SASH-FAST'ENER.

SPECIFICATION forming part of Letters Patent N0.'758,416, dated April 26, 1904.

Application filed December 8, 1903. Serial No. 184,306. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK B. GEAPP, a citizen of the United States, residing at Ke. nosha, in the county of Kenosha and State of Wisconsin, have invented new and useful Improvements in Sash-Fasteners, of which the following is a. specification.

My invention relates to new and useful Improvements in sashfasteners; and its object is to provide a simple, durable, and inexpensive device which can be securely fastened to a window-sash and which is adapted to project into the path of another sash, and thereby prevent the sashes from being raised or lowered.

Another object is to provide means whereby the lock can be automatically removed from locking position by the depression of a button.

With the above and other objects in View the invention consists in providing a slotted casing having a locking-bar pivoted therein and adapted to project therefrom. This bar is adapted to hang by gravity within the easing and is provided with a locking device whereby the same can be held when projected from the casing.

The invention also consists in providing the bar-securing device with a push-button, whereby the bar can be released when it is desired to unlock the sashes.

The invention also consists in the further novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, showing the preferred form of my invention, and in which Figure 1 is a front elevation of my improved I lock and its casing. Fig. 2 is a similar view thereof with the face-plate of the casing removed; and Fig. 3 is a section on line 3 3,

Fig. 2. v

Referring to the figures by numerals of reference, 1 is a preferably rectangular casing locking-bar 5 above the lower sash.

through said slot, and when in this projected position the inner ends of the locking-bar rest upon the lug 2, before referred to. A block 6 is formed within the casing at one end, and secured upon this block is a spring lockingstrip having a stem 8 projecting therefrom and through an aperture 9, formed Within the face-plate. It will be understood that the locking-bar 5 normally hangs by gravity within the slot 3 and easing 1.

When it is desired to lock the two sashes together, the upper end of the locking-bar is pressed inward and the lower end grasped and drawn upward, so as to swing the inner end of said bar under the end of the strip 7 which will spring thereover and hold it in position on the lug 2. The locking-bar will then project into the path of the adjoining sash, and therefore neither of said sashes can be moved longitudinally except for a distance equal to the distance from the locking-bar 5 to the end of the adjoining sash. When it is desired to release the sashes, the stem 8 is pressed inward, so as to remove strip 7 from bar 5, and said bar falls by gravity through the slot and into the casing and out of the path of the sash.

It will be seen that this sash-fastener is very simple in construction and can be readily attached to any form of sash ordinarily used.

While it is preferably connected to one of the."

sashes, it can, if desired, be secured to the window-casing in such position as to bring the This a1- rangement is especially desirable where the upper sash is immovable.

In the foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and I therefore reserve the right to make such changes as fairly 1 fall within the scope of my invention.

Having thus described the invention, what is claimed as new is 1. In a sash-fastener, the combination with a casing having a supporting-lug therein; of a locking-bar pivoted within the casing and adapted to project therefrom and bear upon the lug and a holding-strip within the casing and adapted to bear upon the locking-bar and hold it in extended position.

2. In a sash-fastener, the combination with a casing having a supporting-lug therein; of a locking-bar pivoted Within the casing and adapted to project therefrom and bear upon the supporting-lug, a spring holding-strip secured within the casing and adapted to bear IO upon the locking-bar and hold it in projected position, and a releasing-stem projecting from the holding-strip.

3. In a sash-fastener, the combination with a casing having supporting means therein; of a pivoted locking-bar adapted to bear upon the supporting means and to project from the casing, and a holding device adapted to automatically lock the bar in projected position.

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