Application filed December 30, 1997. Serial No. 408,502.

To all whom it may concern Be it known that 1, JOHN T. AUSTIN, a citizen of the United States, and resident of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Organ- Actions, of which the following is a full, clear, and exact specification.

Ihis invention relates to improved valve mechanism for operating, or controlling the operation of, the various. note sounding devices of musical instruments. By this invention each row of perforations in a valve sheet, or perforated note sheet, as it is commonly called, serves through a single tracker duct, and a single primary, to selectively cause the sounding of the corresponding note in different stops or sets of pipes of an organ, the selection being determined by the strength of impulse of the primary, which in turn is determined by the relative sizes of the succeeding perforations. Thus the smaller perforations may be utilized to control the notes of one stop or set of pipes,

" while the larger perforations may concurrently serve to control the notes of a different stop or set of pipes. In this way the solo or melody notes of a musical composition may be represented on the valve sheet by perforations of one size, while the notes of the desired accompaniment may be represented in the valve sheet by perforations of a different size, with the result that the solo or melody notes, and the accompaniment notes, may by the automatic selection of the perforations themselves, be played on different stops, suited to the solo and accompaniment, respectively, even though the different sizes of perforations follow each other in the same line, acting upon a single duct and primary.

This invention also includes a combined electric and 'ineumatic system, operated by the aforesaid single primary and tracker duct, in which. any of the notes selected as above described may be played by the com hiucd electric and pneumatic systems, or by either of them alone, in addition to the couplers and other combinations obtained by the ordinary coupling or composition device: of an organ.

Figure l of ,the drawings is a plan view of a group of these improved actions. Fig. 2 is an end view in section taken on the line 2 of Fig. 1, showing the valve and contact devices at rest. Figs. 3 and 4t are end views similar to that of Fig. 2, but showing the action in the different phases of its operation, due to the differing sizes of the succeeding erforations in the valve sheet. Fig. 5 is a ragmentary side view of an action chest, showing an arrangement of the electrical connections for the separate actions. Figs. 6, 7 and 8 are sectional end views similar to those of Figs. 2, 3 and 4, showing modified embodiments or applications of the invention. Fig. 6 illustrates the employment of two springs for the valve lever,

which by their situation relative to the valve leverallow the two ends of the latter to be lifted in the desired sequence. Figs. 7 and 8 lifted by the initial or lighter pressure through a small perforation, is closed down again upon the lifting of the other end of the lever, so as to avoid, when desired, the concurrent sounding of the respective notes controlled by the two ends of the lever.

The controlling valve sheet or note sheet 10 operates in conjunction with the tracker 11 provided with the ducts 12. The note sheet is provided with note perforations 13 and 14 of different sizes, this difierence in size enabling them to sound two different notes, or the same note in two different stops, as above indicated. By this feature I am enabled to. employ a stop suitable for the playing of the solo passages while at the same time playing a suitable accompaniment on other stops, using the same tracker ducts both for the solo and the accompaniment stops.

Each of the tracker ducts 12 leads to a primary pneumatic, which in the embodiment shown in the drawings consists of a die ,hragm or pouch 16. Those primary pneumatics are preferably grouped as shown in Fig. 1, in staggered or alternated succession, in order to get the different actions closer together, while providing for each action a di:-1phragm or pouch of ample size. Each diaphragm rests-beneath or operates upon a double acting valve or contact closing member 18, which in the embodiment herein shown is a lover provided with valve pads or pallets 19 and 20, covering the open-. ings of the windways 21 and 22, respectively. These windways lead to the mouth pieces of different pipes or other note-sounding devices, or to pneumatic valve mechanismsfor controlling the sound of the said devices, all

, of which maybe of ordinary. or wellv known construction, and therefore are not. illustrated herein. The pouches 16 are provided with suitable bleed holes to enable the air to be exhausted from the tracker ducts 12 when the trackerapertures are covered by carried by the lever; and this action of the air pressure is yieldingly' opposed by a spring or similar yielding resistance acting against a different portion of the length of the lever, thus causing the least resisting v end of the lever to lift advance of the other end, and thereby opening one of the windways in advance of the other; andif the lever is provided'with electric contacts, closing one of those contacts in advance of the other. For conciseness and definiteness of expression, these bars or levers 18 are herein termed levers, and the described two-part or two-step or two-period action of the lever is herein designated its two phase movement. For the same purpose, the term indirectly opposed is employed to designate the action or relation to the lever of the forces which'act upon the lever at difierent portions of its length. Thus the ends of the lever are made to riseand fall by the tilting of the lever upon a kind of floating or indefinite fulcrum point under the control of theindirectly opposed forces and according to the varying percussive strength of the air pressure admitted through the different'sized perforations of the note sheet. Obviously the expansive or percussive force of the small volume of air that can be admitted through a small perforation is less than the similar force due to the admission of a larger volume of air through oneof the larger perforations.

