Abstract

244,367. Zeumer, H. Aug. 5, 1925. Locks, permutation, of the kind in which notched rings are separately set to allow a spring-pressed locking-member to release the part locked, are provided with locking rings of a polygonal crosssection with spring-pressed balls mounted in their side faces to hold them in adjusted position. The balls click over recesses preferably on separating washers so that the click produced by the notch in passing the locking-member is masked, preventing picking. The locking-member r is U- shaped and engages recesses in links e and k of the members to be locked. It is held in locking engagement against the spring i by polygonal rings m each of which has a ball t pressed outwards by a spring q into engagement with a separating washer s. When recesses o in the rings are all aligned with the member r the spring i forces it upwards and releases the member k. The washers s have recesses w over which the balls click, the recesses being equal in number to the faces of the rings m. The washers s may be dispensed with, in which case the balls engage the adjacent ring.
