Abstract: A clamping device for clamping a straight edge to a board to hold such straight edge in place during use thereof. Two clamping members are moveably interconnected to opposite ends of a shaft which extends through an aperture in a bearing member. The bearing member is connected to the straight edge, and the shaft moveably extends through such aperture. The clamping members are provided with locking means, and when such means are operatively locked one clamping member engages and exerts a compressive force against one surface of a board and the other clamping member engages the bearing member to thereby exert an opposing compressive force to lock the straight edge in place.

Abstract: A portable folding crib housed in a suitcase or similar piece of luggage is disclosed. In the basic embodiment, the crib-suitcase combination is so constructed that a majority of the total volume of the suitcase is preserved as two compartments for storing the crib mattress, clothing, and the like. Each of the two compartments is covered by a separate hinged door, the two doors forming the floor of the crib when the crib is erected. The crib structure when folded fits around the storage compartments which are covered by the hinged doors. When folded and closed, the structure has the appearance of an ordinary suitcase and is as readily transportable as the average packed suitcase. To utilize the crib, one fully opens the suitcase and unfolds the crib into its erected position. No mechanical skill or special tools are necessary to unfold or refold the crib. In addition to the basic embodiment, several additional embodiments of the invention are disclosed.
