and State of California,.have invented-he tam new and useful lmprovemenltsuuf Gravity-Actuated WindcwsLocks of which; the following is aspecification. j My invention relates tofa; gravity actu.-;'

ated window lock and the; objects farefto provide a simple, economically"constructedv and easily installed lock forwindow sashes, and more particularly onejthat will, auto-1' matically lock the two sashesi-together'when' the window is closed or nearlyclosed.

My invention is applicable to and may be fitted to any windowsashes, and'it can be placed on thesashes so that thewindo'w may locked and at the same'time be be securely open at the top orbottom to allow for ven tilation.

Vith these and other objects in viewg'as" will appear hereinafter, my invention consists of certain novel features ofconstruc-g tion, combination and arrangement of parts as will be described in detail and particuv larly set forth in the appended claim,,refer ence being had to the accompanying drawings, and to the characters of reference thereon, which form a partof this specification, in which:

Figure 1 is an elevational view of twowindow sashes in their. relative positions showing the locks in position thereon and the window closed, Fig. 2 is a side eleva- 'tional view thereof, Fig. 31s a front. elevapart attached to the upper tional view of the sash, Fig. 4 is a side elevational view thereof, showing the different positions of the latch by dotted lines, Fig. 5 is 'a top view thereof, Fig. 6 is a sectional view of the plate portion looking in one direction, Fig. 7 is a sectional view of the same looking in the opposite direction, Fig. 8 is a side eleivational view of the latch, Fig.'9 is anelevational view of the same at right angles to Fig. 8, Fig, 10 is a top view thereof, and Fig. 11 shows the bearing plate which is to be attached to the lower sash.

Similar characters of reference refer to similar parts throughout the several views.

My lock consists of plate 1, latch 2, catch 3, and bearing plate 4. Plate 1 is rectangular shaped and of a suitable size to be fitted into the side of a' window sash and is provided with holes l into which screws are ash. is
