Description
July 25, 1939. D. MARR MAGNET FOR ORGANS Filed Fb. 17, 1939 flew dd Mar-r ATTORNEYS Patented July 25, 1939 UNITED STATES PATENT OFFICE 5 Claims.
This invention relates to magnets for organs and has for an object to provide a simplified magnetic valve for use as a pipe valve and for other purposes in organs.
A further object is to provide a device of this character which may be easily applied and removed without the use of screws or other connectors and in which a solenoid and valve are housed in a single casing to the end that the device will be compact and take up little room in the organ mechanism.
A further object is to provide valves of this character which may be readily mounted on a single pine board, forming part of the organ chest, and which provides a sound board to promote resonance to the sound or vibrations of the pipes, similar to the sounding board of a piano.
With the above and other objects in View the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claims without departing from the spirit or sacrificing any. of the advantages of the invention.
In the accompanying drawing forming part of this specification:
Figure 1 is a cross sectional view of a portion of a pipe organ wind chest and pipe and showing applied thereto a magnet valve constructed in accordance with the invention.
Figure 2 is a longitudinal sectional view of the magnet valve shown in Figure 1.
Figure 3 is a cross sectional view taken on the line 3--3 of Figure 1.
Figure 4 is a side elevation, with portions broken away, of a modified form of the magnet valve in applied position.
Referring now to the drawing in which like characters of reference designate similar parts in the various views, [0 designates a wind chest for holding a series of valve actions adapted to control the flow of air to the pipes H of an organ. These pipes are mounted at their lower ends on the wind chest and are provided with ports I 2 for conducting air to the pipes.
In one embodiment of the invention a counterbore I3 is formed in the wind chest to receive the casing 14 of the magnet valve, the casing being open at the top and communicating with an opening 15 which supplies air from the wind chest to the respective pipe through the port l2.
The casing is preferably in the form of a tube of insulating material having frictional engagement with the wall of the counterbore I3 so that it may be quickly removed or applied without the use of tools. A solenoid I6 is mounted in the end portion of the tube and is provided with an armature I! which extends substantially through 5 the tube when retracted by energizing of the solenoid. An organ valve I8 is mounted on the end of the armature and seats on the end wall of the counterbore to control admission of air to the pipe through the opening I5. The casing I3 10 is provided with a transversely disposed port [9 through which air enters the casing from the wind chest for admission to the respective pipe H. The armature is provided with a laterally extending pin 20 which projects through a longi- 15 tudinally extending slot 2| formed in the casing.
A felt or other cushion 22 is disposed on the end of the solenoid to cushion the pin against shock and limit opening movement of the valve when the armature is withdrawn due to energizing of 20 the solenoid.
A coil spring 23 is provided with two legs 24 and 25 which extend parallel to each other. The leg 24 is provided with an angularly bent extremity 26 which is wedged into the counterbore 25 [8 between the casing and the wall of the counterbore so that the spring is normally held against dislodgement but may be removed as a unit with the magnet valve when inspection or repairs is necessary. The free leg 25 of the 30 spring is engaged underneath the pin 20 and normally holds the valve l8 seated. When the solenoid is energized the spring is deformed and stores up energy to quickly close the valve immediately the solenoid becomes de-energized. 35
The ends of the solenoid coil are carried outside of the casing and connected to terminals 25' to which conductor wires 21 may be secured in the usual manner.
The magnet valve above described and illus- .40 trated in Figures 1, 2 and 3 is preferably used in connection with small pipes. In the modified form of magnet valve shown in Figure 4 the valve may be used in connection with large pipes as will now be described. 45
In the modified form of the invention the parts are the same as previously described with the exception that the armature 28 is equipped with a pair of valves 29 and 30. This modified form of the invention may be used in connection 50 with a wind chest 3! having a bellows 32 coacting with a spring 33 for holding the valve 34 seated. The bellows is supplied with pressure from the wind chest through a duct 35 which communicates V with a port 36 formed in the bottom wall of the wind chest and communicating at the top with the interior of the wind chest and communicating at the bottom with the open upper end of the solenoid casing 31, which in this instance, is inserted at the upper end in a counterbore 38 forming a continuation of the port 36.
The lower valve 30 normally seals the bottom of the port 36 while the upper valve 39 is in open position to permit air pressure to enter the bellows from the interior of the wind chest. When the solenoid 39 is energized the armature 28 is retracted against the pressure of the coil spring 40 to open the lower valve and close the upper valve.
Thereupon the air pressure in the bellows vents to the atmosphere through the duct "35,.port'36, casing 31 and opening 4| in the side of the casing. The excess pressure in the wind chest acting against the atmospheric pressure in the bellows collapses the bellows which through the medium of the conventional link 42 immediately pulls open the valve34 and supplies the pipe 4-3 with wind chest pressure. Upon the solenoid becoming deenergized the position of the valves is reversed cutting oii communication between the bellows and the atmosphere and establishing communication between the bellows and the interior so that the bellows is extended and closes the valve 34.
It will be pointedout, and the scope of the invention extends to, the feature that these valves are=easi1y mounted on the organ chest. Also that all of the valves may be assembled on a single pine board, such as the top E3 of the chest, which board then provides a sound board that promotes resonance of the sound or vibrations of the pipes of the organ, similar to the sounding board of a piano.
From the above description it is thought that the construction and operation of the invention will be fully understood without further explanation.
