simple, eflicient, durable, inexpensive and which may be readily and inexpensively installed.

The same also has as an object the production of a device of the kind described which may be installed without additional fastening means or with use of tools which may be made in a variety of sizes to fit different constructions, but which does not require exact size where there is slight variation in the dimensions of window frames of different windows or in the same window.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given. I

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawing, wherein like reference characters indicate like or corresponding parts:

Fig. 1 is a perspective view of a portion of the window frame and sash frame with the weather strip applied;

Fig. 2 is a perspective view of a portion of a window frame showing application of the strip to the side of the frame; and

Fig. 3 is a perspective view of a portion of a strip before application to the frame.

Referring to the drawing, in which only one embodiment of the invention is shown, it may be mentioned that the window frame and sash frame illustrated in the drawing are typical of the usual construction, the frame being, of course, car ried by the building structure and the sash being hinged to the window frame so as to swing in the desired direction.

The weather strip is preferably made from sheet spring metal, such as spring bronze metal or the equivalent, which has resiliency and which will not corrode. The sheet of metal, which may be comparatively thin, is in the form of a strip of the desired width and length which is rolled, folded or bent to provide the strip proper and integrally formed means for securing the strip in place. In the strip illustrated the strip is formed with a portion I having one edge rolled over as indicated at 2 and thence bent as at 3 to provide a cooperating strip 4. The strip portions l and 4, as will be noted, are connected by a rolled over or intermediate portion without a sharp reverse bend so that the intermediate portion in a way constitutes a resilient hinge, the whole more or less resembling a V-shaped structure with the point of the V enlarged. The strip is secured in place by mounting the same upon the stop on the window frame so that the strip portions I and 4 are interposed between the stop and the window sash. Y

As shown, the free edge of the strip portion 4 is folded back upon itself at 5 and extends as at 6 in proximity to the portion 4. The same is then bent laterally away from 4 as indicated at l to provide a portion 8 which extends substantially at a right angle to the part 6 and is adapted to seat upon the face of the stop frame. The ex- .treme edge of the metal sheet is bent over as at 9 so as to provide the side portion III which is arranged to cooperate with portion 6 to form a stop clamp, whereby the weather strip is secured to the window stop andmaintained in place without other fastening means. It will be seen by referring to Fig. 3 that the bend at 9 is suflicient to bring the extreme free edge of the portion 10 toward the portion 6 so that when the device is fitted to a window stop part i0 is'under tension. It is generally preferred to form a bead or slight bend H at the juncture of the strip I and the intermediate portion 2 and to slightly turn over the edge I! so as to provide a rolled edge where the strip first comes in contact with the window sash.

Referring to Fig. 1, l5 represents the metal window frame which is provided with a window stop i6 and may be flanged as indicated at ll. The window frame also has the side frames formed as indicated at l8, l9 and 20. A typical sash frame is shown in Fig. 1 made up of the angle 23, 24 and 25 which is hingedor operatively secured to the window frame in any suitable or desired manner, usually hinged at one side of the window frame and provided with means at the opposite side for locking the same in closed position.

The weather strip is applied to the frame of the window by seating the same on the flanges or stops it at the top and bottom and H at the sides. It is easily positioned by seating the member ID and positioning the device over the stop with the side or end portion of the channel 8 seated upon the face of the stop with the stop tightly clamped 29 on, the portion ID of the channel which will between the sides 6 and I0. When so arranged the engage directly with the frame, either at the lower tension or resiliency of the metal is sumcient to edge of the flange IE or in a groove 30 (see Fig. l) secure the strip in operative position and mainwhich may be formed in the frame.
