Abstract

An adjustable bent housing consisting of an inner housing telescopically received within an outer housing. A
sleeve is provided having an angularly offset clutch face.
Spline non-rotatably couple an interior surface of the sleeve with an exterior surface of the inner housing. The sleeve is axially slidable along the exterior surface of the inner housing between an inoperative position wherein the sleeve is spaced from the outer housing and an operative position. In the operative position the angularly offset clutch face of the sleeve engages an angularly offset clutch face on the outer housing thereby non-rotatably coupling the inner housing and the outer housing in a bent position the magnitude of which is dependent upon the relative rotational positioning of the outer housing and the inner housing. A
first annular member, having a concave radiused contact surface, projects from the exterior surface at the first end of the inner housing. A second annular member having a convex contact surface projects from the interior surface at the second end of the outer housing. The convex contact surface of the second annular member engaging the concave contact surface of the first annular member thereby preventing axial separation of the inner housing and the outer housing while accommodating the bend created when the sleeve is secured in the operative position. A locking nut is threadedly engageable with the exterior surface of the inner housing to secure the sleeve in the operative position.
