Figure 9 is a perspective View showing a magnetic record which may be used in conjunction with a suitable magnetic pick-up for impressing the recorded vibrations upon a sound reproducing and device actuating system in accordance with the present invention; and

Figure 10 shows a modified arrangement of a part of the system illustrated in Figure 1.

To illustrate the invention, there is shown on Athe drawings, in Figure 1, an electrical system for reproducing sound and, at the same time, controlling operable devices, such as a tuned relay 2|, from a record represented generally at II, through a pick-up device I5. The sound record II may be made in any suitable or convenient manner known to the art and maybe of any suitable form, that is to say, may be a groove formed in a` cylinder or disk, las shown in Figure 41; may be a photographic record on fllm, as shown in Figure 2; or may be a magnetic record formed, as for instance, in an iron wire as shown in Figure 9.

As shown in Figure 3 the record II consists of a single recorded track incorporating both a normal sound recording I2, which, for simplicity, shall be called the sound track, and a deviceoperating recording I3, which shall be called the operating component; that is to say, the normal sound track is combined with the operating component so that the record II consists, in part, of recorded vibrations I4, comprising the resultant of the sound track I2, and the operating component I3.

The operating component I3 may have a sinusoidal wave form as shown in Figure 3, or may be of more complicated configuration. The wave may be a simple wave or may be the envelope of an oscillation of higher frequency. The wave may have uniform frequency or may be a coded series of vibrations, in which case, the relay 2| is a coded relay adjusted to react only to the particular coded component in response to which it is desired to have the relay react. g v

The operating component moreover need not necessarily be artifically applied to the record, or the original sound, but may be a pre-selected component of the sound sequence itself, the relay 2I being adjusted tore-act to the particular selected component, as for instance, in orchestral music, the relay may be set to operate in response to a particular note of -a particular instrument.

'I'he recordi'll, if the operating component is applied thereto artificially, may be prepared in any suitable manner as by'connecting, with a suitable recording apparatus I 4 I, a suitable device |43 for delivering to the recordingy apparatus the operating component at the proper' time so that the same may be superposed upon the sound vibrations as they are recorded, the sound vibrations being fed into the sound recording device by any suitable pick-up, such as a microphone |45, if the record is made from the original sound, or a pick-up device |46, where the record II is made from a previously recorded sound` track, or a microphone and pick-up may be used together if aoeaoie desired as where previously recorded incidental music is to be fdubbed as a background in the ator whenever it is desired to impress the operating component upon the sound recording. This is known as dubbing the operating component on the sound track.

Alternatively, a device |48 is capable of creating vibra'tions in the air, may be positioned near the sound pick-up |45 of the recording device |4|, the vibration device being actuated at photographic records.

intervals to add the desired operating component tcpthe sound waves reaching the pick-up device.

Numerous other methods of superposing the operating frequency upon thesound track in the record fwill suggest themselves to those familiar with the art of recording sound waves and the invention is not necessarily limited to any particular mode of producing the composite record It is, however, preferable to prepare the composite record by -dubbing the operating frequency upon the sound track, rather than by adding the same to the sound waves before they are applied to the pick-up |45.

The foregoing methods Vmay be employed in making record grooves in wax or similar material, and in making magnetized wire records and It is also contemplated making magnetized wire and photographic records by first applying the actuating component Aupon the recorded sound track. In case of the magnetic record, this may be accomplished by magnetizing thewire at the proper places in accordance with the desiredoperating component, the wire being either previously or subsequently treated to magnetize it in accordance with the V sound track recording. l

In photographic records, the operating component may be photographed on the undeveloped' negative on which the sound track record is subsequently or has previously been photographed, and the double exposure developed on the negative from which a positive print of the composite recording can be made, or a negative of a normal sound track-record may be printed as a. positive andthe print of a separate negative of the operating component superimposed on the positive print ofthe sound sequence and the double exposure developed on lthe positive.

