Abstract: An elongated tubular arm of non-circular internal and external cross-sectional shape is provided and has a first elongated transverse jaw carried thereby and projecting outwardly of one side of the arm. The jaw defines a transverse non-circular opening in one end closely slidably receiving the arm therethrough for longitudinal shifting of the jaw along the arm. An elongated operator of non-circular cross-sectional shape is slidingly telescoped in the arm and a first end of the operator projects outwardly of the corresponding end of the arm. A second elongated transverse jaw has one end supported from the operator first end and projects outwardly of the side thereof corresponding to the aforementioned side of the arm in opposition to the first jaw.

Abstract: First and second opposite side pairs of laterally spaced upstanding tong arms defining open sided recesses opening toward each other are provided. The tong arms include upper and lower ends and structure is provided pivotally connecting the upper base ends of the tong arms together for relative swinging of the lower ends of the tong arms toward and away from each other. A downwardly opening generally C-shaped spring handle including remote handle ends is provided and structure pivotally attaches each handle end to a corresponding pair of laterally spaced tong arms intermediate the upper and lower ends thereof for angular displacement of the handle ends relative to the arms about parallel horizontal axes disposed at generally right angles relative to the directions in which the tong arms open, the C-shaped spring handle being disposed in a plane generally paralleling the planes in which the tong arms swing relative to each other.

Abstract: An entertainment and/or educational device is proposed which comprises a housing having oppositely facing windows therein and a display element within the housing having related markings thereon, the individual ones of the said related markings being simultaneously visible through a respective one of the windows and the windows being provided in such disposition on the housing that the respective markings visible thereat can be viewed only from opposite sides of the housing.
