Abstract

429,034. Racket-stringing apparatus. JAFFE, W. E. B., 88, Elm Park Road, Chelsea, London. Nov. 23, 1933, No. 32803. [Class 132 (ii)] In a racket-stringing machine wherein the racket frame is held during stringing by a plurality of abutments forced into engagement with its periphery, the abutments are detachably secured to plates pivoted on arms of levers pivotally mounted to the racket frame supporting head, the levers being angularly displaced by a screw, or equivalent. The racket b is positioned on a pivotal supporting head a by abutment pins c housed in holes e<1> in plates e, Fig. 4, pivotally mounted at f<2> to levers f pivoted at g<1> to the head a. The levers f are arranged in pairs and engaged by the ends of cam screws h which when screwed into lugs g2 integral with the head a rotate the levers to force the abutments c into engaging position. The handle end of the racket frame b is engaged by a single pin c on a radially sliding plate i screwed to a guide l adjustable by a nut m. The sides of the racket are also engaged by external abutments comprising bars o rotatably mounted on screws p threaded into the head a, and having cranked ends n for abutting against the racket and convex ends n<1> for bearing against screws secured in frame brackets a<1>. The abutments and their adjusting mechanism may be mounted on conjoint displacing means as described in Specification 332,920, [Class 132 (ii)].
