Abstract

320,361. Wimperis, H. E., and Elphinstone, Sir G. K. B. July 10, 1928. Accelerometers.-An instrument for measuring inclinations, accelerations &c., of the kind described in Specification 20231/09 comprises two eccentrically pivoted masses the pivots of which are in the same plane and the centres of gravity on opposite sides thereof, and equal distance there from, the pivots being geared together so that the apparatus is effected only by inclinations and accelerations in a plane parallel to that containing the pivots. The masses comprise nuts 8, 9, Fig. 2, on pins 10, 11 attached to discs 23, 24, mounted on,pivots 14, 15 geared together and provided with centering springs 19, 20. One of the .discs 14 carries an indicating hand 25. As shown in Fig. 1 two such apparatus are mounted in a casing 1, one of which carries a hand 26 to indicate the actual inclination while the other carries a hand 25 combined with a ratchet gearing to indicate the maximum inclination in a given period. In a modification a single system of eccentric masses are provided with two indicators one of which is provided with ratchet means for indicating maximum inclination. Magnetic or other damping means may be provided.
