WEATHER-STRIP.

Specification of Letters Patent.

Patented' Apr. 27, 1920.

Application filed March 16, 1917. Seria1 No. 155,298.

To all ful/tom t may concern:

Be it known that I, CHAnLEs H. STARK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Weather-Strips, of which the following is a specification.

The weather strip which is the subject matter of the present application for patent is designed more particularly for sealing the joint between a window and door frame and the masonry wall in which the frame is fitted.

The invention has for its object to provide a weather-strip of the kind stated which can be readily applied without altering or modifying the structure to which it is applied, and which forms an effective seal.

The object stated is attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed and in order that the same may be better understood, reference is had to the accompanying drawing forming a part of this specification.

In the drawing- Figure 1 is a perspective view of a fragment of the packing strip, and

Fig. 2 is a horizontal section showing the strip in place.

Referring specifically to the drawing, the invention is shown applied to the joint between a window or door casing and the masonry wall in which said casing is fitted, but it will be understood, that the invention is not limited to this particular application, but may with equal facility, be applied to other locations. The masonry wall is shown at 5, and the stile of the window casing at 6, the latter having the usual staff-bead 7 on the outside which seats at its inner edges against the wall. rlhe weather strip which is the subject matter of the present application is applied to the joint between the abutting parts 6 and 7, and also where the wall abuts against the window casing.

In carrying out the invention there is provided a sheet metal base strip 8 of suitable length according to the length of the joint, said strip being constructed to serve as a holder for two packing strips 9 and 10 of felt or other suitable material usually employed for weather strips. The strip 8 is bent lengthwise to form an outstanding flange 11 extending throughout the entire length of the strip, and the latter is therefore angular in cross section.

forming the wall.

The packing strip 9 is positioned on that side of the base strip 8 from which the flange 11 projects and the packing strip 10 is carried by the flange. The packing strip 9 is secured at one edge by crimping or bending the marginal portion of the strip 8 over as shown at 12 to tightly grip the same, and the packing strip 10 is secured to the flange 11 by rearward and return bends 13 at the outer edge thereof, said strip being gripped between said bends. Thus, the two packing strips are offset with respect to each other and the strip 10 is in advance of the strip 9.

In applying the device, the strip 8 is placed. against the outside face of the plank forming the stile 6 of the window casing so that the flange 11 seats on the inner edge of the bead 7 projecting laterally from the stile. This is done before the wall 5 is run up. The packing strips 9 and 10 face outward, and hence when the bricks or other building blocks forming the wall are laid7 the pack ing strips seal the joint between the same and the parts 6 and 7 as shown in Fig. 2. The bent portion 18 of the base strip is embedded in the mortar or other binding material between the inner and outer bricks The joint is therefore provided with a double packing, resulting in the same being most effectively sealed against the passage of wind, dust and moisture, and as both pads are mounted on a single base, the device can be easily applied, without makingy any changes or modifications in the wall or window casing.

The sheet metal base strip serves to hold the packing strips in proper position while thedbricks or other building blocks are being lai I claim: j

A weather strip comprising a flat rigid base strip having a bend in vthe direction of its length to form a lateral outstanding flange extending throughout the entire length of the strip, a packing strip attached to the longitudinal edge of the base strip and covering the face thereof from which the flange projects, and a packing strip attached to the extremity of the aforesaid flange, said last-mentioned packing strip being offset relative to the first-mentioned packing strip and located in advance thereof.

In testimony whereof I aliix my signature.

CHARLES H. STARK.
