Abstract:
The present invention provides an apparatus for measuring the shear strength of rubber bonded to a metal insert in a valve seal, said apparatus comprises an upper fixture and a lower fixture. A mounting device is disposed in the lower fixture of the apparatus for retaining the valve seal. A shearing means is disposed in the upper fixture of the apparatus for shearing the rubber bonded to the metal insert. The shearing means has an arcuate edge for contacting the valve seal. There is a first means engageable with the shearing means for controlling its movement in one of a downward motion for shearing the valve seal and an upward motion for returning the shearing means to its starting position. Further there is a second means for recording the movement of the shearing means and the force that is applied by such first means until a bond between the rubber and the metal insert of the valve seal is broken.
