Abstract

904,899. Anchor-bolts. BAYLISS, JONES & BAYLISS Ltd. Aug. 14, 1959 [Aug. 16, 1958], No. 26409/58. Addition to 840,741. Class 89 (1). The anchor-bolt according to the parent Specification is modified by the provision of spring-arms 19 integral with the retaining member body 12 and extending therefrom along grooves 21 in the sleeve parts 10, 11 to hold the sleeve parts together during insertion of the anchor-bolt in a bore 9. Locating lugs 17 may also extend from body 12 and be accommodated in a rebate 18 in the sleeve parts. The arms are fixed to the parts by peening the material at the sides of the grooves into notches in the arms.
