WINDOW-CLEANIN G DEVICE;

Application filed April 9,

This invention relates to an llIlPI'OWiECl win- .zIlOW cleaning device especially adapted for attachment to thewindow frame to cooperatewith the outside surfaces of thewindow panes, the device being such, in construction, as to automatically wipe such surfaces when the sashes are moved up and down. i

My principal aim is to provide a simple and inexpensive device which can be conveniently attached to the window frame and which will operate in the automatic manner specified to obviate the necessity of exposing. ones self to danger by sitting in the window and leaning out in the customary manner.

The structure of .the device is such as to permit it to function as safety automatic window cleaning device, the same being adjust-ably made to fit upon the window frame, and including a flexible wiping strip in contact with the outside surfaces of the window pane.

In the drawings Figure l is an outside elevational view of the ordinary window, showing the device attached to the frame in operative position.

Fig. 2 is a vertical section taken approximately on the line 22 of Fig. 1.

Fig. 3 is an enlarged sectional and elevational View showing a close-up of the structure to represent more clearly the cooperation of the wiperwith the window pane.

Fig. 4 is a top plan view of Fig. 3.

Fig. 5 is a horizontal section through the window structure showing certain of the parts in dotted lines.

Fig. 6 is a perspective view of one of the attaching brackets, and

Fig. 7 is a perspective view of the extensible or adjustable supporting member, and

Fig. 8 is a. perspective view of the extensible or adj ust-able supporting member.

The supporting member last referred to, is generally designated by the numeral 9. This member as shown better in Figs. 7 and 8 comprises a substantially rectangular tube 10 and a slide 11, which is slidably mounted therein, the slide having an elongated slot to accommodate certain bolts to be hereinafter more fully described.

These parts 10 and 11 are arranged in telescoping relation to cooperate with the attaching bracket-s. Each bracket is designated by the numeral 12 in general and as shown in Fig. 6 comprises a suitably shaped socket 13 and attaching flanges 14. This bracket is 1928. Serial No. 268,530.

adapted to befirmly bolted upon the window Irame, as shown in Fig. 5. Thus, the two brackets when properly positioned serve to.

ings 20 at longitudinally spaced points for adjustable connection with the bolts. The bolt, of course, passes through openings in the tubelO and then through the slot in the part 11. The plate 16 is formed with upstanding ears 21, with which corresponding ears on a retaining member are pivoted. This retaining member includes a dove-tailed jaw portion 22, cooperating withthe plate 16, to holda rubber wiper 23 in contact with the window glass 24. The retainer includes a finger piece 25, and a cooperating spring 26. Hence, the plate together with the retainer, forms a clamp for the rubber strip 23, which clamp is bodily adjustable on the supporting member 9.

This cleaner will serve to clean either the top or bottom window, and this may be accomplished by appropriate adjustment of the a bottom plate adjustable wiper clamp. For cleaning the upper window, the clamp is adjusted outwardly, and for cleaning'the lower one, it is merely pushed in, to bring the wiper into contact with the glass of the lower window. In practice, the attaching brackets are permanently fastened to the window frame, at about the point indicated, or just where the upper and lower sashes meet, thereby permitting the device to be properly arranged for the dual cleaning operation specified.

Only one of the adjustable supporting devices and a'single wiper clamp is absolutely essential, since the clamp can be adjusted to either half of the window longitudinally ofthe supporting member, and the supporting member can be bodily removed and transferred from window to window to clean the glass in the manner specified.

I desire to emphasize the adjustable clamp and to mention this. Wet felt is first inserted after it is adjusted for the top or bottom window. Then a strip of rubber to dry the window is employed. This is the reason that there are holes in the top so that it can be adjusted or placed in proper position for either the top or bottom Window.

It is thought that by considering the description in connection With the drawings, a clearunderstanding of the invention and advantages will be quite clear to persons familiar With devices of this class. Therefore, a more lengthy description is regarded unnecessary. v I 7 Minor changes coming Witlnn thefield of invention claim-ed may be resorted to, if desired.

' outer ends removably arranged in the socket portion of said attaching brackets, retaining bolts associated With the telescopically connected sections for maintaining said sections in adjusted position, and Wiping means .embodying a Wiping element and retaining clamps for said elements, said clamps being disposed at right angles to said supporting member, and including portions extending across and intersecting the supporting memher, and connected therewith by said retaining bolt.

2. A Window cleaning device of the class described comprising a pair of attaching brackets, each including a socketed portion and attaching flanges, a longitudinally extensible supporting member occupying a position between the brackets and adapted for horizontal disposition and including telescopically connected'sections Whose end por tions are receivable in the socketed portions of said brackets, retaining bolts for said sectrons, a wiping element disposed in spaced parallelism with respect to supporting members, and adapted to contact the Window glass, and clamps for said element serving to adj ustably mount the element on the supporting member, said clamps being disposed at right angles to said supporting member and each comprising a spring pressed retainer pivotally mounted on an apertured bottom plate, said bottom plate being adjustably connected with the supp rting member through the medium of the aforesaid retaining bolt.

in testimony whereof I aflix my signature.
