PNEUMATIC-VALVE FOR ORGANS.

SPECIFICATION forming part of Letters Patent No. 760,114, dated May 17, 1904.

Application filed August 21, 1903.

To all whom, it may concern:

Be it known that I, WILLIAM E. HASKELL, a citizen of .the United States, residing at Brattleboro, in the State of Vermont, have invented certain new and useful Improvements in Pneu- Inatic-Valves for Organs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of the present invention is to provide a pneumatic-valve for pipe or reed organs of improved and simplified construction which is quick and certain in its action and which can be used in various places in an organ to govern the ports of the air-channels and by the use of which the general construction, arrangement, and mode of operation of the various parts of an organ may be simplified and improved.

With this object in view my invention consists in the improved pneumatic-valve hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art from the following description.

My invention will be clearly understood from'an inspection of the drawings accompanying this application, in which-- Figure 1 is a sectional view illustrating somewhat diagrammatically a portion of an organ provided with pneumatic-valves embodying my invention in its preferred form. Fig. 2 is a plan view of one of said valves. Fig. 3 is a view in side elevation thereof. Fig. 4 is a longitudinal section thereof, taken on the line 4 4 of Fig. 2; and Fig. 5 is a crosssectional view taken on the line 5 5 of Fig. 4. Referring to Figs. 2, 3, 4, and 5, the valve illustrated comprises a base portion 1, a stationary board 2, extending from the base por-- tion and conveniently formed integral therewith by sawing the two parts from a single block of wood, a movable board 3, and a flexible sheet 4 of leather or other suitable material, forming the sides and one end of the internal chamber 5 of the valve. The base 1 forms the other end of the chamber 5 and is provided with a channel 6, opening at one end Serial No. 170,304. (No model.)

into the chamber and at the other'end upon the surface 7 of the base. The base 1 is adapted to be secured to the wall of a chamber or chest of an organ with the surface 7 in contact with the wall, so that the stationary board 2 extends from the base parallel with the wall to which the base is secured, and the movable board 3 is located between the stationary board and the wall. Upon the outer surface of the movable board 3 a valve-pad 8 is secured, which is adapted to govern a port opening into the chamber in which the pneumatic-valve is placed. The movable board 3 is pivotally mounted at one end upon the base 1, the end of the board being reduced in thickness and resting upon a shouldered seat a upon the base. A hinge 9, of leather or other suitable flexible material, forms an air-tight joint between the movable board and the base. The flexible sheet 4, which forms the sides and one end of the chamber 5 of the valve, is secured to the sides of the base and to the edges of the stationary and movable boards and is folded over upon the reduced end portion of the movable board, as is indicated at b b in Figs. 2 and 3. In order to avoid any possibility of the board 3 striking against the board 2 and producing a sound when the valve is collapsed, a bufferpad 10 is secured upon the inner surface of the board 2 beneath the outer end of the board 3. A spring tending to distend the valve is arranged to act upon the movable board 3. This spring is indicated at 11 and consists of a wire bent in the shape indicated in Fig. 4, one end of which bears against the inner surface of the movable board 3, being received in a groove therein, whereby the end of the spring is prevented'i'from being displaced, and the other end of which passes through the base 1 and is secured in position by means of a small nail ortack12. The spring 11 not only acts to distend the valve when the pressures within and without the valve are equal, but also acts to hold the valve distended against any back pressure acting on the valve-pad 8.

