Abstract

Abstract A tennis scoring portable computer manually operated by the person holding the computer, the computer including three sets of paired wheels, the handle portion of each wheel being exposed for manual manipulation such that the wheel is rotatable manually, and an indicia carrying portion of each wheel being exposable through a window for each wheel disclosing tennis-scoring indicia, the particular indicia being viewable through the window being dependent upon the position to which the wheel is turned by manual adjustment of the handle portion, one set of wheels being paired separate wheels for indicating the respective scores of opposing players for the points of a single game, the several points listed on each wheel of the points set being love, 15, 30, 40, deuce, add, and game, a second set of paired wheels one for each of opposing players includes separate positions on each wheel for scores ranging from the number one through the number seven, and the third set of wheels each having numbers corresponding to sets for each of three different positions numbered one, two, and three, the face of the computer between opposing ones of each pair identifying each of the three sets of pairs as points, games, and sets, and a first column of one of each set being identified as one tennis player and a second column of the remaining one of each pair of the three sets being identified as the other tennis player.

Claim 1
Independent Claim 143 words
A portable tennis scoring device comprising in combination: an enclosure having at least one substantially planar face having defined therein three pairs of windows with each pair spaced from the other two pairs and with each window of each pair spaced from the other of that particular pair, six separately rotatable wheels mounted for independent rotation such that a handle portion of each wheel extends through a port and is accessible for turning the wheel, and such that another portion of the wheel carrying tennis-scoring indicia turns beneath a window for each respective wheel, said six wheels being divided into three pairs corresponding to the three pairs of windows, each wheel of a first pair carrying identical point-scoring indicia, each wheel of a second pair of wheels carrying identical game-scoring indicia, and each wheel of a third pair of wheels carrying setsscoring indicia.
Claim 2
Dependent Claim 143 words
A portable tennis scoring device comprising in combination: an enclosure having at least one substantially planar face having defined therein three pairs of windows with each pair spaced from the other two pairs and with each window of each pair spaced from the other of that particular pair, six separately rotatable wheels mounted for independent rotation such that a handle portion of each wheel extends through a port and is accessible for turning the wheel, and such that another portion of the wheel carrying tennis-scoring indicia turns beneath a window for each respective wheel, said six wheels being divided into three pairs corresponding to the three pairs of windows, each wheel of a first pair carrying identical point-scoring indicia, each wheel of a second pair of wheels carrying identical game-scoring indicia, and each wheel of a third pair of wheels carrying setsscoring indicia.
Claim 3
Dependent Claim 37 words
