SELF SETTING BOOK MARKER Filed Feb. 5, 1930 Patented Jan. 20, 1931 UNITED; STATES PATENT OFFICE HEBEIR GEORGE HEAZLEWOOD, OF BENDIGO, VICTORIA, AUSTRALIA, ASSIGNOR OIE ONE- FOURTH T HEBER GLEN HEAZLEWOOD AND ONE-BALI TO JOSEPH HENRY HUNT,
BOTH OF BENDIGO, AUSTRALIA l SELF-SETTIN BOOK MARKER 'Application filed February 5, 1930, Serial No. 426,161, and. in Australia October 9,1929.
- An object of this invention is to provide for books, files, and other sheet matter an automatic place marker which contains improvements upon book markers previously known, as I find that merely to use agrip, wire arm, and terminal in combination does not prove successful. It is known that, in"
using an automatic marker, as each sheet is turned, a terminal or pointer on the marker 10, changes position by springing upon a page newly exposed to view. With the present marker the terminal will, if required, also springupon sheets successively. reached during backward sheet turning when the marker is set'with that object. A marker should act effectively on books greatly difiering in thickness, and without damaging the sheets, and the-terminal should require very slight force to raise it. Our marker meets these conditions.
flanged grip-which during use-is located securely against displacement, and which protects from injury a part of the spring arm which connects the grip with the terminal. The protected part is coiled, the coiling ensuring flexibility. Another object of our marker is to provide a projection which can easily be grasped to enable a closed book to be at once opened at the marked place. This projection can be used also to set the terminal in any selected position. :The terminal has when requiredmeans tokeep leaves apart slightly, facilitating opening of a closed book at the place marked.
" My terminal has limbs positioned to secure satisfactory springing from sheet to sheet; its point is somewhat blunt, and is in one form a coil.
40 In this specification, the word book is used for brevity to refer to any series of sheets with which the marker is usable.
The word: cover is used for brevity to refer to the part to which to attach the grip. 4 This partis a back cover, a wrapper, or any It has a" convenient sheet or groupof sheets'of suflicient strength. l r 1 In the accompanying drawings my marker is illustrated, but modifications of details maybe made while retaining matter in any of the claims.
Figure 1 is a perspective view of an open book having a marker, parts of sheets being omltted for clear illustration of the grip. 1
Figure 2 is an elevation of the head of the book, showing a leaf raised as when being turned, the arm and terminal being thereby raised. V

- slope.
a coil E and for the protection of the arm at this part it is located close to one side of the flange; from the coil the arm extends to the other ,side of the flange and obliquely upwards, for example as in Figure 3. There is to be ample flexibility of the arm under the very light upward pressure which may be applied to it by a turning leaf, and such flexibility renders the marker suitable for use on thick books. 1 For these reasons we provide on the arm intermediately of its ends, a coil E or the like. Arm E extends, in the form illustrated, from an extremity E where flange D? holds it, see Figure 3, along the flange outer face to coil E then the arm bends to the flange inner side as in Figure 1, No part restricts sheet movement, or damages sheet edges; and this marker can be applied to books the covers of which do not project above the sheet edges. The terminal is shown integral with the oblique arm, though an attached piece would act. 7
The user locates the terminal where h wishes, that is on the page on which he reads or writes for example. The terminal has limbs F F and a blunt point F which is when desired a coil. Ithas a handle F and an offset or kink F That limb of the terminalwhich is nearest to book edge A extends obliquely relatively thereto, the slope facilitating leaf turning. When in use the terminal contacts with the page at its point F, but it may contact with it to some further extent; thus limb F contacts wholly or in part with the page.
2 Limb F is advantageously made to have a rising slope from the point F, the page surface being in the position shown by C in Figure .9. But in some circumstances, as when many sheets are under the terminal, the stress on it may cause limb F to set more flatly on the page. The limb F in Figure 10 tends to maintain an upward slope by the aid of the coil at F Closing the book would naturally, however, reduce or obliterate said When point F is constituted by a coil or convolution, as in Figures 7 and 10, leaves are held slightly apart by the coil thickness, even when the book is closed. In the absence of the coil or the like the terminal limbs would, under considerable pressure, flatten between pages C and C To enable the user to shift the terminal at will to another page, handle F is shown. To suit use with books of various thicknesses the aforesaid oflset or kink is provided, and
it enables each sheet to be turned easily without sustaining damage to its upper edge. The oflset connects the terminal with the arm,
and allows the terminal limbs to take suitable positions notwithstanding that there may be many or few sheets under the ter minal. A suitable kink or offset extends more transversely to the sheet edges than slighter in the case of Figure 6 than in'the case of Figures 1 and 7.
Assuming that a book is being read, and
that a sheet is raised and turned, this action causes the terminal on the sheet to yieldto. some extent, and it also causes the flexible elongated arm to swing upwardly relatively to the grip, and to swing also away from edges A and as a result the sheet easily glides clear of the terminal which springs lightly down onthe succeeding; sheet 0 In the claims the term anchored is used for brevity to mean attached to any suitable back- I claim p 1.- A page marker having a grip to'be anchored, and a spring arm having oneend attached to the grip and the other end attached to or extended to form a terminal, comprising a pair of returned limbs forming an-angular point, adapted to bear on a page, a project ing shoulder formed in the terminal, connecting same with the spring arm, for the" purpose of holding the returned: limbs off the page and permitting only the angular point of the terminal to bear: against said page.
21A page marker having a terminal, a spring'arm extending therefrom totraverse sheet edges, a flange to traverse sheetedges, the flange being attached to the arm and protecting the adjacent part thereof, and a grip carrying the flange having a returned front plane with an upturned edge adapted to easily engage the book on which it is mounted.
3. A page marker having a grip'and a terminal, a spring arm extending from the ter minal to the grip, and adapted to traverse sheet edges, an outstanding flange on the grip traversing the sheet edges, a convolution in the arm parallel with,.and abovethe flange and a second convolution, on the arm, on the opposite side of the flange.
4. A page marker according to claim 2, with the grip body audits flange extending in planes at'right angles'to each other for holding the spring arm in secure position above/and parallel with the flange, and for gripping the book at its corner.
5. A page marker having a grip,a terminal, an obliquely extending spring arm, connecting the terminal with thearm, an offset extending less obliquely than the'arm,the
terminal at the side nearest the'side 0f the page having a slope extending from'the arm to the terminal point in a direction bearing from said edge.
6. A page marker having a flexible arm carrying a terminal having a blunt angular point, part of the terminal having a slope from said point upwards relatively to the position which is occupied by a marked page.
7. A page marker having a long spring arm, a terminal, a limb on said terminal having an upward elongation to project clear of book edges, and a handle adapted to be used for terminal adjustment,
In Witness whereof I have hereunto signed my name to this specification at Melbourne in the State of Victoria, in Australia, this sixth day of January, 1930.
