Abstract
632,601. Bolts. SULZER FRERES SOC. ANON. July 2, 1947, No. 17471. Convention date, July 3, 1946. [Class 89 (i)] i[Also in Group XXVI] To enable a bolt, that is hollow for the passage of fluid, to be tightened initially to a predetermined stress, it is fitted with a comparator member 1, also hollow to permit the fluid to pass, and permanently secured at one end as by welding at 2. A dial gauge 6 temporarily attached to the bolt at 7 and bearing on the end of the member 1 indicates the stress by measuring the elongation. The member 1 may be screwed into the bolt or may be expanded into grooves in the bore. In a modification the member 1 extends initially beyond the end of the bolt becommg flush therewith when the desired stress has been applied.
