HENRY JAESOHKE, OF SCIY LOUIS, MISSOURI.

COMBINED MUSICAL INSTRUMENT AND STOOL.

SPECIFICATION forming part of Letters Patent No. 270,075, dated January .2, 1888.

Application filed August 16,1882. (No model.)

To all whom it may concern Be it known that I, HENRY JAESCHKE, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improved Combined Musical Instrument and Stool, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in Which Figure 1 is one-half in rear elevation and one-half in vertical section on line 1 1, Fig. 2. Fig. 2 is a transverse section taken on line 22, Fig. 1, with the key-board open. Fig. 3 isa detail view with the key-board in its closed position and Fig. 4 is a similar view with the keyboard in its open position, which brings the back ends of the keys into engagement Fig. 5 is a top view with half of the top of the case removed and the key-board open. Fig. 6 is an enlarged detail vertical section taken on line 6 6, Fig. 1.

My invention relates to a musical instrument to be operated by the feet, on which the bassnotes of a common organ can he played, and,

thus it can be used to accompany any kind of hen in use the operator sits on the case of the'instrument, and it can thus be used as a stool or bench when the same operator is playing it and a piano or organ or other musical instrument. When not in use the key-board can be closed up and secured in place by suitable springcatches, giving to the instrument the appearance of a rectangular box, which can be used as a bench in any part of the room, thus becoming an article of furniture.

My invention consists in the novel arrangement and construction of parts hereinafter fully described and claimed.

A represents a rectangular box or case, the back being provided with panelsto allow the escape of the sounds, the front B of which forms the key-board of the instrument, which is pivoted at'O to the front lower corners of the ends of the case, so that it can be opened out into the position shown in Figs. 2, 4, and 5 and rest upon the floor.

To the key-board, near its hinged end, is secured a strip, D, and vertically above this, secured to the sides ot'the board, is asecond strip, 1*]. The inner ends of the keys B fit between these strips, and are connected therewith by pins F, which pass through longitudinal slots in the keys. Suitable felt cushions are placed between the keys and the strips, as shown. The inner ends of the keys have projections G, with upturned ends or teats H, which bear'respectivelyagainst the under sides of the valveoperating levers I, which are pivoted by their rear ends at J to a strip, J, which is made fast to the ends of the case. It will thus be seen that when the outer ends of the keys are depressedtheir inner ends will raise the valves through means of the levers. The outer ends of the keys are supported by springs 13?. (See Fig. 2.) The black keys, which would correspond with the black keys ofan organ or piano, arelower than the white ones, buthave upward projecting ends, which extend above the white keys, (see Fig. 2,) so that either can be operated without operating the others.

The instrument operates by air being sucked through the reeds by means of bellows, which are preferably made in pairs K, as shown, each constructed as follows:

L is a partition-board extending all the way across the case from end to end, and inclined vertically, as shown in Fig. 2. It is secured to the case, and its lower end comes against a rectangular housing, M, in which the reeds are located.

M is a strip connecting the top of the lions ing and the inclined partition-board. (Ste Fig. 6.)

In front of the partition-board, and connected therewith by suitable flexible material, (see Fig. 2,) is a board, N, and toits rear, and similarly connected therewith, is another board, N, to which the operating-leverO is connected by straps, O, which pass over pulleys or rollers 0 secured to the top or back of the case. There are two of these boards N and two N, which form the double bellows. The lever is fulcrumed at 0 to the case, at a point about midway between the straps O, and thus when it is operated it will act alternately on the bellows K K. When the boards N are pulled out by the lever they are forced back by V- shaped springs P, located between them and the back of the case. (See Fig. 2.)

Instead of hinging the boards N to the case by their lower ends, Isecure arms N to them, which are pivoted at their lower ends to the extreme lower part of the case, and I thus increase the radius of the circle upon which they move.

WVhen the bellows are worked and the valves raised, as hereinafter described, by operating the keys air is drawn through the reeds, as shown by the arrows, (see Fig. 6,) passing through an opening, L, in the partition-board L, and then back through another opening, L in the board. (See Fig. 2.) When theboards N are forced back by the springs the air in the bellows escapes through flap-valves N on the back of the boards.

Q are set-screws on the inner ends of the levers I, which have cushions Q on their upner ends, which, when the keys are depressed, come against stems R, depending from the outer ends of valves R, which cover openings in the top of the housing M. The stems are guided by projections or strips It on the back of the housing,through which they pass. The front ends of the valves are guided by pins R extending up through them from the top of the housing. The valves are held down, except when raised by the keys, by springs R secured to the partition-board. (See Fig. 6.) The springs are removable, so that by detaching them the valves can be raised vertically and removed.

S are reeds secured to frames S in the ordinary manner. The frames are secured to the back wall of the housing in frontof openings T in any suitable manner. (See Figs. 6 and 7.)

To tune the reeds I pass a set-screw, 8, down through the overhanging projections S of the upper ends of the frames S. On the lower ends of the set-screws are nuts 8, which bear against the reeds, as shown, and by turning the screws the nuts will be moved up or down and their points of bearing on the reeds lengthened or shortened, thus limiting or increasing their amount of vibration.

The boards N are held away from the parti' tion-board, when in their normal positions, by

V-shaped springs N (see Fig. 2,) and to prevent this board destroying or breaking some of the parts by too violent an operation of the lever O, or when the lever is worked and the keys not operated, so that air cannot enter through the valves, I make openings through the boards and cover them with flap-valves N on the outside, and put pins N in the partition-board, (see Fig. 2,) so that when the boards Napproach the partition-board the pins will strike the valves and open them, allowing theairto rush in and supply the vacuum.

Ifdesired, the bellows can be worked by suitable springs, which would be wound up similar to a cloclcspring, instead of the lever.

If desired, the operating-lever may be connected by suitable means to a second lever, which would be within reach of the player, so that he can work the bellows. Instead of reeds, strings may be used, similar to an upright piano.

I claim- 1. A combined musical instrument and stool, consisting of music-stool having a side hinged to turn down, and foot-keys and levers for playing the instrument, as set forth.

2. Acombined musicalinstrumentand stool, consisting of a case, A, hinged side B, footkeys B, pivoted to said side,having extension G, provided with upturned ends II, levers l, hammers Q, vertical rods 1%, horizontal valves R, depending reed-box M, reeds S, bellows K, and bellows-operating lever O, as set forth.

3. In a musical instrument, the boards N of the bellows, having arms N on their lower ends, by which they are connected to the lower part of the case to increase the radius of their circles, as set forth.
