o 7 Application filed December 14,519 M This invention relates to improvements in cleaning devices, particularly to awindow cleaning demos, and it 1513116 prlnclpal ob- I v ject of my invention to provide asimple and 5 inexpensive device for cleaning windows, yet

eificient in operation and avoiding'the. dan-f ger resulting from the necessity of exposing the body; of the cleaner to falls from .a win- I dow, as the cleaningis done entirely from M Within a room.

o I Another object of my invention'is the pro-. vision of a window cleaning device comprising a handle simplyformed by bending a metal strapupon' itself, the'free ends of which] 7 I carry at their, oppositely disposed faces the cleaning implements. 4
