? INVENTOR Hernzan Shep/ era Lellrcs ATTORNEY United States Patent ()fiice 2,852,796 Patented Sept. 23, 1958 2,852,796 WINDOW CLEANING TOOL Herman Stephen Leins, New York, N. Y.

Application April 20, 1954, Serial No. 424,368 1 Claim. c1. 15-220 The present device relates generally to window clean-,

ing tools and specifically to a device which permits the cleaning of the outer side of windows without climbing out of the window or other exposing of the person to the danger of falls or exposure.

The principal object of the invention is to provide a tool which handily extends out of the window which is open only a few inches and which permits the washing and wiping dry of the glass surface of many different sized windows.

Another object of the invention is the provision of quick-release locking means for the blade and holder so that squeegees of different materials may be quickly replaced and so that different length squeegees may be substituted in order that different sized windows may be easily cleaned.

A still further object of the invention is to provide a light weight holder and blade assembly which is readily and easily thrust out of the partially opened window and which is'not tiring to the person using it, and which has a conveniently disposed angled handle.

Yet another object of the present invention is to provide a replaceable blade having its supporting means on the holder positioned closer to one end of the blade than to the other so that the blade may be swung within limits according to the degree of tightness on the holder to positions angularly farther from the holder at one end than at the other for cleaning odd shaped corners and surfaces remote from the handle of the holder and by tipping the holder sideways against the direction of cleaning movement or wiping movement.

These and other objects and advantages of the present invention will be apparent from the following description when considered in connection with the annexed drawings in which like numerals indicate like parts throughout the several views and in which:

Fig. l is a plan view in elevation of the present invention as in position for cleaning a double-hung window,

Fig. 2 is a side view in elevation of the blade assembly and a portion of the holder,

Fig. 3 is an edge view of the blade in one embodiment,

Fig. 4 is an end view in section of .the blade assembly of Figs. 2 and 3 taken on line 44 of Fig. 2,

Fig. 5 is an end view in section of the blade assembly of Figs. 2 and 3 taken on line 5--5 of Fig. 3, and

Fig. 6 is an end view in section of another embodiment of the blade of the present invention.

Referring in more detail to the drawing, a window casement is indicated at 10 having a window 11 nearly closed leaving a space 12 out of which the tool may be projected at one end 13. The tool is substantially U- shaped with

parallel arms

14, 15, the arm 14 being longer than arm 15 and terminating in the outwardly angled substantially rectangularly shaped handle 16. The other arm 15 is bent inwardly at 17 to form a flattened portion A blade assembly shown generally at 20 in Fig. l is seen in Figs. 2 to 6 to consist of a relatively soft strip 21 of rubber or other resilient material faced on each side with a reinforcing strip or member 22, secured together by rivets 23 and washers 24. A thumb screw or wing nut 25 which fits on stud 19 secures the blade assembly 20 to the arm 15 of the tool and preferably the aperture 26 in the blade assembly 20 is closer to the lower end of the blade than to the upper, permitting reaching far corners on the other and outer surfaces of the window by leaving the thumb screw or wing nut 25 slightly loose and tipping the tool in the direction of the movement of cleaning or wiping. This permits the upper end of the blade assembly to swing away from the holder and in places of complex shapes of the moulding or conditions of obstructions to the sweep of the holder allows cleaning of otherwise hard to reach surfaces.

It is an important feature of the invention that the blade assembly be interchangeable with another, and the strip and reinforcing member's shown in Figs. 1 to 6 have their upper ends disposed substantially opposite the handle on the other arm. This permits, with the angled handle, reaching to the top end of the window, while it is.

scribed in detail, it is obvious that this invention is not to be considered as being limited to the exact form disclosed, and that changes in detail and construction may be made therein within the scope of what is claimed, without departing from the spirit of this invention.

Having thus set forth and disclosed the nature of this invention, what is claimed is:

A window cleaning tool comprising an elongated supporting holder of substantially U-shape having upwardly extending arms disposed in spaced parallelism to each other, one of said arms, adapted for positioning on the inner side of said window, being substantially longer than the other and connecting at its upper end with a substantially rectangular loop shaped handle, said handle being angled outwardly relative to said arms upwardly at substantially an angle of to afford a relatively firm grip, the bight of said tool being of a length substantially in excess of the thickness of a double window sash and disposed at substantially right angles to both said arms and adapted to engage the bottom of the window sash when the latter is in nearly closed position whereby the bottom of said window serves as a fulcrum for bringing the other leg of said tool against the outer surface of said window when relatively light downward pressure is exerted against said handle, the outer leg of said tool including a right angled inwardly turned projection substantially parallel to said bight with a flattened end in the plane of the holder having an aperture therein through which extends a threaded stud, a blade assembly including a resilient strip, a reinforcing strip for each of the wide sides of said resilient strip, said reinforcing and resilient strips having a plurality of aligned apertures extending therethrough, rivets extending through certain of said apertures and fixed on opposite sides of said reinforcing strip, another of said apertures being free and adapted for the reception of said threaded stud, a Wing nut adapted for relatively loose engagement with the projecting end of said stud on the side of the blade assembly opposite said flattened end thereby permitting said blade to pivot on said stud, said last mentioned aperture being relatively closer to the lower end of said blade than the upper whereby the upper end of the blade may be swung toward and away from said window when the tool is tipped in the direction of wiping to conform to irregularly configurated window shapes, said readily removable wing nut and threaded stud facilitating the ready interchange. of blades of different lengths, said longer handle extending above the upper end of the blade.
