Abstract

872,178. Bolted joints. NAPIER & SON Ltd., D. Jan. 27, 1960 [Feb. 2, 1959], No. 3656/59. Class 83 (4). [Also in Group XXVI] A piston (Group XXVI) comprises at least two separate portions 1, 4 which are formed of materials having different coefficients of thermal expansion and have the adjacent faces of the two portions formed with co-operating surfaces (e.g. V-section ridges and grooves) generated by lines passing through a central longitudinal axis of the structure such that the surfaces co-operate to locate the two portions of the structure against relative displacement of the portions normal to any axial plane while allowing relative thermal expansion between the parts. The parts are connected to one another by anchorage bolts 16, which lie in slightly oversize longitudinal bores 19 and the flexibility of which allows small radial relative displacements between the upper and lower ends.