The sound-reproducing and device-actuating system consists of a suitable pick-up device |5 adapted to be vibrated in accordance with the vibrations recorded on the record a sound-emitting device or loud speaker |9 connected to the pick-up preferably through the amplifying system |1, and a tuned relay 2| adapted to be actulated by the operating component of the record and also connected with a pick-up device through a relay operating system 23 and filter 25.

The pick-up device I5, as shown in Figure 1 of the drawings, may consist of an ordinary magnetic device, such as'is `commonly used in conjunction with the ordinary groovedV phonograph record, or, an ordinary mechanical phonograph pick-up may be used in conjunction -with a microphone to impress the vibrations of the record uponthe input of the amplifyingsystem |1.

In Figure 2 of the drawings, the sound track is shown as a photographic record, such as is commonly used in the audible moving picture art and the pick-up device includes the light source 29, the aperture 3| and atarget 33, comprising a'photo-elec'triccell, or other'light-sensitive device, connected to the input of the reproducing. system and upon'whichlight rays from 'the light source impinge after passing through the aperture and the photographic record |I,"as is Well known in the art.

The invention does not necessarily reside in the particular form of record and co-operating pickup device employed by any suitable or convenient form or forms of record and cooperating pick-up device may be used to apply the vibrations of the record upon the sound reproducing and deviceactuating system. z

Similarly, the amplifying system I1 may. be of any suitable or convenient form or arrangement for the purpose of receiving the vibrations initiated therein by the pick-up device of whatever character used, amplifying Vthe vibrations and delivering the amplified vibrations to the sound-emitting speaker I9 and to the relay2l. In some cases, it may be possible to omit Ythe amplifying system, entirely, but ordinarily some form of amplification is desirable. y

To illustrate the invention, therefore, there has been shown an amplifying system comprising a transformer 35, the primaryl winding 31 of which is provided for connection with' the pick-up and thus forms the input of .the system andthe secn ondary winding 39 of which is connected through a variable resistancevolume control arranged as a potentiometer 4| to a vacuum tube 43, the grid 45 of which is connected with the shiftable member-of the potentiometer 4|, the plate 41 of the vacuum tube 43 being Ivconnected to one end of the primary winding 49,` of a transformer 5|, the other end of the primary winding being connected through a condenser 53, to one side of the filament 55 of the vacuum tube, said side of the filament being also connected through 'the lgrid bias means,preferably an electric battery 51,

with the potentiomter 4|. Thelament 55 may be heated in any convenient manner as is well known in the art and terminals 59 and 60 are provided for supplying the plate potential. One

end of the secondary winding 53 of the trans-` former 5| is connected with the grid 65 of a vacuum tube 51, the plate 69 of which is connected to one end.of the primary winding 1| of a transformer 13, the secondary winding 15 of whichl comprises the output of the amplifying. system I1. The lament11 of the vacuum valve 61 may be heated in any suitable or convenient manner and one side of the filament is connected through the grid bias means, preferably an electric bat-` tery 19, with the secondary winding 53 of the.

transformer 5|, the same side of the lament 11 being connected through the condenser 8| withthe primary winding I1| of thev transformer 13.

Terminals 83 and 85 are provided for supplying the plate potential. k

, The speaker I9 is connected byA means of suitable conductors 89 to the winding 15, the re.- lay 2| being connected, through the relay-operating system 23 and the filter 25, to the winding 31.

The ilter 25 comprises inductance,` coils 9| and condensers 93 and forms a filter tuned to the frequency Vof the operating component of the record V| so as to pass the operating component freelyfwhilek attentuating and suppressing other frequencies.

The input of the filter may be connected with' the'output winding 15 of thel amplifying system |1, or may, as shown,vbe connected to the secondary 92 of a transformer 94, the primary 98 of which forms a part of the .primary circuit of the transformer 35. This has the advantage that the relay is not subjected to the volume control 4| of the amplifier as is the case where the relay is actuated from the output of the amplifier Il. The output of the filter 25 is connected to the input of the relay-operating system 23 which comprises means to` amplify the operating component and includes a transformer 95, the primary 91 of which forms the input of the system and the secondary 99 of which is connectedv at one end to the grid |0| of a vacuum tube |03l and the other end of which is connected through a grid-biasing. means, preferably an electrical battery |05, with one side of the lament |01. The filament |01 may be heated by any suitable or convenient means well known in the artA and terminals ||5 and ||1 are provided for applying the plate potential between the plate and filament.

