ulated from within a room to clean the exter-' nal surface of the window pane, and is so constructed as to permit the ready 1nter-' changeability of the various tools required in window cleaning, such as a scraper for re-- moving paint spots and grit, a brush, a drying pad and a squeegee.

The above and other objects will become apparent in the description below, in which characters of reference refer to like-named 7 K the clamp. The tongue 28 of a detachable parts in the drawing. Referring briefly to the drawing, Figure 1 is a top plan view of the window cleaner.

Figure 5 is a side elevational view of the upper end of the window cleaner showing the clamp member and means whereby the head is secured to the device.

Referring in detail to the drawing, the numeral 10 indicates a rod, hollow throughout its length. This rod has a collar 11 mounted at its upper end in which a threaded wing nut 12 is mounted. The lower end of the hollow rod 10 has an extension 13 continuing from it at an angle. This extension, together with the rod 10 of which it forms a part, and further extension 14 continuing at an angle with the extension 13, form a substantially U-shaped member which is adapted to pass from the outside of a window to the inside, beneath the window. The extension or bar l l has a collar 15 mounted at its end which is similar to the collar 11 and is also provided with a wing nut 16. This bar 14 is of hollow construction and receives the length, is formed. intermediate portlon of a spreader .lever 23* stem 17 of a removable handle 18. The rod 10 telescopingly receives a spindle 19, in such manner that the-spindle may be adjusted or projected to various lengths to suit the particular requirements of the window which is to be cleaned. The upper end of the spindle 19 has anchored thereto a saddle bracket 20. This saddle bracket seats upon it a cylindrical clamp member 21. At one position longitudinally on the clamp a slit 22 i formed and diametrically opposite the slit a relatively-short slot 23 is provided. Beneath the slot 23 a second slot 24, of similar The slot 23 receives the which is permanently fixed in such a way that it may notbe removed from'the slot 23. This spreaderlever extends through the slit 22 in head is adapted to beslipped into the s1ot-24 this detachable head comprises a cleaner plate 26 which, on its reverse side, is provided with These hinge ears are spaced- I apart from each other andproject rearwardly, receiving between them a fixing tongue 28? The fixing tongue, when the spreader lever has beenlifted to increase the dimensions of the slit 22, is inserted into the slot 24 and remains in propped position in the clamp. The clamp, being resilient, urges the spreader lever into contact with the tongue 28 and thereby frictionally secures the cleaner in position on the remainder of the device.

The plate 26 of the cleaner headis adapted to be encased and covered by. a cloth oi chamois member 29 which is secured in place by a rubber band or the like and will present an appearance similar to that shown in Figure 3. This covering member 29 may be moistened or may be applied dry. -By slipping the portions 10 and 19 outside of a window and holding the portionlt and the handle 18 within a room the entire outer surface of a window pane may be cleaned by lifting and lowering the cleaning head in a reciprocal movement. To compensate for different sizes of windows-the outer members 18 and 19 are made mutually telescoping and extensible.

With a device of this type it is unnecessary for persons cleaning windows to sit upon the sill outside of the Window and thereby make themselves liable to injury.

It is to be noted that certain changes in form and construction, such as the substitution of a squeegee, scraper, brush or similar other related devices in place of the cleaning head illustrated, may beincorporated without departing from the spirit and scope 0f the invention.

I claim: 7 1. In a Window cleaner having an arm adapted to support a cleaning head, a substantially cylindrical clamping member attached to said arm, a cleaning head having a tongue projecting therefrom, said member. being resilient and having an opening extending longitudinally throughout its length, openings in said member at points distant from said first-named opening, said tongue being releasably insertable first through said first-named opening and then through one of said second-named openings, and means extending through said first-named opening. and the other ofsaid second-named openings cooperating With said member to releasably retain said tongue in said member. 7 Q

2. In a window cleaner having an arm adapted to support a cleaning head, a'substantially cylindrical resilient clamping member attached to said arm, said member being slitted throughout its length, and having slots parallel With the slit at a distance 7 from the slit, a tongue adapted to be attached to a cleaning head, a lever extending through one of said slots and said slit, said tongue being insertable through said slit adjacent said lever and through the other of said slots,

V said'lever cooperating with said member to 0 releasably retain said tongue in said member. In'testimony whereof I affix my signature.
