My invention relates to improvements in a combination stop action for organs.

One of the objects of this invention is to provide an efiicient and economical combination stop action for a pipe organ, especially adapted for a direct electric organ, whereby the organist can conveniently and speedily set-up, and likewise repeatedly and alternately bring into service, various stopkey combinations, from the organ bench and while playing the organ.

A more particular object of this invention is to provide a mechanism for setting-up organ stopkeys in combination, which comprises improved setter means provided with lock means arranged to eliminate friction between movable parts, preferably by the use of a lock member having flexible or hingedly mounted locking elements thereon, whereby a reduction is effected in the amount of electrical current required for operating the same.

These and various other objects and advantages are attained with this invention, as will become apparent from the following description, taken in connection with the accompanying drawings wherein my invention is shown. in its preferred form, it being understood that various other arrangements and forms of construction may be adopted for carrying out the objects and purposes of this invention.

1936, Serial No. 104,681

This invention briefly pertains to the type of pipe organ provided with several combination pistons, by each of which the organist is enabled to operate a certain group or number of stopkeys simultaneously, without operating each one individually. The master piston is associated with several combination pistons, and it is depressed when the stopkeys desired in a selected combination have been drawn or moved into the on position, and the combination piston is then also pressed whereon said stopkeys are being setup. After thus setting-up the desired stopkeys on the particular combination piston, the two pistons are released, and the drawn stopkeys are returned to their released or off position.

Thereafter, every time this combination piston is pressed, the combination of stopkeys set-up thereon is automatically operated.

My invention is an improvement over such combination stop actions, and in the drawings, by way of example, two stopkeys H and H are shown, being illustrated in connection with one of the combination pistons l2 and the means whereby said stopkeys are set-up on this piston, to be operated thereby.

Other combination pistons as indicated at l2a, are similarly arranged and adapted to have a group of stopkeys set-up thereon.

The stopkeys I I and l l are provided with actuating units l4 and I4, substantially as indicated in Fig. 1 of the drawings. Each of said units includes an off magnet I5 and an on magnet l6 mounted on magnet bar 11. An armature bar I8 is pivotally mounted on bar l'l, extends between said magnets, and carries on its outer end a pair of oppositely extending curved arms l9 and 20, adapted to be attracted by cores 2| and 22 of said magnets l5 and I6, respectively. A rod 23 is pivotally connected to a finger 24 on said armature and to an arm 23 on the stopkey, adapted to move the stopkey to the on or the off position.

These parts are shown in the off position or position of rest in Fig. 1 of the drawings; and the stopkey and armature are also indicated by dotted lines in the on position. The stopkey actuating unit [4 comprises elements like those of the unit l4, being denoted by the same numbers with the prime mark added thereto.

When the stopkey H is drawn or moved from the full line position to the dotted line position of Fig. 1, arm 25 and rod 23 move finger 24, which in turn brings the movable switch contact 21 into engagement with the stationary switch contacts 28 and 29 of this switch unit. Said contact 28 of this switch, and similarly contact 28 of the a switch for stopkey H, are connected with the organ stop circuits 3D and 30, respectively, as indicated in said Fig. 1.

A setter switch unit is provided which is active in setting-up a combination of stopkeys on the piston l2. The unit comprises a magnet 3| which is supported and grounded with its core 32 on a metal bracket 33, and an armature bar 34 extends from the bracket, having a curved arm 35 adapted to be attracted by and movable across said core 32. nected to armature bar 34 and carries movable contacts 5?, 38, 3S, and 39 thereon, cooperating respectively with stationary contacts 41, 42, 43, and G3. The movable contacts 39 and 39 are connected respectively by wires 44, and M with the stationary contacts 29 and 29' of the stopkey actuating units i and I4; and the switch contacts El and 42 are connected by wires 45 and 46 with the stationary contacts 41 and 48 of the combination switch of piston l2, said contacts being engaged by a movable contact 49, and the switch closed upon pressing the piston.

Combination piston l2a is similarly provided with stationary switch contacts 41a and 48a and with a movable contact 49a for closing the switch, and is similarly equipped and connected with a plurality of stop keys adapted to be set-up thereon, as will be understood without duplicating the illustration.

