Mr. Harris is a carpenter, painter aud jack of all trades who has invented and uses the portable window jack shown iu the photograph. He is not a window washer, but posed as one on his patent platform to please the photographer. The jack is made of twenty-one pieces fitted together on two triangular bases, with a binding rod which tits against, the inner sides of the window frame and is tightened with a screw similar to a jackscrew. The platform folds into a portable box, which looks like a suitcase. The whole thing weighs twenty-five pounds and can easily be carried by the worknau. Harris can take the frame from its case and put it up in a window in two minutes. x He changes from one window to another of the same width in a few seconds. The binding rod is adjustable and fits any window win-dow as wide as eight feet- A straight rod across the bottom of the two triangles not shown here enables him to st the frame up in the middle of a high window.
