Wire dispenser

Claim 2

A wire dispenser comprising: a lower circular dish having a floor, a cylindrical wall and a central aperture, said aperture having an inwardly extending coaming; an upper circular dish having a roof, a cylindrical wall and a central aperture, said aperture having an outwardly extending coaming, said cylindrical wall having an edge flange with an inner diameter larger than the outer diameter of the edge of said lower dish and in which the wall of the upper dish meets said edge flange to form a circular shoulder having inner and outer diameters equal to the respective inner and outer diameters of the wall of said lower dish at its edge; and means for fastening said upper dish, concave downward, onto said lower dish in a concave upward position.

Claim 3

A wire dispenser in accordance with claim 1 in which the edge of the wall of said lower dish is expanded into a cylindrical edge portion having a diameter greater than that of the wall.

Claim 4

A wire dispenser in accordance with claim 2 in which said cylindrical edge portion contains an external axial spline and in which said edge flange of the upper dish contains an internal slot matching said spline.

Claim 5

A wire dispenser in accordance with claim 1 in which said central apertures in lower and upper dishes are circular and have the same diameters.

Claim 6

A wire dispenser in accordance with claim 1 in which said means for fastening comprises a plurality of speed nuts and matching machine screws.

Claim 7

A wire dispenser in accordance with claim 1 in which the upper and lower dishes are made of a moldable plastic material having a high impact strength and having negligible memory.

Claim 8

A wire dispenser comprising a lower dish made of acrylonitrile-butadiene-styrene having a thickness in the range 0.078 inch to 0.125 inch, said dish having a flat floor and a cylindrical wall having a selected inner radius; a cylindrical edge portion of said wall having an inner radius exceeding said selected radius; a central circular opening in said floor having a diameter equal to approximately one-third of the diameter of said lower dish; an inwardly extending coaming on said central circular opening, said coaming being curved and faired into said floor; an axial spline in said edge portion; four speed nuts placed at equally spaced locations on the edge of said edge portion; an upper dish made of the same material as said lower dish and having the same thickness, said upper dish having a flat roof and a cylindrical wall having the same radius as that of said edge portion of the lower dish; a cylindrical edge flange of said upper dish wall having an inner diameter greater than the outer diameter of said edge portion; a central circular opening in said roof having the same diameter as the opening in said lower dish; an outwardly extending coaming on said central circular opening of the upper dish, said coaming being curved or faired into said roof; an axial slot in the inner surface of said edge flangE; and four holes placed equidistantly around said edge flange and bearing the same angular relation to said slot as the four speed nuts on the lower dish bear to the spline, whereby when the upper dish is placed on the lower dish, with slot-fitting spline, the four holes in the upper dish register with the four speed nuts on the lower dish.

Claim 9

A wire dispenser comprising a lower dish made of acrylonitrile-butadiene-styrene having a thickness in the range 0.078 inch to 0.125 inch, said dish having a flat floor and a cylindrical wall having a selected inner radius; a cylindrical edge portion of said wall having an inner radius exceeding said selected radius; a central circular opening in said floor having a diameter equal to approximately one-third of the diameter of said lower dish; an inwardly extending coaming on said central circular opening, said coaming being curved and faired into said floor; an axial spline in said edge portion; four speed nuts placed at equally spaced locations on the edge of said edge portion; an upper dish made of the same material as said lower dish and having the same thickness, said upper dish having a flat roof and a cylindrical wall having the same radius as that of said edge portion of the lower dish; a cylindrical edge flange of said upper dish wall having an inner diameter greater than the outer diameter of said edge portion; a central circular opening in said roof having the same diameter as the opening in said lower dish; an outwardly extending coaming on said central circular opening of the upper dish, said coaming being curved or faired into said roof; an axial slot in the inner surface of said edge flangE; and four holes placed equidistantly around said edge flange and bearing the same angular relation to said slot as the four speed nuts on the lower dish bear to the spline, whereby when the upper dish is placed on the lower dish, with slot-fitting spline, the four holes in the upper dish register with the four speed nuts on the lower dish.
