Abstract: An educational toy for children including a number of specially shaped blocks designed to be arranged in a side by side relation within a container. Each block has information of an alpha-numeric nature in a particular series on one face and information of a different series on a second face. The toy, when assembled, displays the complete sequential information of the series in rows.

Abstract: An agricultural implement having a wing frame which can be folded up relative to another portion of the frame from a working position to a transport position, and having a hinge connection between the frame which permits the wing frame to float relative to the other frame when in the working position but which readily accommodates pivoting of the wing to the transport position. The hinge connection includes pivot pins which provide a pair of parallel pivot axis so that the floating action of the wing frame is such that the wing frame can pivot about its inner end or in effect move straight up and down relative to the other frame, and thereby provide a motion by way of which the wing readily accommodates uneven terrain. While a type of universal floating action of the wing member takes place when in the working position, a simple type locking mechanism is included in the hinge so as to prevent pivoting about the axis of one of the pins when the wing frame is raised to the transport position.
