It is afurther object of the present invention to combine a combination action, and unit switch action intoa unitary construction thereby reducing the number of parts and structural details. Certain embodiments of my invention are illustrated -inthe accompanying drawings Fig. 1 shows'in diagrammatical form the electrio circuits and-mechanical structure of an embodiment.

Fig. 2 is afront elevational view of anembodi-r ment comprising acombined switch and combination action of thesliding-bar type.

Fig. 5 is a section on the line 5-5 of Figs.'3'

i ,Eig. 6 is 'a'partial section along sectionline As shown in Fig. l, thestop'action comprises a series of vertical movable "slide'bars 1-'1-'-1 "each" carrying the usual set of 61 contact pins 2 pins 3. .When the barsor slides l are raised by a pneumatic motor sl-the movable contact pins 2 cooperate with the fixed contact pins 3 to close circuits fromthe keys or relays to a chest or those, skilled in thef'art;

pressing the rear projecting end 7a of theoverthe-center spring into contact with the mg q which cooperate with the set of fixed contact coupler action in a manner well understood by.

tact I'thuscauSing current flow from the generator} through the frame 22 of the stop, action tocontact 7 and through circuit 6 tomagnet 5 operating pneumatic motor, 4, to raiseYslide 1b. These combinationslides are mounted for a Q sliding or axial movement in aframe not shown in order to simplify the drawings. This sliding movement at 90 to the movement of-the v'erticalbars or slide members 1a and 1b.; I As illustrated, the combination slides a to the right by a series of springs such as is indicated by, reference numeral 18. 4 Theyare actu ated toward the'left bya series of pneumatic ag tors under the control of setter buttons or piston; only one pneumatic motor13 and its corresponding controlling piston or button locbeing illustrated for the purpose of clarity. r I The pneumatic motor 13wh'ch has its lower ,portion' movable is controlled in the usual manner by a conventional action box 13a having the usual magnet,15. w ,1 Pneumatic motor 13 wheniactuated pulls down on the left handend of the bell crank 14. mounted on a fixed pivot at, 14a; The vertical portion of the tension "of spring; 18. This action occurs when setter button or piston 16 is pressed and causesmagnet 15to become energized, The other combination bars 12 and12a are similarly capable of a sliding movem'entto the left under control of the'pneumaticmotors and combination setterbuttons similar. to the one shown connected to the slide bar 12b; Each of-the horizontalslide bars, or combination of bars, carry "a serie'sfof resilient contact wires or members 17a,]1 'lb, 17c,

each one of these adapted tocooperate with a I pair of hooked contacts carried by thevertical slidebar. aThese resilient contact members l'la,

17b, 170 are so mounted at such a positionon the combination bars so that when the same arefin normal position to the right which is maintained by tensionsprings such as shown atlB, they are engagedby one of the pair of cooperating hooked contacts to suchan extent that they are somee biased 75 1 what flexed or biased and, therefore, tend to remain in an electrical contacting relationship with the particular hooked contact member irrespec tive of the vertical movement to oil? or on position of the vertical slide bar which carries the hooked contact members. More specifically, as shown in the drawings, the resilient contact 17a is shown in an engagement with the upper contact hook 100. of vertical slider 1a, and resilient :contact 17?) is in a resilient engagement with the lower hook contact 11b of thevertical slide member.1b,. and

they will remain in this engagement irrespective a combination setter-button such as 16 in the manner illustrated as the pneumatic motor 13 illustrated'connect with the bar 1217, such'movesment' will free the resilient contacts 17a, 17b-and combination slide bar underitscontrol again assumes its normal position" to the rightcausing the series of resilient contact members carried r ries the hooked contacts.

thereby to engage the particular series of hooked contacts which are at-that time in a favorable position forsuchan engagement. This position of the hooked" contacts will be controlled by the position of thevertical slide memb'enwhich car For instance, if itis assumed thevertical slide member 1a is raised and the stop controlled thereby is in on? position and the combination setter-button which actuates thecombination slide bartotherleft is momentarily pressed; the flexible contact 17a will be carried out; of engagement with the hooked contact 10a,a nd when thecombinationslide 12 again moves to its-normal' position to'the right, theiiexible contact 17a will then become engaged with. the, lower hooked contact member 11b of thispah' where it will remain irrespective of the subsequent movements of the stop slide bar is.

As illustrated in connection with the stop slide member la, all of the upper hook contacts are connected in parallel to acommon lead or conductor 19 which is connected to the oil-magnet 20 of the stop cont-roldevice on the console. Similarlyithebottom hook contact members are all connectedin parallel by the circuit 21 to the onmagnet 22 or the stop action which controls the slide 1a All of the flexible contacts carried on any one of the horizontal combination slidemembers, are connected for simultaneous energization by a relay, one relay being provided ,for each of the combination slide members as s own by the flexible members 17a, 17b, 170 which are'connected through conductors 23, 24, and 25,

to relay contacts which are simultaneously closed the stop contact 7 and thereby causing the stop Slide member 1a to move to the off-position due to the open circuit through conductor 6 and the consequent ceasing of operation of the pneumatic motor s. In a similar manner all stop slide bars which have their upper hooks engaged by the resilient contact members carried on the combination bar 12 and which are energized by coinbination button 27, will be returned to the onposition, if they are on, while any stop slide bars which have their lower contacts engaged will be automatically moved to the on-position.

While the stop control device 3 is illustrated with a direct electrical action for moving it to on-or-ofi-position, it is to be understood that the of any vertical movement of the slider bars 1a and 1b as long as the combination ;bar;. 12, which. carries resilient contact numbers 17a and 17b, remains in the position shown in which-it is? biased to the right by means of the spring menn. ber 18. If, however, any of the combination bars 12a or 12b are moved to the left by actuation of same result would be accomplished where electropneumatic action. is used for this purpose.

