Abstract
414,424. Tennis &c. practising- appliances. KUM-BAK SPORTS TOYS & GAMES MANUFACTURING CO., Ltd., and LAKE, P., 154, Vauxhall Street, London. Feb. 9, 1933, No. 3984. [Class 132 (ii).] In a tennis or other ball game practising- appliance, a ball is suspended by a cord from an arm adapted to rotate continuously, but in one direction only, about an axis substantially transverse thereto. In one embodiment, the ball is attached to an elastic cord 24, Fig. 1, connected by a swivel clasp 22 to a flexible inextensible cord 23 connected by a swivel clasp to a resilient tube 14 attached by a bayonet joint 13 to a standard 11, mounted on a cruciform base 1 by means of a known type of free-wheel bearing comprising ball races 3, 4 and a ratchet mechanism 6. Alternatively, the tube 14 may be coupled to the standard 11 through a spiral spring, or it may be mounted thereon for axial rotation. In another embodiment, the ball races 3, 4 and the ratchet mechanism 6 are mounted at the top of a fixed standard 11, Fig. 2, an arm corresponding to 14 being sleeved over springs 33 rotatably mounted on the block 26 by means of a ball bearing 5.
