UNITED STATES GEORGE S. HALSE, OF LONG BEACH, CALIFORNIA.

WINDOW FASTENER.

Application filed July 13,

To all whom it may concern:

Be it known that I, GEORGE S. HALSE, a citizen of the United States, residing at Long Beach, in the county of Los Angeles and State of California, have invented new and useful Improvements in Window Fasteners, of which the following is a specification.

My invention particularly pertains to a fastener for windows of the double vertically slidable sash type, and the object thereof is to provide a fastener which is adapted to lock a pair of slidable window sash together in either a closed or apartly open position.

Another object is to provide a window sash fastener of such character that a pair of window sash may be connected together in a partly open position so as to afford a ventilation space either above the upper sash or below the lower sash and which fastener is so constructed as to render it difficult for a person to unlock the fastener from exterior of the window as by manipulating a wire or similar implement through the open space of the window.

A further object is to provide a window sash fastener which is so constructed that the parts may be readily formed and assembled whereby it may be produced at small cost.

With the foregoing objects in view, together with such other objects and advantages as may subsequently appear, my invention resides in the parts and in the construction, arrangement and combination of parts, hereinafter described and claimed and illustrated in the accompanying drawing, in which 2- Figure 1 is a view in elevation of a double hung window of the vertically slidable sash type showing the fastener as applied to lock the sash in a closed position.

Fig. 2 is a view similar to Fig, 1, showing the fastener as employed in securing the sash in a partly open position.

Fig. 3 is a detail in vertical section as seen on the line 33 of Fig. 1, showing the fastener construction.

Fig. 1 is a view in perspective of the fastener bolt.

Fig. 5 is a view in perspective of the fastener base.

Fig. 6 is a perspective view of the fastener cover.

More specifically, 7 and 8 indicate the 1923. Serial No. 651,379.

upper and lower sash of a window which are mounted to slide vertically in a window frame 9 in the ordinary manner. In ca-rr mg out my invention I provide a keeper plate 10, which is secured to the front face of the interior side of one of the side rails or stiles 11 of the upper window sash 7. The plate 10 is preferably counter-sunk in the stile 11. Formed on the plate 10 is a pair of outwardly projecting horizontally extending flanges l2 and 13 which are spaced apart a suitable distance according to the extent to which it is desired to fasten the sash relative to each other in a partly open position as will later appear. The

flanges

12 and 13 are designed to be engaged by a bolt 14: carried by the lower window sash 8; the bolt being arranged to extend transversely of the top rail of the lower window sash, and the flange 12 being so positioned relative to the bolt that the latter will engage the under side of the flange 12 when the window is closed as shown in Figs. 1 and 3, so as to lock the sash against movement relative to each other. The upper flange 13 is designed to be engaged by the bolt 141 when the window sash are partly open as will be later described.

The bolt 14; comprises a flat metallic bar formed as shown in Fig. 4:, being provided with a head portion 15 at one end and a stem portion 16 at its other end, there being shoulders 17 between the head 15 and stem 16. The head 15 is formed with horizontally extending upper and

lower edges

18 and 19, and has a vertical end wall 20 which is cut away to form an incline face 21 leading from the lower edge 19 of the bolt as is common in latch construction. A shoulder 22 is formed on the under side of the bolt between the shoulder 17 and the incline face 21 and projecting from the side of the bolt is a lug 23 located between the shoulder 22 and the incline face 21. The bolt 14 is supported in a casing comprising a base plate 24 and a cap 25 particularly shown in Figs. 5 and 6. The base plate 2 1 is formed with a pair of upstanding flanges 26 and 27 at its ends, which flanges are spaced apart to provide slots 28 and 29 to receive the bolt 14 in which the latter is slidable. In assembling the fastener the bolt is placed in the slots 28 and 29 with the lug 23 on the bolt abutting against one of the flanges 26 so as to limit the outward movement of the bolt; a helical spring 30 is wound around the stem 16 and bears between the shoulder 17 on the bolt and the flanges 27 so as to normally maintain the bolt in its advanced position. The outer end of the stem 16 projects horizontally through the slot 29 and has its side faces milled as indicated at 31 so that the stem may be readily grasped by the fingers and retracted in opposition to the spring 30. As a means for limiting retractive movement of the bolt the plate 24 is formed with an upstanding lug 32 which projects in front of the shoulder 22 and acts as a stop.

The cap 25 embodies a top plate 33 and side walls 34 and 35, which side walls are formed with lugs 36 on their lower edges adapted to pass through perforation 37 in the base plate 24 and to be riveted on the under side of the base plate to effect engagement between the cap and base. The sides 34 and 35 of the cap are designed to abut against the edges of the flanges 26 and 27 on the base member; the ends of the side members 34 and 35 terminating flushed with the outer faces of the flanges.

As a means for preventing the stem 16 being manipulated from the exterior of the window the top 33 of the cap is formed with an extension 38 which projects horizontally over the outer end portion of the stem 16 as particularly shown in Fig. 3; the extension 38 constituting a guard to prevent engagement of the stem from above.

In the operation of the invention when the

sash

7 and 8 are in their closed position as shown in Fig. 1 the bolt 14 will project beneath the flange 12, thereby holding the sash against movement relative to each other. When it is desired to open the window the bolt 14 is retracted in opposition to the spring 30 so as to withdraw it clear of the flange 12. When it is desired to lock the window sash in a partly open position the bolt 14 is released after the upper sash has been moved such distance that the flange 12 will be disposed beneath the outer end of the bolt so that the outer end of the bolt 14 will project immediately beneath the flange 13. The upper sash 7 will then be fastened against downward movement relative to the lower sash and the lower sash will be held against upward movement relative to the upper sash. The upper sash will then be disposed in a partly open position. as shown in Fig. 2, thus providing a ventilating space at the top of the window.

If it is desired to provide a ventilating space at the lower part of the window the two sash may be raised so as to close the upper sash and partly open the lower sash. The sash will then be fastened against opening movement relative to each other but are free to be moved to a closed position as the flange 12 in moving against the inclined face 21 on the end of the bolt will retractthe latter so that the bolt may pass the flange 12 and be re-engaged with the under side thereof.

lVhen it is desired to open the window the bolt 14 is held in a retracted position until it is disposed above the flange 13, whereupon the sash may be moved freely relative to each other.

The bolt is so mounted and arranged that when in its fully advanced position its outer end will be spaced from the stile 11 so as not to mar the surface of the stile, on movement of the sash relative to each other.

I claim 1. In a window fastener, the combination with an upper and lower sash of a double hung window, of a keeper plate mounted on the upper sash, a plurality of spaced ribs on said plate projecting beyond the surface of the sash, a reciprocal spring pressed bolt carried on the lower sash having one end adapted to project beneath the flanges on the keeper plate, and arranged with said end normally spaced from the face of the upper sash, a stem projecting horizontally from said bolt and a guard extending horizontally over said stem.
