M.{Mr Moon / Mr Moore} [Circular stamp with clock face] DEC 31 1914 RECEIVED [Typed text]: RE PETROL SYRINGE FOR EASY STARTING. 30.12.14. E3/G3C1214. With reference to your note on the above subject in which it is stated that, - "A modification would be to have a small hand pump to compress a small quantity of air in the upper part of a chamber partly filled with petrol. When a given pressure is obtained a very small cock could be opened and the whole rushes through a small hole in the induction pipe." I attach herewith a sketch illustrating this, in which the air and petrol are used from the tank on the car. In measuring, cocks each [handwritten above 'each': of which] receive a certain measured quantity of each fluid under pressure. A double movement of the lever on the dashboard from whatever position it may be in should discharge into the induction pipe a certain amount of mixture. The petrol cock itself should be possibly made larger than one would quantitatively expect, since before the entry of petrol it would contain air at atmospheric pressure. Several movements could be given to the dashboard lever to obtain sufficient starting gas | ||
