UNITED STATES EDMOND VERLINDEN, OF MILWAUKEE, WISCONSIN.

ORGAN VALVE.

Application filed July 26,

The invention relates to organ valves, more particularly for use with treble chests. but capable of application to other organ chests.

An object of the invention is to provide an organ 'alve construction which will avoid improper actuation of air-pressure--operated devices incident to the leakage of air to the conduits leading to such devices.

Another object of the invention to provide an electro-magnetie organ valve which is prompt in action and is of simple, durable and inexpensive construction.

A further object of the invention is the provision of an electromagnetic organ valve which can be mounted and assemble-l in a simple manner and which is readily accessible for the purpose of wiring, inspection, repairs and replacements.

The invention further consists in the several features hereinafter set forth and more particularly defined by the annexed claims.

In the accompanying drawings:

Fig. 1 is a transverse sectional elevation through a. treble chest embodying the organ valve construction of this invention;

Fig. 2 is a fragmentary plan view thereof with the pipes removed, parts being broken away and parts being shown in section;

Fig. 3 is a bottom plan view of one of the valve casings; and

Fig. 4 is a fragmentary sectional elevation of a modified form of valve.

In these drawings, 10 designates a treble chest having a. longitudinally extending air channel 11 supplied with air under pressure. The chest includes an aperturcd member 12 disposed above the channel 11 and preferably provided with a facing 13 of leather or other suitable material on its upper surface. A pipe-sup )orting strip 14 is secured longitudinally along one edge of the member 12 and carries a series of organ pipes 15, each communicating with an upright passage 16 extending through the strip.

A series of upright air passages 17 extends through the member 12 in communication with the subjacent air channel 11, there being an air passage 17 for each pipe 15. Each air passage 17 closed atits upper end by a valve casing 18 secured to the upper face of the member 12 by screws 19. Each valve casing is provided with a recess 20 in its bottom face registering with the air passage 17 and including an enlarged portion 21 laterally offset with respect. to the. air passage 1926. Serial No. 124,978.

17 to confine therein for limited vertical nioven'ient a disk valve 22, which, in the present instance, includes magnetizable ma terial to form armature. In accordance with common practice the disk valve is faced with leather, paper or other suitable material to insure good seating and to avoid sticking and sluggish action. The valve casing 18 is attached permanently to an upright electro-magnet 23, the pole pieces .24: of which are embedded in the valve casing and have their lower ends projecting below the upper face of the recess or cavity 20, where they are preferably surrounded by bosses 25.

Each disk valve 2 is adapted to seat over one end of an air p: 26, the other end of which opens into a. recess 27 in the member 12 registering with the air passage 16 communicating with the pipe A venting port or passage 28 is also formed in the strip 14. in communication with the recess 27 and is preferably. though not necessarily. of somewhat larger cross-sectional area than that of the pipe 15. The venting passage 28 preferably includes laterally extending portion opening at the side edge of the strip 14 in order to avoid settling of foreign matter through the passage and into the recess 27.

Each recess 27 is preferably of the general key-hole shape seen in Fig. 2 in order to present confining walls for a horizontally disposed disk valve 29 which is mounted for limited vertical movement within the recess to close either the outer end. of the air passage 26, as seen in Fig. 1, or the inner end of the venting passage 28, as hereinafter de scribed. For this purpose, the adjacent ends of the passages 26 and 28 are in substantial alignment.

In the modified form of elcctro-magnetic valve shown in Fig. l the valve casing 18 encloses a recess 20' formed in the member 12 and in comnninication with the air passage 17. The recess 20 may be of the same general shape as that of the recess 27, in order to confine therein for liu'iitcd movement a disk valve 22, which also forms an armature co-operating with an electro magnet 23 having its pole pieces 21 embedded in the valve casing.

The disk *alves 22 normally est against their seats to close communication between the air passag les 17 containing air under pressure and the air passages 26 leading to the The seating of the valves is rendered firm by the pressure of the air above them. lVhen it is desired to have a pipe speak the corresponding electromagnet 23 is energized, thereby lifting the disk valve 22 and admitting air under pressure from the recess 20 into the passage 26. The disk valve 29 at the outer end of this passage will then be lifted by air pressure into seating engagement With the bottom face of the strip ll and closing the inner end of the venting passage 28, thereby permitting the flow of air under pressure into the recess 27, through the passage 16 and thence into the pipe, causing it to speak. Under such conditions the air pressure in the recess 27 will hold the disk valve 29 firmly against'its upper seat to close the venting passage 28, so that the full air pressure supplied available for the pipe. As soon as the magnet 23 is deenergized the disk valve 22 will drop to close the air passage 26 with respect to the recess 20, and the disk valve 29 will drop immediately thereafter to open the venting passage 28 with respect to the recess 27.

In order to insure the prompt dropping of the disk valve 22 from its upper position when the magnet 23 is (lo-energized, a sul stantial area of the upper surface of the valve is also subject to air pressure by reason of the pole pieces 24- and bosses 25 pro jecting below the upper surface of the recess 20, thus largely counteract-ing the pressure of air on the bottom surface of the valve when the valve is unseated.

In the case of the smaller organ pipes it will be appreciated that air under relatively low pressure is sufficient to cause them to speak and that ciphering can be easily caused by small particles of sawdust or other foreign matter obstructing the complete closing of the valves. This condition has heretofore necessitated the inconvenience of adjusting or dismantling in order to re store normal operation. In the organ valve construction of the present invention the possibility of ciphering is obviated by providing the venting passage 28, which is preferably of substantially larger area than that of the organ pipe, so that any leakage into the passage 26 will pass the disk valve 29 by lifting it slightly and be dissipated through the venting passage, thus preventing the accumulation of suflicient pressure to sound the pipe. Under the application of'the lowest normal air pressureto, the passage 26 the disk valve 29 will close the venting passage 28 to permit functioning of the pipe in the normal manner. By seating the valve 29 over the outlet end of the passage 26, the lifting of the valve to close the venting passage will be facilitated and insured.

It will be seen that the venting means is operated directly by the air blast to the pipe and does not require a rnecnanical actuating connection with a valve membrane or pneumatic. This greatly simplifies construction and design, facilitates assembly and lessens cost of manufacture. The venting mean insures a prompt cessation of the speaking of the pipes and permits good staccato playing. Vlhile the venting means 7 s more particularly intended for use with the pipes on stops of an organ, it will be apparent that it is of value in preventing the improper actuation of other air-pressure-operated devices found in organ construction.

The valve casing 18 and electromagnet 23 are both exterior to the chest, which facilitates wiring and mounting and provides good accessibility for inspection and repairs. I
