' UNITED STATES PATENT OFFICE,
JACOB IIESSLRR, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE IV. IV. KIMBALL COMPANY, OF SAME PLACE.
REEDHORGAN.
SPECIFICATION forming part of Letters Patent No. 388,490, dated August 28, 1888.
Application filed March 24, 1888.
.To all 107mm/ it may concern:
Be it known that I, JACOB I-IEssLER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois,
5 have invented certain new and useful Improvements in Reed-Orgaus, which are fully set forth in the following specification, reference being had to the accompanying drawing, forming a part hereof, and in which the figure io represents a vertical section across theinstrunient cut through the center of the valve and cells closed by it. v
The object of my invention is, first, to make a more resonant sounding-board; second, to t5 enlarge the air-chamber between the reed and valve, so as to give more room for the free vibration of the reed and thereby produce a more voluminous sound, and, third, to enlarge the air-chamber back of valve-seat to zo ward the bellows. To accomplish this end I make the sounding-board a as thin as possible, and strengthen it at the reed-cells by attaching a piece, in, running lengthwise of the instrument under the reed-cells. Said board m 25 may be made quite thick, so as to increase the vertical depth of the valve air-chamber Z under the reeds as much as possible7 and thereby give greater freedom ol' air-space and less resistance to the vibration ot' the reed.
The reed-cells c c c2 communicate directly with the valve air-chamber d, as shown, and are provided with mutes i z" i2. The valve e,
Serial No. 265,336. (No model.)
tracker-pin 71, and springj are constructed an d applied in the usual way.
The bottom I) of the air-chainberf is made heavy, as are also its lateral sides, as 7a and Z, so as to more completely retain the vibration in the thin sounding-board a. rlhe arrows show the direction of the aircurrents through the passages and air-chamber outthrough the opening g into4 the bellows. The air-chamber f, by this construction, is also enlarged at the side where the air escapes into the bellows, and through this Construction gives an additional t'reedom to the air-eu rrents, and through this better vibration to the reeds.
Vhat I claim isl. In a reed-organ, a thin soundingboard, a, provided with a board, in, on its inner or under and valveseat side, deepened-valve airchaniber, and an enlarged wind-chest under said thin board a and discharging end, substantially as specified.
2. In a reed-organ, a thin sounding-board, a, provided with a board, m, on its inner or under and valve-seat side, deepened-valve airchamber, enlarged wind-chest under said thin board a., and discharging end and rigid and enlarged walls Z) la Z, substantially as specified.
