Be it known thatI, ROBERT V. VVARGA, a citizen of the United States, residing at St. Louis city, in the State ofMissouri, have invented new and useful. Improvements in ivindow Locks, of which the following is a specification. I Y

This invention relates to window locks and its principal object is to provide a window lock which will lock and positively hold the window in any raised position.

An object of the invention is to provide a lock of this character which'embodies a;

toothed or serrated bar to be carried by one segment for engagement with the tooth of the serrated bar to hold the two sashes in locked position with respect to each other.

With the preceding and other objects and advantages in view, the invention consists in the'novel combination of elements and arrangement of parts and operations to be hereinafter specifically referred to, illustrated in the accompanying drawings, and pointed out in the appended claim. 1

In the drawings;

Figure 1 is a fragmentary elevation of a window having my invention associated therewith. r v

Figure 2 is an enlarged fragmentary 'sectional view of the window having the invention applied thereto, the invention being shown in elevation, and

Figure 3 is a top plan view of thetoothed segment and its mounting.

Referring to the drawings in detail wherein corresponding characters of reference denote corresponding parts throughout the several views, the numeral 5 designates an Lshaped plate having openings 6 therein to receive screws or other fastenings 7 to hold the L-shaped plate to the upper face of the lower sash as shownv in Figure 2.
