Patent ID: 8458921

Claim:
An insulation work tool comprising: a rigid, substantially rectangular tool having a front side and a back side; a first indicia on the front side of the tool indicating distances as measured from a first side of a plurality of lines extending from the plurality of lines to a point at the end of the tool, the first indicia referencing a first chart on the back side of the tool, the chart providing a plurality of correlating indicators of the first indicia with respect to a thicknesses of standard insulation that is appropriate for use with certain thicknesses of pipe; a second indicia at a second end of the plurality of lines that refers to pipe sizes as measured from one of the plurality of lines to the point and used with at least one desired pattern; a second chart disposed on the back side of the tool that includes the first indicia and correlates the first indicia to at least one of dimensions of bands, sheet metal, and circumference of insulation listed in the first chart; and, an elongate flat extension, the elongate flat extension having parallel front and back sides, the elongate flat extension being mechanically pivoted at its end with the end of the work tool, the elongate flat extension further comprising: an extension of the first indicia, the second indicia, the plurality of lines and distances so as to extend the range of measurements covered by the first and second indicia; a third chart with at least four different measurements for each of the first indicia, each said first indicia having a number indicating the order, said first indicia and number being pre-measurements of a tee pattern; and a correlation index correlating common sizes of pipe radii with corresponding circumferences.
