SPECIFICATION forming part of Letters Patent No. 286,679, dated October 16, 1883.
Application filed January G, 1883. (No model.) Patented in Germany January 2l, 1883.

board, B, and casing C,for covering the valves, l place the springs, I bend one or both ends of the top or cover of the reed-chest having the usual openings, upon which the valves close. The valves 1 and keys 2 are also of the ordinary construction, the latter being pivoted in the usual manner upon a single rod 3, which passes through all of the keys and has bearings in the key-board. The springs 4, which serve to normally hold the valves in a closed position, are also, as is usual, placed in recesses 5 in the key-board, behind the keys. From this arrangement it will readily be seen that, in order to repair or readjust the keys, valves, or springs, it is necessary to expose the under side of the key-board and to obtain access to the recesses 5, and that when the key-board is attached in the ordinarymanner to or made a part of the reed-chest this can only be done by removing the top of the z'instrument, and then 'detaching the key-board from the casing of the reed-chest. To avoid this delay and trouble and the incident danger to the instrument, the key-board is made removable independently of the reed-chest, it being for this purpose provided with a hinge, 6, and latch 7, by which it can be secured in the position shown in Fig. 1 when the instrument is to be used, or swung to the position shown in Fig. 3 when it is desired to gain access to its action. By this arrangement it will be seen that access can be instantly had to any one of the keys, valves,`or springs, and that any one of these parts can be repaired without disturbing or disarranging any of the others and without the necessity of removing the top of the instrument.
The hinge 6 and latch 7 may be arranged at l and 3, or they may be arranged, as shown in Fig. 9, so that the keyboard shall swing backward, or, instead of a hinge and latch, two or more latches, catches, or other fastening devices may be used, so that the key-board can be entirely detached from the reedchest when it is desired to gain access to its action.
A part of the advantages just enumerated may be attained by making the l[op 12 of lthe key-board in a separate piece, as shown in Fig. 2, and so securing it to the body of the board in any suitable manner that it can be readily removed, or by making the back 13 of the keyboard separate and removable from the body.
By either of these constructions access can be readily obtained at any time to the recesses containing the springs, so that the latter can be removed or adjusted without removing the key-board; but these constructions will not, of course, facilitate access to the valves.
As before stated, when the ends of the springs 4 arebent so as to form spikes which enter the keys and the walls of their recesses, the springs are liable to turn so as to come into contact with the walls of the recesses, thereby causing imperfect action of the keys. To prevent this turning of the springs, and also to obviate the necessity of removing the keys from their pivots in order to remove and rethe springs, so as yto form quadrilateral loops 8, which iit squarely into the recesses 5, as shown in Fig. 5, in such manner as to always keep the springs in substantially a central position. One end of vthe springs, instead of being bent to aquadrilateral form, may be bent so as to form a projection, 9, as shown in Fig. 6, which enters a recess, 10, in the back of the key, so as to prevent the spring from moving toward the bottom of the recess 5. The keys may also be provided with central grooves, 11, 'in which the arms of the springs bearing against them will rest and by whichv these arms will be prevented from moving laterally.
The grooves 10 may be omitted if the loops 8 are made to iit tightly into the recesses 5, and both the grooves 10 and 11 may be omitted if the springs are provided with quadrilateral loops at both ends.
The springs 4, instead of being made of wire, as in Fig. 6, may be made of spring sheet-metal, as in Fig. 8'. The loops 8 need not be complete quadrilaterals, as shown, it only being essential that two bearing sides be provided to rest against the sides of the recesses.
Withthis construction it will readily be seen that by pressing the arms of any one of the springs together with a pair of forceps it can be easily removed fron and'replaced in lits recess. f

The combination, with the reed-chest A, the top of which is provided with the valveopenings, of the key-board B, carrying the valves, keys, and key-springs, and means for detachably connecting said key-board to the IOO the recesses and prevent the bodies of the springs from turning so as to come into contact with said walls, substantially as described.
