Application. filed September 29, 1914.

To @ZZ 'whom t may concer/c Be it known that l, Pitney Prnsron, a citizen of the United States, residing at Denison, in the county oll Grayson and State oi rferias, have invented a new and useful Reed-Organ, ot which the following is a specification.

This invention relates to reed organs and more particularly to reed boards for use in connection therewith.

ne object of the invention is to provide means whereby dust is prevented from lodging in the reeds.

further object is to provide an iinproved construction of reed board having the reeds and pipe cells connected in anovel manner.

lWith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the coinbination and arrangeinent of parts and in the details et construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be inade within the scope of what is claimed, without departing` troni the spirit of the invention.

in the accompanying drawings the preferred torni of the invention has been shown.

ln said drawings z-Figure l is a longitudinal section elevation ot a reed board enibodying the present improvements said section being taken ou line lli-l, Fig. the valves being shown closed. vi`ig. 2 is a section on line C-D Fig. l. Fig. 3 is a section on line E-F Fig. l. l is an enlarged transverse section through the reed board and showing the connec ion between the key and the valve, the valve being shown in its open position.

Referring to the Jfigures by characters ot reference l designates reed cells which can be ot the saine width or, it preferred, oi' different widths. rlhe front and rear faces of the reed board converge gradually toward the treble end and, consequently, the reed cells formed in the board gradually increase in depth toward the bass end of the register. Reeds niay be supported within the cells in any manner desired. ln the structure illustra-ted, the reed blocks protrude slight distances from the cells at the treble end of the board but this protrusion gradually lessens toward the center of the board after which the reed blocks are contained wholly in the Specification of Letters Eatent.

cells, as shown in Fig. B, the corresponding ends of the reed blocks being disposed along a straight line. rihe reeds have been illustrated at 2 and the reed blocks at 2.

Below the reed cells l are arranged pipe cells fl forming resonance chambers or cells which, as shown in Fig. l, gradually increase in height troni the treble toward the bass end or the register. rjliese resonance chainbers are separated troni the reed cells by horizontal partitions i. These partitions are provided at their trent ends with openings .3 affording tree communication between the iront ends oi the reed and pipe cells. is shown partcularlj.Y in Fig. 2, these openings gradually increase in size troni the treble toward the bass end oi: the register.

rI'he resonance cells 3 are separated troni each other by vertical partitions G which are in vertical alineinent with or 'forni continuations ot the corresponding vertical partitions located between the reed cells l.

In the construction illustrated, every other one ot the partitions t3 extended down to the bottoni ot the resonance chamber while the remaining partitions G are cut away at the bottoni to torni spaces shown at Y whereb v the resonance cells are divided into groups ot two each, the cells ot each group connnunicatinf'g. is the partitions between the groups ot resonance cells extend cornpletelv to the bottoni, a consi( erable volume oit air is inclosed which will be set into vibration when the reed is sounded.

The. size of the spaces 7 Jfoi-ined below certain ot the partitions 5 depends on the positions of the cells in the register.

it will be noted by referring particularly to el. that the reeds which are within the upper portions of t ie reed cells l will not accumulate dust.

The valve for use in connection with the reed has been indicated at S, and includes a flexible strip 8 constituting a hinge. The valve is connected b v a tracker 9 to the key lever lO. A spring li is arranged above the valve. Pins 12 can be arranged in the upper portion ot the reed board to guide the valves.

Vilhat is claimed ist l. In a. reed board, resonance cells, reed cellsy arranged thereabove and separated therefrom by partitions, there beinO' openings within said partitions tor maintaining communication between the reed cells and the resonance cells, and reeds attached to the tops of the reed cells, said resonance cells being grouped, the cells of each group communicating through openings adjacent the bottoms of the resonance cells.

In a reed organ, a reed board having resonance cells, reed cells arranged thereabove and separated therefrom by partitions, there being openings within said partitiens for maintaining communication between the reed cells and the resonancevcells, reeds attached to the tops of the reed cells, said resonance-cells being grouped, the cells of each group communicating through openings adjacent the bot-tenis of the resonance cells, a valve above each reed, a key lever, a tracker interposed between the key lever and its valve,Y and a spring bearing upon the valve for directing it to its seat.

3. in a reed board, resonance cells, reed cells arranged thereabovev and separated as my oivn, I have hereto aiiixed my sig nature in the presence of tivo Witnesses.
