TEMPORARY BINDER.

sPncIFIcATIcN formng part of Letters Patent No. 587,988, datd August 10, 1897. I

Application filred April 26, 1897.

T0 aZZ whomz it may concern;

Be it known that we, HENRY C. MILLER and J ULIUS BAUER, of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a'new and useful ImproVement in Temporary Binders, of which the following is a description, reference being had tothe accompanying drawings, which are a part of this specification.

Our invention has relation to improvements in temporary binders.

The invention relates more particularly to that class of binders in which leaves ale plaggd and seeured between the side pieces constituting the cover of a book and firmly locked therebetween and when unlocked any one or more of the leaves maybe remoVed and others substituted therefor.

The invention will be found of especial utility when the leavesare so arranged as to constitute what is commercially known and designated as a perpetual ledgeiz The primary object of our invention is tol provide an improved construction whereby the leaves can be readilyinserted or extracted from any part of the book and when inserted by means of a simple manipulation can be securely held in place.

With the above primary object and other incidental objects in View the invention consists of the devices and parts or their equivalents, as hereinafter more fully set forth.

In the accompanying drawings, Figure 1 is a perspective View showing a complete binder embodying our invention. Fig. 2 is a longitudinal sectional View of Fig. 1 with parts broken away. Fig. 3 is a section on the line 3 3 of Fig. 2. Fig. 4 is a horizontal section on the line a 11 of Fig. 3, and Fig. 5 is a detail view of the looking-key.

Referring to the drawings, the numeral 6 indicates the under side piece and 7 the upper side piece constituting the cover. The rear binding-piece 8 of the under side G is provided with the upwardly-extending back piece 9. The rear binding-piece S is also pro- Vided with Vertical openings 10, with which a horizontal recess 11 colnmunicates. There are preferably two of the openings 10, and adapted to be passed therethrough are tubular posts 12. These posts are provided at their Serial No. 633,845. [No model.)

lower ends with o-utwardly-extending annular flanges which extend into the outer enlarged 7 of the cover is likewise provided throughout its length with a horizontal recess 17, with which Vertical recesses 18, extending up from the under side of said binding-piece, communicate. The upper ends of rectangular bars 19 are adapted to extend into the Vertical recesses 18, each of said bars provided with parallel horizontal annular end fianges, which have a space therebetween to form an annular recess 20, said annular fianges extending into enlarged portions of the horizontal recess 17. A metallic strip 21 is disposedwithin the horizontal recess 17 and eXtends the length of the binding-piece 16. This strip i s provided with openings 22, which register with the Vertical recesses 18. The bordering ed ges of these openings extend between the annular flanges of the rectangular bars 19 into the annular recesses 20, formed by said flanges. It will be understood that the bars 19 are of exactly the same shape as the tubular posts 12, but are smaller in cross-section than said posts and are so positioned as to extend down to and telescope into said posts.

The rear binding-piece 8 is provided atopposite ends with the upwardly extending plates 23. Upon their in ner sides these plates are formed with recesses 24:, which are adapted to receive and form guideways for arms 25 25, depending from the under side of the upper binding-piece 10. Those plates 23 and the arms 25 fittin g therein not only assist in keeping the two side pieces of the cover in proper relative position with respect to each other, but also prevent edgewise displacement of IOO the leaves between said side pieces of the cover.

Arranged adjacent to the inner side of the back piece 9 and coextensive in length therewith, but of less Vertical height than said back piece, is ablock 26. It will also be noticed that the upwardly-extending plates at the ends of the binding-piece 8, as well as the tubular posts 12, do not extend upwardly fiush with the upper edge of the back piece, but the upper ends of said pieces and posts are flush with the upper edge of the block 26. As the inner edge of the rear binding-piece 16 is coincident with the inner side of the back piece 9, it is evident that this arrangement of the tubular posts, plates 23, and block 26 permit the upper side piece and its binding-strip to be adjusted downwardly below the upper edge of the back piece as the leaves are removed, the adjustment 'downwardly being limited by the upper ends of the posts, end plates, and block. Ordinarily there Will be sufficient leaves between the side pieces of the cover to bring the binding-strip of the upper side piece flush with the 'upper edge of the back piece.

