ELECTRlCALLY-CONTROLLED MAGNET AND VALVE FOR PIPE-ORGANS.

SPECIFICATION forming part of Letters Patent No. 536,975, dated April 2, 1895.

Application tiled April 7, 1894. Serial No. 506,711. (No model.)

To all whom t may concern:

` Be it known that we, EDWIN S. VOTEY and WILLIAM D. Woon, citizens of the United States, residing at Detroit,l county of Wayne, State of Michigan, have invented a certain new and useful Improvement in an Electrical Magnet and Valve `Controlled thereby for Pipe- Organs; and we declare the following to be a ful1,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, reference being had to the accompanying drawings, which form a part of this specification.

Our invention has for its object an improved electrical magnet and its attendant features for pipe organs, the same being especially designed and adapted for this particular work, and to this end our invention consists of the construction, combination and arrangement hereinafter specified and claimed, and illustrated in the accompanying drawings, in which Figure l is a view in diagram and vertical Fig. 2 is a view of the electrical magnet proper, its parts being separated to more clearly distinguish the same. Fig. 3 is a plan view of the magnet.

The special object which we have in view in the construction and arrangement of this electrical magnet is to control the operation of a pneumatically operated valve by controlling the passage to and from the pneumatic, and to accomplish the desired results electrically at any required distance from the key board.

The construction and arrangement of a single magnet operated by a single key to control a single pneumatically operated valve will suffice to illustrate our invention, as it will be readily understood that we contemplate the employment of a series of similar magnets similarly operated to control a series of pneumatically operated valves respectively.

Accordingly A represents a key connected in any ordinary manner with a lever B, said lever being connected by a rod b with a spring B', which is in permanent electrical connection with a battery or other electrical source of supply, B2, as by means of the conductors h2 A is a block upon which the spring B is supported. A2 is a similar block supporting a spring 192, normally out of contact with the spring B and in circuit with a conductor 193.

C represents our improved electrical magnet.

C is the core, to the poles of which is iixedly engaged a plate C2, preferably perforated as shown at c and c, for the passage of air therethrough.

C3 represents the windings on the core, consisting of the conductors h3 and 54, the battery B2 intervening between the conductors b and 54.

O4 is a metallic armature, made attractable by the poles of the magnet when the magnet is in electrical circuit with the battery. This armature is preferably made solid, so that no air can pass therethrough, and is preferably covered with leather to make its operation noiseless.

C5 is a base, preferably cylindrical, and threaded on its exterior, the same being constructed with a lateral passage or channel c2 and an exhaust passage or channel c3, which may open vertically through the lower end of the base C5, as shown in Fig. l, although the precise direction of the channels 02. and c3 are not vital to our invention. The base C5 is constructed to form a seat for the armature C4, as shown at 04, upon which the armature normally rests when the circuit is broken closing the exhaust passage c3 in the base C5.

OG is a thimble, threaded at its lower end and having a threaded engagement with the base C5 the thimble holding the magnet core and its windingsin place, the perforated plate C2 extending thereunder as shown in Fig. l. This thimble is open at its upper end, allowing air to pass therethrough and through the perforations of the plate C2.

D denotes a wind chest connected with the air supply in any ordinary Way.

D is the base of the chest, into which the base O5 of the electrical magnet is engaged.

d is a channel in the base D communieating through a channel d with a pneumatic E. The channel d also communicates with the orice or channel c2 in the base C5 of the magnet.

ICO

F is a wind box communicating with the pipes G, communication being controlled by a valve f II is an air passage communicating through a channel h with an air duct I communicating with the wind chest D. The valve f is connected with a rod f resting upon a leather .I in the air passage H, which is lifted by the admission of air through the air duct I and channel 71.

The special construction of the wind box F and the particular mechanism shown in connection therewith for operating the valve f, forms no feature of our present invention, as any form of wind box and mechanism to control its communication with the pipes may be employed within the scope of our invention, pneumatically operated by air through the passage I. The passage I communicates with the wind chest D through a passage t and exhausts through a passage i2 K and K are valves controlling the passages 't', i2 said valves connected by a rod K2 with the pneumatic E, said pneumatic on its inflation closing the valve K and opening the valve K and vice versa.

The operation of the device will now be understood.

By pressing the key A the spring B is lifted into contact with the spring b2, closing the circuit through the magnet C, by which means the armature plate C4 is lifted from its seat, closing the apertures 0, c in the plate C2 thereabove, thereby cutting off the inflow of air therethrough from the chest D into the passage d and into the pneumatic E. Pressure from within the pneu matic being thus relieved the pneumatic will exhaust by gravity, and the pressure thereupon of the wind in the chest D. A spring L also bears upon the rod K2 to hold the valve K upon its seat. The armature CL1 being lifted the pneumatic E is permitted to exhaust through the channels D, r2 and c3, opening the passage t by which wind is allowed to pass from the chest D into the duct I and airchamber or passage H t0 open the valve ff causing the pipe to speak. On releasing the key A the spring B drops to its normal condition, breaking contact with the spring b2 cutting the magnet out of the circuit. The armature C4 then drops to its seat, cutting oft' the exhaust ot" vair from the pneumatic E and allowing air from the chest D to pass through the perforations in the plate C2 to infiate the pneumatic E closing the passage 1, and allowing the duct I to exhaust through the passage f Our invention is not limited to the employment of our improved electrical magnet in connection with the other particularfeatures of the pipe organ with which itis shown and described in this present application, but we contemplate broadly the use of ourimproved electrical magnet herewith shown to any purpose to which it may be found adapted.

In another application filed simultaneously herewith, for example, Serial No.`50G,7l5, essentially the same electrical magnetis shown in other connections, in some of which it is not always requisite that the plate C2 should be perforated.

It will be observed that the base C5 with the thimble CG constitutes the case of the magnet valve. le prefer to make all parts of the electrical magnet of metal. The base and thimble constituting the case may be made of brass. The base C5 ofthe case, it will be seen, is formed with a fiange or seat Q, upon which the plate C2 rests, the thimble when screwed into cngagement with the top of the base binding said plate firmly upon said flange. Being made ot' metal, it will be evident, that all the parts are accurately related one to the other, and that there is no liability whatever of the parts getting out of their proper relation to each other, as this construction avoids all swelling and shrinkage which might occur if the valve case were made of wood, in which event the valve of the magnet might become inoperative. The parts are made in duplicate, all the different elements being the counterparts one of another. No adjustment whatever is required after the parts are put together. Atmosphere does not affect it, and yet the parts may easily be separated if desired for cleaning or other purposes.
