Abstract: The disclosure concerns a device for clamping two axially telescoping rods in a selected telescoped position, wherein the device includes a case supported at the end of the outside one of the two rods and the case encloses an annular bush wrapped around the inside one of the two rods. One side of the bush is open for defining an axial gap. Terminal flanges extend away from the bush at opposite sides of the gap. A shaft extends from the second of the terminal portions, through the first of the terminal portions and then outside the case. A two-position cam is journaled to the shaft and is shaped to engage the exterior of the case. As the cam is moved between its two positions, it selectively draws the terminal portion flanges together or permits them to move apart for selectively clamping or releasing the bush on the rod. A spring normally biases the terminal portion flanges apart.

Abstract: A locking mechanism for securing the upper housing of an annular blowout preventer to the lower housing. A split latch ring having a plurality of angled teeth cut in its outer diameter is expandable into the lower housing which is provided with a plurality of locking grooves contoured to mate with the teeth. A locking ring with a tapered outer surface mates with a tapered inner surface on the latch ring for expanding the latch ring. Bolting the inner locking ring to the upper housing causes downward movement of the locking ring forcing the latch ring outwardly and down the taper of the engaging teeth. The upper housing is locked to the lower housing as the upper housing has a shoulder engaging the lower edge of the downwardly moving latch ring causing seating of the upper housing on to the lower housing and compensating for variations in machining tolerances.
