WINDOW-sass: LOCK.

Application filed January 14, 1924. Serial No. 686,035.

To (ZZZ whom it may concern:

Be it known that I, ANDREW J. GAYDOS,

a citizen of the United States residing at Cleveland, in. the county of Cuyahoga and State of Ohio, have invented certain new,

and useful Improvements in VVindow-Sash Locks, of which the following is a specification. I

This invention relates to improvements in window sash locks, having for an object to provide means which may be employed to retain a pair of window sashes'in any relatively adjusted position. i

Another object is to provide a lock of this character constructed so that in one position, operation thereof is facilitated. to permit quickadjustment of the sashes and when shifted. to another position the sashes will be positively locked against opening or relative shifting.

Other objects will be in part obvious and in part pointed out hereinafter.

In order that the invention and its mode of operation maybe readily understood by persons skilled in the art, I have in the accompanying illustrative drawings and in the following detailed description based thereon set out one possible embodiment of the same.

In these drawings:

Fig. 1 is a central vertical section of a window with my improved lock mounted thereon;

Fi 2 is a frontelevation thereof;

Fig. 3 is a detail perspective View of the upper bracket;

Fig. 1- is a similar bracket;

Having more particular reference to the drawings throughout which similar characview of the lower tiers of reference designate similar parts,-

this look may be stated as comprising an upper bracket connecting member 5 mounted upon the upper rail of the upper sash S of a window. Preferably, the bracket 5 is attached to the under side of the rail by means of screws or other fasteners which extend through oppositely directed fingers (3 as shown in Figure 2 of the drawing. A centrally vertically arranged substantially L-shaped hook 7 is formed with the bracket, the base portion 8 being inclined upwardly toward its free end and then extended downwardly to form a catch or stop 9, whose function will be hereinafter apparent. Formed integrally with the bracket is a depending downwardly converging wedge'member 10 which terminates at a point immediately above the end of the base portion 8 of the hook. The provision of this wedge member forms a wedge slot 10 in which the upper end of a connecting bar or rod 11 is snugly received when the sashes are to be positively held against relative movement or in an entirely closed position." a

Y This rod 11 is provided at its upper end with an opening 12 of sufficient size to loosely receive the base portion 8 of the hook and to permit movement of the extreme upper end 13 of the rod into the wedge slot when desired. The lower wall of the opening is formed to snugly engage the under face of the base portion 8 of the hook. A set of vertically spaced openings 14: is formed in the lower portion of the rod. or bar to permit connection to the lower sash through a bracket- 15 or the like.

This bracket 15 is preferably attached to the upper face of the upper rail of the lower sash by fasteners which extend through oppositely directed. ears or fingers 16. Arranged cent-rally between these fingers'and extended horizontally away from the window sash is a bar engaging finger 17. This finger 17 is tapered as shown in Figures 1 and 4 and is provided near its free end with a. relatively deep notch. or recess 18 whose function will be hereinafter set forth. A second notch or recess 19 of sub stantially one-half the depth of the first recess 18 is formed in the upper face of the linger at a point adjacent the first recess.

When the window is to be opened to the.

extent shown in Figure 2, the lower end of the connecting bar or rod is moved away from the lower bracket and through use of the bar, the upper sash is lowered or the lowersash may be raised. At the desired point, the lower end of the bar is engaged with the lower bracketas shown in full lines in Figure 1. In this position, the sashes are free to move slightly and the connection between the lower bracket and the bar is such as to permit easy separation for adjustment etc. In other words, there is a loose connection as between. the lower bracket and the bar so as to facilitate operation of the device. WVhen the sashes are positioned to entirely close the window, the bar is shifted to the dotted line position with the result that the upper end is wedged tightly in the wedge shaped notch in the upper bracket. The cross-sectional area of the finger at the point at which the second notch or recess is formed is sufficient to reliably inter-engage the bar and lower bracket, and prevent accidental disengagement. The area of each opening in the lower part of the bar is such as necessitates a certain amount of pressure upon the bar in order to shift it from the first to the second notch. The result is that accidental displacement is practically eliminated and the sashes are reliably locked.

Certain changes in the minor details of construction may be resorted to and such changes as may fall within the scope of the appended claims I consider my invention.

I claim:

1. In a. device of the character described the combination with av pair of window sashes of a bar having an opening at one end, a bracket carried by the upper sash and engageable in the opening to permit outward swinging of the bar; a bracket carried by the upper rail of the lower sash and extending beyond the inner vertical face of said sash, the upper face of the extended port-ion having a pair of longitudinally spaced notches and said bar being adapted to engage one of the notches to hold the sashes in any relatively adjusted position and at certain time to engage the other notch to positively lock the sashes against movement.

2. In a device of the character described, the combination with a pair of vertically slidable window sashes, of a substantially L-shaped bracket carried by the upper sash, a horizontally disposed notched finger car ried by the lower sash, a connecting bar having an opening near each end, the upper opening being adapted to receive the base portion of the L-shaped bracket and the lower opening being adapted to receive said finger, one wall of the lower opening being seated in one of the notches to temporarily retain the sashes in an adjusted position and to seat in a second notch to lock the sashes in closed position.

In testimony whereof, I aflix my signature.

ANDREIV J. GAYD OS.
