MECHANICAL MUSIC-CHART.

SPECIFICATION forming part of Letters Patent No. 658,902, dated October 2, 1900.

l Application filed May 2, 1898. Serial No. 679.483. (No model.)

To all 71171/0711/ it nifty concern:

Be it known that I, SAMUEL B. TURNER, a vcitizen of the United States, residing at Chicago, in the county of Cook and State of' Illinois, have invented certain new and useful Improvements in Chorigraphs, of which the following is a specification.

This invention relates to improvements inv a chorigraph or mechanical mnsicchart; and it consists in certain peculiarities of the construction, novel arrangement, and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

The principal objects of my invention are, first., to provide a chorigraph or mechanical music-chart with selfadjusting marks of transposition and an automatic transposer for students and teachers of vocal and instrumental music which shall be simple in construction and operation and being especially arranged and designed for the piano, organ, and similar instruments; second, to provide such a chorigraph or chart which will illustrate the diatonic scales in all the keys, and, third, will show the relation between major and minor music, with the principal chords of each, as commonly employed in piano and organ accompaniments. Other objects and advantages of my invention will appear in the description hereinafter contained.

In order to enable others skilled in the art to which my invention pertains to make and use the same, I will now proceed to describe it, referring to the accompanying drawings, in Which- Figures l and 2 are views in front elevation of' the chorigraph or chart, showing it ready for use in the key of F major or its relative D minor. Fig. 3 is a detached front view in elevation of a portion of the automatic transposer or sliding piece, showing the marks of transposition, or, as is more commonly known, the signatures thereon. Fig. e is a cross-sectional View taken on line 4 4 of Fig. l, showing the detailedconstruction of the device. Fig. 5 is an enlarged View in elevation of a portion of the device, showing it ready for use in the key of Ft; major or DH minor; and Fig. 6 is an enlarged fragmental View in elevation of the device, showing the characters on the black spaces thereof.

.music Similar letters of reference refer to like parts throughout the dierent views of the drawings.

H represents the body of the chart, which may be made of any suitable material, but preferably of' cardboard or other thin material, and is usually rectangular in outlines, as shown in the drawings. This body or supporting-piece H is generally formed of three pieces 7i 7?/ 7b2, glued or otherwise secured together in such a manner as to form a cavity h3 for the operation of the transposer or sliding piece I, which is made of cardboard or other thin material and is provided with a series of marks of transposition or signatures J JQ located at or near the left-hand end of the transposer. These signatures or marks of transposition J J may be separated by characters of' explanation J2, arranged longitudinally on the transposer and between the signatures, as shown in Fig. 3 of the drawings, or may be omitted, as usual, in written Arranged in an inclined longitudinal line on the transposer or sliding piece I are a number of black spaces K, with Arabic figures l to 7,inclusive, (the figure l being repeated,) representing the diatonic scale. Below these black or colored spaces and arranged in horizontal lines are Arabic figures and words representing the diatonic scale, either or both of which may sometimes be omitted. The transposer or sliding piece I is formed at each ot' its ends with inclined edges t' to slide on and contact with the inclined portions 71,4 of the body 0r supporting piece or back, so that when the transposer is slid back and forth by means of cords hi or otherwise it will rise and fall for the purpose presently to be explained. The transposer is also provided with shoulders t" on its upper and lower edges to engage shoulders or recesses 7L in the body or supporting-piece to prevent the transposer being displaced or drawn too far in either direction. The piece h2 or the front portion of the body is provided with a number .of note-shaped openings Z, representing the chromatic scale, which openings are arranged diagonally to correspond with and to represent alternately the tones produced by the white and black keys of the instrument and are employed to disclose the Arabic figures on the black spaces of the IOO transposer and a portion of said black spaces to give the dia-tonic scale. The piece h2, or front portion of the body is also provided with an opening L to disclose the signatures or marks of transposition J J on the transposer. The piece h2 or front portion of the body is further provided with staffs L' and bars L2 and clefs, which are located above the horizontal opening L3 in the lower portion of the piece h2 or front of the body which is employed to disclose the characters and words on the transposer representing the diatonic scale. Below the opening L3 the piece h2 is provided with a number of black spaces L7, representing the keys of the instrument producing the Hats and Sharps between the whole tones in the key of C major. On the said spaces are characters used for the same purpose. Below the opening L3 the piece h2 or front of the body is formed into blocks L4, representing the white keys of the instrument, producing the tones of the diatonic scale in the key of C major, and said blocks are provided with letters L5, corresponding with similar letters L6 on the staff above, the former series of letters representing the manner in which the music should be vplayed if written in the key of C major and the latter corresponding with the music as written if in the key of C major.

