To all whom t may concern.-

Be it known that we, JOHN COCCHI and FRIEDRICH AUGUST ZEITLER, both residents of Berlin, Germany, have invented an Improved Mechanical Attachment for Musical Instruments, (for which we have obtained the following patents: in Germany, No. 51,235,- dated August 6, 1889, and No.'55,710, dated January 23, 1890; in England, No. 5,862, dated ro April 17, 1890, and in Spain, No. 10,872, dated May 31, 1890,) of which the following is a specification.

This invention relates to an attachment for musical instruments-such as pianos, harmoniums, bc-by means of which a perforated music-sheet is made to operate the keys and produce thesound. -Themusic-sheetbymeans of suitable lever connections operates upon a set .of bellows that by expanding or conzo tracting in turn operate upon the keys,and

consequently upon the hammers.

Our attachment is such that it may be applied to the existing construction of musical instruments without requiring alterations of 2 5 the actions. l l a In upright pianos and similar Instruments where the attachment is placed under the keyboard it may be made entirely removable.

In the accompanying drawings, Figure 1 is 3o a vertical longitudinal section of an upright piano provided with our improvement; Fig. 2, a vertical transverse section with the lidA raised; Fig. 3, a longitudinal section of the piano; Fig. 4, a vertical transverse section with the lid A lowered; F1gs.5 and 6, sectional, side, and end Views of the mechanism operated by the music-sheet, showing lever F engaging a'perforation of such sheet.

Figs. 32 and 33 are details ofthe valve b3, 7o showing it, respectively, closed and open; and Fig. 34 is a section on line P3 P3, Fig. 32.

The letter A represents a lid beneath the key-board B and turning on trunnions d, journaled in the frame of the instrument. This lid carries on its face the leversaa,op erated by the bellows, and the lever F, acted upon by the perforated music-sheet and the note-leaf motor E. At its back the lid carries the bellows D D', with the posts GH,and the 8o bellows J K and connecting-ports e, Fig. 4. The levers a a', which are operated by the bellows, in turn operate the keys L Lof the piano by Ineans of intermediate levers b, Fig.

2. These levers are pivoted to a rail g, and

at one end are adapted to be engaged by the levers a, while at the other end they operate pull-d0wns 7L, that in turn act upon the keys. The bellows D D levers a a', and levers b extend horizontally from side to side of the 9o piano-case beneath the'keys, as will be readily understood. The levers F, however, to` gether with the music-leaf feed E, extends from the front to the rear of the instrument, Fig. 2.

When the mechanism is to be put into action, the lidA is swung into its horizontal position, in which it will be maintained by catches le, Fig. 1. These catches may be disengaged (when the lid is to be swung down) roo by means of a push-button l, acting upon pair of levers m o, connected by a rod n, and in turn acting upon the catches lo to spread a In Fig. 22 the connection between the parts b q is shown to be made by a short elbowlever t2, which replaces the disk t.v

Of course the mechanism above described may be readily reversed, so that the notes are not sounded by contraction, but by expansion of the bellows. As the surface of the lid A for the entire width of the instrument may be utilized for the support of the sheet O, such sheet may be made in the form of a band` or it may be made endless orsectional. W'hen sectional sheets are employed, we prefer to connect the sections by the joint shown in Figs. ll and 12. Here the sections O' O2 of the music-sheet are connected in such a manner that the inotion of the music-sheet will not have a tendency to injure the joint, but that such motion will, ou the contrary, have the effect to bind the sections more closely together. 'lo this etfect the sections O' O2 are connected by strips P in the following manner: lhe strip P s placed below the joint of sections O O2, and is then bent upwardly at both ends to pass through such sections. The ends are then attened out upon the surface of the sections O' O2, both fiattened ends P' P2 extending in the direction of the motion of the sheet. Thus the ends will be kept out of contact and an even feed of the sheet maybe had.

What we claim is* l. The combination of a musical instrument with a folding lid A, a set of levers secured thereto and adapted to be engaged by a music-sheet, a set of bellows acted upon by the levers, and a set of litters operated. by the bellows and adapted to act upon the keys, substantially as specified.

2. The combination of bellows D D' with valve-rods o, operating both of said valves, and a set of levers for operating the valve-rods,substantiall y as specified.

3. The combination of bellows D D with ports G Il, valves M N, and with valve-rods 1f,

having buttons tu, that are adapted to engage valves M, and levers adapted to operate the q', valves b2 b3, operated thereby, and the bellows D', substantially as specified.

7. The combination of bellows D D' with drawer Q', and the valves b2 b3 and levers F', contained within such drawer, the drawer being adapted to be partly or completely withdrawn, substantially as specified.

S. The combination of lever i with lifterf, lever f2, Valve V, and pedal-levers k' k2, substantially as specified.

9. The combination of music-sheet O, having perforation with levers F' c, rods q, disks t', litters f', levers f2, and pedal-levers k' k2, substantially as specified.

l0. The combination of a sectional musicsheet O O2, with connecting-strip P, passing through the same and having its ends P P2 upset on the same side of the music-sheet, so as to extend in the same direction, substantially as specified.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
