Abstract

693,317. Making bolt-hole bushes. ROSAN, J. March 13, 1951, No. 6074/51. Classes 83 (i), 83 (ii) and 83 (iv). [Also in Group XXV] Casting composite articles; building up articles by spraying.-To permit the removal of a screwed insert from a casting, and its subsequent replacement by a new one, the insert is protected from bonding with the cast metal by a shell 21, Fig. 1, helically corrugated to fit the coarse retaining thread 2 on the insert by using the latter as a mandrel. The shell has a flange 24 that fits a frusto-conical surface beneath the head of the insert. The head is longitudinally serrated at 6 to prevent rotation. In a modification the shell is formed by spraying metal on the insert, which is coated where it is desired to prevent adhesion. In a further modification the protector is formed from bar stock, the end being closed by a plug 47, Fig. 8.
