<p>The frame is for tilting and swinging windows or doors. A closing plate is mounted in the bottom corner on the upright blind frame bar. A tilting bolt is mounted on the bottom of a length adjustably mounted drive bar on the wing, with a stop edge fitting against an eccentric stop bolt. The stop edge on the tilting bolt is aligned between its swivel axis and the stop bolt axis; in its stop setting it tends to twist the eccentric stop bolt in the direction for increasing pressure.</p> |
