  • Automatic die clamp
    Patent number: 4743002
    Abstract: An improved mechanism for automatically clamping a die tool to a press bed or press ram. The automatic die clamp is self-locking and self-compensating to provide a failsafe operation in the clamped position and thus the mechanism retains the clamp in the clamped position. A ramp is provided to guide the movement of a wedge which wedge movement controls the movement of a clamping member. A spring bias may be provided as an optional feature to assist in the self-locking. Release of the clamp requires the application of an external force to overcome the locking of the teeth.

  • Mechanical quill having selective braking capability
    Patent number: 4546834
    Abstract: A mechanical quill having selective braking capability, achieved by a pneumatic cylinder (110) mounted to one motor (80) for selectively driving a braking member (120) into a braking material (104) coupled to a motor armature (84). This braking member (120) interrupts a clutch-type drive path through the motor as desired, to prevent advance of a quill.
