BARNEY MURPHY, OF NEW HAVEN, CONNECTICUT, ASSIGNOR OF ONE- HALF TO HENRY P. DOWNES, OF NEV HAVEN, CONNECTICUT.

SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 695,327, dated March 11, 1902.

Application iled December 23,1901. Serial No. 86,388- `(No model.)

To all whom, t may concor/7e:

Be it known that I, BARNEY MURPHY, of New Haven, in the county of New Haven and State of Connecticut, have inventeda new and useful Improvement in Sash-Fasteners; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a broken perspective view of parts of a window frame and sashes with my improved sash-fastener applied thereto; Fig. 2, a sectional view with the sashes looked in their normal position; Fig. 3, a similar view with the bolt in its retired position; Fig. 4, a similar View showing the cam-leverin engagement with the rack; Fig. 5, a top or plan View of the fastening device.

This invention relates to an improvement in y sash-fasteners, and particularly to that class which includes a rack and a locking device whereby the sashes may be locked in various positions, so as to permit the lower sash to be partly raised and the upper sash to be partly lowered and locked in such positions, the objectof the invention being a simple arrangement of parts whereby the device is substantially automatic in its action; to provide a means for preventing the sashes from rattling and one which may be adjusted to compensate for shrinkage of the sashes or other inequalities; and the invention consists in the construction and arrangement of parts, as will be hereinafter described, and particularly recited in the claims.

The device consists of a case 2, herein shown as substantially rectangular for convenience of application and provided with a flange 3 by which thedevice may be secured to the top rail 4 of the lower window sash As herein shown, the window-sash is recessed to receive the case 2 5 but it is apparent that the .l

case might project upward above the top of the sash, if desired. Within the caso is a bolt 5, to which a screw 6 is connected and so as to extend rearward therefrom through a partition 7 in the case, and on this screw is a spiral spring 8, the tendency of which is to throw the bolt forward. The central portion of the outer end of this bolt is out away, leaving fianges 9 on opposite sides of a central beveled portion 10, the upper edge 1l of which is adapted to engage with a rack 12, secured to the upper sash 13. Upon the top of the bolt is alu g lhwhich projects upward through a clearance-slot 15 in the top of the case. To this lug 14 a cam-lever 1G is pivoted, the end of which projects rearward and has on its under face a rib 17, adapted to engage with the edge of the case and so as to hold the bolt in its retired position, as shown in Fig.. 3. This lever 16 I have termed a cam-lever, for the reason that in addition to its use as a means for withdrawing alocking-bolt it may be employed as an antirattling device or a device to hold the sashes in their fully-closed positions. The position of the rack 12 is such that when the sashes are closed the end of the bolt 5 passes beneath its lower end, as shown in Fig. 2; but should there be a little play the lever 16 may be raised so as to force its nose 18 beneath the second tooth 19 of the rack, which by the downward movement of the upper end of the lever will be lifted, as shownin Fig. 4:, the endpof the lever being then passed beneath a hook 2O of a catch 21, which is arrangedat one side of the case 2, which catch'holds the lever 1G depressed, as shown in Figs. Lfand 5. To open the sashes, the bolt is drawn backward by means of the cam-lever 16, and in order to insure its being in position to engage with the rack when the sashes are closed a dog 22 is hung in the window-frame and so as to extend into the path of the said cam -lever 16. This dog is free to turn upward, so that the lever may pass it without obstruction; but it is held against downward movement, so that as vthe lower sash is drawn down this dog will lift the end of the lever and disengage the rib 17 from the edge of the case, so as to permit the bolt to youtward under the action of its spring, and thus be in position to engage either of the teeth on the rack 12. When thus engaged, the lower sash can be pressed downward as the bolt will ride over the inclined teeth of the rack; but it cannot be raised nor can the upper sash be lowered until the bolt has been withdrawn. The obIl IOO ject of employing a screw as thetail of the bolt is to provide for adjusting the throw of the bolt. The object of permitting the ends of the bolt to extend on opposite sides of its operating-face is that those iianges prevent the introduction of a blade of any character by which the bolt might be thrown.

The operation of the device will be clearly understood from the foregoing description of its construction. The bolt is readily withdrawn by the cam-lever and locked in its withdrawn position, from which position it is tripped when the sash is lowered through the medium of the dog 22. If thelever is used as a cam to force the upper sash upward or the lower sash downward, and hence add to the security of the device as a lock, it will be held in this position by the latch 21, a limited amount of play being allowed at the rivet by which the latch is connected with a bolt t0 permit it to be turned slightly to one side, as indicated in Fig. 5.

Y Having thus described my invention, what I claim as new= and desire to secure by Letters Patent, is-

l. A sash-fastener comprising a case, a bolt longitudinally movable therein, a lever arranged above the case and pivotally connected with said bolt and having a transverse rib on its under side adapted to engage with the edge of the case to lock the bolt iu its retired position, and means secured to the upper sash of the window on which the bolt is adapted to engage, substantially as described.

whereby the bolt may be locked in its retired position, a rack and a dog adapted to trip the said lever substantially as described.

3. In a sash-fastener, the combination with the case, of a b'olt longitudinally movable therein, a cam-lever secured to said bolt and having a forwardly-projecting end, a rack with which said bolt and lever may be engaged and means for holding the lever in a depressed position substantially as described.

4. In a sash-fastener, the combination with the case of a bolt longitudinally movable therein, the forward end of said bolt centrally cut away forming an inclined surface and flanges on opposite sides thereof, a lever pivotally connected with said bolt whereby the bolt may be retired and locked in its retired position, and a rack with which said bolt may be engaged when released by the lever substantially as described.

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