INVENTOR W/LL/AM M CHAPMAN ATTORNEY United States Patent 3,209,648 TELEPHONE BOOK MARK WITH MAGNIFYING LENS William M. Chapman, 653 The Queensway, Toronto 18, Ontario, Canada Filed May 11, 1962, Ser. No. 193,998 3 Claims. (CI. 88-39) This invention relates to a novel book mark including magnifying means adapting the book mark particularly for use with a telephone directory or the like where a line of names, for example, is to be scanned.

A primary object of the invention is to provide a linear alignment edge on a book mark including magnifying means having a co-linear edge in alignment with that of the book mark whereby a line of numbers or namesis successively magnified as the linear edge is traced therealong.

Other objects and the nature and advantages of the invention will become apparent from a consideration of the following description, taken in conjunction with the accompanying drawing, wherein several embodiments of the exemplary invention are disclosed.

In the drawings:

FIGURE 1 is a perspective view illustrating the manner in which one embodiment of the novel book mark is used;

FIGURE 2 is a side elevation of FIGURE 1 illustrating diagrammatically the line-of-sight of a user directed toward the novel book mark;

FIGURE 3 is an enlarged, fragmentary top plan view of the book mark of FIGURES 1 and 2; 1

FIGURE 4 is a further enlarged section taken on line 44 of FIGURE 3;

FIGURE 5 is an enlarged fragmentary perspective view of the lens element of the novel book mark;

FIGURE 6 is a section taken on line 6-6 of FIG- URE 3;

FIGURE 7 is an enlarged fragmentary view of the planar body member of the novel book mark;

FIGURE 8 is a view similar to FIGURE 2 showing another embodiment of lens element used in the novel book mark; and

FIGURE 9 is an exploded, enlarged perspective view, showing the lens element of FIGURE 8 and the manner in which it co-operates with the body member of the book mark.

Referring to the drawings in detail, a telephone book is indicated generally at B and includes a typical page P including a vertical line of names N including a line N which is magnified. The novel book mark 10, although illustrated in use with a page of a telephone directory, obviously has other uses, for example, with a line of numerals in actuary charts.

The novel book mark 10 is grasped in the users hand H and will be successively moved vertically past the line of names N and assuming line N' is the one which a user is searching, see FIGURES 1 and 2, the users eye E will be directed toward the lower linear edge 12 of the book marks 10 and 10', and the name N being observed will be magnified by a lens element indicated generally at 14 and 14 in FIGURESl-7, and 8 and 9, respectively.

Considering the drawings in detail, the book marks 10 and 10' include in the exemplary embodiments a substantially rectangular, planar body member 16 of any suitable material, i.e., paperboard, plastic, etc., which may conveniently include a nail-receiving aperture 18, portion 20 for writing down often-used phone numbers, an area 22 for advertising indicia and a calendar 24. Although the body member 16 is disclosed a rectangle, other shapes are contemplated to be within the scope of the invention,

3,209,648 Patented Oct. 5, 1965 the primary requisite being that they include at least one linear edge 12.

The body member 16 includes intermediately of the edge 12 an inwardly extending rectangular notch portion 26. Disposed on opposite sides of the notch portion 26 are transverse apertures 28 for receiving fastening rivets 30, for example, to mount the magnifying elements 14 and 14' on the body member 16. Other means, not shown, may be utilized to mount the magnifying elements in an operative position, a suitable adhesive, for example.

Considering FIGURES 1-7, the lens element 14 is elongated and is manufactured from any suitable material, glass, plastic, etc. The element 14 includes opposed convex sides 32 and 34 which respectively intersect angular faces 36 and 38 which intersect in a linear edge portion 40 which is co-linear with the edge portion 12 of the body member 16; see FIGURES 1-4. Note in FIGURES 1 and 2 the co-linear edges 12 and 40 will be disposed beneath the line N being observed and the name, etc. will be magnified.

The lens element 14 includes at opposite ends thinnedout, undercut portions including a planar surface 44 juxtaposed on the outer surface of the body member 16 when the element 14 is disposed within the notch 26. The portions 42 include a transverse aperture 46 alignable with the apertures 28 and through which the rivets 30 extend.

When using the embodiment of FIGURES 1-7, the body member 16 is manually supported in angular relation to the page P, see FIGURES 1 and 2, however, in FIGURES 8 and 9, the lens element 14' aids to support the book mark in angular relation.

The lens element 14' will be received in the notch 26 of the body member 16 and will be mounted by the rivets 30 in the manner previously described. The lens element 14' includes a planar forward face 34 including a lower linear edge portion 40' intersected by a lower flat face 36' which includes the edge portion 40' and the face 36' is normal to the planar face 34'. The element 14' includes a convex upper surface 46 and undercut portions 42' at opposite ends which include an angular surface 44' extending away from the linear edge portion 40' and substantially intersects this linear edge portion 40'.

The angular surfaces 44' are juxtaposed on the outer surface of the body member 16 as in the previously described embodiment, and the body member 16 will extend angularly from the linear edge portion 40' to facilitate sliding of the lens element 14' and co-linear edges 12 and 40 along the row of names N until aligned beneath the name N.

It is to be understood that the forms of the exemplary invention shown and described are to betaken as preferred examples only, and various changes made as do not depart from the spirit of the invention or the scope of the appended claims.

What I claim is:

1. A book mark comprising a planar body member including at an outer margin at least one linear edge for alignment with and tracing along a row of indicia such as that found in a telephone directory or the like, and a magnifying lens element having an upper convex surface and secured on said planar body and extending transversely of the plane of said body member, said body member including a notch portion opening into said linear edge portion, said lens element including a portion corresponding to the shape of said notch portion and transversely filling said notch portion, said lens element including a linear edge in co-linear relation to said linear edge of said body memher, said lens element having a pair of undercut, notch lens element includes a lower fiat surface intersecting the linear edge of said planar body member and in angular relation to the body member, said undercut notch portions being at angular relation to said lower fiat surface and terminating at the linear edge of said lens element.

3. The structure as claimed in claim 1 in which said lens element includes a pair of angularly related surfaces intersecting at said linear edge of said lens element, said the linear edge of said lens element.
