Abstract: The rack permits a single player to play a large number of bingo cards in every game, and without preempting more than his fair share of table space. The rack has a multiplicity of long horizontal rods extending from the player's left to right and supported by a pair of end frames, for instance 4 or 5 such rods, parallel to each other. The rod nearest the player is closest to the table, and is spaced above it a little more than the thickness of two bingo cards. This same spacing is used between rods, i.e., a staircase spacing with the same spacing of the second rod both above and behind the first rod, etc. The bingo cards are mounted in back-to-back pairs in special clips mounted on the rods and pivotal between a vertical position and a horizontal position, reading one card of a pair in each position. Each clip has portions defining a pocket which has an open top and one open side, so that a marginal portion of the pair of bingo cards is received in the pocket.

Abstract: A pigeon trap including a two-level walkway and a locking mechanism barring entry of animals such as house cats and other predatory quadrupeds of comparable size. The upper level walkway is or is covered by a hinged deck plate which remains in a tilted, off-horizontal position as long as there is no weight on it, and in this position it exerts an upward force on one end of a pivoted balance beam through a rod connecting the two members. This causes the opposed end of the balance beam to be depressed, thereby freeing the lower ends of the pivotally mounted bobs which would otherwise be locked in place by the balance beam. In this position of the members, a pigeon standing on the lower level walkway can push the bobs out of his way and fly into the loft.

Abstract: An illuminated sign panel adapted for mounting on the sides of vehicles such as trucks and having removable and replaceable sign display areas in the form of sheets of transparent or translucent materials. A sign display area may be composed of one sheet or several. The illumination is indirect and is designed to be supplied from behind the sign display area. The display panel is rigidly and fixedly mounted on the vehicle which can be an automobile, panel truck or truck trailer, for example.
