WINDOW-CLEANING DEVICE.

Application filed December 10, 1926. Serial'NO. 153,941;

This invention relates to improvements so as to dispense with the usual labor of applying water to the glass pane to be cleaned and then drying the pane.

A further object of the invention is the provision of a window cleaning device which automatically applies water to the pane to be cleaned upon sliding movement of a window sash in one direction and for thoroughly drying the paneaupo'n movement of the sash in the-opposite direction. I

A still further object of the invention is to provide awindow cleaning device off-the class mentioned which is easy to apply to a window or removed therefrom; slmpl'e of construction, and thorough of operation.

With these and other objects in view, the invention resides incertainnovel construction' and combination and arrangement of part'sifthe essential features of which are hereinafterfully described, are particularly pointed out in the appended cla in1s,' and are illustrated in the accompanying drawing, in which Figure" l isa perspective View of my improved window cleaning device per se.

Figure 2 is a horizontal sectional View through a window showing the device 'in position thereon.

Figure 3 is a vertical sectional view therethrough showing a moistening element in engagement with the window.-

Figure 4 is a sii'nilar view but showing the position of the parts witlrtlie squeegee in engagement with the glass pane. I Figure 5 is a vertical 's'ectioi'ia'l view on the line 5-5 of Figure 2. n

Figure 6 is a detail perspective view of the moistening element removed from its holder. I Fi ure 7 is a detail'horizon-tal. sectional view showing the manner of holding t-h'e device to a window casing for cleaning an upper sash.

Figure 8 is a detail front elevational View oi one of the end brackets Referring more particularly to the draw- I ings, the reference numeral lOdesignates my improved window cleaning device in its entirety and which includesan elongated bar 11 which supportsb'rackets 12', 12 at. opposite ends and which bracketsezctend from the bar for turnably means 13 and drying means 14;.

The moistening element-l3. comprises a holder 15 which is oi a length to fit between the

brackets

12, 12 and which is constructed of metal and provided with a socket 16 to irictionally receive a removable moistening element 17 in the natureof a piece of cloth composed of aplurality of layers of mate= rial, or the same may be a strip of felt so as to hold water when dipped therein, and

' which element is saturated before placing the same in the holder for use. The holder 15 has pintles 18 which have "then-bearings in the brackets 12 and which have gear segments 19 fixedly mounted thereon. Wheels 20 are freely mounted on the pintles 18'and have a rubber tire or tread surface 21 which supporting moistening projects beyond the front of the brackets for contact with the vertical rails of a window sash in a manner to be presently explained. The wheels20 are under "tension to cause them to normally rotateiwith the -gear' se m'ent 19, byreason ofrfiat springs .22 W ll-10% bear-against the inner side faces of the wheels 20. However, when the force to r0- tate the wheels overcomes the tension ofl the springs; the wheels will rotate irrespective of the goals for apurpose to-be presently explained. I w

The drying means-.14 comprises a holder 23 which supports astrip' of relatively stiff.

flexible material 24 such 'as a strip of rubber and which constitutes a squeegee. The

holder 23 has its ends provided with ears 25 which" are connected with stub shafts 26 having bearings'in the bracketsl 2 to one side of the erticalaXi's' of the pint'les 18. The

stub shafts have :gear segments 27 fixed thereon for constant meshing engagement with the gear segments 19 whereby move ment is transmitted from the gear segments 19' to the gear segments 27' to move the squeegee into engagement with the window glass to be wiped after the application of water thereto by the moistening element.

In Figures 2, 3 and 4, I have shown my invention applied to a window N which includes a window casing C having vertical parting strips P and P within which the upper and lower sashes U and L are slidably mounted. For the purpose of rigidly supporting the cleaning device with respect to the sash for cleaning the outside of the glass pane G, I provide attaching means 28 at opposite ends of the device and which means comprises spaced rails or tracks 29 provided on the brackets 12 and which slidably receive clamps 30 which have clove-tail grooves 30 for receiving the dove-tail tracks 29. The clamps include U-shaped jaws 31 for receiving the parting strip P for rigidly clamplng the device thereon. A. set screw 33 is threaded in the brackets and .serves as a stop for the clamp to prevent sliding movement of the same with respect to the brackets when in an adjusted position upon the window casing.

In operation, the device is clamped on the parting strip P when it is desired to clean the outside of the window pane G of the lower sash L and it is attached by inserting the U-shaped clamps over the parting strip at a point adjacent the meeting rails of the upper and lower sashes and thence tightening up upon .the clamping screws 32. It will be understood that it is first necessary to wet the moistening element and insert the same in its holder and to raise the lower sash to mount the device upon the window casing. When in position as shown in Figure 3 of the drawings, the rubber tires of the wheels 2-0 are tight against the vertical rails R of the lower sash with the moistening element 17 bearing against the outside surface of the pane and completely, spanning the same from one siderail to the other. The lower sash being in a raised position, is now manually lowered to slide downward and as it moves down the tendency of the same is to rotate the wheels 20, which being under tension serve to forcibly press the moistening elements against the window pane to wet the pane and wipe off any dirt or dust which might be present thereon. Should the friction between the wheels 20 and the window sash overcome the tension of the flat springs 22, the wheels will slip or turn but will still maintain a pressure upon the moistening element. As the sash reaches the limit of its downward movement and the entire length of the window glass has been washed, the operator manually raises the sash, and in so doing, causes a reverse rotation of the wheels 20 which operates the

gear segments

19 and 27 to cause the moistening element to swing outward away from the glass and automatically swings the sash back and forth without manual labor 7 on the partof an operator other than that necessary to raise and lower the sash. When cleaning the upper sash U, the clamps 31 are removed and the set screws 33 tightened against the window casing as shown in Figure 7 of the drawings.

For locking the parts against movement when not in use, I provide a sliding bolt 34% on one end of the squeegee holder 23 which is movable into a recess 35 provided in the inner wall of the adjacent bracket.

From the foregoing description it will be seen that I have provided a window cleaning device whichmay be applied to a window of a given size to thoroughly clean the same by merely sliding the sashes up and down, but which device may be constructed of various sizes to fit the standard size sashes.

While I have described what I-deem' to be the most desirable embodiment of my invention, it is obvious that many of the details may be varied without in any way de-' parting from the spirit of my. invention, and

I therefore do'not limit myself to the exact details of construction herein setforth nor to anything less than the whole of; my invention limited only by the appended claims. 7
