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.
