Abstract
Abstract A multi-purpose tool which in a preferred embodiment is a flattened member having upper and lower flattened edges of predetermined width, with the lower edge having a groove extending along the edge receivable of a wing nut and of the shaft on which a wing nut would be mounted, and defining a through-space between opposite flattened faces of the tool with one face defining a circular shape around said through-space and having a diameter slightly less than that of a predetermined valve-face of a water-outlet valve of an aircraft gasoline tank such that upward pressure opens the valve whereby water in the bottom of the gas tank is drainable through the through-space of the tool, and an opposite face of the tool defining a circular perimeter around the through-space and having aligned with a diameter of the through-space oppositely extending slots along the surface of that face of the member, and extending about perpendicularly from the groove-containing edge a narrowed shaft portion continuous with a handle portion embodying interconnected convex screw driver head, Phillips screw driver head and a flatfaced screw driver head extending in different directions from one another in a common plane with the members opposite flat faces.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
72 words
A tool device comprising in combination a member having a substantially first flat face defIning a substantially circular through space passing therethrough, said through space having a predetermined diameter slightly less than that of the face of a water-drain valve of an aircraft gasoline tank, said member defining in at least one face thereof grooves extending in opposite directions from the edges of said through space and aligned with about said diameter.
Claim 2
Dependent Claim
72 words
A tool device comprising in combination a member having a substantially first flat face defIning a substantially circular through space passing therethrough, said through space having a predetermined diameter slightly less than that of the face of a water-drain valve of an aircraft gasoline tank, said member defining in at least one face thereof grooves extending in opposite directions from the edges of said through space and aligned with about said diameter.
Claim 3
Dependent Claim
50 words
The device of claim 1 in which said member includes a second flat face opposite from said first flat face, with said through space extending between and through each of said first and second flat faces, and with said grooves extending in opposite directions being in said second flat face.
Claim 4
Dependent Claim
108 words
The device of claim 2, in which said member includes a substantially flat faced edge structure having a predetermined thickness and said edge structure defining a slot extending in alignment with said edge structure, at least one portion of said slot being defined in sufficient depth and width to receive a male-threaded shaft on which a female-threaded wing-nut would be mountable, and said slot being of a predetermined width and depth sufficient to receive opposite wings of a wing-nut, the shaft-depth portion of said slot being central of oppositely-extending wing nut-receiving depth portions of said slot, said shaft-depth portion of said slot being continuous with said through space.
Claim 5
Dependent Claim
54 words
The device of claim 3, in which said member further defines a handle structure including a shaft portion extending from and about perpendicular to said slot-containing edge structure with an elongated hand-graspable shaft structure about vertical to said shaft portion and about parallel to said slot-containing edge structure and integral with said shaft portion.
Claim 6
Dependent Claim
36 words
The device of claim 4, including a Phillips screw driver head extending axially from one end of said shaft structure and a flat-bladed screw driver head extending axially from an opposite end of said shaft structure.
Claim 7
Dependent Claim
73 words
The device of claim 5, including extending intermediately between said Phillips screw driver head and said flat-bladed screw driver head and about perpendicular to said shaft structure and aligned about along the longitudinal axis of said axis portion a convex flat screw driver blade extending outwardly from said shaft structure, said member defining an opposite edge substantially opposite from said groove-containing edge, said convex screw driver blade extending outwardly from said opposite edge.
Claim 8
Dependent Claim
39 words
The device of claim 6 in which said Phillips screw driver head, said flat-bladed screw driver head and said convex screw driver head are intimately connected such that one offers non-rotating support for the other within said handle structure.
Claim 9
Dependent Claim
108 words
The device of claim 1, in which said member includes a substantially flat faced edge structure having a predetermined thickness and said edge structure defining a slot extending in alignment with said edge structure, at least one portion of said slot being defined in sufficient depth and width to receive a male-threaded shaft on which a female-threaded wing-nut would be mountable, and said slot being of a predetermined width and depth sufficient to receive opposite wings of a wing-nut, the shaft-depth portion of said slot being central of oppositely-extending wing nut-receiving depth portions of said slot, said shaft-depth portion of said slot being continuous with said through space.
Claim 10
Dependent Claim
23 words
The device of claim 1, in which in said first flat face circumscribing said through-space is a recessed shoulder receivable of said valve.
