Claim:
A device for setting, adjusting, and measuring tension in a system, comprising: a frame housing having a set of scale markings fixed thereon for indicating tension, an adjustment end, and a measurement end at an opposite end of said frame housing from said adjustment end; a sliding measurement member operative to slip in the longitudinal and rotational axes through an opening in said measurement end of said frame housing, comprising an attachment portion extending outside of said frame housing and a shaft portion disposed partially inside said frame housing; a threaded adjustment member at said adjustment end, operative to adjust said tension in said system, comprising adjustment threads on one end and disposed inside said frame housing and an adjustment member attaching means on another end extending outside of said frame housing, and wherein said threaded adjustment member is rotatable in interface with threads formed in an opening of said adjustment end of said frame housing for changing a distance between said adjustment end and said measurement end in response to rotational turns applied at least one of said threaded adjustment member and said frame housing, such that the tension in the system is changed in proportion to the change in distance; a locking insert member disposed at an end of said shaft portion of said sliding measurement member; a resilient member retained inside said frame housing, having one end nearest to said attachment portion of said sliding measurement member and another end at the opposite end of said sliding measurement member at said locking insert member; and an indicator positioned within said frame housing at the end of the resilient member at said locking insert member, configured to retain said end of said resilient member and to visually mark said tension in said system.
