Abstract: 334,608. Siemens - Schuckertwerke Akt.-Ges., and Kalkner, F. June 8, 1929. Searchlights, directing.-A deflecting apparatus of a searchlight in which the movements of a deflecting arm and the movements of a projector are synchronized e.g. by electrical means, is so arranged that the tilting angle e and swivelling angle # of the deflecting arm are connected by the relation tan e = sin #. tan a where a is the angle of inclination of the lighting plane. The deflecting arm 5 is rotatable about two axes at right angles, the axis JK through the uprights 3 and 4 and the axis CD of the turntable 2. Uprights 7 and 8 on a turntable 6 form mountings for a guide body 12 in the form of a semi-circular hoop rotatable about axes CD and MN. By means of pointers 9 and 10 moving over scales 9a and 10<a> the rotation and inclination of the guide member may be set to the required angles and locked in position by screws 16 and 17. The deflecting arm is then free to move in the plane of the member 12, its position being determined by a pointer 5f moving over a knife edge F. The arm 5 may be arranged to control the movement of the projector 20 or, conversely, may merely indicate the direction of the projector. In the former case the movement of the arm about the axis JK is transmitted to the projector by racks 38 and 40, spur wheel 41 and an electric system 42, 43 whilst the movement about the axis CD is transmitted by pinions 23, 24 and an electric system 25, 30 to similar mechanism associated with the projector as shown in the Figure.
