Application filed November To all whom it mag concern:

Be it known that I, WILLIAM G. CoRTn you, a citizen of the United States, residing at Oblong, in the county of Crawford and State of Illinois, have invented new and signed primarily for advertising purposes,

In the drawing:

Figure 1 is a perspective View of the invention as used for holding an open .book.

Figure 2 is a perspective view of the invention removed from the book.

Figure 3 is a longitudinal sectional view thereof,

Figure ,4- is a detail plan view of one end of the invention;

The invention comprises a relatively broad, flat strip 5, of suitable material, having graduations 6 inscribed on its front face, and a superposed comparatively narrow strip 7'. The strips and 7 are connected only at their ends by eyelets 8 or similar fastening means, one of the strips,

' overhanging the sides of the slot. The strip 7 is flexible, so vthatit may be opened up to receive the openbook 11, the eyelets 8, when the device is so used, engaging the outer ends of the'slots 9. Thestrip 5 being wider than the strip 7, offers more resistance The specific construction' of the COMBINED RULER ANDBOOK HOLDER.

against flexure than the strip 5, even though it is made from the same material. When the strip 7 has been flexed, its outer face adjacent the slots 9 engages the under sides of the flanges 10 with considerable friction, l

preventing relative longitudinal movement, and the strip 5, which remains comparatively straight, acts as a brace to hold the book open.

from inexpensive material, such as bristol board, or, preferably, vulcanized 'fiber, so that the entir'e device may be cheaply manufactured and given away for, the purpose of advertising. One or both faces may be inscribed with suitableadvertising matter,

as indicated at 12. The strip 5 may be used as a ruler, and the device as'a whole may be used to hold an open book, as shown in Figure 1, or may be used for holding loosesheets of paper in a similar manner, the.

device 'when so used being preferably arranged with the strip 7 uppermost. Being flexible the device may be used for measurpreferred embodiment of the invention, it

will" be'understood that various modifica tions' may be made in form and material, of the without departing from the scope invention as claimed.
