IMPROVEMENT 1N REED-oReANs.

Specification forming part of Letters Patent No. lS6,S45, dated January 30, 1877; `appli cation filed June 16, 1876.

To all whom t may concern:

' Be it known that I, GEORGE B. KELLY, of Boston, county of Sulolk and State of Massachusetts, have invented certain new and useful Improvements in Reed-Organs, of which the following is a specification This invention relates to that class of reedorgans in which an additional register is employed, in combination with an ordinary register, for the set of reeds; and it consists, first, in the combination, with the ordinary stop of a set of reeds, of an additional stop, located within a chamber on the board in which the reeds are located, and through which work the stems for opening the valves to each reed, by means of which less air can be made to pass to the reeds, when desired; second, in a valve arranged to open inwardly to the said chamber in which the additional register is located, in combination with the ordinary reed register or stop, as more fully hereinafter set forth.

In the accompanying plate ot' drawings, Figure l 1s a plan view of my improved combination ot' registers; Fig. 2, a section along' line m x, Figs. 1 and 3; Fig. 3, a cross-section on line y y, Fig. 2; and Fig. 4, a view of one end.

In the drawings, A represents a board, in which are arranged four sets of reeds, B1 B2 B3 B4, each set having a register, Ol O2 C3 O4, all ot' which are adapted to be opened and closed, and the whole being constructed and arranged as ordinarily in reed-organs, therefore needs no more particular description herein. D D2, two registers, one to the set of reeds B1 and the other to the set ot' reeds B3, both of which registers are in addition to the usual registers O1 and O3 for each of said sets of reeds. These additional registers D D2 are arranged to open and close air passages or cells c to the reeds ot' the sets of reeds to which they are adapted, and they are also arranged to be operated, as is common for all registers in reed-organs.

In the use ot' my combination of two registers for a set of reeds upon the reeds of the organ from which the bassnotes are producedl arrange the said extra register, so that the air which can pass to the reeds when it is opened will be less in quantity than that which passes when the ordinary and common register for such reeds is opened, and thus softer base-tones will be produced; and, again, it' the two registers be opened at one and the same time, stronger and rounder basstones will be obtained.

The arrangement of the eXtra register to the bass-reeds for the purpose above stated is lwithin the chamber E of the board in which the reeds are located, and through which work the stems for opening the valves to each reed when the keys are played upon, and under such au arrangement less air can passto the reeds when that register is opened than when the ordinary register is opened.

F, a valve opening inwardly to the chamber E, in which the additional register D is arranged, as above described. This valve opens against a weighted spring-lever, b, which is hung to it and fastened to the outside of the cap-board H. Should the supply of air when the register D is opened be too weak, this valve opens, letting' in an additional quantity, and, obviously, by vhaving the weight c adjustable on the spring-lever b, the opening ot' the valve can be regulated as desired.

In combining the two registers with the reeds used for a celeste-stop, it is arranged and applied to only one ot' the two sets, and when so applied it gives an eXtra supply of air to such reeds, it' it be opened at the same time as the ordinary register thereof, whereby the celestetones are produced with the two sets of reeds tuned in unison, whereas, heretofore it was usual to tune them out ot' unison.

Again, with the additional register for one set of these -reeds closed and the two registers for the two sets opened, as the two sets are tuned in unison, an increased volume of tone can be obtained.

The chamber or space E above the reedcells, into which the reed-cells open when the eXtra register there located is opened, as described, gives a resonancy to and qualities the tones produced from the reeds.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

nl. The combination, with the ordinaryfstep' dnary reed register or stop, all arranged to f a set of reeds, of an additional stop, D,=1o operate substantially as herein shown and decated within theehamber E,vs'ubstantially as scribed.
