Calipers arranged for remote reading

Abstract

The invention is an improved calipers that is arranged for reading at a remote distance from the object being measured, for either inside or outside diameters. The need for a calipers capable of being read at a remote distance is experienced when an item to be measured, such as a pipe, is below ground level in a manhole or drain catch basin, or at some elevated location above ground or floor level that is not readily accessible. The present invention of a calipers eliminates climbing down into a manhole or a drain opening where a ladder may be absent or not readily available or where dangerous gases may be present, or at an elevation above floor or ground level when a ladder is not readily available. The invention consists of a pair of sliding rod members to define the dimensional reading, a pair of dimensional point indicators, a plurality of sliding rod combined coupler-guides, and a plurality of affixing members for connections. The sliding rod members may be in a plurality of sections.
