Abstract
584,338. Bolt hole bushes. PHILLIPS, N. Oct. 9, 1944, No. 19354. [Class 89 (i)] [Also in Group XXII] Relates to expansion bolt devices of the kind described in Specification 367,547 and consists in improvements in the expandible socket members described in Specification 437,297. These sockets are usually produced by casting lead and if the fingers be connected only by an annulus at the base there is difficulty in obtaining sound castings with a sufficiently high rate of production. The slots 2 separating the fingers are therefore bridged by webs 3, Fig. 2, connecting the fingers. The webs may vary in thickness in the axial direction or may be discontinuous. In a modification the additional connection is by an external annulus 3b, Fig 6. Instead of projecting, this annulus may be at the outer or inner edge of the fingers. The annulus may be preformed and placed in the mould during casting or may be applied to the socket after casting, but in this case the socket is only strengthened during handling and manufacture is not facilitated.