'I'he coil I9 of the tuned relay is connected across the output of the amplifier 23. The relay 2| is adapted for operation by alternating currents delivered to the coil, the function of the relay-operating system. 23 being to amplify the po'wer of the relay-operating component sufciently to operate the relay, which may require for its operation more power than is delivered to the operating system. In some cases, it may be satisfactory to eliminate the system 23 and v0perate the relay directly from the pick-'up or from the output of the system The relay, when l actuated by the operating component, operates the shiftable member |09, which may be mechanically connected to control a device to be operated, or, as illustrated, may be arranged to operate an electrlcalswitch for controlling the circuit ||0,` which, in turn, may be connected to effect the electrical control of any device to be operated.

While in some cases it not be necessary i tc utilize the amplifier 23 and the filter 25, since it is possible to operate the relay 2 I' directly from the output of the amplifier system Il, it is, however, desirable to provide these' refinements -in order to insurepositive operation of the `relay in response to the operating component on the record. v

Any desired number of relays 2|'may be connected in parallel and actuated from the out-- spond. Such band pass filters may be of construction similar to the filter 25.

If each relay is connected to the -bus connecters through the intermediary of a filter, each lter may be selected or adjusted to pass a particular frequency. so that by forming operating'components I3 at different frequencies in the record, the several relays so connected may be caused to operate selectively. The arrangement will be more fully discussed in connection with Figure 7. Moreover, if. the relay is connected through a -lter 25 and an amplifier 23,-the relay itself need to obtain selective operation of the relays, the

filter, which is preferably used in the combination, being a low-pass filter to pass all frequencies within the tuned range of the relays.

If. the operating component has a frequency within the range of audible frequencies, the speaker or sound-emitting device I9 will, of course, respond to the audible frequency of the operating component whenever the same is impressed upon the system by the pick-up device.

It is possible to utilize a speaker I9, which will react only to a certain band of frequencies within the audible range and for all ordinary purposes, it is quite practical to use a speaker operating in the audible range of frequenciesv above 80 cycles and below 5,000 cycles since a speaker in this range will accurately reproduce all normal speech and music and it is contemplated using such a band frequency speaker and to maintain the operating components at frequencies below 80 cycles and above 5,000 cycles, even though frequencies as low as 40 cycles and as high as 10,000

ponent as sound may be undesirable where the' sound sequence is being reproduced for its pleasing effect upon the hearer, it has been provided to eliminate the transmission of any sound by the device I9, which maybe caused by the operating component.

This may be accomplished by causing the re- .i

lays 2| to switchlsuitable flltercircuits into operation in the speaker circuit so as to silence the speaker circuit to the operating frequencies only.

It is preferred, however, to filter the operating 'component from the circuit 89, leading to the speaker, by inserting in the conductors 89, be-

-. tween the output of the amplifying system |1 and the sound-emitting device I9, a band-eliminating filter 90, which functions to highly attenuate the frequencies of the operating components of the record.

In Figures 5, 6 and 7, there are illustrated systems whereby the record may be utilized to control a progressively operable device, such as A the selector switch illustrated in Figure 8, during the progress of the reproduction of the record and whereby the selector switch may be automatically turned to a predetermined setting from -any switch position, as for instance, where it may be desired to turn the selector switch to an initial or starting position at the'termination of the reproduction of the `record in. order tobe ready for the next time the record is reproduced or played.

