ADJUSTABLE SASHQ-LQCK.

SPECIFICATION forming part of Letters Patent No. 587,294, dated August 3, 1897.

Application filed September 2, 1896. Serial No. 604,643. (No model.)

To all whom, it may concern:

Be it known that I, ADEN J. ASHLEY, a

' citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Adjustable Sash-Locks, of which the following is a specification.

This invention relates to certain new and useful improvements in sash-fasteners; and

,it has for its object to provide a simple, effectview of a locking device in its unlocked position,parts of the guide-rod being broken away. Fig. 4: is a sectional view of the same, and- Fig. 5 is a similar View of a modification.

I am aware that heretofore sash-fasteners have been devised embodying the general characteristics of my invention-that is to say, such fasteners consist of a guide'rod. carried upon one sash or upon the windowframe and cooperating with a locking device carried upon the other sash, whereby the sashes may be locked in their closed position or in a partially-opened position. These prior constructions are all more or lessobjectionable, however, for many reasons, chiefly on account of their lack of simplicity and strength. Another objection to such fasten ers arises from the fact that they project from the inside of the window-sashes to such an extent as to interfere with the window-draperies and prevent the use of the ordinary roller-shade. It is the aim of the present invention not only to provide a simple and inexpensive sash-fastener, but to cure the objectionable features of prior analogous devices.

Referring more particularly to the drawings, A designates the window-frame, and B O the upper and lower sashes, respectively. The sashes are suitably guided on the win- 55 (low-frame and may or may not be provided with the usual weights and cords. The 0pposing faces of the lower and upper bars 1 2 of the sashes'B C, respectively, are oppositely beveled and form a tight joint when the sashes are in their closed positions, and the face of the sash-bar 2 is provided with a recess 3, while to that of the sash-bar 1 is secured a plate 4, having a projecting threaded socket 5, which normally extends into the re- 65 cess 3.

The upper bar of the sash B is provided with a plate 6, having a threaded projecting socket 7, similar to that upon the lower sashbar and in vertical alinement therewith, said plates and sockets being shown located intermediate the side bars of the sash or opposite same.

Supported wholly upon the upper sash B is a notched guide-rod D, having its ends screw-threaded and fitted into the sockets 5 and 7 whereby said rod is rigidly supported, and when the sashes are raised or lowered extends through the recess 3 and lies between the glasses of the sashes and out of position to be interfered with. It is to be noted, too, that the plate 4 never extends above or below the lower sash, and therefore it is impossible to get access to and remove it without first removing one of the sashes from the window-frame or removing the glass of the lower sash. Consequently it would avail an intruder nothing to remove the'top supporting-plate 6, as the rod D would still be firmly supported in the socket of the lower plate 4.

Supported upon the top of the upper sashbar of the sash O in position to cooperate with the guide-bar D is a locking device E. This locking device may be variously constructed, but I prefer to employ the construction shown on account of its effectiveness and simplicity. As shown, the locking device consists of asecuring-plate 8, provided with a head 9, from one side of which extends a vertical recess 10 for reception of the guide-barD. In the sides of the head is formed a semiannular recess 12, which intersects the vertical recess 10 and receives a segmented locking-piece 13, having a thumb-piece 14, a space 15 being left between the arms of the locking-piece sufficiently wide to permit the lateral insertion of the guide-rod in the recess 10 when said space is in alinement with the recess, and when in this position the guide-rod is unlocked and either sash may be raised or lowered, as desired. If, however, the lockingpiece be shifted to the rightor left of the above-described position its inner face enters one of the notches in the opposing face of the guiderod and prevents the longitudinal movement of the rod in the vertical recess.

While in Figs. 1 to atI have shown the guiderod as provided with notches, it will be understood that they may be omitted and the friction between the contacting surfaces of the locking-piece and guide-rod be alone dopended upon to lock them together, as shown in Fig. 5. It will be obvious, also, that the locking -piece may be in the form of a ring instead of a segment and that other similar modifications may be made without departing from the spirit of the invention.

From the above description it will be seen that when the window-sashes are in their closed locked positions, as shown in Fig. 2, no movement whatever is permitted them. \Vhen, however, a sash is partially raised or lowered and then looked in such position, the sashes may be moved simultaneously up or down, accordingly as the window is open at the top or bottom, for a distance equal to the width of the opening; but they may not be moved independently of one another, and therefore it is impossible for an intruder to open the window sufficiently to effect an entrance.

Vhat I claim is 1. In a sash-fastener, the combination with a guide-rod supported upon one window-sash, of a locking device cooperating with the guiderod, said locking device comprising a head having a vertical recess for reception of the guide-rod and an intersecting horizontal segmental recess, and alocking-piece embracing the head having a rotary reciprocating movementin the horizontal recess and adapted to be moved into and out of engagement with the guide-rod, substantially as described.

2. In a sash-fastener, the combination with a guide-rod supported upon one window-sash,

of a lockin g device cooperatin g with the guide-' rod, said locking device comprising a head having a vertical recess for reception of the guide-rod and an intersecting horizontal segmental or forked recess, and a segmentallocking-piece embracing the head received in said horizontal recess and adapted to reciprocate therein the arms of said locking-piece being left separated, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ADEN J. ASHLEY.
