WEATHER-STRIP.

Specification of Letters Patent.

Patented Feb. 18, 1919.

Application filed February 23, 1918. Serial No. 218,757.

To all whom it may concern:

Be it known that I, EMIL J. MEYER, a citizen of the United States,residing at Cape Girardeau, in the county of Cape Girardeau and State of Missouri, have invented'certam new and useful Improvements in Weather- Strips, of which the following is a specifica tion.

This invention has relation to weather strips for doors and windows, and has for an object to provide a weather strip including a resilient penetrative member to be mounted upon the door jamb or window casing and a receptive resilient element to be mounted on the door or window sash engageable by the penetrative member when the door or window is in closed position so as to form a tight joint.

Another object of the invention is to pro- .Vide a weather strip of the character above set forth embodying penetrative and receptive members, both of which are formed of resilient sheet metal thereby securing lightness and economy in the cost of manufacture.

In addition to the foregoing my invention comprehends improvements in the details of construction and arrangement of the parts to be hereinafter more fully described and particularly set forth in the appended claim.

In the accompanying drawings in which similar and corresponding parts are designated by the same characters of reference throughout the several views in which they appear V Figure 1, is a fragmentary view in elevation of a window and window casing illustrating the application thereto of my invention.

Fig. 2, is a detail view in transverse section of the rail of a window and illustrating the relation of the parts of the weather strip when the window is in open position, and

Fig. 3, is a similar view illustrating the window in a closed position.

With reference to the drawings, 10 indicates a window sash of the type which are hingedly mounted. For the purpose of my invention the window may be hinged for swinging movement upon either a horizontal or vertical .edge, the weather strip being mounted in either case upon the free swinging edge of the window. The window casing as indicated at 11 is cut away or rabbeted at one corner as indicated at 12 to receive the free edge of the window sash when in closed position. The penetrative member of the weather strip is indicated at 13 and receptive member generally at 1 1. The penetrative member is mounted upon the inner surface of the window and consists of a strip of resilient material extending the full width of the window and is bent to substantially ogee formation in cross section consistmg of a flat attaching portion 1 1 to be secured by rivets 15 o: the like to the window jamb having its opposite edge spaced away from the wlndow jamb and curved as at 16 to form the penetrative portion of the strip, the free edge of the strip being curved and directed again toward the jamb. The receptive member indicated generally at 14: consists of a strip secured at one edge to the window sash by means of rivets 17 or the like while the intermediate portion is curved away from the window to form a rib 18 and then curved again toward the window sash and formed with an inwardly curved portion defining a groove 19 to receive the curved portion of the penetrative portion of the member 13 secured to the jamb. The grooved portion 19 is formed upon the outer side of the receptive member of the weather strip and is designed to yieldably engage the curved portion of the penetrative memher when the window sash .isin a closed position forming a transversely yieldable interlocking airtight connection.

It will be noted that the free end of the receptive member bears loosely against the window sash and hence is adapted for sliding movement to an extent permitted by the inherent resiliency of the material from which the strip is formed. When the window sash is moved to closed position, the rib 18 first engages the curved portion 16 and further movement of the sash to closed position results in the snapping of the curved portion 16 with the groove 19 with the result that a tight joint is formed preventing the exit of heat from a room or the entrance of snow, air, or rain.

While I have illustrated and described my invention with some degree of particularity I realize that in practice various alterations thereover may be made, and I therefore desire to reserve the right and privilege of changing the form ofthe details of construction or otherwise altering the arrangement of the correlative parts'without departing from the spirit of the invention or the casing; of a weather strip composed of two resilient interlocking strips, one carried by the casing and the other by the sash, and each fixed at one edge and free at its other edge, the free edge of the casing member extending toward the sash, and the free edge of the sash member extending toward the casing, one or said members having a convexo-eoneave entering element. along its free edge, and the other member havlng a transversely yieldable, a concavo-convex seat along its free edge to receive said entering element and to snugly contact therewith throughout the length of the strip, the entering member being spaced from its support to provide for its yieldability.

In testimony whereof I afiix my signature in presence of two witnesses.
