Title: Improvements in self levelling compartments for aerial or marine vessels
IPC: G01C19/44
Filed: 1920-05-05
Abstract: 168,628. Henry, L. I. May 5, 1920. Self-levelling apparatus. -A selflevelling compartment for aerial or marine vessels is mounted on axes which are parallel to the longitudinal and transverse axes GL and GT of a vessel, and rotation about these axes is prevented by a stabilizing-apparatus. Yawing movements about the axis GV are not considered. The stabilizing- apparatus, Fig. 2, comprises a pendulum 4 pivoted at 3 and carrying two rods 4<1>, 4" at right-angles, each having a pair of toothed sectors 2, 2' and 2<11>, 2<111>. The toothed sectors are carried by radial rods which are rotatably mounted in sockets in the rods carried by the pendulum. The sectors engage with four pinions 1, 1<1>, 1<11>, 1<111>, the axes of which are fixed relatively to the vessel, so that pitching or rolling movements of the vessel cause rolling movements of the pinions over the sectors. Relay mechanism is provided by which the rotation of the pinions produces a corresponding reverse rotation of the axes carrying the self-levelling compartment. In one construction, which is shown in two parts in Figs. 5 and 5a, the shaft 15 carries by means of arms 16, 21, and 22 a platform 23 which is to be maintained horizontal. An outer ring 24 is carried by trunnions 44 at right-angles to the axis of the shaft 15 and supports another horizontal platform 30. The two platforms are superposed on one another and are separated by conical roller bearings so that a slight relative rotation is possible during rolling and pitching movements. The two shafts at right-angles, namely, 15 and 44, carry pulleys 20, 27 which are operated by motors controlled by the stabilizing-pendulum. In a modification, Fig. 8, the platform 41 is carried by a shaft 45<1> supported in bearings 34, 35, which are carried by an endless cable 36. The cable is moved by a motor 40 around an axis which is at right-angles to the axis 45<1>.
