Abstract:
1. A stencil assembly for marking paving required grade levels in a paving operation, comprising: a front plate, said front plate carrying a first array of indicator lines arrayed transversely across a face of said front plate, said indicator lines being uniformly spaced apart one from another, said front plate further carrying a column of numeric measurement numerals centrally located on said front plate, each of said numerals being associated with a curb outside face reveal dimension measurement visable above a paving finish grade level, said front plate carrying a second array of indicator lines disposed on at least one side marginal area of said front plate, each second array indicator line being disposed intermediate succeeding pairs of first array indicator line lengths at said one marginal area of said front plate, said front plate carrying an additional column of numerals at said front plate one side marginal area, said additional column numerals each being associated with at least one of said first array indicator line lengths and said second array indicator lines, said additional column numerals each representing a finish grade thickness; a support member, said support member having a curb engagable flange receivable on a top face of a curb for mounting the stencil assembly in a use position thereof on said curb; a finish grade level indicia carried on said front plate, said finish grade level indicia being located on said front plate a fixed distance below a lowermost indicator line in said first indicator line array, an uppermost indicator line in said first indicator line array being located proximal a top end of said front plate, the numerals in said centrally located column increasing from a least value of said lowermost indicator line to a highest value of said uppermost indicator line; a sub par grade level indicia carried on a back plate proximal a bottom end of said back plate, said back plate having a finish grade level locator marking line disposed on a marginal side area part of said back plate and located proximal a top end of said back plate; said finish grade level indicia and said sub par grade level indicia each comprising openings in said front plate and said back plate, respectively, through which a marking agent can be applied to a curb surface; and means for captively fastening said front plate, said back plate and said support member together with said back plate disposed between said front plate and said support member, a relative positioning between the front and back plates being set to register an indicator line associated with a selected finish grade thickness with said finish grade level locator marking line on said back plate, the front plate then being locked to the back plate with said fastening means, the support member then being adjusted on the back plate to locate said curb engagable flange registered with the first array indicator line corresponding to a column numeral associated with a selected reveal measurement.
