The present invention, while embodied in a telephone index of the loose leaf type, is of more general application to loose-leaf binder adapted for telephone index use, of simple, inexpensive and rugged construction, attractive appearance and complete eificacy for dependable instant opening to the selected sheet and which securely holds the sheets in position but readily admits of removal and replacement of the sheets without danger of deranging the apparatus.
In the accompanying drawings in which is shown one of various possible embodiments of the several features of the invention,

Fig. 5 is a transverse sectional view taken on line of Fig. 5, showing the binder in open position,
Fig. 8 is a view similar to Fig. 7, taken on line 8-8 of Fig. 5,
Fig. 9 is a view similar to Fig. '7, showing the bail in open position,
Fig. 10 is a view similar to Fig. 8, showing the bail in open position, and
Fig. 11 is a perspective view on a larger scale showing the sheet holder in locked position with the sheets removed, the better to disclose the details.
Referring now to the drawings, the base of the telephone index is a rectangular plate l2 preferably rounded at its forward corners and having a continuous downturned rim [3 along its forward and lateral edges, which imparts stiffness and security thereto as well as finished and ornamental appearance. At the rear end of the base there are a pair of opposed upstanding ears l4 embraced by the lateral flanges l5 of a flanged cover l6. Pivot means extends through the cars and flanges to mount the cover in hinged relation.
bail is desirably of nearly the width of the base and the bail legs are pivotally mounted coaxially with the cover hinge, In a simple embodiment shown, a pivot pin 2| may extend transversely through the cover flange I5 and the base ears [4, and through the bail legs 20, as shown.
Preferably the forward edge of the bail has upstanding fingers 22, equally spaced from each other and curved, as shown, into generally a U-shape, the ends of said fingers nearly abutting the upwardly curved rear flange 23 on the base in locking position of the bail.
The ball l8-2ll is preferably latched in locked position'by means of a latch plate 24 and that plate is desirably hinged at its lower edge by means of a unitary lug 25 fitting in a corresponding slot in the base. The latch plate 24 is urged against one of the bail legs 20 by a coil spring 26 about the pivot pin 2|. The latch plate is also provided with an inturned horizontal lug 21 to the rear of the upstanding finger tab 28 thereof. That lug arrests the forward unlocking movement of the sheet holding bail [8-20 by engagement therewith of a tooth 29 of the bail leg in the plane of the latter.
Desirably the bail is provided at one of its fingers 22 with an upstanding tab 30 for manipulation, by which the bail can be moved forward about its pivot 2| upon release of the latch 24, thereby to facilitate application and removal of perforated sheets. Preferably, the latch 24 is provided with an inturned lug 3i forwardly of the finger tab 28 which lug extends in the path of forward rocking movement of tooth 29 on bail leg 20 and so defines the position of the bail when in position for removal or application of a stack of sheets or cards in which position, as best shown in Fig. 10, the free ends of fingers 22 extend upward. The stack of sheets 35 has perforations 35 through which fingers 22 extend, and the perforation for the finger equipped with tab 30 is widened to permit passage of the latter. Preferably also the rear flange 23 of the base has upstanding curved fingers 33 thereon which intervene between the fingers 22 on the bail. Desirably the latch lug 3| is engaged by the lateral edges 34 of the stack of sheets 35 when in place and assists in maintaining the latter in registry. Desirably the, sheets are notched at 36 at their upper left hand corner for accommodating latch 24. Desirably also the base has an upstanding stud 31 fitting in corresponding notches 38 in the forward edges of the stack of sheets, further to assist in maintaining them in registry.
As thus far described, the device with or without the cover, is useful as a loose leaf binder of more or less general application.
The invention is, however, shown in one specified application as a telephone index, for which purpose, and for like analogous purposes, the base and cover are modified to attain speed and convenience of finding the selected sheet.
