| Abstract: |
A squeegee for mounting on the back of a operator's hand, comprising a base portion; a device for attaching the base portion to a operator's hand, such device preferably a strap, a upwardly projecting portion attached to said base at its lower end, the upwardly projecting portion being flexible and thin enough for good wiping qualities. The outwardly projecting portion being thick enough to avoid a tendency to ride over the top of water on a smooth surface to be squeegeed.

I claim:
1. A squeegee for mounting on the back of an operator's hand comprising a base elongated from left to right and having left and right ends and front and rear sides, said base having an undersurface having a forward side and a rearward side, the lowermost portions of the outer edges of which lie substantially in a first plane, an upwardly projecting protrusion attached to said base and also elongated from left to right, a hand-encircling means for extending around an operator's hand, attaching means attaching said hand-encircling means to said base, said protrusion having a forward side and a rearward side together defining a pair of elongated sides extending along the elongation of said protrusion, said protrusion having an upper end having a wiping edge on at least one side of its said pair of sides, said wiping edge having at least one elongated portion extending from left to right, said pair of sides extending along the elongation of said protrusion and transversely to said first plane, there being for reference a second plane parallel to said first plane and extending through said wiping edge, said forward and rearward sides of said protrusion being spaced to provide a specific flexibility such that when pressure is placed on said protrusion so that it bends to that one of its pair of sides which is opposite from said one side on which said wiping edge is disposed then the attack angle which said one side of said protrusion makes with respect to a second plane parallel to said first plane will be substantially 20 degrees to 40 degrees when said bending is caused by a pressing force from an operator's wrist which is at substantially the maximum which will not dislodge from an operator's face a pair of over-the-ear bow type of spectacles on which is the lens being wiped, such spectacles having a capability of gripping the operator's head with an average gripping resistance to the dislodging of the spectacles by such a wiping force when such force is applied during a horizontal motion of the squeegee.
