Abstract
A speed retarding governor particularly adaptable to a carriage of a typewriter wherein the speed of a traversing typewriter carriage is retarded by the cooperation of a plurality of arcuate pivotless lightweight flyweights that are floatably disposed within a cylindrical governor housing. A drive pin fixed to a rotating typewriter escapement toothed drive wheel engages an end of a first flyweight which abuts a second flyweight whereby both flyweights rotate therewith. The centrifugal force thus generated forces the two felt-lined flyweights outwardly against the internal peripheral surface of the governor housing which has now been rendered stationary, to produce a retarding force necessary to retard the speed of the traversing carriage.
