The present invention has for object 8. record serving for the projection of cinematographic views in synchronism with a phonographic audition.
This record has, for that purpose, two concentric portions, one of which is transparent and bears a series of cinematographic images arranged according to a spiral, and the other carries the protuberances and hollows serving to produce the desired sounds and also arranged according to a spiral; both spirals can have different pitches, but have the same number of turns, and the angular distances of the images and of the corresponding points of the phonographic groove are the same, starting from the origins of the respective spirals.
The accompanying drawing, illustrates, by Way of example, a form of construction of a record in accordance with the present invention.
Fig. 1 is a' diametral section of the said record.
Fig. 2 is a top plan view.
1 designates a record, made of glass or other rigid and transparent material, of small thickness. This record or disc carries a layer of gelatin or other transparent material 2 bearing a series of cinematographic images 3 arranged according to a spiral and separated from each other by black or opaque' spaces 4..
For obtaining a projection lasting, for instance, for about three minutes at the rate of 27 images per second, an annular surface having an external diameter of 50 centimeters and an internal diameter of 20 centimeters, can be used, the images being arranged according to a spiral having turns, and the intervals 4 having a length equal to about one and a half times the length of the images 3.
The record being adapted to receive a continuous movement of rotation, it will be advisable, for obtaining the fixity of the projection on the screen, to make use of an optical. device having movable elements: mirrors, prisms or the like, which move in synchronism with the images 3.and in such a manner as to compensate their displacement.
424,410, and in France November 20, 1929.
The opaque spaces 4 are adapted to occult the passage of the light during the movements of the said movable parts which alternate with those directly serving to compensate the displacement of the images.
The layer 2 or annular film bearing the images is covered by a glass ring 5 serving to protect it.
At the center of this ring is inserted the disc 6 bearing the phonographic inscription 7, arranged as usual according to a spiral oove.
Preferably, the external contour of the disc 6 and the internal contour of the ring 5 will be given a polygonal shape, so as to cause these two members to rotate together. 7
The record thus constituted is perforated at its center with a hole for fitting over the vertical shaft 8 which will cause it to rotate and on which it can be secured, for instance, between a supporting plate 9 and a washer 1O acting as a nut. studs 11, secured on the plate and fitting into holes provided in the record, will ensure the angular position of the latter relatively to this plate and to the driving shaft.
One or more tenons or It is to be understood that the invention is not limited to the form of construction illustrated and that, without departing from the scope of the said invention, the details of construction can be modified; for instance, the record 1 can be reduced to a ring of trans parent material limited tothe surface bearing the images, the central portion of the record being only constituted by the disc 6 or 'phonogram; likewise, the mode of assembling and securing the parts to each other can emodified. On the other hand it is not indispensabl that each image and the corresponding portion of the groove 7 be on one and the same radius; in fact, they can be placed on two different radii,-provided' the angular interval of these iradii remains constant for all the images- We claim:
1. In a record for synchronous cinematographic projections and phonographic auditions, the combination of a. transparent disc bearing a series of cinematographic images arranged according to a spiral, a second disc concentric with the first one and integral with the same and in which is provided a phonograpliic groove also in the form of a spiral, both spirals having the same number of turns and the angular distances of the images and of the corresponding points of the said groove, starting from the origins of the said respective spirals, being equal.
2. In a record for synchronous cinematographic projections and phonographic auditions, the combination of a transparent disc bearing a series of cinematographic images arranged according to a spiral, a second disc concentric with the first one and integral with the same and in which is provided a phonographic groove also in the form of a spiral, the said images being separated by opaque intervals having a length equal to about one and a half times the length of the images.
3. In'a record for synchronous cinematographic projections and phonographic auditions, the combination of a transparent disc bearing a series of cinematographic images arranged according to a spiral, a second disc concentric with the first one and integral with the same and in which is provided a phonographic groove also in the form of a spiral, the entire record being constituted by a thin plate of rigid and transparent material, a layer of gelatin bearing the images, a transparent ring covering this layer and in which is inserted the second disc.
4. In a record for synchronous cinematographic projections and phonographic auditions, the combination of a transparent disc bearing a series of'cinematographic ima es arranged according to a spiral, a second isc concentric with the first one and in which is provided a phonographic groove also in the form of a spiral, the first disc being provided with a central recess of polygonal shape and the second disc having a similar polygonal shape and being inserted in the said recess of the transparent disc.
5. A composite disc film comprising an annular band portion carrying a picture record, 'a central disc portion carrying a sound record, and means joining the central disc portion with the annular band portion.
In testimony whereof we have hereunto affixed our signatures.
