Abstract
A tension meter having a central feeler arm mounted on a base for movement of at least a portion thereof relatively thereto, sensing means mounted on the base for sensing movement of the central feeler arm movable portion and a pair of parallel side feeler arms positioned on opposite sides of the central feeler arm and generally parallel thereto, the side feeler arms being mounted on the base for simultaneous movement away from the central feeler arm into inoperative position for receiving a sheet or strand to be measured and toward the central feeler arm in operative position to measure the tension of the sheet or strand. For moving the sensing means responsive to the feeler arm movable portion, cam and follower means may be interposed therebetween.
Claims6
A tension meter comprising
- a base
- a central feeler arm mounted on said base for movement of at least a portion thereof relatively thereto
- sensing means mounted on said base for sensing movement of said central feeler arm movable portion
- a pair of parallel side feeler arms positioned on opposite sides of said central feeler arm and generally parallel thereto and defining a side feeler arm plane
- mounting means for said side feeler arms including a side feeler arm supporting plate mounted on said base for pivotal movement about an axis parallel to said side feeler arm plane, said plate being pivotally movable between an operative position in contact with said base and an inoperative position away from said base and supporting said side feeler arms for simultaneous pivotal movement on said base away from said central feeler arm into inoperative position for receiving a sheet or strand to be measured and toward said central feeler arm in operative position to measure the tension of said sheet or strand by moving the movable portion of said central feeler arm, and
- releasable locking means for locking said plate in contact with said base with said side feeler arms in said operative position, said releasable locking means including a transverse pin member mounted on said plate and an operating lever pivotally mounted on said base, said operating lever being pivotally movable toward said base into operative position and having a hook portion engaging said pin member to move said plate into its operative position in contact with said base.

A tension meter comprising
- a base
- a central feeler arm having a longitudinal axis, said feeler arm having a fixed portion mounted on said base and a movable portion integrally connected to said fixed portion and having a sheet or strand contacting roller mounted on the free end thereof, said movable portion being movable in a direction generally perpendicular to said central feeler arm longitudinal axis
- sensing means mounted on said base for sensing movement of said central feeler arm movable portion, said sensing means having a sensing element movable in a direction generally parallel to said central feeler arm longitudinal axis
- cam and follower means interposed between said sensing element and the movable portion of said central feeler arm for moving said sensing element responsive to movement of said feeler arm portion, said cam and follower means including a cam surface follower mounted on said sensing element, a supporting member having a transversely extending bore generally perpendicular to said central feeler arm longitudinal axis mounted on the movable portion of said central feeler arm, a cylindrical cam member having a generally flat cam surface portion rotatably mounted in said bore for angular adjustment of said cam surface portion and clamping means on said supporting member for locking said cam member in its angularly adjusted position
- a pair of parallel side feeler arms positioned on opposite sides of said central feeler arm and generally parallel thereto and defining a side feeler arm plane, each said side feeler arm having a sheet or strand contacting roller mounted on the free end thereof
- mounting means for said side feeler arms including a side feeler arm supporting plate mounted on said base for pivotal movement about an axis parallel to said side feeler arm plane, said plate being pivotally movable between an operative position in contact with said base and an inoperative position away from said base and supporting said side feeler arms for simultaneous pivotal movement on said base away from said central feeler arm into inoperative position for receiving a sheet or strand to be measured and toward said central feeler arm in operative position with said sheet or strand contacting rollers in contact with said sheet or strand to measure the tension of said sheet or strand by moving the movable portion of said central feeler arm
- releasable locking means for locking said plate in contact with said base with said side feeler arms in said operative position, said releasable locking means including a transverse pin member mounted on said plate and an operating lever pivotally mounted on said base, said operating lever being pivotally movable toward said base into operative position and having a hook portion engaging said pin member to move said plate into its operative position in contact with said base, and
- compression spring means interposed between said plate and said base normally urging said plate into its inoperative position away from said base, said lever into its inoperative position away from said base and said side feeler arms away from said central feeler arms into their inoperative position.