A master piston or toe piston 50 is provided, which is depressed to engage its movable contact 5! with its stationary contact 52. A wire 53 extends from contact 5! to a source of power 54, for example, a generator, from which a wire 55 leads to the bracket 33 of magnet 31, and a wire 56 with a branch 56' connects said wire 55 with magnet bars I? and ll, respectively; while a wire 5'! extends from wire 53 to contact Zl, having a branch 5'. extending to contact 27. A wire 58 leads from contact 52 to the coil winding of said magnet 35. By depressing the toe piston 55 the circuit thru the magnet 3| is completed, current flowing from source of power 54 thru wire 53, contacts 5| and 52, wire 59, magnet 31, bracket 33, and thru wire 55 back to the source of power 54, thereby energizing this magnet to throw these setter switches.

A combination setting and retaining mechanism is furthermore provided, which cooperates with the setter switch unit and is brought into service in setting-up and retaining the stopkeys combined on the piston. This includes a combination switch 5! a switch moving unit SI, and a switch locking unit 62. There is such acombination switch 58 and a switch moving unit 6| provided for each stopkey; while a locking unit 62 is provided for each combination piston 52, and it includes a group of locking elements for cooperation with a group of combination switches, each element cooperating with a combination switch to retain it set.

As best shown in Fig. 3, the combination switch 68 includes an off contact 63 and an on contact 84, also a charge contact 65 extending between the two, and adapted to be brought into engagement with either one thereof. The off contact 63 is connected by a wire 61 with the off magnet l5, and the on contact 64 is connected by a wire 68 with the on magnet l6. Said switch is mounted with suitable insulation on a bar 69 supported on a main frame or frame means 10.

The contact moving unit 6| includes a trace bar i5 having a slot 12, thru which extends a screw '53 arising from a supporting bar 14 which A main bar 39 is pivotally conis supported on frame means it. Said trace bar has openings '15 and 15a, wherethru extend the contacts 65 and 65a of combination switches 68 and Gila, to be moved forwardly and rearwardly into the on and the off positions. A trace bar magnet 16 is mounted by its core TI on a bracket 78 which is adjustably mounted by a slot and screw means 80 on a metal cross-bar 8!. (See Fig. 4.) An armature 32 is pivoted on bracket l8 and its bent end 83 is attracted by magnet core ll, while a rod 84 on the armature is connected to trace bar ii to move it and the several switch contacts 65, 85a, forwardly from the off position, as shown in Figs. 1 to 5, to the on position as shown in Figs. 6 and '7. A spring 85 is connected to bracket 18 and to armature 82, adapted to return the latter and the trace bar to the off position.

As best shown in Figs. 2 and 3, there are several switch contacts, 65, 65a, in a row, which are moved by said trace bar ii of unit 6!, each one of said contacts and the associated stopkeys being adapted to be set-up on different combination pistons, l2, l2a, etc., so as to be inclusive with stop-keys H and contacts 65 of other rows, in several dififerent combinations.

The switch locking unit 62 includes a lockbar 87 which extends across the several switch moving units 6!, SI, as best shown in Fig. 2 and diagrammatically indicated in Fig. 1. Said. bar has a plurality of notches 88, 88, etc. provided therein, and across the front of each of said notches is mounted a flexible lockbar plate, 89, 89', etc., each plate being swingably mounted on the bar, preferably by a pair of pins 98 secured on the bar and extending thru enlarged openings provided in the plate, whereby the plate is hingedly or swingably mounted on the bar, forwardly o the opening, and is adapted to yield when a s-.-. a contact 65 is drawn forwardly thru the notch 83 toward its locking position. The i mounted on a shaft 9! being positioned forwardly thereof, and said shaft is rotatably supported on brackets 92 which are adjustably mounted on frame means 10, by slot and screw means 92, for example, as indicated in Fig. 2.

This flexible and swingable arrangement of the locking plates enables each one of the plates 89, 8%, etc., in a row to yield readily when the trace bar H is drawn forwardly by magnet l5 pulling the row of contacts 65, 65a, etc., against said plates, while moving into the on position. The particular plate 89, by operation of its lockbar Bl, can then be readily drawn upward or raised above the particular switch contact 65 of the selected combination, as indicated in Fig. '1, without creating any appreciable friction, to be thereafter dropped back of said contact, as shown in Fig. 6.

