One-point control selective phonograph apparatus

Claim 1

IN A PHONOGRAPH APPARATUS, A FRAME, A PHONOGRAPH RECORD REVOLVABLY MOUNTED ON THE FRAME, AN ELECTRIC MOTOR WITH MEANS ARRANGED TO TURN SAID RECORD WHEN SAID MOTOR IS ACTUATED, A PICK-UP ARM COMPRISING A SPRINGY STRIP ELEMENT SWINGABLY MOUNTED AT ONE OF ITS ENDS ON THE FRAME, FOR MOVEMENT ACROSS THE RECORD AND A MEANS INCLUDING A STYLUS ASSOCIATED WITH A DIAPHRAGM AT THE OTHER END OF SAID STRIP ELEMENT, ADAPTED WHEN THE RECORD IS TURNING AND SAID STYLUS IS IN CONTACT WITH A SOUND GROOVE ON THE RECORD, TO TRANSLATE VIBRATIONS OF THE STYLUS INTO SOUND; SAID STRIP ELEMENT BEING BIASED SO THAT SAID STYLUS NORMALLY CONTACTS THE RECORD, AN ELECTRICAL SWITCH MECHANISM INCLUDING A DIELECTRIC MEMBER FIXED ON THE FRAME, CARRYING A PREDETERMINED NUMBER OF CONDUCTIVE ELEMENTS IN SPACED RELATION THEREON, CONDUCTIVE MEANS CONNECTING SAID CONTACT ELEMENTS AND CONSTITUTING ONE TERMINAL OF SAID SWITCH MECHANISM, A CONDUCTIVE FINGER CONSTITUTING THE OTHER TERMINAL OF SAID SWITCH MECHANISM, EXTENDING FROM SAID STRIP ELEMENT; SAID FINGER BEING ADAPTED FOR WIPING CONTACT WITH ONE OF SAID CONTACT ELEMENTS AT ONE TIME AT ANY POSITION THE STYLUS MAY BE ON THE RECORD BEFORE IT REACHES THE END OF THE RECORD AND AS SAID PICK-UP ARM MOVES TO BRING THE STYLUS TOWARDS THE END OF THE RECORD, TO TRAVERSE SAID ONE ELEMENT, AN ELONGATED OPERATOR MEMBER POSITIONED SUBSTANTIALLY PARALLEL TO THE AXIS OF SWING OF SAID PICK-UP ARM; SAID OPERATOR MEMBER BEING MOUNTED FOR LATERAL MOVEMENT ALONG A DEFINITE PATH ON THE FRAME, AN ELEMENT EXTENDING FROM SAID OPERATOR MEMBER SO THAT PART OF SAID ELEMENT IS SPACED FROM AND ALONG SAID OPERATOR MEMBER; SAID FINGER BEING BETWEEN SAID OPERATOR MEMBER AND SAID ELEMENT PART SO THAT UPON MOVEMENT OF SAID OPERATOR MEMBER ALONG SAID PATH, THE FINGER WILL BE MOVED TO CAUSE THE PICK-UP ARM TO SWING, MEANS TO RELEASABLY HOLD SAID OPERATOR MEMBER AT PREDETERMINED POSITIONS ALONG SAID PATH; SAID POSITIONS BEING SO SPACED THAT WHEN SAID OPERATOR MEMBER IS AT ANY ONE OF THEM AND SAID FINGER IS IN CONTACT WITH SAID OPERATOR MEMBER, SAID FINGER WILL CONTACT A PARTICULAR ONE OF SAID CONTACT ELEMENTS RESPECTIVELY; SAID OPERATOR MEMBER BEING CAPABLE OF LONGITUDINAL MOVEMENT, CAM MEANS ON SAID OPERATOR MEMBER, ADAPTED UPON LONGITUDINAL MOVEMENT OF SAID OPERATOR MEMBER IN ONE DIRECTION, TO BEND SAID SPRINGY ELEMENT SO THAT THE STYLUS LEAVES THE FACE OF THE RECORD AND TO SET SAID FINGER INTO CONTACT WITH SAID OPERATOR MEMBER; SAID FINGER BEING MOVABLE BETWEEN SAID OPERATOR MEMBER AND THE MENTIONED ELEMENT PART; THE SPACE BETWEEN SAID OPERATOR MEMBER AND SAID ELEMENT PART BEING SUCH THAT UPON MOVEMENT IN SAID SPACE FROM CONTACT POSITION WITH ONE TO CONTACT POSITION WITH THE OTHER, SAID FINGER WILL TRAVERSE ONE CONTACT ELEMENT, AND A CIRCUIT FOR ACTUATING SAID MOTOR, INCLUDING SAID SWITCH MECHANISM TO CONTROL MOTOR OPERATION.
