Description

Watkin brass clinometer 1892, showing close-up of the micrometer drum. The instrument measures approx 6 x 4 x 2 in. Further information is given here, where it says that:

" This instrument was used for measuring and laying out angles. The sensitive bubble level is held between pivots and connected to a lever which is held against the underside of the micrometer drum by a spring. The bronze frame has two surfaces at right angles enabling any slope between 0 and 90 degrees to be measured, between 45 and 90 being accomplished using the upright face and subtracting the angle read from 90 degrees. With it on the surface to be measured, the micrometer drum is rotated to bring the bubble to the centre of the tube. The angle is then read from the drum against the index mark on the collar. It is divided to five minutes of arc. (In the late 19th century) Watkin clinometers were used by the military for checking the elevation of gun barrels."