Between the clefs and on the front of the body are displayed the Words Key of major7 and Relative of minor in horizontal lines in such a manner that the letters which the signature represents will be exposed through the opening L, the said signature being exposed at the same time.

Secured to the body, so as to be in front of the front portion thereof, is a transparent piece M, which is provided with vert ical lines m, which extend across the opening L3 and register with the bars L2 on the front of the body, thus making the same continuous from the staff to the black spaces L7, representing the keys of the instrument, as before ex plained, some of them extending to the lower portion of the body. The transparent piece M is also provided with horizontal lines m and m2, the former extending across the opening L and the latter across the noteshaped openings but either or both of said series of lines may be sometimes omitted; but I prefer to use them, for the reason that they will make the lines composing the staffs continuous.

Instead of placing the lines m on the transparent piece M, I may omit them therefrom and place them on the transposer; butIprefer to use them on the transparent piece, for the reason that if placed on the transposer they would appear broken unless accurately registering with the lines above and below the opening.

The Arabic figures displayed on the black or colored spaces K on the transposer may sometimes be omitted; but it is preferable to use them.

Vhile I have shown the chart or device arranged for a five-octave instrument, yet I do not desire to limit myselt` to such arrangement, as I may construct and arrange it for a larger or smaller number of octaves without departing from the spirit of my invention.

The lower portion of the device is provided with a piece of felt N or other soft material for the keys of the instrument to strike against to prevent rattling and to protect the keys.

In using my chorigraph or chart I place it in a vertical position, with the black spaces L7 directly over the corresponding keys of the instrument, in which position the blocks L4 will lie directly over the white keys. W'hen it is desired to play in the key of F major or its relative D minor, the transposer is slid toward the left or bass in the cavity of the body by means of one of the cords h5 or otherwise until the signature of F major or its relative D minor shall be exposed through the opening L in the front of the body, as shown in Fig. l of the drawings, in which position it forms the diatouic scale in the key of F major, a portion of the black spaces K and white iigures thereon showing through the proper note-shaped openings Z in the front of the body, and the Arabic iigures and words representing the diatonic scale will at the same time be located so that the said ligures will correspond with the diatonic scale in the key of F major and the words to correspond with the notes commonly used in the same key in vocal music. When the parts are in the positions above mentioned, the vertical lines m on the transparent piece M will register with the lines L2, forming the bars, and the lines m' thereon will register with those forming the staffs extending across the opening L, while the lines m2 on the piece M will extend across the note-shaped openings, thus always affording continuous lines, whereas if the said lines were omitted from the transparent piece and placed on the trans poser they might appearbroken or irregular.

Vhen it is desired to playin the key Of Fg major or its relative Dit minor, the transposer is slid toward the right or treble, so that the signature of Ft# major or its relative Dit minor is displayed through the opening L, as shown in Fig. 5 of the drawings, in which movement of the transposer it will be caused to rise slightly within the cavity of the body by reason of its inclined edges riding on the inclined edges of the body, thus forming the diatonic scale in the key of Fit major by exposing a part of the black spaces K and the figures thereon through the proper note-shaped openings and also transposing what was previously shown in the key of F major to the key of F5; major.

From the foregoing it is evident that the ten remaining keys, with their relative minor keys, may be affected and transposed in a like manner.

I-Iaving thus fully described my invention,
