'To allwir'o'm t may concern itknoivn'that L'EDWIN Wnnrn, a subject'y of ,tlieGrand Duke of Baden, and a resident'o'f Freiburg, inthe Grand Duchy of Baden,y yGerinan ljlimpir'es have invented cery"tain new' a useful Improvements in Vari- "avble Automatic Stop-Controls for Musical Instrume'n'ts,fofY which the-'following is a full, clear, v'and' exact description, whereby j use thev same. 2
' The finventionrelates to musical instru- `ments andmore particularly to the control ofv` the stopscfa/n korgan wherein' the stops" lfmay bef. controlled automatically from a musicl sheet ormanually or wherein during the controlby: the automatic action of the music sheet-,1amanualv operation may be .effec-fedi. Air
f The object of the invention is to provide a Vmechanism by lwhich 'the stop effects off'an .organ may' be produced automatically from the perforatedmusic:sheet or manually.
A further object is to provide a mechanism jby vvhich during the automat-ic oper-.- ationfof the organ, the stop effects may be v automatically controlled from the music sheet or manually controlledu'ith the automat-ic control "of thel music sheet inoperative lormamially controlled during the automatic control froni the music sheet.
. Referring to the drawings: Figure 1 is any Qneskilled in the art may make and i Specification of Letters Patent.
fajdia'grann'natic vieu' shown in partial perspectivev illustrating the various elements employed' in conjunction with the trackerboard. y
In automatic musical instruments including organs, it has been common .practice to employ a perforated music sheet in con] uncmusic sheets have been employed for pneu- 'matically actuating mechanism to produce stop effects with provisions for causing the v'automatic control to be inactive. so that -The "mechanism hereinafter .described fmanual stops might be used in the ordinary tion with' a 'tracker-board and perforatedllustrates in' diagrammaticA form a trackerl STO-CONTRL FOR MUSECAL'NSTRUMENTS.

board and perforated music sheet as one means for automatically operating an instrument.
lt is one of the'principal objects of the present inventionA to arrangea mechanism by Which the stop effects ivill be automatically secured or may be made inoperative during the automatic-operation `of therinstrument and providing in conjunction therewith manually controlled mechanism which will secure stoj'i effects either with theV automatically control-led stop mechanism in action orl in inoperative condition.
Referringl tothe "drawings, the numeral l, denotes a tracker-board over .which passes the punchedmusic-sheet 2, Kvliich. of' course, has suitable mechanism, for moving it yover i the tracker-board. `Conveniently arranged in the tracker-board are openings connect`- ing through suitable tubes 3,4, with valve mechanisms 5. 6, arranged insuitabltr rela-'Ln tion vvith reference to a- Imain suctioir- \r pressure device not specifically shownherein, but connected vvithithe valve mechanisms through a suitable conduit 7.
The valve mechanisms 5. 6 referred to are or' valves not herein specifically described but ivhich obviously may be used in conj uncv tion with a second series or bank of pipes or reeds in conjunction with a. separate stop chamber not illustrated herein. `the description herein set forth being confined to one stop chamber and its bank of pipes or reeds.
The suction or pressure through the conduit 7, and its action upon the valve mechanism is controlled as illustrated herein by suitable valves 8, which, through levers 9, may be moved by stops l0. (Only one stop and appurtenant parts is illustrated.) These stops7 for convenience, are arranged to have tivo positions. One position is illustrated in the drawings, wherein the valve S, is pulled avvay from its seat by the connections 11, 12, and is maintained in open position by. a spring or detent 13, coperating u'itha notch 14, in the spindle of the stop. A second notch 15, makes it possible to press the stops 10, inwardz closing the valve 8, and retaining the partsin closed position.`
The valve mechanism 5, 'is connected, through a conduit 16, Iwith a collapsiblebellows 17, which hasits movable board connected through a leverrlf 8,\.iv`ith the connec-V n l vtionh19fof a valve 20. These valves control stop chambers 21.appurtenant to each of the vsets of playing pipes of the instrument.
'The valve mechanisms 5, andv 6, are co.- operative in their relation one with the other, whenever the valve 8, is open Aandthe instrument is subjected to the automatic action of the perforations of the music-roll and its tracker-.board 1. As an example: When .an opening in the music-sheet'passes the opening in the tracker-'board corresponding with the vconnection 3, a diaphragm 22, connected with a valve s indlel23, and valve 24, is subjected .to atmospheric pressurev and by preponderance of atmospheric pressure over the exhaust of the tube 7, through the windv chest 25, -causes the diaphragm 'torise, carrying the. valve' 24, away Afrom its seat 28, and
l subjecting the wind-chest 29, to the pressure ofthe wind-chest 25. As soon as the valve 2,8, leaves its seat, a suction is4 created upon the upper side of the diaphragm 30, through the connecting passage 31, and said valve 24,
is held in its upper position against a seat 32.
