Abstract

117,161. Gaynor, T. F. Aug. 3, 1917. Clinometers.-A universal clino. meter for use with aircraft, submarine and other ships, railway vehicles, &c., comprises a plummet which keeps a vertical position in a transparent spherical vessel filled with liquid, but has no fixed connexion with the vessel. The piummet consists of a glass tube A<1>, Fig. 4, provided with a weight A, an air space A<7>, and a plug A'. The plummet is either heavier or lighter than the liquid and rests in contact with the bottom or top of the container. The vessel C has an opening closed by two plugs, between which is an air space to allow for expansion of the liquid, and is gripped elastically in a casing G<1>, G<2> formed with observation openings fitted with adjustable indicator cross-bars and a graduated dial. The plummet is illuminated by one or more electric lamps L shining through sheets J<14> of translucent material, or is rendered self. luminous by luminous paint or radioactive material. Fig. 8 shows an arrangement in which the image of the plummet in a mirror N is also seen, so that its inclination in two directions can be observed simultaneously. Fig. 17 shows an horizontal disk D fitted to the plummet to indicate by its apparent shape the inclination to or from the observer. The two sides of the disk may be differently coloured. The edges of the disk and the bottom of the plummet may be arranged to make contact with plugs T, T<1>, T<2> placed in the circuit of an electric signalling or controlling device. An air bubble in the vessel C may act as a level indicator, or a spirit level may be arranged in a lateral extension of the vessel. Any vibration in the structure to which the clinometer is applied assists the plummet in taking up a vertical position, when the inclination is altered. In order to obviate the effects of centrifugal force, a weight may be placed at the upper end of the plummet below the plug A<5>. A magnetic needle may be attached to the disk D to act as a compass.
