Abstract
Abstract A musical jack-in-the-box toy which can be operated by pulling it along the ground or by turning a handle, comprising a sheet metal box on a molded plastic carriage. The carriage has walls that form a recess for receiving the sheet metal box, while the box has sidewalls but no bottom wall. In order to prevent inward buckling of the box sidewalls, a bottom wall of the carriage has pins to push the box walls outwardly against the carriage sidewalls. A clutch for coupling the carriage wheels to the music mechanism includes an integral pawl member with a hub and pawls joined by a thin section of material which acts as a hinge.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
107 words
A pull toy comprising: a carriage having forward and rearward ends, said carriage having wheels for supporting it on the ground; a pull string attached to said carriage to move it in a forward direction; a music device mounted on said carriage for operation in a predetermined direction to play music; a handle mounted on said music device for operating it; and a directional clutch for coupling said wheels to said music device to drive it when said wheels are rolling forward and to decouple said wheels from said music device when said music device is driven in said predetermined direction by direct rotation of said handle.
Claim 2
Dependent Claim
107 words
A pull toy comprising: a carriage having forward and rearward ends, said carriage having wheels for supporting it on the ground; a pull string attached to said carriage to move it in a forward direction; a music device mounted on said carriage for operation in a predetermined direction to play music; a handle mounted on said music device for operating it; and a directional clutch for coupling said wheels to said music device to drive it when said wheels are rolling forward and to decouple said wheels from said music device when said music device is driven in said predetermined direction by direct rotation of said handle.
Claim 3
Dependent Claim
70 words
The pull toy described in claim 1 wherein: said clutch comprises a first member with internal ratchets and a second member rotatably mounted within said first member, said second member constructed of polypropylene material and having a hub and a plurality of pawl members radiating from said hub and integral therewith, said pawl members having radially inner ends which are narrowed into a living hinge coupling them to said hub.
Claim 4
Dependent Claim
138 words
A clutch for toy mechanisms comprising: a pawl member having a hub, a plurality of pawls, and a hinge portion integral with said hub and pawls for connecting them, said pawl member constructed of at least partially resilient material and each of said pawls being at least several times thicker than each of said hinge portions so that said pawls pivot substantially only about said hinge portions; and a ratchet wheel with an internal ratchet surface extending around said pawl member, said internal surface of a size to maintain said pawls extending primarily tangentially to said hub, and said internal surface having ledges oriented to urge a pawl in a direction substantially in line with its hinge portion when said pawl member and ratchet wheel are urged to rotate in a first predetermined direction relative to each other.
Claim 5
Dependent Claim
138 words
A clutch for toy mechanisms comprising: a pawl member having a hub, a plurality of pawls, and a hinge portion integral with said hub and pawls for connecting them, said pawl member constructed of at least partially resilient material and each of said pawls being at least several times thicker than each of said hinge portions so that said pawls pivot substantially only about said hinge portions; and a ratchet wheel with an internal ratchet surface extending around said pawl member, said internal surface of a size to maintain said pawls extending primarily tangentially to said hub, and said internal surface having ledges oriented to urge a pawl in a direction substantially in line with its hinge portion when said pawl member and ratchet wheel are urged to rotate in a first predetermined direction relative to each other.
Claim 6
Dependent Claim
154 words
The clutch described in claim 3 wherein: said pawl member and ratchet wheel are mounted for rotation about the same axis of rotation; said internal surface of said ratchet wheel varies in radial distance from said axis of rotation as a function of angular position, so that said radial distance decreases gradually with change of angular position from a first angular position to a second angular position, then increases rapidly from said second angular position to a third angular position, then decreases gradually from said third angular position to a fourth angular position, and then increases rapidly; and said pawl member is formed with said pawls of a length which requires them to be bent about said hinges until they extend substantially tangentially to said hub in order to fit within a circle of a radius equal to the radius of said internal surface of said ratchet wheel at said first angular position thereof.
Claim 7
Dependent Claim
100 words
A wheeled toy comprising: a wheeled carriage having means for moving the same along a supporting surface; a music device on said carriage for operation in a predetermined direction to play music; a handle on said music device for operating it; and a one-way clutch drivingly connecting at least one of said wheels to said music device to operate the same in said predetermined direction when said carriage moves along said surface in one direction, said one-way clutch serving to decouple said music device form said wheel when said music device is driven in said predetermined direction by said handle.
Claim 8
Dependent Claim
100 words
A wheeled toy comprising: a wheeled carriage having means for moving the same along a supporting surface; a music device on said carriage for operation in a predetermined direction to play music; a handle on said music device for operating it; and a one-way clutch drivingly connecting at least one of said wheels to said music device to operate the same in said predetermined direction when said carriage moves along said surface in one direction, said one-way clutch serving to decouple said music device form said wheel when said music device is driven in said predetermined direction by said handle.
