' Applicatio August 8, 1941, set-e1 No..-4 6,0.65 '5' Clain1's'. f (01. 1'1fc -1 19)' -My invention relates-torbookmarkers. 7

One of the objects of my invention is to provide.

a' bookmarker in; which the marker elementds transparent so that ;there will be .no-difiiculty in reading the printed page. under :the marker element. Furthen t-he marker e'lement is so shaped that u-pen turning a-page' the travel of the page on the sloping engaging edge of the marker willpausei-the-marker tobe" ;,raise dto e t e passa e o zin pa er a d th r aft r a n pla e:asaimm r ethe n w pa e. In markers which accomplishthe above indicated purposes, simplicity of manufacture and assembly are desirable features, since the markers are made in large quantities. marker element'itself of flexible resilient material and" providing -the cutaway portion, the marker and slot through which the support passes can be deformed so 'as to permit the insertion of the head of the support for. the marker. Upon release of the marker element, it will,

because of its resilient nature, spring back into operative position. A further form of device is one in which the support carrying the head is provided with a cutaway portion, the support" being also made'of flexible resilient material which will permit the deformation of the support By making the so that the headmay be inserted through the 1 slot in the marker element.

In the drawing:

Fig. 1 is a perspective View ofmy complete bookmarker construction.

Fig. 2 is a View in side elevation of the bookmarker' showing it'in place in the book, the raised position of the marker element being indicated in dotted lines.

Fig. 3 is 'a perspective view of a book with the marker in place and a page of the book in the process of being turned.

Fig. 4 is a perspective View of a book with the marker in place after the page has been turned.

Fig. 5 is a perspective view of a modified form of my marker in which the support is provided with a cutaway portion permitting tion during assembly.

Referring to the drawing, Figs. 1 to 4, I have shown a bcokmarker which is adapted to be made of flexible resilient material, preferably transparent, such as some of the transparent flexible resilient resins which are designated under the general term plastics. I have shown an integral body supportand head in which the numeral I indicates a body which is adapted to fit in and lie between the pages of a book, as more clearly illustrated in Fig. 4 in which the its deformabody [is shown idottedplines between the pages of a book 2.; The' body ,iI is provided with a cutaway portion 3 providing aton et I which is adapted to fit over the pagepf, 3 .13001; so as toholdgthelbody I securelyginplaceyx In using. the'markenthe body l .isplaced at a point .sufiiciently' far ahead of :the page; being: read to hold the body I securely "in place,- andthe tongue 4 is sl-i'pped'overa pa e; orpages :to securely hold the body Igin positionduring use.

' The bodYI-is struck up at substantially right angles to form a support portion 5 having a cutaway portion. 6. on either side thereof :over. which is adapted to slidena roove ;I formedinamarker 8 which is provided with sloping edges 9 and I0. The sloping edge I0 is adapted to contact the edge II of a page I2 which, when raised as indicated in Fig. 3, causes the marker element to rise and slide upward on the support 5.

The support 5 is provided with a head I3 sufficiently large to .prevent the head I3 from sliding through the slot 1 formed in the marker 8. This permits the marker 8 toslide up and down on the reduced portion 6 of the support 5, but prevents the marker 8 from becoming disen-' gaged from its sliding position on the support 5.

In assembly, the flexible, resilient, transparent marker 8 is deformed by pressure along the lines of a slot I4 having an enlarged end I5 formed in the marker. I5 lie adjacent and substantially at. right angles to the slot 7. By deformation of the marker 8,

the head I 3 can be slipped through the slot 1, and

the parts then spring back into the position shown in Fig. l by reason of the resilience of the parts. During the assembly, the support 5 can also be deformed if necessary to permit the slot I to be slipped over the head I3 of the support 5.

In another form of my device, the marker 3 may not necessarily be constructed with the slot I4 and it'senlargedend I5 thereof. This is not prohibited. However, in order to assemble the parts. I provide the support 5 with a cut out portion I6 as illustrated in Fig. 5. By pressing togather the two sides of the support 5, as indicated by dotted lines in Fig. 5, the slot I of the marker 8 may be slipped over the head I3 of the support 5. Then support 5' springs back into the position shown in solid lines in Fig. 5 and the device is completely assembled for use. p

I desire that my inventionbe limited only by the scope of the appended claims and the showingof the prior art.

I claim:

1. A book marker for a book having pages, said This slot I4 and enlarged end. I

marker comprising a body portion adapted to be held between the pages of the book, a vertical support carried by the body, a cut away portion along each edge of the vertical support, a flexible resilient marker having a slot therein whereby the marker can slide in the cut away portions in the support, an elongated cut in the marker that communicates with and is at right angles to the slot so that in flexing a portion of the marker adjacent the elongated cut the marker can be positioned in the cut away portion of the support. 7 2. A book marker for a book having pages, said marker comprising a body portion adapted to be held between the pages of the book, a vertical support carried by the body, a cut away portion along each edge of the vertical support, a flexible 4. A book marker for a book having pages, said marker comprising a body adapted to be held between the pages of the book, a flexible resilient J in the cut away portions.

resilient transparent slide marker having a slot therein whereby the marker can slide in the cut 1 awayportions in the support, an elongated cut 1 in the marker that communicates with and is at right angles to the slotso that in flexing a portion of the marker adjacent the elongated cut the marker can be positioned in the cut away portion of the support. J

3. A book marker for a book having pages, said marker comprising a'bodyadapted to be held betweenthe pages of the book, a flexible resilient vertical support carried'by thebody, a cut away portion along each edge of the-vertical support, a

slidable marker having a'. slot whereby the marker canslide in the cut away portions, and a cut in the vertical support whereby the vertical support can bedeformed to permit the slot in the marker to be fitted in the cut away portions.

5. A book marker for a book having pages, said marker comprising a body for insertion between pages of the book, aflexible resilient support element carried by one end of the body and extending perpendicularly to the plane of the body and the-pages of the'book, a slidable flexible marker element having a slotformed therein adjacent one end thereof-said slot being of a length corresponding-to the width of the support element ments.

and having said support element extending therethru; and a head-on the free end of said 'support element of a width greater than the length of said slot to prevent undesired removal of the slidable marker element from said support element, at least one of said support and slidable marker elements having a slit portion to render that element having a slit portion deformable to provide for assembly andseparation of said elef LEON KARDORFF.
