6 To adjust the gate segments 5,5' to the proper width, to
7 fit in a doorway opening, the slots in center bar of gate seg-
8 ment 7,7' are aligned and in side to side contact, as shown in
9 Fig, 14 and are fastened together by means of idler ~langed spool
comprising a flanged spool segment and wherein the body portion
32 of the flanged spool segment is of such dimension to freely
2 slide in slots 7 in center bars of grate segments and the flanges
13 21 extend beyond the width of the slots. In addition to above
14 r flanged spool segment or idler flanged spool the gate segments
are further held together in side to side contact by means of
16 elongated spool body section 31, which is of such thickness to
17 slide freely in slots 7,7' in center bar of gate segments 5,5'.
18 On tightening the flanges 15, the gate segments 5,5' are held
19 rigidly ad~usted to width, when spool section 18 is inserted in
slot holes 34 in slots in center bars of gate segments.
21 To adjust the width of the gate segments 5,5', before
22 fastening the flanges 21 on the spool sections 32 fitting in
23 slots in center bar of gate segment, the flexible reed 14
24 fastened on one end to flange 15 and the opposite end of the
