This invention relates to loose leaf binders of the post type, and has for its main ob ectto provide an inexpensivebmder of simple design that is easy tooperate and of such construction thatthere is no possibihtyof the leaf-clamping members slipping or movlng relatively toeach other so asto relieve the clamping pressure on the leaves when the back binders and various changes can be made in the construction of the cooperating parts of the binder Without departing from the spirit of my invention. I p Y Y Figure 1 is a top plan vlew'of a, closedback binder constructed in accordance with my invention showing the covers of the b nder open. Y 4

In the form of my invention shown n Fig uresl, 2," 3, and the binder, comprises two opposed leaf-clamping members Aand 1A, hinged covers'Bg and B carried by said leafclampingmembers, solid posts C on there spective leaf-clamping members arranged. in staggered relation, and adapted, to pass through holes inthe rear edge portions of the leaves 00,80 as to prevent the leaves from shifting relatively to the leaf-.clampingmeinbers, and back members "D andD carriedby the leaf-clamping members Acand A, respectively, and disposed at substantially right-angles to same so asto form a solid back for the binder that protects the rear:

.Figure 9 is a sectional view, taken onthe and constructed so that they edges oftheleaves. \When the binder is :in 1ts normal closed condition the leaf-clamping members A. and A firmly bind the leaves to gether, and when it is desired to open the I.

binder preparatory to removing or insertingleavesrsaid leaf-clamping members aresep-- arated or-moved posts Cfrom theholes inthe rear edge por tions of the leaves. Y 7 i a My invention consists of a novel means for preventing relative movement ofth'e'xleaf clampingmembers A and-A when the binder is locked or closed. Said means, briefly d'e} scribed, consists of a guide carried by'one of" the leaf-clamping members,

a slide reciprocatingly mounted in said guide and carried b the other leaf-.clampingv member, .and'ade' vice for clamping said slide in jsaid guide.

The particular shape, of said guide and slide is immaterial; various kinds andforms of de i vices may be used to clamp-the slideiriftheguide, the binder maybe provided with one cooperating guide-and slide, or a plurality of cooperating guides and slides, and said guides" and slides may bearranged invarious ways In the binder shown in Figures 1 to 40f the drawings, the leaf-clamping'inember A is provided at. its ends'with twdlaterally; projecting guides E and Ethat are disposed at right-angles'to same, as shown in Figure 1,,and the leaf-clamping member A is pro? videdfat its' en'ds witht'wo right-angularlydisposed slides F and F that are reciprocatf ingly mountedfin said guides: Said guides are preferably of the cross-sectional shape apart soas to withdraw the shown in Figure 2, so that they will embrace locking devices on the guides'arranged inlong'itu(finally-disposed grooves 1 in the slides can be turned or oscillated so ZtstO exert frictional pressure on'the walls of said. grooves. Theilocking device 2 of each -guide. is carried; by the guide in whichthe slide moves. said lock ing device 2 is oscillatingly mounted in the the drawings, said locking means consists of I guide, and it'is. provided withaflever 3 or other operating member by which t can-be 5 set in one position, referred to asits unlocked position. wherein-it is disposed in such rela tion with the groove 1. in the slide that it will f' .FFIC E. I V

not exert any; appreciable friction on same,

" or set in another position, referred to as its locked position, wherein it bears tightly against the Walls of the groove 1, and thus effectively prevents the slide from moving relatively to the guide- When the binder is unlocked, as shownin Figure 3, the locking devices 2, are disposed longitudinally of the grooves 1 in the slides F and F, thereby permitting said slides tobe moved longitudinally ofithe guides E andE to move the leafv clumping members A and-A towards or away from each other, and when the binder is in its clwed orlocked condition, as shown in Figure 4, the locking devices2 are disposed V crosswise of the groovesl, so that the ends of same will exert suflicient pressure on the walls ,of'said grooves to securely lock the slides F and F in the guides E and E; The operating levers3 are arranged on the outer sides of'the guides E and E in a position v where theyrcan be easily manipulated, and

each of said levers is preferably provided withcaihead'piece 3 that has two fiat faces 4 andli thereon, which are adapted to cooperate with a flat-faced abutment 6 on the guide with which the lever is associated. A friction' washer 3 is preferably arranged between each of the. head pieces 3 and the adjacent surface of the guide so as to assist in holding the locking device in the position into which it has been moved. When the locking devices are manipulated to unlock the binder'the fiat faces 4 on the head pieces of the operating levers 3 strike against the abutments 6, and thus determine the position (If the locking devices 2 in the grooves 1, and whensaid levers are turned into the position shown inFigure 4 so as to render the locking devices 2 operative, the fiat faces 5 on the head piecesor said levers strike against the "flat-faced 'abutments 6, thus indicating to the operator or user that the locking devices 7 2 have beenturned 'far enough'to lock the slides. The guides and slides are herein illustrated as being connected to the leaf- "clamping members that carry same, by lat-- (wally-projecting portions? at the ends of said guides'provided with notches for receiving lllgs:8 on. the leaf-clamping members 7 that are bentinto overlapping relation with said portions 7, as shown in Figure 5.

In the form of my invention shown in Figures 6 and 7 the devices that are used to lock the slides in, the guides consist of binding screws Qfrotatably mounted in the guides and arranged so'as to exert pressure on the slides in a direction tending to force said slides lat-- erally away from their cooperatingguides, and thus clamp "said slides tightly against side walls 'on the guides that limit the out wardmovement or lateral movement of the slides." -Each of said binding screws 2 is provided'at its outer end with a head piece 9 that can either be of non-circular shape so as to enable itto be turned with a wrench or the'like, or if desired, said-head piece can be provided with holes 9, as shown in Figure 6, for receiving pins 10 on a removable key 10, as shown in Figure 7.

In Figures 8 and 9 Ihave illustratedthe guides of the binder equipped with locking devices 2 of the same kind as those used in the binder shown in Figures 1 to 4;, but cons'tructed in such a manner that a' removable key 11 can be used to turn said locking devices into their locked or unlocked positions, said locking key having pins or prongs 11 that are adapted to be inserted in holes 12 in head pieces 12 attached to the locking devices and arranged on the outer sides of the guides in which the slides'reciprocate. If

desired, said head pieces can be providedwith right-angularly-disposed' flat faces 4- and-5 that are adapted to co-operate with flat 7 faced abutments 6 on theguides.

A 'binder'oft-he construction above described is easy to operate, it is inexpensive to manufacture and when it'is locked, the leaf-- clamping members cannot separate or move in a direction to reduce the clamping pressure on the leaves.

Having thus described my invention, what secure by 'Let- I claim as new and desire to ters Patent 1s:
