CLYDE J. COLEMAN, OF NEW ROCHELLE, NEW YORK.
COMBINED MOVING-PICTURE MACHINERY AND PHONOGRA'PHIC APPARATUS.
Specification of Letters Patent.
Patented Aug. 5, 1919.
Application filed August 21, 1915. Serial No. 46,629.
To all whom it may concern: 7 I
Be it known that I, CLYDE J. COLEMAN, a citizen of the United States, and a resident of New Rochelle, county of Westchester, and State of New York, have invented certain new and useful Im rovements in Combined Moving-Picture graphic Apparatus, of which the following is a specification. w
My invention relates to synchronized moving picture apparatus and 'phonographlc apparatus. 1 v
One object of my invention is to mechanicall reproduce sounds in true synchronism with the projection of images portraying the original production of the same sounds.
, Thls object is attained by using a phonograph recordv on a reproducing machine and simultaneously passing a correlated series of pictures through a projectin machine, the two machines being operate in true synchronism whereby the'sounds and images mutually cooperate to interpret one another.
Another object is to secure realism in the simultaneous production of sounds and images. This is attained by positioning the sound-producing mechanism in such close proximity to the images as to produce the illusion that the sound emanates from the image itself. positioning the sound-producing machine so that the sound passes through or very close to the edge of the screen onto which images are projected. A
Another object is to correlate thetwo machines so that they may besimplyand accurately synchronized. This object is attained by avoiding the complexities arising from synchronizing widely separated machines by mounting them so that they are operated from a common source of mechanical power, but the operation of one machine does not in any way impair the operation of the other. Both machines are mounted behind a translucent screen and the images are projected through the screen and the sound passes through it or around it.
Other and further objects and advantages will appear from the description of my 1.11- vention taken-in connection with the rawin forming a part of this specificatiomand wi ll be pointed out in the claims.
In the single figure of the drawingse a preferred form of my invention has en illustrated. I do not, however, intend that my invention shall be limited to the precise the achinery and Phono- This object is attained by' form disclosed by this specification, but intend that it shall include such modifications as may occur to those skilled in the art, and that my invention shall be defined only by the hereunto appended claims.
In the device shown in the figure, a moving picture rojecting device 1 is mounted upon an ordinary pedestal 2 and upon this pedestal is mounted a source of light 3 from the lens 4 of which the light is passed into after passing through the film, leave the pro ecting mechanism through a second lens 5 and pass onto the translucent defining screen 6. This screen is made translucent because it is intended that the picture shall be viewed from the opposite side of it from that on which the Projecting mechanism is situated. An electric motor 7 receives electric ower from the source 8 through the spec -controlling rheostat 9 and a worm 10 on a motor shaft 11 drives a Worm wheel 12 mechanism, or phonograph 20. Between themoving picture machine and the phonograph there is ositioned sound-deadening or vibration-absorbing material 21 to prevent the vibration of the moving picture machine from being transmitted through the soundre roducing mechanism into the sound-magni ing horn. The phonograph driving shaft 22 has mounted upon itxa wheel 23. Mounted u n' the phonograph casing is a bracket 24 in which is journaled a shaft 25. On the upper end ofthis shaft 25 is a wheel 26 which cooperates with the wheel 23. The lower endof this shaft 25 carries a coupling member 27, and adjoining the coupling members 19 and 27 there is sound-deadening and vibration-absorbing material 28. It'will be seen, therefore, that there is no mechanical connection between the phonograph and the moving picture machine which is not rovided with means for preventing any of the vibrations of the moving picture machine the projecting mechanism. The light rays,
. from: interfering with the pro er operation with the opening 32 in the screen, said opening, as shown, being above the picture portion of the screen; and both the opening 32 and the exit opening of the horn may be of small area relatively to the picture portion of the screen. It will be seen, therefore, that when a picture is reproduced on the screen by driving the kinetoscope by .means of the motor 7 the phonograph by reason of being mechanically connected to the moving picture machine, is driven in exact synchronism and the source of the sound is so close to the point where the images are defined by the screen that an illusion is produced in the mind of the person viewing the images whereby it appears that the sound emanates from-the images themselves. It will be seen that by positioning the moving picture machine behind the screen I am enabled to connect the phonograph directly therewith by mechanical means and thereby secure absolute synchronism without experiencing the difficulties ordinarily encountered when it is attempted to synchronize widely separated machines. Both the moving pic ture machine and the phonograph are con-- cealed by the screen.
Other means for securing synchronous operation of phonographic and moving picture machines are disclosed in applications for atent filed by me for improvements in synchronizing mechanism, Serial Number 46,630, filed Aug. 21, 1915, and for improvements in combined kinetoscopic and phonoaphic apparatus, Serial Number 46,628, filed Aug. 21,1915.
Having-thus described myinvention, what I claim as new and desire to secure by Letters Patent, is
1. In an apparatus of the class described, the combination of a translucent screen, a sound re roducing machine, a moving picture mac 'ne arranged behind said screen, one of said machines being mounted on the top of the other, means for driving one from the other, and means for preventing the transmission of vibration from one to the other.
of the sound, mean for drlving said ma chines in synchronism, and means for preventing the transmission of vibration fro one machine to the other. I
3. In an apparatus of the class described, the combination of a translucent screen, a moving picture machine located behind said screen and arranged to project moving images thereon, a reproducing phonograph located behind said screen, said screen having an opening therein, and a sound-conducting tube extending from said re roducing-pho: nograph substantially to sai screen to the side of the rays projected from the said motion picture machine upon said screen and delivering the sounds produced through said opening into the space in front of said screen at a point substantially in the plane of said screen and at the apparent point of origin of the sound.
.4. In an apparatus of the class described, the combinaton' of a translucent screen, a moving picture machine located behind said screen and arranged to project moving images thereon, said screen having an opening outside of the picture portion thereof, a sound-reproducing machine located behind said screen, a sound conveyer extending from said sound-reproducing machine substantially to said screen to the side of the rays projected from the said motion picture machine upon said screen and delivering the sound produced by said sound-reproducing machine through saidopening into the space in front of said screen at a point substantially in the plane of said screen and at the apparent point of origin of the sound, the exit of said sound conveyer being of small area relatively to the picture portion of said screen.
In testimony whereof, I have signed my name to this specification.
. CLYDE J. COLEMAN.
