Abstract: A panel of thin bendable material is provided and includes one marginal portion thereof for disposition adjacent the worn side of a journal bore in a clock frame plate with the panel disposed parallelly in juxtaposition with one side of the plate. The aforementioned marginal portion of the panel includes a narrow elongated lengthwise outwardly projecting tongue disposed generally normal to the panel for reception in the worn side of the bore. The tongue is concavo-convex in cross section with the convex side opposing and seated against the worn side of the bore and the concave side of the tongue opposing the side of the bore remote from the worn side thereof. The tongue, therefore, defines an insert for renewing the worn side of the bore and against which the corresponding clock component shaft portion may be journaled.

Abstract: A body is provided defining a center axis and having at least four adjacent sides equally spaced from and about the center axis and disposed normal to adjacent 60.degree. relatively angularly displaced radii of the center axis. Each of the sides includes opposite ends and at least the center two sides of the four adjacent sides are interrupted centrally intermediate their opposite ends by a pair of spaced torque transfer surfaces spaced apart generally one-third the length of the corresponding side and equally from the opposite ends thereof. The surfaces are disposed on radii of the center axis. In a first form of the invention only four of the adjacent sides are provided and the end two or remote sides of the four adjacent sides are free of the aforementioned transverse surfaces and the sides face inwardly toward the center axis of the body.
