Letters Patent No. 97,101, dated November 23, 1869.

IMPROVEMENT IN COMBINED BED AND MUSICAL-INSTRUMENT BOARD.

The Schedule referred to in these Letters Patent and. making part of the same.

To all whom 'it may concern Beit known that I, JOHN MCDONALD, of thc city, county, and State of New York, have invented a new and useful Improvement in Combined Bed and Key-Board Musical Instrument; and I do hereby de clare that thc following is a full, clear, and exact description thereof', which will enable others skilled in the art to make and use the same, reference heilig had to the accompanying drawings, forming part of this specification, in which Figure l is a vertical section of my improvedl device opened out to serve as a bed.

Figure 2 is the same view as fig. 1, but showing the device closed.

Similar letters of reference. indicate corresponding parts..

My invention has forits object to furnish a key board musica-l instrument, which shall he so coustructed, that it may be opened up to serve as a bed,

and which, when closed, shall have every,appearance of, and may in fact be a real instrument, suitable to be placed in a parlor or sitting-room; and

1t consists in constructing the case ot' a key-board instrument, in such a way that it may receive a mattress or other bedding, and may be opened up to serve as a bed.

Ais the case of. the instrument, which, in the. drawing, is represented as being a melodcon, with a case somewhat similar to that of' an upright piano.

B are the keys, whichare covered with a hinged lid or cover, C, and beneath which are formedthe windchest and bellows E.

E are `the treadle-rods, the upper ends of which are connected with or rest against the arms or levers ll of the bellows.

The treadle-rods E pass through guards or guides a', attached to the case A, so as to keep them always in their proper position.

The treadle-rods E should also be provided with pins e', or other stops, to prevent them iiom droppingr out while the case is being raised and lowered, and which should be so arranged as not to interfere with the propel' operation of the said rods when the instrunient is being played upon.

F are the treadles, which ar'e pivoted to supports, permanently attached to the base G of the case,- and which are provided with springs H, to hold them in proper position when released ii'om the treadle-rods E, said treadles and trezulle-rods being so arranged, that when the case A is raised into a vertical position, the lower ends of said treadle-rods may come into proper position upon the said treadles.

The side edges of the ease A, near theirlower ends, are pivoted to th stationary sides I, as shown in figs. 1 and 2, so that when the said case A is turned down into a horizontal position, as shown in fig. 1, it may be at a suitable height for a bed.

The frec end of the case A, when turned down into a vertical position, is supported by legs J, pivoted to its sides, as shown in iig. '1, ,in such a way that when the lsaid case A is raised into a vertical position, the said legs J may be turned inward, as shown in fig. 2, out of sight and out ofthe way.

As the case A of a musical instrument cannot be conveniently made of such a height as the full length of a bed, a separate part, K, is pivot-ed to the rear lower part of the stationary sides I, in suclra position that when the case A and part K are turned down into horizontal position, they may be upon the same horizontaldplane, where they may bc scoured to each other by pivoted buttons le', or sliding bolts, as may be desired`or convenient, said buttons or bolts being attached to one of said parts A K, and catching upon the other part.

' The inner sides ofthe cases A and K are furnished with slats, to support a mattress or other bed, in the ordinary manner, and with elastic or other straps, to keep the said mattress or bed in place upon them.'

The-mattress or bed should be made in two part-s,

d to keep it from being injured when the cases A and K are turned up into vertical positions.

, The front part of the top L, of the case, should be hinged to the rear \part of said cover or top, so that by shutting down over the case A, it mayfasten said case A securely 'when raised into a vertical position.

For the convenience of those who wish to practise fingering only in their rooms, the case A may be provided with dumb keys, thc operating parts of the in strurnent being omitted.

Having thus described my invention,

I claim as new, and desire to secure .by Letters Patcnt- 1. The combination of folding bed, upright frame, and l ey-board, when said key-board lis permanently connected with the said folding bed.

2. The combination of guides and stops with the treadle-rods E, to compel them to alwaysv drop into position upon the treadles F when the case A is raised into a vertical position, as herein shown and described, and for the purpose set forth. i

3. The combination of springs H with the treadles F, to hold them in proper position to receive lthe treadle-rods E when the case A is raised into a verti- -cal position, as herein shown and described, and for the purpose set forth.

The above specification of my invention signed by me, this 27 th day ot' September, 1869.

XVitnesses: JOHN MCDONALD.
