A quick action band saw blade tensioning device is disclosed. The band saw blade tensioning device is used in a band saw machine having at least upper and lower band saw supporting wheels operatively rotatably mounted to a supporting frame. The band saw blade tensioning device includes a wheel support pivotally mounted to the supporting frame about a wheel support pivotal mount, one of the upper and lower band saw supporting wheels being rotatably mounted to the wheel support about a wheel support rotatable mount, and an adjustable device for pivotally moving the wheel support and its rotatably mounted band saw about the wheel support pivotal mount so as to apply a greater or lesser tensioning force to the band saw as desired. The adjustable device includes an elongated wire spring which is attached to the pivoting wheel support to provide the desired tensioning force to the band saw blade. Tension is maintained by clamping the deflected spring into place.