. As shown in Figure 8 of the drawings, the selector switch comprises a frame |5| carrying a rotary element |53 lcomprising a blade 155,. the opposite ends of which are adapted to lextend from the rotary support |53 in diametrically pposite airecti'ons'-y 'rne ends of the blade lss terminate in contact portions |51, |58, adapted when the blade is rotated on the frame to progressively engage the blade contacting portions of a set of terminals |59, which are carried on an insulated support frame |6| mounted on the ma'n frame |5I. The contractor |51 engages the terminals |59 in succession during one half turn of the blade |55 while the contacter |58 repeats the terminal-engaging' process during another half turn'of the blade. Each one of thel terminals |59 may be connected to form parts of external control circuits adapted to be actuated when the blades engage the terminals |59. The'set of terminals |59 and its co-operating contactors may be multipled to any desired degree, that is to say, the rotary switch may include a plurality of terminal sets and `co-operating switch blades, sets being mounted adjacently on the frame I5| and the co-operating blades being mounted adjacently on the rotary element |53.4

In the embodiment shown in Figures 5, 6 and 7 of thedrawings, asis also the case in Figure 1, the pick-up device I5 is connected in series with the input windings 31 of .the amplifying'system` I1 and 96 of the relay-actuating sys- 4tem which comprises the transformerl 94 and iilter 25 and the amplifier 23 so that thesound track I2 4of record |I may operate the loud speaker I9 through vthe amplier |1 .while the operating'components I3 may actuate the relay y2| as previously described in connection with the system shown in Figure 1.

In Figures 5, V6 and 7 also'the rotary selector switch is shown diagrammatically and we haveA illustrated, in each case, two sets of terminals |59 and terminal engaging blades |55, but lit should be understood that any desired number of terminal sets may be used in order to multiply the control circuits actuated by the rotary switch.v The rotary switch also includes a relay having a solenoid |63 `mounted on the frame |5| and an armature |65 tiltably mounted on the frame adjacent the solenoid and adapted to be shifted against the base of a spring |61 whenever the solenoid |63 is energized.r A switch |69 also is carried on themain frame of. the rotary switch and vis operatively associated with the amature |65 so as tobe opened whenever the solenoid is energized. `I'he armature |65 carriesa pawl |1| .extending `to a ratchet wheel |13 which is fixed to the rotatable element |532 The pawl I"|,I is normallyurged` by means vof the spring |15 into engagement with the ratchet wheel sothat aslthe armature is tilted Aon thel frame |5| by'the valternate eiect of the spring |61 and the energized solenoid |63', the'pawl may cooperate with the ratchet ',wheel to pro-l gressively rotate the element |53 and thus advance the switch arms |55 into progressive contact with the terminals |59. A' detent |16 also is mounted on the frame in position to `co-operate with the ratchet wheel to permit it to be advanced in' one -direction lonly, by the pawl |1I.

- The selector switch illustrated is' a typecommonly usedin telephone circuits and has -been shown here byway of explanation ratherthan by limitatiomsince it will be obvious that the invention is not limited to any particular form o'ir switch and,.in i'act, may apply to 'any progressively-actuated device.

ated device to be controlled is shown diagrammatically as a rotary switch of thel type illustrated in Figure 8 and including at 1east`tw0# The progressively-actul sets |11 and |19 or terminals |59 and co-operating contactors. The terminals |59 of the set |19 are provided with conductors |8| whereby 1 the same may be connected in .external control circuits while means is provided to connect the contactors |51 and |58 of the set |19 with an external conductor |83 whereby to complete the external circuits in the arrangement shown in Figure 5, one end ofthe coil of the solenoid |63 is connected in series with a 4contact switch |85,

the other side of which is connected in series through a source of electrical power |81, and thence to .the other end of the solenoid coil. The switch |85 is actuated by a time-delay relay |89, and is closed after a predetermined timedelay when the solenoid or the relay is energized.`

The solenoid |89 is arranged in a series circuit including a power source |9I, and the switch |09 of a system similar to thatshown in Figure 1.

