Claims.

The present invention in its more general aspects relates to 'a preference recorder capable of use to provide a permanent record of human reaction to a program. It is particularly advantageous as a mechanism which may be readily installed at practically any location desired, as for example in a home and operated by an individual in the household while listening to a program such as a radio broadcast. The mechanism provides the individual with means which he may adjust continuously as the program progresses in accordance with his degree of like or dislike of the successive events of the program, and these adjustments are recorded as a graph which thereby is representative of his reactions to the successive events of the program associated in accurate timed relation therewith.

As depicted in the particular arrangement hereinafter described, the graph comprises a line produced upon a longitudinally fed strip of thin material, such as a thin acetate film similar in width and having the perforations of a 35 mm. motion picture film, the ordinates or transverse position indicating degree of like or dislike, and the abscissae or longitudinal units representing time, which in turn represent successive events of the program.

The apparatus embodies features whereby, after a record of a particular program is thus made, the record may be readily severed from the continuous roll of strip material and utilized in various ways. According to one particularly useful procedure the operator mails the record into a central office where it is analyzed in connection with other similar records and valuable information and statistics derived.

The apparatus, by reason of its simplified controls and character in general, may be used in its intended manner by inexperienced persons with only a few simple directions.

It embodies principles and features of construction which assure a properly timed relation whereby, in the analysis of the graph produced, the points thereof can be associated accurately with particular moments or events of the program. In addition to the features of internal construction which contribute to such results is the further characteristic that the working apparatus is completely enclosed and unitary in character, and after installation is reasonably free of tampering or disturbance of the timing factors.

Among the important features and objects are the means for producing the graph and for initiating and stopping the feed and for severing the graph-bearing portion of the strip at the termination of a particular program.

Various additional objects and advantages, both specific and general in character, will be apparent from the typical arrangement to be described, and the invention accordingly comprises the features of construction, combination of elements, and arrangement of parts, which will be exemplified in the construction hereinafter set forth, and the scope of Which invention will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention reference should be had to the following detailed description taken in connection with the accompanying drawings, in which:

Fig. 1 is a general view in elevation of an apparatus typifying the invention as installed ready for operation;

Fig. 2 is a wiring diagram of the circuits of the apparatus of Fig. 1;

Fig. 3 is a perspective view of certain elements in the interior of the main casing comprising particularly the graph-forming element and the means for varying the transverse position thereof;

Fig. 4 is a view of a portion of a film bearing thereon a graph representative of that which would be obtained normally in the operation of the apparatus;

Fig. 4a is a diagrammatic illustration useful in connection with Fig. 4 in describing successive positions of the manually adjustable pointer;

Fig. 5 is a front view in elevation of the recording instrument with the dial removed better to show some of the internal construction taken on the line 5-5 of Fig. 6;

Fig. 6 is a cross-sectional view in elevation taken on the line 6-45 of Fig. '7; and

Fig. 7 is a view from the rear with the back cover plate removed.

The general features of the apparatus are shown in Fig. 1 and comprise a recorder box It connected through the cord ii to the combined plug and relay switch 12. In the installation of the device the switch box I2 is secured in an alternating current outlet such as the normal one found in a home. For this purpose the casing i2 is provided with ears 13a and B1), the ear l3a being utilized in the present typical installation and that of I31) being provided for use in another type of standard electrical outlet. As shown diagrammatically in Fig. 2, the box 12 has at the rear thereof a pair of prongs l4 adapted to fit into the normal plug outlet. The box i2 is provided with an auxiliary outlet l5 stallation of the device does not deprive the home owner of any normal outlets. The attac'nng screw which is adapted to occupy the normal position of the screw hOlding the face plate in position on the wall, may have a special head requiring a special tool so that the switch box [2 cannot readily removed by unauthorized persons.

