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. An upstanding first class lever has its vertical midportion pivotally attached to the upper base ends of the tongue arms, its lower end portion pivotally attached to one handle end and the upper end of the lever projects above the upper portion of the C-shaped spring handle.
