Application June 23, 1952, Serial No. 295,049

1 Claim. (Cl. 116-119) This relates to a book marker, and more particularly to a book marker which can be easily inserted into any page of a book and which is adjustable to fit various size books.

Most people generally use rubber bands or the like to indicate the desired page and line in a book. Various mechanical marking devices have been developed, but all of these have been either too complicated in structure or not accurate enough for the purpose.

It is, therefore, one object of this invention to provide a book marker which will clearly and accurately indicate the desired page and line in a book or ledger.

Another object of this invention is to provide a book marker which is simple in construction and contains relatively few parts.

Another object of this invention is to provide a book marker which is adjustable to fit any size book or ledger.

Other objects of this invention are to provide an improved device of the character described that is easily and economically produced, which is sturdy in construction, and which is highly efficient in operation.

With the above and related objects in view, this invention consists in the details of construction and combination of parts, as will be more fully understood from the following description when read in conjunction with the accompanying drawings in which:

Fig. 1 is a front view of a book showing the marker in place.

Fig. 2 is a perspective view of the marker.

Fig. 3 is a perspective view of a portion of the marker.

Fig. 4 shows the page indicator portion of the marker in fully retracted position in full line and in expanded position in dotted outline.

Fig. 5 shows the line marking element.

Fig. 6 shows a perspective view of a portion of the marker which is complementary to the portion shown in Fig. 3.

Referring now in greater detail to the drawings wherein similar reference characters refer to similar parts, there is shown a book marker comprising a page marker member A and a line marker B. The member A comprises two telescoping units 10 and 12. The member 10 consists of an elongated channel member 14, which is V-shaped in cross-section, and connected to the member 14 at one end thereof is a flat V-shaped plate 16. An elongated tubular element 18 is connected at one end to the plate 16 and extends parallel to the channel member 14.

The unit 12 is similar to the unit 10 in that it consists of a V-shaped channel member 20 having a fiat V-shaped plate 22 at one end and an elongated rod member 24 extending parallel to member 20, the member 24 being connected to plate 22 at one end. The member 24 is, however, not necessarily tubular, but may be either a solid or a tubular rod. Its diameter, however, is less than the interior diameter of member 18 since member 24 is adapted to telescope into member 18. Similarly, the V-shaped member 20 is of slightly less width than member 14 and is adapted to telescope therein. The member 14 is provided with rolled edges or flanges 26 which are adapted to slidably receive the edges of the member 20 therein.

The unit 12 is telescoped into the unit 10 to form the page marker A and the longitudinal size of member A ice may vary from the compressed position shown in full line in Fig. 4 to the fully extended position shown in dotted outline in the same Fig. 4.

The line marker B consists of two relatively movable plates 28 and 30. Plate 28 is provided with a rolled portion 32 at one end and with a pair of rivets 34 on one face. The plate 30 is provided with a centrally positioned slot 36, this slot being adapted to adjustably receive the rivets 34. A spring clamp 38 is connected to the end of the plate 30 by having projecting tabs at the end of the plate peened through holes 40 and is provided with clamp lips 42 on each side of plate 30. A pair of ears or fingers 44 are integral with the clamp and provide finger pieces for opening the clamp against its inherent spring tension.

The line marker B is connected to the page marker A by inserting the rolled portion 32 over either the member 18 or the member 24 before assembling the units 10 and 12. After these units are assembled, the marker B is then free to move along the axis formed by both members 18 and 24.

All the parts of the assembled book marker except the clamp 38 are preferably made of plastic, the clamp being preferably made of spring metal, but may be of resilient plastic. However, the entire device may be made of metal, wood or any other desired material, while the clamp may be formed of resilient plastic, rubber or any other resilient material.

In operation, the book marker is placed in a book 46 by inserting the apex of the V- shaped channel members 10 and 12 into the fold between two adjacent pages 47 and 48 in the manner shown in Fig. 1, with the plates 16 and 22 abutting the edges of the book 46 at either end of the fold, the telescoping page marker having been adjusted so that the plates 16 and 22 just fit over these edges. The line marker B is then slid to the appropriate line on the page and the plate 30 is adjusted relative to the plate 28 so as to fit the width of the page. The clamp 38 is then clamped around the edge of the page to hold the line marker in position. It should be noted that the line marker may be used for either the right or left hand page by merely pivoting it on the axis of the page marker.

Although this invention has been described in considerable detail, such description is intended as being illustrative rather than limiting, since the invention may be variously embodied, and the scope of the invention is to be determined as claimed.

What is claimed as the invention is:

A book marker comprising a page marker and a line marker, said page marker comprising an elongated channel member of a V-shaped cross-section and an elongated bar secured parallel thereto, said line marker com prising an elongated member pivotally and slidably connected to said elongated bar of said page marker and extending substantially perpendicularly thereto, said page marker being adapted to be inserted in the fold between two adjacent pages of a book with the apex of the V fitting snugly in the fold, said elongated channel member and said elongated bar each consisting of a plurality of telescoping members and said line marker consisting of a plurality of plates, at least one plate having a slot therein and at least one plate having rivets thereon, said rivets being adapted to be received in said slot to form a slidable connection between said plates.
