upper circular aperture 4 whereas hook 11 is adapted to grip notch 6 within the lower edge portion of clip 2 as illustrated in fig1 the length of elastic band 8 is designed so that the band will be stretched when hooks 9 and 11 are seated within catch member apertures 4 and 6 pencil 15 may then be readily slipped between the lower surface of band 8 and the upper surface of movable clip member 2 pen lights rulers and similar instruments can also be conveniently stored upon the upper clip member and will be maintained in position by the elasticity of band 8 if notch 6 was absent the relatively narrow hook member 11 would be positioned about the lower edge portion 7 of the clip member which could function as a catch member for the hook since the spring force for maintaining the lower edge portion 7 against the pad of paper is considerable the amount of pressure exerted by the lower edge of hook 11 would be very high owing to its small area and such an unduly high pressure could make an undesirable indentation within the paper and would prevent the major length of the lower edge portion 7 from contacting the sheets to distribute the spring force and thus lower the pressure should a base member having a pressure sensitive adhesive thereon together with a.
