Abstract: 127,907. Barr & Stroud, Barr, A., and Stroud, W. June 22, 1917. Range and height finders.-Apparatus for determining the heights (or horizontal distances) of targets comprises two scale-converting mechanisms, one for automatically converting motions according to the rangefinder scale into motions - corresponding to the logarithm of the range, and the other for converting motions in altitude into motions according to the logarithmic sine (or cosine) of the angle of sight, the two motions thus obtained being combined so as to show the height upon a logarithmic scale of heights (or the horizontal distance upon a logarithmic scale), or to impart motion in accordance therewith. In the construction shown in Fig. 1, the range-finder 1, slipported horizontally in forks. carries a spur-wheel 7 engaging a fixed circular rack 3 concentric with the axis about which the range-finder is turned in altitude by means of a working head 4. The motion of the spur-wheel 7, which corresponds to the motion in altitude of the range-finder, is transmitted through the gearing shown to a rack carrying a pointer 7 moving over a scale 20 on a rack 19, which is made to move, by means of the gearing shown, in accordance with the movements of the range-finding working head 13. In the construction shown in Fig. 3, the range-finder is movable in a vertical plane about an horizontal axis. The central parts which rotate with the range-finder are shown cross-hatched in the same sense as the part 23, and the stationary parts are shown cross-hatched in the same sense as the part 24.

The brake is urged towards the drum and the contacts 5, 6 (5 being fixed), are opened by means of a spring 36 surrounding the shaft 29 and anchored at its ends to the housing 24 and the lever 34, 35. When the brake is operative the nose 28 is engaged in the notch 26 and the blades are in a parked position. By pulling the cable 30 and securing it in its pulled position by means not shown the nose is removed from the notch, the brake is released and the contacts 5, 6 are closed so that the motor is energized and then operates the wipers. To stop the wipers the cable is released and the spring 36 then tends to urge the brake towards the drum and to open the contacts. However the motor continues to operate with the nose 28 riding over the periphery of the cam 25 until the nose enters the notch. The contacts 5, 6 then open and the brake is positively applied by the spring to instantly arrest the motion of the armature. In another embodiment the two armed lever 34, 35 is operated by an electric solenoid. To stop the wipers the solenoid is deenergized and the mechanism then operates as previously described. A band type brake may be used instead of the block type shown.
