DETAILED DESCRIPTION In keeping with the foregoing there is provided in accordance with the present invention a portable device for resurfacing in situ a fifth wheel king pin depending from the underside of a transport trailer.
The device includes an elongate member which during use of the device extends from the pin to be resurfaced to a surface or floor below the pin, and includes preferably toward its upper end means such as a shallow cup shaped socket, centering protrusion or the like for engaging the pin.
The centering protrusion on the upper end of the elongate member may be receivable in a complimentary hollow in the pin.
The device also includes a first arm pivotably mounted on and extending horizontally from the elongate member.
Preferably, the first arm extends from the upper part of the elongate member.
A second arm is movably, preferably pivotably, mounted on the first arm.
Alternatively, the second arm may be slidably mounted on the first arm.
The second arm preferably extends horizontally from a part of the first arm remote from the elongate member.
The second arm includes means for resurfacing the pin as the first arm is pivoted about the elongate member, such as a power driven grinder, which is preferably adjustably mounted on a part of the second arm remote from the connection of the second arm with the first arm.
The device also includes means for adjusting the vertical position of the grinder relative to the pin when the device is in use.
The device also includes means for adjustably positioning the second arm relative to the first arm, and the elongate member may comprise a vertically adjustable jack post.
