"This invention relates 'tofla'new and ima posts is always done by the use of some sort of provedloose leaf binder of the type common 1y called a flexible post binder;

7 In devices of this description it is desir able tohavea binder in which the available length of posts can be varied. That is to say, abinde'r in which'the amount of available posts between the "covers can be increased from time to time as'new sheetsare inserted. We are aware that binders, to accomplish this specific purpose, have already been made but'in every binder of this type heretofore known ithas been difficulty-if not impossible, to insertnew sheets or to remove sheetswithout first increasing the length of'the available posts. The increasing of thelength'of the akey device and and in consequence considerable amount ofwork has to be done before an additional sheet can 'be'inserte'd, ora

' Operation.

When rod is rotated in the proper direction to carry nuts "59 and to the centerofhousing 2' a considerable portion of flexible posts 27 and 28'- will be drawn and'held inside of housing 2. When it is desired to increase the available length of flexible posts -27 and ..28- between housings 1 and --2-, rod 55 may be rotated to the extent. desired thereby moving'nuts59- and 60 towards the ends of housing -2- and fore-V the action of springs -3land 37-.-

When the sheet has been inserted or-withdrawn the. housings may be released and are immediately returned totheir former position under action of springs -..3% and If it is desired to lock the book so that this just described operation can not take place, the screw 19- isrotated in the proper direction to carrynuts -28 and 24-,inwardly against flexible posts +27- and 28 which will prevent any movement of these posts.

It will be understood that this desirable result ofhaving'a flexible post binder so constructed that one end of each post is normally held in position by the action of a spring can be accomplished in Ways other than by the specific construction just described. For although We have shown and'described a spe cific structure and form of part as illustrative of an embodiment of our invention, we do not I desire to restrict ourselves to the exact shape,

formv or relation of parts as various changes may be made within the scope of the append- 1 ed claims.
