Abstract
The tall flange rubber adapter attaches to the inner barrel of a rotating head assembly. A rubber attaches to the tall flange rubber adapter. The rubber secured to the rubber adapter also rotates with the inner barrel thus maintaining the seal with the drill string to divert the drilling fluid from the well to the outlet flange. Fasteners install upward into the adapter and the inner barrel to secure the rubber adapter with the inner barrel. The increased height of the rubber adapter provides additional surface for the fastener to contact. The increased contact of the fastener with the tall flange maintains the fastener within the rubber adapter and the inner barrel to limit fasteners from falling downhole into the drilling area.

An apparatus for securing a rubber to a rotating drilling assembly, wherein the rotating drilling assembly is configured to accept a drilling string passing vertically through the rotating drilling assembly, the apparatus comprising:
- an attachment adapter that attaches to the rotating drilling assembly to secure the rubber with the rotating drilling assembly, the attachment adapter having an outer edge;
- a central aperture of the attachment adapter configured to allow passage of the drilling string vertically through the attachment adapter;
- an outer fastener aperture located interior of the outer edge of the attachment adapter, the outer fastener aperture configured to accept an outer fastener inserted downward through the attachment adapter to secure the rubber vertically below the attachment adapter;
- and
- an inner fastener aperture located laterally interior of the outer fastener aperture wherein the inner fastener aperture configured to accept an inner fastener to secure the attachment adapter to the rotating drilling assembly.
An apparatus for securing a rubber to an inner barrel of a rotating drilling assembly, wherein the rotating drilling assembly is configured to accept a drilling string passing vertically through the rotating drilling assembly, the apparatus comprising:
- an attachment adapter that attaches to the rotating drilling assembly to secure the rubber with the rotating drilling assembly, the attachment adapter having a bottom surface;
- a central aperture of the attachment adapter configured to allow passage of the drilling string vertically through the attachment adapter;
- an outer fastener aperture located laterally outward from the central aperture, wherein the outer fastener aperture passes through the bottom surface of the attachment adapter, wherein the outer fastener aperture configured to accept an outer fastener through the bottom surface to secure the rubber at the bottom surface for rotating the rubber with the rotating drilling assembly;
- and
- an inner fastener aperture located laterally between the central aperture and the outer fastener aperture, wherein the inner fastener aperture configured to accept an inner fastener to secure the attachment adapter to the rotating drilling assembly.
An apparatus for securing a rubber to an inner barrel of a rotating drilling assembly, wherein the rotating drilling assembly is configured to accept a drilling string passing vertically through the rotating drilling assembly, the apparatus comprising:
- an attachment adapter that attaches to the rotating drilling assembly to secure the rubber with the rotating drilling assembly;
- a central aperture of the attachment adapter configured to allow passage of the drilling string vertically through the attachment adapter;
- a bottom surface of the attachment adapter;
- an outer fastener aperture located radially outward from the central aperture, wherein the outer fastener aperture passes through the bottom surface of the attachment adapter, wherein the outer fastener aperture configured to accept an outer fastener through the bottom surface to secure the rubber at the bottom surface, wherein the fastener passing through the outer fastener aperture inserts into the rubber and terminates prior to passing through the rubber;
- an inner fastener aperture located laterally interior of the outer fastener aperture wherein the inner fastener aperture configured to accept an inner fastener to secure the attachment adapter to the rotating drilling assembly.
