Abstract
An extensible scraping and brushing tool for use in removing ice and snow from vehicle windows or the like has an elongate handle provided with a scraper member at one end and has a brush assembly that is telescopically received in the handle. The brush assembly is nested in the handle when the tool is to be used as a scraper or as a brush of a relatively short length or, the brush assembly may be extended from such a first position to a second position in which the brush assembly extends beyond the handle in order that the tool may be used as a brush having an extended reach. Guide structure for reciprocably shifting the brush assembly and retaining the same in connection with the handle is formed integrally as a part of the handle and brush assembly and is of a configuration providing a relatively high degree of rigidity at the point of connection between the two when the tool is in its extended condition. The brush assembly and the handle are so constructed that the complete tool may be assembled by press-fitting the components together, eliminating the need for fasteners or other special assembly procedures.
