,, -.To all whom it may concern.-

Be it known that I, JOHN W. OLELAND, of the city of Decatur, in the county of Macon and State of Illinois, have invented certain new and useful Improvements in Loose-Leaf Books, of which the following is a specification.

The principal object of this invention is to provide abookbinding the covers of which are adjustable to hold a greater or less numin the appended claims.

In the drawings forming part of this speci- .fication, Figure 1 is an end view of so much of a book as is needed to explain my invention, the covers being shown therein at their closest approach when closed.- Fig. 2 is a similar end view showingthe covers adjusted apart to their extreme capacity. Fig. 3 represents a binding adjusted to width as shown in Fig. 1 and opened. Fig. 4 is a lan of an open binding, showing in detail t e various features of my invention, the covers being adjusted apart to their extreme capacity.

Fig. 5 is a cross-section on line a; in Fig. 4.

Fig. 6 is a perspective detail of certain features of the binding. Fig. 7 is a side view of the mechanism used to adjust the covers so as to vary the space between them.

The boards or stifi arts of the covers are shown at 1, and the eather or other outer la ers are shown at 2. Back extensions 3, W ich are preferabl continuations of the outer layers 2, exten beyond the hinge edges of the covers substantially as shown. The extensions .have some stiffness, but are sufiiciently elastic to assume the several positions shown in the drawings when forced thereinto by the swing of the covers and the resistance of the back. The function of the extensions 3 is to brid e the spaces between the covers and the bac when the covers are closed, and they are slotted, as shown at 3 in Fig. 6, to pass the supporting-plates 15 for the back 16. The edges of the extensions 3 are beveled in opposite directions, as shown at 4, so that one will override the other when the covers are open.

Plates 5 are secured to the. inner surfaces of the covers at the hinge edges thereof, and they have lugs 6 at their ends from which pivot-pins 7 project. I

The upper parts of bars 9 overlap, as shown in Fig. 4, and each has a hook 8 on its outer end which is adapted to engage a pivot-pin 7.

The lower parts. of bars 9 are cut away at and the back is sufliciently elastic to assume the different forms shown in the drawings. The back 16 and the extensions 3 of the covers are. each preferably stiffened by thin elastic metal sheets.

A shaft 19 is journaled near its ends in plates 14. It is provided with worms 20, which engage the worm-wheels 18, and on one end it is provided with a finger-wheel 21 or with other means for giving it rotary motion. The worm-wheel 18 is rigidly mount ed on screw-shaft 17, one end of which has a right-hand thread and the other a left-hand thread. The screw-threads enter the slides 11 and provide means for forcing them apart or drawing them together.

The overlapping arts of bars 9 are slotted, as shown at 10 in igs. 1, 2, and 3, and pins 12 extend one from each bar through the slot of the other, as shown in Fig. 4.'

Plates 5 are each provided with a set of mortises, as 22 in Figs. 4, 5, and 6, which re- 'ceive ends of the strips used to bind the leaves in the covers. Each binding-strip is composed of two separable parts slidably conjoined. The parts of the binding-strips are shown, one at 23 and the other at 26, in Figs. 4 and 5, and they are identical in construction. Part 23 has a longitudinal slot 24 and part 26 has a similar slot 27. Each longitudinal slot runs into a cross-slot, as 29,

and the ends of each of the cross-slots are en- 1 larged, as shown at 30, 31, 32, and 33 to permit passage of the heads of the pins 25 and 28 which are used to hold the parts slidably..to-' gether. The pin 25 extends upward from part 23'through slot 27 of part 26, and its ead is above-part 26. The pin 28 extends downward from part 26 through slot 24 of part 23 and its head is below part 23. The outer ends of the'parts composing the bind:

' ing-strips enter the mortises 22, and they are proper y ho d the leaves securely in place.

' In adjust/in the covers to {hotel more or fewer leaves t e finger vwheel 2 1 is turned one: way-or the other, 'impanting motion to the screw shaft 1 7 through worm and worm-wheel 18. Motion one direction wi-l h'eause the right and left screw thireads to draw the slides togetherand motion in the opposite "direction Wilh forae them'apart.

T covers are connected to the slides throug-h hooks 8 and pins 7, and so the covers partake of the motion of the slides. As the covers approach eachother or are movedapart the of the covers is book is closed.

vpins 25 and 28 of the two-part binding-strips slide in slots 24 and 2'? and the binding-stripsto lengthen or shorten to conform to thediistance between covers. Adjustment preferably effected when the TPhe pins 12 sliding in slots 9 perinit the covers to bemoved apart as -farafs the screwshaft 17 will properly operate, and-they effectually prevent :further separation.