With such an arrangement, the relay switch |09 will close every time an operating component .I3 energizes the pick-up and therelay |89 will consequently close the switch |85 and complete a circuit for energizing the solenoid |63. It is, of

course, possible to dispense with the time-delay relay |89- by connectin'gthe switch |09 directly in the operatingA circuit of the solenoid |63 in place of the 'switch |85 but it is preferred to use a time-delay relay'to eliminate operation of the operating circuit when the switch |09 is ,closed accidentally for an instant, as sometimes happens as a result of influences exerted upon the system other than' the definite operating frequencles I3.

When the solenoid |63 is energized by the closure y of the Switch |85, the armature |65 in the illustrated embodiment will tilt 'in a clockwise direction about its pivot point against the tersion -of the springV |61, the'pawl I1| being car-- ried downwardly, As soon as the operating frequency ends, the switchesl |09 and |85 open, thus breaking the* solenoid circuit and permitting the spring |61 to draw the armature 'in la counter clockwise'dlrectlon thus raising the pawl and advancing the ratchet wheel |13 sufficiently to turn the contacts |55 into engagement with the next adjacent terminal |59.

The operating system just Adescribed for the- `selector switchv is in .itself novel and when used with the record canl be'utilized to effect the con- 'trol of the external-operating circuits |8I-|83,

and thus'control any desired series of operations.

After the record has been reproduced, the se- I lector switch, depending upon the number of op- :v

erating componen-ts I3'contained -in 'the record, will have advanced vto a position engaging one \of the intermediatecontacts |59 of .the set |19,

' turned to a position in' which the contactor |55- this end the terminals of the set |11 with the exception of the end terminal |60 are connected in series.

A switch |95 is also provided and this switch is adapted to be closed whenever the pick-up device is conditioned to commence the reproduction of the record.

In the illustrated embodiment, the record II is in the form of a disk and the pick-up device is carried on an arm 20| swingably supported to move across the disk record while the switch I95 is operatively connected with the arm 20| in such a way that whenever the arm 20| is moved to raise the pick-up device .from the record, ,the switch |95 will be closed. 'I'he switch |95 is connected in a series circuit including the switch |69, the power source |81, the contacts of the set |11, and the solenoid |63. The shorted contacts of the set |11 being connected to one end of the solenoid coil |63 and the contactors |51 and |58 being connected to the switch |95' which is connected through the switch |69, and

the power source to the other end of the coil |63 so that when the arm 20| is raised in order to either reset the device I5 to a position for starting the reproduction of the record, `or to enable the record to be removed from its turntable, the switch I 95 will be closed. This will complete a circuit through the solenoid |63, and the amature |65 will be actuated to turn the ratchet wheel. Instead of moving only once to advance the contactor |55 to the next adjacent terminal |59, as in the case where the switch is operated by the operating frequency I3 in the i record, the switch ,|95 is held in closed position but the armature, in moving downwardly, 'under the influence of the spring |61, will permit the switch |69 to close and re-establish the circuit through the solenoid |63. Consequently, the armature will again be turned in a counterclockwise direction and will continue to make and break the circuit at the switch |69 and reciprocate the pawl |1I until the ratchet wheel |13 is of the set I 11 reaches the terminal contact |60 at which time, the solenoid circuit will be'broken because the terminal is not connected in the circuit as are the other terminals of the set |11.

Obviously the switch |95 does not necessarilyv have to be mounted for operation by the movement of the arm 20| but .may ,be actuated in any other suitable way as, for instance, by forming the switch as a .push button for'manual operation in response to the movement of a switch Vused to control the driving means, which shifts the record pass the pick-up device I5. It is also possible tov provide for shifting the switch arm I 55 to any desired position at any time by isolating one of the terminals of the set I 11 to thus cause the arm |55 to stop opposite said isolated terminal.v Othercontrol circuits for setting the switch arm to a predetermined position will suggest themselves to those skilled in the art whereby, should the switch arm |55 be shifted or held from shifting in order to synthe rotary switch with the record in order to bring the switch into step, should it for some reason or other get out of step with the record during the playing of the same.

