called loose leaf record books.

In binders of this type hitherto known the binding posts have been individually pivotally mounted on pintles at their opposite ends. The result of this construction has been that it is a difficult matter to hold all of the posts inthe same plane when it is desired to insert a new sheet in the binder.

Also binders of this character which have solid posts of necessity must always have the two covers a given spaced distance apart with the result that when there is in position in the binder a number of sheets less than the capacity of the binder they will not be firmly held in juxtaposition to each other and the book will be inconvenient to use.

Also when books of this character are used it is frequently necessary that a full complement of sheets be inserted in the binder or withdrawn therefrom and with the usual type of binder this is a difficult operation because it is hard to keep the holes in the sheets in alinement so that they may be passed readily over the posts. 1

The main object of my invention is to pro- I vide a binder in which the posts will be permanently held in the same plane irrespective of the movement of the posts with reference to the covers of the book.

Another object of my invention is to provide an adjustable fly leaf which will at all times hold in juXta-position the sheets in the binder irrespective of the number of such sheets to prevent undue wear of the perforations of the sheets.

Another object of my invention is to provide co-acting supplemental fly leaves whereby a full set of sheets may be inserted in or withdrawn from the binder with ra idity and ease.

Another object is to provide in loose binders of this type, which are largely used for filing photographed record prints, an eflicient means for compressing and thus straightening and flattening such prints, which, when fresh, are more or less crimped or warped.

Other objects and advantages relating to size, shane and arrangement of parts all as will more fully appear from the following description taken in connection with the accompanying drawings in which:

Figure 7 isa perspective view of my supplemental fly leaves.

Figure 8 is a erspective view, partial y broken away, of my binder and one of the supplemental fly leaves illustrating the way in which the fly leaves are used with the binder.

Figure 9 is a section on line 99 of Figure 7 with the supplemental fly leaves in closed position and with a set of leaves inserted therebetween.

My device consists of covers 1 and 2, joined together by a flexible back 7, formed of heavy cardboard or other appropriate material and preferably covered on the outside by a cover -3-- of leather or other durable material, and also preferably covered on the inside by a cover of an appropriate durable material. An end plate 5 is positioned on the inner end of cover 1 and is held in position by rivets 6- or other appropriate means. End plate 5 extends inwardly beyond the inner edge of cover 1 and is returned bent to form a cylindrical journal 8 for a purpose hereinafter to be described. Journal 8 is cut away, as shown at 9- on Figure 4, to receive the ends of the posts hereinafter to be described.

A second end plate 1 is positioned along the inner edge of cover 2 and is fastened therein by means of rivets --11.

, posts 13-- End plate 10 extends inwardly beyond the inner edge of cover -2- and is returned bent to form a housing 17-- for a pintlecarrying member hereinafter to be described. End plate 10- is cut away, as shown at -12 on Figure 5, to permit the insertion therein of posts hereinafter to be described.

Posts -13-- are preferably formed of an unbendable material rectangular in cross sc tion and having reduced ends -1 1 with holes 15 through each of the reduced ends 11. A plurality of posts -13, in this case shown as five, are rigidly secured by welding or other appropriate means to a cylindrical rod -16 and are positioned so as to be always in the same plane irrespective of the rotation of rod 16. Rod -16 is rotatably positioned in journal 8 of end plate 5 with the posts 13 positioned throu h the cut-away portions 9 of housing 8.

A pintle-carrying member -18 carrying a plurality, in this case shown as five, of pintles 19 is slidably positioned inhousing -17 in such a manner that in one position the pintles -19- will extend across the openings 12- and in another position will be withdrawn from openings 12. The

position, extend into openings 12 for the reception in holes -15- of pintles 19'- for the purpose of locking the posts in position. Pintle-carrying member -18 has at one end a handle 20-- by which it may be moved back and forth in housing -17. lock -21- is positioned adjacent to pintlecarrying member 18-. Pintle-carrying member 18- has in the edge adjacent to lock 21- a slot -22 for the reception of bolt -'23 of lock 21-. When pintlecarrying member 18 is in position with intles -19 in holes 15, as shown in igure 4, the bolt -23 will be in slot 22 and will prevent the retraction of pintlecarrying member 18. When it is desired to retract pintle-carrying member 18- a'key, not shown, is inserted in lock 21- and bolt -23 is retracted and held in the retracted position by a detent 24,

as shown in Figure 5, and pintle-carryingv member --18- may then be retracted to removev pintles -l9ifrom holes 15-- thereby releasing posts -+13-. When pintlecarrying member 18- is retracted to its outward position the inner edge of slot 20 will contact with detent 24 which will release bolt -23. Bolt --23- however, can not enter slot 22- until pintle-carrying member 18 has again been pushed forward to bring slot 22- in registration wlth bolt -23. When this is done bolt -23 will automatically enter slot -22- and lock pintle-carrying member -18-- in posltlon.

