness whereof I have hereunto set my hand in presence of two witnesses.
