PAGE-INDICATOR.

SPECIFICATION forming part of Letters Patent No. 680,363, dated August 13, 1901.

Application filed December 1, 1900. Serial No. 38,852. No model.)

To all whom, it mag/concern:

Be it known that I, ROBERT SCOTT, a citizen of the United States, residing at North Yakima, in the county of Yakima, State of Washington, have invented certain new and useful Improvements in Page-Indicators; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to indicators in general, and more particularly to those designed to be used in connection with books, and has for its object to provide a device of this natu re which will retain the book in an open position, which will keep the column heading or title directly above the line to be written upon, and which will be cheap of manufacture and simple of construct-ion.

In the drawings forminga part of this specification, in which like characters of reference indicate similar parts in the several views, Figure 1 is a top plan view of a book provided with my invention. Fig. 2 is a section on line 2 2 of Fig. 1, and Fig. 3 is a section on line 3 3 of Fig. 1.

In the construction of a column-indicator in accordance with my invention I provide two plates 5, preferably of sheet metal, which are substantially in the shape of a truncated rightangle triangle, and these plates are hingedly connected at their broad ends. As shown in Fig. 2, each of the plates 5 is curved downwardly at the ends I) and b to conform to the shape of the book.

Secured to the upper faces of plates 5 are strips 6 of lead or other heavy metal, which are substantially semicircular in cross-section, the object of these strips being to add the necessary weight to the device to cause the pages of the book to lie fiat. Each of these strips 6 is provided along its edge 6 with a slit 7, into which is inserted a second metal plate 8, as shown in Fig. 3 of the drawings. The lower face 8 of the plate 8 is brought into contact with the upper face of plate 5 by bein g curved downwardly over the rounded surface 6 of the strip 6, the two plates forming a spring-clip, into which may be inserted a strip of paper 12, on which the column-head ings are written or printed. 'i

Secured to the under face of each of the plates 5 are clips 10, which hold astrip of Not ting-paper 20 of the same size and shape as the plate itself, and this strip of blotting-pa per will absorb the ink as the device is moved downwardly over the portion of the page already written upon.

In practice the indicator is placed upon an open book, the hinge resting in the fold of the pages and the downwardly-turned ends I) lying against the edges thereof. The strip of paper 12 is divided into spaces of the same width as the columns of the book, and when the device is in operative position these spaces should form a part of the columns, as shown in the drawings. After one line of the book is written upon the indicator is moved downwardly to cover this line, and the edge of strip 12 should then be on a line with the upper boundary of the space next to be written upon. In this manner the column-headings are kept at all times directly under the eye of the writer, obviating the necessity of glancing at the top of the page.

YVhat is claimed is 1. A device of the class described comprising hinged plates having clips at the front and rear edges on the under sides thereof adapted to receive a blotter, and clips upon the upper faces of the plates at the front edges thereof to receive slips of headings.

2. A device of the class described comprising weighted hinged plates, said plates having each a blotter secured to its under side and having clips on its upper side for engagement with heading-slips.

3. A device of the class described comprising hinged plates, a weight secured to the upper face of each plate, spring-clips engaged in the weights and disposed to exert clamping actions against the plates, and means for holding blotters to the under sides of the plates.

In testimony whereof I hereunto sign my name, in the presence of two subscribing wit- 5 nesses, on the 16th day of October, 1900.

ROBERT SCOTT.
