According to the invention there is associated with the controlling spring 1 and its supporting rod 6 and the trunnion blocks 7, 7a to which the levers 8, 8a are pivoted and through which the rod 6 extends, means adapted to support the spring and rod in such a manner as to prevent or minimize bending of the rod about the trunnion blocks. As shown in Fig. 1, the supporting means comprises a waisted roller 3 mounted in bearings 4 carried by the upper side of the load-transmitting link 5, the roller bearing against a casing 2 enclosing the outer end portion of the spring. In a modification, the outer end of the rod 6 is slidable in a bearing carried by the link 5 or other member. The invention may also be applied to the shock-absorber described in Specification 468,078 wherein the spring 1 and rod 6 are arranged vertically, the lower end of the rod 6 in this case being held by a bracket against lateral movement. As in the construction described in Specification 436,907, a link or pair of links 11 may be arranged as shown in Fig. 1 to form with the levers 8a a parallelmotion device for preventing relative slipping of the levers 8, 8a.

Title: Pendular sighting device for aerial navigation

Filed: 1929-01-22
Abstract: 327,777. France, State of, Minister of Air, (Assignee of Marie, F.). Oct. 19, 1928, [Convention date]. Plane-trigonometry calculators.-A sighting- device for use on aircraft for determining the angle of drift and the velocity and direction of the wind comprises a horizontal graduated circle a having its zero on the longitudinal axis of the craft and an arc of a vertical circle b which can slide round the circle a, the circles a, b, being universally suspended by members m from a support s secured to the aircraft. The arc b carries slidable sights c<1>, c<2>, and a vertical rod v<1> passing through the centre of the circle a and journaled at its lower end in the arc b has at its upper end a sight v. In using the device the arc b is turned until it is parallel to the apparent direction of movement of objects on the ground, and the drift angle is then read off on the circle a. If the altitude is known the ground speed can be determined by noting the time at which an object on the ground is in line with the rod v<1> and the time at which it reaches the sighting line vc<1> or vc<2>. Then if the air speed is known the wind speed and direction are obtained 'by constructing a vector triangle of which two sides represent air speed and ground speed and the angle between them is the angle of drift: the third side then represents wind speed. A calculating-device which may be used to find the wind speed &c. comprises a chart, Fig. 5, and a superposed transparent circle, Fig. 6. The chart has a number of arcs e<1> - - e<5> struck from a point Q and representing air and ground speeds and a number of lines n<1> - - n<5> radiating from the point Q and representing drift angles. The circle is marked with radiating lines l<1>, l<2> &c., and with circles f<1>, f<2> representing different values of wind velocity. If for example with an air speed of 33 metres per second and the rudder central the ground speed is 23 metres per second and the drift angle 10‹ the point R of intersection of the 23 metre and 10‹ lines is noted on the chart and the transparent circle is placed over the chart with its zero graduation in line with the point Q. The point on the circle which lies above the point R is then joined to the centre P of the circle and the line so obtained is the wind vector.
