MUSICAL INSTRUMENT.
SPECIFICATION 'Orming part of Letters Patent N0. 519,737, dated May 15, 1894.
Application filed November 16, 1893. Serial No. 491,143. (No model.)
To a/ZZ whom, it may concern:
Be it known that I, FRIEDRICH ADOLE RICHTER, a subject of the King of Bavaria, residing at Rudolstadt, a city of the principalty of Schwarzburg-Rudolstadt, Germany, have invented certain new and useful Improvements in Musical Instruments, of which the following is a specification.
My invention relates to reed valves for automatic musical instruments, and has for its object to improve and simplify the construction of reed valves employed in the above described class of instruments. I attain this object by means of the mechanism illustrated in the accompanying drawings, in which- Figure 1 is an elevation partly in section of a form of reed valve hitherto in use. Figs. 2 and t are views showing reed valves mounted on a reed-box and having my improvement applied thereto. Fig. 8 is an elevation of a modification. Fig. 5 is a detail View of my improved reed valve. Fig. 6 is a detail view of the guide-plate so called. Figs. '7 and 8 are details hereinafter referred to.
The opening and closing of reed valves for automatic musical instruments has hitherto been accomplished, as shown in Fig. l, by
causing the points of the pivoted lever y supported by a suitable pivot oc and connected to the reed valves d, by wire 2, to be moved up and down by a perforated note-plate or a noteplate provided with elevations which is moved over said points.
It will be understood that the reed valve is moved by a spring, which, when the lever y is in its normal position, will be under tension, and will serve to open the reed valve when the lever y is allowed to move from its normal position by entering a perforation in the note-plate, or riding over an elevation, when the note-plate is provided with elevations.
According to my invention I actuate the reed valves by means of levers f having points a, which levers are preferably made of one piece and rest directly and are supported upon the spring tongueb of the reed valve d, (preferably having points f which pass through apertures in the spring tongue 12,) the reed valve d being held under tension by a spring c made integral with the spring tongue b. My preferred method of forming the springs for the reed valve d is to stamp out and bend up a tongue as b from a plate CZ having also integral therewith the spring c. The reed valves cover suitable valve seatsin the reed-box g in which are located the reeds e. The points a of the levers f proj ect through apertures lo in the guide-plate k. @ver these projecting points passes a note-plate m having perforations m of varying lengths, orelse provided with elevations (not shown).
The operation of the device is as follows: The normal position of the levers and reed valves is shown in Fig. 4, whereinV the point a projecting through the aperture 7c rests against the traveling note-plate m and holds the reed valve firmly against the reed-box and the spring c under tension. As soon as an aperture in the note-plate comes opposite the point of the lever, the tension of the spring c forces the point a through the perforation in the note-plate, raising the reed valve d and holding it open during the time that the aperture m is opposite the point a. This is the position of playing, and is shown clearly in Figs. 2 and 3. As a note-plate m continues to move, the edge of the perforationm will press against the inclined face of the point a and force it down, at the same'time moving the lever f and closing the reed valve d.
I may employ points a having a variety of surfaces, two of Which are shown in Figs. 7 and 8, in order to accomplish the closing of the reed valve d by a suitable cam action between the point ct and the edges of the perforations m in the note-plate.
I do not herein limit myself to the precise devices shown, as the device may be greatly varied by any skilled mechanic, without departing from the spirit of my invention.
What I claim, and desire to secure by Letters Patent, is-a l. In an automatic musical instrument, the combination of a reed-valve d, a spring c for supporting the same under tension, a tongue b integral with the spring c and bent up at an angle to the reed valve, a lever f having one end bearing directly upon the tongue b and supported thereby and having its free Ico In testimony whereof I have signed my naine to this specification in the presence of ro two subscribing Witnesses.
FRIEDRICH ADOLF RICHTER.
