Checkwriter

Claim 2

In a checkwriter having an accumulator, the combination comprising means including a plurality of manually settable sectors, each of said sectors being differentially settable from a home position for setting up an amount to be printed, each of said sectors being effective when in said home position to set up a special symbol to be printed; cyclically operable drive means, means operable by said drive means for printing amounts and symbols set up by said sectors, means operable by said drive means for thereafter returning said sectors to said home positions, said last mentioned means being effective to momentarily arrest said sectors when said sectors register zero, means for operatively connecting said accumulator to said sectors during said return movement of said sectors whereby to drive said accumulator, and means for disconnecting said accumulator when said sectors are momentarily arrested.

Claim 3

The combination according to claim 1 wherein said means for returning said sectors comprises a series of intermeshing gear teeth, said series of teeth being interrupted whereby to momentarily arrest the return movement of said sectors when said sectors register zero.

Claim 4

The combination according to claim 1 comprising means for blocking said sectors on zero registering position, and means operable by said drive means for rendering said blocking means effective when said sectors move toward zero register positions and for rendering said blocking means ineffective upon said disconnection of said accumulator.

Claim 5

The combination according to claim 1 comprising means for blocking said sectors in zero registering positions, means operable by said drive means for connecting said accumulator and for rendering said blocking mean effective, said last mentioned means being effective to concurrently disconnect said accumulator and to render said blocking means ineffective after said sectors are blocked in zero registering positions.

Claim 6

The combination according to claim 1 comprising means for blocking said sectors in zero registering positions, and means controlled by said drive means after said sectors are blocked in zero registering position for rendering said blocking means ineffective and for disconnecting said accumulator.

Claim 7

The combination according to claim 1 wherein said means for operatively connecting said accumulator to said sectors comprises gear trains having oppositely rotatable sets of gears, means for normally entraining one of said sets gears with said accumulator, and selectively settable means for entraining the other of said sets of gears with said accumulator.

Claim 8

The combination according to claim 1 wherein said means for operatively connecting said accumulator to said sectors comprises gear members driven by said sectors, a first set of gears meshing with said gear members, a second set of gears meshing with said first set of gears, means for Normally entraining one of said sets of gears with said accumulator during said return movement of said sectors whereby to drive said accumulator in one direction, and selectively settable means for moving said first and second sets of gears together about the axes of said gear members whereby to enable said last mentioned means to entrain the other of said sets of gears with said accumulator during said return movement of said sectors whereby to drive said accumulator in the opposite direction.

Claim 9

In a checkwriter having an accumulator, the combination comprising means including a plurality of manually settable sectors, each of said sectors being differentially settable from a home position for setting up an amount from zero to nine to be printed, each of said sectors being effective when in said home position to set up a special symbol to be printed; cyclically operable drive means, means operable by said drive means for printing amounts and symbols set up by said sectors, means operable by said drive means for thereafter returning said sectors to said home positions, said last mentioned means being effective to momentarily arrest said sectors when said sectors register zero, means for operably connecting said accumulator to said sectors during said return movement of said sectors whereby to drive said accumulator, said last mentioned means comprising members driven by said sectors, a first set of gears meshing with said first set of gears; said sets of gears being moveable about the axes of said gear members from one position wherein said first set of gears is effective to drive said accumulator in one direction to a second position wherein said second set of gears is effective to drive said accumulator in the opposite direction, spring means for normally maintaining said sets of gears in said first position, means including a depressible key for moving said sets of gears into said second position; a latch for maintaining said sets of gears in said second position, and means controlled by said drive means for invariably releasing said latch after said sectors are returned to said zero positions.

Claim 10

In a checkwriter having an accumulator, the combination comprising means including a plurality of manually settable sectors, each of said sectors being differentially settable from a home position for setting up an amount from zero to nine to be printed, each of said sectors being effective when in said home position to set up a special symbol to be printed; cyclically operable drive means, means operable by said drive means for printing amounts and symbols set up by said sectors, means operable by said drive means for thereafter returning said sectors to said home positions, said last mentioned means being effective to momentarily arrest said sectors when said sectors register zero, means for operably connecting said accumulator to said sectors during said return movement of said sectors whereby to drive said accumulator, said last mentioned means comprising members driven by said sectors, a first set of gears meshing with said first set of gears; said sets of gears being moveable about the axes of said gear members from one position wherein said first set of gears is effective to drive said accumulator in one direction to a second position wherein said second set of gears is effective to drive said accumulator in the opposite direction, spring means for normally maintaining said sets of gears in said first position, means including a depressible key for moving said sets of gears into said second position; a latch for maintaining said sets of gears in said second position, and means controlled by said drive means for invariably releasing said latch after said sectors are returned to said zero positions.
