MUSIC SCALE AND CHORD INDICATOR.

Patented Apr. 4,1882.-

BY W

ATTORNJ UNITED STATES PATENT OFFICE.

CHARLES H. HAUSOHEL, OF NEW YORK, N. Y.

MUSIC SCALE AND CHORD INDICATOR.

SPECIFICATION forming part of Letters Patent No. 255,979, dated April 4, 1882.

Application filed September-16,1881.

To all whom tinny concern Be it known that I, GHAnLEsH. HAUSOHEL, of the city, county, and State of New York, haveiuvented certain new and useful Improvements in Scale and Chord Indicators, of which the follou ing is a specification.

The object of this invention is to furnish to amateurs, advanced pupils, leaders ol" quartettes and singing societies, vocalists, and others an improved scale and chord indicator, by which, in addition to the audible sounding of the trichord of any key the same trichord is visibly represented in characters; furthermore, the entire scale, with its sharps and tlats, the signatures of the keys, and their relative minor keys, indicated, and by a simple mechanism the transposition of one key into another in an instant accomplished.

The invention consists essentially of an interior reed-cylinder and an exterior slotted casing, which latter turns on the shaft of the reed-cylinder and is provided with recesses in its heads for rendering visible the chords and their names at one side and the signatures of the keys at the other side of the reedcylinder. The circumference of the casing has transverse slots and openings for the exit of the air from the reeds and indicating the sharps and flats. A slide plate, which is guided in a suitable manner by the exterior casing, admits the sounding of the major or its relative minor chord, according to the relative position of the slide-piece. v

In the accompanying drawings, Figurcl represents a perspective view of my improved scale and chord indicator; Fig. 2, a vertical central section of the same. Figs. 3 and at are detail views of the circumferences of the reedcylinder and of the casing, shown as rolled out for greater clearness. Figs. 5 and 7 are end views, partly in section, showing the indicator from opposite sides; and Figs. 6 and S are end views of the interior reed-cylinder with the easin g removed.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents the interior reed-cylinder, which is arranged at its circumference with twelve reeds representing the sounds of the chromatic scale, said reeds he- (Xo model.)

ing preferably set into recesses of the cylinder in such a manner as to be readily removed and replaced in case any one of the reeds should require cleaning or give out by use.

The head 0! the cylinder A is provided in line with its axis with a handle. button, or other deviee, a, by which the cylinder may be turned around its axis within the inclosing casing B, while the other head is arranged with a mouth-pieee, I), through which air maybe blown in let sounding the reeds. One head of the cylinder Aisprovidedwith thevisihletrichords ot' the diii'erent keys and their scale numbers, signatures, and clefs, while the opposite head shows the signature of any key and its keynote. At both sides of the reed-cylimler the notes and characters are arranged on circular statl's. These difierentcharacters are preferably stamped in relief into the metal covering of the reed-cylinder, or they may be engraved thereon, or printed on paper and pasted upon the cylinder, or arranged thereoirin anyother suitable manner.

The circumference of the inclosing casing B is provided with a number of square openings, (6, which are arranged in pairs and with intermediate transverse slots 6, as shownin Figs. 1 and i, respectively. The square openings (I serve for reading off the entire scale, with its necessary sharps or flats, which is stamped or engraved into the circumference of the reedcylinder A, as shown in Fig. 3, while the transverse slots 0 serve, in connection therewith, to admit the audible sounding of the chord corresponding to the key to which the indicator has been set. The slots 0 are arranged at such distances from each other as to represent the major chord of any key, there being a fourth slot by which the relative minor chord may be sounded when a covering slide-piece, O, has been properly set so as to open one and close the other of two adjoining slots, 0, in connection with which the slide-piece O is worked. The slide-piece U is guided in recesses of the casing B and connected by radial arms with the mouth-piece and handle of the reed-cylinder, or it is guided inside of the casing B, as 'desired, it being stopped when arriving in the proper position in either direction.

The circumference of the outer casing, B, is

further provided along one side of the opening (I and slots 0 with the scale-number and at the othersidewith the syllables of the Italian scale, do, re, mi, fa, 82c. Theheads of the casing B are provided with a sector-shaped opening, f, and a slot,f, at one side, and with two sector-shaped openings, 9 g, at the opposite side of the casing, as shown in Figs. 5 and 7. If. for instance, it is desired to know the key of any piece of musichavingthe signature of four flats, the indicator is turned until the four flats appear through rccessf of the casing at the end of the reed-cylinder which indicates the key of A-flat, the relative minor of which is F-minor, which will also be visible at the openingf.

The scale at the circumference of the cylinder shows the half and whole steps and indicates which tones are flat, while all tones that do not occur in the respective key are covered. The visible chord, appearing through the recess g ofthe casing both for major and minor, will be readily sounded by properly setting the slide-piece G. In this manner the device is capable of convenient use for a variety of purposes, mainly, however, for self-instruction in music, as it gives the transpositions from one key to the otherand furnishes every needed information as to the keys and scales quickly and easily without any trouble.

I am aware that a chord-intonator consisting of a reed-cylinder, slotted casing, and a mouth-piece at one end is a device well known to musicians, and I therefore lay no claim to the same, but simply to the additional features shown by my device.

Having thus described my invention, I claim as new and desire to secure by Letters Patent The combination, in a scale and chord indicator, of an interior reedcylinder, arranged substantially as described, with an exterior cylindrical casing provided with transverse slots for the egress of the air, recessed heads for exposing the entire scale, and mechanism for indicating at pleasure the major and its relative minor chord, all substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 1st day of September, 1881.

CHARLES H. HAUSOHEL.
