ABSTRACT:
A tensioning device for enabling application of a variable tension that may be securely maintained against an artist's canvas mounted on stretcher bars. The tensioning assembly includes a bracket member provided with a pair of ears or the like for threadably mounting an adjusting screw which may be locked upon appropriate adjustment. Preferably, a pair of tensioning devices are provided at intersecting corners of conventional mitered tongue and groove stretcher bars such that each device rigidly affixed to a corresponding bar is disposed to apply an adjustable and readily maintainable tension to the adjacent bar upon appropriate adjustment of respective adjusting screws. In this manner, a canvas or other flexible member affixed to the stretcher bars may be stretched to a desired extent by application of a carefully controlled tensioning force applied by adjusting screws.
