This supporter for sashes acts by friction, ilthough not in the ordinary way, which is to et the friction of the sash against the jamb hold up the window. This invention is particularly adapted to the windows of railroads, Dmnibuses, and to other small sashes. In the arrangement shown in our engravings, Fig. 1 is front .view, with part of the jamb removed, to show the supporter, and Fig. 2 a section through the invention. The same letters refer to similar parts in each. A is the window frame or jamb posts, and a sash, having a vertical movement. In a recess, /', in the frame, is placed the cord, E, and to the side of is attached the metal plate, C, whose outer edge is seen at a; another plate, D, is attached to it by an india rubber band, i, which passes through openings, c, in the plate. The outer edge of D is rounded, and the other has a shank, f, attached, which passes through a groove, e, in the stile of the sash. The operation is very simple : In raising the window, the thumb or finger is pressed upon the shank, which loosens C and D, from the cord, E; when raised high enough, the shank is released, and the india rubber band draws the plates, C and D, close against thus holding the window firm in its place. This sash supporter is the invention of Mr. Nathaniel E. Baker, of Holyoke, Mass., and from him all further particulars may be obtained. Patented October 13, 1857.
