Abstract
Abstract A printer having a plurality of decades each having a pivotal verge and print and readout wheels adapted to be simultaneously indexed by the verge. An eccentric rotatably mounted on the verge engages a power roll for oscillating the verge for indexing the wheels, and an electromagnet having an armature for latching the verge and eccentric is operable for releasing the latch for indexing the wheels.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
162 words
In a multiple wheel register having a plurality of coaxial register wheels and a wheel indexing mechanism for each of the register wheels comprising a pivotal stepping member pivotal for indexing the wheel in stepwise fashion, operating means operable for pivoting the stepping member for indexing the wheel and control means for selectively operating the operating means for selectively indexing the wheel, the improvement wherein the register comprises an elongated power roll rotatable about an axis generally parallel to the axis of the coaxial register wheels, wherein the wheel indexing mechanism comprises a cam rotatably mounted on the respective stepping member for engagement with the power roll for being rotated thereby for pivoting the stepping member, spring means biasing the stepping member in one pivotal direction for biasing the cam into engagement with the power roll, and wherein the control means comprises an electromagnetic operator having an armature operative to latch the respective stepping member in at least one pivotal position thereof.
Claim 2
Dependent Claim
162 words
In a multiple wheel register having a plurality of coaxial register wheels and a wheel indexing mechanism for each of the register wheels comprising a pivotal stepping member pivotal for indexing the wheel in stepwise fashion, operating means operable for pivoting the stepping member for indexing the wheel and control means for selectively operating the operating means for selectively indexing the wheel, the improvement wherein the register comprises an elongated power roll rotatable about an axis generally parallel to the axis of the coaxial register wheels, wherein the wheel indexing mechanism comprises a cam rotatably mounted on the respective stepping member for engagement with the power roll for being rotated thereby for pivoting the stepping member, spring means biasing the stepping member in one pivotal direction for biasing the cam into engagement with the power roll, and wherein the control means comprises an electromagnetic operator having an armature operative to latch the respective stepping member in at least one pivotal position thereof.
Claim 3
Dependent Claim
31 words
In a multiple wheel register according to claim 1 wherein the armature is operative for latching the cam against rotation by the power roll in cooperation with latching the stepping member.
Claim 4
Dependent Claim
37 words
In a multiple wheel register according to claim 1 wherein the armature is operative to latch the pivotal stepping member against the bias of the spring means as the stepping member is moving toward the power roll.
Claim 5
Dependent Claim
45 words
In a multiple wheel register according to claim 3 wherein the armature is operative to latch the pivotal stepping member against the bias of the spring means at each of two pivotal positions of the stepping member as it is moving toward the power roll.
Claim 6
Dependent Claim
128 words
In a multiple wheel register having a plurality of coaxial wheels, a wheel indexing mechanism for each of the wheels comprising a stepping member connected to be reciprocated back and forth for indexing the wheel in stepwise fashion, operating means operable for reciprocating the stepping member back and forth for indexing the wheel and control means for selectively operating the operating means for selectively indexing the wheel, the improvement wherein the register comprises an elongated power roll rotatable about an axis generally parallel to the axis of the coaxial wheels and wherein each wheel indexing mechanism comprises a cam rotatably mounted on the respective stepping member for engagement with the power roll for being rotated thereby for reciprocating the stepping member back and forth for indexing the wheel.
Claim 7
Dependent Claim
128 words
In a multiple wheel register having a plurality of coaxial wheels, a wheel indexing mechanism for each of the wheels comprising a stepping member connected to be reciprocated back and forth for indexing the wheel in stepwise fashion, operating means operable for reciprocating the stepping member back and forth for indexing the wheel and control means for selectively operating the operating means for selectively indexing the wheel, the improvement wherein the register comprises an elongated power roll rotatable about an axis generally parallel to the axis of the coaxial wheels and wherein each wheel indexing mechanism comprises a cam rotatably mounted on the respective stepping member for engagement with the power roll for being rotated thereby for reciprocating the stepping member back and forth for indexing the wheel.
Claim 8
Dependent Claim
22 words
In a multiple wheel register according to claim 5 wherein the cam is circular and is eccentrically mounted on the stepping member.
Claim 9
Dependent Claim
27 words
In a multiple wheel register according to claim 5 wherein the control means comprises releasable latching means for latching the cam against rotation by the power roll.
Claim 10
Dependent Claim
36 words
In a multiple wheel register according to claim 7 wherein the releasable latching means is operable for latching the cam against rotation by the power roll at each of two angularly spaced positions of the cam.
Claim 11
Dependent Claim
39 words
In a multiple wheel register according to claim 7 wherein the releasable latching means provides for latching the stepping member against movement in at least one direction in cooperation with latching the cam against rotation by the power roll.
Claim 12
Dependent Claim
33 words
In a multiple wheel register according to claim 5 wherein the operating means comprises spring means biasing the stepping member in one direction for biasing the cam into engagement with the power roll.
Claim 13
Dependent Claim
30 words
In a multiple wheel register according to claim 5 wherein the control means comprises releasable latching means operable for latching the stepping member against movement in at least one direction.
Claim 14
Dependent Claim
47 words
In a multiple wheel register according to claim 11 wherein the releasable latching means comprises a pivotal latch having a first pivotal position for latching the stepping member and an electromagnetic operator for pivoting the latch from its said first pivotal position for releasing the stepping member.
Claim 15
Dependent Claim
67 words
In a multiple wheel register according to claim 5 wherein each wheel has an annular arrangement of spaced detent pins and wherein the corresponding stepping member is pivotally mounted for pivotal reciprocable movement and comprises a pair of generally opposed pawls engageable with the wheel pins for indexing the wheel in stepwise fashion and insertable between the pins to provide for pivotal overtravel of the stepping member.
