SPECIFICATION forming part of Letters Patent NO. 784,203, dated March "K, 1905.

Application filed January 23, 1903. Serial No. 140,286.

Be it known that I, JACOB BTNNIG, a citizen oi' the United States, residing at Boston, county of Suffolk, State oi' Massachusetts, have invented an Improvement in Organs, of which the following description, in connection with the accompanying' d rawings, is a speciiication, like numerals on the drawings representing' like parts.

I O This invention relates to organs,`and has especial reference to thevalve which controls the communication between the register windchest and the sound-producing device or devices; and the object is to secure a valve which I5 will be simple and inexpensive to manufacture and which will operate to admit the air to the sound-producing device with the freedom necessary to make the instrument most eii'ective.

In the embodiment of my invention which 2O I have herein illustrated the valve comprises a iiexible diaphragm which extends across the usual valvechamber, which is located between the usual register wind-chest and the sound-producing device, and said diaphragm coacts with a Valve-seat which is made by an annular lip or 'liange which surrounds the port leading' from the wind-chest into the valvechamber and which extends into the valvechamber. The result is a valve in which the valve-seat is situated some distance trom the sideotl the val ve-chamber. Iith this construction whenever the valve, whether it be in the nature of a diaphragm or ot' any other construction, is raised from its seat the air is permitted to flow freely from the wind-chest to the sound-producing device.

l In the drawings, Figure l is a vertical sectional view throug'h certain parts of the organ, showing my improved construction; and

40 Fig. 2 is an enlarged partial section on substantially the line w af, Fig. l.

3 designates the usual register wind-chest, which may be of any usual or suitable construction and which will either be connected to a force-bellows or a suction-bellows, ac-

cording to the particular type of organ in which my improvements are used.

4L indicates a sound-producing device, which may be oi' any suitable or usual construction, though that herein illustrated is in the nature of one of the pipes of a pipe-organ. This invention, however, can be used in connection with other sound-producing devices without changing' its mode oi' operation.

Between the sound-producing device and register wind-chest is the usual valve-chamber 5, in which is situated the valve 'lor controlling the communication between said parts, it being understood that the valvechamber is connected to the sound-producing device by a port 6 and also with the windchest by a port 7. ticularly to the construction of the valve, which will now be described.

Extending across the valve-chamber and. dividing it into compartments S and 9 is a ilexible .diapln'agm I() of some suitable materialsuch as sheepskin, leather, dce. This diaphragm coaets with a valve-seat Il, shown in this embodiment ot' my invention as in the form of an annular lip or ilange l2, which surrounds the port 7 and projects from the wall of the valve-chamber and into the latter. This lip or flange may either be integral with the Vabre-chamber wall or may be Aformed by the projecting end ol a bushing 1?), which is litted to said port, The compartment S ot' the valve-chamber communicates through a suitable port or duct 14 either with the atmosphere or with an action \\'indchamber, as determined by any usual valve, one liorm of which will be presently described. The airpressurc in the register wilul-cluunher i3 is normally slightly less than that in the action wind-chamber I9, and under normal comlitions the compartment S ot' the valve-chainber will have commuilication with the action windchamber. Under these conditions the valve I() will be held to its seat, as shown at the left` Fig. l, and coi'nmunication between the register wind-chamber and the sound-producing' device will be closed. When, however, the key oi' the organ corresponding to the sound-producing device 4@ is operated, the compartment S otl the valve-chamber will be open to the atmosphere and the pressure therey invention relates parin relieved. As a consequence the greater pressure in the wind-chest 3 will lift the valve from its seat, as shown at the right, Fig. 1, thus allowingair to pass from the wind-chamber 3 to the sound-producing device. Since the valve is situated some distance from that wall of the valve-chamber which is adjacent the wind-chest 3, the air can flow Jfreely over the valve-seat 11 into the compartment 9 of said valve-chamber and thence to the soundproducing device.

T he mechanism for controlling' the air-pressure in the compartment 8 may be of any suitable or usual type. As herein illustrated the duct 14 opens into a chamber 15, having a port 16 leading to the atmosphere and a port 17 leading into active wind-chamber 19, which is connected with the bellows by a pipe 2O and which contains the pneumatic 18 for operating' the valves 21 and 22, which control the ports 16 and 17, respectively. rlhe pneumatic is connected by a suitable pipe Q3 and port 24 with an action wind-chamber 25, which will be connected to a suitable force-bellows. A spring-pressed valve 28 normally covers the port 24, and said valve is connected, through suitable lever mechanism 29, to one ot' the o1'- dinary manual-keys 30. With this construction it will be observed that whenever the key 3() is depressed the valve 28 will be opened and air-pressure admitted to the pneumatic or motor 18 from the chamber 25. rlhe eX- panding of the pneumatic will raise the valves 21 22, thus closing the port 17 and opening the port 16, as indicated at the right, Fig. 1. This places the compartment 8 ol the valvechamber in communication with the atmosphere and relieves the pressure therein, lthus allowing the valve 10 to open, as above described.

In construct-ing the organ there will be a valve-chamber 5 for each pipe of each register or series of pipes, and preferably these valve-chambers will be formed in a plank or board 30, which extends across the front o'f the organ, said plank or board having in its upper edge the ports 6, to which the soundproducing devices or pipes are connected. in most pipe-organs a plurality of series or registers of pipes are employed, and when such is the case l will preferably arrange the valve-chambers as shown in Fig. lthat is, the valve-chambers for two adjacent series ot' pipes will be placed back to back and the compartments 8 of the opposing chambers of the two series will open into the same duct 14. It is necessary, however, in this case to employ a separate register wind-chest 3 for the second series of soundproducing devices 4.

4n and 4" designate two other series or registers ol sound-producing devices, and 3 and 3 are the corresliionding register wind-chests.

lThe valve and valve-chamber between each of these wind-chests and the corresponding sound-producing1 device have the same construction as that already described, and the valvemechanism for controlling the air-pressure in the compartments 8 is similar to that already described.

The novel feature of this invention resides in a construction in which the valve-seat is situated between the opposite walls olI the valve-chamber, so that when the valve is raised from its seat the air can v(low through the valve-chamber with the greatest possible freedom. Vlt will be obvious. therefore, that many changes may be made in the construction herein shown without departing from the invention.
