| 'R.{Sir Henry Royce} C. HARRIS. A.M.I.E.E. CONSULTING ELECTRICAL AND MECHANICAL ENGINEER. PHONE 618 GATESHEAD YOUR REF. OUR REF. GEN/R.{Sir Henry Royce} Messrs. Rolls Royce Ltd. Nightingale Road, Derby. x728. Shaftesbury House. Prince Consort Road, Gateshead on Tyne. 30/7/30. Dear Sirs, I am enclosing herewith a brief description of a Direction Indicator which I have recently protected, & I should be glad to know if you are prepared to entertain the manufacture of same. The indicator is not a cheap "Gadget" & does not merely indicate that you are turning to the right or left, but can be arranged to give any required number of different signs, six signs are mentioned in the description, & any sign would be shown simultaneously at the front & rear of the car. It is very probable that, sooner or later, legislation will be introduced compelling the use of some such indicator, & I believe the arrangement described can be adapted to meet practically all requirements. Hoping this will receive your favourable consideration, I am Yours faithfully, R C Harris | ||