As illustrated in most of the figures, the yielding opposition or resistance to the active operating movementimparted. by and through the pouches 16, consists of a spring 40 engaging each of the levers 18' approximately at the center of its length while the pouch or diaphragm 16 is disposed toward one' end of each lever from itscentral spring-pressed portion. Thus the initial action of the diaphragm is to lift the end of the leverto which it isnearest', as shown in Fig. 3, thus opening the windway 21, while the opposite end of the lever is held down by the action of the spring 40, thus keeping the windway 22 closed. The. respective levers are loosely held in proper register with the windways by means ef guide'pins 42, projecting through slots in the ends of the levers.

Limit stops are provided for lim ting the upward movements of each end of the levers. In the present instance the fixed contacts 27 and 28 constitute the limit stops. Or the guide pins 42 maybe made to servetas limit stops, by providing; them with a head, or by bending the uppenend over, similar to the contacts 27 and..28, especially when using the levers only for pneumatic systems, and without the electrical attachments.

The dilferenti stops orsets of note sounding devices maybe near to, or distant from, the actions herein shown, the windways 21 and 22 being extended to any desired extent by means of. tubes. The tracker bar 11 is commonly appurtenant to the console of the instrument, which may be at any convenient point relative to the primary action chest, the ducts 1 2.being extended to the required extent'by means of tubes.

In many instances, particularly where the pipes other note sounding devices are located at a considerable distancefrom the actionfchest, it is desirable toemploy electrical contacts and connections between the primary actions and the stop or pipe actions. These electrically operated stops or pipes maybe employed either with or instead. of the pneumatically operated stops or pipes. Hence it is desirable to provide a primary action that shall be capable of operating pneumaticstop devices or electric stop devices. Therefore I have shown herein as the most complete and comprehensive embodiment of the present invention, an arrangement which is adapted without any change to operate pneumatic and electric stop devices, either independently, or in conjunction.

The double acting lever 18 serves also as a contact lever, being provided with the , contacts 25 and 26, which coact with the terminal contacts 27 and 28, respectively, which are preferably supported as herein shown, by being driven into holes inthe base 30, with their upper ends extending over their respective coacting contacts 25 and 26 of the contact lever 18, as best shown in 5. ing these contacts in a comprehensive electric' system their lower ends 31 and 32 are extended below the base 30 and are provided with connecting wires 33 which are inde pendently connected with the respective magnets or solenoids 34, or other electrically operated devices for causing the respective pipes to sound. The several electric circuitsmay be united in a battery wire 35,

leading to the battery 36, from the other As a convenient way of connectside of which the battery wire 37 connects with the wire 38, from which branch circuits are extended for the respective actions, terminating in the contacts 25 and 26. A convenient way of thus distributing and completing these circuits is shown in the drawings, in which the springs 40 of the respective valve and contact levers are utilized as a part of the circuit. These springs as herein shown extend downwardly through, and are secured in the base 30 and are in contact .with the battery wire 38. The upper arm of each spring 40 extends over its valve lever or contact lever, and serves to yieldingly hold that lever in its inoperative position, in whichit closes the windways 21 and 22 and leaves the contacts 25-27 and 26-28 open, as shown in Fig. 2. In order to complete the electric circuit between the springs 40 and the respective terminals '25 and 26, the bridges 41 are preferably employed, each bridge being provided with a hole through which its spring 40 passes, extending therefrom to the ends of the valve or contact lever 18. The ends of the bridge may form the contacts, or they may be, as

herein shown, provided with supplemental.

contact pieces 25 and 2G,made of platinum or other suitable metal.