rI'he system illustrated in Figure 6 of the drawings is ,adapted to utilize a plurality of operating frequency impulses in order to set the switch arm |55 to a desired position. The operating frequency impulses are formed as a Asuccession of impulses, which are impressed on the record at the conclusion of the recorded sound frequency or sensory eifect as indicated at I3' in Figure 6 of the drawings. The switch |85 in this system is connected in series with the power source |81, the solenoid coil |63 and theterminal set |11, all of the terminals of which set are connected together with the exception of the terminal |62, which, in .the illustrated embodiment, is next adjacent the nal terminal of the set but which, if desired, may be any of the terminals of the set opposite which it is desired to stop the arm |55. A switch |96 is also provided and this switch is adapted to be closed just before the reproductionof the record commences. switch may be arranged for voperationin 'any suitable or convenient manner andi may be formed as a manually operable push button, or for operation by the starter switch that controls the mechanism for moving the record past the pick-up device but it is preferred to form the switch as illustrated so that the same is closed momentarily when the arm 20| is positioned to engage the pick-up'device I5 with the initial portion of 'the record in commencing the reproduction' thereof. The switch |96 is connected in series with the power source |81 and the solenoid |63, As the record is reproduced, this solenoid I63.will be periodically actuated by the operating frequencies I3 of the record, the actuation taking placey through the system including the transformer 94, the lter 25, the amplifier 23 and the tuned 'relay 2| and the timedelay relay |69. Consequently, the switch arm |55 will be progressively advanced and atv the conclusion of the record will occupy a position oppositev one of the intermediate terminals |59. At the end of the record, the series of operating frequencies I3 will cause the switch to be rapidly advanced, there being enough impulses to ensure that the arm' |55 is carried into position opposite the free terminal |62, at which point movement of the arm in response to the energization of the relaying will stop because the terminal |62 is. not connected in the circuit including the switch |65 closed by said relay. 'I'he switch arm will remain in such position until y the switch v|96 isclosed, at which instance, the

the solenoid |63 is energized by the rst operat- I ing frequency |3 of the record, it will be moved into engagement with the terminal |59 that is connected to the rst of the external circuits |8| to be actuated. It will be noted that the succession of operating frequencies I3 is utilized vto move the arm |55\to a position just short of the initial position after which the switch |96 is actuatedto bring the switch arm into the initial position. In Figure 5, on the contrary, the actuation of the switch |95 is utilized to bring the switch arm |55 directly to the initial position. J f

In Figure 7 of the drawings, there has been illustrateda system where a single operating frequency,..at the termination of the record, is used in place of the series of impulses I3 to turn that employed in the operating frequencies |3.

In the system shown in Figure '7, the contacts |59 of the series |11 are, with the exception of the initial and final terminals |60, connected together and the so-connected terminals are connected in a series circuit including the switch |69, aswitch 203, .the power source |81', and the coil |63, the interconnected terminals being connected to one contact of the switch |69, the other contact of the switch being vconnected to 'one terminal of the switch 203, the other terminal of said switch being connected to the power source |81, the other side of the power source being connected to one end of the coil |63, the other end of which is connected to the'contactors of the terminal set |11. The coil |63 and power source |81 are also connected in series with the switch |85 so that the switch |85 operates in parallel with the switch 203 and the inter-connected contacts of the set |11 upon the coil |63 and the power source |81 so that'either closure of the switch |85, or closure of the switch 203 with one of the contactors |51, |58 engaging one of the inter-connected terminals, will energize the coil |63. 'I'he switch 203 is of the toggle type, that is to say, is provided with yielding means 205 which operate to hold the switch in either open or closed position. The switch |85, however, is normally urged by Vmeans of the spring |86 toward open position so that the"swi tch is opened by the spring |86 except when the relay coil |89 is energized. Interlocking means 201 is also preferably provided between the switches 203 and |85 so that, when the switch |85 closes, the switch 203 will be opened. The switch 203'may be closed by means of the solenoid 209 which may be connected directly to the output of the ampliiying syst'em 23 or maybe connected to the output of the system through an'intermediate relay similar to the relay 2| andpower source similar 4tothe power source |9| employed in connecting the relay I89 to the output of the amplifying system 23. The relay |89 is connected in series with a power source |9| anda switch |09, which switch is operated by the coil I|9 of the relay 2|, said coil I|9 being 4connected to the output of the amplifying system 23. 'I'his system is adapted for turning the switch arm |55 to a predetermined setting' vsuch as the initial or starting position when .a

