LOOSE-LEAF BINDER.

Specification of Letters Patent.

Patented Dec. 27, 1921.

Application filed August 12, 1919. Serial No. 317,036.

To all whom it may concern:

Be it known that I, LEON B. STODDARD, a citizen of the United States, residing at Baker, in the county of Baker and State of Oregon, have invented certain new and useful Improvements in Loose-Leaf Binders, of which the following is a specification.

This invention relates to a binder for loose leaf records, tariif files, maps, etc., and an object of the invention is to provide a binder of this nature which will bind sheets provided with openings or slots punched near one edge. In making up loose leaves for various types of records, some are provided with holes or perforations near one edge, while others are provided with vari ous forms of slots, and each leaf having the distinctive type of opening therein is designed for use with a particular type of binder which sometimes results in considerable inconvenience to the user, owing to the failure to have the proper type of binder, and an object of this invention is to provide a binder of the spur type, which will effectively bind leaves provided with various types of perforation.

Another object of the invention is to provide a binder as specified which comprises a pair of hingedly connected sections, each carrying, at its free edge, a plurality of arcuate spurs adapted for seating in recesses in the other or companion section, and the spurs upon one section are disposed staggeredly to the spurs upon the other section to permit the entire closing of the sections if desired, and also to provide binder strips having convex outer surfaces along the free edges of the hinged members, which strips are adapted to form line binding contact with the leaves to securely bind them .in the back or, binder.

A further object of this invention is to provide a simple and efficient form of locking mechanism for locking the hinged sections in leaf binding position, the said lock comprising an arcuate segment carried by one section and provided with ratchet teeth on its concaved surface, which ratchet teeth are adapted for engagement with companion ratchet teeth formed upon the convex upper surface of a locking lug. to lock the sections in various adjusted positions, and further to mount the said locking lug upon a flat spring, which normally urges the lug into locking position with respect to the segnents, and which permits depression of the locking lug to release the locking engagement with the segment.

A still further object of this invention is to provide the locking ratchet teeth upon the lug at an angle, and to adjustaoly support this locking lug providing adjustable connection with its operating pin to permit longitudinal movement of the lug to vary the pressure of the teeth thereon with the teeth of the locking segments, and to compensate for wear upon these locking teeth.

Other objects of the invention will appear in the following detailed description taken in connection with the accompanying drawings, forming a part of this specification, and in which drawings:

Figure 1 is a plan view looking into the binder in an open position.

Fig. 2 is a cross section taken on the line 2-2 of Fig. 1.

Fig. 3 is a fragmentary longitudinal section through the binder illustrating the locking lug and its operating pin.

Fig. 4 is a cross section through the binder similar to Fig. 3 only showing the sections partly closed.

Fig. 5 is a detail perspective view of the locking lug, and

Fig. 6 is a detail perspective view of the locking segment which coacts with the said locking lugs.

Referring more particularly to the drawings, wherein like characters indicate like and corresponding parts throughout the several views, the two sections 10 and 11 of the binder are hingedly connected by means of hinges 12, and they have rounded outer surfaces, to present an artistic appearance, as well as to prevent the provision of corners thereon. The hinged sections 10 and 11 have facing portions thereof cut away to accommodate the locking construction. However, a portion of their facing sides as indicated at 13 is adapted for facial abutment when the sections are completely closed. Outwardly of these portions 18, the inner facing portions of the sections are cut away to accommodate or receive the loose leaves to be bound by the device. The sections 10 and 11 are preferably covered with any suitable type of fabric as indicated at 14 which fabric also serves to connect the covers 15 to the sections 10 and 11 as clearly shown in Figs. 2 and 4 of the drawings. Along the inner surface of each of the sections 10 and 11 near its outer edge is positioned a binding bar 16,

preferably of metal, and presenting a convex surface for engagement with the leaves to be bound by the binder so as to provide line binding engagement witl a leaf. These strips 16 carry arcuate spurs 17 upon one strip being dispose-c z with respect to the spurs upon. t strip as clearly shown in 1 of ings. The strips 16 and also the secti and 11 are provided with o; ninos 18 therein which are ad recei ti o spurs 17 of the other s when the se tions are partly or wholly closed, The enter the spurs 17 are preferably shar, shown at 18 a d {PG adapted to through the pew -cns o1 op the leaves to be bonnc by tie b desired, they em. or to thei ends 18 be used as ing the leaves to permit tl r o; the binder.
