1350902 Liquid fuel dispensing apparatus DRESSER EUROPE SA 19 April 1971 [29 Jan 1970] 4434/70 Heading A4T In a mixed liquid fuel dispenser blend knob 4, Fig. 1 rotates spur gear 8, Fig. 2 to select the ratio of two basic fuels and alter the increment gearing driving price register 9. Clockwise (on) rotation of lever 3 moves pawl 10 between spurs on gear 8 to lock the blend setting and through an over-center and lost motion linkage 11, 14, 22, and sector 20, Figs. 2, 4a and 4b, a register reset motor 15 is switched on which, after completing the reset, operates latched pump start switch 16. Anti-clockwise (off) movement of lever 3 switches off the pumps before pawl 10 is withdrawn from gear 8. Clockwise movement of lever 3 moves link 13 and cranked link 13c pivoted at 13a on link 13, at 13b on pawl 10 and at 12b on crank 12a to rotate shaft 12 from the position in Fig.4a to that in Fig.4b, so that link 22 moves whereby blend gear 8 is locked by movement of pawl 10 before the last part of the pin and slot lost motion at 22a is taken up under action of spring 11 and sector 20 turned to effect resetting and finally to switch on the pumps. On turning lever 3 "off", lost motion at 22a allows rotation of shaft 12 whereby linkage 17 thereon directly unlatches and switches off the pumps before the pawl is withdrawn and before sector 20 returns to "off". The blend knob rotates against a spring- loaded indexing roller and cam, while spaces between the gear spurs for which there are no blends are blocked by screws. (For Figures see next page) |
