Abstract

The device consists of a sleeve (1) on which are pivoted two arms (3, 3a) with extensions of soft material such as lead. Within the sleeve (1) is a rod (8) with a stop (7, 8) at each end. A coil spring (9) is fitted between the end of the sleeve and one of the stops (8). The sleeve with its arms parallel to its length is introduced to the space to be measured. Pressure is maintained on stop (8) and the sleeve rotated so as to extend the arms by centrifugal force. The lower stop (7) locks the arms (3, 3a) perpendicularly to the sleeve (1). By moving the piston to TDC the lead is compressed to give an imprint.
