Abstract
633,303. Preventing unauthorised use. CROWTHER, G. Feb. 20, 1948, No. 4993. [Class 7 (ii)] An anti-theft device for motor vehicles comprises a body 1 inserted in the engine fuel supply pipe 3 and carrying at least two rotatable valves 6 which permit a through passage for the fuel only when numbered plates 7 carried on their spindles are aligned with fixed marks 8 in a predetermined number sequence. In a modification the numbers are formed on the face plate 1 and the spindles 6 carry the marks 8. The valves are plug valves with a bore in each plug.
