Abstract

523,962. Making posts. BETTLES, J. W. E., and WINN, W. N. Jan. 18, 1939, No. 1683. [Classes 83 (ii) and 83 (iv)] [Also in Group I] Stamping. -Enlargements are produced in tubes for example posts for hand rails by expanding under internal fluid pressure. The part to be expanded is enclosed in a two part die 5 and the tube is plugged on either side of the part at 3, 4, the plug 4 being arranged to admit oil or other pressure fluid. The enlargement is drilled for the rail or for jointing purposes.
