Abstract
A measuring apparatus for determining dimensional data for use in designing a coupler which is manufactured to be fitted between the free ends of already assembled pipes in a pipe system is disclosed. A first joint on which a first arm is slidably supported is pivotally connected to one end of a rod adapted for gauging the distance between the points of bend in the coupler to be manufactured. A first joint on which a second arm is slidably supported is itself slidably mounted on the rod for movement therealong. With this arrangement, measurement of the angle defined by relative rotation of the rod about its axis to the arms is limited to one point, that is, at either of the joints. In addition, this apparatus permits easy installation on the site of measurement. The relative movement between the rod and the second arm and that between each arm and its associated attachment plate for engaging to the respective free end, are automatically measured by an electrical detection device.