This locking unit 52 is operated by a lock bar magnet 93 which is mounted with its core 94 on a bracket 95 secured on a bar 96 supported on frame means 10, while the armature bar 9"! is pivoted on the bracket 95 and has a bent end 98 movable across the magnet core A rod 99 is pivotally connected to the armature bar and to an arm I06 arising from the shaft 9|, whereby said shaft is rotate when the magnet is energized. A spring I96 is connected to said armature bar 91 and to a plate 162 which is adjust-ably mounted by slot and screw means U33 upon bar 96 on frame means 70, thus providing for adjusting the tension of the spring. The lockbar 8'! is thereby automatically returned to its off position when magnet 93 is de-energized, and a stop bracket N14 with suitable cushioning means limits Cir K said contacts.

the movement of armature bar 91 to the off position.

It should be noted that in this illustrated construction the electromagnets have their negative lines connected to the steel frame of the mechanism, since the coil winding of each magnet is grounded on the core, and the core is mounted on the steel frame. This arrangement requires only one wire extending from each coil, as indicated in the drawings, and it eliminates the necessity of running a second wire to each coil.

The trace bar moving magnet '16 has its coil winding connected by a wire I05 to contact 43 of the setter switch unit; and magnet I6 is similarly connected by a Wire I05 with the switch contact 43'. A wire I55 connects the metal cross 8| electrically with wire 55 which leads to the source of power 54.

The locking unit 62 has its magnet supporting bracket 95 connected by a wire ID'I with wire 55 leading to source of power 54. The coil winding of magnet 93 is connected by a wire I08 with contact 38 of the setter switch unit.

The other contact moving units GI are like unit 6|, comprising similar members correspondingly numbered, each unit including the magnet '45 on bracket 18 grounded on said metal cross bar BI, like bracket 16; also including the trace bar II moved by armature 82, as best shown in Figs. 1 and 2.

The other combination switches 60 are like switch 50, each comprising contacts 63 and 64, and the movable contact 65 positioned therebetween and movable by its trace bar 1!. Wires 61 and 68' connect said contacts 63 and 64, respectively, with magnet I5 and I6 of the actuating means of stopkey II.

A combination operating unit H6 is provided which is brought into service when the combination piston i2 is depressed for operating the stop combination on said piston. This operating unit includes an operating magnet III provided with a core I i2 whereby it is mounted on a bracket H3 which is secured on the metal cross bar BI. An armature H4 for said magnet is pivoted on the bracket and its bent end H5 is attracted by the magnet core II2.

These operating magnets I I I are mounted with their brackets M3 on metal cross bar 8|, below the trace bar moving magnets I6 with their brackets 1'8, both sets of magnets being grounded on said bar, substantially as indicated in the drawings.

As best shown in Figs. 5 and 6, this unit III] also includes a roller H6 which is swingably mounted in brackets IIl supported by frame means I0, and it has a metal contact strip II 8 extending longitudinally thereof and projecting from its periphery, adapted to establish contact with the several movable charge contacts 65, 65, when the roller is swung. A rod H9 is pivotally connected to an arm I on roller H6 and to an arm I2I on armature I I4, for swinging the roller to establish the contact between said strip and A spring I22 is connected to bracket and to armature Ii l, for returning the latter to the off position. A contact blade I23 is supported by means I24 on frame means In and is adapted to make contact with said metal strip H8, and a wire I25 leads from said blade to the wire 53 which is connected to the contact 5| oi the toe piston; while a wire I26 extends from the coil winding of magnet III to the contact 4! of the setter switch unit.

Further mechanisms are provided, of course,

for setting-up and bringing into service different groups of stopkey combinations on other combination pistons, which are operatively connected with the master piston. This is indicated in the drawings, by piston I2a with its switch contacts 41a, 48a, and 4 911, the latter being shown connected with the wire 53 extending from the master switch. It is further indicated by the combination switch 65a with its contact 63a, 64a, and 65a; also by the trace bar locking unit 62a with its lockbar 81a, shaft 9Ia, magnet 93a, and rod 99a connecting the armature 91a with arm IOIla on said shaft am, the roller H60, and its contact strip II8a being adapted to engage contacts 55a, the same as disclosed above.

The operation. of the disclosed mechanism is as follows The various elements and parts of the mechanism are normally in the off position or position of rest, as indicated in Figs. 1 to 5 of the drawings, but some of the stopkeys may be in their drawn or depressed position.

