摘要： A meridian indicator comprising a base plate, an inclined plate disposed at a selected angle to the base plate, an hourly graduated arcuate plate, means rotatively supporting the arcuate plate upon the inclined plate, a rectangular style plate, means supporting a first edge of the style plate at a selected angle to the inclined plate, means angularly displacing the style plate at a selected angle relative to a horizontal plane, a weighted string means attached to a second edge of the style plate which is parallel to the first edge, aperatures in the inclined plate and the arcuate plate positioned so that weighted string means adjustably passes therethrough, and a latitude scale means deposed on the inclined plate and juxtapositioned to the weighted string means as it passes through the aperatures, an equation of time correction scale means disposed upon the arcuate plate, and a longitude scale means disposed upon the inclined plate in juxtaposition to the equation of time correction scale means, the arcuate plate having hourly graduations so that when a third edge of the style plate is pointing to true north, the shadow of the sun of the third edge of the style plate falls correctly upon an hourly graduation upon the arcuate plate to read true solar time.

摘要： A SUNDIAL COMPRISING A BASE ADAPTED TO BE VERTICALLY DISPOSED AND HAVING AN INCLINED MOUNTING SURFACE, A PIVOT MOUNTED ON SUCH SURFACE AND AN ARCUATE DIAL PLATE ROTATABLY MOUNTED ON THE PIVOT. A STYLE PLATE IS MOUNTED AT AN ANGLE TO THE SURFACE AND HAS TWO PARALLEL SHADOW CASTING EDGES, ONE FOR BEFORE NOON AND THE OTHER FOR AFTERNOON, SPACED BY A SELECTED DISTANCE SO THAT THE SHADOW OF AN EDGE UPON THE ARCUATE DIAL PLATE CAN INDICATE TIME. THE ARCUATE DIAL PLATE HAS APPROXIMATELY EQUALLY SPACED HOUR-MARKS GRADUATED ON A FIXED RADIUS FROM THE PIVOT. A "LOCATION" CORRECTION SCALE IS FIXED

TO THE SURFACE ADJACENT TO THE EDGE OF THE ARCURATE DIAL PLATE. THE DIAL PLATE HAS "SEASON" CORRECTION REFERENCE INDICIA FOR SELECTIVELY SETTING THE DIAL PLATE WITH RESPECT TO THE "LOCATION" CORRECTION SCALE.