In the embodiment of the invention shown herein the windways 21 and 22 open into a vacuum chamber 45, in which the valve levers 18 and their appurtenances are located. The chamber may be made in any convenient way, as by the frame 46 and the cover 47 which may be of glass in order to enable the working of the valves to be observed. It will be understood, however, that atmospheric or higher pressure may be employed, since these, like other pneumatic devices of this class, are operated by difl'erencesin air pressure, and the substitution of different pressures is a matter well within the knowledge of those skilled in this art.

In some cases it may be possible and desirable to place all of the action pouches in a single row at one side or the other of the action chamber, in which case the ends of the levers which are disposed on that side will all be lifted first, and the electric circuits and windways must be arranged accordingly, but in order to gain compactness and ample size and power in the actuating pouch, I prefer to arrange the pouches in two rows, alternately on opposite sides of the action chamber as herein shown, in which case the ends of the levers which are lifted first will obviously be similarly alternated. In other words, the end of each lever to which its pounch is nearest, will be the first to lift under the action of the small perforations 18, hence the windway and the electric contacts nearest to that end must be connected to the note sounding devices, generally the accompaniment devices, which are to be eperated by the small perforations, thus making those windways and contacts come alternately on opposite sides of the action chest as shown by the alternated positions of the wires 27 and 28 in Fig. 1. The operation of these devices is as follows, it being assumed that the tracker bar and note sheet are in the open air, under atmospheric pressure, and that a suitable vacuum is main tained in the action chamber 45 For convenience of explanation it is also herein assumed that the windways 21 and 22 and their associate primary pneumatic 16 with its connecting tracker duct 12, shown in the sectional views, are arranged to sound the note C in two diiferent stops of an organ, the windway 21 leading to the C-pipe of a stop suitable for playing accompaniment passages under the control of the small perforations 13, while the windway 22 leads to the corresponding C pipe of another stop suitable for playing solo parts under the control of the larger perforations 14.

The contacts 27 and 28 and their connecting wires 33 are arranged in two separate circuits, which by means of two difierent sets of the magnets '34, work two different series of stops, the contact 27 operating an accompaniment stop, while the contact 28 operates a solo stop. Thus the two windways and the two contacts operate four stops or sets of stops, which may be put in or out of action or coupled in any wel known way, as for example by means of stop knobs appurtenant to the manuals of the organ, so that the organist can sound some of the solo notes on one solo stop by means. of the windway 22, andsound other solo notes on a. different solo stop by means of the electric contacts 28.

As illustrated in Fig. 3, when one of the small perforations 13 reaches the tracker duct, the air is admitted through that duct to the underside of the pouch 16, and being of small lifting power raises only the left hand end of the valve lever 18, thereby opening the windway 21 to the vacuum in the chamber 45 and operating the note C of the particular stop with which that windway may at that time be in communication. This movement of the left hand end of the valve lever also closes the contacts 26 and 28, thereby energizing the solenoid 34 of the pipe C in the particular stop or stops which at that time may be drawn or coupled for action.

When one of the larger or solo notes 14 reaches the tracker duct, asshown in Fig. 4, the increased pressure lifts both ends of the lever 18, thus opening both windways and closing both electric contacts and thereby found preferable to employ the pneumatic windways 21 and .22 for operating stops which arevsituated near to the'console or w action chest,-e1nploying the electric contacts and circuits for .operating the stops which are more distant, so asto more nearly synchronize the action of widely separated stops. By thus providing the levers 18 with valves and with contacts, thereby adapting them for use either with pneumatic or electric actions, or both, they may be manufacturedin large quantities, with out considering the character of the parti'cular actionor organ with which they may happen to be used. Thisuniversal type of action also facilitates the'subsequent extension of the organ; for example, an organ may at first be provided with a limited num ber of stops operated pneumatically through the windways 21- and 22. Later on itmay be found desirable vto add more stops, which may then be operated electrically by means of the contacts 25-27 and 26-28, thus saving the cost ofncw actions.