In summation it may be stated that the manipulationiof any combination setterbutton such as 16 which produces a releasing oi the resilient contact members carried by a corresponding horizontal=combination slide member and their reengagement to a new series of hooked contact members dependent upon the positioning of the verticalastop slide members existent at that time, wilLinzfact capture the stop combination or tonal characteristics on at that time, and such combination of tonal characteristics may at any subsequent time be reproduced by an actuation of the relay. under control of a combination button functioningto simultaneously energize the entire set of.- ficxible or resilient contactscarried by that particular combination 'slide member.

While the system just described as illustrated in Fig. l, affects all of the stop slide members throughla medium of a single relay actuated by a combination piston the same may be modified to use a double touch piston, or two pistons, to actuate two. relays one of which will cause energizing of one of hook contacts and the other relay causing energization of the second set of hooked contacts, both of the relays being connected to flexible contacts maintained on the same combination slide member. By such modification a combination of stops or tonal characteristics including pedal stops and couplers may be captured or engaged, and by the initial manipulation of the combination piston only the normal stops will be aflected, or on further depression 01' the piston the second relay connected thereto will be energized and the pedal stops or couplers will be affected.

While the structure diagrammatically shown in Fig. 1, described above, is of the type in which the stop-action and combination-action are combined and the stop slider bars'possess the dual function of operating the stop-switch mechanism and the combination setting mechanism, it should be understood that the present invention can be used, irrespective of such combined or dual function. In this latter case the vertical sliding bars shown in Fig. 1, will merely carry the hook contact members alone, and in such modification these bars would be operative by electro-pneumatic means or could be located in the console and be mechanically operated from the stop tablets or knobs themselves. As a matter of fact the present invention could be utilized in a console in which slider bars la, 1b, 1c, of Fig. 1 are mechanically connected and moved by stop knobs or tilting tablets or their equivalent, and the combination slides 12a and 12b of Fig. 1, could be mcchanicallyconnected to the pistons and operated thereby.

Fig. 2 illustrates in greater detail the structural arrangement or location of parts of a combinedstop and combination action, such as has been diagrammatically shown in Fig. 1. In this embodiment a fixed rectangular frame islconstructed of suitablesize tobe placed in the organ chamber, this frame comprising top and bottom members 30 and'31' and side members 132- and 33. An inner rectangular frame member 34 is.

, mounted within the outer iramemember by meansjof a hinge3 1 This inner frame mem ber carries the series of vertical slidingrod members la, lb andlc describedindetail' in'connection with the diagrammatical Fig. 1,- these rods carrying =the1movable contact members of the stop or coupler switches'which cooperate with the f-flxed contacts 3 adjacentthereto when the" slide bars are lifted or'elevated by the pneu i of the fixed frame member and locateddirectly maticmotors 4 carried on the lower member under each slide bar. The inner frame 34 also carries the horizontal combination setting bars 12, 12a, 121 et cetera, these being located atthe top of the frame and having a sliding move ment which is transverse to the movement of j k the stop slide barsi The combination setter-bars 12; 12a, 12b'are operated by pneumatics-13 carried by "the side member 32;ofthe outer fixed frame. It must be seen that when the inner 'frarneis in thposition shownin Fig.-2,fboth the horizontal 'a nd verticalmovable slidebars' are in, operative relationship with the pneumatic motors which controlthem. By unloosening thej fastening means 36,- 36, whichholds the vinner frame in this position the same may be" swung open on the hinge 35 so that convenient! access may-behad tothe entire mechanism of the swinging frame as well asto other-mecha nism such as the co ntrol' chest for the pneumatic 'motors, relays, et cetera, that are'mounted on the inside of the fixed frame and behind themovable frame, thisarrangement of parts, therefore, making a simplefcompact and accessibleconstruction. The vertical slide members 1a, lb, 10,, et cetera, carry at their' upper-ends the hooked contact members which cooperate with theresilient contactmembers carried on'the horizontal combination -sliderbars in the manner previously described in connection with Fig. 1.

Figs. 3, 4 5, and fi illustrate the invention as appliedto a roller type of switch construction [instead of the sliding bar type. In the front elevation of view Fig. 3 three rocking-'bars' io, 41 and 42 are shown operated by their respec- .tive pneumatic motors 43, 44 and 45. These rocking bars each carry the usual 61 movable contacts which cooperate with contact strips rocker bars 40;41'and42 has projectingfrom its carried onv aboard 4J7 upon whichthe' rocking ba'rs are mounted. For. simplification of the drawings but three sets of'these contacts are illustrated as shown by the reference character i 46. At the right hand end of the devicesh'own iii-Fig. 3,;the supporting -boardj47 fis {provided with three slots 48, 49"an'd 50;, Eachfof the rear resilient contactmembers 51a, 51b and 51b which pass through the slots asshownpin the sectional illustration Fig. 5 whi'ch is: taken on horizontal rear contact strips such as 5211.

It will thereforebegevident that a momentaryactua tion'ofvone of the vertical rotatable. members-54. will act. tovlrelease all of; the resilient contact members which project 'througha slotadjacent 7 that particular roller permitting them to assume the'positions to which they arejbiased at that time. and thenusubsequently capturing them in this position whenthe; rollers 53a, 53bfand 53c areyreturned to their normal locking position. AsshowninFig. 4. each set of: horizontal rear contactuwiresorbars are connected to the onand-ofi-magnets of the. particularstopcontrol devicefwhich controls the stopicontrol member located in" front of the horizontal contact wires.
