Abstract

515,773. Adjusting motor car lamps. NEER, H. G. J. VAN. June 30, 1938, No. 19456. [Class 97 (i)] Apparatus for adjusting motor car lamps and measuring their intensity comprises two photometers 14 and 15 in front of screens 21 and 22 with horizontal lines 23 and 24. The photometers are horizontally adjustable and have pointers' 16 and 17 moving over a scale 18. The whole framework carrying photometers and screens is adjustable on vertical rails 1 and 2 to which it may be clamped by screws 6 and 7. Its position is indicated by pointers 8 and 9 moving over scales 10 and 11.
