To all whom it mag northern!" Be it known. that AuGUs'r C. MEN,-

citizen of-the United States, residing at useful Improvements in Means of Recording and Reproducing Sound and Motion in Synchronism,of whichthe following is a specification. 7

My invention relates to a means of record ing and reproducing sound and motion in synchronism, substantially as herein shown and described and more out in the claims. v

In the accompanying drawings, Figure I particularly pointed 'is afaceview-of a kinetoscopic film which? is provided with a separate sound-producing, record in the form of a continuous strip and Figi'2 is a cross section-of said film an strip. 1 Fig. 3 is a sectional view of -a combined sound producing and "picture pr0jecting apparatus which is adapted to utilize the combined film and record-strip shown in the several figures. Fig. 4; isfan enlarged side view of a sound repordi-ng or reproducing device, and showing -ga'r i} edge -view of a event, if sound producing, be-audibly repro' kinetoscopic'film and sound record in operating ,re'lationtherewith, and Fig. 5 is front view of Fig. 4. Fig. -6 ma sectional View of a modified form of the apparatus shown Fig. 3. o

The invention involves the production of .a kinetoscopic or moving-picture film and a sound recordin synchronism, so that an object in motion may be pictured and the same duced at the same time." Thus, referring to "photographs diagrammatically. As the art Fig; 1, Ishow a transparent or translucent StIlp Of photographic film (2), having thereon successive photographs of anobject in motion, the square (3) representing such of makingsuch photographs of an object in motion at rapidlyrecurrin intervals of time is well known," a more detailed description is unnecessary and not herein described, ex

cept to say that primarily it is b any action of sensitive substances under the lnfiuence of light. Such films (2 are also usually pro vided with perforate edges- (4) wherebyth film is fed through the moving-picture. ma

1 chine at a predetermined or requiredlspeed.

The photographs are arranged in a warm ous strai ht line sequence unlimited in num ber save by the length offilm, but suficient in number to represent the movements of the object throughout the. extended period of time in taking a'j-series. of pictures. In 7 addition to the foregoing, {also-impress, cut Cleveland, in the county of Cuyahoga' and State of Ohio, has invented certain new. and

"or" otherwise produce in or upon the film, a

with the sound waves made-by the object or Aug, 6,

objects in motion as pictured on the film.

The taking of the successive photographs and the recording of the successive sound V waves. is accomplished simultaneouslyby the motion-picture machine 4 and the sound-res} cording machine," and the double record is produced on the single film in parallel. The

1 sound wave record is represented bythe'dotted; line (5) in Figs. 1' and: 5-, andthe ref diatepoint between. said hotographs and erable location thereof is at one side 0' the; succession of photographs (3).at an interme- 4 .75

material or body of the film itself as shown in Fig; 5 or it may be formed in a separate strip; (6)'- secured to the film (2-) by, a suitable adhesive or mechanlcal fastening, or by both. As shown in Fig. 1 the sound wave record strip (6) is provided with loops or 1 extensions- (7) inbinding or fastening en'- 'gagementwith one border o'f'the film. One

different material can be used from that of the .film, such as a tougher and better wearmaterial than the film. However, strip advantage of a separate strip (5) is that a use in a ;moving picture machineusing,

reels (8. and 9) V I and a series' of rollers (10) which brin'g'the filmopp'osite the usual .l'enses infa' machine-(1'1) of this kind; 11159.5"

making a doublerecord, a rubberor other suitablev roller (12)." is arranged in en film at afp'oi'nt intermediate the carryingroller (10 and opposite the sound regfiigement'with the straightfstretch (13) v of cording or reproducing member (14) ofithesound box (15*fr' of-the-machine. The sound box ('15) as shown represents a well: known 1 type of recording or reproducing instrument having a diaphragm andoperating connece tions. for-the recording or reproducing mem:

ber-ofiiynedlgfl), and a tube or pipe extends-from the sound; box to thesmaller end (it aflaringchambeg or box. (17) adapt- 7 same manner as a horn, or thelihe, and which chamber-nor sound amplifying hoz 'tii') is ed to'distribute and amplify he sound the 1 provided at its front and lar r end with a ound glass or other suitab e screen. upon which the moving-picture is projected by a set of mirrors (18 and 19) which are pivranged within the small end of the chamber or box (17 and both mirrors are inclined relatively as shown to roject the picture upon the screen (21). he screen in Fig. 3, if of glass, is mounted apart from the walls of the chamber or box (17) so that the sound waves may escape through the border space in full volume and measure, or if the screen is of a suitable woven fabric it may be provided with suitable openings. for the sound to pass therethrough. In Fig. 6 I show a pair of screens (22 and 23) which are made of suitable paper or woven fabric and .adapted to be wound on rollers (24) in the same manner as a window shade or ourtain, and either one of the two screens may be used depending upon whether a small or large picture is to be shown. The screen (22) is supported by brackets or arms (25) which pro ect forward from the front wall (20) of the apparatus and an open space is thereby provided between said screen and said wall for a free discharge of sound. By raising screen (22) and lowering screen (23) by means of the rollers 24 respectively the projected picture is made smaller and the sound can be subdued. The bottom wall (26) of the chamber (17) is provided with an opening (27) to pernnt the picture to be projected from one mirror to the other but the sound is not permitted to escape by way of opening (27) as the chamber (28) containing the mirror (18) is inclosed by soundproof walls at all sides. The complete apparatus may be placed in any room,.or upon any stage, facing an audience, and it may be built relatively large or small for public or home use. The mirrors (18 and 19) are shown as of the same size but the may be 'of relatively different sizes, and ,donot wish to limit myself in this particular or to the particular form of sound recording and reproducing device shown,'as theinvention is susceptible of modification and as other types and? styles of devices may be used for the same purpose without departing from the spirit and scope of the invention.

. ing

.reproducinlgj What I claim is:

1. An apparatus for producing motionpictures and sound simultaneously, comprisa motion picture machine and a sound device, in combination with a sound-amp fying chamber relatively above said machine-and flared outwardly and having a screen at its outer end for the pictures projected by said machine, a tube to convey the sound to said chamber from said sound reproducing device, and a set of mirrors on different planes arranged to reflect the pictures onto said screen, one of said mirrors being in the rear end of said chamber.

2. In an apparatus for producing motionpictures and sound in synchronism, the combination of a motion-picture machine with a sound-reproducing device, a sound-amplifying chamber for and above said device having a screen at its outer end and mirrors to reflect the motion-pictures through said chamber upon said screen, one of said mirrors being directly in front of said machine and the other in said chamber, and the chamber having an opening in its bottom rela tively between said'mlrrors.

3. In an apparatus for producing motionpictures and sound concurrently, the combination of a motion-picture machine with a soundproducin device, a flaring soundamplifying cham er for said device having a screen for the motion pictures at the front thereof and openings about the edge of said screen for the assage of sound, a mirror at the rear end o said chamber, and means to project a picture upon said mirror.

4. In an apparatus for producing motionpictures and sound, a motion-picture machine and a sound-reproducing device, in combination with a motion-picture film having a sound-wave record on one edge thereof and a flaring sound-amplifying chamber for said device having a mirror at its rear and a screen at its front for the motion-pictures and openings about the edge thereof for the passage of sound, and a tube from said sound-rcproducing device to the inner and smaller end of said chamber.
