MUSICAL WIND INSTRUMENT.
Specification of Letters Patent.
Patented Aug. 15, 1905.
Application filed December 2, 1.904. Serial No. 285,182.
T0 all Luk/mt it mamy concern:
Be it known that I, JULiUs SCHWARZ, a citizen of Germany, residing at New York city, Bronx, county and State of New York, have invented new and useful Improvements in Musical Wind Instruments, of which the following is a specification.
This invention relates to a musical wind instrument of novel construction and designed to produce musical sounds by exhausting air from pipes and by blowing it into the same by means of a common nozzle.
In the accompanying drawings, Figure l is a longitudinal section through one of the cells of a musical wind instrument embodying my invention. Fig. 2 is a longitudinal section on line 2 2, Fig. l; Fig. 3, a cross-section on line 3 3, Fig. l; Fig. 4, a perspective view of a mouth-harmonica embodying my invention; and Fig. 5, a longitudinal section, partly broken away, on line 5 5, Fig. 4.
1n carrying out my invention amouth-harmonica or similar musical wind instrument is divided into a series oi' cells of the construction more fully illustrated in Figs. l to 3. Each of these cells has a separate mouthpiece, and by exhausting air therefrom an organpipe contained within one compartment of the cell is sounded. By blowing air into the same mouthpiece a second organ-pipe contained within a second compartment of the cell is sounded, the construction being such that when one of the pipes is in action the second pipe is out of action.
The letter A represents the cell of the mu- Sical wind instrument, which is divided by longitudinal partition a and transverse partitions a' a into a front air-chest I), a rear airchest c, and a pair of chambers Z and e between said chests.
Vithin the chamber Z is contained a pressure-pipe f, the wind-receiving end or footf of which is fitted into an opening of front partition a', so that air blown into front chest will enter the pipe. Opposite to the rear of pipe f the rear partition a2 has an air-outlet a3, controlled by a rearwardly -opening valve g.`
Vithin the chamber c is contained a suction-pipe t, the wind-receiving end or foot /L of which is litted into an opening in the rear partition a2, so that the pipes f and /t are reversely mounted. The interior of pipe It communicates, by means of its aperture LZ, with the chamber e, so that it' air is exhausted from the front oi` such chamber a sheet of wind will be drawn from rear chest c into pipe /t and out through aperture 7a2, so as to sound the pipe. Opposite to the front of pipe /t the front partition a has an air-inlet ai, controlled by a 'forwardly'opening valve The front chest has a nozzle or mouthpiece j', by which air may be exhausted from the chest or blown into the same. The rear chest c communicates `permanently with the atmosphere by a port a5. This rear chest serves more particularly for protecting the rear valve g and may be omitted, if desired.
If air is blown into nozzle j, valve c' will close to cut oli" chamber c from chest and prevent the sheet of wind from entering the former. The wind will thus all pass into pipe f and out of its aperture f2 (and with open pipes through the back thereof) into chamber (Z, from which it will escape through open valve g, chest c, and port a5. In this way pipe f will be sounded by pressure, while pipe /t will remain mute.
It air is exhausted through nozzle j, valve f/ will close to cut oli chamberrcl from chest c, and consequently from port a", and thus prevent the sheet of wind from being drawn into chamber (Z. The wind will thus all pass into pipe /r and out of its aperture /L2 (and with open pipes through the front thereof) into chamber c, from which it will pass through open valve fz and chest 7) into nozzle j. In this way pipe /t will be sounded by suction, while pipe f will remain mute.
It will thus be seen that by forcing air into or exhausting it from the chest o, or, in other words, by changing the tension of the air in said chest, either the pipe f or the pipe L will be sounded, the one by pressure and the other by suction.
In Figs. 4 and 5 is illustrated a mouth-harmonica B, divided by means of the transverse partitions into a series of cells A, each being of the construction above described and each provided with its separate mouthpiece j. Thus by applying either air-pressure or suction to one of the mouthpieces but a single note will be sounded without necessitating the manipulation of valves.
lVhat I claim isl. Amusical windinstrumentprovided with a pair of reversely-mounted orgairpipes, and means common to both pipes for exhausting the air from one pipe and creating a blast in the other pipe, substantially as specied.
3. A musical wind instrument divided into a plurality of cells, an exhaust organ-pipe within each of the cells, and means for separately exhausting the air from each of the cells, substantially as speciiied.
