devices, in which leaves' are bound on postsv or guides; and the object of my invention is to provide a simpler, more durable, and more efficient structure. A

A'Ihe'invention consists of novel features and parts and combinations ofY the same, which will be more fully described hereinafter and then point/ed out in the claims.

A practical embodiment of the invention l is represented in the accompanying drawtiti ings which are part hereoi1 and Ain which similar numerals of reference indicate the Corresponding parts 1n all the View s.

Figure 1 is. aperspective view of thel cover and leaf-retaining portion of the book; Fig. 2 a rear elevation of the'book with the back cover removed; Figs. 3 and 4 detail sectional views; Fig. 5, a plan of the locking slide; Fig. 6, a detail view showing the combination between a retaining 'member and. a leaf; Fig. 7, a plan of a. leaf; Fig/8, a perspectiveJ view of the pamphlet attachment; Fig. 9, a perspective `view of the spring-binding attachment; and Fig. 10 a perspective view of a filling strip.

The book consists of two binding parts, swingingly connected at the rear edges'ol their bases to a connecting element in the 'back and -to top and bottom covers; of loosely attachable sheets; of loosely attachable iilling elements; and of loosely attachable spring-binding elements. One binding part consists of a stili base 1Q, having set therein the lockable pins or posts 3- and 4 and being recessed to admit the members 1 and 2. These retaining members 3 and 4 are preferably `circular in cross-section, circularly curved so that their axes form quarter circumferences lengthwise, and provided' with approximately hemispherical free ends and transverse holes near thereto for admitting the penetrating portions of the locking slide. l,g'llhe other binding' part comprises a locking slide 5, a casing 13 therefor, elements 9 for supporting firmly the bars of the casing, and posts'l' and 2. The casing 13 is preferably composed of ,a single piece or plate bent around'in the form of two iat bars with a curved' connection on thel rear edge. These bars support the casing on top and bottom, are held firmly apart by the elements 9, preferably cylindrical, and are firmly connected by the retaining members 1 and 2 which preferably penetrate said cylindrical elements 9. By penetrating the Cylindrical elements 9, the retaining members l and 2 are given a very 'stid' and solid setting foundation .through the entire thickness of thecasing 13. The curving of the' rear portion of the easing 13 especially adapts it as a hinge for the double hinge action lwhen the book is opened for the removal of leaves.

The locking slide 5 isslotted to lreceive the velement 9 and the post 2, thereby slidabiy holding itself in position. At the inner end of theslide are free projections adapted to hold this end of the slide-slidably in posi` ltion with the assistance of theelement. 9 and, the post l. By those two sliding engage ments the slide 5 is held against anylateral movement. This enables the casing 13 to bev of any width and makes it unnecessary to support the slide 5 thereby on either side. The projecting piece 16 is laterally resilient and has a knob for encountering the element 9 around the post 1 as the slide is pulled out. The necessity o-overcoming this resilient' engagement in pulling out the slide makes it impossible for it to jar loose. The slide is further provided with inside openings for admitting and containing the lockable posts 3 and 4, in which openings are set the penetrating pieces 14 and 15, preferably cylindrical and pointed, for penetrating the transverse holes in posts 3 and 4 and Alocking the book. To give the properspring tension and to make the structure simpler, the same'inside edge extends around the retaining members 3 and 1.

rThe outer bar or" casing 13 1s provided with holes 18, reeraloly circular, adapted to admit the en s of the retaining members 3 and 4, to pocket and engage them as shown in Fig. 4, and to hold them in exact position laterally and longitudinally to admit the penetrating. elements Y 14 and 15 through their transverse holes. The inner bar oi the casing V13 has an opening 17, preferably elliptical, for admitting the post 4 diagonally and a similar opening for post 3. These openings 17 have their minor axes but slightly larger than the diameter of the posts 3 and 4, so that the bar will' support the penetrating pieces 14 and 15 immedi` ately after'they have penetrated the posts 3 and 4. y

The posts 1 and 2 are similar in shape to posts 3v and 4,. but preferably smaller in cross-section. llhe smaller the cross-section the less friction there is when the posts l and 2 pass through the leaves, and the better'l the operation in opening and closing the binder for removing leaves. rlhe approximately hemispherical free ends are espedoubled portions are then fastened securely to the inside edges of the covers respectively. rlhis makes it impossible to tear the outer rear edges of the boards 6 away from cover` 7.

fi single piece of A- flexible material 7 is used to Icover the boards 6 and to connect the two parts. 'lo enable the curved posts 1 and 2, and 3' and i to swing into and out of the leaves readily, their axes must remain approximately in the same cylindrical surface. To accomplish this the portion of the cover 7 between the bases 10 and 13 must ordinarily be wider than the chord of the quarter `circle on which the posts are curved, which is lthe thickness of the book inside the covers. Tomake this extra width small, the` bases of the posts 1, 2, 3, and 4, may be set such a distance-from the back edges of the baseslO and l13 that when the free ends of the four posts are in a line, the distance between a line run through the bases of the posts y1 and 2 and a line run through the bases ofy the' posts 3 andi. 4 will. approximately equal the diameter of thecircleon whose circumference the posts are' curved.

ATo accomplish this result, the distance` of the posts from the back edges of their respective bases should be approximately seventwenty` fourths of the thickness of the book, making the extra width in theback cover approxi` mately nine-one-hundredths of the thickness 'r of the book. From this it is evident that with books'less than two inches thick, the

extra width of the back cover would be scarcely noticeable with 'this arrangement. In caseof thick books, fto avoidA too` much metal 'in the bases`,the extra width in the back may be increased to two-tenths the books thickness, in which case' the distance Lieder? from the bases of the posts to the swinging vedgesneed only be one-sixth the thickness 1 of the book.

By making the holes 19, 20, 21, and 22 in the leaves 26 elliptical, with their minor axes approximately the diameter of the inside edges, and the passage of the posts through the leaves when the binder is opened is made easier. rlhe ratio just stated between the major and minor axes of these holes is based upon the pins being curved on .a quarter circumference` and being set with the tangente at an .angle of 45 with the bases.

, To provide acompact and4 simple means for spring binding, the strip 11 is used, preferably of wood, provided with holes for admitting the leaf-retaining members of the binderandy with a plurality of pieces 25, of resilient material, like soft rubber, of even thickness. TQ cooperate with this springbinding strip l employ the filling strip 12.

rop ailing and binding in law books .and

the like, l employ the dummy booklet 24, ,composed of a plurality of leaves fastened together on one edge and provided with holes to admit the leaf-retaining members of the binder. rhis dummy booklet may have 'a strip 23 of resilient material for its binding edge.
