IMPROVEMENT IN REED-RGANS.

Specification forming part of Letters Patent No. l 70,078, dated November 16, 1875; application iiled l September 6, 1875.

To all whom it may concern:

Be it known that I, HonA'rro N. GOODMAN, of Syracuse, in the county ofV Onondaga and State of New York, have invented certain new and useful Improvements in Reed-Organs; and I do hereby declare .that the following is a full, clear, and exact description thereof, which will lenable others skilled in the art to which it pertains to make'and use the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon, which form a part of this specification.

Figure l is a perspective view of an organ embodying my improvement. Fig. 2 is a vertical transverse section of so much of an organ as is necessary to illustrate the invention, and Fig. 3 is a vertical longitudinal section of the same, taken on line a: y, Fig. 2.

It is frequently urged against reed-organs (or cabinet-organs) as they have been heretofore constructed, that they are clumsy and heavy to handle, and awkward and inelegant in appearance, owing to the size and inartistic proportions of the cases.

The object of my present invention is toobviate these objections, and to produce an :instrument which shall be symmetrical in its design, and, therefore, pleasing to the eye.

To this end the invention consists in adapting a case made in the form, proportion, and size of an upright-piano case for the reception of the working parts of an organ; by providing such case with an opening immediately below the key-board, to receive the hinged end ofthe exhaust-chamber of the bellows; by constructing an air-passage or air-trunk in or upon the rear wall of the case; and in certain other construction and adaptations ofthe working parts of the organ, which shall render it convenient to place it within a case of the desired form, as will be fully explained.

In the drawings, A represents the front of the case, A1 the end, A2 the top, and A3 the back. B B are the treadles connected with and operating the feeders of the bellows in any usual or approved manner. (l are the feeders, and O1 the exhaust-chamber. D is the wind-chamber, into which the air passes from the reeds, which are shown at d, D1 being the reed-board.

It will be observed that the board which forms the bottom of the wind-chest also constitutes the upper stationary part of the eX,- haust-chamber, and that by this construction I am enabled to reduce the thickness of that part which projects beyond the front A of the caseat the key-board. O2 is a spring used to distend or expand the exhaust-chamber. c is an inlet or air-passage from the wind-chest into the exhaust-chamber. c1 is an air-passage or throat formed in the bottom board' of the wind-chest opening into the exhaust-chamber, and leading to a similar throat, c2, in the back A3 of the case, or back board or stationary portion of the feeder or feeders C, this throat opening into this feeder, so that there is a continuous passage from the wind-chest D to the feeder O through the exhaust-chamber O1, broken only by the valve c3. c4 is a valve over the outlets c5 in the hinged board of the feeder.

As I am desirous of making the wind-chest D as thin as is practicable, for the sake ofthe appearance of that portion which projects in front of the part A of the case, I usually employ a cap, d', which is rabbeted or grooved upon the under side, to form a part of the throat ol but I may, under some circumstances, form the throat wholly in this bottom board or on the under side thereof, or I may attach back leather C3 of the exhaust-chamber to the back of the case A3, or of the feeder, and out a throat through this back board into the throat c2, although I prefer the construction shown. D2 are the keys, pivoted at their rear ends, and provided with steadypins d2 at their front ends, in any approved manner. E is a fulcrum-valve pivoted at 6 t0 the under side of the top board of the windchest, and covering the aperture through this board into the reed-cell. The front end of this fulcrum-valveis chamfered upon its upper surface, so that this end may be actuated by the lever E to open the valve, as will be readily understood. valve for each reed-cell, and a closing-spring, e2. Lever E is pivoted at el. e3 is a tracker-pin resting upon lever E', and depressing the front end of said lever whenever the corresponding key is pushed down.

In order to prevent the leakage of air into the wind-chamber around the pitmen, I em- Of course there must be a ploy a flexible packing-strip, F, arranged substantially as shown, either above or below the tracker-pins, and interposed between them and either the keys D? or the levers E', as the case may be, the edges of this strip being secured to the top of the wind-chamber or to a steadystrip thereon. I usually prefer to make this packing-strip of thin rubber, but may use any suitable material, care being taken to furnish sufficient slack to allow each pitman to be depressed the requisite distance Without displacing any other pitman.

I claiml. A reed-organ bellows, having a vertical feeder hinged at the lower end, and an eX- haust-chamber arranged at right angles thereto, and hinged at the front, substantially as set forth.

2. A wind-chest, the bottom of which is provided with an air-passage leading to the exhaustchamber, and also with a throat leading to an air-passage in the back of the feeder or feeders, substantially as set forth.

3. The flexible packing-strip F, in combination with the tracker-pins e3, and the windchest D, substantially as set forth.

4. The combination of the iiexible packingstrip E, the tracker-pins e3, the lever E and fulcrum-valves E, with the wind-chest D, substantially as set forth.

5. The herein-described organ-case, provided withl an opening below the key-board to receive the exhaust-chamber of the bellows, substantially as set forth.

6. The herein-described organ-case, consisting of the narrow upright part, and the projecting key-board, having the opening below the same, in combination with the bellows made in two parts, arranged at right angles to each other, the vertical portion being arranged within the case, and the horizontal portion projecting beneath the key-board, substantially as set forth.

In testimony that I claim the foregoing as my own I have affixed my signature in presence of two witnesses.

H. N. GOODMAN.
