DISTANCE METERING DEVICE Russian patent published in 1995 - IPC

FIELD: geodetic instrumentation engineering. SUBSTANCE: device has metering tape 1 with holes 2, case 3 with base 4, frame 5 with supporting prism 6, base support 7 with sight 8, slot 9 for fixing case base, dowel pin 10, lock 11 and fixing screw 12, basing element 13 with carriage 14, balancer 15 with weight 16 and sight 17, level 18, micrometer tensioning screw 19, and indicator 20. EFFECT: provision for metering lines of any length due to use of tape 1 with holes 2 as working flexible metering gage since this tape is set of great number of end gages; improved measurement accuracy and capacity due to use of tapes made of different materials requiring different tensioning. 2 cl, 2 dwg
