Book 3 — Hinge Lock for Horizontal Sliding Windows
Reading edition
A simple catch for fixing windows of the horizontal sliding type so that it is difficult to pry them open is shown in the sketch. It is made of an old hinge, one end of which is sharpened so as to engage the surface of the frame on which the sash slides. When not in use the hinge is folded up. It can be used to set the window at various points when it is desired to have it partly open.—T. H. Linthicum, Annapolis, Md.
