C. A. CHARBENEAU BOOKMARKER Filed Sept. 25, 1931 iNVENTOR Clarence A C/Zdrbefleczu Patented Jan. 24, 1933 UNITED STATES CLARENCE A. OHARBENEAU, OF MOUNT CLEMENS, MICHIGAN IBOOKMARKER Application filed September 25, 1931. Serial No. 565,130.

This invention relates to bookmarks, and particularly to bookmarks comprising a pl'u-- rality of markers insertable at selective places in a book, held normally in place by a common means and readily removable individually.

An object of the invention isto provide a plurality of markers consisting of elongated strips. of thinflexible sheet material adapted to be positioned between the leaves of'a book,

projecting beyond the top and bottom edges of said leaves, and to form the end portions of said strips with hooks, such as will permit quick and easy attachment of the. strips to,

p and their removal from, a suitable cord or cords extending from cover to cover across'the top and bottom edges of the book.

Another object is to provide a pair of less flexible supporting strips of sheet material,

attachable to the covers ofa book, preferably 39 upon the inner faces of said covers, and to form said strips with stamped-out projections for retaining and properly positioning a cord, or cords, to hold said marker strips in 7 place.

A further object is to form said cover-engaging pair of strips with stamped-out projections adapting said strips to be quickly and easily secured to or removed from the covers.

Still another object is to form one of said pair of supporting strips with a pair of stamped-out projections for quick detachable engagement by the ends of a cord to which the marker strips are attachable.

These and various other objects the invention attains by the construction hereinafter described, and illustrated in the accompanyingdrawing, wherein: f

Fig. 1 is a perspective view of-a' book, showing the herein-disclosed bookmark in use.

' Fig. 2 is another view of said book and bookmark, looking edgewise at the leaves, and showing the covers bent to extend oppositely from and transversely to the leaves, the outer portions'of said coversbeing broken away.

Fig. 8 is an elevational view of the book and book'mark, with the leaves and one of the covers parallel and the other transverse to the plane of the drawing, and the leaves positioned against that cover which parallels the plane of the drawing.

Fig. tie a cross sectional view, taken on the line 4& of Fig. 2, showing an end portion of one of a pair of strips by which the marker is attachable to the covers of a book.

In these views, the reference characters 1 and 2 designate respectively the leaves and the covers of a book.

Secured to the covers 2 upon their inner faces, and extending from top to bottom of said covers, is a pair of elongated strips 3 and 41-, formed of thin sheet material, preferably metal. Each of'said strips is formed upon its upper and lower end portions with a pair of struck-out tongues 5, preferably triangular, projecting toward each other at a slight divergence to the body of the strip, said tongues being adapted to overlap and frictionally grip the top and bottom edge portions of the covers to hold said strips firmly in proper place against the book back, as best appears in Fig. 1. Said strips 3 and 4t terminally project slightly above and below the book for engagement by a flexible elastic cord 6, extending across the book top and bottom to connect said strips, and further extending 7 lengthwise of said strips, its ends being secured to the strip 4 as indicated at 7, preferably by attaching said ends to a pair of triangular tongues 8 struck out of the central portion of said strip 4 and projecting toward each other.

To adapt the cord 6 to quick-detachably engage the projecting ends of the strips 3 and 4, it is preferred to form each of said ends with a keeper. consisting of a small struck-out tongue 9. The tongues 9 project transversely of the strips 3 and 4 toward the front edges of the covers, as best appears in Fig. 2. Each of said tongues is so angularly bent as to diverge from substantially its mid point to its ends, thus forming a keeper space having a flaring entrance portion to readily admit the cord, and having a retaining portion affording free sliding of the cord, while prohibiting accidental escape of the cord. The keeper tongues 9 are adequately resilient to yield freely away from the strips 3 and 4 responsive to an entering. or removal stress on the cord. v

, Between the book leaves, at any desired points, are engaged a series of elongated freely flexible marker strips 10 preferably of transparent material, such as celluloid. Said strips extend from top to bottom of the book, terminally projecting beyond the leaves similarly to the strips 3 and 4. The

upper ends of each marker strip are formed with elongated slots 11, each opening in a longitudinal edge of the corresponding 10 strip and extending to the longitudinal cen-' tral axis of the strip, and projecting along said axis toward the adjacent strip extremity, terminating some distance short of said extremity. The entrance portions of the slots 11 are relatively wide and merge with a gradual curvature into the rectilinear main length of said slots. v t

The lower ends of the strips 10 are each formed with a relatively short slot 12 having a reduced closed end portion projecting downwardly alongthe central longitudinal axis of the strip and having a relatively wide entrance portion openingin the edge of the strip'opposite to that broken by the mouth of the slot 11, the. mouth portion and closed end portions of the slots 12 merging into each other with a gradual curvature.

Each of the described markers comprises, additionally to the strip 10, an arm 13 rigidly stLsecured at one of its ends to the strip 10, and projecting from the latter in a transverse relation thereto, its otherend portion projecting slightly from between the leaves of the book and carrying a suitable reference 3 5..number. Preferably, the arms 13 are formed similarly to the strips 10, of transparent sheet material such as celluloid.

In the use of the described marker, the

metal strips 3 and 4 are initially engaged has described with the book covers, preferably in proximity to the book back, and the cord 6 is then slipped beneath the keeper tongues 9 extending substantially the full length of' the strip 3, and extending upon the strip4" -from the tongues 9 to the tongues 8, being tied or otherwise fastened to the latter.

Any desired number of the marker strips lO'are then insertcd one at a time between the book leaves at'the points to be marked,

5o their upper and'lower ends being successively engaged with the top and bottom spansof e the cord 6. I The wide entrance portions of theslots 11 and l2permit the extremities of the marker strips to be readily hooked upon said cord spans, and the considerable longitudinal extent of the slots 11 insures retention of the upper cord span in said slots during engagement of the lower span in the slots 12. The cord 6 is preferably. sufiiciently fact that marker ,stripswhen once engaged with the cord 6 are quite securely held by thelatter, so that concurrent use of a large number of the markers creates no tendency toward release of the markers.

Furthermore, the described provisionfor 1 engaging the marker strips with the cord and for attaching the latter to the supporting strips 3 and 4 minimizes the time necessary for these operations, as well as avoiding ac cidental disengagement of the parts.

While it is apparent that the illustrated embodiment of this invention is well calcu lated to adequately fulfill the objects and 'advantages primarily stated, it is to be understood that the invention is susceptible to va riation, modification and change within the spirit and scope of the subjoined claims.
