Sash Holder.

Patent for a new and improved sash holder. This design "relates to that class of sash-holders in which the sash is held at any desired height, and locked when held down by means of a latch pivoted to angular upright wings which are integral with side plates securing the elastic cam, and adapted to impinge and bind upon the window-frame; and the novelty consists, in connection with the elastic cam, of the metallic plates arranged one upon each side of the said cam, and secured thereto by means of a pivotal device" (lines 17-27)