The block 26 at a medial point is cut in or recessed, as indicated at 27. lnto the space formed by this recess is fitted a casing 28i vVVithin this casing is disposed a longitudinally-movable looking-bar 29, which at one end is provided with a series of teeth. The

lower edge of this bar is provided medially with a recess 30, and said lower edge is supported upon led-ges or flanges 31 31'. The u pper edge of the bar is provided with an upwardlyextending lug 32. Between the bar and the face of the recess of block 26 is disposed a pivoted dog 33. The upper edge of this dog extends slightly above the corresponding edge of the longitudinally-movable bar and is provided with a forwardly-extending lug 34, which is adjacent to the. upwardlyextending lug 32 of the bar. The free end of the dog is normally held down by means of a spring 35, pressing upon the upper edge of said dog. Secured to and extending down from the rear binding-piece 16 is a toothed plate 36, the teeth being arranged on the edge thereof adjacent to the `toothed end of the longitudinally-moving bar. This plateis also provided with a vertically-elongated slot 37, into which a pin 38, eXtendin g from the block 26, passes. The back piece 9 of the cover is provided with a keyhole 39, which hole eX- tends through the block 26, so that a key inserted through the keyhole will enter the casing 28 of the looking mechanism in position to operate said looking mechanism.

The peripheral edges of the upper annular fianges at the lower ends of the tubular posts 12 are cut away for a limited distance to form the Shoulders 40 40. Adjacent to these'cutaway portons are lugs 41 41, which when the tubular posts are turned are adapted to contact with either of the shoulders 40 in order to limit the extent of the turning of said posts.

The Shoulders 40 are such distance apart as Will permit a quarter-turn to be given to the annu'lar fianges.

The leaves 42, which are inserted between the side pieces of the cover, are as usual provided with a hinge 43, of linen or muslin, pasted to the rearedge of the leaf and having a rectangular reinforcing-strip 44 on the rear edge of the hin ge. This rectangular reinforcing-strip is provided with the openings 45 45, from which lead straight openings'or slots 46 46, extending to the rear edge of said reinforcing-strip. The openings 45 are so positioned on the reinforcing-strip as when the leaves are inserted in place between the side pieces of the cover' that said openings will register with the upwardly-extendin g tubular.

posts 12.

It will be understood that any desirable form of mechanism may be employed for lockin g the sides of the cover, although that herein shown and described will perhaps be found best adapted for the purpose. In order to lock the side pieces of the cover, all that is necessary to do is to insert a key., such as 47, through the keyhole 39. turned so that the ward 48 thereof will extend up in the recess 30 of the longitudinallymoving bar and act against the lower edge of the pivoted dog. VVith the continued turning of the key the said pivoted dog is turned on its pivot against the downward pressure of the spring until the forwardly-extending lug 34 of said dog is raised above the upwardly-extending lug 32 of the bar. This permits said bar to be inoved longitudinally the required distance to cause the teeth thereof to engage with the teeth of the plate 36,

. and after the key has been turned so that the ward thereof is again out of the recess of the longitudinally-moving bar the dog is free to again turn downwardly on its pivot, and the forwardly-extending lug of said dog is then adjacent to the opposite side of the upwardlyextending lug of the movable bar, so that said bar is locked in'firm engagementwith the toothed plate. It is obvious that in order to unlock the side pieces of the cover, so that the upper side piece can be raised or lowered, all that is necessary is to insert the key and turn the same in the opposite direction.

This key is then v IOO IIC

IIS

This will have the effect of again raising the dog, so as to bring its lug out of engagement with the lug of the bar and permit the movement of the bar in the opposite direction to disengage its teeth from the teeth of the plate 36, as clearly shown in Fig.l 2.

To remove or insert a leaf all that is necessary is to unlock the binder in the manner pointed out. The squared end 49 of the key 48 is then inserted in one of the vertical'openings lO of the rear binding-piece S to engage the lower end of the tubular post.`- By turnin g this tubular post to the extent it is adapted to be turned-viz., one-quarter of a turn'- the greatest width of the tubular post, which in Fig. 4 is shown transverse of the openings IZO o of the lcavcs, is brought to a position at right angles toV the position shown in said figure-that is, so that its greatest width will be in line with the straight slot 4G of the leaves. rl`he other tubular post is then adjusted in like manner. It will be obvious that either additional leaves may be now readily inserted in place or leaves removed from between the side pieces of the binder, and when it is again desired to secure the leaves in place all that is necessary is to turn the tubular posts back to the position illustrated in Fig. 4, which effectually prevents the leaves from being withdrawn, as the greatest widths of the tubular posts are now transverse to the straight slots 46, and said greatest widths of the tubular posts are greater than the widths of said straight slots.
