n I Q o A 7 UNITED STATES PATENT oFFIoE.

CHARLES V. WALKER, OF BOZEMAN, MONTANA.

SASH-FASTE NEIR Application filed October 7, 1907.

To all whom it may concern:

Be it known that I, CHARLES V. WALKER, a citizen of the United States, residing at Bozeman, in the county of Gallatin and State of Montana, have invented certain new and useful Improvements in Sash-Fasteners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 7

This invention relates to improvements in saslrfasteners.

The object of the invention is to provide a sash-fastener by means of which a window sash. may be supported and automatically locked in any desired position.

A further object is to provide a device of this character which will be simple, strong, durable and inexpensive in construction, efflcient and reliable in operation and well adapted to the purpose for which it is de- Signed.

With these objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a vertical sectional view through one side of a window sash and frame, showing the application of the invention thereto to support and lock the sash in a raised position Fig. 2 is a similar view showing the position of the fastener to lock the window in a closed position; Fig. 3 is a horizontal sectional view through 'one side of the sash, and a portion of the window frame; Fig. 4 is an inner edge view of one side of the sash; and Fig. 5 is an outer edge view of the same.

Referring more particularly to the drawings, 1 denotes the sash, and 2 denotes the side of the window frame in which the sash is mounted. In one of the side rails, 3, of the sash, adjacent to its outer edge, is formed a recess, 4, the inner wall of which is inclined inwardly from its upper and lower ends, thus providing bearing surfaces, the object of which will hereinafter appear. In the side rail, 3, of the sash, adjacent to the upper end of the recess, 4, is formed an obliquely disposed passage, 5, which extends from the inner edge of the rail through the same and communicates at its inner end with the upper portion of the recess, 4, as shown. In the Specification of Letters Patent.

Serial No. 396,292.

passage, 5, at the outer end of the Same, is arranged a wearing sleeve, 6.

In the recess, 4, is arranged a locking or fastening device, which is here shown and is preferably in the form of a circular disk or cylindrical metal block, 7, in one side of which is formed a slot, or recess, 8, through which extends the end of a flexible operating element, 9, the inner end of which is suitably secured to the opposite side of and eccentric ally to the disk, 7, thereby permitting said disk to roll to a limited extent on the bearing surfaces formed by the inclined inner wall of the recess, 4, when said disk is drawn up or let down by the flexible connection, 9. The flexible connection 9 is here shown and is preferably in the form of a chain and extends through the passage, 5, and is provided on its outer end with a ball, or bead, 10, which prevents said end of the chain from passing into the outer end of the passage, and also rovides a suitable grip by means of which the chain may be readily grasped to operate the disk, 7.

In operation, when it is desired to raise the window, the chain 9 is pulled outwardly, thus raising the disk, 7, to the center or widest part of the recess, 4, in which position the disk is entirely within the recess and does not engage the adjacent edge of the window frame. After the window has been raised to the desired extent, a further pull is applied to the chain 9, which will draw the locking disk upwardly into engagement with the upper inclined wall of the recess, 4, wherein the same will be tightly wedged between said wall and the adjacent side of the window frame, thus providing a chock, or wedge, which will tightly hold the window frame 1n an'elevated osition. When it is desired to lower the wmdow sash, the same is lifted to a sufficient extent to disengage or loosen the disk, 7, from between the inclined upper wall of the recess and the adjacent siole of the window frame, after which said block may be lowered by the chain 9 of the central portion of the recess and out of engagement with the adjacent side of the win dow frame, thus permitting the sash to be readily lowered. The sash is locked in its lowered position by allowing the disk 7 to drop down into engagement with the .lower inclined wall of the recess, 4, wherein the same will become wedged between said wall and the adjacent side of the window frame,

which will prevent the raising of the window until the disk or block is again pulled up by means of the chain, 9, as hereinbefore described.

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

In combination with a window frame and a sash apertured in the edge to form a twin pair of oppositely inclined wedging walls, said sash having an edgewise channel connecting with the aperture therein, of a wedging device adapted to operate over said inclined Walls, said wedging device comprising a pair of spaced disks, an integral bridgepiece connecting said disks at their lower ends, a chain having its end link secured to the bridge-piece to pass through said channel, and a handle on the chain at the opposite end to the disks.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

CHARLES V. WALKER.
