" 'STATES MARY JOSEPHINE PRINGLE, OF ST. PAUL, BLKIJXYITESOTA.

WINDOW VIASHER AND CLEANER.

Application led October 16, 1923. Serial No. 668,878.`

To all whom it 'may concern:

Be it known that l, MARY JosnPHINr. PRINGLE, a citizen of the United States, and a resident of St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in l/Vindow Washers and Cleaners, of which the following is a specification.

This invention relates to a window washer and cleaner, and has for its object to provide a device of this character which is capable of performing the various operations requisite to thorough washing and cleaning of windows or the like and which is extremely simple and of light weight construction and yet durable and sufficiently rigid to enable it to effectively carry out its functions, the device being also adapted to be manufactured at a comparatively slight expense from materials and by means of facilities ordinarily available.

Other objects and advantages of the invention reside in certain novel features of the construction, combination and arrangement of parts which will be hereinafter' more fully described and particularly pointed out in the appended claim, reference being had to the accompanying drawings forming part of this specification7 and in which:

Figure 1 is a fragmentary perspective view, showing the preferred embodiment of the invention and illustrating the brush alone mounted in the frame;

Figure 2 is a view similar to Figure 1 but showing the cloth also mounted in the frame; and

Figure 3 is a View in transverse vertical section on line 3-3 of Figure Q..

Referring to the drawings wherein for the sake of illustration is shown the preferred embodiment of the invention, the numeral 10 designates a brush which includes a rectangular block 11 of wood or the like constituting a brush head from which the bristles or tufts 12 extend, the bristles beling suitably mounted .in the brush head. Each corner of the brush head is provided with a V-shaped recess 13 for a purpose which will hereinafter more fully appear.

A combined handle and frame, designated at 15, is provided and as shown in the drawings is preferably constructed of two pieces of resilient wire, designated at 16 and 17. The piece 16 is bent to provide one side 18 and the ends 19 of the gripping frame, the

other' side of the frame being constituted by a portion 20 of the other piece '17. The portion 20 of the piece 17 extends between the ends 19 of the gripping frame and .beyond the points where this portion intersects the ends 19 the wire 17 is intertwisted with the portions of the wire 16 which 'extend from the ends 19. lt is to be understood that the portion of the wire 17 which makes up one side of the gripping frame occurs `intermediate and centrally of the ends of the wire and similarly the portions of the wire 16 which make up the side 18 and ends 19 of the gripping frame occur intermediate and centrally of the ends of the wire 16 and that the end portions of the wires 16 and 18 which lie on each side of said intermediate portions are intertwisted throughout their lengths to provide twisted wire elements 22. These twisted wire elements 22 are then extended from the gripping frame to provide a pair vof converging arms 23. At the point where these converging arms meet the twisted wire elements 22 are themselves intertwisted to provide a shank 2d. A gripping handle or element 25 is secured to the outer end of the shank 24.

In use the brush 10 is carried by the gripping frame, the corners of the gripping frame being engaged in the recesses 13 in the corners of the brush head and the bars of the frame being engaged with the side faces of the brush head. 1t is to be understood that the wires which make up the gripping frame possess sufficient resiliency to enable the frame to be snapped into the recesses 13. At the same time this wire when twisted to form the arms 23 and shank 211 provides an elongated and rigid handle for the brush. ln order that the wiping of the window as well as other cleaning operations may be provided for, a cleaning cloth 30 is provided and is draped over the brush head 11 and extends down over the tufts or brush bristles 12, as shown in Figures 2 and 3. Of course it is to be understood that the cloth 30 is associated with the brush before the gripping frame is associated therewith. After the cloth has been associated with the brush the frame is then snapped into the recesses 13 and the cloth and brush are firmly and securely held to the combined frame and handle 13. The portions of the cloth 30 which lie against the back of the brush afford a broad flat surface of cloth which may be conveniently utilizedA to wipe the window. The portions of the cloth which hang down alongside ot the brush and bristles may also be utilized in Various cleaning operations.

It is to be understood that the distance between the end barsv 16 of the gripping ranie is approximately vequal t0 the length of the brush head so that these bars will snugly' Ht against the ends` of the brush headI in assembly'. The distance between the side bars 17`and 18 of the gripping ranie isalsof/approximately equal to the width of theA brush yhead and the side bar 2O connects ywith the end bars 19, at points just short of the distance between these end bars.,

19',"th,e end bars beingA deflected inwardly, asl 'at 19?` forthis purpose. In assembling the gripping frame with the brush head the cornersfof the frame between its end bars 19 and its side bar 1S are brought into their recesses 13, and the traine is then rotated downwardly to snap the inwardly deiiected terminals 19a ofthe side bars 19 into engagement with the opposite recesses 13.

I claiin:

ln a window cleaner, the combination with a cleaning element having a rectangular head provided at its corners with V- shaped recesses7 and a combined handleand trarne constructed of two piecesA of resilient wire, one piece being bent to provide side and end bars of thel gripping ltraine, the other piece being bent to provide the other side bar oi the gripping frame, said gripping frame cooperating with the \/shaped recesses of the head, the wires being intertwisted beyond the gripping frame and bent to provide a shank.`
