LEWIS C. l/VALKER, OF INDIANAPOLIS, INDIANA.

FASTENER FOR THE MEETING-RAELS'OF SASHES.

SPECIFICATION forming part of Letters Patent No. 472,088, dated April 5, 1892. Application filed December 31, 1891. Serial No. 416,735. (No model.)

To all whom it may concern.-

Be it known that I, LEwIs O. WALKER, of Indianapolis, county ofMarion, and State of Indiana, have invented certain new and useful Improvements in Sash-Fasteners; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to theaccompanying drawings, in which like figures refer to like parts.

My invention relates to improvements in the construction of sash-fasteners; and its ob- Ject is to secure thorough and safe ventilation of the room either from above or below, or from both points at once, by the joint movement of both the upper and lower sashes when locked together, to prevent any lateral movement of the sash in the casing, and to operate the locking mechanism by a removable key, and will be understood from the following description.

In the drawings, Figure 1 is a perspective View of parts of the upper and lower sashes of the window and easing, the glass being broken away and showing my devicein place. Fig. 2 is an enlarged vertical section of the same on the line a: as, Fig. 1. Fig. 3 is a detail perspective view of the lock and key, the latter removed. Fig.4 is a central longitudinal section of the lock,the key beingin place and the bolt held back.

In detail, 1 is the casing, and 2 the upperand 3 the lower sash of the window.

4 is a metal plate provided with a central groove 5 and tapering sockets 6, this plate being let into the side rail of the upper sash and secured by screws, as shown in Figs. 1 and 2, the face of the plate being flush with the surface of the sash-rail.

7 is a lock composed of a casing having a spring-bolt 8, its end tapering and normally protruding from the opening in the end of the lock-casing, as shown in Fig. 3.

9 is a removable keyhaving a flange 10 and a pin 11, the pin moving in the slot 12, having the enlargement 13 in the top of the lockcasing. This lock is let into the meeting-rail of the lower sash, so that its top surface is flush with that of the rail, as shown in Fig. 1, its bolt-opening being in line with the central groove 5 in the plate 4, so that the tapering head will engage with the tapering sockets of such plate at the point desired. These sockets may be made any convenient distance apart that it is desired to set the sash. The flange 10 of the key will easily turn in the enlargement 13 of the slot in the lock-casing, and when desired the bolt maybe drawn back and the key turned and the parts locked in position, as shown in Fig. 4, and in such case it is obvious that the lower sash maybe raised or the upper sash be lowered without meeting with any obstruction. from the contact of the end of the bolt with the other parts of the sash, and there will be no scratching or abrasion of the wood or metal.

In Fig. 2 the upper and lower sashes are seen locked together, the'bolt being entered in the second sooketin the plate, whereby the upper sash is dropped to a distance equal to that between the two lower sockets, thus allowing ventilation over the top of the upper sash while the lower sash is in its normal position. WVhen the sashes are thus locked,

it is obvious that they are movable together, 1

so that if it is desired the sashes maybe raised together, closing the upper sash and lifting the lower sash a corresponding distance, thus ventilating the room from below, and if the key be removed it is further obvious that the sash may be left in this position over night, securing ventilation of the room without making an opening large enough to admit an intruder or enable him to unlock the sash without breaking the glass and providing himself with another key or its equivalent.

The bolt-head and sockets are made tapering, so that as the bolt slides forward, the diameter of its head being less than that of the socket-opening it will readily center itself and enter the socket without being hindered by any lateral movement or displacement of the sash, and to provide further against such displacement or lateral movement, so common in ordinary window-sashes, is the office of the groove 5, so that the head of the bolt will travel in this groove as a guide and will bear against the sides of the groove, and no lateral movement of the sash will therefore take place.

lock for a sash and a device to prevent rattling of the same, either from the vertical or the lateral movement in the casing, and also I thus combine in one device a provide for the safe and perfect ventilation of the room, either from above or below the sashes, or from both at the same time, for the sashes may be locked at such a point as to leave an opening above the upper and below the lower sash at one and the same time, and this secures the most thorough ventilation, as the hot airfrom the room can pass out in one current above while the cool air is coming in from below.

hat I claim as my invention, and desire to secure by Letters Patent, is the following:

1. A sash-fastener comprising a casing 7, having a tapering bolt 8 seated therein, a spring coiled around such bolt, forcing the same outward by its tension, a removable key 9, having a flange 10, an opening in the upper part of the casing to allow the insertion and operation of such key, such opening having an enlargement, whereby when the key is turned and engages in such opening the bolt is retained within its casing, substantially as shown and described.

2. A saslrfastener comprising a lock having a tapered bolt seated therein, a removable key, an opening in the upper part of the lock to allow the insertion of the key, such opening having an enlargement at one end for engaging with a flange formed on such key, whereby the bolt is retained within the casing, such lock fitting into the top of the meeting-rail of the lower sash, in combination with a metal plate let into the side rail of the nppersash and provided with a central groove and aseries of tapering sockets, substantially as shown and described.

In witness whereof I have hereunto set my hand this 26th day of December, 1891.