when the binder is in the closed" A action of springs Adjustable fly leaf 25- made of heavy canvas or other appropriate material and of approximately the same size and shape as cover -1-, carries at its inner edge a h0us-. ing 26 secured thereto by rivets 27 or other appropriate means. Housing 26 is provided with a plurality, in this case shown as five, of holes 28 to permit the passage therethrough of posts 13. A spring locking member 29 is positioned in housing -26 and consists of a metal strip -3Q- which carries on its end a spring 31-. Spring 31 being so positioned that in the locked position it will extend into a hole 28 sufficiently far to press against a post -13- to hold fly leaf 25-- from movement on post 13-. Another strip ing 26 opposite to that in which strip 30 is positioned and carries on its end a similar spring 33 which in the locked position extends into another opening -28- sufficiently far to press against another post -13 to also prevent movement of fly leaf 25-. Strips 30 and 32 are connected to a bell-crank 3L by means of links -35'- and 36. Bellcrank 34-- is pivotally mounted on a pin 37 which is positioned in housing 26- thereby forming a toggle joint betwe'en strips -30- and 32. Springs 31 and 33- have their ends bent upwardly so that when fly leaf -25- is placed on posts -13- it may be pressed downwardly against the -31 and 33-. The ends of springs 31 and 33- which bear against their respective posts -13 being bent upwardly will exert a pressure against such posts -13 when it is attempted to raise fly leaf --25--, and in order to raise fly leaf 25 it will be necessary to rotate bell-crank -3 1 which through links --35- and 36- will retract strips -30- and-Q12?- and will withdraw springs -31 and -33' from registration with their respective posts -13-, and the fly leaf can then be raised.

Supplemental fly leaves -38-- consist of a bottom portion -39- and a top portion -40 both constructed of a flexible heavy paper or other appropriate material and are of approximately the same size and shape as cover 1-. Bottom portion 39 carries on its rear edge a plate -4:1 which is provided with a plurality of holes, in this case five, 42- to permit the passage therethrough of posts 13-. A plurality, in this case shown as four, of cylindrical posts 43 are rigidly positioned in plate -41- in spaced relation and are of an appropriate height to extend through the full complement oft eaves .44, when my binder is filled to capacity. Posts 43- are internally threaded on their upper end, as shown at -45- in Figure 9, for the reception of -32 is positioned in the end of housscrews -46 for a purpose hereinafter described. Top portion 40-' carries on its rear edge a plate 4:'( which is provided with a plurality, in this case shown as five, of holes 48 to permit the passage therethrough of posts 13-. Plate --47 is also provided with a plurality, in this case shown as four, of cylindrical holes 49- to permit the passage therein of the upper ends of posts -43--.

Operation 7 of posts 13- and posts 43, may then be placed in position on p0sts 13'- or removed therefrom after which adjustable fly leaf -25- will be placed in position on pos -.-13- on top of sheets -44 and pressed downwardly until it contacts with the upper one of sheets -4=4 to hold such sheets in juxta-position. Cover 2- will then be replaced on posts -13 and pintle-carrying member -18- pushed inwardly to lock cover.

2- to posts -.13-.

When it is desired to temporarily withdraw a full complement of sheets -44- from the binder, cover -2- will be removed from posts -'13 and adjustable fly leaf-25- also removed from posts 13- in the manner just described. Bottom rtion -39 will then be placed on top 0 sheets 44 and posts -43 inserted through holes -51- and bottom portion --39- pressed downwardly until it contacts with the upper sheet of sheets 44-. Bottom portion 39'- carrying sheets -44- may then be lifted from posts 13. Upper portion 40 will then be placed on the bottom one of sheets with posts 43-- extending into holes -49 and screws --4=6 will then be placed in the threaded ends of posts -43 to lock drawing and the binder again laced in the locked position in the manner heretofore described. I claim:
