The present invention has relation to pipe organs and consists of improved means for effecting the operation and the control of the stops of the organ. Heretoi'ore the stop keys 5 are usually separately and selectively operated to place the stops in both the on and ofi' positions and in some instances means have been previously proposed whereby the stops are separately and selectively brought into lo the on position and then collectively returned to the oli position.

According to the present invention, the stops are separately brought into the on position by selective operation of the respective stop key and then all the stops set in the on position, are thrown back to the ofi' position by a single operation or touch of anyone of the stop keys. All the stops are so arranged and associated with each other that upon initial or first touch oi a stop key the stop associated therewith is brought into the on position. Any number of stops can be brought into the on position and in which position they will remain until any one of the stop keys is operated or brought to a point beyond the position it is in after the first or initial operation. The operation of these stop keys may be termed a double touch action, that is, on the first touch of the key the stop is brought into the on position and then a double or advanced touch of any one of the keys, whether or not this key is in the on position, will elect operation of a control device which will cause operation of the actuating means for the various stops. Each stop has its own actuating mechanism comprising an on and an oilE magnet operated through a suitable electric circuit and each magnet in turn eiiects operation of pneumatic actu* ators which are arranged to open ports to ad.- mit compressed air to effect operation of the mechanism which causes the stops to open or close to bring the same respectively into the on or off positions.

55 The mechanism or means for actuating the individual stops is of any suitable kind and there is such a mechanism for each stop. According to the present invention a common control device is provided and designed so that this single control device will operate to 1930. Serial N'o. 461,373.

control one or more stops. This device and the means comprising the double touch a"- tion associated with the stop keys form essential parts ot' the present invention. The improved device and means include the usual stop keys, each being connected with a spring actuated cleaver. Each stop key carries a movable contactor which is brought into contact with a lined contacter when the double or advanced touch is given to the key. This latter contacter completes the electric circuit which eiiects operation of the olil magnet to throw the on stops into the ofirq position. In the first touch et the stop key the contact is not made as above stated; therefore said electric circuit is not completed but in this first touch, either by electrical or mechanical means, the selected stop is brought into the on position. Y

An embodiment of the invention will be described hereinafter with reference to the accompanying drawings; whercin- Figure l is a sectional view showing the individual stop actuating mechanism together with the control mechanism and the stop actuating means7 the latter being shown diagrammatically; and

Figure 2 is a diagram showing the arrangement of the different apparatus or means employed and also the arrangement of the electric circuits.

The salient feature of the present invention is the double touch means or mechanism employed for actuating individual stops and the common associated control device or mechanism forms another part of the invention. Any well known means 'for operating' the stops may he empiovcdv and therefore such means are only illustrated diagrammatn ically in the accompanying drawings.

Referring to the aforesaid drawings the means 'for actuating the individual stops are similar in constructon and arrangement and it will be understood that one of such devices is employed for each stop. Said actuating means comprises the key l which is carried bythe Cleaver 2 pivotally suspended from a part of the organ key-board framework 3. The means for suspending this Cleaver includes ya hanger 4 land said cleaver is con- `ina-cnet land 61.1@

nected thereto so as to pivot on the pin 5. A spring 6 is employed to return the key and clearer to the normal or ott" position when the operation tor rcturninothe said key to the oli position has been performed, The spring tension which controls said key and Cleaver is adjusted vby -n'ieans ot screw 7 engaged within a threaded hole in a part ot the keyboard framework of the organ.

The key 1 en the underside thereotcarries an insulated resilient pad S vand which pad lies over a i.\;ed contacter 9. The key 1 carries the movable contacter 10 which is insulated trom said fixed contacter 9 by means of the insulating; pad S. The key-board frame a. iixed contact 11 which is electri- 4ally connected to the 'feed or source ot electric current by conductor 12. The concluetor 13 connects the contacter 9 with the 'magnet 141 ot' the control device 15. The latter device consists of a casingl 16 enclosing the magnet 14 and which casing is sub-divided to provide air chamber 17 and air passage 18. 'lhe control device comprises as other Working parts, besides the magnet7 a movable block 19 Which carries the movable contactors 2 0. The said block v19 is raised by means ot the pneumatic actuator device 22 which is inflated by air so as to lift said block 19 to bring the movable contaetors 2O into contact with the fixed contactors 21 which latter contact completes the circuit through conductor 23 to the off magnet or magnets 241. The latter magnets are located in the diagrammatic illustration -ot the operating means 25. As previously explainedthis operatingjr means or mechanism Will be provided with as many on and ott magnets as required to correspond with the number ot stops of the organ. As previously explained7 the on and ott' magnets are operated in the usual Way by the ordinary operation/ot the respect-ive key 1 which in said operation is not brought to a position beyond that shown in Figure l1 wherein the contaotors 9 and 10 Vare not vin contact.

In the voperation of the improved Vmeans or device, a stop key 1 is initially operated by the tiret touch in a manner common to practice, that is, pressure on the key will operate the pi voted cleaver 2 which, through the medium oi? connecting link 26 operates lever 27 and the lat-ter in turn operates a suitable device tor mechanically effecting the operation ot the means tor placing the stops in the on and ett positions. This means operates in the usual Way common to other-organ stop actuating mechanisms to vopen the respective port to admit compressed air.

ln common practice when electrical means are employed the on magnet is retained in the operative position until means are brought into action to cle-energize .said von e the @ft magnet to throw `mal or o position. WithA c the stop te itv free-aes the present invention, `the action of returning the stops to their normal or closed position is greatly simplified and therewith any combination of stops may be readily brought into action by the first or initial touch of the respective keys. To get various combinations the stop keys may be operated together or separately with the double touch and if the key or keys are held in the operlated position, the respective `magnets Will'lremainin the on position, but other stop keys then in the on position will be returned to the eti position.

position and upon operation -ot any one of the keys with increased pressure or, as herenibelfore termed, a double touch, themova'ble contacter 10 carried by the 'operated key 1 is brought into conta-ct `with the lined contaeter 9 by compression ot the insulating pad 8 which ispreterably composed otsott elastic material such, ter example, as a telt pad. TWhen the contactor-Q contacts With contacter 10, the circuit through conductor 13 is established and the magnet llQ vthe vcontrol device 1a-is actuated to niove the val-ve stem 2.8. This valve stem l .rarr-es the valves 29 and 30. The valve 30 opens the/port between the chamber 17andthe air passage `18 and Awhen said valve 30 open valve 29 lcloses the outlet port-lcf-the aforesaid passage 1S- VVhen air is admittedfthrough .passage 18the pneumatic actuator is inflated to, raise the block 19 caithe Vcontaeters 20. Centact is made Withthecontactor plate 2 2 and through this contact Velectric .circuits are established vto operate all theolimagnets Vcollectively so as to close all the open stops by the double touch operation ot any one ofthe stop keys, as previouslydeclined.

The essential feature yof 'the invention her-einbetore described is the so tern'ied double touch mechanism usedeither alone Aor conjuncti-vely with a. control device electrically .connected therewith. Both ot said means or devices may be used separatelyor together with various known means :for mechanically or electrically operating` the stops of an organ A'and it is to be understood that any modiiication, either in 'the construction or application ofthe invention here-inbe'forc described coming fairly Within the terms of the appended claims shall be covered thereby.
