Abstract
Abstract A window cleaning apparatus is set forth wherein an elongate housing includes a downwardly extending forward housing receiving a sponge-like applicator mounted therein. Adjacent an apex of a second cylindrical housing directed downwardly from the first cylindrical housing is an upwardly extending boss including a resilient wiping strip secured therein. A ratcheting handle organization effects forward positioning of a piston to direct a cleaning fluid through the applicator sponge onto a window surface to be cleaned.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
177 words
A window cleaning apparatus comprising, an elongate body including a first hollow cylindrical housing secured in alignment to a second hollow cylindrical housing, wherein the first cylindrical housing defines a first chamber in communication with a second chamber defined within the second cylindrical housing, and a porous applicator head mounted at a forward end of the second cylindrical housing remote from the first cylindrical housing, and pressurizing means contained within the first cylindrical housing to direct a quantity of cleansing fluid contained within the elongate body between the pressurizing means and the applicator head for directing the fluid through the applicator head onto a surface to be cleaned, and wherein the first cylindrical housing is defined by a first axis and the second cylindrical housing is defined by a second axis, wherein the second axis is arranged at an obtuse angle relative to the first axis, and wherein the porous applicator head includes a truncated conical sponge member integrally secured within an internally threaded cap, the internally threaded cap being selectively securable to the second cylindrical housing.
Claim 2
Dependent Claim
177 words
A window cleaning apparatus comprising, an elongate body including a first hollow cylindrical housing secured in alignment to a second hollow cylindrical housing, wherein the first cylindrical housing defines a first chamber in communication with a second chamber defined within the second cylindrical housing, and a porous applicator head mounted at a forward end of the second cylindrical housing remote from the first cylindrical housing, and pressurizing means contained within the first cylindrical housing to direct a quantity of cleansing fluid contained within the elongate body between the pressurizing means and the applicator head for directing the fluid through the applicator head onto a surface to be cleaned, and wherein the first cylindrical housing is defined by a first axis and the second cylindrical housing is defined by a second axis, wherein the second axis is arranged at an obtuse angle relative to the first axis, and wherein the porous applicator head includes a truncated conical sponge member integrally secured within an internally threaded cap, the internally threaded cap being selectively securable to the second cylindrical housing.
Claim 3
Dependent Claim
52 words
A window cleaning apparatus as set forth in claim 1 including an elongate boss tangentially secured to an exterior surface of the first cylindrical housing adjacent a junction of the first cylindrical housing and the second cylindrical housing and the boss including an elongate, elastomeric wiper stip spaced above the sponge member.
Claim 4
Dependent Claim
71 words
A window cleaning apparatus as set forth in claim 2 wherein the pressurizing means includes a piston orthogonally mounted to a coaxially positioned piston rod, the piston and piston rod reciprocatably mounted within the first cylindrical housing, and the piston rod including a rear end directed exteriorly through a rear end surface of the first cylindrical housing and terminating in a handle, the handle arranged orthogonally relative to the piston rod.
Claim 5
Dependent Claim
111 words
A window cleaning apparatus as set forth in claim 3 including a first cylindrical housing handle directed and arranged orthogonally relative to the first cylindrical housing on an exterior surface thereof diametrically opposed to the boss member, the housing handle including a cavity, and an actuator lever pivotally mounted within the cavity with a lever spring mounted interiorly of the cavity and a rear surface of the handle to maintain the handle in an extended position relative to the cavity, and a remote end of the lever spaced beyond a pivot, the remote end including an engagement flange, the engagement flange biased at a raised orientation relative to the remote end.
Claim 6
Dependent Claim
69 words
A window cleaning apparatus as set forth in claim 4 wherein the piston rod includes a series of notches directed interiorly of an exterior surface of the piston rod and arranged in orientation opposed to that of the piston rod handle, wherein the notches are arranged for engagement with the engagement flange in a first position and are diametrically opposed to the engagement flange in a rotated second position.
Claim 7
Dependent Claim
75 words
A window cleaning apparatus as set forth in claim 5 further including a release rod arranged in alignment with the engagement flange spaced underlying the piston rod and directed through the rear wall of the first cylindrical housing, the release rod including a forward tip in selective engagement with the engagement flange with a release rod spring captured between the forward tip and an interior surface of the rear wall of the first cylindrical housing.
Claim 8
Dependent Claim
27 words
A window cleaning apparatus as set forth in claim 6 wherein the piston is in complementary sealing engagement with the first chamber of the first cylindrical housing.
