CHARLES SANGALLI,

or NEW YORK, N. Y..

Letters Patent No. 84,844, dated December- 8, v1863.

HAND-SUPPORTER PoR PIANos, acc. Y

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

To all whom it 'may concern:

Be it known that I, CHARLES SANGALLI, of' the city,

county, and State of-New York, have invented a new and improved HandSupporter for a Piano, Organ, or similar instrument; and I do hereby declare that the following vis a full and exact description thereof, referencebeing hadto the accompanying drawings, and to the lettels of reference marked thereon.

The nature of my invention consists inl providing a piano, organ,I or other similar instrument, with a handsupporter,which can at any time be'attached.ordetaehed without injuring the' instrument, as hereinafter described.

'lo enable others skilled Ain the'art to make and u se my invention, I will proceed to describe its construction. and operation,

Figure l represents the hand-supporter in a full-view and elevated position. The red lines show the wooden 'frames of the instrument, to which are attached the braces S S, which maintain the hand-suppolter above the key board. B l are supports, which slide along the hollow rods A, by means ofthe friction-rollers O C. 'lhetwo hands are placed into the stirrups I I, which selve as aresting-place for the same, lea-vi n g the fingers free to action. These stiirups can be made larger'or smaller, to suit the dimensions of the hands, by means of the screw D, upon whichmove the nuts O O".

`J J are elastic bands, which can be raised or lowered through the buckles K K, or in any, other appropriate manner. P P are flat plates, (which can be covered l with'leather, or any other fabric, so as -not to injure the polished part of the instrument,) to receive the pressure of the screws E Figure2 shows the hand-supporter-in a transversal section, passing through the instrument 'and apparatus. The screws E are usedto fasten the hand-supporter to the upper frame of the instrument. G and H are two plates, which are used to maintain the position which Iis desired tobe given to the hollow rod A, which shown in a section, and which can slide upon the wholelength between the screws E and P. "I"he other details of the construction are indicated by thesamefletter's which are in iig. 1, but the hand is seen in the stirrun I, upon the keys ofthe instrument. v v

Figure 3 is the same hand-supporter, fastened-to the lower frame. ofthe instruments, formed below theA keyboard. I n this position the stirrup I I does not serve 'for the suspension of the. hand, butas a rest to the wrist, as shown by the position'of the hand in that figure.

` Figure 4 shows a full view of' the hand-supporter, placed in the position indicated in iig. 3, -serving for a rest to the wrist. I'n this figure, the brace S, with the plates G H, the' screws E F, the nuts 0" O",

and the counter-plates P P, are not shown.A The frame B is placed upon the hollow rod A, by means of the two friction-rollers C C. The stirrup I is supported by'means ofthe small pivot X X, and is movable. This view is the same as indicated in iig. 1, with the difference, that in the stiirup I, the elastic bands J J, which are seen in the interior, serve to rest the wrist, instead of suspending the hands.

' What I claim as my iuveution,fand desire to secure by Letters Patent, is-

The apparatus hereinabove described, or its equivalent, suspending the hands or resting the wrists, withouthindering the free movements of the fingers, and keeping thereby the hand or wrist, and, in consequence thereof, the lfingers upon the key-board, in the position desired, at the same time unhindering all the motionsv required to be made to use the same, and to play upon an instrument, as above described.
