Abstract: A flipper game having a plane-sloped playing plate arranged in a housing on which obstacles for the run of the ball are arranged. The ball enters at the head end of the playing plate and runs in the direction of the slope down to a target opening arranged at the foot end of the playing plate. The slope of the playing plate can be regulated thereby altering the running velocity of the ball for production of varying degrees of difficulty. The slope of the playing plate can be manually set or incremented automatically depending on the score.

Abstract: A coupling unit includes a pair of parts, mounted on respective panels, each on an axis extending through the panel. The panels are moved into coupling position, with the parts thereby in interconnecting position, with elements of the parts interlocking, and their axes coincident. The two parts are then rotated on their common axis. Two units are used together, in spaced apart relation. In one form of the device, the parts of each unit are identical, and in another form, they are respectively of male and female shapes.

Abstract: A winch includes a spindle plate having a plurality of pins fixed thereon, the pins forming the core of a winch and the line of the trap is wound on the pins. An ejector plate is axially slidable for ejecting the wound line from the pins into the water. The space surrounded by the pins forms a basket in which the buoy is put in the winding-in step, this securing the line to the pins for the winding. The ejection step is produced by a slidable ejection shaft carrying the ejection plate, and driven by a motor. An advancing shaft is carried by and within the ejection shaft, and at the final movement of the ejection shaft, the advancing shaft ejects the buoy clear of the line coil. The advancing shaft is moved relative to the ejection shaft, by a cam carried by the ejection shaft and engaging a fixed trip unit.

Abstract: A tube having an open front end and a piston therein. The piston is moved manually to a forward cocked position adjacent the open end of the tube, against the action of a tension spring. A closure flapper is hinged in the tube adjacent the open end of the tube, spring biased to closed position. In operation, the open end of the tube is held near the insect, with the piston in cocked position, and the piston is then released, which is thereupon drawn back by the tension springs. This movement of the piston produces a vacuum in the tube, this action opening the closure flapper, and drawing in the insect, after which the closure flapper is moved to closed position by the spring.
