发明名称 Cable support for workmen on roofs
摘要 Workmen are required to spray whitewash on sloping glass roofs such as used in greenhouses at certain seasons and then to scrub the whitewash off the glass later on. Ordinarily workmen support themselves on the narrow gutter alongside the roof or between roofs. According to the invention, brackets are installed at each end of the gutter and, if the roof is long, intermediate the ends. Two cables are supported by each set of brackets. The workman wears a safety belt from which extend two short ropes having snap books to be attached to the cables.
