'Leiters Patent No. 101,452, dated April 5, 1870.

IMPROVEMENT IN MELODY-ATTAHLENT.

The Schedule referred'to in than Lette To all persons to whom these premutxnuty come 'Be it known that 1, CARL lioennnnnu, a citizen of Sweden, but now residing at Boston, of the county of Suffolk and State of Massachusetts, have made a new and useful invention having reference to Melody-Attachments -for Key-board Musical Instruments; and do hereby declare the same to be fully described in the following specitcation and represented in the accompanying drawing, of which- Figure 1 is a longitudinal section, and

Figure 2, a transverse section of a melmlv-attachment, with -my invention applied to it.

1n the said drawing what is termed the "melodyattachment consists not only of a long, narrow, and shallow passage, A, and a series of valves, G C C, applied to 'its top and arranged as represented, but a series of organ pipes, ,ll l) D, provided with ducts leading to such valves.

Each of such valves has an operating stem, a furnished with a button, b, andan elevatingspring, c.

The passage A receives air from the bellows ot the instrument through an opening, d, and has a'elosingvalve, B, disposed in advance ofthe series of hipevalves C C C.

The valve B is also furnished with a stem, r, pro-l vided withv a lifter or spring, f.

To ythe said passage A, with its pipes, ducts, and valves, as described, constituting what is termed a melody-attachment for a key-board musical-instrument,1 apply another air-duct or passage, E, provided not only with an opening, y, to communicate with the opening d, but having a sexies of holes, h lt h, leading out of its top and underneath the valves c, each hole h being arranged directly under one ofthe said valves. I also apply to the passage E, in advance of the holes It, a valve or damper, i, hinged to the bottom of the passage, and furnished with a stem, k, which should connect with a pedal,

The several stems of the pipe-valves are to have keys applied to them, so as to be operated thereby.

The valves B and t' are to effect the closing of each of these passages A and E, as occasion may require.4

rs Patent and making part of the lame.

through its bottom and in rear of its nose-pieccfmf,and there is applied to the lower ends of the several pipes, so as to cover such holes l of them, a flap or valve, fm, it being hinged to the pipes.

On moving such valve downward on its hinge n,the whole series of holes may he opened.

This valve is a swell,applied directly to the pipes made with air-holes, arranged over such swell in manner as represented.

By moving the swell down, more or less, the tone of'the pipes, or those. in action at any time, may be pleasantly modied.

From the above it will be seen that when any oneof the valves 'c is depressed upon the bottom of the passage A, such valve, provided there be noanxiliary air-passage below it, will cnt od' communication with all the pipes in rear of it; consequently, while such valve may remain depressed for the purpose of sounding its pipes, none of. the other pipes in rearl can be sounded, but by having the auxiliary air-passage E, with its valve and ducts as described, air may be a1- lowed to flow into that part of the passage A which may be in rear of any valve that may be depressed in it.

Thus, while I retain the advantages of .the narrow duct A, I am, by my additions, able to avoid the difficulty above mentioned of actuating any pipe whose valve maybe in rear of' any one which luay be depressed.

l. claim, therefore- The combination of rthe auxiliary wind-passage E, its valves and air-ducts, as described, with the melodyattachment, composed of the passage A, its valves, air-ducts, and series of pipes, as set forth. the whole being to operate substantially as explained.

Also, the combination of the swell-valve m and the series of openings l, with the pipes D, arranged t-o operate as set forth GA RL FOGELBERG.
