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.
