FBAZEUR S. SLATER AND AUSTIN J. MILLER, 013 DETROIT, MICHIGAN; SAID SLATER ASSIGNOB TO SAID MILLER WEATHERPROOF METAL CASEMENT WINDOW Application med November 24, 1930. Serial No. 497,647.

This invention relates to a weather-proof metal casement window.

It is the object of this invention to produce a weather-proof metal casement window and this has been achieved'by means of a resilient weather strip which can be readily and simply attached to the easement frame. erably comes in the form of a strip of sponge rubber, 'one face of which is adhesive and.

' method of assembly of the weather strip to the easement frame.

Referring more particularly to the drawing, the easement window assembly consists of a casement frame generally designated 1 and the casement window generally designated 2.- The casement frame 1 and window frame 2 are of\ metal construction and the accurate only within commercial limits it follows that the joint between the amb face 7 and the inner face 8 of the window frame is not a weather proof joint. Further, since the engaging faces 7 and 8 of the easement frame 1 and the window frame 2 extend completely around the casement and window frames, that is, along the top and bottom as well as both sides, and since the window frame 2 is hinged to the easement frame 1 This resilient weather strip prefas at 5 and 6, it necessarily follows that if the face 7 of the casement 1 extending between the hinges 5 and 6 is weather-stripped by a strip that is not sufliciently resilient and distortable to give appreciably when the window is closed that the outer edge 9 of the window frame 2 will be spaced from the face 10 of the easement frame 1 and thus permit the rain, sleet, and air to pass through the easement from the outside. Hence, to obviate this difficulty the easement frame 1 is weather-stripped by means of a thin strip 7 of resilient material which is highly distortable and has high come-back qualities and is preferably fabricated from sponge rubber, rubber similar to that used in rubber bands, and any other type of vulcanized rubher which has the above mentioned qualities.

This weather strip may be generally designated 11 and consists preferably of a continuous strip of sponge rubber 12 which is provided with a suitable adhesive 13 on one face thereof, this adhesive preferably having a rubber content and being of the type that will adhere both to metal and to rubber.

Preferably the weather strip 11 is wound about a mandrel 13 as shown in Fig. 3. Hence, to prevent the adhesive 13 from integrating or sticking together, the successive convolution of a sponge rubber strip 12 and adhesive 13 is covered by a continuous strip 14 which will not adhere to the adhesive 13. This strip 141 is preferably a fabricof the type known to the trade as Holland cloth. The application of the weather strip 11 to the jamb face 7 of the casement frame 1 is nicely brought out in Fig. 3. To assemble the weather strip to the easement frame 1 the non-adhesive cloth strip 11 is peeled back to expose the adhesive face 13 of the sponge rubber strip 12. The exposed adhesive face of the sponge rubber strip 12 is then pressed against the jamb face 8 of the casement frame 1 to which it adheres. lVhatever length of weather strip is desired is unrolled from the mandrel 13, the cloth 14 rolled back and when a sufficient length of weather strip has been unrolled it is simply severed from the weather-strip roll.

The roll of weather strip is very easy and convenient to handle and owin to the simplicity of the removal of the (3 th 14 from the adhesive face 13 of the weather strip 12, the weather strip 12 is readil assembled to a window casementand there ore does not require the services of a skilled artisan. Owin to the high distortability and high comeack qualities of the sponge rubber strip 12, a complete seal along the top and bottom as well as the side edges of the frame 1 and the window. frame 2 can be attained without in any wise impairing the function ofthe hinges 5 and 6 or preventing the win-' .dow frame 2 from being completely closed in relation to the casement frame 1.

' Claims: y

1. A Weather strip for a casement window or the like comprising in combination of a strip of resilient rubber material having an adhesive face, a mandrel upon which the said resilient rubber material strip may be wound to form a roll and a non-adhesive strip contactin with the adhesive face of 4 the resilient ru ber material strip throughout its length whereby successive convolu-- tions of the said weather strip are prevented from adhering one to the other.

2. A weather strip for a casement window or the like comprisingin combination of-a 3o continuous strip of sponge rubber having an adhesive face, a mandrel about which the sponge rubber strip is wound to form a roll, and a non-adhesive fabric continuously in contact with the adhesive face of the said sponge rubber strip to prevent the sticking of one convolution of the sponge rubber strip to the other whereby the said sponge rubber weather strip may be readily applied to the easement window to weatherproof the same 7 by peeling back a portion of the non-adhesive strip to expose the adhesive face of the said sponge. rubber weather-strip, which adhesive face may be applied to the window casement and the length of weather-strip required severed from the roll.

' 3. A weather strip for a window casement or the like comprising in combination of a continuous narrow strip of spongerubber, an adhesive applied to one face of the sponge 5 rubber strip and a non-adhesive strip continuously in contact with the adhesive face of the said sponge rubber strip whereby the sponge rubber strip may be rolled up with the successive convolutions of the sponge'rubber a strip in non-sticking relation. In testimony whereof we 'afiix our signa' tures.
