Abstract: A training device for football or other ball games comprises an inextensible net stretched between two opposed side edges integral with rectilinear and semi-rigid members. These members are connected to the uprights of a frame by elastic tensioning members attached to hooks of the frame. The upper and lower longitudinal edges are integral with elastic tensioning members extending from one member to the other. The device facilitates training without having to run after the ball.

Abstract: A ball game to be played in a swimming pool and a tilted backstop for use in the ball game. The backstop, includes a rigid broad board; and a supporting apparatus for supporting the board in a position that is tilted from the vertical at an angle in a range of ten degrees to twenty degrees when the supporting apparatus is placed upon a horizontal surface. The supporting apparatus includes a pair of rods extending horizontally from the bottom of the board in the direction that the top of the board is tilted forward. The forward ends of the rods are bent downward for hooking over the edge of a curb for preventing the board from being thrust backward when the forward broad surface of the board is struck. The backstop is positioned on a horizontal surface against a curb at the edge of a swimming pool so that the forward ends of the rods hook over the edge of the curb.

Abstract: A game apparatus for use with projectiles, such as table tennis balls, including a ball receiving housing having a ball entrance and ball guide apparatus leading to a target area to receive balls propelled toward it by a player or players. Balls arriving at the target area are received by ball propelling apparatus which return or eject the balls toward the player through ball ejection guiding passage apparatus and an ejection opening. The game may be played by a single player for practice or by several players to simulate tennis, table tennis, handball or the like.
