This invention relates to devices for-synchronizing a phonograph with moving pic-- electro-magnetic means being energized or deenergized in synchronism with the moving picture film, and provide for this purpose a strip preferably separate from the film but having a length the same as the film and operating at the same speed, this strip having thereon studs which act to break a circuit or make a circuit between the source of energy and theelectro-magnetic means. v A still further object is-to provide means for holding the sound box and its associated parts in properpositinn with relation to the phonographic record so that as soon as the stylusand the sound box are lifted from the record, means will be provided for holding the sound box and stylus in the same approximate relation to the sound record that they were when they were lifted so that when the sound box and stylus are depressed, the stylus will start sound transmission approximately at the point where it left ofl".

Another object is to provide devices for this purpose which will permit the records to be readily changed at any time.

Other objects will appear in the'course of the followingdescription. 1

Bum TAYLOR Annnns- Figure 10 is a side elevation partly in sec-.

tion showing the means for raising or lowering the tone arm of a cylinder record-phonograph.

Referrinfl to Figure 1, which illustrates the part of the mechanism which is used in connection with the niovin tor, 10 designates a support ng base which is supported on adjustable legs 11 andwhich carries upon it the supports 12 for the bearing 13, which in turn supports the shaft 14 of a -reel 15. Upon this reel a tape 16 is wound,- as will appear more fully hereinafter.

Disposed in the bearings 17 is a shaft 18 which carries upon it the take-up reel 19 over which the tape 16 is wound. This shaft 18 carries upon it the gear wheel 20, which in turn is driven by a pinion 21 which is carried onany shaft of the projecting machine, which v gagement with the gear wheel.

Disposed between the two reels 15 and, 19

is aroller 25 (see Figures 4 and 5) having a 'width equal to the width of the tape 16 and this roller upon its face has the alternate indentations and projections, the indentations picture proj ecor recesses being designated 26, and over the face of this roller the tape 16 passes. This tape 16 carries upon it at intervals the studs 27 and when one of these studs in the course of its travel reaches the roller 25 it will engage against a tooth 26a and will rotate the roller 25 a predetermined distance as, for instance, one-twelfth of the circumference of the roller. The projection or stud then escapes from its engagement with the toothed face of roller 25 and the roller does not move again until another stud 27 comes in contact with the toothed faces and rotates the roller through another one-twelfth of a revolution. This roller 25 is mounted upon a shaft or axis 28 which carrier upon it the ratchet wheel 29. This shaft is mounted in bearings 30, in turn carried by a supporting blockor frame 31 attached to the base 10 in any suitable manner.

Coacting with the ratchet wheel 29 is the spring pawl 32 which prevents any return movement of the roller 25. Mounted upon supporting brackets 36 is a roller 37 which bears upon the tape 16 and holds this tape down into contactwith the roller 25. EX- tending transversely through the roller 25 are alternate conducting and non-conducting rods, designated 38 and 89, the rods 38 being conductingrods and the rods 39 being nonconducting rods. These project out laterally beyond the roller 25, as shown in Figure 4, and projecting into the path-of movement of the rods are the resilient contact members 40 which are connected by the wires 41 to the electro-magnetic means for controlling the sound box of the phonograph, as will here after more fully appear.

, Each of these terminals 40 is in the form of a light leaf spring and carries upon it the binding post 42 whereby the wires may be connected. It will thus be seen that when a conducting rod 39 comes against these springs or terminals that the two terminals will be electrically connected to each other and thecircuit closed through the wires 41 at this point, whereas when a non-conduct ing rod comes against these terminals the circuit will be broken or interrupted at this point.

In addition to the roller 37, I preferably provide a roller 43 mounted in guides 44 for the purpose of holding the tape 16 down into proper engagement with the roller 25. If de sired, another roller 43 of the same character mounted in a frame 44 may be disposed in' advance of the roller 37 to guide the tape onto the reel 19.

