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.
A repair journal for a worn shaft journal bore in a clock frame plate, said repair journal comprising a panel member for support from one side of said plate in parallelly juxtaposition thereto, said panel member including a marginal portion thereof for disposition adjacent the worn side of said bore, said marginal portion of said panel member including a narrow laterally projecting tongue supported therefrom adapted to project into said worn portion of said bore, said tongue being transversely concavo-convex with the convex side thereof adapted to at least substantially seat in said worn side of said bore and the concave side thereof being adapted to oppose the side of said bore remote from said worn side, at least one portion of one side surface of said panel member including an adhesive coating, whereby said panel member may be adhesively secured to one side of said frame plate.
In combination with a clock frame plate including a shaft journal bore formed therethrough having at least one radially outwardly enlarged worn peripheral portion, a repair journal for said bore comprising a panel member mounted from said plate and overlying one side thereof in parallelly juxtaposition thereto, said panel member including a marginal portion thereof disposed adjacent said worn peripheral portion, said marginal portion of said panel member including a narrow laterally projecting tongue supported therefrom projecting into said worn peripheral portion, said tongue being transversely concavo-convex with the convex side thereof at least substantially seated against said worn peripheral portion and the concave side thereof opposing and coacting with the side of the journal bore opposite the worn peripheral portion thereof to restore the journal bore to substantially its original size.
