REED-ORGAN.

SPECIFICATION forming part of Letters Patent No. 363,387, dated May 24, 1887. Application died February 11l 1887. Serial No. 227,332. (No model.)

To aZZ whom it may concern:

Be it known that I, .IAMEs BAILLIE HAMIL- TON, a subject of the Queen of Great Britain, though residing in the city and county of Worcester, of the Commonwealth of Massachusetts, have invented a new and useful Improvement in Reed-Organs; and I do hereby declare the same to be described in the following specication and represented in the accompanying drawings, of which* Figure l is a front elevation, and Fig. 2 a vertical and median section, of two duplex 4reed-cells of a reed-organ with my invention applied to them, the nature of the said invention being defined in the claims hereinafter presented. Fig. 3 is a top view of the valve C and its kneelever,showing the projection extending from the lower arm of the said lever, of which leversuch valve may be considered as a part. Fig. 4 is a front View, and Fig. 5 a side view, of a valve, its operative spring, and actuating Wire or bar; and Fig. 6 is a vertical section of such valve and its reedcell and the reeds thereof-the reed cell in such lastmentioned ligure being without the bridges and the reeds being without the gates, as hereinafter described-such ligure being to show how the valve and its operative lnechanism, as hereinafter explained, may be used with an ordinary duplex reed-cell and its reeds arranged wholly within it.

In Figs. l and 2 of such drawings, A and A are two reed-cells or induction airApassages, in each of which are two reeds, B, .inclined relatively to each other as represented. To the mouth of each of the saidV cells there is a valve or pallet, C, which, when closed, bears near its upper and lower ends against two bridges, a, extending horizontally across the cell-mouth.

The spring for closing the valve is shown at s as furcated or having two branches, to straddie the lower part of the valve kneelever and bear against a pin, t, that goes through the said valve knee'lever transversely. Thespring serves to return the valve to its seat, and on the valve being turned down such spring will give Way and allow of such, and will hold the valve in position when so turned down.

Each of the reeds shown in Fig. 2 is provided with a flange or gate, b, that extends across it', and, when the reed is in place in its cell, bears against the front side of the next adjacent bridge, and serves to close the port or opening that there is between the reed and the next adjacent bridge, to enable the reed to be inserted into its socket or withdrawn therefrom without obstruction from the reed-tongue or its fastenings. In front of the said gate b there is in the reed a nick, c, to receive the end of a hook when used to extract the reed from its socket.

The valve C is attached to the upper arm of a knee-lever, D, whose fulcrum is at f, the lower arm of such lever having extending from lit laterally a projection, t', to extend under a stud or button, h, on the actuating rod or bar g, leading to the key for operating the valve, the whole being arranged so as to admit of the valve being turned down into a horizontal position, as shown. in dotted lines in Fig. 2, aside of and without obstruction from the rod or bar g, one object of so turning down the valve being to enable access to be had to the interior of the reed-cell, as occasion may require, for cleaning it of dust or otherwise.

There is through the upper arm of the valve shown in Fig. 2 an opening or passage, 7a, into which the lower reed projects more or less when the valve is closed, such opening being to allow of the introduction of the reed into its socket in the cell, or its extraction therefrom, through the valve-lever D, without the necessity ot' requiring the valve to be first moved off its seat.

In Figs. t and 5 the valve is shown at C, its knee-lever at D, and the projection of the latter at z' to extend under the button or projection 7L from the actuating wi re or bar g.

In Fig. 6 the reed-cell is shown at A as pro vided with the two reeds B, the mouth ofthe cell and the fr'ont ends of the reeds being covered by the valve when closed.

Vith my improvement the valves of a series of reed-cells arranged in line, one over another, may be operated by a single wire or bar, g, suitably applied to a key.

To the. opening o, leading from each induction-chamber A into :its educt-ion-chamber F, there is a sliding register or valve, E, for closing such opening. In practice this slide is in one long piece of material, having openings through it to correspond with those ofthe horizontal range of induction and eductiou cham- IOO bers. On drawing the slide lengthwise in one direction all the said openings of the said chambers may be at once closed, and by running the slide the opposite way all may be opened. The object of this slide is to prevent sounding the reed, as occasion may require, when the valve thereof is open. The cell for this valve I form by a saw-kerf, l, of a depth to correspond with the thickness of the slide, and of a width greater than that of the slide, such kerf extending inwardly from the front m of the bar or block in which the reeds are arranged. Into the anterior part of the kerf there is inserted a narrow strip, n, of. wood, covered on its opposite sides with cloth or other suitable material, it being held in place by screws extending from the upper edges of the reed-cells up through such strip and into the wood or material above it, one of such screws being in each or every other reed-cell and over its reed. By means of the screws the joint between the strip and upper and lower edges of the said kerf can be iirml y closed, as occasion may require.

`1 claim- 1. The eombiuation,withfthe valve C, its op erative lever B, and actuating-wire y, arranged as represented-wiz., so that the valve while being turned down shall not be obstructed by the said wire-of the button h,`aixed to the wire, and of the projection extending from the lower arm of the said valve-lever underneath the said button, all being substantially as described, in order to admit the valve on ,being turned down of being moved out of, and on being turned up of being put into, engagement with the said wire, as explained.

2. The reed provided with the gate extending from it, as represented, to aid in closing thereed-entrance port of the reed receiving socket.

3. The reed air-induction passage or cell, provided with the reed-entrance port, and the bridge or bearing a for the reed gate and valve to rest against, such bearing being at one end of such pass-ige, and all being substantially as represented.

4. The combination of the reed-induction passage or cell and the two reeds arranged in its upper and lower parts and having gates to them, as set forth, with a single valve applied to such passage at one end thereof, and with bridges or bearings for the gates and the valve near its upper and lower ends to rest against.

5. The slide-0rentoff cell, formed asdeseribed, and provided with the closing-stri p n, fastened in place by screws arranged in the front of the reed-cells.

6. The combination of the valve, and an arm or knee-lever projecting therefrom, with the aetuatingspring of the latter, and with the valve-operative rod or bar provided with the button or shoulder, arranged so as to admit of said valve and arm or knee-lever being turned down in a manner to carry the latter out of engagement with the rod 0r bar and the valve down to or nearly to ahorizontal position, and to cause said valve to be supported or held therein by the spring, such spring, on the valve being raised to its seat, serving to press it closely thereon.
