摘要： 207,243. Thompson, W. P., (Townsend, J. R.). Aug. 21, 1922. Windows and the like, cleaning.-A brush 19 is supported in a holder 20 which is rotatably mounted at the end of a spring arm 1 bent at 2 to pass rotatably through the frame 7 of a motorvehicle windscreen and provided with a handle 12. In the horizontal position shown in Fig. 1, the wiper rests upon the weather-strip 23 along the upper edge of the lower panel 24. The brush is provided at one end with a stop 22 to prevent this end from passing below the arm 1, and when the handle 12 is raised the brush will traverse the screen and be brought horizontal by the upper edge of the frame 7. On the downward motion the tendency of the outer edge to lag will be corrected by the stop 22 so that the brush remains substantially horizontal and the moisture is lined vertically enabling subsequent accumulations of moisture to flow evenly downwards without obstructing the vision. If the lower panel has no weather-strip the brush may rest upon a clip fixed to the top edge of the glass.
