Abstract
428,348. Variable-speed ratchet gearing. PEACOCK, E., Bintang Timor, Polewell Lane, Barton Seagrave, Kettering, Northamptonshire. Nov. 7, 1934, No. 31946. [Class 80 (ii)] Three slotted levers D, each pivoted at one end to a fixed casing 0 and arranged equidistantly apart, embrace a variable-throw eccentric B mounted on the driving shaft A, whereby they are caused to oscillate, the motion being transferred to arms E, mounted freely on the shaft A, by pins F projecting from the arms into slots in the free ends of the levers D. Pawls L pivotally mounted on the arms E coact with internal ratchet teeth of the driven member H, the pawls being moved through springs by levers G pivoted on the arms E and engaging the eccentric B. The throw of the eccentric is varied by an axially-movable control collar C, to which is linked a roller K engaging between the eccentric and an inclined part of the shaft A.
