' acter designed to hold a window sash at various elevations.
The general ob ect of my invention is the provision of a sash lock of this character So.
constructed and arranged that the window may be opened to various heights and locked in position and it will be practically impossible for any one outside the window to release the lock and raise the window any farther.
A further object of the invention is the provision of a very simple, cheaply made, and easily operated device of this character which may be applied to all ordinary windows and hold the window sashes positively in adjusted position.
Other objects will appear in the course of the following description. 7
My invention is illustrated in the accorn panying drawings, wherein- Figure 1 is a face view of a portion of the window frame and sash with my improved locking device applied thereto; Fig. 2 is a side elevation of the frame and a sectional. view of the sash showing my invention in elevation Fig. 3 is a section on the line '38 of Fig. 1 Fig. 4 is a detail view of the latch; and Figs. 5 and 6 are plan views of diiferent forms of rod holders.
Referring to these drawings, A designates a window frame and B the lower "ash thereof. Mounted in any convenient position upon the window frame are the upper and lower supporting brackets 10 and 11. These are firmly attached to the window casing or frame and support between them a vertical rod 12, preferably cylindrical in cross section and about three-eighths of an inch in diameter. This rod is notched at intervals as at 13. Mounted upon the window sash B is a bracket 14 which bracket is so formed to provide a base through which attaching screws 15 pass and provide a portion which arches over the rod 12 as at 16. At its end the bracket is angularly bent as at 17 to provide a face or portion extending transversely of the rod 12 and pivoted upon this "hat portion 17 1s a latch 18 having a detent tooth 19 and a finger piece 20. This latch is pivoted upon a pivot screw or lock member 21 so that the latch rotates in a vertical plane. The detent tooth 19 is adapted to engage in any one of the notches 13 when the latch is turned into a vertical position parallel to the rod 12, but is shifted out of enagement with the notches 13 when the latch is rotated against the force of the spring 22. A stop lu 23 is formed upon the latch adjacent the finger piece which limits the rotation of the latch under the action of the spring.
In Figs. 5 and 6 I show two forms of the holders 10 and 11. The form illustrated in Fig. 5 and designated 10 is intended to be used on window frames that have a stop to hold the window sash, whereas the member 10 is intended to be used on straight window frames that have no stop to hold the sash.
The operation of this device will be evident from what has gone before. Its advantages reside in the fact that the window can be opened to any height wanted, the latch adjusted and then the window sash cannot be opened wider from the outside of the house. Thus the house may be left with one or more of its windows open and yet these windows cannot be opened any farther from the outside of the house. The win (lows may be left open at night and burglars cannot enter by opening the window any farther. This improved latching device or look therefore provides a protector and it also may be used in place of weights as it will hold the window at any height desired. It will be obvious of course that the rod 12 maybe extended the full length of the *indow sash or the full length of the upper and lower sashes as desired but I have illustrated the rod 12 as being relatively short and disposed slightly above the upper end of the lower sash when the lower sash is closed.
My invention is simple, cheaply made, may be readily put in place and is entirely effective in use.
Having described my invention, what I- mounted in said brackets and having spaced horizontal notches, a bracket mounted upon the Window sash and having a portion extending outward and laterally transversely of the outer face of the rod, an angular latch pivoted-upon said bracket for movement in a vertical plane parallel to the face of the Window sash and frame andhaving a detent on its lower end engageable in any one of said notches, and a finger piece on the other end, a spring normally urging the latch in 2:
direction to carry its detent into engagement with the notch in the rod and a stop limiting the movement of the latch under the action of thespring to a position Where the detent isin' a horizontal plane.
In testimony whereofI hereunto afiix my signaturein the presence of two Witnesses ALBERT C. CHRISTENSON.
