GEORGE B. RILEY, OF CINCINNATI, OHIO, ASSIGNOR TO THE TENA-CITY MANUFAC- TUBING COMPANY, OF CINCINNATI, OHIO, A CORPORATION OF OHIO.

LOOSELEAF BINDER.

' Application filed March 20, 1922. Serial No. 545,189.

T 0 all whom it may concern:

Be it known that I, GEORGE B. RILEY, a citizen of the United States of America, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in a Loose-Leaf Binder, of which the following is a specification.

An object of my invention is to provide an improved sectional ring for loose leaf binders.

Another object of my invention is to provide an improved and simplified mounting and operating means for the ring.

Another object is to provide a ring of this type upon which theloose leaves will not catch and be torn.

Another object of my invention is to center the ring in the eye in the loose leaf asthe eye passes the joint in the ring.

These and other objects are obtained by means described herein and disclosed in the accompanying drawing, in which:

Fig. 1 is a perspective view of a loose leaf binder carrying rings embodying my invention.

Fig. 2 is an enlarged fragmental trans verse sectional view of a binder and ring embodying my invention.

Fig. 3 is an enlarged fragmental plan view of a pair of'plates forming a detail of my invention.

' Fig. 4 is an enlarged sectional view on line 44 of Fig. 3.

Fig. 5 is an enlarged fragmental view of the separable abutment ends of the rings formingdetails of my invention.

My invention comprises the ordinary covers; 5 and 6 ofa loose leaf binder secured together in a hinged relation by any suitable means such as the back 7. The back carries an arched spring holder 8, having its side edges 9 and 10 turned radially inward, whereby

seats

11 and 12 are formed upon the back, upon which seats the outer edges of the

plates

18 and 14 engage. The plate 14 has formed on it

lugs

15 and 16, preferably disposed in pairs throughout its length, the lugs being formed by any suitable method as by being swaged so as to extend beyond the inner edge 17 of the plate 14, and so as to overlap the inner edge 18 of the plate 13, whereby the lugs of each pair of lugs cooperate in limiting the relative movement of the plates, and

preclude the separation of the inner edges of the plates. The plates have formed in them

slots

19 and 20 in which are mounted the lower ends of the

ring segments

21 and 22, each of which is substantially. semicircular and both of which are of substantially equal cross section. The ring segments are mounted upon the plates in any suitable manner such as by being soldered upon the plates. The upper or free end of the ring segment 21 has a conical recess, whereby a seat 23 is formed at said end. The ring segment 22 has ball or knob 24 formed at its upper or free end, the knob being of a larger diameter than the upper end of the ring segment 21. The knob 24 is adapted to extend partly into the recess in the ring segment 21, when the upper ends of the ring segments are brought into engagement, or are in locked position.

When the rings are in the positions shown in Fig. 2, the spring back 8 serves to move the inner ends of the plates downwardly or toward the back 7, thereby bringing the free ends of the ring segments into engagement with one another. The pairs of lugs on the plates cooperate with the en gagement of the ring segments upon one another in limiting the extent to which the inner ends of the plates may be moved in this direction. hen the ring segments are in this relation, and it is'des'ired to turn over a leaf carried by the rings, said leaf being turned from the right to the'left, the knob 24 centers the eye in the leaf so that as the eye passes over the outer edge of the ring segment 21, there is no possibility or likelihood of the edge of the eye catching upon the edge of the ring segment 21, thereby precluding injury to the sheet of paper. When a sheet-of paper is turned in the opposite direction, namely from left to right, the edge of the eye is brought into engagement with the knob 24 at the moment it passes beyond the upper edge of the ring segment 21, and the rounded contour of the knob serves to smoothly slide the eye onto the ring segment 22 without any likelihood or opportunity of damage being done to the sheet of paper. lVhen it is desired to remove sheets of paper from the ring, the upper ends of the ring segments are moved apart, thereby causing the outer ends of the plates to pivot upon the seats 11 and. 12, the lugs on the plates limiting the extent to which the plates may be moved, and thereby limiting the extent to which the upper ends of the ring segments maybe spaced.

What I claim is:

1. In a device of the class described the combination with sectional rings, one of which has a recess in its end, and the other of which has an enlarged head adapted to lodge partly in said recess and to extend outwardly laterally of said recessed ring section, of means to retain the ring sections in engagement with and in spaced relation to one another..

2. A'retaining means for sectional rings comprising a pair'of parallel plates, means to retain the plates in compressional edgewise contact, and lugs extending from one of the plates adapted to extend over 'oppo site sides of the other plate.

3. A retaining means for sectional rings comprising an'arched spring back, seats formed at the side edges of the back, a pair of parallel plates each having an edge in edgewise contact with the other, and having their other edges lodged in the seats, the back being adapted to yieldingly retain the plates incompressional contactupon one another, and lugs on one of the plates,

extending from the opposite faces thereof 7 and extending over the opposite faces of the other plate.

4. In a device of the class described the combination of a pair of sectional rings adapted to be inoved'into contact with one another whereby to form a complete ring adapted to hold loose leaves, the sectional rings having means at their places of contact to guide a loose leaf laterally on. the ring at the junction of the ring sections when a loose leaf is moved past the contacting ring sections, precluding accidental catching of the leaf on the ring sections at such junction.

5. A retaining means for sectional rings comprising an arched spring back, seats formed at the side edges of the back, a pair of parallel plates each having an edge'in edgewise contact with the other,: and having their other edges lodged in the seats, the back being adapted toyieldingly retain the plates in compressional contact 1 upon one another, lugs on oneof the plates,

extending from the opposite faces thereof and extending over the opposite faces of the other plate, and a ring. section mounted ment upon one another, one end having a recess diverging centerward of the ring section from the outer edge thereof and the other end having a globular head of a diameter in excess of the cross section of the recessedend for partial entry into the recess whereby a perforated sheet mounted on the ring will have the edge of the sheet at the perforation moved outwardly from the recessed end of the ring when shifted from one ring section to the other, for precluding catching of the sheet in thecrevice at the junction ofthe ring sections.

7 As a new article of manufacure a secional ring having ends for separable abutment upon one another, one of said ends having a convex abutment face of a larger cross section than the cross section of the other end for guiding a loose leaf laterally when moved past the abutting. ring ends.

8. As a new article of manufacture a ring comprising complementary rin sections having engageable ends provided with means for precluding relative lateral displacement of the ends when'engaged, one of said ends having a convex engagement face of a larger cross section than the cross section of the other end for engagement by said other end for guiding a loose leaf laterally when moved past the said ends of the ring sections.

In testimony whereof I have hereunto subscribed my name this 15th day of March,

1922. GEORGE B. RILEY.
