Abstract
Abstract A two-bladed windshield wiper adapter which tilts the wiper blades in the sweep movement direction. The adapter is formed with a plug receiving portion loosely fitted to a cross plate having two plug members disposed perpendicular thereto for receiving the wiper blades. The adapter has the ability to pivot and tilt at the position where the plug receiving portion is coupled to the cross plate.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
131 words
An adapter for supporting two wiper blades on a reciprocating windshield wiper drive arm comprising a cross plate having first and second posts extending essentially perpendicular therefrom for independently pivotally supporting said two wiper blades, respectively, said cross plate having an opening therein intermediate said first and second posts, and a plug member fitted in said opening for rotational and tilting movement for coupling said adapter to said drive arm, said plug member including a gap defined by opposing walls of said plug member, said opening in said cross piece being situated in said gap of said plug member, the configuration of said gap restricting the tilt of said cross plate to insure that the surfaces of said two wiper blades remain on said windshield during reciprocation of said drive arm.
Claim 2
Dependent Claim
131 words
An adapter for supporting two wiper blades on a reciprocating windshield wiper drive arm comprising a cross plate having first and second posts extending essentially perpendicular therefrom for independently pivotally supporting said two wiper blades, respectively, said cross plate having an opening therein intermediate said first and second posts, and a plug member fitted in said opening for rotational and tilting movement for coupling said adapter to said drive arm, said plug member including a gap defined by opposing walls of said plug member, said opening in said cross piece being situated in said gap of said plug member, the configuration of said gap restricting the tilt of said cross plate to insure that the surfaces of said two wiper blades remain on said windshield during reciprocation of said drive arm.
Claim 3
Dependent Claim
20 words
The adapter as claimed in claim 1, wherein said gap is slightly wider than the thickness of said cross plate.
Claim 4
Dependent Claim
24 words
The adapter as claimed in claim 2, wherein the opposing walls defining said gap are truncated conical surfaces opening away from said cross plate.
Claim 5
Dependent Claim
21 words
The adapter as claimed in claim 3, wherein said first and second posts extend in opposite directions from said cross plate.
