WILLIAM A. BAY, OF OAKLAND, CALIFORNIA WINDOW-FASTENERi Specification of Letters Patent.
Patented Aug. 26,1913.
Application filed May 6, 1913. Serial No. 765,976.
To all whom it may concern:
Be it known that I, WILLIAM A. RAY, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in Window-Fasteners, of which the following is a specification.
This invention relates to window fasten- 'ers.
It is an object of the present invention to provide a window fastener adjustable in one position to ermit the sashes to be moved relatively for a hmited distance and for such an amount that it will be impossible for persons to climb over or under the open sashes, and which device is further adjustable to clear the window sashes when so desired.
A particular object of the invention is to provide a window stop involving details of construction designed to insure the protection of the device against picking or unwarranted adjustment.
A further object is to provide means for preventing the rattling of the window sashes when adjusted in open position.
The invention consists of the parts and the construction and combination ofparts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 1s a front elevation of the device as applied to the inside of a window sash. Fig. 2 is a vertical section through the casing of the stop, showing the parts in elevation. Fig. 3 is a front view of the fastener or stop with the pawl or latch depressed into the casing.
In the drawings there are represented upper and lower sashes 2 and 3 respectively. On the meeting rail of the lower inner sash there is provided a striking plate 4. Upon the inner surface of one of the stiles of the upper sash 2 there is readily attached the flange or lap plate 5 of a stop or latch casing 6, having a recess, box or chamber 7 at one edge which is adapted to project toward the plane of the glass 8 of the upper sash when the flange 5 is screwed or otherwise secured tothe surface of the stile of the sash.
The latch casing 6 may be secured at any desired position vertically along the stile of the sash 2 and is provided with a stop, latch or dog9, turnable upon a pivot or screw 10 between friction washers 11 bearing on the sides of the casing 6. The thickness of the stop or latch 9 is somewhat less than the width of the chamber 7 of the latch casing so as to permit the latch and a locking slide 12 mounted thereon to be swung from a vertlcal position, Fig. 2, about the pivot 10 to a lowermost concealed position, indicated in Fig. 3, when being depressed into the chamher 7 of the casing 6.
The swinging end of the stop or latch 9 is provided with a shoulder 13 against which is movable the lug or projection 14 of the slide 12 slidable along the latch 9. When the latter is turned into vertical position above the pivot 10, the outwardly projecting movable lug 14 on the latch 9 will project into the path of movement of the striking plate 4 on the lower inner sash 3 when the sash 3 is moved upwardly. The edge of the striking plate also engages the inclined surface 15 of the latch or dog 9 and thus presses the latter outwardly toward the light or glass 8 and compresses a spring 16 mounted in the chamber 7 of the casing; the reaction of the spring upon the dog 9 acting to yieldably spread or separate the two sashes just sufficiently to prevent the rattling of same by wind pressure or other causes.
When the stop piece 14 of the sliding part 12, which embraces the body of the latch 9, is moved outwardly along the latch 9 and pushed into the chamber 7 at its upper portion, the pressure of the walls of the casing 6, upon the slide 12, effects the temporary holding of the same in the upwardly adjusted position at which it is effective to limit the upward movement of the inner sash 3 or the downward movement of the outer sash 2 beyond the predetermined distance from the striking plate 4 to the lug 14. The walls of the casing may be braced at the upper end by a transverse tie, arm, or other suitable device 17, at the upper end of the casing 6, the bottom of which is shown as inclined.
The spring 16 is secured to the bottom of the casing, intermediate its ends, by a rivet 16 and its lower leaf is in constant engagement with the squared, pivoted, adjacent end of the pawl 9, the function of this engagement being to yieldably hold the pawl in its vertical and pendent positions. The bottom of the box or casing is depressed, as at 16', for clearance space for the lower end of the spring and the upper end of the bottom of the chamber is struck in to form a dead-stop to prevent the pawl being depressed so far as to allow the sashes to clear.
Should for any cause the pawl and its slide 12 he accidentally released and swing downwardly to the dotted line position, Fig. 2, then the lug 14 would drop against the bottom of the chamber 7, as indicated. Upon upward or downward movement of the sashes the striking plate would encounter the depending end of the latch 9, and during the continued relative movement of the w sashes the pawl 9 would be automatically turned to its effective stopping position.
In the event that it becomes desirable to move the sashes 2-3 a greater distance than the interference of the latch and its asso- 15 ciated device 12 would permit, then the latch or stop 9 may be swung downwardly about its pivot 10. The operator then slides the slidable device 12 along the dog or latch 9 until an index part or edge 18 of the slide 20 on the back of the pawl 9 would register with an index mark or nick 19 on the back at the pawl, whereupon the operator could then press the latch and its slide into the chamber 7 of the casing 6 and the lug or projecting portion 14c of the slide 12 would enter an aperture 20 formed for its reception in the bottom of the chamber 7 and permit the depression of the pawl 9 and the slide into the chamber to such a degree that the sash 3 could be moved vertically without interfering with any projecting portion of the fastening or stop device.
For retaining the pawl 9 and slide 12 temporarily but firmly depressed in the chamber 7 of the latch casing, a suitably shaped spring 21 is attached to the lap flange 5 and has a tongue 22 projecting into and obliquely across the chamber 7, Figs. 1 and 2, so as to encounter the lug 14; of the slide 12 when the latter is depressed into the chamber 7 for insertion through the aperture 20 of the chamber 7.
The upper and lower edges of the aperture 20 in the bottom of the chamber 7 are 5 formed with inwardly turned teeth or projections 23, the function of which is to retard the registration of the stop slide 12 with the aperture 20, except when the slide is carefully registered with the index notch 19 on the back of the latch 9, thus tending to make the device secure against surreptitious adjustment or picking by unauthorized persons from the outside of the window. The outer face of the stop projection lt is preferably serrated, as at 24:. These serrations are readily engageable with the teeth or lips 23 of the aperture 20 to prevent the upwardly sliding movement of the slide 12 when in the depending position shown in the dotted lines, Fig. 2, as would occur by the pressure of a wire or other implement. It is only by the accurate registration of the index device 1S--19 on the latch.
9 that the projection 14: would be brought into registration with the clearance pocket chamber 7. ward to prevent the slide lug 14L from being or aperture 20 through which the projection let will extend when the latch 9 is depressed in the chamber 7.
Below the aperture 20, which is formed for the reception of the projection 14 and the slide 12, there is formed another aperture or pocket 25 into which will project the shoulder 13 of the latch 9 when the latter is swung downwardly and depressed in the The spring 21 also acts as a readily slid into position with the aperture 20, and also requires the application of some little pressure on the slide before it will enter the pocket. The side wall of the casing 6, opposite the flange 5, serves not only to cover the pawl, but also supports the end of the pivot 10, and furthermore prevents the pawl from being bent transversely over toward the plane of the sash.
Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. A fastening device attachable to a win- I dow sash and adapted for'adjustment in one position to prevent movement of window sashes beyond a predetermined amount and adjustable in another position to clear said sashes, said device comprising a casing attachable to one of the sashes and having a chamber, a pawl or stop turnable into an uppermost position to project into the path of movement of the opposite sash and depressible when in the lowermost position into the casing to clear said sash, and a slide mounted on the pivoted stop for preventing the accidental entrance of the stop into the casingv 2.
