| Show 1 na g POPULAR SCIENCE window clean ng apparatus the invention sho in the aarom ai corn lanying drawing has been derigi cd pil by S C lawlor of D fluth minn for use in cleaning the outer surfaces of win dows doms by a person operating from the inside thus avo I 1 d ng the exposure in operated from the interior cold weather and the danger of filling rom the window lahe appa atus consists of a horien tal tube with spring actuated rods rod pro ejecting fiam either end to press against the sides of the window frame and having a sliding block mounted on the tube to support a level levei con trolling the act on of a vertical mem her ber which extends outside the build ing and carr es the cleaning devices inside the N vertical member is a rubber cord secured at the lower end and connected with the sl ding cleaner at the top by pulling on a cord which runs over the pulley at the elbow and lies parallel with the controlling lever the cleaner is lowered from the top ty the bottom ot the sash while the r motion Is effected by the coid to put the apparatus appal atus in operation the rods are contracted sufficiently to per mit engagement with the window frame the window sash having been previously raised to allow the pa sage of the vertical tube the lever is then grasped in one hand and the cord in the other thus exert ng a pressure on the glass as the cleaner is raised and lowered metr c system in great britain the united states consul general at london forwards a letter from the secretary of the decimal association of england on the subject of the agi
