Abstract
Abstract A device for measuring and exhibiting the length and width of the human foot which comprises a first movable member adapted to be placed in contact with the end of a foot and a second movable member adapted to be placed in contact with the side of the foot. The device also includes an alpha-numeric display means which is adapted to exhibit at a single location the various lengths and widths of a foot and means responsive to the placement of the movable members for enabling the exhibition in the display means of the specific length and width of the foot measured.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
164 words
An electronic device for measuring and exhibiting the length and width of a human foot, said device comprising, a base, a first slidable member movable on said base and adapted to be placed in contact with the end of a foot supported by said base, a second slidable member movable on said base and adapted to be placed in contact with the side of said foot, said slidable members being independently slidable relative to each other, a first reference member located at one end of said base for positioning of the heel and a second reference member located on said base perpendicular to the first reference member for positioning of one side of the foot, said reference members establishing the reference planes for the measurement of the foot, electronic means responsive to the placement of said slidable members, and changeable character alpha-numeric display means responsive to said electronic means adapted to exhibit at a single location the various lengths and widths of a foot.
Claim 2
Dependent Claim
164 words
An electronic device for measuring and exhibiting the length and width of a human foot, said device comprising, a base, a first slidable member movable on said base and adapted to be placed in contact with the end of a foot supported by said base, a second slidable member movable on said base and adapted to be placed in contact with the side of said foot, said slidable members being independently slidable relative to each other, a first reference member located at one end of said base for positioning of the heel and a second reference member located on said base perpendicular to the first reference member for positioning of one side of the foot, said reference members establishing the reference planes for the measurement of the foot, electronic means responsive to the placement of said slidable members, and changeable character alpha-numeric display means responsive to said electronic means adapted to exhibit at a single location the various lengths and widths of a foot.
Claim 3
Dependent Claim
86 words
The invention in claim 1 wherein said means responsive to the placement of said slidable members comprises a plurality of electrically conductive contacts placed in a combinational pattern on said base, adjacent the path of said first and second slidable members, a nonconductive material covering said electrically conductive contacts, said first and second slidable members including pin contactors adapted to sense various combinations of said contacts in accordance with the position of said slidable members, said contacts being spaced in accordance with standard shoe size dimensions.
Claim 4
Dependent Claim
56 words
The invention of claim 2 wherein a portion of said electrically conductive contacts placed in a combinational pattern include a plurality of parallel electrically conductive strips which extend at an angle from the path of the first slidable member, the pin contactor of said second slidable member being adapted for selectively contacting one of said strips.
