T 60 whom it may concern:

Be it known that I, JAMEs J. GIER, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented new and useful Improvements in Window- Locks, of which the following is a specification.

My invention has relation to sash-fasteners; and its primary object is to produce a cheap, durable, and efficient device of this character which will lock a window against surreptitious opening and at the same time clamp the meeting-rails of the sashes together to exclude air and prevent rattling.

Afurther object of the invention is to provide a sash-fastener which may be readily and quickly adjusted to compensate for any irregularities in the sashes.

The invention consists of the construction, combination, and arrangement of parts hereinafter fully described, claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a view in elevation of a fragmentary portion of two sashes, showing my improved sash-fastener in applied position thereon. Fig. 2 is a longitudinal sectional view on the line 2 2, Fig. 1. Fig. 3 is a transverse sectional view on the line 3 3, Fig. 1. Fig. 4 is a top plan view of the blank from which the base-plate isformed. Fig. 5 is a similar view of the blank from which the latch is constructed.

Referring to the drawings by referencenumerals, 1 and 2 designate, respectively, the meeting-rails of the upper and lower sashes of a window, and 3 the stile of the upper sash. The stile 3 has secured thereto a base-plate 4, which has pivotally mounted thereon a latch 5, adapted to be swung to engage a keeper 6, carried by the rail 2, whereby the sashes are locked against movement in their frame and clamped together to exclude air and prevent rattling. The baseplate is preferably struck up from a single piece of metal rectangular in contour and having one of its edges slitted to provide lips 7 and a tongue 8, located therebetween. The lips 7 are rolled or bent upon themselves to form hinge-barrels 9, and the plate is bent at a point near its transverse center to provide flanges 10 and 11 to embrace the stile 3. The flange 10 and tongue 8 are provided with elongated apertures 12, throughwhich screws or other fastening means pass to secure the base-plate in applied position. The elongated apertures 12 permit the base-plate being adjusted to compensate for any irregularities in the sashes. The keeper is secured in applied position by any suitable fastening means, and it is provided with cam-face 6 and a flange 6 also having a cam-face. The latch is also struck up from a single piece of any suitable metal, and one end thereof is reduced and provided with a head 13, having a downwardly and rearwardly extending lip 14., which is adapted to engage the flange 6 of the strike-plate to lock the sashes against movement. The rear or opposite end of the latch is rolled to provide a hinge-barrel 15, adapted to be secured between the hinge-barrels 9 by means of a pintle 16, which mounts the latch upon the strike-plate to have a horizontal swinging movement, whereby it may be caused to engage and disengage the keeper 6. '1 he cam-face of the flange 6 causes the meeting-rails to approach each other when the catch is swung to bring the lip 14 into engagement with said flange. The latch is provided at a point intermediate its ends with a depending arm 17, adapted to lie in engagement with the meeting-rails at their points of contact when the catch is swung to engage the keeper to relieve the lip 14 of any strain that may be brought to bear thereon when any unauthorized attempt is made to open the window.

It is apparent that through virtue of the cam-face of the flange 6* the meeting-rails of the sashes will be caused to engage each other to exclude air, prevent rattling, and lock the sashes in their frames and that the arm 17 will relieve the lip 14 of all strain. It

is further apparent that tlnough virtue of the elongated slots 12 the base-plate may be adjusted vertically in order to compensate for any irregularities of the sash in order that the catch may be swung to engage the keeper. This adjustment may be accomplished without removing the base-platc from applied position, as the base-plate is left free to be moved by simply loosening its fastening means.

The latch is adapted to be held in engagement with the base-plate by means of a lever 17, which is pivotally mounted upon the rail 2 to be swung into engagement with the latch, as clearly illustrated in Figs. 1 and 2.

The construction of the base-plate from a single piece of rectangular metal and the latch from a single piece of metal provides a sash-fastener which is simple, easy, and cheap of construction.

When a window is provided with sashes each having but one pane of glass, two of my improved fasteners are used, the base-plates being secured to each of the stiles of the upper sash; but when the sashes are provided with more than one pane of glass only one of these devices is used, and in this instance the base-plate is secured to one of the panestrips of the upper sash.

Having thus described the invention, what is claimed as new is A sash-lock comprising a base-plate having one end slitted to provide hinge-bearings and an interposing flange provided with an the plate, and a keeper having a cam-face provided with an overhanging flange to connect with the lip, substantially as specified.

In testimony whereof I afliX my signature in presence of two witnesses.
