Abstract: A clamping device for removably attaching a transducer of the probe type to a gage comprises a block having a first end attached to the body of the gage and a second end spaced slightly therefrom, with a tunnel between the two ends aligned with a matching tunnel through the gage body. The gage body tunnel closely surrounds the tubular stem of the gage, while the block tunnel is slightly radially spaced therefrom. A clamping bolt draws the second end down into engagement with the gage body, which creates an axial misalignment of the tunnels to bring the block tunnel wall into clamping engagement with the probe, the misalignment and clamping force controlled by the spacing of the second end.

Abstract: A tube feeder has a longitudinal support equipped with two rows of wheels which support various diameter tubes and a loader for delivering tubes one at a time to the wheels. The loader comprises transverse tracks mounted on the longitudinal support and cooperating lifter blades associated with an inclined storage rack. The height of the longitudinal support is adjustable to locate the centerlines of various diameter tubes on the same fixed centerline. As the height of the longitudinal support is adjusted for a particular diameter tube, the loader is automatically adjusted to handle tubes of the same diameter.