As shown in l and 2, a key I? is provided ".esigned to be inserted in an appropriate slot hereby closing the switch l8, which is then normally maintained closed by the electromagnet 8 connected across the two main leads through connection which may include a suitable re- 'stance switch l8 includes, of course, part composed of iron which is attracted by c electromagnet Hi serving to hold the switch upper closed position against the force of own weight when the current in the coil of the electromagnet is sufiiciently lar With the arrangement shown, the circuit will remain closed unless and until there is an interruption in the main line, whereupon the switch it? will be opened, and remain open, until closed by reinsertion of the key 37. This relay switch arrangement has a special purpose, as will be desc bed more in detail hereinafter. \Vhen the circuit has been interrupted and the switch It! opened the pilot lamp 2i, which may be a small neon bulb, located in back of the colored glass window 22 will be lighted. With the switch [8 open the circuit for warning light includes the line 23, the winding of low resistance of the motor 32 to be later described, and back to the other main line of the source of electric power. There is also a further circuit connection for the light in parallel with the motor winding comprising the line 23, a suitable resistance 24, the bulb 22, wire connection 25, solenoid l9 and through resistance 2i back to the other side of the circuit.

he pilot lamp 2!, and its resistance 24, are shunted around switch l8, and since the lamp is i high resistance practically no current will flow through it when switch i8 is closed. When, however, switch lfl is open the voltage applied to the pilot lamp will be high causing it to light. As to the s itch ill, after it is manuall closed by insertion of the key N the direct connection across the line through the coil of the electromagnet i9 and the resistance 2!} will permit a relatively high current in the coil sufficient to hold the switch closed. After the circuit in the main line has been broken, however, as by removal of plug connection M, and the connection thereafter restored, the circuit for the coil of the electrcmagnet [9 will comprise the line 2-3, resistance 2d, lamp 2!, line 25, electromagnet coil to and resistance 26 to the other side of the main power circuit. In that case, because particularly of the high resistance of the pilot lamp, the current through the coil of the electromagnet I 9 will be too small to draw the switch l8 across its gap to the closed position. The circuit for the recording box to will be described in detail hereinafter.

Referrin to the mechanical construction of the recorder contained in the case Hi, there is shown a pointer 23 secured to and adapted to rotate the main control shaft 29. The pointer 23 moves over a dial 30 secured to or forming part of the front cover 3| of the box It]. The dial 353 may bear any suitable indicia, such as that shown in Fig. 1. As there depicted the dial indicates Ofi and Neutral positions and also intermediate like or di like. into operation in described, the opera rogram and adjusts the pointer lit to various positions corresponding to his reaction to the program '-t any particular inst t, adju ents made from time to time his reaction to the program changes with the sucoes. events thereof.

The main drive motor shown and comprises, in general, a syn sous motor connected directly to the leads from the switch box l2 so that the mot n oral y operates continuously regardless the pc n of the control pointer 28. The motor 3 mounted on a swinging frame 33 pivoted at I norniaily urged, as shown in 7, clo u e or to the right about its pivot 3 means i he Mounted loosely on the end oi the control shaft 29, that is on the end oppo i e to the pointer 23, is a rotary cam 33 having thereon projecting pins 37 adapted to be the lug secured on the rear end of the shaft T39. lost motion is thereby provided between rotary control shaft 25 and the angular ustment of the cam member which is ted to control the position of the motor shown in Fig. '7 the motor frame is povideo. n a plain bearing surface .33 ado ted to be y the portion ll) of the cam which ie motor in a position to the left. motor is connected through st ive the shaft 4!,

The appar tus d with a suitable means for feeding a sheet 2". aterial adapted to receive the graph. As specifically shown in the present device, th s comprises a strip material such as a motion picture film, the main supply roll being shown at 43. The feeding means for the strip of film comp; a pair of sprockets 45 connected together by the tubular member 551 and mounted on the shaft The shaft 5| is suppo ted in a pair of spaced brackets 52 secured to the plate one of such brackets being shown at the right in Fig. '7 and the other occupying a similar pos tion to the left of the sprockets. shaft is may extend through inc and form a bearing for the support of the driving clutch member The driven clutch member 44 is secured to adapted to cause the rotation of the sprockets An arcuate plate 54 assists in guiding the film which is fed the sprockets upwardly in Figs. 5, 6 and '7 and out through an exit 55, the exiting oi the film being shown at 48a in Fig. 6.

