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.
Claims34
A carriage retarding governor for typewriters that includes a traversable carriage, the movement of which is regulated by an escapement mechanism that includes a rotatable toothed escapement drive wheel that is coupled to a carriage rack by an integral shaft and pinion gear, the carriage retarding governor comprising:
- a rotatable housing having an arcuate wall;
- a pivotless segment disposed within said housing;
- means on said housing for selectively rendering said housing stationary;
- and
- means for engaging and urging said segment to rotate under the influence of the movement of the carriage and be centrifugally displaced and wedged against said stationary housing thereby retarding the traverse of the carriage.
A carriage retarding governor for typewriters that includes a traversable carriage, the movement of which is regulated by an escapement mechanism that includes a rotatable toothed drive wheel that is coupled to a carriage rack by an integral shaft and pinion gear, the carriage retarding governor comprising;
- a rotatable housing having an arcuate wall;
- a pair of pivotless segments disposed within said housing;
- means on said housing for selectively rendering said housing stationary;
- and
- means on the toothed drive wheel for engaging and urging said segments to rotate under the influence of the movement of the carriage and be centrifugally displaced and wedged against said stationary housing thereby retarding the traverse of the carriage.
A carriage retarding governor for typewriters that includes a traversable carriage, the movement of which is incrementally regulated by an escapement mechanism that includes a rotatable toothed drive wheel that is coupled to a carriage rack by an integral shaft and pinion gear, the carriage retarding governor comprising in combination:
- a rotatable cylindrical housing;
- a pivotless arcuate segment freely disposed within said housing;
- a plurality of teeth on said housing selectively engageable by the escapement mechanism for rendering said housing stationary;
- and;
- a rigid stud on the rotatable drive wheel for engaging and urging said segment to rotate under the influence of the movement of the carriage and be centrifugally displaced and wedged against said stationary housing thereby retarding the traverse of the carriage.

- a rotatable cylindrical housing;
- a pair of arcuate segments freely disposed within said housing;
- a plurality of teeth of said housing selectively engageable by the escapement mechanism for rendering said housing stationary;
- and;
- a rigid stud on the rotatable drive wheel for engaging and urging said segments to rotate under the influence of the movement of the carriage and be centrifugally displaced and wedged against said stationary housing thereby retarding the traverse of the carriage.
A carriage retarding governor for typewriters that includes a traversable carriage, the movement of which is regulated by an escapement mechanism that includes a rotatable toothed drive wheel that is coupled to a carriage rack by an integral shaft and pinion gear, the carriage retarding governor comprising:
- a rotatable housing having an arcuate wall;
- a pair of arcuate segments freely disposed within said housing;
- means on said housing for selectively rendering said housing stationary;
- a rigid pin on the toothed drive wheel for engaging ends of said segments for urging said segments to rotate under the influence of the movement of the carriage and be wedged against said stationary housing to initially retard the traverse of the carriage and thereafter be centrifugally displaced against said stationary housing to further retard the carriage traverse;
- and
- varying means on said arcuate segments to provide a wedging force of said segments against said stationary housing.
A carriage retarding governor for typewriters that includes a traversable carriage, the movement of which is regulated by an escapement mechanism that includes a rotatable toothed drive wheel that is coupled to a carriage rack by an integral shaft and pinion gear, the carriage retarding governor comprising:
- a rotatable housing having an arcuate wall;
- a pivotless segment disposed within said housing;
- means on said housing for selectively rendering said housing stationary;
- means for engaging and urging said segment to rotate under the influence of the movement of the cartridge and be centrifugally displaced and wedged against said stationary housing thereby retarding the traverse of the carriage;
- and
- means on said segment for limiting the peripheral contact of the ends of said segment against said housing wall to provide an initial braking.
