WINDOW TIGHTENER Filed April 26, 1935 ATTORNEY.

Patented Jan. 28, 1936 UNITED STATES PATENT OFFICE 1 Claim.

One object of this invention is the provision of a device, simple in construction and operation, adapted to be attached to a window and operable to prevent the window from rattling.

Another object is to provide such a device which is adapted to be wedged between the window frame and sash so as to force the same apart, the device being at the same time yieldably locked in the wedging position.

The above and other objects will become apparent in the description below, in which characters of reference refer to like-named parts in the accompanying drawing.

Referring briefly to the drawing, Figure 1 is a fragmentary view of a. window illustrating the application of the device.

Figure 2 is a cross-sectional view taken on the line 2-2 of Figure 1.

Figure 3 is a view similar to Figure 2 with the device shown in wedging position.

Figure 4 is an underside plan view of the device per se.

Figure 5 is a view similar to Figure 1 illustrating the application of a modified form of the device.

Figure 6 is a cross-sectional view taken on the line 66 of Figure 5.

Referring in detail to the drawing, the numeral I represents a window sash and the numeral l l the window frame. The wedging device I2 is pivotally mounted by means of a screw l3 adjacent the frame H on the sash Ill. The member l2 comprises at one end a curved arm 14 having a handle [5, the arm l4 being of relatively fiat, resilient material. At its other end the member I2 is widened and rounded to provide a wedge Hi. It is apparent that when the member I2 is rotated from the position shown in full lines in Figure l to the position shown in dotted lines, the wedge IE will be forced between the sash l0 and the frame I l, as illustrated in Figure 3, thus preventing rattling of the window. To further prevent slipping out of locking position of the member I2, a sector I! having serrations l8 along its surface is mounted on the sash l0 under the member l2, and the underside of the latter is provided with a complementary sector IQ of serrations. The resiliency of the arm l4 urges the mutual interlocking engagement of the two sectors, thus securely locking the member I2 in 10 wedging position.

In the modified form of the device, a member 20 is provided with a slot 2| by means of which the member 20 is secured slidably on the sash I0. At one end the member 20 is provided with a handle 22 and at the other with a wedge 23. To lock the window against rattling, the member is simply slid toward the frame ll, causing the wedge 23 to force the sash and frame apart.

Obviously, modifications in form or structure 20 may be made without departing from the spirit of the invention.

I claim:

A device of the class described comprising a member pivotally mounted on a window sash, said 25 member comprising on one end a resilient arm having a handle and on the other end a rounded wedge, said wedge being forced between the window sash and frame upon rotation of said member in one direction, and means for releasably locking said member in said wedging position comprising an arcuate member rigidly mounted on said sash concentrically with the pivot of said pivotal mounting under said first-named member and provided with serrations, and serrations 3 on the underside of said first-named member yieldably registering in said serrated member.