The windways 21 and 22 may be combined or connected in any well known way by means of pneumatic couplers. The circuit wires 33 may also be connected or combined or extended by means of electric couplers in various ways which are familiar to those skilled in this art. i

p The springs 40 may be dispensed with by suitably shaping andwe'ighting the lever, so that, its lighter endwill be lifted first 'under the actions of the smaller perforations 13, the heavier end remaining closed until operated from the larger perforations 14. When" it is desired to provide such a weighted lever with electric contacts, the absence of the circuit carrying, function of the spring iO may be compensated for as shown by the dotted line variation in form of the spring40, in Figs. 2, .3 and 4. In'that case, the spring 40 is shortened, terminating as shown by the end 89,.shown in dotted lines, the end of which extends adjacent. to the contacts 25 and 27,21 similar row or series of contact wires tOjand battery wire 39' being employed in connection with the contacts 26 and 28 at the opposite ends of the v valve levers. The contactpieces 25 and 26 form bridges, which, when the respective I ends of the valve lever are raised, connect in circuit the ends of the contact wires 39 and the contact wires 27 and 28, as shown in Figs. 3 and 4. v

Instead of employing a single spring a 40 for each of the valve levers, two springs may be employed, as shown in Fig. 6, one

at each end of the lever, and of such tensets or series of springs 51 and 52, and battery wires 53 and 54 are employed, one set at each side of the action box, and arranged at the ends of the respective levers controlled by them. The coacting contact wires 55 and 56 are similar in arrangement and position to those shown in the previous fig ures, but extend somewhat higher above the levers, so that the respectivecontact springs 51 and 52 will pass beneath them. The

pneumatic diaphragms or pouches 58, and

the contact springs 51 and 52 are disposed unequally relative to the valve lever, so that one end of the lever is lifted before the other under the influence of the small perforations, as illustrated in Fig. 6, the stronger impulse communicated to the'pouch by the ripening of the larger a ertures operating as before to lift the right and end of the lever to open the respective windways 59 and 60,

and thus sound the corresponding notes.

In the embodiment represented'in Figs. 7 and 8, the pneumatic diaphragms or pouches 62 are shown to be situated "approximately at the center of the length of the levers 63, the latter being held down by p a single spring 64, at one side of the pouch. Any suitable guides, as the pins 66, may be employed for guiding the lever during its lifting movement. A limit stop 65', consisting of a bent pin or staple, extendsover the valve lever adjacent to the center of its length. The initial or light impulsegiven to the valve lever by the passage of one of thesmaller perforations 13 over the tracker,

,raises the left hand end of the lever, .as

shown in Fig. 7, thus opening the windway 68 and sounding the corresponding note, the lifting movement of that end being arrested by the limit stop 65. When the stronger lifting impulse is'given from the larger'perforations 141 the right hand end of the lever is lifted as shown in Fig. 8, thusopening the windway 67, and sounding the corresponding notes. This second lifting movement of the lever turns it on the limit stop 65 as a fulcrum, thus lowering the left hand end of the'lever and closing the left hand windway 68. During the initial lifting movement of the valve lever shown in Fig. 7, it operates as a lever of the second order, whereas dering its succeding movement, shown in Fig. 8, it operates as a lever of the third order. It may sometimes be considered desirable thus to avoid concurrent operation of the notes controlled by the two ends of the valve lever, as is shown in Fig. 4; and one of the advantages of the arrangement shown in Figs. 7 and 8 is that each of the windways 67 and 68 is closedwhen the other is opened.

' tern, according to the style or modification adopted; and when assembled they may be disposed uniformly, or the alternate levers may be reversed end for end, as indicated in Fig. 1.

For completeness, and especially for definiteness of description, it is here assumed that the larger perforation 14 of the note sheet represents or calls for the sounding of solo or melody notes, and the smaller perforations 13 represent or call for the sounding of accompaniment notes of a composition. This, however, is in no sense a necessary' limitation, since either of the difi'erent size perforations may be employed for any stop or stops.

The two-phase, or two-fold movement of the valve levers or contact-making levers 18 is or may be the resultant of several factors,

' namely the actuating impulse througn the pneumatic 15, the yielding resistance afforded by the springs 40, the relative strength of the pneumatic, and the resistance, and

their respective points of a plication rela-,

tive to each other and to t e valves. The drawings show some of the possible variations in the manner of combining and applying these varying factors so as to produce the desired movements of the valve or contact making levers. It will be obvious, however, to anyone skilled in this art, that the construction, arrangement and relation of these parts may be varied in many ways, within the meaning of the claims, which are intended to be of the broadest scope and not limited to the specific constructions and embodiments which are herein shown as being illustrative of the invention.