It will be seen thatwith this mechanism, as the take-upreel 19 is operated in consonance with the operation of a moving picture machine, the tape 16 will be wound up upon the reel 19 at the same speed as the film of the moving picture and that when a stud 27 comes contact with the roller 25 it will shift this roller one step and if, for instance, the electrical connection has heretofore been made across the terminals 29, the shifting of the roller one step will break this electrical connection and, on the other hand, the next stud 27 to come in contact with the roller will shift the roller so as to close the electrical connection across the terminals 29. Thus the circuit formed by wires 41 will be alternately opened and closed by the studs 27. Thus after a speech has been made or other sound produced which relates to the action on the screen, then this sound will be cut off if, for instance, the scene changes or no words or other sound are desired to be reproduced, but just as soon as another stud engages the roller the phonograph or other talking machine will be again started. Thus it will be seen that the talking machine or other phonegraph is alternately stopped and started in conformity with the requirements of the moving picture film.

In Figure 1, I have illustrated the reel as being mounted upon the shaft 18, but under some circumstances it is not desirable to mount the reel in this manner, and in Figure 8 T have illustrated the reel 1% as being dis posed at a height above the gear wheel 20 and l have shown the shaft 18 as carrying upon it the toothed wheel 45 over which the tape 16 passes, this tape passing over this toothed wheel and then up and around the winding reel 19a. This winding reel is driven by a belt 46 which passes around a belt wheel 47 on the shaft 18 and a belt wheel 48 on the shaft 49 of reel 19a. The tape 16 may be wound, therefore,'either upon a reel mounted upon the shaft 18 or upon a reel mounted upon the shaft 49. The reel 19 mounted upon the shaft 18 turns at the same rate as the gear wheel 20, but owing to the increasing radius as the tape is wound on and owing to the irregular outline caused by the studs 27, the tape will not always move at the same rate proportionately to that of the picture film but the rate of winding will increase more or less constantly. If it is deemed desirable or necessary to have the rates of the iilm and the tape exactly proportional at all times. the tape can be run over the sprocket wheel 45 and then wound up on the reel 19a which, being turned by the smooth belt 46, is always exerting a tension on but never positively pulling tape 16.

I will now describe the connections to the sound reproducing mechanism which is controlled by the mechanism shown in Figures 1 to 8 and which has just been described. It

will be understood that any desired phonographic mechanism may be used and that by i the term phonograplf I refer to any sound reproducing machine. In Figure 2, l have illustrated the use of a flat rotatable turntable, and in Figure 10 I have illustrated the use of a record cylinder.

.. (see Figure 3) and in practically all respects is the same as the ordinary tone arm, except that it is laterally extended, as at 54, and passes through a tubular arm 55. This tubular arm carries upon it the sound box 56, which is of an ordinary character, this sound box having the usual stylus arm 57 and the usual stylus 58. The tubular arm 55 into which the tone armopens ,is pivoted or oscill'atably mounted on the lateral extension 54 of the tone arm 53 and is extended rearward beyond its junction with the tone-arm. The tubular arm 55 is balanced by an adjustable counter-weight 61 mounted upon a pin 59'and operating within a slot 60.

' Mounted upon the base-62 of the tone arm is a clamp 63 and this clamp carries upon it the transversely extending pin or bolt 64:

c which at its end is screw-threaded for engagement by the two nuts 65. Mounted upon this bolt 64 as upon a pivot is a lever 66 which extends across the face of the sound box above the lower portion of the stylus-carrying arm. The extremity of this lever 66 carries upon it the short lever 67 pivoted upon the lever 66 at 68." One arm of the lever 67 is downwardly and forwardly turned and carries upon it the screw-threaded member 69, which in turn carries upon it the stylus 70 held inrplace by a set screw or other suitable means. .The opposite end of this lever 67 is pivotally connected to a link 71. This link at its upper end is pivotally connected by a bolt 72 to a slidable bar 73 mounted upon a supporting bar 74. This supporting bar is clamped or otherwise engaged with the sound box 56 and the slide 3 is held in adjusted positionupon the supporting bar 7 4 by'means of the adjusting bolt 75 and the wing nut '76, the bolt passing through a slot 77 in the slide. Any suitable clamping means may be provided for holding this fixed support for the link 71 upon the sound box.

