SASH-FASTENER.

Specification of Letters Patent.

Patented March 5, 1907.

Application filed September 26, 1906. Serial No. 336,284.

To all whom, it may concern:

Be it known that I, EMANUEL SLOAN, a

citizen of the United States of America, residing at Beehouse, in the county of Coryell and btate of Texas, have invented new and useful improvements in Sash-l asteners, of which the following is a specification. This invention relates to improvements in sash-fasteners, comprehending particularly simple and convenient means for locking the lower sash of a window to the windowframe, the object of the invention being to provide an inexpensive type of fastener which may be readily adjusted to secure the sash at any desired elevation or to permit free movement of said sash throughout its range of adjustment.

1n the accompanying drawing, Figure 1 is an inner elevational viewof a window frame and sash equipped with my invention, the fastener being in release position to permit the sash to be raised and lowered. l ig.

- 2 is a similar view showing the fastener in looking position. Fig. 3 is a detail view of the latch-hook. Fig. 4 is a similar view of the keeper.

Referring to the drawings, 1 designates a window-frame of ordinary construction having arranged therein sashes 2 and 3, mounted .in the ordinary or any preferred manner.

The bottom rail of the lower sash 2 is provided with finger-pieces 4 to enable it to be conveniently raised and lowered, and secured at one end to the upper left-hand corner of said sash 1s a spring-metal supportingstrip 5, extending inwardly and upwardly in inclined relation above the upper rail of the sash. Secured intermediately to the inner'or free end of the said spring supporting-strip is a locking-bar 6, which extends across the frame and has its end portions arranged to be moved by a tilting action of said bar into and out of engagement with the inner faces of the jambs of the frame to lock the sash against movement or release it for adjustment. The bar is supported and held in a normally inclined operative position by the strip 5, in which posi tion the ends of the bar lie in contact with the jambs, thus holding the sash 3 from movement, the arrangement being such, however, that when the bar is tilted to a greater degree the ends thereof will move out of engagement with and free the sash.

The normally upper or right-hand end of the bar carries a latch-hook 7, pivoted thereto adjacent at its upper end, as indicated at 8, the upper end of the shank of the hook being provided with a flange 9, resting upon the upper surface of the bar, whereby the lateral swing of the hook is limited. The lower end of the latch-hook is provided with the hooked portion 10 and is arranged to slide in a keeper 11. This keeper 11 com prises a substantially rectangular plate pivotally n'lounted at one of its upper corner portions upon the adjacent side rail of the lower sash upon a screw or other suitable pivotal connection 12 and provided at its lower end with an upturned channeled guard or stop 13, normally arranged to lie below the book 10 to hold the latch member from downward movement with the said hook in locking engagement with the screw 12, thus holding the normally upper end of the lockingbar 6 depressed, so that the ends of said bar will be held in contact with the windowframe to hold the said sash from movement. The keeper is adapted to be swung inwardly onits pivot out of the path of downward movement of the hook 10, thus permitting the latch member to be elevated and the normally upper end of the bar 6 to be raised to throw said bar out of locking engagement with the window and allow free movement of the sash 2.

An operating-rod 14 is connected at its upper end to the normally lower end of the bar 6 and slides in a guide 15 on the rail opposite that on which the keeper is mounted,

the lower end of said rod being provided with a suitable finger-piece 16. By means of this red the bar may be tilted to throw it out of contact with the frame and to raise the latch 7 out of engagement with the pin 12 when the keeper 1 1 is swung laterally to the release position, (shown in l ig. 2,) thus permitting free movement of the sash, the bar being returned to locking position by the spring 5 when the rod is released. Hence it will be seen that a simple form of fastener is provided, whereby the sash may be locked at any desired position in its range of adjustment and released at any time for adjustment.

it will be understood that the bar 6 is adapted to tilt slightly on its fulcrum at its point of attachment tothe spring and to move up and down with the spring, which latter is preferably rigid enough to limit its range of movement to the extent sufficient to eil'ect the adjustment of the bar to locking and release positions, for which but a slight up-and-down and tilting movement is required. When the rod 14 is drawn downward, the pull of the same upon the normally lower end of the bar 6 will result in both the spring and bar being slightly depressed, while the bar will also be slightly tilted to incline it to a greater degree,

whereby its respective normally lower and upper ends will be moved downward and upward to the slight extent required to move the same out of contact with the ambs of the frame. When the rod 14 is released, the spring 5 will restore the parts to normal position, whereby the bar will again bethrown into locking action. The use of the latch device prevents any possibility of the bar being jarred out of locking position.

aving thus described the invention, what is claimed as new is I 1. In a sash-fastener, the combination with a window-frame and a sash slidabl mounted therein, of a normally inclined tilting bar pivotally mounted upon the meetingrail of the sash with its ends arranged to en gage the opposite sides of the l 'ame, a latch evice cooperating with one end of the bar for normally holding the bar in locking position, said device being releasable to permit movement of the bar, and a retracting device con nected with the other end of the bar for tilting the released bar to throw it out of looking position.

2. In a sash-fastener, the combination with a sash-frame and a sash slidably mounted therein, of a normally inclined spring-actuated tilting locking-bar pivotally mounted upon the meeting-rail of the sash with its ends arranged to engage the opposite sides of the window-frame, a swinging keeper upon the one of the side rails of the sash, a latchhook carried by the normally upper end of the bar to engage said keeper, whereby the bar is held in looking position, and a retracting 'device connected with the normally lower end of the bar and in guided engagement with the other side rail of the sash for tilting the same to retracted position when the keeper is swung out of engagement with the latch-hook.

3. In a sash-fastener, the combination with a window-frame, and a sash slidably mounted therein, 01 a tilting locking-bar arranged above the meeting-rail of the sash, said bar being coextensive in len th with said rail, a supporting-spring for the bar opera- 1 two to normally hold the same in looking position with its ends in engagement with the opposite sides of the window-ilrame, a latch member pivoted to one of the ends of the bar, a keeper upon one of the side rails of the sash adapted to be engaged by said latchmember to hold the bar in looking position, and an operating-rod in guided connection with the other side rail oi the sash and connected with the other end of the bar, whereby the latter may be tilted to throw it out of locking position.

In testimony whereof I affix my signature in presence of two witnesses.

EMANUEL SLOAN.