In order to place all depressed stopkeys associated with the combination piston I2 into the off position, the piston is pressed making contact between elements 49 and 41, whereupon the current passes from source 54 through wire 53, contacts 49 and ti, wire 45, contacts 31 and M, wire I26, magnet III, bracket II3, metal bar 8I, wire I06, and wire 55 back to the source 54, there by energizes said magnet and swinging strip H8 into engagement with contact 65; whereupon the current flows from the source 54 to wire 53, wire I25, contact element I23, strip II8, contact 55 and63, wire 61, magnet I5, bracket i1, wire 56, and thru wire 55 back to source 54. The energized magnet I5 thereby draws its armature I9 and stopkeys II into the released or off position.

The combination of stopkeys can then be set-up on the piston. This operation involves the following steps:

First.Draw or press down the particular stopkeys which are desired to be included in the combination on the piston I2. This brings the stopkeys in the on position and draws the armature from magnet l5 to magnet l6, thereby engaging contact 2! with 28 and 2S.

Sccond.Depress the master piston or too piston and hold it depressed. This engages switch contact 5I with 52, closes the circuit thru wire 53, magnet 3!, bracket 35, wire 55, source of power 54, wire 53, and thru said contacts, thereby energizing magnet 5i and moving switch bar separating contact 31 from 4|, and engaging switch contact 38 with 42, 39 with 43, and 39 with 43'. This completes the trace bar magnet circuit, from source 54 thru wire 53, wire 51, contacts 2? and 25, wire 44, contacts 39 and 43, wire I65, magnet 76, bracket 18, metal bar BI, wire I06, and thru wire 55 back to source 54. The switch 31, 4| being open, the circuit thru the combination operating magnet I I i will be broken, thus rendering said magnet inoperative during the setting-up operation.

The energized magnet l5 actuates its armature 82 and draws trace bar Ii forward thereby drawing the associated contacts 65, a forwardly thru the notches 88, 88a, against the lockbar plates 88, 89a, and as said plates are flexible and swingable they will yield to enable such movements of these contacts. The contact 35, which is to be included in this combination, is thereby moved against the companion contact 64, to close the circuit thru this combination switch to its on magnet 16.

Third-Press the combination piston l2. This engages switch contact 9 with contacts 41 and it, and current flows from source 54 thru wire 53, contacts t5 and 48, wire it, contacts 42 and 38, wire E88, magnet bracket 95, wire I01, and thru wire 55 back to the source 54; thereby energizirr magnet and drawing its armature S? and the rod 529 to wing shaft 95 and raise the lockbar 8i and therewith the lock plates 89. This enables the raised lock plates 89, which have been fi forwardly by the forwardly drawn contacts that are associated with the depressed stopkeys, to pass over said contacts to the rear thereof.

Fourth.Rele-ase the combination piston I2, thereby breaking the circuit thru the locking magnets whereupon the lockbar 8'! with its lock plates 83 drops back of the selected contacts to retain them in the on position, as indicated in Fig. 6.

Fifih. Release the toe piston or master piston thereby separating switch contacts 5! and and breaking the circuit thru magnet 3i, whereupon switch bar 36 moves to its initial position, thereby again connecting switch contacts 3i and again separating switch contact from 39 from and 35' from 43'. This again completes the broken path betwee the source of power 55 and the operating magnet.

Sixtir.Upon presssing combination piston l2, for bringing into service the stopkey combination set-up thereon, the current passes from source of power 5 thru wire contacts 39 and wire 5 contacts and wire magnet Hi, bracket H3, bar 85, wire i533, and thru wire 55 back to the source of power 54; thereby energizing magnet Hi and operating its armature i and the connected rod iii), to swing roller and make contact between its strip H8 and the locked contacts etc., as well as with contact member i This closes the circuit from source of power thru wire 53, wire i252, contact member E23, strip H8, contacts 55 and wire on magnet i8, magnet bar b0. i'?, wire 53, and thru wire 55 back to the source of power thereby swinging the armature to the on magnet 55 and moving the stopkey into its depressed or on position. The depressing of the combination piston thus brings all the stopkeys that a set-up in combination on this pisteinto the des ed service position.

To iree the stopizeys from the combination in which they have L set-up, proceed as follows: First.-Place s a stopkeys in their raised or release position, in Fig. l.

During this operation the trace bar magnet '16 is not energized to draw the trace bar H into locking position, since the circuit of this magnet is open, as contacts 29 and 28 are separated, as shown in Fig. 1.

While I have disclosed certain preferred embodiments of my invention, these are to be taken as illustrative only, as it is capable of change and variation to meet diifering conditions and requirements, and I contemplate such modifications as come within the spirit and scope of the appended claims.
