Abstract: A stringing tool for a racket, such as a tennis racket for example, provided with individual strings for the net-like interlacing stringing covering the open area of the racket frame, each individual string being anchored at both ends, for example, by a collapsible anchoring clip disposed in a stringing aperture through the racket frame. The stringing tool comprises a pair of jaws for grasping the end of the string projecting beyond the racket frame, the jaws being mounted on a slide coupled to a second slide movable by lever action. The coupling between the two slides has an adjustable releasable mechanism operable to disconnect one slide from the other upon exerting a pull of a pre-determined force on the string. The stringing tool is preferably further provided with a clipper for cutting off the portion of the string projecting from the side of the racket frame after the string has been stretched taut from one side of the frame to the other and securely anchored by the clips in the frame stringing holes.

Abstract: An apparatus and method for folding and crushing empty cylindrical cans such that after being folded and crushed the can end faces are essentially coplanar. The apparatus comprises a flat stationary anvil and a flat parallel reciprocable platen defining therebetween a folding compartment into which an empty can is inserted, an independently reciprocable creasing element or plunger slidably inserted in an aperture through the center of the reciprocable platen such as to enter and leave said folding compartment, and a drive arrangement simultaneously advancing the reciprocable platen and reciprocable creasing element into said folding compartment towards the can, the creasing element being advanced more rapidly than or ahead of the platen, and drive retracting the creasing element after the creasing element has nearly passed through the can without stopping the advance of the platen, and subsequently retracting the platen.
