Abstract

14,671. Knowles, E. M. Oct. 18. Clinometers comprise a spirit level d mounted on the diametrical cross-piece e of a graduated part-circle c pivoted upon a bracket b attached to a straight-edge a. The periphery of the circular member is provided with teeth f engaged by a pinion g actuated by a milled head h. Through a curved slot in the brackets, the circular graduations can be seen and read against a stationary vernier scale upon the edge of the slot. A magnifying-glass k mounted on a telescopic arm l may be provided.
