Abstract: Apparatus for practicing and teaching ball batting characterized by use of a rotary member journaled for rotation about a shaft, and a flexible linkage affixes a ball, nominally a baseball, in a down-hanging position from the rotary member. When the ball is struck with a bat it will move in an arcuate motion about the axis of the rotary member. Particularly in accordance with the present invention, a backboard mounts the rotary member to a vertrical post. The backboard is releasably maintained upon the post by "U" bolts which hold the post against a channel formed by spaced-apart parallel spacer bars positioned upon the backboard. The flexible linkage incorporates a spring-biased hook allowing ready substitution of balls thereon.

Abstract: A multiposition rotary transformer switch including a molded switch housing including a bore, an interrupted mounting flange located intermediate the ends of the bore and an interrupted key flange at one end of the bore, the flanges each including slots located at equally spaced intervals, the slots in one flange being offset from the slots in the other flange and a number of fixed contacts mounted on said housing, a dual voltage shaft assembly including a shaft having a drive nut at one end and a pair of floating contacts at the other end, and a tap changer shaft assembly including a shaft having a drive nut at one end and a floating contact at the other end, the shaft assemblies being adapted to be mounted in the bore in the housing and a reversible cap adapted to be mounted on the switch housing to enclose the end of the shaft assemblies in one position and mounted on the drive nut on the shaft in the other position to selectively rotate the shaft assembly with respect to the fixed contacts, the cap being

Abstract: A carrying bag or tote bag to the exterior sides of which is removably attached a flexible wrap-around element which, on its exterior surface, is impressed or otherwise applied the design of a game board, or the like. The wrap-around element can be detached from the bag and extended flat on a suitable plane surface to form a game board upon which the game can be played. The design of the game board on the wrap-around element serves also as a decorative feature of the bag.