The means for producing the graph in the present specific form of the invention includes a heated wire movable in a d ection transversely of the film 43 and adapted to cut a path therein extending generally longitudinally of the film but Varying in its transverse position in accordance with the position of the pointer Such a cutting element is shown at 59 comprising an electrical resistance wire of suitable composition such as Nichrome. The wire is carried at the outer and upper end of a bar Gd pivoted at El and having secured thereto at its upper end an outer loop member 62 designed to provide a support and electrical ground for the inner or lower end of the cutting element 59. The circuit includes an insulated wire 63, which may extend up the bar 69 from its pivot to the upper or outer end where it is connected to the resistance element 59 through an insulating bushing 94 shown particularly in Fig. 2, the current passing through the element 59 to the metal loop 82 at the point 65 (see Fig. 2) which is grounded to the frame. The source of current is from a transformer 66 (see Figs. 2 and '7) and the complete circuit through the cutting wire includes additional elements as will be described more fully shortly. The pivoted lever 69 is normally urged clockwise or to the right in Fig. 5 by means of the spring 98, its exact position being controlled during normal operation by cam means mounted on the control shaft 29. This cam means comprises a first cam 69 of progressively varying radius rigidly secured to the shaft 29, and a second cam 19 loosely mounted on shaft 29 to rotate independently. The cam 19 has an upturned lug ll adapted to be engaged by the edge surface 12 of the cam 69, the construction comprising a lost motion connection between cam 69 and cam if) for purposes which will be described more in detail shortly.

The construction also includes a timing means for applying timing marks to the film 48 as it is being fed, which will now be described. This likewise includes a heated wire resistance element shown at 15' carried on an arm 16 pivotally supported at 11 in a fixed bearing 78. The end of the bearing portion 'li opposite to the swinging arm '16 carries another arm 19 having a rightangled finger portion 89 adapted to engage the cam 42 heretofore mentioned mounted on the rotary shaft ll. The motor and correspondingly the shaft 4 I and cam 92 rotate continuously. The finger portion 99 of the notching device just described is caused to be maintained in engagement with the cam 42 by the spring 8! connected at one end to the arm l6 carrying the resistance element l5 and at its opposite end to a suitable frame part. The cam 42 rotates in the direction of the arrow shown in Fig. 6, and once in every revolution thereof the finger 89 drops into the notch 42a of the cam 42 swinging the heated element 15 into engagement with the edge of the film, and then is slowly moved away from the film by the increasing radius on the cam 42 whereby a notch is produced in the edge of the film of a character similar to that shown at 82 in Fig. 4.

The electrical connections for heating the resistance element 75 are shown diagrammatically in Fig. 2 and comprise a lead wire connection 84, which passes through insulating bushing 85 located in the arm it, the opposite end of the resistance element 79 being connected back to the metal part of the arm i9 and from there is grounded to the frame.

As shown particularly in Fig. 6, the straight bearing portion l? of the timing device has secured thereto another arm 90 bearing at its outer end a flag 9| operated behind the window 92 located in the rear cover plate 93 of the casing where it may be observed for the purpose of initially timing the apparatus, as will be more fully described. It may be noted here, however, that when the finger 8i"! drops into the notch 42a on cam 42, the flag 91 is brought into full view before the window 92 and it is subsequently slowly swung partially or completely out of View.

A switch for controlling the circuit is shown at 96 which may conveniently be of a toggle type having a snap-over lever 91 adapted to be moved to the left in Fig. 5 to the closed position by the stud 98 secured on the cam 69, and moved to the right to its open position by engagement of the face 91a thereof by the bar 60 when the bar moves to its extreme clockwise position, that is, to the right in Fig. 5.

The circuit under the control of the switch 96 is shown more clearly in Fig 2. It includes a transformer 66 having a secondary coil I00 for the heating elements 59 and 15 which are in series, and another secondary coil IOl providing a source of electric power for the pilot light I02. As shown in Fig. 6, the pilot light I92 is mounted to the rear of a window H13 in the front cover plate 3| which may have a suitable colored glass therein. The pilot light indicates when the circuit to the heating elements is closed and the device ready for operation. As is also shown in Fig. 2, the motor 32 is connected directly across the line and is not under the control of switch 96 and, accordingly, the motor operates continuously while the relay switch l8 remains closed. A

suitable fuse shown diagrammatically at I04 may.

be inserted in the line.

Having described the structural features of the apparatus, it is believed that the general arrangement and relation of the parts will be made particularly clear by describing its operation through a complete typical cycle. It will be assumed that the pointer 28 is in the Off position as shown in Fig. 1 and correspondingly that the bar carrying the cutter element 59 is in the full line position shown in Fig. 5. The various successive positions of the pointer are shown in Fig. 4a and the corresponding positions of the cutter element 59 in Fig. 4. The initial Off position just described is designated position a in these two figures. Assuming that the operator is going to use the device in connection with a radio broadcast and that the program has begun or is about to begin, the device is put in operation by turning the pointer clockwise. During the initial movement of about degrees to position b, the upper cam plate 69 will have engaged the lug H of the follower cam 10 and rotated the latter to the dotted line position of Fig. 5 moving the bar 60 to the extreme left and correspondingly moving the cutter element 59 to the position b in Fig. 4. In this movement the cutter element will pass beyond and free of the end of the film which will have been cut off along some line represented by a-b in Fig. 4 in the last previous operation of the device.

