- SYNCHBONIZING PICTURE-EXHIBITINQ AND SOlfND-RECORD MACHINE.

.To all whom it may concern Be it known that I, Isrnoa'KrrsrEn, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented .certain new and useful Improvements in Synchronizing Picture-Exhibiting and Sound- Record Machines, of which the following is determined number proved a commercial success.

a specification. My invention relates to an improvement in synchronizing moving. picture machines and machines adapted to produce sounds. It is unnecessary here to enumerate all the attempts made in this direction, but so ,far, none of the'devices placed on the market Insuch s stems which were brought before the pub ic, the aim of the designer or inventor was to allow the picture film to run at its required speed andto produce means whereby the speed of the talking machine should accommodate itself to the speed of the picture film.

In contradistinction to so far, I accommodate the speed of the picture film,v to the'speed of the sound machine and produce means whereby for each predetermined length of a sound-record a preof picturesare exhibited and" exhibited simultaneously with the production of the sound through that part of the record line. \Vhen, either through .design or accident, the sound machine either retards or accelerates, the exhibition of the film will also'retard or accelerate in the same proportion;' and if, by design or accident, the sound machine entirely ceases its movement, then the'picpictures on the picture -ture machine will cease its movement simultaneously. 5 I

For the purpose of illustrating my inven- --t-ion, I have reference to the accompanying chine.

In Fig. 1; 1 are the meansto operate the picture machine. here shown as an electric motor, of which 2 and 3 are the wires adapted to be connected to a current carrying circuit. For the purpose of my invention, it is immaterial if the speed and force 2. this motor are above the normal and to actuate this motor, it is only necessary to connect thesame to one of the well known light cir-' cuits. A motor, which takes one-half an ampere at one hundred and ten volts, suffioes for all practical purposes. 4 is the shaft revolved by this motor. 5 is a frictional drive device as an entirety. The diiferent parts of said device are illustrated in detail in Fig. 2. The function of this frictional device is, to allow the motor to normally rotate at a desired speed, even if able devices. 6 is an additional shaft on which are positioned the sprocket wheels 9, 9, for driving the picture and part of the means for retarding the movement of said shaft. As clearly illustrated, part of the frictional device is mounted on the shaft 4 and art thereof mounted on shaft 6. 7 is the light aperture through which the light rays project and across which the picture film 8 passes. This being common to all of the picture film apparatus. it is not necessary to o into detail of the operation of same. he portion of the interrupting means positioned on shaft 6 are designated as an entirety by the numerallO. These means consist here of the stop wheel 11 provided. with the four stops 12, 12", 12 and stop, one picture is brought to view for the purpose of being exhibited on a suitable screen. 13 is the partof the interrupting device placed in juxtaposition and in opried by the shaft 6. This rt 13 comprises here two elect-romagnets esignat-ed by the numerals 14 and 14, respectively, and provided with the two cores 15 and 15,'respec "tively. The coils 16 and 16"are connected together atone terminal and to this termithe mechanism, with the aid of which the film 1s operated, is kept stationary by suitmovement from one stop to the'succeeding' erative relation to the cooperating part carcrates the film 1n the same manner as the well terminal of coil 16 is connectedto wire 18 ture which is positioned between the two gage the sto hsup osed that the electromagnet 16 is as:

The hrush 37 is provided with the wire 40 the brush 39 with wire 41 and the brush 38 with wire 41. In'Fig. 4 which. assaid above, illustrates the electrical connection of the two circuits, one illustrated in connection. with the icture machine and the second illustrate in connection with the sound machine; 35 is the c'ommutator',-.as illustrated; in Fig'. 3; 31 its shaft; 37, 38 and 39 the connecting brushes; 40, 41.

This wire is here shown as provided with the source ofcurrent i'2 and is connected with the interposition of the switch 43 tothe wire 40.. The "wire 18' of the electromagnet-lt 4 shown as brush 38 'and the 14 is.h ere shown as'connected to wire 41 of 'brush 39. For the convenience of the'opera-I tor, 'I'haveprovidedthe sound'record with t the mark and -the operator positions t that in 'practice,

will actuated so; as to be as is illustrated in Fig. 3. and that throu' h before the operator commences placed in a position :toen'gage with one of the'stopping samegcomes in alinemen't andit is supposed that-the operator in placing his film moves the shaft in a'manner so that said alinement shall take place, As long as the motor 30 of the sounding device remains idle, no change will take place in the position of the 'film. It is supposed that the brush 39 touches. before the motor 30 starts, one of the conducting segments'of the commutating part 36'.

it is supposed the connection of this part of the circuit, the armature of the device 13 is thrown to the left and in alinement with the stop 12; as clearly illustrated in Fig. Land that a blank space'of the film is brought to view. As stated above, as long as the motor 30 remains idle, the icture film will remain inthis position. It

as to be stated, that in the operation of my device, the motor 1 of the picture machineis connected .to itssource of' current and, therefore, revolves the operation of the sound producing machine and rcvolves continuously no matter if'the mechanism moving the picture is locked against. revolving or not; thus forthereason that the speed of-the "motor should alwaysbe normal at the moment when the locking means are removed, otherwise, it would take v a unit oftime before the motor has attained full speed. It is now supposed that "the motor 30 is brought intojservice and is revolved at the required and predetermined speed.

It is also supposed that the unit of timefor each rev lution of the motor and. the commutator is equal to the unit of time during which pictures .should' be exhiblted.

" stops, the

movements of the sprocket wheels -9. 9, will and 12, as soon as'thehaving a zero position Letters Patent is During one full revolution of this commutator, the electromagnet 14 will be three times energized and deenergized, so also will be, during this revolution, the electromagnet 14 energized and deener 'zed three times, and the energization 0 these two electromagncts will be alternate. Through this alternate energiz'ation. the armature will be drawn back and forth, that is, to the right and left and the prongs :24 and '25 will alternately engage with ,and disengage from one of the stops 1'2, 12'. 12 and 12. During the time that they are engaged with. these moving picture mechanism will be at rest, but during the time of the movement of the, prongs from right to left. or vice versa. the friction of the device 5 sufiices to move the shaft (3 through the power of the motor 1. It will. therefore. be seen that the be an interrupted"one. in the same manner as the movements are today, if controlled through the Geneva device; and it will also be seen that for each conducting segment of the commutator one movement will take place in the moving picture device and each of these movements will bring to View a new picture.

Through experiments. I have ascertained that if the sound and picture should be S1- multaneously and correctly exhibited, it is best to accompany each picture. during the time of its exhibition. with a sound produced by one inch of sound record, when, therefore. the sound record is of greater or lesser diameter. then it is obvious that-the number of segments of the commutator should also be increased or decreased to suit conditions.

I have discarded all ratchet mechanism through the control of a spring. for the reason that with such mechanism, the ratchet arm has to make two movementsforthe engagement of. each of the stops and such is detrimental, since, first, the spring control may vary and, second, that one of the time units is lost and for these reasons and others notnecessary to enumerate, 1 illustrated.-
