Abstract
A printwheel setting mechanism suitable for automatic daters or other printwheel units comprises a verge drive for each printwheel and a solenoid travelling on a carriage which is selectively positionable actuating any one of the verge drives. The verge drive includes a verge which oscillates to advance a starwheel as the solenoid is actuated and deactuated. A pin wheel fixed for rotation with the starwheel engages slots on the printwheel for advancing it.
Claims12
A printwheel setting apparatus for setting a plurality of printwheels, the apparatus comprising:
- a plurality of printwheel actuators respectively associated with a plurality of printwheels to be set, said printwheel actuators each comprising a verge and a starwheel, said starwheel being advanceable upon being contacted by said verge;
- means connected to said starwheel for advancing an associated printwheel when said starwheel is advanced by said verge;
- a single solenoid positionable for selectively operating each of said verges;
- and
- means for selectively positioning said solenoid operatively adjacent to respective verge for operating the verge of said selected printwheel actuators.
A printwheel setting apparatus for setting a plurality of printwheels, the apparatus comprising:
- a plurality of printwheel actuators, each of said printwheel actuators comprising a pin wheel having pins thereon for engaging a plurality of slots associated with corresponding printwheel, a starwheel fixed for rotation with the pin wheel, and a verge, said verge having arms operative upon oscillation of the verge to engage and advance the starwheel;
- spring means disposed adjacent, to and operatively position with respect to each said verge for providing a return force;
- a single solenoid positionable for contacting and moving each said verge against said spring means, when said solenoid is actuated, said spring means returning said verge when said solenoid is deactuated whereby said verge is oscillated for advancing the starwheel;
- means for selectively positioning said solenoid in juxtaposition to each verge of said printwheel actuators;
- and
- means for applying pulses to said solenoid.
A printwheel setting apparatus for setting a plurality of printwheels and a slogan block of a postage meter, the apparatus comprising:
- a plurality of actuators, each of said actuators comprising a pin wheel having pins thereon for engaging a plurality of slots associated with respective corresponding printwheels and a slogan block, a starwheel fixed for rotation with the pin wheel, and a verge, said verge having arms operative upon oscillation of the verge to engage and advance the starwheel;
- spring means disposed adjacent, to and operatively positiond with respect to each said verge for providing a return force;
- a single solenoid positionable for contacting and moving said verge against said spring means, when said solenoid is actuated, said spring means returning said verge when said solenoid is deactuated whereby said verge is osciallated for advancing the starwheel;
- means for selectively positioning said solenoid in juxtaposition to each verge of said printwheel actuators;
- and
- means for applying pulses to said solenoid.
