Abstract
317,687. McLean, C. C. Nov. 20, 1928. Bases for posts.- Relates to tennis net posts of the type comprising a horizontal base plate formed with an integral socket and a groundengaging blade, and consists in arranging the blade 20, Fig. 3 in the axial plane of the socket 15 and forming the base plate of two oppositely extending flanges 18, 19 of the same width as the top of the blade. In the construction shown in Fig. 3, the flanges 18, 19 and the blade 20 are of substantially triangular shape. Fig. 4 shows a modification in which the blade 36 is in the form of a spade, the flanges 35 have their edges level with the base of the socket, and reinforcing ribs 38 are provided for the blade. In a further modification, one of the flanges 35 may be extended beyond the base of the socket. The post may be tubular or solid and of metal or wood, and is threaded into the socket and secured by a pin 17. A straining pulley 28 for the net cord is provided at the upper end and turned by a crank arm, a pawl and ratchet device holding it in the tightened position. The foot rope is passed through a hole 22 in the socket and knotted at the free ends.