single operating frequency I3" occurs in the record, said operating" frequency I3" having a different wave characteristic or frequency from that of the operating frequencies I3.l The relay 209 is responsive only to the operating frequency I3" While the relay |89, through relay 2|,-is responsive only to the operating frequencies I3.l Consequently, as the record moves past the piclt-l updevice I5, the relay coil |89 will be energized` v each time'the pick-up device encounters one of the operating frequencies I3, the coil |09 remaining inactive.

It will be noted that should lthe switch 203 be closed, when theirst operating frequency I3 energizesthe relay I 89, the closure of the switch -will open the switch 203. Each time the solenoid |83 is yenergized by the-closure of the switch |85 in response to an operating frequency I3, the pawl |1| Willadvance the ratchet |13 at a distance suiiicient to move the contacts |51 fromterminal |59 to the next adjacent terminal |59. 'Thus as the record progresses, the various circuits r |8| will be actuated successively. At the concluv sion of the record, the arm |55 will have advanced to a position intermediate the end positions.

The final or switch-setting frequency I3" will' will remain'closed until opened by the actuation` of the relay |89 in response to a later operating frequency |3. As the switch 203 closes with the contactors |51 engaging one of the interconnected terminals |59 of the set |11, the coil |63 will be energized to turn the ratchet wheel |13. As the armature |65 moves to accomplish this, the switch |69 is caused to open and break the circuit, deenergizing the coil |63 and permitting the armature |65 to return to its normal position under the iniluence of the spring |61, thus reclosing the switch |69 and again energizing the relay s o that as long as the switch 203 remains closed and the contactar |51 engages one of the intermediate terminals |59 of the set |11, the arm |55 will coniinue to advance. As soon as the contactor |51 reaches the isolated contact |60 of the terminal set |11, the circuit, includingthe switchl 203 and,

the switch |69 will be opened and thel coil cannot thereafter be energized through said circuit to advance the switch arm |55. It will be noted that by simply isolating the terminal |59 of the set |11 at the desired stopping point. As the recordv continues to play, or if the record is repeated, the

Obviously the switch` rst operating component I3 to engage the pickup device will energize the coil |89, will open the switch 203 rand will advance the switch arm |55 into position engaging the contactor |58 with the first terminal |59 next adjacent to the isolated terminal |60.

As an alternative arrangement, the switch203 may be formed simply as a normally open switch similar to the switch |85 instead of as a toggle vswitch as shown, and the interconnecting arm 201 omitted. With such an arrangement, the devicesetting recording I3 may be extended' so that the coded frequency initiated in the relay 209, when the pick-up device I5 engages the recording I3", will be continued for an appreciable period vand will hold the switch 203 in closed position maintainingl the switch circuit in operation long enough to permit the contactor arm- |55 to be advanced to the desired position.

It should be understood that the relay parts |63, |65, and I69'operate extremely rapidly when the switch 203 is closed to turn the arm |55 so that the resetting impulse initiated in the system by the device-resetting recording I3" is not necessarily unduly prolonged, in fact,l the effect produced by the recording I3" on the pickup in the modiiied arrangement need only prevail for a few seconds.

Itis also desired to" direct attention to the possibility of utilizing the invention in the control of a system incorporating the so-called telegraph relays, which respond lto coded vibrations initiated in the system, that is to say, each relay may be calibrated to respond only to a` definite sequence ofl relatively long and short impulses, or torrelatively long .and short gaps between impulses.

