To all whom it may concern:

Be it known that we, CHARLES A. BLoH'M and CLARENCE H. OHAMBERLIN, citizens of the United States, residin at Milwaukee, county of Milwaukee, and gtate of VVisconsin, have invented new and useful Improvements in YVeather-Strips, of which the following is a specification.

Our invention relates to improvements in weather strips for windows, and pertains esgrooved window sash is provided with one or more metallic members adapted to interact with and slidingl-y engage counterpart members on the window frame or casing.

The object of this invention is to overcome the dificulty heretofore experienced insecuring such strips to the window sash and they will not catch or bind upon each other, nor upon the securing devices, the latter serving, in our improved construction, to reduce the friction of the window sash when moved alon the window frame.

In the fo lowing description, reference is had to the accompanying drawings, in which, i

Figure 1 is a frontwiew of the lower portion of a window frame and-sash with our invention applied thereto. Fig. 2 is a detail of Fig. 1. Fig. 3 is an edge view of a portionof one of the side rails of asash.

Like parts are identified by the same reference characters throughout the several views.

The casing 1 of the window, at the sides and along the sill 2 is provided with a metallic member, which, in the construction illustrated,-in Fig. 2, comprises a strip-of comparatively thinmet-al folded along longitudinal lines to form a set of ribs 3 and'& and laterally projecting base members 5 and 6, which extend in the same direction from the ribs and are lapped upon each other sub- Securing screws or tending margins of the strip into the window casing, the heads ofthese screws being preferably countersunk in the outer member 6 and having fiat outer surfaces.

Each window sash is provided with a 9 respectively, and this groove is lined with p I specification of Letters Patent. Patented $31M]. 21,1,9QQ. Application filed February 15, 1999. Serial No. 477,858.

a metallic member comprising a strip of metal bent or folded along longitudinal lines to form walls 10 and 11 for the sides of the groove and a base wall 12 having'an outwardly projecting rib 13 which subdivides the groove into two channels adapted to loosely receive the ribs 3 and 4 respectively. One margin of this strip constitutes the outer edge of the side wall 11. The strip along the outer margin 14 is extended laterally to the edge of the-sash and secured to the sash at the ends of the groove, preferably by round headed nails or screws 15, the

heads of which form bearings adapted to travel along the outer surface of the member 6. This construction not only avoids the necessity of applying nails or screws in the narrow spaces between the ribs, but the laterally projectin members-form smooth metallic opposing caring surfaces which will not permit the sash to bind especially where the round headed screws or nails are em: ployed to serve as spacin and antifriction devices. It is not materia to our. invention whether the lateral extensions are out-ward or inward extensions, that is, whether they project toward the exterior or interior of the building.

- In Fig. 3 it will be observed that where a sash cord groove 17 is employed, the packing strip groove connects with it along one side the two grooves, constituting a single wide groove of sufficient width to receivle the packing strip and the sash cord 18.

Having thus 7 described our invention,

what we claim as new and desire to secure by Letters Patent is,' I.

1. The combination with a window casing, and a sashhaving a groove in its side and bottom margins, of a strip of metal folded longitudinally .to form overlapping portions in the plane of the window casing and secured thereto, said strip having its folded margin bent outwardly to form a projecting rib .en aging in the sash ,groove, and said strip aving one of its sides additonally folded outwardly to form a second rib substantially parallel to,the first mentioned rib, and between it and the overlapped edge margins, together with another strip of metalforming a lining forthe sash groove and folded to providerib receiving channels, substantially as described.

2. The combination with a window casing and a sash having a groove in its side and bottom margins, of a folded strip of metal having its edge margins substantially coincident with each other and'having two outwardly extending. folds forming ribs, one of which is located at the side of the strip opposite the ed e margin and the other of which is paralle thereto and occupies an intermediate position between the first mentioned strip and said edge margins, flat headed screws countersunk in the overlapping'portions of said strip and securing said portions of the strip to the window casing between the ribs and the edge margins, together with another strip ofmetal forming a lining or-the sash groove and folded to provide rib receiving channels, said strip havin a sin 1e laterally extendin flange on the si e of 516 groove opposing the secured margins of the strip connected with the casing, said flaii'e being secured to the sash by round head screws projecting from the surface of the flange and forming bearin CHARLES A.
