Letters Patent No. 107,755, dated September 27, i870.

IMPROVEMENT IN REED-BOARDS FOR ORGANS.

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

To whomib may concern Be it known that I, RILEY BUnDn'r'r, of Chicago, in Athe county of Cook, State of Illinois, have invented a new and useful Improvement in Reed-Organs; and the following is a full and accurate description thereof, reference being had to the accompanying drawing and the lett-ers of reference thereon- Figure l being a perspective, and' .Figure 2, a plan view of my reed-board.

This invention relates to the construction of a celestc organ with a Manual sub-bass, in such a manner as to simplify thc instrument, reduce the cost, and yet preserve thc much-:ulmired tone which distinguishes thc larger .and more expensive. organ of this kind.

It is constructed similar' to other reed instruments as respects thc ease, suction-bellows, keys, trackers, valves, and wind-chest; but thc arrangement of the reeds and recd-board is altogether different. This is shown in the drawingprhere the relative positions of the reeds are-exhibited.

A is a unison set of reeds, extending through the scale or compass of the organ.

B is the celeste set of reeds.

C shows the. sub-bass reeds, all of which are affixed to the plate E, or, if desired, they may be attached to separate plates.

'.lhe most desirable compa-ss for the organ is iive octavos, commencing on F Ii in the bass, and ext-endin;` up to l alt. rIhe celeste set of reeds commences 'on tenor F, or thercabout, and runs up thrcc octavos. The sub-bass may commence on C C, but must bc sutliciently large and heavy to be tuned one octave below the unison set and secure a powerful tone.

All of the reeds, excepting the sub-bass, are inserted in separate cells in thc reed-board, in the usual manner; but the construction ofthe reed-hoard for the sub-bass differs altogether', there being only one cell or chamber for all the reeds which consist of one octave, or thcreabont.

This is an important improvement, as thereby the whole space occupied by all therecds is a reverberating chamber for each reed, thus seeming a degree of power, and also an improvement in the quality of the tone not attainable when each reed is a separate cell or chamber, as heretofore constructed.

I) shows the hole through the reed-board for the trackers, which communicate to the. valves from the keys, all of which are made quite similar to those in general use.

Another feature wherein the sub-bass dii'ers from all others is, that no additional valves are needed, as the same valves which admit the passage of the air for the unison reed also admit it for the corresponding` sub-bass reed.

The celeste set of reeds is tuned a little sharp or flat of the unison set, but' only sufficiently so as to produce that agreeable waving, undulating quality of tone so pleasing` and desirable.

Stop-dampers, constructed in the usual manner, are aftixed to the sub-bass and celeste set, so that diiercnt combinations ot' tone may be produced at the pleasure of the performer.

\Vhat I claim as my invention, and desire Letters Patent therefor, is as follows:

li The arrangement, in a single reed-board, of the principal set A, the celeste set B, and the sub-bass set C, substantially as described. v

2. The arrangement of the snbr-bass setC in the principal reed-board, so that the air-passages of both may be controlled by a single set of valves.

3. The reeds of the sub-bass set- C, all located within a single cell in the reed-board, substantially as and for the purpose set forth.
