Abstract
A device for setting, adjusting, and measuring a force in a system, including a first portion for measuring a system force at a first end of the device and including a measurement means, a second portion for adjusting or setting the system force at a second end of the device and including an adjustment means, a housing where the first portion corresponds to the first end of the housing and the second portion corresponds to the second end of the housing, a resilient means within the measurement means for generating a resistance force, and a visual means for indicating an amount of the system force that is related to the physical position of the adjustment means and the resistance force created by the resilient means.
Claims17
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.

A device for setting, adjusting, and measuring tension in a cable system having one or more cables, comprising:
- a frame housing having a set of scale markings market thereon for indicating a level of tension in said cable system, an adjustment end, and a measurement end at an opposite end of said frame housing from said adjustment end;
- a sliding measurement member configured 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, configured to operatively adjust said tension in said cable system, comprising adjustment threads on one end and disposed inside said frame housing and an adjustment member attachment portion 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 such as to change a distance between said adjustment end and said measurement end in response to rotational turning force applied to at least one of said threaded adjustment member and said frame housing, such that the tension in the cable 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 compression spring 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, configured to generate a spring force for measurement of said tension in said cable system;
- a flat indicator positioned within said frame housing at the end of said compression spring at said locking insert member, configured to retain said end of said compression spring, and for visually marking the tension in said cable system.

A device for setting, adjusting, and measuring tension in a system, comprising:
- a frame housing having a set of scale markings 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 operable for slipping 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, for adjusting 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 such as to change a distance between said threaded adjustment end and said measurement end in proportion to an amount of rotational turns applied to at least one of said adjustment member and said frame housing, such that the tension in the system is changed in proportion to the change in distance;
- 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;
- and
- a flat indicator positioned within said frame housing at the end of the resilient member, operable for retaining said end of said resilient member and for visually marking the tension in the system.
