`UNI'IED 'sTATEsf' PATENT OFFICE Leslie A. Minton, Portland, oreg.

Application May 2, 1945, Serial No. 591,539

The general aim of my invention is to provide a carrier by which ar book mark, blotter, calendar, pad of note paper, tables, scales, protractor, any type of memoranda, advertising 1 Claim. (CL281-42) matter, and/or for holding any floating element or auxiliary sheets with a clearance o r opening sufciently large to permit the leaves of the book to be turned through said openings.

This invention relates to an improved leaf carrier or turner and a book mark, and one of its objects is to provide means for positively engaging a selected leaf of a book, and a frame on which the leaf turner and book mark is supported, which can be assembled on a loose leaf or split ring book.

Another object of the invention is to provide a two piece assembly for supporting the leaf turner and marker, so constructed that it may be readily combined with a standard ring or other type of book.

With the above and other objects in View the invention comprises certain new and useful constructions, combinations, and arrangements of parts, clearly described in the following specification, and fully illustrated in the accompanying drawings, in which:

Fig. l is a plan view of one form of the invention, showing parts of the book in dotted lines, and parts of the device in section.

Fig. 2 is a similar view, showing only the leaf turner and book mark, with a part shown in section.

Fig. 3 is an end elevation, showing the book in full lines.

Fig. 4 is a detail, fragmentary, end view of the wire holding frame.

Fig. 5 is an end view of a book, equipped with the attachment, showing the book closed.

Fig. 6 is a plan view of another form oi. the invention, certain parts being shown in longitudinal section, showing shaft sections in coupled relation. `1

Fig. 7 is a similar view, showing the shaft sections in uncoupled position.

Fig. 8 is a detail end view.

Fig. 9 is a detail transverse sectional view, taken on line 9-9 of Fig. 6, looking in the direction of the arrows.

Fig. 10 is a perspective view of a book closed, showing the book mark in position thereon.

Referring to the accompanying drawings, which illustrate the practical embodiment of the invention, 5 designates a thin metal, plastic, libre or material sheet, which is formed with an edg roll 6 on one longitudinal edge thereof.

The sheet 5 is supported on a wire frame T, which includes side bars 8 and 9, each of which is 4formed with a side arm or leg I0 on its inner side and a similar side arm Il on its outer'side. The side-arms or legs Il are slidably inserted in the ends of the edge roll E and the inner side arms or legs I are slidably inserted in the tube I2, which is formed with a small bore. One of the end side bars or frames may be partially withdrawn from pivotal engagement with the ends of the sheet roll 6, and the sliding connection of the inner side arms or legs I3 is adapted to permit this. This sliding connection also permits one of the side bars 8 or 9 to be entirely detached from the tube I2, so that the tube may be then passed through the split rings of a loose leaf book.

The wire frame may be constructed in one piece, as shown in Fig. 2, and in this case is provided with a continuous inner bar I3, and with integral side bars I4 and I5, which are connected to the inner bar by the closed loops I6 and I1, as shown in Fig. 4. 'Ihe side bars I4 and I5 are formed with terminal trunnions Ma and i511, which engage the ends of the edge roll I8 carried by the sheet turner and marker plate I9. The inner bar I3 is adapted to extend through the split book rings 20, of the book 2l, shown in Fig. 5.

In Figs. 6 to 9, inclusive, I show a modied form of the invention, wherein an outer tube 30 is provided in which an inner tube 3l is snugly fitted. The wall of this inner tube is formed with a notch or opening 3m, located between the ends thereof, and completely enclosed and concealed by the outer tube 30.

In one end of the inner tube 3I the inner end 32 of the end bar 33 is secured, which is spaced longitudinally from the keeper notch 3Ia. This keeper notch is engaged by the inner end 34 of the side bar 35, and this inner end 34 is formed with a terminal hook or latch element 34a, which is adapted to snap into the keeper notch Sla, and for this purpose the inner end or bar 34 is reduced longitudinally at 34h, so that the terminal latch will have a spring action against the notch 3Ia.

The side bar 33 is formed with a trunnion 33a on its outer end and the side bar 35 is formed with a trunnion 35a on its outer end. These trunnions are adapted to engage the edge roll of the leaf turning and book marking sheet.

On the outer tube 30 a thin connector blade or bar 36 is supported by the eye hooks 36a and 36D, which are formed from the stock of the blade or arm 36, and which may be sprung over the ends of the tube 30. The blade or arm 36 is placed between leaves of the book, and the side bars 33 and 35 are disposed against the upper and lower ends of the book, with the page turning sheet 31 supported on the terminal trunnions 33a and 35a, in the manner previously explained.

In Fig. '7 a modied arrangement of the coupling blade or arm 36 is shown, wherein this blade is formed with holes -36 to receivebook hooks or rings.

It is seen that when the page turning sheet is properly arranged between opposing leaves of a:

book, that the book may be-quieklyand @Gsurately opened at the place marked by the position of the leaf turner sheet.

The invention will be found partieularly useful in connection with the quick opening of account and record books, and also of books on art,-science, history and literature. `When used the book mark will vremain in4 selected position, until it ziszre- Aad'jllsfied Orishifted to a ldifferent, position.

Itis understood that various. cbangesinrthe details '-of. .Qonstruetom and therzombination .endarrangement .may bemade. andalsony and Y:all 4materials available for theproduction of the Adevicegmay be employed, within the scope o i the invention as defined by the claim hereof.

Having described my invention, I claim as new:

A book marker and leaf turner comprising a tubular cross bar having an internal latching element, a side bar having an angular end secured REFERENCES CITED The'following references are of record in the i` file Tof this patent:
