Letters Patent No. 109,003, dated November 8,1870.

IMPROVEMENT IN REED-ORGNS.

The Schedule referredto in these Letters Patent and making part of the same.

To all whom it may concern.' i

Be it known that I, Honn'rro N. GOODMAN, of Syracuse, county of Onondaga, State of New York, have invented a new and usefulImproveir-ent in Reed- Organs, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing making part of this specification, in which- Figure l is a perspective view of my ilnpuoved reedboard, with thc cap or top board removed, and

Figure 2 is a vertical sectional view taken longitudinally of the reed-tubes.

Ihe invention relates to thzit class of reed-organs in which the reed is actuated by an exhaust instead of by a direct blast, and consists in forming a series Y being made in the same piece practically with the reed board, and also by being located on the lower or sounding-board, or, as it is sometimes called, the base of the reed-board. The third point gained is providing cach reed with a separate chamber, whereby its sounding wave is kept temporarily more distinct from and uniniiuenced by the wave from any other reed, and can therefore' be manipulated and modified as its own peculiarities may require.

In the drawingv A represents the lower or sounding-board of a reedorgan or melodeon of thc class in which the reeds are actuated hy al1 exhaust.

B is the intermediate or tube-board, provided with chambers B1, in which the reeds C are placed.

show the chamber, but in practice it is glued or otherwise fastened securely to its place.

F is a valve closing the orifice a in sounding-board A, over which the reed C is placed. The action of this valve and the exhaust-bellows to be used in connection with the reed-board is so well known to those familiar witluthe arts that I need not explain them in detail.

From the above description of my invention it will be seen that the forni and size of chambers I32 may bc varied to adapt them to the pitch of the corresponding reeds oi' to any other circumstances which may require a modification of either the volume or quality of the time. These variations may be made when the chambers are being cut, and then, should .further modifications be required, they can be effect ed by gluing suitable blocks into the chambers.

I do not-wish to confine myself to tlie construction of chambers which I have just described; that is, of gradations of size or of change iu form, to make them correspond to the pitch or other peculiarities of the reeds with which they are employed, for I regard these modifications as heilig in the nature of details by which my invention may be rendered more perfect in its operation.

The effect of these single chambers is materially different from that produced by the ordinary swell-box in recd-organs, as thc only function of this box is t0 mutiie the tone in a greater or lesser degree as the swellleaf or fold is more or less opened; but my chambers are permanent in their relation to the individual reeds and the characterl of the change effected by them, whether as regards increase in volume or modification in quality-is nearly the same whether used with or without a swell-box or modding-chamber, which is counected with and affects them all in common.

Having nowdescribed my invention,

That I claim as new, and desire to secure by Letters Patent, is

In a reed-organ which is operated by an exhaust the reverberatory-chamber B2 formed iu the reedboard, and arranged in rear of the reed-tubes, for con* ducting or modifying the sound-wave produced by the reed.

In testimony whereof, I have hereunto set my hand this 17th day of September, A. D. 1870.
