Abstract
A toy doll having arms which move in response to the upper torso of the doll being pivoted about a horizontal axis. As the upper torso of the doll is tilted back and forth, a pin engaged to the lower torso of the doll slidably engages the upper curved surfaces of a cam support mounted in the upper torso causing a forked plate rotatably mounted on the support to rotate back and forth. Rotation of the forked plate causes a crown gear to rotate which engages two gears with detents rotatably mounted on a shaft. As a result, the two gears with detents rotate in opposite directions causing arm connectors attached to the doll's arms to also rotate in opposite directions. As such, the doll's arms move back and forth in opposite directions as the upper torso is tilted back and forth. A spring disposed around the shaft and between the two gears with detents allows the two gears to disengage from the arm connectors preventing damage to the doll when the arms of the doll are twisted improperly by a child.
