Abstract
An easel hinge for supporting picture frames and the like comprising an outer hinge plate and an inner hinge plate, both having curled barrels, the inner barrel being positioned within the outer barrel for relative rotational movement therewith without the use of a separate hinge pin. At least one opening is provided in the outer barrel and a tang is provided projecting upwardly from the inner barrel and extending into said outer barrel opening. The full arcuate separation between the plates causes the tang to engage a lower edge of the opening in the outer plate to limit the degree of angular separation between the plates.
