710 for use wherever found applicable. More es pecially it has as an object the production of an eflicient weather stripping or sealing strip between two relatively sliding parts such as, for example, a sliding sash, same being arranged between the edge of the sash and sash frame or window jamb. It has among its other objects the production of a stripping of the kind described which will not only effectively form a seal between the sliding parts,

thereby shutting out cold winds, rain, dust and dirt, but which will tend to prevent chattering of the window sash, as well as tend to cause the same to run true in the window frame. The same may be installed either in 2. new work or in old constructions without requiring the removal of the sash or sliding part, and when once installed fits itself to the particular installation. Many other ob ects and advantages of the method and construc- -?'0 tion herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

' 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 drawings, wherein like reference characters indicate like or corresponding parts:

V Fig. 1 is a sectional view through a portion of a window sash frame or window jamb, with my improved weather stripping applied thereto; and

Fig. 2 is a perspective View of'a strip of the weather stripping enlarged to more particularly show the construction and form before installation. 7 r p Referring tojthe drawings, in which a preferred embodiment is shown,,the weather stripping consists of a strip of metal, preferably spring metal, that will not corrode and of suitable gauge to have the desired degree of resiliency. In the strip shown, the same is formed with what may be termed a tacking flange or edge 1. Then it is bent away from the plane of the flange 1 as indicated at 2, and thence bent over again as indicated at 3,

and thencemore or less parallel with the flange 1 as indicated at 4-6, thence bent over again as indicated at 7, and back as indicated at 8, and thence more or less parallel inthe same plane as the flange 1 to provide an edge flange 9 at the opposite side of the strip. The bends at 3 and 7 form substantially beads and are preferably more or less rounded as shown so as to project beyond the portion 4.--6 between the two side flanges. At a desired point intermediate the beads 3 and 7 there is provided a bead 5 which I prefer to form with a substantially sharp bend or angle at the outer face portionand which is of a height to project beyond or above the rounded beads 3 and 7 While the heads 3 and 7 may themselves be sharper than shown, these are generally made rounded, the degree of the rounding depending upon the size of the strip, the

gauge of the metal, etc.

At the juncture of the flange 1 and portion 2 and flange 9 and portion 8, it is generally preferred to slightly round the strip as indicated at 10 and 11. As shown in Fig. 2, the outer edges of the flanges 1 and 9 are bent slightly laterally. It has been found in applying weather stripping of this character that there is a tendency for the edges of the flanges, particularly the edge of the secured flange, to turn upward. This tendency to turn upward is due to some extent to the presas shown in Fig. 2, this difficulty is overcome H and a perfect seal obtained. The weather stripping "when appliedv assumes the form shown in Fig. 1. i

In Fig. 1 1 have illustrated a window frame or jamb 15 and a window sash 16, 17, I

being the usual stops. In the space between herein shown the edge of the sash and the frame is positioned the weather strip, the same being suitably secured to one of the parts, for example, as shown to the jamb by means of tacks 18 or equivalent means for the purpose.

When the weather strip is first applied, it y endto mor .Q le fiattenou the P n ed beadfi will be in engagement with. the sash 16. Depending upon the thickness of the metal in the strip, the beads 3 and 5 may or may not be in contact -with the sash or one or the other may not. If the gauge of the metal is such that the portions 4 and 6 are depressed, all three may .be in contact. This, however, is more or'less immaterial. After the strip has been in use for a short Feriodottimmthe bead 5*tends to wea o i. thelbeads 3 and .7 are in contact with the Sash edge with the bead 5 inits formedv groove 19. .iQbviously, a perfectseal is secured, pre venting the passage of wind, rain, dust or dirt or foreign material between the sash and .its frame. The engagement with the sash in .the mannerdescribed tends to prevent chatteringor vibration of the sash, the weather stripping yieldingly holding the sash against undue vibration. The sash runs easy on the strip.

It will be particularly notedthat this type of weather stripping maybe installed in old work without removing the .sash from the frame, .and should it be required may be removed or renewed in the same manner. It isunnecessaryto remove the sash forrgroove 19 to .be formed,same being formed by bead 5 after the installation. On new .work, a slight groove or saw-,kerfmay be formed in thesash in which the groove forming angle islocated, servin as a guide for the sameand aiding in the ormation of the complete ,groove by use. The sash is always .maintained in proper position between the stops and as aresult .will always run true.

I-Iavingthus described my invention, it is obvious-that .various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to theexact form, construction, arrangement and combination of parts and .described or .uses mentioned.