To this end the cover is provided with an index near one edge thereof, comprising preferably a longitudinal slot 38 which accommodates the index button 40 of plastic, if desired, which is provided with depressions 4! in its under surface riding along embossed tracks or runways 42111 the cover, laterally of the slot 39 and at opposite sides thereof. A pointer or index 43 integral with the button rides along the sequence of letters or numbers 44 imprinted at one side of the inner track 42. A sheet metal lifting hook 45 of U- shape has one leg 45 extending transversely across the inner face of the cover it and is lodged at its lateral edges in corresponding notches 41 near the inner ends of fingers 48 protruding from the button 49 downward through slot 39. A spring leaf 49 longitudinally of the slot 39 and transversely of the hook 45,, extends along the under surface of the cover l6 and has a central longitudinal slot 58 straddling the lugs 48 .on the button 40, a fastener stud through hook lug 46 aflixing the latter to the plastic button 49 and thereby confining the spring 49 in position. Preferably the cover is transversely embossed .as at 52 at the various letters and numerals, so .th at in moving the button along the slot 39., the spring 49 will ratchet along the embossments and be also impositively retained in position of adjustment.
The index sheets 35 are laterally cut away as at 53 below the hook 45, the A sheet having the shortest notch, the Z sheet the longest notch, and the intervening sheets having notches of graduated intervening lengths. The base plate 12 is preferably embossed slightly so as to provide a raised platform 55, upon which the sheets 35 rest with their notched edges protruding, and to afford clearance at 55 laterally of the platform below the entire stack of sheets, for the lifting end 54 of the lifting hook .45. Platform 55 also aids in stiffening the base.
As a further convenience, a cover latch 51 is provided for maintaining the cover closed, and spring means is provided to automatically open it upon release of the latch. Desirably the cover latch comprises an L-shaped button of plastic pivoted about a pin 58 at the forward end of the base l2 beyond the raised platform 55 and urged to upper or latching position by a coil spring 59 about stud 60 which rises from near the forward edge of the base and is telescoped into a corresponding socket 5-4 in the cover latch. Desirably also the cover I6 and flange are provided with a notch 52 at the forward edge which accommodates the latch 51, the nose 53 of the latter overlapping the cover in closed position. The opening impulse may be produced by a coil spring 54 about the hinge pin 2| beyond the bail at the side opposed to latch 24, said spring having an inturned end 65 reacting against the base and the opposite extremity 65 reacting against the cover.
The upstanding stud 31 is desirably mounted on the forward end of the cover latch 51 and it extends as above described into corresponding U notches 38 in the forward edges of the sheets of the stack.
The operation will be apparent but will be briefly summarized. To select any sheet, the button 49 is shifted along slot 38 to the corresponding letter 44 and the cover latch 51 is depressed, whereupon the spring 64 will urge the cover 16 to open position with the hook 45 lifting all sheets 35 above that of the selected letter and exposing the selected sheet. The cover may be closed after use and the cover latch 5! will snap thereover.
When it is desired to replace sheets, the button 40 is first moved to the lowermost or forward extremity, and upon release of the cover latch .57, the entire stack is lifted with the cover l6. Thereupon the latch 24 is shifted to the left by pushing against its finger tab 28. Finger piece 30 is then engaged to rock the sheet holding bail l820 forward until its tongue 29 is arrested by the lug 3| as shown in Fig. 9, at which time the U-shaped fingers 22 will extend upward and the stack of sheets or cards may readily be lifted from place and as readily replaced. Thereupon the sheet holding bail i829 is merely turned backward until the tongue 29 passes over the latch lug 27, thereby latching the sheet retaining bail in position. In that position the free ends of the U-shaped fingers 22 abut against the rear flange 23 of the base, and the rear fingers 33 on said flange intervene between said U-shaped fingers, so that the sheets are securely held against removal.
The sheets are also automatically registered in position in the insertion thereof, by the engagement of the lug 3! on the latch 24 with the left lateral edges 34 thereof and of the stud 3'! on the cover latch '51 with the notches 38 in the for- Ward edges of the sheets35.
The sheet binder feature of the invention may be utilized, it will be understood, with a narrow base strip along the hinge and without either the base or the cover and may simply serve as the binder of the book, or if desired, it may be used with a base l2 but without a cover, but preferably both base and cover are used as set forth.
It will be seen that the base is relatively fiat, so that desired entries may be readily and comfortably made upon any sheet thereon without interference from an upstanding flange.
As many changes could be made in the above construction, and many apparently widely different embodiments of this invention could be made without departing from the scope of the claims, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
