A tape measure for measuring the distance between a first point and a second point. The tape has a flexible, elongated blade. The blade has a plurality of sets of markings and numbers imprinted thereon which correspond to units of measure. The first set of markings consist of true-size indicia for measuring true distances. The second and subsequent sets of markings consist of indicia divided at increments thereon to be utilized for measuring distances directly from drawings prepared at a reduced scale. The tape measure provides a single tool for measuring distances from reduced scale drawings without making calculations and also for measuring true-size distances in construction layout. Construction errors and delays are reduced through the use of this combination device.
In combination, a measuring tape having a scale for measuring distances at a true size and a scale for measuring distances at a reduced scale, said scale for measuring distances at a true size comprising a series of measurement markings whose spacing is indicated by indicia adjacent said markings which give the actual spacing of said markings in a scale of measurement, said scale for measuring distances at a reduced scale comprising a series of markings whose spacing is indicated by indicia adjacent said markings which give the reduced scale spacing of said markings in a reduced scale of measurement, whereby said reduced scale markings are used for measuring distances from construction drawings prepared at a reduced scale and said true-size markings are used for measuring true distances in actual construction, eliminating calculations and reducing errors.
In a coilable, retractable tape measure comprising a measuring blade and a housing having true-size indicia imprinted on one side of the measuring blade, the improvement wherein at least one set of reduced scale indicia are imprinted on an opposed side of said measuring blade, said scale for measuring distances at a true size comprising a series of measurement markings whose spacing is indicated by indicia adjacent said markings which give the actual spacing of said markings in a scale of measurement, said scale for measuring distances at a reduced scale comprising a series of markings whose spacing is indicated by indicia adjacent said markings which give the reduced scale spacing of said markings in a reduced scale of measurement, whereby said reduced scale markings are used for measuring distances from construction drawings prepared at a reduced scale and said true-size markings are used for measuring true distances in actual construction, eliminating calculations and reducing errors.
