7291047, Nov 6, 2007

Filed:

Aug 1, 2006

Appl. No.:

11/496796

Inventors:

Roy Jones - Dayton TX, US
Amy Jones - Dayton TX, US

International Classification:

B63H 5/16

US Classification:

440 71, 416247 A

Abstract:

A shielding apparatus includes a body formed from rigid material that has first and second pivotally conjoined sections removably cradled about the propeller. The body has a fulcrum axis registered parallel to a longitudinal length of the propeller. Each of the sections includes a plurality of cylindrical sleeves linearly juxtaposed end-to-end when the sections are adapted to the closed position. The sleeves receive the locking mechanism therethrough and prevent the first and second sections from pivoting to the open position. A fastener is included for locking the sections together at the closed position. The locking fastener is telescopically interfitted through corresponding distal ends of the sections. The locking fastener is detachable from the body when withdrawn along a linear plane extending parallel to the fulcrum axis such that the locking mechanism remains spaced from the propeller. The locking fastener is coplanar with the fulcrum axis.

International Classification:

E21B 17/10

Abstract:

The downhole friction reducing tool of the present invention includes an integral friction coefficient reducer and is configured to reduce friction in all planes, reduce torque and/or drag continually and reduce frictional wear and damage that can result in loss of integrity to surface areas where it travels. The friction coefficient reducer involves a ball transfer unit having a plurality of roller ball units. The roller ball units include a large-diameter load-bearing roller ball unit and a plurality of smaller-diameter supporting roller ball units.

E21B 34/14

Abstract:

A rotary traveling valve for subterranean pumping system is disclosed herein. The traveling valve includes a rotary lock configured for back and forth rotary motion in response to up stroke and down stroke movements of a driver. The bottom face of the rotary lock rests against a seating face of a housing of the valve, and a fluid passage in the seating face is opened due to rotary motion of the rotary lock during a down stroke movement of the driver, and closed during an up stoke movement of the driver. The bottom face of the rotary lock is pressed against the sealing face by a back pressure spring to prevent excessive bottom pressure to cause pumping interruption due to gas and fluid blow-by through the valve. It also compensates for any wear that may take place on the two surfaces. In addition traveling valve incorporates bearing balls to minimize friction between moving parts such as driver and housing as well as between driver and rotary lock.
