.Application filed September 13, 1913, Serial No. 789,643. Renewed March 18, 1915. Serial No. 15,386.

To all whom z't may concern r Be it known that-I, ORLANDO E. KELLUM, a citizen of the United States, residing at Los Angeles, irthe county of Los Angeles, State of California, have invented new and useful Improvements in Sound Transmission and Recording, of which the following is a specification.

This inventionfrelates toa device for. -transmlttlng and recording sound, especially in making .sound records for use in talking moving plctures; and the invention consists in the novel features of the sound `transmitting and recording device and broadly in the combination olf -such device-"with a synchronously operating moving picture camera; the prime object of the invention beingthe easy and efficient production` ,gf synchronous sound kand visual .chronously reproduced in records which may be subsequently synproper Acorrespondence to each other.

In its now preferred form, my invention Includesja sound recorder and electrlcal transmission apparatus; said transmlssion apparatus including a telephonie transas to be easily engaged by the contacts mounted upon the person while the mitter or the like placed upon a person, a telephonlc receiver or the like coperating with the sound recorder, and electrical connections between the transmitter and receiver of such nature as to allow the-person to move within the field ofview ofthe motion picture camera and to be audibly in connection with the sound recorder. These connections may be made in a variety of manners so as to be invisible yor practically invisible to the motionypicture camera.I I

.prefer to use contacts mounted upon the person and contacts which are stationarily 'distributed about the field of view. The

stationary contacts ymay be distributed so assumes natural poses atwill; the contacts either being in the fiooror; on the various `furniture in the vicinity, or both. AnL l. other means which I may. use will includea line Wire connection directlyfrom the person -to the recorder, or ,the electrically actuated apparatus thereof, said Wires being of a size and color to not be discernible in the motion picture.

I have shown preferred forms of my apparatus in the accompanying drawings, in which, l

Figure 1 is a view partly in perspective person and partly in diagram showing my com- IE `lete arrangement in its preferred form,

ig. 2 is a diagram showing the electricaly l arrangements thereof, Fig. 3 is la view showing a possible construction Nof the sound recording apparatus, Fig. 4 is a diagram illustrating a modified form of apparatus, with a telephonie. relay included therein, Fig. 5 is a diagram showing such a telephonie relay as I may use, Fig. 6 is a detail showing a method ofmounting a contact upon the person, and Fig. 7 is a view similar to Fig. 1 showing the connections made from the person to the sound recorder by'direct wiring.

In the drawings the numeral 10 desig- 'nates' a sound recording apparatus, 1 1 a moving picture camera and 12 a 'personl whose actions and speech it is desired to record. The movingpicture camera l1 and the sound recorder 10 are operated synchronously, being connected by means ofA wires 13 so. that they operate together. This species of synchronous coperation may be the same as s hown in my Patent No. 1,027,658.' dated 'May 28th, 1912. In the preferred form of my synchronous operatrecording-stylus 15, the diaphragm 16, and I a means 17 lfor electrically transmitting to the .diaphragm the sound vibrations which are originallyproduced by the speech -of a person and. which are ultimately recorded upon the record 14. The device 17 may be of any desired character, and may coperatewith the recording stylusl in any manner.

A s a simple arrangement, I have shown' a telephonie receiver apparatus having a dia'- phragm 18 and electromagnet 19, the'magnetically caused vibrations of the diaphragm producing sound Waves which impinge upon v the stylus diaphragm 16; or the arrange- .lnent may be made to combine diaphragme.

16 and 18 into a single diaphragm. The arrangement illustrated has the advantage of taking the weight of thetelephonic receiver apparatus ofi' the stylus.

Wires

20 and 21 connect tothe receiver, Y

and Ythe wires may include in circuit, asis shown in Fig. 2, a battery 22.' From V,wires 2O and 21

branch wires

20 and 21a lead to various contacts 23 and '24, which may be distributed about the space in which the person is moving. These contacts 23 and 24 may be placed on the vfiner .or furniture and the wires 20% and 21' may pass-beneath the carpet or rug or may be concealed in other manners; or they may be of such color and of so small diameter asto be invisible or practically invisible in thefinal motion pic-` ture. The contacts 23`and 24 may be made small so as to be unnoticeable, or may be built into the various furniture in such man-l ner as to apparently form parts thereof. It

is only necessary that one of contacts 23 and one of contacts 24 be connected with in order to establish a complete circuit; and

these contacts may be engaged by finger contactsor footcontacts on the person, or by both.

The personal equipment vof my device consists preferably in a suitable telephonic transmitter 30 which is placed in any Suita-hleposition Von the person, being placed against the persons chest and either held in position by a suitable belt 31 or by. mere pressure of the clothing. Various wires 20b and 21b may proceed :trom the opposite sides of the telephonie transmitter and may terminate in

suitable contacts

26 and 27 which may be mounted in convenient positions on the person. vAs indicated, the contacts'may be mounted either on the hand or on the foot; and in Fig. 6

I have shown in detail the mounting of a hand Contact. In -this ligure, the contact may consist of a thin flexible contact strip 31 mounted upon a finger ring of ordinary appearance, the contact strip being on the inside of the linger where it is not noticeable and where it may be easily engaged with the stationary contacts. fore stated, it is only necessary. that one set from the transmitterl 30 will lead'xto. bind.

ing'posts .41 and 42, and-the 4wires 20 and 21-c leadingvto the recording apparatus will lead from binding posts 43v and .44.. The battery 22 is used as in the device of 2, while-.auxiliary` battery 45 isusedon the as `for instance y As hereinbeot contacts on each side of the circuit .be in engagement. Thus,A the circuit may run sists essentially in adouble wound magnet 50 havinga, winding.. ,lfponnected directly to the bindingposts 41` and 42. This double wound-.magnet :vibrates a vibrating armature 521whi'ch coperates with adjustable contact.53, .the variations in the secondary Vnirren't f'the relay being made by variations. of resistance at" the contact 58. The winding 54 of the magnet 50 is in series with thecontact`53; and this series circuit connectsdirectlv to the

binding posts

43 and 44. This form of. relay is well known tothe l art,l I'may use this form or any equivalent form. Ll

vInltigx 7 I have shown an arrangement practicallythe same as that shown in Fig. 1, vin whichI eliminate the. contacts 23, 24, 26and 27 and connect the transmitter 30 lon the person directly with the recording apparatus by means ot line 'wires 20c1 and 21d.

These wires may be passed through the l' clothlng of the person to the Hoor and may then lie loosely'. on the floor and connect with the sound recorder.- They may be of such color and such diameters as to be invisible or'practically invisible in the ultimate moving picture. Y
