L'UIGI FORTONI, OF LONDON, ENGLAND.

MUSIC TYPEWRITER.

Application filed October 19, 1921. Serial No. 508,851.

To all whom it may concern:

Be it known that I, LUIGI FORTONI, a subject of the King of Italy, residing at Lon don which the following is a specification.

This invention relates to the music typewriting machine for which I obtained United States Letters Patent No. 1,073,976, and it has for its objects to simplify consid erably such machine and appreciably to cheapen its construction.

With these objects in view, I dispense with the numerous piano-like key-levers, together with the stepped divider, of the former ma-" chine, for raising the paper-carriage, and now replace the said key-levers by a handoperated lever, and the stepped divider by a notched sector arranged at the, front of the machine.

And, in order that the invention may be readily understood, I will now describe it fully with reference to the accompanying drawings, wherein:

Fig. 1 is a front sectional elevation of the machine, taken on the line as, m, of Fig. 2, and embodying my improvements.

Fig. 2 vis a plan, the type-keys being omitted, and 4 Fig. 3 is a side elevation with the side of the machine removed in order that the mechanism may be clearly seen.

In carrying out the invention, I retain the transverse shaft 0 and the pinions a mounted thereon at opposite ends, and employed to actuate the racks a operating the paper-carriage b; all these parts being substantially as shown in the drawings annexed to the specification of my aforesaid prior patent.

According to the present invention, I now mount, about midway, upon the said shaft 0,

a bevil wheel at adapted to gear with a bevil wheel at, mounted in a bearing d fixed to the base of the machine, and the operation of which wheels, by the means hereinafter described, causes the pinions a to actuate the toothed bars or rodsa and so raise, or lower,

' the paper-carriage b.

The means for operating the paper-carriage consist in a flexible or springy' handlever e mounted fast on the axle of the bevilwheel d, and extending outwards to within easy reach of the typists hand. This lever is provided, at its outer, end, with a knob or head e whereby it can be readily operated England, have invented new and use-' ful Improvements in, Music Typewriters. of

tor f, and marked thereon in any convenient manner, is the representation of a piano key? board g, having, say, 32 keys corresponding with four octaves and three degrees or notes.

Each of said notches corresponds with one key, so that the movement of the hand-lever 6 between each of these notches operates the bevil gears d, (Z which, in their turn, by acting on the pinions an effect the movements of the paper-carriage b; the distance between the notches being such as to correspond with, say, 1 m/m with the stave on the music sheet; and these 32 notches will impart a rise of 32' m/m for one complete stroke of the lever -e, that is to say, from one end of the sector to the other end thereof. By releasing the lever, and moving it to the extreme right of the machine, the paper-carriage will be lowered" to the bottom of its movement.

At the centre of the notched sector f there is provided, at 9 the representation of the music note 82' (b) on the third line of the stave in the treble clef, for the purpose of indicating to the typist that, by moving the lever e to the ri ht, a higher octave will be obtained, while y moving it to the left a lower octave will be obtained. A further purpose of this music note 82' is to indicate to the typist the pitch of the printing line of the machine, and at which point the musicsheet must be fixed before starting to type. This may be accomplished by providing the paper-carriage with pointers, on each side, to indicate the printing line for use for adjustin the paper on the carriage to the note g The notched sector is removable, so that when it is required to type music on a sheet having a stave of a different width, another sector can be applied in which the distance between the notches is such as to correspond with the stave width required.

By means of the abovedescribed im operating provements great accuracy is obtained in bringing the notes to be printed at the proper pitch on the stave, or above it, or be- Having now described my invention what I claim 1s:-

' 1. In a music type-writer, the means for the paper-carriage to bring it to the requlred pitch to receive the impression of the notes, signs, and characters, comprising a pair of bevil gears one of which is operated by a hand-lever and imparts motion vto the other which transmits it to the pinions gearing with the movable racks carrying the paper-carriage, the said lever being provided with a tooth adapted to engage a detachable and notched sector arranged at the front of i the machine and bearing the representation of a pianoeyboard and with a pointer working over said sector and indicating the note to be printed, the notches in the sector Y corresponding with the number of 1pianokeys marked thereon, and each 0 said notches corresponding with the pitch or.

spacing of the stave on the music-sheet, sub stantially as herein described;

In a mus1ctype-writer, as above LUIGI FORTONI. Witnesses:
