Abstract: A clevis including: bridge portion; a neck portion extending from the bridge portion in a first axial direction; a threaded opening passing through the bridge and neck portions through which a longitudinal axis passes; and first and second folded sidewalls extending from the bridge portion in a second axial direction, opposite the first axial direction. The first side wall includes: a first portion at a first distance, in a radial direction orthogonal to the longitudinal axis, from the longitudinal axis; and a second portion at a second distance, in the radial direction, less than the first distance, from the longitudinal axis and including at least one hole. The second side wall includes: a third portion at the first distance, in the radial direction, from the longitudinal axis; and a fourth portion at the second distance, in the radial direction, from the longitudinal axis and including at least one hole.

Abstract: A clevis including a bridge portion, a cylindrically shaped neck formed from the bridge, and folded side walls extending from the bridge portion in a first direction. One side wall includes a first hole and a first surface parallel to a longitudinal axis. The other side wall includes a second hole and a second surface facing the first surface. The clevis includes a threaded opening, in the bridge and neck, aligned with the axis and a space formed by the bridge and side walls. The neck is formed from the bridge portion in the first direction or is formed from the bridge portion in a third direction, opposite the first direction. The material includes one only single piece of low carbon steel. The first and second surfaces are parallel to the longitudinal axis.

Abstract: An automatic slack adjuster includes a clutch assembly and a disengaging assembly for disengaging the clutch assembly such that an end of a worm shaft may be freely rotated for adjustment purposes. In a preferred embodiment, the clutch assembly is formed from rotor and coupling structures of the automatic slack adjuster, and the disengaging assembly is a pin that separates the rotor and the coupling. In a preferred embodiment, a spring biased button may be depressed to actuate the pin to cause the separation of the rotor and the coupling thereby allowing an end of the worm shaft to be freely rotated.

Abstract: An automatic slack adjuster operating to effect reduction of slack present in a vehicle brake system upon brake release incorporates a member cooperating with a slack adjusting rotor to determine a reference position for the rotor and to return the rotor to such reference position at the completion of each brake operational cycle.

Abstract: A gage for use in mounting a slack adjuster having one end having an opening adapted to removably couple the slack adjuster to a brake control shaft and an opposite end having an opening adapted to removably receive a bearing pin for rotatably coupling the slack adjuster to a clevis adjustably mounted on a brake actuating push rod, wherein the gage includes an elongated body having first and second ends, the first end having a first bearing surface adapted to engage with an outer surface of the control shaft, and the second end having a second bearing surface adapted for engagement with the bearing pin and an indicator for indicating when the position of the clevis lengthwise of the push rod provides a given angle between an axis extending lengthwise of the push rod and a line drawn through centers of the control shaft and the bearing pin.