The rear end of the arm 55 is raised or de-' pressed by means of an electro-magnet. ave shown for this pur ose a solenoid coil 78 mounted upon a base 9 which is clamped upon the tone arm and projects out laterally therefrom so that the axis of the coil 78 is immediately above the center line of the arm 55. The core of the solenoid is designated 80 and a supporting rod 81 extends vertically through this core andat its lower end is operatively connected "to the arm 55. The upper end of the supportin rod 81 has a universal joint connection wi the upper end of the core. The upper end of the coil 80 has the binding screws 82 with which the wires 41 are designed to be engaged. One of these wires is connected to a battery or any other suitable source of current and preferably a switch is also disposed in the circuit whereby the circuit ma be manually opened or closed.

Adapte to operatively connect the arm55 I to the lever 66 is a link 83 pivotally engaged with ears 84 on an L 85 which is-attached to the arm 55. The link 83' is provided with a latch pin 86 which extends through a slot 87,

this latch pin being urged inward by. a spring and having a thumb piece 88 whereby the latch may be withdrawn.

The support forrod 66 is the bolt 64, and it will be obviousthat when the solenoid coil 80 is energized the core 78 will be drawn downward, thus pressing down'on the rear end of the tubular ivoted arm55 and lifting up on the sound box to carry the stylus thereof out of engagement with the record grooves on the record 51. Asfthe pivoted portion 55 of the tone arm, the sound box lifts up through the link 71 upon the lever 67,

depressing the positioning stylus 70 into the last record groove of a series, whereupon 'it will immediately run oflf into the next adjacent groove 52 and, so long as the sound box is raised and out of operation, this needle 70 will traverse the groove 52 and the sound box will thus'remain, while it is raised, al-

ways in the same relatiye osition to the central axis of the turnta le but with the mediately above the first sound record track or v groove of the next adjacent band or-series of grooves, this being for the reason that, as illustrated in Figure 2, the positioning stylus 70 and the sound reproducing stylus -58 are disposed slightly out of alinement or offset with relation to each other. When the coil 80 is de-energized, the weight of the sound-box and of the outer end '55 of the tone arm will cause the descent of the sound box and this, through the link 71, will depress the rear end of the lever 67 causing the stylus 7 O to lift from the groove 52, while the stylus 58 will enter the first record groove of the next series of sound record grooves and continue therein in the usual manner. I

Thus it will be seen that whenever the circuit through. the solenoid coil is broken across the contacts 40, the solenoid will be de-energized and the sound box will descend and the phonograph will produce sound. Whenever, however, the contacts 40 are connected by.- one of the conduc'ting'bars 38, the

86 may be readily disengaged from the rod 66 by pressing inward on the thumb piece 88 and then the records may be readily changed, as this allows tone arm section 55 of the sound box and the rod 66 to be raised carrying with it the reproducing needle 58 without causing the corresponding lowering of the position needle 7 0. Adjustments to bring the two needles or styluses 58 and into proper relationship may be made by means of the wing nut 7 6 and by shifting the bar 66 into any one of a plurality of positions of engagement with the supporting bolt 64:.

In Figures 2 and 3, I illustrate a structure particularly adapted to disk records, but in Figures 9 and 10 I illustrate a structure whereby the same'principle may be applied to the control of cylindrical records. In these figures, 89 designates generally the base of a cylinder phonograph and 90' the mandrel upon which the cylindrical record 91 is mounted. This cylindrical record is formed with a plurality of grooves 92 which are exactly the same as the grooves 52 in Figure 2 and act as position grooves, and between these grooves 92 the record 91 is provided with the usual phonogram extending spirally around the record.

Coactin with the record is a sound box, designate generally 93, having a stylus 9d engageable with the record grooves, and this sound box is mounted upon a tone arm 95 extending rearward and operatively connected to a longitudinally extending tube 96 torming the axis of the tone arm which leads to a sound chamber (not shown). Illustrated as formed in one piece with the arm 95 is a con trolling arm 97. This extends downward and forward and is formed on its under side with interrupted screw-threads 98 adapted to engage, when the tone arm is lowered to bring the stylus into engagement with the record, with a feed screw 99 extending parallel to the axis of the record and acting in the usual manner to carry the tone arm longitudinally along the record. This screw is operated by any suitable mechanism not forming partot the present invention and well known to all those skilled in the art.

