. Beit-knojwn that I, Josnrn P. G 'AsER,

citizen of the United States, residing at 109 Third Ave, Detroit, in the county of whenconsiderecl in connection with the ae- Wayne and State ofMichigan, have.in vented certain I new and useful Improvements in VVeather-Strips, of which the following is a specification, reference being had therein to the accompanying drawlng. V This invention relates to improvements in weather strips of the class particularly adapted for casementwindows and the like to provide a seal against the entrance of moisture, air, dust, etc., between the sill of the frame or casing and the bottom of the swinging member or sash.

The object of the invention is to'provide a simple, light, cheap construction of this naturethat will be strong and durable in use and will afford an etlicient weather proof fitting or oint. 1

The invention will be understood from the hereinafter contained detail descriptlon companying drawings formingpart hereof and illustrating one embodiment of the invention. I

In the drawings v Figure 1 is a vertical" section of a casement window equipped with a weather strip constructed in accordance with the present invention and Fig. 2 is a detail perspective view of one of the strip elements or members.

In the drawings, I have illustrated, by way of example, a preferred embodiment of the invention. In this connection it will be understood that variations and minor changes in the particular construction shown, as will appeal to those skilled in the art and falling within the scope of the appended claims may be made without departing from the spirit of the invention. The special construction shown in the drawing comprises two cooperating metal strip elements A-B, shown in the present instance as applied respectively to the bottom rail of the swinging member A and to the sill of the frame or casing B. Both of the strip elements or members A-B are preferably formed from flexible sheet metal, such as sheet zinc, copper or the like.

The strip element A has a portion or flange a to fit against the under face of the sash rail, and at one side thereof a roll or flange a.

The strip member A is formed by curling one side portion of the strip out away from the portion a and around and backfthe pocket or roll portion having a general- The semi-circular shape in cross section. strip element A may be secured upon the face of the sash rail in any desired way.

Asshown, the strip element A is secured in place within the rabbet C of the sash rail by a row of tacks or similar fastening members a? passing through the portion or The sill strip B is formed by doubling the strip upon itself intermediate itsside. marglnal portionsto form an. upstanding part or flange b and the outstandingsi de flanges 6 b the upstanding part orflange Z) being bent. outwardly and up in a curve, and thence back to provide theme,

wardly extending roll or partially tubular portion 6 open atone side,-the exterior of said partially tubular or roll portion being of, a size and, shape corresponding v to the pocket or roll portion a of the strip member;

A to fit tightly therein. The strip member B is secured upon the 'upper face of the sill in anyv desired manner, for instance, :as shown by a row of tacks or hire fastening members b passing through the outstand-,. ing side flanges b 5.

When the window sash orswinging'memher is in closed position, as shown in Fig. 1 of the drawings, the flexible roll portion 5 of the member B fits tightly within the flexible pocket or roll portion a of the sash strip A, the outer face of the roll portion being in close fitting engagement throughout with the inner wall of the pocket or roll portion a, a channel 6 being provided at one side of the interfitting roll portions, and beneath the outer marginal edge of the roll portion 5, said channel 6' serving to assist in preventing the entrance of moisture, air, dust, etc., between the roll portions.

The weather strip hereinbefore described, it will be observed is extremely simple in construction and can be manufactured very cheaply from stock materials. The construction is of a durable nature and provides an etficient seal against the entrance of moisture, air, dust, etc., between the parts What I claim is:

1. The combination with a casement win- Specification of Letters Patent. Patented May 31,- 1921. Application filed September 27, 19 17. Seriallt'o. 193,523. i I

,po cket like portion a open at one 1 ing a tubular part open at one side, and the other strip element being provided with an upstanding part having at its upper end a tubular portion extending laterally to one side thereof and open at one side, the last mentioned tubular portion being of a size and shape'corresponding to the interior of the tubular part of the other strip element to fit within the same with its outer face throughout in close contact with the inner face of the other tubular part throughout the same when the window sash is in closed position, the open side of the inner tubular portion of one of the strips facing outwardly and providing a channel at one side of the inter'fitting tubular parts of the strips beneath the outer marginal edge of the inner'tubular part.

2. The combination with a casement window orthe like including a swinging sash, and a window frame having a sill, of a weather strip co'mprising'two cooperating strip elements constructed of flexible sheet metal and secured upon the bottom rail of the swinging sash and the sill of the window frame, respectively, one of said strip elements having a tubular part open at one side, said tubular part in cross section being of general semi-circular shape, and the other strip element being provided with a vertically extending lower part and a hollow substantially semieoylindrical roll at the upper end of said vertically extending lower part and extending laterally to one side thereof, said semi-cylindrical roll being open at one side, and conforming to the size and shape of the of the swinging sash and the sill of the window frame, respectively, one of said strip elements having a tubular part open at one side, and the other strip element being constructed from a strip of flexible sheetmetal, said strip being doubled upon itself intermediate its side marginal portions to provide a double wall flange with outstanding base flanges at opposite sides, the double wall flange having a lower flat part extending upwardly from its base, the two walls of said lower flat portion of the double wall flange extending in contact, and said flange having a tubular portion at the upper end of and extending to one side of said lower flat upstanding part, said last mentioned tu bular portion being open at one side, and being of a size and shape corresponding to the interior of the tubular part of the other strip element to fit within the same with its outer face throughout in close fitting engagement withthe inner face of said tubular part of the other strip element when the swinging sash is in closed position.

In testimony whereof I hereunto affix my signature in the presence of two witnesses,