i The operation of the valve illustrated in Figs. 2, 3, 4, and 5 and above specifically described will be understood from an inspection of Fig. 1. In this figure, 13 and 14 indicate channels of the great and swell organ, respectively, which lead to the devices which control the admission of air to the pipes or reeds. 15 and 16 indicate two pneumatics, located, respectively, in constant pressure chambers 17 and 18 and arranged to actuate the double valves, 19 and 20 of the channels 13 and 14. A channel 21, provided with a permanent vent 22, connects with the pneumatic 15 and leads to a constant-pressure chamber 23. A similar channel 24, provided with a permanent vent 25, connects with pneumatic'16 and leads to the constant-pressure chamber 18. The ports of channels 21 and 24, opening into the chambers 23 and 18, are governed by pneumatic-valves 26 and 27, similar in construction to the valve illustrated in Figs. 2, 3, 4, and 5, hereinbe't'ore specifically described. These valves are located in the chambers 23 and 18 and communicate through their channels 6 with key-controlled channels 28 and 29. The pressure of the air in the channel 28 is controlled from the key 30 of the great organ through spring-pressed valvelevers 31 and 32, which govern ports in the channel opening into the atmosphere and into the key-chest 33 of the great organ. The pressure of the air in the channel 29 is controlled in a similar manner from the key 34 of the swell-organ through spring-pressed valve-levers 35 and 36, governing ports in the channel 29, opening into the atmosphere and into the key-chest 37 of the swell-organ. \Vhcn a key of the great organ is depressed, it being understood that the chambers 17, 23, and 18 and the key- chests 33 and 37 are supplied with air under pressure, the channel 28 is placed in communication with the atmosphere and the valve 26 is collapsed by the pressure of the air in chamber 23. The port of channel 21, opening into chamber 23, is thus opened and air under pressure is admitted to the channel, thereby equalizing the pressure within and without the pneumatic 15, the bottom board of which drops and actuates the valve 19 of the channel 13. When the key of the great organ is released, air under pressure is admitted to the channel 28, thereby equalizing the pressure within the valve 26 and chamber 23 and allowing the valve to be instantly distended by its spring to close the port of channel 21. The port of channel 21 being closed, the air under pressure in the channel escapes through the vent 22 and the pressure of the air in the chamber 17 raises the bottom board of pneumatic 15 to return the valve 19 to its original position. In the same manner when a key of the swell-organ is depressed the channel 29 is placed in communication with the atmosphere. the valve 27 is collapsed by the pressure in the chamber 18, and air is admitted from the chamber into the channel 24, thereby allowing the bottom board of pneumatic 16 to drop and actuate the valve 20 of channel 14. IV hen the key is released, the pressure within the valve 27 and the chamber 18 is again equalized, the valve is distended by its spring to close the port of channel 24, and the pneumatic 16 is actuated to return the valve 20 to its original position, the air in the channel 24 escaping through the vent 25.

In the construction so far described it will be seen that my improved valve is utilized as a means for controlling the valve of a sounding-channel from its corresponding key-controlled channel. I have also illustrated in Fig. 1 an arrangement in which my improved valve is utilized as a coupler-valve, forming a part of a pneumatic-coupler, whereby the valves of both channels 13 and 14 may be actuated simultaneously upon a depression of the key 30 of the great organ, this pneumatic-coirpler forming the subject'matter 01 a separate application filed herewith, Serial No. 170,305. The valve which forms apart of the pneumaticcoupler referred to is indicated at 38 and is located in a stop-controlled chest The valve communicates through its channel with the key-controlled channel 28 and governs the port of a channel 40, opening into the chest 39 and leading to the channel 24. By this arrangement when the stop of chest 39 is drawn so as to admit air under pressure into the chest and the key 30 of the great organ is depressed the valve 26 is collapsed, so as to cause an actuation of the valve 19 of the channel 13, as hereinbefore described, and simultaneously the valve 38 is collapsed by the pressure in the chest 39 and air under pressure is admitted from the chest into the channel 24, thereby causing the valve 20 of channel 14 to be actuated simultaneously with the valve 19 of channel 13. In Fig. 1 I have also illustrated a second coupler-valve 41, located in a stop-controlled chest 42. This couplervalve communicates with the key-controlled channel 28 and governs the port of a channel 43, leading to another valve-actuating pneumatic (not shown) similar to the pneumatic 16. I have also illustrated in Fig. 1 a channel 44, similar to the channel 40, opening into the channel 24. The channel 44 leads to a port controlled by a pneumatic-coupler valve (not shown) connected to another key-controlled channel.

It is to be understood that my improved pneumatic-valve may be used in parts of the organ other than those illustrated in Fig. 1 of the drawings and that the figure merely illustrates one of many constructions and arrangements in which my improved valve may be used to advantage. It is also to be understood that except as defined in the claims my invention is not limited to the specific construction and arrangement of the various parts of the valve illustrated, but may be otherwise embodied without departure from the spirit thereof.

Having thus described my invention, I claim IIO as new and desire to secure by Letters Patent of the United States 1.