' The conduit 16, connects the bellows 17, with the wind-chest 29, and therefore said bellows 17, are collapsed, due to the suction of the wind-chest. The collapsing of the bellows 17,
' through its lever18, pulling against the`stop v33, 'upon'the connecting member' 19, opens the valve 20, and inasmuch as, the ,windchest controlled by said valve 20, is connected with the main. pressure or suction device, the playing pipes or reeds thereof will be influenced. This position of the parts will be maintained until an opening in the music-sheet passing a corresponding opening in the .tracker-board opens the tube 4 to at- 'mospheric pressure. Thereupon, the diaphragm 34,.will rise, due to preponderance of atmospheric pressure over the suction in the chest 25, and will carry with it the valve 35, which, subjecting the wind-chest 36, to
th'e -suction of the chamber 25, will cause an lower side of the diaphragm 22, througha equal pressureor suction through an opening 37, upon the under side of the diaphragm 30. The pressures being thus equalized on opposite sides ot the diaphragm 30, the
bleed-hole 38, which is connected with the wind-chest 25, will cause the valve 24, to v drop.
lJust as'soon .as this is effected, the valve 35, will be returned to its normal position, inasmuch as, the lower side of its diaphragm 34,' is subjected to the suction of the chamber 25, through the bleed-hole 38.
4From the above, it is apparent.that the openings in the music-sheet will cause an automatic opening of the valve`20, and a corresponding closing thereof through the ac-` tion of .the valve-mechanisms 5, 6, whenever the valves 8, are-held in openl position by virtue of the position of the controlling stops 10.
It is understoodthatfthere .is a controlling stop and. appurtenant ,valve mechanism such as described forcontrollin' leach'set ol"v reeds or pipes to secure ystop e ects thereof, and there may be such a'controlling stop .and valve mechanism to each manual of the instrument or for anydesired series of ordinary organ stops s o that various stop effects and combinations thereof may be secured in automatic 'play'v g and may likewise be varled by the manual operation. J
The connections 19, of the valve or valves 20, extend to the movable board 39, ofl a pneumatic bellows 40, which latter, through a conduit 41, is connected with .a valve action-42. This valve'action 'has a valve corresponding 4to each of the valves above de- .l
scribed in connection with the stops 10, and
each of its valves-are correspondingly con-- nected with pivoted leversl 43, which might well be termed console stops and which are located appurtenant to the console of the instrument. These stops 43, as illustrated, are
pivoted' as at 44, and have one end 45, acting i as valves, atthe end'of the conduits 46. For convenience Vthey are illustrated as con- 47, cop'erating with a spring 4 8, so that they may be held in either'open or closed position with reference to the conduits 46.
` The conduits 46, lead to the underside of' the diaphragms 49, which control the actionv -trolled, as to their position, by a -projection 40, will -ppen thev valves 20, and subject the corresponding sets of pipes orreedsof the stop chambers 21, to the full action of the main suction irrespective of the automatic opening eii'ects lproduced by the collapsing of the bellows 17.
It is apparent 'from the above that even ,though the automatically actuated valvev mechanisms 5, 6, are in operation, the 4manually operated console stops 43, may
be movedto vcollapse the bellows 40, and
vary the actionwith reference to the playing of anviset of pipes or reeds.y On the other hand, if the controlling stops 10, are
pushed inward, closing the valves V8, the',
manually operable console stops 43, may
be moved, controlling the valves 20, independently -of the valve actions 5, and 6.
From the above description, it is apparent that the apparatus provides for the automatic operation for thestop effects duringthe automatic operation of lthe instruvalve for said chamber,
vmay be ment (as -shovvn through the perforated music roll and tracker-board) and at the same time provides for a manual control of said stop effects either in conjunction With or independently of the automatic operation. Furthermore, the automatic action to produce any of the stop effects may be completely cut ofr`.through the controlling stops 10, and 'a direct manual control to secure anyv stop effect may be obtained through the console stop levers 43.
Obviously, thedetails of construction and the arrangement may be varied Without de,-
4parting from the spirit or intent of the invention and it may be applied to an instrument having. one Q'r more manuals, giving practically all combinations of stop effects. For convenience and to simplify the showing of the mechanism, it has been illustratedin simple diagrammatic form.
