Abstract

Abstract A toy phonograph of the type wherein one of several record tracks to be played is determined by the initial rotational position of the turntable when it begins rotating in a forward direction, in which the mechanism for determining the initial turntable position includes a pawl arm fixed to the turntable and several detents spaced around the turntable that can prevent reverse rotation of the pawl arm past a selected position. A mechanism for assuring that only one of the several detents are at an inward position to engage the pawl at any tine, includes a steel band encircling the pawl arm and engaged with the detents, and positioners that hold the band so the band is ''''puckered in'''' at one location to hold a detent inwardly at that location. When another detent is pushed in so it ''''puckers in'''' another band location, any detent which was inward is automatically moved out.

Claim 2
Dependent Claim 177 words
A phonograph apparatus comprising: a turntable; a record mounted on said turntable, said record having a plurality of record grooves with circumferentially spaced leadin portions; playing head means including stylus means for playing the record groove whose leadin portion lies at a predetermined circumferential position as the turntable begins rotating in a predetermined forward direction; means for urging said turntable to rOtate in a reverse direction and then in said forward direction at each record playing; and selecting means coupled to said turntable for preventing reverse rotation thereof past a predetermined rotational position, including a plurality of detents circumferentially spaced about the axis of rotation of the turntable, pawl means connected to the turntable for engaging a detent to prevent only reverse turntable rotation past the detent, said detents being movable into and out of a position to engage the pawl means, and retracting means coupled to said detents for moving any detent which is in a position to engage the pawl means out of that position when another detent is moved into a pawl meansengaging position.
Claim 3
Dependent Claim 81 words
The apparatus described in claim 1 wherein: said retracting means includes an elongated flexible member which strongly resists stretching, extending about the axis of rotation of the turntable, and a plurality of locating means spaced from one another along said member for confining regions of said member against deflection toward or away from the axis of rotation of the turntable, said detent means engageable with said flexible member at positions between said locating means for locally deflecting said flexible member inwardly.
Claim 4
Dependent Claim 26 words
The apparatus described in claim 2 wherein: said elongated member is constructed of resilient material and is coupled to said detent means to move them outwardly.
Claim 5
Dependent Claim 63 words
The apparatus described in claim 1 including: a toy housing substantially enclosing said turntable; a plurality of manually movable members mounted on said toy housing; and a plurality of means connecting said manually movable members to said detents, so that a predetermined movement of one of said movable members causes a corresponding detent to move into a position to engage the pawl means.
Claim 6
Dependent Claim 152 words
In a phonograph which includes a record-supporting turntable, a playing head which plays a selected one of several tracks of the record in accordance with the initial rotational position of the turntable when it begins turning in a forward direction, and means which urges the turntable to rotate in a reverse direction before it rotates forwardly, the improvement of track selecting means comprising: a detent-engaging member connected to said turntable to rotate with it at least in a reverse direction; a plurality of detents spaced from one another about the path of said member, each detent movable into and out of a position to engage said member when the member turns in a reverse direction, to thereby halt reverse rotation of the turntable; and retracting means responsive to movement of a detent into a position to engage the member, for moving any other detent out of a position to engage the member.
Claim 7
Dependent Claim 152 words
In a phonograph which includes a record-supporting turntable, a playing head which plays a selected one of several tracks of the record in accordance with the initial rotational position of the turntable when it begins turning in a forward direction, and means which urges the turntable to rotate in a reverse direction before it rotates forwardly, the improvement of track selecting means comprising: a detent-engaging member connected to said turntable to rotate with it at least in a reverse direction; a plurality of detents spaced from one another about the path of said member, each detent movable into and out of a position to engage said member when the member turns in a reverse direction, to thereby halt reverse rotation of the turntable; and retracting means responsive to movement of a detent into a position to engage the member, for moving any other detent out of a position to engage the member.
Claim 8
Dependent Claim 93 words
The improvement described in claim 5 wherein: said retracting means includes a resilient band extending about the axis of rotation of the turntable and engaged with the detents, a plurality of locating means spaced about the axis of the turntable and supporting portions of the band located between adjacent detents against deflection, said band being constructed of a material that strongly resists stretching, whereby the local bending of the band by a detent causes the rest of the band to move out of a deflected condition and to move any detent with it.
Claim 9
