A WATKINS, OI RYE, NEW YORK, ASSIGNOR, BY MESNEASSIGNMENTS, TO ELECTRICAL RESEARCH PRODUCTS IN 0., A CORPORATION OF DELAWARE COMBINED PHONOGBAPH AND MOTION-PICTURE PROJECTOR Application filed October 19, 1926. Serial No. 142,767.
ing machine motor and under the control of the motor driving the projector, the linking of the two devices being so provided as to insure synchronism in operation.
The invention will be more clearly understood from the following detailed description of a preferred embodiment thereof and the appended claims.
In the drawings, Fig. 1 is a vertical crosssection of as much of a talking machine as is necessary for an understanding of the invention; Fig. 2 schematically illustrates the gearing between the talking machine and the motion picture projector; and Fig. 3 illustrates a-detail of the belt drive.
The talking machine casing or cabinet 1 encloses the usual spindle 2 which may be rotated by means of a motor (not shown). Above top 3 of the cabinet 1 and within the projecting edges of the cabinet, the usual turntable (not shown) may be mounted on spindle 2. The talking machine may be used in the customary manner by placing a disc on said turntable and causing a reproducer unit A to cooperate therewith.
If it is desired to use the talking machine in conjunction with a motion picture projector, then the turntable is removed and another turntable 5 is mounted on the tapering free end of spindle 2. For this purpose the turntable 5 has a central boss 6 which is rotatable with respect to a block 7 frictionally held by the end of spindle 2, a suitable hearing such as ball bearing 8 being interposed between boss 6 and block 7. The downwardly projecting rim of boss 6 is formed into a pulley 9 which, as illustrated in Fig. 3, is provided with teeth 10 around its circumference and I is adapted to cooperate with a correspondingly toothed belt 11. The belt 11 is stretched between pulley 9 and a gear wheel 12 mounted on the end of a shaft 13, the other end of which carries a gear wheel 14. The gear .wheel 14 cooperates with a worm 15 carried by the free end of a shaft 16 which is rotated by a constant speed motor 17 driving the motion picture projector 18. Through the gearing, including the belt 11, the turntable 5 is drlven by the motor 17 at a constant speed reduced in ratio with respect to the speed of the projector 18 but in continual synchronism therewith. By placing a disc record 19 on the turntable 5 into cooperation with the reproducer unit A, the talking machine and the motion picture projector will operate in synchronism, one producing sound and the other projecting on a screen 20 the accompanying picture.
Since the details of construction of the talking machine, the projector and its motor drive are well known in the art, I have only schematically illustrated these devices. Any well-known device of this character may be used. By disconnecting the gearing, the projector may be separately used in the wellknown manner. trated, the turntable 5 projects above the cabinet 1. The purpose of this is to allow for a suitable connection with the belt 11 and also to permit the use of larger records than cabinets of customary size would accommodate.
The motor 17 is preferably of a type adapted to operate at a constant speed and it is used for driving the projector as well as the turntable, since the motors usually provided with talking machines are not capable of carrying the added load of a projector and of a larger record.
It will be obvious to those skilled in the art that the various features of the present invention may be varied within wide limits to suit the mechanical construction and operating requirements of well-known talking machines and projectors without departing from the spirit of the present invention.
What is claimed is:
1. In combination, a talking machine having a rotary spindle provided with means for selectively mountin each of two turntables, one of said turntab es having means for en- .gagin said spindle to be driven thereby, said secon turntable constituting an assembly comprising a block provided with means for frictionally engaging said spindle and hearing means for rotatably mounting the turntable upon said block, a projector, a driving means therefor and a dr ving connection between said proi'ector driving means and said second turntab e 2. In combination, a talking machine having a reproducer unit and a rotary spindle provided with means for selectively mounting each of two turntables for carrymg records which cooperate with said reproducer unit, one of said turntables having means for engagin said spindle to be driven thereby, said secon turntable constituting an assembly comprising a block provided with means on one side thereof for frictionally engagingsaid spindle and bearing means on another side thereof for rotatably mounting the turntable, driving means associated with said second turntable, a motion picture projector, a driving means therefor and a driving connection between said. projector driving means and said second turntable driving means.
3. In combination, a talking machine having a rotary spindle provided with means for selectively mounting each of two turntables, one of said turntables having means for engaging said spindle to be driven thereby, the other of said turntables constituting an assembly comprisin means for frictionally engaging said spin e andbearing means on said frictionally engaging means for rotatably mounting said other turntable thereon, a picture projector, a driving means therefor and a driving connection between said projector driving means and said other turntable. In testimony whereof, I have signed my name to this specification this 15th day of Uctober, 1926. 7
