To @ZZ whom t may concern.-
Be it known that I, FRANKLIN O. ANDREWS, a citizen of the United States of America, residing at Vl/Iilloughby, -in the county of Lake and State of Ohio, have invented certain new and useful Improvements in Sash-Locks; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.
This invention relates to improvements in sash-locks.
rl`he object of this invention is to provide a sash-lock which is applied to the upper sash of a window and which is arranged and secured in place in such a manner that it cannot be loosened or rendered inoperative by wedges or tools applied in under the lower end of the lower sash to force the lower sash upwardly.
With this object in view and to the end of realizing other advantages hereinafter appearing this invention consists in certain meritorious features of construction and combinations of parts hereinafter described, and pointed out in the claims.
In the accompanying drawings, Figure l is a side elevation of a portion of the adjacent portion of the two sashes of a window. Fig. 2 is a vertical section on line 2 2, Fig. l, looking in the direction indicated by the arrow. Fig. 3 is a vertical section corresponding with Fig. 2, except that in Fig. 3 the sash-locking stop of the sash-lock is shown in its operative position, whereas in Fig 2 the said stop is shown in its inoperative position.
Referring to the drawings, A designates a portion of a window-casing; B, the upper sash; D, the lower sash; I), one of the stiles or side members of the framework of the upper sash, and d the framework of the lower sash.
My improved sash-lock comprises a metal case G, which occupies a recess made in the inner side of the stile or side member b of the framework of the upper sash. The case Gr is provided with an upwardly-projecting ear 6 and a depending ear 7, arranged at the upper end and lower end, respectively, of the case Gr. The ears 6 and 7 are each provided with a horizontally-arranged hole 8, which extends horizontally through the respective ear and is countersunk at its outer end to receive the countersunk head /t of a screw H, which extends through the said hole and is screwed into the stile o. It will be observed, therefore, that the case Gr is removably secured to the framework of the upper sash by screws which are screwed horizontallylinto the said framework from the inner side of the said sash. The case Gr is arranged with its ears 6 and Hush with the inner side of the upper sash, so as to avoid interference with the movement of the lower sash.
Vithin the chamber g of the case G is arranged a stop K, which is pivoted at its upper end to the case Gr, as at 7c, horizontally and at a right angle to the screws I-I. The stop K is capable therefore of swinging in a vertical plane and extends from the upper end to the lower end of the chamber g of the case Gr. The chamber g is open at its forward sidethat is, at the inner side of the upper sashto accommodate the swinging of the stop K forwardly over the upper end of. the lower sash when the latter is in its lower position, and the stop K is operative or inoperative according as it is in its forwardly-swung or rearwardly-swung position.
The arrangement of the parts is such that the stop K in its rearwardly-swung position is contained wholly within the chamber g of the case Gr and in its forwardly-swung position overlaps the upper end of the framework of the lower sash. rlhe arrangement of the case G relative to the lower sash is preferably7 such that the bottom wall of the chamber g of the said case is flush with the upper edge of the framework of the lower sash in the lower position of the said sash when the sashes are closed.
The lower edge of the stop K extends concentrically of the axis of the stop, and the upper end of the stop has such arrangement relative to the top wall of the chamber g of the case Gr that the said end of the stop in the forwardly-swung and operative position of the stop abuts against the top wall of the said chamber and prevents any strain upon the pivot 7c by an attempt to lift the lower sash when the stop is in its operative position.
Preferably the upper rail or top member roo IIO
wall of a recess 10, formed in the inner side of the stop.
Means for locking the stop K in its rearwardlyswung and inoperative position is provided and comprises a latch R, which is pivoted, as at fr, horizontally and parallel with the axis of the stop K and projects rearwardly. The latch R is provided at its rear and free end with an upwardly-projecting member 12. rlhe latch R is provided at its forward and pivoted end with an upwardly-projecting arm 13, which is arranged longitudinally of the stop K. The stop K is suitably slotted, as at 14, to accommodate the location and operation of the latch R and its arm 13. The rear Wall ofthe case Gr is slotted, as at 15, to accommodate the extension of the latch R through the said wall and to accommodate the operation of the latch. The arrangement of the parts is such that in the rearwardlyswung and inoperative position of the stop K the latch R extends through the rear wall of the case Gr, and the upwardly-projecting member 12 of the said latch overlaps the exterior of the said wall, and the stile of the framework of the upper sash is cut away exteriorly of the said wall, as at 16, to accomrnodate the location and operation of the latChR.
A suitably-applied spiral spring Q, acts to retain the latch R in its operative position, wherein the upwardly-projecting member of the said latch, as already indicated, overlaps the exterior of the rear wall of the case G. The spring Q, is confined, preferably, between the inner side of the arm 13 and the rear wall of the case G, and the stop K is provided with a hole 17, which extends rearwardly through the stop from the upper portion of the slot 14 to accommodate the location and operation of the said spring.
The upwardly-projecting member 12 of the latch R is beveled, so as to form an incline 18 upon the rear side of the said member, which incline slopes upwardly and forwardly.
By the construction hereinbefore described it will be observed that the latch R in the rearwardly-swung and operative position of the stop K locks the said stop in the said position, and that by pressing` rearwardly against the forward side of the arm 13 of the latch R against the action of the spring Q to disengage the projecting member 12 of the'said latch from the exterior of the rear wall of the case Gr the stop K is rendered free to swing forwardly and is then at once swung forwardly by the action of the spring L.
To actuate the stop K from its forwardlyswung and operative position into its rearwardly-swung and inoperative position, it is only necessary to actuate the said stop by pressu re exerted upon its forward side rearwardly against the action of the spring L until the upwardly-projecting member 12 of the latch R is brought exteriorly of the rear wall of the case G. The incline 18 upon the said member 12 during the actuation of the stop K into its inoperative position comes into engagement with the top wall of the slot 15 in the rear wall of the case Gr, whereupon the latch R is depressed against the action of the spring Q, to accommodate the passage of the latch member 12 through the said slot until the said latch member is brought exteriorly of the said wall, whereupon the said spring acts to swing the latch upwardly to cause the latch member 12 to overlap the exterior of the rear wall of the case, and thereby lock the stop K in its rearwardly-swung and operative position.
