ATTACHMENT FOR MUSICAL INSTRUMENTS.l

SPECIFICATION forming part of Letters Patent No. 493,099, dated March 7, 189,3. Application lerl September 17, 1892. Serial No. 446,195. (No model.)

To all whom it may concern.-

. Be it known that I, WILLIAM LEINER, of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Attachments for Musical Instruments, of which the followingis a full, clear, and exact description.

My invention relates to improvements in musical instruments, and the object of my invention is to produce a simple device which may be attached to instruments such asAmerican harps or zithers, or analogous stringed instruments, which may be conveniently operated so as to change the key of the instrument to which it is applied, which may also loe made to change the key from a major to a minor, which is arranged to damp all the strings except those in actual use so as to facilitate easy and nice playing, and which may be removed from the instrument when a string is to be replaced or the instrument cleaned.

To these ends my invention consists in certain features of construction and combinations of the same, as will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings forming a part of this specitication, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a broken perspective view of a common form of American harp with myimproved attachment applied thereto. Fig. 2 is a broken vertical cross section on the line 2-2 in Fig. 1, showing in detail the constructionl of the cross bar andthe damping mechanism carried thereby. Fig. 3 is a broken lcross section on the line 3-3 in Fig. 5. Fig.

4 is an inverted plan of the cross bar which is applied to the instrument and carries the dampers; and Fig. 5 is a broken longitudinal section of the same, showing in detail the lever and slide mechanism for operating the vertically movable dampers used in changing the key ofthe instrument.

The harp is of the usual kind, and has the strings 11 extending across the top. On opposite sides of the strings and secured to the top of the harp are base pieces 12 having upwardly extending parallel arms 13,although the arms may be secured directly to the harp without the base pieces if desired. The sliding cross bar or damper bar 14. is held to move transversely across the strings and between the arms 13, this bar having a top piece 15 which projects slightly beyond the sides of the bar so as to form iianges against which the springs 16 may rest. These springs are of curved wire and are secured to the arms 13, and the tension of the springs is such as to normally raise the bar 14e and hold the dampers thereon out of contact with the harp strings. Near the ends ot' the bar and on opposite sides are openings or slots 17, and secured on the sides of thc bar in the upper portion of the openings are toothed racks 18, the teeth of which project downward and the racks are let into the bar so that the outer faces of the racks are iiush with the side of the bar; the distance between the rack teeth corresponds to the distance between the strings 11 of the harp.

Pins 19 are secured in the upper ends of the arms 13 and these pins project into the slots 17 and prevent the barfrorn being raised too high. On the bottom of the bar, near the center and at suitable intervals, are dampers 2O of felt or other suitable material, which are adapted to rest upon a portion ot' the strings when the bar is depressed and damp the same, the dampers being arranged so as to span regular intervals. Near the opposite sides of the bar and on the bottom are slides 21 and 22 which extend longitudinally of the bar and move in slideways 23 therein, these slides having on their under sides dampers and 2t)b which are adapted to be brought into contact with the strings of the instrument, as described below. The slides are held to the bar by screws 24 which project through longitudinal slots 25 in the slide, and the slides are held normally in position to bring the dampers upon the strings so as to form a majorchord when the strings are struck, by spiral springs 25, there beingaspring for each slide and each spring is arranged between one end of the slide and the adjacent end of the bar.

A lever 26 is secured to the slide 21 and extends upward to the bar 14, the lever terminating at its upper end in a finger piece 27, and a similar lever 2S is secured to the bar 22 and is provided at the top with a linger piece 29, the levers being held to slide respectively in slots 28 and 30 in the bar 14, as shown in Fig. 1. The bar is provided, in addition to the dampers above described, with small vertically movable dampers 3l which are arranged in line with the dampers 2O and which are adapted for use in changing the keys, these dampers being held normally out of contact with the keys andlying in holes 32 in the bottom of the bar. Each damper 3l has a vertical shank 33 and the shank and damper are raised by a spiral spring 34 which is held in a recess 35 in the bar near the top and presses upward on a collar 36 in the shank.

The upper end of the key presses against a slide 37 which moves in the slideway 38 near the center and top of the bar, and the slide 37 has notches 39 which, when moved above the shanks 32 of the dampers 31, permit the said shanks and dampers to rise. The slide 37 is moved by a lever 40 which projects upward and terminates in a key piece 41 above the bar 14, and the lever is held to move in a slot 42 in the top of the bar or rather in the top piece 15 of the bar. On the front of the bar is a table 43 indicating the several keys of the instrument, and a rod 44 is secured to one of the arms 13 and is bent upward at its free end to form. a pointer or indicator 45, and when the bar is moved the positionof this indicator, in relation. to the table 43, will indicate the key which will be formed, and this key will always be a major if the levers have not been used.

The operation of the bar in connection with the instrument will be understood from the following description z-A. chromatic octave consists of twelve intervals and if intervals 1,` 5 and 8 are taken together they form what is called a major chord, and by keeping the same ratio of intervals thekey note may be based upon any note and all major chords formed.y To this end the' dampers 20 are spaced so that when. the bar is pressed down, the pins 19 engage with the teeth of the racks 18,.v and the dampers 20, 201,20b and 31, cover all the strings but the first and eighth in each octave, and if a pick or ring is passed over the strings-a major chord will be voiced and thus, with the aid of the twelve notches in the racks, all major chords may be made.

The letters represented by the several strings are produced in Fig. 4 in a diagrammatic way, so that this may be better understood,and by reference to the said letters and to the dampers on the bar 14, it will be seen that all the strings except the C, E and G strings are damped. By pressing down the bar 14 and pushing the finger piece 27 and slide 21 to the left, the dampers on the slide 21 will be moved one interval, and as they have previously covered the second interval they will now expose said interval and cover the first,th us forminga diminished chord comprising the second, fifth, and eighth intervals. lf by pressing down the bar the finger piece 29 and slide 22 are pushed to the right, the dampers on the said slide will move one interval to the right and expose the fourth interval, which has been previously covered, and cover the fifth, thus forming a minor chord comprising the first, fourth and eighth intervals. lf the finger piece 4l and slide 37 l are pushed to the left, the dampers 31 normally cover the eleventh interval, will rise upward when the notches 39 of the slide register with the shanks of the dampers, and said intervals will be exposed, thus making the chord of the seventh, and the chord of the-instrument when struck will comprise the iirst, fifth, eighth and eleventh.

From the foregoing description it will be seen, without going into further details, that these dampers may be used in very many combinations so as to damp any desired strings and produce any desired key, and the dam pers, when in their normal positions, will when the bar is pressed down, cover the second, third, fourth, sixth, seventh, ninth, tenth', eleventh and twelfth intervals, leaving eX- posed the first, fth and eighth, ay major chord.

The instrument may be used to perform dierent styles of music such as instrumental, vocal accompaniments, dac., and as the keys maybe changed by simply sliding and pressing down upon the bar 14, the instrument may be very easily played.

Having thus described rn-y invention, I claim as new and desire to secure by Letters Patent- 1.
