Abstract
Abstract A small pocket size, manually actuatable adding machine. The machine is circular, of a size to be held in the hand. It is operated by a dial or rotor having ten equally spaced finger holes. It comprises counter wheels overlying each other and stators between the counter wheels. The manual rotor or dial carries a radially movable catch member which can be positioned to engage the periphery of individual counter wheels whereby the rotor can cause any individual wheel to be rotated any predetermined part of a revolution corresponding to a digit to be entered. A unique transfer means comprising stator members between adjacent wheels and a pawl carried by each rotor is provided whereby upon a full revolution of an individual wheel, a step movement is imparted to an adjacent wheel.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
97 words
A calculating device comprising: an assembly of a plurality of counterwheels rotatable about a common axis, said wheels being of progressively varying diameter, said wheels being in a position overlying each other; transfer means between the wheels whereby a predetermined revolution of a wheel imparts a step movement to an adjacent wheel; means for manually feeding numerical inputs selectively to individual wheels comprising a member selectively engageable with the periphery of any one of the wheels; and means for rotating said member about the axis of said wheels to impart predetermined angular rotation to the selected wheel.
Claim 2
Dependent Claim
97 words
A calculating device comprising: an assembly of a plurality of counterwheels rotatable about a common axis, said wheels being of progressively varying diameter, said wheels being in a position overlying each other; transfer means between the wheels whereby a predetermined revolution of a wheel imparts a step movement to an adjacent wheel; means for manually feeding numerical inputs selectively to individual wheels comprising a member selectively engageable with the periphery of any one of the wheels; and means for rotating said member about the axis of said wheels to impart predetermined angular rotation to the selected wheel.
Claim 3
Dependent Claim
27 words
A device as in claim 1, wherein said member is mounted to be movable radially with respect to the wheels for selective engagement of the individual wheel.
Claim 4
Dependent Claim
20 words
A device as in claim 2, wherein said member includes a projection engageable with the peripheral part of individual wheels.
Claim 5
Dependent Claim
24 words
A device as in claim 1, including a dial constructed to be manually rotated through selected increments, said member being carried by said dial.
Claim 6
Dependent Claim
34 words
A device as in claim 4, wherein said dial comprises a circular member having equally spaced configurations formed in it adapted to be manually engaged for moving the dial through increments of a revolution.
Claim 7
Dependent Claim
19 words
A device as in claim 5, wherein said dial is mounted to rotate about the axis of said wheels.
Claim 8
Dependent Claim
27 words
A device as in claim 1, including a housing having said wheels therewithin, said last means comprising a dial being mounted in the top of said housing.
Claim 9
Dependent Claim
63 words
A device as in claim 1, including stator members positioned between adjacent wheels, each transfer means comprising an element carried by a wheel in a position to be engageable with a part of an adjacent stator, each wheel having extending projections and said element being movable whereby to engage a projection on an adjacent wheel to move the adjacent wheel through one step.
Claim 10
Dependent Claim
41 words
A device as in claim 8, wherein said stator member has an extending projection over which said movable element rides whereby to be moved radially into a position to engage a projection on an adjacent wheel to advance it one step.
Claim 11
Dependent Claim
41 words
A device as in claim 1, wherein said wheels are configurated to have peripheral parts lying in a common plane, said member being positioned to be movable radially adjacent to peripheral parts of the wheels which lie in a common plane.
Claim 12
Dependent Claim
21 words
A device as in claim 3, wherein the individual wheels are cup shaped, said peripheral parts lying in a common plane.
Claim 13
Dependent Claim
125 words
A calculating device comprising: an assembly of a plurality of counterwheels rotatable about a common axis; transfer means between the wheels whereby a predetermined complete revolution of a wheel imparts a step movement to an adjacent wheel; and stator means adjacent to the wheels, each transfer means comprising a movable element carried by a wheel in a position to be engageable with a part of the stator means, each wheel having extending projections and each said element being movable whereby to engage a projection on an adjacent wheel to move the adjacent wheel through one step, said stator means having projections positioned to be engaged by a movable element to move the element radially into a position to engage a projection on an adjacent wheel.
Claim 14
Dependent Claim
125 words
A calculating device comprising: an assembly of a plurality of counterwheels rotatable about a common axis; transfer means between the wheels whereby a predetermined complete revolution of a wheel imparts a step movement to an adjacent wheel; and stator means adjacent to the wheels, each transfer means comprising a movable element carried by a wheel in a position to be engageable with a part of the stator means, each wheel having extending projections and each said element being movable whereby to engage a projection on an adjacent wheel to move the adjacent wheel through one step, said stator means having projections positioned to be engaged by a movable element to move the element radially into a position to engage a projection on an adjacent wheel.
Claim 15
Dependent Claim
22 words
A device as in claim 12, wherein said element embodies a flexible arm whereby the end of the arm can flex radially.
Claim 16
Dependent Claim
17 words
A device as in claim 12, wherein said stator means comprises stator members positioned between adjacent wheels.
