To aZZ whom, it may concern: written by figures or any other method, and Be it known that I, ARTHUR M. PHELPS, a without the aid of any chart or figures citizen of the United States, residing at Seaplaced in connection with the strings.

These cushions are formed provide an attachment for stringed instruof felt, rubber, or any other material adapted ments which may consist in part of an interfor the purpose, and they project from the 5 changeable muffler or dampingrollerwhereby surface of the roller in the same vertical 5 a series of rollers containing various melodies planes with the strings of the instrument, so and chords may be attached and detached at that when said roller is turned to bring the will, enabling a person to easily perform any series of cushions directly over the strings, melody that a certain roller may be arranged they will press upon the latter with sufficient 50 to produce without the aid of notes, or music force to prevent them from producing musical ICO tones. The series, or each series of cushions when a plurality of such series is used-is arranged in reference to the strings, so as to muffle or damp all the strings save those required to sound inorderto produceamusical chord or a given series of notes in a melody when the fingers or a pick or similar instrument is swept across the wires. It will be readily seen and understood how, by providing the roller with several series of such cushions around its surface each series being properly arranged with reference to the strings, and by giving a rotary movement to the roller, a series of musical chords will be produced by running the fingers or the plectrum across the strings as each series of cushions come in contact with the wires. Any one chord may be produced as many times as desired by holding the roller stationary with the properseries of cushions resting upon the strings, and sweepingthe pick across them as many times as necessary. Thus a roller may be provided with ainumber of series of cushions that will enable any one to produce the major and minor chords of any one or all keys, or any chord known in harmony. When two or more adjacent strings are to be muffled it is preferable to use one cushion instead of several small ones.

In order to enable one to produce a certain chord at once, I have provided a pointer 6, mounted on the roller to revolve the same, moving over an index disk or strip 7, on one of the supports 8. This index disk, or strip shows at a glance what chords the particular instrument is capable of producing and by revolving the roller so as to have the pointer rest over any one letter on the disk for instance O, and running the plectrum across the strings, the chord of C will be produced, and the same with the other letters. Of course letters or any characters preferred can be used on the index.

If preferable, the index disk may be attached to the roller and the pointer be attached to the support 3 or body of instrument. In either case the registering is the same to produce the same result.

When the pointer stands between any two letters on the index disk or strip, the strings are all free from contact with the cushions and any number of adjacent strings can be thus sounded very rapidly. I may cover the damping roller with a shield or housing 8 to hide from View the series of cushions and also prevent their being damaged from any cause. This shield is cut away at the index end so as to provide spacefor pointer 6 to revolve. This end is provided with small projections slotted to engage small pins which-support said shield at that end. The other end of the shield is provided on each side with a small hole, or slot, that engages two small pins which support and hold that end. This is a simple means of attaching the shield as it can thus be put on or removed at once, though of course any other suitable way can be employed; or, if preferred, the shield may be left off entirely. It is intended to be'used only with an attachment that produces certain chords the roller of which is permanently attached to it, and not with an attachment having an interchangeable roller, as it would hinder or retard the rapidity with which a roller could be'detached from the instrument and another attached, though'if desired it can be supplied with either style of attachment.

Under the strings of the instrument in suitable proximity to the roll, is placed a scale chart 9, consisting of a series of letters and figures placed immediately under the strings, the former, being used to indicatethe pitch of each string and the compass of the instrument, and serves as a guide should the instrument. .be played by note, and the latter serves as a guide in performing music written by the figure method.

In addition to the above series-of letters and figures the chart containsa series of columns of letters, there being one column for each full chord on the instrument. At the head of each column isaletter showing what chord the column represents, as, for example, if the instrument produces three chords say 0, F and G there will be three columns headed O, F and Gland in the column will be placed under each string that sounds in that chord the letter 0 showing just what strings constitute that chord and can be playedwhen the pointer is over 0 on the index disk. In column G will be indicated by letter G all the strings that constitute that chord, and that can be played when the pointer is placed over G, and so on with all the keys of the instrument no matter how many there may be.

In Fig. 4 I have shown one way in which the muffler roller is detached from the supports 3 when the attachment is arranged for interchangeable rollers. This interchangeable system is intended to be used when various rollers are prepared to either produce various chords, or contain a complete melody.

From mydescription of the operation of the instrument it will be seen how easily the series of cushions may be so arranged around the circumference of the roller in reference to the strings, that they will produce any melody or melodies, in the manner heretofore described. I show a simple form of attaching and detaching the roller though any suitable method can be used. An instrument can contain two rollers if preferable, one roller having set chords and permanently attached to the instrument and the other roller being interchangeable for producing melodies or special sets of chords. The roller 2, may be formed of wood, metal, or any suitable material, and it may be hollow or solid and where buta few series of cushions are used, the roller need not be entirely circular, a simple segment being used as shown at Fi 5'. The cushions are preferably glued to the IIO surface of the cylinder, but may be attached in any suitable manner.

My invention provides an extremely simple, cheap and easily operated attachment for stringed instruments which is capable of an indefinite variation of the music that can be produced thereby, and which enables any person without a knowledge of music to easily play the instrument. The simplicity of construction of my attachment makes its operation noiseless, there being no movable pushbars, triggers, or springs, or other devices to rattle, or screech, which always tend to mar the melody of the instruments on which they are used.

hat I claim is 1. A stringed musical instrument provided with a muffling attachment consisting of a roll having a number of longitudinal series of cushions upon its face, said cushions being of substantially uniform thickness and having their outer faces concentric with the face of the roll, the several series of cushions being arranged to muffle certain strings and produce a series of successive chords, or a complete melody, by turning the roll in the same direction, or in opposite directions, substantially as described.

2. An attachmentforastringed instrument, consisting of a roll journaled in suitable supports and extending across the strings out of contact therewith,its surface being provided with cushions arranged in a number of longitudinal series, said cushions being of substantially uniform thickness and having their outer faces concentric with the face of the roll, and means for revolving the latterintermittently in one, or both directions, substantially as described.

3. The combination with a stringed instrument of a roll journaled in suitable supports and extending across, but out of contact with the strings, its face being provided with cushions of substantially uniform thickness arranged in a number of longitudinal series each concentric With the roll, and in such manner as to muffle certain strings, means for revolving said roll intermittently in one or both directions, and an index consisting of a series of letters arranged concentrically with the roll and a finger which registers at each movement of the roll with one of the letters to denote the key of the chord which may be struck in said position of the roll, substantially as described.

4. An attachment for a stringed instrument, consisting of a removable roll journaled in suitable supports and provided on its face with cushions of substantially uniform thickness their outer faces being concentric with the face of the roll, said cushions being arranged in such manner as to muffle certain of the strings, means for turning the roll intermittently in one, or both directions, and an index consisting of a series of letters arranged concentrically with the roll and a finger which is caused to register with one of said letters at each intermittent movement of the roll, to denote the key of the chord which may be sounded at each movement, substantially as described.

5. An attachment for a stringed instrument, consisting of a roller journaled in suitable supports and capable of turning intermittently, throughout a complete revolution, or through any part thereof and in both directions, its face extending across and near the strings, and provided with one or more longitudinal series of cushions of substantially uniform thickness having their outer faces concentric with the face of the roll, and adapted to muflie certain'of the strings, and a housing to inclose the roll, said housing and roll being removable and replaceable, substantially as described.

In testimony whereof I have hereunto set my hand andaftixed my seal in presence of two subscribing witnesses.
