发明名称 Method and means of straightening cycle frames
摘要 The means of this invention comprises a rectangular cage means including spaced apart frame members adapted to receive the cycle frame therein. A plurality of length adjustable support members are secured to the frame members for supporting and positioning the cycle frame relative to the cage means. A hydraulic ram is selectively adjustably secured to the frame members as required and includes a rod portion adapted to engage the cycle frame to deflect or bend the same upon actuation of the ram means. A device is also disclosed for straightening the frame head portion of the cycle frame and for determining if the frame head has been properly vertically aligned and to determine if the frame has the proper rake angle. The method of straightening the cycle frame is also disclosed.
