LOOSE-LEAF BINDER.
Specification of Letters latent.
Application filed November 14, 1918. Serial No. 262,513.
in which corres onding numerals of reference in the di erent figures indicate like arts.
The object of my invention is to provide a simple, cheap and effective locking device for loose-leaf binders, which shall be so constructed as to insure its ready and easy operation regardless of rust or other srmllar causes whlch tend'to afl ect metal surfaces when in continuous use under varying atmospheric conditions. To this end, m invention consists in the combination 0 elements hereinafter more particularly described and definitely pointed out in the claims.
In the drawings,
Figure 1, is an end view of a binder embodying the features of my invention,
Fig. 2, is a sectional view of a portlon thereof, taken upon the line 2- 2, Fig. .1,
viewed in the directionof the arrows there I shown, and
.cover supports of any approved form to which lids 2, are hinged bymeans of flexible covering material. Said supports are rigidly attached in any approved way to counterpart binding 'members generally designated by 3 and 4. I Said bind ng members are formed from sheet metal and consist of parts 5 and 6, extending throughout the length of the binder and hinged to each other at 7. Integral with said members 5 and 6 and bent in opposite directions at substantially right anglesthereto, are portions or members 8 and 9 having flanges 10 and 11 respectively, formed thereon, which flanges are intended to be substantially parallel to I each other when the binder is closed,the
cover- supports 1, 1 being rigidly attached thereto, as are also plates 12 and 13, which serve as supports for the usual binder prongs 14. I
A locking-bar 15, of a length preferably correspondin substantially to that of the binding mem ers, is located outside of and parallel to the member 9 and adjacent to the member 6. Said bar is formed from sheetmetal and is concavo-convex in cross-section.
Patented Nov. 4, 1919.
This construction not only imparts rigidity I to' the bar but provides what may be termed longitudinal knife-edge bearings 16, 17, Fig. 3, against the outer 'face of the part 9. Cli s, generally designated by 18, are attac ed to the plate 9 by means of rivets 19' and serve to hold the bar 15 in place while permittin it to slide longitudinally. It will e noted t at said clips are so formed as that each will contact with the bar' at two portions only, viz: the outer edge of the bar and upon a longitudinal line upon the outer convex face thereof, as shown at 20. From the description given, it will be ap arent that an accumulation of rust upon thear as would be likely to occur in ordinary use, would not besufiicient to prevent its fre longitudinal movement.
- A series of registering slots 21, 22, Fig. 2,
is formed in the members 5 and 6, for the 6 an the other to the bar 15, thus enablin it to yieldingly hold said bar in a locke 1 position. A thumb-piece 25, formed upon the outer end of the bar, enables the latter to be pushed inwardlyfor the purpose of unlooking it. Practice bound under the most humid atmospheric conditions.
Having thus described my invention, I claim 1. The combination with the binding members of a loose-leaf binder, of a longitudinally arranged, spring-controlled lock- I ing bar slidably mounted upon one of said members, sald locking bar being concavoconvex in cross section-with its edges only in contact with said member, and having do I has demonstrated that the 10st. ing member described will not become rust- I terpart of the member to which said bar is attached, guiding means for engaging the convex surface of said locking bar and means for normally holding said bar in a locked position.
3. The combination withthe hinged binding-members of a loose-leaf binder, of a longitudinally-disposed slidable locking-bar mounted upon one of said members, said bar being concavo-convex in cross section with its concave side facing the member to which it is secured, guide members therefor, laterally extended detents formed upon said locking-bar and arranged to pass through slots formed in said binding member and its counterpart for locking said members together and a spring for normally holding said bar in a locking position.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses, this twelfth day of November, 1918.
ERIK L. KRAG.