Pivotally mounted upon the controlling arm 97 is a lever 100 which carries the position stylus 101 adapted to engage in any one of the grooves 92. This lever 100 is forced downward, that is has its butt end shifted in a direction to carry the stylus 101 into engagement with the record by means of the e pin 103. It will be seen that so long as thetone arm 95 is dropped, this phonograph will act in'the usual manner, and when the sprin 102 which is supported by means of 0 tone arm 95 is raised, the stylus 94 will be I carried out of engagement with the record and the stylus 101 will be carried into en gagement with the grooves 92, I 1

For the purpose of raising the tone arm irregular distances. the sentences are short, the positioning 95 to thus stop, in this sense, the operation of the talking machine, I provide the electromagnet 104 which is mounted upon an arm 105 preferably hinged, as at 106, so that it may be moved out of the way, this magnet coacting with an armature 107 mounted upon the tone arm or upon the sound box. In this instance it is shown as mounted upon the sound box. This magnet 10 1 has its windings connected to the wires 41, and thus when a circuit is completed across the contacts 40 in the manner heretofore described, the magnet will be energized and will draw the armature 107 up and lift the reproducing stylus from the record. Simultaneously the controlling or positioning stylus 101 will be lowered and eventually as later and more particularly described will enter a groove 92, thus holding the arm from further movement. The lifting of the tone arm 95 b means of the magnet 104: lifts the arm 97 out oiv engagement with the screw 98 so that the tone arm is no longer fed along the record. As soon as the circuit through the wires 41 is broken in the manner heretofore described, the tone arm will drop and its stylus will come into engagement with the record groove, while the positioning stylus will pass out of engagement with the positioning groove 92.

The arm 105 which supports the magnet is preferably hinged so that it may be turned backward to permit ready changing of the record. As illustrated, the tone arm is mounted upon a supporting member or base 108 slidably mounted upon a base 109. It is obvious that these details of construction might be modified in many ways Without departing from the spirit of the invention.

It will be seen that I have provided means whereby a cylinder record may be used or means whereby a disk record may be used, the playing cfboth of these records being controlled by a tapewhich is actuated or moves coincidently with the moving picture film. Preferably I use a tape in place of a film, but it is understood that a film might be used under some circumstances and the buttons or studs be placed along this film. The tape may be made of steel, cloth, fiber or other material. The studs will be attached to this tape at irregular distances, depending, of course, upon when the sound reproducing mechanism is to be used or when it is to be stopped. The positioning grooves in the disk or cylinder record will also be disposed at Thus, for instance, if

grooves will be very close together. If the sentences are long or if there is a long speech or piece of music, the positioning grooves will be relatively wideapart. The advantage of using tape instead of film to operate the contact rollers is that ordinary film can then be used in any projector which will handle such films without any danger of the film being torn,worn or Otherwise injured. There will be no humps or projections to cause breakage and delay. Inasmuch as the tape runsat a rate proportional to the film, the timing is as exact asif the studs were on the film itself.. Since the tape is run at a proportional rate only, there needbe only a small fraction as much tape as film used.

It is to be understood that the position needle or stylus.70 in Figure 3 or 101 in Figure 10 when lowered to the record does not drop directly into the position crease or groove 52 in Figure 2 or 92 in Figure 9 ut initially engages the'sound reproducing groove or phonautogram which merges into the positioning groove and by so doing car ries the reproducer with its stylus. ast the positioncrease and into such position that it will engage the record groove when the sound box isagain lowered. The use of the positioning grooves upon the record -I deem as very important, as this holds the stylus at the point where the sound reproduction ceases for the time being and keeps the stylus at this point so that when the stylus 'is again lowered the sound reproduction will be picked up at exactly the place it left off at the other side of the positioning groove.

While I have illustrated'certain details of construction and arran ement of parts, it is to be understood that the broad principle of my invention may be embodied in many different forms without departing from the spiritof this invention as defined in the appended claims and that many minor modifications might be made without such departure.
