Abstract

627,949. Ratchet gearing. HUMPHREYS & GLASGOW, Ltd., and HOBBS, A. F. Sept. 8, 1947, Nos. 24648/47, 9091/48 and 18400/48. [Class 80 (iii)] Mechanism for driving a curved rack 10 from a reciprocating pawl 14 comprises two rockers 18, 20 mounted on fixed pivots 34, 36 and connected by a link 22 at 30, 32, the member 18 carrying the pawl 14, and the end 28 of a reciprocating ram 12 connected through a link 26 to the mid-point 24 of link 22, so that the pivot points 28, 32, 24, 30 are substantially in a straight line throughout the stroke of the ram 12. A second pawl may be provided on rocker 20 to drive the rack intermittently in the opposite direction, one of the pawls being held out of engagement. The pawls may be double headed to act alternately and drive the rack continuously, and two rams, e.g. 50, 50a, Fig. 5, may be provided to act alternately, a third rocker 52 being provided. The pawls may be formed as toothed sectors so as to roll on the rack teeth and prevent wear through sliding. The invention is particularly applicable to operating revoluble grates of gas furnaces. Fig. 8 shows an arrangement wherein the grate operating rack is driven independently from a pinion 72 actuated by pawls 14, 38 on rockers 18, 20 pivoted on shaft 70 of the pinion 72, connected through linkwork 22, 76, 78 with the ram 12.
