SPECIFICATION forming part of Letters Patent No. 453,177, dated June 2, 1891.

Application filed February 6, 1891. Serial No. 380,467. (No model.)

Massachusetts, have invented certain new and useful Improvements in VVindow-Fasteners, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to window-fasteners for securing together the upper and lower sashes of windows having vertically-movable sashes; and it consists in certain novel features of construction, arrangement, and combination of parts, which will be readily understood by reference to the description of the drawings and to the claims hereinafter given, and in which my invention is clearlypointed out.

Figure 1 of the drawings is an elevation of a window with myimproved fastener applied thereto, the same being shown with the sashes closed and locked and viewed from the interior of the room. Fig. 2 is a vertical section on line w 90 on Fig. 1, looking toward the right of said figure, and showing both sashes moved from their normal or closed positions and locked together. Fig. 3 is a plan of that portion of the fastening which is secured to and moves with the lower or inner sash. Fig, at is an inverted plan of the same, partly in section. Fig. 5 is a central ,vertical section of the base of the same, and showing the fasteniug-lever and the spring in elevation; and Fig. 6 is a plan of the locking-latch detached.

In the drawings, A is the lower sash, B the upper sash, O O portions of the windowframe, D the window-sill, a a a the stopbeads, and b the parting-bead, all of which are of ordinary construction. n

To the upper or meeting rail 0 of the lower sash is secured the base-plate cl of the fastener, made in the form of a shallow inverted cup and having pivoted to its center the fastening-lever E, provided at its front end with the fin ger-pad e and the downwardly-projecting lug c, and having formed in the side of its rearwardly-projectin g arm the open slot e which engages the post F between two of the collars f, formed thereon, to fasten the two sashes together, either in a closed position or in a partially-opened position, as shown in Fig. 2.

The post or column F has formed thereon the base-flange f, by which and the screws f it is firmly secured to the lower or meeting rail of the upper sash B in an upright position, and has formed thereon a series of circumferential grooves g, each of a vertical width equal to or slightly greater than the vertical depth of rear or hook end of the lever E, said grooves g and the collars f being so arranged on said post or column that the lower groove shall be in position to receive the slotted end of the lever E when the two sashes are tightly closed, as shown in Fig. 1.

The base-plate (Z has formed in its cylind rical wall two rectangular slots d and d and in its upper surface the slot (i curved concentric to the axis of the pivot about which the lever E moves in fastening and unfasteniug the window.

The lever E has set in its under side the pin h. which projects through the slot (1 into the chamber of the base-plate d, as shown in Figs. 4 and 5.

II is the locking latch-lever provided with the operating-arm h. and with the shoulders i and i, one at each end of the curved wedgelike expansion 7L which projects through the slot 61, while the arm h projects through the slot d as shown in Figs. 1, 2, 3, and 4. The shoulder 11 of the latch-lever H rests against the right-hand end of the slot d',with the toe 1? bearing against the inner surface of the wall of the chamber, against which it is pressed by the tension of the scroll-spring j, the outer end of which is connected. to the locking-lever H by having a portion thereof bent at right angles to its main body and inserted in the hole 1 formed in said lever near the shoulder t',while the inner end of said spring is attached to the end of the pin h, as shown in Fig. 4:. By this construction and arrangement of the fastening-lever E, the locking-latch H, and the spring j a single spring is made to serve the purpose of holding the fastening-lever E in either its engaged or disengaged position, and also to press the locking-latch H outward, as shown. This is accomplished by virtue of the fact that the inner end of the scroll-spring is attached to the pin h, which,when the lever E is moved from one extreme of its movement to the other, travels in a curved path concentric to the axis of motion of said lever and from a point on one side of a radial line Z drawn through said axis and point of attachment of the outer end of said spring to the latch-lever II to a point upon the opposite side of and about the same distance from said line. \Vhen the lever E is moved in either direction, the spring j tends to resist such movement until the pin 7i reaches a point on the line Z Z; but when said pin has passed said line the tension of the spring tends to move said pin toward the end of the slot (1 the ends of which serve as stops to limit the movement of the lever E in either direction.

By the use of my improved fastening the window-sash may be securely locked together either in a closed position or when partially opened for the purpose of ventilation, and may be so adjusted as to be open at the bottom or top, or both top and bottom, and still be secure against attacks of outsiders, except by breaking the glass.

In some cases, where it is only desired to fasten the window in a closed position, the post F would be made only of sufficient height to have formed thereon the lower groove g, all of said post above the lower collar f being omitted.

I claim- 1. The combination, in a window-fastener, of a post or column to be secured to the meeting-rail of the upper sash and provided with a circumferential groove, a base-plate to be secured to the meeting-rail of the lower sash, a two-armed lever pivoted to said base-plate so as to be movable about said pivot in a horizontal plane, and provided on its front arm with a pendent lug and having its rear arm constructed and arranged to engage the groove in said post, stops to limit the movement of said lever in both directions, a latch-lever for locking said two-armed lever in engaged position, and a spring for controlling the action of said latch-lever.

2. The combination, in a window-fastener, of a post or column to be secured to the meeting-rail of the upper sash and provided with a series of circumferential grooves formed thereon one above the other, a base-plate to be secured to the meeting-rail of the lower sash, a two-armed lever mounted upon said base by a vertical pivot and provided on its front arm witlra pendent lug and having its rear arm constructed and arranged to engage either of the grooves on said post or column, and a spring-pressed latch for locking said lever when in engaged position.

3. The combination of a pivoted lever constructed and arranged to be vibrated about its pivotal connection, stops to limit the move-- ment of said lever in both directions, and a scroll-spring having its outer end pivoted in a bearing intermediate between the two extremes of the angular movement of said lever and its inner end connected to said lever, so that said spring shall tend to press said lever against its stop at either extreme of its movement.

4. The combination of the inverted-cu p-like base-plate (Z, provided with the slots (1, d and d, the lever E, pivoted to said base-plate and provided at one end with the slot 6 and at its other end with the lug e, the locking latch-lever H, the pin h, set in the lever E and projecting through the slot (Z the scroll-spring j, connected at one end to the latch-lever II and at its other end to the pin it, and the post or column F, constructed and adapted to be secured to the meeting-rail of the upper sash and provided with a series of grooves or notches to receive the inner end of the lever l, substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of twosubscribing witnesses, on this 5th day of February, A. D. 1891.