Relays of this character may be incorporated in the device-operating system in place of the relay 2| and the device-operating recordings I3 formed in the record in such a wayas to provide a coded series of relay-operating impulses upon the system so that any desired one of the calibrated relays will respond to its proper coded impulse initiated by the coded vibrations on the record.

The present invention has many practical applications. It may be incorporated with a picture-displaydeviceln order to deliver fa lecture or suitable music', and, at the J'same time, cause the picture displayed by the device to change at the proper time during the lecture or accompanying music. This is accomplished simply by having the picture-changing mechanism actuated by the relay 2l, that isto say, whenever the operating component occurs in the record Il, the picture will be changed.

The picture-display device may be of any type, for instance, the ordinary automatic stereopticon or slide projector comprising devices for presenting a series of slides or pictures in position for display, or may be a still-film projector, that is to say, a device employing cinematograph lm having pictures photographed in the successive frames of the iilm and mechanism for advancing one frame at a time and allowing each picture frame to remain in display position until the picture-changing mechanism is again actuated to advance the next frame into displaying position.

'Ihe'apparatus and method of our invention may also be used in art museums to actuate picture-illurninating means in conjunction with the reproduction of a lecture concerning the pictures, which lecture may be delivered or broadcast from a centrally located loud speaker or speakers. The pictures being successively illuminated in order to render them highly visible as they are described during the progress of the lecture.

The invention may also be utilized to Yeffect a practical automatic demonstration of any mechanical device requiring demonstration, as, for instance, in a shop window or elsewhere, in conjunction with th'e delivery of a lecture or explanatory talk, the operation of the demonstrateddevice being controlled through the relay or relays 2l in order to occur at the proper time during the course of the lecture. 'I'he control of the operation of the device being demonstrated and the lectureA both riginate from the pick-up device I5 or its equivalent.

In the projection of talking-moving pictures, it is frequently necessary, in order to obtain dramatic eiects, to dim the lights of the theatre, to vary the volume of sound emitted by the loud speakers, or to control other effect-producing devices at intervals during the visual or picture sequence. Such control operations may be accomplished automatically, by means of our invention, by impressing upon the sound track of the cinematograph illm an operating frequency component at intervals and utilizing this component in accordance with our inventionvheretofore described in order, by meansof the relays 2|, or their equivalent, to actuate a control deviceA for dimming the theatre lights, increasing the amplification of the system through which the sounds are broadcast, or controlling other devices for producing sensory effects during the progress of the picture sequence.

In accomplishing the volume control, it is preferable to utilize suitable switch means for progresslvely increasing or decreasing the ampliilcation in order to eiect the control gradually. With this type of switch, it? preferred to utilize two tion of the picture. y

I-t is also possible to actuate warning signals and perform other control functions such as the starting of auxiliary projectors at intervals during the progress of the talking picture in response to actuating components impressed directly on the sound track and without interrupting the sound or picture sequence. Suchwarning signals may be located .in the managerls oiilce, the box ofce, or at other locations in the theatre in order to advise the manager or the box oflce as to the progress of the picture being displayed. Operating components impressed on the sound track may also be utilized to warn the operator of the projection machine at intervals in order thathe may take proper action to insure the projection of the successive reels at the proper time, that is to say, near the end of the first reel, the sound track may be arranged to give a "make ready warning so that the next reel may be mounted v in a. second machine ready`for projection or may be made ready for mounting in the same machine if only one is used in the theatre, and an operating component may be used to automatically start the second machine in operation at the proper time.

Numerous other useful applications will suggest themselves to those familiar with the practical aspects of the projection of talking pictures in particular and the operation of devices in conjunctionwith the reproduction of sound generally.

It is thought that the invention and numerous of its attendant advantages will be understood from the foregoing description and it is obvious that numerous changes may be made in the form, construction, and arrangement of the several parts without departing from the spirit or scope of our invention, or sacricing any of its attendant advantages, the forms herein described being preferred embodiments for the purpose of illustrating the invention.
