- FASTENER FOR THE MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 440,800, dated November 18, 1890.

Application filed May 16, 1890- Serial No. 352,063- (No model.)

To (LZZ whmn it may concern.-

Be it known that I, JOSEPH 00D, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Sash-Fasteners, of which the following is a specification.

My invention relates to improved fastening means of the general class employed for securing togetner the upper and lower sashes of windows at their meeting-rails to prevent opening of the window from the outside.

My object is to provide a fastener of the above class of improved construction, which shall operate to automatically secure the window whenever it is closed; and it is also my object to provide such a fastener which may, furthermore, be operated when desired to draw the meeting-rails together and thus secure the sashes against rattling.

In the drawings, Figure 1 is a broken sectional View showing the meeling-rails of the upper and lower sashes of a window provided with my improved fastener, which is in the condition of being locked to secure the window against being opened from the outside and against rattling; Fig. 2, a similar view showing, however, the position of the fastener, which it assumes automatically when the window is closed to prevent the window from being opened from the outside; and Figs. 3, 4, and 5, enlarged detail perspective views of the parts of the fastener detached.

The fastener is in two parts A and B. The part A comprises a base plate 1, through which it may be fastened by means of a screw upon the meeting-railw of the lower sash, and the plate is provided with a forked extension 5, projecting upward and slightly backward. Between the forks of the extension 8 are steps 8 the upper one of which 5' forms an inclined plane, as shown. From the lower step 8 the plate t projects forward, and in securing the partA upon the meeting-rail wthe forward edge of the plate should project beyond the edge of that rail and overlap the adjacent edge of the meetin grail y of the upper sash.

' The part 13 comprises a plate 0', at which it may be fastened upon the meeting-rail of the upper sash, and the plate is provided with two upwardly-projecting parallel standards g, between which is mounted a latch B. The latch is pivoted toward its center upon a pin g, which passes through the latch andinto bearings in the standards, and is thus in the na ture of a double-winged latch, one wing 19 having a tapering and slightly-rounded end port-ion and the other wing 0 a head n and extension 172, provided with a recess m in its end, all as shown. The head a is wider than the rest of the latch, and is provided on its inner side with cam-faces n. The parts 2) and 0 of the latch all, except the head portion, will swing freely between the standards (1 and between the forks of the part A.

The parts being secured upon the meetingrails, as described, and as shown in Figs. 1 and 2, when the side 0 of the latch is swung forward, owing to the natural tendency to slight separation of the meeting-rails, the cam-faces strike at about ,2 upon the tops of the forks s and rest lightly in that position. This will not prevent the window from being opened; but a downward pressure exerted upon the head causes its cam-faces a to slide down the outer surfaces of the forks s and the recessed end m to embrace the step 3 which operation draws the meeting-rails together and fastens the Window securely against being opened from the outside. hen it is desired to open the window, the latch is raised to disengage its cam-faces from the forks, and is permitted to rest lightly on the ends of the forks, as first described. Raising the lower or lowering the upper sash will turn the latch over until the headed side, which is the heavier, drops down to the position shown in Fig. 2, the side 1) being thus caused to swing under the meeting-rail a; of the lower sash. As the window is closed again, the meeting-rail or will wipe against the part 1) of the latch, and when the rail is passed the part 19 will be swung forward between the forks s and engage the surface of the step 5 which will prevent the window from being opened, as the head a cannot pass between the standards q.

Should dust, snow, or other substance accumulate on the window-sill while the lower sash is raised and interfere with the complete closing of that sash, the wing p of the latch by engaging the step 3, or even the surface of the plate t, will still operate to prevent the sash from being raised. When it is desired to secure the sashes against rattling and pre- Vent the passage of drafts between the meeting-rails, the latch is turned from the position shown in Fig. 2 and pressed down, as described, to that shown in Fig. 1.

If desired, the part A may be formed of metal which will permit a limited degree of spring to the forked extension 3, and this will facilitate locking in the manner shown in Fig. 1, where the meeting-rails 0f the windows do not tend normally to separate, as described The plate 15, overlapping the edge of the rail of the upper sash, will prevent the latch from being unfastened from the outside by the insertion of an instrument between the meeting-rails.

What I claim as new, and desire to secure by Letters Patent, is

1. In a window-sash fastener, the combination of a catch to be fastened upon the meeting-rail of the lower sash, and a latch B, pivotally supported between its extremities on a bearing to be fastened to the meetingrail of the upper sash and having alighter end to engage normally with the said catch when the Window is closed, and a heavier locking end to be turned into engagement with the catch, thereby disengaging from it the lighter end and interlock with the said catch, substantially as described.

2. In a sash-fastener, the combination, with a part A, secured upon the meeting-rail of the lower sash, comprising a base-plate t, providedwith an upwardly-projecting and back- Wardly-inclined forked extension 3, and a step 8 between them, and a part B, secured upon the meeting-rail of the upper sash, compris ing a base-plate r, a standard g on the baseplate, and a latch B, pivotally mounted toward the center on the s andard to swing in a vertical plane and provided with a wing 19, and a heavier wing 0, having a recessed extension m and laterally-extending cam-faces a, substantially as and for the purpose set forth.