Continuing the rotation of the pointer clockwise to a point approximately that shown at 0 causes a pin 98 on cam plate 69 to engage against the arm 91 of toggle switch 96 snapping the arm to the left and closing the circuit to the transformer, which causes current to flow in the resistance wires 59 and I5 and also illuminates the pilot light I02. In its position to the left, the arm 91 is out of the path of pin 98 in its further back and forth movement. Continuing the rotation of the pointer to the Neutral position in Fig. 1 indicated at d, Fig. 4a causes the lug 38 on the lower end of the control shaft 29 to engage the upper pin 31 on cam 36 as shown in Fig. '7, rotating the cam counter-clockwise in that figure, permitting spring 35 to swing the motor frame to the right engaging clutch members 43 and 44, which starts the feed of the film 48.

It willbe noted that during the rotation of the pointer from position b to position 0, the lower cam plate It will have passed its high point and the spring pressure on the bar 60 has forced the loose plate 10 around in advance of the cam plate 69 whereby cam plate 10 no longer func tions and the bar 65 from this point on bears against and follows the upper cam plate The device is now operating, the film being constantly at a slow rate, and the operator from time to time adjusts the pointer back and forth between the points marked minus 2 and plus 2 in Fig. 1, and, accordingly, the heated cutter e ement 59 proceeds along some such path as indicated by the line 105 in Fig. 4 severing the film along that line. The Neutral or midpoint is indicated by the line N16. The film should be of non-inflammable material such as the cellulose acetate type.

At regular intervals, that once every revolution of the cam 42, the notcher or timer wire 5 is brought into engagement with the edge of the film producing a cut-out notch therein resembling that shown at 82 in Fig. 4 as heretofore mentioned. The rate of film feed by suitable proportioning and arrangement, be made substantially an value desired but normally will be relatively slow. Correspondingly, the apparatus may be designed to operate the timing element at whatever intervals desired. As illustrative, ten minute intervals have proved satisfactory, the film being fed three inches in such interval.

Assuming the device has been operated through a program and that at the end thereof the pointer occupies some such position as indicated at e, and the operation is to be terminated, the operator merely turns the pointer in a counter-clockwise direction to the Off position. During this movement, and at a point substantially before the Off position is reached, the lug 38 on the lower end of the control shaft engages one of the pins 31 and rotates th cam 36 clockwise, in the rear view of Fig. '7, to the position there shown, disengaging the clutch plates 43 and M and stopping the feed of the film. During this same rotation of the pointer the upper cam plate 69 will engage the lug H on cam plate 10 rotating the plate H) to a position such as shown in Fig. 3 moving the arm Eli to its extreme left-hand position and bringin the cutter wire 59 outside the left edge of the film to the position represented by f in Fig, i. The relation preferably should be such that the cam 36 has released the clutch drive to the film a lit tle in advance of position J. The positions for cams 6,9 and 13 corresponding to position J are shown in Fig. 3, and also in dotted lines in Fig. 5. Continued counter-clockwise rotation of the pointer from position f to the position a brings the high point of the cam Iii below dead center, whereupon the cam plate H1 is advanced by the pressure of the bar to a position such as shown in full lines in Fig. 5. During this latter movement of the bar to under the pressure of the spring 68 the bar engages against the face Sla of the toggle switch lever snapping the switch to the right. to its Off position, In this same movement 0f the bar 60 from the extreme lefthand to the extreme right-hand position, the heated wire 59 moves entirely across the film severing the portion bearing the graph along some such line as that indicated at f-a in Fig. 4. It will be appreciated that the operation from the point e, that is, when the operator dete mines to shut oil the device, comprises merely a rapid. continued movement of the pointer through secured therein, but thi less than a complete rotation, and that accordingly the events just described occur very quickly and that the cutter wire is in substance snapped across the film under the pressure of th spring 68.

The portion of the film which has been cut oil and which bears the record graph is now availfor and whatever use thereof that vo. She apparatus and additional film therein are available and ready for operation in connecti n with other programs whenever de- Proper initial installation of the apparatus assures that the graph can be accuratel events of the progra'.
